A study of serum levels of leptin, ghrelin and tumour necrosis factor-alpha in child patients with cyanotic and acyanotic, congenital heart disease.
J Pak Med Assoc Jan ;63(11):1332-7.

Objective: To investigate the serum levels of leptin, ghrelin and tumour necrosis factor-alpha in children with cyanotic and acyanotic congenital heart disease. Methods: The prospective cohort study, was conducted at imam Ali Hospital, Zahedan University of Medical Sciences, Iran, in 2009-10 and comprised 64 subjects, including patients and controls. Using enzyme-linked immunosorpent assay kits, serum levels of ghrelin, leptin and tumour necrosis factor-alpha were measured and compared among patients (both cyanotic and acyanotic) and the controls, SPSS version 20 was used for statistical analysis. Results: Of the 64 subjects, 24 (37.5%) were cyanotic, 21(32.8%) were acynotic and 19(29.68%) were healthy controls. The three groups were homogenous in terms of age and gender characteristics. There was no significant difference among the groups leptin, ghrelin and tumour necrosis factor-alpha serum levels (p>0.05). There were also no significant differences in terms of weight, height and body mass index (P>0.05). Conclusion: Serum levels of ghrelin, leptin and tumour necrosis factor-alpha did not change in acyanotic and cyanotic patients with congenital heart disease, suggesting that other crucial factors may regulate individuals\' nutrient intake, growth, weight and energy intake and output.
