Аннотация
BACKGROUND: Severe cutaneous adverse drug reactions (SCAR) are life-threatening and contain drug reactions with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and acute generalized exanthematous pustulosis (AGEP).
METHODS: We aimed to evaluate clinical features and prognostic factors for SCAR patients. From January 2010 to April 2022, 209 patients with SCAR (DRESS, n = 46, SJS/TEN, n = 128, AGEP, n = 35) were included in this study. Clinical symptoms, laboratory tests, causative drugs, disease courses, treatments, and outcomes were investigated.
RESULTS: Antibiotics ranked first (35.9 %) followed by traditional Chinese medicine (15.8 %) and antiepileptic drugs (14.8 %) among causative drugs of SCAR. One patient (2.2 %) with DRESS and seven patients (5.5 %) with SJS/TEN died in the hospital, while there was no AGEP-related mortality. The multivariate logistic regression analysis showed that high Registry of Severe Cutaneous Adverse Reactions score (OR = 2.340, 95 % CI = 1.192-4.591) and hemoglobin < 100 g/L (OR = 0.126, 95 % CI = 0.016-0.983) were independent risk factors of DRESS. Anemia (OR = 0.191, 95 % CI = 0.037-0.984) and body surface area detached involved at day 1 (OR = 2.749, 95 % CI = 1.115-6.778) were independent risk factors of SJS/TEN for severe acute complications and hospital death (P < 0.05). Lymphocytopenia (OR = 0.004, 95 % CI = 0.000-0.553) was a risk factor of AGEP for acute complications (P = 0.028).
CONCLUSION: This study reveals the clinical features and independent prognostic factors for SCAR, which may be helpful in the clinical management for SCAR patients.
