Stevens-Johnson syndrome

Stevens-Johnson syndrome is a severe condition characterized by the destruction and detachment of the skin epithelium and mucous membranes, involving less than 10% of the body surface area. It is considered a limited form of toxic epidermal necrolysis and is often triggered by adverse reactions to medications or infections rather than inherited genetic factors. The precise genetic basis is not well defined, and prevalence data remains unknown. The condition can affect individuals of various age groups, and its onset is typically acute.

Clinically, Stevens-Johnson syndrome presents with a rapid onset of flu-like symptoms, followed by painful red or purplish skin lesions that progress to blistering and epidermal detachment. Mucosal surfaces such as the eyes, mouth, and genitals are commonly involved, resulting in erosions and ulcerations. Not all individuals experience all features, and severity varies considerably. Early recognition of the skin and mucous membrane involvement is critical for prompt medical intervention.

The precise genetic basis of Stevens-Johnson syndrome is not well established, and it is thought to result from complex interactions between genetic predisposition and environmental triggers such as medications or infections. Since no specific genes or inheritance patterns have been identified for this condition, the focus is on understanding the immunologic reactions that lead to epidermal damage. This means that, rather than being directly inherited, the syndrome is typically an unpredictable adverse reaction.

Currently, management focuses on supportive care and symptom relief, with treatment tailored to the individual. Patients are often cared for in specialized settings such as burn units or intensive care, where multidisciplinary teams including dermatologists, ophthalmologists, and critical care specialists manage complications. Supportive care strategies include fluid balance, pain control, and meticulous wound care to prevent infections. It is important for patients to discuss treatment options with their healthcare team to determine the most appropriate approach for their specific situation.

The course of Stevens-Johnson syndrome is highly variable, with outcomes depending on factors such as the extent of tissue involvement and the timeliness of medical intervention. Many individuals experience recovery with minimal long-term effects, although some may have persistent complications, especially involving the eyes or skin. Outcomes described in medical literature continue to evolve as standards of care improve. Families are encouraged to connect with specialists experienced in managing this condition, and genetic counseling may offer further guidance regarding potential risk factors.

Several clinical trials are currently investigating new treatment approaches for Stevens-Johnson syndrome. Active research in this area continues to explore ways to improve outcomes and reduce complications associated with the condition.
