Prospective, comprehensive, and effective viral monitoring in Cuban children undergoing solid organ transplantation.

Purpose: In Cuba, viral monitoring in the post-transplant period was not routinely performed. The aim of this research is to identify the most frequent viruses that affect transplanted Cuban children, by implementing a viral follow-up during the post-transplant period.

Methods: The study population included all Cuban pediatric patients who underwent solid organ transplantation (SOT) between November 2009 and December 2012.

Assessment of infection with polyomaviruses BKV, JCV and SV40 in different groups of Cuban individuals.

We investigated the frequency of BKV, JCV and SV40 reactivation in three groups of Cuban patients by multiplex nested PCR assay of 40 paraffin-embedded colorectal neoplasm tissues, 113 urine samples, and 125 plasma samples from 27 transplant recipients, and cerebrospinal fluid (CSF) from 67 HIV-1-infected individuals with central nervous system (CNS) disorders. None of these polyomaviruses were detected in colorectal neoplasms. JCV DNA was detected in 2 of 67 patients (2.
