ABSTRACT
AIM: To find out the extent to which children at 10-11 y of age suffer from various gastrointestinal complaints and how often a food-induced or other diagnostic disorder might be assessed behind them, we carried out a population-based survey of 404 children in a rural Finnish town. METHODS: A questionnaire filled in retrospectively by their parents was used to describe the frequency of various abdominal symptoms during the previous 2 y and to select the symptomatic subjects for closer clinical examination. In the clinical investigation of the children, an elimination challenge with milk protein and lactose intolerance tests, as well as endoscopic examinations in selected cases and blood tests, were performed. RESULTS: In all, 110 (27%) subjects reported some gastrointestinal (GI) complaints during the last 2 y; 64 (16%) meeting the Apley criteria for recurrent abdominal pain. A specific organic or functional disorder was found in 26 subjects (6%), two having no GI symptoms. Milk protein intolerance was the most common specific disorder diagnosed in nine subjects (2.2%), followed by lactose intolerance in eight (2%), coeliac disease in five (1.2%) and Helicobacter pylori infection in three (0.7%). An endoscopic examination performed on 17 subjects (4.2%) and a colonoscopy on three revealed significant findings in 11; lymphonodular changes being most common, occurring in five subjects. Subjects with milk protein-induced disorders showed significantly lower IgA-class antibodies to milk and its fractions than the non-symptomatic controls. Chronic diseases, short breastfeeding, GI problems and food intolerance during the first year of life were observed as significant risk factors in determining whether a subject belonged to the group experiencing any GI complaints. CONCLUSION: We conclude that in one in five of those with any, even mild, GI complaints we were able to assess a specific organic disease; milk-induced disorders being most common. A milk protein and/or lactose load test, completed in some cases with an endoscopic examination, would help in assessing a proper individual diagnosis.

OBJECTIVE: To evaluate the role of food habits and nutrient intake in children with functional gastrointestinal disorders (FGIDs) considering their association with psychosocial factors. DESIGN: Cross-sectional. SETTING: A rural town in Mid-Western Finland. SUBJECTS: After excluding organic gastrointestinal (GI) disorders, a total of 49 children with FGID and 78 control children without GI symptoms from a cohort of 422 children were studied. METHODS: Food frequency questionnaire, GI-symptoms questionnaire and the Child Behaviour Check List (CBCL) filled in by parents together with their child, and 24-h dietary recall and anthropometric and haematological measurements. RESULTS: Compared to control children, fewer children with FGID had daily family dinner (77 vs 91%, P = 0.030) and they used less often vegetables (P = 0.023), fruits (P = 0.027) and berries (P = 0.011), but more often ice cream (P = 0.018) and soft drinks (P = 0.027) and had a higher sucrose intake (9 vs 7E%, P = 0.032) and lower lactose intake (27 vs 36 g, P = 0.001). Reported food-related symptoms were more common among FGID group (69 vs 11%), as well as restricted milk use (31 vs 0%). Children with FGID had higher total problem scores in CBCL (P=0.002), and the behavioural/emotional problems associated with occurrence of FGID (OR 1.04, 95% CI 1.07-1.076) as did the sugar intake (OR 1.1, 95% CI 1.004-1.215). CONCLUSIONS: This population-based study suggests that school-aged children with FGIDs have less-organized food habits and higher milk avoidance, and they display internalizing psychological characteristics.

OBJECTIVES: Cow's milk protein-sensitive enteropathy (CMSE) may persist in children to school age. We sought to define the morphologic and immunohistochemical features of persistent CMSE. STUDY DESIGN: We studied 15 children with a definite diagnosis of CMSE on the basis of a blind challenge, 12 children with suspected cases of CMSE, 11 children with celiac disease, and 12 control children. RESULTS: Typical findings in children with CMSE were endoscopically visible lymphonodular hyperplasia of the duodenal bulb and lymphoid follicles without villous atrophy in biopsy samples. The patients with definite CMSE showed significantly increased densities of intraepithelial T cells skewed clearly to gammadelta(+) cells, compared with the control patients but fewer than in the patients with celiac disease. The study children showed no aberrant upregulation of HLA-DR expression in the duodenal mucosa, and the prevalence of HLA DQ2 antigen among them was equal to that in the control children. CONCLUSIONS: Our observations corroborated the claim that CMSE at school age is an identifiable clinical entity. Immunohistochemical findings suggest the abrogation of antigen tolerance locally on the gastrointestinal mucosa. A careful clinical assessment that includes a long elimination-challenge test supported by typical endoscopic and histologic findings form the basis for diagnosis.
