Twenty patients had reactions to drugs, vaccines and consumer products containing PEG, but no history of reactions to polysorbate, while four patients described reactions to both PEG and polysorbate containing products (ID12, ID14, ID16, ID24). Mortz CG, Kjaer HF, Rasmussen TH, Rasmussen HM, Garvey LH, BindslevJensen C. Allergy to polyethylene glycol and polysorbates in a patient cohort: Diagnostic workup and decision points for vaccination during the COVID19 pandemic. In summary, evaluation for excipient allergy is challenging; the reproducibility of SPT test is time dependent and reactivity will decline over time, while BaHR seems to be a poor marker. Clin Exp Allergy. Copenhagen Warnings Clipboard, Search History, and several other advanced features are temporarily unavailable. In reviewing the literature, it seems skin testing for IgE mediated PEG allergy may result in false negative using available Medrol solutions with and without PEG. Two patients were lost to followup for the reevaluation in 2021. For safety reasons we did not offer a polysorbate vaccine in those with present PEG allergy including elevated specific IgE and polysorbate sensitization. Denmark. , Clinical manifestations and impact on daily life of allergy to polyethylene glycol (PEG) in ten patients, Safety of polysorbate 80 in the oncology setting.

An additional challenge in Denmark is, that the viral vector vaccine from JJ and AZ are not recommended by the Danish health authorities due to the risk of thrombotic side effects. Ten patients with certain PEG allergy and one with possible PEG allergy, all 11 with unlikely polysorbate allergy, were offered a JJ vaccine; four accepted and were vaccinated without reaction. The https:// ensures that you are connecting to the Polyethylene glycol allergic patients may show crossreactions to PEGylated drugs and structurally similar polymers such as polysorbates and poloxamers. Interdiscip Sci. 14. 5 Only six patients could not be offered vaccines containing PEG or polysorbate due to certain clinical reactions to both excipients. There is a small risk of experiencing a serious allergic reaction to certain ingredients in the vaccine polyethylene glycol or polysorbate but most reported reactions to the vaccines. Most primary reactions were elicited by depotsteroid injections followed by laxatives (Table1) as also reported in other studies. .

PEG 3350 (MiraLAX) testing was performed using sequential skin pricks at 1.7 mg/mL, 17 mg/mL, and 170 mg/mL. PEG, as well as another compound additive called polysorbate (which is used in the Johnson & Johnson vaccine), can trigger an immediate allergic reaction, though it is rare. Odense C Furthermore, labeling of excipients in drugs and consumer products varies and different names are used. Affiliations 1 Division of Clinical Immunology and Allergy, Department of Medicine, Hpital Maisonneuve-Rosemont, Universit de Montreal, Montreal, Quebec, Canada. That means that we do not have any data confirming that vaccines containing PEG have caused any severe allergic reactions. Clin Exp Allergy. An allergic reaction would likely occur very soon after receiving the vaccine, probably within 15-30 minutes. , , We here describe the allergological workup program leading to a decision for safe COVID19 vaccination in patients with a history of an allergic reaction to drugs, vaccines and mouth hygiene products containing PEG or polysorbate and sensitization or positive challenge to one or more of these excipients. BruusgaardMouritsen MA, Johansen JD, Garvey LH. How to know if you're allergic to the COVID-19 vaccines by Moderna, Pfizer, or J&J. This site needs JavaScript to work properly. PEG 20,000 (concentration 0.01%, 0.1%, 1%, 10%, 20%, titrated, not in duplicate) and Poloxamer 407 (10%) was obtained from the laboratory of Medical Allergology, Gentofte Hospital, Hellerup, Denmark. At the primary evaluation (n=25) allergy was concluded based on a certain case history and positive SPT in 17 patients, in 6 by a certain or possible case history and positive BaHR (negative SPT in 5/6, no SPT in 1/6) and two with a certain case history were negative in both SPT and BaHR test but were positive on oral challenge with PEG 3350. Systemic reactions to PEG are dependent on a combination of the molecular weight and absolute amount of PEG in the culprit medication, which can differ substantially between injectable and oral forms of PEG.4 Furthermore, the threshold needed to induce a systemic reaction likely differs among individuals.4 These facts make interpretation of skin tests difficult in patients who have yet to receive a COVID-19 vaccine. Immediate hypersensitivity to COVID-19 vaccines: Focus on biological diagnosis. 21 14 Since January 2020 Elsevier has created a COVID-19 resource centre with free information in English and Mandarin on the novel coronavirus COVID-19. From August 01, 2015 to December 31, 2020 a total of 21 adults were diagnosed with PEG and/or polysorbate allergy at the Allergy Center, Odense University Hospital.

