title: The pattern of mucocutaneous infections and infestations in renal transplant recipients.
abstract: Immunosuppression-related mucocutaneous lesions are a significant problem in renal transplant recipients. Infections account for the majority of these manifestations. The aim of this study was to determine the spectrum of mucocutaneous infections and infestations in renal transplant recipients. Over a period of three years, all the renal transplant recipients presenting with mucocutaneous lesions (only with infectious etiology) were included in the study. Diagnosis was based on the clinical appearance and appropriate investigations like scraping for KOH, Tzanck smear, cultures, and skin biopsies whenever necessary. In order to study the temporal effect of immunosuppression on these mucocutaneous infections, the patients were divided into six groups -with durations of graft survival ranging from 0-2, 2-6, 6-12, 12-24, 24-60, and more than 60 months in Groups A-F, respectively. A total of 104 renal transplant recipients presented with 117 infections and infestations. The mean age at presentation was 35.9 +/- 1.2 years (15-65 yrs), and the mean duration after the transplant was 23.3 +/- 3.5 months (1-175). The mean serum creatinine level at the time of clinical presentation was 1.4 +/- 0.07 mg/dl (0.7-6). Twenty-seven patients were on a two-drug regimen, prednisolone and azathioprine, and the rest were on a three-drug regimen with cyclosporine in addition. Out of the total of 117 infections in 104 patients, 57 were viral, 49 were fungal, and 8 were bacterial. Two patients had scabies and one had cysticercosis. The mean time interval for the occurrence of infections after the transplant was earlier in patients on three-drug immunosuppression (12.4 +/- 2.3 months) than in those on the two-drug regimen (51.3 +/- 1.8 months), (p<0.01). The viral infections had the shortest mean time interval for presentation following transplant, 15.8 +/- 1.2 months (p<0.05). We did not find any statistically significant difference with regard to age or sex of the patients, duration after the transplant, or the pattern of infection. Careful examination of transplant patients is essential for early detection and proper treatment, because the mucocutaneous infections can have atypical morphologies and are likely to become extensive if not treated early.
