Abstract

Objectives: To determine the factors associated with Mycobacterium tuberculosis complex-positive blood culture.

Methods: Case-control study. Sociodemographic, clinical and laboratory data were collected from 2000 to 2015.

Results: We reviewed medical records of 533 patients with culture-proven tuberculosis, of whom 27.2% (145/533) had blood culture available. Patients with mycobacteremia presented more frequently with abdominal tuberculosis, body mass index <18kg/m2, and had lower hemoglobin and albumin levels. No differences were observed regarding HIV status.

Conclusions: Few studies have reported on the characteristics associated with Mycobacterium tuberculosis complex bacteremia, especially among Human Immunodeficiency Virus-negative patients. Out of 145 tuberculosis-infected patients with blood culture results available, 21 turned out positive. Anemia, hypoalbuminemia, and a body mass index<18kg/m2 were associated with mycobacteremia.

Keywords: Bloodstream infection; Case-control study; Human immunodeficiency virus; Mycobacteremia; Mycobacterium tuberculosis.
