Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 30 to 70 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Over 520,000 healthy men and women aged 25-85 were enrolled between 1992 and 2000 across 23 EPIC centres in 10 European countries including Denmark, France, Germany, Greece, Italy, the Netherlands, Norway, Spain, Sweden, and the United Kingdom. This study used data from 2,974 control participants from four case-control studies on colorectal (n=491), hepatobiliary (n=327), kidney (n=635), and prostate cancer (n=1,521) nested in the EPIC cohort, for which targeted metabolomics data had been acquired.

Who may be able to join

  • Aged 30-70
  • Healthy volunteers residing within defined geographical areas (where study centers are located). Different settings by centre; mostly general population with some exceptions: women of a health insurance company for teachers and school workers (France), women attending breast cancer screening (Utrecht-The Netherlands, and Florence-Italy), mainly blood donors (most centers in Italy and Spain) and a cohort consisting predominantly of vegetarians (the 'health-conscious' group in Oxford, UK).

Who cannot join

  • Individuals without metabolomics data
  • Individuals without data on alcohol consumption at recruitment

About this study

Official title: Circulating Metabolites Associated With Alcohol Intake in the European Prospective Investigation Into Cancer and Nutrition Cohort

Alcohol consumption is a risk factor for numerous health conditions and an important cause of death. Identifying metabolites associated with alcohol consumption may provide insights into the metabolic pathways through which alcohol may affect human health. The objective of this study is to investigate associations of alcohol consumption with circulating concentrations of 123 metabolites including amino acids, acylcarnitines, hexoses, biogenic amines, phosphatidylcholines, and sphingomyelins. For this purpose, the investigators use data from the European Prospective Investigation into Cancer and Nutrition (EPIC) study and applied a discovery and replication approach.

Read the detailed description

This study used data from 2,974 control participants from four case-control studies on colorectal (n=491), hepatobiliary (n=327), kidney (n=635), and prostate cancer (n=1,521) nested in the EPIC cohort, for which targeted metabolomics data had been acquired. Alcohol consumption at recruitment was self-reported through dietary questionnaires. Metabolite concentrations were measured by tandem mass spectrometry using the BIOCRATES AbsoluteIDQTM p180 kit. Data were randomly divided into discovery (2/3) and replication (1/3) sets. Multivariable linear regression models were used to evaluate confounder-adjusted associations of ln-transformed alcohol consumption with Z-standardized ln-transformed residual metabolite concentrations. Metabolites significantly related to alcohol intake in the discovery set (FDR q-value<0.05) were further tested in the replication set (Bonferroni-corrected p-value<0.05). Of the 72 metabolites significantly related to alcohol intake in the discovery set, 34 metabolites were also significant in the replication analysis, including three acylcarnitines, the amino acid citrulline, four lysophosphatidylcholines, 13 diacylphosphatidylcholines, seven acyl-alkylphosphatidylcholines, and six sphingomyelins. Associations with acylcarnitines and phosphatidylcholines were generally positive, while mostly inverse associations were observed with citrulline and sphingomyelins.

This study adds novel knowledge regarding circulating metabolites associated with alcohol consumption, and provides leads for further studies into the underlying biological mechanisms. A better understanding of metabolic pathways affected by alcohol consumption may contribute to the development of mechanism-tailored intervention strategies to prevent and treat alcohol-related conditions. Furthermore, it may help to identify biomarkers of alcohol consumption facilitating early preventive strategies in individuals at-risk for developing alcohol-related morbidities.

Questions about this trial

What is this clinical trial studying?

An observational study of No Condition, Focus: Metabolites of Alcohol Consumption, run by International Agency for Research on Cancer.

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 2 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: finished, as of the sponsor's last update on 23 Jan 2018. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Circulating metabolite concentrations (time frame: Laboratory analyses performed between Oct 2012-Oct 2016). 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 23 Jan 2018.
