ABSTRACT
Objective:
To investigate the clinical characteristics and risk factors of bronchiolitis obliterans (BO) after adenovirus pneumonia.Methods:
Clinical data of 266 children with adenovirus pneumonia hospitalized in Children′s Hospital of Soochow University from January 2011 to December 2017 were retrospectively analyzed.Accor-ding to whether they developed BO, children with adenovirus pneumonia were divided into the BO group and the non-BO group.Clinical features of the BO group and the non-BO group were compared by t test, rank sum test or chi square test.Risk factors were analyzed by Logistic regression approach.Results:
Among 266 children with adenovirus pneumonia included, 37 patients were developed into BO group, and their age was significantly younger than that of the non-BO group [12.0(8.0, 17.5) months vs.32.0(13.0, 48.0) months, P<0.001]. Compared with the non-BO group, there were more proportion of preterm infants[10.8%(4/37 cases) vs.3.1%(7/229 cases), P=0.028], more instances of comorbidities [21.6%(8/37 cases) vs.4.4%(10/229), P<0.001] and more children with allergic diseas[35.1%(13/37 cases) vs.20.1%(46/229 cases), P=0.041] in the BO group, and the difference was statistically significant.The duration of fever in the BO group was significantly longer than that of the non-BO group [10(4.0, 13.5) d vs.6(4.0, 9.0) d, P=0.011] children with symptoms of wheezing, shortness of breath, and hypoxemia in the BO group were significantly more than the non-BO group[81.1%(30/37 cases) vs.27.9%(64/229 cases), P<0.001; 64.9%(24/37 cases) vs.5.7%(13/229 cases), P<0.001; 59.5%(22/37 cases) vs.6.6%(15/229 cases), P<0.001]. The platelet count, IgG level, and CD3 -CD 19+ lymphocyte percentage were significantly higher in the BO group than the non-BO group [(364±104)×10 9/L vs.(297±105)×10 9/L, P=0.001; 6.74(4.92, 10.16) g/L vs.5.93(1.00, 8.04) g/L, P=0.016; (33.5±15.3)% vs.(26.1±10.2)%, P=0.008]. In contrast, the percentage of CD3 + CD4 + lymphocytes in the BO group was lower than the non-BO group[(29.1±8.0)% vs.(32.5±9.4)%, P=0.044], the difference was statistically significant.The BO group had a higher rate of mixed bacterial infection than the non-BO groups[37.8%(14/37 cases) vs.16.6%(38/229 cases), P=0.003]. An age<26 months, comorbidities, premature birth history, wheezing, shortness of breath, and hypoxemia were independent risk factors for BO after adenovirus pneumonia( OR=4.808, 30.667, 7.558, 3.909, 8.842, 8.607, all P<0.05).Conclusions:
An age of less than 26 months, a history of premature delivery comorbidities, wheezing, shortness of breath and hypoxemia, are independent risk factors for BO after adenovirus pneumonia.Children with above manifestations should receive high resolution CT as soon as possible to determine whether it is BO.
