COMPARAISON DES VALEURS DE CHARGES VIRALES REALISEES SUR PLASMA ET SUR GOUTTE DE SANG SECHE OUDRIED BLOOD SPOT(DBS) CHEZ LES PERSONNES VIVANT AVEC LEVIRUS DE L'IMMUNODEFICIENCE HUMAINE (VIH) A BAMAKO.

Introduction: The use of blotting paper as a support for quantification of viral load could improve the virological monitoring of patients on Human Immunodeficiency Virus treatment in Mali. The urgency is obvious to us that the coverage in charge is only 10% for the achievement of the 3rd 90. Objective: To assess the performance of viral load screening (sensitivity, specificity, concordance) of DBS from the one spot DBS protocol according to plasma in people living with the human immunodeficiency virus (PLHIV) in Bamako. Methods: A total of 130 blotting papers were made from blood samples received from five sites for monitoring live persons with HIV. These blotting papers thus made were analyzed with the Abbott m2000 apparatus for the purpose of quantifying the viral load with plasma as reference sample. The extraction was done with the m2000SP automatic extractor, following the protocol 1.0 mL HIV-RNA DBS Protocol for paper. Furthermore, the extraction of plasma RNA on the m2000SP was done according to the 0.6 mL HIV-1 RNA protocol. Results: With 130 samples with detectable viral loads, we obtained a correlation of r = 0.837 (p <0.001). In addition, the average difference between the viral load on blotting paper and plasma was 0.512 log / virological copies with a kappa coefficient = 0.708. The threshold of 1000 copies / mL defined as virological success in our study allowed us to obtain a sensitivity of 87% and a specificity of 100%. Conclusion: Decentralized zones or virological plasma monitoring is not accessible, the new Protocol one spot of Abbott laboratory offers an interesting opportunity for the follow-up of these patients with good performance at the threshold of 1000 copies. The use of DBS as a virological support can contribute effectively to the achievement of the 3rd 90. [ABSTRACT FROM AUTHOR]
