Abstract

OBJECTIVE:

To investigate the incidence of cow's milk allergy as evidenced by milk challenge and the findings of endoscopic and immunohistochemical examinations in children with chronic and refractory constipation.

STUDY DESIGN:

Thirty-five study subjects (mean age, 8.3 +/- 3.3 years; range, 3-15 years; 17 girls) and 15 control subjects (mean age, 11.7 +/- 3.2 years; range, 2-15 years; 9 girls) were studied by colonoscopy and a 4-week cow's milk elimination and challenge.

RESULTS:

Lymphoid nodular hyperplasia was the most prominent endoscopic finding in half of the subjects (46%), mostly occurring patchily in the transverse colon. Histologic findings other than lymphoid accumulation and mildly increased density of eosinophils were few. During the milk elimination and with supportive medication, 83% of subjects remitted. Constipation and/or other gastrointestinal or skin symptoms relapsed only in one third (34%) during the cow's milk challenge, these having significantly higher densities of intraepithelial gammadelta + T cells ( P <.001) in the biopsy samples of the terminal ileum as compared with the control subjects.

CONCLUSIONS:

We were able to find formal evidence for the presence of cow's milk allergy in children with chronic constipation.
