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.
The cause of PFAPA is unknown. [4] It is frequently discussed together with other periodic fever syndromes. [3] Possible causes include primarily genetic factors or it may be due to an initial infection. The condition appears to be the result of a disturbance of innate immunity. [5]
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; Other names: Familial Hibernian fever, Tumor necrosis factor receptor associated periodic syndrome: Specialty: Immunology: Symptoms: Vertigo, pericarditis [1] Causes: Mutations in the TNFRSF1A gene [2] Diagnostic method: Blood test, Genetic test [3] [4] Treatment: Corticosteroids, NSAIDS [1]
MKD is a periodic fever syndrome originally described in 1984 by the internist Jos van der Meer, [4] then at Leiden University Medical Centre. No more than 300 cases have been described worldwide. MKD was originally described as hyperimmunoglobulin D syndrome (HIDS), but HIDS is now recognized as a mild manifestation of MKD. [1]
The following is a list of genetic disorders and if known, type of mutation and for the chromosome involved. Although the parlance "disease-causing gene" is common, it is the occurrence of an abnormality in the parents that causes the impairment to develop within the child. There are over 6,000 known genetic disorders in humans.
