Abstract
OBJECTIVES Exposure of healthcare workers to antibiotics may cause adverse health effects. Results of environmental contamination with antibiotics, obtained by taking surface wipe samples, can be used as an indicator for potential exposure to these sensitizing drugs. The objective was to describe the results of repeated measurements of contamination with antibiotics on multiple surfaces in hospital wards. Standardized needle and syringe preparation techniques and cleaning procedures were used. METHODS The preparation table and the floor around the waste bin in six wards were sampled and analysed for contamination with the antibiotics amoxicillin, benzylpenicillin, cefotaxime, ceftriaxone, flucloxacillin, meropenem, piperacillin and vancomycin. Sampling was performed in four trials during 8 months. Depending on the outcome of the trials, the cleaning procedure was adapted. Liquid chromatography with tandem mass spectrometry was used for the analysis of the drugs. RESULTS During the four trials, contamination with all eight antibiotics was omnipresent on all preparation tables and floors in the six wards. The highest contamination was found for amoxicillin (1291 ng/cm2). Changing the cleaning procedure did not reduce the level of contamination. CONCLUSIONS Surface contamination with the antibiotics was widespread and most probably caused by spillage during the preparation in combination with an ineffective cleaning procedure. Strategies should be developed and implemented by institutions for safe handling of antibiotics to reduce environmental contamination and potential exposure of healthcare workers to these sensitizing drugs.

Abstract
This article reviews our evolving understanding of penicillin hypersensitivity at the 80th anniversary of penicillin's clinical introduction. Penicillin breakdown products covalently bond to serum proteins, leading to classic drug hypersensitivity. Penicillin remains the most frequently reported drug "allergy." Adverse reactions were presumed, in retrospect incorrectly, to implicate a risk for anaphylaxis, and therefore skin testing for IgE became the focus. Skin test positivity may wane over time. This insight has led to the radical conclusion that penicillin hypersensitivity may not be "forever." Atopic background, other drug allergies, family history, gender, and race are apparently not risk factors for penicillin hypersensitivity. Confirmed penicillin hypersensitivity has declined since the 1960s, potentially due to "cleaner" penicillin products and lower dose oral, instead of parenteral, use. Avoiding penicillins, without evaluation, caused unanticipated problems that have been appreciated only recently including longer hospital stays, increased cost of care, suboptimal outcomes from serious infections, and greater toxicities and costs with alternative antibiotics. There are personal and public health advantages with broadly implemented penicillin allergy delabeling based on a reaction history-based risk assessment. Limited skin testing followed by an oral challenge, if negative, for higher-risk histories, and direct oral challenges in lower-risk individuals are currently the reference standard tests to confirm current tolerance.

Macy E. Why Was There Ever a Warning Not to Use Cephalosporins in the Setting of a Penicillin "Allergy"? THE JOURNAL OF ALLERGY AND CLINICAL IMMUNOLOGY-IN PRACTICE 2021; 9:3929-3933.

Abstract
It is now well-established that avoiding β-lactam antibiotics, when they are the drugs of choice, results in significantly worse long-term global outcomes for patients. Much of this avoidable morbidity has been caused by widespread warnings in electronic health care record systems not to use cephalosporins in the setting of penicillin allergy. High rates, up to 1000-fold higher than now seen, of immunologically mediated reactions were associated with early impure penicillin preparations. This instilled a rational fear of β-lactam-associated anaphylaxis in generations of physicians. In the late 1970s, several editorial comments regarding a potential increased risk to patients given cephalosporins who had a history of a penicillin allergy resulted in the warning that became imbedded in the culture of medicine. Over the past 40 years, compelling data have been developed that refute this warning and showed that the risks of avoiding cephalosporins outweighed the benefits. In late 2017, Kaiser Permanente Southern California completely removed all warnings not to use cephalosporins in the setting of a penicillin allergy. The results have recently been published in JAMA Network Open. This Rostrum article provides some of the backstory on the establishment and removal of this warning for physicians who trained over the past 30 years.

Abstract
Introduction: About 8% of the United States population carries an unconfirmed penicillin 'allergy' in their medical record. Many physicians needlessly avoid other beta-lactam use in individuals with unconfirmed penicillin allergies. There is a significantly increased risk of developing serious antibiotic-resistant infections, and increased morbidity and mortality in those who report penicillin allergy. Areas covered: Within this study, we reviewed the relevant literature on self-reported beta-lactam allergy. We discuss how the myth of serious allergy to penicillin developed and then discuss and in detail clinically significant immunologically mediated hypersensitivity reactions. Following this discussion, we delineate the risks of not using a beta-lactam when it is the drug of choice and then discuss the epidemiology of beta-lactam-associated anaphylaxis, serious cutaneous adverse reactions, and serious systemic immunologically mediated reactions. Following these topics, we further discuss the consensus current best practices to de-label patients with reported penicillin allergy. Expert opinion: An unconfirmed allergy to penicillin offers considerable harm to patients. Many patients have low-risk allergy symptoms to penicillin who could likely tolerate the medication without having an allergic reaction. The current best practices to de-label reported penicillin allergy is the utilization of a single dose oral challenge, with 1 h of observation, in low-risk patients.

Abstract
We present the case of a 53 years old nonatopic female nurse who experienced repeated anaphylactic reactions at work without involvement in drug-specific tasks such as crushing of tablets or preparation of injections. The causal allergen was not identified until a further severe anaphylactic reaction occurred after oral use of cefuroxime during a respiratory infection. Sensitization to cefuroxime was demonstrated by specific IgE, basophil activation test and skin prick test. An inhalation challenge with a dosimeter induced generalized urticaria after a cumulative dose of about 10 μg of the drug, but no asthmatic reaction. Complete exposure cessation was initiated and a 1-year follow-up was without further allergic reactions. We conclude that work-related systemic allergic reactions to β-lactam antibiotics may occur in nurses after inhalation of low doses and without perceived association with drug-specific tasks like handling of antibiotics.

