Objectives: To test the hypothesis that alterations in the Mediterranean fever (MEFV) gene are a susceptibility factor for the development of polyarteritis nodosa (PAN) we investigated the prevalence of MEFV mutations in patients with PAN without any symptoms of familial Mediterranean fever (FMF).
Study Design: Pediatric patients with PAN (n = 29) were enrolled in this study. Six predominant mutations (p.M694V, p.M680I, p.M694I, p.V726A, p.K695R, p.E148Q) in the MEFV gene were studied.
Results: Fifteen MEFV mutations were identified in 58 chromosomes. Eleven of the 29 patients (38%) were found to carry MEFV mutations. Three (10.3%) of them had homozygous p.M694V mutation, and one of the patients (3.4%) had compound heterozygous mutation (p.V726A/p.E148Q).
Conclusions: Our study confirms that alterations in the MEFV gene are important susceptibility factors for the development of PAN. We believe that mutations in MEFV gene provide a basis for the development of PAN both by forming a proinflammatory state and by possibly giving exaggerated response to streptococcal infections.

Schnitzler syndrome is a unique autoinflammatory disease, of which 747 cases have been described worldwide to date. The main features of the syndrome are a triad of recurrent urticaria, monoclonal IgM gammopathy, systemic inflammation associated with recurrent fever, joint and bone pain, and atypical bone remodeling (osteosclerosis). The abnormal activation of the NLRP3 inflammasome produces IL-1, which drives the disease pathology, but it also involves IL-6 and IL-18.

Background: Irritable bowel syndrome (IBS) is a common gastrointestinal disorder seen by both primary care providers (PCPs) and gastroenterologists, and further diagnostic testing is generally discouraged unless red-flag symptoms are present.
Aims: Examine if advanced serologic testing for chronic abdominal pain in IBS patients followed society-specific guidelines and evaluate the diagnostic accuracy of these tests.
Methods: The study involved a retrospective cross-sectional analysis of adults aged 18 and older who were seen at our institution between 2013 and 2018.

PANoptosis is one of several modes of programmed cell death (PCD) and plays an important role in many inflammatory and immune diseases. The role of PANoptosis in inflammatory bowel disease (IBD) is currently unknown. Differentially expressed PANoptosis-related genes (DE-PRGs) were identified, and pathway enrichment analyses were performed.

Purpose: Familial Mediterranean fever (FMF) is an autosomal recessive disorder characterized by recurrent episodes of fever and serositis, caused by mutations in the gene. Inflammatory pathways associated with FMF are linked to increased proinflammatory cytokines, which may be related to primary headaches, including migraine. The aim of this study was to evaluate the frequency of migraine and other primary headaches in FMF patients.

Background: Familial Mediterranean Fever is a common genetic autoinflammatory disease prevalent in the Mediterranean region. The clinical course of the disease is characterized by fever and serositis attacks. While defects in the innate immune system are known to play a role in the pathogenesis of the disease, the impact of the adaptive immune system remains unclear.
