AST and ALT APRI Scores and Dysglycemia in Saudi Arabia: A Retrospective Population Study

Abstract

Background: Hyperglycemia is a common symptom of numerous conditions, most notably diabetes mellitus and Cushing’s syndrome, and the liver plays a pivotal role in the regulation of glucose metabolism. The AST–platelet ratio index (AST APRI score) and ALT–platelet ratio index (ALT APRI score) are novel parameters whose association with circulating glucose levels remains poorly studied. Methods: Laboratory data of 14,177 subjects were retrospectively analyzed for the association between AST and ALT APRI scores and fasting blood glucose (FBG) using the Mann–Whitney U and Kruskal–Wallis tests, Spearman’s rank correlation coefficient, prevalence and odds ratio (OR) and ROC curve analysis. Results: AST and ALT APRI scores showed progressive increases with FBG, and the mean FBG was significantly higher in subjects with high AST (104.9 ± 0.33 to 120.8 ± 3.27, p p p p < 0.0001) APRI scores carried a significantly higher risk for hyperglycemia. Importantly, the ALT APRI score was superior to that of the AST APRI score in distinguishing hyperglycemic subjects. Conclusions: The AST and ALT APRI scores are inexpensive, novel markers of FBG and may serve as supportive evidence in the diagnosis and management of hyperglycemic conditions.
