Abstract
BACKGROUND: Hepatitis C viral (HCV) infection is a major cause of hepatitis during haemodialysis after the control of hepatitis B following vaccination and isolation measures. Magnitude of this problem in India has not been studied and there are only few reports of HCV infection during haemodialysis from this country. This study was conducted to find out the incidence of HCV infection in patients of end stage renal disease (ESRD) and haemodialysis (HD), along with its source and to find out the clinical course of HCV positive patients. METHODS: HCV infection was diagnosed by detecting anti-HCV antibodies using the IIIrd generation ELISA kits. RESULTS: Of the 208 consecutive patients of ESRD accepted for the study, HCV prevalence was 4.3% at the time of start of study. Of the all risk factors studied, past history of jaundice and number of blood transfusion (BT) were significantly higher in HCV positive patients as compared to HCV negative patients. Of the 208 patients, 20 (9.6%) died, 119 (57.2%) lost follow-up and 69 (33.2%) got renal transplant (RT). Incidence of HCV in patients who died, lost follow-up and got RT was 10%, 3.4% and 36.2% while prevalence was 15%, 4.2% and 42% respectively. In these groups, duration of HD was 8.4, 5.2 and 22.7 weeks respectively while the mean blood transfusion (BT) was 1.2, 0.8 and 5.4 in number respectively. Mean age of patients in these groups was 37.85, 37.9 and 32.53 years and percentage of males were 65%, 75% and 89.9% respectively. At no stage of follow-up, patients with HCV infection had any symptoms or high serum bilirubin. Major abnormality was fluctuating ALT in these patients. HCV in 512 units of blood transfusions given to these patients and healthy volunteers was 1.17% and 0.66% respectively. Marked increase of HCV infection while patients were on HD is likely to be due to nosocomial spread. Blood transfusion was not found to be important source of HCV infection. Longer the patients remain on HD; more will be chance of HCV infection. CONCLUSION: It is concluded that HCV is a major cause of concern in haemodialysis patients in India and the predominant source of spread of infection is nosocomial. In our set-up, blood transfusion is not an important source of infection. Majority of these patients remains asymptomatic at least for the short terms follow-up.
