RESUMO
BACKGROUND AND AIMS: Advanced glycation end (AGE) products play a role in the progression of diabetic complications. Gluten-free diet (GFD) might affect AGE levels in patients who adhere to a GFD because of coeliac disease (CD). The aim of our study was to compare skin AGE levels and soluble receptor AGE levels (sRAGE) in patients with type 1 diabetes (T1DM) with (T1DM + CD) and without CD (T1DM - CD) and healthy controls. METHODS AND RESULTS: We recruited 25 T1DM + CD and 25 T1DM - CD patients, matched for age, gender, diabetes duration, and glycaemic control alongside 25 healthy controls. We collected demographic, clinical and biochemical characteristics, including skin autofluorescence (AF), sRAGE and hs-CRP levels. The duration of T1DM in patients was 30 ± 14 (+CD) and 29 ± 14 years (-CD), whereas CD duration in T1DM + CD patients was 14 ± 10 years. Skin AF levels in T1DM patients were higher compared to healthy controls (2.5 ± 0.6 versus 1.9 ± 0.4, p < 0.01) and skin AF was independently associated with age (r = 0.72, p < 0.01). sRAGE levels were higher in T1DM - CD patients compared to healthy controls (1554 ± 449 versus 1309 ± 400, p = 0.049) and independently associated with creatinine levels (r = 0.32, p < 0.01). CONCLUSION: Our study demonstrates that skin AGE and sRAGE levels are elevated in T1DM patients compared with healthy controls. No difference in skin AF or sRAGE levels between T1DM patients with or without CD were observed. The present study suggests that differences in microvascular complications between T1DM and T1DM + CD patients are not due to differences in skin AF or sRAGE levels.

A gluten-free diet (GFD) is recommended for all patients with coeliac disease (CD). The spectrum of gluten-related disorders in the early 1980s was simple: CD and dermatitis herpetiformis. In the last few years, wheat allergy, gluten ataxia and noncoeliac gluten sensitivity have become new gluten-related topics. Adherence to GFDs in CD is limited and factors influencing adherence are poorly understood. Noncoeliac gluten sensitivity has stimulated the GFD food industry not only in Australia but all over the world. This article provides an overview of GFD in daily practice.

AIMS: Type 1 diabetes mellitus and coeliac disease are two chronic illnesses associated with each other. Both diseases and their treatments can seriously impair quality of life. The objective of the present study was to investigate health-related quality of life in adult patients diagnosed with both Type 1 diabetes and coeliac disease and compare this with healthy control subjects and control subjects who have Type 1 diabetes only. METHODS: A generic measure of health-related quality of life (RAND-36) and a measure of diabetes-specific quality of life (DQOL) questionnaires were sent to patients diagnosed with both Type 1 diabetes and coeliac disease. The control group consisted of patients with Type 1 diabetes without coeliac disease matched for age, gender and socio-economic status. Generic quality of life scores were compared with data from healthy Dutch control subjects. RESULTS: Fifty-seven patients with Type 1 diabetes and coeliac disease were included and no associations between clinical characteristics and quality of life were observed. Women reported a lower quality of life in social functioning, vitality and mental health than men (all P < 0.05). A lower diabetes-specific quality of life was observed regarding diabetes-related worries and social worries in patients with Type 1 diabetes and coeliac disease compared with patients with Type 1 diabetes. Compared with healthy control subjects, quality of life in patients with Type 1 diabetes and coeliac disease was significantly lower, particularly social functioning (Cohen's d = 0.76) and general health perception (Cohen's d = 0.86). CONCLUSIONS: The additional diagnosis of coeliac disease and treatment by gluten-free diet in adult patients with Type 1 diabetes has a considerable, negative impact on quality of life and diabetes-specific quality of life. Women are particularly affected and social functioning and general health perception is compromised.
