Abstract
Background
The triple burden of COVID-19, tuberculosis and human immunodeficiency virus is one of the major global health challenges of the 21 st century. In high burden HIV/TB countries, the spread of COVID-19 among people living with HIV is a well-founded concern. A thorough understanding of HIV/TB and COVID-19 pandemics is important as the three diseases interact. This may clarify HIV/TB/COVID-19 as a newly related field and play an important role in the present and future management of the co-infections. However, several gaps are remaining in the knowledge of the burden of COVID-19 on patients with TB and HIV, the diagnosis, and management of these patients.
Objectives
The study was conducted to review different studies on SARS-CoV, MERS-CoV or COVID-19 associated with HIV/TB co-infection or only TB and to understand the interactions between HIV, TB and COVID-19 and its implications on the burden of the COVID-19 among HIV/TB co-infected or TB patients, screening algorithm and clinical management.
Methods
We conducted electronic search of potential eligible studies published in English in the Cochrane Controlled Register of Trials, PubMed, Medrxiv, Google scholar and Clinical Trials Registry databases. We included case studies, case series and observational studies published between January, 2002 and March, 2020 in which SARS-CoV, MERS-CoV and COVID-19 co-infected to HIV/TB or TB were managed in adult patients. We screened titles, abstracts and full articles for eligibility. As we anticipated heterogeneity in the literature, results were reported narratively.
Main results
After removing 69 duplicates, 24 out of 246 articles were assessed for eligibility, of which 9 studies were included for qualitative analysis. Among them, we included two case reports, four case series, one case-control and two retrospective observational studies. The studies have shown that TB may occur during or after SARS-CoV. In terms of severity, the proportion of severe/critical SARS, MERS and COVID cases with TB co-infection was higher than in patients with mild/moderate stages (P= 0.0008).
Conclusion
SARS/MERS-CoV/COVID-19 associated to HIV/TB or TB subjects had a higher risk of developing severe/critical than mild/moderate SARS/MERS-CoV/COVID-19. Diagnostic algorithms and clinical management were suggested for efficiently improving COVID-19/HIV/TB co-infections outcomes.
