الوصف: | Combination of bronchial asthma (BA) and obesity is a difficult-to-control phenotype. Studies of inflammatory process with respect to severity of the disease are important for understanding the potential influence of obesity on the BA clinical course. The objective of this study was to determine cytokine profile in patients with mild BA combined with obesity. The study involved fifty-three patients with partially controlled mild BA. The patients were recruited as volunteers and signed an informed consent. The first observation group consisted of 27 asthma patients with normal body weight, the second observation group consisted of 26 patients with BA combined with obesity. A control group included 25 healthy volunteers. All the patients underwent clinical and laboratory examination in accordance with clinical standards for BA and obesity. The levels of TNFα, IL-2, IL-4, IL-6, IL-10 were evaluated in blood serum by means of flow cytometry. The ratios of proand anti-inflammatory cytokines (TNFα/IL-4, TNFα/IL-10, IL-6/IL-4, IL-6/IL-10) were calculated. Asthma patients with obesity (the 2nd group) had elevated levels of IL-2 over control group and group 1, by 38% and 44% respectively(p < 0.05). The concentration of proinflammatory cytokines TNFα and IL-6 was significanty increased in the both patient groups. Mean TNFα level was increased 2.5 times (p < 0.05), and IL-6 levels were increased by 30% (p < 0.05) in the 1st group as compared to the controls. TNFα and IL-6 concentrations showed a 3-fold increase over control values (p < 0.05) in the 2nd group. The level of antiinflammatory cytokine IL-4 was increased in patients with BA, independently of body mass. It should be noted that the concentration of this cytokine in obese patients was higher by 29% than in patients with normal body weight. IL-10 levels in patients from the 2nd group were reduced more than 2 times than in the 1st group. The patients of the 1st group showed a decrease in the IL-6/IL-10 index, in comparison with control parameters, thus indicative of an imbalance due to the elevation of the anti-inflammatory IL-10 cytokine. Among BA patients with obesity (group 2) the TNFα/IL-10 and IL-6/IL-10 indexes were higher than those of the control group (2.3- and 5.5-fold, respectively) and the group 1 (2.6- and 2.5-fold, respectively). Dynamics of these indexes confirms the systemic nature of inflammation and a predominance of non-atopic inflammation in asthma patients with obesity. Thus, features of the cytokine profile in BA with obesity consist of a significant increase in pro-inflammatory IL-2, IL-6, TNFα cytokines, and a relative decrease in anti-inflammatory IL- 10 cytokine. The development of BA with obesity, even in mild-severity BA, is accompanied by development of a cytokine disbalance, which is typical for a mixed-type inflammation, with a prevalence of neutrophil inflammation. |
