    Abstract:

    ObjectiveTo evaluate the effect of galactomannan(GM) test combined with CD4+ T lymphocyte detection on early diagnosis of invasive aspergillosis (IA) in patients with acquired immunodeficiency syndrome (AIDS).Methods197 AIDS patients who were suspected with IA in a hospital from January 2014 to December 2016 were analyzed retrospectively, they were divided into confirmed IA group (n=35), clinically diagnosed IA group (n=96, suspected cases), and nonIA group(n=66), sensitivity and specificity of GM test and GM test combined CD4+T lymphocyte counting for diagnosing IA were compared.ResultsIn confirmed IA group, clinically diagnosed IA group, and nonIA group, the medium values of GM (minimum, maximum) were 1.29(0.65,1.84)pg /mL, 0.91(0.36,1.23)pg /mL, and 0.11(0.28,0.72)pg /mL respectively, CD4+T lymphocyte counting were 45(29,69)cells/μL, 79(35,99)cells/μL, and 89(59,158)cells/μL respectively, GM value and CD4+T lymphocyte counting among three groups were significantly different(all P<0.05). The sensitivity and specificity of single GM test for diagnosing IA in AIDS patients were 64.9% and 72.7% respectively; sensitivity and specificity of two consecutive GM test within one week for diagnosing IA were 72.5% and 95.5% respectively; sensitivity and specificity of GM test combined CD4+T lymphocyte counting were 86.3% and 90.9% respectively.ConclusionGM test has better diagnostic value for IA in AIDS patients, continuous GM test and GM test combined CD4+ T lymphocyte counting will further improve the clinical diagnostic value for IA.
