Abstract

Background/objectives: Tuberculosis (TB) remains a major global health issue, further complicated by the COVID-19 pandemic. This study assesses the clinical outcomes of TB-COVID-19-coinfected patients compared to those with TB disease alone at an Italian infectious disease hospital during the pandemic's first two years.

Methods: Retrospective data analysis was conducted on TB patients hospitalized from March 2020 to June 2022. Data included demographics, comorbidities, clinical characteristics, and outcomes. Coinfection was defined as concurrent TB disease and SARS-CoV-2 infection. Statistical methods included Fisher's exact test and Mann-Whitney statistics.

Results: Of 267 TB patients, 25 (9.4%) had concurrent COVID-19 infection. The TB-COVID-19 group showed higher rates of diabetes and cough. Acute respiratory failure was more prevalent in coinfected patients (odds ratio, 5.99), and coinfection was associated with worse outcomes compared to TB alone (odds ratio, 0.15). Despite similar socio-demographic factors, the coexistence of TB and COVID-19 led to exacerbated respiratory failure and increased mortality.

Conclusions: Coinfection with TB and COVID-19 significantly increases the risk of acute respiratory failure and poor outcomes. Clinicians should be aware of this risk, especially in patients with pulmonary involvement. Although specific protocols are unavailable, prompt diagnosis and management may enhance outcomes. Additional research is necessary to understand the long-term effects of TB-COVID-19 coinfection, particularly as COVID-19 becomes endemic.
