Rheumatological diseases

Osteoarthritis (OA) is by far the most common rheumatological disease; at an advanced age, almost everyone is affected by the disease.

Ankylosing spondylitis (AS) is a chronic inflammatory disease of the axial skeleton that manifests itself with deep-seated pain at night or early in the morning (lumbar spine, buttocks) and morning stiffness.

Polymyalgia rheumatica (PMR, polymyalgia) is an inflammatory rheumatic disease that is often associated with giant cell arteritis (arteritis temporalis).

Psoriatic arthritis (PsA) is a chronic inflammatory joint disease associated with psoriasis of the skin and/or nails.

It describes an "arthritis that occurs shortly after an infection at another site in the organism, but in which the microorganisms cannot be isolated from the joint".

SLE is a complex, systemic autoimmune disease with a variable course that can be associated with potentially life-threatening involvement of internal organs.

Vasculitis is a disease in which autoimmunological processes lead to inflammation of arteries, arterioles, capillaries, venules and veins.

Systemic sclerosis is a multisystem disease characterised by inflammatory processes, fibrosis of the skin and internal organs and a generalised vasculopathy.
