Clinical Utility of Droplet Digital PCR for Human Cytomegalovirus

Abstract: cHuman cytomegalovirus (CMV) has historically been the major infectious cause of morbidity and mortality among patients receiving hematopoietic cell or organ transplant. Standard care in a transplant setting involves frequent monitoring of CMV viral load over weeks to months to determine when antiviral treatment may be required. Quantitative PCR (qPCR) is the standard molecular diagnostic method for monitoring. Recently, digital PCR (dPCR) has shown promise in viral diagnostics, although current dPCR systems h… Show more

“…Some limitations in the clinical sensitivity of dPCR have been observed which may be linked to restricted sample volume inputs for dPCR platforms (44). However, this may be improved by concentration of master mixes (48) and/or sample extracts.…”

“…1 By 5 days PI, total DNA was harvested to quantify the number of viral DNA copies found in these cells using digital PCR with 2 sets of HCMV-specific primers for UL55 and UL123exon4. 37 To accurately determine the number of cells input, genomic DNA copy was quantified using CCR5 gene (because 2 copies exist in 1 cell). 35 Combining the HCMV gene and CCR5 data, in a time course experiment, ;15 copies of HCMV DNA could be detected per infected PB-CD34 cell at days 1, 3, 5, 7, and 14 PI ( Figure 1B; supplemental Figure 2).…”

“…La PCR digitale, capable de quantifier les acides nucléiques circulants sans courbe de calibration, permet de s'affranchir de ces inconvénients [34]. Dans ce cadre, une étude a récemment prouvé l'utilité clinique de détecter l'ADN de cytomégalo-virus humain (hCMV) dans le sang de patients par la technique de dPCR en microgouttelettes [35]. Un suivi régulier de la charge virale est notamment requis pour évaluer la nécessité de prescrire des antiviraux aux patients ayant subi une greffe de cellules hématopoïétiques et qui présentent une hausse de la concentration sanguine en hCMV.…”

“…Un suivi régulier de la charge virale est notamment requis pour évaluer la nécessité de prescrire des antiviraux aux patients ayant subi une greffe de cellules hématopoïétiques et qui présentent une hausse de la concentration sanguine en hCMV. En outre, la PCR digitale en microgouttelettes s'est avérée plus précise que la qPCR, la charge virale quantitative pouvant être mesurée sur une échelle de quatre décades de concentrations [35]. Une autre application de la PCR digitale est la réalisation de tests de diagnostic prénatal non invasifs.…”
