RESUMO

Background: Compared with advances in a drug hypersensitivity diagnosis and management, little is known about the mental health status of patients with drug hypersensitivity and the impact of this psychological distress on their quality of life (QoL). Objective: The objectives were to evaluate anxiety, depression, and QoL levels in patients with drug hypersensitivity, assess how some related factors may affect them, and determine the impact of disease on their QoL. Methods: A total of 203 patients with drug hypersensitivity and 80 healthy controls were evaluated with the Beck Anxiety (BAI) and the Depression Inventory (BDI), and the short version of the World Health Organization Quality of Life (WHOQOL-BREF) scale. Results: The mean ± standard deviation (SD) BAI scores of the patients and the controls were 13.46 ± 11.78 and 1.94 ± 1.93, respectively (p < 0.0001). The mean ± SD BDI scores were higher in the patient group (9.23 ± 6.36) than in the control group (2.18 ± 2.02) (p < 0.0001). The patients had significantly increased risk of anxiety versus the controls (48.8% versus 7.5%) (odds ratio [OR] 11.74 [95% confidence {CI}, 4.88-28.20]; p < 0.0001) and depression versus the controls (31.5% versus 6.2%) (OR 6.90 [95% CI, 2.66-17.90]; p = 0.0001). The comparison of patients' BAI and BDI scores showed that those with more severe reactions had higher scores than those with moderate and mild reactions. A negative correlation was found among all WHOQOL-BREF scale domain scores and the BAI and BDI scores. Conclusion: Anxiety and depressive symptoms have a high prevalence in patients with confirmed drug hypersensitivity, which leads to a notable decrease in QoL. Self-administered psychological questionnaires were shown to be useful in the psychological examination and management of patients with drug hypersensitivity. Therefore, we found that psychological support is critical to reducing the negative outcomes of hypersensitivity reactions in patients.

RESUMO

BACKGROUND: Drug hypersensitivity reaction (DHR) is a common reason for an allergology con- sultation, during which it is not only necessary to gather a thorough medical history, but also to propose and perform diagnostic tests. OBJECTIVES: The aim of the study was to retrospectively assess the patients with a profile of preliminary drug hypersensitivity diagnosis, the usefulness of NSAID hypersensitivity classifica- tion in outpatient practice, and to analyze the results of skin, provocation, and drug tolerance tests performed in Immunology and Allergy Clinic patients. METHODS: Around 501 medical records of patients referred to the academic allergy outpatient clinic from 2011 to 2019, and had a preliminary drug hypersensitivity diagnosis were analyzed. The diagnostic and drug tolerance tests results carried out in 269 patients of the Clinic from 2009 to 2019 were then evaluated. RESULTS: Among the patients referred due to suspected drug hypersensitivity, the majority (n=338, 67.5%) were believed to be hypersensitive to NSAIDs and antibiotics (n=272, 54.3%). In patients with hypersensitivity to NSAIDs, the mixed pattern was the most prevalent (n=73, 21.6%), followed by NECD (n=64, 18.9%) and NIUA (n=55, 16.3%). The second most common drug causing DHR were the antibiotics, mainly ß-lactams (n=160, 58.8%), followed by macrolides (n=35, 12.9%). In hypersensitivity caused due to ß-lactams, the delayed form was predominant (n=24, 15%) with manifested skin symptoms (n=74, 46.3%). Non-steroidal anti-inflammatory drugs (n=21, 42.9%), followed by antibiotics (n=11, 22.5%) were the commonest causes of ana- phylaxis, as reported by 49 patients. CONCLUSION: The study shows that a majority of patients with suspected drug hypersensitivity can be classified under the hypersensitivity umbrella based on their medical history, which is the basis for further diagnostic process.

