Background: Antibodies against the N-methyl-D-aspartate receptor (NMDAR) have been described in the serum of people with schizophrenia spectrum disorders (schizophrenia). However, the prevalence and clinical relevance of these antibodies in schizophrenia is unclear. This knowledge gap includes the possibility of such antibodies being associated with a distinct clinical profile, which in turn might warrant a distinct treatment approach.

Clozapine is often underused due to concerns about adverse drug reactions (ADRs) but studies into their prevalences are inconclusive. We therefore comprehensively examined prevalences of clozapine-associated ADRs in individuals with schizophrenia and demographic and clinical factors associated with their occurrence. Data from a multi-center study (n = 698 participants) were collected.

Background: Previous studies into mental health service utilisation during the COVID-19 pandemic are limited to a few countries or specific type of service. In addition, data on changes in telepsychiatry are currently lacking.

Aims: We aimed to investigate whether the COVID-19 pandemic is associated with changes in mental health service utilisation, including telepsychiatry, and how these changes were distributed among patients with mental illness during the first COVID-19 outbreak.

Individuals with severe mental illness experience increased morbidity and mortality compared to the general population. Adverse effects of antipsychotics, including weight gain, may contribute to the development of metabolic syndrome (MetS), which is associated with increased risks of all-cause and cardiovascular disease mortality. We aim to provide a comprehensive overview of clinical, biochemical and genetic factors associated with MetS among patients with schizophrenia spectrum disorders using second-generation antipsychotics (SGA).

Article Synopsis
  • Antipsychotic-induced Weight Gain (AiWG) is a significant side effect of antipsychotic medications that can lead to serious health issues, including diabetes and decreased quality of life, but optimal treatment strategies are still unclear.
  • This study is a randomized, double-blind trial that will compare the effects of metformin against a placebo in 256 overweight patients (BMI > 25) with schizophrenia who have been on antipsychotics for at least three months.
  • The primary goal is to assess changes in body weight after 26 weeks of treatment, with secondary outcomes including the impact on metabolic syndrome, quality of life, and overall health, as well as evaluating cost-effectiveness and genetic factors related to BMI.
