Infantile spasms, newly classified as infantile epileptic spasm syndrome (IESS), occur in children under 2 years of age and present as an occur as brief, symmetrical, contractions of the musculature of the neck, trunk, and extremities. When infantile spasms occur with a concomitant hypsarrhythmia on electroencephalogram (EEG) and developmental regression, it is known as West Syndrome. There is no universally accepted mainstay of treatment for this condition, but some options include synthetic adrenocorticotropic hormone (ACTH), repository corticotropin injection (RCI/Acthar Gel), corticosteroids, valproic acid, vigabatrin, and surgery. Without effective treatment, infantile spasms can cause an impairment of psychomotor development and/or cognitive and behavioral functions. The first-line treatment in the USA is ACTH related to high efficacy for cessation of infantile spasms long-term and low-cost profile. Acthar Gel is a repository corticotropin intramuscular injection that became FDA-approved for the treatment of IESS in 2010. Though it is believed that ACTH, Acthar Gel, and corticosteroids all work via a negative feedback pathway to decrease corticotropin-releasing hormone (CRH) release, their safety and efficacy profiles all vary. Vigabatrin and valproic acid are both anti-seizure medications that work by increasing GABA concentrations in the CNS and decreasing excitatory activity. Acthar Gel has been shown to have superior efficacy and a diminished side effect profile when compared with other treatment modalities., (© 2023. Fondazione Società Italiana di Neurologia.)

Acthar ® Gel (repository corticotropin injection) is a naturally sourced complex mixture of adrenocorticotropic hormone analogs and other pituitary peptides that is believed to have both steroidogenic and nonsteroidogenic immunomodulatory effects via activation of melanocortin receptors in various cells throughout the body. Since 1952, Acthar has been approved by the US Food and Drug Administration to treat a variety of autoimmune and inflammatory diseases. Since 2014, Mallinckrodt Pharmaceuticals has conducted a large number of preclinical, clinical, and real-world-evidence studies of Acthar for the treatment of rheumatoid arthritis, systemic lupus erythematosus, dermatomyositis and polymyositis, multiple sclerosis relapse, ophthalmic disorders, sarcoidosis, and nephrotic syndrome. To date, Acthar has been the subject of more than 500 publications, many of which demonstrate the safety and efficacy of Acthar in patients with inflammatory diseases for whom standard treatments were ineffective or intolerable. Here, we review the history of Acthar and the findings of studies that have investigated the mechanism of action, safety, efficacy, and real-world effectiveness of Acthar for the treatment of inflammatory diseases., (© 2023.

Objective: Although the suppressive action of synthetic steroids on the hypothalamus-pituitary-thyroid (HPT) axis is established, little is known regarding the effect of the administration of synthetic adrenocorticotropic hormone (ACTH)., Design: In the context of a randomized, open label, comparative study assessing the efficacy and safety of ACTH and betamethasone in the treatment of hospitalized patients with acute gout, we compared the effects of these agents on thyroid function tests., Methods: Serum TSH, total T4 and T3 and cortisol were measured before and at 24 and 48 h after a single intramuscular dose of synthetic ACTH (1 mg) or betamethasone (6 mg), in 38 hospitalized patients with acute gout and normal thyroid function., Results: The final analysis included 32 patients, due to missing data. The ACTH and betamethasone groups did not differ regarding the mean age, gender, severity of gout attack, and baseline thyroid parameters. In the ACTH group TSH and T4 were significantly decreased at 24 and at 48 h compared to baseline, while T3 was decreased at 24 but not at 48 h. In the betamethasone group T3 remained stable; TSH and T4 decreased significantly from baseline levels at 24 h; at 48 h, TSH had returned to and T4 showed a partial rebound towards pre-treatment values., Conclusions: A single IM administration of 1 mg of synthetic ACTH has more profound and prolonged effects on the HPT axis, lasting for at least 48 h, compared to a single IM dose of 6 mg betamethasone., (Copyright © 2022 Elsevier Inc.

The management of acute gout in the hospital setting may be challenging since most patients are elderly with multiple unstable comorbidities. However, there are no prospective clinical trials for hospitalized patients with gout to guide optimal management. Evidence indicates that steroids or adrenocorticotropic hormone (ACTH) may be effective and safe therapeutic options for these patients. This study aimed at directly comparing the efficacy and safety of ACTH vs betamethasone for the treatment of gout in hospitalized patients. This is the first prospective clinical trial for hospitalized patients with gout. We designed a randomized, open label study to assess the efficacy and safety of a single intramuscular injection of either ACTH or betamethasone in hospitalized patients with acute gout. Primary efficacy endpoints were the change in intensity of pain as recorded using a Visual Analogue Scale (VAS) at baseline compared to 24 h (ΔVAS24h), and 48 h. Moreover, we assessed safety and effects on the hypothalamic-pituitary-adrenal (HPA) axis, glucose and lipid homeostasis, bone metabolism, electrolytes and renal function. 38 patients were recruited. Both treatments were highly effective. The mean ± SE ΔVAS24h and ΔVAS48h for ACTH was 4.48 ± 0.29 and 5.58 ± 0.26, respectively. The mean ± SE ΔVAS24h and ΔVAS48h for betamethasone was 4.67 ± 0.32 and 5.67 ± 0.28, respectively. Direct comparison between the two groups at 24 h and 48 h did not show statistically significant differences. Both treatments were well tolerated and safe. The effects on all metabolic parameters were mostly minimal and transient for both treatments. However, ACTH may affect less the HPA axis and bone metabolism compared to betamethasone, thus leading to the conclusion that. ACTH and betamethasone are effective and safe for the management of acute gout in hospitalized patients but that ACTH may associate with less disturbance of the HPA axis and bone metabolism. Our data support the use of both drugs as first line treatments for hospitalized patients with gout.Clinical trial registration: ClinicalTrials.gov NCT04306653., (© 2022.

History: A 59-year-old woman presented for an endocrinological evaluation of recurrent spontaneous hypoglycemia. The complaints always regressed after carbohydrate intake. Due to classic congenital adrenal hyperplasia, the patient received substitution therapy with hydrocortisone for decades., Findings and Diagnosis: The patient was in good general condition and slightly overweight. The blood glucose at the time of admission was 87 mg/dl. The cortisol and adrenocorticotropic hormone (ACTH) under substitution with delayed-release hydrocortisone were unremarkable. The mixed-meal tolerance test (MMTT, standardized breakfast test) showed no reactive hypoglycemia. In the subsequent 72-hour fast, symptomatic hypoglycemia of 46 mg/dl was demonstrated after 36 hours. The insulin secretion was suppressed. The low cortisol as well as the high ACTH indicated an undersupply of hydrocortisone at this time., Therapy and Course: Initially, the morning dose of delayed-release hydrocortisone was increased. However, this had no effect on blood glucose. Therefore, hydrocortisone was also prescribed at night., Conclusion: In addition to endogenous hyperinsulinism, a disturbance of the contrainsulinergic hormones can also be responsible for spontaneous hypoglycemia.The MMTT and the 72-hour fast test should be used for diagnosis. It is important to ensure that hormone analysis is carried out immediately in hypoglycemia. The ratio of insulin, C-peptide and proinsulin to blood glucose and the constellation of counter-regulatory hormones such as cortisol, ACTH, growth hormone, Insulin-like growth factor 1 (IGF-1) and catecholamines can provide information about the etiology of hypoglycemia., Competing Interests: Die Autorinnen/Autoren geben an, dass kein Interessenkonflikt besteht., (Thieme.

