Pathological findings in respiratory organs and blood circulation in patients with isolated DRTB and DRTB/HIV/AIDS co-infection (according to autopsy data).

Tuberculosis remains a major global health concern, especially in the context of emerging drug-resistant strains and the high prevalence of HIV/AIDS. Understanding the pathomorphologic changes associated with DRTB and its coinfection with HIV/AIDS is crucial for designing effective diagnostic, preventive, and therapeutic interventions. The objectives of this study were to assess the pathomorphologic changes, investigate lung function and blood circulation, and explore risk factors and clinical predictors associated with cor pulmonale in patients with DRTB and DRTB/HIV/AIDS co-infections.
