Purpose: To study the role of Th2-attracting chemokines in opsoclonus-myoclonus syndrome (OMS), a serious neurological paraneoplastic disorder in need of better immunological understanding and therapy., Methods: The CCR4 agonists CCL22 and CCL17 were measured in serum by ELISA in children with OMS (238 and 260, respectively), pediatric controls (115 and 143), and other inflammatory neurological disorders (33 and 24)., Results: Both CCL22 (+55 %) and CCL17 (+121 %) were significantly elevated in untreated OMS compared to controls and inter-correlated (p < 0.0001). Their concentrations in untreated OMS also were higher than in OIND (21 %, 41 %). The concentration of CCL22 in ACTH and steroids groups (not IVIg) was 51 % lower than in controls, but only a smaller effect of ACTH on CCL17 was found. Prospective longitudinal studies revealed a precipitous 81 % drop in CCL22 even by the first week of high-dose ACTH therapy, staying below control mean for at least 12 weeks, and a 34 % reduction after 8 months of combined treatment. Response to ACTH was dose-related (r = -0.50, p < 0.0001). Luminex detection confirmed the ELISA results for CCL22, which were about 200 % higher., Conclusions: These data reveal an elevated serum concentration of Th2-attracting chemokines CCL22 and CCL17 in OMS. Marked and rapid reduction in CCL22, not CCL17, with either ACTH or steroid therapy suggests differential regulation and cellular sources of CCR4 ligands, and CCL22 as a potential candidate biomarker for ACTH or corticosteroid effect.

The α2-isoform of the Na,K-ATPase (α2) is the minor isoform of the Na,K-ATPase expressed in the cardiovascular system and is thought to play a critical role in the regulation of cardiovascular hemodynamics. However, the organ system/cell type expressing α2 that is required for this regulation has not been fully defined. The present study uses a heart-specific knockout of α2 to further define the tissue-specific role of α2 in the regulation of cardiovascular hemodynamics. To accomplish this, we developed a mouse model using the Cre/loxP system to generate a tissue-specific knockout of α2 in the heart using β-myosin heavy chain Cre. We have achieved a 90% knockout of α2 expression in the heart of the knockout mice. Interestingly, the heart-specific knockout mice exhibit normal basal cardiac function and systolic blood pressure, and in addition, these mice develop ACTH-induced hypertension in response to ACTH treatment similar to control mice. Surprisingly, the heart-specific knockout mice display delayed onset of cardiac dysfunction compared with control mice in response to pressure overload induced by transverse aortic constriction; however, the heart-specific knockout mice deteriorated to control levels by 9 wk post-transverse aortic constriction. These results suggest that heart expression of α2 does not play a role in the regulation of basal cardiovascular function or blood pressure; however, heart expression of α2 plays a role in the hypertrophic response to pressure overload. This study further emphasizes that the tissue localization of α2 determines its unique roles in the regulation of cardiovascular function.

Despite proven good efficacy of pneumococcal conjugated vaccine in preventing invasive pneumococcal disease, breakthrough infections remain a noticeable problem with significant morbidity and mortality, especially in selected high-risk groups. We present a 2-year-old girl with infantile spasm, who was treated with antiepileptic drugs and adrenocorticotropic hormone (ACTH). Vaccination with three doses 7-valent pneumococcal conjugate vaccine had been completed one month before ACTH therapy. Two months after ACTH therapy, she suffered from fever, cough, and decreased activity. Streptococcus pneumoniae, serotype 6B, was detected in blood culture. Vaccine failure could be possibly due to ACTH therapy., (Copyright © 2012. Published by Elsevier B.V.)

A 1-year-old male began suffering from West syndrome at 3 months of age, when electroencephalography revealed hypsarrhythmia accompanied by a periodic, brief suppression phase. The administration of adrenocorticotropic hormone was partially effective for stopping the condition, and the seizure type evolved into brief tonic seizures at 6 months. Thereafter, progressive atrophy of the brain became evident by 9 months of age, predominantly at the brainstem and cerebellum. Severe hypomyelination of the cerebral white matter was revealed at the age of 1 year, and a de novo heterozygous mutation in the SPTAN1 gene was confirmed. The patient showed severely impaired psychomotor development, and had gained no visual attention. These findings contribute to the characterization of this recently established entity and facilitate the identification of further patients., (Copyright © 2012 The Japanese Society of Child Neurology.

The therapeutic benefits of adrenocorticotropic hormone in multiple sclerosis are usually ascribed to its corticotropic actions. Evidence is presented that adrenocorticotropic hormone, approved for multiple sclerosis relapses, acts via corticosteroid-independent melanocortin pathways to engender down-modulating actions on immune-system cells and the cytokines they synthesize. Immune response-dampening effects are also brought about by agent-induced neurotransmitters that inhibit immunocytes. The likelihood that adrenocorticotropic hormone promotes microglial quiescence and counteracts glucocorticoid-mediated bone resorption is discussed.

Background and Objective: Adrenocorticotropic hormone (ACTH) is able to reduce proteinuria in nondiabetic glomerulopathies through activation of melanocortin receptors (MCR) expressed in the podocyte. To determine the efficacy of ACTH, we conducted a randomized, open-label pilot trial of ACTH gel in patients with advanced diabetic nephropathy., Study Design: Twenty-three (23) patients with diabetic nephropathy were randomized to daily subcutaneous (SQ) injections of 16 or 32 units of ACTH gel for six months. Outcome. The primary endpoint was the percentage of patients achieving a complete remission (<300 mg/24 hours) within 6 months. Exploratory endpoints included the percentage of partial (50% reduction) remissions, changes in Cr, and urinary cytokine markers., Results: After 6 months of ACTH gel therapy, 8 of 14 (57%) patients achieved a complete (n = 1) or partial (n = 7) remission. In the low-dose ACTH gel group (16 units), urinary protein fell from 6709 + 953 to 2224 + 489 mg/24 hrs (P < 0.001). In contrast, 2 of 6 patients in the 32-unit group achieved partial remission, but aggregate proteinuria (5324 + 751 to 5154 + 853 mg/24 hours) did not change. Urinary VEGF increased from 388 to 1346 pg/mg urinary creatinine (P < 0.02) in the low-dose group but remained unchanged in the high-dose group., Conclusion: ACTH gel stabilizes renal function and reduces urinary protein for up to 6 months after treatment. The ClinTrials.gov identifier is NCT01028287.