Objectives: Long-term adrenocorticotropic therapy (LT-ACTH), which consisted of 2-4 weeks of daily injections of adrenocorticotropic hormone (ACTH) and subsequent months of weekly injections, was tried for relapsed West syndrome (WS) or other intractable epilepsies in small case reports. Our aim was to explore the efficacy of LT-ACTH for preventing WS relapse, as well as the prevalence of its adverse events., Methods: This is a retrospective, nationwide, multicenter case series of patients with WS who underwent LT-ACTH. Clinical information of the patients and protocol of LT-ACTH were collected from participating institutes in this study. We defined clinical response to ACTH as achievement of hypsarrhythmia and epileptic spasms resolution. Patients who responded to daily ACTH injections were identified and assessed whether they experienced WS relapse during/after the weekly ACTH injection period. The outcome was measured by the nonrelapse rate at 24 months after daily ACTH injections using the Kaplan-Meier method., Results: Clinical information of 16 children with WS was analyzed. The median age at LT-ACTH initiation was 14.5 months (range: 7-68 months). Thirteen (81%) patients had previously undergone conventional ACTH treatment. The LT-ACTH regimens comprised a median of 16 days of daily injections (range: 11-28 days) and 10 months of weekly injections (range: 3-22 months). Seven patients experienced WS relapse during/after subsequent weekly ACTH period, and the nonrelapse rate at 24 months after daily injections was estimated at 60.6% (95% confidence interval: 32.3%-80.0%). Height stagnation, hypertension, and irritability were observed; lethal adverse events were not reported., Significance: Our study firstly explored the efficacy of LT-ACTH for preventing WS relapse. LT-ACTH might be a treatment option for patients with relapsed or intractable WS; however, we note that our study is limited by its small sample size and the lack of an appropriate control group., Competing Interests: None of the authors has any conflict of interest to disclose. We confirm that we have read the Journal's position on issues regarding ethical publication and affirm that this report is consistent with those guidelines., (© 2021 The Authors.

Objective: Bacille de Calmette et Guérin (BCG) is a live vaccine for tuberculosis that is administered to all infants in Japan. Adrenocorticotropic hormone (ACTH) therapy for West syndrome (WS) causes immunosuppression and may result in BCG infection after BCG vaccination. We evaluated the safety of ACTH therapy initiated shortly after BCG vaccination., Methods: We analyzed patients with WS who received ACTH therapy between 2005 and 2018. We evaluated the interval between BCG and ACTH therapy, and the rate of BCG infection during and after ACTH therapy, by retrospective chart review., Results: Seventy-nine patients were included in the analysis. Twenty-three patients received ACTH therapy prior to BCG vaccination. For the remaining 56 patients, the median interval between BCG vaccination and the start of ACTH therapy (BCG-ACTH interval) was 91.5 (range 14-280) days. The BCG-ACTH interval was shorter in patients with unknown than in those with known etiologies. It was <8 weeks in 13 patients (10 with unknown and 3 with known etiologies). The minimum BCG-ACTH interval was 14 days. Six patients with epileptic spasms received BCG vaccinations because physicians did not recognize their seizures. None of the patients developed BCG infection., Conclusion: No patients who received ACTH therapy after BCG, even at an interval of 8 weeks, developed BCG infection. The timing of ACTH therapy initiation should be based on the risk of BCG-related adverse events and the adverse effects of any delay., (Copyright © 2021 Elsevier Inc. All rights reserved.)

We present the rare case of lipomatous atrial septal hypertrophy associated with adrenocorticotropin hormone therapy in an infant with West syndrome, highlighting their relatively benign nature and good prognosis in children, and the relevance of the differential diagnosis with more dangerous cardiac masses in order to avoid aggressive diagnostic and therapeutic interventions.

Objectives: Idiopathic inflammatory myopathies (IIM) are a group of autoimmune diseases characterized by proximal muscle weakness. H. P. Acthar gel [repository corticotropin injection (RCI)] is a formulation of adrenocorticotropic hormone and has been approved by Food and Drug Administration for use in IIM; however, literature is limited. In this study, we report longitudinal follow-up of myositis patients treated with RCI., Methods: Patients with refractory IIM who were enrolled in the prospective, open-label RCI trial were included in this study. The post-trial follow-up period was 6 months with assessments every 2 months, which included myositis core set measures including extra-muscular global, muscle and patient global disease activities, HAQ, and manual muscle testing., Results: Two patients were lost to follow-up after finalization of the trial, and the remaining eight patients were enrolled in the follow-up study. One patient remained on RCI after the trial. In the follow-up period, four of eight patients had flare at on average 4.1 months after the RCI trial. Among the patients who flared, three required an increase in prednisone. One patient was restarted on RCI at 5.5 months, but had minimal improvement after 3 months. Four patients who remained stable continued to satisfy criteria for the definition of improvement through the 6-month follow-up. However, none showed any further improvement in the primary or secondary efficacy outcomes after the initial RCI trial., Conclusion: To our knowledge, this is the first study reporting the follow-up results of patients treated with standard dose and duration of Acthar. We believe that our study will provide the basis for the development of future randomized RCI trials in IIM., (© The Author(s) 2020.

Objective: Standard short adrenocorticotropic hormone (ACTH) stimulation test (SST) has traditionally been used for assessing adrenal gland fuction by intravenous (iv) application. However the iv form is not readily available in all countries, including Turkey. The aim of this study was to evaluate the effectiveness of the intramuscular (im) SST., Methods: Patients underwent im SST with suspected adrenal insufficiency (AI) and hyperandrogenism. The SSTs were done with 250 mcg ACTH (Synacthen Depot ampul, concentration 1 mg/mL). The cases were divided into two groups: suspected AI (group 1 n=87); and hyperandrogenism group (group 2 n=124). Definite AI was defined as peak cortisol <18 μg/dL, suspected AI as a peak cortisol of 18-21 μg/dL and normal result was defined as a peak cortisol ≥22 μg/dL., Results: The mean age of the patients was 11.7±5.2 years. In 164 patients (78%) all of the peak cortisol tests were normal (≥22 mcg/dL). The rates were 64% and 88% in group 1 and 2, respectively. Only 8.5% (n=18) of all cases had an inadequate peak cortisol response of <18 mcg/dL. On follow up, 15 patients whose peak cortisol was <18 mcg/dL needed cortisol therapy. Of all cases 3.3% (n=8) had 17-OHP ≥10 ng/dL. Clinical findings suggestive of non-classical congenital adrenal hyperplasia and/or mutation were found in six of these cases (75%). No local and systemic side effects or allergic reactions were observed in any patient., Conclusion: IM ACTH SST is a safe, effective and reliable test in children with suspected AI. There were no local or systemic side effects, supporting the reliability of the im ACTH test.

Infantile spasms (IS or epileptic spasms during infancy) were first described by Dr. William James West (aka West syndrome) in his own son in 1841. While rare by definition (occurring in 1 per 3200-3400 live births), IS represent a major social and treatment burden. The etiology of IS varies - there are many (>200) different known pathologies resulting in IS and still in about one third of cases there is no obvious reason. With the advancement of genetic analysis, role of certain genes (such as ARX or CDKL5 and others) in IS appears to be important. Current treatment strategies with incomplete efficacy and serious potential adverse effects include adrenocorticotropin (ACTH), corticosteroids (prednisone, prednisolone) and vigabatrin, more recently also a combination of hormones and vigabatrin. Second line treatments include pyridoxine (vitamin B6) and ketogenic diet. Additional treatment approaches use rapamycin, cannabidiol, valproic acid and other anti-seizure medications. Efficacy of these second line medications is variable but usually inferior to hormonal treatments and vigabatrin. Thus, new and effective models of this devastating condition are required for the search of additional treatment options as well as for better understanding the mechanisms of IS. Currently, eight models of IS are reviewed along with the ideas and mechanisms behind these models, drugs tested using the models and their efficacy and usefulness. Etiological variety of IS is somewhat reflected in the variety of the models. However, it seems that for finding precise personalized approaches, this variety is necessary as there is no "one-size-fits-all" approach possible for both IS in particular and epilepsy in general., Competing Interests: Declaration of Competing Interest Dr. Jana Velíšková is partially supported by the NS-092786 from the National Institutes of Health, Bethesda, MD, USA.

