Treatment Interruption after Pregnancy : Effects on Disease Progression and Laboratory Findings

الملخص EN

Objective.

To assess clinical progression and inflammatory markers among women stopping or continuing antiretroviral therapy (ART) after pregnancy.

Methods.

ART-naïve women with CD4+ lymphocyte counts >350 cells/uL initiating ART during pregnancy had clinical events and laboratory markers compared over one year postpartum between those stopping (n=59) or continuing (n=147) ART.

Results.

Slopes in CD4 count and HIV RNA did not differ between groups overall and in subsets of ZDV or combination therapy.

The hazard ratio (HR) of a new class B event was 2.09 (95% CI 0.79–5.58) among women stopping ART, 1.24 (0.31–4.95) in those stopping ZDV, and 2.93 (0.64–13.36) among those stopping combination therapy.

Women stopping ART had increased immune activation.

No significant differences were seen in C-reactive protein, lipids, leptin, or interleukin-6.

Conclusions.

While changes in CD4 and HIV RNA levels over one year were similar between women stopping or continuing ART postpartum, higher immune activation among women stopping therapy requires further study.
