  Objective: To determine the effect of coeliac disease and treatment with a gluten-free diet on growth and glycaemic control in asymptomatic children with Type 1 diabetes.
Methods: Data were compared in children with coeliac disease diagnosed by annual antibody screening and jejunal biopsy and treated with a gluten-free diet (n = 49) against individuals who were antibody negative (n = 49) matched for age, sex and duration of diabetes.
Results: No differences in growth were observed. In the years prior to diagnosis of coeliac disease, mean glycated haemoglobin (HbA1c) was lower in cases compared with control subjects [8.3 ± 1.1% vs. 8.7 ± 0.9%, P = 0.02 (mean ± sd)]. In cases, HbA1c deteriorated 12 months from the start of a gluten-free diet to levels similar to control subjects (8.9 ± 1.5% vs. 8.8 ± 1.5%, P-value for analysis of variance = 0.9). In regression analysis, the diagnosis of coeliac disease and start of a gluten-free diet was associated with a rise in HbA1c in the first year of treatment [odds ratio 1.56 (95% confidence intervals 1.16–2.10), P = 0.003] after adjusting for insulin dose and regimen and other variables.
Conclusions: In children with Type 1 diabetes, lower HbA1c prior to diagnosis of silent coeliac disease rises following treatment with a gluten-free diet to levels similar to those without coeliac disease. Although unproven, these observations may relate to abnormalities at the small bowel mucosa before the appearance of circulating coeliac antibodies.

Aims

We prospectively evaluated the effect of insulin intensification on glycaemic control and lipid levels in children and young persons with Type 1 diabetes in relation to ethnicity.

Methods

In the first 2 years of a 3-year observation period, as part of routine clinical care, 231 children and young persons (40% white, 28% South Asian, 32% black) from a single clinic were offered intensive insulin therapy. After 2 years, 222 were on intensive therapy and their data were compared between ethnic groups at the end of year 3.

Results

We observed ethnic differences in HbA1c levels during the study [study beginning and end: white children and young persons 77 and 70 mmol/mol (9.2 and 8.6%) vs. South Asian 72 and 68 mmol/mol (8.7 and 8.4%) vs. black 83 and 79 mmol/mol (9.7 and 9.4%), P-value for ANCOVA = 0.007]. By study end, South Asians had the lowest HDL cholesterol (2.0 vs. 1.4 vs. 1.6 mmol/l, P-value = 0.03) and highest triglyceride levels (0.9 vs. 1.8 vs. 1.0 mmol/l, P-value = 0.001). In linear mixed modelling, after adjustment for socio-economic deprivation and other covariates: (1) black ethnicity was associated with poorer glycaemic control (P < 0.001) and (2) South Asian ethnicity was associated with higher triglyceride levels (P < 0.001), independent of HbA1c.

Conclusions

The effect of insulin intensification on glycaemic control and lipid profile in children and young persons with Type 1 diabetes differs in relation to ethnic group.
