Prevalence of gastric precancerous lesions in Ardabil, a high incidence province for gastric adenocarcinoma in the northwest of Iran.
BACKGROUND/AIMS: Ardabil Province, in northwestern Iran, has the highest rate of gastric (predominantly cardia) adenocarcinoma in Iran. This study aimed to investigate the feasibility of endoscopic screening and to look for associated Helicobacter pylori infection and gastric precancerous lesions. METHODS: One thousand one hundred and five adult volunteers, residents of Ardabil and Meshkinshahr, districts, 40 years old and above were selected and invited by a simple random household canvass in rural and urban locations. Informed consents were obtained and upper gastrointestinal video endoscopy was performed to biopsy all visible lesions and standard sites in the antrum, corpus, and cardia. RESULTS: One thousand and eleven of the invited individuals agreed to participate, including 494 men and 517 women, with a mean (SD) age of 53.32 (10.39) years. Endoscopy was well tolerated by all subjects; 96.7% of antral and 80.7% of cardia mucosal biopsies were satisfactory. The urease test or histology for H pylori was positive in at least 89.2% of subjects. Histological evidence of mucosal atrophy was seen in 39.3% of antral and 21.9% of cardia samples. Chronic gastritis with or without activity, reactive atypia of glandular epithelium, intestinal metaplasia, dysplasia, and cancer were found in 95.1%, 38.0%, 8.7%, 0.2%, and 0.3% of antral and 85.3%, 22.9%, 3.8%, 0.3%, and 0.1% of cardiac biopsies, respectively. CONCLUSION: Endoscopic screening for upper gastrointestinal diseases was feasible and well tolerated in Ardabil, Iran. Most subjects showed H pylori infection. Atrophic gastritis, reactive atypia, and intestinal metaplasia were common in antrum, corpus, and cardia subsites.

Tuberculous peritonitis in an endemic area.
BACKGROUND: Tuberculous peritonitis is a fatal disease if not diagnosed in time. AIMS: To identify the clinical, laboratory, and diagnostic features of tuberculous peritonitis in Iranian patients. PATIENTS: Included in the study were all cases of tuberculous peritonitis with a definite diagnosis confirmed by pathology in four referral University Hospitals in Tehran between 1989 and 1999. METHODS: All clinical, laboratory, and radiological findings as well as invasive procedures were reviewed. RESULTS: A total of 50 patients (30 female, 20 male), mean age 33.5 years were studied. Main presenting symptoms included abdominal pain (84%), weight loss (72%) and fever (50%). In 24% of patients a positive tuberculin test was found. Erythrocyte sedimentation rate >50 mm/h was detected in 60% of patients and 4.4% had an Erythrocyte sedimentation rate >100 mm/h. Laparoscopy or laparotomy showed peritoneal seeding in 74% of patients. CONCLUSIONS: Exudative ascites should give rise to clinical suspicion of tuberculous peritonitis in endemic areas or in immigrants from endemic areas. Laparoscopy is the most sensitive and specific diagnostic method.

