UNASSIGNED: Chronic pruritus severely impacts the quality of life (QoL) of patients. Due to its multifactorial nature, the presence of factors that can predict itch-specific QoL needs comprehensive exploration.
UNASSIGNED: To determine the sociodemographic and itch-related factors that predict itch-specific QoL among patients suffering from chronic pruritus.
UNASSIGNED: We conducted a cross-sectional study on a cohort of patients with chronic pruritus at our itch clinic in Miami, Florida from 2016 to 2022 and explored predictors of itch-specific QoL using simple and multivariable linear regression models.
UNASSIGNED: Sociodemographic factors that had a negative impact on itch-specific QoL included female sex and multiracial ethnicity. The main itch-related factors that were associated with a negative impact on itch-specific QoL included pruritus in the upper extremity and buttocks/genital regions and associated factors such as pain, cold sensation, sweating, and stress.
UNASSIGNED: Single-center study at a tertiary care center with a primarily non-Hispanic White population and use of self-administered questionnaires.
UNASSIGNED: A variety of factors help predict the itch-specific QoL in patients with chronic pruritus. Understanding these factors can help clinicians evaluate and treat patients suffering from chronic itch.

UNASSIGNED: IgE bound on the surface of mast cells contributes to the pathogenesis of chronic spontaneous urticaria (CSU). Atopy is a predisposing factor for CSU, where omalizumab is a widely used monoclonal antibody to control urticaria symptoms via capturing serum free IgE. However, the role of serum free IgE is not clarified in CSU. The present study evaluated the clinical relevance of serum free IgE in patients with CSU.
UNASSIGNED: Eighty-eight patients with CSU and 76 healthy controls (HCs) were enrolled in this study. Serum total and Dermatophagoides pteronyssinus (Der p)-specific IgE levels were measured by ImmunoCAPs. The serum free IgE levels were measured by ELISA using a novel IgETRAP, and their associations with clinical parameters, including urticaria activity score (UAS), were evaluated. Changes in serum free and total IgE levels after omalizumab treatment were observed in 23 CSU patients in comparison between responders (≥50% reduction in UAS) and non-responders (<50% reduction).
UNASSIGNED: Significantly higher serum free/total IgE levels were noted in CSU patients than in HCs with a positive correlation between the 2 values (rho = 0.87, P < 0.001). Among CSU patients, atopics had significantly higher serum free IgE levels than non-atopics, while no associations were noted with UAS, urticaria duration, or the results of serum ANA or autologous serum skin tests. In addition, there were no significant changes in serum free IgE levels during 12 months of omalizumab treatment. No significant differences were noted in serum free/total IgE levels or clinical parameters between responders and non-responders, while responders have higher serum Der p-specific IgE level and its ratio to serum free/total IgE level than non-responders (P < 0.05, respectively).
UNASSIGNED: These findings suggest that increased serum free IgE may be involved in the development of CSU by activating mast cells, especially in atopics. High Der p-specific IgE level and its ratio to serum free IgE level may be a potential biomarker for predicting favorable responses to omalizumab in CSU.

UNASSIGNED: 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 H1-antihistamines (H1-AH) refractory chronic urticaria (CU) patients is limited.
UNASSIGNED: 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.
UNASSIGNED: In total, 159 patients from 24 study centres in Italy completed the study. At baseline, 221 (89.5%) and 8 (3.2%) patients had chronic spontaneous urticaria (CSU) and chronic inducible urticaria (CIndU), respectively, while 18 (7.3%) patients had concomitant CSU and CIndU. For CSU patients, mean dermatology life quality index and CU quality of life questionnaire scores reduced to 3.0 ± 4.9 and 14.6 ± 18.6 at Month 24 from baseline scores of 7.5 ± 6.6 and 33.2 ± 19.5, respectively, indicating an improvement in QoL. This was reflected in their work-life as work productivity impairment reduced considerably after 2 years. Only 71.9% CSU patients had a prior treatment, while during the study, 96.8% of the patients were treated with a medication. At baseline, only 52.9% CSU patients reported nonsedating H1-antihistamines as first-line of treatment in prior medication, this increased to 89.6% during current medication.
UNASSIGNED: This study shows that CSU has a considerable socio-economic burden and an improvement in QoL can be achieved in CSU patients if an appropriate therapeutic path is followed.

