Introduction The neuroleptic malignant syndrome (NMS) is a potentially life-threatening condition associated to the use of antipsychotics. Since it requires rapid and efficient medical care, high-quality treatment guidelines should be available. In this article, we analyzed and compared different international therapy guidelines for the treatment of schizophrenia, in which NMS treatment recommendations might be contained. Methods We performed an Internet-based search for schizophrenia guidelines via the website of the respective medical society. Guidelines in English, French, Italian, and German from countries whose medical care meets high standards were selected for further analysis and comparison of the NMS treatment recommendations (if present), and their underlying evidence. Results The NMS is mentioned in 12 of 14 guidelines. Only 9 report concrete therapy recommendations (benzodiazepines/dantrolene/bromocriptine/amantadine/intensive care and/or electroconvulsive therapy (ECT)), however, with high heterogeneity. Only 5 guidelines included all possible drug therapy options and ECT, but with differing combination strategies, dosages, application forms, and combinability of options. The level of evidence of the different recommendations was estimated as low. Discussion One-third of the selected guidelines do not report any NMS therapy recommendations. Most guidelines mentioning the NMS do not provide therapy recommendations that include all relevant treatment options. The results show a very high heterogeneity, and the recommendations and statements are of low-evidence levels. The lack of knowledge about the NMS and its treatment may delay the onset of therapy, impair the quality of treatment, and lead to a worse outcome or death. [ABSTRACT FROM AUTHOR]

Objective Malignant catatonia (MC) is an extremely rare, life-threatening disorder. It is characterized by catatonic symptoms accompanied by autonomic instability, hyperthermia, and changes in laboratory values. In many cases, MC is not recognized as such. Evidence-based guidelines are essential to ensure quality of treatment, but what do current national and international guidelines recommend? Method Online search for international guidelines from English-, French-, Italian-, and German-speaking countries whose medical care meets high standards addressing the treatment of MC. These were analyzed and compared regarding statements on MC, recommendations, and strength of scientific evidence. Results Fifteen of the identified guidelines were included. Only 5 of 15 comment on the treatment of MC. As for other rare diseases, no detailed recommendations are available. Suggested therapies are limited to benzodiazepines and electroconvulsive therapy. Levels of evidence and grades of recommendation are predominantly low. Conclusion Many international guidelines do not mention MC. It is not possible to derive a clear algorithm for the treatment of MC from most current guidelines. A thorough update of most guidelines appears to be necessary. Lack of awareness and knowledge of MC among physicians and medical professionals might lead to inadequate or delayed care, worsened outcome, or death. [ABSTRACT FROM AUTHOR]

Tranylcypromine (TCP) is an effective antidepressant with a complex pharmacological profile and a relevant risk of abuse and dependence. Withdrawal phenomena (WP, in the case of TCP-abuse/dependence) or discontinuation phenomena (DP, in the case of absent TCP-abuse/ dependence) subsequent to abrupt termination of TCP are a potentially severe clinical syndrome. We conducted a systematic review of all previously published WP/DP cases following abrupt termination of TCP in order to identify typical clinical presentations and risk factors of WP/ DP and frequency of TCP abuse or dependence within these patients. By searching the Medline and Scopus databases we identified n = 25 cases (cohort WP: n = 18, cohort DP: n = 7). Delirium was found in n = 13 patients (cohort WP: 10/55.6 %; cohort DP: 3/42.9 %), n = 6 demonstrated WP/DP without delirium (WP: 6/33.3 %; DP: 0/0 %) and n = 5 rapid relapse in depression (WP: 1/5.6 %; DP: 4/57.1 %). Mean time until development of WP/DP was 1.9 (WP) and 2.2 (DP) days. Mean duration of WP/DP was 5.7 (WP) and 11.3 (DP) days. All patients of cohort WP were described to feature TCP-abuse/dependence. Patients with delirium were on average older (41.8 years vs. 37.8 years) and featured higher mean prescribed (71.0 mg vs. 38.3 mg) and actually taken daily TCP dosages (285.8 mg vs. 187.7 mg). In conclusion, even termination of lower daily dosages of TCP may result in delirium. Thrombocytopenia features diagnostic value in patients with deliria of unknown etiology. TCP should be administered with great care, especially in dependenceprone patients. [ABSTRACT FROM AUTHOR]