Endoscopic findings in end-stage renal disease.
BACKGROUND AND STUDY AIMS: Patients with end-stage renal disease (ESRD) may demonstrate a number of gastrointestinal lesions and suffer subsequent complications. Our aim was to investigate the endoscopic findings in these patients and identify the predisposing factors. PATIENTS AND METHODS: During a 1-year period (February 2000 to January 2001), we studied consecutive patients with end-stage renal disease who were undergoing routine endoscopy before renal transplantation. The rapid urease test was also performed to detect Helicobacter pylori infection. Demographic and clinical data were collected. Logistic regression analysis was used to determine the risk factors for important endoscopic lesions, including esophagitis, gastroduodenal erosions, and peptic ulcers. RESULTS: We studied 206 patients (124 male, 82 female, mean age 38.9). Of the patients 73.8% were asymptomatic but some patients experienced nausea (12.6%), heartburn (8.7%), and abdominal pain (7.3%). Endoscopy was normal in 74 patients (35.9%). Abnormal endoscopic findings were duodenal erosions (32.0%), antral erosions (22.8%), diffuse antral erythema (27.8%), duodenal ulcer (7.3%), esophagitis (5.8%), angiodysplasia (4.4%), nodular duodenum (2%), and inflammatory gastric polyps (1.5%). The rapid urease test was positive in 58.8% of patients. Important endoscopic lesions were more common in men and in H. pylori-infected patients. Age, duration of dialysis, cause of the ESRD, presence of any symptoms, and hemoglobin levels were not found to be related to these lesions. Most patients with peptic ulcers were asymptomatic. CONCLUSIONS: Duodenal erosions (32.0%), gastric erosions (22.8%), diffuse antral erythema (27.8%) and duodenal ulcer (7.3%) are common lesions in patients with end-stage renal disease. Male gender and H. pylori infection are associated with a higher risk of these lesions. As there is no association between patients' symptoms and gastroduodenal lesions, which may increase the risk of post-transplant complications, the development of diagnostic strategies for the detection of these lesions is recommended.

Endoscopic esophageal cancer survey in the western part of the Caspian Littoral.
After a hiatus of 30 years an attempt is now being made to re-assess the previously reported very high esophageal cancer incidence rates in the Caspian Littoral. The extraordinarily high incidence rates found in the eastern side of the Littoral, were re-confirmed five years ago for the Turkoman region, using esophageal balloon cytology supplemented by esophagoscopy of suspected cases. The focus this time was on the Ardabil province in the western side of the Caspian Littoral, where the rates reported 30 years ago were moderately high. A pilot chromoendoscopic screening program was scheduled for 650 asymptomatic adults from a randomly selected part of the city of Ardabil and adjoining villages, to evaluate the overall patterns of esophageal disease and to establish the utility of endoscopy as an esophageal cancer screening tool. 504 healthy volunteers, giving a compliance rate of 77.5%, submitted to esophagogastroscopy without any mishaps. Contrary to expectation, no dysplasia or esophageal cancer was found in 914 satisfactory biopsy specimens. Total absence of esophageal cancer or precursor dysplastic changes in the surveyed population in the western part of the Caspian Littoral was at variance with the cancer registry findings of three decades ago for the western part of the Littoral. A plausible explanation could be the improved socio-economic conditions and life style changes which have taken place in the recent past all along the Caspian Littoral, except in the Turkoman Plain.

Second-line Helicobacter pylori eradication with a furazolidone-based regimen in patients who have failed a metronidazole-based regimen.
BACKGROUND/AIM: In developing countries the standard quadruple therapy containing metronidazole results in suboptimal eradication rates of Helicobacter pylori (<75%). In a retrospective study, we undertook to evaluate efficacy and tolerability of a furazolidone-based regimen (omeprazole, furazolidone, bismuth, and tetracycline) in patients who had previously failed the standard metronidazole-based regimen (omeprazole, metronidazole, bismuth, and amoxicillin). METHODS: The records of H. pylori infected patients who were referred to outpatient clinic (from March 1999 to August 1999) and who underwent previous eradication regimens were studied. A total of 320 cases were noted to have received a metronidazole-based quadruple regimen. From these 320 patients, 80 were noted to have failed this regimen based on a urea breath test. These 80 patients were enrolled in the study and given the furazolidone-based regimen. Side effects were assessed at follow-up visits. At least 2 months after the end of each therapy regimen, a (14)C-urea test was performed in each subject to document the cure of the patients. RESULTS: A total of 80 patients (39 males and 41 females) with a mean age of 43.8 +/- (SD) 13.3 years were studied. The H. pylori eradication rate was 90% with the furazolidone-based regimen. The side effects of this regimen were minor. CONCLUSIONS: A furazolidone-based regimen is effective in patients who do not achieve cure of H. pylori infection with the metronidazole-based quadruple therapy. In areas where the metronidazole resistance is high, initial therapy with a furazolidone-based regimen is recommended.
