Circulating Microrna Signatures That Predict Liver Fibrosis Progression In Patients With Hiv-1/Hepatitis C Virus Coinfections
AIDS(2021)
Abstract
Objective: The lack of available biomarkers for diagnosing and predicting different stages of liver disease with a noninvasive strategy is currently one of the main challenges that clinicians are facing. Recent evidence indicates that the plasma levels of specific microRNAs (miRNAs) may be significantly altered in patients with liver injury, including those with HIV type 1 (HIV-1) infections. Design/methods: Large-scale deep sequencing analysis of small RNA expression was performed on plasma samples from 46 patients with HIV-1/hepatitis C virus (HCV) coinfections that did not exhibit liver fibrosis at the time of sampling. Results: A total of 1065 different miRNAs were identified. After a mean of 10.3 years, 26 out of the 46 patients developed liver fibrosis (stage F2-4) and 20 remained without signs of liver fibrosis (stage F0-1). We identified a signature of seven miRNAs: 100-5p, 192-5p, 99a-5p, 122-5p, 125b-2-3p, 1246 and 194-5p, which were highly correlated with progression to liver fibrosis. These seven miRNAs detected liver fibrosis progression with an area under the curve (AUC) of 0.910-0.806. Two miRNAs, 100-5p and 192-5p, which displayed the best AUC values, yielded a sensitivity of 88% and a specificity of 85% for detecting liver fibrosis progression. Conclusion: Our results demonstrated that circulating miRNA levels had potential in predicting liver fibrosis progression before the clinical detection of liver fibrosis or significant clinical signs, such as elevated liver transaminases or platelets. Thus, our results might facilitate predictions of liver injury progression in patients with HIV-1-infections.
