Unraveling chronic kidney disease in children: a surprising manifestation of celiac disease. Front Pediatr 2024; 12:1384591. [PMID: 38720942 PMCID: PMC11076832 DOI: 10.3389/fped.2024.1384591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/09/2024] [Accepted: 04/05/2024] [Indexed: 05/12/2024] Open
Abstract
Celiac disease, firstly described in children, is a type of T-cell enteropathy that occurs in individuals genetically predisposed to gluten exposure. The estimated global prevalence of celiac disease is continuously increasing. Although, traditionally, celiac disease was diagnosed in children with failure to thrive and digestive issues, it is now recognized that may present with a wide range of symptoms beyond gastrointestinal ones. Celiac disease continues to pose significant challenges due to the continuous advancement of knowledge in understanding its pathophysiology, diagnosing the condition, managing its effects, and exploring potential therapeutic approaches. The prevalence of celiac disease is increased among individuals with chronic kidney disease, also. The most frequent associations are with diabetic nephropathy, IgA nephropathy and urolithiasis. A gut-kidney axis has been recognized to play a significant role in chronic kidney diseases. This literature review aims to review the chronic renal pathology associated with celiac disease, with emphasis on childhood.

Gluten-Free Diet in Co-Existent Celiac Disease and Type 1 Diabetes Mellitus: Is It Detrimental or Beneficial to Glycemic Control, Vascular Complications, and Quality of Life? Nutrients 2022; 15:nu15010199. [PMID: 36615856 PMCID: PMC9824312 DOI: 10.3390/nu15010199] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 12/28/2022] [Accepted: 12/29/2022] [Indexed: 01/03/2023] Open
Abstract
Celiac disease (CeD) is associated with type 1 diabetes mellitus (T1DM), and both have the same genetic background. Most patients with T1DM who develop CeD are either asymptomatic or have mild CeD-related gastrointestinal symptoms. Therefore, children affected by T1DM should undergo screening for asymptomatic CeD. The aim of this review is to highlight the influence of a gluten-free diet (GFD) on glycemic control, growth rate, microvascular complications, and quality of life in patients with T1DM and CeD. PubMed, Google Scholar, Web of Science, and Cochrane Central databases were searched. Reports reviewed were those published from 1969 to 2022 that focused on the interplay of T1DM and CeD and examined the effect of diet on glycemic control, growth rate, and quality of life. The most challenging aspect for a child with T1DM and CeD is that most GFD foods have a high glycemic index, while low glycemic index foods are recommended for T1DM. Interestingly, dietary therapy for CeD could improve the elevated HbA1c levels. Avoiding gluten added to a diabetic dietary regimen in T1DM patients might impose practical limitations and lead to important restrictions in the lifestyle of a young patient. Consequently, non-adherence to GFD in patients with T1DM and CeD is common. GFD in patients with T1DM and CeD seems to lower the incidence of micro- and macrovascular complications, but this requires further investigation. It seems that adherence to GFD in young patients with T1DM and CeD leads to regular growth and a stable body mass index without any negative effect on HbA1c or insulin requirements. Furthermore, the lipid profile and quality of life seem to have improved with the introduction of GFD.

Evaluation of the Relationship Between Carotid Intima Media Thickness and Dietary Compliance in Pediatric Celiac Patients: A Single-Center Pilot Study. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2022; 41:2475-2485. [PMID: 34962314 DOI: 10.1002/jum.15934] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/18/2021] [Revised: 12/14/2021] [Accepted: 12/15/2021] [Indexed: 06/14/2023]
Abstract
OBJECTIVES This study aimed to show the relationship between gluten-free diet (GFD) compliance in Celiac Disease (CD) and early atherosclerotic findings in pediatric patients and to test the effectiveness of carotid-intima-media-thickness (cIMT) to possibly predict long-term compliance to the GFD. METHODS Patients from 6 to 18 years of age with a diagnosis of CD confirmed by endoscopic duodenal biopsy who were followed at our hospital's pediatric gastroenterology outpatient clinic between November 2020 and May 2021 were evaluated in this single-center, prospective study. The study patients were divided into two groups according to GFD compliance. Serologic and biochemical tests were conducted routinely during the follow-up period. cIMT was measured using ultrasound for both groups. RESULTS A total of 80 patients (GFD-non-compliant: n = 35, GFD-compliant: n = 45) were evaluated. No significant differences were observed between the groups in terms of demographic data and pathology results. The mean cIMT value was 0.44 ± 0.028 mm for the GFD-compliant group and 0.54 ± 0.036 mm for the GFD-non-compliant group, with a statistically significant between-group difference (P < .001). The receiver operating characteristic curve analysis showed an area under the curve of 0.992 (95% confidence interval [CI]: 0.978-1, P < .001) for discrimination of the groups. In addition, a cutoff value of 0.486 mm for cIMT showed 96% (95% CI: 0.83-0.99) sensitivity and 94% (95% CI: 0.79-0.99) specificity for distinguishing GFD-compliant patients from non-GFD-compliant patients. CONCLUSION In this study, the relationship between long-term GFD compliance and cIMT was demonstrated in CD. Currently used by some authors for the assessment of preclinical atherosclerosis, cIMT can also be used as a long-term indicator of dietary compliance as well as cardiovascular risk.

Autoimmune thyroiditis and celiac disease do not worsen endothelial function in subjects with type 1 diabetes: an observational study. Diabetol Metab Syndr 2022; 14:103. [PMID: 35870966 PMCID: PMC9308025 DOI: 10.1186/s13098-022-00877-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2022] [Accepted: 07/14/2022] [Indexed: 11/15/2022] Open
Abstract
BACKGROUND Type 1 diabetes (T1D) is frequently associated with autoimmune thyroiditis (AT) and coeliac disease (CD). Whether the coexistence of multiple autoimmune diseases increases cardiovascular risk is uncertain. We evaluated the effects of AT and CD on arterial wall thickening and endothelial function in patients with T1D. METHODS This observational study analyzed data from T1D patients regularly followed by the Diabetes Care Centre. Clinical and biochemical characteristics and micro and macrovascular complications were collected from the electronic medical records. All subjects performed Echo-Doppler to evaluate Intima-Media Thickness (IMT) of the common carotid artery (CCA) and endothelial function by the flow-mediated dilation (FMD) technique. The statistical analyses were performed by SPSS for Macintosh. Comparison between means was performed using the t-test for unpaired data and the Mann-Whitney U test. The ANalysis Of VAriance and the Tukey posthoc test were applied to compare patients with and without other autoimmune diseases, and control subjects. The p-value for statistical significance was set at p < 0.05. RESULTS A total of 110 patients were enrolled. Among these, 69 had T1D and 41 T1D and AT and or CD, of whom 33 AT, 7 CD, and 1 both AT and CD. The mean age was 35 years, mean HbA1c was 7.6%, and mean diabetes duration 18 years. The IMT of the CCA was not significantly different between T1D patients with and without concomitant autoimmune diseases (with AT and CD: right CCA 603 ± 186 µ, left 635 ± 175 µ; without AT and CD: right CCA 611 ± 176 µ, left CCA 631 ± 200 µ). FMD was also comparable between T1D groups, with AT and CD 7.9 ± 4.2%; without AT and CD 8.8 ± 4.4%. CONCLUSION Patients with T1D and concomitant AT and or CD show no worse morphological or functional vascular damage, evaluated by CCA IMT and brachial artery flow-mediated dilation, than patients with T1D alone.

