ABSTRACT
OBJECTIVES: Children with type 1 diabetes (T1D) are not included in guidelines regarding diagnosis criteria for celiac disease (CD) without a diagnostic biopsy, due to lack of data. We explored whether tissue transglutaminase antibodies (anti-tTG) that were ≥ 10 times the upper limit of normal (10× ULN) predicted CD in T1D. METHODS: Data from the Swedish prospective Better Diabetes Diagnosis study was used, and 2035 children and adolescents with T1D diagnosed between 2005-2010 were included. Of these, 32 had been diagnosed with CD before T1D. The children without CD were repeatedly screened for CD using anti-tTG antibodies of immunoglobulin type A. In addition, their human leukocyte antigen (HLA) were genotyped. All children with positive anti-tTG were advised to undergo biopsy. Biopsies were performed on 119 children and graded using the Marsh-Oberhüber classification. RESULTS: All of the 60 children with anti-tTG ≥10x ULN had CD verified by biopsies. The degree of mucosal damage correlated with anti-tTG levels. Among 2003 screened children, 6.9% had positive anti-tTG and 5.6% were confirmed CD. The overall CD prevalence, when including the 32 children with CD before T1D, was 7.0% (145/2035). All but one of the children diagnosed with CD had HLA-DQ2 and/or DQ8. CONCLUSIONS: As all screened children and adolescents with T1D with tissue transglutaminase antibodies above 10 times the positive value 10x ULN had CD, we propose that the guidelines for diagnosing CD in screened children, when biopsies can be omitted, should also apply to children and adolescents with T1D as a noninvasive method.

Introduction: Percutaneous endoscopic gastrostomy (PEG) is the method of choice for long-term enteral feeding for patients with swallowing disorders and normal gut function. There is limited data regarding the demographics and clinical characteristics of patients from whom PEG was removed. Patients and methods: We performed a retrospective analysis of all consecutive adult patients who underwent first placement of PEG between 1 August 2013 and 31 December 2015 at Karolinska University Hospital in Stockholm, Sweden. Results: In total, 495 PEG were inserted in 495 patients during the study period, 56% male, mean age at insertion 67 years (range 19-95). Most patients belonged to the neurologic group (52%), followed by the oncologic (32%), another diagnosis (9%) and trauma (7%). Major complications occurred in 10 (2.0%) patients. There were no differences in the age or BMI of patients with either minor or major complications but both parameters were risk factors in terms of survival. PEG was removed from 165 (33.3%) patients, most of them from the oncology group, due to the improvement of general status of patients after specific oncologic treatment. Conclusion: Increased age and low BMI were identified as risk factors for mortality but did not correspond with the rate of complications. Antibiotic prophylaxis with sulfamethoxazole and trimethoprim provides good protection for patients with PEG.
