ABSTRACT
AIM: The aim of this study was to provide practical recommendations for optimizing the use of conventional and biological systemic treatments for moderate-severe chronic plaque psoriasis, particularly in case of transitioning and switching. METHODS: A total number of 147 dermatologists from 33 different countries including Italy achieved consensus in providing practical recommendations for the use of conventional and biological treatments for moderate to severe psoriasis based on systematic literature review and/or expert opinion. RESULTS: In general, the continuous treatment regimen should be preferred in order to achieve a complete and long-term control of psoriasis. However, the treatment could be stopped or the dose reduced in case of complete disease clearance. A conventional drug could be associated to biological treatment in selected cases. Transitioning and/or switching could be considered in case of inefficacy or intolerance. A period of wash up is required if transitioning or switching is due to safety issues. CONCLUSION: This study provides practical suggestions for the optimal use of conventional and biological treatments for chronic plaque psoriasis.
ABSTRACT
AIM: Fabry's disease is an X-linked recessive abnormality of glycosphingolipid metabolism. Increased levels of endothelial prothrombotic factors have recently been demonstrated in Fabry's disease, whereas endothelial function has not been studied using high resolution ultrasound. METHODS: We enrolled 6 patients (4 male, 2 female; mean age, 37 years) and 12 sex matched control subjects (mean age, 37 years). Patients' exclusion criteria included a prior history of cardiac disease, diabetes and treated or untreated hypertension. Patients underwent: anamnesis, physical examination, EKG, 2-dimensional echocardiography with tissue Doppler, measurement of body weight and height, blood pressure. Biochemistry variables were also considered: fasting blood sugar, total cholesterol, HDL-C, LDL-C, triglycerides, fibrinogen, C reactive protein and homocysteine. Using high resolution ultrasound, we assessed the brachial vasodilator response to reactive hyperemia (endothelium-dependent) and sublingual nitroglycerin (NTG) (endothelium-independent). Flow-mediated dilatation (FMD) was expressed as percentage change in post-stimulus diameter in comparison with the baseline. RESULTS: In baseline condition, there was no significant difference between patients and controls in the brachial artery diameter (3.5+/-0.55 vs 3.1+/-0.4). After reactive hyperemia, the FMD change was significantly higher in controls than in patients (16.5+/-6.3% vs 9.3+/-6.2%, P<0.05). After NTG, endothelium-independent vasodilation did not show a significant difference between cases and controls (15+/-7.7% vs 13.8+/-7.1%). CONCLUSIONS: Our study demonstrated the presence of endothelial dysfunction in patients with Fabry's disease in comparison to controls. We hypothesized that endothelial dysfunction may contribute to the pathogenesis of ischemic events in patients with Fabry's disease.
