ABSTRACT
Introduction: Coronavirus disease 2019 (COVID-19) has caused thousands of deaths since it was declared as a pandemic. Recently it continues to be one of the most followed topics in the world in terms of its course and treatment. Favipiravir is a broad-spectrum anti-viral agent that has been shown to be effective against various Coronaviruses in vitro. However, as with any drug use, side effects may develop with the use of favipravir treatment. Case Report: We reported a 55-year-old female patient with acute urticarial with angioedema whom had COVID-19 pneumonia. She had no history of allergy, atopy, previous similar episodes or family history of hereditary angioedema. There is no drug or food consumption that may be suspicious in terms of allergy described by the patient other than favipravir. Conclusion(s): As far as we know, it is the first case reported from our country. Since there is no specific examination for differential diagnosis, we cannot distinguish as a rare side effect due to favipiravir treatment or COVID-19 cutaneous manifestation. As a result, studies involving more cases of COVID-19 skin findings are needed.© Copyright 2020 by Emergency Physicians Association of Turkey.
ABSTRACT
Allergic and hypersensitivity reactions induced by COVID-19 vaccines are increasingly reported and some patients may develop prolonged urticarial reactions following COVID-19 vaccination. Herein, we investigated the risk factors and immune mechanisms for patients with COVID-19 vaccines-induced immediate allergy and chronic urticaria (CU). We prospectively recruited and analyzed 129 patients with COVID-19 vaccine-induced immediate allergic and urticarial reactions as well as 115 COVID-19 vaccines-tolerant individuals from multiple medical centers during 2021-2022. The clinical manifestations included acute urticaria, anaphylaxis, and delayed to chronic urticaria developed after COVID-19 vaccinations. The serum levels of histamine, IL-2, IL-4, IL-6, IL-8, IL-17A, TARC, and PARC were significantly elevated in allergic patients comparing to tolerant subjects (P-values=4.5x10-5-0.039). Ex vivo basophil revealed that basophils from allergic patients could be significantly activated by COVID-19 vaccine excipients (polyethylene glycol 2000 and polysorbate 80) or spike protein (P-values from 3.5x10-4 to 0.043). Further BAT study stimulated by patients' autoserum showed positive in 81.3% of patients with CU induced by COVID-19 vaccination (P=4.2x10-13), and the reactions could be attenuated by anti-IgE antibody. Autoantibodies screening also identified the significantly increased of IgE-anti-IL-24, IgG-anti-FceRI, IgG-anti-TPO, and IgG-anti-thyroid-related proteins in COVID-19 vaccines-induced CU patients comparing to SARS-COV-2 vaccines-tolerant controls (P-values= 4.6x10-10-0.048). Patients with COVID-19 vaccines-induced recalcitrant CU patients could be successfully treated with anti-IgE therapy. In conclusion, our results revealed that multiple vaccine components, inflammatory cytokines, and autoreactive IgG/IgE antibodies contribute to COVID-19 vaccine-induced immediate allergic and autoimmune urticarial reactions (Minor revision in Journal of Autoimmunity [IF=14.551]).Copyright © 2023
ABSTRACT
Background: Following the use of COVID-19 vaccines worldwide, few cases of severe allergic reactions were reported. According to recent Portuguese guidelines, patients (pts) with suspected allergy to a COVID-19 vaccine component, history of anaphylaxis following vaccination, idiopathic anaphylaxis and mast cell disorders, should be referenced for Immunoallergology evaluation. Fear of a hypersensitivity reaction, especially among pts with allergic disease, is associated with lower vaccine adherence. This study aimed to evaluate BNT162b2 vaccination outcomes in pediatric pts with suspected severe allergic reactions prior to or after vaccination. Method(s): W e c onducted a p rospective s tudy i ncluding p ediatric pts with high risk of allergy to COVID-19 vaccine referred to Immunoallergology Department of a Tertiary Hospital. Demographic data, primary medical conditions and vaccination status were collected. After a detailed assessment by an allergologist, in selected cases, BNT162b2 vaccine administration in hospital facilities was performed, followed by a 1-hour observation period. Result(s): Twenty-two pts were included (18 males, 13.1+/-2.6years;min 7, max 17;13 atopic), referenced mainly from primary care (9) and other specialties (8). Most of the pts were referenced for the first dose of vaccine (18), due to mastocytosis/tryptasemia (5), previous allergic reaction to another vaccine (4), idiopathic anaphylaxis (3), complex comorbidities (2), drug anaphylaxis (1), parental reluctance (1), other (2). Four pts were evaluated for the second dose of COVID-19 vaccine, due to an acute urticaria after the first BNT162b2 vaccine dose. Three pts were eligible, after our evaluation, for primary care vaccination, that occurred without adverse reactions. Regarding the remaining 19 pts eligible for hospital vaccination, 13 were premedicated with oral antihistamines +/- montelukast. Eleven pts received BNT162b2 vaccine in hospital facilities [first dose (9);second dose (2)] with no reported adverse events. Vaccine administration was postponed in 3 pts due to SARS-CoV- 2 infection and 1 due to parental hesitancy. Conclusion(s): Our data support that allergic reactions to BNT162b2 vaccines are rare, even in the pediatric population with high risk of allergic reactions or with a history of previous severe allergic reactions. The favourable safety profile outcomes, along with the risk reduction of allergic reactions, increase vaccine confidence, broadening community protection.
