[Antigliadin antibodies (AGA) in the various stages of celiac disease in children].

Antigliadin antibodies (AGA), both IgA and IgG, were studied in the serum of 84 coeliac children during the various stage (Diagnosis, GFD, Challenge) and in 29 healthy children, with a micro-ELISA technique. The results demonstrated the presence of AGA in the serum of coeliac children and a different behaviour between the two Ig-classes in the various stages of the disease. During acute phase both classes were present at high titre. When gluten was withdrawal from the diet, while the titre of IgA fell rapidly since the first month, the IgG titre decreased slowly and raised the normal limits after six months. If the children didn't observe a corrected GFD, the serum AGA titres remained at high levels. During challenge, while IgG raised since the early days, IgA titres raised later, when the intestinal damage became important. The explanation of this different behaviour could be that AGA-IgA are derived from gut mucosa, on the contrary AGA-IgG are not synthesised in the intestine. We believe that serum AGA seem to be good markers of the immune reaction in the intestine triggered by gluten. Furthermore we conclude that the assay of AGA in the serum of coeliac patients is: 1) high sensible and specific method; 2) the most important screening test for intestinal biopsy; 3) the most important test for diagnosis and follow-up of CD; 4) the test which could substitute 1 or 2 intestinal biopsies of the ESPGAN protocol.

[Cisapride efficacy in gastroesophageal reflux in children].

In the last years gastroesophageal reflux disease received more attentions, due to an improving in diagnostic techniques. Motility disorders, such as reduced competence of lower esophageal sphincter, motor esophageal disorders, delayed gastric emptying are important factors in the pathogenesis of the disease. Therefore therapy using prokinetic agents has been considered useful. A variety of drugs such as bethanecol, metoclopramide and domperidone have been used. There are conflicting report on the effects of these drugs and it should also be emphasized that they are not devoid of side effects related to dopamine antagonism. Recently cisapride, prokinetic agent which acts through facilitation of acetylcholine release, has been considered effective and well tolerate drug for the treatment of gastroesophageal reflux disease. In this view we investigated the effects of oral administration of cisapride in 12 children (age range 3-40 months), 7 females and 5 males, suffering from gastroesophageal reflux disease diagnosed on the bases of: clinic criteria, barium swallow radiological examination, 24-hour intraesophageal pH monitoring. After diagnosis a treatment with cisapride (1 mg/kg/die) before feedings for 8 weeks was started in all children. At the end of the trial clinical assessment and 24-hour intraesophageal pH test were performed. Clinical assessment was determined through weight, length and a clinical score calculated using the following parameters: regurgitation, vomiting, irritability, nocturnal weeping, meteorism, respiratory complaints. The total score was evaluated at diagnosis and during the follow-up (1st, 2nd, 4th and 8th week).(ABSTRACT TRUNCATED AT 250 WORDS)

[Allergy to cow's milk proteins: the authors' personal cases (clinical characteristics, diagnostic methodology and prospective follow-up)].

Because of specific laboratory tests are lacking, diagnosis of cow's milk allergy is always made on the basis of improvement after cow's milk protein withdrawal from diet and relapsed after challenge test. However personal and familial anamnesis, supported by few simple laboratory tests (peripheral blood and stool eosinophiles, hemoccult), are important tools for diagnosis. In this work we report the clinical findings of 68 children, suffered from cow's milk allergy, observed in the last 10 years. Children were divided into three groups on the basis of challenge response: Group 1 consisting of children with averse reaction occurred within the first hour after the administration of cow's milk protein (IgE-mediated reaction, 1st class as Gell-Coombs classification); Group 2 consisting of children with averse reaction occurred between 2nd and 12th hour (1st-3rd class as Gell-Coombs classification); Group 3 consisting of children with averse reaction occurred after 24 hours the administration of cow's milk proteins (4th class as Gell-Coombs classification). Auxological parameters show that while weight is widely involved, particularly in children of group 3, height is interested only in children with prolonged diarrhoea. Cow's milk protein withdrawal from diet determine a rapid normalization of weight increment rate, more evident in children over 25th centile. Height rise up normal values slowly without any differences between children below and over 25th centile. At the age of two years 57 children (83%) became tolerant to cow's milk proteins and after 5-year follow-up in 3 children (4.4%) only persisted cow's milk allergy. All these children presented the IgE-mediate clinical form.

[A case of severe malnutrition due to Ascaris lumbricoides infestation in a boy].

The authors report a case of a child three years old, with severe malnutrition as complication of Ascaris lumbricoides infection. Intestinal nematodes infect many of the world's children and constitute a formidable public health problem. The infected children may suffer nutritional deficits, serious illness and occasionally death. Although infestation is uncommon in our country, it should be considered in children with low social life.
