The proportions with each type of ulcer did not differ between participants in the FTC/TDF arm and participants in the placebo arm. Finally, the iPrEx protocol did not use the HSV-2 test manufacturer's suggested cutoffs for indeterminate (IR

Positive correlation was observed between sCD40L plasma levels and T cell immune activation defined by co-expression of CD38/HLA-DR on CD4 and CD8 T cells (Fig. 1d,e), as well as IDO-mRNA expression in ARTnaive patients ([7] and Fig. 1f). However, no correlation was observed between sCD40L and
Version; however, this finding was not confirmed by ulcers identified during STI examinations and may have included ulcers of nonherpetic etiologies. In contrast to the 51 reduction in HSV-2 incidence among women randomized to use a 1 tenofovir topical gel in CAPRISA 004, [9] our results suggest that tenofovir in daily oral FTC/TDF may reduce the occurrence of ulcers in individuals with HSV-2 in
