Skin testing for immediate hypersensitivity to corticosteroids: a case series and literature review
Background: Medications can modulate the results of skin prick tests SPTs. Short-term corticosteroid therapy does not alter IgE-mediated skin tests, but the impact of long-term oral corticosteroid therapy on SPT results is unclear. A prospective study was carried out in patients with steroid-dependent asthma who received oral corticosteroids for a long period to determine whether this treatment reduced skin test reactivity.
Methods: Thirty-three patients with steroid-dependent asthma median age, 59 years were compared with 66 patients with asthma who served as a control group, matched for age, sex, and atopic status. SPTs with codeine phosphate and a screening battery of standardized allergen extracts were performed before commencement and after at least 1 year of daily oral prednisone treatment median duration, 2 years; median daily dose, 20 mg.
Results: Fifteen patients with corticosteroid-dependent asthma were allergic before treatment, and their sensitization was not changed by long-term treatment with oral corticosteroids. The median wheal diameters induced by codeine phosphate were similar in both groups. The median wheal diameters induced by allergens, and more specifically, by Dermatophagoides pteronyssinus and D.

Question: How do you find products free of the allergens that a patient tests positive to? Answer: The CAMP database allows physicians to provide patients with a list of products free of the allergens the patient is allergic to. Patients should also be instructed how to label read so they can check labels of their personal care products and make sure they are free of their known allergens.

Local antihistamines Examples: azelastine nose or eye , olopatadine eye should be stopped 2 days prior to your appointment. Let your doctor know if you are on any antidepressants or sleep aides before your test, but do not stop them without consulting the prescribing doctor. It is OK to continue to take all your other medicine as you usually do.
Inhaled steroids used for asthma, nasal steroids eg Nasacort, Flonase, Nasonex as well as Singulair montelukast will not interfere with the results of your skin testing and may be continued. High dose oral steroids may effect skin test results, but do not stop any oral steroid medications unless advised by your physician. Allergy Clin. Property Value Status.

I have provided a copy of two below. There is no single protocol or strategy that is evidence based or validated. Please note the frequency of excipients resulting in reactions as well. Prick tests were performed with stock solutions and intradermal tests were performed with dilution. In addition, they also performed testing with excipients commonly found in corticosteroids including carboxymethylcelluose CMC and polyethylene glycol PEG. This study confirms the importance of testing for excipients, especially in patients with confirmed corticosteroid allergy.
The predictive value of this testing is not validated. Also, there is an increased occurrence of corticosteroid allergy in subjects with aspirin exacerbated respiratory disease AERD. In summary, without a challenge there is no confirmation of allergy. Skin testing may be of help but excipients are a concern. I hope this information is of help to you and your practice.

The third reaction again pain at the site and involving the whole extremity but started within one hour - moderate severe pain requiring pain killers, no redness, rash, fever warmth, or noticeable swelling. My fear is further reaction might be more severe. Am I correct in assuming this is a delayed hypersensitive reaction. Question is whether this reaction is to steroid or one of the ingredients? Can I try another form of injectable steroid? If yes, which one or simply go to oral form? She has had a dramatic response to low dose steroid.
The symptoms and time course suggest that the adverse event associated with the intramuscular methylprednisolone is not IgE dependent. Corticosteroids, including methylprednisolone, are associated with a variety of adverse, immunologic reactions including IgE mediated responses.
C Summary Statement Most reported reactions to corticosteroids involved intravenous methylprednisolone and hydrocortisone, and preservatives and diluents have also been implicated. C Allergic contact dermatitis Gell-Coombs type IV reaction due to topical application of corticosteroids is the most common type of allergic reaction induced by this class of drugs.
Members of the PracticeUpdate Dermatology Advisory Board answer the most frequently asked questions by dermatologists. Question: Can patch testing be performed on prednisone?
Answer: Ideally patch testing is performed when a patient is completely off prednisone for at least weeks. However, sometimes it is necessary to patch test while a patient is still on prednisone. Patch testing on prednisone may result in a false negative test as the steroids may blunt a hypersensitivity response but if the patient is allergic to an allergen applied through patch testing and still reacting through the prednisone, hopefully they will mount an allergic reaction at the site of the allergen.
Topical steroids to the site of patch applications should also be avoided for at least a week before the allergens are applied. Answer: Patch testing may be performed while a patient is on antihistamines as they do not effect the Type IV delayed type hypersensitivity reaction.
This is different than prick testing when the patient must stop antihistamines as they do blunt a Type I reaction. If the concern is contact urticaria then antihistamines should be stopped.
Answer: Patch testing should only be conducted if the patient can commit to three visits, patch application, patch removal at 48 hours and a second follow up visit 3- 7 days later. Many contact dermatitis specialists use individual allergens available from outside the country- Canada or Sweden. These allergens are hundreds in number and cover many different specialty series, for example acrylates, hair dressing, rubber series, etc.
Answer: The education of patients after patch testing is very important to the success of the patch testing procedure. Once allergens are identified, patients need to be educated as to what the allergens are they tested positive to, where they are found and how they can avoid them. Physicians must instruct their patients on the names, synonyms of the allergens the patient is allergic to as well as how to label read and avoid the known allergens. It allows the physician to enter the allergens a patient is allergic to into a database and a list is produced that contains products free of the known allergens.
It also eliminates cross reacting chemicals. The patient can then use the list to find products that are safe to use. Question: How do you find products free of the allergens that a patient tests positive to? Answer: The CAMP database allows physicians to provide patients with a list of products free of the allergens the patient is allergic to.