RESUMO

Drug allergies are reported in approximately 10% of children and carry significant health and economic impacts. However, only a minority of these reported drug allergies are established on diagnostic workup. Classically, drug allergies were diagnosed by skin prick and/or intradermal tests. However, recent data reveal that a direct ingestion challenge is often an appropriate diagnostic strategy in cases of reported nonsevere reactions to penicillin derivatives in children. This article will review the prevalence, diagnosis, and management of the main culprits of pediatric drug allergies: antibiotics and nonsteroidal anti-inflammatory drugs (NSAIDs). We will also review severe cutaneous adverse reactions to drugs in children.

RESUMO

Electronic health records (EHRs) have revolutionized the field of drug hypersensitivity reaction (DHR) research. In this systematic review, we assessed 140 articles from 2000-2021, classifying them under six themes: observational studies (n=61), clinical documentation (n=27), case management (n=22), clinical decision support (CDS) (n=18), case identification (n=9), and genetic studies (n=3). EHRs provide convenient access to millions of medical records, facilitating epidemiological studies of DHRs. Though the goal of CDS is to promote safe drug prescribing, allergy alerts must be designed and used in a way that supports this effort. Ultimately, accurate allergy documentation is essential for DHR prevention.

RESUMO

BACKGROUND: Approximately 2% of patients in primary care practice and up to 25% of hospital patients are registered as being allergic to an antibiotic. However, up to 90% of these registrations are incorrect, leading to unnecessary prescription of 2nd choice antibiotics with the attendant loss of efficacy, increased toxicity and antibiotic resistance. To improve registration, a better understanding is needed of how incorrect labels are attributed. OBJECTIVE: To investigate the quality of antibiotic allergy registration in primary care and identify determinants to improve registration of antibiotic allergies. DESIGN: Registration of antibiotic allergies in primary care practices were analysed for 1) completeness and 2) correctness. To identify determinants for improvement, semi-structured interviews with healthcare providers from four healthcare domains were conducted. PARTICIPANTS: A total of 300 antibiotic allergy registrations were analysed for completeness and correctness. Thirty-four healthcare providers were interviewed. MAIN MEASURES: A registration was defined as complete when it included a description of all symptoms, time to onset of symptoms and the duration of symptoms. It was defined as correct when the conclusion was concordant with the Salden criteria. Determinants of correct antibiotic allergy registrations were divided into facilitators or obstructers. KEY RESULTS: Rates of completeness and correctness of registrations were 0% and 29.3%, respectively. The main perceived barriers for correct antibiotic allergy registration were insufficient knowledge, lack of priority, limitations of registration features in electronic medical records (EMR), fear of medical liability and patients interpreting side-effects as allergies. CONCLUSIONS: The quality of antibiotic allergy registrations can be improved. Potential interventions include raising awareness of the consequences of incomplete and the importance of correct registrations, by continued education, and above all simplifying registration in an EMR by adequate ICT support.

RESUMO

Importance: Penicillin allergy labels influence clinical decision-making, yet most children who are labeled do not have type 1 hypersensitivity allergic reactions and instead have a history of predictable adverse reactions or unspecified illness symptoms while receiving penicillin for viral infections. Studies describing penicillin allergy labeling in the pediatric outpatient setting are lacking. Objective: To describe the epidemiology and factors associated with penicillin allergy labels across 2 large US pediatric primary care networks. Design, Setting, and Participants: This retrospective, longitudinal birth cohort study was conducted in 90 primary care pediatric practices serving a diverse population of children across Houston, Texas, Austin, Texas, Philadelphia, Pennsylvania, and parts of New Jersey. Participants were children born between January 2010 and June 2020 who had a health care visit in the first 14 days of life and at least 2 additional visits in the first year of life at one of 90 primary care pediatric practices. Censoring criteria were additionally applied to exclude data from children no longer seeking health care in the 90 clinics over time. Statistical analysis was performed from February to May 2021. Exposures: Basic patient demographics, health care utilization, penicillin exposure, and primary clinic location. Main Outcomes and Measures: Addition of penicillin allergy label in the electronic medical record. Results: Among 334 465 children in the birth cohort, 164 173 (49.1%) were female; 72 831 (21.8%) were Hispanic, 59 598 (17.8%) were non-Hispanic Black, and 148 534 (44.4%) were non-Hispanic White; the median (IQR) age at censoring was 3.8 (1.7-6.6) years; 18 015 (5.4%) were labeled as penicillin allergic, but the prevalence of penicillin allergy labeling ranged from 0.9% to 10.2% across practices. Children were labeled at a median (IQR) age of 1.3 (0.9-2.3) years. Non-Hispanic White children were more likely to be labeled compared with non-Hispanic Black children after controlling for potential confounders (adjusted odds ratio, 1.7 [95% CI, 1.6-1.8]). There were 6797 allergic children (37.7%) labeled after receiving 1 penicillin prescription and 1423 (7.9%) labeled after receiving 0 penicillin prescriptions. Conclusions and Relevance: In this cohort study of more than 330 000 children, penicillin allergy labeling was common and varied widely across practices. Children were labeled early in life, and almost half were labeled after receiving 1 or 0 penicillin prescriptions. These findings raise questions regarding the validity of penicillin allergy labels. Future work exploring the fidelity of and outcomes associated with penicillin allergy-labeling in children is warranted.

