Objective To explore the feasibility and clinical application value of low attenuation areas (LAA) scoring system in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods A total of 380 patients with AECOPD were included. Clinical data including general information, laboratory examinations and treatments during hospitalization were collected. According to the high-resolution computed CT (HRCT) imaging performance, the patients were divided into bronchitis phenotype and emphysema phenotype. The clinical data between these two groups were compared to analyze the differences between different phenotypes and the feasibility of LAA scoring system.Results In patients of bronchitis phenotype, the levels of body mass index, C-reactive protein, interleukin-6, procalcitonin, neutrophil-to-lymphocyte ratio, and eosinophil counts on admission were higher than those of emphysema phenotype (P<0.05). Patients with emphysema phenotype had a higher proportion of male, a higher smoking index, higher cystatin C levels and lower bilirubin levels on admission (P<0.05), the rates of using mechanical ventilation and systemic glucocorticoids were higher as also (P<0.05). LAA scores had a positive correlation with the use of mechanical ventilation and systemic glucocorticoids and cystatin C levels, and a negative correlation with interleukin-6 levels (P<0.05).Conclusions For patients with AECOPD, using LAA scoring system to classify different phenotype through HRCT has relevant accuracy and clinical practicability. The LAA scoring system might help to evaluate the patient's condition and prognosis to a certain extent.
