A rating scale for drug-induced akathisia has been derived that incorporates diagnostic criteria for pseudoakathisia, and mild, moderate, and severe akathisia. It comprises items for rating the observable, restless movements which characterise the condition, the subjective awareness of restlessness, and any distress associated with the akathisia. In addition, there is an item for rating global severity. A standard examination procedure is recommended. The inter-rater reliability for the scale items (Cohen's kappa) ranged from 0.738 to 0.955. Akathisia was found in eight of 42 schizophrenic in-patients, and nine had pseudoakathisia, where the typical sense of inner restlessness was not reported.

The causes of reduced fertility with cryopreserved semen

Objective: The aim was to formulate practice guidelines for the diagnosis and treatment of hyperprolactinemia. Participants: The Task Force consisted of Endocrine Society-appointed experts, a methodologist, and a medical writer. Evidence: This evidence-based guideline was developed using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system to describe both the strength of recommendations and the quality of evidence. Consensus Process: One group meeting, several conference calls, and e-mail communications enabled consensus. Committees and members of The Endocrine Society, The European Society of Endocrinology, and The Pituitary Society reviewed and commented on preliminary drafts of these guidelines. Conclusions: Practice guidelines are presented for diagnosis and treatment of patients with elevated prolactin levels. These include evidence-based approaches to assessing the cause of hyperprolactinemia, treating drug-induced hyperprolactinemia, and managing prolactinomas in nonpregnant and pregnant subjects. Indications and side effects of therapeutic agents for treating prolactinomas are also presented. (J Clin Endocrinol Metab 96: 273–288, 2011)

Diagnosis and treatment of hyperprolactinemia: an Endocrine Society clinical practice guideline

The Canadian Network for Mood and Anxiety Treatments (CANMAT) previously published treatment guidelines for bipolar disorder in 2005, along with international commentaries and subsequent updates in 2007, 2009, and 2013. The last two updates were published in collaboration with the International Society for Bipolar Disorders (ISBD). These 2018 CANMAT and ISBD Bipolar Treatment Guidelines represent the significant advances in the field since the last full edition was published in 2005, including updates to diagnosis and management as well as new research into pharmacological and psychological treatments. These advances have been translated into clear and easy to use recommendations for first, second, and third- line treatments, with consideration given to levels of evidence for efficacy, clinical support based on experience, and consensus ratings of safety, tolerability, and treatment-emergent switch risk. New to these guidelines, hierarchical rankings were created for first and second- line treatments recommended for acute mania, acute depression, and maintenance treatment in bipolar I disorder. Created by considering the impact of each treatment across all phases of illness, this hierarchy will further assist clinicians in making evidence-based treatment decisions. Lithium, quetiapine, divalproex, asenapine, aripiprazole, paliperidone, risperidone, and cariprazine alone or in combination are recommended as first-line treatments for acute mania. First-line options for bipolar I depression include quetiapine, lurasidone plus lithium or divalproex, lithium, lamotrigine, lurasidone, or adjunctive lamotrigine. While medications that have been shown to be effective for the acute phase should generally be continued for the maintenance phase in bipolar I disorder, there are some exceptions (such as with antidepressants); and available data suggest that lithium, quetiapine, divalproex, lamotrigine, asenapine, and aripiprazole monotherapy or combination treatments should be considered first-line for those initiating or switching treatment during the maintenance phase. In addition to addressing issues in bipolar I disorder, these guidelines also provide an overview of, and recommendations for, clinical management of bipolar II disorder, as well as advice on specific populations, such as women at various stages of the reproductive cycle, children and adolescents, and older adults. There are also discussions on the impact of specific psychiatric and medical comorbidities such as substance use, anxiety, and metabolic disorders. Finally, an overview of issues related to safety and monitoring is provided. The CANMAT and ISBD groups hope that these guidelines become a valuable tool for practitioners across the globe.

Prevalence of hyperprolactinemia in schizophrenic patients treated with conventional antipsychotic medications or risperidone.

