RESUMO
Introduction: The SARS-CoV-2 epidemic has unquestionably left a significant mark on the global healthcare system. Implementation of the commonly available vaccinations against COVID-19 is intended to reduce the risk of a severe course of the disease. Due to a very brief development period of the new vaccines, concerns have appeared among the public with regard to the possible adverse effects of the newly-developed preparations, as well as to the risks of causing allergic reactions. Regular medical observation during the Hymenoptera venom immunotherapy provides significant possibilities to note any potential adverse effects of vaccines against COVID-19, as well as of complications of an experienced SARS CoV-2 infection. Aim: To assess the issues connected with vaccination against COVID-19, complications following vaccination, as well as incidence and course of the disease among patients undergoing venom immunotherapy (VIT) due to an allergy to Hymenoptera venom. Material and methods: We investigated 37 persons aged 19 to 70 (20 women; 17 men) undergoing Hymenoptera venom immunotherapy in our department. Results: 21.6% have experienced an infection with the SARS-CoV-2 virus, confirmed by a diagnostic test. No person participating in the study had experienced a severe infection which would require hospitalization. Elderly people have been vaccinated statistically significantly more often than young people. Conclusions: The risk related to vaccination in this group of patients does not seem to be higher than in the general population.
RESUMO
BACKGROUND: Angioedema (AE) manifests with intermittent, localized, self-limiting swelling of the subcutaneous and/or submucosal tissue. AE is heterogeneous, can be hereditary or acquired, may occur only once or be recurrent, may exhibit wheals or not, and may be due to mast cell mediators, bradykinin, or other mechanisms. Several different taxonomic systems are currently used, making it difficult to compare the results of studies, develop multicenter collaboration, and harmonize AE treatment. OBJECTIVE: We developed a consensus on the definition, acronyms, nomenclature, and classification of AE (DANCE). METHODS: The initiative involved 91 experts from 35 countries and was endorsed by 53 scientific and medical societies, and patient organizations. A consensus was reached by online discussion and voting using the Delphi process over a period of 16 months (June 2021 to November 2022). RESULTS: The DANCE initiative resulted in an international consensus on the definition, classification, and terminology of AE. The new consensus classification features 5 types and endotypes of AE and a harmonized vocabulary of abbreviations/acronyms. CONCLUSION: The DANCE classification complements current clinical guidelines and expert consensus recommendations on the diagnostic assessment and treatment of AE. DANCE does not replace current clinical guidelines, and expert consensus algorithms and should not be misconstrued in a way that affects reimbursement of medicines prescribed by physicians using sound clinical judgment. We anticipate that this new AE taxonomy and nomenclature will harmonize and facilitate AE research and clinical studies, thereby improving patient care.

BACKGROUND: Chronic spontaneous urticaria (CSU) is unpredictable and can severely impair patients' quality of life. Patients with CSU need a convenient, user-friendly platform to complete patient-reported outcome measures (PROMs) on their mobile devices. CRUSE® , the Chronic Urticaria Self Evaluation app, aims to address this unmet need. METHODS: CRUSE® was developed by an international steering committee of urticaria specialists. Priorities for the app based on recent findings in CSU were defined to allow patients to track and record their symptoms and medication use over time and send photographs. The CRUSE® app collects patient data such as age, sex, disease onset, triggers, medication, and CSU characteristics that can be sent securely to physicians, providing real-time insights. Additionally, CRUSE® contains PROMs to assess disease activity and control, which are individualised to patient profiles and clinical manifestations. RESULTS: CRUSE® was launched in Germany in March 2022 and is now available for free in 17 countries. It is adapted to the local language and displays a country-specific list of available urticaria medications. English and Ukrainian versions are available worldwide. From July 2022 to June 2023, 25,710 observations were documented by 2540 users; 72.7% were females, with a mean age of 39.6 years. At baseline, 93.7% and 51.3% of users had wheals and angioedema, respectively. Second-generation antihistamines were used in 74.0% of days. CONCLUSIONS: The initial data from CRUSE® show the wide use and utility of effectively tracking patients' disease activity and control, paving the way for personalised CSU management.
RESUMO
BACKGROUND: Concern about disease exacerbations and fear of reactions after coronavirus disease 2019 (COVID-19) vaccinations are common in chronic urticaria (CU) patients and may lead to vaccine hesitancy. OBJECTIVE: We assessed the frequency and risk factors of CU exacerbation and adverse reactions in CU patients after COVID-19 vaccination. METHODS: COVAC-CU is an international multicenter study of Urticaria Centers of Reference and Excellence (UCAREs) that retrospectively evaluated the effects of COVID-19 vaccination in CU patients aged ≥18 years and vaccinated with ≥1 dose of any COVID-19 vaccine. We evaluated CU exacerbations and severe allergic reactions as well as other adverse events associated with COVID-19 vaccinations and their association with various CU parameters. RESULTS: Across 2769 COVID-19-vaccinated CU patients, most (90%) received at least 2 COVID-19 vaccine doses, and most patients received CU treatment and had well-controlled disease. The rate of COVID-19 vaccination-induced CU exacerbation was 9%. Of 223 patients with CU exacerbation after the first dose, 53.4% experienced recurrence of CU exacerbation after the second dose. CU exacerbation most often started <48 hours after vaccination (59.2%), lasted for a few weeks or less (70%), and was treated mainly with antihistamines (70.3%). Factors that increased the risk for COVID-19 vaccination-induced CU exacerbation included female sex, disease duration shorter than 24 months, having chronic spontaneous versus inducible urticaria, receipt of adenovirus viral vector vaccine, having nonsteroidal anti-inflammatory drug/aspirin intolerance, and having concerns about getting vaccinated; receiving omalizumab treatment and Latino/Hispanic ethnicity lowered the risk. First-dose vaccine-related adverse effects, most commonly local reactions, fever, fatigue, and muscle pain, were reported by 43.5% of CU patients. Seven patients reported severe allergic reactions. CONCLUSIONS: COVID-19 vaccination leads to disease exacerbation in only a small number of CU patients and is generally well tolerated.

