Background: Recent studies suggest that psoriasis may be a pathogenic factor for the metabolic syndrome and atherosclerosis. The aim of our study was to investigate the metabolic state in psoriatic patients in order to clarify the association between psoriasis and insulin resistance.Methods: This single-centre, case- control study was performed between 2008 and 2010 to evaluate the metabolic state of thirty chronic plaque type psoriatic patients in comparison with the control group. The criteria of insulin resistance (Body Mass Index (BMI), Systolic Blood Pressure, Fasting Plasma Glucose, Oral Glucose Tolerance Test (OGTT), Serum Insulin and Lipid Profile) were assessed for each participant.Results: Thirty psoriatic patients with a mean disease duration of 3.94 + 2.96 years and 30 healthy controls were recruited for the study. Only one patient in each group filled the criteria of insulin resistance, and there was no significant difference between the two groups. The mean Fasting Plasma Glucose (FPG), Triglyceride (TG) and Systolic Blood Pressure (SBP) levels were significantly higher in psoriasis patients as compared to the controls (p=0.044, p=0.014 and p=0.001, respectively). In contrast, no statistically significant differences were observed in mean BMI, OGTT, insulin and HDL levels between the two groups.Conclusion: Despite the absence of any significant association between insulin resistance and psoriasis, it could be concluded that psoriasis may be an independent risk factor for diseases such as Ischemic Heart Disease (IHD) and Diabetes Mellitus (DM), hypertension and obesity.

Background and aim: Acanthosis nigricans (AN) is characterized by hyperpigmented velvety plaques of body folds and neck. Insulin can have a role in the pathogenesis of this disease and hyperinsulinemia as a consequence of insulin resistance may stimulate the formation of the characteristic plaques of AN. In this study insulin resistance was compared in obese women with and without AN.Materials and Methods: Glucose tolerance test (GTT) and fasting blood insulin were measured in two groups of obese women (BMI>30 kg/m2) with AN (32 cases) and without AN (34 cases) and insulin resistance was determined using HOMA formula.Results: The mean fasting blood insulin in two groups with and without AN were 15.5±8.5 and 12.2±4.1 IU/mL; respectively (P<0.05). The mean of insulin resistance in two groups with and without AN were 3.5±1.9 and 2.6±0.9; respectively (P<0.05). The results of GTT showed that the mean fasting blood sugar was 89.5±12 mg/dl and following using glucose were 144±7 mg/dl after 30 minutes, 132±45 mg/dl after 60 minutes, 107±30 mg/dl after 120 minutes in persons with AN and in the other group were 87±8, 130±3, 122±26 and 100±26 mg/dl; respectively. The difference between two groups was only significant after 60 minutes.Conclusion: Acanthosis nigricans maybe a marker of insulin resistance in obese women.