Abstract
PURPOSE OF REVIEW Occupational allergy in healthcare workers is common and can lead to significant costs from both loss of productivity within the workforce as well as those associated with diagnosis and treatment. This review aims to provide an update on drugs implicated in causing occupational allergy. RECENT FINDINGS Drugs traditionally reported as causing occupational allergy, such as penicillin, remain problematic. However, as their use reduces and newer drugs, such as cephalosporins, are used more frequently there is a changing pattern to occupational sensitization. In some studies up to 17% of healthcare workers now appear sensitized to cephalosporins. Other drug classes also reported include proton pump inhibitors and benzodiazepines. Interestingly, drugs such as omeprazole and tetrazepam rarely cause allergy in patients but can be very sensitizing if applied topically or inhaled. Recent studies involving pharmaceutical company employees show that this problem can no longer be considered primarily related to healthcare workers. SUMMARY The diagnosis of occupational allergy to drugs can be complicated and has been shown to take up to 5 years from the onset of symptoms. Ultimately, workplace avoidance remains key; however, an up to date awareness of culprit drugs and the patterns of allergy seen are key to a prompt resolution of symptoms.

Abstract
Anaphylaxis is a systemic allergic reaction, potentially life-threatening that can be due to nonoccupational or, less commonly, to occupational triggers. Occupational anaphylaxis (OcAn) could be defined as anaphylaxis arising out of triggers and conditions attributable to a particular work environment. Hymenoptera stings and natural rubber latex are the commonest triggers of OcAn. Other triggers include food, medications, insect/mammal/snake bites, and chemicals. The underlying mechanisms of anaphylactic reactions due to occupational exposure are usually IgE-mediated and less frequently non-IgE-mediated allergy or nonallergic. Some aspects of work-related allergen exposure, such as route and frequency of exposure, type of allergens, and cofactors may explain the variability of symptoms in contrast to the nonoccupational setting. When assessing OcAn, both confirmation of the diagnosis of anaphylactic reaction and identification of the trigger are required. Prevention of further episodes is important and is based on removal from further exposure. Workers with a history of OcAn should immediately be provided with a written emergency management plan and an adrenaline auto-injector and educated to its use. Immunotherapy is recommended only for OcAn due to Hymenoptera stings.

Abstract
Purpose Cephalosporins can induce occupational allergies, such as asthma, urticaria, and anaphylaxis. We investigated the prevalence and risk factors of sensitization to cephalosporin. Methods A total of 161 health care workers (HCW), including 138 nurses and 23 pharmacists, and 86 unexposed non-atopic healthy controls were recruited from a single tertiary hospital and the general population. A questionnaire regarding work-related symptoms was administered along with skin prick tests (SPT) to the three most commonly used cephalosporins (cefotiam, ceftriaxone, and ceftizoxime). Serum specific IgE antibodies to conjugates of the three cephalosporins and human serum albumin (HSA) were measured by enzyme-linked immunosorbent assay (ELISA). Binding specificities were confirmed by ELISA inhibition tests. Results The prevalence of work-related symptoms in association with cephalosporins was 17.4%. The sensitization rate to any cephalosporin was 3.1% by SPT. Sensitization rates determined by measurement of serum specific IgE antibodies were 17.4% for any cephalosporin, 10.4% for cefotiam, 6.8% for ceftriaxone, and 3.7% for ceftizoxime. A personal history of any antibiotic allergy was a risk factor for work-related symptoms (OR, 24.93; 95% CI, 2.61-238), but not for the presence of serum specific IgE antibodies to cephalosporins (OR, 0.9; 95% CI, 0.18-4.53). A personal history of atopic dermatitis was a risk factor for the presence of serum specific IgE antibodies to cefotiam-HSA conjugate (OR, 6.30; 95% CI, 1.23-32.3). Conclusions A high cephalosporin sensitization rate (17.4%) was detected by ELISA in HCW exposed to cephalosporins. Monitoring of serum specific IgEs to cephalosporin-HSA conjugates will be useful for detecting sensitized subjects.

Abstract
BACKGROUND Delayed allergic skin reactions to drugs are common iatrogenic diseases mediated by activation of specific T cells in the skin. METHODS To better understand the role of T cells in these diseases, we developed a mouse model of drug allergy induced by skin sensitization to amoxicillin (amox), a penicillin antibiotic frequently involved in delayed drug allergy. RESULTS Whereas wild-type mice could not be sensitized to amox, CD4+ T-cell-deficient mice developed an amox-specific allergic skin response, mediated by IFN-gamma-producing CD8+ T cells. Amox-specific CD8+ T cells, induced in lymphoid organs at a high frequency during sensitization, were recruited in the skin upon challenge. CD8+ T cells were effectors of the allergic skin reaction to amox as in vivo treatment with depleting anti-CD8 mAbs abrogated the skin inflammatory reaction and as purified CD8+ T cells could adoptively transfer the allergic response to naive recipients. CONCLUSION CD8+ T cells mediate penicillin skin allergy.

Abstract
Treponema pallidum resistance to azithromycin has been documented in the US, Canada, and Ireland. We found no evidence of resistance to azithromycin in specimens from 141 patients with syphilitic lesions in Madagascar suggesting resistance is geographically isolated and supporting use of azithromycin as alternative treatment for early syphilis in Madagascar.
