Branched-chain Aminoacids in Sleep Apnea Syndromes (ARSAS) (ARSAS)

This study has been withdrawn prior to enrollment.
Information provided by:
University Hospital, Limoges Identifier:
First received: April 30, 2010
Last updated: December 4, 2012
Last verified: April 2010

The initial hypothesis is that branched-chain aminoacids (BCAA) administration could be beneficial to patients suffering from sleep apnea syndrome (SAS), the aim of the present work is to verify this hypothesis.

The literature data demonstrate that a BCAA complementation improves the physical performances, protects lean mass and increases VO2 max during training.

We demonstrated earlier that this complementation can cure at less partly the hypoxemia of chronic obstructive pulmonary patients by a stimulation of respiratory centres.

Further study details as provided by University Hospital, Limoges:

Primary Outcome Measures:
  • The principal criterion of BCAA efficacy is based on the depth of arterial desaturation during sleep, assessed by the level of SaO2 during the validated sleep time measured during the polysomnography performed at the end of the study. [ Time Frame: 2 years ]

Secondary Outcome Measures:
  • The secondary criteria are apnea and snore counting, the intergroup difference between the beginning and the end of treatment on nocturnal desaturations. [ Time Frame: 2 years ]

Enrollment: 0

Arms Assigned Interventions
Active Comparator: Branched-chain aminoacids
Branched-chain aminoacids are natural constituents of the food. Branched-chain aminoacids will be orally administered in the form of capsules.
Drug: Branched-chain aminoacids

Branched-chain aminoacids will be orally administered in the form of capsules, at the rate of a capsule for physical 7 Kilograms weighty and a day. Every capsule containing 375 milligrams of branched-chain aminoacids.

The treatment will last 3 weeks.

Placebo Comparator: placebo
The placebo will be orally administered in the form of capsules
Drug: Placebo

Placebo will be orally administered in the form of capsules, at the rate of a capsule for physical 7 Kilograms weighty and a day.

The treatment will last 3 weeks.
