Abstract:
Objective To analyze the positive rate of serum mycoplasma pneumoniae antibody IgM in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in Liangjiang New Area of Chongqing and the related risk factors, so as to provide a theoretical basis for clinical diagnosis and treatment of AECOPD. Methods Retrospective analysis of 728 cases of AECOPD patients from January 2020 to December 2021 in Chongqing Liangjiang New Area Third Class Hospital. ELISA was used to determine Mycoplasma pneumoniae IgM antibodies. According to the detection of Mycoplasma pneumoniae IgM antibodies, the patients were divided into infection group and non-MP infection group. Clinical data such as gender, age, length of stay, place of residence, smoking status, home oxygen therapy, GOLD grade of COPD, number of acute exacerbations in the previous year, mechanical ventilation, and application of anti-infective drugs were collected. Univariate analysis and logistic regression were used to analyze the risk factors of MP infection in AECOPD patients. Results The positive rate of MP-IgM in 728 AECOPD patients was 15.38% (112/728), including 67 males and 45 females. There was no significant difference in the positive rate of MP-IgM in AECOPD patients between different seasons (χ2=2.840, P>0.05). Age ≥60 (OR=3.243), smoking (OR=2.559) and GOLD grade 3-4 (OR=3.760) were independent risk factors for MP infection in AECOPD patients. Conclusion The incidence of MP infection in AECOPD patients in Liangjiang New Area of Chongqing is relatively high, especially in AECOPD patients with age ≥ 60, smoking, GOLD grade 3-4, which should be warned of the possibility of mycoplasma pneumoniae infection , and targeted treatment measures can improve the cure rate.