INTRODUCTION: The aim of this cohort study was to evaluate the relationship between anthropometric and body composition parameters and anti-SARS-CoV-2 IgG titers in a group of females who were vaccinated against COVID-19 with two doses of ChAdOx1 vaccine and then boosted with the BNT162b2 vaccine. MATERIALS AND METHODS: The study group consisted of 63 women. Basic demographic and clinical data were collected. To assess the anti-SARS-CoV-2 immunoglobulin G titers following the vaccination, five blood draws were performed: 1) before the first dose, 2) before the second dose, 3) 14-21 days after the primary vaccination, 4) before the booster, and 5) 21 days after the booster. Blood samples were analyzed using a two-step enzymatic chemiluminescent assay. Body mass index and body composition were evaluated using bioelectrical impedance analysis. To select the most distinguishing parameters and correlations between anthropometric and body composition parameters and anti-SARS-CoV-2 IgG titers, factor analysis using the Principal Component Analysis was conducted. RESULTS: Sixty-three females (mean age: 46.52 years) who met the inclusion criteria were enrolled. 40 of them (63.50%) participated in the post-booster follow-up. After receiving two doses of the ChAdOx1 vaccine, the study group's anti-SARS-CoV-2 IgG titers were 67.19 ± 77.44 AU/mL (mean ± SD), whereas after receiving a heterologous mRNA booster, the level of anti-SARS-CoV-2 IgG titers was about three-times higher and amounted to 212.64 ± 146.40 AU/mL (mean ± SD). Our data shows that seropositivity, obesity, non-fat-related, and fat-related body composition parameters all had a significant effect on the level of IgG titer after a two-dose vaccination of ChAdOx1. However, only non-fat-related and fat-related body composition parameters had a significant effect on the IgG titer after booster vaccination. CONCLUSION: COVID-19 infection before the first dose of vaccination is not related to IgG titer after booster administration. Body composition has a significant effect on the production of anti-SARS-CoV-2 IgG after booster vaccination in females.

Microvascular complications of diabetes seem to be clustered and put patients at higher risk of developing cardiovascular disease (CVD). This was a questionnaire-based study designed to screen for the presence of diabetic peripheral neuropathy (DPN), defined as the score in the Michigan Neuropathy Screening Instrument (MNSI) above 2, and to evaluate its association with other complication of diabetes, including CVD. There were 184 patients included into the study. The prevalence of DPN in the study group was 37.5%. The regression model analysis revealed that the presence of DPN was significantly associated with the presence of diabetic kidney disease (DKD) (Pâ¯=â¯0.0034;) and patient's age (P < 0.0001). Thirty-four patients (49.3%) with MNSI score >2 were diagnosed with CVD in comparison to 24 (20.1%) subjects with MNSI score ≤ 2 (Pâ¯=â¯0.00006). In case of having one diabetes complication diagnosed, it is important to screen for others, including macrovascular ones.

