Gao C, Ma B, Liu W, Zhu L. The state and consideration for skin test of β-lactam antibiotics in pediatrics. Front Cell Infect Microbiol 2023; 13:1147976.

Abstract
β-lactam antibiotics are the most frequently used drugs and the most common drugs that cause allergic reactions in pediatrics. The occurrence of some allergic reactions can be predicted by skin testing, especially severe adverse reactions such as anaphylactic shock. Thus, penicillin and cephalosporin skin tests are widely used to predict allergic reactions before medication in pediatrics. However, false-positive results from skin tests were more often encountered in pediatrics than in adults. In fact, many children labeled as allergic to β-lactam are not allergic to the antibiotic, leading to the use of alternative antibiotics, which are less effective and more toxic, and the increase of antibiotic resistance. There has been controversy over whether β-lactam antibiotics should be tested for skin allergies before application in children. Based on the great controversy in the implementation of β-lactam antibiotic skin tests, especially the controversial cephalosporin skin tests in pediatrics, the mechanism and reasons of anaphylaxis to β-lactam antibiotics, the significance of β-lactam antibiotic skin tests, the current state of β-lactam antibiotic skin tests at home and abroad, and the problems of domestic and international skin tests were analyzed to determine a unified standard of β-lactam antibiotic skin tests in pediatrics to prevent and decrease adverse drug reactions, avoid waste of drugs, and a large amount of manpower and material resource consumption.

Beta-lactam allergy and drug challenge test in children: a systematic review and meta-analysis. Pediatr Res 2023; 93:22-30. [PMID: 35449396 DOI: 10.1038/s41390-022-02076-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 03/16/2022] [Accepted: 03/22/2022] [Indexed: 01/28/2023]
Abstract
BACKGROUND Most cases of beta-lactam allergy in children are likely to be mislabeled. This study aimed to assess the prevalence of true positives, as determined by drug challenge tests, and the rate of false negatives in children with suspected allergies and confirm the safety of the drug challenge test. METHODS We conducted a systematic review and meta-analysis according to established procedures. Study participants were children with suspected beta-lactam allergy who underwent a drug challenge. PubMed MEDLINE, Dialog EMBASE, Cochrane Central Register of Controlled Trials, World Health Organization International Clinical Trials Registry Platform, and clinicaltrials.gov were searched from inception until March 5, 2021. RESULTS The pooled prevalence of (a) positive results in the first challenge was 0.049 (95% CI, 0.041-0.057; I2 = 71%) from 78 studies; (b) serious adverse events was 0.00 (95% CI, 0.00-0.00; I2 = 0.0%) from 62 studies; and (c) positive results in the second challenge after the first negative result was 0.028 (95% CI, 0.016-0.043; I2 = 38%) from 18 studies. CONCLUSIONS The prevalence of children with suspected beta-lactam allergy with true-positive results and false-negative results from the drug challenge test was very low. Serious adverse events resulting from drug challenge tests were also very rare. IMPACT Most children with suspected beta-lactam allergy were likely to be mislabeled. Serious adverse events caused by the drug challenge test were rare. Few false-negative results were obtained from the drug challenge test.

Abstract
BACKGROUND Anaphylaxis is increasing at pediatric age; however, its characterization is hampered by underdiagnosis and underreporting. The aim of this study was to identify the causes of anaphylaxis in children and adolescents in Portugal, thus contributing to a better knowledge of its etiology, clinical manifestations, and management. METHODS During a 10-year period, a nationwide notification system for anaphylaxis was implemented, with voluntary reporting by allergists. Data on 533 patients under 18 years of age with anaphylaxis were included. RESULTS Mean age was 8.5 ± 4.9 years, 61% were male; 45% had asthma. Mean age at the first anaphylaxis episode was 5.3 ± 4.7 years (ranging from 1 month to 17 years of age), 63% at pre-school age. Most reactions occurred at home (57%). Food-induced anaphylaxis was the leading cause (77%). The main culprit foods were cow's milk (32%), tree nuts (16%), shellfish (13%), egg (12%), fresh fruits (11%), fish (8%), and peanut (8%). Other causes included drugs (11%), insect sting (5%), cold-induced anaphylaxis (4%), exercise-induced anaphylaxis (2%), latex (1%), and idiopathic anaphylaxis (1%). Most patients (83%) were admitted to the emergency department; only 46% received adrenaline treatment. Recurrence of anaphylaxis occurred in 41% of the patients (3 or more episodes in 21%). An adrenaline autoinjector was used in 9% of the patients. CONCLUSIONS In the Portuguese pediatric population, food is the leading cause of anaphylaxis. Undertreatment with adrenaline and high recurrence of anaphylaxis highlight the need to improve both the diagnosis and the therapeutic management of this life-threatening entity.

