The involvement of the hemostatic system in immune-mediated inflammation is widely reported. Many coagulation factors play a role in the pathogenesis of autoimmune diseases, such as systemic vasculitis and systemic lupus erythematosus. Hemostatic disorders are also involved in asthma and chronic spontaneous urticaria (CSU). Factor XIIa (FXIIa) was one of the first coagulation factors implicated in inducing both humoral and cellular responses and is therefore considered a prime new therapeutic target in immune-mediated inflammation...

BACKGROUND: Chronic rhinosinusitis (CRS) is a common yet under-recognised chronic inflammatory disease of the nose and paranasal sinuses that is classified according to the presence (CRSwNP) or absence (CRSsNP) of nasal polyps. METHODS: This paper reports the methodology and descriptive results of the Global Allergy and Asthma European Network (GALEN) rhinosinusitis cohort. We established a large CRS cohort within the GALEN consortium (European FP6 research initiative) to identify inflammatory endotypes, the natural disease course, and its impact on health-related quality of life (HRQoL)...

IgE is the antibody isotype found at the lowest concentration in the circulation. However IgE can undeniably play an important role in mediating allergic reactions; best exemplified by the clinical benefits of anti-IgE monoclonal antibody (omalizumab) therapy for some allergic diseases. This review will describe our current understanding of the interactions between IgE and its main receptors FcεRI and CD23 (FcεRII). We will review the known and potential functions of IgE in health and disease: in particular, its detrimental roles in allergic diseases and chronic spontaneous urticaria, and its protective functions in host defense against parasites and venoms...

Topical sunscreens are the mainstay for protection from ultraviolet (UV) radiation. With skin cancer rates on the rise and great interest in reversing or preventing the effects of photoaging, new molecules with potential to defend against UV damage have received a great deal of attention. Specifically, there is a growing interest in herbal substances that offer protection against the damaging effects of UV rays. Herbal substances may work as adsorbents of the UV rays and antioxidants and potentially have few side effects...

Wheat is the most commonly grown cereal. Immunological reaction to wheat may be IgE or T-cell- mediated. Asthma could be induced by inhaled flour or by exposure to allergens present in bakery products. In patients with IgE-mediated allergy to wheat proteins there is no specific therapy, except oral immunotherapy (OIT). There are few data regarding OIT with wheat protein in allergic patients. We present a case of a 32-yearold female patient, who worked for 5 years in wheat and bakery products industry, who developed an occupational asthma and chronic urticaria after flour inhalation or ingestion of foods that containit...

OBJECTIVE: To characterize and analyze the inpatient and emergency pediatric dermatology consults in our academic hospital center. METHODS: We reviewed 485 consultations that were done by the University of Puerto Rico Department of Dermatology from July 2007 to June 2012. The date, patient age and gender, consulting service, presumptive diagnosis, final diagnosis, and diagnostic procedures performed were documented for each consult. RESULTS: The patients' ages ranged from newborn to 18 years; the 13 to 18 years age group was the most common (29%)...

Food-dependent exercise-induced anaphylaxis (FDEIAn) is an anaphylactic reaction induced by physical exercise after ingestion of certain meals. FDEIAn is not very frequent, but recent case reports associated with various meals indicate an upward trend. Here, we report the data of various food specific IgEs and the clinical course of an experience with a patient who exhibited a unique FDEIAn reaction. Various food specific IgEs including staple food were positive with high levels. We could not find out the cause food of FDEIAn...

Little attention has been given to the burden of chronic urticaria (CU) in Japan compared with other skin diseases, such as atopic dermatitis (AD) and psoriasis. The primary objective of the RELEASE study was to evaluate the real-life quality-of-life impairment in CU patients in Japan. Data were collected from 1443 urticaria, 1668 AD and 435 psoriatic patients; 552 urticaria patients who presented urticaria symptoms for over 6 weeks were defined as CU. The mean Dermatology Life Quality Index (DLQI) total score was 4...

Basophils are blood granulocytes and normally constitute less than 1% of blood peripheral leukocytes. Basophils share some morphological and functional similarities with mast cells, and basophils were once regarded as redundant and negligible circulating mast cells. However, recent studies reveal the indispensable roles of basophils in various diseases, including allergic and pruritic diseases. Basophils may be involved in itch through the mediation of a Th2 immune response, interaction with other cells in the skin, and secretion of a wide variety of itch-related mediators, e...

