[Intraepithelial lymphocytes in celiac disease].

Coeliac disease (CD) is a permanent intolerance to gluten that provokes alterations in the mucosa of the small intestine. The disease can usually be controlled by excluding gluten from the diet. CD is immunologically-mediated, with a strong linkage to certain HLA alleles and a permanently altered intraepithelial lymphocytes (IEL) pattern. The development of a flow cytometric technique for the evaluation of IEL subsets has increased our understanding of these alterations and has prepared the ground for its clinical application. Our experience shows that this procedure has excellent sensitivity and specificity in the diagnosis of CD and that it is particularly useful in the evaluation of atypical presentations of the disease. The present article reviews our experience in the diagnosis of CD and discusses some of the hypotheses that have been put forward on the possible role of IEL in its pathogenesis.

[A comparative analysis of diagnostic methods for Helicobacter pylori infection in children].

OBJECTIVE: The aim of this study was to investigate the usefulness of five diagnostic tests for Helicobacter pylori (Hp) infection in children. PATIENTS AND METHODS: Sixty-five children with epigastric pain, recurrent abdominal pain, regurgitation, diarrhoea, anemia and insulin-dependent diabetes mellitus were investigated. Endoscopic biopsies from gastric antrum were performed and examined by the urease rapid test, histological examination and microbiological culture. An ELISA was used to detect specific IgG and anti-Hp. A carbon urea breath test was performed in 58 patients. RESULTS: Fifty-three patients were infected with Hp. The endoscopy appearance revealed nodularity in antral mucosa in 42 (79%) and erosions in 1 patient. The histology showed gastritis in all patients infected and Hp was identified in 46. The urease rapid test was positive in 96% and the culture positive in 89% of the patients infected. IgG antibodies to Hp were detected in 67% of the patients infected and the carbon urea breath test was positive in 96%. Twelve children were Hp negative, two of them having gastritis without Hp by histology. In the urease rapid test 3 false-positive results were detected and 1 false positive was found in the cultures. All Hp negative patients had negative results in the carbon urea breath test and were negative for IgG antibodies to Hp. CONCLUSIONS: The carbon urea breath test has a high sensitivity and specificity for the diagnosis of Hp infection and allows the selection of candidates for endoscopy.

[Study of intestinal permeability in celiac disease with 51 Cr-EDTA].

Intestinal permeability was studied in a group of 10 children diagnosed of coeliac disease either when they presented an intestinal villi atrophy while receiving a gluten-containing diet and after, when they had a normal mucosa with the withdrawal of gluten from the diet. Ten healthy children served as controls. The 51 Cr-EDTA (51 Cr-ethylenediaminetetraacetate) was used as probe molecule and it was administered orally. Its urinary excretion showed clear differences between patients with an altered intestinal biopsy and those with a normal histopathology. The excretion of 51 Cr-EDTA remained elevated in celiac patients with a gluten-free diet and normal villi.

[Cholelithiasis in children: apropos of 14 cases].

Between 1980 and 1990, we have diagnosed fourteen cases of cholelithiasis in children at our hospital. Abdominal pain was the most common symptom. Diagnosis was made by abdominal ultrasonography in all of the cases. Risk factors were found in 4 children. Family history was present in four patients. The treatments performed included cholecystectomy in five cases, extracorporeal lithotripsy in one case and a dietary regimen with regular clinical reviews in eight patients.

[Caustic esophagitis in children].

Treatment of caustic ingestion in children is a difficult and controversial problem which has not yet to be resolved. Here we report the evolution of fourteen children with esophageal injury after caustic ingestion that were treated with steroids at high-doses, nasogastric intubation and antibiotics. An early esophagoscopy was performed in all patients. Four patients developed esophageal strictures, three of which were mild and subsequent dilatation was successful. Only one patient was referred to surgery. We think that although it cannot be established, the use of high-dose of steroids and nasogastric intubation may be helpful for children with caustic esophagitis. We conclude that early endoscopy is useful to evaluate the severity of the lesions and to establish the necessity for treatment.

[Duodenal ulcer in children. Apropos of 28 cases].

We present 28 children, 4 to 14 year-old, with duodenal ulcer; there were 21 males and 7 females. In 16 cases, after stimulation with pentagastrin, basal pepsinogen I (PG1), basal gastrinemia and basal acid output (BAO) and maximal acid output (MAO) were measured. Compared to controls, the mean levels of PG1 and gastrin were significantly higher in the patients; 12 children (80%) had high levels of PG1 and the remaining 3 (20%) had normal levels. The blood group O was the most prevalent: 64% of the cases.
