Effects of dexamethasone combined with ambroxol hydrochloride on T-Cell subsets and hearing in patients with secretory otitis media

Abstract

The aim of the study was to investigate the effect of dexamethasone combined with ambroxol hydrochloride on T cell subsets and hearing in patients with secretory otitis media. Eighty-six cases of patients with secretory otitis media admitted to “Gansu Provincal Hospital, Lanzhou, China” from September 2016 to September 2018 were regarded as subjects of the study. The patients were divided in two groups according to the digital table method. Among them, the control group was treated with ambroxol hydrochloride, while the study group was treated with dexamethasone combined with ambroxol hydrochloride. The clinical efficacy, T cytokines before and after treatment, auditory threshold and middle ear resonance frequency were observed and compared between the two groups of the patients. SPSS 18.0 software was used to statistically analyze the data. The therapeutic efficacy of the study group was better than that of the control group and the levels of CD4+ , CD4+ /CD8+ after treatment of the study group were higher than that of the control group (P<0.05), while the content of CD8+ in the study group was lower than that in the control group (P<0.05). In addition, the auditory threshold of the study group was lower than that of the control group (P<0.05), whereas the middle ear resonance frequency was higher than that of the control group (P<0.05). The application of dexamethasone combined with ambroxol hydrochloride improved the clinical symptoms and restored hearing in the clinical treatment of patients with secretory otitis media and the therapeutic efficacy was ideal.
