Rheumatoid vasculitis is a skin condition that is a typical feature of rheumatoid arthritis, presenting as peripheral vascular lesions that are localized purpura, cutaneous ulceration, and gangrene of the distal parts of the extremities. [1] [2]
Rheumatoid vasculitis may affect almost any organ in the body. The skin and peripheral nerves are the most frequently affected areas. Although major organ system involvement of the kidney, bowel, or heart is much less common, it can result in serious morbidity and mortality, such as renal failure, bowel ischemia, and myocardial infarction. [3] While the involvement of the central nervous system is uncommon, numerous case reports document its occurrence. [4] [5]
Rheumatoid vasculitis can cause palpable purpura, ulcers, nodules, and digital necrosis on the skin. [6] Even though it is nonspecific and present in many different disorders, livedo reticularis is frequently observed. [3]
Peripheral nervous system involvement is the second most common organ involved. Peripheral nervous system manifestations include distal symmetric sensory polyneuropathy, distal motor or combined neuropathy, and mononeuritis multiplex. [3]
Patients who have nodular rheumatoid arthritis that is seropositive are nearly exclusively affected by rheumatoid vasculitis. [7]
The patient's medical history and symptoms, physical examination, relevant laboratory tests, specialized testing (such nerve conduction studies), and tissue biopsy of the affected skin, muscle, nerves, or other organ are typically used to make the diagnosis.[ citation needed ]
Treatment options for mild cases of rheumatoid vasculitis affecting the skin or peripheral nerves include methotrexate or azathioprine combined with prednisone. More severe organ system involvement might need to be treated with biologic agents, cyclophosphamide, and higher doses of steroids. [3]
Psoriatic arthritis (PsA) is a long-term inflammatory arthritis that occurs in people affected by the autoimmune disease psoriasis. The classic feature of psoriatic arthritis is swelling of entire fingers and toes with a sausage-like appearance. This often happens in association with changes to the nails such as small depressions in the nail (pitting), thickening of the nails, and detachment of the nail from the nailbed. Skin changes consistent with psoriasis frequently occur before the onset of psoriatic arthritis but psoriatic arthritis can precede the rash in 15% of affected individuals. It is classified as a type of seronegative spondyloarthropathy.
Vasculitis is a group of disorders that destroy blood vessels by inflammation. Both arteries and veins are affected. Lymphangitis is sometimes considered a type of vasculitis. Vasculitis is primarily caused by leukocyte migration and resultant damage. Although both occur in vasculitis, inflammation of veins (phlebitis) or arteries (arteritis) on their own are separate entities.
Granulomatosis with polyangiitis (GPA), previously known as Wegener's granulomatosis (WG), after the German physician Friedrich Wegener, is a rare long-term systemic disorder that involves the formation of granulomas and inflammation of blood vessels (vasculitis). It is an autoimmune disease and a form of vasculitis that affects small- and medium-size vessels in many organs but most commonly affects the upper respiratory tract, lungs and kidneys. The signs and symptoms of GPA are highly varied and reflect which organs are supplied by the affected blood vessels. Typical signs and symptoms include nosebleeds, stuffy nose and crustiness of nasal secretions, and inflammation of the uveal layer of the eye. Damage to the heart, lungs and kidneys can be fatal.
Henoch–Schönlein purpura (HSP), also known as IgA vasculitis, is a disease of the skin, mucous membranes, and sometimes other organs that most commonly affects children. In the skin, the disease causes palpable purpura, often with joint pain and abdominal pain. With kidney involvement, there may be a loss of small amounts of blood and protein in the urine, but this usually goes unnoticed; in a small proportion of cases, the kidney involvement proceeds to chronic kidney disease. HSP is often preceded by an infection, such as a throat infection.
Polyarteritis nodosa (PAN) is a systemic necrotizing inflammation of blood vessels (vasculitis) affecting medium-sized muscular arteries, typically involving the arteries of the kidneys and other internal organs but generally sparing the lungs' circulation. Small aneurysms are strung like the beads of a rosary, therefore making this "rosary sign" an important diagnostic feature of the vasculitis. PAN is sometimes associated with infection by the hepatitis B or hepatitis C virus. The condition may be present in infants.
Cryoglobulinemia is a medical condition in which the blood contains large amounts of pathological cold sensitive antibodies called cryoglobulins – proteins that become insoluble at reduced temperatures. This should be contrasted with cold agglutinins, which cause agglutination of red blood cells.
