Risk Factors for Treatment Failure with Oral Antivirals in HCV
Journal Title: International Journal Of Medical Science And Clinical Research Studies - Year 2022, Vol 2, Issue 05
Abstract
Introduction: Chronic hepatitis C virus (HCV) infection is one of the major cause of cirrhosis of liver and leads to significant morbidity and mortality. In past, HCV therapy was limited to subcutaneous peg interferon plus oral ribavirin, a regimen that was generally poorly tolerated and provided low efficacy, with cure rates below 40% for HCV genotypes 1 and 4, and below 75% for HCV genotypes 2 or 3. The availability of oral direct-acting antiviral (DAA) as treatment for chronic hepatitis C has revolutionized the field. Although current HCV therapies rarely fail to achieve viral eradication, a subset of patients experience treatment failure. Aim: To study the risk factors associated with treatment failure with oral antiviral drugs in patients of Chronic hepatitis C. Materials & Methods: It was a retrorospective study done at Medical Gastroenterology Department, PGIMS, Rohtak in which six years data i.e.from 01.01.2015 to 31.12.2020, pertainining to Eighty Six (86) chronic hepatitis C patients who had treatment failure i.e. SVR failure on oral antiviral drugs was analyzed. Observations: Out of the total 86 patients, there was clear cut male predominance i.e. 54 (62.79 %) with rural background (villages) i.e.73 (84.88%). The age distribution in these 86 patients varied between 10-80 yrs of age and characterstically peak was seen in 31-40 yrs age group i.e.25 patients (29.06 %). The majority of patients had high baseline HCV viral load (> 4 lakhs I.U. /ml) i.e. 52 patients (60.46%). Out of total 86 patients, , 50 patients (58.13%) were cirrhotic, 34 patients (39.53 %) were smokers, 33 patients (38.37%) were alcoholic, 26 patients (30.23 %) had past history of surgical intervention, 9 patients (10.46 %) were diabetic, 9 patients (10.46 %) had got tattoo, 8 patients (9.30%) had history of previous blood transfusion and 13 patients (15.11%) gave history of use of alternative medications. Results: The direct risk factors associated with development of failed SVR in HCV patients are high baseline HCV RNA viral load, cirrhosis, rural background and indirect risk factors are smoking, alcohol and Diabetes Mellitus but large scale studies in future are required to confirm the same.
