Abstract

Cytomegalovirus (CMV) infection is a frequent complication in transplant recipients. This retrospective study compared real-time PCR (rt-PCR) and a pp65 antigen assay as tools for monitoring CMV infection in solid organ (SOT) and bone marrow (SCT) transplant patients. The study tested 2662 samples by rt-PCR, and 1284 specimens with a pp65 antigen assay. 24.3% of the rt-PCR samples and 4.1% of the pp65 antigen samples were positive. 793 specimens, from 230 patients, were tested with both assays. In 6.7% of samples, both tests were positive; in 72.7% both were negative; in the remaining 20.6% of cases, the results were discordant. CMV disease was diagnosed in 50 patients. Results from the two methods were poorly correlated (r=0.460). The sensitivity of rt-PCR (94%) was higher than that of the pp65 antigen assay (27%). Both assays showed high specificity (92% and 99%, respectively). ROC curve analysis, performed separately for SOT and SCT patients, confirmed that rt-PCR outperformed the pp65 assay in the detection of CMV. These findings provide evidence that rt-PCR is a reliable diagnostic tool, and that it can be more effective than pp65 based assays in monitoring CMV infection progression and in guiding therapy in immunocompromised patients.

Abstract

The BK polyomavirus (BKV) is widespread in the general population. In transplant recipients, the patients' weakened immune response may encourage reactivation of latent infection, leading to BKV-related diseases. Rapid and quantitative detection might help to delineate viral reactivation patterns and could thus play an important role in their clinical management. In our study we developed an "in-house" quantitative real-time PCR to detect BKV DNA. The effectiveness of this assay was evaluated by a retrospective analysis of 118 plasma specimens from 22 bone marrow transplant (BMT) recipients and 107 samples from immunocompetent subjects. Eight (36.3%) of the 22 bone marrow transplant recipients tested positive for BKV. The viral load varied from specimen to specimen (10 to 10(5) copies/ml). BKV related disease like hemorrhagic cystitis (HC) was diagnosed in three patients. Specimens from the control group all tested negative. Our results showed the high sensitivity of the real-time PCR, allowing accurate and reproducible measuring of the viral load in order to identify patients at risk for BKV-related diseases. With due caution in interpreting threshold values, the real-time PCR could provide a rapid, sensitive and specific tool for detecting BKV and distinguishing latent and active infection.
