“…Our group previously reported the prevalence of CholU among chronic urticaria patients of 0.9% and 0.5% in the years 2007 and 2011, respectively [20,21]. The reported prevalence of CholU among general population in countries located in the tropical zones ranged from 0.023 to 11.2% [6][7][8]. Most studies including our study have shown the male predominance [6].…”

“…In severe patients, CholU may be related to exercise-induced anaphylaxis, a severe wheal-flare reaction with systemic involvement including difficult breathing, wheezing, or abdominal pain [5]. The reported prevalence of CholU in a general population varies from 0.023% to 11.2% in temperate zone countries [6][7][8]. CholU mostly affects patients with age onset in their second to third decade [9].…”

Background. Cholinergic urticaria (CholU) is a subset of chronic inducible urticaria characterized by the recurrent pinpoint-sized wheals that are induced by exercising or increasing core body temperature. Currently, the data of CholU in tropical climate is still limited. Objective. To investigate the clinical features and natural course of CholU in a tropical country. Materials and Methods. This retrospective chart review study analyzed the data of CholU patients aged over 18 years who visited Siriraj Urticaria Clinic, Siriraj Hospital, Bangkok, Thailand, between January 2007 and September 2019. Demographic data, clinical presentations, and results of provocation tests and other laboratory investigations were evaluated and compared with other studies reported in temperate zones. Results. Sixteen out of 2,175 chronic urticaria patients (0.7%) were diagnosed with CholU. The median age of CholU patients was 28.0±11.7 years with male predominance (56.3%). Three patients (18.8%) had a history of atopy. Fifteen patients (93.8%) were positive to the exercise provocation test. Nonsedating antihistamine drugs were a main treatment (73.8%). Six patients (37.5%) were in remission at the time of the study, with a mean duration 4.3 years. The Kaplan-Meier survival analysis demonstrated that 12.5%, 35.5%, and 67.9% of patients would have disease remission within 1 year, 5 years, and 13 years, respectively. Conclusions. The prevalence of CholU differs in each geographic region and is found to be low in tropical countries with a median duration 4.3 years. The prevalence of atopy and anaphylaxis with CholU is also lower in tropical countries than in temperate.

“…The prevalence of cholinergic urticaria in the general population is also debated, but one study has suggested that 11% of young adults can have mild disease [20]. Conversely, a recent Korean epidemiological study has estimated that the prevalence of dermatographism and cholinergic urticaria in the general population is 0.12% and 0.025% respectively [21]. As cholinergic urticaria is produced by elevation/reduction of core body temperature, it is also reasonable to see an association between cholinergic and cold-induced urticaria.…”

BackgroundCold-induced urticaria is a significant condition, especially among young females. Despite the morbidity of this disease, studies that fully characterize the disease are limited.MethodsWe analyzed the characteristics of patients diagnosed with cold-induced urticaria at a community-based allergy practice in Vancouver, BC, Canada between 2003 and 2016. Detailed patient history, diagnostic measures and treatment were evaluated.ResultsA total of 50 patients were found to have active cold-induced urticaria with a median age of 28.5 (range 2–67) years and 35 patients (70%) were female. 16 patients (32%) had co-occurring physical urticarias while 26 patients (52%) had secondary allergic diagnoses and 3 patients (6%) were thought to have a provoking factor. Of those with a clinical history of suspected cold-induced urticaria that were evaluated with ice cube testing, a positive test was obtained in 84.7% of patients. Treatment was largely with non-sedating antihistamines, with the majority of patients receiving this modality.ConclusionsCold-induced urticaria is a complex disease with significant overlap with other chronic inducible urticarias and other allergic diseases. Diagnostic testing shows inconsistent results and the mainstay of treatment consists of non-sedating antihistamines, with other options available for those who do not respond.

“…One reason for female predominance could be that 35-40% of chronic urticaria have an autoimmune origin [ 4 ]. In contrast, cholinergic urticaria had been slightly more common in males compared to females in another study [ 21 ].…”

“…In the current study, 70% of children had urticarial symptoms for at least one-year duration. However, a study from South Korea reported that most children had symptoms for less than one-year duration [ 21 ]. This could be due to the fact that most children in the current study were initially managed by general practitioners before they were referred to paediatricians.…”
