The transmission risk factors of hepatitis B and C infection in dental treating and tattooing among hemodialysis patients

Abstract

For four decades, hepatitis often strikes hemodialysis (HD) patients. The seroprevalence of hepatitis infection in HD ranges from country to country. The study design of two parts, the first partisan estimate of the prevalence of hepatitis B virus (HBV) and hepatitis C virus (HCV) in Baghdad teaching hospital/departmentof HD, and the second part is an association between HBV, and HCV transmission and other suspected risk factors dental office and tattooing. A one hundred patients who underwent serum anti-HBC and anti-HCV examination at Baghdad teaching hospital/department of dialysis were enrolled in the study. The chemiluminescence assay has been used to test HBV and HCV antibodies, and an automated kinetic method was used for liver function tests. HCVAb was detected in thirty-five (35%) dialysis patients, and the total HBcAb and infection HBsAg were detected in five (5%) and zero (0%) respectively. No Co-infection was observed. Seroprevalence results related to transfusion requirement was 4 (7.4%) for total HBcAb, zero (0%) for HBsAg, and 32 (59.3%) for HCVAb. There was no significant difference between blood transfusion and non-transfusion in risk prevalence of total HBcAb and HBsAg, but the risk of HCV infection was significantly higher in the blood transfusion (p < 0.001). In the logit model analysis, the main risk factor for HCV infection in the entire sample was blood transfusion (OR = 20.8, 95% CI: 5.7-75.7, p < 0.001). The association between HCV transmission and risk behavior among patients that contribute its spread in society such as dental healthcare (DHC) (OR = 0.98, 95% CI: 0.925-1.615, p < 0.05) and tattoos (OR = 0.75, 95% CI: 0.503-1.119). A non-significant increase in alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin, while, non-significant decrease in albumin in HCV-positive hemodialysis patients compared with HCV-negative dialysis patients. Our findings indicate a high incidence of HCV virus infection in patients who received blood. However, no transmitting risk appeared from such patients when using dental tools or tattoos tools.
