Objectives: The objectives of this study were to investigate the prevalence of erectile dysfunction (ED) among living donor kidney transplant (LDKT) recipients associated with chronic hepatitis B infection in China and to assess the effect of successful LDKT to improve ED.
Materials and methods: From January 2006 to May 2009, erectile function of 26 LDKT recipients associated with chronic hepatitis B infection (Group 1) was evaluated predialysis, during dialysis, and at 6 months posttransplantation using the International Index of Erectile Function, version 5 (IIEF-5). We enrolled 61 age-matched LDKT recipients without hepatitis B/C infection as a control group (Group 2).
Results: The prevalences of ED in Group 1 at predialysis, on dialysis, and 6 months posttransplantation were 23.1%, 80.7%, and 65.3%, respectively. Among Group 2, it was 4.9%, 72.1%, and 41.0%, respectively. The difference in ED between groups was significant at predialysis (P = .031) and 6 months posttransplantation (P = .037). Compared with the dialysis stage, the prevalence of ED at 6 months posttransplantation was significantly decreased in Group 2 (72.1% vs 41.0%; P = .001), but it was not significantly difference from Group 1 (80.7% vs 65.3%; P = .211).
Conclusions: The incidence of ED among hepatitis B recipients was higher than among hepatitis B/C-negative patients at the predialysis and posttransplantation stages. Kidney transplantation is a key treatment to reduce the prevalence of ED among hepatitis B/C-negative recipients, but not those with hepatitis B.