Review article: Systemic consequences of coeliac disease. Aliment Pharmacol Ther 2022; 56 Suppl 1:S64-S72. [PMID: 35815828 PMCID: PMC9543231 DOI: 10.1111/apt.16912] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/18/2022] [Revised: 02/08/2022] [Accepted: 03/18/2022] [Indexed: 12/09/2022]
Abstract
BACKGROUND The best-known symptoms of coeliac disease are related to the gastrointestinal tract, but the disease may also present with various systemic manifestations outside the intestine. Some of these consequences may remain permanent in undiagnosed individuals or if the diagnostic delay is prolonged. However, for many of the systemic manifestations, the scientific evidence remains scant and contradictory. AIMS AND METHODS We conducted a narrative review of the most thoroughly studied and clinically relevant systemic consequences of coeliac disease, especially those that could be prevented or alleviated by early diagnosis. The review is intended particularly for physicians encountering these patients in daily clinical practice. RESULTS The possible systemic consequences of coeliac disease extend to multiple organ systems, the best studied of which are related to skeletal, reproductive, cardiovascular and neurological systems. Furthermore, the disease is associated with an elevated risk of psychiatric comorbidities, non-Hodgkin lymphomas and intestinal adenocarcinoma. CONCLUSIONS The various systemic consequences of coeliac disease play a significant role in the overall health of patients. Early diagnosis and treatment with a gluten-free diet appear to be beneficial for most, but not all of these conditions. The possible negative metabolic and psychosocial effects of the diet should be acknowledged during follow-up.

Atherosclerotic Cardiovascular Disease Prevalence Among Patients With Celiac Disease in the United States: An Observational Study. Mayo Clin Proc 2021; 96:666-676. [PMID: 33673917 DOI: 10.1016/j.mayocp.2020.04.051] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 04/07/2020] [Accepted: 04/14/2020] [Indexed: 11/21/2022]
Abstract
OBJECTIVE To assess the prevalence of atherosclerotic cardiovascular disease (ASCVD) by age and sex in patients with celiac disease and to determine associations between ASCVD and celiac disease. PATIENTS AND METHODS This is a retrospective cohort study which included adults (>18 years old) who had hospitalizations recorded in the National Inpatient Sample database in the United States from January 1, 2005, to December 31, 2014. Patients with celiac disease were matched (1:5) by age, sex, race, and calendar year to patients without celiac disease. Prevalence of ASCVD was calculated in patients with celiac disease and controls, and compared by sex and age groups. Associations between celiac disease and ASCVD were determined after adjustment for common cardiovascular risk factors. RESULTS Among 371,776,860 patients hospitalized in the United States between 2005 and 2014, 227,172 adults with celiac disease were matched to 1,133,701 controls. Young women with celiac disease (age <40 years) had a higher prevalence of ASCVD and higher adjusted odds (aOR) of ASCVD when compared with controls (aged 18 to 29 years aOR, 2.22 [95% CI 1.41 to 3.5]; P<.001; and aged 30 to 39 years aOR 1.54 [95% CI 1.19 to 1.99]; P<.001). Adults with celiac disease of all ages and sexes had increased adjusted odds of death if they had ASCVD (aOR aged <40 years 7.31 [95% CI 2.49 to 21.46]; P<.001; and aOR aged ≥40 years 2.02 [95% CI 1.68 to 2.42]; P<.001). CONCLUSION We found significantly higher prevalence and adjusted odds of ASCVD in young women with celiac disease when compared with matched controls. ASCVD was associated with significant mortality among patients with celiac disease.

Abstract
Coeliac disease (CD) is a chronic autoimmune disease that is characterized by malabsorption in sensitive individuals. CD is triggered by the ingestion of grains containing gluten. CD is concomitant with several other disorders, including dermatitis herpetiformis, selective IgA deficiency, thyroid disorders, diabetes mellitus, various connective tissue disorders, inflammatory bowel disease, and rheumatoid arthritis. The advent of high throughput technologies has provided a massive wealth of data which are processed in various omics scale fields. These approaches have revolutionized the medical research and monitoring of the biological systems. In this regard, omics scaled analyses of CD by Comparative Toxicogenomics Database (CTD), DISEASES, and GeneCards databases have retrieved 2656 CD associated genes. Amongst, 54 genes were assigned by Venn Diagram of the intersection to be shared by these 3 databases for CD. These common genes were subjected to further analysis and screening. The Enrich database, GeneMANIA, Cytoscape, and WebGestalt (WEB-based GEne SeT AnaLysis Toolkit) were employed for functional analysis. These analyses indicated that the obtained genes are mainly involved in the immune system and signalling pathways related to autoimmune diseases. The STAT1, ALB, IL10, IL2, IL4, IL17A, TGFB1, IL1B, IL6, TNF, IFNG hub genes were particularly indicated to have significant roles in CD. Functional analyses of these hub genes by GeneMANIA indicated that they are involved in immune systems regulation. Moreover, 25 out of 54 genes were identified to be seed genes by the WebGestalt database. Gene set analysis with GEO2R tool from Gene Expression Omnibus (GEO) showed that there were 15 significant genes in GSE76168, 29 significant genes in GSE87460, 12 significant genes in GSE87458, 9 significant genes in GSE87457, 3753 significant genes in GSE112102 and 1043 significant genes in GSE102991 with differential expression in coeliac patients compared to controls. The IRF1and STAT1 genes were common between the significant genes from GEO and the 54 CD related genes from three public databases. In the light these results, nine key genes, including IRF1, STAT1, IL17A, TGFB1, ALB, IL10, IL2, IL4, and IL1B, were identified to be associated with CD. These findings could be used to find novel diagnostic biomarkers, understand the pathology of disease, and devise more efficient treatments.