The article presents a case study of a 23-year-old male with bulimia nervosa and major depressive disorder who developed hypogonadism and gynecomastia under duloxetine treatment. The patient complained of swelling and tenderness in the breast after four months of duloxetine medication and bilateral mastectomy. The swellings and tenderness of the breast have subsided after discontinuation of the duloxetine medication.

We report our experience with a 34-year-old patient with schizophrenia, paranoid subtype, who demonstrated an elevation of clozapine serum levels subsequent to pregabalin comedication used for the treatment of schizophrenic anxiety. This observation turned to be dose-dependent. Although the pharmacokinetic profile of pregabalin suggests an exclusive renal elimination, our report supports the presumption of a possible direct or indirect hepatic "effect" of pregabalin.

Introduction: Drug safety surveillance strongly depends on the spontaneous reporting of adverse drug reactions (ADRs). A major limiting factor of spontaneous reporting systems is underreporting (UR) which describes incorrectly low reporting rates of ADRs. Factors contributing to UR are numerous and feature country-dependent differences. Understanding causes of and factors associated with UR is necessary to facilitate targeted interventions to improve ADR reporting and pharmacovigilance. Methods: A cross-sectional questionnaire-based telephone survey was performed among physicians in outpatient care in a federal state of Germany. Results: From n = 316 eligible physicians n = 176 completed the questionnaire (response rate = 55.7%). Most of the physicians (n = 137/77.8%) stated that they report ADRs which they have observed to the competent authority rarely (n = 59/33.5%), very rarely (n = 59/33.5%) or never (n = 19/10.8%); the majority (n = 123/69.9%) had not reported any ADRs in 2014. Frequent subjective reasons for non-reporting of ADR were (specified response options): lack of time (n = 52/29.5%), the subjective evaluation that the required process of reporting is complicated (n = 47/26.7%) or requires too much time (n = 25/14.2%) or the assessment that reporting of an ADR is needless (n = 22/12.5%); within open answers the participants frequently stated that they do not report ADRs that are already known (n = 72/40.9%) and they only report severe ADRs (n = 46/26.1%). Discussion: Our results suggest a need to inform physicians about pharmacovigilance and to modify the required procedure of ADR reporting or to offer other reporting options. [ABSTRACT FROM AUTHOR]

Introduction: There is increasing evidence for an association between treatment with selective serotonin reuptake inhibitors (SSRI) and an increased risk of bleeding events. The most important underlying mechanism appears to be inhibition of serotonin uptake in platelets, an effect that is also present in antidepressants with non-selective serotonin-reuptake inhibition (NSRI). Accordingly, also NSRI may be associated with an increased risk of bleeding. However, there is little data in this regard. Methods: Based on data (spontaneous reports of adverse drug reactions) from 2 pharmacovigilance databases (WHO-database/VigibaseTM; BfArM/AkdÃ-database in Germany) we used a case/non-case approach and calculated reporting odds ratios (ROR) as measures for disproportionality regarding the association of treatment with an agent of the group SSRI/NSRI and haemorrhages. Results: Whereas both positive control agents (ASS and diclofenac) were statistically associated with haemorrhages in both databases (ASS: BfArM/AkdÃ, ROR 13.71 [95 % CI 12.82 - 14.66]/ WHO, ROR 12.96 [95 % CI 12.75 - 13.16]; diclofenac: BfArM/AkdÃ, ROR 2.80 [95 % CI 2.59 - 3.03]/WHO, ROR 2.11 [95 % CI 2.05 - 2.16]), none of the agents of the group SSRI (ROR < 1) was associated with haemorrhages. In group NSRI, only St. John's wort/hypericum was associated with haemorrhages (WHO-database, ROR 1.31 [95 % CI 1.06 - 1.63]). Discussion: Signal detectioning in 2 pharmacovigilance databases suggests that serotonin reuptake inhibition is not associated with an increased risk of bleeding. However, underreporting may have accounted for the evaluated absent associations, particularly concerning SSRI. Regarding the detected increased risk of bleeding associated with hypericum, pharmacokinetic drug-drug interactions may be relevant independent of serotonin reuptake inhibition.