Introduction: Disease-modifying antirheumatic drugs (DMARDs) have significantly improved clinical symptoms and quality of life with reduced disease progression in many patients with rheumatoid arthritis (RA). Short-term glucocorticoid therapy is often used initially in combination with DMARDs, but some patients still have difficulty reaching treatment goals. Repository corticotropin injection (RCI, Acthar® Gel) is approved as adjunctive therapy for short-term administration in patients with continued RA disease activity., Areas Covered: To determine the safety of RCI in the treatment of RA, adverse events (AEs) from a recent clinical trial of RCI as an adjunctive therapy along with DMARDs and glucocorticoids (ClinicalTrials.gov identifier NCT02919761) were compared with AEs reported in randomized clinical trials of DMARDs and glucocorticoids alone. A systematic review of the literature yielded 4 articles describing the detailed safety results of DMARD/glucocorticoid combination therapy used in the treatment of RA for comparison., Expert Opinion: There were no clinically significant differences between the AE profiles of RCI/DMARD/glucocorticoid treatment in the RCI clinical trial and those in the DMARD/glucocorticoid safety profile compiled from the reviewed clinical trials; this was supported by pharmacovigilance data. These results support the short-term safety of RCI as an adjunctive therapy for patients with persistently active RA.

Background: Renal calcified lesions are known as one of the complications during adrenocorticotropic hormone (ACTH) therapy for intractable epilepsy. However, laboratory changes during the therapy or laboratory features of high-risk cases with renal calcified lesions are yet to be clarified., Methods: In this study, 43 patients with West syndrome aged ≤2 years were included. We retrospectively reviewed age and body mass index at the beginning of ACTH therapy, as well as the amount of fluid intake, daily urinary volume, and laboratory data during therapy. In addition, we studied the urinary sediment of the cases with renal calcified lesions diagnosed by computed tomography., Results: After initiating ACTH treatment, urinary calcium (Ca)/creatinine ratio and urinary pH increased within 2 weeks. Urinary crystals and renal tubular epithelial cells (RTECs) in urinary sediment were frequently found in most cases. Urinary Ca levels, proteinuria or frequency of urinary crystals, and number of RTECs in the urinary sediment were significantly higher in patients with epithelial casts (ECs) or hematuria than in patients without these findings. Among the seven patients who underwent abdominal CT, ECs or hematuria were found only in those with renal calcified lesions. These findings suggested that patients with ECs or hematuria were more likely to have calcified lesions., Conclusions: The risk of renal calcified lesions increased after 2 weeks of ACTH treatment. Abnormal findings in urinary sediments might be an early sign of renal calcification during ACTH therapy., (© 2020 Japan Pediatric Society.)

In patients treated with repository corticotrophin injection (RCI) for pulmonary sarcoidosis, effective management of adverse events may improve adherence. However, management of adverse events may be challenging due to limitations in real-world clinical experience with RCI and available published guidelines.We surveyed 12 physicians with a modified Delphi process using three questionnaires. Questionnaire 1 consisted of open-ended questions. Panellists' answers were developed into a series of statements for Questionnaires 2 and 3. In these, physicians rated their agreement with the statements using a Likert scale.Key consensus recommendations included a starting dose of 40 units twice a week for patients with less severe disease, continued at a maintenance dose for patients who responded, particularly those with chronic refractory sarcoidosis. Panellists reached consensus that concomitant steroids should be quickly tapered in patients receiving RCI, but that concomitant use of immunosuppressive medications should be continued. Panellists developed consensus recommendations for adverse event management, and reached consensus that RCI should be down-titrated or discontinued if other interventions for the adverse effects fail or if the adverse effect is severe.In the absence of clinical evidence, our Delphi consensus opinions may provide practical guidance to physicians on the management of RCI to treat pulmonary sarcoidosis., Competing Interests: Conflict of interest: F.F.

Objectives: Neuromyelitis optica (NMO) has a complex pathology. Clinical symptoms, derived from damage to optic nerves and spinal cord, cause optic neuritis and/or longitudinally extensive myelitis. Treatment options are limited. We assessed adrenocorticotropic hormone (ACTH) use in patients developing exacerbations on systemic steroid treatment and declining other treatments., Methods: Patients with NMO who initiated intravenous methylprednisolone (IVMP) for exacerbations and experienced a subsequent exacerbation on monthly IVMP or had inadequate response to IVMP received ACTH 80 U/d intramuscularly for 7 days (for acute relapse), followed by 80 U every 2 weeks (for long taper down/maintenance). Every 1 to 3 months, relapse, Expanded Disability Status Scale, laboratory, and adverse event assessments were performed., Results: Six patients (mean age: 48.6 years; NMO-suggestive clinical/imaging presentations; cerebral spinal fluid revealing no oligoclonal bands; aquaporin-4 positive [n = 5]) were identified: 5 experiencing subsequent exacerbations with monthly IVMP and 1 with inadequate response to IVMP. No relapses occurred during ACTH treatment or taper-down period, laboratory values indicated no safety concerns, and annual follow-up magnetic resonance imagings were stable. Adverse events were generally characterized as improved or unchanged versus with IVMP, although 1 patient reported transient edema (lower extremities) only during ACTH treatment. Potential treatment-related AEs included edema, acne, urinary tract infection, and insomnia and were reportedly less severe with ACTH treatment than IVMP., Conclusions: Adrenocorticotropic hormone treatment for acute NMO was associated with clinical improvement, suggesting that ACTH could have a role in treating acute NMO patients failing IVMP and declining other treatments. Fewer/less severe AEs were observed with ACTH versus IVMP. Larger, controlled clinical studies are needed.

Background: There is ongoing debate regarding the comparative effectiveness of adrenocorticotropic hormone and prednisolone in the treatment of infantile spasms. With a large cohort and extended follow-up, we set out to evaluate a protocol in which adrenocorticotropic hormone is reserved for prednisolone nonresponders., Methods: The following standardized hormonal therapy protocol was adopted. Patients initially receive prednisolone (8 mg/kg/day [maximum 60 mg/day], divided in three daily doses for 14 days). Prednisolone responders taper it over 14 days, whereas prednisolone nonresponders immediately transition to natural adrenocorticotropic hormone (150 U/m 2 /day, divided in two daily doses for 14 days). We evaluated short-term response, defined as video-electroenecphaloagraphy-confirmed resolution of both epileptic spasms and hypsarrhythmia on day 14, without relapse for 28 additional days. We then evaluated long-term relapse and calculated the rates of sustained response at six, 12, and 18 months., Results: We identified 102 children with infantile spasms who were treated with prednisolone. Prior exposure to hormonal therapy and vigabatrin was observed among 12% and 35% of patients, respectively. Sixty (59%) patients responded to prednisolone, and 13 (33%) prednisolone nonresponders then responded to adrenocorticotropic hormone. Cumulative response to prednisolone and adrenocorticotropic hormone (if needed) was higher among treatment-naive patients (84%) than among patients with prior exposure to first-line treatment (51%), with P < 0.001. Relapse was relatively common among all subgroups., Conclusion: Short-term response to prednisolone was favorable and higher among treatment-naive patients. These data suggest that prednisolone is a reasonable approach to initial therapy and that adrenocorticotropic hormone exhibits substantial efficacy after prednisolone failure., (Copyright © 2019 Elsevier Inc.

