Abstract
BACKGROUND In case of suspected hypersensitivity reactions (HRs) to drugs, a challenging area for pediatricians is detecting relevant elements in the parent-reported history, in order to reach a definite diagnosis. We analyzed the concordance between the description of the HR and the medical reports documented at the time of the event. Furthermore, we studied any correlation between clinical history variables and the prediction of true allergy. METHODS We retrospectively collected 50 charts of children referred to our Allergy Unit, after a previous access to the Emergency Department. We compared the description of the HR at acute phase to the history told by parents. Type and timing of the HR and culprit drug were classified as "known" or "unknown." The diagnosis was confirmed or excluded at the end of the investigations. Logistic regression analysis was performed to find any significant association. RESULTS The type of the HR was known in 74%, the timing in 28%, and the culprit drug in 98%. We showed that having had a severe HR had an increased odds of remembering the timing; being older >6 years and having had an immediate HR had an increased odds of remembering the type; time to diagnostic was lower in patients whose parents remembered the type of HR. CONCLUSION Our paper underlines the importance of an accurate anamnesis at the time of the event. Providing the physicians with a standardized Case Report Form could be a useful tool to simplify the diagnostic work-up and minimize mistakes due to lack of memory.

Abstract
Drug hypersensitivity reactions (DHR) in children have a significant impact on clinical practice and public health. Both under-diagnosis (due to under-reporting) and over-diagnosis (due to the overuse of the term "allergy") are potential issues. The aim of this narrative review is to describe the most recent findings of DHR in children/adolescents and gaps regarding epidemiology, antibiotic allergy, antiepileptic hypersensitivity, vaccine allergy, and severe cutaneous adverse reactions (SCAR) in this age group.

Abstract
BACKGROUND AND OBJECTIVES Penicillin allergy labels are the most common drug allergy label. The objective of this study was to describe the quality and management of penicillin allergy labels in the pediatric primary care setting. METHODS Retrospective chart review of 500 of 18 015 children with penicillin allergy labels born from January 1, 2010 to June 30, 2020 randomly selected from an outpatient birth cohort from Texas Children's Pediatrics and Children's Hospital of Philadelphia networks. Penicillin allergy risk classification ("not allergy," "low risk," "moderate or high risk," "severe risk," "unable to classify") was determined based on documentation within (1) the allergy tab and (2) electronic healthcare notes. Outcomes of allergy referrals and penicillin re-exposure were noted. RESULTS Half of penicillin allergy labels were "unable to classify" based on allergy tab documentation. Risk classification agreement between allergy tabs and healthcare notes was fair (Cohen's ĸ = 0.35 ± 0.02). Primary care physicians referred 84 of 500 (16.8%) children to an allergist, but only 54 (10.8%) were seen in allergy clinic. All children who were challenged (25 of 25) passed skin testing. Removal of allergy labels was uncommon (69 of 500, 13.8%) but occurred more often following allergy appointments (26 of 54, 48%) than not (43 of 446, 9.6%, P < .001). Children delabeled by primary care physicians were as likely to tolerate subsequent penicillin-class antibiotics as those delabeled by an allergist (94% vs 93%, P = .87). CONCLUSIONS Penicillin allergy documentation within the allergy tab was uninformative, and children were infrequently referred to allergists. Future quality improvement studies should improve penicillin allergy documentation and expand access to allergy services.

Abstract
AIMS To determine the frequency of an authentic β-lactam (BL) hypersensitivity (HS) amongst a large number of children and to identify clinical risk factors that predict this hypersensitivity. METHODS All children with suspected BL allergy were evaluated by skin tests (ST) with the suspected BL. A 1-day oral provocation test (OPT) was performed in children with negative ST. We defined an authentic BL-HS case if the child exhibited a positive ST or a positive OPT. Risk factors associated with BL-HS were assessed using a univariate analysis. Covariates showing a P-value <.2 were included in the multivariate logistic regression analysis to determine independent predictors. RESULTS A total of 354 patients reporting 368 suspected BL reactions were included. The diagnosis of BL-HS was established in 24 children (6.7%). All these children had a positive ST. OPT was performed in 30 patients and was negative in all of them. In 110 children with a negative ST, BL was tolerated. In the risk factors analysis, 164 children were included. Older age (>5 years) at the reaction (odds ratio = 1.11; 95% confidence interval, 1.01-1.22; P = .02) and BL administered (odds ratio = 7.7; 95% confidence interval, 2.76-21.8; P < .001) were significantly associated with authentic BL-HS. CONCLUSION BL-HS should be evaluated with an appropriate allergy work-up before strict prohibition is made. In addition, age of patient and BL involved can be used as predictive factors of developing BL-HS in this population.

THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY. IN PRACTICE 2022; 10:2958-2966.e3. [PMID: 35872215 DOI: 10.1016/j.jaip.2022.06.048] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/04/2022] [Revised: 05/26/2022] [Accepted: 06/20/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Amoxicillin-associated reactions (AARs) contribute to substantial health care utilization, with a reutilization rate of 10% in pediatric emergency department (ED) and urgent care (UC) settings. OBJECTIVE To identify predictors of ED/UC reutilization by examining patients' clinical features and providers' management of AARs. METHODS Through a retrospective chart review of 668 patients presenting with AARs over 2 years to the pediatric ED/UC, we examined clinical features associated with ED/UC reutilization, including rash phenotype, systemic symptoms (fever, angioedema, joint involvement, gastrointestinal symptoms), and providers' management (pharmacologic treatment and counseling). We then constructed a statistical model to predict ED/UC reutilization using stepwise backward model selection. RESULTS ED/UC reutilizers were more likely to be male (P = .008) and have fever (P = .0001), angioedema (P < .0001), joint involvement (P < .0001), and gastrointestinal symptoms (P = .0001) during their AAR course. Rash phenotypes differed between groups (P < .0001), as ED/UC reutilizers more frequently exhibited urticaria. However, there were no differences in clinical management between groups, including pharmacologic recommendations, at the initial ED/UC encounter. In addition, our statistical model identified younger patients <2 years of age as more likely to reutilize ED/UC resources if providers did not document specific return precautions (odds ratio, 3.6; 95% confidence interval, 1.7-7.7). CONCLUSION Recognition of clinical features and treatment gaps associated with ED/UC reutilization will guide interventions to optimize care in children presenting with AARs, such as improved anticipatory guidance and early allergy consultation. Prospective studies are needed to determine whether these interventions will reduce ED/UC reutilization and facilitate timely allergy testing.

Abstract
AIM The main objective of this study was to see how many of the children, with a suspected antibiotic allergy, developed an allergic or adverse reaction to a drug provocation test. METHODS Data on children that had undergone a drug provocation test for a suspected antibiotic allergy were compiled retrospectively for the period from 2007-2018. The median age at the first provocation was 2.25 years (1.5-5.7). Standardised questionnaires, the children's parents had answered before the provocation, were used to evaluate the originally suspected allergic reaction, previous health, atopic diseases and family history. RESULTS Ninety-two (6.4%) of the 1440 children showed a possible mild allergic reaction. Sixty-four of the 92 children underwent a second drug provocation test 1-2 years later. At that time, only eleven developed a positive- or a possible-delayed reaction. CONCLUSION An immediate moderate or severe allergic reaction was excluded in all cases of suspected antibiotic allergy in this study. Our study indicates that an oral drug provocation test is safe. It may be appropriate to wait for 6 months or more after the initial event of ADR before these tests are performed. A second oral provocation 1-2 years after the first one shows that ADRs are outgrown in most children.

Abstract
BACKGROUND Distinguishing allergic reactions from non-allergic type B adverse drug reactions (ADRs) to antibiotics is challenging, particularly in children, because we lack epidemiological information that can be used in primary care situations. This study aimed to investigate the characteristics of type B ADRs to antibiotics and antibiotic allergy (AA) in previously healthy children. METHODS This was a retrospective cohort study of previously healthy children admitted for treating urinary tract infections over a 10 year period. The primary outcome was the frequency of type B ADRs and AAs that were assessed by pediatricians. Secondary outcomes include demographic data about patients' backgrounds, infections, treatments, ADRs, and action against ADRs. All the data were collected via patients' medical records. RESULTS Out of 791 participants, type B ADRs were reported in 77 children (9.7%), and AA labeling was performed in six children (0.8%). Physicians assessed 30.4% of type B ADRs as severe or life-threatening symptoms. All patients were discharged without long-term complications. Physicians detected the primary cause (individual patient host factors or environmental risks) in 39 cases of type B ADRs. CONCLUSION Type B ADRs to antibiotics were frequently reported even in previously healthy children. Physicians should use appropriate techniques (e.g., specialist consulting and skin testing) when they suspect that a type B ADR might be an AA. Labeling and de-labeling programs and tools for type B ADRs related to antibiotics should be implemented to prevent the mislabeling of AA.

