Achtergrond van het onderzoek
Background:
treatment with phytosphingosine leads to improvement in cholesterol spectrum and insulin resistance in animal models
Objective:
• To examine if dietary Phytosphingosines improve insulin sensitivity in male patients with the metabolic syndrome.
• To examine if dietary Phytosphingosines improve blood cholesterol levels in male patients with metabolic syndrome.
• To examine the safety and possible side effects of dietary Phytosphingosines
Study Design:
Double blind randomized cross-over placebo controlled intervention study
Planned Sample:
10 patients
Drugs and Dosages:
Phytosphingosine, twice a day 0.5 grams for 28 days
Placebo, twice a day for 28 days
Main Parameters:
• Anthropometric: Weight, height, waist and hip circumference, BIA
• Glucose metabolism: HOMA-IR, HOMA-β
K-value by IVGTT
• Plasma concentrations: Total cholesterol (TC), HDL-C-cholesterol (HDL-C),
LDL-C-cholesterol (LDL-C), Triglycerides
Glucose, insulin
ASAT, ALAT, gamma-GT, LDH, alkaline phosphatase
