“…The authors of this study pointed out that their study was undertaken in a region of Mexico that is according to their assessment predestined for allergic diseases due to climatic reasons . Opposite to the data from Mexico, a recently published study from Argentina yielded a point prevalence of only 0.29% among a highly selective sample in Buenos Aires, that is, members of a private health maintenance organization . Northern America showed the lowest point prevalence.…”

Background and objectives Urticaria is a frequent skin condition, but reliable prevalence estimates from population studies particularly of the chronic form are scarce. The objective of this study was to systematically evaluate and summarize the prevalence of chronic urticaria by evaluating population‐based studies worldwide. Methods We performed a systematic search in PUBMED and EMBASE for population‐based studies of cross‐sectional or cohort design and studies based on health insurance/system databases. Risk of bias was assessed using a specific tool for prevalence studies. For meta‐analysis, we used a random effects model. Results Eighteen studies were included in the systematic evaluation and 11 in the meta‐analysis including data from over 86 000 000 participants. Risk of bias was mainly moderate, whereas the statistical heterogeneity (I2) between the studies was high. Asian studies combined showed a higher point prevalence of chronic urticaria (1.4%, 95%‐CI 0.5‐2.9) than those from Europe (0.5%, 0.2‐1.0) and Northern American (0.1%, 0.1‐0.1). Women were slightly more affected than men, whereas in children < 15 years we did not find a sex‐specific difference in the prevalence. The four studies that examined time trends indicated an increasing prevalence of chronic urticaria over time. Conclusions On a global level, the prevalence of chronic urticaria showed considerable regional differences. There is a need to obtain more sex‐specific population‐based and standardized international data particularly for children and adolescents, different chronic urticaria subtypes and potential risk and protective factors.

The clinical epidemiological characteristics of chronic urticaria (CU) in different populations were not completely consistent, and the epidemiological characteristics of CU were very complex. At present, there were some patient-based studies on CU, but few natural population-based studied in the world. This study aimed to analysis the prevalence of self-reported CU among adults in grasslands of northern China and its closely related factors. A multistage and proportionately stratified random sampling with a field interviewer-administered survey study was performed together with skin prick tests (SPT) and measurements of the daily pollen count. A total of 3406 subjects completed the study. The prevalence of self-reported CU was 5.61% (n = 191), which was higher in women than that of men (6.91% vs 4.08%, X2 = 12.785, P < .001). Seasonal or seasonal aggravation CU accounted for 110 (57.59%) patients. Pollen dispersal season was basically consistent with the peak season of CU, but there was no significant difference in the positive rate of pollen SPT between CU with seasonal or seasonal aggravation symptom and CU with free of symptom (X 2 = 0.425, P = .51), as well as between CU with seasonal or seasonal aggravation symptom and perennial CU (X 2 = 0.439, P = .51). Eczema (odds ratio [OR] = 2.807, P < .001), chronic diarrhea (OR = 2.486, P < .01), food allergy history (OR = 1.890, P < .01), history of family allergy (OR = 1.800, P < .001), and conjunctivitis (OR = 1.749, P < .01) were closely related to CU. This investigation provided the factors closely related to CU, and provided certain ideas for further research on the etiology and prevention of CU.

The management of chronic urticaria (CU) has been controversial. Recently updated international guidelines propose evidence‐based diagnosis and treatment. Nevertheless, dermatologists have heterogeneous approaches to managing CU. To estimate the percentage of dermatologists who have an optimal approach to CU according to the international guidelines, and to explore the variables associated with optimal management a cross‐sectional study using a 17‐question survey was delivered by email to dermatologists from Argentina. Optimal first, second, and third line treatment were considered when dermatologists chose a nonsedative antihistamine; increased the dosage of nonsedative antihistamines, and added omalizumab, respectively. Logistic regression was used to identify variables associated with optimal management. A total of 165 questionnaires were available for analysis. An optimal first, second, and third‐line treatment approach was identified in 50%, 35%, and 15% of the dermatologists, respectively. The dermatologists' age being above 55 years old (OR: 0.12, 95% CI: 0.01–0.99, p .005) and having more than 5 years of expertise (OR: 0.4, 95% CI: 0.19–0.81, p .001) were significantly associated with a suboptimal approach in second‐line treatment. We could not find variables associated with an optimal first or third‐line treatment. The real‐life management of CU in Argentina is partly suboptimal according to the international guidelines.
