A prospective study of cutaneous abnormalities in patients with chronic kidney disease.

There are diverse ways in which the skin is affected by chronic kidney disease (CKD). Various specific and nonspecific skin abnormalities are observed in patients with CKD. The aim of the study was to document the prevalence of skin diseases that commonly occur in patients with CKD on medical treatment and dialysis. A total of 99 patients with CKD were examined for evidence of skin diseases. Ninety-six had at least one cutaneous abnormality attributable to CKD. The most prevalent finding was xerosis (66.7%), followed by pallor (45.45%), pruritus (43.4%), and cutaneous pigmentation (32.3%). Other cutaneous manifestations included dermatitis (27.27%); Kyrle's disease (17.17%); fungal (8.08%), bacterial (11.1%), and viral (5.05%) infections; purpura (10.1%); gynecomastia (4.04%); and yellow skin (5.05%). The common nail changes were half and half nails (36.36%) and onycholysis (13.13%). CKD is associated with various cutaneous abnormalities caused either by the disease or by treatment, the most common being xerosis and pruritus. The dermatologic complications can significantly impair the quality of life in certain individuals; therefore, earlier diagnosis and treatment is important to improve their quality of life.
