Objective-To quantify the percentage of apoptotic peripheral blood neutrophils in systemic lupus erythematosus (SLE) and to determine the relations with disease activity and neutropenia. Methods-Neutrophil apoptosis in SLE patients (n =50) was assessed by flow cytometry using annexin V binding and fluorescent labelled anti-fas. Rheumatoid arthritis (RA, n =20) and inflammatory bowel disease patients (IBD, n =20) were studied as disease controls. Results-The percentage of apoptotic neutrophils, determined by annexin V binding, was increased in peripheral blood of SLE patients (median = 3.25%) compared with normal healthy donors (n =20, median = 1.20%) and disease controls (RA: median = 1.15%) (IBD: median =

Low-dose dietary supplementation with omega-3 fish oils in systemic lupus erythematosus not only has a therapeutic effect on disease activity but also improves endothelial function and reduces oxidative stress and may therefore confer cardiovascular benefits.

Joint disease in SLE is common and has a significant impact on patients in terms of their burden of disease and quality of life. Despite this it remains largely understudied in comparison with the other inflammatory arthropathies. Newer imaging techniques are challenging the traditional concepts of a non-erosive arthropathy that is outlined in the ACR diagnostic criteria for SLE. MRI and musculoskeletal US techniques have been applied extensively in RA to detail the underlying joint pathology, to monitor response to treatment and to guide prognosis. The advent of biological therapies has revolutionized the treatment of RA and has again been borne out of an abundance of research that exists surrounding the underlying pathobiological inflammatory pathways. Unfortunately, no such unified body of evidence exists for lupus arthritis, which has made the development of an appropriate classification system somewhat difficult as our understanding remains incomplete.

Musculoskeletal ultrasound could be utilized to enhance the delivery of undergraduate teaching in rheumatology.
