Hypothesis

Vitamin E levels at HIV-1 acquisition may influence disease progression.

Conclusion

Higher pre-infection vitamin E levels were associated with increased mortality.

Supporting Evidence

  • Each 1 mg/L increase in pre-infection vitamin E was associated with a 1.58-fold higher risk of mortality.
  • The median pre-infection vitamin E level was in the low-normal range (7.5 mg/L).
  • The prevalence of vitamin E deficiency (<5 mg/L) was 21% among participants.

Takeaway

Women with higher vitamin E levels before getting HIV were more likely to die from the disease.

Methodology

Vitamin E status was measured in stored samples from the last pre-infection visit for 67 Kenyan women, and regression analyses were used to estimate associations.

Potential Biases

Potential confounding factors such as socioeconomic status may have influenced the results.

Limitations

CD4 cell counts were not available before April 1998, and the cause of death was unknown for most women.

Participant Demographics

Kenyan women, median age 28 years, with a median of 1 live birth and varying education levels.
