Radiographic Manifestations of Tuberculosis in HIV positive patients: Correlation with CD4+ T-cell count

Abstract Background Observations on Tuberculosis/HIV co-infection in addition to epidemiologic molecular studies have recently provided strong evidence for the state of immune system as the major determinant of the TB imaging spectrum. However, the presence of any correlation between radiographic findings and the degree of immunosuppression in HIV+ patients still remains controversial. The present study aimed to investigate the TB radiographic manifestation in HIV+ patients and its relationship to the CD4 cell count. Method and material Chest radiography of 15 HIV+ patients with a definite diagnosis of pulmonary Tuberculosis in Masih Daneshvari Hospital, between 2013 -2014, were retrospectively reviewed. Radiographic findings and severity were categorized as typical (upper lobe infiltration/cavity) and atypical (middle/lower lobe opacity, adenopathy, pleural effusion and normal X-ray). Demographics and CD4+ cell count were also recorded. Data analysis was performed using SPSS version 23 (frequency and mean for descriptive quantitative variables and Logistic regression analysis for correlation, p