Corticosteroids, including methylprednisolone, are associated with a variety of adverse, immunologic reactions including IgE mediated responses.
C Summary Statement Most reported reactions to corticosteroids involved intravenous methylprednisolone and hydrocortisone, and preservatives and diluents have also been implicated. C Allergic contact dermatitis Gell-Coombs type IV reaction due to topical application of corticosteroids is the most common type of allergic reaction induced by this class of drugs.
Rarely, immediate-type allergic reactions to corticosteroids have been described. Most such reported reactions are due to intravenous administration of methylprednisolone and hydrocortisone.
In most cases, drug specific IgE has not been detected either via skin testing or in vitro tests. Hence, it is unclear whether these reactions are anaphylactoid or represent true IgE-mediated allergy. Some of the reactions are believed to be secondary to the diluent or preservative, rather than the active drug. Evaluation should include skin testing with the corticosteroid in question, although its predictive value is uncertain.
Skin testing with the diluent itself may also be helpful. Because most but not all patients appear to be able to tolerate other corticosteroids, management should focus on finding an alternate agent for future use. If a patient with suspected allergy to a corticosteroid requires treatment with it, rapid induction of drug tolerance should be performed. Many of the immediate reactions to corticosteroids have occurred in aspirin sensitive individuals. In light of the delayed nature of the initial response, patch testing with corticosteroids and preservatives could be considered.
Cutaneous and systemic reactions to polyethylene glycol are described see Ask the Expert question below. Patch and prick testing has been reported. In summary, I would recommend the utilization of an alternative corticosteroid, ideally with a single dose vial and no preservatives. If that is not possible, then I would administer a graded challenge over several days or divide the dose of the methylprednisolone into more than one location.
The other option would be to perform patch testing with different products to see if delayed reactions occur with one more than another. The corticosteroid with the least number of reports of reactions in general is dexamethasone.
Finally, for added safety an oral challenge could be considered with an oral formulation of the corticosteroid chosen. If no systemic response to the oral challenge after several days then the parenteral approach could be used. Of course, all of this must be preceded by a shared decision making discussion with the patient and the other treating physician, recognizing there is little hard evidence to direct your decision.
Solensky R, Khan D. Drug allergy: An updated practice parameter. Ann Allergy Asthma Immunol ; e No other symptoms systemic or otherwise with this reaction.
The reaction resolved fairly promptly with diphenhydramine. This was the first time the patient received a steroid injection. She has subsequently tolerated several courses of oral steroids prednisone and methylprednisolone as well as OTC topical steroids.
The patient is now going to require another steroid injection. Since the patient has tolerated oral methylprednisone several times, would it be safe to assume that the risk of reacting to intra-articular methlyprednisolone would be very low?
Answer: Based upon the history, I would think that a reaction to intraarticular injection of methylprednisolone would be very rare, and that your patient is at very little risk.
However, unfortunately, as you can see from the abstracts copied below, such reactions have occurred, and they have been attributed both to the methylprednisolone molecule per se as well as to the succinate moiety used as a carrier vehicle for intravenous injection. I do not know the preparation that is planned to be used, but I assume it is a succinate. Because such reactions have occurred, you cannot give a carte blanche assurance that she will not experience an adverse event.
However, as noted, she is at very little, if any, increased risk because of her previous local. Nonetheless, because the issue has been raised, you could consider performing a skin test to methylprednisolone. Although this concentration has not been validated in large numbers of individuals, a negative test would certainly give you more reassurance that the administration of methylprednisolone would be safe in your patient. In summary: 1. As you know, anaphylactic reactions to corticosteroids are extremely rare, and this is certainly the case for methylprednisolone.
Nonetheless, such reactions have been reported to both the molecule itself as well as the succinate carrier. Therefore, if you are concerned about the possibility of a reaction, however rare, you could perform skin testing using the above concentrations. If negative, this would give you considerable reassurance that the administration of methylprednisolone would be safe.
If the test was positive, you might consider suggesting another steroid preparation. Report of a case and review of the literature]. Abstract We report a case of fatal anaphylactic reaction to intravenous methylprednisolone succinate therapy developed in a 51 year old asthmatic man with aspirin intolerance and undetermined myocarditis.
However, cases of anaphylactic shock after intraarticular injection of corticosteroids are exceedingly rare. We describe a case of anaphylaxis in a year-old woman after intraarticular injection of synthetic methylprednisolone acetate.
Immediately after injection she developed sneezing, angioedema, tachycardia, and marked hypotension. She responded promptly to treatment with subcutaneous epinephrine. She had received uneventfully one intraarticular injection of the same compound 4 years earlier.
Intradermal skin testing showed strong reactivity to methylprednisolone acetate suspension, moderate reactivity to hydrocortisone and weak reactivity to betamethasone. Tests with dexamethasone. This patient had developed anaphylaxis due to methylprednisolone acetate alone. Although such events are very rare, it is advisable to keep injectable epinephrine in the offices of rheumatologists.
