HbA1c levels in non-diabetic Dutch children aged 8,9 years: the PIAMA birth cohort study

H. Jansen
Abstract Aim, Glycated haemoglobin (HbA1c) is considered the best index of glycaemic control in established diabetes. It may also be useful in the diagnosis of diabetes and as a screening tool. Little is known about the distribution of HbA1c in healthy children and its predictors. The aim of this study is to describe the distribution of HbA1c in non-diabetic Dutch children aged 8,9 years and to investigate potential associations of HbA1c in this group. Methods HbA1c was measured in 788 non-diabetic children aged 8,9 years participating in the PIAMA birth cohort study. Data on parents and children were collected prospectively by questionnaires. Weight, height and waist and hip circumference of the children were measured when blood samples were taken. Results, Mean (sd) HbA1c was 4.9 0.33%, range 3.5,6.0%. HbA1c was significantly higher in boys (4.9 0.31 vs. 4.9 0.33%) and in children of mothers with gestational diabetes (5.0 0.37 vs. 4.9 0.32%). We found a significant inverse association between HbA1c and haemoglobin (regression coefficient: ,0.169 (95% CI ,0.221 to ,0.118), P < 0.001). HbA1c was not significantly associated with age, body mass index, waist circumference, parental diabetes or maternal body mass index. Conclusions, We found no significant relation between known risk factors for Type 2 diabetes and HbA1c at age 8,9 years. Moreover, there was a significant inverse association between haemoglobin and HbA1c. These results suggest that HbA1c may not only reflect the preceding blood glucose levels, but seems to be determined by other factors as well. [source]

Circulating adipocytokines in non-diabetic and Type 1 diabetic children: relationship to insulin therapy, glycaemic control and pubertal development

F. Celi
Abstract Aim To determine the influence of Type 1 diabetes mellitus on circulating adipocytokines in children. Methods The circulating concentrations of leptin, adiponectin, resistin and tumour necrosis factor (TNF)-, were measured in 91 children, aged 11.1 2.7 years, with Type 1 diabetes mellitus (T1DM). Ninety-one healthy children were selected as control subjects. Results Body mass index-adjusted leptin concentrations were higher in the pubertal diabetic children compared with the control children. There was a significant positive correlation between leptin and daily insulin dose in the diabetic group. Circulating adiponectin concentrations were higher in the prepubertal diabetic children and were positively associated with HbA1c. Resistin concentrations were lower in the prepubertal non-diabetic subjects compared with the pubertal non-diabetic children, whose values were higher than those of the diabetic children. TNF-, concentrations were similar in non-diabetic and diabetic children. Conclusions Circulating concentrations of adipocytokines are abnormal in Type 1 diabetic children, although the direction of change differs by cytokine. Pubertal development, in addition to insulin treatment and glycaemic control, also influences the concentrations. [source]

A phase 2 clinical trial of metformin as a treatment for non-diabetic paediatric non-alcoholic steatohepatitis

J. B. Schwimmer
Summary Background :,Children with non-alcoholic steatohepatitis are insulin-resistant and metformin has been proposed as a potential therapy. However, paediatric safety and efficacy data are absent. Aim :,To test the hypothesis that metformin therapy will safely improve markers of liver disease in paediatric non-alcoholic steatohepatitis. Methods :,Single-arm open-label pilot study of metformin 500 mg twice daily for 24 weeks in non-diabetic children with biopsy-proven non-alcoholic steatohepatitis. Results :,Ten obese children (mean body mass index 30.4) enrolled and completed the trial. Mean alanine aminotransferase and aspartate aminotransferase (AST) improved significantly (P < 0.01) from baseline (184, 114 U/L) to end of treatment (98, 68 U/L). Alanine aminotransferase normalized in 40% and AST normalized in 50% of subjects. Children demonstrated significant improvements in liver fat measured by magnetic resonance spectroscopy (30,23%, P < 0.01); insulin sensitivity measured by quantitative insulin sensitivity check index (0.294,0.310, P < 0.05); and quality of life measured by pediatric quality of life inventory 4.0 (69,81, P < 0.01). Conclusion :,Open-label treatment with metformin for 24 weeks was notable for improvement in liver chemistry, liver fat, insulin sensitivity and quality of life. A large randomized-controlled trial is needed to definitively determine the efficacy of metformin for paediatric non-alcoholic steatohepatitis. [source]

Post-transplant glucose status in 61 pediatric renal transplant recipients: Preliminary results of five Turkish pediatric nephrology centers. Pediatr Transplantation 2010:14:203,211 2009 John Wiley & Sons A/S. Abstract:, To assess the incidence, risk factors and outcomes of PTDM, a total of 61 non-diabetic children (24 girls, 37 boys, age: 14.5 2.1 yr) were examined after their first kidney transplantation (37.3 21.6 months) with an OGTT. At baseline, 16 (26.2%) patients had IGT, 45 (73.8%) had NGT, and no patient had PTDM. No significant difference was shown between TAC- and CSA-treated patients in terms of IGT. Higher BMI z -scores (p = 0.011), LDL-cholesterol (p < 0.05) and triglyceride levels (p < 0.01), HOMA-IR (p = 0.013) and lower HOMA-%, (p = 0.011) were significantly associated with IGT. Fifty-four patients were re-evaluated after six months; eight patients with baseline IGT (50%) improved to NGT, three (19%) developed PTDM requiring insulin therapy, five (31%) remained with IGT, and four patients progressed from NGT to either IGT (two) or PTDM (two). These 12 progressive patients had significantly higher total cholesterol (p < 0.05), triglycerides (p < 0.05), HOMA-IR (p < 0.01) and lower HOMA-%, (p < 0.0) than non-progressive patients at baseline. We can conclude that post-transplantation glucose abnormalities are common in Turkish pediatric kidney recipients, and higher BMI z -scores and triglyceride concentrations are the main risk factors. Considering that the progressive patients are significantly more insulin resistant at baseline, we suggest that the utility of both HOMA-IR and HOMA-%, in predicting future risk of PTDM and/or IGT should be evaluated in children.

Body fat related to daily physical activity and insulin concentrations in non-diabetic children

Magnus Dencker
Summary This study explored the associations between body fat versus daily physical activity and insulin concentrations in non-diabetic young children in a cross-sectional study of 172 children (93 boys and 79 girls) aged 8,11 years. Blood samples were analysed for serum insulin and daily physical activity was measured by accelerometers. Time spent performing vigorous activity was estimated from accelerometer data by using established cut-off points. Dual-energy x-ray absorptiometry (DXA) was used to quantify abdominal fat mass (AFM) and total body fat (TBF), also calculated as percentage of body weight (BF%). Body fat distribution was calculated as AFM/TBF. Body fat distribution was independently linked to both insulin concentrations and physical activity. In contrast, TBF, AFM, and BF% were linked to physical activity only and not to insulin concentrations. In conclusion in this population of non-diabetic children, body fat distribution was independently associated with increased concentrations of insulin and deceased amount of vigorous activity per day. Also, AFM, TBF, and BF% were independently related to minutes of vigorous activity per day. [source]
