Research background

Hepatitis C virus (HCV) is a disease with a significant global impact, affecting approximately 2%-2.5% of the world’s population. New direct-acting antivirals (DAAs) have been introduced over the past few years leading to successful viral eradication.

Research motivation

The association of chronic HCV infection with a wide spectrum of cutaneous manifestations has been widely reported in the literature.

Research objectives

This study aimed to assess the effect of treating HCV with DAAs on the extrahepatic cutaneous manifestations of HCV.

Research methods

A prospective observational study included HCV positive Egyptian patients who were eligible to receive DAAs. Patients with lichen planus or psoriasis were dermoscopically evaluated before treatment and 6 mo after treatment, while patients with hepatic pruritus were assessed using the 12-Item Pruritus Severity Scale over the same period. All patients received DAAs from October 2018 to July 2019 in the form of a three-month course of sofosbuvir/daclatasvir combination.

Research results

A total of 30 from 1039 patients eligible for antiviral treatment were diagnosed with extrahepatic cutaneous manifestations and fulfilled the inclusion criteria of this study. Of these 30 patients, 6 patients had classic lichen planus, 8 patients had psoriasis vulgaris and 16 had hepatic pruritus. All patients with psoriasis showed significant improvement of all psoriatic plaques, and all patients with hepatic pruritus scored 0 on the 12-Item Pruritus Severity Scale indicating total improvement of pruritus. In addition, four of six patients with lichen planus showed complete improvement.

Research conclusions

Treatment of HCV with DAAs was effective in improving HCV-related extrahepatic cutaneous manifestations.

Research perspectives

Further studies with a larger number of patients and more diverse dermatological lesions are warranted to confirm our findings.
