  • Title: Lymphoid nodular hyperplasia and cow's milk hypersensitivity in children with chronic constipation.
    Author: Turunen S, Karttunen TJ, Kokkonen J.
    Journal: J Pediatr; 2004 Nov; 145(5):606-11. PubMed ID: 15520758.
    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.
