MS manifests as growth failure, delayed puberty, cushingoid features, and hepatomegaly. The condition can be associated with complications like dyslipidemia, retinopathy, and nephropathy. The main objective of this study was to describe the magnitude of the condition, clinical features, management, and outcome of Sudanese children and adolescents with MS due to inadequate control of diabetes in our center. <b>Study Design and Methods:</b> This is a cross-sectional hospital-based study. All medical records of patients with MS were reviewed. Data, including demographics, clinical features, investigations, management, and outcome, were obtained. Patients were re-educated and management intensified then followed up. <b>Results:</b> Thirty-seven MS patients were enrolled in this study, with a male predominance of 59.5%. Neonatal diabetes was diagnosed in 5.4% of the patients, while others had T1DM. The median age at diagnosis of MS was 12 years. The diagnosis was based solely on clinical findings, including a history of prolonged unsatisfactory glycemic control, short stature, and hepatomegaly. Regarding the outcome, eight children (21.6%) were lost to follow-up, one patient died (2.7%), seven (18.9%) had a static condition, and those who showed improvement were 21 (56.8%). Signs of improvement were a decrease in liver size with or without an increase in growth velocity. Nephropathy was the most common associated complication; it was seen in 33.3% of our cohort. Some got it at a very young age. <b>Conclusions:</b> Despite many efforts that have been made to achieve better glycemic control in children with T1DM, MS still exists in our setting.

Participants and their caregivers completed the Vancouver Symptom Score (VSS) to assess bowel and bladder symptoms. BBD was defined as a total VSS score of 11 or greater. Logistic regression was used to identify potential factors associated with BBD and bother with symptoms. <b>Results:</b> In a group of 242 participants with T1D and 86 controls, 46% were male, and the median age was 11.0 years. The prevalence of BBD was found to be higher in participants with T1D at 21.5%, compared to 10.5% in controls. While irritative symptoms were most commonly reported in the T1D group with BBD, urinary incontinence caused the most bother. In the T1D group, poorer glycemic control was linked to a greater likelihood of BBD, while male sex and more severe symptomatology (such as urinary incontinence) were associated with greater bother related to these symptoms. <b>Conclusion:</b> There is a high prevalence of BBD in children with T1D compared to healthy controls. These data highlight the need for early identification and intervention for BBD in T1D. Proactive measures, such as routine screening and comprehensive T1D management with strict attention to glycemic control, are crucial to address the significant burden of BBD and improve overall health outcomes for children with T1D and their families.</p>","PeriodicalId":19797,"journal":{"name":"Pediatric Diabetes","volume":"2025 ","pages":"5294835"},"PeriodicalIF":5.6,"publicationDate":"2025-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12373478/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144964320","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The risk of developing celiac disease (CD) is 3-4 times higher in children with T1D. Guidelines recommend regular screening for transglutaminase antibodies (TgAbs) in T1D children. CD could be an additional burden for T1D children as both diseases affect food intake. We describe the screening practice for CD during the last 25 years in our outpatient clinic in children with T1D. <b>Methods:</b> We retrospectively analyzed the development of CD-specific antibodies in our children with T1D (diabetes onset since 1998). We did not routinely recommend endoscopy when CD-specific antibodies (TgAb, endomysium [EAb], and gliadin) were positive and patients had no CD-specific symptoms. <b>Results:</b> We analyzed 304 patients. In total 122 had CD-specific antibodies. In 98 of them, they disappeared after a short time or had been only slightly elevated. The diagnosis of CD was confirmed in 12. All 12 showed CD-specific symptoms, such as failure to thrive, anemia, hypoglycemia, or gastrointestinal problems. In six patients, even severely elevated EAb and/or TgAb disappeared on average after 7.1 years (range 4.9-13.5 years) on gluten-containing diet. The remaining six had antibodies without CD-specific symptoms by the end of the observation period. In this group the duration of antibody-positivity was 4 years (range 1.8-11.6 years). <b>Conclusion:</b> We conclude that even highly elevated CD-specific antibodies can disappear in children with T1D and that screening for CD-specific antibodies is therefore only useful in symptomatic children with T1D.</p>","PeriodicalId":19797,"journal":{"name":"Pediatric Diabetes","volume":"2025 ","pages":"4717290"},"PeriodicalIF":5.6,"publicationDate":"2025-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12334288/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144817291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