ABSTRACT
Background: Drug hypersensitivity reactions (DHRs) of the immediate type are diagnosed in approximately 1-2% per 100 thousand people. During the COVID-19 pandemic, the use of antibiotics increased, and cases of immediate reactions to these drugs became more frequent. However, due to the lack of medical centers which have the necessary conditions for carrying out provocation tests, the use of in vitro diagnostic methods for hypersensitivity reactions to antibiotics is becoming even more relevant during the pandemic. Flow CAST Basophil Activation Test (BAT) Flow Cytometry can be used for the in vitro detection of immediate type allergic reactions and hypersensitivities to suspected allergens in patients at risk for DHRs. The purpose is to study the possibility of diagnosing hypersensitivity reactions to antibiotics using BAT to antibiotics. Method(s): The Patient Questionnaire Card and the Patient Review Card were used to survey 32 (8.7%) individuals (f -56.3%, m -43.7%) who met the inclusion criteria (the presence of hypersensitivity reactions to beta-lactam antibiotics during the last 3 years). We used Flow CAST to identify the DHRs to beta-lactam antibiotics (Ceftriaxone (conc. 4 mg/ml);Cefuroxime (conc. 2.5 mg/ml);Amoxicillinum (conc. 2.5 mg/ml) from CAST Allergens for CASTFlow CAST) BUHLMANN LABORATORIES AG, Switzerland) in whole blood. Flow cytometric acquisition was performed on a flow cytometer BD FacsCalibur (USA), and 300 basophilic cells were analyzed. Result(s): The most common clinical manifestations included acute urticaria + angioedema (40.6%), generalized urticaria (28.1%), anaphylactic shock (21.9%), bronchospasm (9.4%). The percentage of patients diagnosed with an immediate reaction based on the time of its occurrence was 62.5%, whereas the percentage of patients diagnosed with an immediate reaction based on the clinical manifestations was 81.25%, which was confirmed by positive BAT results (p > 0.05). 68.75% of people with clinical manifestations of reactions to one antibiotic (ceftriaxone or amoxicillin) showed increased values on the BAT test to other beta antibiotics, which may indicate the presence of cross-reactivity between these groups of drugs. Conclusion(s): Diagnostics of immediate hypersensitivity reactions to antibiotics based on in vitro BAT is a highly accurate method. However, in cases of possible cross-reactivity between antibiotics and in cases of delayed reactions, in-depth studies are required.
