HOOK

Prompt recognition and treatment of severe skin reactions can be lifesaving. While Erythema multiforme and Stevens-Johnson syndrome can share some clinical features, they are distinct conditions with different causes, severity, and treatment approaches. Stevens-Johnson syndrome (SJS) is a medical emergency that requires immediate evaluation and specialized care.

OVERVIEW

Erythema Multiforme (EM)

• Often triggered by infections, particularly Herpes simplex

• Usually presents with characteristic "target" lesions

• Most cases are self-limited and less severe than SJS

Stevens-Johnson Syndrome (SJS)

• Most commonly triggered by medications, though infections may also contribute

• Involves widespread skin and mucous membrane damage

• May require treatment in an intensive care unit or specialized burn center

TREATMENT APPROACHES

For Erythema Multiforme

✔ Identify and treat the underlying trigger✔ Symptom relief with pain management and skin care✔ Topical corticosteroids may be used for localized symptoms in selected patients✔ Antiviral therapy may be considered for recurrent EM associated with herpes simplex infection✔ Maintain hydration and monitor for complications

For Stevens-Johnson Syndrome

✔ Immediate discontinuation of the suspected causative medication✔ Hospitalization with intensive supportive care✔ Careful fluid and electrolyte replacement✔ Specialized wound and skin care✔ Pain management and nutritional support✔ Eye, oral, and genital care when mucous membranes are involved✔ Consultation with dermatology, ophthalmology, and other specialists as needed

ADVANCED TREATMENT OPTIONS

Depending on the patient's condition and specialist assessment, treatment may include:

• Immunomodulatory therapies in selected cases

• Careful infection prevention and treatment if secondary infections develop

• Respiratory support if airway involvement occurs

• Long-term rehabilitation and follow-up for patients with significant complications

The use of medications such as systemic corticosteroids or other immunomodulatory agents remains individualized and should be guided by specialists, as recommendations vary based on the patient's condition and available evidence.

BENEFITS OF EARLY DIAGNOSIS

✔ Reduces the risk of serious complications✔ Enables rapid removal of the triggering medication when applicable✔ Improves symptom management and supportive care✔ Helps preserve skin, eye, and mucosal function✔ Can improve overall outcomes, particularly in SJS

PATIENT CARE TIPS

• Seek immediate medical attention if a widespread rash is accompanied by fever, blistering, mouth sores, or eye involvement.

• Never restart a medication suspected of causing SJS or a severe drug reaction unless specifically advised by a healthcare professional.

• Inform all future healthcare providers about any previous severe drug reactions.

• Attend recommended follow-up appointments, particularly if the eyes or other mucous membranes were affected.

ENGAGEMENT QUESTION

Which advancement do you think could have the greatest impact on improving outcomes in severe skin reactions: earlier diagnosis, personalized medicine to predict drug reactions, improved supportive care, or new targeted immunotherapies?