[PMID: 32473813 DOI: 10.1016/j.aller.2020.03.013] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/30/2019] [Revised: 02/28/2020] [Accepted: 03/12/2020] [Indexed: 10/24/2022]
Abstract
BACKGROUND Drug allergies are reactions within the context of drug hypersensitivity reactions, which are caused by immunological mechanisms due to a previously sensitising drug. Beta-lactam antibiotics (BLA) are the leading agents causing drug hypersensitivity reactions in children. The aim of this study is to evaluate the diagnostic importance of in vivo and in vitro diagnostic tests in children with suspected immediate-type BLA hypersensitivity and to investigate the frequency of their use for the final diagnosis. METHODS Patients admitted to the Outpatient Clinic of Division of Paediatric Allergy and Immunology with suspicion of immediate-type BLA hypersensitivity between December 2014 and December 2018 were investigated. Patients with a history of immediate reactions to BLA were examined by performing drug specific IgE, skin prick tests, intradermal tests and drug provocation tests (DPT). RESULTS During the study period, 148 patients were admitted to our clinic with suspected immediate-type BLA hypersensitivity. Forty-eight patients completed all assessment steps and were enrolled in the study. It has been shown that 27 patients did not have drug allergy. BLA hypersensitivity was proven in 21 patients by using in vivo test algorithm. More than half of the patients were diagnosed via skin tests with culprit drug. CONCLUSION Allergy work-up should be performed in patients with immediate reactions to BLA. A skin test can demonstrate BLA hypersensitivity in most patients. Thus, skin tests should be performed prior to the drug provocation test.

Allergol Immunopathol (Madr) 2020; 48:417-423.

Abstract
BACKGROUND Allergy to beta-lactam (βL) antibiotics is highly reported in children, but rarely confirmed. Risk factors for a positive diagnostic work-up are scarce. The primary aim was to characterize the cases of children with confirmed βL allergy, investigating potential risk factors. Secondary aims were to assess the prevalence of allergy to βL in this population and to confirm the safety of less extensive diagnostic protocols for milder reactions. METHODS We reviewed the clinical data from all children evaluated in our Department for suspected βL allergy, over a six-year period. RESULTS Two hundred and twenty children (53% females) with a mean age of 6.5±4.2 years were evaluated. Cutaneous manifestations were the most frequently reported (96.9%), mainly maculopapular exanthema (MPE). The reactions were non-immediate in 59.5% of the cases. Only 23 children (10.5%) were diagnosed with allergy to βL. The likelihood of βL allergy was significantly higher in children with a family history of drug allergy (p<0.001) and in those with a smaller time period between the reaction and the study (p=0.046). The probability of not confirming βL allergy is greater in children reporting less severe reactions (p<0.001) and MPE (p<0.001). We found the less extensive diagnostic protocol in milder reactions safe, since only 4.2% of the children presented a positive provocation test (similar reaction as the index reaction). CONCLUSION This study highlights family history of drug allergy as a risk factor for a positive diagnostic work-up. Larger series are required, particularly genetic studies to accurately determine future risk for βL allergy in children.

Abstract
Adverse drug reaction is defined as any harmful, unintended, and undesired effect of a drug that occurs at doses used for treatment, prevention, or diagnoses. Most of these reactions are classified as type A reactions, which by definition are predictable, common, dose-dependent, and caused by known pharmacological actions of the drug, drug toxicity, and side effects. Allergic reactions are qualified as type B reactions independent of dose, affecting a small population, suggesting that individual patient host factors are important. In pediatric population, β-lactam antibiotics are the most common reason for adverse drug reactions, followed by nonsteroidal anti-inflammatory drugs. In this article, we report the case of a child with several anaphylactic reactions to several drugs, including cefuroxime, amoxicillin/clavulanate, clarithromycin, ibuprofen, and budesonide, in a context of suspected Helicobacter pylori infection.