ABSTRACT
Background: to evaluate the impact of COVID-19 on the course of allergic diseases in children. Method(s): 32 children with allergic diseases who had a coronavirus infection or their parents were surveyed. The questionnaire consisted of questions about the severity of an allergic disease, the severity and complications of a SARS-CoV- 2 infection, the amount of therapy during infection and after infection. The age of patients is from 5 to 16 years (boys 62%, girls 38%). Result(s): Among the respondents were 53.1% (17 patients) with allergic rhinoconjunctivitis (AlRC), 34.3% (11) with atopic bronchial asthma (ABA), 9.5% (3) with atopic dermatitis (AtD) and 3.1% (1) with a history of acute spontaneous urticaria (OK). 71.9% of patients suffered COVID-19 in mild, 25% in moderate and 3.1% in severe forms. Complications: 11 patients were diagnosed pneumonia with lung damage of less than 25%, 1 case of acute urticaria. The analysis of the effect of COVID-19 on the course of allergic diseases was carried out among patients (25 people) who were in remission before infection: with AlRC -15, ABA -8, AtD-2 patients. Patients with AlRC against the background of COVID-19 disease in 40% cases had increase in symptoms, 33.3% noted a preservation of exacerbation after 1 month after the disease, 26.7% after 3 months. Patients with ABA had increase symptoms against the background of COVID-19 occurs in 37.5%, 25% of cases -1 month after the disease, 12.5% of cases after 3 months, Symptoms did not bother and after 6 months. 1 patient with AtD disease had an exacerbation of dermatitis during of COVID-19 and 1 month after infections. Patients who had an exacerbation of an allergic disease against the background of COVID-19, changed drug treatment on a step upper. Reducing the dose of the drugs and and the volume of drug therapy was possible only 3 months after the infection Conclusion(s): Children with allergic diseases have SARS-CoV- 2 occurs in a mild form in most cases. COVID-19 causes exacerbation of AlRC, ABA, AtD in more than 1/3 of patients. Acute urticaria was presented as a complication in one case. Exacerbation of allergopathology against the background of COVID 19 requires a transition to a step above drug therapy for 3 months. Control over the symptoms of allergic diseases is observed 3 to 6 months after the infection.
ABSTRACT
Background: Use of ultrasound contrast agent spread increasingly in worldwide. Although few side effects are published, number of increase anaphylactic reaction is reported. A recent cautionary remark was published about polyethylene glycol (PEG) as culprit for some ultrasound contrast agent hypersensitivity (Krantz et al. JACIP. Avril 2020). A 22 years-old woman was referred for a severe anaphylaxis after a second injection of Sulphur Hexafluoride (SonoVue, Bracco, Milan, Italy). The investigation was performed to explore hepatic multinods. She already had presented with uncomfortable feeling, generalized pruritus and nausea few minutes after the first injection of Sonovue, 10 months earlier. Three months before, she has recieved also a first injection of SPIKEVAX without any reaction. As Sonovue and SPIKEVAX contain PEG, we looked for a hypersensitivity to PEG and RNAm COVID-19 vaccine. Method(s): Skin tests and basophil activation test (BAT) with expression of CD63 were performed for SonoVue, PEG 3350 and 4000 and COMIRNATY. Result(s): Skin tests were negative for all products except the undiluted IDT to COMIRNATY. BAT to PEG and SonoVue were negative but positive to COMIRNATY. Despite a fractioned administration of COMIRNATY, the patient presented with an acute urticaria few minutes after the last injection Conclusion(s): The relationship between PEG, RNAm vaccine, and hypersensitivity to SonoVue is once again highlighted by this new report.

ABSTRACT
Neuroendocrine cell hyperplasia of infancy (NEHI) is a rare interstitial lung disease in children. The clinical features of the disease are characterized by tachypnea, moist rales/crepitus, retraction of compliant chest areas and delayed weight gain. The disease is diagnosed using the NEHI clinical scale coupled with the computed tomography of the chest organs. The clinical manifestations of NEHI regress as the child grows, but may persist up to the age of 10 y/o. The purpose of the research was to characterize the course of NEHI including the features of COVID-19 and the impact of passive smoking in children below the age of 8 y/o. Material(s) and Method(s): a single-center longitudinal study with follow-up observation of 29 patients with NEHI in January 2012 - December 2022 aged 8 months to 8 years old, 21 of which had COVID-19. Result(s): 20 of 29 patients with a known follow-up have undergone the long-term oxygen therapy (LTOT) at home lasting from 2 weeks up to 5.5 years (Me 1 year and 2 months;IQR 6 months - 4.5 years). Bronchial asthma was diagnosed in 2. 8 (28%) were diagnosed with atopic dermatitis, 6 (21%) with mental retardation, 3 (10%) with acute urticaria, and 2 (7%) with allergic rhinitis. Gastroesophageal reflux disease (GERD) was diagnosed in 7, all requiring LTOT. The frequency of episodes of respiratory infection was maximum in the first 2 years of life, amounting to 16 episodes per 2 years (Me 7;IQR 4 to 10), and the maximum frequency of hospitalizations during this age period was 5 (Me 2;IQR 1 to 2). Children-passive smokers were diagnosed with malnutrition more often (75%, p=0.449) and required LTOT more often (75%, p=0.694), were more often hospitalized (42%, p=0.422). Despite the possible need for LTOT patients with NEHI had COVID-19 in the form of nasopharyngitis in the majority of cases (89%). Only 8 out of 14 patients had symptoms of NEHI after 5 years of age, and only 1 out of 5 after 7 years. Malnutrition (body mass index for the age<-2) in the first year of life was diagnosed in 13 (45%) children. Malnutrition persisted in 9 out of 24 (37%) by the second year of life, in 5 out of 19 (26%) by the third year, and in 2 out of 14 (14%) by the fourth year of life. Not a single child died. Conclusion(s): the course of NEHI is characterized by the absence of lethal outcomes, frequent respiratory infections that led to hospitalizations in the first 2 years of life, mild course of COVID-19, regression of clinical symptoms and malnutrition as the child grows, comorbidity with atopic diseases and GERD. The priority should be given to the prevention of passive smoking in children with NEHI.Copyright © 2023, Pediatria Ltd. All rights reserved.
