RESUMEN
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.
