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.

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. Monoclonal IgM gammopathy is the main pathological feature that leads to symptoms while a chronic relapsing course is usually observed. The diagnosis rests on clinical criteria, a 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. Schnitzlers syndrom är en ovanlig sjukdom som karakteriseras av kronisk urtikaria, monoklonal gammopati, oftast av IgM-typ, intermittent feber, artrit och artralgi, bensmärta, förhöjda inflammatoriska parametrar (SR, CRP), leukocytos samt ibland hepato- eller splenomegali och lymfadenopati.

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).

Occurs usually-but not obligatorily-together with the 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) . 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. The cytokine interleukin-1 (IL-1) plays a crucial role in the pathogenesis of the Schnitzler syndrome, and this explains the 2019-10-24 · All patients with a diagnosis of Schnitzler syndrome (according to Strasbourg's and Lipsker's criteria) who had at least one PET/CT were included. Data were collected from medical records. PET/CT scans were all reviewed by a nuclear physician blinded to the clinical and imaging data. Objective To report on the characteristics and long-term course of rheumatic manifestations in Schnitzler syndrome (SchS).

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).

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.

PET/CT scans were all reviewed by a nuclear physician blinded to the clinical and imaging data. review 4 biopsies of patients with the Schnitzler Table 1 Diagnostic criteria of the Schnitzler syndrome Urticarial skin rash1,2 and monoclonal IgM component3 and at least 2 of the following criteria4: Fever Arthralgia or arthritis Bone pain Palpable lymph nodes Liver or spleen enlargement Elevated ESR Leukocytosis Schnitzler syndrome is a rare disorder characterized by recurrent or chronic urticaria associated with a monoclonal gammopathy and persistent inflammation. 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.

Schnitzler's syndrome is characterized by recurrent urticarial rash and monoclonal gammopathy, associated with clinical and biological signs of inflammation and a long-term risk of AA amyloidosis and overt lymphoproliferation.

Definitive diagnosis requires two major criteria and at least two minor criteria. Probable diagnosis is the presence of two major criteria and at least one minor criteria if IgM or two minor criteria if IgG. Major criteria are as follows: Schnitzler’s syndrome is characterized by recurrent urticarial rash and monoclo-nal gammopathy, Diagnostic criteria. Since the 2001 publication of diagnostic criteria by Lipsker et al., authors have referred to those crite-ria in almost all subsequently published cases (4). 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).

The probable pathogenesis is interleukin-1 (IL-1) mediated and is an acquired disease involving the abnormal stimulation of the innate immune system. The lymphoproliferative disorder develops in about 15% to 20% of patients with a Schnitzler’s syndrome sharing .
