Abstract
Talaromycosis marneffei (T.M) is the primary opportunistic infection of AIDS patients, and its morbidity and mortality are extremely high. To further clarify the disease characteristics of patients and provide a solid basis for in-depth exploration of their pathogenic mechanisms, we retrospectively summarized and analyzed their clinical data. We included all T.M patients tested for direct antiglobulin test (DAT) in the study. Interestingly, we found that AIDS-T.M patients had an extremely high rate of DAT positivity (92/127, 72.44%). In univariate analysis, a positive DAT was associated with blood culture of TM (P=.021), hypoproteinemia (P=.001), anemia (P=.001), thrombocytopenia (P=.003), sepsis (P=.007), and Sequential Organ Failure Assessment (SOFA) (P=.001). Hypoproteinemia, anemia, SOFA, APTT>32.6 s, and AST > 40U/l were studied by logistic regression. Logistic regression revealed that SOFA (OR=1.311, P=.043), hypoproteinemia (OR=0.308, P=.021), and anemia (OR=0.19, P=.044) were associated with positive DAT. Positive DAT was associated with severe disease manifestations such as sepsis, and the DAT test is crucial in patients with fungemia.