Background: Approximately 50% of people with myasthenia gravis present with purely ocular symptoms, so called ocular myasthenia. Of these between 50% to 60% develop generalized disease, most within two years. Their management is controversial. This is an update of a review first published in 2006 and previously updated in 2008 and 2010., Objectives: To assess the effects of treatments for ocular myasthenia and to answer three specific questions. Are there any treatments that impact the progression from ocular to generalized disease? Are there any treatments that improve symptoms of diplopia or ptosis? What is the frequency of adverse effects associated with treatments used?, Search Methods: In this updated review, we searched the Cochrane Neuromuscular Disease Group Specialized Register (3 August 2012), CENTRAL (2012, Issue 7), MEDLINE (January 1996 to July 2012) and EMBASE (January 1974 to July 2012) for randomized controlled trials (RCTs) as well as case-control and cohort studies. The titles and abstracts of all articles were read by both authors and the full texts of possibly relevant articles were reviewed. The references of all manuscripts included in the review were scanned to identify additional articles of relevance and experts in the field were contacted to identify additional published and unpublished data. Where necessary, we contacted authors for further information., Selection Criteria: Inclusion required meeting three criteria: (a) randomized (or quasi-randomized) controlled study design; (b) active treatment compared to placebo, no treatment or some other treatment; and (c) results reported separately for patients with ocular myasthenia (grade 1) as defined by the Myasthenia Gravis Foundation of America., Data Collection and Analysis: We collected data regarding the risk of progression to generalized myasthenia gravis, improvement in ocular symptoms, and the frequency of treatment-related side effects., Main Results: In the original review, we identified two RCTs relevant to the treatment of ocular myasthenia, only one of which reported results in terms of the pre-specified outcome measures used in this review. This study included only three participants and was of limited methodological quality. There were no new RCTs in searches conducted for this or previous updates. In the absence of data from RCTs, we present a review of the available observational data., Authors' Conclusions: The available randomized controlled literature does not permit any meaningful conclusions about the efficacy of any form of treatment for ocular myasthenia. Data from several reasonably good quality observational studies suggest that corticosteroids and azathioprine may be beneficial in reducing the risk of progression to generalized myasthenia gravis.

The aim of the study was to determine if early steroid treatment of infantile spasms is associated with ocular complications years after its termination. Twenty-five patients with infantile spasms who underwent prolonged treatment with intramuscular synthetic adrenocorticotropic hormone (ACTH) and oral prednisone were evaluated for ocular complications 2 to 33 years after treatment cessation. Patients were followed by an ophthalmic examination that included anterior and posterior segments and measurement of intraocular pressure. Intraocular pressure was normal bilaterally in all patients. Findings on anterior segment examination were unremarkable. On posterior segment examination, 3 patients had an increased cup/disc ratio with normal intraocular pressure. In 2 patients, the increased ratio was considered an anatomical variant. Posterior segment findings in 2 patients were attributed to their background disease. In conclusion, early treatment with high-dose synthetic adrenocorticotropic hormone and oral prednisone for infantile spasm is apparently not associated with a risk of occular complications on long-term follow-up.

Background: To evaluate the concept of critical illness-related corticosteroid insufficiency (CIRCI) by studying the clinical significance, in terms of risk factors and outcome, of changes in the cortisol response to repeated adrenocorticotropic hormone (ACTH) testing in the course of critical illness., Patients and Methods: In a retrospective study in a medical-surgical intensive care unit (ICU) of a university hospital, we retrospectively included 54 consecutive patients during a 3-year period, who underwent 2 conventional 250 μg ACTH tests at an interval >24 hours, because of ≥6 hours hypotension requiring repeated fluid challenges or vasopressor/inotropic treatment, while corticosteroid treatment was not (yet) initiated. Serum cortisol was measured immediately before and 30 and 60 minutes after intravenous injection of 250 μg of ACTH. Patients were divided into those with an increase (≥0, n = 27) or a decrease (n = 27) in time in delta (Δ) cortisol in response to ACTH and with a Δcortisol <100 (n = 11) and ≥100 nmol/L (n = 43) at the second ACTH test., Results: Changes in Δcortisol in time were paralleled by changes in Δcortisol/albumin, with a higher frequency of septic shock, persistently high disease severity, increased renal replacement therapy, and decreased platelet counts in the course of disease with a decrease in Δcortisol in time. Similar trends in increased disease severity were observed when Δcortisol remained or fell to <100 nmol/L. A decrease in Δcortisol between the 2 tests, particularly to <100 nmol/L, was associated with increased mortality (18 nonsurvivors in the ICU)., Conclusions: The findings favor the concept of dynamic adrenal function rather than poor reproducibility of the ACTH test, so that development of CIRCI, particularly in complicated septic shock and indicated by a fall in Δcortisol (to <100 nmol/L) upon ACTH, correlates to a poor prognosis, independently of baseline cortisol, cortisol binding in blood, and disease severity.

Objective: We have shown that oral corticotropin hormone (ACTH) decreased clinical score, inflammatory foci and T(eff) IL-17 in fed and adoptive transferred recipient mice with experimental autoimmune encephalomyelitis (EAE). Therefore, we determined whether oral administration of ACTH had immunological and endocrinological effects and was safe in humans., Methods: Three groups of three healthy adult volunteers were assayed for total serum ACTH, cortisol and a set of pro-inflammatory and counter-regulatory cytokines after ingested dose(s) of ACTH 4 IU (n=3), 41 IU (n=3), or 123 IU (n=3) over 5 days., Results: There were no safety issues during the trial. There was no increase in total ACTH levels after day 1 or day 5. There was no significant increase in total cortisol among the groups comparing day 1 to day 5. There were significant decreases in the inflammatory cytokine IL-1 and IL-17 secretion at day 6 compared to baseline with the 123 IU dose but not after the 4 IU and 41 IU doses., Conclusions: These data provide evidence for the safety and an immunological effect of oral ACTH in humans. It is unknown if the change in IL-1 and IL-17 reflects a local GI-mediated effect or effects following systemic absorption of ACTH., (© 2012 Elsevier Masson SAS. All rights reserved.)

We previously reported that adrenocorticotropic hormone (ACTH)-treated rats serve as a valuable animal model for tricyclic antidepressant-resistant depressive conditions. The present study was undertaken to investigate the changes in neurogenesis in the hippocampus of ACTH-treated rats. Chronic treatment of ACTH decreased the number of bromodeoxyuridine-labeled cells in the dentate gyrus, and the coadministration of imipramine and lithium, and electroconvulsive stimuli recovered these reductions. Furthermore, chronic ACTH treatment also decreased the expression of brain-derived neurotrophic factor, and the coadministration of imipramine and lithium, and electroconvulsive stimuli recovered these reductions. These results suggest that antidepressant-resistant depression is caused by the suppression of neurogenesis, and the coadministration of imipramine and lithium, and electroconvulsive stimuli exert an antidepressant-like effect by recovering proliferative signals and neurogenesis.

Background: Effective and tolerable treatment options for patients with dermatomyositis and polymyositis are limited. This retrospective case review describes treatment with adrenocorticotropic hormone (ACTH) gel in five patients who experienced a disease exacerbation and either failed or were unable to tolerate the side effects of previous therapy with steroids, intravenous immunoglobulins, and steroid-sparing drugs., Methods: Patients received ACTH gel subcutaneous injections of 80 U (1 mL) twice weekly (four patients) or once weekly (one patient) over the course of 12 weeks for short-term treatment of symptom exacerbations. Manual muscle testing using the Medical Research Council scale was assessed at baseline and at 3 months., Results: Improvement was seen in all patients, including improved muscle strength, decreased pain, and resolution of skin involvement. All patients tolerated the treatment well, and no significant side effects occurred., Conclusion: The treatment of dermatomyositis and polymyositis is an approved use for ACTH gel, and these anecdotal reports would suggest consideration of ACTH gel as a therapeutic option. Further investigation is warranted.

West syndrome is a rare epileptic disease of infancy, typified by an association of characteristic spasms, hypsarrhythmia on electroencephalography and severe psychomotor retardation or deterioration. Adrenocorticotropic hormone (ACTH) is the current first-line therapy for West syndrome despite the fact that ACTH therapy is associated with various adverse effects. We describe a rare case of iatrogenic diabetes mellitus during ACTH therapy in a patient with symptomatic West syndrome. The infant had cushingoid facies, hirsutism and biochemical evidence of diabetes due to excessive glucocorticoid production with hyperplasia of both adrenal glands at ultrasound examination, without mineralocorticoid excess; in addition, he presented also short-term weight gain, marked electrolyte disturbances, hypokalemic alkalosis and infections. When ACTH is used to treat patients with West syndrome, it is necessary to follow glycemic levels until to the end of therapy.

