Diagnosis demands exclusion of other inflammatory disorders such as hereditary episodic fever syndromes, adult-onset Still disease, urticarial vasculitis, mastocytosis, and systemic lupus erythematosus. Instead, Schnitzler syndrome is believed to arise from a problem with the immune system itself. It is uncertain what causes Schnitzler syndrome, but it does not appear to be hereditary. Patients with Schnitzler syndrome typically experience chronic rash, relapsing fevers, pain and inflammation in the joints, enlarged lymph nodes, and an excess of certain proteins in the blood. SchS diagnosis based on diagnostic criteria defined in Appendix; Patients with symptomatic Schnitzler syndrome [SchS] (as defined by the physician's global assessment with a minimum score of 8 and C-reactive protein [CRP] > upper limit of normal [ULN]) The Lipsker criteria require hives, the presence of monoclonal IgM, and at least 2 of the following: fever, joint pain or arthritis, bone pain, Nov 18, 2020 Inclusion criteria included a diagnosis of SchS (Strasbourg criteria).

Symptomatic ic urticaria to determine the true incidence of the disease. We compared patients with the diagnosis of Schnitzler syndrome and those who met the criteria but in We describe the clinical features and disease course of 11 patients with a definite Schnitzler syndrome, according to the Strasbourg diagnostic criteria, Schnitzler's syndrome (SS) is characterized by recurrent urticarial rash with the recently published diagnostic criteria for iMCD. She met both required major Diagnosis is based on established criteria. Ruling-out other diagnoses, like adult- onset Still's disease, Sweet syndrome and hypocomplementemic urticarial Schnitzler's syndrome was first reported in 1972 and Based on these findings, we favoured the diagnosis of the criteria that define Schnitzler's syndrome.

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.

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 … Conclusion: Diagnostic criteria currently in use to diagnose Schnitzler syndrome are reliable. More investigations must be done to attest their efficiency in patients with recent-onset manifestations.

A diagnosis of Schnitzler's syndrome is considered definite in any patient with two obligate criteria: a recurrent urticarial rash and a monoclonal IgM gammopathy, and two of the following minor criteria: recurrent fever, objective signs of abnormal bone remodeling, elevated CRP level or leukocytosis, and a neutrophilic infiltrate on skin biopsy.

Sensitivity and specificity of the Strasbourg criteria for definite diagnosis were 81% and 100% respectively (Gusdorf et al 2017). We focus on recent advances in diagnosis and therapeutic strategies, as well as on pathogenesis of Schnitzler syndrome.

2008-11-06 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 A 67-year-old man had a 6-year history of persistent, antihistamine-resistant urticaria.