RESUMO

Background: Penicillin is the most common reported drug allergy. Previous literature suggests that there is increased prevalence of penicillin drug allergy in female patients in the outpatient setting. However, this is poorly described in the inpatient setting. Objective: This study was performed to determine whether female sex is an independent risk factor for penicillin allergy in the inpatient setting. Methods: A retrospective review of electronic medical records (January 1, 2001-December 31, 2017) was performed for patients with a history of penicillin allergy who underwent penicillin skin testing (PST). Each chart review included the age at initial skin testing, sex, medications, and medical co-morbidities. The study was approved by the institutional review board. Results: 30,883 patients underwent PST with 29,354 and 1,529 occurring in the outpatient and inpatient setting respectively. 170 patients tested positive with a ≥ 5x5 wheal. Of the 170 positive patients, 122 were female (72%) and 48 were male (28%). 15 patients tested positive in the inpatient setting. Of the 1506 adult patients tested in the inpatient setting, 809 were female and 697 were male. 12 females (92.3%) and 1 one male (7.7%) tested positive with a ≥ 5x5 wheal (OR-10.5; 95% CI-1.4-80.8; p-value=0.02). 23 pediatric patients were tested in the inpatient setting. Two pediatric male patients were positive and no female pediatric patients tested positive (OR-1.7; 95% CI-0.5-5.9; p-value=0.5). Conclusion: In the inpatient setting, adult females are 10 times more likely to have a positive PST compared to males. Female sex may be a potential risk factor for objective penicillin drug allergy in the inpatient setting.

RESUMO

Since overdiagnosis of beta-lactam (BL) allergy is common in the pediatric population, delabeling is a critical part of antimicrobial stewardship. Undesirable consequences of inaccurate BL allergy labeling can be handled by incorporating traditional delabeling or newer risk-based strategies into antibiotic stewardship programs. Conventional assessment of BL allergy relies upon a stepwise algorithm including a clinical history with skin testing followed by drug provocation tests (DPTs). However, a growing number of studies highlighted the suboptimal diagnostic value of skin testing in children. Recently, there has been a paradigm shift in the practice of BL allergy assessment due to recent challenging data which emphasize the safety and accuracy of direct DPTs in children with a suspicion of non-immediate mild cutaneous reactions such as maculopapular eruption, delayed urticaria, and possibly also for benign immediate reactions such as urticaria/angioedema. Identifying low-risk BL allergy patients, in whom skin tests can be skipped and proceeding directly to DPTs could be safe, has become a hot topic in recent years. New risk stratification and predictive modeling studies that have the potential to better predict BL allergy risk status have recently been introduced into the field of drug allergy, particularly in adults. However, in contrast to adults, risk assessment studies in children are rare, and optimal risk definitions are controversial. In the coming years, promising potential methods to elucidate the predictors of BL allergy in children will require multidimensional approaches that may include predictive analytics, artificial intelligence techniques, and point-of-care clinical decision tools.