Background: Adrenocorticotrophic hormone (ACTH)-treatment rat model has been utilized as a widely accepted model of treatment-resistant depression. Metabolomic signatures represent the pathophysiological phenotype of diseases. Recent studies in gut microbiota and metabolomics analysis revealed the dramatic role of microbiome in psychoneurological system diseases, but still, the mechanisms underlying gut microbiome-host interaction remain unclear., Methods: Male Wistar rats were s.c. injection of ACTH fragment 1-24 for 14 days to induce treatment-resistant depression. Depression-related behavioral tests, analysis of serum monoamine neurotransmitters and hypothalamic-pituitary-adrenal (HPA) axis-related hormones were determined for assessment of ACTH-induced depression rat model. A gas chromatography-time-of-flight mass spectrometer based urinary metabolomic signatures integrated 16S rRNA sequence analysis based gut microbial profiling was performed, as well as Spearman's correlation coefficient analysis was used to manifest the covariation between the differential urinary metabolites and gut microbiota of genus level., Results: Chronic injection of ACTH-induced depression-like phenotype (increased immobility time in forced swimming test and tail suspension test) was accompanied by peripheral serotonin down-regulation and HPA axis overactivation (ACTH and corticosterone up-regulation). Urinary metabolomics analysis indicated that pyruvic acid, L-threonine, mannitol, D-gluconic acid, 4-hydroxybenzoic acid, D-arabitol, myo-inositol and ascorbic acid levels were reduced in ACTH-treated rats' urine, while hippurate level was elevated. In addition, microbial community profiling revealed bacterial enrichment (e.g. Ruminococcus, Klebsiella) and reduction (e.g. Akkermansia, Lactobacillus) in the ACTH-induced depression rat model. Correlation analysis showed that Akkermansia and Lactobacillus were closely relevant to metabolites myo-inositol and hippurate, which were included in host inositol phosphate metabolism, and phenylalanine, tyrosine and tryptophan biosynthesis., Conclusions: Depression rat model induced by ACTH is associated with disturbance of pyruvate metabolism, ascorbate and aldarate metabolism, inositol phosphate metabolism, glycine, serine and threonine metabolism, and glycolysis or gluconeogenesis, as well as changes in microbial community structure. Gut microbiota may participate in the mediation of systemic metabolomic changes in ACTH-induced depression model. Therefore, integrated metabolomic signatures and gut microbial community profiling would provide a basis for further studies on the pathogenesis of depression.

Gut microbiota dysbiosis has been implicated as a vital element in the development or exacerbation of mental disorders, such as major depressive disorder (MDD). Based on the current interest in the gut-brain axis, we investigate the effects of chlorogenic acid (CGA) on gut microbiota in a rat model of MDD. Depression was induced by the adrenocorticotropic hormone (ACTH, 100 μg per rat) in male Wistar rats, which were intervened with using saline or CGA (500 mg kg-1). Behavioral changes and serum parameters were assessed and fecal samples were analyzed by 16S rRNA gene sequencing. Our studies demonstrated that CGA pretreatment ameliorated depression-like behavior (SPT, FST, TST, and OFT) and serum biochemical levels (5-HT, DA, IL-6, and TNF-α) in ACTH-induced depression rats. In addition, CGA ameliorated the decrease in fecal microbiota diversity in ACTH-treated rats. In particular, at the genus level, the changes in the relative abundance of some key bacteria such as Desulfovibrionales, Desulfovibrio, Klebsiella, Burkholderiales, and Bifidobacterium were modulated by CGA pretreatment. These results indicated that CGA could modify the gut microbial community structure, which may contribute to its antidepressant effects.

Objective: To compare the efficacy and safety of the ketogenic diet (KD) with standard adrenocorticotropic hormone (ACTH) treatment in infants with West syndrome., Methods: In this parallel-cohort (PC) randomized controlled trial (RCT), infants were randomly allocated to KD or high-dose ACTH. Those who could not be randomized were followed in a PC. Primary end point was electroclinical remission at day 28. Secondary end points were time to electroclinical remission, relapse after initial response, seizure freedom at last follow-up, adverse effects, and developmental progress., Results: One hundred one infants were included: 32 in the RCT (16 KD; 16 ACTH) and 69 in the PC (37 KD; 32 ACTH). Electroclinical remission at day 28 was similar between KD and ACTH (RCT: 62% vs 69%; PC: 41% vs 38%; combined cohort: 47% vs 48%; KD vs ACTH, respectively). In the combined cohort, time to electroclinical remission was similar between both treatments (14 days for KD, 16 days for ACTH). However, relapse rates were 16% (KD) and 43% (ACTH, P = 0.09), and seizure freedom at last follow-up was 40% (KD) and 27% (ACTH, P = 0.18). Adverse effects needing acute medical intervention occurred more often with ACTH (30% with KD, 94% with ACTH, P < 0.001). Age-appropriate psychomotor development and adaptive behavior were similar. Without prior vigabatrin (VGB) treatment, remission at day 28 was 47% (KD) and 80% (ACTH, P = 0.02); relapse rates were 29% (KD) and 56% (ACTH, P = 0.13). Consequently, seizure freedom at last follow-up was similar. In infants with prior VGB, seizure freedom at last follow-up was 48% (KD) and 21% (ACTH, P = 0.05)., Significance: The study is underpowered; therefore, its results should be interpreted with caution. KD is as effective as ACTH in the long term but is better tolerated. Without prior VGB treatment, ACTH remains the first choice to achieve short-term remission. However, with prior VGB, KD was at least as effective as ACTH in the short term and was associated with lower relapse rates in the long term; therefore, it represents an appropriate second-line treatment after VGB., (Wiley Periodicals, Inc. © 2019 International League Against Epilepsy.)

Objective: To compare the outcomes of adrenocorticotrophic hormone (ACTH) and Prednisolone therapy in children with West syndrome., Methods: The study was done at a tertiary health centre for children. The pediatric neurologist at the centre enrolled children into the study based on the inclusion and exclusion criteria. They were evaluated in detail, classified according to etiologic type and then, randomly assigned into two treatment groups, either ACTH or Prednisolone. They were followed at regular intervals till 6 mo., Results: There was no difference between ACTH and Prednisolone groups with respect to all the outcomes measured. Cessation of spasms was achieved in 6/15 (40%) in Prednisolone group and 9/18 (50%) in ACTH group (p = 0.3906). The average time for achieving cessation was 6.9 and 8 d in ACTH and Prednisolone groups respectively (p = 0.7902). The relapse rates were 18.18 and 50% in ACTH and Prednisolone groups respectively (p = 0.28). The side-effects profile, subsequent epilepsy rates and improvement in milestones were similar in both the treatment groups., Conclusions: There is no significant difference in children treated with ACTH and Prednisolone. Study results cannot be generalized due to small sample size. However, Prednisolone can be a suitable alternative to ACTH in resource poor settings.

Background: Treatment of focal segmental glomerular sclerosis (FSGS) after kidney transplantation is challenging with unpredictable outcomes. The objective was to investigate the use of adrenocorticotropic hormone (ACTH) analogue gel in kidney transplant recipients with de novo or recurrent FSGS resistant to therapeutic plasma exchange (TPE) and/or rituximab., Methods: We performed a retrospective review of cases of de novo or recurrent resistant FSGS at 2 large US transplant centers between April 2012 and December 2016. Proteinuria was measured by urine protein to creatinine ratio., Results: We identified 20 cases of posttransplant recurrent and de novo FSGS resistant to conventional therapy with TPE and rituximab. Mean ± SD age was 49 ± 15.5 years, 14 (70%) were male, 13 (65%) were whites, and 8 (38%) had previous kidney transplants. Median (interquartile range) of recurrent and de novo FSGS was 3 (0.75-7.5) months posttransplant. The majority of patients, 15 (75%), received TPE as a treatment at the time of diagnosis and 10 (50%) received rituximab, which was started before the use of ACTH gel. There was a significant improvement of urine protein to creatinine ratio from a mean ± SD of 8.6 ± 7.6 g/g before ACTH gel to 3.3 ± 2.3 g/g after the use of ACTH gel (P = 0.004). Ten (50%) patients achieved complete or partial remission., Conclusions: Although, the response varied among the recipients, ACTH gel might be an effective therapy for posttransplant resistant FSGS cases that fail to respond to TPE and rituximab.

