Objective: To investigate the correlation between the serum hypoxia-inducible factor-1α, uric acid, inflammatory factor levels, and lung function in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).
Methods: The clinical data of patients with chronic obstructive pulmonary disease (40 cases) from March 2020 to March 2021 were retrospectively analyzed. According to the disease condition in patients with chronic obstructive pulmonary disease, they were divided into acute exacerbation stage (observation group, 20 cases) and stable stage (control group, 20 cases). All patients' basic data such as age, sex, and course of disease were collected and sorted out, and the serum hypoxia-inducible factor-1α, uric acid, inflammatory factor levels (procalcitonin, interleukin-6, and high-sensitivity C-reactive protein), and the index of their pulmonary function were measured. The profiles of serum hypoxia-inducible factor-1 alpha and uric acid, levels of inflammatory factors, and pulmonary function indices were measured and compared between the observation and control groups. The correlation between patients' serum hypoxia-inducible factor-1α, uric acid, and inflammatory factors and lung function was analyzed.
Results: There was no difference in basic data between the observation group and the control group, P > .05. Serum hypoxia-inducible factor-1α, uric acid, and levels of inflammatory factors were all higher in the observation group than the control group, and the differences are significant (P < .05). There was significant difference in lung function indexes between the observation group and the control group (P < .05). Serum hypoxia-inducible factor-1α, uric acid, and inflammatory factor levels were negatively associated with pulmonary function indices.
Conclusion: The more serious the condition of AECOPD patients is, the levels of serum hypoxia inducible factor -1α, uric acid and inflammatory factors gradually increase, and the lung function tends to decline.
