چکیده

IL-1 receptor antagonist anakinra is usually highly efficient in Schnitzler syndrome (SS), a rare inflammatory condition associating urticaria, fever, and IgM monoclonal gammopathy. In this study, we aimed to assess lipopolysaccharide (LPS)-induced production of inflammatory cytokines by peripheral blood mononuclear cells (PBMCs) before and after 1 month of anakinra in patients with SS. LPS-induced production of IL-1β, IL-6 and TNFα was assessed by enzyme-linked immunosorbent assay with and without anakinra in vitro, and before and after 1 month (in vivo condition) of treatment in 2 patients with SS. Spontaneous production of IL-1β, IL-6 and TNF-α by PBMCs was similar in the patients and the healthy controls and was almost undetectable. Stimulation with LPS caused a higher release of cytokines from the patients than from the healthy controls. Before in vivo anakinra start, in vitro adjunction of anakinra reduced the high LPS-induced production of IL-1β and TNFα in both patients and of IL-6 in one patient. After 1 month of treatment with anakinra, while the patients had dramatically improved, there was also a marked reduction in LPS-induced cytokines production, which was almost normalized in one patient. This study shows an abnormal LPS-induced inflammatory cytokines production in SS, which can be decreased or even normalized by in vitro and in vivo anakinra.

Schnitzler Syndrome: A Dramatic Response to Anakinra

Schnitzler syndrome is a rare acquired systemic disease with a chronic evolution and difficult treatment. We report a 50-year-old woman with Schnitzler syndrome for 10 years, with major impact on her quality of life and refractory to conventional therapies. The patient was started on anakinra, an IL-1 receptor antagonist, with a rapid and sustained remission of the syndrome manifestations.

Long-term control of refractory Schnitzler syndrome with anakinra: a case report

Schnitzler syndrome is a rare inflammatory disorder characterized by chronic urticarial rash, monoclonal gammopathy, periodic fever, arthralgia/arthritis and bone pain. However, the results of management of Schnitzler syndrome are often disappointing and its treatment remains a challenge. No cases of spontaneous complete remission have been reported. Anakinra is an interleukin 1 receptor antago...