RESUMO

Background With the widespread use of gadolinium-based contrast agents (GBCAs), the incidence of allergic-like hypersensitivity reactions (HSRs) to GBCAs is increasing. Research on the incidence and risk factors for HSRs to GBCAs is needed for their safe use. Purpose To determine the incidence of acute and delayed reactions to GBCAs and to discuss the risk factors and strategies for the prevention of HSRs to GBCAs. Materials and Methods All cases of HSRs to contrast media that occurred at the Seoul National University Hospital from July 1, 2012, to June 30, 2020, were assessed. Information including age, sex, GBCA type, onset, and severity of HSRs was retrospectively analyzed. Results Among the 331070 cases of GBCA exposure in 154539 patients, 1304 cases of HSRs (0.4%) were reported. Acute HSRs accounted for 1178 cases (0.4%), while 126 cases (0.04%) were delayed HSRs. While both premedication (odds ratio [OR] = 0.7, P = .041) and changing the type of GBCA (OR = 0.2, P < .001) showed preventative effects in patients with a history of acute HSRs, only premedication (OR = 0.2, P = .016) significantly reduced the incidence of HSRs in patients with a history of delayed reactions. The risk of an HSR to GBCA was higher in those with a history of an HSR to iodinated contrast media (OR = 4.6, P < .001). Conclusion The rate of hypersensitivity reactions (HSRs) to gadolinium-based contrast agents (GBCAs) was 0.4%. The absence of premedication, repeated exposures to the culprit GBCA, and a history of HSRs to iodinated contrast media and GBCAs were risk factors for HSRs to GBCAs. © RSNA, 2022 Online supplemental material is available for this article.

RESUMO

SUMMARY: Background. The literature describes several risk factors for hypersensitivity (HS) reactions to iodinated contrast media (ICM). Objective. To analyze the characteristics of patients experiencing HS reactions to ICM with a focus on oncological status. Methods. All patients (n = 80) with suspected HS to ICM who underwent an allergy evaluation in a Belgian University Hospital over a 5-year period were retrospectively included. Results. Overall, forty patients (50%) had a history of neoplasia, and this group was characterized by less atopy (p less than 0.004). No significant difference was observed between oncological and non-oncological patients in terms of gender, age, cardiovascular diseases, medical treatment, and number of previous exposures or reactions to ICM. Conclusions. A high proportion of oncological patients was observed in our population with HS to ICM. They did not have other known risk factors, and they were less atopic. Larger multicentric studies should explore cancer as a potential new risk factor.

RESUMO

OBJECTIVE: We aimed to determine the risk factors of perioperative drug hypersensitivity reaction (DHR) and develop a predictive score for use in clinical practice. METHODS: A case-control study was conducted in patients who underwent anesthesia at a tertiary hospital in Thailand, between 2015-2018. DHR cases were graded clinically from 1 to 4 according to the World Federation of Societies of Anesthesiologists by two anesthesiologists. Controls were randomly matched with cases (ratio 2:1) by age group and month and type of surgery. Patient and anesthesia-related factors and agents given intraoperatively were recorded. A risk score was derived from the coefficients of the significant predictors of the final multivariate logistic regression model. Risk scores, adjusted odds ratios (OR) for perioperative DHR and 95% confidence intervals (CI) were determined. RESULTS: Overall, 325 cases and 650 controls were recruited. The severity of DHR was grade 1 (72.9%), grade 2 (24%), and grade 3 (3.1%). Our risk predictive tools for perioperative DHR provided a sensitivity of 62% and specificity of 65%. Predictive scores of subgroups of moderate to severe DHR showed high specificity (80%) but low sensitivity (47%). Common predictors of overall DHR and moderate to severe DHR were history of drug allergy to 2 or more drug categories (score 2.5-3.5), being allergic to analgesics (score 2.5-4.0), and intraoperative morphine use (score of 1). The sole predictor of high-risk perioperative DHR (score ≥3.5) was airway management with an endotracheal tube intubation (OR 5.6, 95% CI 2.2-14.4) whereas history of allergic rhinitis (OR 11.7, 95% CI 1.3-105.1) was a predictor of high-risk moderate to severe DHR (score ≥2.5). CONCLUSIONS: Our predictive tool for perioperative DHR provided a modest predictive ability. History of drug allergies, rhinitis, morphine use and endotracheal intubation were significant risk factors of DHR after adjusting for age and type of surgery.