RESUMO
BACKGROUND: Research shows that in most people, two-dose vaccination helps to shape the humoral response to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). Further studies are required to learn about the vaccine's effectiveness after boosting. METHODS: We conducted a prospective study among 103 healthcare workers (HCWs) from a regional multi-specialty hospital vaccinated with three doses of the BNT162b2 vaccine. We compared their immunoglobulin G (IgG) titers 14 days after the second dose with those 21 days after the booster. We also compared their anthropometric and body composition parameters with IgG concentrations at the same time points. RESULTS: Twenty-one days after the booster, all study participants were seropositive. Their mean IgG antibody titers were significantly lower than 14 days after the second dose (158.94 AU/mL ± 90.34 AU/mL vs. 505.79 AU/mL ± 367.16 AU/mL). Post-booster Spearman's correlation analysis showed a significantly weak correlation between the IgG antibody titer and parameters related to muscle tissue and adipose tissue (including body fat mass). CONCLUSIONS: The BNT162b2 booster stimulates the humoral response to a lesser extent than the two-dose BNT162b2 primary vaccination. The adipose and muscle tissue parameters show a weak positive correlation with the SARS-CoV-2 IgG antibody titers.
RESUMO
OBJECTIVES: The aim of thestudy was to assess the relationship between symptoms of depression, the level of sense of coherence (SOC) and the quality of life in patients with allergic diseases. MATERIAL AND METHODS: The study involved 50 bronchial asthma patients, 72 patients with seasonal allergic rhinitis, and 48 patients with atopic dermatitis. The control group consisted of 50 healthy volunteers. The mental status and quality of life were assessed by questionnaires: Short Form-36 Health Status Survey (SF-36), Beck Depression Inventory (BDI), Sense of Coherence-29 (SOC-29). RESULTS: Mean depression severity values were higher in allergic rhinitis patients and atopic dermatitis patients than in the control group. Patients in the latter group also showed higher rates of depression than those with bronchial asthma. In all study groups, statistically significantly lower values of sense of coherence were demonstrated compared to healthy subjects. There were no differences in the values of sense of coherence, in comparisons between the study groups. In all patient groups, lower values in physical functioning (PCS) of the quality of life scale were observed compared to the control group. The severity of symptoms of depression in all groups showed negative correlations with quality of life parameters and a sense of coherence. In addition, the SOC value correlated negatively with the parameters of mental functioning (MCS) of the quality of life scale. CONCLUSIONS: (1) Patients with atopic dermatitis showed the greatest severity of depressive symptoms. (2) Patients with seasonal allergic rhinitis showed abetter quality of life than patients with chronic bronchial asthma and patients with atopic dermatitis. (3) Low level of sense of coherence in patients suffering from allergic diseases and the occurrence of symptoms of depression can worsen the quality of life.

BACKGROUND: This study aimed to investigate the early and longitudinal humoral response in Healthcare Workers (HCWs) after two doses of the BNT162b2 vaccine and to assess the association between metabolic and anthropometric parameters and the humoral response after vaccination. METHODS: The study included 243 fully vaccinated HCWs: 25.50% previously infected with SARS-CoV-2 (with prior history of COVID-19-PH) and 74.40%-uninfected, seronegative before the first vaccination (with no prior history of COVID-19-NPH). IgG antibodies were measured, and sera were collected: prior to the vaccination, 21 days after the first dose, and 14 days and 8 months after the second dose. RESULTS: 21 days after the first dose, 90.95% of individuals were seropositive; 14 days after the second dose, persistent immunity was observed in 99.18% HCWs, 8 months after complete vaccination-in 61.73%. Statistical analysis revealed that HCWs with PH had a greater chance of maintaining a humoral response beyond eight months after vaccination. Increased muscle mass, decreased fat mass, and younger age may positively affect long-term immunity. Smokers have a reduced chance of developing immunity compared to non-smokers. CONCLUSIONS: Fully vaccinated HCWs with PH are more likely to be seropositive than fully inoculated volunteers with NPH.