Connective tissue disease, also known as connective tissue disorder, or collagen vascular diseases, refers to any disorder that affect the connective tissue. The body's structures are held together by connective tissues, consisting of two distinct proteins: elastin and collagen. Tendons, ligaments, skin, cartilage, bone, and blood vessels are all made of collagen. Skin and ligaments contain elastin. The proteins and the body's surrounding tissues may suffer damage when these connective tissues become inflamed.
Relapsing polychondritis is a systemic disease characterized by repeated episodes of inflammation and in some cases deterioration of cartilage. The disease can be life-threatening if the respiratory tract, heart valves, or blood vessels are affected. The exact mechanism is poorly understood.
Eosinophilic fasciitis, also known as Shulman's syndrome, is an inflammatory disease that affects the fascia, other connective tissues, surrounding muscles, blood vessels and nerves. Unlike other forms of fasciitis, eosinophilic fasciitis is typically self-limited and confined to the arms and legs, although it can require treatment with corticosteroids, and some cases are associated with aplastic anemia.
Mixed connective tissue disease (MCTD) is a systemic autoimmune disease that shares characteristics with at least two other systemic autoimmune diseases, including systemic sclerosis (Ssc), systemic lupus erythematosus (SLE), polymyositis/dermatomyositis (PM/DM), and rheumatoid arthritis. The idea behind the "mixed" disease is that this specific autoantibody is also present in other autoimmune diseases such as systemic lupus erythematosus, polymyositis, scleroderma, etc. MCTD was characterized as an individual disease in 1972 by Sharp et al., and the term was introduced by Leroy in 1980.
A rheumatoid nodule is a lump of tissue, or an area of swelling, that appears on the exterior of the skin usually around the olecranon or the interphalangeal joints, but can appear in other areas. There are four different types of rheumatoid nodules: subcutaneous rheumatoid nodules, cardiac nodules, pulmonary nodules, and central nervous systems nodules. These nodules occur almost exclusively in association with rheumatoid arthritis. Very rarely do rheumatoid nodules occur as rheumatoid nodulosis in the absence of rheumatoid arthritis. Rheumatoid nodules can also appear in areas of the body other than the skin. Less commonly they occur in the lining of the lungs or other internal organs. The occurrence of nodules in the lungs of miners exposed to silica dust was known as Caplan’s syndrome. Rarely, the nodules occur at diverse sites on body.
Palisaded neutrophilic and granulomatous dermatitis (PNGS) is usually associated with a well-defined connective tissue disease, lupus erythematosus or rheumatoid arthritis most commonly, and often presents with eroded or ulcerated symmetrically distributed umbilicated papules or nodules on the elbows.
Necrotizing vasculitis, also called systemic necrotizing vasculitis, is a general term for the inflammation of veins and arteries that develops into necrosis and narrows the vessels.
Cutaneous small-vessel vasculitis (CSVV) is inflammation of small blood vessels, usually accompanied by small lumps beneath the skin. The condition is also known as hypersensitivity vasculitis, cutaneous leukocytoclastic vasculitis, hypersensitivity angiitis, cutaneous leukocytoclastic angiitis, cutaneous necrotizing vasculitis and cutaneous necrotizing venulitis,
Livedoid vasculopathy (LV) is an uncommon thrombotic dermal vasculopathy that is characterized by excruciating, recurrent ulcers on the lower limbs. Livedo racemosa, along with painful ulceration in the distal regions of the lower extremities, is the characteristic clinical appearance. It heals to form porcelain-white, atrophic scars, also known as Atrophie blanche.
Rheumatoid neutrophilic dermatitis, also known as rheumatoid neutrophilic dermatosis, is a cutaneous condition associated with rheumatoid arthritis.
Rheumatoid nodulosis is a cutaneous condition associated with rheumatoid arthritis, characterized by the appearance of multiple nodules, most often on the hands.
Enteropathic arthropathy commonly referred to as enteropathic arthritis, is a type of arthritis linked to Crohn's disease, ulcerative colitis, and chronic inflammatory bowel diseases.
Lupus vasculitis is one of the secondary vasculitides that occurs in approximately 50% of patients with systemic lupus erythematosus (SLE).
Vasculitic neuropathy is a peripheral neuropathic disease. In a vasculitic neuropathy there is damage to the vessels that supply blood to the nerves. It can be as part of a systemic problem or can exist as a single-organ issue only affecting the peripheral nervous system (PNS). It is diagnosed with the use of electrophysiological testing, blood tests, nerve biopsy and clinical examination. It is a serious medical condition that can cause prolonged morbidity and disability and generally requires treatment. Treatment depends on the type but it is mostly with corticosteroids or immunomodulating therapies.