Lipid profile, atherogenic indices, and their relationship with epicardial fat thickness and carotid intima-media thickness in celiac disease. North Clin Istanb 2019; 6:242-247. [PMID: 31650110 PMCID: PMC6790920 DOI: 10.14744/nci.2019.54936] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2018] [Accepted: 01/09/2019] [Indexed: 12/15/2022] Open
Abstract
OBJECTIVE: In this study, we aimed to investigate the presence of subclinical atherosclerosis by measuring epicardial fat thickness (EFT) and carotid intima–media thickness (cIMT), evaluate low-level inflammation with high-sensitivity C-reactive protein (hsCRP), and evaluate whether there is a relationship among lipid profile, atherogenic indices, and hsCRP with these subclinical atherosclerosis markers in patients with celiac disease (CD). METHODS: After exclusion and inclusion criteria were applied, 31 patients with CD (24 female, mean age: 39.4±12.3 years) and 32 healthy controls (21 female, mean age: 39.5±4.4 years), totally 63 cases, were recruited. Subclinical atherosclerosis was evaluated with EFT by transthoracic echocardiography and cIMT by ultrasonography. Inflammatory markers including erythrocyte sedimentation rate (ESR), hsCRP, and lipid profile were recorded. Also, atherogenic indices were calculated: Castelli risk index I and II (TG/HDL-c and LDL-c/HDL-c, respectively), atherogenic index of plasma (AIP; logarithm TG/HDL-c), non-HDL-c (TG-HDL-c), and atherogenic coefficient (AC; non-HDL-c/HDL-c). RESULTS: EFT was significantly higher in the CD group (0.49±0.10 vs. 0.49±0.09; p-value: 0.02). Although cIMT was higher in the patient group, it did not reach statistical significance (0.51±0.08, 0.47±0.08; p-value: 0.10). HDL cholesterol level was found to be significantly lower (42.0±8.8 vs. 50.0±13.7; p-value: 0.01), and the plasma atherogenic index was found to be significantly higher in the patient group (0.98±0.50 vs. 0.62±0.64; p-value: 0.02). hsCRP (3.51±3.18 vs. 1.92±1.40; p-value: 0.02) and ESR (17.2±12.8 with 9.7±3.1; p-value: 0.01) were found to be significantly higher in the CD group. Although there was a significant positive correlation between EFT and hsCRP (r: 0.453; p-value: 0.01), there was a significant negative correlation between cIMT and HDL-cholesterol (−0.339; p-value: 0.05), and a significant positive correlation with the other components of the atherogenic index was found. CONCLUSION: The risk of atherosclerosis has been increased in patients with CD. Chronic inflammation may be responsible for this increase along with atherogenic indices.

Abstract
AIMS To investigate whether in type 1 diabetes (T1DM) patients the concomitance of long-lasting celiac disease (CD) treated with a gluten free diet (GFD) impacts glycaemic control and the prevalence/severity of microvascular complications. METHODS A case-control, observational study was performed in 34 patients with T1DM and GFD-treated CD and 66 patients with T1DM alone matched for age, gender, and T1DM duration. Anthropometric parameters, glucose control (HbA1c), status of chronic complications and concomitant autoimmune diseases were evaluated. RESULTS HbA1c level was similar in T1DM + CD and T1DM alone (7.8 ± 1.0 vs 7.7 ± 1.1%, P = 0.57); insulin requirement was significantly higher in T1DM + CD compared with T1DM (P = 0.04). There were no differences in systolic blood pressure while diastolic blood pressure was significantly lower in T1DM + CD (P = 0.003). The prevalence/severity of microvascular complications was similar between the two groups. Glomerular filtration rate (eGFR) was significantly lower in T1DM + CD (100 ± 20 vs 110 ± 16 ml/min/1.73 m2, P = 0.007). CONCLUSIONS In patients with T1DM, the co-occurrence of long-term GFD-treated CD neither worsens glycemic control nor negatively impacts chronic microvascular complications. However, patients with T1DM + CD have lower eGFR values than those with T1DM alone.

Abstract
AIMS Low HDL cholesterol (HDL-C) levels have been described in patients with coexisting type 1 diabetes mellitus (T1DM) and celiac disease (CD). Data on other possible lipid abnormalities that could further increase cardiovascular risk in these patients are scarce and incomplete. Aim of this retrospective multicenter study was to evaluate whole lipid profiles, besides HDL-C, in children with T1DM associated with biopsy-proven CD, and to investigate the influence of age and degree of adherence to gluten-free diet (GFD) on lipid changes. METHODS A total of 261 children with both T1DM and CD were enrolled. Serum lipid profiles at CD diagnosis were compared with those after 1 year of GFD and with those of 224 matched children with T1DM alone. The adherence to GFD was judged by means of CD-related antibodies. RESULTS At CD diagnosis, children with T1DM + CD showed higher LDL cholesterol (LDL-C) compared to children with T1DM alone. Gluten withdrawal failed to normalize LDL-C levels, not even in completely adherent individuals. HbA1c values were not influenced by GFD. The youngest children were characterized at diagnosis by lower levels of total cholesterol and on treatment by a greater decrease in triglycerides levels. CONCLUSIONS An unfavorable lipid profile, characterized not only by low HDL-C levels but also by high LDL-C values, may increase the risk of cardiovascular disease in children with T1DM and untreated CD. Therefore, a strict gluten-free diet is mandatory in these children, especially the youngest.

Abstract
Celiac disease (CD) is an autoimmune response to ingestion of gluten protein, which is found in wheat, rye, and barley grains, and results in both small intestinal manifestations, including villous atrophy, as well as systemic manifestations. The main treatment for the disease is a gluten-free diet (GFD), which typically results in the restoration of the small intestinal villi, and restoration of other affected organ systems, to their normal functioning. In an increasing number of recently published studies, there has been great interest in the occurrence of alterations in the cardiovascular system in untreated CD. Herein, published studies in which CD and cardiovascular terms appear in the title of the study were reviewed. The publications were categorized into one of several types: (1) articles (including cohort and case-control studies); (2) reviews and meta-analyses; (3) case studies (one to three patient reports); (4) letters; (5) editorials; and (6) abstracts (used when no full-length work had been published). The studies were subdivided as either heart or vascular studies, and were further characterized by the particular condition that was evident in conjunction with CD. Publication information was determined using the Google Scholar search tool. For each publication, its type and year of publication were tabulated. Salient information from each article was then compiled. It was determined that there has been a sharp increase in the number of CD - cardiovascular studies since 2000. Most of the publications are either of the type "article" or "case study". The largest number of documents published concerned CD in conjunction with cardiomyopathy (33 studies), and there have also been substantial numbers of studies published on CD and thrombosis (27), cardiovascular risk (17), atherosclerosis (13), stroke (12), arterial function (11), and ischemic heart disease (11). Based on the published research, it can be concluded that many types of cardiovascular issues can occur in untreated CD patients, but that most tend to resolve on a GFD, often in conjunction with the healing of small intestinal villous atrophy. However, in some cases the alterations are irreversible, underscoring the need for CD screening and treatment when cardiovascular issues arise of unknown etiology.