Background: Monitoring the effects of treatment on disease activity, impact, and control in patients with chronic spontaneous urticaria (CSU) is essential. We do not have enough information on how these features of CSU and its response to treatment are linked. Also, there is no information on how recurrent angioedema or coexisting chronic inducible urticaria (CIndU) affect their relation. The aim of this study was to analyse the link between disease activity, impact, and control in CSU patients and possible effects of recurrent angioedema and comorbid CIndU. Methods: To perform these analyses, we validated the Polish version of the Urticaria Control Test (UCT) in 106 chronic urticaria patients. The relationship between CSU activity, impact, and control was assessed in regard to recurrent angioedema and coexisting CIndU. Results: The Polish UCT showed high levels of validity, reliability, and sensitivity to change. Disease activity, impact, and control as well as their changes, assessed by the UAS, the CU-Q2oL, and the UCT, respectively, were strongly correlated. Recurrent angioedema or comorbid CIndU did not significantly affect the link of CSU activity, impact, and control or the relation of their changes. Conclusions: In CSU, there is a strong, albeit not perfect correlation of disease activity, impact, and control, which underlines the need to assess all 3 features of the disease in routine clinical practice. Recurrent angioedema and comorbid CIndU, which are both common and relevant in CSU, do not affect how disease activity, impact and control in patients with CSU are related to each other.
RESUMO
Airway inflammation is related to increased nitric oxide production. It can be assessed noninvasively with exhaled nitric oxide measurement. As airway inflammation was supposed to be present in chronic urticaria and angioedema patients we hypothesized increased exhaled nitric oxide in this group. Twenty-six symptomatic chronic urticaria patients with an acute episode of pharynx angioedema (17 women and 9 men, median age 35) were included in the study group. None of the patients reported a history of asthma, allergic rhinitis or cigarette smoking. The control group consisted of 29 non-smoking healthy subjects (19 women and 10 men, median age 22) without any history of atopy. Exhaled nitric oxide measurement was performed in all subjects. Exhaled nitric oxide levels in the angioedema group did not differ statistically significantly from those detected in healthy subjects (15.5 ppb and 17.0 ppb respectively). Our results indicate the lack of airway inflammation in chronic urticaria patients with pharynx angioedema.
RESUMO
OBJECTIVES: The aim of the study was to evaluate pro-health behaviors as protective measures against symptoms of anxiety and depression in a group of health care workers during the first wave of the SARS-CoV-2 virus pandemic. METHODS: The group of 114 people participated in the study, including 46 medical doctors aged 41.10 ± 11.89 and 68 nurses aged 48.16 ± 8.54 years.The following scales were used for the research: the Health Behavior Inventory (HBI), the Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI). RESULTS: Taking into consideration health behaviors, an average score of 79.61 ± 13.08 points in HBI was obtained. In the BDI questionnaire, the respondents obtained an average of 3.7 ± 4.65 points. In the STAI questionnaire, in the part related to state anxiety, the mean result in the study group was 38.08 ± 9.46 points, and for trait anxiety 38.35 ± 8.44 points. Taking into account the components of HBI, only the results obtained in the subscales: positive mental attitude (PMA) and pro-health activities (PhA) correlated negatively with the results obtained in the STAI and BDI scales. Moreover, the pro-health effect of PMA on the symptoms of anxiety and depression was observed. CONCLUSIONS: No significant intensification of anxiety and depression symptoms was observed among medical personnel during the first wave of the pandemic. Health-promoting behaviors, and especially positive mental attitudes, may play a protective role in relation to the symptoms of anxiety and depression in a stressful situations.

This update and revision of the international guideline for urticaria was developed following the methods recommended by Cochrane and the Grading of Recommendations Assessment, Development and Evaluation (GRADE) working group. It is a joint initiative of the Dermatology Section of the European Academy of Allergology and Clinical Immunology (EAACI), the Global Allergy and Asthma European Network (GA²LEN) and its Urticaria and Angioedema Centers of Reference and Excellence (UCAREs and ACAREs), the European Dermatology Forum (EDF; EuroGuiDerm), and the Asia Pacific Association of Allergy, Asthma and Clinical Immunology with the participation of 64 delegates of 50 national and international societies and from 31 countries. The consensus conference was held on 3 December 2020. This guideline was acknowledged and accepted by the European Union of Medical Specialists (UEMS). Urticaria is a frequent, mast cell-driven disease that presents with wheals, angioedema, or both. The lifetime prevalence for acute urticaria is approximately 20%. Chronic spontaneous or inducible urticaria is disabling, impairs quality of life, and affects performance at work and school. This updated version of the international guideline for urticaria covers the definition and classification of urticaria and outlines expert-guided and evidence-based diagnostic and therapeutic approaches for the different subtypes of urticaria.

