Abstract  Objective To investigate the diagnostic value of serum histone deacetylase 2 (HDAC2) and pulmonary surfactant protein D (SP-D) in the prognosis of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) combined with mild to moderate type Ⅱ respiratory failure treated by nasal high flow oxygen therapy. Methods A total of 312 patients with AECOPD complicated with mild to moderate type Ⅱ respiratory failure admitted to the Department of Respiratory, Hebei Chest Hospital from January 2018 to December 2020 were selected. All patients received conventional treatment and nasal high flow oxygen therapy, and they were divided into stable group (224 cases) and recombination group (88 cases) according to the outcome after 14 days of treatment. General data, serum HDAC2, and SP-D levels before treatment were collected and compared to analyze the prognostic factors of patients with AECOPD complicated with mild to moderate type Ⅱ respiratory failure treated with nasal high flow oxygen therapy. Receiver operating characteristic curve and area under curve (AUC) were used to analyze the diagnostic value of serum HDAC2 and SP-D levels before treatment for prognosis of patients. Results The acute physiology and chronic health evaluationⅡ (APACHE Ⅱ) score, white blood cell count, neutrophil count, C-reactive protein, erythrocyte sedimentation rate, procalcitonin, serum HDAC2 before treatment, and serum SP-D before treatment in the recombination group were higher than those in the stable group, and the differences were statistically significant (P < 0.05). The results of multivariate analysis showed that APACHE Ⅱ score, serum HDAC2 before treatment, and serum SP-D level before treatment were the influencing factors of the prognosis of AECOPD with mild to moderate type Ⅱ respiratory failure after 14 days of nasal high flow oxygen therapy (P < 0.05). Serum HDAC2 and SP-D levels before treatment had certain diagnostic value for the prognosis of AECOPD patients with mild to moderate type Ⅱ respiratory failure after 14 days of nasal high flow oxygen therapy (AUC > 0.5, P < 0.05). Conclusion Serum HDAC2 and SP-D levels are correlated with the prognosis of AECOPD patients with mild to moderate type Ⅱ respiratory failure after 14 days of nasal high flow oxygen therapy, which has certain diagnostic value.