ABSTRACT
Background: As COVID-19 vaccines continue to be administered worldwide, there are an increasing number of studies documenting cutaneous reactions following vaccination. Systemic reactions, such as urticarial diseases, occur. Purpose(s): The main objective of this study was to investigate the association between urticaria and recent vaccination for COVID-19. Method(s): A retrospective chart review examining the association of urticaria and COVID vaccination was conducted. Result(s): We report 17 patients who developed an urticarial reaction following vaccination against COVID and one patient who developed an urticarial reaction following a COVID infection. The vast majority of the patients were women with a mean age of 42.8 years. Conclusion(s): Cutaneous manifestations often follow COVID vaccination and infection. It may be helpful to inquire about recent infections and vaccinations in patients presenting with urticarial diseases. Copyright © 2022 Journal of Dermatology and Dermatologic Surgery.

ABSTRACT
Introduction: Urticaria is a common condition which has clinical overlap with urticarial vasculitis, a rare entity affecting <1% of the population. We report a case of typical acute urticaria evolving into urticarial vasculitis. Case Description: A 58-year-old female with a history of endometrial hyperplasia, Hashimoto's thyroiditis, and asthma was initially seen in Allergy and Immunology clinic following an episode of severe perioperative anaphylaxis, determined to be due to cefazolin. Two months later, she presented with new-onset urticaria and angioedema following a mild self-resolving viral illness. The rash was pruritic, with migratory lesions lasting for <24 hours, and not associated with ecchymoses upon resolution. Initial physical examination was notable for erythematous wheals with blanching. She was started on high dose second-generation antihistamines and received multiple steroid tapers with transient improvement. Four weeks after initiation of the rash, she developed a new-onset burning sensation at its site and subsequently developed painful hyperpigmented purpuric lesions in prior areas of urticaria. She had no associated fever, ocular involvement, abdominal pain, or joint pains. Laboratory values were significant for negative CBC, CMP, ESR, TSH, tryptase, c-KIT mutation analysis, ANA, C1q, C3, C4, and SARS-CoV-2 nucleocapsid antibodies. Extensive autoimmune workup was negative. Skin biopsy revealed leukocytoclastic vasculitis consistent with urticarial vasculitis. Patient was started on omalizumab with initial improvement. Discussion(s): Although initially presenting with acute urticaria, the progression of atypical urticarial symptoms warranted consideration of alternative diagnoses, including urticarial vasculitis. This case highlights the clinical overlap between acute/chronic urticaria and urticarial vasculitis which may result in a delay in diagnosis. Copyright © 2022
ABSTRACT
Introduction: COVID 19 vaccines are considered as an important medical advance in healthcare. It is the most promising approach for curbing the COVID-19 pandemic. However, as the number of people receiving vaccination rises, we are inevitably faced with increasing adverse drug reactions. The most common adverse reactions to vaccines are non-allergic, as flu like-symptoms and injection site reactions. Immediate hypersensitivity reactions are fortunately rare [1,2]. Objective(s): The aim of our work was to study clinical characteristics of acute urticaria following COVID-19 vaccines reported to the Tunisian National Center of Pharmacovigilance. Method(s): We conducted a retrospective study involving all cases of acute urticaria related to COVID-19 vaccines since the onset of the vaccine campaign in March 2021 to May 2022. Result(s): This study included 70 patients. Age ranged from 15 to 77 years old with a median age of 26 years. There were 51 women, and the sex ratio M/F was 0.37. The onset of urticaria varied from few hours to 17 days following vaccine injection with an average