Trial summary

This project aims to assess the impact of chronic micro-inflammation on age-related loss of muscle (sarcopenia) and bone (osteopenia). The hypothesis is that chronic micro-inflammation and oxidative stress, which prevalence increases during ageing, may participate in the pathogenesis of both sarcopenia and osteopenia.

About this study

Official title: Chronic Micro-inflammation and Bone and Muscular Status in Elderly

This project aims to assess the impact of chronic micro-inflammation on age-related loss of muscle (sarcopenia) and bone (osteopenia). The hypothesis is that chronic micro-inflammation and oxidative stress, which prevalence increases during ageing, may participate in the pathogenesis of both sarcopenia and osteopenia.

Read the detailed description

In order to explore the effect of a moderate chronic inflammation on skeletal muscle function and protein metabolism and on bone status, two groups of 16 subjects each will be selected according to their inflammatory status ie non-inflamed versus micro-inflamed. The volunteers will be sampled twice at week 0 and week 6 in order to quantify plasma concentration of C reactive protein (CRP) using the ultra sensitive assay. The subjects exhibiting CRP lower than 1 mg/l twice will be included in the non-inflamed group and the subjects exhibiting CRP higher than 3 and lower than 15 mg/l will be included in the micro-inflamed group.

During the two weeks before the metabolic studies dietary intakes, DEXA, muscle function, VO2 max and biomarkers of bone remodelling will be assessed. Volunteers will then be submitted to a diet controlled for its protein content, for 4 days (1 g protein/kg/day and 30 kcal/kg/day) before metabolic investigations. One day before, urine will be collected for metabolomics. On the day of metabolic investigations, after an overnight fast, blood samples will be collected for albumin, fibrinogen, inflammatory cytokine and adipokine determination. Then, the subjects will be perfused with L-[1-13C] leucine for 8 hours (post absorptive sate then post prandial satte) during which expired gas and blood samples will be taken, as well as 2 muscle biopsies. Isotopic enrichments in expired gas, in plasma cetoiscaproate and in free or protein-bound leucine in muscle will be measured to determine proteolysis and proteosynthesis rate of muscle proteins.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Measurement of muscle protein synthesis using stable isotopes and muscle biopsies.Other

    Measurement of muscle protein synthesis using stable isotopes and muscle biopsies.

    Isotopes are :

    (13C)bicarbonate (0.09 mg/kg fat-free mass) and L(1-13C)leucine (1.3 mg/kg fat-free mass) (intravenous way) L-(5,5,5 2H3) leucine(0.09 µmoles/(kg de fat-free mass.min) (oral way)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Isotopic enrichments in expired gas, in plasma cetoisocaproate and in free or protein-bound leucine in muscle will be measured to determine proteolysis and proteosynthesis rate of muscle proteins.

    Measured: at week 0 and week 6

Secondary outcomes (1)
  1. Splanchnic extraction of amino acids, bone metabolism, muscular strength, global metabolism and quality of life.

    Measured: at week 0 and week 6

Questions about this trial

What is this clinical trial studying?

A study testing Measurement of muscle protein synthesis using stable isotopes and muscle biopsies. in people with Age-related Degenerated Disease, run by University Hospital, Clermont-Ferrand at 1 site in France.

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 5 inclusion and 12 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 29 Sep 2010. 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 France. 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. 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 Patrick Lacarin (04.73.75.11.95, placarin@chu-clermontferrand.fr), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Isotopic enrichments in expired gas, in plasma cetoisocaproate and in free or protein-bound leucine in muscle will be measured to determine proteolysis and proteosynthesis rate of muscle proteins. (time frame: at week 0 and week 6). 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 29 Sep 2010.
