Health related quality of life in Iranian hemodialysis patients with viral hepatitis: changing epidemiology.

Background: There are surprisingly a few studies that evaluate the impact of chronic viral hepatitis, which is common in HD (hemodialysis) patients, on HRQOL (health related quality of life).
Objectives: We conducted a study to evaluate the impact of chronic viral hepatitis on HRQOL and to compare their HRQOL with non-infected HD patients via a HRQOL questionnaire.
Patients and Methods: The Iranian adapted version of the Kidney Disease Quality of Life Short Form (KDQOL-SF) version 1.3 questionnaires were filled out by the HD patients. In all HD patients, serum HBsAg, HBS Abs, and HCV Abs [enzyme-linked immunosorbant assay (ELISA)] were routinely checked every six months. Patients were considered to have chronic HBV infection if HBsAg was positive for more than six months. In all HD patients, third generation assay was used to detect HCV infection. Furthermore, serum HCV-RNA (PCR) was examined in anti-HCV-positive patients for confirmation of HCV infection.
Results: in this cross sectional study 4101 patients from 103 dialysis units in Iran between October 2010 and August 2011 were included. Prevalence of hepatitis B and hepatitis C infection was 2.1% and 1.3% respectively. Almost all KDQOL items for viral hepatitis patients had equivalent or better scores than those without viral hepatitis. In the logistic regression after adjustment for age, sex, educational level, marital status, dialysis vintage, HBs Ag positivity and HCV Ab positivity, only age (P < 0.001) and educational level (P = 0.015) had negative impact on quality of life.
Conclusions: Our data show that not only general health and physical activity were preserved but also health perception may be better among HD patients with viral hepatitis.
