Prevalence of Sexually Transmitted Diseases in Asymptomatic Renal Transplant Recipients

Sexually transmitted diseases, which may be asymptomatic, have the potential to cause serious health problems in renal transplant recipients. The aim of this study was to determine the prevalence of sexually transmitted diseases in sexually active asymptomatic renal transplant patients by using real-time multiplex polymerase chain reaction assays.

This prospective controlled study was conducted between November 2016 and January 2017 in our hospital. Our study group included 80 consecutive, sexually active asymptomatic patients (40 men and 40 women) who had undergone renal transplant in our hospital and who presented to our outpatient clinic for routine follow-up. We also included a control group of 80 consecutive, sexually active nontransplant patients (40 men and 40 women). All patient samples were tested for Gardnerella vaginalis and obligate anaerobes (Prevotella bivia, Porphyromonas species), Candida species, Mycoplasma hominis, Mycoplasma genitalium, Ureaplasma species, Trichomonas vaginalis, Neisseria gonorrhoeae, Chlamydia trachomatis, herpes simplex virus 1 and 2, and Cytomegalovirus by real-time multiplex polymerase chain reaction.

The prevalences of infection with Gardnerella vaginalis and obligate anaerobes (P = .043), Ureaplasma species (P = .02), and Cytomegalovirus (P = .016) were found to be significantly higher in the study group versus the control group. However, there was no difference between the 2 groups regarding the prevalence of Mycoplasma infection (P = .70).

Sexually transmitted diseases may occur more frequently in sexually active asymptomatic renal transplant recipients than in nontransplanted individuals. Real-time multiplex polymerase chain reaction analysis may be a suitable method for determining these pathogens.
