Brief Summary

Critically ill patients experience major insults that lead to increased protein catabolism. Hypermetabolism occurs early and rapidly during the first week of critical illness to provide amino acids for the production of energy via gluconeogenesis, and also for the synthesis of acute phase proteins and repair of tissue damage. During acute phase, neuroendocrine and inflammatory responses promote protein breakdown and amino acid release. Under stress conditions, protein synthesis cannot match the increased rate of muscle proteolysis because of a state of anabolism resistance, which limits uptake of amino acids into muscles. Hypermetabolism results in a significant loss of lean body mass with an impact on weaning from the ventilator and muscle recovery. Functional disability may be long term sometimes with no full return to normal.

In critically ill patients, severe and persistent testosterone deficiency is very common and is observed early after ICU admission. This acquired hypogonadism promotes the persistent loss of skeletal muscle protein and is related to poor outcome.

Administration of testosterone induces skeletal muscle fiber hypertrophy, decreases protein breakdown in healthy young men and burned patients. It has been repeatedly shown that testosterone treatment enhances muscle mass and strength in young and older hypogonadal men and women and can improve physical performance.

Detailed Description

Type of trial

TestICUs-1 is a single center open-label parallel randomized controlled study phase II assessing the efficacy of testosterone gel to correct low testosterone serum levels associated with ICU acquired hypogonadism in mechanically ventilated patients with shock. TestICUs-1 will be conducted in the 10-bed medical ICU of the university hospital of Clermont-Ferrand. Study drug is Androgel® 1.62 mg/L approved by the ANSM for the treatment of hypogonadism in men containing 1.62% of testosterone.

Category of research Research involving human subjects aimed at assessing the efficacy of and safety to drug.

Study phase

* II/ Feasibility

* Technology Readiness Level : 7 B

A study assessing the efficacy of a multimodal strategy including treatment with testosterone gel, (75 mg/day in men and 25 mg/day in women) in improving physical activity in hemodialysis patients is in progress (Americano PHRC N 2012, AE Heng).
