Expression and Clinical Significance of the Long Non-Coding RNA OIP5-AS1 in Alcohol Use Disorder.

The present study aimed to investigate the expression of OIP5-AS1 in alcohol use disorder and to explore its potential clinical relevance. A total of 78 patients with alcohol use disorder and 36 healthy controls were enrolled in this study. Clinical data were collected for all participants. The expression levels of OIP5-AS1 were quantified using quantitative real-time polymerase chain reaction (RT-PCR). Receiver operating characteristic (ROC) analysis was subsequently performed to evaluate the diagnostic value of OIP5-AS1. StarBase-based bioinformatics analysis suggested that OIP5-AS1 may function within a miRNA-mediated regulatory network influencing SERPINA3 expression. OIP5-AS1 expression levels, as determined by RT-PCR, were markedly higher in patients with alcohol use disorder than in healthy controls (p < 0.001). Patients were stratified into high- and low-expression groups based on the median OIP5-AS1 level. Comparative analyses of baseline characteristics and clinical parameters showed that body mass index (BMI) was significantly lower in the high-expression group, and this inverse association between OIP5-AS1 expression and BMI remained statistically significant in subsequent logistic regression analyses. ROC analysis demonstrated that OIP5-AS1 had strong diagnostic performance, yielding an area under the curve of 0.9091 (p < 0.0001), with a sensitivity of 100% and a specificity of 75% at the defined cutoff. In conclusion, OIP5-AS1 expression was significantly increased in patients with alcohol use disorder and was inversely associated with BMI. In addition, OIP5-AS1 demonstrated good diagnostic performance in distinguishing patients with alcohol use disorder from healthy controls. These findings suggest that OIP5-AS1 may have potential clinical relevance in alcohol use disorder and merit further investigation.
