Summary

The study consists on determining whether melatonin decreases oxidative stress in Barrett's esophageal mucosa after 6 months of treatment. In order to achieve the clinical trial, the patients will be randomized to two possible arms: omeprazole alone or omeprazole plus melatonin. The patients will be followed around four visits during six months.

GERD is one of the most prevalent pathologies in the digestive tract. Barrett's esophagus, a complication of chronic GERD, has attracted the attention of researchers due to its condition of pre-neoplastic lesion. At present, treatment of Barrett's patients is limited to acid inhibition with PPIs. Although there are several studies which indicate that treatment with PPIs could decrease the incidence of high grade dysplasia and EAC, treatment with PPIs does not eliminate the risk of EAC in these patients. Therefore, it is necessary to find chemo-preventive agents that stop neoplastic progression of Barrett's esophagus. Among them, antioxidants have become the most promising agent. This pilot study will determine the efficacy of melatonin in the chemoprevention of EAC.

So, the main objective of this study is to determine whether melatonin decreases oxidative stress in Barrett's esophageal mucosa after 6 months of treatment.

To evaluate whether melatonin modifies other mechanisms associated to neoplastic progression in BE patients: proliferation and apoptotic index and molecular markers of progression: 17pLOH, 9pLOH, p16 methylation and DNA ploidy (tetraploidy and/or aneuploidy).

Conditions

  • Barrett's Esophagus

Interventions

DRUG

Omeprazole

Omeprazole 40 mg/day alone. Patients will take the capsule once in the morning before breakfast. This is the standard therapy for patients suffering from Barrett's esophagus.

DRUG

Melatonin

Omeprazole 40 mg/day + Circadin 6 mg/12 hours. Patients will take the Omeprazole capsule once in the morning before breakfast together with 3 tables of 2 mgs of Circadin (melatonin). In the evening, before dinner, patients will take 3 tablets of 2 mg of Circadin.
