Influence of budesonide∕formoterol fumarate dihydrate and acetylcysteine granules on pulmonary function and immune indices in patients with acute exacerbation of chronic obstructive pulmonary disease
Objective explore the impact of budesonide∕formoterol fumarate dihydrate inhalation combined with acetylcysteine granules on pulmonary function and immune indices in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Methods A cohort of 106 AECOPD patients treated at Funan County People's Hospital from March 2022 to December 2023 was selected and randomized into a control group(n=53)and a combination therapy group(n=53).Both groups received conventional symptomatic treatment;the control group was treated with budesonide∕formoterol fumarate dihydrate inhalation,while the combination group received acetylcysteine granules in addition to the conventional treatment.Lung function,immune indices,inflammatory factors,clinical efficacy,and the incidence of adverse reactions were compared between the two groups.Results Post-treatment,the combination group demonstrated higher forced vital capacity(FVC),forced expiratory volume in one second(FEV1),and FEV1∕FVC ratios compared to the control group(P<0.05).Immune indices post-treatment,including CD4+and CD4+∕CD8+ratios,were higher in the combination group than in the control group(P<0.05),while CD8+levels were lower(P<0.05).Levels of IL-6,IL-8,and TNF-β were reduced in the combination group compared to the control group(P<0.05).The total effective rate was significantly higher in the combination group(94.34%,50∕53)than in the control group(81.13%,43∕53)(χ2=4.296,P<0.05).The incidence of adverse reactions did not differ significantly between the two groups(P>0.05).Conclusion The combination therapy of budesonide∕formoterol fumarate dihydrate inhalation and acetylcysteine granules can improve pulmonary function and immune indices in AECOPD patients,with significant effects on reducing inflammation and improving clinical symptoms,suggesting its potential for broad application.
