[The gastroduodenal mucosa in patients with portal hypertension: correlation with blood gastrin].

PURPOSE: gastroduodenal mucosa of two groups of patients with chronic liver disease was studied: schistosomotic mansoni patients (SH) and non-schistosomic patients (NSH). Results were compared to serum-gastrin levels. TYPE: prospective study. PLACE: Unicamp University Hospital (Hospital das Clínicas), Campinas, São Paulo, Brazil. PATIENTS: 24 patients were included in the results, out of 26 patients studied. Two groups of study: 12 patients with schistosomiasis and liver fibrosis (SH), and 12 patients with liver cirrhosis (NSH) secondary to alcoholism or to hepatitis. PROCEDURES: esophagogastroduodenoscopies and biopsies of gastric antrum and duodenum. Function tests of the liver were also studied. RESULTS: results of gastrinemia were found within normal ranges in both groups. Student test ("t") did not show differences between groups at the 5% level. However, patients with chronic liver cirrhosis had more significant and severe endoscopic findings and chronic inflammatory processes of the gastroduodenal mucosa (acute gastritis, duodenitis and ulcers) than patients with liver fibrosis. CONCLUSIONS: patients with liver cirrhosis due to high risk of gastroduodenal bleeding should be maintained under continuous vigilance, appropriate diet and mucosa cytoprotectors. Furthermore, more research is required to study the etiology of gastroduodenal lesions in these specific groups of patients.

Intestinal lymphangiectasia in systemic lupus erythematosus.

The case of a woman with SLE and protein-losing enteropathy secondary to intestinal lymphangiectasia is described. Corticosteroid therapy improved all clinical symptoms, laboratorial findings and intestinal histological alterations.

[Intrahepatic cholangiodysplasia in 2 brothers. Concept of the entity].

The histopathologic aspects of the intrahepatic dysplasic bile ducts (cholangiodysplasia) found in two brothers, one of them asymptomatic, are discussed. This entity is characterized by interlobular bile ducts proliferation and portal fibrosis, without cholestasis but with chronic active cholangitis. The differential diagnosis and the probable genesis of the cholangiodysplasias are discussed.

[Incidence and epidemiology of Barrett's epithelium at the Gastrocentro-UNICAMP].

It is very important in the clinical practice to identify the individuals with Barrett's esophagus, because they are at risk to develop adenocarcinoma in the columnar epithelium. The objective of this research is to verify the incidence of this specific kind of epithelium at the "Gastrocentro", at State University of Campinas-UNICAMP, Campinas, SP, Brazil, among the total of 15,976 upper digestive endoscopies, performed from january of 1992 to December of 1995. From the total examinations performed were identified 2,381 patients (14.9%) presenting reflux esophagitis (grades I-IV, Savary-Miller). Among this group of patients, the endoscopist suspected of Barrett's esophagus in 110 cases (4.6%) and biopsed the distal esophagus. However, only in 85 cases (77.3%) the pathologist confirmed the diagnosis of Barrett's epithelium. The patients with Barrett's esophagus were 53 males (62.3%), presenting the mean age of 52.2 years and the following grades of esophagitis: grade I-33 cases (38.8%); grade II-15 cases (17.7%); grade III-15 cases (17.7%), grade IV-12 cases (14.1%) and without esophagitis-10 cases (11.7%). The incidence of Barrett's esophagus among the patients with reflux esophagitis was 3.57%, and among the total of examinations performed at the "Gastrocentro" during the period of four years was 0.53%, totalizing 22,4 cases/100,000 habitants.
