Update in familial Mediterranean fever

Area of Science:

• Autoinflammatory diseases
• Genetics
• Immunology

Background:

• Familial Mediterranean fever (FMF) is a prototypic autoinflammatory disease.
• Despite the MEFV gene identification 24 years ago, FMF pathogenesis and phenotype variations require further understanding.
• Recent advancements offer insights into FMF genetics, classification, and treatment.

Purpose of the Study:

• To review recent findings in Familial Mediterranean Fever (FMF).
• To discuss updated understanding of FMF genetics and phenotype.
• To highlight new classification criteria and treatment approaches.

Main Methods:

• Review of recent scientific literature on FMF.
• Analysis of genetic studies, including epigenetic factors.
• Evaluation of long-term data on anti-IL1 treatment efficacy.

Main Results:

• MEFV gene mutations confer resistance to plague, explaining historical selection.
• New expert recommendations for MEFV genetic analysis and FMF classification criteria have been established.
• Long-term data supports anti-IL1 treatment for colchicine-resistant FMF patients.

Conclusions:

• Updated recommendations for MEFV genetic analysis and FMF classification are available.
• Further research is necessary to elucidate genetic and environmental factors influencing FMF inflammation and phenotype.
• Understanding FMF presentation and progression remains an active area of investigation.
