Differential Expression of Proteins Involved in Skin Barrier Maintenance and Vitamin D Metabolism in Atopic Dermatitis: A Cross-Sectional, Exploratory Study.

Atopic dermatitis (AD) is a chronic inflammatory skin disorder influenced by proteins involved in skin barrier maintenance and vitamin D metabolism. Using an intra-patient design, this study compared protein expression in intra-lesional (IL) and peri-lesional (PL) skin biopsies from AD patients and examined associations between protein levels, vitamin D status, and clinical features. Forty-four biopsies from twenty-two AD patients were analyzed using antibody microarrays targeting twelve proteins.

Association between Vitamin D Receptor Polymorphisms, Tight Junction Proteins and Clinical Features of Adult Patients with Atopic Dermatitis.

Introduction: Few studies have explored the intricate connections between vitamin D receptor (VDR) gene polymorphisms, VDR, tight junction (TJ) protein expression and clinical features of atopic dermatitis (AD).

Methods: From 43 adult AD patients, VDR polymorphisms were genotyped from peripheral blood samples using polymerase chain reaction-restriction fragment length polymorphism. VDR, occludin, claudin-1 and ZO-1 protein expression from skin lesion biopsies were assessed by immunohistochemistry.

The Fatty Acid and Protein Profiles of Circulating CD81-Positive Small Extracellular Vesicles Are Associated with Disease Stage in Melanoma Patients.

The early detection of cutaneous melanoma, a potentially lethal cancer with rising incidence, is fundamental to increasing survival and therapeutic adjustment. In stages II-IV especially, additional indications for adjuvant therapy purposes after resection and for treatment of metastatic patients are urgently needed. We investigated whether the fatty acid (FA) and protein compositions of small extracellular vesicles (sEV) derived from the plasma of stage 0-I, II and III-IV melanoma patients ( = 38) could reflect disease stage.

Socio-economic burden and resource utilisation in Italian patients with chronic urticaria: 2-year data from the AWARE study.

Introduction: In Italy, the real-world evidence on the extent of adherence to guidelines and the benefits of recommended therapeutic medications and their impact on the quality of life (QoL) of H-antihistamines (H-AH) refractory chronic urticaria (CU) patients is limited.

Methods: AWARE (A World-wide Antihistamine-Refractory chronic urticaria patient Evaluation) was a global prospective, non-interventional study of CU in real-world setting which included patients aged ≥18 years with a medically confirmed diagnosed of CU present for more than 2 months. In this study, the disease characteristics, pharmacological treatments and patient-reported outcomes (PROs) are reported.
