摘要: 目的 动态分析侵袭性肺曲霉菌病(IPA)患者治疗前后半乳甘露聚糖(GM)和(1,3)-β-D-葡聚糖(BG)水平变化。方法 选取确诊或临床诊断的IPA患者63例,分别于治疗前、治疗1个月、治疗3个月进行外周血GM、BG和淋巴细胞亚群检测。根据是否感染人类免疫缺陷病毒(HIV)分为HIV组(40例)和非HIV组(23例);根据不同CD4+T细胞水平分为A组(CD4+T细胞<200 个/μL)、B组(CD4+T细胞为200~500 个/μL)和C组(CD4+T细胞>500 个/μL)。比较各组BG、GM、CD3+T细胞、CD4+T细胞、CD8+T细胞、CD4/CD8比值差异。结果 63例IPA患者治疗3个月GM、BG均低于治疗前、治疗1个月(P<0.05)。HIV组治疗3个月GM、BG均低于治疗前(P<0.05),非HIV组治疗3个月GM低于治疗前(P<0.05)。不同CD4+T细胞水平组中,A组、B组治疗3个月GM水平与治疗前、治疗1个月比较,差异均有统计学意义(P<0.05); A组治疗3个月与治疗前比较,BG差异有统计学意义(P<0.05);C组治疗前、治疗1个月GM低于B组同一治疗期(P<0.05)。结论 IPA患者抗真菌治疗后,GM和BG 2项指标联合检测在IPA的诊断及疗效监测中有一定的临床意义。

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.