Abstract
Background The lack of medication standards is a serious problem in paediatrics mainly because of age-related differences in organ development and physiological functions in children. Consequently, dosage measurement becomes inaccurate. For this reason, methods for evaluating and monitoring rational paediatric medications should be developed. Drug use indicators, such as those similar to the drug utilisation index (DUI) based on the Anatomical Therapeutic Chemical/Defined Daily Dose (DDD) and widely used for the assessment of appropriate dosage in adults, should be explored in terms of their applicability to children. Methods A total of 5,538 prescriptions of antibiotics selected from a general teaching hospital were included. Drug, dose, frequency and treatment duration were obtained from each prescription. The prescription daily dose (PDD) of each antibiotic drug was calculated as the average of the daily doses. Underdose and overdose were determined in terms of the PDD/DDD ratio for each prescription. Children’s DUI (cDUI) was explored in terms of the appropriate dosage for children as follows: the meaning of children’s DDD (cDDD) and the evaluation of paediatric drug dosage. Results The top five antibiotics and their utilisation rates were as follows: cefmetazole sodium injection (18.47 %), erythromycin lactobionate injection (15.07 %), amoxicillin/clavulanate potassium injection (10.72 %), ceftriaxone sodium injection (9.50 %) and azithromycin dry suspension (8.02 %). The ratio of cDUI and PDD/cDDD was mostly not close to 1. Conclusions The establishment of a cDUI system is an effective means of paediatric dosage evaluation. In addition to DDDs, cDUI and PDD/cDDD should be used to analyse the utilisation of antibiotics in children.

Abstract
PURPOSE OF REVIEW The true exanthematous reactions to drugs in children are rare and overdiagnosed. Drugs may cause exanthema either due to inducing an immune response or because of their interaction with viruses, if drugs are taken in the course of a viral infection. Also, viral infections are very often in children and they can provoke an exanthema which is difficult to differentiate from exanthematous reactions to drugs. Consequently, the majority of children are incorrectly labeled as 'allergic'. RECENT FINDINGS The correct diagnosis of exanthematous drug reactions in children is still an important and hot topic. Most information about the approach and management of drug hypersensitivity in children is applied from available guidelines and consensus statement for adults. Recently, a systematic clinical approach for timely differential diagnosis and management of rashes in children who present a cutaneous exanthema while receiving a drug, is proposed. SUMMARY It is important to consider the detailed clinical history of appearing and developing exanthematous drug reaction, as well as physical examination which includes the description and the distribution of exanthema and at the end making the appropriate diagnosis. Thus, it could reduce overdiagnosis and promote appropriate procedures, that will prevent the overlabeling of drug hypersensitivity in children.

Abstract
Childhood rashes or exanthemas are common and are usually relatively benign. There are many causes of rash in children, including mainly viruses, and less often bacterial toxins, drugs, allergens and other diseases. Viral exanthema often appears while children are taking a medication in the course of a viral infection; it can mimic drug exanthema and is perceived as a drug allergy in 10% of cases. In the vast majority of cases, the distinction between virus-induced and drug-induced skin eruption during the acute phase is not possible. The drugs most commonly implicated are beta-lactams (BL) and non-steroidal anti-inflammatory drugs (NSAIDs). Viruses, commonly Epstein-Barr virus (EBV), human herpesvirus 6 (HHV6) and cytomegalovirus (CMV), and the bacterium, Mycoplasma pneumoniae, may cause exanthema either from the infection itself (active or latent) or because of interaction with drugs that are taken simultaneously. Determination of the exact diagnosis requires a careful clinical history and thorough physical examination. Haematological and biochemical investigations and histology are not always helpful in differentiating between the two types of exanthema. Serological and polymerase chain reaction (PCR) assays can be helpful, although a concomitant acute infection does not exclude drug hypersensitivity. A drug provocation test (DPT) is although considered the gold standard for the diagnosis and is not preferred by the patients. Skin tests are not well tolerated, and in vitro tests, such as the basophil activation test and lymphocyte transformation, are of low sensitivity and specificity and their relevance is debatable. Based on current evidence, we propose a systematic clinical approach for timely differential diagnosis and management of rashes in children who present a cutaneous eruption while receiving a drug.

