1.  HIV-1 Disease Progression in Breast-Feeding and Formula-Feeding Mothers: A Prospective 2-Year Comparison of T Cell Subsets, HIV-1 RNA Levels, and Mortality 
The Journal of Infectious Diseases  2006;195(2):220-229.
Background
There is conflicting evidence regarding the effects of breast-feeding on maternal mortality from human immunodeficiency virus type 1 (HIV-1) infection, and little is known about the effects of breast-feeding on markers of HIV-1 disease progression.
Methods
HIV-1–seropositive women were enrolled during pregnancy and received short-course zidovudine. HIV-1 RNA levels and CD4 cell counts were determined at baseline and at months 1, 3, 6, 12, 18, and 24 postpartum and were compared between breast-feeding and formula-feeding mothers.
Results
Of 296 women, 98 formula fed and 198 breast-fed. At baseline, formula-feeding women had a higher education level and prevalence of HIV-1–related illness than did breast-feeding women; however, the groups did not differ with respect to CD4 cell counts and HIV-1 RNA levels. Between months 1 and 24 postpartum, CD4 cell counts decreased 3.9 cells/µL/month (P< .001), HIV-1 RNA levels increased 0.005 log10 copies/mL/month (P = .03), and body mass index (BMI) decreased 0.03 kg/m2/month (P< .001). The rate of CD4 cell count decline was higher in breast-feeding mothers (7.2 cells/µL/month) than in mothers who never breast-fed (4.0 cells/µL/month) (P = .01). BMI decreased more rapidly in breast-feeding women (P = .04), whereas HIV-1 RNA levels and mortality did not differ significantly between breast-feeding and formula-feeding women.
Conclusions
Breast-feeding was associated with significant decreases in CD4 cell counts and BMI. HIV-1 RNA levels and mortality were not increased, suggesting a limited adverse impact of breast-feeding in mothers receiving extended care for HIV-1 infection.

2.  Latent Tuberculosis Detection by Interferon γ Release Assay during Pregnancy Predicts Active Tuberculosis and Mortality in Human Immunodeficiency Virus Type 1-Infected Women and Their Children 
The Journal of Infectious Diseases  2010;202(12):1826-1835.
Background. We evaluated the prognostic usefulness of interferon γ release assays (IGRAs) for active tuberculosis and mortality in Kenyan human immunodeficiency virus type 1 (HIV-1)-infected women and their infants.
Methods. Prevalence and correlates of Mycobacterium tuberculosis-specific T-SPOT.TB IGRA positivity were determined during pregnancy in a historical cohort of HIV-1-infected women. Hazard ratios, adjusted for baseline maternal CD4 cell count (aHRCD4), were calculated for associations between IGRA positivity and risk of active tuberculosis and mortality over 2-year postpartum follow-up among women and their infants.
Results. Of 333 women tested, 52 (15.6%) had indeterminate IGRA results. Of the remaining 281 women, 120 (42.7%) had positive IGRA results, which were associated with a 4.5-fold increased risk of active tuberculosis (aHRCD4, 4.5; 95% confidence interval [CI], 1.1–18.0; P = .030). For immunosuppressed women (CD4 cell count, <250 cells/µL), positive IGRA results were associated with increased risk of maternal mortality (aHRCD4, 3.5; 95% CI, 1.02–12.1; ), maternal active tuberculosis or mortality (aHRCD4 P = .045 , 5.2; 95% CI, 1.7–15.6; P = .004), and infant active tuberculosis or mortality overall (aHRCD4, 3.0; 95% CI, 1.0–8.9; P = .05) and among HIV-1-exposed uninfected infants (aHRCD4, 7.3; 95% CI, 1.6–33.5; P = .01).
Conclusions. Positive IGRA results for HIV-1-infected pregnant women were associated with postpartum active tuberculosis and mortality among mothers and their infants.
