摘要

Objective. To assess the radiographic features in patients with Human Immunodeficiency Virus (HIV) complicated by pulmonary tuberculosis (PTB), and the association with CD4 lymphocyte count and sputum smear. Method. A prospective study was carried out on 89 HIV positive patients with PTB. The demographics, smoking history, sputum smear result, chest radiographic findings and CD4 lymphocyte count were documented. Results. Out of the 89 patients recruited in the study, 41 were males and 48 were females. Eighteen (18) patients had typical radiographic features, 60 patients had atypical radiographic features while only 11 of them had normal radiographic films. Sixty eight (68) patients had CD4 count <200 cells/mm3, 19 patients had CD4 count between 200–499 cells/mm3, while only 2 patients had CD4 count from 500 cells/mm3 upwards. The association between low CD4 count and radiographic finding was statistically significant, (P value <0.05). Sixty (60) patients had negative sputum smear for Acid and Alcohol Fast Bacilli (AAFB), while the remaining 29 patients had positive smear. The association between low CD4 count and negative smear was statistically significant (P value <0.05). Conclusion. The radiographic pattern and the result of the sputum smear for AAFB has a significant relationship and association with the immune status of patients with Human Immunodeficiency Virus (HIV) complicated by pulmonary tuberculosis.
