Department of Psychiatry, Hospital Clínico Universitario de Valencia, 46010 Valencia, Spain; Biomedical Research Institute INCLIVA, 46010 Valencia, Spain; Department of Psychiatry, Faculty of Medicine of Valencia, 46010 Valencia, Spain; Biomedical Research Networking Centre in Mental Health (CIBERSAM), 28029 Madrid, Spain.

Antibiomanic episodes, or as the DSM-5 refers to them, drug-induced manic episodes, pose a clinical challenge that is still poorly understood. There is insufficient information on the most common clinical presentation, patient profile, or underlying aetiopathogenic mechanisms. We present the clinical case of a 67-year-old woman who, after starting treatment (clarithromycin and amoxicillin) for the eradication of Helicobacter pylori, bacteria presented with a brief manic episode, which resolved after withdrawal of both drugs and with antipsychotic treatment.

Article Synopsis
  • Studies suggest that DNA-methylation (DNAm) may be influenced by childhood adversity (CA) and could play a role in the development of psychotic disorders, although the specific mediating effects remain unexplored.
  • Researchers conducted an epigenome-wide association study comparing first-episode psychosis patients (n=366) to healthy controls (n=517) using the Childhood Trauma Questionnaire to create adversity scores, but found that no specific CpG sites significantly mediated the relationship between CA and psychosis after statistical corrections.
  • While several genes showed differential methylation related to CA, and previous studies linked some of these genes to psychosis, the analysis did not identify conclusive biological pathways, hinting at potential factors such as mitochondrial

Department of Psychiatry and Neuropsychology, School for Mental Health and Neuroscience, Maastricht University Medical Centre, Maastricht, The Netherlands; Department of Psychiatry, Yale University School of Medicine, New Haven, CT, USA. Electronic address:

Article Synopsis
  • The study explored the link between the exposome score for schizophrenia (ES-SCZ), which represents cumulative environmental exposures, and cognitive impairments in individuals with schizophrenia spectrum disorders (SSD), their unaffected siblings, and healthy controls.
  • Using assessments like the WAIS-III, DFAR, and BFR, researchers analyzed a sample of 1200 patients, 1371 siblings, and 1564 healthy subjects to evaluate cognitive performance across different domains.
  • The findings showed no significant relationship between ES-SCZ and cognitive abilities in SSD patients; however, siblings and healthy controls exhibited a negative correlation with cognitive scores, indicating that environmental factors may impact those without the disorder differently.
