Abstract

Aim: The incidence and prevalence of end-stage renal disease (ESRD) are extremely high in Taiwan. It is an interesting fact that both the husband and wife in some families of Taiwan suffer from ESRD. Therefore, we attempted to identify the potential risk factors of such couples. Methods: This is a retrospective observational study. Six couples receiving maintenance dialysis in our hospital from 1996 to 2006 were enrolled in this study. Detailed medical history; drugs history including over-the-counter drugs (OCD), analgesics and herbal remedies; occupational history and onset of transitional cell carcinoma (TCC) were recorded. These data are correlated with pre-dialysis laboratory findings. The outcomes of dialysis and TCC were also recorded and analyzed. Results: Two males were Chinese herbal medicine practitioners. All the patients (12/12) had taken Chinese herbs and most of them (10/12) had also taken OCD (especially cold remedies and analgesics). We found all of them had bilateral contracted kidneys, mild proteinuria and trace glucosuria. One patient’s renal biopsy revealed Chinese herb nephropathy. Four patients (33%) suffered from TCC. Three patients expired during follow up due to hyperkalemia, extensive TCC and suicide, respectively. Conclusions: The prevalence of Chinese herbs or compound analgesics abuse is high in couples with ESRD. The clinical features and high incidence of TCC are compatible with drug related chronic tubulointerstitial nephritis. Abuse of offending agents should be considered as a risk factor in family members with ESRD.
