A comparison of miRNAs with proinflammatory cytokines and procalcitonin of sepsis in the intensive care unit A comparison of miRNAs with proinflammatory cytokines and procalcitonin

Abstract

Aim: The development of sepsis, the low efficacy of antibiotics used, long-term antibiotic use, and the development of resistance to antibiotics are significant problems in patients in intensive care units. The use of biological markers is promising for the diagnosis and treatment of sepsis. In this study, proinflammatory cytokines, procalcitonin and four miRNA expressions were analyzed in a time-dependent manner in a patient group and control group, and the correlations between them were examined. Material and Methods: The study included 30 patients in the intensive care unit who were diagnosed with sepsis and applied with SOFA and APACHE-2 scoring and 30 control subjects. Serum samples were taken at 24 hours, 72 hours, and on the 7th day. Analyses according to time were made for interleukin-1 beta, interleukin-6, interleukin-10, TNF-alpha, procalcitonin and four miRNAs (miR-122, miR-146a, miR-150, and miR-223) in the collected samples and comparisons were made between the patients and the control group. Results: At 24 hours, there was a decrease in the miRNA-146a, miRNA-150, and miRNA-122 values and an increase in the miRNA-223 values in the sepsis group compared to the control group. At 72 hours, a decrease was observed in the miRNA-146a, miRNA-150, miRNA-122, and miRNA-223 values in the sepsis group compared to the control group. Discussion: When procalcitonin and inflammatory cytokines were compared with selected miRNAs in the diagnosis, treatment follow-up, and prognosis of sepsis in the intensive care unit, a correlation between procalcitonin levels, proinflammatory cytokines and miRNA-150, miRNA-146a, and miRNA-223 was found.