Purpose: To analyze the incidence of adrenal suppression and the glucocorticoid (GC) dose per kilogram body weight given in infants treated with standard protocol for topical ophthalmic GCs after congenital cataract surgery., Design: Retrospective, consecutive case series., Participants: All children younger than 2 years of age who underwent operation for congenital cataract between January 2011 and May 2015 in 1 center., Methods: Patient charts were reviewed to collect data on results and timing of a standard corticotropin (adrenocorticotropic hormone [ACTH]) stimulation test and GC dose per kilogram body weight., Main Outcome Measures: Incidence of adrenal suppression in children tested on GC treatment. Glucocorticoid dose per kilogram body weight., Results: Among 26 consecutive infants, 15 (58%) were tested while they were still on GC treatment. Ten of these 15 infants (67%) had adrenal suppression, 2 of whom had obvious clinical signs of Cushing's syndrome and 1 of whom had signs of Addisonian crises during general anesthesia. Eleven of the 26 infants (42%) were tested at a median time of 21 days (range, 6-89) after treatment cessation, and they all had normal test results. Children with suppressed adrenal function had received cumulative GC doses per body weight that were significantly higher the last 5 days before testing compared with children with normal test results. Infants with adrenal suppression were treated with hydrocortisone replacement therapy. Adrenal function recovered after a median of 3.1 months (range, 2.3 months to 2.3 years)., Conclusions: Two thirds of the infants tested during treatment with a standard GC protocol after congenital cataract surgery showed adrenal suppression. There was a significant association between the cumulative daily dose of GCs and the test result. Because adrenal suppression is a serious but treatable condition, we recommend a systematic assessment of adrenal function in infants treated with doses of topical ocular GCs comparable to our regimen and careful evaluations of other treatment regimens., (Copyright © 2018 American Academy of Ophthalmology.

Relapse management is a crucial component of multiple sclerosis care. Acute relapses are defined as new neurological symptoms or worsening of existing symptoms persisting for >24 h that are not attributable to heat, overexertion, or infection. The most commonly used treatment for multiple sclerosis relapse is a 3-5-day course of corticosteroids, primarily intravenous methylprednisolone with or without oral steroid taper. Repository corticotropin injection is also the US FDA-approved option for managing acute relapse, particularly in the patients with inadequate response, intolerability or allergy to corticosteroid treatment; poor venous access; or limited ability to receive home or clinic infusions.

Introduction: Adrenocorticotropic hormone (ACTH) has been commonly used as a first-line treatment for infantile spasms (IS), but its optimal dose and duration are still unclear. This study is the largest retrospective cohort to document the therapeutic efficacy and tolerability for three gradient doses of ACTH in IU/kg/day units in Chinese patients., Objective: The aim of our study was to elucidate the effectiveness and safety of three different low doses and duration of ACTH treatment for IS in China., Methods: We conducted a retrospective, chart review of IS cases that were treated with biologic short-acting ACTH and followed up for at least 6 months at a single center in China between June 2010 and June 2016. In total, 200 children met the inclusion criteria. Cases were divided into three groups according to dosage (1, 1.1-1.9, and 2-4 IU/kg/day). Furthermore, we divided the 2-4 IU/kg/day group into 2-3 and 3.1-4 IU/kg/day subgroups. All groups were evaluated for response rates, relapse rates, and adverse effects., Results: Electroclinical remission by day 14 occurred in 41.4% of infants given 2-4 IU/kg/day and 36.4% of infants given 1.1-1.9 IU/kg/day, compared with only 14.7% of patients given 1 IU/kg/day (p = 0.004 and 0.03, respectively). Prolonging ACTH treatment for up to 28 days improved response by 24% in all 200 infants. Overall, 73.9% of infants receiving 2-4 IU/kg/day responded, significantly higher than the 52.7% responding to 1.1-1.9 IU/kg/day and the 23.5% responding to 1 IU/kg/day (p < 0.01). There was no significant difference in the number of relapses or adverse effects in the three groups. Moreover, in the 2-4 IU/kg/day group, 74.7% of children receiving 2-3 IU/kg/day of ACTH responded, compared with 70% who responded to 3.1-4 IU/kg/day (p = 0.78)., Conclusions: ACTH at a dosage of 2-3 IU/kg/day is superior to 1.1-1.9 and 1 IU/kg/day dosages, is as good as a 3.1-4 IU/kg/day dosage in terms of response rate, and causes no more adverse effects or relapses than other dosages. In addition, prolonging the duration of ACTH treatment can improve response.

Patients with infantile spasms, an intractable epileptic disorder, often are treated with adrenocorticotropic hormone. Legionella pneumophila is a rare cause of pneumonia in children. We describe 2 infants with Legionella pneumonia whose infection occurred within 1 month after starting adrenocorticotropic hormone., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Purpose: The dose of repository corticotropin (RCI) and need for a loading dose in sarcoidosis patients receiving chronic corticosteroids are unclear. We performed a single-blind prospective study, comparing two doses of RCI in sarcoidosis., Methods: Chronic pulmonary sarcoidosis patients receiving prednisone therapy with deterioration by 5% in FVC in the previous year were studied. RCI was administered subcutaneously at a loading dose of 80 units RCI for 10 days. Patients were randomized at day 14 to receive either 40- or 80-unit RCI twice a week. The dose of prednisone was modified by the clinician who was blinded to the patient's dosage of RCI., Results: Sixteen patients completed the full 24 weeks of the study. At week 24, there was a decrease in the dose of prednisone, and improvements in DLCO, King's Sarcoidosis Questionnaire health status and fatigue score. There was no significant change in FVC % predicted. For the PET scan, there was a significant fall in the standard uptake value (SUV) of the lung lesions. Only 3/8 patients remained on 80 units RCI for full 24 weeks. There was no significant difference in the response to therapy for those treated with 40- versus 80-unit RCI., Conclusions: Repository corticotropin treatment was prednisone-sparing and associated with significant improvement in DLCO, PET scan, and patient-reported outcome measures. A dose of 40-unit RCI twice a week was as effective as 80-unit RCI and was better tolerated.

Adrenocorticotropic hormone (ACTH) as a treatment for proteinuria due to nephrotic syndrome (NS) has re-emerged over the last decade. Current clinical data are primarily limited to adults with treatment-resistant NS. Largely unknown to today's clinicians is the existence of early clinical studies, following ACTH's introduction in the late 1940s, showing sustained proteinuria response in idiopathic NS in predominantly pediatric, treatment-naïve patients. Before ACTH, patients suffered severe edema and high mortality rates with no reliable or safe treatment. ACTH dramatically altered NS management, initially through recognition of diuresis effects and then through sustained proteinuria remission. This review synthesizes early clinical literature to inform current NS patient management. We undertook a MEDLINE search using MeSH terms "adrenocorticotropic hormone" and "nephrotic syndrome," with limits 1945-1965 and English. Sixty papers totaling 1137 patients were found; 14 studies (9 short-term, five long-term, N = 419 patients) met inclusion criteria. Studies were divided into two groups: short-term (≤28 days) and long-term (>5 weeks; short-term initial daily treatment followed by long-term intermittent)ACTH therapy and results were aggregated. An initial response, defined as a diuresis, occurred in 74 % of patients/treatment courses across nine short-term ACTH studies. Analyzed in eight of these studies, proteinuria response occurred in 56 % of patients/treatment courses. Across five long-term ACTH studies, proteinuria response was shown in 71 % of patients and was sustained up to 4.7 years following treatment. The inventory and re-evaluation of early clinical data broadens the evidence base of clinical experiences with ACTH for implementation of current treatment strategies and aiding the design of future studies.

