Özet

Aim: As skin disorders may be observed with Hepatitis C, direct-acting antiviral drugs (DAA), dermatological side effects are alsoreported. The objective is to determine the dermatological side effects of DAA drugs.Methods: A study was conducted with chronic hepatitis C patients who used Ombistavir/Paritaprevir/Ritonavir + Dasabuvir (Group1), Sofosbuvir + Ledispavir (Group 2), and sofosbuvir (Group 3) and who supplied the drugs from our hospital. Skin examinations ofthe patients regarding dermatological side effects were conducted. Patients with dermatological side effects and treatment modalitieswere followed.Results: One hundred twelve patients were using Group 1; 69 were using Group 2, 19 were using Group 3. All pruritus patients werein Group 1. It was detected in 56 of 200 patients (28%). Pruritus was more prevalent in patients with diabetes mellitus, hypertension,and heart disease, and the drug could be tolerated in those with no additional systemic comorbidities. Thirty-one patients had renalfailure, and 17 of them underwent renal transplantation, and the pruritus rate was high (57%) in the chronic renal disease Group.Conclusion: Pruritus is the most common side effect observed with DAA drugs used in treating hepatitis C and elderly patients, andpatients with comorbidity and renal transplantation are at high risk.