Purpose: A synthetic adrenocorticotropin (ACTH) analog has shown efficacy in Europe as primary and secondary therapy for nephrotic syndrome, but there is no published experience using the natural, highly purified ACTH gel formulation, available in the United States, for nephrotic syndrome. We therefore investigated the use of ACTH gel for nephrotic syndrome in the United States., Patients and Methods: Twenty-one patients with nephrotic syndrome treated with ACTH gel outside of research settings in the United States, with initiation of therapy by December 31, 2009, allowing a minimum 6 months follow-up. We defined complete remission as stable renal function with proteinuria falling to <500 mg/day, and partial remission as stable renal function with >50% reduction in proteinuria from 500 to 3500 mg/day., Results: Twenty-one patients with nephrotic syndrome were treated: 11 with idiopathic membranous nephropathy (iMN), 4 with membranoproliferative glomerulonephritis (MPGN), 1 with focal segmental glomerulosclerosis (FSGS), 1 with minimal change disease (MCD), 1 with immunoglobulin A (IgA) nephropathy, 1 with class V systemic lupus erythematosus (SLE) glomerulonephritis, 1 with monoclonal diffuse proliferative glomerulonephritis, and 1 with unbiopsied nephrotic syndrome. ACTH was used as primary therapy for 3 patients; the remaining patients had previously failed a mean 2.3 immunosuppressive regimens. Eleven patients achieved a complete or partial remission, with 4 (19%) in complete remission. Of the 11 patients who achieved remission, 9 had iMN, 1 had FSGS, and 1 had IgA nephropathy. Of the 11 patients with iMN, 3 (27%) achieved complete remission and 6 (55%) achieved partial remission despite having previously failed a mean 2.4 therapies. Five patients reported steroid-like adverse effects, but there were no severe infections. The limitations were retrospective data analysis with short-term follow-up., Conclusion: ACTH gel may be a viable treatment option for resistant nephrotic syndrome due to membranous nephropathy. Short-term data suggest that remission rates may approach 80%.

Purpose: A prospective study was conducted for the purpose of identifying the efficacy and safety of a protocol, first-line topiramate (TPM) followed by low-dose adrenocorticotropic hormone (ACTH) as the second drug, in the treatment of infantile spasms., Methods: 40 children newly diagnosed with infantile spasms between 2007 and 2008 were enrolled in this study. They received an initial dose of 0.5-1mg/kg/day TPM, with 0.5-1mg/kg/day ascending every 3-7 days up to the target dose within the first 1 month. Partial/nonresponders for TPM were subsequently added low-dose and short-duration ACTH as the second treatment. Both efficiency and side effects were evaluated during the follow-up period., Results: Infants became spasms-free in 27 (67.5%) of all patients comprising 10 patients treated with TPM monotherapy and 17 with the combination of TPM and ACTH. Greater than 75% reduction in the frequency of spasms was found in 4 of all patients and at least 50% reduction in 4 patents as well. Side effects occurred in 29 (72.5%) patients; apart from 6 patients who needed moderately medical intervention, side effects throughout the trial were mild and well tolerated., Conclusions: This prospective study demonstrated that, on the basis of primary TPM therapy, the combination treatment both TPM and low-dose ACTH was effective and available for the patients with infantile spasms., (Copyright © 2010 Elsevier B.V.

Background: Despite over 50 years of experience with adrenocorticotropic hormone (ACTH) as a treatment for acute exacerbations of multiple sclerosis, there have been no trials examining the options of the 2-3-week dosing regimen or intramuscular injection protocol used in the original trials. At our clinic, we performed a small, prospective, randomized pilot study to examine the efficacy and safety of, and patient satisfaction with, a short (five-day) self-administered ACTH dosing protocol for exacerbations of multiple sclerosis, and to compare the subcutaneous and intramuscular routes of administration., Methods: Patients for this study were recruited from an outpatient treatment clinic. Each patient self-administered natural ACTH gel 80 U/day by subcutaneous or intramuscular injection for five consecutive days and was evaluated at baseline and on days 7 and 14. Patient feedback was collected using the Patient Global Impression of Change (PGI-C, the primary efficacy measure), a patient global visual analog scale, the Expanded Disability Status Scale, a timed walk, the Nine-hole Peg Test, and the Clinical Global Impression of Change., Results: Of the 20 enrolled patients (mean age 39.5 years), 19 completed the study. On day 14, 61.1% of patients (11 of 18 with day 14 scores) were treatment responders, and rated their condition as "very much improved" or "much improved" on the PGI-C. The intramuscular group had numerically more responders, but there was no significant difference in the proportion of responders between the intramuscular and subcutaneous groups at day 14 (P = 0.3). The intramuscular route of injection was associated with more injection site pain than the subcutaneous route., Conclusion: A shorter five-day course of intramuscular or subcutaneous ACTH gel may improve symptoms associated with acute exacerbations of multiple sclerosis. Larger studies with standard of care controls are needed to confirm whether this shorter course of intramuscular or subcutaneous ACTH gel is effective and could potentially be substituted for the standard 14-day treatment.

Many patients with gout have comorbidities, including hypertension and chronic kidney disease (CKD). The goals when treating gout are no different in these patients, but the choice and dosage of drugs may need to be modified.

Posterior subcapsular cataract is a well-known complication of corticosteroid treatment. While this association has not been established for adrenocorticotropic hormone (ACTH) treatment, similar side effects would be expected for the 2 drugs given the mechanism of ACTH, which stimulates glucocorticoid synthesis and secretion. The authors report 2 children who were treated with ACTH for infantile spasms who developed bilateral posterior subcapsular cataracts. The authors recommend that children treated with ACTH be referred promptly to a pediatric ophthalmologist as these young, often developmentally delayed children may not exhibit recognizable signs of visual loss. Prompt evaluation and treatment of cataracts in children is important to prevent permanent vision loss from deprivation amblyopia.

Background: Glucocorticoid-induced hypertension is associated with imbalance between nitric oxide (NO) and superoxide. One of the pathways that causes this imbalance is endothelial NO synthase (eNOS) uncoupling. In the present study, adrenocorticotrophic hormone (ACTH)- and dexamethasone-treated rats were further treated with sepiapterin, a precursor of tetrahydrobiopterin, or N-nitro-L-arginine (NOLA), an inhibitor of NOS, to investigate the role of eNOS uncoupling in glucocorticoid-induced hypertension., Methods: Male Sprague-Dawley (SD) rats (n = 7-13/group) were treated with either sepiapterin (5 mg/kg/day, IP) or saline (sham) 4 days before and during ACTH (0.2 mg/kg/day, SC), dexamethasone (0.03 mg/kg/day, SC), or saline treatment. NOLA (0.4 mg/ml in drinking water) was given to rats 4 days before and during dexamethasone treatment. Systolic blood pressure (SBP) was measured by the tail-cuff method., Results: Both ACTH (116 +/- 2 to 135 +/- 3 mm Hg (mean +/- s.e.m.), P < 0.001) and dexamethasone (114 +/- 4 to 133 +/- 3 mm Hg, P < 0.0005) increased SBP. Sepiapterin alone did not alter SBP. Sepiapterin did not prevent ACTH- (129 +/- 4 mm Hg, NS) or dexamethasone-induced hypertension (135 +/- 3 mm Hg, NS), although plasma total biopterin concentrations were increased. NOLA increased SBP in rats prior to dexamethasone or saline treatment. NOLA further increased SBP in both saline- (133 +/- 4 to 157 +/- 3 mm Hg, P < 0.05) and dexamethasone-treated rats (135 +/- 5 to 170 +/- 6 mm Hg, P < 0.05). ACTH and dexamethasone increased plasma F(2)-isoprostane concentrations. Neither sepiapterin nor NOLA significantly affected this marker of oxidative stress., Conclusion: Sepiapterin did not prevent ACTH- or dexamethasone-induced hypertension. NOLA exacerbated dexamethasone-induced hypertension. These data suggest that eNOS uncoupling does not play a major role in the genesis of glucocorticoid-induced hypertension in the rat.

