Background:Hepatitis C(HCV)remains a serious public health problem in high-risk persons such as patients on chronic *** aimed to estimate the serological prevalence of HCV,the HCV viral load and genotype,and liver fibrosis stage among patients on chronic hemodialysis at the National Renal Health Center in Lima,***:From June 2019 to March 2021,all patients who received chronic hemodialysis were invited to *** who provided written informed consent were *** with HCV-positive serology underwent determination of HCV viral *** from subjects with detectable viral load,underwent determination of HCV ***,HCV infected subjects underwent determination of liver fibrosis using transitional elastography(Fibroscan 402):Metavir score:F0-F1:2.5-7.5 kPa,F2:7.6-9.5 Kpa,F3:9.6-12 Kpa,F4(Cirrhosis):12.1-75 ***:Of the 303 subjects invited to participate,174(57.4%)subjects gave their written *** age was 52 years(range 22-91)and 116(66.6%)were *** serology was positive in 35.1%of patients(61/174);however,the prevalence of positive serology with detectable viral load was 20.11%(35/174).Genotype 1a was the most prevalent(85%).The majority(83.6%)of subjects with detectable viral load had values lower than 800.000 IU/***-nine of those 35 subjects underwent elastography evaluation,and 13(44.8%)of them were found to have stage F2-F4 ***:The prevalence of HCV at the largest reference center for hemodialysis in Lima remains high,with GT1a predominance,viral load usually below 800,000 IU/mL and significant liver fibrosis.