Background: Gout is a common type of inflammatory arthritis in patients seen by primary care physicians., Purpose: To review evidence about treatment of acute gout attacks, management of hyperuricemia to prevent attacks, and discontinuation of medications for chronic gout in adults., Data Sources: Multiple electronic databases from January 2010 to March 2016, reference mining, and pharmaceutical manufacturers., Study Selection: Studies of drugs approved by the U.S. Food and Drug Administration and commonly prescribed by primary care physicians, randomized trials for effectiveness, and trials and observational studies for adverse events., Data Extraction: Data extraction was performed by one reviewer and checked by a second reviewer. Study quality was assessed by 2 independent reviewers. Strength-of-evidence assessment was done by group discussion., Data Synthesis: High-strength evidence from 28 trials (only 3 of which were placebo-controlled) shows that colchicine, nonsteroidal anti-inflammatory drugs (NSAIDs), and corticosteroids reduce pain in patients with acute gout. Moderate-strength evidence suggests that low-dose colchicine is as effective as high-dose colchicine and causes fewer gastrointestinal adverse events. Moderate-strength evidence suggests that urate-lowering therapy (allopurinol or febuxostat) reduces long-term risk for acute gout attacks after 1 year or more. High-strength evidence shows that prophylaxis with daily colchicine or NSAIDs reduces the risk for acute gout attacks by at least half in patients starting urate-lowering therapy, and moderate-strength evidence indicates that duration of prophylaxis should be longer than 8 weeks. Although lower urate levels reduce risk for recurrent acute attacks, treatment to a specific target level has not been tested., Limitation: Few studies of acute gout treatments, no placebo-controlled trials of management of hyperuricemia lasting longer than 6 months, and few studies in primary care populations., Conclusion: Colchicine, NSAIDs, and corticosteroids relieve pain in adults with acute gout. Urate-lowering therapy decreases serum urate levels and reduces risk for acute gout attacks., Primary Funding Source: Agency for Healthcare Research and Quality.

Description: The American College of Physicians (ACP) developed this guideline to present the evidence and provide clinical recommendations on the management of gout., Methods: Using the ACP grading system, the committee based these recommendations on a systematic review of randomized, controlled trials; systematic reviews; and large observational studies published between January 2010 and March 2016. Clinical outcomes evaluated included pain, joint swelling and tenderness, activities of daily living, patient global assessment, recurrence, intermediate outcomes of serum urate levels, and harms., Target Audience and Patient Population: The target audience for this guideline includes all clinicians, and the target patient population includes adults with acute or recurrent gout., Recommendation 1: ACP recommends that clinicians choose corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), or colchicine to treat patients with acute gout. (Grade: strong recommendation, high-quality evidence)., Recommendation 2: ACP recommends that clinicians use low-dose colchicine when using colchicine to treat acute gout. (Grade: strong recommendation, moderate-quality evidence)., Recommendation 3: ACP recommends against initiating long-term urate-lowering therapy in most patients after a first gout attack or in patients with infrequent attacks. (Grade: strong recommendation, moderate-quality evidence)., Recommendation 4: ACP recommends that clinicians discuss benefits, harms, costs, and individual preferences with patients before initiating urate-lowering therapy, including concomitant prophylaxis, in patients with recurrent gout attacks. (Grade: strong recommendation, moderate-quality evidence).

There is insufficient evidence to recommend a specific protocol for treatment of infantile spasms (IS) and a lack of standardization among, and even within, institutions. Twice-daily dosing (for the first two weeks) of high-dose natural ACTH for IS is used by many centers and recommended by the National Infantile Spasms Consortium (NISC). Conversely, it is our practice to use once-daily dosing of high-dose natural ACTH for IS. In order to determine the effectiveness of our center's practice, we retrospectively reviewed 57 cases over the past four years at Boston Children's Hospital (BCH). We found that 70% of infants were spasm-free at 14days from ACTH initiation and 54% continued to be spasm-free at 3-month follow-up. Electroencephalogram showed resolution of hypsarrhythmia (when present on the pretreatment EEG) in all responders. Additionally, once-daily dosing of ACTH was well tolerated. We performed a meta-analysis to compare our results against the reports of published literature using twice-daily high-dose ACTH for treatment of IS. The meta-analysis revealed that our results were comparable to previously published outcomes using twice-daily ACTH administration for IS treatment. Our experience shows that once-daily dosing of ACTH is effective for treatment of IS. If larger prospective trials can confirm our findings, it would obviate the need for additional painful injections, simplify the schedule, and support a universal standardized protocol., (Copyright © 2016 Elsevier Inc.

Objective: We evaluated the effectiveness of synthetic adrenocorticotropic hormone (ACTH) therapy without tapering in treating patients with West syndrome., Methods: Forty-four patients with cryptogenic (n = 7) or symptomatic (n = 37) West syndrome were treated with synthetic ACTH therapy between 2003 and 2012. The synthetic ACTH dosage was 0.0125 mg/kg/day administered daily for 2 weeks and then stopped without a tapering period. The initial effectiveness, long-term seizure outcome, and adverse effects were examined., Results: During synthetic ACTH therapy, epileptic spasms disappeared in 37 of 44 patients (84.1%) and hypsarrhythmia on electroencephalography disappeared in 42 of 44 patients (95.5%). The average number of synthetic ACTH injections needed to achieve spasm control in these 37 patients was 5.8. Long-term seizure outcomes were assessed in 31 patients followed up for longer than half a year after synthetic ACTH therapy. Nine (29.0%) of these patients experienced recurrence of epileptic spasms, with a mean interval to recurrence of 2.4 months. Overall, 12 patients (38.7%) experienced various types of seizures other than spasms with a mean interval to recurrence of 8.0 months. Although adverse effects such as hypertension, infection, and mild brain shrinkage were noted in 13 patients (29.5%), no severe adverse effects were observed., Conclusions: These results are comparable to those of other reports on the initial effectiveness and long-term seizure control following synthetic ACTH therapy, and suggest that administration without tapering is reasonable to treat patients with West syndrome.

Repository corticotropin injection (porcine adrenocorticotropic hormone [ACTH] analog) and intravenous methylprednisolone (IVMP) are used to treat inflammatory conditions such as multiple sclerosis (MS) exacerbations and rheumatoid arthritis. This multiple-dose, randomized, crossover, open-label study evaluated and compared pharmacodynamic outcomes in subjects who received ACTH analog (80 U subcutaneously) or IVMP (1 g) daily for 5 days. Specific outcome measures included IVMP and cortisol concentrations, total cortisol-equivalent exposure, immune cell population changes, and tolerability. IVMP and ACTH analog increased granulocyte numbers and decreased lymphocyte counts; effects on both were significantly less pronounced with ACTH analog. Based on total cortisol-equivalent exposure (assuming linearity), administration of 80 U of ACTH analog equates to 30 mg IVMP. Because IVMP doses significantly higher than 30 mg are usually required to treat MS exacerbations, the lower cortisol-equivalent exposure of 80 U ACTH analog supports the hypothesis that efficacy of ACTH analog results from both steroid-dependent and -independent properties. Adverse events were mild in severity; subject incidence for adverse-event reporting was similar following both regimens. The clinical relevance of these findings in autoimmune disease populations is unknown and requires further evaluation., (© 2015 The Authors.