Background: Infantile spasms (IS) is an age-specific and severe epileptic encephalopathy that occurs in infancy and early childhood and is usually refractory to conventional antiepileptic drugs. Adrenocorticotropic hormone (ACTH) has been the treatment of choice for IS, but ACTH use has been associated with infection and hypertension. Magnesium ion is an N-methyl-D-aspartic acid (NMDA)-noncompetitive antagonist that might inhibit NMDA activity and has antiepileptic and neuroprotective effects., Objective: This study compared the efficacy and tolerability of ACTH + magnesium sulfate (MgSO(4)) versus ACTH monotherapy for the treatment of IS., Methods: This 24-week, randomized, open-label follow-up study enrolled male and female infants with IS. Patients were randomly assigned to receive ACTH 25 U/d + MgSO(4) 0.25 g/kg/d, or ACTH 25 U/d only (control), intravenously for 3 weeks. Efficacy was assessed over a period of 24 weeks based on seizure frequency, EEG, and Gesell testing of psychomotor skills (subscales: language, motor, adaptive, and personal-social skills; measured using a developmental quotient [DQ] ). Tolerability was assessed by monitoring for adverse events using laboratory analysis and clinical evaluation., Results: Thirty-eight infants were enrolled (23 male, 15 female; median age, 9.2 months; 19 patients per group). At 12 weeks, 14 patients (73.7%) who received ACTH + MgSO(4) and 9 patients (47.4%) in the control group were seizure free. At 24 weeks, seizure-free rates were 12 (63.2%) in the ACTH + MgSO(4) group and 10 (52.6%) in the control group. On EEG, 9 patients (47.4%) in the ACTH + MgSO(4) group achieved complete recovery (normalized EEG), 5 (26.3 %) attained partial improvement (multifocal spike wave), and 5 (26.3%) had no improvement (hypsarrhythmia or modified hypsarrhythmia). At 4 weeks, in the control group, 5 patients (26.3 %) achieved complete recovery, 6 (31.6%) achieved partial improvement, and 8 (42.1%) had no improvement. Of the 12 patients who were seizure free at 24 weeks in the ACTH + MgSO(4) group, 11 (91.7%) had complete recovery (normalized EEG); this rate was 7 of 10 (70.0%) in the control group. In the ACTH + MgSO(4) group, the change from baseline to 24 weeks in mean (SD) personal-social DQ was significant (from 48.6 [6.4] to 65.2 [7.1], respectively; P < 0.05). In the control group, the difference before and after treatment was nonsignificant (47.7 [6.0] vs 49.9 [4.4]). None of the other Gesell test findings were significant versus baseline. The most common AEs included upper respiratory tract infection and pyrexia (both, 3 [15.8%] per group); diarrhea (2 [10.5%] per group); and hypertension, insomnia, and irritability (all, 0 in the ACTH + MgSO(4) group and 2 [10.5%] in the control group). None of the between-group differences in the prevalences of AEs were significant between the 2 groups., Conclusions: In this study in infants with IS, the proportions of patients who were seizure free from 4 to 24 weeks were significantly greater in the ACTH + MgSO(4) group compared with the ACTH monotherapy group. Personal-social neurodevelopment was significantly improved from baseline in the group that received combination treatment. Both treatments were generally well tolerated.

Twelve immunotherapy-naïve children with opsoclonus-myoclonus syndrome and CSF B cell expansion received rituximab, adrenocorticotropic hormone (ACTH), and IVIg. Motor severity lessened 73% by 6 mo and 81% at 1 yr (P < 0.0001). Opsoclonus and action myoclonus disappeared rapidly, whereas gait ataxia and some other motor components improved more slowly. ACTH dose was tapered by 87%. Reduction in total CSF B cells was profound at 6 mo (-93%). By study end, peripheral B cells returned to 53% of baseline and serum IgM levels to 63%. Overall clinical response trailed peripheral B cell and IgM depletion, but improvement continued after their levels recovered. All but one non-ambulatory subject became ambulatory without additional chemotherapy; two relapsed and remitted; four had rituximab-related or possibly related adverse events; and two had low-titer human anti-chimeric antibody. Combination of rituximab with conventional agents as initial therapy was effective and safe. A controlled trial with long-term safety monitoring is indicated., ((c) 2009 Movement Disorder Society.)

For treatment of intractable epilepsies, there are no data comparing conventional adrenocorticotropic hormone and pulsatile corticoid therapy with dexamethasone. A retrospective comparison of efficacy was therefore conducted for both forms of application. Between 1989 and 2001, a series of 11 children with West syndrome and 3 with Lennox-Gastaut syndrome were treated with adrenocorticotropic hormone (group 1); between 2003 and 2006, 7 children with West syndrome, 5 with electrical status epilepticus during slow sleep, and 2 with Lennox-Gastaut syndrome were treated with pulsatile corticoid therapy (group 2). In group 1 (n = 14), 9/11 West syndrome patients became seizure free, but none with Lennox-Gastaut syndrome (0/3). In group 2 (n = 14), 4/7 West syndrome patients became seizure-free, 1/2 with Lennox-Gastaut syndrome exhibited seizure-frequency reduction, and 2/5 patients with electrical status epilepticus during slow-wave sleep exhibited significant improvement according to electroencephalograms. In West syndrome, pulsatile corticoid therapy was an effective alternative treatment to adrenocorticotropic hormone, whereas in Lennox-Gastaut syndrome in general steroids did not lead to a significant seizure reduction. In electrical status epilepticus during slow-wave sleep, treatment with pulsatile corticoid therapy seems to be effective and should be investigated in a larger group of patients.

