Gut microbial dysbiosis or altered gut consortium, in schizophrenia suggests a pathogenic role through the gut-brain axis, influencing neuroinflammatory and neurotransmitter pathways critical to psychotic, affective, cognitive symptoms. Paradoxically, conventional psychotropic interventions may exacerbate this dysbiosis, with antipsychotics, particularly olanzapine, demonstrating profound effects on architecture disruption of bacterial phyla ratios, diminished taxonomic diversity, attenuated short-chain fatty acid synthesis. To address these challenges, novel therapeutic strategies targeting microbiome, encompassing probiotic supplementation, prebiotic compounds, faecal microbiota transplantation, rationalised co-pharmacotherapy, show promise attenuating antipsychotic-induced metabolic disruptions while enhancing efficacy. Harnessing such insights, precision medicine approaches transform antipsychotic prescribing practices by identifying patients at risk side based their profiles. This IUPHAR review collates current literature landscape axis its intricate relationship advocating for integrating microbiome assessments management. Such fundamental shift proposing microbiome-informed prescriptions optimise efficacy reduce adverse impacts would align treatments safety, prioritising 'gut-neutral' gut-favourable drugs safeguard long-term patient outcomes therapy.

Background: Psychosis, particularly schizophrenia (SZ), is influenced by genetic and environmental factors. The neurodevelopmental hypothesis suggests that factors affect neuronal circuit connectivity during perinatal periods, hence causing the onset of diseases. In this study, we performed a genome-wide association study (GWAS) in sample first episode psychosis (FEP). Methods: A 147 individuals diagnosed with non-affective 102 controls were recruited assessed. After venous blood DNA extraction, samples genotyped. Genetic data underwent quality controls, genotype imputation, case-control (GWAS). GWAS, results investigated using an silico functional mapping annotation approach. Results: Our GWAS showed 27 variants across 13 chromosomes at significance (p < 1 × 10−7) total 1976 candidate 188 genes suggestive 10−5), mostly non-coding or intergenic regions. Gene-based tests reported SUFU = 4.8 NCAN 1.6 10−5) genes. Gene-sets enrichment analyses associations early stages life, spanning from 12 to 24 post-conception weeks 1.4 10−3) late prenatal period 10−3), favor hypothesis. Moreover, several matches Catalog strictly related traits, such as SZ, well autism spectrum disorder, which shares some overlap, risk factors, neuroticism alcohol dependence. Conclusions: resulting consequent analysis displayed common liability between psychosis, sum, our investigation provided novel hints supporting SZ and—in general—in psychoses.

Schizophrenia is a serious mental health disorder that confers one of the highest mortality rates all psychiatric illnesses. Although disorder’s psychotic symptoms are treatable with conventional antipsychotics, they remain incurable. Moreover, medication adherence poor, and individuals schizophrenia choose to self-medicate illicit substances, including cannabis. It well-established delta-9-tetrahydrocannabinol (delta-9-THC) component cannabis elicits psychotomimetic effects at high doses; worsens schizophrenia-related psychosis; commonly develops into use in schizophrenia; increases risk earlier-onset those harboring genetic susceptibility. However, derivatives such as cannabidiol (CBD). These products seem alleviate relieve adverse side antipsychotic medications. Therefore, notion has gained traction potential utility cannabis-derived (CBD) adjunct treatment reduce schizophrenia-associated psychosis other symptoms. Currently, preclinical clinical data inconclusive. The present review distinguishes mechanisms underlying vs. cannabis-induced reviews evidence for delta-9-THC-mediated exacerbation CBD-mediated amelioration describes approaches incorporating CBD therapeutic regimen safe efficacious manner.
