Gene-environment interaction as a predictor of early adjustment in first episode psychosis.
Abstract Background This study aims to explore the gene-environment interaction hypothesis applied to pre-symptomatic neurodevelopmental phenotypes of first episode psychosis (FEP), that is, genetic factors might increase vulnerability to the effects of environmental adverse conditions occurring at later stages of development. Methods We constructed a schematic ‘two-hit’ model, with Val/Val homozygosity for the catechol- O -methyltransferase ( COMT ) Val158Met polymorphism as the ‘first hit’ and history of obstetric complications and parental socioeconomic status as ‘second hits’. Early adjustment, measured using the Premorbid Adjustment Scale, was considered the main outcome. The study pop…

Age at First Episode Modulates Diagnosis-Related Structural Brain Abnormalities in Psychosis.
Brain volume and thickness abnormalities have been reported in first-episode psychosis (FEP). However, it is unclear if and how they are modulated by brain developmental stage (and, therefore, by age at FEP as a proxy). This is a multicenter cross-sectional case-control brain magnetic resonance imaging (MRI) study. Patients with FEP (n = 196), 65.3% males, with a wide age at FEP span (12-35 y), and healthy controls (HC) (n = 157), matched for age, sex, and handedness, were scanned at 6 sites. Gray matter volume and thickness measurements were generated for several brain regions using FreeSurfer software. The nonlinear relationship between age at scan (a proxy for age at FEP in patients) and…

Impact of NTRK2, DRD2 and ACE polymorphisms on prolactin levels in antipsychotic-treated patients with first-episode psychosis.
Background: Hyperprolactinemia is a common side-effect of antipsychotics (APs), which may trigger serious secondary problems and compromise the adherence to treatment which is crucial for prognosis, especially in patients presenting with a first-episode of psychosis (FEP). Aims: We evaluated, in some cases for the first time, the effect of polymorphisms in multiple candidate genes on serum prolactin (PRL) levels in an AP-treated FEP cohort recruited in the multicenter PEPs study (Phenotype − genotype and environmental interaction; Application of a predictive model in first psychotic episodes). Methods: PRL concentration was measured in serum from 222 patients. A total of 167 polymorphisms w…

Smoking does not impact social and non-social cognition in patients with first episode psychosis.
Abstract Background Many studies having shown significant improvements in non-social and social cognitive performance in smoking FEP patients compared to non-smoking FEP patients. The findings are controversial. This study analyzed the effects of tobacco use on non-social and social cognitive function in a large group of FEP patients and a matched healthy control group. Methods A sample of 335 patients with FEP and 253 healthy controls was divided into four subgroups: control tobacco users (CTU), control non-tobacco users (CNTU), patient tobacco users (PTU) and patient non-tobacco users (PNTU). Demographic variables, tobacco use variables (presence or absence, frequency and duration of toba…