Markers of inflammation and cardiovascular disease in recently diagnosed celiac disease patients. World J Cardiol 2017; 9:448-456. [PMID: 28603593 PMCID: PMC5442414 DOI: 10.4330/wjc.v9.i5.448] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/24/2016] [Revised: 03/03/2017] [Accepted: 04/10/2017] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate novel risk factors and biomarkers of cardiovascular disease in celiac disease (CD) patients compared with healthy controls.
METHODS Twenty adult patients with recent diagnosis of CD and 20 sex, age and body mass index-matched healthy controls were recruited during a period of 12 mo. Indicators of carbohydrate metabolism, hematological parameters and high sensitive C reactive protein were determined. Moreover, lipoprotein metabolism was also explored through evaluation of the lipid profile and the activity of cholesteryl ester transfer protein and lipoprotein associated phospholipase A2, which is also considered a specific marker of vascular inflammation. The protocol was approved by the Ethic Committee from School of Pharmacy and Biochemistry, University of Buenos Aires and from Buenos Aires Italian Hospital, Buenos Aires, Argentina.
RESULTS Regarding the indicators of insulin resistance, CD patients showed higher plasma insulin levels [7.2 (5.0-11.3) mU/L vs 4.6 (2.6-6.7) mU/L, P < 0.05], increased Homeostasis Model Assessment-Insulin Resistance [1.45 (1.04-2.24) vs 1.00 (0.51-1.45), P < 0.05] and lower Quantitative Sensitive Check index [0.33 (0.28-0.40) vs 0.42 (0.34-0.65), P < 0.05] indexes. Folic acid concentration [5.4 (4.4-7.9) ng/mL vs 12.2 (8.0-14.2) ng/mL, P < 0.01] resulted to be lower and High-sensitivity C reactive protein levels higher (4.21 ± 6.47 mg/L vs 0.98 ± 1.13 mg/L, P < 0.01) in the patient group. With respect to the lipoprotein profile, CD patients showed lower high density lipoprotein-cholesterol (HDL-C) (45 ± 15 mg/dL vs 57 ± 17 mg/dL, P < 0.05) and apo A-I (130 ± 31 mg/dL vs 155 ± 29 mg/dL, P < 0.05) levels, as well as higher total cholesterol/HDL-C [4.19 (3.11-5.00) vs 3.52 (2.84-4.08), P < 0.05] and apo B/apo A-I (0.75 ± 0.25 vs 0.55 ± 0.16, P < 0.05) ratios in comparison with control subjects. No statistically significant differences were detected in lipoprotein-associated lipid transfer protein and enzymes.
CONCLUSION The presence and interaction of the detected alterations in patients with CD, would constitute a risk factor for the development of atherosclerotic cardiovascular disease.

Abstract
Prevalence studies from around the world have established a substantial increase in the prevalence of celiac disease (CD) in patients with type 1 diabetes mellitus (T1DM). Approximately two-thirds of patients with T1DM and CD are asymptomatic for CD at diagnosis. We aim to provide an up-to-date state-of-the-art summary of the recommendations for serologic testing for CD in patients with T1DM and to clarify the debate on the need for screening and interventions. We searched Medline and Cochrane databases for studies of celiac autoimmunity and biopsy-proven CD in people with T1DM between January 1, 2000 and December 1, 2015. CD was found to be an independent risk factor for micro- and macrovascular complications, as well as for increased morbidity in patients with T1DM. Publications, however, reveal controversy regarding the benefits of a gluten-free diet (GFD) on glycemic control, bone health, and quality of life in individuals with T1DM and asymptomatic CD. A multicenter, prospective randomized controlled trial aimed to investigate this issue is currently ongoing. Until resolution of the pros and cons of screening for CD, and of the benefit versus burden of GFD treatment in T1DM patients with asymptomatic CD, we recommend repeated screening for CD during childhood and adulthood, and treatment with GFD for those with biopsy-proven CD, even if asymptomatic.

Impact of type 1 diabetes mellitus and celiac disease on nutrition and quality of life. Nutr Diabetes 2017; 7:e239. [PMID: 28067892 PMCID: PMC5301040 DOI: 10.1038/nutd.2016.43] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/28/2016] [Revised: 08/26/2016] [Accepted: 09/14/2016] [Indexed: 11/30/2022] Open
Abstract
Objective: Type 1 diabetes mellitus (T1DM) and celiac disease (CD) are autoimmune diseases and have similar genetic patterns. T1DM treatment is based on diet, physical activity and insulin therapy, whereas CD depends on dietary changes with restriction of wheat, rye and barley. The aim of the study was to evaluate the quality of life (QoL) of individuals with the association of T1DM and CD, to characterize their nutritional status and to compare it with those with only one disease and healthier controls. Subjects/Methods: Sixty patients controlled by sex, age and body mass index (BMI) were stratified by previous diagnosis in: T1DM and CD (DMCD group); T1DM (DM group); CD (CD group); or healthy participants (HC). The SF-36 questionnaire was applied to assess psychological well being and results were compared with glycemic control and presence of complications related to diabetes, adhesion to gluten-free diet (GFD). Nutritional status and body mass composition were determined by BMI, waist circumference, bioimpedance, general laboratory tests and whole-body densitometry. Results: The time of diagnosis of T1DM was similar between DMCD and DM groups; however, the duration of CD was significantly higher in the CD group compared with DMCD. The SF-36 analysis revealed statistically significant differences between DM and HC groups in two domains: general health (P=0.042) and energy/vitality (P=0.012). QoL was also correlated with compliance to a GFD, and scores were similar in both groups: DMCD and CD. Forty percent of individuals in the CD group had visceral fat area above 100 cm2, as opposed to 20% in the other groups. Conclusions: Individuals of DMCD group had similar scores to DM, CD and HC on QoL, as well as on their nutritional status and bone metabolism. Thereby, we should conclude that the association of T1DM and CD did not deteriorate their health status.