Objective: A single-center, single-blind, parallel-group, randomized clinical trial was performed to test the null hypothesis that adrenocorticotropic hormone is not superior to high-dose prednisolone for treatment of newly diagnosed West syndrome., Methods: Newly diagnosed infants with West syndrome were randomized to receive 14 days of oral prednisolone (40-60 mg/day) or a synthetically prepared intramuscular long-acting adrenocorticotropic hormone (40-60 IU/every other day [0.5-0.75 mg]) according to the United Kingdom Infantile Spasm Study protocol. They were blindly evaluated for infantile spasm remission by day 14, electroclinical remission (spasm cessation + resolution of hypsarrhythmia on a 30-minute electroencephalograph) by day 14 and continued spasm freedom for 28 days., Results: Ninety-seven patients were enrolled in the study, with 48 of them receiving prednisolone and 49 receiving ACTH. There was no significant difference in the baseline characteristics or risk factors for the two treatment groups. By day 14, cessation of infantile spasms occurred in 28/48 (58.3%) infants on prednisolone compared with only 18/49 (36.7%) infants given adrenocorticotropic hormone (P = 0.03) and electroclinical remission in 21 on prednisolone compared with nine on adrenocorticotropic hormone (P = 0.007). Sustained spasm control for 28 consecutive days following electroclinical remission occurred in 15 children on prednisolone compared with six on adrenocorticotropic hormone (P = 0.008). The total number of days required for spasm cessation was significantly less in those treated with prednisolone (3.85 days ± 2.4) compared with adrenocorticotropic hormone (8.65 days ± 3.7) (P = 0.001). Among patients who did not achieve remission, there was a non-significant trend toward greater quantitative reduction of spasms with prednisolone than with adrenocorticotropic hormone (P = 0.079)., Conclusion: Synthetic adrenocorticotropic hormone of 40-60 IU/every other day did not yield superior rates of electroencephalographic or clinical remission when compared with prednisolone of 40-60 mg/day. Significantly, more patients achieved electroclinical remission when treated with prednisolone than with adrenocorticotropic hormone., (Copyright © 2015 Elsevier Inc. All rights reserved.)

Introduction: In the chronic phase of Hemiconvulsion-Hemiplegia-Epilepsy (HHE) syndrome, developing epilepsy may be intractable. Herein, we report a case where adrenocorticotropic hormone (ACTH) ceased an intractable habitual partial seizure in a patient with HHE syndrome., Case Report: A developmentally normal one-year-old girl presented with left focal motor status epilepticus in the clinical course of rotavirus infection. She was diagnosed with HH syndrome. At 4 months after status epilepticus, she developed partial seizures that occurred daily, and which resulted in a stooped posture, head rotation to the right, and contraction of both upper limbs predominantly in the left arm. At this time, she was diagnosed with idiopathic HHE syndrome. Her seizures were not reduced by sodium valproate, clonazepam, clobazam, zonisamide, phenytoin, phenobarbital, topiramate, lamotrigine, or liposteroid. At the age of 7, ACTH therapy was performed. On the 10th day of ACTH therapy, the habitual seizure was ceased. However, partial seizures characterized by left arm contraction then developed. Treatment with 350 mg/day lamotrigine prevented this emerging seizure. She has been free of both seizure types for more than one year, with no serious adverse effects of ACTH therapy., Conclusion: We suggest that ACTH therapy may be useful for patients with HHE, although further studies are required., (Copyright © 2014 The Japanese Society of Child Neurology.

Successful fertilization is essential for reproduction and might be negatively affected by stressful events, which could alter the environment where fertilization occurs. The aim of the study was to determine whether an altered hormonal profile in blood plasma caused by adrenocorticotropic hormone (ACTH) administration could affect in vitro fertilization in the pig model. In experiment 1, gametes were exposed for 24 hours to plasma from ACTH-treated, non-ACTH-treated sows, or medium with BSA. Fertilization, cleavage, and blastocyst rates were lower in the ACTH group compared with the no ACTH or BSA control groups (P < 0.01). In experiment 2, the exposure of matured oocytes for 1 hour before fertilization to the same treatments did not have an impact on their ability to undergo fertilization or on embryo development. In experiment 3, spermatozoa were incubated for 0, 1, 4, and 24 hours under the same conditions. There was no effect of treatment on sperm viability. The percentage of acrosome-reacted spermatozoa remained higher in the ACTH group compared with the non-ACTH-treated group through the incubation period (P < 0.001). Protein tyrosine phosphorylation (PTP) patterns were also affected by treatment (P < 0.001). The presence of an atypical PTP pattern was higher in the ACTH group at all the analyzed time points compared with the BSA and no ACTH groups (P < 0.001). In conclusion, this altered environment may not affect oocyte competence but might affect the sperm fertilizing ability through alterations in the acrosome reaction and correct sequence of PTP patterns., (Copyright © 2015 Elsevier Inc.

The Child Neurology Society/American Academy of Neurology practice parameter has recommended adrenocorticotropic hormone or vigabatrin in the short-term treatment of infantile spasms. When vigabatrin is unavailable or ineffective and adrenocorticotropic hormone is not a treatment option because of the prohibitive cost, other forms of corticosteroids have been considered in the treatment of infantile spasms. This retrospective study reviewed the Hospital for Sick Children's experience with the short-term effectiveness of prednisolone versus adrenocorticotropic hormone in patients with infantile spasms who have failed vigabatrin. The results showed that while adrenocorticotropic hormone was more likely to lead to short-term spasm freedom, there was no difference in the likelihood of longer-term spasm resolution without relapse. These findings can guide clinicians in the treatment of infantile spasms post vigabatrin failure., (© The Author(s) 2014.)

Background: Adrenocorticotropic hormone (ACTH) therapy is the first-line therapy for infantile spasms, and is effective for many other intractable epilepsies. While spasms may respond to ACTH for weeks, a substantial proportion of patients develop recurrent seizures over a yearly period. To maintain efficacy, we treated two children with intractable epilepsy with weekly ACTH therapy for 1 year and described the changes in clinical seizures, electroencephalograms, developmental assessments and side effects., Subjects and Methods: A girl with infantile spasms due to lissencephaly and a boy with atypical absence seizures were studied. In both cases, seizures were frequent and resistant to antiepileptic drugs; electroencephalograms showed continuous epileptiform activities, and the patients' development was delayed and stagnant prior to ACTH treatment. The initial ACTH therapy (daily 0.015 mg/kg for 2 weeks, 0.015 mg/kg every 2 days for 1 week, 0.0075 mg/kg every 2 days for 1 week), was transiently effective in both cases. The second-round ACTH therapy consisted of the initial ACTH therapy protocol followed by weekly ACTH injections (0.015 mg/kg or 0.0075 mg/kg) for 1 year. Both cases were followed for at least 1 year after therapy., Results: In both patients, clinical seizures were completely controlled during and 1 year after the second-round AHCH therapy. Continuous epileptiform discharges disappeared, while intermittent interictal epileptiform discharges remained. Both patients showed some developmental gains after achieving seizure control. No serious side effects were recorded., Conclusion: Further studies are warranted to determine if a long-term weekly ACTH is a safe and effective treatment for intractable epilepsy., (Copyright © 2014 The Japanese Society of Child Neurology.

We report the case of a 7-month-old boy who developed hypofibrinogenemia (66.6 mg/dL; reference value, 170-405 mg/dL) during adrenocorticotropic hormone (ACTH) therapy for infantile spasms. Although the patient showed no clinical signs of a bleeding diathesis, we recommend that plasma fibrinogen levels should be monitored during ACTH therapy, which should be discontinued when fibrinogen levels fall below hemostatic levels (60.0mg/dL) or when bleeding tendencies are recognized., (Copyright © 2014 The Japanese Society of Child Neurology.

We describe an 8-month-old infant with infantile spasms treated with adrenocorticotropic hormone (ACTH) who presented with fatal Legionella pneumophila and Pneumocystis jirovecii infection. Emphasis is placed on the ensuing immunosuppression and infectious sequelae of ACTH therapy. Given that ACTH therapy may increase the risk of fatal infection, patients undergoing such treatment should be closely monitored, with particular attention paid to the functioning of the immune system.

