Corticosteroid allergy is diagnosed by performing special allergy tests, ie patch tests , and in some cases intradermal tests. There are many topical corticosteroid preparations available; allergy may arise to one or more of these. Positive patch test reactions to budesonide and tixocortolpivalate are a good indicator of corticosteroid allergy. These 2 corticosteroids are often included in the standard panel. Further testing with other corticosteroids should be done if these 2 indicators are positive.

Patch testing may be performed using a standard corticosteroid series. In ideal conditions, a positive patch test result to both the commercial preparation and the isolated active corticosteroid agent should be achieved to confirm the diagnosis. The standard corticosteroid series consists of the following allergens. Positive patch tests to corticosteroids Positive patch test to topical corticosteroids. Corticosteroids are classified according to their structure. A specific compound is used to screen for class-specific reactions.

When patch tests show allergy to a specific topical steroid, it is likely that the patient will also be allergic to others in the same class. Your doctor or dermatologist should give you a list of all the names of the corticosteroids or corticosteroid groups to which you are allergic. You must avoid using any preparations that contain any of the listed corticosteroids. Many anti-inflammatory skin preparations, antibiotic creams and ointments, eye and ear preparations contain corticosteroids hydrocortisone.

If purchasing over-the-counter products alert your pharmacist to the fact that you have a contact allergy to corticosteroids and provide them with the list of the corticosteroids you are allergic to. Note that a non-prescription cream may contain an illegal corticosteroid. Always alert your doctor to the fact that you have a contact allergy to corticosteroid so that they can prescribe you a suitable alternative if necessary.

Your dermatologist may have further specific advice, particularly if you are highly sensitive to a corticosteroid. See smartphone apps to check your skin.

Allergy to topical corticosteroid — codes and concepts open. Topical corticosteroid allergy, Budesonide allergy, Betamethasonevalerate allergy, Tiamcinolone acetonide allergy, Tixocortolpivalate allergy, Alclomethasone, dipropionate allergy, Clobetasolpropionate allergy, Dexamethasonephosphate disodium salt allergy, Hydrocortisonebutyrate allergy. One example of a nongenomic effect is the Acute behavioral changes induced by corticosteroids through a glycoprotein acid cytosolic receptor protein G that would modulate the speed of neuronal discharge or modify the reuptake extraneuronal neurotransmitter transporter of cations.

The main anti-inflammatory effect of GCs is based on the inhibition of the genetic transcription of numerous genes that encode proinflammatory proteins, which include numerous cytokines -interleukins IL. This anti-inflammatory effect is also through the synthesis of anti-inflammatory proteins, such as lipocortin 1, SLPI serum leukoprotease inhibitor , IL or the antagonist of IL-1 receptors [6,7]. Systemically used GC are classified as short acting S hours , intermediate acting I: hours and long acting L: hours based on their duration of ACTH suppression and by their relative GC versus MC potency, these relative potencies of CS differ due to their affinity for the receptor [8,9].

Table 1. I : Inhalated. Glucocorticoids are active by any route of administration. Times at maximum concentration c tmax orally are reached around 90 min. Most glucocorticoids except for hydrocortisone bind albumin to a greater degree and while they keep their water-soluble ester they are free. Their apparent volumes of distribution Vd oscillate between 0. All metabolites resulting are conjugated with glucuronic acid or with sulfate and are eliminated by renal or biliary [8,9].

Broadly, hypersensitivity reactions to steroids are divided into two categories: immediate reactions Urticaria, Anaphylaxis, bronchospasm, etc.. Of the types of Hypersensitivity Reactions to Steroids, Delayed Hypersensitivity Reactions type IV are much more frequent with an estimated incidence of Contact dermatitis to corticosteroids of 0.

These delayed hypersensitivity reactions occur more readily following topical exposure to corticosteroids than via other routes of administration []. In order of presentation, hypersensitivity reactions are more frequent to topical administration followed by intravenous administration and, to a lesser extent, inhaled and nasal administration [13].

While the presentation of immediate hypersensivity reactions has a lower prevalence calculated of 0. Bundgaard has proposed a possible mechanism of allergy for non-mediated IgE Reactions, which is at least partly due to a steroid-glyoxal, a degradation product of cortisol and hydrocortisone, with an aldehyde group in the C21 position easily forms Schiff bases with reactive carbonyl groups of lysine or arginine, in this way being responsible for irreversible bonding to the guanidinic groups of arginine, thus forming a stable hapten for the presentation of the steroid carbon rings to the body immune system [14,15].

Glyoxal or Ethanedial is a 2-carbon aldehyde with carbonyl groups on both carbons whose molecular formula is C 2 H 2 O 2 or OHCCHO through the controlled oxidation of ethanol with nitric acid, is the simplest of the dialdehydes two aldehyde groups and can function like a hapten to drive a hypersensivity reaction, and this haptenized steroid, specially its rings estrcture can cause an immunological reaction in future re- exposures.

IgE Reactions may be induced by salts, such as succinate or rarely by certain diluents such as carboxymethylcellulose or metabisulfite. Succinate as an ingredient is more likely to have an allergic reaction compared to others such as sodium phosphate, because the succinate esters have greater solubility in water and high affinity for different serum proteins, which can lead to an IgE-mediated reaction and gives it an immunogenic role.

