title: Carotid intima-media thickness and serum leptin in psoriasis.
abstract: BACKGROUND
  Psoriasis, a chronic inflammatory immune disorder, has been linked to increased cardiovascular mortality and morbidity. Leptin, an obesity-related peptide, has been shown to exert direct effects on the vascular endothelium and on vascular smooth muscle cells. Carotid intima-media thickness (IMT) measurement is a promising tool for detecting atherosclerosis in its pre-occlusive/subclinical phase.
  
  
  OBJECTIVE
  The objective of the study was to evaluate carotid IMT and serum leptin levels in psoriatic patients as an indicator of subclinical atherosclerosis.
  
  
  METHODS
  The study was conducted in 50 psoriatic patients and 10 healthy controls. The clinical severity of skin affection in psoriatic patients was estimated using the psoriatic area and severity index (PASI). Serum leptin levels (ng\ml) and lipid profiles [including serum triglyceride (TG), serum low density lipoproteins (LDL) and serum high density lipoproteins (HDL)] were measured from blood samples. Carotid IMT was measured using carotid duplex ultrasonography.
  
  
  RESULTS
  Psoriatic patients showed significantly higher leptin levels and higher IMT than controls. The mean of the intima-media thickness of the four vessels examined (MIMT) showed a positive correlation with patients' mean ages, disease duration, body mass index, PASI scores, systolic blood pressure, diastolic blood pressure, leptin levels, LDL levels and triglyceride levels and no correlation with the mean HDL level.
  
  
  CONCLUSIONS
  Psoriasis is an independent risk factor for subclinical atherosclerosis. This cardiovascular impairment is influenced mainly by disease severity, serum TG levels and serum leptin levels.
