CYTOKINE PROFILE FEATURES IN THE PATIENTS WITH NONALLERGIC BRONCHIAL ASTHMA WITH CO-EXISTING TYPE 2 DIABETES MELLITUS

Abstract

Thirty-five patients with non-allergic bronchial asthma (NABA), 22 patients with NABA and diabetes mellitus type 2 (DT2), 23 subjects with DT2, and 31 healthy controls were enrolled into the study. ELISA assays for IL-4, IL-10, IL-6, IFNγ were performed by means of a standardized protocol using immunoassay kits purchased from VectorBest, and Cytokine. In asthma patients complicated by DT2, the pattern of bronchial asthma was ascribed to NABA. This finding may be consistent with a theory of specific insulin-receptor interactions in asthma. The NABA patients with type 2 diabetes mellitus exhibited a significant increase in IL-6, IFNγ, and decrease of IL-4, as compared with healthy controls and NABA. Moreover, we have revealed an increase of IL-4, IL-6, IFNγ, when compared with DT2. Hence, the patients with coexistence of non-allergic bronchial asthma and DT2 were characterized by a specific cytokine profile of pro- and anti-inflammatory cytokines, which may correlate with increased glycation and deterioration of lung function.
