MONTUFAR ANDRADE, Franco E  and  GRUPO DE INVESTIGACION EN ENFERMEDADES RESPIRATORIAS E INFECCIOSAS et al. Co-infection with human immunodeficiency virus and mycobacteria in a tertiary referral hospital in Colombia . Infect. [online]. 2016, vol.20, n.3, pp.158-164. ISSN 0123-9392.

Background: Co-infection with the human inmunodeficiency virus (HIV) and mycobacteria hasa synergistic effect; the risk of extrapulmonary and disseminated mycobacterium disease isincreased and the progression of HIV disease is accelerated. Tuberculosis (TB) is the entity thatis most life threatening to these patients. Methodology: Observational, descriptive and retrospective study. Objective: To determine the epidemiological and clinical characteristics and the resistanceprofile in patients coinfected with HIV and mycobacteria. Results: Of 159 patients diagnosed with HIV, 44 (27.7%) patients were co-infected with myco-bacteria. The average age was 36.7 years ± 11.3. Some 86% were men. At admission, 66% hadacquired immune deficiency syndrome (AIDS), 20% a history of TB and 11% a history of othersexually transmitted diseases. A total of 50% reported a count of CD4 lymphocytes less than50 cells/mm 3 . Major comorbidities were haematological malignancies in 11%, heart failure in4.5%, and lymphoproliferative disease in 4.5%. The annual incidence was 4.6%. Disseminatedforms were found in 54% of cases. M. tuberculosis was identified in 77.3%, non-tuberculousmycobacteria (NTM) in 18.3% and in 4.5%, it was not possible to establish the species. Some2.5% of isolates of M. tuberculosis were multidrug-resistant (MDR-TB) and 18.2% were resistantto a single drug or had combined resistance. There was documented pulmonary involvement In54% of patients. Mortality was 9.1%. Conclusion: In our patients, infection with M. tuberculosis was the most common and the highprevalence of resistance to at least one drug and MDR-TB was striking. NTM infections are becoming more common. The extra-pulmonary and disseminated forms are common, and annual incidence is high.
