BACKGROUND: Measurement of disease activity guides treatment of chronic spontaneous urticaria (CSU). A weekly Urticaria Activity Score-here, the average of twice-daily patient assessment of itch and hives scores summed over 1 week (UAS7TD )-measures severity from 0 to 42. Insufficient evidence exists whether disease activity states, defined by categorical UAS7TD scores, correlate with other patient-reported outcomes and treatment response. OBJECTIVE: To evaluate and compare categorical UAS7TD scores with selected measures of disease-related quality of life and impact...

BACKGROUND: Treatment with second-generation antihistamines is recommended in patients with chronic spontaneous urticaria (CSU). Some patients remain unresponsive even after up-dosing up to fourfold. Many third line treatment options have limited availability and/or give rise to significant side effects. We investigated effectiveness and safety of antihistamine treatment with dosages up to fourfold and higher. METHODS: This retrospective analysis of patients' records was performed in adult CSU patients suffering wheals and/or angioedema (AE)...

Hereditary angioedema (HAE) is a rare genetic disorder characterised by episodes of swelling without urticaria. Berinert® (CSL Behring) is a plasma-derived human C1 inhibitor (C1-INH) concentrate, approved for the treatment of HAE with C1-INH deficiency (C1-INH-HAE), however, it is often used off-label in Europe to treat HAE with normal C1-INH. OBJECTIVES: To report the clinical characteristics of patients with HAE with normal C1-INH (with F12 gene mutation; FXII-HAE) or of unknown origin (U-HAE), and their response to Berinert®...

Sreepurna Malakar
Bioactive food chemicals are substances present in food that are capable of interacting with living cells causing changes in physiological functions. Salicylic acid (SA), a plant hormone involved in plant immune response, is one such bioactive food chemical. Aspirin, a commercially available SA, might play beneficial roles in cardiovascular health and colon cancer. It may also cause urticaria, angioedema, asthma, and gastrointestinal symptoms in SA-sensitive individuals. Dietary SA might exert similar beneficial effects and/or may induce similar symptoms in hypersensitive individuals...

BACKGROUND: Non-steroidal anti-inflammatory drugs (NSAIDs) are the most frequent triggers of drug hypersensitivity with NSAIDs-induced urticaria/angioedema (NIUA) the most common phenotype. Loss of hypersensitivity has been reported for IgE-mediated reactions; however it has not been assessed in non-immunological reactions such as NIUA. We evaluated NSAID-hypersensitivity over time in NIUA patients. METHODS: Patients confirmed as NIUA by positive drug provocation test (DPT) with acetylsalicylic acid (ASA) during 2005-2012 (V1) were included (n=38)...

Omalizumab is very effective in the majority of patients with severe chronic spontaneous urticaria (CSU), but its mechanism of action is still unclear. In CSU the coagulation cascade is activated with an intensity that parallels the disease severity, and elevated plasma D-dimer levels are associated with a poor response to both antihistamines and cyclosporin. We measured D-dimer plasma levels before and after the first administration of omalizumab in 32 patients with severe CSU. A number of clinical and laboratory parameters were recorded, including the urticaria activity score, presence of angioedema, disease duration, C-reactive protein, anti-nuclear, and anti-thyroid antibodies...

BACKGROUND AND OBJECTIVES: Individuals who develop drug hypersensitivity reactions (DHRs) to chemically unrelated nonsteroidal anti-inflammatory drugs (NSAIDs) are considered cross-hypersensitive. The hallmark for this classification is that the patient presents a reaction after intake of or challenge with acetylsalicylic acid (ASA). Whether patients react to 2 or more NSAIDs while tolerating ASA remains to be studied (selective reactions, SRs). Objective: To identify patients with SRs to 2 or more NSAIDs including strong COX-1 inhibitors...
