Overview
- The symptoms of SJS usually start within 2 months of starting a drug or other inciting trigger with symptoms such as red or reddish blue macules/papules on trunk and extremities and later increase in size and coalesce. Blisters/erosions/bullae and vesicles are seen later with confluent redness with skin sloughing. Most lesions heal rapidly within 1-3 weeks unless secondary bacterial infection of lesions occurs. Recovery can take longer, although it usually depends on the severity of symptoms and body surface area involved. Mortality rate is 1-5 percent in SJS and in TEN is 25-35 percent[1]
Natural History, Complications, and Prognosis
Natural History
- The symptoms of SJS usually start within 2 months of starting a drug or other inciting trigger with symptoms such as red or reddish blue macules/papules on trunk and extremities and later increase in size and coalesce.Blisters/erosions/bullae and vesicles are seen later with confluent redness with skin sloughing.
- Most lesions heal rapidly within 1-3 weeks unless secondary bacterial infection of lesions occurs.
- Recovery can take longer, although it usually depends on the severity of symptoms and body surface area involved
Complications
- Common complications of SJS/TEN include:
- Bacterial Infections leading to sepsis - more common in age>40, WBC>10,00, BSA more than or equal to 30 percent[2]
- Opthalmologic - Ranging from pain, photophobia, conjuctivitis to keratitis and endopthalmitis. Appropriate treatment of acute ocular complications can prevent long term complications[3]
- Pulmonary - Pnemonia, Interstitial pneumonitis, ARDS (25 percent of patients have been reported to require mechanical ventilation)[4]
- Skin - Scarring or hypertrophic changes
Prognosis[5]
- Prognosis and severity of SJS/TEN should be determined immediately after diagnosis to decide upon the appropriate medical management and setting.
- SCORTEN Severity of illness score may be used to determine the severity and prognosis
SCORTEN Parameter | Individual score | SCORTEN (sum of individual scores) | Predicted mortality (%) |
---|---|---|---|
Age > 40 years | Yes = 1, No = 0 | 0-1 | 3.2 |
Malignancy | Yes = 1, No = 0 | 2 | 12.1 |
Tachycardia (> 120/min) | Yes = 1, No = 0 | 3 | 35.8 |
Initial surface of epidermal detachment >10% | Yes = 1, No = 0 | 4 | 58.3 |
Serum urea >10 mmol/l | Yes = 1, No = 0 | >5 | 90 |
Serum glucose >14 mmol/l | Yes = 1, No = 0 | ||
Bicarbonate >20 mmol/l | Yes = 1, No = 0 |
- Patients with SCORTEN score of 0-1 with limited skin involvement can be manged in non-specialized wards[7]
- Patients with the SCORTEN score of 3 or more should be treated in an ICU.
- Depending on the extent of the skin sloughing/ Body surface are involved at the time of diagnosis, the prognosis may vary. However, the prognosis is generally regarded as good
- Mortality rate is 1-5 percent in SJS and in TEN is 25-35 percent[1]
- Mortality rate can be higher in elderly and those with extensive skin involvement
Negative Prognostic Factors:
- Hypernatremia
- Neutropenia
- Thrombocytopenia
- Increased BUN