Quality of Life in Type 1 Diabetes and Celiac Disease: Role of the Gluten-Free Diet. J Pediatr 2016; 179:131-138.e1. [PMID: 27720243 DOI: 10.1016/j.jpeds.2016.08.105] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/26/2016] [Revised: 08/10/2016] [Accepted: 08/31/2016] [Indexed: 12/14/2022]
Abstract
OBJECTIVE To evaluate quality of life (QoL) and glycemic control in youth with type 1 diabetes (T1D) and celiac disease vs T1D only. We hypothesized that QoL scores would be lower in youth with T1D and celiac disease and those nonadherent to the gluten-free diet (GFD). STUDY DESIGN This case control study included 35 youth with T1D and 35 with T1D and celiac disease matched for age, sex, diabetes duration, and hemoglobin A1c level. QoL was assessed in participants and parents using the Pediatric Quality of Life Inventory Generic Core Scale, Pediatric Quality of Life Inventory Diabetes Module. and the General Well-Being Scale; youth with T1D and celiac disease also completed the celiac disease-specific DUX questionnaire and parents completed the Pediatric Quality of Life Inventory Family Impact Scale. Questionnaires were scored from 0 to 100; higher scores indicate better QoL or well-being. Scores were compared between T1D vs T1D with celiac disease, with subgroup analysis by GFD adherence vs nonadherence and therapy (continuous subcutaneous insulin infusion vs multiple daily injections). RESULTS Youth with T1D and celiac disease reported similar generic and diabetes-specific QoL to T1D only. GFD nonadherent vs adherent youth reported lower diabetes-specific QoL (mean score 58 vs 75, P = .003) and lower general well-being (57 vs 76, P = .02), as did their parents (50 vs 72, P = .006), and hemoglobin A1c was higher (9.6% vs 8.0%, P = .02). Youth with T1D and celiac disease using continuous subcutaneous insulin infusion vs multiple daily injections had similar generic and diabetes-specific QoL and A1C (8.6 vs 8.2%, P = .44), but were less happy having to follow a lifelong diet (59 vs 29, P = .007). CONCLUSIONS Youth with T1D and celiac disease who do not adhere to the GFD have lower QoL and worse glycemic control. Novel strategies are required to understand and improve adherence in those with both conditions.

Abstract
BACKGROUND Patients with celiac disease (CD) may be at an increased risk of cardiovascular disease (CVD), yet CVD risk factors are not well defined in CD. The validated Framingham Heart Study 10-year general CVD risk score (FRS) that incorporates traditional CVD risk factors including body mass index (BMI) has not been previously studied in CD patients. AIMS To compare BMI and FRS in CD patients with population-based controls. METHODS Biopsy-proven CD patients were ascertained retrospectively and data on BMI, systolic blood pressure, hypertension, smoking status, and diabetes were obtained at initial and follow-up visits. FRS was calculated and compared with 4 matched general population non-CD controls from the 2009 to 2010 National Health and Nutrition Examination Survey (NHANES). RESULTS Of 258 total CD patients, 38.3% were overweight or obese compared with 69.8% of controls (P<0.001). In total, 174 CD patients met the inclusion criteria for FRS calculation. Of these, the median FRS was lower in CD patients compared with controls (3.9 vs. 4.2; P=0.011). In CD patients, tobacco use was significantly lower (P<0.001), whereas systolic blood pressure was significantly higher (P<0.01) than controls. CONCLUSIONS Global CVD risk is lower among patients with CD compared with population controls. Lower BMI and tobacco use among CD patients could account for this difference. These results suggest that factors other than those measured by FRS could contribute to the increased risk of CVD in CD observed in some studies.

Abstract
Background Association between celiac disease and type 1 diabetes in adults is still somewhat unclear, and that between celiac disease and type 2 diabetes even less known. We studied these issues in a large cohort of adult celiac disease patients. Methods The prevalence of type 1 and type 2 diabetes in 1358 celiac patients was compared with the population-based values. Furthermore, patients with celiac disease and concomitant type 1 or type 2 diabetes and those with celiac disease only underwent comparisons of clinical and histological features and adherence to gluten-free diet. Results The prevalence of type 1 diabetes (men/women) was 8.0 % /1.8 % in celiac patients and 0.7 % /0.3 % in the population, and that of type 2 diabetes 4.3 % /2.5 % and 4.4 % /3.0 %, respectively. Celiac patients with concomitant type 1 diabetes were younger (45 years vs 65 years and 52 years, P < 0.001) and more often screen-detected (43 % vs 13 % and 14 %, P < 0.001), had less other gastrointestinal diseases (8 % vs 40 % and 25 %, P = 0.028), more thyroidal diseases (18 % vs 16 % and 13 %, P = 0.043) and lower dietary adherence (71 % vs 95 % and 96 %, P < 0.001) compared with celiac patients with concomitant type 2 diabetes and patients with celiac disease only. Patients with concomitant type 2 diabetes had more hypercholesterolemia than the other groups (8 % vs 6 % and 4 %, P = 0.024), and both diabetes groups more hypertension (47 % and 31 % vs 15 %, P < 0.001) and coronary artery disease (29 % and 18 % vs 3 %, P < 0.001) than the patients with celiac disease only. Conclusions Type 1 diabetes was markedly overrepresented in celiac disease, especially in men, whereas the prevalence of type 2 diabetes was comparable with the population. Concomitant type 1 or type 2 diabetes predisposes celiac patients to severe co-morbidities and type 1 diabetes also to poor dietary adherence.

Cut to the chase: a review of CD26/dipeptidyl peptidase-4's (DPP4) entanglement in the immune system. Clin Exp Immunol 2016; 185:1-21.

Abstract
CD26/DPP4 (dipeptidyl peptidase 4/DP4/DPPIV) is a surface T cell activation antigen and has been shown to have DPP4 enzymatic activity, cleaving-off amino-terminal dipeptides with either L-proline or L-alanine at the penultimate position. It plays a major role in glucose metabolism by N-terminal truncation and inactivation of the incretins glucagon-like peptide-1 (GLP) and gastric inhibitory protein (GIP). In 2006, DPP4 inhibitors have been introduced to clinics and have been demonstrated to efficiently enhance the endogenous insulin secretion via prolongation of the half-life of GLP-1 and GIP in patients. However, a large number of studies demonstrate clearly that CD26/DPP4 also plays an integral role in the immune system, particularly in T cell activation. Therefore, inhibition of DPP4 might represent a double-edged sword. Apart from the metabolic benefit, the associated immunological effects of long term DPP4 inhibition on regulatory processes such as T cell homeostasis, maturation and activation are not understood fully at this stage. The current data point to an important role for CD26/DPP4 in maintaining lymphocyte composition and function, T cell activation and co-stimulation, memory T cell generation and thymic emigration patterns during immune-senescence. In rodents, critical immune changes occur at baseline levels as well as after in-vitro and in-vivo challenge. In patients receiving DPP4 inhibitors, evidence of immunological side effects also became apparent. The scope of this review is to recapitulate the role of CD26/DPP4 in the immune system regarding its pharmacological inhibition and T cell-dependent immune regulation.

Abstract
This review aims at summarizing the present knowledge on the clinical consequences of concomitant coeliac disease (CD) in adult patients with type 1 diabetes mellitus (T1DM). The cause of the increased prevalence of CD in T1DM patients is a combination of genetic and environmental factors. Current screening guidelines for CD in adult T1DM patients are not uniform. Based on the current evidence of effects of CD on bone mineral density, diabetic complications, quality of life, morbidity and mortality in patients with T1DM, we advise periodic screening for CD in adult T1DM patients to prevent delay in CD diagnosis and subsequent CD and/or T1DM related complications.

