Treatment of Stevens-Johnson Syndrome
Immediately discontinue all suspected culprit medications and transfer patients with >10% body surface area epidermal detachment to a specialized burn center or ICU within hours of diagnosis—this is the single most critical intervention that directly impacts survival. 1, 2
Immediate Life-Saving Actions
- Calculate SCORTEN within the first 24 hours to predict mortality risk (scores 0-7 correspond to mortality rates of approximately 1-99%) and guide intensity of care 3, 1, 2
- Arrange mandatory ophthalmology consultation within 24 hours of diagnosis, as failure to do so is associated with permanent visual impairment 1, 2
- Document all medications taken in the preceding 2 months, including over-the-counter and herbal products, with exact start dates 3, 1
- Common culprit drugs include allopurinol, carbamazepine, lamotrigine, nevirapine, oxicam NSAIDs, phenobarbital, phenytoin, sulfamethoxazole, and sulfasalazine 3
Specialized Care Environment
- Admit patients to a burn center or ICU staffed by a multidisciplinary team including dermatology, intensive care, ophthalmology, and specialist skincare nursing 3, 1, 2
- Provide barrier nursing in a temperature-controlled room (25-28°C) on a pressure-relieving mattress to prevent hypothermia and reduce infection risk 1, 2
- Early transfer to specialized centers reduces mortality; delayed transfer significantly increases death rates 3, 1, 2
Fluid and Nutritional Management
- Establish adequate intravenous fluid replacement guided by urine output and hemodynamic parameters, but avoid overaggressive resuscitation that causes pulmonary, cutaneous, and intestinal edema 1, 2
- Monitor fluid balance regularly using vital signs, urine output, and electrolyte measurements 1
- Provide continuous enteral nutrition delivering 20-25 kcal/kg/day during the catabolic phase, increasing to 25-30 kcal/kg/day during recovery 1
- Use nasogastric feeding when oral intake is impossible due to buccal mucositis 1
Skin and Wound Care
- Handle skin with extreme gentleness using anti-shear techniques to minimize further epidermal detachment 1, 2
- Leave detached epidermis in situ to act as a biological dressing—do not debride intact blisters 1, 2
- Cleanse wounds gently by irrigating with warmed sterile water, saline, or dilute chlorhexidine (1:5000) 1
- Apply greasy emollient (50% white soft paraffin with 50% liquid paraffin) over the entire epidermis, including denuded areas, every 2-4 hours 1, 2
- Cover denuded dermis with non-adherent dressings (e.g., Mepitel or Telfa) and secondary foam or burn dressings to collect exudate 1
- Apply silver-containing dressings only to sloughy areas 1
- Reserve surgical debridement with biosynthetic xenograft or allograft for clinical deterioration, extension of detachment, local sepsis, delayed healing, or wound conversion 1
Infection Prevention and Management
Do not use prophylactic systemic antibiotics—indiscriminate administration increases skin colonization with resistant organisms, particularly Candida, without improving outcomes. 1, 2
- Obtain bacterial and candidal swabs from three lesional sites on alternate days for culture 1, 2
- Monitor for clinical infection signs: confusion, hypotension, oliguria, desaturation, increased skin pain, rising C-reactive protein, and neutrophilia 1
- Initiate targeted antimicrobial therapy only when clinical signs of infection are present 1, 2
- Consider herpes simplex virus reactivation in slowly healing eroded or vesicular areas, particularly genital and oral sites 1
Mucosal Management
Ophthalmologic Care
- Perform ophthalmology examination within 24 hours of diagnosis and repeat daily throughout the acute phase 1, 2
- Apply preservative-free lubricating eye drops every 2 hours during the acute illness 1, 2
- Conduct daily ocular hygiene by an ophthalmologist or trained nurse to remove debris and break conjunctival adhesions 1
- Use topical antibiotics when corneal fluorescein staining or ulceration is present 1
- Apply topical corticosteroid eye drops under ophthalmology supervision to reduce ocular surface damage 1
Oral Care
- Apply white soft paraffin ointment to the lips immediately and then every 2 hours throughout the acute phase 1, 2
- Use anti-inflammatory oral rinse containing benzydamine hydrochloride every 3 hours, especially before meals 1
- Perform antiseptic oral rinse twice daily to lower bacterial colonization 1
- Provide topical anesthetic (viscous lidocaine 2% or cocaine mouthwash 2-5%) for severe oral discomfort 1
- Apply topical corticosteroids to oral mucosa as needed 1
Urogenital Care
- Insert urinary catheter when urogenital involvement causes dysuria, retention, or when accurate output monitoring is required 1
- Apply white soft paraffin ointment to urogenital skin and mucosa every 4 hours 1
- Use vaginal dilators or tampons wrapped in Mepitel to prevent vaginal synechiae formation 1
Pain Management
- Provide baseline non-opioid analgesia for comfort at rest 1
- Add opioid analgesia for breakthrough pain 1
- Consider patient-controlled analgesia where appropriate 4
- Consider sedation or general anesthesia for patient handling, repositioning, and dressing changes 4
Systemic Immunomodulatory Therapy
Cyclosporine 3 mg/kg daily for 10 days (tapered over 1 month) has shown the most consistent benefit with reduced mortality compared to predicted rates in multiple studies. 1, 2
- If using corticosteroids, initiate intravenous methylprednisolone 0.5-1 mg/kg (or equivalent) within 72 hours of disease onset, then switch to oral corticosteroids with a taper lasting at least 4 weeks 1, 2
- For immune-checkpoint-inhibitor-induced SJS/TEN, use methylprednisolone 1-2 mg/kg for grade 4 disease or 0.5-1 mg/kg for grade 3 disease 1
- Evidence for IVIG is equivocal—pooled analysis showed no mortality benefit (OR 1.00,95% CI 0.58-1.75) 1, 5
- Thalidomide should be avoided as it was associated with excess deaths in a randomized trial 1, 6
Additional Supportive Measures
- Administer low-molecular-weight heparin as prophylactic anticoagulation for immobile patients 1
- Provide proton-pump inhibitor when enteral nutrition cannot be established 1
- Consider recombinant human G-CSF for neutropenic patients 1
Discharge Planning and Follow-Up
- Provide written information about the culprit drug(s) and any cross-reactive medications to avoid 1, 2
- Advise patients to wear a MedicAlert bracelet naming the culprit drug 1, 2
- Document the drug allergy in the medical record and inform all healthcare providers 1, 2
- Report the adverse drug reaction to national pharmacovigilance authorities 1, 2
- Inform patients that fatigue and lethargy may persist for several weeks after discharge 1
- Schedule ophthalmology follow-up to monitor for chronic ocular complications, as 50-63% develop late complications including severe dry eyes and trichiasis 2
Critical Pitfalls to Avoid
- Delayed transfer to specialized care significantly increases mortality 1, 2
- Continued use of the culprit medication worsens the condition and increases mortality 1
- Failure to involve ophthalmology within 24 hours leads to permanent visual impairment 1
- Overaggressive fluid resuscitation causes pulmonary, cutaneous, and intestinal edema 1
- Indiscriminate prophylactic antibiotics increase resistant organism colonization without benefit 1, 2
