Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
No interventions are being tested. One-off investigation of each participant's HGH levels will be conducted by a baseline blood sample and repeated blood samples at 15 minute intervals over 75 minutes after a single injection of arginine (500mg/Kg up to a maximum dose of 30000mg) and human growth hormone releasing hormone (1microgram/Kg up to a maximum dose of 100 micrograms).

Single group
Other design features
Phase
Not Applicable
Type of endpoint/s
Safety/efficacy
Statistical methods / analysis
Testing the rate of human growth hormone (HGH) deficiency in the stroke survivor population. Currently the population rate of HGH deficiency should be near zero. This is a hypothesis-generating pilot study as there were no previous data from stroke patients on which to base a sample-size calculation.
