Background and Aim: Plasma leptin, adiponectin (as theadipokines) and related obesity – HOMA index in the obese men are introduced as a predictive metabolic indicators for asthmatic individuals. However, under asthma conditions, role of cariometabolic variables interaction for altering clinical pulmonary indexes aren't clear. In the present study, the relationship between plasmatic adiponectin to leptin ratio (adipo/lep) with respiratory capacities & HOMA in the chronic asthmatic males are investigated.

Materials and Methods: Thirty nine obese males with mild to moderate asthma with an average age of 38±2.6 ys and BMI 31.4 ± 1.06 kg/m² voluntarly participated in this study. Baseline plasmatic leptin, adiponetin, insulin and glucose levels were determined after 10-12 hours fasting overnight. FEV₁/FVC, PEF% and FEF _25%-75% were determined by standard method. A pearson correlation test was used to analyse data.

Results: There were no significant correlation between WHR , BMI with metabolic risk factors (P>0.05). Relationship markedly observed among HOMA with adipo/ lep ratio and leptin levels respectively (P<0.05), Also a marked negative correlation between adipokine ratio and leptin level was obtained (P<0.05). From view of respiratory efficiency, FVC% and FEV₁/ FVC were maingly corrected with baseline leptin&adiponectin levels (P<0.05).

Conclusion: Inconclusion,it seems that adipo/lep ratio biomarker plays as a clinical diagnosis index for HOMA index than baseline leptin or adiponectin levels. However, these findings showed that FEV₁/FVC & adipo/lept ratios are accounted as valuable indicators for evaluating the obesity syndrome and pulmonary efficiency in the asthma disease.
