J Rheumatol. 2019 Nov;46(11):1535-1539. doi: 10.3899/jrheum.181204. Epub 2019 Mar 15.

Abstract

Objective: To describe a new autoinflammatory syndrome with recurrent fever and monoclonal gammopathy that differs from Schnitzler syndrome.

Methods: We conducted a retrospective study of patients with monoclonal gammopathy and recurrent fever of unknown origin.

Results: Five patients were studied; median age at onset of symptoms was 44 years. Median frequency of fever attacks was 6 episodes per year. In the absence of treatment, the median duration of fevers was 3 days.

Conclusion: This new autoinflammatory syndrome is defined by an association among monoclonal gammopathy, arthralgias, and recurrent fever.

Keywords: INNATE IMMUNE RESPONSE; PARAPROTEINEMIAS; SCHNITZLER SYNDROME.
