Abstract: To survey clinical characteristics at diagnosis for children diagnosed with Type 1 diabetes during 25 years in the south-east part of Sweden we included all 1903 children <16 years of age and who had been diagnosed between 1977 and 2001 in the south-east region of Sweden. A nurse or doctor in the diabetes team obtained information from medical records. Over the 25 years the mean duration of symptoms prior to diagnosis was 17.8 ± 26.4 days and the mean glucose level at diagnosis was 23.6 ± 9.7mmol/l. Three percent of the children (n = 50) had a pH value ≤ 7.1. The youngest children (0–5 years) had shorter duration of symptoms, lower blood-glucose levels and less often had ketonuria than the oldest children (11–15 years) but more often suffered from infections prior to diagnosis. The proportion of children diagnosed in the group 0–5 years of age increased over the study-period, apart from the last 5 years, while children with pH value ≤ 7.3 decreased significantly as did the proportion of children with ketonuria or infection. The clinical characteristics at diagnosis of diabetes are heterogeneous, especially in the oldest age group. Some characteristics varied with time. [Copyright &y& Elsevier]

In coeliac disease (CD) there is a gluten-induced small bowel enteropathy leading to malabsorption of various nutrients, vitamins and trace elements. Low levels of serum zinc have been reported in adults with untreated CD. In the present study we related the serum concentration of zinc to the morphology of the small bowel mucosa in 58 children, all under 4 years of age and under investigation for coeliac disease. The mean serum concentration of zinc (mean ± SD; μmol/L) was significantly lower in children with untreated CD (9.7 ± 2.0) (n = 11) compared to non-coeliac children without enteropathy (15.1 ± 2.3) (n = 16) (p < 0.001), coeliac children on a gluten-free diet without enteropathy (14.2 ± 1.6) (n = 14) (p < 0.001), coeliac children on gluten challenge with enteropathy (14.1 ± 2.1) (n = 12) (p < 0.001) and coeliac children on gluten challenge without enteropathy (13.8 ± 1.9) (n = 6) (p < 0.005). Conclusion: Serum zinc concentration is decreased in untreated coeliac children with enteropathy and normalizes on gluten-free diet. A low serum zinc value in a child being investigated for possible CD on clinical grounds can thus be used as a complementary marker for enteropathy indicating further investigation with small bowel biopsy. The hypothetical role of zinc in the pathogenesis of CD is discussed. [ABSTRACT FROM AUTHOR]

Background and aim: Diagnosis of coeliac disease is based on the demonstration of enteropathy in a small bowel biopsy. Correct diagnosis is of utmost importance, since the need for dietary management is life long, and inadequate treatment may lead to potentially serious complications. The Swedish Working Group for Paediatric Coeliac Disease has published guidelines for the diagnosis of childhood coeliac disease. The present questionnaire was designed in order to create the basis for revision of those guidelines. Methods: In 2004, a nationwide questionnaire concerning current diagnostic routines was sent to all 45 paediatric clinics performing small bowel biopsy. All clinics responded. Results: All clinics base their diagnosis on small bowel biopsy findings at presentation. Furthermore, in 24 (53%) of the clinics, children with suspected coeliac disease are investigated by small bowel biopsy both at presentation and follow-up while on a gluten-free diet. Eighteen (40%) of the clinics employ a different diagnostic routine for children under 2 y of age than for those older than 2 y. All clinics use coeliac serological testing at various stages of the diagnostic procedure.Conclusion: All Swedish paediatric clinics perform a small bowel biopsy at presentation in children with suspected coeliac disease, and the majority of clinics perform a second biopsy when the child is on a gluten-free diet. Serological testing is frequently used as a diagnostic aid and in the monitoring of the disease while on a gluten-free diet. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented in response to the article "Coeliac disease is more common in children with high socio-economic status," by L. A. Whyte, S. Kotecha, W. J. Watkins, and H. R. Jenkins in the 2014 issue.