RESUMO

BACKGROUND: Atopic dermatitis (AD) is a heterogeneous disease with different age of onset, disease course, clinical symptoms, severity, and risk of comorbidity. The characteristics of children with AD also vary by age or country. However, little is known about the clinical characteristics of AD in Korean school-aged children and adolescents. Furthermore, there are few studies on phenotypic differences according to onset age. This study aimed to explore the clinical characteristics and phenotypes according to onset age and severity of AD in children and adolescents in Korea. METHODS: AD patients aged 6-18 years who presented to 18 hospitals nationwide were surveyed. The patients were examined for disease severity by pediatric allergy specialists, and data on history of other allergic diseases, familial allergy history, onset age, trigger factors, lesion sites, treatment history and quality of life were collected. The results of the patient's allergy test were also analyzed. The patients were classified into infancy-onset (< 2 years of age), preschool-onset (2-5 years of age), and childhood-onset (≥ 6 years of age) groups. Study population was analyzed for clinical features according to onset-age groups and severity groups. RESULTS: A total of 258 patients with a mean age of 10.62 ± 3.18 years were included in the study. Infancy-onset group accounted for about 60% of all patients and presented significantly more other allergic diseases, such as allergic rhinitis and asthma (P = 0.002 and P = 0.001, respectively). Food allergy symptoms and diagnoses were highly relevant to both earlier onset and more severe group. Inhalant allergen sensitization was significantly associated with both infancy-onset group and severe group (P = 0.012 and P = 0.024, respectively). A family history of food allergies was significantly associated with infancy-onset group (P = 0.036). Severe group was significantly associated with a family history of AD, especially a paternal history of AD (P = 0.048 and P = 0.004, respectively). Facial (periorbital, ear, and cheek) lesions, periauricular fissures, hand/foot eczema, and xerosis were associated with infancy-onset group. The earlier the onset of AD, the poorer the quality of life (P = 0.038). Systemic immunosuppressants were used in only 9.6% of the patients in the severe group. CONCLUSION: This study analyzed the clinical features of AD in Korean children and adolescents through a multicenter nationwide study and demonstrated the phenotypic differences according to onset age and severity. Considering the findings that the early-onset group is more severe and accompanied by more systemic allergic diseases, early management should be emphasized in young children and infants.

RESUMO

BACKGROUND/AIM: Carboplatin is a key drug in the treatment of ovarian cancer, but hypersensitivity reactions (HSRs) may occur with repeated use. PATIENTS AND METHODS: Thirty-seven ovarian cancer patients treated with carboplatin desensitization therapy were reviewed retrospectively. The treatment completion rate and toxicity were examined. RESULTS: The carboplatin desensitization completion rate was 86.5%. Toxicity was Grade 0, 1, 2, and 3 in 17, 5, 10, and 5 patients, respectively. Erythema was the most frequent toxicity (36.8%), most commonly affecting the arm (23.5%). Furthermore, all HSRs were classified into: skin, respiratory, digestive, circulatory, and neurological. The completion rate of desensitization was significantly lower in patients with two or more target organs affected (p<0.001). CONCLUSION: The main symptoms of HSRs, the most common sites of HSRs, and the criteria for discontinuing desensitization therapy identified in this study are useful information for the safe implementation of carboplatin desensitization therapy.

