ABSTRACT

Objective:To investigate the correlation between serum adiponectin (APN) and inflammatory markers, nutritional status and severe acute exacerbation in late stage in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:One hundred and sixty-three male patients with AECOPD from July 2017 to April 2019 in Wusong Hospital of Baoshan District, Shanghai City were selected. The patients were divided into low APN group (serum APN ≤ 102.38 μg/L, 97 cases) and high APN group (serum APN>102.38 μg/L, 66 cases). The interleukin (IL)-6, IL-8, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), hemoglobin, albumin, prealbumin, body mass index (BMI) and number of severe acute exacerbation in 1 year′ follow-up were compared between 2 groups, and the correlation between APN and inflammatory markers, nutritional status and number of severe acute exacerbation were analyzed.Results:The BMI, hemoglobin, prealbumin and albumin in low APN group were significantly higher than those in high APN group: (23.20 ± 3.26) kg/m 2 vs. (20.77 ± 3.78) kg/m 2, (133.23 ± 17.13) g/L vs. (125.68 ± 20.83) g/L, (185.36 ± 57.60) g/L vs. (148.83 ± 64.79) g/L, (37.09 ± 4.06) g/L vs. (33.77 ± 5.86) g/L, and there were statistical differences ( P<0.01 or<0.05); there were no statistical differences in total protein, IL-6, IL-8, CRP and ESR between 2 groups ( P>0.05). APN showed negative correlation with BMI, hemoglobin, albumin and prealbumin ( r = -0.42, -0.28, -0.33 and -0.31; P<0.01); there was no correlation with IL-6, IL-8, ESR and CRP ( P>0.05). The rate of 4 times of severe acute exacerbation in 1 year′ follow-up in low APN group was significantly lower than that in high APN group: 8.25% (8/97) vs. 22.73% (15/66), and there was statistical difference ( χ2 = 6.79, P<0.05). Conclusions:The AECOPD patients with low APN have better nutritional status and less exacerbation. Serum APN can be used as a predictive index of severe acute exacerbation in AECOPD patients
