Abstract:

Objective To investigate the influence of obesity/overweight on T helper(Th) 1 cell inflammatory factor [tumor necrosis factor-alpha(TNF-α)],Th2 cell inflammatory factors [interleukin(IL)-10,IL-13],Th17 cell inflammatory factor(IL-17F) and regulatory T cell(Treg) inflammatory factor(IL-35) at attack stage of asthma children in peripheral blood. Methods A total of 112 children with asthma at Shanghai Pudong New Area People's Hospital from January 2020 to December 2021 were enrolled and classified into asthma group(56 cases),obesity/overweight combined asthma group(56 cases) according to body mass index(BMI),and 56 non-asthma children with obesity/overweight(obesity/overweight group) were enrolled. The levels of TNF-α,IL-10,IL-13,IL-17F,IL-35,IL-6 and leptin in peripheral blood were determined. The correlation between BMI and indexes was evaluated by Spearman correlation. Results There was statistical significance in serum levels of IL-6,IL-10,IL-13 and leptin in asthma group,obesity/overweight combined asthma group and obesity/overweight group(P<0.05). The serum TNF-α level in obesity/overweight combined asthma group was higher than that in asthma group(P<0.05). The serum IL-17F level in obesity/overweight group was higher than those in asthma group and obesity/overweight combined asthma group(P<0.05). IL-35 in asthma group was higher than those in obesity/overweight combined asthma group and obesity/overweight group(P<0.05). The obesity/overweight combined asthma group and obesity/overweight group were further classified into overweight combined asthma group,obesity combined asthma group,overweight group and obesity group. BMI was positively correlated with IL-6 in overweight combined asthma group,obesity combined asthma group,overweight group and obesity group by Spearman correlation(r=0.515,0.510,0.515 and 0.432,P<0.05). BMI was positively correlated with leptin(r=0.488,0.578 and 0.546,P<0.05) and negatively correlated with IL-35(r=-0.491,-0.517 and -0.524,P<0.01). Conclusions Obesity/overweight can cause the imbalance of Th1/Th2 expression. Th1 cell inflammatory factors are mainly expressed in children with obesity/ overweight combined asthma.
