    Lepromatous Leprosy in a Kidney Transplant Recipient: A Case Report
    (Başkent Üniversitesi, 2011-06) Ardalan, Mohammadreza; Shoja, Mohammadali M.; Ghabili, Kamyar; Ghaffari, Alireza
    Leprosy is a chronic granulomatous disease of the skin and peripheral nerves caused by Mycobacterium leprae. Among mycobacterial infections, leprosy is rare in renal transplant recipients. Here, we report the manifestations of lepromatous leprosy in a 41-year-old renal transplant recipient. Before the renal transplant, the patient had recurrent bullous lesions on his extremities with no systemic complaints. He was on an immunosuppressive regimen that included prednisolone (1 mg/kg/d), cyclosporine (6 mg/kg), and mycophenolate mofetil (2000 mg/d), and had 2 serologically confirmed acute episodes of cytomegalovirus infection that responded favorably to intravenous ganciclovir. The density of his bullous skin lesions decreased after renal transplant. During his regular posttransplant visits, we noticed a decrease in his eyebrow hairs on their lateral margins bilaterally. Later, he developed generalized, symmetric, erythematous papules. With a positive acid-fast bacilli with Fite staining, the results of a skin biopsy showed diffuse foamy histiocyte infiltration in the dermis. These findings are compatible with lepromatous leprosy. After antileprosy therapy, no deterioration of renal allograft function or lepra reactions was noted in a 4-month follow-up. Clinicians should consider leprosy in the differential diagnosis of skin lesions in immunocompromised hosts, and in particular, solid organ transplant recipients in endemic areas.

    Acute Tubular Necrosis After Renal Allograft Segmental Infarction: The Nephrotoxicity of Necrotic Material
    (Başkent Üniversitesi, 2008-12) Ardalan, Mohammad Reza; Shoja, Mohammadali Mohajel; Ghabili, Kamyar; Nasri, Hamid
    Objectives: Renal allograft dysfunction can be caused by renal vessel thrombosis, acute tubular necrosis, hyperacute or acute rejection, nephrotoxicity induced by cyclosporine or tacrolimus, thrombotic microangiopathy, or urinary tract obstruction. Materials and Methods: We describe a renal transplant recipient in whom oliguria developed during the first week after transplant, although his early renal allograft function was good. Results: A Doppler ultrasonographic study revealed a lack of perfusion in the lower pole of the allograft. A perfusion defect was noted in the lower pole that was supplied by a polar artery, which had been damaged during engraftment. Light microscopy disclosed tubular cell necrosis without evidence of vascular or humoral rejection. Conclusions: We suggest that toxic molecules such as tumor necrosis factor-alpha released from a segmental infarcted area can induce tubular cell damage and necrosis leading to renal allograft dysfunction.