Abstract
BACKGROUND Coeliac disease has been associated with an increased risk of cardiovascular disease in some studies, whereas other studies have shown no association. We performed a systematic review and meta-analysis of cardiovascular disease in celiac disease. METHODS Pubmed, Cinahl, EMBASE and Medline via Ovid were searched for relevant articles published until January 5, 2015. English-language articles on studies with more than 20 patients were included, and were quality rated using the GRADE risk of bias tool. We used random-effects models and assessed heterogeneity using the I(2) statistic. RESULTS Ten studies were relevant, reporting the risk of myocardial infarction, cardiovascular death and stroke in 33,128/32,903/32,466 coeliac disease patients respectively. Only one study examined celiac disease and a composite measure of cardiovascular disease and this study found a hazard ratio of 1.10 (95%CI 1.03-1.28). In a meta-analysis, we observed an increased risk of stroke (OR 1.11; 95%CI 1.02-1.20). The risks of myocardial infarction (OR 1.12; 95%CI 0.83-1.40) and cardiovascular death (OR 1.12; 95%CI 0.96-1.29) were similar but were estimated with less certainty. Heterogeneity was low for all outcomes except for myocardial infarction where it was moderate. CONCLUSION Coeliac disease was associated with a modestly increased risk of cardiovascular disease, but the evidence base is limited.

Abstract
The association between celiac disease (CD), an autoimmune condition involving intestinal inflammation related to gluten ingestion, and type 1 diabetes has long been recognized. CD prevalence rates 4 to 6 times greater in adults with type 1 diabetes than in the general population. Much of the existing literature focuses on important implications related to the impact of a gluten-free diet on short-term outcomes in metabolic control and quality of life. Canadian Diabetes Association guidelines recommend targeted CD screening in patients with type 1 diabetes who have classic symptoms, such as abdominal pain, bloating, diarrhea, unexplained weight loss or labile metabolic control; however, a significant proportion (40% to 60%) of patients may have mild or absent symptoms. Recent evidence suggests that adult patients with both conditions are at higher risk for diabetes microvascular comorbidities, increased mortality and impaired bone health if the CD is untreated. The purpose of this review is to describe the association between CD and type 1 diabetes and to summarize recent literature that evaluates risks in patients with both conditions.

Abstract
AIM To derive a more precise estimation of carotid intima-media thickness (CIMT) levels in patients with type 1 diabetes mellitus (T1DM) by meta-analysis. METHODS PubMed and Embase databases were searched to identify all available studies comparing CIMT levels between T1DM group and control group. Meta-analysis was performed to compare the difference of overall mean CIMT levels between the two groups. Publication bias was evaluated by funnel plot, Begg' test and Egger' test. Meta-regression analysis was conducted to investigate the influential factors on CIMT difference. The meta-analysis was conducted by STATA 12.0 software. RESULTS A total of 1840 articles were obtained after searching databases; 47 studies were finally included in the meta-analysis. Significant heterogeneity was observed among these studies (Q = 768.75, P < 0.001, I(2) = 94.0%). Compared with the control group, the T1DM group had significantly higher CIMT levels (standardized mean difference: 1.01, 95% CI: 0.75-1.28; P < 0.001). A likely source of heterogeneity was Newcastle-Ottawa Scale (NOS) scores and sample size ratio of patents and controls. The funnel plot did not show a skewed or asymmetrical shape, and the result of Begg' test and Egger' test was P = 0.178 and P = 0.145 respectively. Accordingly, it could be assumed that publication bias was not present. CONCLUSION T1DM patients have significantly increased CIMT levels compared to control subjects.

Abstract
OBJECTIVE To investigate whether celiac disease (CD) associated with type 1 diabetes increases the risk of microvascular complications. RESEARCH DESIGN AND METHODS Patients (n = 56,514) aged >10 years with diabetes duration <20 years from 392 centers in Germany and Austria were assigned to one of three categories (n): no CD (50,933), biopsy-confirmed CD (812), or suspected CD (4,769; clinical diagnosis or positive antibodies). The confirmed and suspected groups were combined and analyzed for retinopathy or nephropathy. Cox proportional hazards regression was used to adjust for potential confounders (glycated hemoglobin [HbA1c], age at diabetes onset, sex, smoking, dyslipidemia, and hypertension). RESULTS Kaplan-Meier analysis revealed that retinopathy and nephropathy occurred earlier in the presence versus absence of CD: retinopathy at age 26.7 years (95% CI 23.7-30.2) in 25% of patients with CD vs. age 33.7 years (33.2-34.4) in 25% without CD and microalbuminuria at age 32.8 years (29.7-42.5) vs. 42.4 years (41.4-43.3). The adjusted risk for both retinopathy (hazard ratio 1.263 [95% CI 1.078-1.481]) and nephropathy (1.359 [1.228-1.504]) was higher in patients with diabetes and CD versus those without CD. Cox regression revealed CD as an independent risk factor for microvascular complications after adjustment for confounders. CONCLUSIONS CD is an independent risk factor for retinopathy and nephropathy in patients with type 1 diabetes. Our study therefore supports the recommendation for regular serologic testing for CD, even in the absence of clinical CD. Further prospective studies are required to investigate whether a gluten-free diet might reduce the risk of microvascular disorders in patients with diabetes and CD.

Abstract
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.

Abstract
Coeliac disease (CD) patients may exhibit a pro-inflammatory profile and fatty acids (FA) can influence inflammation through a variety of cellular pathways in them. The aims of the present study were to (1) evaluate the FA composition of erythrocytes obtained from newly diagnosed CD patients by lipidomic analysis and compare it with that in healthy subjects and (2) determine the effects of 1-year gluten-free diet (GFD) intervention. A total of twenty CD patients (five men and fifteen women; mean age 34.0 (sem 1.7) years) were evaluated at diagnosis and after 1 year of GFD intervention. A total of twenty healthy subjects (seven men and thirteen women; mean age 40.2 (sem 2.5) years) served as controls. CD patients on an unrestricted diet exhibited a significant 2.08-fold higher concentration of arachidic acid when compared with healthy subjects, suggesting that it can be considered as a putative marker of CD. Besides, the arachidonic acid (AA):dihomo-γ-linolenic acid ratio was 2.01-fold significantly lower in CD patients than in healthy subjects (P< 0.01), underlying an inefficient synthesis of PUFA from their precursors in terms of desaturase activity. In addition, mainly due to lower concentrations of docosahexaenoic acid, the inflammation marker AA:docosahexaenoic acid ratio was 1.40-fold significantly higher in CD patients than in healthy subjects. After 1 year of GFD intervention, FA concentrations in CD patients were still different from those observed in healthy subjects. The lipidomic analysis of erythrocyte membranes confirmed the presence of an altered FA composition in CD patients and the GFD's ability to modify FA profile, even if 1-year GFD intervention seems to be not sufficient to restore FA concentrations to normality. This procedure, being easier and non-invasive compared with the evaluation of the FA pattern of the intestinal mucosa, could offer more potentiality for also evaluating therapeutic interventions in CD patients by using FA supplementation.

