Three trearment schemes with colloidal bismuth subcitrate (Q-ULCER) in peptic ulcer with Helicobacter pylori

ABSTRACT

Background. Since the discovery, several decades ago, of the infection of the gastric mucosa with Helicobacter pylory and its association with chronic antral gastritis and peptic ulcer, the treatment of ulcer illness has recently been revolutionized. Methods. In this study, the clinical effectiveness of three patients suffering from gastroduodenal peptic ulcer with helicobacter pylori were distributed randomly into three groups. Group I (n = 17) received 240 mg (CBS every 12 h for 6 weeks. Group II (n = 17) received 240 mg CBS every 8 h for 10 days. Group III (n = 19) received 240 mg CBS every 12 h for 6 weeks, plus metronidazole 500 mg every 8 h plus amoxicillin 750 mg every 12 h for 10 days. A duodenoscopy investigation with antrum biopsy for a morphologic study and detection of the germ was carried out by means of urease test and histological study (Warthin-Sarry and hematoxylin-eosin). Results. The three schemes of treat schemes of treatment were effective for ulcerous healing with 70.5 percent, 82.3 percent, and 78.2 percent, respectively, without significant differences. The highest clearing index (52.6 percent) was obtained in group III. Conclusions. With these treatment, the Helicobacter pylori eradication was only observed in 47.3 percent of the patients studied
