Objective:

To ascertain clinical, socio-demographic and pharmacological characteristics of patients with pulmonary tuberculosis.

Methodology:

This is a descriptive, retrospective, and cross-sectional study conducted on a sample of 157 patients. Data were extracted from the Secretaría Municipal de Salud Pública database of the city of Cali during 2013. Correlations among variables was identified using the Chi-Square Test of Independence and the IBM spss Statistics 22.0.

Results:

62.4% of the study subjects were young men and 72%, came from low socio-economic levels. 9.2% of patients developed drug-resistant pulmonary tuberculosis (p = 0.0231). Resistance to isoniazid was 94.2%; to rifampicin, 78.8%; to pyrazinamide, 21.2%; to ethambutol, 25%; to streptomycin, 48.1%. Malnourished patients and drug/alcohol addicts were more resistant to antituberculosis therapy. 19.2% of patients were drug-resistant pulmonary tuberculosis and drug/ alcohol addicts; 15.4%, had diabetes; and 13.4%, were co-infected with human immunodeficiency virus (HIV).

Conclusions:

The higher proportion of males with tuberculosis might be influenced by an exposure to the infective agent, since this group is the most working population. A higher prevalence of strains that are multi-drug-resistant to first-line drugs was found in patients from low socioeconomic levels, belonging to marginalized groups, and with risk factors, such as malnutrition, and alcohol/ psychoactive substances abuse.
