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. Table 1 Lipsker diagnostic criteria of Schnitzler syndrome (Medi-cine (Baltimore) 2001;80:37–44) Urticarial rash and monoclonal IgM component and at least two of the following criteria: Fever Arthralgia or arthritis Bone pain Palpable lymph nodes Liver or spleen enlargement Elevated ESR Leukocytosis Abnormal findings on bone morphologic investigations All patients with a Schnitzler syndrome met the Lipsker diagnostic criteria. According to the Schnitzler's is diagnosed if the person has IgM and two of the following, or IgG and three of the following: recurrent fevers, abnormalities in bone imaging, with or without bone pain, findings of neutrophil infiltration in a skin biopsy, high levels of white blood cells or C-reactive protein.

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. Therapy with anakinra in 4 patients led to rapid and complete resolution of symptoms.

2 This disorder often goes undiagnosed. 3 The rash is typically resistant to antihistamines, and histologically, it is a neutrophilic urticarial dermatosis. Background. Schnitzler syndrome is a rare disorder characterized by a chronic urticarial rash and monoclonal gammopathy (IgM in more than 90% of the cases). It is difficult to distinguish from other neutrophilic urticarial dermatoses, and diagnosis is based on the Strasbourg criteria.

Sensitivity and specificity of the Strasbourg criteria for definite diagnosis were 81% and 100% respectively (Gusdorf et al 2017).

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. Table 1 Lipsker diagnostic criteria of Schnitzler syndrome (Medi-cine (Baltimore) 2001;80:37–44) Urticarial rash and monoclonal IgM component and at least two of the following criteria: Fever Arthralgia or arthritis Bone pain Palpable lymph nodes Liver or spleen enlargement Elevated ESR Leukocytosis Abnormal findings on bone morphologic investigations All patients with a Schnitzler syndrome met the Lipsker diagnostic criteria.

More investigations must be done to attest their efficiency in patients with recent-onset manifestations. One control met the Lipsker criteria and had probable Schnitzler syndrome according to the Strasbourg criteria.

Table 2 Strasbourg diagnostic criteria of Schnitzler syndrome (Allergy 2013;68:562–568) Obligate criteria Chronic urticarial rash and Monoclonal IgM or IgG Minor Criteria Recurrent fever* Objective findings of abnormal bone remodeling with or without bone pain† A neutrophilic dermal infiltrate on skin biopsy‡ Leukocytosis and/or 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 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. The Schnitzler syndrome 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. Its main clinical features include fever, an urticarial rash, muscle, bone and/or joint pain and enlarged lymph nodes.

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.

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 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.
