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 patients.

Schnitzler syndrome occurs with a triad of chronic urticaria, recurring fevers, and monoclonal gammopathy.

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 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 A diagnosis of Schnitzler syndrome is often suspected based on the presence of characteristic signs and symptoms identified through physical exam, laboratory studies (i.e. 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).

Allergy. … One control met the Lipsker criteria and had probable Schnitzler syndrome according to the Strasbourg criteria. 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%. 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.

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.

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).
