Pattern of skin and nail changes in chronic renal failure in Nepal: a hospital-based study.
Chronic renal failure, regardless of its cause, often produces specific dermatological abnormalities, which can develop long before failure manifests clinically. Our aim was to study the clinical pattern of skin and nail changes in chronic renal failure and also study the associations of these changes with age, sex, etiology and duration of the chronic renal failure. A total of 104 diagnosed cases of chronic renal failure were included in the study over a period of 1 year. Equal numbers of age- and sex-matched individuals were taken as controls. The male : female ratio was 1.4:1. The mean duration of chronic renal failure was 19 +/- 20 months. Among cases and controls, 72% and 16% had skin changes, respectively. Xerosis was the most common of the skin changes (28%), followed by hyperpigmentation (20%), pruritus (15%), infectious diseases (5%) and other skin changes (33%) in chronic renal failure patients. Abnormal nail changes were seen in 82% of the cases compared to only 8% of the controls. In the cases, white nail was most common followed by brown and half-and-half nail. Pruritus was significantly higher in the dialysis group whereas the nail changes were significantly higher in the non-dialysis group. The skin and nail changes were common in chronic renal failure and manifested in various forms. Thus, thorough inspection of the integument might reveal markers of occult renal disease.
