스티븐스 존슨 증후군 및 독성표피괴사융해증 88예의 임상적 고찰

Abstract

Background: Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are potentially fatal acute hypersensitivity reactions that involve the skin and mucous membranes. Because they are relatively rare diseases, it is difficult to obtain well-organized epidemiological data. The clinicodemographic characteristics, culprit drugs, and factors related to disease prognosis may vary. Objective: To identify the characteristics of SJS/TEN by investigating patient clinicopathological characteristics, laboratory findings, suspected drugs, and mortality through a retrospective study using medical record data. Methods: The clinical records of patients diagnosed with SJS/TEN between February 2009 and February 2019 at three medical institutions of Soonchunhyang University were retrospectively reviewed. Data pertaining to sex, age, history, suspected drugs, latent period, laboratory findings, and mortality were collected, and their correlations were analyzed. Results: We identified SJS/TEN in 88 patients. Among the probable causative agents, antibiotics were the most common (29 cases, 33.0%), followed by nonsteroidal anti-inflammatory drugs (NSAIDs) in 20 cases (22.7%). The period between drug administration and symptom onset varied with the causative agent. Patients who died had high SCORTEN scores. In addition, hypertension, diabetes, renal failure, and cardiac disease had a statistically significant association with high SCORTEN. Conclusion: Antibiotics, NSAIDs, antiepileptics and allopurinol were the most commonly implicated drugs in our retrospective study. There was a significant correlation between comorbidities. Because SJS/TEN is a life-threatening condition, early recognition of the suspected drug are important. The results of this study may provide insights that aid in the early diagnosis and prediction of disease outcomes of SJS/TEN in the Korean population.
