BACKGROUND: Cholinergic urticaria (CholU) is a common skin disease characterized by the development of pinpoint-sized weals and severe itch upon physical exercise. Little is known about the epidemiology of CholU. CholU can occur at any age and has the highest prevalence among young adults. As of now, it is unclear whether patients of different age show differences in the clinical manifestation of CholU, duration of disease, comorbidities or response to treatment. METHODS: Here, we analysed the demographic data and clinical characteristics including disease duration and comorbidities of 200 patients with CholU, 12-76 years of age...

BACKGROUND: Omalizumab, a recombinant anti-IgE antibody, effectively treats chronic spontaneous urticaria. Evidence is lacking in patients with chronic inducible urticarias (CIndUs), which are frequently H1-antihistamine resistant. OBJECTIVE: From the current published literature, we aimed to determine the strength of evidence for omalizumab efficacy and safety in the treatment of CIndUs. METHODS: We performed a PubMed search to identify evidence on omalizumab use in the following 9 CIndU subtypes: symptomatic dermographism, cold urticaria, delayed-pressure urticaria, solar urticaria, heat urticaria, vibratory angioedema, cholinergic urticaria, contact urticaria, and aquagenic urticaria...

Cholinergic urticaria occasionally occurs in combination with anaphylactic symptoms. However, this has not been widely reported. Herein, we report the case of a 14-year-old Japanese male who was diagnosed with cholinergic urticaria accompanied by anaphylaxis. The patient, who was suffering from atopic dermatitis and bronchial asthma, had developed wheals after exercising or bathing, which would have increased his core body temperature, since summer 2014. He experienced two episodes of severe systemic symptoms and wheal development when he took a bath after eating in December 2014 and the following January...

Sweat is an exacerbation factor in atopic dermatitis (AD) in all age groups. A body core temperature elevation with sweating triggers cholinergic urticaria (CholU). We recently reported that AD symptoms are improved by tannic acid-containing spray, which suppresses the basophil histamine release induced by semi-purified sweat antigen in vitro, and by showering, which removes antigens in sweat from the skin surface. Sweat contains small amount of proteins including proteases, protease inhibitors, and anti-microbial peptides...

Symptoms of acquired idiopathic generalized anhidrosis (AIGA) include heat retention and/or heat stroke due to the effects of the disorder on the perspiration ability of the whole body under thermal environmental changes or exercise. Additionally, cholinergic urticaria can also occur in these patients. AIGA has a major impact on everyday life. However, the effects of AIGA severity on the quality of life (QOL) of the patients have not been sufficiently defined. The objective of this study was to evaluate the correlation between AIGA severity and QOL...

Anhidrosis/hypohidrosis are conditions presenting various level of sweating dysfunction. Among them, acquired idiopathic generalized anhidrosis (AIGA) presents inadequate decrease or loss of sweating without apparent neurological and dermatological symptoms except cholinergic urticaria. Recently, serum level of carcinoembryonic antigen (CEA), one of the most well-known tumor markers, has been proposed as a clinical marker reflecting activity of AIGA. This study was performed to verify the specificity and independence of serum CEA level from the other serum tumor markers especially related to adenocarcinoma...

Cold urticaria and cholinergic urticaria are two distinct entities. The presentation of exclusive cold-induced cholinergic urticaria is very rare. The patient described herein had experienced urticaria in the exclusive setting of exercising in a cold environment. Urticarial testing including laboratory and in-office testing was all negative. The patient has prevented urticaria symptoms with oral antihistamine therapy. Pure cold-induced cholinergic urticaria is rarely described in literature. This form of urticaria has yet to be described in a pediatric patient...

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...

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...
