    • "The response to the IL-1 receptor antagonist (IL-1Ra) anakinra in both cases, suggests involvement of IL-1 in neuropathic pain and pancreatitis, respectively. Other incidentally reported symptoms include pseudoxanthoma elasticum [60,90,144], headache, vertigo and depression [60] , and severe thrombophilia with antiphospholipid syndrome and hyperhomocysteinemia [51]. The family history is typically negative for the symptoms of SchS. "
    [Show abstract] [Hide abstract] ABSTRACT: Schnitzler's syndrome is an autoinflammatory disorder characterized by the association of a monoclonal IgM (or IgG) gammopathy, a chronic urticarial rash, and signs and symptoms of systemic inflammation, including fever, arthralgias and bone pain. It was first described in 1972. This review summarizes the clinical features, efficacy of therapies, and follow-up data of the 281 cases that have been reported to date. Also, the results of skin histology, bone imaging, laboratory investigations, and studies of the pathogenesis will be discussed, including the pivotal role of interleukin-1 beta in this disorder.

  • [Show abstract] [Hide abstract] ABSTRACT: The list of multisystem diseases involving both kidney and skin is long and includes immunologic disorders like systemic lupus erythematodes, a broad variety of vasculitides, metabolic disorders like diabetes mellitus, and infectious diseases. The present work describes the first case of renal failure due to Schnitzler's syndrome, a rare entity characterized by the association of generalized chronic urticaria, monoclonal IgM gammopathy, and osteosclerotic lesions. The described patient experiences improvement of renal function after treatment with the chimeric anti-CD20 antibody rituximab, indicating that the impairment of renal function might be mediated by B-lymphocytes. Renal insufficiency is known to be a potential complication of hypocomplementemic urticarial vasculitis. The present case reveals that it can occur in normocomplementemic urticarial vasculitides as well. Schnitzler's syndrome is a rare but probably underdiagnosed syndrome. It should be considered in the differential diagnosis of rash and coincidental renal failure of unknown origin. Immunofixation of immunoglobulins constitutes the crucial diagnostic step, since monoclonal gammopathy is a constant clinical sign in this entity.

  • [Show abstract] [Hide abstract] ABSTRACT: Schnitzler syndrome is a rare disorder characterized by a chronic urticarial rash and monoclonal gammopathy, accompanied by intermittent fever, arthralgia or arthritis, bone pain, and lymphadenopathy. Our objectives are to systematically review disease characteristics of Schnitzler syndrome and collect follow-up information to gain insight into treatment efficacy and long-term prognosis. PubMed and MEDLINE databases (1966-2006) were searched, using the key words "Schnitzler syndrome," and the combination of "urticaria" with "monoclonal gammopathy," "immunoglobulin M (IgM)," or "paraproteinemia," as well as secondary references. Data on a total of 94 patients who met the criteria for Schnitzler syndrome were reviewed. Questionnaires sent to all authors retrieved additional follow-up data on 43 patients, resulting in a mean follow-up of 9.5 years after onset of symptoms, and a follow-up of 20 years or more in 10 patients. Symptoms, signs, and laboratory findings as found in the 94 patients are reviewed in detail. There have been promising developments in therapeutic options, especially antiinterleukin-1 treatment, which induced complete remission in all 8 patients treated so far. To date, no spontaneous complete remissions have been reported. Patients with Schnitzler syndrome showed no increased mortality during the present follow-up. However, they had a 10-year risk of 15% of developing a lymphoproliferative disorder, most notably Waldenström's macroglobulinemia. Three cases of type amyloid A (AA) amyloidosis associated with Schnitzler syndrome were reported. Schnitzler syndrome is a disabling disorder which affects multiple systems and which can be considered as an autoinflammatory syndrome. There are new, effective treatment options, but close monitoring remains warranted because of the increased risk of lymphoproliferative disease.
