Epidemiology of Infectious Complications in Renal Allograft Recipients in the First Year After Transplant.

Objectives: Renal transplant is one of the best ways to extend life of patients in the end stage of renal disease. Infections are significant causes of morbidity and mortality after renal transplant. The aim of this study was to evaluate frequency, risk factors, causative pathogens, and clinical manifestations in renal transplant recipients from Mashhad City during the first year after transplant.
Materials and Methods: This research was conducted at Montaserie Hospital of Mashhad University of Medical Sciences from March 2013 to July 2015. All studied cases were followed for 1 year. In this retrospective study, our study cohort comprised 193 kidney transplant recipients, including 118 male (61.1%) and 75 female (38.9%) patients, with mean age of 34.4 ± 12.2 years. Of the total patients, 58 received kidneys from living donors (30.1%) and 135 received kidneys from deceased donors (69.9%).
Results: We found that 151 infectious episodes had occurred in 96 patients. The most common infectious site involved the urinary tract (39.1%). Escherichia coli was the most frequently isolated pathogen. The only significant infection risk factor to affect transplant outcomes during the first year was age.
Conclusions: Infections are highly prevalent during the first year after transplant. Prevention and effective antibiotic therapy can reduce the related adverse effects.
