Abstract

The goal of this study was to compare the two operational platforms (Biocentric and Roche CAP/CTM) in the country to assess their degrees of concordance in order to avoid interruptions in the virological follow-up of people living with HIV (PLHIV) in Côte d’Ivoire. HIV1 RNA viral load (VL) of 182 plasmas were measured by means of the 2 platforms in the CeDReS laboratory. The comparison was made by concordance, Bland-Altman (BA) and the appreciation of clinical differences between the measured VL. The proportions of suppressed viral loads (76% and 75%) were similar on the 2 platforms. The mean VLs were 3.43 and 3.66 Log10 /mL respectively on CAP/CTM and Biocentric. According to BA, the bias was 0.23 Log10 in favour of Biocentric and the correlation coefficient of agreement (0.922) was poor. The Kappa coefficients of 0.846 at the detection thresholds and 0.878 at the viral suppression threshold indicated a near perfect level of agreement. Clinically significant differences (> |0.6|) were observed between clinically equivalent VL, with no influence on management. Biocentric and CAP/CTM had good agreement but the power of agreement was low. Clinical differences were not significant, however by interchanging these platforms, communication between biologists and clinicians is useful.
