【定义】本病又名发作性多浆膜炎、家族性复发性多浆膜炎或周期热,为一以急性自限性发热合并腹腹炎、胸膜炎和关节炎为特征的遗传病。病情发作间隔不规律,也不能预期,故非真正的周期性。【病因】病因不明。鉴于精神应激可能诱使发作,很多病人又都有继发性精神异常,因此使人想到精神因素可能为其主要病因,但尚无充分证明。 [Definition] The disease, also known as episodic polyserositis, familial recurrent polyserositis or periodic fever, is an inherited condition characterized by acute, self-limited fever combined with abdominal, pleurisy and arthritis. Irregular episodes of illness, can not expect, it is not a real cyclical. Etiology etiology is unknown. In view of the fact that mental stress may induce seizures and that many patients have secondary mental abnormalities, it is tempting to think that mental factors may be the major cause of the seizures, but this is not yet fully substantiated.
