Successful Clozapine Rechallenge After Clozapine-Induced Severe Anemia: A Case Report.

INTRODUCTION: Clozapine, a second-generation antipsychotic (SGA), is considered the gold standard medication to treat patients with treatment-resistant schizophrenia (TRS). Despite its efficacy, clozapine is associated with adverse effects, notably neutropenia and agranulocytosis. Other hematological adverse effects are less common. Severe anemia is a rare adverse effect seldom reported in the literature and is typically associated with pure red cell aplasia (PRCA). Nevertheless, the benefits of clozapine in managing TRS make rechallenge a reasonable option. CASE REPORT: We present the case of a 35-year-old man with TRS, resistant to previous antipsychotics, who experienced severe anemia during clozapine treatment. An investigation for clozapine-induced anemia revealed PRCA on myelogram. After discontinuing clozapine, the patient's hemoglobin levels recovered. Subsequent treatments with olanzapine, zuclopenthixol, and aripiprazole proved ineffective, leading us to consider a clozapine rechallenge. The rechallenge, monitored for 58 days, resulted in improved psychiatric symptoms and stable hemoglobin levels. The patient remained stable during 6 months of follow-up, with no hematological changes. DISCUSSION: PRCA is a very rare adverse effect of clozapine. The cause of drug-induced PRCA is still unknown; for clozapine, there are no studies. Rechallenge after a severe and rare adverse effect is a complex decision. This case is the first to report a successful clozapine rechallenge following severe anemia without other blood dyscrasias, emphasizing the imperative need for close monitoring during the rechallenge process. Further study is warranted to understand the predictive factors for a successful outcome in clozapine rechallenges.

Profile of female survivors of sexual violence in the first 6 months of the COVID-19 quarantine in the city of Campinas, Brazil: A cross-sectional retrospective study.

OBJECTIVES: Describe the characteristics and changes in the profile of women who sought care after experiencing sexual violence (SV) during the first six months of the COVID-19 pandemic in a Brazilian city. METHODS: This is a cross-sectional retrospective study. Data from emergency care and legal abortion requests of women assisted at the Women's Health Care Center Hospital (School of Medical Sciences, University of Campinas, Brazil) due to SV experienced between March 23 and August 23, 2020 (Quarantine Group, QG), were collected and compared with data from the same period of the previous biennium (Comparison Group, CG). χ2 and Fisher's exact tests were used to compare groups; the significance level was 5%. RESULTS: Data for 236 women were analyzed; 70 women were included in the QG and 166 in the CG. In the QG, there was a restriction in the area of origin of women, with a higher proportion of women who lived in Campinas (P = 0.0007) and a higher frequency of chronic SV (P = 0,035). There were no rapes associated with the use of social media or apps in the QG, but 9.8% of women in the CG experienced rape associated with the use of social media or apps. There were higher rates of domestic violence (P = 0.022) and intimidation through physical force (P = 0.011) in the first two months. CONCLUSION: The COVID-19 quarantine affected the profile of women who sought care after experiencing SV. The quarantine resulted in changes in the area of origin of patients, hindering access to health services and leading to higher rates of chronic and domestic SV, particularly in the first 2 months of the pandemic.

Nonsuicidal self-injury in undergraduate students: a cross-sectional study and association with suicidal behavior.

The objective of this study was to investigate nonsuicidal self-injury (NSSI) in graduates and correlate NSSI with sociodemographic profile, suicidal behavior, and prior mental health disorders. The study is part of a larger survey investigating sociodemographic profile, quality of life and mental health in undergraduates from one of Brazil´s largest universities. A bespoke questionnaire was devised about NSSI based on the DSM5 diagnostic criteria. The data were analyzed using the statistical analysis package SPSS. A total of 6.906 university students took part in the study. Regarding NSSI, 17.8% of students reported at least one episode in their lifetime, and 35% reported age at NSSI onset of 14-16 years. Self-injurious behavior was associated with female gender, self-reported black skin color, dissatisfaction with the chosen course, history of bullying and prior mental disorder. There was a ten times greater risk of suicidal behavior among self-injurers and this risk was higher still for recurrent NSSI.

