[12], In pediatric cases, EpsteinBarr virus and enteroviruses have been associated with SJS. Anti-convulsants: lamotrigine, carbamazepine, phenytoin, phenobarbitone, Nevirapine (non-nucleoside reverse-transcriptase inhibitor), Nonsteroidal anti-inflammatory drugs (NSAIDs) (oxicam type mainly), Macules flat, red and diffuse (measles-like spots) or purple (purpuric) spots, Targetoid as in erythema multiforme (target like skin lesions), Eyes (conjunctivitis, less often corneal ulceration, anterior uveitis, panophthalmitis) red, sore, sticky, photosensitive eyes, Lips/mouth (cheilitis, stomatitis) red crusted lips, painful mouth ulcers, Pharynx, oesophagus causing difficulty eating, Genital area and urinary tract erosions, ulcers, urinary retention, Upper respiratory tract (trachea and bronchi) cough and respiratory distress, Pigment change patchwork of increased and decreased pigmentation, Skin scarring, especially at sites of pressure or infection, Loss of nails with permanent scarring (pterygium) and failure to regrow, Scarred genitalia phimosis (constricted foreskin which cannot retract) and vaginal adhesions (occluded vagina). Treatment with corticosteroids is controversial. Doctors are advised to carefully consider using these medications as first-line treatments, particularly if there are safer alternatives. The site is secure. [1][3] Erythema multiforme (EM) is generally considered a separate condition. [37], In some East Asian populations studied (Han Chinese and Thai), carbamazepine- and phenytoin-induced SJS is strongly associated with HLA-B*1502 (HLA-B75), an HLA-B serotype of the broader serotype HLA-B15. At this point, you may be confused. Review of toxic epidermal necrolysis. People with systemic lupus erythematosus or HIV infections are more susceptible to drug-induced SJS. Accessibility [26] A classification first published in 1993, that has been adopted as a consensus definition, identifies StevensJohnson syndrome, toxic epidermal necrolysis, and SJS/TEN overlap. We present a case of a 37-year-old male with no past medical history who presented to the dental emergency clinic complaining of dysphagia and burning sensation in the mouth. 2017. Taiwanese, Japanese, and Malaysian individuals expressing the CYP2C9*3[46] variant of CYP2C9, which has reduced metabolic activity compared to the wild type (i.e. Fakoya AOJ, Omenyi P, Anthony P, Anthony F, Etti P, Otohinoyi DA, Olunu E. Current perspectives on Stevens-Johnson syndrome and toxic epidermal necrolysis. However, the current ocular surface inflammation cannot be ignored. What are the signs and symptoms of Stevens-Johnson syndrome? [12] SJS, SJS/TEN, and TEN are considered a single disease with common causes and mechanisms.[8]. Contact us P.O. This drug is useful to treat epilepsy, bipolar disorder and other conditions. We are vaccinating all eligible patients. However concerns have been raised that they may increase the risk of infection, impair wound healing and other complications, and they have not been proven to have any benefit. Classification of Stevens-Johnson syndrome? [13] Determining what drug is the cause is based on the time interval between first use of the drug and the beginning of the skin reaction. If ulcerated, prevent vaginal adhesions using intravaginal steroid ointment, soft vaginal dilators. google_ad_client: "ca-pub-9759235379140764", This means that blisters and erosions appear when the skin is rubbed gently. Dermatologists and surgeons tend to disagree about whether the skin should be debrided. that all individuals found to express this HLA serotype avoid treatment with abacovir. The cornea is transparent without epithelial punctate opacity, C. The corneal fluorescence staining showed punctate staining, D. Palpebral conjunctiva is congested and edematous, and pseudomembrane can be seen. Examine daily for extent of detachment and for infection (take swabs for bacterial culture), Topical antiseptics (eg, silver nitrate, chlorhexidine [but not silver sulfadiazine as it is a sulfa drug]), Dressings such as gauze with petrolatum, non-adherent nanocrystalline-containing silver gauze or biosynthetic skin substitutes can reduce pain, Avoid using adhesive tapes and unnecessary removal of dead skin; leave the blister roof as a biological dressing. It