Introduction: Human immunodeficiency virus (HIV)-associated tuberculosis (TB) remains an important health challenge worldwide.Although TB prevalence has decreased in the general population, there is limited information regarding temporal trends in the incidence of HIV-associated TB in Hong Kong.There are also insufficient data regarding changes in clinical manifestation patterns among HIV-associated TB patients over time.This study aimed to describe temporal trends in the epidemiology and clinical manifestations of HIVassociated TB in Hong Kong. Methods:We retrospectively reviewed data regarding HIV-associated TB patients that were reported to the TB-HIV Registry of the Department of Health during the period 2007 to 2020.Trends of TB as a primary acquired immunodeficiency syndrome (AIDS)-defining illness, as well as changes in demographic features and clinical manifestations of HIV-associated TB during this period were examined using Cochran-Armitage trend test.Results: A decreasing trend was observed in the proportion of all reported cases of AIDS in which TB was a primary AIDS-defining illness during the study period.The proportions of female patients and patients with extrapulmonary involvement significantly increased, whereas the proportions of ever-smokers and patients with sputum smear positivity significantly decreased during the same period.A decreasing trend was observed in the proportion of patients with pulmonary TB in which the lower zone was the predominant site of lung parenchymal lesions.Among patients with a