Abstract
BACKGROUND The incidence of allergy is increasing at an alarming rate for the last few decades. OBJECTIVE Our present study is focused on finding out the structurally homologous motifs present in different proteinaceous allergens Methods: Significant number of protein sequences and their corresponding structures of various pollen, fungal, bacterial, and food allergens were retrieved, and the sequence and structural identity were analyzed. RESULTS Intra- and inter-sequence and their structural analysis of the proteinaceous allergens, resulted in no significant relationships among them. A few, but not negligible number of high structural similarities were observed within different groups of allergens from fungus, angiosperms, and animals (Aves and Mammalia). CONCLUSION Our in silico study on thirty-six different allergens showed a significant level of structural similarities among themselves, regardless of their sequences.

Abstract
OBJECTIVE To examine the associations between urinary antibiotics from various sources and depression in the elderly using the biomonitoring method. METHODS In the current study, we investigated 990 elderly individuals (≥ 60 years old) from a community-based elderly cohort in West Anhui, China. The participants were interviewed by the Geriatric Depression Scale and self-developed questionnaires. A total of 45 antibiotics belonging to nine categories were screened in urine samples by the developed liquid chromatography electrospray tandem mass spectrometry method. Creatinine-corrected concentrations of antibiotics in urines were used to assess their exposure. Logistic regression analysis was employed to test the relationships between exposure to antibiotics and depression. RESULTS Compared to the control group, the multinomial logistic regression analyses showed the elderly exposed to higher concentrations of azithromycin (OR = 1.81, 95% CI: 1.09-3.00) and sulfaclozine (OR = 1.54, 95% CI: 1.05-2.28) had increased risks of depression, respectively. After categorizing the detected antibiotics, tetracyclines (OR = 1.48, 95% CI: 1.02-2.16) and veterinary antibiotics (VAs) (OR = 1.53, 95% CI: 1.06-2.20) were positively correlated with increased risks of depression. After stratified by sex, the VAs (OR = 2.04, 95% CI: 1.13-3.71) at higher concentrations were associated with elevated risks of depression in males, while the associations between depression and antibiotic exposures were observed in tetracyclines (OR = 1.74, 95% CI: 1.04-2.85) and all antibiotics (OR = 2.24, 95% CI: 1.01-2.94) at higher levels in females, respectively. Notably, after the stratification by age, the significant associations were mainly present in the subjects under the age of 70. CONCLUSIONS Our findings reveal that azithromycin, sulfaclozine, tetracyclines, and the VAs were significantly associated with elevated risks of depression in the elderly. Importantly, sex- and age-specific differences were observed in the associations between antibiotic exposures and depression.

Abstract
Up to 10% of hospitalized patients have an antibiotic allergy label in their medical file, most frequently concerning penicillins. However, the vast majority of reported allergies to antibiotics does not represent a "true" allergy but are due to drug intolerance, idiosyncratic reactions or symptoms of the concurrent infectious disease. Since antibiotic allergy labels result in deviation from first-choice antimicrobial therapy, tackling the issue of incorrect antibiotic allergy labelling, already at young age, is a core element of antibiotic stewardship. In this article, we describe the structured approach to the patient with a presumed antibiotic allergy with emphasis on key elements of allergy-specific history taking and the limited risk of cross-allergic reactions between beta-lactam subclasses.

