Objective Allergic bronchopulmonary aspergillosis (ABPA) is characterized by anexaggerated reaction to airway colonization aspergillus which affects patients with underlying diseases such asbronchial asthma, cystic fibrosis or other respiratory diseases. ABPA exhibit significant heterogeneity due to theunderlying diseases. The clinical features of patients with ABPA were analyzed retrospectively, so as to explore theimpact of underlying diseases on clinical characteristics. Methods The clinical data of hospitalized patients diagnosed with ABPA from January 2010 to September 2019 in Peking University People's Hospital were reviewed for retrospective analysis. Results A total of 40 ABPA patients were enrolled. Of which 8 cases (20.0%) were previously diagnosed as chronic obstructive pulmonary disease and/or bronchiectasis, named non-asthma group; while the other 32 cases met the diagnosis criteria of asthma, named asthma group. The non-asthma ABPA patients had a shorter course [78 (6 - 300) months vs. 192 (39 - 480) months, P=0.02], a higher percentage of peripheral blood neutrophils (79.9%±12.5% vs. 68.1%±18.1%, P=0.01) and higher score of emphysema [2 (0 - 2) vs. 0 (0 - 1), P=0.02] than the asthma group. Conclusions There is no significant difference in clinical and radiological characteristics between ABPA patients without asthma and those with asthma. The diagnosis of ABPA should also be considered when patients with chronic pulmonary diseases such as chronic obstructive pulmonary disease and bronchiectasis have aggravation of dyspnea, increase of eosinophils in peripheral blood and typical imaging features such as mucus attenuation.
ObjectiveTo explored the influence of disease changes, weight gain, eosinophil levels and other factor in pregnancy women with asthma. MethodsCase records of gestational asthma patients produced in the obstetrics department of Peking University People's Hospital from October 2010 to October 2020 were collected, and refer to electronic medical records of clinics (pre-pregnancy and pregnancy). According to the disease control (asthma related unplanned respiratory clinics, emergency or hospitalization), patients were divided into pregnancy stable group and pregnancy fluctuation group. The basic characteristics, pre-pregnancy asthma control, weight gain during pregnancy and peripheral blood eosinophil level before labor were retrospectively analyzed. The cause of asthma attacks, clinical characteristics and distribution of gestational time in pregnancy fluctuations were described. Peripheral blood eosinophil levels in different period during pregnancy in the stable group were analyzed. ResultsTotally 124 cases of natural pregnancy singleton were enrolled in the study. The age was (32.3±3.9) years old. There were 71 patients in stable group and 53 patients in fluctuation group. The proportion of pre-pregnancy instability in the fluctuating pregnancy group was higher than that in the stable pregnancy group (P<0.05). The proportion of intermittent medication before pregnancy was higher in the fluctuating pregnancy group than in the stable pregnancy group (P<0.05). Peripheral blood eosinophil count before labor and the number of cases with eosinophil count≥0.15×109/L before labor were higher in the fluctuation group (all P<0.05). The proportion of hypertentive diseases in pregnancy and fetal distress in uterus were higher in the fluctuation group (all P<0.05). The common cold was the common trigger factor (38.2%) and asthma recurrences occur between 13 and 36 weeks of gestation (65.8%) in fluctuation group. In further analysis of subgroup (the stable group), peripheral blood eosinophil count in early pregnancy (P<0.05) and pregnant metaphase (P<0.05) were higher than before delivery. The number of cases with eosinophil count>0.15×109/L in pregnant metaphase (P<0.05) was higher than before delivery. ConclusionsAsthma fluctuates during pregnancy is associated with adverse maternal and fetal outcomes. It is very important and critical that asthma control before pregnancy, weight gain management and eosinophil level monitoring of patients with asthma during pregnancy. The whole management is imperative in women with asthma during pregnancy.
