Observational study reveals high rates of TB hospitalizations in Brazil, indicating links to malnutrition and HIV coinfection.

This research aims to analyze the patterns and causes of tuberculosis-related hospitalizations in Brazil over nine years.
Conducted a retrospective, observational study at a regional referral tertiary public hospital in São Paulo, Brazil.
Reviewed medical records to gather epidemiological, clinical, laboratory, and microbiological data from 2013 to 2022.
Analyzed TB hospitalizations, including patient demographics and comorbid conditions.
Gathered data on diagnostic methods used for TB confirmation.
Among 197 TB hospitalizations, 73.1% were male with a mean age of 41.8 years.
55.3% had TB-HIV coinfection, with 83.5% of these patients having low CD4+ T-cell counts.
Common comorbidities included malnutrition (40.1%), smoking (64.0%), and alcohol use (51.6%).
In-hospital mortality rate was 17.3%, with significant risk factors including malnutrition and thrombocytopenia.
