No differences by randomization group in the proportion of participants with 1 STI examination during which a perianal ulcer (FTC/TDF 3.5 vs. placebo 4.7 , P = 0.37) or groin ulcer (FTC/TDF 2.5 vs. placebo 1.9 , P = 0.51) was identified; results were similar after excluding participants with a positive syphilis rapid plasma reagin test at the same visit. However, symptoms that prompted STI exam
N of cRAI in the past three months being reported more frequently in the placebo arm (P = 0.01). Of the 1,383 participants who tested seronegative for HSV-2 at baseline, 36 (2.6 ) did not contribute person-time to incidence analyses because they were retrospectively found to be HIVinfected at baseline, tested seropositive for HSV-2 at the enrollment visit subsequent to screening, or were lost to f
D if the HSV-2 diagnosis occurred at or after HIV seroconversion, and ulcers were excluded if they occurred at or after HIV seroconversion. We estimated the proportion of participants with 1 ulcer AE classified as Gradeor above (i.e., moderate, severe, or potentially life-threatening), 1 STI examination during which a perianal ulcer was detected, and 1 STI examination during which a groin ulcer
Cell counts (Fig. 1a) and CD4 : CD8 T cell ratio (Fig. 1a), but not correlated with viral load (Fig. 1c). 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
Ination findings. Given the inhibition of HSV-2 replication observed after administration of tenofovir, it is biologically plausible that FTC/ TDF reduced the frequency or severity of ulcers. Unlike acyclovir, tenofovir does not require the presence of the herpes virus for drug activation, suggesting that it may suppress ulcers before phosphorylation occurs. However, topical dosing may be required
