About

This study investigates whether blockade of TNF will result in reduced inflammatory indices in patients with the metabolic syndrome

Full description

Metabolic syndrome is an increasingly prevalent disorder associated with elevated risks of type II DM (diabetes mellitus) and cardiovascular morbidity and mortality. A subclinical inflammatory state is thought to contribute to the pathophysiology of metabolic syndrome, insulin resistance, and coronary artery disease (CAD). TNF-alpha is an inflammatory cytokine that is increased in a spectrum of inflammatory diseases as well as in insulin resistance. TNF-alpha antagonists are clinically effective in the inflammation of arthritides, but have not been examined in the metabolic syndrome population. Moreover, data suggests that adiponectin, a recently discovered adipocytokine that may protect against the development of insulin resistance and atherosclerosis, may be downregulated by TNF-alpha. We propose a study in which we administer etanercept, a TNF-alpha receptor fusion protein, to subjects with metabolic syndrome to examine its effect on inflammatory markers,CRP, adiponectin and insulin resistance. This would be the first study to investigate the anti-inflammatory properties and insulin sensitizing potential of TNF-alpha blockade on the growing population with metabolic syndrome.

Inclusion criteria

Inclusion Criteria based on a modified WHO definition of metabolic syndrome

  1. Hyperinsulinemia in the upper quartile of the non-diabetic population defined as >= 10 mU/mL (Framingham Data, oral communication,James Meigs, MD) or fasting glucose 110-126 mg/dL

    Plus two of the following:

  2. Abdominal obesity defined by waist hip ratio > 0.90 for men and > 0.85 for women or BMI > 30 kg/m2

  3. Dyslipidemia including serum triglycerides ³ 150 mg/dl or serum HDL < 0.9 mmol/L for men (35 mg/dL) and < 1.0 mmol/L (39mg/dL) for women