Offspring of mothers with bipolar disorder: a systematic review considering personality features.

OBJECTIVE: To examine personality/temperament features and mental health vulnerability in offspring of mothers with bipolar disorders (BD), including dimensions which may impact psychological characteristics or therapeutic measures. METHODS: A systematic review, following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, was conducted to search for original articles that investigated personality/temperament features of offspring of women with BD and emotional factors involved in the mother-child relationship. The electronic search was performed in the PubMed, Web of Science, and PsycINFO databases from February 2010 to February 2017. RESULTS: Ten quantitative studies were included in the analysis: seven from the United States, two from Brazil, and one from Canada. The narrative synthesis was categorized into three dimensions: 1) reliability of instruments for prediction of future psychopathology in offspring; 2) environmental risk factors for offspring; and 3) early interventions. The findings showed impairments in the offspring's lives, high rates of behavior and temperament problems, and psychiatric disorders. CONCLUSION: BD is a frequent psychiatric disorder, and the offspring of mothers with this condition are exposed to complex family relationships and psychosocial difficulties. If they are to ensure a good provision of mental health and psychosocial care to this unique population, early interventions must not neglect their contextual specificities.

Patients with Schizophrenia Undergoing Gastric Bypass Surgery: a Case Series Study.

PURPOSE: Obesity affects approximately 45-55% of persons with schizophrenia and is more difficult to manage in these individuals than in the general population, apart from being an additional factor for morbidity and premature mortality. Although bariatric surgery is considered the most effective long-term treatment for severe obesity, there are few reports on the outcomes of this procedure in persons with schizophrenia. This study aimed to evaluate weight loss and psychiatric symptoms in persons with obesity and schizophrenia after bariatric surgery. MATERIALS AND METHODS: Five persons with schizophrenia and moderate to severe obesity who underwent bariatric surgery were followed up for 2 years. Anthropometric data were collected, and psychiatric symptoms were evaluated using the Positive and Negative Syndrome Scale (PANSS), which assessed the pre- and postoperative occurrence and severity of symptoms of schizophrenia. RESULTS: The mean body mass index before surgery was 43.5 ± 5.2 kg/m2 and decreased to 28.1 ± 1.9 kg/m2 1 year postoperatively. The mean percentage of total postoperative weight loss was 30.7 ± 6.8% after 6 months, 34.7 ± 7.9% after 1 year, and 34.3 ± 5.5% after 2 years. Before surgery, all subjects were in remission based on the PANSS. Postoperative evaluations showed that the participants had no relapse of psychiatric symptoms (p > 0.05 for the three PANSS dimensions throughout the follow-up period). There were no considerable changes in their medication regimens. CONCLUSIONS: These findings suggest that bariatric surgery may be a viable treatment option for stable patients with schizophrenia if they have a preoperative assessment and close management and involvement by mental health professionals throughout the course of treatment.

Diagnosis and implications in the therapeutic management of patient with afebrile neurolepctic malignant syndrome.

This report aims at raising clinical awareness for the diagnosis of atypical presentations of neuroleptic malignant syndrome (NMS). We describe the case of a female patient with NMS symptoms, except fever, after starting the use of chlorpromazine. The afebrile condition delayed the consideration of NMS by the emergency clinicians who provided her initial assessment. Before this consideration, an anticholinergic agent, not recommended at this condition, was inadvertently prescribed. This might have contributed to the worsening of symptoms. NMS is a life-threatening idiosyncratic reaction most often seen as complication of antipsychotic treatment. Its clinical spectrum is broad and its diagnosis should be considered even if the patients do not fulfill all the possible described symptoms.

