Aims: The effect of HCV eradication following the use of direct-acting antiviral drugs (DAAs) on the glyco-metabolic control is unknown.

Abstract

Aims: The effect of HCV eradication following the use of direct-acting antiviral drugs (DAAs) on the glyco-metabolic control is unknown. Through a meta-analysis of available clinical studies, we investigated whether eradication of HCV infection with interferon-free DAAs is associated with improved glyco-metabolic control in diabetic patients. Methods: We searched the PubMed, MEDLINE and Embase, up to 08th June 2018, for all studies evaluating whether eradication of HCV infection with DAAs is associated with changes in glycated haemoglobin (HbA1c) and fasting plasma glucose (FPG) levels from baseline in human subjects, without restrictions for study type and language. Data were independently extracted by two researchers using pre-specified forms. Random effects meta-analyses were conducted on HbA1c and FPG levels before/after HCV eradication. Results: We found a significant mean reduction in HbA1c levels of − 0.45% (95% CI − 0.60 to − 0.30%; P < 0.001) and in FPG levels of − 22.03 mg/dL (95% CI − 41.61 to − 2.44 mg/dL; P = 0.03), with high heterogeneity between studies (χ2 = 20.4, P < 0.001, I2 = 80% and χ2 = 35.8, P = 0.001, I2 = 94%, respectively). The number of available manuscripts did not allow conducting a meta-regression to elucidate the role of sustained virological response and other confounders in determining the effect of direct-acting antiviral agents on HbA1c reduction. Conclusions: We found a significant improvement in glyco-metabolic control after HCV eradication (in terms of glycated haemoglobin and fasting plasma glucose levels reduction) following direct-acting antiviral treatment in patients with established diabetes, including a consequent positive impact on anti-diabetic therapies.
