Infections after simultaneous pancreas and kidney transplantation: a single-center experience.
Simultaneous pancreas-kidney transplantation (SPKT) is now an accepted therapy for patients with insulin-dependent diabetes mellitus. However, SPKT has an high rate of morbidity and mortality, mainly for infection. From October 1986 to June 2008, in our center 54 patients (18 female; 36 male) affected by diabetes and end-stage renal disease underwent SPKT. The mean duration of diabetes mellitus was 25 +/- 4 years. Only 4 patients had not been treated by dialysis before SPKT. Three operative techniques were used: duct injection (n = 5), bladder diversion (n = 14), and enteric diversion (n = 39). The kidneys were always placed into the left retroperitoneal space. The pancreas was placed extraperitoneally in 5 patients. Thirty-four recipients are alive, including 30 with function of both grafts. Six patients died during the first year after transplantation. Infectious complications were the main cause of death in 3 subjects whereas 98 infections were diagnosed in 51 patients. All patients were treated with immunosuppressive agents: steroids associated with calcineurin inhibitors and mycophenolic acid, or azathioprine. Antibody induction was used in 41 patients with anti-interleukin-2 monoclonal antibody or antithymocyte globulin. We detected 41 episodes of cytomegalovirus infection: systemic (n = 38), bladder (n = 2), and duodenal (n = 1). The 51 bacterial infections were systemic: (n = 10); urinary tract: (n = 22); pulmonary (n = 11); wound (n = 5); intestinal (n = 3). The 5 fungal infections were gastrointestinal tract (n = 3); and arteritis (n = 2). Some patients experienced more than 1 type of infection. The predominant etiology of the systemic infections was bacterial. In conclusion, infectious complications were the main causes of morbidity after SPKT. An early diagnosis of infection, particularly fungal complications, is essential. We recommend administration of broad-spectrum prophylactic antibiotics, antifungals, and antiviral agents.
