| Summary: | Comprehensive morphological examination of surgical and biopsy samples from 148 patients and autopsy specimens from 181 deceased persons was made to determine a correlation between the level of immunosuppression and the microscopic signs of tuberculosis in patients with HIV-associated tuberculosis (HIV/TB). A relation was found between the count of CD4+ lymphocytes and the predominant type of a tissue inflammatory reaction. Insidious granulomatous inflammation and a preponderance of alterative and exudative components in the foci of tuberculous inflammation suggested that a delayed-type hypersensitivity response that was typical of tuberculosis gave way to an immediate-type hypersensitivity response and reflected severe immune system dysfunction. The lack of responsiveness of the macroorganism in the virtually complete absence of CD4+ lymphocytes observed during autopsy examination led to the acute progression and generalization of tuberculosis, by affecting all organs and systems. |
