RESUMEN
INTRODUCTION: In a historical era dominated by the SARS-CoV-2 pandemic, a fact of growing interest emerges regarding co-infection with Mycobacterium tuberculosis (M. tuberculosis). This represents today an important clinical and diagnostic challenge, as the two pathogens are capable, through specific immunopathological mechanisms, of interacting with each other, determining a severe respiratory condition with a severe prognosis. AREAS COVERED: With this review, we wanted to collect and analyze the latest scientific evidence concerning the main immunopathogenetic mechanisms shared by these two respiratory pathogens, with particular interest in the possible iatrogenic factors favoring coinfection and the need to define multidisciplinary and standardized screening tools aimed to identify coinfection early, ensuring the best clinical and therapeutic management. EXPERT OPINION: The existence of a direct immunopathogenetic link between COVID-19 and TB indirectly contributes to mutual morbidity and mortality. The identification and application of early and standardized screening tools aimed at the identification of this condition is essential, in addition to vaccine prevention.
