ABSTRACT
Objective To discuss the risk factors for cardiac complications in infants of diabetic mothers (IDMs).Methods One hundred and seventy-one out of 228 IDMs hospitalized in Department of Pediatrics,Shenzhen Hospital of Peking University from Jan.2011 to Apr.2014,were involved,among them,there were 171 cases who had the complete mother's data during pregnancy,and they were received B ultrasonography whin 1 week after birth.All the infants were divided into 2 groups according to echocardiography within 1 week after birth:the observation group (the patients had cardiac complications) and the control group (the patients had normal heart).Conditions of IDMs and their mothers between the 2 groups were recorded and compared.Results In the 171 IDMs,there were 69 cases(38male and 31 female) in the observation group and 102 cases(59 males and 43 females) in the control group.There were 24 preterm infants,16 large for gestational age(LGA) infants in the observation group,while 47 preterm infants and 15 LGA in the control group,and which had no statistical difference between the both groups(x2 =0.129,2.163,1.995 ; all P ＞ 0.05).In the observation group,there were 7 (4.1％) newborns with hypoglycemia,24 (14.0％) women with advanced maternal age,24(14.0％) women with other gestational complications,19(11.1％) women having good control of their glucose serum levels,and 9(5.3％) women with impaired glucose tolerance.All the mentioned factors had statistical differences when compared with the control group[1 (0.6％) case,19 (11.1％) cases,15 (8.8％) cases,80(66.8％) cases,26(15.2％) cases] (x2 =7.752,5.707,9.423,43.735,3.917 ;all P ＜ 0.05,0.01).Logistic regression showed that women with other gestational complications as risk factors(OR =3.29,95％ CI 1.248-8.671),while having a good control of the glucose serum levels acted as a protectable factor(OR =0.098,95％ CI 0.045-0.217).Conclusions IDMs are prone to have cardiac complications if their mothers couldn't control the glucose serum levels during pregnancy,with other gestational complication and advanced maternal age and with more serious diabetes.
ABSTRACT
Objective To investigate the cardiac structure and hypertrophic cardiomyopathy of infant of diabetic mother(IDM),to analyze of the outcome of hypertrophic cardiomyopathy in IDM.Methods Totally 23 cases of IDM admitted in NICU from Feb.2012 to Jan.2013 were selected as observation group,randomly selected from the same period with gestational age of diabetic mother baby 23 cases as control group.The interventricular septum thickness,left ventricular posterior wall thickness,aortic valve internal diameter,right ventricular diameter,ejection fraction were detected and compared between the 2 groups.And echocardiography was followed up in 3 months and 6 months old.Results In IDM group,interventricular septum thickness [(3.20 ± 0.28) mm],left ventricular posterior wall thickness [(3.40 ± 0.31) mm] were significantly higher than those in control group (all P ＜ 0.05).Ejection fraction [(54.00 ± 3.76) × 10-2] was significantly lower than that in control group(P ＜ 0.05).Follow-up after 3 months,6 months old,interventricular septum thickness,left ventricular posterior wall thickness and ejection fraction returned to normal.Four of the 23 cases(17.4％) had cardiac malformations.Conclusions IDM has high morbidity of congenital heart disease,echocardiography should be done to identify hypertrophic cardiomyopathy and congenital heart disease after birth.IDM combined with hypertrophic cardiomyopathy is a transient,benign process,prognosis is good.
