High risk of HIV disease progression after infection through a sexual partner with AIDS
1INSERM U-292, Department of Pubic Health, Epidemiology and Human Reproduction, Paris, France.
Objective:
To investigate whether HIV-1 infection acquired through a severely immunodepressed sexual partner increases the risk of disease progression.
Design:
A prospective cohort of patients infected through sexual contact at a known date and enrolled a few months (median, 2 months) after their first HIV-positive test. At enrolment, 12 subjects stated having had unprotected intercourse (anal or vaginal penetration) with a partner with AIDS within the 6 months prior to their first HIV-positive test. For the same period, 60 subjects stated having had unprotected intercourse with a partner, known to be HIV-positive, but who had not developed AIDS.
Method:
The endpoint was the first occurrence of an HIV-related illness (group IV or AIDS, 1987 Centers for Disease Control and Prevention revised classification). Event-free survival curves since infection were constructed using the Kaplan-Meier method and compared by the log-rank test. The Cox model was used for multivariate analysis.
Results:
Disease progression was more rapid among the 12 subjects who stated having sex with a person with AIDS at a time close to infection, than among the other subjects (P = 0.03). Homosexuality and age at infection were also related to HIV disease progression. The adjusted relative risk of developing an HIV-related illness among those 12 subjects was 3.9 (95% confidence interval, 1.5-9.9).
Conclusion:
Our results confirm the influence of virus-related factors on the onset of immunodepression in subjects infected through sexual contact.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
