Dermatological Conditions Seen in Kidney Transplant Recipients: Prevalence and Risk Factors.

Objectives: In kidney transplant, the use of immunosuppressive drugs, indispensable to avoid organ rejection, implies an increased risk of several infectious and neoplastic diseases. Cutaneous infections have a high incidence in kidney transplant recipients and are diagnosed in 55% to 97% of these patients. The objectives of this study were to identify the most frequent skin diseases and their clinical risk factors within a population of kidney transplant recipients.
Materials and Methods: We reviewed the medical records of 200 kidney transplant recipients at Sahloul Teaching Hospital, Tunisia, between November 2007 and January 2018. We analyzed the clinical data of patients who sought skin consultations with either dermatologists or plastic surgeons within the hospital. We collected patient sociodemographic data, type of donor, and type of immunosuppressive therapy used by recipients. We also obtained history of skin lesions and examination findings.
Results: Among 200 patients included in our study cohort, 131 were male and 69 were female. Age ranged from 6 to 75 years with a mean age of 30.51 ± 12 years. Patients had received kidneys from either living or deceased donors, with available data indicating 96.5% living donors and 3.5% deceased donors. The mean time interval from transplant to first skin consultation was 31 month (range, 3 months to 10 years). Prevalence of various skin conditions was 48.5%. We found that 62.9% of cases were skin infections, 59.8% were drug-induced skin conditions, and 2.9% were skin cancers. The estimated risk factors for skin lesions include use of cyclosporin and duration of immunosuppression.
Conclusions: Our study demonstrated the spectrum of skin conditions that can be expected after kidney transplant. Careful dermatological screening and long-term follow-up are needed for these patients to reduce posttransplant skin complications.
