Metabolic syndrome, a constellation of glucose intolerance, hypertension, dyslipidemia, obesity, pro-inflammatory and prothrombotic state culminating to development of premature cardiovascular diseases is a serious public health problem with significant impact on life expectancy, societal productivity and quality of life of those afflicted with it. Insulin resistance has been proposed as the key linking factor for the metabolic syndrome. Although the underlying mechanism for the development of insulin resistance, diabetes and metabolic syndrome is not fully understood, increasing evidence suggests that neurohormonal dysregulation plays a pivotal role in causing this growing health hazard. In our previous study of 307 middle-aged men, low insulin-like growth factor (IGF)-1 level was independently associated with insulin resistance and metabolic syndrome, especially amongst those with positive family history of diabetes. Replacement with growth hormone has been shown by other researchers to reduce body fat and improve metabolic profiles in patients with adult growth hormone deficiency and type 2 diabetes.
We hypothesize that treatment with growth hormone can lead to reduction of body fat, insulin resistance and cardiovascular risk factors in men with metabolic syndrome. This will be a 12-month prospective, randomized, double-blind, placebo-controlled study using growth hormone treatment in middle-aged men with metabolic syndrome. The primary outcome measure will be body fat distribution, including changes in visceral and mesenteric fat, whereas secondary outcome measure will be insulin sensitivity, and tertiary outcome will be variable parameters of metabolic syndrome.
The results of this study will have important impact on the treatment of patients with metabolic syndrome, and our understanding of the role of growth hormone in the pathogenesis of insulin resistance, diabetes and metabolic syndrome.
