Schnitzler syndrome diagnostic criteria

Inclusion criteria included a diagnosis of SchS (Strasbourg criteria). All available bone scans were reviewed and scored according to the intensity and number of pathological sites Diagnostic criteria for the Schnitzler syndrome * Associated findings included pseudoxanthum elasticum in 2 patients (29, 49) , peripheral neuropathy with the presence of monoclonal IgM with anti-MAG (myelin-associated glycoprotein) in 1 patient (25) , C4 deficiency in 2 patients (39) , and nodular regenerative hyperplasia of the liver in 1 patient (24) . We compare clinical and histopathological findings for both diseases and, as this patient meets two of the six existing diagnostic criteria for adult onset Still's disease, we propose that Schnitzler's syndrome is an important entity to be added to the list of differential diagnoses for adult onset Still's disease. 2021-03-10 · Purpose of ReviewWe focus on recent advances in diagnosis and therapeutic strategies, as well as on pathogenesis of Schnitzler syndrome.Recent FindingsNew diagnostic criteria were established, and their external validity was assessed in a retrospective cohort study. Dr David Khan has kindly provided a thoughtful response as follows: This patient appears to meet both obligate criteria (chronic urticaria and monoclonal IgM) as well as one minor criteria (leukocytosis and/or elevated CRP) of the Strasbourg diagnostic criteria of Schnitzler’s syndrome.(1) This would indicate a probable diagnosis. Schnitzler syndrome is a very rare immunological disease. Presenting signs and symptoms are an urticarial rash, intermittent fevers, myalgia, arthralgia, bone pain, lymphadenopathy, and peripheral neuropathy.

We confirm that the interleukin 1 inhibitor should be the first line of therapy in Schnitzler syndrome, and in the presented case we found it more effective than the interleukin 6 blockade. All patients fulfilled the Strasbourg diagnostic criteria for Schnitzler syndrome; they presented with urticarial rash, constitutional upset, fever accompanied by fatigue, arthralgia, myalgia, and bone pain. 2021-03-29 · Background: Schnitzler syndrome is characterized by an urticarial rash, a monoclonal gammopathy, and clinical, histological, and biological signs of neutrophil-mediated inflammation. The aim of this study was to assess the applicability and validity of the existing diagnostic criteria in real-life Schnitzler syndrome is a rare disabling autoinflammatory syndrome characterized by a chronic urticarial rash and monoclonal gammopathy, accompanied by intermittent fever, arthralgia or arthritis or bone pain. Diagnostic criteria have been established. The disease never remits spontaneously.

An incisional elliptical skin biopsy was taken to exclude urticarial vasculitis and immunoglobulins were checked as well as protein electrophoresis and early morning Bence-Jones protein. Between 1972 and 1974, Schnitzler reported on the association between chronic urticaria and an IgM monoclonal protein that ultimately led to the recognition of a distinct clinical syndrome that bears her name.1,2 Subsequently, the diagnostic criteria were put on a more secure footing by Lipsker et al.3 and then endorsed by the Schnitzler Syndrome Study Group.4 However, most of these studies The FIG. 3 Strasbourg diagnostic criteria of Schnitzler's syndrome adapted from Simon et al.

For the Strasbourg criteria, sensitivity for definite and probable diagnosis was 81% and 93%, respectively, with a corresponding specificity of 100% and 97%. Schnitzler syndrome, described in 1974, is an autoimmune chronic urticaria syndrome associated with a characteristic monoclonal IgM component, in addition to fever, joint pain and lymphadenopathy. 1 Several authors have reported patients with urticaria, fever, joint pain and increased erythrocyte sedimentation rate (ESR) and an IgG monoclonal component, suggesting that this could be a variant 2021-03-08 · The diagnostic criteria for this disorder include recurrent and nonprutic urticaria and monoclonal gammopathy (IgM Kappa light chain, > 90%) [ 3 ]. We identified 16 patients with diagnosed Schnitzler syndrome and an additional 46 patients who met diagnostic criteria. The monoclonal protein was IgMκ in 94% of patients.