Background: Living with undiagnosed symptomatic coeliac disease is connected with deteriorated health, and persons with coeliac disease often wait a long time for their diagnosis. A mass screening would lower the delay, but its cost-effectiveness is still unclear. Our aim was to determine the cost-effectiveness of a coeliac disease mass screening at 12 years of age, taking a life course perspective on future benefits and drawbacks.Methods: The cost-effectiveness was derived as cost per quality-adjusted life-year (QALY) using a Markov model. As a basis for our assumptions, we mainly used information from the Exploring the Iceberg of Celiacs in Sweden (ETICS) study, a school-based screening conducted in 2005/2006 and 2009/2010, where 13,279 12-year-old children participated and 240 were diagnosed with coeliac disease, and a study involving members of the Swedish Coeliac Association with 1031 adult participants.Results: The cost for coeliac disease screening was 40,105 Euro per gained QALY. Sensitivity analyses support screening based on high compliance to a gluten-free diet, rapid progression from symptom-free coeliac disease to coeliac disease with symptoms, long delay from celiac disease with symptoms to diagnosis, and a low QALY score for undiagnosed coeliac disease cases.Conclusions: A coeliac disease mass screening is cost-effective based on the commonly used threshold of 50,000 Euro per gained QALY. However, this is based on many assumptions, especially regarding the natural history of coeliac disease and the effects on long-term health for individuals with coeliac disease still eating gluten.

Objective: We previously performed a population-based mass screening of coeliac disease in children aged 12 years in two birth cohorts resulting in 296 seropositive children, of whom 242 were diagnosed with coeliac disease after duodenal biopsies. In this follow-up study, we wanted to identify new cases in the screening population that tested negative-either converting from potential coeliac disease (seropositive but normal duodenal mucosa) or converting from seronegative at screening to diagnosed coeliac disease., Methods: All seropositive children were invited to a follow-up appointment 5 years after the screening with renewed serological testing and recommended endoscopic investigation if seropositive. Seronegative children in the screening study (n=12 353) were linked to the National Swedish Childhood Coeliac Disease Register to find cases diagnosed in healthcare during the same period., Results: In total, 230 (77%) came to the follow-up appointment, including 34 of 39 with potential coeliac disease. Of these, 11 (32%) had converted to coeliac disease. One new case was found in the National Swedish Childhood Coeliac Disease Register who received the diagnosis through routine screening in children with type 1 diabetes., Conclusions: There is a high risk of conversion to coeliac disease among those with potential disease. However, a negative screening test was associated with a very low risk for a clinical diagnosis within a follow-up period of 5 years., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Seventy years ago, the Swedish pediatrician Rolf Kostmann (1909-1982) was the first to report on a previous unknown lethal hereditary neutropenia in infants, Kostmann's disease. This essay presents the man behind the syndrome rather than focusing on the disease itself.

Aim: In 2012, revised criteria for diagnosing childhood coeliac disease were published by the European Society for Paediatric Gastroenterology, Hepatology and Nutrition and incorporated into the revised Swedish guidelines the same year. These made it possible, in certain cases, to diagnose coeliac disease without taking small bowel biopsies. This survey assessed the extent to which the new guidelines were implemented by Swedish paediatric clinics two years after their introduction., Methods: In October 2014, we distributed a paper questionnaire including five questions on diagnostic routines to the 40 paediatric clinics in university or regional hospitals in Sweden that perform small bowel biopsies., Results: All 36 (90%) clinics that responded used anti-tissue transglutaminase antibodies as the initial diagnostic test and some also used serological markers. Most clinics (81%) used endoscopy and took multiple duodenal biopsies, whereas only a few (19%) occasionally employed a suction capsule. Almost all clinics (86%) omitted taking small bowel biopsies in symptomatic children with repeatedly high coeliac serology and positive genotyping, thereby avoiding the need for invasive endoscopy under anaesthesia., Conclusion: The 2012 Swedish Paediatric Coeliac Disease Diagnostic Guidelines had been widely accepted and implemented in routine health care two years after their introduction., (©2018 Foundation Acta Paediatrica.

Background: The features of paediatric coeliac disease have changed in recent decades. We hypothesised that the age at diagnosis might continue to increase, whereas the severity of symptoms should decrease., Methods: In the present study, filed data on 1030 paediatric patients diagnosed with coeliac disease between 1973 and 2013 were analysed. The information available covered 99.8% of small bowel biopsies and included information on sex, age and clinical symptoms., Results: The age at diagnosis increased significantly, from a mean of 2.2 years during the first 10 years to 8.2 years in recent years. The proportion of children with severe symptoms declined from 92.8% to 78%, as did the proportion of biopsies characterised by severe pathology. In recent years, the monosymptomatic form of coeliac disease has been more common, and the number of patients detected at screening has increased. The frequency of patients with gastrointestinal symptoms, extra-intestinal symptoms, and failure to thrive and/or short stature at presentation decreased., Conclusions: The mean age of newly diagnosed patients has increased over the last 15 years. Currently, coeliac disease shows a less severe picture in terms of symptoms and intestinal pathology. Younger children suffer primarily from gastrointestinal symptoms and growth failure, and adolescents from extra-intestinal manifestations., (Copyright © 2015 Editrice Gastroenterologica Italiana S.r.l.
