Several studies have investigated the correlation between central obesity and inflammatory cytokines and the anti-inflammatory cytokine adiponectin. But, the correlation between central obesity and the anti-inflammatory cytokines IL-4, IL-5 has not been studied yet. Thus, we aimed to study the IL-4 and IL-5 correlation to central obesity in adolescent Egyptian girls among proinflammatory and anti-inflammatory cytokines. The study was carried out on 86 obese adolescent girls (BMI > 95 percentile) divided into two groups according to central obesity. The group I with waist to hip ratio <0.8 as a control and group II with waist to hip ratio >0.8 (central obesity). There was a significant increase in TNF-alpha (p < 0.0001), and IL-1 beta (p < 0.0001), as proinflammatory cytokines in group II, as compared to their corresponding group I. Group II showed a significant increase in the anti-inflammatory cytokines IL-4 and IL-5 than group I at (p < 0.0001) and (p < 0.0005) respectively. In addition there was a significant decrease in the anti-inflammatory adiponectin and an increase in the inflammatory leptin levels in group II at (p < 0.0001) and (p < 0.0001) respectively in comparison to group I. A high positive correlation has been observed between waist to hip ratio, leptin, TNF-alpha, IL-1-beta, IL-4 and IL-5 at (r = 0331, p < 0.03), (r = 0.559, p < 0.001), (r = 0.435, p < 0.004), (r = 0.509, p < 0.001), (r = 0.550, p < 0.0015), in group II respectively and a high negative one with adiponectin at (r = -0.410, p < 0.0001). We concluded that central obesity lowers adiponectin plasma level through increasing proinflammatory adipokines such as TNF-alpha, IL-1 beta, leptin. Further studies are needed to explore the positive correlation we found between central obesity and the anti-inflammatory cytokines IL-4 and IL-5 known to be associated with bronchial asthma.
