Late spontaneous kidney graft decapsulation after administration of sirolimus in a recipient with chronic hepatitis B and C infection: a case report

Late spontaneous decapsulation of the kidney graft in a patient with hepatitis C and treated with sirolimus: possible pathophysiological association in a rare complication

Late decapsulation with fluid collection is a rare complication of renal transplantation with deleterious effects on kidney function. Its physiopathology is unclear but there might be an association with mammalian target of rapamycin (m-TOR) inhibitors, especially in patients with chronic hepatitis C. We report a case of late spontaneous decapsulation 12 years after kidney transplant in a patient infected with hepatitis C under treatment with sirolimus. He underwent marsupialisation of the collection, sirolimus was converted to cyclosporine and hepatitis C treatment was performed with success. This is the first successful case report of late spontaneous decapsulation of the kidney graft in a patient with hepatitis C.
