The objective of the study is to investigate the mechanisms of cyclophosphamide sequential therapy for patient with primary Sjögren's syndrome-associated interstitial lung disease (PSS-ILD).
In 20% of cases, ILD can be diagnosed before pSS; anyway, few studies have investigated the frequency of ILD as the first clinically relevant manifestation of pSS, generally referred to retrospective studies.
The objective of the study was to assess the ESSDAI index characteristics in the SJÖGRENSER cohort (Spanish Rheumatology Association's registry of patients with Primary Sjögren Syndrome [PSS]).
The molecules under current clinical development for pSS target B cells (n = 4), T cells or T/B cells costimulation (n = 5), inflammatory cytokines or chemokines and their receptors (n = 5), intracellular signalling pathways (n = 7) and various other targets identified in pSS (n = 4).
