About this study

Official title: The Effects of Vitamin B-6 and Glutathione on Inflammatory Responses, Homocysteine Metabolism, Oxidative Stress and Antioxidant Capacities in Patients With Liver Cirrhosis or Hepatocellular Carcinoma

This study is designed as a hospital-based cross-sectional and randomized placebo-controlled intervention trial. One hundred and fifty patients with either cirrhosis or cirrhosis combined with hepatocellular carcinoma (HCC) who meet the inclusion criteria will be recruited from Taichung General Veterans Hospital. One hundred patients will be randomly assigned to either the 1) placebo group (n = 25); 2) vitamin B-6 group; (50 mg/d, n = 25); 3) glutathione (GSH) group (500 mg/d, n = 25); or 4) vitamin B-6 (50 mg/d) plus GSH (500 mg/d) group (n = 25) for 3 mo. Data on demography, anthropometry and medical history will be collected. Patients with cirrhosis or cirrhosis combined with HCC will have fasting blood drawn in the clinics. Additionally, patients who participated in the intervention study will have blood drawn at month 0, 1, 2 and 3 during intervention period. Hematological measurements, plasma vitamin B-6 status, GSH, inflammatory markers, homocysteine, cysteine, SAM, SAH, oxidative stress indicator, oxidized GSH and GSH related antioxidant enzyme activities will be analyzed.

Read the detailed description

Liver cirrhosis is now the ninth leading cause of death and hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality among men and women in Taiwan. Vitamin B-6 and glutathione (GSH) are metabolized in liver, the role of vitamin B-6 and GSH playing in the inflammatory responses and antioxidant function would be impaired during hepatic injury. The purpose of this study is going to assess the effects of individual or combined supplementation of vitamin B-6 and GSH on homocysteine, cysteine, the ratio of S-adenosylmethionine (SAM)/S-adenosylhomocysteine (SAH), oxidative stress, oxidized glutathione (GSSG) and GSH related antioxidant enzyme activities in patients with cirrhosis and cirrhosis combined with HCC.

This study is designed as a hospital-based cross-sectional and randomized placebo-controlled intervention trial. One hundred and fifty patients with either cirrhosis or cirrhosis combined with HCC who meet the inclusion criteria will be recruited from Taichung General Veterans Hospital. One hundred patients will be randomly assigned to either the 1) placebo group (n = 25); 2) vitamin B-6 group; (50 mg/d, n = 25); 3) GSH group (500 mg/d, n = 25); or 4) vitamin B-6 (50 mg/d) plus GSH (500 mg/d) group (n = 25) for 3 mo. Data on demography, anthropometry and medical history will be collected. Patients with cirrhosis or cirrhosis combined with HCC will have fasting blood drawn in the clinics. Additionally, patients who participated in the intervention study will have blood drawn at month 0, 1, 2 and 3 during intervention period. Hematological, plasma vitamin B-6 status, GSH, inflammatory markers, homocysteine, cysteine, SAM, SAH, oxidative stress indicator, GSSG and GSH related antioxidant enzyme activities will be measured.

Hopefully, the results of this study could provide more pictures on the beneficial effects of vitamin B-6 and GSH supplementation on inflammatory responses, homocysteine, cysteine, the ratio of SAM/SAH, oxidative stress, GSSG and GSH related antioxidant enzyme activities in patients with cirrhosis and HCC.

Questions about this trial

What is this clinical trial studying?

A study testing vitamin B-6, Glutathione and Dextrins in people with Liver Cirrhosis and Liver Cancer, run by Taichung Veterans General Hospital at 1 site in Taiwan.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 22 Dec 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Yi-Chia Huang, PhD (+886-4-24730022 ext. 12198, ych@csmu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Oxidative stress marker (MDA concentation) (time frame: 3 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Dec 2014.
