Human immunodeficiency virus infection amongst newly diagnosed tuberculosis patients and their clinico-radiological profile: A prospective study from Western India

Abstract

Background: Since time immemorial tuberculosis (TB) has been and continues to be one of the most significant infections causing human disease. In tropical countries, TB remains a leading cause of death. Human immunodeficiency virus (HIV) epidemic continues to fuel this global TB epidemic. The rapid growth of the HIV epidemic in many countries has resulted in an equally dramatic rise in the estimated number of new TB cases, which present therefore the integration of HIV and TB testing at the primary level is need of the hour. Methods: A prospective study was conducted on newly diagnosed, untreated TB patients aged 15-45 year and patients were screened for HIV infection. Clinico-radiological spectrum of TB among HIV seropositive and seronegative patients was evaluated. Results: Out of a total of 307 patients screened, 17 (5.54%) were found to be HIV seropositive. Seroprevalence was found significantly ( P < 0.01, χ 2 9.301) more common in 26-35 year age group and higher in Extrapulmonary TB (EPTB) patients than that in pulmonary TB (PTB) patients (9.90% vs 3.4%). Fever was the most common presenting symptom for TB in HIV seropositive patients. On examination pallor (58.82% vs. 15.86%), oral ulcer (35.3% vs. 0.35%) was found more common and on chest X-ray mid-lower zone involvement and mediastinal lymphadenopathy were more common in HIV seropositive patients. Conclusion: HIV seropositivity rates among newly diagnosed TB patients aged 15-45 year was 5.54 percent. The presentation of TB was more often atypical among these patients. Thus, an integrated model of TB and HIV at primary healthcare service delivery is an efficient use of resources that would address the two very important co-epidemics and thereby result in better management.
