HIV-TB co-infection with clinical presentation, diagnosis, treatment, outcome and its relation to CD4 count, a cross-sectional study in a tertiary care hospital in coastal Karnataka.

INTRODUCTION

Tuberculosis (TB) is the leading killer and the commonest opportunistic infection (OI) in human immunodeficiency virus (HIV) infected individuals with 0.3 million deaths in 2017. When HIV and TB co-infection occurs, they form a deadly combination with each accelerating the progression of the other, resulting in increased morbidity and mortality.

AIM AND

OBJECTIVES

To study the demographic pattern, clinical presentation, opportunistic infections, radiological and laboratory profile, management, and outcome of HIV-TB coinfected individuals.

MATERIALS AND

METHODS

A prospective cross-sectional study was carried out on confirmed HIV cases already diagnosed with TB and those newly detected with TB after admission, where diagnosis was carried out following standard operative procedures.

RESULTS

In our study of 58 HIV-TB co-infected individuals, 40-50 years was the most common age group affected. Males were affected more with majority being married. The most common presentation was fever (67%) followed by gastrointestinal symptoms. Majority of TB cases were newly diagnosed (65.5%), with predominance of pulmonary tuberculosis (PTB) (n = 35) followed by those having only extrapulmonary tuberculosis (EPTB) (n = 12) and both (n = 11). TB was diagnosed by microscopy in 32.7%, while radiologically, chest X-ray was most common (36.2%). Also, 50% were infected with other OIs where oral candidiasis was the most common (37.93%). The overall mean CD4 count was 220 cells/μL and those with EPTB had lesser CD4 counts than those with PTB. All were on DOTS regimen and majority showed improvement.

CONCLUSION

In a country like India where both these diseases are rampant, we recommend better information, education, understanding and awareness for prevention, care, early diagnosis, and treatment of these two notorious infectious diseases with prevention of relapse and default of TB cases in HIV-TB co-infected individuals a priority.
