Inflammatory mediators increased significantly in obese children, and the glomerular filtration rate increased as the body mass index increased. To prevent obesity-related complications in adulthood, it is important to take measures to prevent development of obesity during childhood.
The aim of this study is to evaluate growth and insulin-like growth factor 1 (IGF-1) and insulin-like growth factor binding protein 3 (IGFBP-3) levels in infants with congenital heart disease (CHD) pre-and postoperatively over a period of a year. Anthropometric values and serum levels of IGF-1 and IGFBP-3 of 40 infants with CHD (20 cyanotic and 20 acyanotic) were compared with 32 healthy controls. Acyanotic infants and infants with pulmonary hypertension (PH) presented signifi cantly more growth failure. Preoperatively, serum IGF-1 and IGFBP-3 levels were lower in the acyanotic group than the cyanotic and the control groups (p = 0.22; p < 0.01). The upward trend in IGF-1 and IGFBP-3 levels in this year-long study demonstrated that the values in the third month and the fi rst year were higher than the preoperative values (p < 0.05). The parallel increase of weight gain and IGF-1, IGFBP-3 levels were the best evidence that these parameters are good nutritional indicators. Timing the corrective surgery before chronic malnutrition or PH develops is an important issue to maintain a normal growth for children with CHD.
Aim: To examine the relationship between inflammation criteria and body mass index in otherwise‐healthy obese schoolchildren and to evaluate the effect of obesity on renal functions. Methods: Sixty‐five otherwise‐healthy obese children (median age 10.8 y, range 7.1–16.5 y; median body mass index 26.8 kg/m2, range 19.9–38.7 kg/m2) and 20 healthy controls (median age 12.4 y, range 10.1–17.1 y; median body mass index 18.8 kg/m2, range 17.3–23.1 kg/m2) were included. Blood and urine samples were taken from every child. Results: Children in the obese and control groups had similar age and sex distributions (p>0.05). Inflammatory mediators were higher in obese children (p<0.05). A significant positive correlation was found between glomerular filtration rate and body mass index in the whole study group (r=0.39, p=0.001). A positive correlation was found between body mass index standard deviation and inflammatory mediators and glomerular filtration rate. No significant difference existed regarding protein and microalbumin excretion in the urine. Conclusion: Inflammatory mediators increased significantly in obese children, and the glomerular filtration rate increased as the body mass index increased. To prevent obesity‐related complications in adulthood, it is important to take measures to prevent development of obesity during childhood.
A 14-year-old female with Gaucher disease presented with hydrocephalus, corneal opacities, cirrhosis, and cardiac valvular involvement. A homozygous D409H mutation was identified. She underwent surgery for aortic and mitral valve replacement. Because of severe calcification of the aortic root, no successful valve replacement was performed. She died on the third day after the explorative cardiac surgery. Cardiac abnormalities represent a life-threatening presentation of the homozygous D409H mutation. Identification of this type is essential prior to initiating appropriate therapy with enzyme replacement and cardiac corrective surgery.
Impairment of right ventricular functions, especially due to chronic pulmonary regurgitation (PR), is a well-known entity in patients with tetralogy of Fallot (ToF) after repair. The aim of this study was to examine the relation between B-type natriuretic peptide (BNP) levels and right ventricular dysfunction by cardiopulmonary exercise test (ET) in patients after repair of ToF. Twenty-five patients with a mean age of 14.1 +/- 4.4 years at follow-up who underwent repair of ToF at a mean age of 4.9 +/- 5.1 years and 29 age- and sex-matched healthy children at a mean age of 13.1 +/- 2.8 years were enrolled in this study. Plasma BNP levels were measured at baseline and at maximal exercise. The volume of right ventricle (RV) and the degree of PR were assessed by two-dimensional echocardiography and color Doppler. Plasma BNP levels were significantly higher in patients with ToF than in controls (28.3 +/- 24.1 vs 7.4 +/- 2.3 pg/mL, p = 0.0001). Exercise was associated with increased plasma BNP levels in both groups. A greater increase in BNP was noted in patients with ToF than in controls (37.6 +/- 27.5 vs 11.3 +/- 4.5 pg/mL, p = 0.0001). Forced vital capacity (FVC%) (84.9 +/- 16.9 vs 98.4 +/- 18.2, p = 0.01) and forced expiratory volume during the 1st second (FEV1%) (91.5 +/- 19.3 vs 103.8 +/- 16.1, p = 0.02) were decreased, exercise duration (ED) (10.1 +/- 1.9 vs 11.4 +/- 1.7 min, p = 0.02), maximum heart rate (HRmax) (171.2 +/- 18.9 vs 186.4 +/- 13.9 /min, p = 0.004), and maximum oxygen uptake (VO(2)max) (1.56 +/- 0.53 vs 2.1 +/- 0.6 L/min, p = 0.007) were lower in patients with ToF. There were significant correlations between the degree of PR and ED (r =-0.3, p = 0.009), HRmax (r =-0.4, p = 0.001), and VO(2)max (r =-0.4, p = 0.001). The correlations were significant both before and after exercise, being more pronounced after exercise between BNP level and the degree of PR (r = 0.6, p = 0.0001). As a result, the severity of PR has a negative influence on right ventricular functions and there is significant relation between right ventricular functions and exercise capacity after repair of tetralogy of Fallot.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
