Very-low dose antacid in treatment of duodenal ulcer. Comparison with cimetidine.

Antacid (AA) in a very low dose (88 mmol/day) was compared to the standard 800-mg dose of cimetidine in healing duodenal ulcers. The influence of sex, age, symptom duration at entry, night pain, smoking, coffee consumption, and alcohol on ulcer healing was studied. The antacid was given in two different schedules: group I--20 ml 1 hr after breakfast and at bedtime; group II--10 ml 1 hr after breakfast and lunch and 20 ml at bedtime. Cimetidine (group III) was given in two divided doses: 400 mg 1 hr after breakfast and 400 mg at bedtime. Endoscopic control was performed after four weeks and, if necessary, after eight weeks of treatment. The healing rate after four weeks of treatment was, respectively, for groups I, II, and III, 45.5%, 55.8%, and 69.4% (group I = group II, and group III different from groups I and II). After eight weeks of treatment the healing rate was 61.5%, 80.8%, and 88.0% for groups I, II, and III, respectively (group II = group III, and group I different from groups II and III). Except for group I, smoking did not influence healing rate. Age, sex, symptoms at entry, night pain, and coffee consumption did not influence the treatment results. The authors concluded that the very low dose of magaldrate (88 mmol/day), when administered in three divided doses (10 ml after breakfast and lunch and 20 ml at bedtime) for eight weeks was as effective as 800 mg of cimetidine (400 mg twice a day) in healing duodenal ulcer.

[Histochemical study of the skeletal muscle in chronic alcoholism].

Twenty-two chronic alcoholic patients were assessed by neurologic examination and muscle biopsy. The patients manifested proximal muscular weakness to a variable extent. One case presented as an acute bout of myopathy, according to the Manual Muscle Test, MMT. The most prominent histologic feature observed was muscle atrophy (95.3%) better evidenced through the ATPase stain with the predominance of type II A fibers (71.4%). Lack of the mosaic pattern (type grouping) seen in 76% of the cases and an important mitochondrial proliferation with intrasarcoplasmatic lipid accumulation in 63% of the patients. In case of acute presentation of muscle weakness the pathological substrate is quite different, i.e. presence of myositis mainly interstitial characterized by lymphoplasmocytic infiltrate and several spots of necrosis like Zencker degeneration. Based on histologic criteria, our data suggest that: the main determinant of muscle weakness seen in chronic alcoholic patients is neurogenic in origin (alcoholic polyneuropathy); the direct toxic action of ethanol under the skeletal muscle is closely related to the mitochondrial metabolism; the so-called acute alcoholic myopathy has probably viral etiology.

[Importance of serum albumin values in nutritional assessment and inflammatory activity in patients with Crohn's disease].

BACKGROUND: The serum albumin concentration has frequently been regarded as an indicator of nutritional status, although the hypoalbuminemia may reflect an acute phase protein response during inflammation mediated by cytokines. Both hypoalbuminemia and malnutrition are observed in Crohn's disease. OBJECTIVES: To correlate the serum albumin values to disease activity and also to nutritional status in patients with Crohn's disease. PATIENTS/METHODS: Thirty six patients were studied. Nutritional status was assessed by anthropometry measures and inflammatory activity determined by Harvey's simple clinical index and erythrocyte sedimentation rate. RESULTS: No correlation was found between malnutrition and hypoalbuminemia. The serum albumin levels correlated inversely with the disease activity. Hypoalbuminemia was 100% sensitive for detection of disease activity. CONCLUSION: This study suggests that serum albumin concentration is a very sensitive marker of inflammatory activity and not good indicator of the nutritional status in Crohn's disease. It is necessary a suitable laboratorial parameter for routine nutrition assessment in patients with this inflammatory bowel disease.

Parasite and egg burden, hepatic collagen and histologic pattern of liver granulomas in selection III high and low antibody responder mice infected with Schistosoma mansoni.

Selection III mice have particular immunological characteristics: they are high (H III) or low (L III) antibody producer animals, yet both lines display similar T cell responses and macrophage activities. We submitted these mice to infection with Schistosoma mansoni to assess in vivo parasite and egg burden, hepatic collagen and cellular composition of granulomas in both lines. Titration of anti-Schistosoma IgG by ELISA showed remarkably higher values in H III line, at both studied periods (8th and 12th weeks post-infection). Nevertheless, the number of adult worms recovered from the portal system was similar in both lines, being not associated with anti-Schistosoma antibody levels. There is an increase in hepatic collagen from the 8th to the 12th weeks post-infection, which is paralleled by an increase in the number of eggs in the liver. This association apparently occurs at the same ratio in H III and L III animals. The most important difference found between the two lines was the outstanding contrast in terms of volume and eosinophil counts in the granulomas, with lesions from H III mice clearly being larger and containing more of these cells than LIII lesions.

Vestibular disorders caused by defective enzyme mechanisms in the small intestine.

A group of patients suffering from long periods of unsteadiness and presenting hyperreflexia in response to torsion swing and/or caloric stimulations were found to have abnormal results in glucose and lactose tolerance tests, but normal or reduced insulin liberation. Biopsies of the jejunal mucosa have shown abnormal enzyme activity or deficiencies in transport mechanisms. The use of a diet suited to each specific deficiency resulted in a high percentage of relief from the vestibular symptoms of these patients.

Murine schistosomiasis mansoni: estimation on some immunohistological parameters of small bowel granulomas and renal parenchyma.

One hundred and twenty five mice were divided into three groups: uninfected (I), and infected with 30 (II) and 60 (III) cercariae. Jejunal, ileal and renal sections were analyzed by direct immunofluorescence technique, aiming the detection of gamma globulins and complement C3. Intestinal sections were also stained by hematoxylin-eosin, during some periods of disease. The cellular composition of the jejunal and ileal granulomas seemed very similar, with many eosinophils and an increased number of mononuclear cells later on. The histological evaluation of these sections showed that the ileum may hold greater number of eggs, possibly being more affected than the jejunum. The results also suggest a mixed mechanism to the formation of intestinal granulomas, both cell and antibody mediated.
