Functional Assessment of Disease-Associated Pyrin Variants.

Methods Mol Biol 2022 ;2523:179-195

CIRI (Centre International de Recherche en Infectiologie), Univ Lyon, Inserm U1111, Lyon, France.

The pyrin inflammasome detects effectors and toxins that inhibit RhoA GTPases and triggers inflammatory cytokines release and a fast cell death termed pyroptosis. Ancient plague pandemics in the Mediterranean basin have selected in the human population pyrin variants that can trigger an autoinflammatory disease termed familial Mediterranean fever (FMF). In addition, distinct mutations in MEFV, the gene encoding pyrin, cause a different rare autoinflammatory disease termed pyrin-associated autoinflammation with neutrophilic dermatosis (PAAND).

Clinical impact and disease evolution of SARS-CoV-2 infection in familial Mediterranean fever.

Pharmacol Res 2022 Jun 9;182:106293. Epub 2022 Jun 9.

Pediatric Clinic, Pietro Barilla Children's Hospital, University of Parma, Parma, Italy. Electronic address:

The innate immune system is critically involved in the pathogenesis of familial Mediterranean fever (FMF), characterized by dysregulated inflammasome activity and recurrent inflammatory attacks: this is the most common among monogenic autoinflammatory diseases, which shares some biochemical pathways with the severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) infection. In this short review we explore the overlap in the pathophysiology of FMF and SARS-CoV-2 infection, discussing how to understand better the interaction between the two diseases and optimize management. A poorer outcome of SARS-CoV-2 infection seems not to be present in infected FMF patients in terms of hospitalization time, need for oxygen support, need for intensive care, rate of complications and exitus.