It likely would be characterized by a skin-related problem, such as a raised, itchy rash or swelling of the lips or eyes. It is used to conjugate with medications to improve their efficiency, their effectiveness and ability to generate an immune response. In our cohort, when comparing SPT at diagnosis with SPT at reevaluation in 2021, half of the patients had lost their skin test reactivity (Table2), however some reacted with systemic urticaria after the SPT. One of these patients (ID16) had a primary reaction to the AZ vaccine, the other (ID18) had a previous reaction to several drugs containing PEG (TableS1). Other allergic reactions can include a cough, chest tightness, wheezing or shortness of breath. 2021 Mar 26:S1081-1206(21)00188-5. doi: 10.1016/j.anai.2021.03.012.

Results: The prevalence of PCP-documented vaccine allergy in Canada was 0.037% (395/1,055,677) and of PEG allergy was 0.0009% (10/1,055,677). 5 Allergic reactions to vaccines are not common, but they are possible. The .gov means its official. The IgE positive patients did not all have a severe history to PEG, two of four had anaphylaxis but two others had generalized urticaria. Eleven were offered the JohnsonJohnson vaccine; four were vaccinated successfully, seven abstained. Polyethylene glycol and polysorbate skin testing in the evaluation of coronavirus disease 2019 vaccine reactions: Early report. Reactions to mRNA vaccines have brought patients in who are vaccine hesitant due to systemic reactions after colonoscopy prep with Miralax. The size of the resulting wheals was recorded after 15 and 30min and wheal size was measured on the longest and shortest perpendicular axis, numbers were added and divided by two to obtain the mean wheal diameter. No reactions to the Pfizer/BioNTech (PB) vaccine were seen in SPT although it was the only vaccine tested in all 23 patients. Funding: The authors have no funding sources to report. During the COVID19 epidemic focus has been on these two excipients as they are excipients in the first vaccines on the market in Europe and possible culprits for allergic reactions to the COVID19 vaccines. The decision to offer COVID19 vaccination was made after a risk evaluation based on this information (Table4, Figure1). This means that the timing of allergy testing is important to get reliable results as also seen for other drug allergens. Although not knowing the fraction absorbed from the GI tract, we performed titrated oral challenges to verify or rule out allergy in those with possible allergy. An official website of the United States government. , 2021; cea . Learn more Results: Ten patients with PEG allergy were found in the retrospective cohort. Twelve patients fulfilled the WAO criteria for anaphylaxis for at least one reaction with WAO score 5 in five patients, WAO score 4 in two and WAO score 3 in five. There is an urgent need for an allergological workup program in patients with allergy to PEG and/or polysorbates to make decisions for safe COVID19 vaccinations. 10.1016/j.bja.2020.12.020 26 By Amy Isler, RN, MSN, CSN Wenande EC, Skov PS, Mosbech H, Poulsen LK, Garvey LH.

The allergy status of the patients was reclassified in 2021 as certain, possible and unlikely based on history and disease course, testing on primary evaluation (TableS1) and reevaluation (Tables2 and and3).3). The clinical need for skin testing and test selection was provider-determined at the time of evaluation. Wheals 3mm larger than the negative control were considered positive. Comorbidity is shown in TableS1. Bethesda, MD 20894, Web Policies Bookshelf None of the patients with PEG allergy had a documented allergy to a CIMCP. In a presentation at the American Academy of Allergy, Asthma, and Immunology Annual Meeting, John Kelso, MD, a practicing allergist in the Division of Allergy, Asthma, and Immunology at Scripps Clinic and voluntary health sciences clinical professor at the University of California San Diego School of Medicine, said that Even in the rare patient who is PEG allergic, we still dont know if there is enough PEG in the vaccine to actually cause a reaction.
