Abstract

The most important mitotic apparatus (MA) antigens are centrosome (CE), nuclear mitotic apparatus (NuMA-1, NuMA-2), midbody, and centromere F (CENP-F). We studied associations of anti-MA antibodies with other autoantibodies and their clinical significance. A total of 6270 patients were studied for the presence of anti-MA antibodies on HEp-2 cells. Sera positive for anti-MA were tested for anti-extractable nuclear antigens (ENA) antibodies. Anti-MA antibodies were detected in 56 (45 females and 11 males) of 6270 sera (0.9%). Of these 56, NuMA-1 was found in 23, NuMA-2 in 7, CE in 20, CENP-F in 5, and CENP-F/centrosome in 1 case. Anti-NuMA-1 were associated with anti-ENA antibodies (p < 0.001). Diagnoses were established in 43/56 patients: 22 connective tissue diseases, 7 infections, 6 autoimmune hepatitis, 3 vasculitis, 3 primary antiphospholipid syndrome, 1 malignancy, and 1 fever of unknown origin. The differential diagnosis of anti-NuMA-1-positive patients must include Sjögren’s syndrome, while patients with anti-CE antibodies must be observed for HCV infection.

Keynote webinar | Spotlight on medication adherence

Live: Thursday 27th June 2024, 18:00-19:30 (CEST)

WHO estimates that half of all patients worldwide are non-adherent to their prescribed medication. The consequences of poor adherence can be catastrophic, on both the individual and population level.

Join our expert panel to discover why you need to understand the drivers of non-adherence in your patients, and how you can optimize medication adherence in your clinics to drastically improve patient outcomes.
