PURPOSE OF REVIEW: Physical urticaria/angioedema syndromes (PUAs) are commonly encountered. They are identified by a history of physical factors provoking cutaneous symptoms, and confirmed by provocation testing. Recent guidelines have recommended use of challenge procedures for diagnosis; however, their positive/negative likelihood ratios have not been established. RECENT FINDINGS: We conducted a systematic review to determine the diagnostic utility of recommended office procedures for three common PUAs: dermatographia (DERMATO), cholinergic urticaria (CHOL), and delayed pressure urticaria/angioedema (DPUA)...

For many years, sweat has been recognized as an exacerbation factor in all age groups of atopic dermatitis (AD) and a trigger of cholinergic urticaria (CholU). Recently, we reported the improvement of AD symptoms by spray with tannic acid, which suppresses basophil histamine release by semipurified sweat antigens in vitro, and showering that removes antigens in sweat from the skin surface. We finally identified MGL_1304 secreted by Malassezia globosa as a major histamine-releasing antigen in human sweat. MGL_1304 is detected as a 17-kDa protein in sweat and exhibits almost the highest histamine-release ability from basophils of patients with AD and CholU among antigens derived from Malassezia species...

Cholinergic urticaria (CholU) is characterized by pinpoint-sized, highly pruritic wheals occurring upon sweating. Both direct and indirect theories in the interaction of acetylcholine (ACh) with mast cells have been put forward in the sweating-associated histamine release from mast cells. In the mechanism of indirect involvement of ACh, patients are hypersensitive to sweat antigen(s) and develop wheals in response to sweat substances leaking from the syringeal ducts to the dermis, possibly by obstruction of the ducts...

Acquired idiopathic generalized anhidrosis (AIGA) is a sweating disorder characterized by inadequate sweating in response to heat stimuli such as high temperature, humidity, and physical exercise. Patients exhibit widespread nonsegmental hypohidrosis/anhidrosis without any apparent cause, but the palms, soles, and axillae are rarely affected. Heat stroke readily develops due to increased body temperature. AIGA commonly affects young males. Approximately 30-60% of patients show complications of cholinergic urticaria, also known as idiopathic pure sudomotor failure or hypohidrotic cholinergic urticaria...

BACKGROUND: Cholinergic urticaria (CholU) is a frequent chronic urticaria disorder with itchy weal and flare-type skin reactions in response to physical exercise or passive warming. A higher frequency of atopy among CholU patients has been reported, but the significance of this observation is unclear. OBJECTIVE: To assess the prevalence and relevance of atopy in CholU patients. MATERIALS AND METHODS: Thirty CholU patients were assessed for atopic skin diathesis (atopic predisposition) by use of the Erlangen Atopy Score and divided into atopic and non-atopic predisposed CholU individuals...

BACKGROUND: Cholinergic urticaria (ChU) is characterized by small wheals induced by an elevated core temperature. Its pathomechanism and various aspects of its clinical manifestations are still poorly understood. This study aimed to evaluate the spectrum of symptoms and signs of ChU in Korean patients. METHODS: We retrospectively reviewed the medical records of patients diagnosed with ChU. RESULTS: Among 203 patients (188 male and 15 female), 29 (14%) complained only of an itching or burning sensation without visible skin eruption...

These recommendations for the definition, diagnosis and management of chronic inducible urticaria (CIndU) extend, revise and update our previous consensus report on physical urticarias and cholinergic urticaria (Allergy, 2009). The aim of these recommendations is to improve the diagnosis and management of patients with CIndU. Our recommendations acknowledge the latest changes in our understanding of CIndU, and the available therapeutic options, as well as the development of novel diagnostic tools.

Heat urticaria (HU) is a rare type of physical inducible urticaria, characterized by itchy erythema and well-demarcated weals appearing soon after heat exposure. Most cases occur in female patients aged 20-45 years. Both localized and generalized forms exist, depending on the limitation of the reaction to the skin area directly exposed to the physical stimulus or the involvement of distant sites, respectively. In most cases, HU is an immediate reaction, but delayed forms (mostly familial) have been described...