RESUMO

Betalactams are the most widely used antimicrobials for their safety and efficacy. These include the penicillins, cephalosporins, carbapenems, and monobactams. Penicillin allergy ranks first in relation to drug allergy. 10 to 20 % of the population is labeled as allergic to it, often wrongly. Cross reaction is reported in 2 to 5 % between penicillins and cephalosporin. There is no cross reaction between penicillins and aztreonam, but there is with ceftazidime. All the mechanisms of the Gell and Coombs classification are included in the pathophysiology of hypersensitivity reactions to penicillin. Stratification according to risk allows us to take the most objective behavior to label the patient as allergic to. In the natural history of penicillin allergy, 80-90 % of patients lose this sensitivity by 10 years. If necessary, the patient can undergo a desensitization protocol. The immuno-allergist is a key piece in the selection of the patient, the elaboration of the challenge and desensitization protocols, in a controlled environment.


Los betalactámicos son los antimicrobianos más utilizados por su seguridad y eficacia. En este grupo se incluyen las penicilinas, las cefalosporinas, los carbapenémicos y los monobactámicos. La penicilina constituye la primera causa de alergia a medicamentos: 10 a 20 % de la población se etiqueta como alérgica a la misma, en muchas ocasiones erróneamente. Se ha reportado reacción cruzada entre penicilinas y cefalosporina en 2 a 5 %. No hay reacción cruzada entre penicilinas y aztreonam, pero sí con ceftazidima. En la fisiopatología de las reacciones de hipersensibilidad a penicilina se incluyen todos los mecanismos de la clasificación de Gell y Coombs. La estratificación de acuerdo con el riesgo permite tomar la decisión más objetiva para etiquetar al paciente como alérgico. En la evolución natural de la alergia a la penicilina, 80 a 90 % de los pacientes pierde dicha sensibilidad a los 10 años. De ser indispensable, el paciente puede ser sometido a un protocolo de desensibilización. El médico inmunoalergologo es una pieza clave en la selección del paciente, la elaboración de los protocolos de reto y la desensibilización en un ambiente controlado.

RESUMO

Chemotherapeutic drugs have been widely used in the treatment of cancer disease for about 70 years. The development of new treatments has not hindered their use, and oncologists still prescribe them routinely, alone or in combination with other antineoplastic agents. However, all chemotherapeutic agents can induce hypersensitivity reactions (HSRs), with different incidences depending on the culprit drug. These reactions are the third leading cause of fatal drug-induced anaphylaxis in the United States. In Europe, deaths related to chemotherapy have also been reported. In particular, most reactions are caused by platinum compounds, taxanes, epipodophyllotoxins and asparaginase. Despite their prevalence and relevance, the ideal pathways for diagnosis, treatment and prevention of these reactions are still unclear, and practice remains considerably heterogeneous with vast differences from center to center. Thus, the European Network on Drug Allergy and Drug Allergy Interest Group of the European Academy of Allergy and Clinical Immunology organized a task force to provide data and recommendations regarding the allergological work-up in this field of drug hypersensitivity reactions. This position paper aims to provide consensus on the investigation of HSRs to chemotherapeutic drugs and give practical recommendations for clinicians that treat these patients, such as oncologists, allergologists and internists. Key sections cover risk factors, pathogenesis, symptoms, the role of skin tests, in vitro tests, indications and contraindications of drug provocation tests and desensitization of neoplastic patients with allergic reactions to chemotherapeutic drugs. Statements, recommendations and unmet needs were discussed and proposed at the end of each section.

RESUMO

Penicillin allergies are reported by 8% to 15% of the US population, but up to 95% of these allergies do not correspond to a true allergy when tested. Recent studies have demonstrated that having a penicillin allergy label (PAL) results in a 50% increased odds of surgical site infection among patients reporting a penicillin allergy entirely attributable to the use of a beta-lactam alternative antibiotic (primarily clindamycin or vancomycin). This study provides a review of the prevalence of PAL, the cross-reactivity with cefazolin, immunogenic components of cefazolin and penicillin, and current guidelines for preoperative antibiotic selection in patients with PALs. On understanding these principles, a new set of guidelines and a risk stratification tool are proposed for assessing allergies and determining appropriate antibiotic choice, dosage, and timing in the orthopaedic preoperative setting.