BACKGROUND: Angioedema coexisting chronic spontaneous urticaria (CSU) is proved to result in patient anxiety occurrence, but the mechanisms and susceptibility patterns are unknown. Sense of coherence (SOC) is one of methods of coping with stress and is defined as a person's general orientation toward life. We decided to assess SOC disturbances in CSU patients in the context of possible angioedema association. METHODS: The study comprised 71 CSU subjects. To analyze disease activity, the Urticaria Activity Score seven-day assessment questionnaire (UAS7) was used. For anxiety assessment, the STAI questionnaire was used. The SOC-29 questionnaire, consisting of questions related to comprehensibility (SOC-C), manageability (SOC-M), and meaningfulness (SOC-Mf), was used to analyze SOC parameters (SOC-T). RESULTS: In patients with coexisting angioedema, we observed statistically significantly lower values of SOC-Mf and SOC-T in comparison to the wheals only group. In the angioedema group, we noticed significant negative correlations between SOC-M and SOC-Mf, as well as SOC-T values and anxiety. In the wheals only group, we proved statistically significant correlations between SOC-Mf and SOC-T and anxiety assessed as a state. CONCLUSIONS: It is necessary to identify CSU patients manifesting angioedema as they are more likely to have impaired SOC. Lower SOC in this specific group of patients can be related to anxiety symptoms occurrence and should probably be an indication for psychological support.
RESUMO
Chronic spontaneous urticaria (CSU) is defined using clinical symptoms as spontaneous occurrence of itchy wheals and/or angioedema for at least 6 weeks. Angioedema is underdiagnosed in CSU patients, and its presence has significant negative impact on health-related quality of life, daily activities, health care resource utilization, and work. Various cytokines have been found to be involved in pathogenesis of CSU. To study levels of interleukin (IL)-10 and IL-18 in CSU patients and to look for the differences in CSU subgroups divided with regard to angioedema reoccurrence, we included consecutive CSU patients into the study. To assess disease activity, urticaria activity score was used. In addition, we calculated disease duration time. In all groups, Il-10 and Il-18 serum concentrations were measured. The study involved 52 patients with CSU and 47 healthy volunteers. The IL-10 level was statistically significantly higher in patients with CSU compared to the control group. There were no significant differences in level of IL-18 between those groups. Comparison of patients with CSU and angioedema with those without angioedema showed no significant differences in level of IL-10 and IL-18. We see the need for further studies of serum levels of IL-10 and IL-18 to better understand the pathogenesis of the disease and to find markers useful in predicting the symptom type in the course of CSU.

(1) Background: Detection of asymptomatic or subclinical human coronavirus SARS-CoV-2 infection in healthcare workers (HCWs) is crucial for understanding the overall prevalence of the new coronavirus and its infection potential in public (non-infectious) healthcare units with emergency wards. (2) Methods: We evaluated the host serologic responses, measured with semi-quantitative ELISA tests (IgA, IgG, IgM abs) in sera of 90 individuals in Hospital no. 4 in Bytom, 84 HCWs in the University Hospital in Opole and 25 in a Miasteczko Slaskie local surgery. All volunteers had negative RT-PCR test results or had not had the RT-PCR test performed within 30 days before sampling. The ELISA test was made at two different time points (July/August 2020) with a 2-weeks gap between blood collections to avoid the "serological window" period. (3) Results: The IgG seropositivity of asymptomatic HCWs varied between 1.2% to 10% (Opole vs. Bytom, p < 0.05; all without any symptoms). IgA seropositivity in HCWs was 8.8% in Opole and 7.14% in Bytom. IgM positive levels in HCWs in Opole and Bytom was 1.11% vs. 2.38%, respectively. Individuals with IgA and IgM seropositivity results were observed only in Opole (1.19%). More studies are needed to determine whether these results are generalizable to other populations and geographic as well as socio-demographic locations. (4) Conclusions: 100% of IgG(+) volunteers were free from any symptoms of infection in the 30 days before first or second blood collection and they had no awareness of SARS-CoV-2 infection. Asymptomatic HCWs could spread SARS-CoV-2 infection to other employees and patients. Only regular HCWs RT-PCR testing can reduce the risk of SARS-CoV-2 spreading in a hospital environment. The benefit of combining the detection of specific IgA with that of combined specific IgM/IgG is still uncertain.

