Cholinergic Status and the Metabolic Syndrome (Choliner stat)

April 8, 2011 updated by: Tel-Aviv Sourasky Medical Center
The investigators aims in the current study are to examine whether the cholinergic status should be considered as another risk factor for the metabolic syndrome and it's co-morbidities and to test the effect of a hypocaloric high complex carbohydrates diet on the cholinergic status of overweight and obese adults with and without the metabolic syndrome.

Study Overview

Detailed Description

Intervention studies have demonstrated that the autonomic disturbances of the metabolic syndrome may be reversible. A reduction in body weight induced by a hypocaloric diet exerts a marked reduction in sympathetic activity in obese people with or without metabolic syndrome. Incorporation of regular, moderate intensity aerobic exercise training during a dietary weight loss program does not confer additional benefits on resting sympathetic neural activity, compared with weight loss by diet alone. A new method has been developed to examine the sympathetic-parasympathetic status of an individual - the cholinergic status. Cholinergic Status represents the total soluble circulation capacity for acetylcholine hydrolysis. Higher cholinergic status means the individual is more sympathetic .

A cross sectional study that took place in Tel Aviv Sorasky medical center and included 632 participants found that the cholinergic status is related to metabolic syndrome parameters in a dose response manner and that it correlates significantly with glucose,HbA1c, lipid profile and hs-CRP.

diet groups that meet every week for eight weeks or more.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
total soluble circulation capacity for acetylcholine hydrolysis
Time Frame: 8 weeks or more
8 weeks or more

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Inflammatory markers
Time Frame: 8 weeks or more
hs-CRP, ESR, Fibrinogen, IL-1b, IL-6, TNF-α
8 weeks or more
ROTEM - rotation thromboelastometry
Time Frame: 8 weeks or more
ROTEM documents the interaction of platelets with the coagulation factors from initial platelet-fibrin interaction, through platelet aggregation, clot strengthening and fibrin cross-linking to eventual clot lysis. Within 30 min, a ROTEM tracing provides information on clotting factor activity, platelet function and any clinically significant fibrinolysis.
8 weeks or more
Metabolic markers
Time Frame: 8 weeks or more
Fasting Glucose, HbA1c,Insulin, lipid profile
8 weeks or more
