    Abstract:
    OBJECTIVE: The aim of this study was to assess risk for developed active tuberculosis in HIV infected IDU oblation and relate with immunodeficiency degree. METHODS: Longitudinal follow-up was realized, the period of study was 9 years, in HIV seropositive IDU patients. Control group was HIV seronegative IDU. CD4+ lymphocytes count and cutaneous test (PPd and DHT) were performed at baseline and each three months, them screening from active tuberculosis. RESULTS: Study's population was 165 patients and control group was 69. The average age was 26 and 23.8 respectively. The medium follow-up was 25 months. Active tuberculosis was developed in 9.26 cases per one hundred persons and year from follow-up. It was between 4.92 in cases with more than 500 CD4+ lymphocytes and 3.08 for them with lymphocytes between 50 and 200 per mm3. The incidence tests was 3.99 in PPD negative normoergic patients and 15.87 in PPD negative anergic patients. CONCLUSIONS: Risk from active tuberculosis was relactioned with latent infection and immunodeficiency degree. We constated high risk in low CD4+ lymphocytes counts; and degrees from DHT let an approach to tuberculosis production mechanism.
