The seroprevalence of HCV in patients submitted to hemodialysis and health professionals in the State of Minas Gerais, southwest of Brazil

Patients with chronic renal failure(CRF) in hemodialysis(HD) programs comprise a risk group for acquisition of hepatitis C virus(HCV) infection. The objectives were to evaluate the seroprevalence of HCV in patients submitted to HD in State of Minas Gerais(MG), southwest of Brazil; to correlate this seroprevalence with the time of treatment on HD; to investigate the anti-HCV seropositivity in health professionals, to investigate the existence of a correlation between mean HCV seroprevalence and the human development index (HDI). Patients from 66 healthcare units(HU) were studied using a validated questionnaire and considering the positive values of anti-HCV(Elisa III) tests performed in these units between january and december 2003. the majority of patients were male (56.2%), between 41 and 60 years old. The mean seroprevalence of HCV in the 66 healthcare units was 13+/-9.5%; the three-monthly seroprevalence was below 20%, 15% and 10% in 75%, 50% and 40% of healthcare units, respectively. When the HU were grouped according to HCV seroprevalence into low(15%), 20% of the units have low, 42% medium and 37.5% were found to have high seroprevalence. No correlation was found between HDI and HCV seroprevalence (r=0.42; p=0.174) but in the regions in which the HDI was higher, HCV seroprevalence was also higher. There was a positive correlation between HCV seroprevalence and time on HD in 884 patients in the 4 HU (p