Objective: The efficacy and adverse effects of conventional dose and low dose adrenocorticotrophic hormone (ACTH) therapy for West syndrome (WS) were compared in order to identify a low effective dose with few adverse effects., Methods: A prospective randomized controlled study was conducted. Thirty children with cryptogenic (n=8) or symptomatic (n=22) WS were enrolled. They were randomly assigned to receive either conventional dose or low dose ACTH therapy. For the conventional dose group, ACTH 50 IU per day was administered for 2 weeks and tapered to zero over the subsequent 2 weeks. For the low dose group, 0.4 IU/kg per day was injected for 2 weeks. After seizures were fully controlled, ACTH was tapered to zero over the subsequent 2 weeks. If there was an absence of an effective response in the low dose group, the dosage was increased to 1 IU/kg per day for the next 2 weeks and then tapered to zero over 2 weeks. Both effectiveness and adverse effects were compared between the two groups., Results: There were no significant differences in the good initial responses between the conventional and the low dose groups, which were 53% and 60%, respectively (P> 0.05). EEG findings after ACTH therapy, the rate of relapse of spasms, and the interval to relapse were not different between the two groups (P> 0.05). The long-term outcomes were assessed in the initial 8 responders, and there were no significant differences between the two groups (follow-up duration>12 months). The rates of good efficacy and disappearance of the hypsarrhythmia were significantly higher in the cryptogenic WS group than in the symptomatic WS group (P<0.05). The incidence of ACTH therapy related-adverse effects in the conventional dose group (93%) was significantly higher than in the low dose group (20%) (P<0.01). The mild brain shrinkage was observed in one patient from the conventional dose group., Conclusions: The short-term and long-term therapeutic effects of ACTH between 50 IU/d and 0.4 IU/kg/d doses are similar. ACTH therapy is more effective for cryptogenic WS than symptomatic WS. To reduce adverse effects, ACTH therapy should start with a low dose (0.4 IU/ kg each day).

Background: Two cases of West syndrome demonstrated changes in intraocular pressure (IOP) associated with adrenocorticotropic hormone (ACTH) therapy., Cases: A nine-month-old (Case 1) and a six-month-old (Case 2) female infant were treated for West syndrome. In Case 1, the IOP was 14 mmHg in the right eye and 16 mmHg in the left eye before ACTH therapy was started. Although the IOP did not change at the beginning of the treatment, it rose to 36 mmHg in the right eye and 25 mmHg in the left eye after an increase in ACTH dosage. In Case 2, the IOP was 10 mmHg in the right eye and 9 mmHg in the left eye before ACTH therapy, it increased to 18 mmHg in both eyes after treatment was started. The IOP returned to baseline levels in both cases after ACTH therapy concluded., Conclusion: These findings suggest that it is necessary to monitor IOP when ACTH therapy is given to patients with West syndrome.

Historically, adrenocorticotropic hormone was used as a first-line treatment for infantile spasms; however, there has been increasing use of topiramate as initial therapy. Here, we report a retrospective study of adrenocorticotropic hormone (ACTH) and topiramate as initial treatment for infantile spasms. The neurology patient database at the Children's Hospital of Philadelphia was searched using the International Classification of Diseases, Ninth Revision code for infantile spasms, and 50 patients were randomly chosen for chart review. We identified 31 patients receiving either adrenocorticotropic hormone or topiramate monotherapy (adrenocorticotropic hormone n = 12, topiramate n = 19) as a first-line treatment for infantile spasms. A total of 26 patients were symptomatic and 5 cryptogenic. Six patients treated with adrenocorticotropic hormone had resolution of clinical spasms and hypsarrhythmia within a month, but 3 relapsed. Of the 19 patients treated with topiramate, 4 patients eventually, though over a period of 0, 1, 8, or 69 months, had resolution of spasms and hypsarrhythmia.

An 11-month-old boy with multiple congenital anomalies developed West syndrome and ACTH therapy was started. Marked bradycardia during sleep was observed after the 16th day of ACTH therapy. Echocardiography revealed both intraventricular septum and left ventricular free wall thickening with preservation of biventricular function. Both the patient's marked sinus dysfunction and his cardiac hypertrophy were suspected to be related to the ACTH therapy. Sinus function gradually improved after ACTH therapy was withdrawn and treatment with oral beta-agonist was started. We believe that the patient's sinus dysfunction and cardiac hypertrophy were caused by ACTH treatment because of the subacute nature of the onset and the absence of other potentially contributory factors such as infection or respiratory failure. Pediatricians should be aware that cardiac dysfunction could be associated with ACTH therapy for West syndrome.

A one-year-old female patient with infantile spasms who suffered from chronic renal failure was treated with ACTH for the control of frequent tonic spasms. She received 0.005 mg/kg of ACTH for 7 days and then 0.01 mg/kg for 12 days daily. From 12 days after initiation of the treatment, tonic spasms and hypsarrythmia observed on electroencephalography disappeared. During the ACTH treatment, hypertension and gastric bleeding developed, and persisted even with antihypertensive drugs and a H2-blocker treatments. During the ACTH therapy, the serum cortisol level was higher than that in control subjects. Recent advances regarding the metabolism of cortisol have shown that the inactivation of cortisol is impaired in patients with chronic renal failure and that clearance of cortisol from serum is decreased in such patients. It is suggested that the same mechanism was involved in the present patient during the ACTH therapy and that adverse effects of ACTH were related to the high cortisol level in the serum. We conclude that the dose and duration of ACTH therapy should be determined by careful monitoring for the adverse effects of ACTH, and that the serum cortisol level might be a predictor of the side effects of ACTH therapy in a patient with chronic renal failure.

Alpha-melanocyte stimulating hormone (alpha-MSH) and adrenocorticotropic hormone (ACTH) possess properties suggesting that they may be involved in the pathogenesis of restless legs syndrome (RLS). We sought to determine if alpha-MSH and ACTH when administered centrally in rat recapitulate features reminiscent of RLS: increased activity, sleep fragmentation, and periodic movements during sleep. Rats were instrumented with electroencephalography, electromyography, and intracerebral cannulae and recorded for the measurement of sleep, periodic movements, and behavior following intracerebroventricular administration of alpha-MSH, ACTH, or saline. Studied behavior included grooming, locomotion, and rearing during wake and limb movements during sleep. Vigilance states included active wake (AW), quiet wake (QW), slow wave sleep I (SWSI), slow wave sleep II (SWSII), and paradoxical sleep (PS). All rats received normal saline acting as their own controls. Different rats received alpha-MSH in doses of 0.05, 0.5, 1.0, 2.0, and 6.0 microg or ACTH in doses of 0.5, 1.0, and 2.0 microg. Administered alpha-MSH caused an increase in waking behavior and prolongation of sleep latency, while ACTH stimulated waking behavior and fragmented sleep, yielding more AW and less SWSII and PS. Both hormones increased periodic movements during sleep. When administered centrally in rat, alpha-MSH and ACTH stimulate motor activity in wake, cause changes in sleep architecture, and increase periodic movements in sleep. These melanocortin hormones may play a role in the pathogenesis of RLS., ((c) 2008 Movement Disorder Society.)

Few studies have focused on tolerability and adverse events associated with natural adrenocorticotropic hormone injections for treatment of infantile spasms. Using a retrospective chart review of 130 patients, the authors compare major adverse events, weight and blood pressure changes, and unplanned medication changes associated with adrenocorticotropic hormone (ACTH) injections versus other antiepileptic drugs. Children treated with adrenocorticotropic hormone injections experienced significant short-term weight gain and blood pressure elevations, which were readily reversible with weaning off the drug. Twenty-three percent of patients treated with adrenocorticotropic hormone (14 of 60) and 17% of patients treated with other antiepileptic drugs (11 of 65) experienced a major adverse event during treatment. Few patients overall required a change in medication due to intolerable side effects. Despite early changes in weight and blood pressure, short courses of high-dose natural adrenocorticotropic hormone are generally well tolerated with no increased major adverse events when compared to antiepileptic drugs in the treatment of infantile spasms.

