Insights
Celiac disease (CD) affects 2.8% of children with short stature. Testing for CD with anti-tissue transglutaminase (TTG) antibodies is recommended for children with short stature, even without GI symptoms.
Area of Science:
- Pediatric Endocrinology
- Gastroenterology
- Immunology
Background:
- Short stature is a common pediatric concern.
- Celiac disease (CD) can present with various symptoms, including growth failure.
- Early diagnosis of CD is crucial for effective management and preventing long-term complications.
Purpose of the Study:
- To determine the prevalence of celiac disease in children presenting with short stature.
- To evaluate the utility of anti-tissue transglutaminase (TTG) antibody testing in this population.
Main Methods:
- A cohort of children with short stature (height > 2 SD below the mean) were assessed.
- Serum IgG anti-TTG antibody levels were measured using ELISA.
- Children with elevated antibodies underwent further investigations, including duodenal biopsy.
Main Results:
- Two out of 72 children (2.8%) with short stature had elevated IgG anti-TTG antibodies.
- Duodenal biopsies confirmed celiac disease in these children.
- Other findings included anemia (5.6%) and growth hormone deficiency (6.9%).
Conclusions:
- Celiac disease should be considered in the diagnostic workup of children with short stature, particularly those with height > 3 SD below the mean.
- Measurement of anti-TTG antibodies is a valuable tool in evaluating children with short stature, irrespective of gastrointestinal symptoms.
- The study highlights the importance of including CD screening in the routine evaluation of pediatric short stature.
Objective:
The aim of the present study was to determine the prevalence of celiac disease in children with short stature.
Methods:
In all children with short stature (height more than 2 SD below the mean for age and sex) and normal physical examination, attending Motahary pediatric clinic in Shiraz, Iran, from 2003 till 2005, work-ups were made to find a cause for their short stature and of course their serum was assayed for IgG anti-tissue transglutaminase (TTG) antibody by ELISA test, as a marker for CD.
Results:
There were 26 girls and 46 boys with mean age of 9.8 years. Routine work-up showed microcytic hypochromic anemia in four children (5.6%) and giardiasis in five (6.9%). GH stimulation test revealed GH deficiency in five children (6.9%). Elevated IgG anti-TTG antibody level was detected in two children (2.8%). Duodenal biopsies of these children were in favor of celiac disease.
Conclusion:
Although, the prevalence of CD in this study was not significantly different (P value = 0.14) from the prevalence rate in healthy blood donors in Iran, the findings emphasize the fact that CD must be considered in a child with short stature, especially if the height is more than 3 SD below the mean for sex and age, even in the absence of gastrointestinal symptoms. In conclusion, the measurement of anti-TTG antibody should be included in the diagnostic evaluation of children with short stature.