Pharmacogenetics of Risperidone and Cardiovascular Risk in Children and Adolescents.

Objective. To identify the frequency of obesity and metabolic complications in child and adolescent users of risperidone. Potential associations with clinical parameters and SNPs of the HTR2C, DRD2, LEP, LEPR, MC4R, and CYP2D6 genes were analyzed. Methods. Samples from 120 risperidone users (8-20 years old) were collected and SNPs were analyzed, alongside assessment of chronological and bone ages, prescribed and weight-adjusted doses, use of other psychotropic drugs, waist circumference, BMI z-scores, blood pressure, HOMA-IR index, fasting levels of serum glucose, insulin, cholesterol, triglycerides, transaminases, and leptin. Results. Thirty-two (26.7%) patients were overweight and 5 (4.2%) obese. Hypertension was recorded in 8 patients (6.7%), metabolic syndrome in 6 (5%), and increased waist circumference in 20 (16.7%). The HOMA-IR was high for 22 patients (18.3%), while total cholesterol and triglycerides were high in 20 (16.7%) and 41 (34.2%) patients, respectively. SNP associations were found for LEP, HTR2C, and CYP2D6 with BMI; CYP2D6 with blood pressure, ALT, and HOMA-IR; HTR2C and LEPR with leptin levels; MC4R and DRD2 with HOMA-IR; HTR2C with WC; and LEP with ALT. Conclusions. Although not higher than in the general pediatric population, a high frequency of patients was overweight/obese, with abnormalities in metabolic parameters and some pharmacogenetic associations.

Hyperprolactinemia in Children and Adolescents with Use of Risperidone: Clinical and Molecular Genetics Aspects.

OBJECTIVE: In children and adolescents treated with risperidone, hyperprolactinemia is a frequent complication that may have clinical repercussions. Several genes have been associated with this occurrence. The aim of this study was to evaluate the frequency of hyperprolactinemia in children and adolescents treated with risperidone, and its associations with clinical and pharmacological data and certain polymorphisms of the following genes: Dopamine receptor D2 (DRD2), 5-hydroxytryptamine (serotonin) receptor 2C (HTR2C), cytochrome P450, family 2, subfamily D, polypeptide 6 (CYP2D6), leptin (LEP), leptin receptor (LEPR), melanocortin 4 receptor (MC4R), and scavenger receptor class B, member 2 (SCARB2). METHODS: The study included patients using risperidone (8-20 years old) and healthy subjects not exposed to the medication. Psychopathological symptoms, doses, and duration of treatment with risperidone, sex, skin color, body mass index (BMI), use of other psychotropic drugs, and polymorphisms of DRD2, HTR2C, CYP2D6, LEP, LEPR, MC4R, and SCARB2 genes were evaluated. RESULTS: There were 120 patients and 197 individuals not exposed to risperidone who were evaluated. Among patients, hyperprolactinemia was found in 79 (65.8%) cases, with no differences regarding sex, skin color, or being in monotherapy with risperidone (26.7% of total patients) or not. The level of prolactin was not correlated, either in case or control groups, with chronological age, bone age, prescribed dose of risperidone, weight-adjusted dose of risperidone, or BMI (p > 0.05), but was negatively correlated with the treatment duration (r = -0.352, p = 0.001 among cases; and r = -0.324, p = 0.039 among controls). There were significant differences in use of risperidone between patients and healthy subjects without the medication in the frequency of the polymorphisms of the DRD2, HTR2C, and LEP genes. Considering both sexes together and also specifically among females, the occurrence of hyperprolactinemia was higher in the presence of the C allele of the rs6318 single nucleotide polymorphisms (SNP) of the HTR2C gene. CONCLUSIONS: This group of children and adolescents with or without isolated use of risperidone presented with a high frequency of hyperprolactinemia, although asymptomatic, and associated, when considering only females or both sexes together, with being a carrier of the C allele of the rs6318 SNP of the HTR2C gene.