Introduction: Considering the antidepressant agomelatine (AGM) there is a discrepancy between the widespread knowledge of the potential of AGM to cause hepatotoxic adverse drug reactions (ADR) and the availability of corresponding published data. This impedes an adequate assessment of the hepatotoxicity profile of AGM. Methods: We conducted a query of the database of a German Medical Regulatory Body (BfArM) and analyzed spontaneous reports of hepatotoxic ADR. Results: We identified n=58 cases of AGMrelated hepatotoxic ADR. Most frequent ADR was asymptomatic increase of liver enzymes (79%); n=6 patients (10%) with AGM-related toxic hepatitis were reported. Characteristics of patients: female sex (69%), age > 50 years (mean 54 years), polypharmacy (57%), and presence of cardiovascular risk factors (58.5%). Most of the hepatotoxic ADR (90%) were reported to have improved/ recovered after discontinuation of AGM. Discussion: Our evaluation suggests that AGM features a potential to cause severe forms of hepatotoxicity and emphasizes that a pre-existing liver disease is a contraindication for treatment with AGM. Secondly, increased age, female sex and polypharmacy may be risk factors for the development of AGM-related hepatotoxic ADR [ABSTRACT FROM AUTHOR]

Introduction: Little is known about hepatotoxicity associated with valproic acid (VPA), a widely used substance in neuropsychiatry. Methods: All reported cases to the German Federal Institute for Drugs and Medical Devices between 1993 and 2009 of VPA-induced serious hepatic side effects were evaluated. Results: A total of 132 cases of serious VPAassociated liver failure were identifi ed. Approximately one third (34.8 %) occurred under VPA monotherapy, while the majority was seen with VPA plus co-medication, most frequently antiepileptics (34.8 %) and benzodiazepines (16.7 %). A subgroup of 34 cases (25.8 %) had a fatal outcome, the largest number reported to date. Of these,32.4 % were under VPA monotherapy and 67.6 % under VPA plus concomitant medication. Within the study period a signifi cant increase in the total number of reported cases and the subgroup of fatal cases was found. Discussion: This first pharmacovigilance study of VPA-associated liver failure indicates a higher rate of non-fatal and fatal liver failure when VPA is given with co-medication as compared to monotherapy. However, co-medication per se does not increase the risk of fatalities. [ABSTRACT FROM AUTHOR]

It also notes on the mechanism of actions of two drugs including ropinirole and pramipexole.

Quetiapine hemifumarate (QF) is widely used in psychiatry and is associated with regularly occurring side effects such as dizziness and metabolic problems. Apart from these typical adverse events the agent has attracted attention for several rare phenomena (priapism, cholestasis, rhabdomyolysis) that indeed feature anecdotal character, but are nevertheless indispensable for a comprehensive understanding of the factual risk profile of quetiapine. We present the first report of aseptic gingivitis associated with QF in a patient with mental retardation. [ABSTRACT FROM AUTHOR]

The treatment of psychiatric disorders during pregnancy poses a challenge particularly regarding limited pharmacological possibilities. Repetitive transcranial magnetic stimulation (rTMS) and electroconvulsive therapy (ECT) have been described to be successful in single cases, however, guidelines are lacking. In order to contribute to the pool of empirical data that is necessary to create evidenced-based recommendations we present a case of successful treatment of major depression with ECT in a pregnant patient with previous nonresponse to rTMS.