RESUMO

PURPOSE: The aim of this study was to analyze the risk of hypersensitivity reactions (HSRs) to iopromide in children and elderly patients in comparison to adults. MATERIALS AND METHODS: Four observational studies were pooled and analyzed (analysis I). In addition, spontaneous reports from 1985 to 2020 from the pharmacovigilance database were evaluated (analysis II). All patients received iopromide for angiographic procedures or contrast-enhanced computed tomography in various indications. In analysis I, a nested case-control analysis, including a multivariable logistic regression model, based on pooled observational study data, was performed. Cases were defined as patients with a typical and unequivocal HSR; controls were patients without any recorded reaction. In analysis II, all spontaneous reports on HSRs after iopromide administration recorded in the pharmacovigilance database were descriptively analyzed. Exposure estimates on the size of the exposed age groups were derived from sales data and data from market research. The primary target variable was the risk of HSR to iopromide in children (<18 years) and elderly patients (≥65 years) compared with adults (≥18 to <65 years). RESULTS: In analysis I, a total of 132,850 patients were included (2978 children, 43,209 elderly, and 86,663 adults). Hypersensitivity reactions were significantly less frequent in children (0.47%) and elderly (0.38%) compared with adults (0.74%). The adjusted odds ratio (vs adults) for children was 0.58 (95% confidence interval, 0.34-0.98; P < 0.043), and that for the elderly was 0.51 (95% confidence interval, 0.43-0.61; P < 0.001), indicating a lower risk for both subpopulations as compared with adults. In analysis II, of the overall >288 million iopromide administrations, 5.87, 114.18, and 167.97 million administrations were administered to children, elderly, and adults, respectively. The reporting rate for HSRs in children (0.0114%) and elderly (0.0071%) was significantly lower as compared with adults (0.0143%) (P < 0.0001). CONCLUSIONS: Hypersensitivity reactions to iopromide were significantly less frequent in children and elderly compared with adults.

RESUMO

BACKGROUND: Patient-reported allergies to aspirin or nonsteroidal anti-inflammatory drugs (NSAIDs) may preclude certain patients from receiving aspirin as venous thromboembolism (VTE) prophylaxis after total joint arthroplasty (TJA). The purpose of the study was to (1) determine whether the use of non-aspirin agents due to a self-reported aspirin or NSAID allergy was associated with a higher incidence of VTE and (2) determine the rate of true allergic reactions in patients who reported an allergy but still received aspirin. METHODS: Prospectively collected data from 45,171 patients who underwent primary TJA between 2000 and 2019 were reviewed. Patients who reported an allergy to aspirin or NSAIDs were identified (n = 823). Using a validated VTE risk calculator, each patient was assigned a risk score based on 26 comorbidities. Bleeding complications, VTEs that occurred within 90 days postoperatively, and allergic reactions were collected as end points. Multivariable logistic regression was performed to determine the factors associated with VTE. RESULTS: The overall incidence of aspirin or NSAID allergy was 1.8%. Only 80 of 267 patients (30%) reported an allergy to only aspirin and still received aspirin. Compared with patients who received aspirin without a history of allergy (n = 17,648), patients who received non-aspirin thromboprophylaxis due to allergy (n = 383) had a higher incidence of VTE (2.87% versus 0.24%, p < 0.001). On multivariable regression, these patients had an 8-fold increase in VTE risk (adjusted odds ratio, 7.94; 95% confidence interval, 2.86 to 22.07; p < 0.001). The incidence of true allergic reactions to aspirin among those with a reported allergy was 1.8% (number needed to harm = 55). No patients developed anaphylaxis or severe hypersensitivity reactions. CONCLUSIONS: Patients with a self-reported allergy to aspirin or NSAIDs were at a significantly increased risk for VTE if they received non-aspirin thromboprophylaxis agents following TJA. Future research should evaluate the usefulness of preoperative allergy testing when selecting a VTE prophylactic agent in patients with self-reported allergies. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
