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...

Description
Summary: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(<5%), medium(5-15%) and high seroprevalence(>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<0.001). The seroprevalence of HCV was investigated in 387 healthcare professionals(29%) working in 14 HU. They were divided into two groups according to their time of professional activity: <10 y (G1) and >10 y (G2). In G1, there were no cases of anti-HCV seropositivity. In G2, 3 members of the staff were anti-HCV seropositive. The mean time of work of the seropositive staff in the HU was 15.6 years. The seroprevalence of HCV was 0.8% when all the healthcare professionals were taken into consideration. There was no statistically significant difference with respect to HCV seroprevalence between G1 and G2 with respect to the time of occupational exposure (p=0.27). the seroprevalence of HCV in patients on HD in MG is 13+/-9.5% and was <10% in 40% of the HU; there was no statistically significant correlation between HDI and seroprevalence of HCV in the healthcare units evaluated; there was a statistically significant correlation between HCV seroprevalence and time of treatment on HD; HCV seroprevalence in the health professionals studied was 0.8% and similar to the literature.
