The prognosis of two distinct clinical phenotypes of SLE-PAH
Author(s): Jieying Wang
Background: Based on the characteristics of systemic lupus erythematosus-associated pulmonary arterial hypertension (SLE-PAH), Sun et al has put forward a scoring system to distinguish two clinical phenotypes as vasculitic and vasculopathic subtypes. A weighted score ≥2 suggested a vasculitic subtype by combining two factors: The time interval between SLE and PAH diagnosis <2 years and ≥2 years were 1 and 0 point; SLE Disease Activity Index (SLEDAI) >9, 5-9 and <5 were 2, 1, 0 point, respectively. While the vasculitic subtype seemed to have poorer prognosis in Sun’s research, other study has shown controversial result.