Chronic idiopathic urticaria (CIU), also known as chronic spontaneous urticaria, is characterized by the presence of hives on most days of the week, for 6 weeks or longer, and without an identifiable or consistent cause. Evaluation is clinical and based on the presence of episodic urticarial lesions. Although patients are subject to overtesting during the diagnosis of CIU, guidelines suggest starting with three basic laboratory tests. Treatment is a stepwise approach, involving second-generation antihistamines, histamine2 antagonists, leukotriene receptor antagonists, first-generation antihistamines, and potent antihistamines...

BACKGROUND: Chronic urticaria (CU) has an adverse effect on academic achievement and psychosocial development in children. OBJECTIVE: We aimed to investigate the natural course of CU and to identify relevant factors associated with a poor CU prognosis in Korean children. METHODS: We retrospectively analyzed 253 children with episodes of wheals or angioedema at least 3 times a week that persisted for at least 6 weeks. Clinical data and laboratory results were obtained from medical records and parental telephone interviews...

A wide variety of foods may cause or aggravate skin diseases such as contact dermatitis, contact urticaria, or atopic dermatitis (AD), both in occupational and private settings. The mechanism of action underlying allergic disease to food, food additives, and spices may be immunologic and non-immunologic. The classification and understanding of these reactions is a complex field, and knowledge of the possible reaction patterns and appropriate diagnostic test methods is essential. In addition, certain foods may cause worsening of atopic dermatitis lesions in children...

PURPOSE OF REVIEW: NSAIDs are the drugs most frequently involved in hypersensitivity reactions (HSR). These are frequently prescribed at all ages. HSR are of great concern and can affect people at any age. These drugs can induce reactions by stimulating the adaptive immune system (IgE or T cell), known as selective responders or more frequently by abnormalities in biochemical pathways related with prostaglandin metabolism. These are known as cross-intolerant. With some exceptions, skin testing and in-vitro studies are of little value in selective responders...

A wide differential diagnosis must be considered in a patient presenting with urticarial plaques. Although acute and chronic urticaria are the commonest diagnoses, other differential diagnoses include polymorphous eruption of pregnancy, mast cell disorders, hypereosinophilic syndrome, urticarial vasculitis, pemphigoid, systemic lupus erythematosus, and autoinflammatory disease. This review will specifically address urticarial vasculitis and autoinflammatory syndromes. These entities represent contrasting examples of urticarial-like lesions resulting from either an adaptive immune complex-mediated mechanism (urticarial vasculitis) or an innate immune-mediated mechanism (autoinflammatory disorders), with differing therapeutic implications...

This review summarises available information about adverse food reactions in dogs and cats. Much of the published information on the pathogenesis of adverse food reactions in these species is transferred from what is known in mice and human beings. Clinical signs affect mostly the integument and gastrointestinal system. Pruritus of the distal limbs, face, ears and ventrum is the most common cutaneous presentation in dogs, although urticaria has also been reported. In cats, all so-called 'cutaneous reaction patterns' may be due to adverse food reactions...

Ciprofloxacin, a very common antibiotic used in our day-to-day practice can cause adverse cutaneous reactions in 1-2% of patients. Photosensitivity, urticaria and maculopapular rash are the usual skin reactions. Fixed drug eruption (FDE) is an uncommon side effect of ciprofloxacin. Ciprofloxacin-induced generalised bullous FDEs have been very rarely reported in the literature. We report one such case of a young man who developed generalised non-bullous FDEs after treatment with ciprofloxacin.

Aims Itch often occurs in cutaneous conditions characterized by some degree of inflammation, e.g. atopic dermatitis, psoriasis or urticaria. It is unclear to which extent cutaneous inflammation causes sensitization of pruriceptive primary afferent C-fibers. The aim of this study was to explore if inflammation induced by UVB (B-ultraviolet rays) modify neurogenic inflammation and itch associated with experimental itch provocations. Methods Twenty healthy volunteers (10F/10M, 26.2 ± 1.6 years) were included...

Case series summary Cutaneous mastocytosis is a disorder rarely reported in veterinary dermatology and usually described as 'urticaria pigmentosa'. This study aimed to evaluate the diagnosis, treatment and outcome of 13 affected cats, selected from the files of a private referral dermatology practice within a period of 14 years. Breeds of the affected individuals included Sphynx (n = 9), Devon Rex (n = 2) and Sphynx/Devon Rex crossbreeds (n = 2). Females (n = 9) were over-represented and the median duration of clinical signs prior to diagnosis was 8 months...