There have been recent advances in the classification and management of chronic urticaria. The new term chronic spontaneous urticaria (CSU) has replaced chronic idiopathic urticaria and chronic autoimmune urticaria. In addition, chronic inducible urticaria (CINDU) has replaced physical urticaria and includes other forms of inducible urticaria, such as cholinergic and aquagenic urticaria. Furthermore, novel research has resulted in a new understanding with guidelines being revised in the past year by both the American Academy of Allergy, Asthma, and Immunology (AAAAI) and the European Academy of Allergy and Clinical Immunology (EAACI)/Global Allergy and Asthma European Network (GA (2)LEN)/European Dermatology Forum (EDF)/World Allergy Organization (WAO)...

BACKGROUND: Cholinergic urticaria is a form of physical urticaria triggered by high ambient temperature, strenuous physical activity, and strong emotion. These same triggers may cause multisystem reactions that can be life-threatening. A study of patients with cholinergic urticaria with anaphylaxis was undertaken to describe the demographic and clinical features of this form of anaphylaxis. OBJECTIVE: To describe a cohort of patients with anaphylaxis triggered by high ambient temperature, exertion, and stress...

MGL_1304, a major allergen in human sweat for patients with atopic dermatitis and/or cholinergic urticaria, is secreted from Malassezia globosa on human skin. The amounts of MGL_1304 and IgE against MGL_1304 are evaluated by the histamine release test using basophils or mast cells sensitized with serum containing IgE against MGL_1304, and enzyme linked sorbent assay (ELISA) using MGL_1304 and anti-MGL_1304 antibodies. Here, we identified a human monoclonal IgE (ABS-IgE) that binds to the high affinity IgE receptor (FcεRI) and MGL_1304 with high affinity (KD = 1...

BACKGROUND: Hypohidrosis/anhidrosis are congenital or acquired sweating impairments. Among them, acquired idiopathic generalized anhidrosis/hypohidrosis (AIGA) is the most common, and characterized by favourable response to systemic corticosteroid, however, no clinical markers for disease severity or activity have been developed. OBJECTIVE: Our aim was to verify the usefulness of serum carcinoembryonic antigen (CEA) level monitoring as a clinical marker for disease activity of AIGA...

BACKGROUND: We previously identified MGL_1304 secreted by Malassezia globosa as a sweat antigen for patients with atopic dermatitis (AD) and cholinergic urticaria (ChU). However, purifying native MGL_1304 from human sweat or culture supernatant of M. globosa (sup-MGL_1304) is costly and time-consuming. Moreover, recombinant MGL_1304 expressed by using Escherichia coli (TF-rMGL_1304) needs a large chaperon protein and lacks the original glycosylation of yeasts. Thus, we generated a recombinant MGL_1304 by Pichia pastoris (P-rMGL_1304) and investigated its characteristic features...

Cholinergic urticaria (CU) is triggered by a rise in body temperature and can be complicated by bronchial hyperresponsiveness and anaphylaxis. It primarily affects young adults who actively engage in strenuous exercise, such as servicemen and servicewomen. If the patient reports a history of wheezing or difficulty breathing with urticaria, a water challenge test in a warm bath can be performed to confirm the presence of anaphylaxis. The test should be conducted in an environment in which the patient's airway can be secured and epinephrine can be administered if necessary...

Adrenergic urticaria (AU) is a rare type of stress-induced physical urticaria characterized by widespread pruritic urticarial papules. Diagnosis can be made by i.d. injection of adrenaline or noradrenaline, which produces the characteristic rash. Although the lesions of AU typically respond to beta-blockers such as propranolol, the therapeutic options for AU are limited. Here, we report a case of AU that was resistant to beta-blockers and successfully treated with clotiazepam. The clinical picture of AU resembles that of cholinergic urticaria (CU), however, positive noradrenaline test and negative acetylcholine skin test were useful for the differential diagnosis of AU and CU...
