Periodic fever syndromes are a set of disorders characterized by recurrent episodes of systemic and organ-specific inflammation.Unlike autoimmune disorders such as systemic lupus erythematosus, in which the disease is caused by abnormalities of the adaptive immune system, people with autoinflammatory diseases do not produce autoantibodies or antigen-specific T or B cells.
Periodic fever, aphthous stomatitis, pharyngitis and adenitis syndrome is a medical condition, typically occurring in young children, in which high fever occurs periodically at intervals of about 3–5 weeks, frequently accompanied by aphthous-like ulcers, pharyngitis and cervical adenitis (cervical lymphadenopathy). The syndrome was described ...
Neonatal-onset multisystem inflammatory disease is a rare genetic periodic fever syndrome which causes uncontrolled inflammation in multiple parts of the body starting in the newborn period. Symptoms include skin rashes, severe arthritis, and chronic meningitis leading to neurologic damage. It is one of the cryopyrin-associated periodic syndromes.
The syndromes within CAPS overlap clinically, and patients may have features of more than one disorder. In a retrospective cohort of 136 CAPS patients with systemic involvement from 16 countries, [2] the most prevalent clinical features were fever (84% of cases, often with concurrent constitutional symptoms such as fatigue, malaise, mood disorders or failure to thrive), skin rash (either ...
Familial Mediterranean fever (FMF) is a hereditary inflammatory disorder. [ 1 ] : 149 FMF is an autoinflammatory disease caused by mutations in the Mediterranean fever (MEFV) gene, which encodes a 781–amino acid protein called pyrin . [ 2 ]
TNF receptor associated periodic syndrome (TRAPS [5]) is a periodic fever syndrome associated with mutations in a receptor for the molecule tumor necrosis factor (TNF) that is inheritable in an autosomal dominant manner. Individuals with TRAPS have episodic symptoms such as recurrent high fevers, rash, abdominal pain, joint/muscle aches and ...
These responses are characterized by periodic or chronic systemic inflammation, usually without the involvement of adaptive immunity. Autoinflammatory diseases are a separate class from autoimmune diseases; however, both are characterized by an immune system malfunction that may cause similar symptoms, such as rash, swelling or fatigue. However ...
Periodic paralysis is an autosomal dominant myopathy with considerable variation in penetrance, leading to a spectrum of familial phenotypes (only one parent needs to carry the gene mutation to affect the children, but not all family members who share the gene are affected to the same degree). Specific diseases include: [citation needed]
