Brief Summary

Patients with comorbidities have an increased risk of ulcer re-bleeding, especially within the 14 days after first bleeding event. Three-day high dose esomeprazole infusion can prevent peptic ulcer rebleeding after endoscopic therapy. However, the optimal dose of oral esomeprazole is uncertain, especially for high risky patients. This study is to test whether a double dose of oral esomprazole could reduce peptic ulcer rebleeding for patients with Rockall score ≥ 6. Additionally, the second aim of this prospective study was to identify the selection criteria to predict poor fading and residual major stigmata of recent hemorrhage (SRH) or early recurrent bleeding after successful endoscopic hemostasis and high-dose PPI infusion.

Detailed Description

Peptic ulcer bleeding is a common and lethal disease, and the recurrent bleeding is an independent risk factor leading to the mortality. The recurrent bleeding of peptic ulcers is related to the presence of the stigmata of recent hemorrhage (SRH). The fading time of SRH is around 3 to 6 days, therefore, the recurrent bleeding develops within 2-3 days after first bleeding episode. The aim of acute treatment of peptic ulcer bleeding is to reduce recurrent bleeding by using anti-secretory drugs. Accordingly, the common duration of omeprazole infusion is applied as 3 days after the endoscopic therapy. Moreover, recurrent bleeding is also positively linked with the presence of co-morbidities. In general, patients with underlying medical co-morbidities have increased rates of recurrent bleeding and longer duration in risk of recurrent bleeding than those without co-morbidity.

Nonetheless, even with continuous infusion of omeprazole for 3 days, recurrent bleeding rates remain high in certain patients such as those with the presence of underlying medical co-morbidities. Moreover, the duration of peptic ulcer recurrent bleeding is elongated up to the 14th day after the first bleeding episode in patients with co-morbidities. To prevent recurrent bleeding in such high risk patients, we showed therapeutic benefit for the prolonged course of 7-day low-dose intravenous omeprazole, which exerts better recurrent bleeding control than just 3-day high-dose infusion.

The intragastric 24-h median pH is 4.9 in patients with oral 40 mg omeprazole once daily, which is significantly higher than baseline pH in healthy subjects. However, gastric acid secretion is not suppressed completely during 24 hours with oral omeprazole 40 mg once daily. Several studies have shown that oral high-dose PPI is equally effective in raising the intragastric pH more than 6 and reducing recurrent bleeding as the intravenous route.

Hence, this study aims to test whether a higher dose of oral esomeprazole, which is more effective in maintaining favorable intragastric pH, could effectively reduce ulcer rebleeding in patients with comorbidities. This data will show the originality and clinical importance of a higher dose of oral esomeprazole for such high-risk patients with comorbidities with peptic ulcer bleeding.

Additionally, endoscopic treatment plus a 3-day intravenous proton pump inhibitor infusion is the standard protocol for treatment of peptic ulcer bleeding. Moreover, several studies have shown that PPI treatment prior to endoscopy could decrease the presentation of SRH and the need of endoscopic hemostasis. However, there are insufficient data to validate the efficacy of such standard treatment to fade the SRH. Therefore, several studies looked at the efficacy of routine second-look endoscopy, defined as scheduled repeat endoscopy after primary endoscopic hemostasis in patients at high risk of rebleeding. However, the role of second-look endoscopy and the selection criteria for patients who require second-look endoscopy remain uncertain. There is a pressing need to elucidate the role of second-look endoscopy in patients with peptic ulcer bleeding after high-dose PPI infusion.

Hence, the second aim of this prospective study is to identify the selection criteria to predict poor fading and residual major SRH or early recurrent bleeding after successful endoscopic hemostasis and high-dose PPI infusion. This data will show the originality and clinical importance to identify the risk factors to predict poor fading of SRH after current standard treatment and the patients who are indicated to receive second-look endoscopy.

Study Groups

Double oral dose

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole (Nexium®, AstraZeneca AB, Södertälje, Sweden) immediately after hemostasis was achieved spontaneously or by gastroscopy. Patients then received a 3-day continuous high dose (8 mg per hour) of esomeprazole infusion. Then, patients receive 40 mg oral esomeprazole twice daily for 11 days and followed by 40 mg once daily for 14 days.

esomeprazole (Nexium®, AstraZeneca AB, Södertälje, Sweden)

Intervention Type: DRUG

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole (Nexium®, AstraZeneca AB, Södertälje, Sweden) immediately after hemostasis was achieved spontaneously or by gastroscopy. Patients then received a 3-day continuous high dose (8 mg per hour) of esomeprazole infusion. Then, patients with Rockall score >=6 are randomized into the double oral dose group and the regular oral dose group. Patients with Rockall score <6 are assigned to the control group.

In the double oral dose group, patients receive 40 mg oral esomeprazole twice daily for 11 days and followed by 40 mg once daily for 14 days. In the other two groups, patients receive 40 mg oral esomeprazole 40 mg once daily for 25 days.

Regular oral dose

Each enrolled patient receives an 80 mg loading dose of intravenous esomeprazole (Nexium®, AstraZeneca AB, Södertälje, Sweden) immediately after hemostasis was achieved spontaneously or by gastroscopy. Patients then received a 3-day continuous high dose (8 mg per hour) of esomeprazole infusion. Then, patients receive 40 mg oral esomeprazole once daily for 25 days.
