Abstract: Objective To analyze dynamically the changes of blood galactomannan(GM) and (1,3)-D-glucan(BG) levels in patients with invasive pulmonary aspergillosis(IPA) before and after treatment. Methods A total of 63 IPA patients with confirmed or clinical diagnosis were enrolled,and their peripheral blood GM and BG determinations and lymphocyte subset determinations were performed before treatment,1 month after treatment and 3 months after treatment. According to whether infected human immunodeficiency virus(HIV) (40 cases of HIV group and 23 cases of non-HIV group)or not and different CD4+ T cell levels(CD4+ T cell count<200 cells/μL in Group A,CD4+ T cell count 200-500 cells/μL in Group B,CD4+ T cell count >500 cells/μL in Group C). The difference of BG,GM,CD3+,CD4+ and CD8+ T cells,CD4/CD8 was evaluated. Results GM and BG levels of 63 patients with IPA in 3 months after treatment were lower than those before treatment and in 1 month after trearment(P<0.05). In HIV group,GM and BG levels were lower in 3 months after treatment than before treatment(P<0.05),whereas in non-HIV group,GM levels were lower in 3 months after treatment than before treatment(P<0.05). According to the classification of CD4+ T cells,the GM levels in Group A and Group B were lower than those before treatment and in 1 month after treatment and in 1 month after treatment(P<0.05),and BG in Group A was lower in 3 months after treatment than before treatment(P<0.05). The level of GM in Group C was lower than that in Group B before treatment and in 1 month after treatment(P<0.05). Conclusions The combined determination of GM and BG plays a role for the diagnosis and antifungal treatment of IPA patients.