is slightly more common in females than in males. CD4+ T cells) to initiate autoimmune reactions that attack self tissues. Put the mouthwash solution in glass or syringe. And you may have scars. [7][47] In addition to abnormalities in drug-metabolizing enzymes, dysfunctions of the kidney, liver, or GI tract which increase a SCARs-inducing drug or metabolite levels are suggested to promote SCARs responses. The symptoms of erythema multiforme may resemble other skin conditions. WebEarly symptoms of SJS include fever and flu-like symptoms. In either case, this binding appears to develop only on certain T cell receptors. Perforin and granzyme B can be detected in early blister fluid and it has been suggested that levels may be associated with disease severity. Eye care is undertaken 36 times each day depending on severity of eye involvement. It is usually caused by a medicine reaction rather than an infection. Depending on local protocols, if SCORTEN is more than 1, the patient is managed in intensive care, a burns unit or a specialist dermatology unit of a regional hospital. Anemia occurs in virtually all cases (reduced hemoglobin). Patch testing rarely identifies the culprit in StevensJohnson syndrome / toxic epidermal necrolysis following recovery, and is not recommended. Other causes of StevensJohnson syndrome / toxic epidermal necrolysis. This screening is widely implemented. The diagnosis may therefore change during the first few days in hospital. [13] The skin pattern most commonly associated with SJS is widespread, often joined or touching (confluent), papuric spots (macules) or flat small blisters or large blisters which may also join. Oakley AM, Krishnamurthy K. In StatPearls [Internet] Treasure Island, FL: StatPearls Publishing; 2020. [53], SJS (with less than 10% of body surface area involved) has a mortality rate of around 5%. Symptoms can include: Painful blistering of the skin and mucous membrane involvement. Both SJS and TEN are believed to be variants of the same condition that can be differentiated by the degree of skin and mucous membrane In severe cases, it can lead to extensive tissue damage and scarring that results in visual impairment and, rarely, blindness. Neutropenia (reduced neutrophils), if present, is a bad prognostic sign. [30][32], Like other SCARs-inducing drugs, SJS-inducing drugs or their metabolites stimulate CD8+ T cells or CD4+ T cells to initiate autoimmune responses. Stevens-Johnson syndrome signs and symptoms include: If you have Stevens-Johnson syndrome, several days before the rash develops you may experience: StevensJohnson syndrome / toxic epidermal necrolysis is suspected clinically and classified based on the skin surface area detached at maximum extent. [54] It is helpful to calculate a SCORTEN within the first 3 days of hospitalization. Due to the low clinical incidence rate of SJS, it is not easy to diagnose SJS in the early stage. They have some natural killer cell activity and can probably kill keratinocytes by direct contact. Conjunctivitis occurs in about 30% of children who develop SJS. Bethesda, MD 20894, Web Policies Since the human population expresses some 13,000 different HLA serotypes while an individual expresses only a fraction of them and since a SJS-inducing drug or metabolite interacts with only one or a few HLA serotypes, a drug's ability to induce SCARs is limited to those individuals who express HLA serotypes targeted by the drug or its metabolite. Synechiae can be released by applying the eye ointment. WebIn Stevens-Johnson syndrome, the immune system overreacts to a medication or infection. [12] Malaria and trichomoniasis, protozoal infections, have also been reported as causes. WebSJS and TEN are rare conditions; combined, they affect fewer than 8 cases per million persons per year. After the inflammation is controlled, the drug can be stopped. [9] A rash of round lesions about an inch across arises on the face, trunk, arms and legs, and soles of the feet, but usually not the scalp. [8] A skin biopsy is helpful, but not required, to establish a diagnosis of SJS and TEN.[8]. [2] Overall, the risk of death with SJS is 5 to 10%. [1] Together with toxic epidermal necrolysis (TEN) and StevensJohnson/toxic epidermal necrolysis (SJS/TEN), it forms a spectrum of disease, with SJS being less severe. 