Abstract
BACKGROUND Children are often diagnosed with an antibiotic allergy, with little investigation to confirm whether it is a true allergy. Recent studies support the use of oral challenges to confirm antibiotic allergy. Yet, little is known about families' perceptions of these challenges, or experiences of living with a misdiagnosis, often for many years. OBJECTIVE To describe how families with a child previously labelled as "antibiotic allergic," but who has subsequently been delabelled, perceive the experience of misdiagnosis and subsequent delabelling. METHODS We performed semi-structured interviews with parents whose children had recently completed a graded oral challenge for antibiotic allergy. Interview transcripts were analysed concurrently, but independently, by two investigators, using content analysis. RESULTS A total of 15 parents (14 individual interviews; 1 mother-father dyad) participated. Children were, on average, 5.04 ± 4.5 years and were first diagnosed in infancy (mean age: 1.82 ± 1.48 years) subsequent to a rash (14/14; 100%), and commonly at a walk-in clinic (6/14; 42.9%). We identified four themes: (1) A red, raised rash results in a quick diagnosis despite a lack of testing, (2) sensitive care allays concerns, (3) delabelling brings relief, but also mystery and calls for proper diagnoses, and (4) quick diagnoses are reckless, but manageable through downward comparisons. CONCLUSION AND CLINICAL RELEVANCE These findings underscore the importance of a careful physical examination and clinical history of the patient, but also an ongoing dialogue to support families, both of which would ideally begin at the time of initial investigation.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E2787. [PMID: 32316622 PMCID: PMC7215547 DOI: 10.3390/ijerph17082787] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/23/2020] [Revised: 04/11/2020] [Accepted: 04/15/2020] [Indexed: 12/19/2022]
Abstract
Anaphylaxis is most commonly defined as an acute, severe, potentially life-threatening systemic hypersensitivity reaction. Current expert consensus has defined anaphylaxis as a serious reaction that is rapid in onset and can be fatal, and is a severe, potentially life-threatening systemic hypersensitivity reaction that is still rarely diagnosed. For safety reasons, patients should visit an allergologist to identify potential causes of this reaction. There are no data from other health care centres in Poland presenting characteristics of anaphylactic reactions. Clinical manifestations of anaphylaxis should be analysed, because some patients (10-30%) with anaphylaxis can present without cutaneous findings. This lack of skin/mucosa involvement can lead to misdiagnosis or delayed diagnosis of anaphylaxis. Objectives-to gather epidemiological data on anaphylactic reactions, to identify clinical manifestations of anaphylaxis (organ systems involved), to present diagnostic methods useful for the identification of anaphylaxis triggers, and most importantly, to find causes of anaphylaxis. In this retrospective analysis, we used a questionnaire-based survey regarding patients visiting the Clinical Allergology Department, Pomeranian Medical University (PMU) in Szczecin, between 2006 and 2015. The registry comprised patients with grade II (Ring and Messmer classification) or higher anaphylaxis. Patients with grade I anaphylaxis (e.g., urticaria) were not included in the registry. The incidence of anaphylaxis was higher in women. Clinical manifestations included cutaneous and cardiovascular symptoms, but more than 20% of patients did not present with cutaneous symptoms, which may create difficulties for fast and correct diagnosis. Causes of anaphylaxis were identified and confirmed by means of detailed medical interview, skin tests (STs), and measurement of specific immunoglobulin E (sIgE) and tryptase levels. In the analysed group, the most common cause of anaphylaxis (allergic and nonallergic) was Hymenoptera stinging (wasp), drugs (nonsteroidal anti-inflammatory drugs, NSAIDs) and foods (peanuts, tree nuts, celery). The incidence of anaphylaxis is low, but because of its nature and potentially life-threatening consequences it requires a detailed approach. Comprehensive management of patients who have had anaphylaxis can be complex, so partnerships between allergy specialists, emergency medicine and primary care providers are necessary. Monitoring its range is very important to monitor changes in allergy development.

Abstract
The immune system has vital functions for homeostasis and host defense. Thus, imbalances of the immune system whether associated with allergy, hypersensitivity, or autoimmunity are of great importance, as is manifest from common diseases such as atopic diseases, urticaria, and angioedema, and drug hypersensitivity reactions. These can affect patients' quality of life and can generate high costs for health care. Epidemiological studies have provided evidence for changing patterns of allergic diseases caused by lifestyle and climate changes which have consequences for medical care. Deeper insights into the pathogenesis of allergic/immunologic diseases, combined with novel technologies, provide improved diagnostic options and treatment measures. This review will summarize novel aspects of the epidemiology, pathogenic mechanisms, as well as disease management in the fields of allergy and clinical immunology.
