Treatment of reflux gastritis: double blind comparison between clebopride and domperidone. A preliminary report.

Altered gastro-duodenal motility seems to be a major factor of alkaline gastritis. Therefore prokinetic drugs have been extensively used for the treatment of this disease. Aim of this study has been to compare the effects of domperidone with those of a more recent drug of the orthopramide class, clebopride. Thirty patients affected by reflux gastritis have been randomly allocated to one of the two treatments. Clinical symptoms, endoscopic and histologic appearance of gastric mucosa, gastric pH and bile acid concentration in gastric juice have been evaluated before and after a four week course of therapy. A statistically significant improvement was observed for the clinical symptoms in the subjects treated with clebopride. Even if no statistical difference has been pointed out for the other parameters between and within the two groups, a slight trend in favour of clebopride was observed. It is concluded that clebopride is at least as effective as domperidone for the treatment of reflux gastritis but that more prolonged studies and different administration schedules are requested for a better evaluation.

Pancreatic function in chronic inflammatory bowel disease.

This study was prospectively carried out to evaluate the frequency and clinical significance of pancreatic impairment in the course of chronic inflammatory bowel disease (CIBD). Twenty-seven patients affected by ulcerative colitis or Crohn's disease were submitted to a secretin-cerulein test, oral glucose test (OGT) and to indirect immunofluorescence (IFL) for detection of autoantibodies against exocrine and endocrine tissue. A bicarbonate plus enzyme or only an enzyme insufficiency was found in 11/27 patients, whereas isolated lipase decrease was observed in 18 subjects. In the results of the OGT and the indirect IFL test there was no difference between patients and controls. These data demonstrate that pancreatic impairment is a far more frequent occurrence than generally recognized in clinical practice. The decrease of lipase secretion could worsen the consequences of malabsorption in Crohn's disease of the small intestine. Therefore we think that a pancreatic assessment is advisable, at least in Crohn's disease patients with steatorrhea.

Flow-cytometric assessment of DNA index and percent S phase cells in bronchogenic epidermoid carcinoma.

The DNA index and percent S phase cells were assessed in 45 bronchogenic epidermoid carcinomas from paraffin-embedded retrieved material by flow cytometry. Previously, a comparison between flow cytometric findings from fresh and from paraffin-embedded material was made. The DNA index and the percent S phase cells from fresh and paraffin-embedded material were strongly correlated. Only 3 of the 45 cases were diploid. The DNA index was significantly lower in grade 1 than in grade 2-3 tumors. No correlations were found between DNA index and presence of lymph node metastases, but the percent S phase cells was significantly higher in lymph-node-positive tumors.

Mycosis fungoides. Detection of OKT6+ cells by cytofluorographic analysis in one case.

An 86-year-old woman had a subjective history of pruritus and intermittent fever. The clinical diagnosis of mycosis fungoides was confirmed by cutaneous and lymph node biopsies. Immunohistochemical, cytofluorographic, and ultrastructural analysis was performed. According to immunohistochemical findings the lymphoid cells infiltrating the skin and lymph nodes were phenotypically T-helper cells. Cytofluorographic and ultrastructural analysis of the peripheral blood detected a small number of cerebriform lymphoid cells. By immunohistochemistry, these cells showed the same phenotype that was found in the skin and lymph nodes. OKT6+ cells, which are not usually present, were also found in the peripheral blood. These findings may suggest a functional relationship between the skin and the lymphoid system.

Frequency of pancreatographic changes in subjects with upper abdominal symptoms and its relationship with alcohol intake.

The aim of this study was to evaluate the endoscopic retrograde pancreatographic (ERP) findings in respect of alcohol intake. Two hundred eleven patients consecutively submitted to ERP for upper abdominal symptomatology, with suspected pancreatic disease (SPD; 79 patients) or without (NSPD; 132 subjects), were classified in 3 groups of different ethanol intake: 1 (0-40 g/day), 2 (41-80 g/day), 3 (more than 80 g/day). The following conclusions could be drawn: (1) the frequency of ERP changes increases with the increase of alcohol intake both in SPD (34.6-63.8%) and NSPD (8.2-29.8%); (2) the frequency of pancreatic cancer was not related to alcohol intake, but in NSPD it was about 2-fold that in SPD: 12/132 (9.1%) vs 4/79 (5.06%); (3) a pancreatic morphological assessment, by means of ERP or other imaging techniques, should be performed in every subject with upper abdominal pain of unknown origin both in alcoholics (for the high incidence of chronic pancreatitis) and in non-alcoholics (for the risk of pancreatic cancer, which approximates 10%).
