BACKGROUND: Small case series and case reports indicated that atypical persistent pruritic eruptions (PPEs), another type of skin lesions seen in adult-onset Still's disease (AOSD), imply a worse prognosis than typical evanescent rashes.
OBJECTIVE: To investigate clinical characteristics and macrophage activation syndrome (MAS) occurrence in AOSD with PPEs.
METHODS: A retrospective cohort study analyzed 150 patients with AOSD with rashes at the First Affiliated Hospital of Zhejiang University from January 2013 to December 2019.
RESULTS: Patients with AOSD with PPEs had higher lactate dehydrogenase (492.00 U/L vs 382.00 U/L; P < .001) and ferritin (6944.10 ng/ml vs 4286.60 ng/ml; P = .033), and lower fibrinogen (5.05 g/L vs 5.77 g/L; P = .014) than those with evanescent rashes. Patients with AOSD with PPEs had a higher incidence (17.4% vs 3.1%, P = .006) and cumulative event rate for MAS (P = .008) and tended to receive high-dose glucocorticoid (36% vs 20.3%; P = .036). Multivariate analysis indicated that PPEs (hazard ratio [HR], 5.519; 95% confidence interval [CI], 1.138-26.767; P = .034), aspartate aminotransferase of greater than 120 U/L (HR, 8.084; 95% CI, 1.728-37.826; P = .008), and splenomegaly (HR, 21.152; 95% CI, 2.263-197.711; P = .007) were independent risk factors for MAS.
LIMITATIONS: Single-center, retrospective nature, small sample size.
CONCLUSION: PPEs indicated increased severity and MAS occurrence versus evanescent rashes. PPEs, aspartate aminotransferase of greater than 120 U/L, and splenomegaly were risk factors for MAS in AOSD with skin involvement.
