About this trial

This is an interventional prevention trial for Psoriasis focused on measuring psoriasis, endothelial glycocalyx, arterial stiffness, coronary microcirculation, left ventricular myocardial deformation

Eligibility Criteria

18 Years - 75 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Caucasian patients with psoriatic disease (plaque-type psoriasis or psoriatic arthritis)
  • Body mass index ≥18.5 Kg/m2
  • If female, patients must be non-pregnant and non-breastfeeding

Exclusion Criteria:

  • History of acute coronary syndrome. Coronary artery disease will be excluded by a clinical history, examination and electrocardiogram.
  • Moderate or severe valve disease
  • Primary cardiomyopathies
  • Chronic obstructive pulmonary disease
  • Asthma
  • Chronic kidney disease
  • Liver failure
  • Malignancies

Thirty patients with psoriatic disease will randomized to receive 4 capsules a day of the placebo for 4 months

Outcomes

Primary Outcome Measures

Endocalyx effects on endothelial glycocalyx thickness
Endocalyx effects on endothelial glycocalyx thickness as assessed by perfused boundary region (PBR, micrometers) of the sublingual arterial microvessels using Sidestream Dark Field (SDF) imaging.

Secondary Outcome Measures

Endocalyx effects on arterial stiffness
Endocalyx effects on arterial stiffness as assessed by carotid to femoral pulse wave velocity (PWV, m/s) using tonometry.
Endocalyx effects on coronary microcirculation
Endocalyx effects on coronary function as assessed by measuring coronary flow reserve of left anterior descending artery. Coronary flow reserve is estimated by Doppler echocardiography as the ratio of coronary flow velocity after bolus intravenous adenosine infusion to coronary flow velocity at rest.
Endocalyx effects on left ventricular myocardial function
Endocalyx effects on left ventricular function as assessed by global longitudinal strain using speckle-tracking echocardiography.

5. Study Description

Brief Summary
The food supplement Endocalyx is considered to support the endothelial glycocalyx integrity by supplying sulfated polysaccharides, anti-oxidant enzymes and additional substrates for glycocalyx synthesis. The investigators will study the effect of Endocalyx on endothelial, vascular and left ventricular myocardial function in patients with psoriatic disease.
Detailed Description
Sixty patients with psoriatic disease, who are referred to the outpatient psoriasis clinic of the Attikon University Hospital, will be randomized to receive food supplement Endocalyx (4 capsules per day) (n=30) or placebo (n=30) for 4 consecutive months.