Background Weight change and the weight-related health factors of nonfasting serum glucose, serum cholesterol, and diastolic blood pressure levels were analyzed in patients with DSM-III-R schizophrenia and related disorders who received treatment with olanzapine for up to 3 years, and comparisons were made to patients treated with haloperidol. Baseline body mass index (BBMI; kg/m2) and dose (mg/day) were investigated as predictors of long-term weight change experienced during olanzapine treatment. Method This analysis retrospectively examined 573 patients receiving olanzapine and 103 patients receiving haloperidol for 39 weeks or more from a study of 1,996 patients randomly assigned 2:1 to either olanzapine, 5 to 20 mg/day, or haloperidol, 5 to 20 mg/day. After 6 weeks of acute therapy, patients continued for 1 year or more with either double-blind or open-label olanzapine therapy or double-blind haloperidol therapy. Results Mean weight gain for olanzapine-treated patients observed for a median of 2.54 years trended toward a plateau after the first 39 weeks of treatment with a last-observation-carried-forward mean weight change of 6.26 kg (13.8 lb) and a median of 5.90 kg (13.0 lb). This was significantly higher than that for haloperidol-treated patients, whose mean weight gain was 0.69 kg (1.5 lb) after 1.15 years (p 27.6) gained significantly less weight during treatment with olanzapine than their lighter counterparts (BBMI or = . 183). Median serum glucose at endpoint was not significantly associated (p = .096) with weight change for olanzapine. Median serum cholesterol and diastolic blood pressure for olanzapine-treated patients at endpoint showed a relationship with weight change that was statistically (p .05). Conclusion Mean weight gain during olanzapine treatment trended toward a plateau after the initial 39 weeks of treatment with no further significant gain out to 3 years. Higher BBMI was predictive of a lower long-term weight gain, while dose was not a significant predictor of greater longer term weight change. The relationship between weight change and glucose was not statistically significant. The association between weight change and changes in cholesterol as well as changes in diastolic blood pressure was statistically significant but not considered clinically relevant based on the ranges observed.

Long-term olanzapine treatment: weight change and weight-related health factors in schizophrenia.

Objective Clinical factors predicting weight change in patients with schizophrenia and related disorders during acute treatment with the antipsychotic drugs olanzapine, risperidone, and haloperidol were sought through retrospective analyses. Method Six-week body-weight data from 2 trials, study 1 comparing olanzapine and haloperidol (N = 1,369) and study 2 olanzapine and risperidone (N = 268), were analyzed. Effects of 8 clinically relevant covariates--therapy, clinical outcome (Brief Psychiatric Rating Scale), baseline body mass index (BBMI), increased appetite, age, gender, race, and dose--on weight were compared. Results In study 1, olanzapine (vs. haloperidol) therapy, better clinical outcome, lower BBMI, and nonwhite race significantly affected weight gain. Effects of increased appetite and male gender on weight gain were significant for olanzapine but not for haloperidol. In study 2, better clinical outcome, lower BBMI, and younger age significantly affected weight gain. Increased appetite was more frequent during olanzapine treatment than during haloperidol, but not significantly different from risperidone. Significant differences in effect on weight change were found between olanzapine and haloperidol but not between olanzapine and risperidone. No evidence was found that lower antipsychotic drug doses were associated with lower weight gain. Conclusion This report identifies predictive factors of acute weight change in patients with schizophrenia. Similar factors across antipsychotic drugs in predicting greater weight gain included better clinical outcome, low BBMI, and nonwhite race. Factors differing between conventional (haloperidol) and atypical (olanzapine) agents included increased appetite and gender. Choice of atypical antipsychotic drug (olanzapine vs. risperidone) was of minor importance with regard to influence on acute weight gain.

Factors Influencing Acute Weight Change in Patients With Schizophrenia Treated With Olanzapine, Haloperidol, or Risperidone

OBJECTIVE: The effects of olanzapine and divalproex for the treatment of mania were compared in a large randomized clinical trial. METHOD: A 3-week, randomized, double-blind trial compared flexibly dosed olanzapine (5–20 mg/day) to divalproex (500–2500 mg/day in divided doses) for the treatment of patients hospitalized for acute bipolar manic or mixed episodes. The Young Mania Rating Scale and the Hamilton Depression Rating Scale were used to quantify manic and depressive symptoms, respectively. Safety was assessed with several measures. RESULTS: The protocol defined baseline-to-endpoint improvement in the mean total score on the Young Mania Rating Scale as the primary outcome variable. The mean Young Mania Rating Scale score decreased by 13.4 for patients treated with olanzapine (N=125) and 10.4 for those treated with divalproex (N=123). A priori categorizations defined response and remission rates: 54.4% of olanzapine-treated patients responded (≥50% reduction in Young Mania Rating Scale score), compare...
