High levels of rheumatoid factor (in general, above 20 IU/mL, 1:40, or over the 95th percentile; there is some variation among labs) occur in rheumatoid arthritis (present in 80%) and Sjögren's syndrome (present in 50-70% of primary forms of disease). [11] The higher the level of RF the greater the probability of destructive articular disease.
RS3PE typically involves the joints of the extremities, specifically the metacarpophalangeal and proximal interphalangeal joints, wrists, shoulders, elbows, knees and ankles. [4] It is more common in older adults, with the mean age between 70 and 80 years in most studies. [4] [5] It occurs more often in men than in women with a 2:1 ratio.
Rheumatism [2] /ˈruməˌtɪzəm/ or rheumatic disorders are conditions causing chronic, often intermittent pain affecting the joints or connective tissue. [3] Rheumatism does not designate any specific disorder, but covers at least 200 different conditions, including arthritis and "non-articular rheumatism", also known as "regional pain syndrome" or "soft tissue rheumatism".

ACR score is a scale to measure change in rheumatoid arthritis symptoms. [1] It is named after the American College of Rheumatology. The ACR score is more often used in clinical trials than in doctor patient-relationships, as it allows a common standard between researchers. Different degrees of improvement are referred to as ACR20, ACR50, ACR70.
The biologic agent rituximab (anti-B cell therapy) is now licensed for use in refractory rheumatoid arthritis. [9] Physiotherapy is vital in the treatment of many rheumatological disorders. Occupational therapy can help patients find alternative ways for common movements that would otherwise be restricted by their disease.
Detection of autoantibodies against mutated citrullinated vimentin is part of rheumatoid arthritis (RA) diagnostics, especially in sera negative for rheumatoid factor (RF negative sera). Anti-MCV antibodies are a member of the ACPA family, a group of the so-called a ntibodies to c itrullinated p rotein/peptide a ntigens.
