Dengue Virus and Yellow Fever Virus Detection Using Reverse Transcription-Insulated Isothermal PCR and Comparison with Real-Time RT-PCR.

Dengue Virus and Yellow Fever Virus Detection Using Reverse Transcription-Insulated Isothermal PCR and Comparison with Real-Time RT-PCR. Am J Trop Med Hyg. 2020 May 26;: Authors: Stittleburg V, Rojas A, Cardozo F, Muñoz FM, Asturias EJ, Olson D, Paniaga-Avila A, Abeynayake J, Anderson EJ, Waggoner JJ Abstract Real-time reverse transcriptase PCR (rRT-PCR) is the most accurate method for the detection of dengue virus (DENV) and yellow fever virus (YFV) in acute illness. However, performing rRT-PCR is not feasible for many laboratories in regions of endemicity. The current study compared new reverse transcription-insulated isothermal PCRs (the POCKIT DENV and YFV reagent sets) with laboratory-developed rRT-PCRs for both viruses using clinical samples and viral strains from different endemic regions. Sensitivity and specificity of the POCKIT DENV Reagent Set were 87.2% (68/78 samples) and 98.2% of samples (54/55), respectively. The YFV reagent set demonstrated sensitive detection of YFV RNA from six viral strains down to an estimated concentration of 2.5 log10 copies/mL and proved to be specific for YFV. Although the POCKIT assays require RNA extraction, they may provide accurate and less-complex options for molecular testing in laboratory settings where rRT-PCR is not practical.