delay of 4 days. In 56 cases, urticaria occurred following 1st shot, in 10 cases following the 2nd dose and one case was reported following the 3rd dose of vaccine. This data was not mentioned in 3 cases. Outcome was favorable in 57 cases and unknown in 13 cases. Involved vaccines were Pfizer/BioNTech (47.14%), SPIKEVAX COVID-19 Vaccine Moderna (20%), AstraZeneca COVID-19 vaccine (15.71%), COVID-19 Vaccine Janssen (11.42%), CORONAVAC SINOVAC COVID-19 VACCINE (2.85%) and Sputnik V (2.85%). Urticaria was isolated in 58 cases, was associated with angioedema in 7 cases, and with fever in 5 cases. Conclusion(s): Our work showed a very low number of cases of acute urticaria following Covid-19 immunization. The Center for Disease Control and Prevention recommend, in patients who had even within 4 hours of getting vaccinated a non-severe allergic reaction to COVID-19 Vaccine to receive another dose of the same vaccine under medical surveillance. This is suggesting a non-specific mechanism.
ABSTRACT
SESSION TITLE: Poster Cases in Asthma and Allergy SESSION TYPE: Case Report Posters PRESENTED ON: 10/17/2022 12:15 pm - 01:15 pm INTRODUCTION: Anaphylaxis is an acute, potentially life-threatening, systemic allergic reaction that presents as a multitude of manifestations after exposure to an allergen. It is rare to have an anaphylactic reaction to the SARS-Cov-2 vaccine, however, we present a patient who had a prolonged anaphylactic reaction to the SARS-CoV-2 virus itself. CASE PRESENTATION: A 23-year-old female with past medical history of chronic idiopathic urticaria and dermatographism presented with fatigue, rash, rhinitis, and lip swelling in the setting of being COVID-19 positive. She had received two doses of the Pfizer-BioNTech COVID-19 vaccine nine months prior without any adverse affects. During the SARS-CoV-2 Omicron variant surge, the patient was exposed to a family member who had contracted COVID-19 infection. Two days prior to presentation, she started having a diffuse rash throughout her body. In the Emergency Department, she was given IM epinephrine x2, IV Solu-Medrol and IV Benadryl with temporary improvement in her symptoms. She developed hypotension that required initiation of a continuous epinephrine infusion and was admitted to the Medical Intensive Care Unit. Each time the epinephrine was held, generalized urticaria recurred and she would become hypotensive with her systolic blood pressure decreasing below 80 mmHg. The urticaria completely resolved and her blood pressure improved when the epinephrine infusion was restarted. The patient was treated with remdesivir, Solu-Medrol, loratadine, and famotidine. She was able to be weaned off the epinephrine infusion over the course of four days. Immunological workup was unremarkable apart from elevation of IL-10 on her cytokine panel. DISCUSSION: The symptoms and syndromes associated with COVID-19 infection remain diverse and while urticaria has been a documented manifestation of the virus, it is uncommon (1). There is a single case report of an anaphylactic reaction in response to COVID-19 (2). Given our patient's symptoms were temporally related to the COVID-19 infection, we believe the SARS-COV-2 virus was the trigger. She did not have any other exposure during this time. This case is unique in that the virus not only triggered the urticaria, but that her symptoms persisted for four days. After receiving antiviral therapy plus steroids and antihistamines, her symptoms finally resolved. The SARS-COV-2 virus itself is primarily attacked by immune cells, including mast cells, which release an array of proinflammatory cytokines (3). We postulate that in our patient, her history of chronic urticaria predisposed her to an exaggerated inflammatory response. CONCLUSIONS: SARS-CoV-2 has clinically presented itself in a multitude of ways across many disciplines. In a patient with a history of urticaria, prolonged anaphylactic symptoms can be triggered by the virus itself. Reference #1: Adeliño R., Andrés-Cordón J.F., De la Cruz Martínez C.A.