[PMID: 25050927 PMCID: PMC4113766 DOI: 10.3390/nu6072718] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/12/2014] [Revised: 05/13/2014] [Accepted: 07/07/2014] [Indexed: 02/07/2023] Open
Abstract
Celiac disease (CD) is a lifelong condition and it often involves impaired nutrition, wide spectrum of symptoms and it requires constant dietetic treatment. The impact of the gluten-free diet on patients’ nutritional status and on the other biochemical parameters is being widely investigated. In this article we looked into particular risk factors that might lead to increased prevalence of atherosclerosis in CD patients, including nutritional status, gluten-free diet, lipids profile and concomitant disease—type 1 diabetes mellitus. Here, we present the current data and research on these risk factors of atherosclerosis with respect to celiac disease.

Potential coeliac disease in Type 1 diabetes mellitus: does a positive antibody lead to increased complications? Nutr Metab Cardiovasc Dis 2014; 24:378-383. [PMID: 24393392 DOI: 10.1016/j.numecd.2013.09.005] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/17/2012] [Revised: 08/12/2013] [Accepted: 09/03/2013] [Indexed: 10/26/2022]
Abstract
BACKGROUND AND AIMS Coeliac disease (CD) is more common in people with Type 1 diabetes and is associated with poorer glycaemic control, lipid profiles, nephropathy and retinopathy. Potential CD (positive serology but normal duodenal biopsy) is associated with neuropathy but patients with coexisting Type 1 diabetes were excluded. The aim was to determine whether potential CD is associated with increased microvascular complications in patients with Type 1 diabetes. METHODS AND RESULTS Four groups were recruited; 1) patients with Type 1 diabetes and potential CD, 2) patients with Type 1 diabetes and newly identified CD, 3) patients with Type 1 diabetes alone and 4) patients with CD alone. Glycaemic control, quality of life, lipid profile and microvascular complication rates were examined. As many as 76 individuals were included in the study: 22 in group 1, 14 in group 2, 24 in group 3 and 16 in group 4. There were no differences in age, gender, BMI and diabetes duration between the groups. Patients in group 1 had significantly lower total cholesterol compared to group 3 (p = 0.003) but higher than group 2 (p = 0.027). There were no significant differences in HbA1c, HDL cholesterol, cholesterol:HDL ratio, creatinine, quality of life scores or prevalence of neuropathy between individuals in group 1 and the other groups. CONCLUSIONS This is the first study to assess the effects of potential CD in patients with Type 1 diabetes. It appears that an enteropathy is required as well as antibody positivity in order to increase the risk of diabetes related complications. This pilot data requires further longitudinal validation.

Early elevation of albumin excretion rate is associated with poor gluten-free diet adherence in young people with coeliac disease and diabetes. Diabet Med 2014; 31:208-12. [PMID: 24117620 DOI: 10.1111/dme.12329] [Citation(s) in RCA: 29] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/06/2013] [Revised: 08/06/2013] [Accepted: 09/19/2013] [Indexed: 12/18/2022]
Abstract
AIMS There are conflicting data on microvascular complications in coexisting Type 1 diabetes and coeliac disease. We compared complications rates in youth with or without coeliac disease and examined the association between gluten-free diet adherence and complications. METHODS This was a comparative study of adolescents (2510 without coeliac disease, 129 with coeliac disease); 60 (47%) did not adhere to a gluten-free diet--defined as elevated anti-tissue transglutaminase or endomysial immunoglobulin A titres. Retinopathy was detected using 7-field fundal photography and albumin excretion rate by timed overnight urine collections, with early elevation defined as albumin excretion rate ≥ 7.5 μg/min. Logistic regression was used to examine the association between complications and explanatory variables, including coeliac disease vs. no coeliac disease, gluten-free diet adherence vs. non-adherence, diabetes duration and HbA1c . RESULTS Median age at last assessment was 16.5 years. Those with coeliac disease vs. those without were younger at diabetes diagnosis (7.1 vs. 8.6 years, P < 0.001) and had longer diabetes duration (9.3 vs. 7.2 years, P < 0.001). HbA1c was lower in those with coeliac disease vs. those without (67 vs. 70 mmol/mol, 8.3 vs. 8.6%, P = 0.04) and adherence to a gluten-free diet vs. non-adherence (66 vs. 72 mmol/mol, 8.2 vs. 8.7%, P = 0.003). There were no differences in complication rates between those with coeliac disease vs. those without (retinopathy 22 vs. 23%, elevated albumin excretion rate 31 vs. 28%). Non-adherence to a gluten-free diet was associated with elevated albumin excretion rate (40 vs. 23%, P = 0.04). In multivariable logistic regression, elevated albumin excretion rate was associated with non-adherence to a gluten-free diet (odds ratio 2.37, 95% CI 1.04-5.40, P = 0.04) and diabetes duration (odds ratio 1.13, 95% CI 1.02-1.25, P = 0.03), but not HbA1c . CONCLUSIONS While glycaemic control is better in patients with coeliac disease, non-adherence to a gluten-free diet is associated with elevated albumin excretion rate. The possible protection of a gluten-free diet on complications warrants further investigation.

Abstract
AIM The aim of this study was to examine mortality in patients with both type 1 diabetes (T1D) and coeliac disease (CD). METHODS Between 1969 and 2008, we identified individuals with CD through biopsy reports from all pathology departments (n = 28) in Sweden. T1D was defined as a diagnosis of diabetes recorded in the Swedish National Patient Register between 1964 and 2009 in individuals aged ≤ 30 years. During follow-up, we identified 960 patients with both T1D and CD. For each individual with T1D and CD, we selected up to five subjects with T1D alone (i.e. no CD), matched for sex, age and calendar period of diagnosis, as the reference group (n = 4608). Using a stratified Cox regression analysis with CD as a time-dependent covariate, we estimated the risk of death in patients with both T1D and CD compared with those with T1D alone. RESULTS Stratifying for time since CD diagnosis, CD was not a risk factor for death in patients with T1D during the first 5 years after CD diagnosis [hazard ratio (HR) 0.87, 95% confidence interval (CI) 0.43-1.73], but thereafter the HR for mortality increased as a function of follow-up time (5 to < 10 years, HR 1.44, 95% CI 0.74-2.79; 10 to <15 years, HR 1.88, 95% CI 0.81-4.36). Having a CD diagnosis for ≥ 15 years was associated with a 2.80-fold increased risk of death in individuals with T1D (95% CI 1.28-6.12). CONCLUSION A diagnosis of CD for ≥ 15 years increases the risk of death in patients with T1D.

