Double plasma molecular adsorption system for Stevens–Johnson syndrome/toxic epidermal necrolysis: A case report

Abstract

BACKGROUND Stevens–Johnson syndrome and toxic epidermal necrolysis (SJS/TEN) are very serious skin allergies, with an etiology related to infections and medication. Since the coronavirus disease 2019 (COVID-19) pandemic, severe acute respiratory syndrome coronavirus-2 has also been considered to cause SJS/TEN. CASE SUMMARY We report the case of a woman in her thirties who took acetaminophen after contracting COVID-19. After 3 d of fever relief, she experienced high fever and presented with SJS/TEN symptoms, accompanied by intrahepatic cholestasis. Three days of corticosteroid treatment did not alleviate the skin damage; therefore, double plasma molecular adsorption system (DPMAS) therapy was initiated, with treatment intervals of 48 h. Her skin symptoms improved gradually and were resolved after seven DPMAS treatments. CONCLUSION DPMAS therapy is beneficial for abrogating SJS/TEN because plasma adsorption and perfusion techniques reduce the inflammatory mediators (e.g. , tumor necrosis factor-alpha and interleukin-10 and-12) speculated to be involved in the pathology of the skin conditions.