We analyzed the clinical factors resulting in hypofibrinogenemia, which is defined as less than 100mg/dl of plasma fibrinogen values determined by a procedure based on the Thrombin-time method. Within a 12-month period, we assayed 5,746 patients (19,309 plasmas) and found 113 patients (1.97%) with hypofibrinogenemia. We categorized these patients as having decreased synthesis of fibrinogen (less than 3.0g/dl of albumin, 140 IU/l of Cholinesterase, and/or 50% on Hepaplastin Test), increased consumption of fibrinogen (more than 10 microg/ml of FDP D-dimer), known side effect of L-asparaginase administration, or other causes. Details are follows: 1) decreased synthesis: 26 patients, suspected of decreased synthesis (albumin: 3.1-3.4 g/dl): 4 patients, 2) increased consumption: 15 patients, suspected of increased consumption (FDP D-dimer: 5.0-9.9 g/dl): 1 case, 3) decreased synthesis combined with increased consumption: 24 patients, suspected of decreased synthesis and/or suspected of increased consumption: 14 patients, 4) side-effect of L-asparaginase administration: 24 patients, 5) heterozygous dysfibrinogenemia: 1 patient, 6) heterozygous fibrinogen deficiency: 1 patient, suspected of heterozygous fibrinogen deficiency: 1 patient, 7) unidentified: 2 patients with West syndrome treated with a combination of ACTH and valproic acid. Three patients with dysfibrinogenemia or fibrinogen deficiency showed normal or slightly prolonged PT values and normal APTT values. These data and our previous reports suggest that heterozygous patients with dysfibrinogenemia or fibrinogen deficiency do not demonstrate markedly prolonged PT and APTT values, differing from patients with afibrinogenemia.

The possibility that changes in eye temperature, measured using infrared thermography (IRT), can detect stress in dairy cattle was examined by six different stimulations of the stress axis. Six cows were given six treatments in a random Latin-square design: 1) Control (saline) 2) ACTH (0.05 mg Synacthen) 3) bCRH (20 mug) 4) bCRH (40 mug) 5) epinephrine (1.4 mug /kg liveweight) and 6) social isolation. Treatments were administered at time 0 and blood samples were taken at -30, -15, 0, 5, 10, 15, 20, 30, 40, 50, 60, 75, 90, 120, 180 and 240 min except for epinephrine which was sampled at -30, -15, -10, -5, 0, 2, 5, 10, 15, 20, 30, 45, 60, 90 and 120 min. Core body temperature was recorded every 10 min and eye images collected every 2 min. Eye temperature and cortisol increased following catheterization (P<0.05). ACTH increased following bCRH, cortisol increased following ACTH and bCRH (P<0.001) and NEFA increased following epinephrine (P<0.001). Core body temperature was unaffected by treatments. Eye temperature was unaffected by CRH and epinephrine but was higher 30 and 60 min following control and ACTH (P<0.001). Our results provide evidence that exogenous HPA stimulation does not increase eye temperature. The increases in eye temperature following catheterization however raise the possibility that a cognitive component may be required for an eye temperature response to occur.

This study examined whether the anti-oxidants ascorbic acid, alpha- or gamma-tocopherol, could modify adrenocorticotrophic hormone (ACTH)-hypertension in Sprague-Dawley rats, a model associated with increased oxidative stress. Systolic blood pressure (SBP) was measured by the tail-cuff method. After four days of ascorbic acid (AA) (200 mg/kg/day drinking) or alpha-tocopherol (500 mg/kg/d i.p. or feed), rats were co-administered ACTH (0.2 mg/kg/day s.c.) or saline for 11 days (prevention studies). In reversal studies, ACTH/saline was administered for 15 days, and from day 9, alpha- or gamma-tocopherol (20 mg/kg/day) was added. ACTH increased SBP compared to saline (p < 0.05). AA or alpha-tocopherol failed to prevent and alpha- or gamma-tocopherol failed to reverse ACTH-induced hypertension. Thus, neither vitamin C (water soluble) nor E (lipid soluble) modified ACTH-induced hypertension in the rat.

West syndrome (WS) is a generalized epileptic syndrome of infancy and early childhood with various etiologies, and consists of a triad of infantile spasm, arrest or regress of psychomotor development and specific electroencephalogram (EEG) pattern of hypsarrhythmia. WS had been believed to be refractory, but recent evidence supports effectiveness of adrenocorticotropic hormone (ACTH) treatment. The ACTH treatment, however, has a problem that it is often accompanied by adverse autonomic symptoms. We therefore examined heart rate variability (HRV) for assessing cardiac autonomic functions in WS and prospectively observed the changes during ACTH treatment. We studied 15 patients with WS and 9 age-matched controls during sleep (EEG stage 2). Compared with controls, the patients with WS were greater in the low-frequency component (LF) of HRV, an index reflecting sympatho-vagal interaction (p = 0.02), but were comparable for high-frequency component (HF) and LF-to-HF ratio (LF/HF), indices reflecting cardiac vagal activity and sympathetic predominance, respectively. During ACTH treatment, heart rate decreased (p < 0.01), LF and HF increased (p < 0.01), and LF/HF did not differ significantly. These results indicate that WS might be accompanied by autonomic changes and that ACTH treatment enhances parasympathetic function and causes bradycardia.

We examined the influence of 8-hydroxy-2-di-n-propylamino tetralin (8-OH-DPAT), a serotonin 1A (5-HT1A) receptor full agonist, on the wet-dog shake response induced by the (+/-)-1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI), a 5-HT2A receptor agonist, in adrenocorticotropic hormone (ACTH)-treated rats. Chronic ACTH (100 microg/rat, s.c.) treatment for 14 d increased the wet-dog shake response induced DOI. The 8-OH-DPAT inhibited the wet-dog shake response induced by DOI in rats with ACTH for 14 d. On the other hand, the 8-OH-DPAT-induced hypothermia and flat body posture were inhibited when ACTH was administered for 14 d. These findings suggest that chronic treatment with ACTH decreased the sensitivity of the 5-HT1A receptor system; however, the inhibitory effects from the 5-HT1A receptors to the 5-HT2A receptor system is not inhibited in ACTH-treated rats.

Purpose: We reviewed our experience with ACTH for the treatment of intractable generalized seizures other than spasms., Methods: Efficacy and adverse effects of ACTH against intractable generalized seizures other than spasms were retrospectively investigated in 15 patients treated between 1991 and 2003. The median age of the patients at ACTH therapy was 42 months. The targeted type of seizure was brief tonic in 6, atypical absence in 6, atonic in 2, and myoclonic in 1. The dose of ACTH was 0.01-0.015 mg/kg in most patients. The effect of ACTH was determined at the end of ACTH therapy, and 3 months and 1 year after ACTH therapy., Results: Seizure freedom was obtained in 13 of 15 patients. However, 6 of them had a recurrence of seizures within 3 months after ACTH therapy. ACTH was the most effective in patients with atypical absence seizures. Statistical analysis showed that the number of injection and total dose of ACTH were smaller in patients with atypical absence seizures than in those with brief tonic seizures. Adverse effects were frequent but serious one was not observed., Conclusion: ACTH therapy was effective in patients with intractable generalized seizures other than spasms. However, its efficacy was often transient. ACTH can be useful for generalized seizures other than spasms but its limitation should be considered.