INTRODUCTION: Urticaria is a clinical entity presenting as wheals, angioedema, or both simultaneously. Elevated D-dimer levels were reported in the course of chronic spontaneous urticaria. Data regarding D-dimer levels in acute urticaria in children are limited. OBJECTIVES: To assess potential associations between duration of glucocorticosteroid (GCS) therapy and D-dimer concentrations in children with acute urticaria. PATIENTS, MATERIALS, AND METHODS: Hospital records of 106 children (59 females), aged 5.57 ± 4.91 years, hospitalized in 2014-2018 were analyzed retrospectively. The study group consisted of pediatric patients admitted to the hospital due to severe acute urticaria resistant to antihistaminic treatment that was ordered in the ambulatory care (out-patient clinic). Patients were divided into subgroups: no GCS treatment, short-duration treatment (up to 5 days) and long-duration treatment (6 and more days) GCS treatment. Simultaneously, patients received antihistaminic drugs. D-dimer level and other inflammatory factors such as white blood cell (WBC) count, platelet (PLT) count, and C-reactive protein (CRP) in each group were analyzed. RESULTS: The D-dimer level was elevated in 51% of cases. In the subgroup with longer GCS treatment, D-dimer concentration was significantly higher in comparison to patients with a shorter GCS course. There were no differences in the distribution of CRP, PLT, and WBC concentrations between these subgroups. CONCLUSIONS: In the studied group of children, there was a tendency for higher D-dimer levels in patients, who required a longer GCS treatment. This finding is hypothesis-generating and requires further investigation to confirm if D-dimers can be used as a prognostic factor in acute urticaria in children.

INTRODUCTION: The COVID-19 pandemic dramatically disrupts health care around the globe. The impact of the pandemic on chronic urticaria (CU) and its management are largely unknown. AIM: To understand how CU patients are affected by the COVID-19 pandemic; how specialists alter CU patient management; and the course of CU in patients with COVID-19. MATERIALS AND METHODS: Our cross-sectional, international, questionnaire-based, multicenter UCARE COVID-CU study assessed the impact of the pandemic on patient consultations, remote treatment, changes in medications, and clinical consequences. RESULTS: The COVID-19 pandemic severely impairs CU patient care, with less than 50% of the weekly numbers of patients treated as compared to before the pandemic. Reduced patient referrals and clinic hours were the major reasons. Almost half of responding UCARE physicians were involved in COVID-19 patient care, which negatively impacted on the care of urticaria patients. The rate of face-to-face consultations decreased by 62%, from 90% to less than half, whereas the rate of remote consultations increased by more than 600%, from one in 10 to more than two thirds. Cyclosporine and systemic corticosteroids, but not antihistamines or omalizumab, are used less during the pandemic. CU does not affect the course of COVID-19, but COVID-19 results in CU exacerbation in one of three patients, with higher rates in patients with severe COVID-19. CONCLUSIONS: The COVID-19 pandemic brings major changes and challenges for CU patients and their physicians. The long-term consequences of these changes, especially the increased use of remote consultations, require careful evaluation.

Recent studies underline a potential role of autoimmune and genetic disturbances in this disorder pathogenesis. Variants in genes related to inflammatory processes may possibly predispose to chronic spontaneous urticaria (CSU) occurrence. The objective of this study was to search for an association of Il1 genes polymorphisms with the pathogenesis of CSU. The examined group consisted of 153 unrelated chronic spontaneous autoreactive urticaria patients. The control group consisted of 104 unrelated healthy volunteers. In all studied subjects, IL1 rs1304037 and rs180058 polymorphisms were examined. The Urticaria Activity Score was used to assess disease intensity. The age of disease onset was also analyzed. Statistically significantly higher prevalence of Il1 rs1304037 TT genotype and T allele among CSU was proved. Similarly, the prevalence of Il1 rs1800587 GG genotype and G allele was statistically significantly higher in the CSU group. Haplotype combination rs1304037C/rs1800587G was statistically significantly more frequent in CSU, whereas rs1304037C/rs1800587A revealed statistically significantly less frequent occurrence in CSU. We did not observe any relationship between Il1 genotypes and the disease severity or age of disease onset. We are the first to suggest a significant role of IL1 gene polymorphisms in the susceptibility to CSU. This observation may lead to a better pathogenesis understanding and more effective treatment. We recommend further studies on other polymorphisms in chronic urticaria to analyze the role of the genetic mechanisms in the pathogenesis of this disorder.
