摘要：

During dengue outbreaks, acute diagnosis at the patient's point of need followed by appropriate supportive therapy reduces morbidity and mortality. To facilitate needed diagnosis, we developed and optimized a reverse transcription loop-mediated isothermal amplification (RI-LAMP) assay that detects all 4 serotypes of dengue virus (DENV). We used a quencher to reduce nonspecific amplification. The assay does not require expensive thermocyclers, utilizing a simple water bath to maintain the reaction at 63 degrees C. Results can be visualized using UV fluorescence, handheld readers, or lateral flow immunochromatographic tests. We report a sensitivity of 86.3% (95% confidence interval [CI], 72.7-94.8%) and specificity of 93.0% (95% Cl. 83.0-98.1%) using a panel of clinical specimens characterized by DENV quantitative reverse transcription-polymerase chain reaction. This pan-serotype DENV RI-LAMP can be adapted to field-expedient formats where it can provide actionable diagnosis near the patient's point of need. (C) 2015 Elsevier Inc. All rights reserved.
