Abstract:
Objective:To analyze the clinical features of acquired immunodeficiency syndrome (AIDS) patients complicated with peripulmonary occupational lesions.Methods:Fifty-five AIDS patients with peripulmonary occupational lesions treated in Guangzhou Eighth People′s Hospital from January 2012 to January 2019 were included, and the clinical data of patients were retrospectively analyzed. According to the results of lung biopsy, the patients were divided into Mycobacterium infection group, fungal infection group and tumor group. The clinical characteristics, the proportion of different CD4 + T lymphocyte counts and chest computed tomography (CT) features of the three groups were compared. Chi square test was used for comparison among the three groups, and Bonferroni method was used to correct the test level for pairwise comparison. The significance level was 0.016 7 because of three pairwise comparisons. Results:Among 55 AIDS patients complicated with peripulmonary occupational lesions, pulmonary biopsy showed 14 cases with Mycobacterium infection, 12 cases with fungal infection and 15 cases with tumor lesions. Mixed diseases were found in 11 patients, including seven cases with Mycobacterium and fungus coinfection, four with tumor complicated with fungus and (or) Mycobacterium. Three with chronic interstitial pneumonia. The main clinical manifestations of 55 patients were fever, expectoration, fatigue, weight loss and superficial lymph node enlargement. There were no significant differences in symptoms/signs, white blood cell counts, hemoglobin levels, alanine transaminase and creatinine among Mycobacterium infection group, fungal infection group and tumor group (all P>0.05). There was significant difference in anti-retroviral therapy (ART) acceptance among the three groups ( χ2=15.165, P<0.01). However, the results of pairwise comparison between groups showed that there was significant difference between fungal infection group and tumor group ( χ2=7.514, P<0.016 7), while there was no significant difference between Mycobacterium infection group and tumor group, Mycobacterium infection group and fungal infection group ( χ2=0.255 and 5.306, respectively, both P>0.016 7). There were significant differences in clinical outcomes among the three groups ( χ2=15.119, P<0.01), and the pairwise comparison between the Mycobacterium infection group and the tumor group, and the fungal infection group and the tumor group showed significant differences ( χ2 =10.311 and 9.095, respectively, both P<0.016 7). The cases with CD4 + T lymphocyte count ≤50/μL, 51-<200/μL and ≥200/μL in Mycobacterium infection group were three cases, one case and 10 cases, respectively; those in fungal infection group were 10 cases, two cases and 0 case, respectively, and those in tumor group were one case, two cases and 12 cases, respectively. The difference was statistically significant ( χ2=21.284, P<0.01). Chest CT showed that there was significant difference in the types of space occupying lesions among the three groups ( χ2=13.308, P=0.003), and pairwise comparison between the two groups showed that there was significant difference between the Mycobacterium infection group and the tumor group ( χ2=11.312, P<0.016 7), while there were no significant differences between the Mycobacterium infection group and fungal infection group ( χ2=0.931, P>0.016 7), and the fungal infection group and the tumor group ( χ2=7.053, P>0.016 7). There was significant difference among the three groups in calcification focus ( χ2=8.524, P=0.004), while there was no difference between the Mycobacterium infection group and fungal infection+ tumor group ( χ2=10.982, P<0.016 7). Conclusions:Mycobacterium infection, fungal infection and tumor are the main types of peripulmonary occupational lesions in AIDS patients. The differential diagnosis could be made by combining with chest CT features, ART acceptance and CD4 + T lymphocyte level.
