Lupus & antiphospholipid syndrome

Visceral fat, cardiovascular risk factors and quality of life in lupus activity categorised via complement C3

Lupus Sci MedPublished Cross-sectional study

Authors' conclusion

Inactive patients with SLE exhibited more adverse cardiovascular risk markers compared with active patients categorised by complement C3, even when glucocorticoid administration was accounted for.
