| Summary: | <p>(A) Dot plots showing frequencies of total and intact HIV DNA copies in CD4 T cells measured by the Rainbow assay [<a href="http://www.plospathogens.org/article/info:doi/10.1371/journal.ppat.1013702#ppat.1013702.ref032" target="_blank">32</a>] for individuals of the Acute undetectable (UD, n = 38), Acute UD + 5 (n = 5), Chronic UD (n = 10), Chronic UD + x (n = 57) cohorts. Total HIV DNA is based on RU5 region, intact HIV DNA is based on Ψ, env, gag, pol regions. 15/38 (39%), 5/5 (100%), 4/10 (40%) and 34/57 (60%) displayed a quantifiable intactness result in the Acute UD, Acute UD + 5, Chronic UD and Chronic UD + x cohort, respectively. 4/38 (10%), 1/10 (10%) and 10/57 (17%) displayed an undetectable intactness result in the Acute UD, Chronic UD and Chronic UD + x cohort, respectively. Open symbols represent undetectable values. The other participants in each cohort yielded unreportable values. Grey bars depict median values. (B) Dot plots showing frequencies of total (p = 0.0625) and intact (p = 0.0625) HIV DNA copies in CD4 T cells for paired individuals from the acute cohort (n = 5). (C) Ratio of intact HIV DNA copies to total HIV DNA copies in CD4 T cells for each individual of the Acute UD, Acute UD + 5, Chronic UD and Chronic UD + x cohorts. Grey bars depict median values. Only quantifiable results are plotted. (D) Ratio of intact HIV DNA copies to total HIV DNA copies in CD4 T cells for paired individuals from the acute cohort (n = 5; p = 0.1250). (E) Spearman’s rank correlation between time to ART (from estimated date of infection to treatment initiation, in days) and total HIV DNA copies in CD4 T cells from Acute UD and Chronic UD cohort. (F) Average intra-individual genetic distance for HXB2 coordinates 5089–9443. n represents the number of individuals in each cohort and each dot represents one individual. (G) Average intra-individual genetic distance for HXB2 coordinates 5089–9443 for paired individuals from the acute cohort (n = 5; p = 0.1250). (H-I) Maximum-likelihood phylogenetic trees for the acute (H) and chronic (I) cohorts. The trees include sequences with HXB2 coordinates 5089–9443. Sequences with hypermutations and inversions were excluded from this analysis. HXB2 subtype B is HIV-1 reference genome. (A,C-F) Kruskal-Wallis (Dunn correction for multiple comparisons) and (B,D,G) Wilcoxon tests were performed. Only significant p-values (p < 0.05) are represented on the graphs.</p> <p>(TIF)</p> |
