THE IMPACT OF CELIAC DISEASE ON GROWTH AND DEVELOPMENT IN CHILDREN

Аннотация

Celiac disease is a chronic immune-mediated enteropathy triggered by gluten in genetically predisposed individuals. In children, the condition is of particular concern as it impairs nutrient absorption during critical periods of physical and cognitive development. This article comprehensively explores the impact of celiac disease on pediatric growth, musculoskeletal formation, neurological function, and emotional stability. It discusses pathogenesis, clinical manifestations, diagnostic strategies, and the transformative role of a gluten-free diet. The study emphasizes early diagnosis, long-term dietary compliance, and a multidisciplinary management strategy. Keywords: Celiac disease, gluten, growth delay, child development, gluten-free diet, malabsorption, pediatricnutrition.

In children, undiagnosed or unmanaged CD can significantly impair growth and development, leading to long-term consequences such as stunted height, bone deformities, and cognitive delays. The increasing prevalence of CD globally, particularly among children, highlights theimportance of early recognition and management. 2.Etiology and Pathogenesis Celiac disease is genetically linked, with HLA-DQ2 and HLA-DQ8 haplotypes present in over 95% of affected individuals. Upon ingestion of gluten, gliadin peptides are deamidated by tissue transglutaminase (tTG), enhancing their affinity to HLA molecules. This triggers T-cell- mediated inflammation, leading to villous atrophy, crypt hyperplasia, and intestinal permeability. The resulting mucosal damage causes impaired absorption of essential nutrients critical for growth. https://ijmri.de/index.php/jmsi volume 4,issue5,2025 768 3.Clinical Manifestations inChildren Symptomsin children may vary by age: -Infants: Chronic diarrhea, failure to thrive, abdominal distension -Toddlers: Irritability, anorexia, delayed speech -School-aged children: Short stature, delayed puberty, learning difficulties Extraintestinal signs include iron-deficiency anemia, dental enamel defects, dermatitis herpetiformis, and neurobehavioral disturbances. 4.DiagnosticCriteriaand Monitoring Diagnosis includes: -Serological testing: Anti-tTGIgA and EMAare gold-standard tests. -Endoscopicbiopsy: Confirms villousatrophy using Marsh classification. -Genetic testing: HLA-DQ2/DQ8 genotyping for unclear cases. -Anthropometry: Routinetracking of height-for-age, weight-for-age, and BMI percentiles. -Nutrient profiles: Iron, vitaminD, folate, and zincassessments. 5.Impact onGrowth and Development Duetonutrient malabsorption, CDcan cause: -Linear growth retardation (height-for-age below3rd percentile) -Weight stagnation orloss -Delayed bone age and lowbone mineral density -Impaired psychomotordevelopment and cognitivedelays -Increased risk ofdepression and anxiety Untreated CDduring growth years may result in permanently stunted adult height and skeletal immaturity. 6.Roleof Gluten-Free Diet in Recovery Alifelong, strict gluten-free diet (GFD) is theonly effectivetreatment. Clinical improvements areusually seen within months: -Growth parameters normalizein 6–12months -Gastrointestinal symptoms resolve quickly -Hematological markers recover (Hb, ferritin) -Neurodevelopmental progress resumes Nutritionalcounseling and supplementation (iron, calcium, vitaminD) are essential for full recovery. 7.Regional Challenges andRecommendations In developing regions likeCentral Asia: -Gluten-freefood availability islimited and costly -Publicand professional awareness is low -Screening programs arenot yet standardized Recommendations: -Introduce affordable gluten-free foodalternatives -Implement school health screening -Train pediatricians in early recognitionof CD https://ijmri.de/index.php/jmsi volume 4,issue5,2025 769 -Encourage publiceducation and food labeling policies 8.Conclusion Celiac disease has a profound and multifaceted impact on the health of children. Timely diagnosis, rigorous dietary compliance, and ongoing multidisciplinary support can reverse growth failure and allow children to achieve normal development milestones. A comprehensive public health approach is needed to improve early detection and management, particularly in under-resourced settings. 9.References 1. Fasano A, Catassi C. Celiac Disease.