ABSTRACT
Urticaria multiforme, first described in 1997, also called acute ring urticaria, is a clinical variant of acute urticaria. We relate the case of a 16-year-old adolescent with an extensive pruritic eruption of erythematous annular lesions of variable shapes, arciform, or polycyclic with an ecchymotic center. Urticaria multiforme is described in children aged from 4 months to 4 years, rarely in adolescents. As far as we know, this is the 4th case reported in the literature.
ABSTRACT
Urticaria is a disease characterized by wheals and/or angioedema. Chronic spontaneous urticaria (CSU) occurs for longer than 6 weeks and appears independently of any identifiable exogenous stimulus. During the vaccination campaign for Coronavirus disease 2019 (COVID-19) pandemic, several cutaneous adverse events have been described, among which urticaria lasting less than 6 weeks (acute urticaria, AU). AU due to vaccines can be IgE or non-IgE mediated; the former typically develop within 4 h of drug exposure, the latter occurs later and the mechanism is unclear. In this retrospective study we analyzed the frequency and clinical characteristics of urticaria occurring after COVID-19 vaccine (post-vaccination urticaria relapse) in adult CSU patients treated with antihistamine and omalizumab, and in clinical remission.

Introduction: Coronavirus disease 2019 (COVID-19) has caused thousands of deaths since it was declared as a pandemic. Recently it continues to be one of the most followed topics in the world in terms of its course and treatment. Favipiravir is a broad-spectrum anti-viral agent that has been shown to be effective against various Coronaviruses in vitro. However, as with any drug use, side effects may develop with the use of favipravir treatment. Case Report: We reported a 55-year-old female patient with acute urticarial with angioedema whom had COVID-19 pneumonia. She had no history of allergy, atopy, previous similar episodes or family history of hereditary angioedema. There is no drug or food consumption that may be suspicious in terms of allergy described by the patient other than favipravir. Conclusion: As far as we know, it is the first case reported from our country. Since there is no specific examination for differential diagnosis, we cannot distinguish as a rare side effect due to favipiravir treatment or COVID-19 cutaneous manifestation. As a result, studies involving more cases of COVID-19 skin findings are needed.
ABSTRACT
The clinical data of 19 cases with acute urticaria after vaccination of COVID-19 vaccine (vero cell), (Beijing Institute of Biological Products Co, Ltd) were retrospectively analyzed in our hospital from January 2021 to June 2021. Of 19 patients, 8 were males and 11 were females, aged from 18 to 60 years old. One patient presented with wheals, laryngeal edema, with slight suffocation after 1h of vaccination, and 18 patients presented with wheals and itching after 24h of vaccination. All 19 patients were cured after treatment. © 2022 The authors. All right reserved.
ABSTRACT
The COVID-19 pandemic is the most serious health crisis facing the modern world; hospital admissions have risen dramatically. Urticaria is characterized by itchy edematous papules/plaques, angioedema, and involvement of one or both of the deep dermis or subcutis. We investigated the effect of the COVID-19 pandemic on the incidence of acute and chronic urticaria, the proportions of urticaria patients among all dermatology patients before and after the onset of the pandemic, and age and sex characteristics. About 57 patients diagnosed with urticaria before the onset of the COVID-19 pandemic in December 2019 and January and February 2020 at the Dermatology Polyclinic of Beysehir State Hospital, and 25 patients diagnosed within 3 months (March-May 2020) after the onset of the pandemic, were included. We retrospectively recorded age, sex, and the duration of the disease. Patients were divided into those with acute and chronic urticaria using the EAACI/GA(2)/LEN/EDF/WAO guidelines and data obtained before and after the onset of the pandemic were compared. Fifty-one (62.2%) patients were female and the mean patient age was 40.88 ± 17.38 years. We found no significant difference in the mean age or sex distribution before and after the onset of the pandemic (P = .341; P = .604). The proportion of urticaria patients (1.6%) among all dermatology patients treated in a 3-month period after the onset of the pandemic was higher than that before the pandemic (1.19%; P < .001). During the pandemic, the acute urticaria rate was significantly higher than before the pandemic (P = .002). The urticaria rate (particularly that of acute disease) increased during the COVID-19 pandemic. Dermatologists should consider whether patients with urticaria might be infected with COVID-19.