Objective: In autoimmune polyglandular syndrome types 1, 2, and 4 primary adrenal insufficiency is present, but its diagnosis is often late. We investigated the function of the hypothalamic-pituitary-adrenal axis in a group of patients with autoimmune diseases (AP) without any symptoms and signs of hypoadrenalism., Design: In 10 AP and 12 normal subjects (NS), we studied cortisol (F), aldosterone (A), and DHEA responses to 0.06 microg adrenocorticotropin (ACTH) (1-24) followed by 250 microg, ACTH and F responses to human corticotropin-releasing hormone (hCRH; 100 microg) and insulin tolerance test (ITT) (0.1 UI/kg)., Results: Basal F, A, DHEA, as well as urinary free cortisol and plasma renin activity levels in AP and NS were similar, whereas ACTH levels in AP were higher (P<0.05) than in NS. NS showed F, A, and DHEA response to both consecutive ACTH doses. In AP, the F, A, and DHEA responses to 250 microg ACTH were similar to those in NS, whereas the 0.06 microg ACTH dose did not elicit any significant response. The ACTH responses to hCRH and ITT in AP were higher (P<0.05) than in NS. The F response to hCRH in AP was lower (P<0.05) than in NS, whereas the F response to ITT in AP did not significantly differ from NS., Conclusions: Enhancement of both basal and stimulated corticotrope secretion coupled with reduced adrenal sensitivity to low ACTH dose is present in AP patients without symptoms and signs of hypoadrenalism. This functional picture suggests that normal adrenal secretion is maintained due to corticotrope hyperfunction, suggesting the existence of some subclinical primary hypoadrenalism.

1. Lawrie Beilin has contributed greatly to international hypertension research through both animal and human studies. 2. Animals are used in biomedical research to gain insights that can be extrapolated ultimately to humans. 3. A simple experimental manipulation, adrenocorticotrophin (ACTH) administration, has a range of different cardiovascular effects in different species. 4. Caution should be exercised in extrapolating data from animals to humans.

Here we report an infant who had herpes simplex virus (HSV) encephalitis and sustained severe bilateral damage to the posterior frontal lobes, postcentral gyri, and the thalami despite intravenous acyclovir treatment. At 7 months of age, the patient developed infantile spasms and was treated with corticotropin injections. After 10 days of corticotropin treatment, she developed lethargy, fever, and opisthotonic posturing. Her cerebrospinal fluid again was positive for HSV DNA, indicating recurrent HSV encephalitis, and repeat MRI revealed new lesions of the right frontal, parietal, temporal, and occipital lobes. Immunosuppression by corticotropin may have led to the reactivation of the HSV encephalitis. Corticotropin should be relatively contraindicated for use when a patient has a history of HSV infection, or intravenous acyclovir should be administered concurrently.

Background: Approximately 50% of people with myasthenia gravis present initially with purely ocular symptoms, so called ocular myasthenia and between 50 to 60% of these people will progress to develop generalized disease. The vast majority will do so within the first one to two years. There is controversy surrounding the appropriate management of patients with ocular myasthenia., Objectives: To perform a systematic review of the literature relevant to the treatment of ocular myasthenia and to answer three specific questions. Are there any medical or surgical treatments that have an impact on the risk of progression from ocular to generalized myasthenia gravis? Are there any medical or surgical treatments that improve symptoms of diplopia or ptosis in ocular myasthenia? What is the frequency of side effects associated with treatments used in people with ocular myasthenia?, Search Strategy: We searched the Cochrane Neuromuscular Disease Group Trials Register (searched December 2004), MEDLINE (1996 to 2004) and EMBASE (1980 to 2004) for randomized controlled trials as well as case-control and cohort studies. The titles and abstracts of all articles were read by both authors and the full text of all articles that were of possible relevance was reviewed in full. The references of all manuscripts included in the review were scanned to identify additional articles of relevance and experts in the field were contacted to identify additional published and unpublished data. Where necessary and possible, we contacted authors for further information., Selection Criteria: To be included in the review, studies had to meet three criteria: (a) randomized (or quasi-randomized) controlled study design; (b) active treatment compared to placebo, no treatment or some other treatment; and (c) results reported separately for patients with ocular myasthenia (grade 1) as defined by the Myasthenia Gravis Foundation of America., Data Collection and Analysis: We collected data regarding the risk of progression to generalized myasthenia gravis, improvement in ocular symptoms, and the frequency of treatment-related side effects., Main Results: We identified two randomized controlled trials relevant to the treatment of ocular myasthenia, only one of which reported results in terms of the pre-specified outcome measures used in this review. This study included only three participants and was of limited methodological quality. In the absence of data from randomized controlled trials, we present a review of the available observational data., Authors' Conclusions: There are no data from randomized controlled trials on the impact of any form of treatment on the risk of progression from ocular to generalized myasthenia gravis. The available randomized controlled literature does not permit any meaningful conclusions about the efficacy of any form of treatment for ocular myasthenia. Data from several reasonably good quality observational studies suggest that corticosteroids and azathioprine may be beneficial in reducing the risk of progression to generalized myasthenia gravis.

Systemic sclerosis (SSc) is a multisystem connective disorder in which endothelial damage leads to fibrotic reactions through platelet hyperaggregability and inappropriate release of platelet-derived growth factors. With other colleagues, I have previously reported that melatonin seems to have a direct favorable effect on endothelium (stopping of bleeding symptoms in thrombocytopenic patients). Furthermore, melatonin has been described as performing an antiaggregating activity, and ACTH and vitamin E have been described as increasing melatonin effects. This provided the rationale to treat 5 SSc patients with melatonin plus ACTH and vitamin E. Patients received the treatment for 1 month. The therapy was continued for 2 additional months in patients with stable or responding disease. After 3 months, the stable or responding patients continued the therapy for 2 months and longer. All patients had a partial response after 1 month. Continuing with the treatment, none of the 5 patients had disease progression (average follow-up time of 16.6 months; range, 7-44 months). Toxicity was lacking, with the only side effect being drowsiness. Our experience suggests that the combination of melatonin-ACTH-vitamin E may be safe and effective in patients with SSc.

We studied the effectiveness of our new ACTH treatment strategy for West syndrome (WS), which was based on the results of our previous extremely low-dose ACTH study. The subjects were 31 infants with WS (cryptogenic WS in nine; symptomatic WS in 22). Synthetic ACTH-Z in a dose of 0.005 mg (= 0.2 IU)/kg/day was injected once every morning for at least 2 weeks, up to a maximum of 3 weeks. When this first treatment course achieved full seizure and EEG control, ACTH was tapered to zero over the subsequent 1 or 2 weeks. In the absence of a documented response, the dosage was increased to 0.025 mg (= 1.0 IU)/kg/day for the next 2 weeks (second treatment course). We analyzed the short-term as well as long-term effects, and the incidence of side effects. The first treatment course successfully controlled both spasms and hypsarrhythmia in 17 patients (55%), only spasms in one, and hypsarrhythmia in two. The second treatment course was then introduced in eight of the remaining 14 patients, providing complete suppression of WS in an additional two patients. Regarding the long-term effects, 13 patients (48%), with excellent short-term results and a longer than 1-year follow-up, remained seizure-free. Side effects of a mild degree were seen in 13 patients during ACTH treatment. Our new ACTH step-up method brought 61 and 48% of the patients into short-term and long-term remission, respectively, without significant side effects. The dose of ACTH required to control WS appears to be unexpectedly smaller than the dose we previously used.