UNASSIGNED: Chronic urticaria (CU) is characterized by itchy recurrent wheals, angioedema, or both for 6 weeks or longer. CU can greatly impact patients\' physical and emotional quality of life. Patients with chronic conditions are increasingly seeking information from information and communications technologies (ICTs) to manage their health. The objective of this study was to assess the frequency of usage and preference of ICTs from the perspective of patients with CU.
UNASSIGNED: In this cross-sectional study, 1800 patients were recruited from primary healthcare centers, university hospitals or specialized clinics that form part of the UCARE (Urticaria Centers of Reference and Excellence) network throughout 16 countries. Patients were >12 years old and had physician-diagnosed chronic spontaneous urticaria (CSU) or chronic inducible urticaria (CIndU). Patients completed a 23-item questionnaire containing questions about ICT usage, including the type, frequency, preference, and quality, answers to which were recorded in a standardized database at each center. For analysis, ICTs were categorized into 3 groups as follows: one-to-one: SMS, WhatsApp, Skype, and email; one-to-many: YouTube, web browsers, and blogs or forums; many-to-many: Instagram, Twitter, Facebook, and LinkedIn.
UNASSIGNED: Overall, 99.6% of CU patients had access to ICT platforms and 96.7% had internet access. Daily, 85.4% patients used one-to-one ICT platforms most often, followed by one-to-many ICTs (75.5%) and many-to-many ICTs (59.2%). The daily ICT usage was highest for web browsers (72.7%) and WhatsApp (70.0%). The general usage of ICT platforms increased in patients with higher levels of education. One-to-many was the preferred ICT category for obtaining general health information (78.3%) and for CU-related information (75.4%). A web browser (77.6%) was by far the most commonly used ICT to obtain general health information, followed by YouTube (25.8%) and Facebook (16.3%). Similarly, for CU-specific information, 3 out of 4 patients (74.6%) used a web browser, 20.9% used YouTube, and 13.6% used Facebook. One in 5 (21.6%) patients did not use any form of ICT for obtaining information on CU. The quality of the information obtained from one-to-many ICTs was rated much more often as very interesting and of good quality for general health information (53.5%) and CU-related information (51.5%) as compared to the other categories.
UNASSIGNED: Usage of ICTs for health and CU-specific information is extremely high in all countries analyzed, with web browsers being the preferred ICT platform.

UNASSIGNED: A Worldwide Antihistamine-Refractory Chronic Urticaria (CU) patient Evaluation (AWARE) is a non-interventional, multicenter study including patients from Europe, Central and Latin America, Asia-Pacific, and the Middle East. AWARE describes real-world evidence for CU, including clinical characteristics, treatment patterns and the impact on quality of life.
UNASSIGNED: Over the 2-year study, therapy changes, angioedema occurrence, and patient-reported outcomes (PROs) were recorded over 9 visits, including dermatology life quality index (DLQI) and 7-day urticaria activity score (UAS7). Data were stratified into subgroups: chronic spontaneous urticaria (CSU), chronic inducible urticaria (CIndU), or CSU + CIndU.
UNASSIGNED: Out of 4838 patients analyzed, 9.9% were receiving no treatment for their CU symptoms at baseline, and 20.4% were receiving first-line non-sedating H1-antihistamine at approved doses. The predominant baseline therapy was up-dosed non-sedating H1-antihistamines (25.5%). By Visit 2, omalizumab was the overall most commonly used therapy (29.6%), increasing to 30.1% by the end of the study. Baseline DLQI scores for patients with CSU, CIndU and CSU + CIndU were 8.3, 7.6 and 9.1, respectively; scores decreased over the study for CSU and CSU + CIndU patients, but fluctuated for CIndU patients. Baseline angioedema occurrence was higher in CSU and CSU + CIndU patients, reported in 45.4% and 45.5% of patients, respectively, compared to 17.0% in CIndU patients. By the final visit, angioedema had decreased to 11.9% and 11.2% for CSU and CSU + CIndU, respectively, and 9.6% for CIndU.
UNASSIGNED: CU patients are undertreated at baseline; after entering the AWARE study, more patients received appropriate treatment. However, over two thirds are not escalated to third-line treatments.
