Interleukin-1 is considered the key mediator, and interleukin-1 inhibitors are considered first Summary Backgrounds: The most important diagnostic criteria for Schnitzler syndrome include chronic urticaria, the presence of monoclonal IgM immunoglobulin, marked inflammation (leukocytosis, elevated CRP and erythrocyte sedimentation rate), subfebrile temperatures or fevers and bone and joint pains. Sensitivity and specificity of the Lipsker criteria were 100% and 97%, respectively. For the Strasbourg criteria, sensitivity for definite and probable diagnosis was 81% and 93%, respectively, with a corresponding specificity of 100% and 97%. CONCLUSION: Diagnostic criteria currently in use to diagnose Schnitzler syndrome are reliable. The Schnitzler syndrome (SS) is a rare and acquired systemic disease, which bears in common many features with a group of inherited diseases, referred to as auto-inflammatory syndromes .

At 2 specialist UK centers, we have identified 21 patients who fulfilled diagnostic criteria for Schnitzler syndrome with urticarial rash, fever, arthralgia, and bone pain; 47% reported weight loss, 40% fatigue, and 21% lymphadenopathy. An immunoglobulin M (IgM) κ paraprotein was detected in 86%; the remainder had IgM λ or IgG κ. 2021-03-29 Schnitzler syndrome is a very rare immunological disease.

Schnitzler syndrome diagnostic criteria

2015-08-30 · The long-term outlook (prognosis) for people with Schnitzler syndrome is generally good. Although the condition is chronic and symptoms can be a nuisance, it generally does not progress to severe disease in most affected people. However, approximately 10-15% of people with Schnitzler syndrome develop a lymphoproliferative disorder. Diagnostic criteria of the Schnitzler syndrome HE, × 200): a neutrophilic infiltrate of the dermis without vasculitis and without significant edema. Treatments of patients with the Schnitzler In the early 1970s, the French dermatologist Liliane Schnitzler described a novel clinical syndrome characterized by chronic urticaria in association with a monoclonal IgM (less likely IgG) paraprotein, which ultimately was to bear her name. 1, 2 Subsequently, work by Lipsker 3 and de Koning et al 4 as well as the Schnitzler syndrome study group 5 led to a more standardized definition of the syndrome culminating in the development of the Strasbourg criteria for diagnosis (Table 1).

immunoelectrophoresis) and/or imaging studies. Additional testing should also be ordered to rule out other conditions that cause similar features. The Schnitzler syndrome is a rare and underdiagnosed entity which is considered today as being a paradigm of an acquired/late onset auto-inflammatory disease. It associates a chronic urticarial skin rash, corresponding from the clinico-pathological viewpoint to a neutrophilic urticarial dermatosis, a monoclonal IgM component and at least 2 of the following signs: fever, joint and/or bone pain The differential diagnosis at that time may include numerous inflammatory disorders such as juvenile rheumatoid arthritis, adult-onset Still's disease, inflammatory bowel disease, Schnitzler syndrome, and Behçet's disease, in addition to the hereditary periodic fever syndromes (Table 97-2). Because the hereditary syndromes are rare (except for Schnitzler syndrome is a chronic condition, and it has not been reported to resolve. Although symptoms can be a nuisance, the condition does not lead to serious disease in the majority of patients. However about 15% of patients progress to a lymphoproliferative disorder such as Waldenström macroglobulinemia or B-cell lymphoma .

De Koning slightly expanded the criteria by including the possibility of The diagnostic criteria of Schnitzler syndrome suggested in 2001 were revised by an expert meeting in Strasbourg and validated in a multicentric study (Lipsker et al 2001, Simon et al 2013, Gusdorf et al 2017). Sensitivity and specificity of the Strasbourg criteria for definite diagnosis were 81% and 100% respectively (Gusdorf et al 2017).
