About this trial

This is an interventional treatment trial for Abdominal Obesity focused on measuring growth hormone, obesity, abdominal obesity

Eligibility Criteria

40 Years - 65 Years (Adult, Older Adult)MaleDoes not accept healthy volunteers

Inclusion Criteria:

  • Fasting plasma glucose level ≥ 6.1 and ≤ 7.8 mmol/L (IFG) and/or a plasma glucose 2 hours after a 75g oral glucose load between 6.9-11.0 mmol/L (IGT).
  • BMI > 25 kg/m2.
  • Waist/hip ratio > 0.95

Exclusion Criteria:

  • Proliferative diabetic retinopathy.
  • Macro-albuminuri and/or serum creatinine >150mmol/L
  • Known ischemic heart disease, previous stroke or claudicatio intermittence.
  • Known malignancy.
  • Other hormonal therapy.

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Recombinant human growth hormone

Placebo

Arm Description

The subjects will receive treatment with recombinant human GH (Genotropin®) or placebo administered by a daily s.c. injection before bedtime. The initial dose of GH will be 0.4 IU per day increased to 0.8 IU after 2 weeks and to 1.2 IU after 4 weeks of treatment. Thus, the target dose is 1.2 IU per day which resembles approximately 0.015 IU/kg/day. The GH dose will be reduced by half in the event of side-effects

Outcomes

Primary Outcome Measures

Glucose tolerance

Secondary Outcome Measures

Fasting plasma glucose, serum insulin, HbA1c
Sleep architecture
Visceral adipose tissue
Progress of atherosclerosis (IMT)

5. Study Description

Brief Summary
The overall aim of this study is to investigate the effects of GH treatment in men with the Metabolic Syndrome and a high risk of developing type 2 DM. Forty men with abdominal obesity and impaired glucose tolerance will be randomized to two parallel treatment groups with GH and placebo for 12 months. The subjects will receive treatment with recombinant human GH (Genotropin®) or placebo administered by a daily s.c. injection before bedtime. The initial dose of GH will be 0.4 IU per day increased to 0.8 IU after 2 weeks and to 1.2 IU after 4 weeks of treatment. Thus, the target dose is 1.2 IU per day which resembles approximately 0.015 IU/kg/day. The GH dose will be reduced by half in the event of side-effects. Oral and written instructions in terms of administration and dosage will be given. The treatment can be discontinued by the patient. The treatment should be discontinued if malignancy is discovered, DM developes, if the subject experience a cerebrovascular disease and in the event of any other side-effects that is considered as serious. The treatment code for each subject included in the trial will be kept at the Sahlgrenska University Hospital Pharmacy. This code can be broken on the request of the investigator. Compliance will be assessed by collecting empty vials from the study subjects. The treatment is discontinued at the end of the study.
