Asthma is a common respiratory disease. Theophylline combined with inhaled corticosteroids (ICS) is a promising therapy for asthma. This study explored the therapeutic effects of ICS combined with theophylline on moderate and severe asthma patients and T lymphocyte subsets (CD3+CD8+ T cells) in peripheral blood.

Material and methods:
A total of 202 moderate and severe asthma patients were selected, with 101 treated with theophylline combined with ICS and 101 treated with ICS alone as controls. Lung function [forced expiratory volume within 1 second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF)] were tested using a spirometer. Asthma symptom control was evaluated by asthma control tests (ACT). The life quality was evaluated using the Asthma Quality of Life Questionnaire (AQLQ). The number and percentage of CD3+ T, CD3+CD4+ T and CD3+CD8+ T cells in peripheral blood mononuclear cells were assessed by flow cytometry. The correlation between CD3+CD8+ T cells and lung function and asthma control of patients after combination therapy was analyzed by Pearson correlation analysis.

Compared with moderate and severe patients treated with ICS alone, theophylline improved the efficacy of ICS. Theophylline combined with ICS decreased IL-4 and IL-6 levels, and CD3+ T and CD3+CD8+ T cell number and percentage. After combined treatment, CD3+ CD8+ T cells in peripheral blood of patients were positively correlated with lung function and negatively correlated with asthma control.

The additional use of theophylline improved the efficacy of corticosteroids in asthma patient treatment and reduced inflammation level and CD3+ T and CD3+CD8+ T cell contents in peripheral blood.
