Lithophagia as a clue for celiac disease: a case report and literature review

ABSTRACT

Lithophagia is a type of pica that might be resulted from Iron Deficiency Anemia [IDA]which is the frequent presenting signs of Celiac Disease [CD]. A 5-year-old child with a two year history of the lithophagia with a, refractory IDA, abdominal distention and constipation. The child did not grow well and had failure to thrive. With suspicion to CD, TTg IgA level was measured and due to an incearse of TTg IgA level the patients were undergone esophagogastrodeudonoscpy and jejunal biopsy. The biopsy showed severe villous atrophy and an increase in limphoplasma cells. Biopsy confirmed diagnosis of CD and glutten free diet was initiated finally. Six months after diagnosis and commencing the gluten free diet, the lithophagia and constipation in patient eradicated completely. IDA and failure to thrive were improved and the level of TTg IgA was reached to the normal. The case demonstrated the relationship between lithophagia and CD in anemia. Therefore, in the same cases such as our case should be considered CD as the most important causes of lithophagia
