Abstract
English (OpenAlex)
Objective: The increasing prevalence of amphetamine/methamphetamine (MA) use is a global problem. Methamphetamine Induced Psychosis (MIP) causes more serious problems, increased burden on health services and has a worse prognosis than methamphetamine use disorder (MUD). In our study, we aimed to measure and compare claudin-5 levels in patients diagnosed with MUD and MIP according to DSM-5 and a healthy control group. Methods: A total of 68 people, including 24 patients diagnosed with MUD, 20 patients diagnosed with MIP and 24 healthy controls, who met the inclusion/exclusion criteria were included in our study. Addiction Profile Index Short Form (API), Positive and Negative Syndrome Scale (PANSS) and sociodemographic data form were applied to the whole sample. Serum claudin-5 levels of the participants were measured by the ELISA method. Results: Claudin-5 level did not show a statistically significant difference between the MUD and the control group (p>0.050). Claudin-5 levels were statistically significantly different between the MUD and MIP group (p<0.050) and between the MIP and control group (p<0.001). In the correlation analysis, a moderate negative correlation was found between claudin-5 and recent daily use in the MUD group (r=-0.535, p<0.010). Conclusion: To the best of our knowledge, our study is the first study in which the claudin-5 level was evaluated in patients diagnosed with MUD and MIP. Our results may contribute to the development of specific diagnostic markers for MIP, the investigation of treatment options, and the identification of biological markers predisposing to psychosis.