Due to the structural similarity of the succinate and to a lesser extent acetate radicals to the steroid-glyoxal it is possible that these succinate radicals are able to mimic the ability of the steroid glyoxal to bind the arginine guanidine groups in the albumin of human serum in a more efficient way than acetate radicals.

In the case of topic reactions, the most common antigen is cortisol which has low molecular weight and high lipofilicity, both charateristics for an ideal allergen, but at other times the reaction may be due to other constituents of the creams, such as neomycin or cetylesteryl alcohol [16,17].

The most common hypersensvity reactions to steroids are non-mediated IgE reactions being mediated by direct activation of components of innate immune system Mast cells, basophils, and the complement Cascade [16,17]. Along with the allergic reactions observed in specific steroids, it was evident that some patients reported positive results to patch tests for corticosteroids with which they had not previously been exposed.

This indicated the existence of cross-reactivity among other corticosteroids. In Coopman, et al. In based on skin patch test results obtained from a large cohort of corticosteroid allergic patients [20]. The groups of cross-reacting molecules are classified into: Group A hydrocortisone type: no substitution on the D ring except a short chain ester on C2 or a thioester on C21 ; Group B triamcinolone acetonide type: Acetonides.

C16, Ccis-ketal or -diol structure , Group C betamethasone type: Methylation on C16 and D hydrocortisonebutyrate type. There is a high cross-reactivity between corticosteroids in each group, as well as between group D2 and groups A and B. Hydrocortisonebutyrate from group D2 in the skin is enzymatically converted to hydrocortisone of group A. In the same way other corticosteroids may generate cross-reactivity with group A, for example the methyl-prednisolone aceonate of group D2 becomes subsequent to several enzymatic steps in methylprednisolone group A and the prednicarbate of group D2 becomes prednisolone also of group A And corticosteroids from the group D1 shows a minimal low cross-reactivity with the other groups [19,20].

Table 2. As in any Adverse Drug Reaction ADR the diagnosis is primarily clinical, demonstrating a temporal-causal relationship between the clinical reaction and the steroid, however to is of primary importance to differentiate between IgE mediated and non IgE mediated hypersensivity Reaction.

Currently there are several diagnostic studies that can suppot the diagnosis of Steroid Allergy but unfortunately there are no standardized tests to confirm steroid allergies [21,22]. Figure 4. In the case of an Immediate IgE Hypersensivity Reaction, test in vitro with ImmunoCAP is only available for Dexamethasone and the sensitivity and specificity is unknown, skin testing can provide sufficient information for a diagnosis of corticosteroid-associated immediate hypersensitivity with a higher sensitivity and negative predictive value than in vitro test.

In the case of Immediate non IgE Hypersensivity Reaction, the only available in vitro test is the Basophil Activation Test, while the Skin testing are not validated and lack specificity and sensitivity, so in cases of diagnostic suspicion the gold standard will be the Challenge Provocation Testing [21,22]. In the case of Delayed Hypersensivity Reactions, the diagnosis can be supported with positive patch test or test of cellular immunity such as Lymphocyte Transformation Test LTT and in the same way of non IgE Reactions, in cases of diagnostic suspicion the gold standard will be the Challenge Provocation Testing.

Steroids allergy is not typically drug-specific and co-sensitizations or cross-reactivity between members of the same family are common. Therefore, it is recommended to study steroids by group of families based on Coopman or ABCD classification system, when a true hypersensivity reaction is presented in order to offer a therapeutic alternative [21,22].

The main treatment consists of avoiding re-exposure to the causative drug and offering an alternative treatment by administering a steroid from a different structural group, considering group C of Coopman System Classification are the steroids with less allergenicity such as betamethasone and dexamethasone or a new order steroid like deflazacort, and only in case of no alternative of treatment to assess desensitization currently cases of successful desensitization to dexamethasone, hydrocortisone, prednisone and methylprednisolone [23,24].

We reviewed the literature using the search terms "hypersensitivity to steroids, adverse effects of steroids, steroid allergy, allergic contact dermatitis, corticosteroid side effects, and type I hypersensitivity" to identify studies or clinical reports of steroid hypersensitivity.

We discuss the prevalence, mechanism, presentation, evaluation, and therapeutic options in corticosteroid hypersensitivity reactions. There is a paucity of literature on corticosteroid allergy, with most reports being case reports. Most reports involve non-systemic application of corticosteroids. Steroid hypersensitivity has been associated with type I IgE-mediated allergy including anaphylaxis. The overall prevalence of type I steroid hypersensitivity is estimated to be 0. Allergic contact dermatitis ACD is the most commonly reported non-immediate hypersensitivity reaction and usually follows topical CS application.

Atopic dermatitis and stasis dermatitis of the lower extremities are risk factors for the development of ACD from topical CS. Patients can also develop hypersensitivity reactions to nasal, inhaled, oral, and parenteral CS. Thus, even if Bonds did use steroids between and , he violated no rules — and.