Type 1 diabetes and celiac disease: The effects of gluten free diet on metabolic control. World J Diabetes 2013; 4:130-134.

Abstract
Type 1 diabetes mellitus is associated with celiac disease, with a prevalence that varies between 0.6% and 16.4%, according to different studies. After a diagnosis of celiac disease is confirmed by small bowel biopsy, patients are advised to commence a gluten-free diet (GFD). This dietary restriction may be particularly difficult for the child with diabetes, but in Europe (and in Italy) many food stores have targeted this section of the market with better labeling of products and more availability of specific GFD products. Treatment with a GFD in symptomatic patients has been shown to improve the symptoms, signs and complications of celiac disease. However, the effects of a GFD on diabetic control are less well established. Initial reports of improved hypoglycemic control were based on children who were diagnosed with celiac disease associated with malabsorption, but there have subsequently been reports of improvement in patients with type 1 diabetes with subclinical celiac disease. There are other studies reporting no effect, improved control and an improvement of hypoglycemic episodes. Moreover, in this review we wish to focus on low glycemic index foods, often suggested in people with type 1 diabetes, since they might reduce postprandial glycemic excursion and enhance long-term glycemic control. In contrast, GFD may be rich in high glycemic index foods that can increase the risk of obesity, insulin resistance and cardiovascular disease, worsening the metabolic control of the child with diabetes. Hence, it is important to evaluate the impact of a GFD on metabolic control, growth and nutritional status in children with type 1 diabetes.

Type 1 diabetes and celiac disease in adults: glycemic control and diabetic complications. Acta Diabetol 2013; 50:319-24. [PMID: 22539236 DOI: 10.1007/s00592-012-0395-0] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2012] [Accepted: 04/04/2012] [Indexed: 12/17/2022]
Abstract
The prevalence of celiac disease (CD) in patients with type 1 diabetes mellitus (T1DM) is 4.5 %. Objective of the study is to investigate (1) the course of glycemic control at CD diagnosis and after the initiation of a gluten-free diet (GFD) in T1DM patients; (2) the prevalence of diabetic complications in T1DM patients with adult onset of CD. In 20 hospitals in the Netherlands, we identified T1DM patients diagnosed with CD at adult age. We retrospectively collected glycated hemoglobin (HbA1c) levels before CD diagnosis, at CD diagnosis, and the most recent HbA1c levels as well as the presence of nephropathy and retinopathy. The control group consisted of patients with T1DM and negative CD serology matched for age, gender, T1DM duration, and HbA1c levels. Thirty-one patients were eligible with a median duration of T1DM and CD of 27 years (IQR 14-37) and 3 years (IQR 1-8), respectively. The matched control group consisted of 46 patients. HbA1c levels at the moment of CD diagnosis were 7.5 % (IQR 7.1-8) [58 mmol/mol] and at the most recent visit 7.4 % (IQR 6.9-7.9, P = 0.15) [57 mmol/mol] indicating no difference. Prevalence of retinopathy was lower in T1DM + CD group compared with controls, (38.7 vs 67.4 %, P < 0.05), whereas no difference in the prevalence of nephropathy was found between the groups (P = 0.09). In conclusion, T1DM + CD patients have less retinopathy compared to T1DM patients without CD. A GFD possibly favorable affects the development of vascular complications in T1DM patients.

Abstract
Objective The purpose of this study was to investigate screening practices for celiac disease in patients with type 1 diabetes across North America. The research question investigated was whether diabetes centers screen for celiac disease in type 1 diabetes more frequently than other facilities. Research Design and Methods A survey with 27 questions on screening practices for celiac disease in patients with type 1 diabetes was designed by experts in celiac disease and diabetes. Surveys were sent by email to diabetes educators and dietitians throughout the United States and Canada between December 2010 and May 2011. Results There were 514 respondents from 484 endocrine clinics, diabetes clinics, private practices, community nutrition centers, and inpatient centers. Thirty-five percent of work locations screened for celiac disease, with endocrine clinics reporting screening at the highest frequency (80%). Tissue transglutaminase was the most common screening test used. The most frequently recommended treatment of confirmed celiac disease was a gluten-free diet. However, only 71% of respondents recommended biopsy in patients with positive serologies. Most respondents (55.3%) reported that the gluten-free diet resulted in symptom improvement in the majority of patients. Conclusions Staff at endocrine clinics were more likely to suggest screening for celiac disease in patients with type 1 diabetes. Both low screening frequency as well as inconsistency in management of positive celiac disease serological tests indicated an increase in education regarding celiac disease in patients with type 1 diabetes is required. In addition uniform guidelines should be developed.

A population-based study of the risk of diabetic retinopathy in patients with type 1 diabetes and celiac disease. Diabetes Care 2013; 36:316-21. [PMID: 22966098 PMCID: PMC3554314 DOI: 10.2337/dc12-0766] [Citation(s) in RCA: 57] [Impact Index Per Article: 5.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2012] [Accepted: 07/19/2012] [Indexed: 02/03/2023]
Abstract
OBJECTIVE Celiac disease (CD) is associated with type 1 diabetes (T1D). In the current study, we examined whether CD affects the risk of diabetic retinopathy (DRP) in patients with T1D. RESEARCH DESIGN AND METHODS This was a population-based cohort study. Through the Swedish National Patient Register, we identified 41,566 patients diagnosed with diabetes in 1964-2009 and who were ≤30 years of age at diagnosis. CD was defined as having villous atrophy (Marsh stage 3) according to small intestinal biopsies performed between 1969 and 2008, with biopsy reports obtained from Sweden's 28 pathology departments. During follow-up, 947 T1D patients had a diagnosis of CD. We used Cox regression analysis with CD as a time-dependent covariate to estimate adjusted hazard ratios (aHRs) for DRP in patients with T1D and CD and compared them with patients with T1D but no CD. RESULTS Duration of CD correlated with the risk of DRP. When results were stratified by time since CD diagnosis, individuals with T1D and CD were at a lower risk of DRP in the first 5 years after CD diagnosis (aHR 0.57 [95% CI 0.36-0.91]), followed by a neutral risk in years 5 to <10 (1.03 [0.68-1.57]). With longer follow-up, coexisting CD was a risk factor for DRP (10 to <15 years of follow-up, aHR 2.83 [95% CI 1.95-4.11]; ≥15 years of follow-up, 3.01 [1.43-6.32]). CONCLUSIONS Having a diagnosis of CD for >10 years is a risk factor for the development of DRP in T1D. Long-standing CD in patients with T1D merits intense monitoring of DRP.
