Stevens–Johnson syndrome
SpecialtyDermatology Edit this on Wikidata

Stevens-Johnson syndrome (SJS) is a life-threatening condition affecting the skin in which cell death causes the epidermis to separate from the dermis. The syndrome is thought to be a hypersensitivity complex affecting the skin and the mucous membranes. Although the majority of cases are idiopathic, the main class of known causes is medications, followed by infections and (rarely) cancers.

Classification

There is agreement in the medical literature that Stevens-Johnson syndrome can be considered a milder form of toxic epidermal necrolysis (TEN). However, there is debate whether it falls on a spectrum of disease that includes erythema multiforme and erythema multiforme major (also known as erythema multiforme majus).[1][2][3][4][5]

Epidemiology

SJS is a rare condition, with a reported incidence of around one case per million people per year. In the United States, there are about 300 new diagnoses per year.

Causes

SJS can be caused by infections (usually following viral infections such as herpes simplex virus, influenza, mumps, cat-scratch fever, histoplasmosis, Epstein-Barr virus, or similar), allergic reactions to drugs, (Dicloflex, fluconazole,[6] valdecoxib, sitagliptin, penicillins, barbiturates, sulfas, phenytoin, Azithromycin, Modafinil [7][citation needed], lamotrigine, nevirapine, Ibuprofen[8], ethosuximide, carbamazepine)[9][10], malignancy (carcinomas and lymphomas), or idiopathic factors (up to 50% of the time). SJS has also been consistently reported as an uncommon side effect of herbal supplements containing ginseng. SJS may also be caused by cocaine usage.[11]

Although Stevens Johnson Syndrome can be caused by viral infections, malignancies or severe allergic reactions to medication,the leading cause appears to be the inappropriate use of antibiotics and sulfa drugs. Medications that have traditionally been known to lead to Stevens Johnson Syndrome, Erythema Multiforme, Lyell's Syndrome, and Toxic Epidermal Necrolysis include sulfonamides (antibiotics), penicillins (antibiotics), barbiturates (sedatives), lamotrigine (anticonvulsant), and phenytoin - Dilantin (anticonvulsant). Combining lamotrigine with sodium valproate increases the risk of Stevens-Johnson Syndrome occurring.

Genetics

In East Asians the Carbamazepine and phenytoin induced syndrome is strongly associated with HLA-B75 (B*1502 allele of HLA-B).[12][13][14] A study in Europe suggested that the gene-marker is only relevant for East Asians.[15][16] Based on the Asian findings similar studies in Europe were performed, sixty-one percent of allopurinol-induced SJS/TEN carried the HLA-B58 (B*5801 allele - Phenotype frequency in Europeans is typically 3%), indicating that while the risk alleles differ between ethnicities, the HLA-B locus is strongly associated or closely linked to a strongly associated gene.[17]

Treatment

All medications should be discontinued, particularly those known to cause SJS reactions. Treatment is initially similar to that of patients with thermal burns, and continued care can only be supportive (e.g. IV fluids) and symptomatic (e.g. analgesic mouth rinse for mouth ulcer); there is no specific drug treatment (2002). Treatment with corticosteroids is controversial since it might aggravate the condition or increase risk of secondary infections. Other agents have been used, including cyclophosphamide and cyclosporine, but none have exhibited much therapeutic success. Intravenous immunoglobulin (IVIG) treatment has shown some promise in reducing the length of the reaction and improving symptoms. Other common supportive measures include the use of topical pain anesthetics and antiseptics, maintaining a warm environment, and intravenous analgesics. An ophthalmologist should be consulted immediately, as SJS frequently causes the formation of scar tissue inside the eyelids leading to corneal vascularization and impaired vision, as well as a host of other ocular problems. Also, an extensive physical therapy program ensues after the patient is discharged from the hospital.

Recent studies conducted by the Natural Therapies Research Board indicate pharmaceutical grade essential plant oils of Lavender, Birch, Eucalyptus, Geranium and Helichrysum exhibit therapeutic success and improve symptoms.

Prognosis

SJS proper (with less than 10% of body surface area involved) has the mortality rate of around 5%. The risk for death can be estimated using the SCORTEN scale, which takes a number of prognostic indicators into account.[11] Other outcomes include organ damage and blindness.

Eponym

It is named for Dr. Albert Mason Stevens and Dr. Frank Chambliss Johnson, American pediatricians who jointly published a description of the disorder in 1922.[18][19][20]
