Abstract

The objective: to identify clinical factors with the highest sensitivity and specificity associated with an unfavorable outcome in the patient with tuberculosis and HIV infection. Subjects. 363 patients with TB/HIV co-infection. Group 1 – 59 (16.3%) patients with the unfavorable outcome, Group 2 – 304 (83.7%) patients with a favorable outcome. Methods: analysis of paired contingency tables by Pearson criterion, quantitative signs by Mann – Whitney test, simple and multiple logistic regression. Results. The following factors promoting unfavorable outcomes in the patient with TB/HIV co-infection with the highest sensitivity and specificity were identified: hemoglobin level (sensitivity – 78.0%; specificity – 73.7%), gastrointestinal candidiasis (72.9% and 84.5%), loose stool (40.7% and 97.4%), no lymphadenopathy (89.8% and 57.2%), and headache (49.2% and 88.5%). The combination of these clinical manifestations provides sensitivity of 78.0% and specificity of 94.4%. A formula is proposed for calculating the probability of an unfavorable outcome in the patient TB/HIV co-infection.
