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).

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).

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. The median overall survival for this syndrome is over 12.8 years.

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.

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. 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 2019-03-12 · Schnitzler syndrome is characterized by chronic, nonpruritic urticaria in association with recurrent fever, bone pain, arthralgia or arthritis, and a monoclonal immunoglobulin M (IgM) gammopathy in a concentration of usually less than 10 g/L.
