Evaluation of microRNA expression levels during the craving period of patients diagnosed with severe alcohol use disorder

Abstract

ABSTRACT Background The aim of this study is to compare the serum MicroRNA (miRNA) expression levels on the first day of hospitalization and at the end of the first month of treatment in patients with alcohol use disorder and severe craving symptoms. Through the obtained data, biological agents targeting microRNA for alcohol craving may be developed. Methods The volunteer group consists of four patients diagnosed with severe alcohol use disorder. Sociodemographic and Clinical Information Form, DSM-5 Structured Clinical Interview-Clinical Version (SCID-5-CV), Penn Alcohol Craving Scale (PACS) were used as clinical assessment tools. Peripheral blood samples were obtained at the time of application and on the 30th day. miRNA isolation was performed. The expression levels of 2578 different mature human miRNAs were measured. Results The miRNAs showing statistically significant differences in peripheral blood samples taken on the 1st and 30th days from alcohol users are as follows: miR-19a-3p, miR-6849-5p, miR-6726-5p, miR-6848-5p, miR-186-5p, miR-6889-5p, miR-933, miR-370-3p, miR-5739, miR-103a-2-5p, miR-6860, miR-1254, miR-1260a, miR-3921, miR-127-3p, miR-8064, miR-6870-5p, miR-4688 Conclusions A significant difference was found between the 1st and 30th days in 18 of 2578 miRNAs scanned. It is aimed to investigate these 18 miRNAs in larger sample groups during the alcohol craving period.