2 The One study concluded: "Even when HLA-B alleles behave as strong risk factors, as for allopurinol, they are neither sufficient nor necessary to explain the disease."[43]. Stopping nonessential medications. Some clinicians prescribe high doses of corticosteroids for a short time at the start of the reaction, e.g prednisone 12 mg/kg/day for 35 days. Use the stick to delicately clean the mucosa of cheek, gum, tongue; change sticks frequently and avoid injury to mucosal lesions. Stevens-Johnson syndrome/toxic epidermal necrolysis often begins with a fever and flu-like symptoms. Stevens-Johnson syndrome is a medical emergency that usually requires hospitalization. Unable to load your collection due to an error, Unable to load your delegates due to an error. [12], SJS is a type IV hypersensitivity reaction in which a drug or its metabolite stimulates cytotoxic T cells (i.e. Toxic epidermal necrolysis lips and mouth. Epub 2017 Feb 20. Why Is Dexamethasone Given Prior To Chemo? No drug is implicated in about 20% of cases. Harris V, Jackson C, Cooper A. Int J Mol Sci. Alternatively, a drug or its metabolite may stimulate these T cells by inserting into the groove on a HLA protein to serve as a non-self epitope or bind outside of this groove to alter a HLA protein so that it forms a non-self epitope. Drug specific CD8+ cytotoxic lymphocytes can be detected in the early blister fluid. Rev Assoc Med Bras (1992). Typical prodromal symptoms of Stevens-Johnson syndrome are as follows: Cough productive of a thick, purulent sputum. Before treatment with abacavir, the USA Food and Drug Administration recommends screening for HLA-B*57:01 in Caucasian populations. In addition to acting through HLA proteins to bind with a T-cell receptor, a drug or its metabolite may bypass HLA proteins to bind directly to a T-cell receptor and thereby stimulate CD8+ T or CD4+ T cells to initiate autoimmune responses. Lerch M, Mainetti C, Terziroli Beretta-Piccoli B, Harr T. Clin Rev Allergy Immunol. [36], Variations in ADME, i.e. Fluoromilone is anti-inflammatory and cyclosporine inhibits immune response. When the ocular surface damage of SJS patients is mild, there are few signs and mild symptoms. Due to the low clinical incidence rate of SJS, it is not easy to diagnose SJS in the early stage. Then the top layer of affected skin dies, sheds and begins to heal after several days. [8] Patients with SJS or TEN caused by a drug have a better prognosis the earlier the causative drug is withdrawn.[8]. Treatments for Stevens-Johnson syndrome include:Stopping the medication that has caused the problem.Replacing electrolytes with intravenous (IV) fluids.Using non-adhesive dressings on the affected skin.Using high-calorie food, possibly by tube-feeding, to promote healing.Using antibiotics when needed to prevent infection.Providing pain relief medications.More items [30][36] In general, these associations are restricted to the cited populations. enable_page_level_ads: true Case reports and small patient series have reported benefit from active adjuvant treatments delivered during the first 2448 hours of illness. More than 200 medications have been reported in association with Stevens-Johnson syndrome/toxic epidermal necrolysis. It may take weeks to months for symptoms and signs to settle. Similar to NSAIDs, paracetamol (acetaminophen) has also caused rare cases[27][28] of SJS. In Asian countries, the incidence of SJS is about 8/1million per year. The PubMed wordmark and PubMed logo are registered trademarks of the U.S. Department of Health and Human Services (HHS). [13] The distinction between SJS, SJS/TEN overlap, and TEN is based on the type of lesions and the amount of the body surface area with blisters and erosions. National Library of Medicine All rights reserved. So once the diagnosis is made, we should attach great importance to it and immediately stop all suspicious drugs and drugs with similar structures. [41][42] This has clinical relevance as it is agreed upon that prior to starting a medication such as allopurinol in a patient of Chinese descent, HLA-B*58:01 testing should be considered. But people with a gene called HLA-B1502 and HLA B1508 have an increased risk of Stevens-Johnson syndrome if they take this drug.
