Preliminary results of a multidisciplinary italian study adopting a psycho-neuro-endocrine-immunological (Pnei) approach to the study of colorectal adenomas

Background and aim of the work: Colorectal mucosal precancerous lesions, metabolic syndrome (MetS) and psychiatric disorders may share a common low-grade local and systemic inflammation. Aim is to report on preliminary data concerning a research adopting a psycho-neuro-endocrine-immune (PNEI) approach to study outpatients undergoing colonoscopy. Methods: A sample of patients undergoing colonosco-py was cross-sectionally investigated. Data on colorectal adenomas, MetS, early atherosclerosis, anxious-de-pressive symptoms, personality traits, and inflammatory markers were statistically analyzed. Results: Sixty-two patients were recruited (female 50%, mean age: 60.8±9.4 years). The prevalence of adenomas and MetS was respectively of 45.2% and 41.9%. Anxiety and depressive symptoms were detected in 16 (32.7%) and 9 (18.4%) subjects, respectively. The presence of adenomas positively correlated with male sex (p=0.01), age (p<0.01), IL-6 (p=0.03), hsCRP (p=0.04), and MetS (p=0.03); it was also associated with hsCRP concentra-tion (aOR=3.81, p=0.03). Conclusions: Proinflammatory atherogenic status, psychological traits, increased mucosal inflammation, and metabolic parameters may share a common a pathogenic mechanism, worth studying.
