- Results are presented as number and percent of patients unless otherwise stated. aResulting in an intensification of the immunosuppressive therapy (> 50mg prednisone-equivalent added, or switch of the therapy regimen to a more potent regimen, such as cyclophosphamide). AZA, azathioprine; MMF, mycophenolate mophetil; IS, immunosuppression; CRF, chronic renal failure; CNS, central nervous system; ILD, interstitial lung disease; APLA, anti-phospholipid antibodies; LA, lupus anticoagulant; SLEDAI, SLE disease activity index. bData incomplete (antibody status known in 37 and 32 patients respectively). Statistically significant differences detected between the dose of prednisone-equivalent, Dunn's Multiple Comparison test: #P < 0.05, ##P < 0.01, ###P < 0.001 statistically significant differences between patients taking MMF compared to patients without immunosuppressive therapy (no IS). §P < 0.05, §§P < 0.01, §§§P < 0.001 for statistically significant differences between patients taking AZA compared to patients without immunosuppressive therapy.
