OBJECTIVE: We have studied gastric emptying using real time ultrasound in 25 healthy children and 25 children with RGE. Our aim was to establish the time and mode of gastric emptying and the volume and the degree of antral dilation in both groups at baseline and after a test meal. We also evaluated the same parameters in the RGE cases after supplying a prokinetic. PATIENTS AND METHODS: The Bolondi technique was used to measure the basal antrum volume and emptying ratio, as well as the mode and final gastric emptying time at different time-points after a solid-liquid test meal. RESULTS: Patients with RGE have a clearly longer gastric emptying time with respect to the healthy subjects in both children less than one year of age (238 +/- 48.4 vs 176.3 +/- 36.7 minute; p = 0.03) and those 1-14 years old (206.3 +/- 48.2 vs 163.3 +/- 48.1 minutes, p = 0.03). An anomalous gastric emptying, similar to a broken line, can be observed in children suffering from RGE. In contrast, a progressive reduction of antrum dilation ration was seen in healthy children and not in patients with RGE. After cisapride, gastric volume goes down at all test times in RGE children. Therefore, a decrease in final gastric emptying time cannot be observed. CONCLUSIONS: Children suffering from RGE show an alteration in gastric emptying with a clearly greater time and an anomalous mode of emptying. The antrum remained dilated for longer periods after ingestion of test food.
We report the results of indirect immunofluorescent (IFI) detection of IgA and IgG antireticulin antibodies (IgA-ARA and IgG-ARA, respectively) in 283 serum samples from pediatric patients with coeliac disease (with and without gluten containing diets), patients with non-coeliac gastrointestinal disease, patients without gastrointestinal disease (control group) and patients with an increased risk for coeliac disease (diabetes mellitus, dermatitis herpetiformis or first grade relatives of coeliac patients). Our results indicate that IgA-ARA is a reproducible marker, with high positive (99-100%) and negative (100%) prediction values, when it is applied to children who have been on gluten containing diets for a long time (more than six months). The IgA-ARA measurement is not applicable in cases of selective IgA deficiency. Although IgG-ARA has a high predictive positive value, its low predictive negative value makes it a poor diagnostic tool. In the risk groups, our results suggest that these antibodies are useful in patient selection for intestinal biopsy.
We report a review of 20 children (14 males and 6 females) between 3 1/2-13 years of age (mean 9.7/ 12 years) with primary peptic ulcer disease, diagnosed by digestive fiberendoscopy. Endoscopy revealed 18 duodenal and 2 gastric ulcers. Positive family history was found in 45% of the patients. Abdominal pain was the most common presenting symptom and gastrointestinal bleeding was the only complication. The time before diagnosis was lesser than one month in 10%, between one to six months in 30% and more than months in 60% of patients. The follow-up period rate from three to 46 months (mean 14.9/12 months). Radiological study was performed in 18 patients and led 50% of false negative. A satisfactory response to mean treatment was found in all cases. Three patients related No patients required surgical treatment.
The authors value the parameters of diagnostic efficacy in a preliminary study of anti-endomysium antibodies (EmA), in the diagnostic and follow-up of patients with gluten sensitive enteropathy. The study was made with 84 subjects distributed into four groups. Group I consisted of 21 patients with gluten sensitive enteropathy (GSE) who were eating gluten at the time of diagnosis. Group II consisted of 20 patients with gluten sensitive enteropathy with different periods of time of gluten free diet. Group III consisted of 16 subjects with non-evolutive neuropathies and without intestinal disease. This group was considered as controls. Group IV consisted of 27 patients with toddler diarrhoea. The sensitivity, specificity, positive predictive value, negative predictive value and efficiency were 100%.
The authors reports the results of ELISA IgG and IgA antigliadin antibodies measurements in a study of 271 serum samples proceeding from celiac patients (with and without gluten containing diet) and control subjects. IgA antigliadin antibody measurement had the most specificity and positive predictive value, IgG antigliadin antibody measurement had the most sensitivity and negative predictive value. Our results point out that antigliadin antibodies are helpful in the diagnosis and management of celiac disease. Un the same manner, antigliadin antibodies are helpful to evaluate the adherence of patients to gluten-free diet.
