[Tumor necrosis factor receptor superfamily 1A-associated periodic syndrome (TRAPS)].
OBJECTIVE
Tumor necrosis factor receptor superfamily 1A associated periodic syndrome (TRAPS) belongs to the group of hereditary fever syndromes, also called hereditary auto-inflammatory syndromes.


BACKGROUND
The diagnosis of TRAPS should be evoked in presence of the following clinical signs, whatever the population of the affected patients. TRAPS acute inflammatory access, of 1 to 3 weeks' duration, is characterised by the presence of fever, abdominal pain, myalgias, various types of skin rash including erysepela-like erythema. Long term inflammatory response can lead to AA amyloidosis. Genetic testing will confirm the diagnosis when showing a mutation in the extracellular part of the TNFRSF1A receptor. Therapeutic management of TRAPS is not definitely established. Daily colchicine does not seem to prevent efficiently inflammatory attacks. Corticosteroids, in contrast can attenuate the intensity and diminish the duration of attacks.


CONCLUSIONS
The value of biological agents that inhibits TNF action is not yet completely determined in TRAPS. Mechanisms of the disease are not yet elucidated. In some families with specific mutations, a relative soluble TNF receptor deficiency has been found in the plasma. However this mechanism does not account for what is observed in other kindreds.
