Objective:
To determine the clinical manifestations of the relapse of the tuberculosis (TB) in the patients infected by the human immunodeficiency virus (HIV) and the degree of immunodeficiency shown.
Material And Method:
They are analyzed retrospectively 121 cases, all they HIV+, diagnosed of TB from November of 1985 until December of 1999. All they fulfilled correctly the specific treatment of the tuberculosis.
Results:
Of 121 studied cases, a total of 13 (10.7%) presented relapse of tuberculosis finally of a mean of 31.8 months (range 1-95). In 7 cases the affectation was pulmonary (2 typical, 5 non typical), in 3 mixed (pulmonary and extrapulmonary) and in 3 extrapulmonary. The clinical sintomatology were present in 92% of the cases and, predominantly, was: fever (92%), cough (69%), sweating, weight loss (61%). Hepatomegaly results be the exploratory finding quite frequent (54%). The mean of CD4+ lymphocytes was 141.7 (range 3-406), in 8 (61%) the lymphocyte counts was inferior to 100 cells/mm3. PPD was positive in 1 case (14%) and with respect to delayed-type hypersensitivity reaction test, it was observed not normoergia in all the cases (100%).
Conclusions:
Relapse of the tuberculosis in patient infected by the VIH is presented with a manifested clinical expresivity in the course of a severe degree of immunodeficiency. In certain groups of risk as the intravenous drugs users, it must of be had a high level of suspicion of the relapse of the disease, above all in those patients that show low CD4+ lymphocyte counts.

Pulmonary Tuberculosis I
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.
