Parasitic infection in renal transplant recipients

The purpose of this study was to evaluate the prevalence of symptomatic parasitic infections in adult renal transplant recipients. We retrospectively analyzed a sample of 657 adult renal transplant recipients performed from January 2001 to December 2005 for immunosuppression protocol, clinical manifestations, parasite diagnosis, treatments, and outcomes. The prevalence of symptomatic parasitosis infections was 2.4% (16/657). None of the infected patients received cyclosporine in their immunosuppression protocol. Most of the infections were caused by Strongyloids stercoralis (n = 11), followed by Giardia lamblia (n = 3), Toxoplasma gondii (n = 1), and Trypanosoma cruzi: (n = 1). Strongyloides stercoralis was the most frequent agent, causing three cases of hyperinfection including one fatal case. With the new immunosuppressive regimes there must be a suspicion of parasitic infection to avoid the diagnostic delay that can be fatal. Strategies, including empiric treatment for S. stercoralis, must be considered.