Adrenocorticotrophic hormone (ACTH) at pharmacological dosage has marked lipid-lowering effects that may have therapeutic implications. The rationale behind the present investigation was the possible use of ACTH as a lipid-lowering replacement for steroids. Thirty-two healthy individuals were randomly divided into four groups of 8 each. Three ACTH groups received different doses of ACTH(1-24) intramuscularly (0.1 mg, 0.5 mg and 1.0 mg daily for four days) and the control group received NaCl 0.9% 1 ml intramuscularly daily for four days. Moreover, 8 healthy subjects were given ACTH(1-24) 1.0 mg intramuscularly five times at an interval of four days. Blood and urine samples were collected at regular intervals. ACTH treatment at the dose of 1.0 mg daily lowered the serum concentrations of low density lipoprotein (LDL) cholesterol and apolipoprotein B by 28% and 22%, respectively, which is similar to previous observations. ACTH treatment at the doses of 0.5 mg and 0.1 mg gave smaller reductions (17% and 12%, and 9% and 8%, respectively) resulting in near linear dose-response relationships. There were no changes in the control group. Only the ACTH dose of 1.0 mg resulted in significant changes when compared with the control group. During the ACTH administration at four-days intervals, the serum concentrations of LDL cholesterol and apolipoprotein B reached the lowest values at 48 hr after an injection, remained there at 72 hr but were rising again at 96 hr. For effective lipid reduction, an ACTH dose of about 1 mg is needed and it should be given more often than every fourth day, probably every second or third day. With regard to the cortisol exposure, the results should be viewed in the light of calculations, presented in the paper, that 1 mg of ACTH is equivalent to 90 mg of cortisol administered parenterally.

In order to clarify the appropriate usage of adrenocorticotropic hormone (ACTH), the efficacy and side effects of two different regimens of low dose ACTH therapy were compared. Thirty-four patients with West syndrome (WS) were treated with ACTH. The dose of synthetic ACTH-Z was 0.015 mg/kg/dose in 18 patients who were treated between 1996 and 1998 (regimen A), and 0.010 mg/kg/dose in 16 patients who were treated between 1999 and 2001 (regimen B). Patients were classified into cryptogenic and symptomatic groups. Efficacy and adverse effects of ACTH were compared between regimens A and B. Similar analyses were performed after stratification into cryptogenic and symptomatic groups. The efficacy of ACTH was not different between regimens A and B. However, among patients with symptomatic WS, the number of ACTH injections and the dose of ACTH until cessation of spasms were significantly smaller in regimen A than in regimen B. There was no significant difference in these variables between the regimens among those with cryptogenic WS. Adverse effects were not different between regimens A and B. 0.010 mg/kg per day of ACTH will be adequate for cryptogenic WS, but 0.015 mg/kg per day of ACTH is recommended for symptomatic WS.

One hundred and eighty-seven patients with different stages of cerebrovascular insufficiency (CI) have been examined. A diagnosis of CI was based on the results of neurological and neuropsychological study, ultrasonic dopplerography, rheo- and encephalography, electrocardiography, brain MRI and eyegrounds examination. Neurological scales were used for neurological status assessment and further data processing. The study aimed at evaluation of tolerability and clinical efficacy of the medication and complications in CI course. Semax treatment resulted in significant clinical improvement, stabilization of the disease progress and reduced a risk of stroke and transitory ischemic attacks in the disease course. The drug is featured by minor percent of side-effects and is well tolerated by patients, including those of older age groups.

To minimize adverse effects and to get good efficacy of ACTH therapy against West syndrome, we tried a new 2-steps therapeutic protocol consisting of the shortened ACTH therapy and the additional ACTH therapy. In a prospective multi-institutional study, 20 patients with newly diagnosed West syndrome who had failed to respond to high-dose vitamin B6 and zonisamide were treated by this shortened ACTH therapy. Synthetic corticotropin (ACTH-Z 0.025 mg/kg/dose, max 0.25 mg) was administrated intramuscularly seven times on every other day for 14 days. At 1 month after discontinuing corticotropin, spasms and hypsarrhythmia disappeared in 10/20 (50%) and 13/17 (59%) patients respectively. Subsequently, 9 out of the 10 patients with persistent spasms received additional therapy for 1 or 2 weeks with daily intramuscular ACTH-Z, which was tapered off over a few weeks. Including the additional ACTH therapy, the disappearance of spasms and hypsarrhythmia were found in 13 patients (65%) and 13 patients (76%). Adverse effects during the shortened ACTH therapy were fewer than additional ACTH therapy but not statistically significant. Severe adverse effects were not observed in both ACTH therapy. In the 2-steps therapeutic protocol according to the response to ACTH, favorable results were obtained in seizure control, EEG findings and the degree of adverse effects.

Up-to date information about corticotropin (ACTH) in the treatment of infantile spasms and evaluation of the long-term outcome was provided to answer questions about (1) the efficacy of doses of ACTH in comparison with other drugs, especially with vigabatrin, and the efficacy in patients with tuberous sclerosis; (2) tolerability; and (3) long-term outcome. In two studies, high doses were not more effective than low doses but were more effective in another study. In the follow-up of the studies, there was no difference. In an open, randomized, prospective study, the efficacy and relapse rates of ACTH and vigabatrin treatment did not differ significantly. The high response rates in tuberous sclerosis complex were similar. Both drugs had severe side effects. In the long-term follow-up of 20 to 35 years, one third of the patients died, the intellectual outcome of the remaining patients was normal or slightly subnormal, and one quarter and one third of the patients were seizure free. ACTH should be the first choice for treatment of infantile spasms. The side effects of ACTH, unlike those of vigabatrin, are well known, treatable, and reversible. However, an open, prospective study to compare the efficacy, relapse rate, and long-term outcome of treatment with ACTH and vigabatrin is urgently needed. The frequency of visual field defects after vigabatrin therapy should be evaluated.

Malignant pulmonary tumors are rarely accompanied by Cushing syndrome. We encountered 4 patients with adrenocorticotropic hormone (ACTH)-producing pulmonary tumors (3 with carcinoid and 1 with small cell carcinoma). All patients were females aged 33-76 years. In the 4 patients, diagnostic methods, surgical procedures, stage, outcome, and immunohistological findings were evaluated. Subtotal resection of the anterior lobe of the pituitary gland had been performed in 3 patients. However, ACTH did not decrease, and further examination revealed pulmonary tumors. Preoperative blood sampling by catheter examination was performed in 2 patients, of whom 1 showed increased ACTH. Intraoperative blood sampling showed increased ACTH in 1 patient. Lobectomy combined with mediastinal lymph node dissection was performed in 3 patients and lobectomy alone (video-assisted thoracoscopic surgery) in 1. All patients showed a decrease in ACTH after operation without tumor recurrence. Diagnosis is possible by measuring ACTH in pulmonary arterial wedge blood obtained by catherization or in pulmonary venous blood obtained during operation. Surgical resection is effective for ectopic ACTH-producing pulmonary tumors.

Authors present a male patient with Spinal Extradural Lipomatosis, previously treated of a cerebral astrocytoma with surgery and radiotherapy, after which he received ACTH for a long period of time. Clinical manifestations were rachialgia, paraparesia with pain and dysestesias in both lower extremities. Diagnosis was carried out by Magnetic Resonance imaging. After a progressive withdrawal of the treatment with ACTH, the patient achieved a complete recovery and neuroimaging studies showed the dissappearance of the compression caused by the lipomatosis. We carry out a revision of the literature showing data we consider of interest derived from the wide series subjected to study.
