Seroprevalence of Leishmania infection among asymptomatic renal transplant recipients from southern Spain

Abstract

Background: The aim of this article is to assess the seroprevalence of Leishmania infection among asymptomatic renal transplant recipients in a population in the south of Spain.

Methods: Serum samples were screened for immunoglobulin-G antibodies against Leishmania with an indirect fluorescent antibody test.

Results: Of 625 examined serum samples, 30 (4.8%) samples were positive for Leishmania antibodies. Thirteen samples showed titers of 1:80, 15 samples showed titers of 1:160, and 2 samples showed titers of 1:320. None of the patients with positive serology to Leishmania showed signs or symptoms compatible with leishmaniasis.

Conclusion: The prevalence of Leishmania infection found among asymptomatic renal transplant patients reinforces the need for attention in evaluation of these patients in endemic areas.