Background: Partial seizures often develop during the clinical course of infantile spasms. Herein, we report a boy with cryptogenic West syndrome, who developed partial seizures that we suspected were induced by the ACTH therapy., Subject: The patient developed cryptogenic West syndrome at six months of age and ACTH therapy was started. On the tenth day of treatment, he developed frequent partial seizures, characterized by being motionless during the seizure with eye deviation to the right. The partial seizures stopped after the ACTH was discontinued, although oral carbamazepine was commenced at the same time. Thus, a definitive role for carbamazepine in the treatment of the partial seizures was unclear as the timing of the seizure cessation also corresponded to the discontinuation of the ACTH therapy. We suspected that the partial seizures were induced by the ACTH therapy for the following reasons: (1) seizures appeared only during ACTH therapy, (2) no new epileptic focus was revealed by EEG, MRI, or (99m)TcECD SPECT, and (3) the seizures were different from the epileptic spasms., Conclusion: Our results suggest that ACTH might induce partial seizures in West syndrome. Further studies are required to confirm this phenomenon., (Copyright © 2013 The Japanese Society of Child Neurology. Published by Elsevier B.V. All rights reserved.)

Background and Objectives: Adrenocorticotropic hormone (ACTH) has shown efficacy as primary and secondary therapy for nephrotic syndrome due to membranous nephropathy. The data on using ACTH to treat idiopathic FSGS are limited. This report describes our experience using ACTH for nephrotic syndrome due to idiopathic FSGS in the United States., Design, Setting, Participants, & Measurements: Twenty-four patients with nephrotic syndrome from idiopathic FSGS were treated with ACTH gel at two academic medical centers between 2009 and 2012, either as part of investigator-initiated pilot studies (n=16) or by prescription for treatment-resistant FSGS (n=8). The primary outcome was remission of proteinuria. The median dose of ACTH was 80 units injected subcutaneously twice weekly. Treatment durations were not uniform., Results: Twenty-two patients had received immunosuppression (mean, 2.2 medications) before ACTH therapy. Six patients had steroid-dependent and 15 had steroid-resistant FSGS. At the time of ACTH initiation, the median serum creatinine (interquartile range) was 2.0 (1.1-2.7) mg/dl, estimated GFR was 36 (28-78) ml/min per 1.73 m(2), and urine protein-to-creatinine ratio was 4595 (2200-8020) mg/g. At the end of ACTH therapy, 7 of 24 patients (29%) experienced remission (n=2 complete remissions, n=5 partial remissions). All remitters had steroid-resistant (n=5) or steroid-dependent (n=2) FSGS. Two responders relapsed during the follow-up period (mean ± SD, 70±31 weeks). Adverse events occurred in 21 of 24 patients, including one episode of new-onset diabetes that resolved after stopping ACTH and two episodes of AKI., Conclusions: Response to ACTH treatment among steroid-resistant or steroid-dependent patients with FSGS is low, but ACTH gel may be a viable treatment option for some patients with resistant nephrotic syndrome due to idiopathic FSGS. Further research is necessary to determine which patients will respond to therapy.

Background: Abiraterone strongly inhibits androgen synthesis but may lead to an increase in mineralocorticoid hormones that may impair its long term tolerability in patients with prostate cancer. How to implement available therapies in the management and prevention of these potential side effects is a matter of current clinical research., Methods: The acute and long term consequences of mineralocorticoid excess and the effects of available treatments have been reviewed. Prospective studies in which abiraterone was employed were identified to assess the frequency and severity of the mineralocorticoid excess syndrome and the efficacy of ameliorating therapeutic approaches., Results: Glucocorticoids to inhibit the ACTH increase that drives mineralocorticoid synthesis and mineralocorticoid receptor (MR) antagonists can be used in the management of the abiraterone-induced mineralocorticoid excess syndrome. Phase I and II trials of abiraterone without additional therapies revealed that mineralocorticoid excess symptoms occur in the majority of patients. Eplerenone, a specific MR antagonist, seems to be effective but it does not control the mineralocorticoid excess. Glucorticoid supplementation to control ACTH drive is therefore needed. In several randomized trials the addition of prednisone (10mg daily) to abiraterone was not able to prevent mineralocorticoid excess syndrome in many cases and thus cannot be considered the gold standard., Conclusion: At present, the best conceivable treatment for managing the abiraterone-induced mineralocorticoid excess consists of the administration of glucocorticoid replacement at the lowest effective dose ± MR antagonists and salt deprivation. The drug doses should be modulated by monitoring blood pressure, fluid retention and potassium levels during therapy., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

Objective: To review the current literature on the efficacy and safety of low- versus high-dose adrenocorticotropic hormone (ACTH) regimens, low-dose ACTH regimens, and comparison of ACTH with oral corticosteroids or vigabatrin for the treatment of West syndrome., Data Sources: A literature search was performed using MEDLINE, PubMed, and Inter national Pharmaceutical Abstracts (1975-November 2012) to identify studies for inclusion. In addition, reference citations from identified publications were reviewed. The following search terms were used: infantile spasms, West syndrome, adrenocorticotropic hormone, corticotropin, symptomatic West syndrome, cryptogenic West syndrome, pediatric, children, infant, adolescent, and neonate., Study Selection and Data Extraction: Studies included in this article evaluated low-dose versus high-dose ACTH, low-dose ACTH, and ACTH compared with vigabatrin and oral corticosteroids. Data reporting the efficacy and adverse effects of ACTH, vigabatrin, and oral corticosteroids were extracted from each publication. Only English-language publications were included. We initially reviewed 20 studies, and 14 were included: 5 prospective randomized clinical trials and 9 chart reviews., Data Synthesis: West syndrome is an age-specific epileptic disorder that occurs in infancy and early childhood. It is characterized by the triad of infantile spasms, neurodevelopmental regression or delay, and hypsarrhythmia on electroencephalogram (EEG). The efficacy and adverse events of ACTH with different dosage regimens were reviewed and analyzed. ACTH compared with vigabatrin and oral corticosteroids was also evaluated. Based on this review, low-dose ACTH is probably as effective as high-dose ACTH. Compared with other agents, ACTH is suggested to be more effective than oral corticosteroids, and compared with vigabatrin, it has improved outcomes in the cessation of spasms. However, studies evaluating the efficacy of ACTH are limited by small sample size, inconsistent dosage regimens, and the use of synthetic or natural ACTH products. Serious adverse events, including intracranial hemorrhage, brain atrophy, Cushing syndrome, infection, weight gain, and hypertension, may deter the use of ACTH. Short-term therapy is recommended to reduce the risk of adverse effects., Conclusions: The current literature suggests that short-term, low-dose ACTH should be considered first-line treatment of infantile spasms.

Objective: We aimed at assessing the efficacy and safety of adrenocorticotropic hormone (ACTH) for the treatment of acute gout in hospitalized patients., Methods: We retrospectively reviewed our inpatient consultation records and identified 181 cases of gout where ACTH was used as first line treatment. The hospital medical records of these patients were fully reviewed. A total of 181 patients were treated with 1mg of synthetic ACTH intramuscularly., Results: A response was seen in 77.90% of patients and was evident the day following ACTH injection. The majority of non-responders (87.50%) were treated once more with ACTH the day following the first injection; 82.85% of these patients responded. A relatively small percentage of responders suffered a second gouty attack (11.34%) at a median of four days from the initial attack. They were retreated with a single ACTH course and all responded. Blood pressure and potassium levels remained stable 24 and 48 hours following ACTH administration. Diabetic patients showed an increase in fasting glucose levels 24 hours following the injection compared to baseline but this increase was not evident at 48 hours., Conclusions: Our data indicate that ACTH is effective and safe for the treatment of gout in hospitalized patients. ACTH is an attractive therapeutic option for hospitalized patients since the use of non-steroidal anti-inflammatory drugs, steroids or colchicine in this patient population may be problematic., (Copyright © 2012 Société française de rhumatologie.
