chronic urticaria (cu) also known as chronic idiopathic urticaria results in a lowered quality of life (qol). disease specific questionnaires are necessary to assess qol in cu patients. chronic urticaria quality of life questionnaire (cu-q2ol) is the only available and validated disease specific questionnaire in the assessment of qol in cu patients originally developed in italian language. the ...

Chronic spontaneous urticaria (CSU), defined as the occurrence of spontaneous wheals for more than six weeks, has been associated with autoimmune diseases. Herein, we report the unusual association of CSU, Graves' disease, and premature ovarian failure. Human leukocyte antigen (HLA) studies were performed. A 36-year-old woman presented symptoms and signs of hyperthyroidism for three months. In ...

BACKGROUND Chronic spontaneous urticaria (CU) is a common skin disorder, with an estimated prevalence of 0.5-1.8% in most populations. Around 30-50% of CU patients have an autoimmune etiology, with autoantibodies (autoAbs) against IgE, FcεRIα, and FcεRII/CD23. Although the in vivo autologous serum skin test (ASST) and in vitro histamine release/activation assay are the most frequently used scre...

Objective: To determine the prevalence of H. pylori infection in patients with idiopathic chronic urticaria (ICU) and to see if eradication of the bacterium affects the course of the urticaria. Patients and Methods: One hundred patients with idiopathic chronic urticaria and 43 healthy subjects (matched for age and sex) underwent serological testing for H. pylori infection. All patients with idi...

BACKGROUND The basophil activation test (BAT) using CD63 expression is a sensitive and specific tool for the diagnostic workup of autoimmune chronic spontaneous urticaria (CSU). The definition of a positive BAT is directly dependent on the reference range and the cutoff values established in control populations. As of now, the pediatric reference range and cutoff values of the CD63 BAT remain t...

BACKGROUND Chronic idiopathic urticaria (CIU) is a complicated skin disease with unknown pathophysiology. MicroRNAs (miRNA) have been shown to be active in cellular regulation. The goal of this pilot study was to examine whether miRNAs may be involved in the regulation of CIU or as biomarkers for CIU. METHODS Four groups of three patients each were selected: patients with either active hives ...

Methotrexate has immunosuppressive effects and is administered for refractory chronic urticaria. We present a case of Pneumocystis jirovecii pneumonia in a patient with refractory chronic urticaria managed by low-dose weekly methotrexate treatment (total cumulative dose 195mg). Our study highlights the importance of providing prompt diagnosis and treatment of Pneumocystis jirovecii pneumonia in...

BACKGROUND Thyroid autoimmunity has been increasingly reported to be associated with chronic urticaria (CU), and the possible clinical benefit of thyroid hormone or anti-thyroid drugs in some CU patients with autoimmune thyroid disease has been studied. However, the effect of thyroid hormone or anti-thyroid drugs on clinical symptoms of CU remains unclear. OBJECTIVE We investigated the clinic...
