Low serum prealbumin concentration predicts long‐term mortality in maintenance hemodialysis patients with hepatitis B and/or C virus infections.

Background and Aim: A low serum prealbumin concentration is common in maintenance hemodialysis patients with hepatitis B and C and may be associated with mortality. In this study, we assessed Department of Nephrology and Hemodialysis predictive value of a low serum prealbumin concentration on mortality in HD patients using reused low‐flux dialyzers who were infected with hepatitis B and/or C virus. Methods: We used serum prealbumin levels to predict the long‐term mortality of 326 hemodialysis patients. The patients were divided into two groups: group 1 (n = 140, with hepatitis B and/or C virus infections), and group 2 (n = 186, without hepatitis virus infections). Results: During a 5‐year follow‐up, there were 75 deaths due to all‐cause mortality (23.0%). Mortality was significantly higher (P < 0.001) in patients with hepatitis B and/or C infection (44%) than in those without hepatitis infection (8%). Serum prealbumin was lower in the hepatitis infected group and mortality group than in non‐infected group and survival group. Multivariate Cox regression analysis showed that long duration of HD and lower serum prealbumin and albumin were related to mortality in patients undergoing maintenance HD. Receiver operating characteristic curves showed that serum prealbumin had a good prognostic value in predicting mortality in both groups with hepatitis B and/or C virus infection and without hepatitis infection (AUC = 0.792 [95% confidence interval: 0.714–0.87], P < 0.001; cut‐off value = 24.5 mg/dl, sensitivity = 62.3%, and specificity = 88.6%). Conclusion: In HD patients, serum prealbumin was a good prognostic biomarker of mortality in both groups of patients with hepatitis B and/or C virus infections and without hepatitis infections.
