Plataforma laboratorial para monitorear el Sars-CoV-2 basada en la vigilancia de influenza y otros virus respiratorios en Perú
In Peru, the COVID-19 pandemic demonstrated the usefulness of having a structured laboratory surveillance system that has been operational for 22 years, based on influenza surveillance; initially in the form of sentinel units, and later strengthened and innovated, with its own resources and with external support, to provide quality information. Biotechnological advances have been implemented for diagnostic confirmation and the capacity of the nat…
Validación y evaluación de una prueba de RT-PCR en tiempo real in house para la detección de Sars-CoV-2 usando un gen específico RdRp y control endógeno GAPDH
The present work validated and evaluated a duplex real-time RT-PCR using specific primers and probes for genes RdRp from SARS-CoV-2 and GAPDH from humans; the latter was used as an endogenous control in all reactions. We evaluated the specificity, the sensitivity, the robustness, the reproducibility, the repeatability, the comparability, and the limit of detection. The predictive positive and negative values (PPV and PNV, respectively) and all th…
Prevalencia de infección por los virus de la hepatitis B, D y por retrovirus en la etnia Matsés (Loreto, Peru)
Observational, cross-sectional, populational study to determine the prevalence of infection by hepatitis B virus (HBV), hepatitis D virus (HDV), human immunodeficiency virus (HIV) and human T-lymphotropic virus type 1 and 2 (HTLV-1/2) in the Matsés ethnic group, after immunization against HBV. ELISA and qPCR tests were used in 963 residents. The prevalence of HBsAg, Anti-HBc and Anti-HBs was 3.32%, 36.03% and 58.67% respectively. In 3.1% of the p…
Búsqueda de infección por hepatitis B en familiares de portadores crónicos de la provincia de Huanta, Ayacucho-Perú
A plan of elimination of the virus of B hepatitis (HBV) is feasible because the immunization has had good impact, as it has been documented in the province of Huanta in Peru. The objective of our study was to determine the frequency of the infection by HBV in relatives of carriers of the surface antigen of the virus of hepatitis B (HBsAg). This cross-sectional study included 39 relatives of chronic carriers, identified at Hospital de Apoyo de Hua…
