A multicenter, randomized, double-blind clinical trial examining the effect of oral human recombinant epidermal growth factor on the healing of duodenal ulcers.

Background: Our aim was to study the efficacy of oral human recombinant epidermal growth factor (EGF) in the treatment of duodenal ulcers, on the basis of its repairing actions in the gastrointestinal tract.

Methods: A placebo-controlled, multicenter, randomized, and double-blind study was conducted. Treatment groups were A) placebo solution, B) 10 microg/ml of human recombinant (hr)-EGF, and C) 50 microg/ml of hr-EGF, three times daily during 6 weeks.

Oral human recombinant epidermal growth factor in the treatment of patients with duodenal ulcer.

The epidermal growth factor has been shown to be mucoprotective and to accelerate healing of gastroduodenal ulcers in animals. A prospective, positively controlled clinical trial was conducted. Seventy five patients with duodenal ulcer were randomly distributed in three groups to receive oral human recombinant epidermal growth factor in 1% carboxymethyl cellulose at two different doses (450 mg or 600 mg/day), or cimetidine.

[Influence of colloidal bismuth subcitrate, metronidazole, and amoxycillin on Helicobacter pylori and gastroduodenal ulcer healing].

In many works performed in different countries, including Cuba, the microorganism Helicobacter pylori (Hp) is involved in the etiopathogenesis and relapse of gastroduodenal ulcer (GDU). In a previous work, we saw that under treatment of Colloidal bismuth subcitrate (CBS) or Metronidazole (M) alone during 4 weeks, the percentage of Hp clearance obtained was very low. So, we decided to extend the treatment with a unique drug up to 6 weeks or to make a combination of drugs during 4 weeks.

[Emergency fibroendoscopy. Basic exploration in the diagnosis of upper digestive bleeding (experience in 200 cases)].

Prognosis in upper gastrointestinal hemorrage (UGIH) depends mostly upon an early diagnosis. The addition of an around the clock endoscopist on duty in the hospital was decided upon to provide inmediate evaluation of all UGIH. The team performed 200 endoscopies, many within the first 12 hours and all of them before 24 hours of bleeding.

[Fibroesophagogastroduodenoscopy in the gastroenterology institute (experience in 8,000 cases)].

The results of 8,000 fiber-optic endoscopic procedures performed at the Gastrenterologic Institut during a 5 year period are analyzed in this paper. This extensive was possible not only because the method is simple and innocous due to the flexibility and high technology of these apparatue, but also because the Cuban Public Health System made feasible the exploration without expenses for all the patients needing it. Thirty-two percent of the explorations in an ever greater scale in the search for gastric cancer in its early stages.
