Up until about 2005, the urticarial eruption of Schnitzler syndrome was typically resistant to treatment. No treatment was consistently effective.
Nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and immunosuppressive agents have been reported to provide variable relief from the symptoms of bone pain and arthralgias associated with Schnitzler syndrome.
Skin and extracutaneous manifestations respond poorly to H1 and H2 antihistamines. Colchicine and dapsone have been tried with variable success in different patients. A few patients were responsive to treatment with thalidomide but the occurrence of peripheral neuropathy limits its use.[13, 14] Rituximab, an anti-CD20 monoclonal antibody, was reported to be effective in one patient[15] but unsuccessful in another.[16] Reports of using chloroquine, chlorambucil, cyclophosphamide, azathioprine, plasmapheresis, and high-dose intravenous immunoglobulin have indicated no response. Psoralen plus UV light (PUVA) may reduce the intensity of the rash in some patients.
NSAIDs have proved to be of some benefit for the bone pain and fever, but not for the urticaria. Systemic steroids may be somewhat effective at controlling the cutaneous eruption, but usually at doses that can cause significant long-term adverse effects.
Pefloxacin mesylate administered at a dose of 800 mg/d may be a therapeutic option. In a case series of 11 patients, it was shown to significantly reduce the intensity and frequency of many of the manifestations in a majority of the group, and it provided a steroid-sparing effect for some patients being treated with systemic corticosteroids.[3] It was less active on the osteoarticular component of Schnitzler syndrome.
Anakinra, a recombinant form of the naturally occurring IL-1 receptor antagonist, and rilonacept, a dimeric fusion protein that acts as a decoy IL-1 receptor, are two agents with recently reported benefit in Schnitzler syndrome.[17]
