Aims: Psoriasis is an immune-mediated dermatosis with cardio-metabolic comorbidities. The aim of this study was to assess insulin-resistance, lipid abnormalities, and cardiovascular risk biomarkers in psoriatic patients with or without type 2 diabetes mellitus (T2DM).Methods and materials: We enrolled 425 patients: 86 psoriatics, 69 psoriatics with T2DM, 120 T2DM patients, and 150 healthy subjects. We measured the Psoriasis Area and Severity Index (PASI), body mass index (BMI), insulin-resistance parameters [glycosylated hemoglobin (HbA1c), fasting plasma glucose (FPG), fasting plasma insulin (FPI), and with homeostasis model assessment index (HOMA index)], lipidic panel, plasminogen activator inhibitor-1 (PAI-1), homocysteine, soluble adhesion molecules, matrix metalloproteinase, and adipocytokines.Results: FPG, HbA1c, and HOMA-IR were higher in diabetics with psoriasis (p < 0.0001) than in psoriatics. FPI levels were higher in diabetics with psoriasis than in diabetics and psoriatics (p < 0.0001), and higher in psoriatics than controls (p < 0.0001). Psoriatics and diabetics with psoriasis showed higher triglyceride and LDL-C levels (p < 0.0001) than diabetics. Homocysteine was higher in psoriatics and diabetics with psoriasis (p < 0.0001) than in diabetics. PAI-1 was higher in diabetics with psoriasis than diabetics (p < 0.01). sICAM-1 and sVCAM-1 were higher in diabetics with psoriasis than diabetics (p < 0.001 and p < 0.01) and psoriatics (p < 0.001 and p < 0.0001). Visfatin and resistin were lower in psoriatics (p < 0.0001) and in diabetics with psoriasis (p < 0.001 and p < 0.0001, respectively) than diabetics.Conclusions: A limitation of this study is that there is a significant difference in mean age between controls and other study groups: the lack of matching between case and control groups may interfere with the external validity of the study findings. Despite this, the study highlights a pathogenetic link between psoriasis, considered a pre-diabetic condition, and diabetes. Insulin-resistance seems to be the keystone of psoriasis comorbidities. Psoriasis reinforces diabetes, causing a greater cardiometabolic risk.
Transient myeloproliferative disorder (TMD) is a spontaneously resolving clonal myeloid proliferation characterized by circulating megakaryoblasts in the peripheral blood that is restricted to neonates with Down syndrome (DS) or those with trisomy 21 mosaicism. Cutaneous manifestations of TMD are observed in only 5% of affected neonates and present as a diffuse eruption of erythematous, crusted papules, papulovesicles, and pustules, often with prominent and initial facial involvement. We describe the case of a male infant with DS and TMD, associated with a vesiculopustular eruption, which appeared on day 36 of life, and review previous cases.
Mycosis fungoides (MF) is a rare disease and is considered the most common form of cutaneous T-cell lymphoma. Given the infrequent incidence of MF in patients under the age of 20, there are no established guidelines for the treatment of these patients; the overwhelming majority have an early-stage disease and progression to more advanced stages is very rare. This study presents the safety and effectiveness of photo-photochemotherapy as a first-line approach in the treatment of an early-stage MF even in young patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
