Biomarkers and clinical characteristics of autoimmune chronic spontaneous urticaria: Results of the PURIST Study.

2019

Background: Autoimmune chronic spontaneous urticaria (aiCSU) is an important subtype of chronic spontaneous urticaria (CSU) in which functional IgG autoantibodies to IgE or its high-affinity receptor (FcεRI) induces mast cell degranulation and subsequent symptom development. However, it has not been tightly characterized. This study aimed to better define the clinical and immunological features and to explore potential biomarkers of aiCSU. Methods: This was a multinational, multicenter study of 182 CSU patients. The clinical features studied included: urticaria activity and impact (UAS7 and quality of life); autologous serum skin test (ASST); IgG anti-FcεRI and IgG anti-IgE; IgG-anti-thyrop…

Autologous whole blood injections to patients with chronic urticaria and a positive autologous serum skin test: a placebo-controlled trial.

2005

<i>Background:</i> Patients with chronic urticaria (CU) frequently exhibit positive skin test reactions to autologous serum (ASST). Therapies aimed at inducing tolerance to circulating histamine-releasing factors in ASST+ CU patients, e.g. by treatment with autologous whole blood (AWB), have not yet been tested. <i>Objective:</i> To test whether ASST+ CU patients can benefit from repeated low-dose intramuscular injections of AWB. <i>Methods:</i> We characterized CU severity and duration, anti-Fc<sub>Ε</sub>RI and anti-IgE expression, use of antihistamines, and quality of life in 56 CU patients (ASST+: 35, ASST–: 21) and assessed the t…

Chronic Spontaneous Urticaria in Patients with Common Variable Immunodeficiency

2018

Common variable immunodeficiency (CVID) is a predominantly antibody deficiency and is one of the most common primary immunodeficiencies in adulthood. Replacement therapy with Ig has significantly reduced infectious complications; however, malignant, autoimmune, and inflammatory diseases are still current major causes of morbidity and mortality. In recent years, interest has increased regarding allergic manifestations that may be associated with primary immunodeficiencies; however, no data are currently available on chronic spontaneous urticaria (CSU). In this report, the authors describe CSU in patients with CVID attending their centre. Three CVID patients were affected by CSU and were unre…
