Abstract

OBJECTIVE: To evaluate the cord leptin levels of newborns in relation to birthweight and Gestational Diabetes (GD) either regulated by insulin or diet. STUDY DESIGN: A total of 62 patients were included in the study. Patients with impaired oral glucose tolerance test were included with diagnosis of GD (n=41). Control group consisted of women with normal plasma glucose level and 50-gr oral glucose challenge test (n=21). Twenty six of women with GD had blood glucose control by diet, while 15 required insulin. The blood samples were taken from the umblical cord of the newborns of GD and the control group for leptin levels. RESULTS: Birthweight of babies born to healthy mothers, mothers with GD regulated by diet and insulin were 3197.14±348.2 gr, 3496.11±734.9 gr and 3642.86±843.8 gr, respectively (p=0.05). Percentages of macrosomic babies were 4.8%, 11.5% and 33.3% in healthy women, women with GD regulated by diet and insulin, respectively (p<0.05). ). Cord blood leptin levels were higher in women with GD requiring insulin (6.1 ng/ml, range: 0.48-28.5) compared to women with GD regulated by diet (2.7 ng/ml, range: 0.5-54.7) and healthy mothers (2.0 ng/ml, range: 0.2-6.4, p<0.05). Cord blood leptin level was positively correlated with BMI (r:0.44, p<0.01), weight of mother (r:0.43, p<0.01), birthweight (r:0.37, p<0.05), and presence of GD and necessity of insulin (r:0.41, p<0.01).Cord blood leptin level was the only factor defining maternal GD requiring insulin in ROC analysis (AUC:0.77, p<0.01). Cord blood leptin level equal to or higher than 4.1 ng/ml had a sensitivity of 80% and specificity of 79% in defining GD with insulin requirement (positive likelihood ratio:3.68) CONCLUSION: In this study there is a minimal clinical effect of cord blood leptin on macrosomia in women with GD, although it is increased in GD and associated with birthweight. Therefore overgrowth may be a result of direct anabolic effect of insulin, rather than indirect effect via leptin.

Özet

AMAÇ: İnsülin ya da diyetle regüle edilen gestasyonel diabet te (GD) yenidoğan kordon leptin seviyelerinin doğum ağırlığına göre değerlendirilmesi. GEREÇ VE YÖNTEM: 62 hasta çalışmaya dahil edildi. Oral glukoz tolerans testi bozuk olan 41 GD hastası çalışmaya da hil edildi. Glukoz seviyesi ve 50 gram oral glukoz tolerans tes ti normal olan 21 vaka control grubunu oluşturdu. GD hastala rında kan glukoz seviyesi 26 vakada dietle, 15 vakada insülin le kontrol altına alındı. Leptin seviyesi için kan örnekleri yeni doğanların umblikal kordonlarından alındı. BULGULAR: Sağlıklı, diyetle kontrol edilen ve insülinle kontrol altına alınan vakaların yenidoğanlarının doğum kiloları sırasy la 3197,14±348,2 gr, 3496,11±734,9 gr ve 3642,86±843,8 gr, idi (p=0.05). Sağlıklı, diyetle kontrol edilen ve insülinle kontrol altına alınan vakaların yenidoğanlarında makrozomi oranları sı rasıyla 4,8%, 11,5% ve 33,3% olarak bulundu (p<0,05). İnsü li ne ihtiyaç duyan GD hastalarında (6,1 ng/ml, 0,48-28,5) di yetle regüle GD hastalarına (2,7 ng/ml, 0,5-54,7) ve sağlıklı an nelere (2,0 ng/ml, 0,2-6,4) göre kordon leptin seviyeleri daha yüksekti. (p<0,05). Kordon leptin seviyesi ile vücut kitle indek si (r:0,44, p<0,01), anne kilosu, (r:0,43, p<0,01), doğum ağırlı ğı (r:0,43, p<0,01), GD varlığı ve insulin ihtiyacı (r:0,41, p<0.01) arasında pozitif korelasyon saptandı. ROC analizinde kordon leptin seviyesi insulin bağımlı GD için tek tanımlayıcı faktördü (AUC:0,77, p<0,01). Kordon leptin seviyesinin 4.1 ng/ml’ye eşit ya da büyük olması 80% sensitivite ve 79% spe sifite ile insulin bağımlı GD tanımlıyordu. SONUÇ: Bu çalışmada kordon leptin seviyeleri GD’te yüksel diği ve doğum ağırlığı ile ilişkili olduğu halde GD hastalarında makrozomi üzerinde minimal klinik etkisi bulunmuştur. Bu ne denle makrozomi leptinin indirek etkisinden çok insülinin direk anabolic etkisinden kaynaklanabilir.
