Aim:
Familial Mediterranean Fever (FMF) is the most common recurrent autoinflammatory fever syndrome. Still, many issues-e.g.: colchicine dosage adjustment, maximum dosage of colchicine in children and adults, definition of colchicine resistance, alternative treatment solutions in colchicine-resistant patients, and genetic screening for asymptomatic siblings-have not yet been standardized. The current paper aims at summarizing consensus recommendations to approach these issues.
Methods:
A literature review concerning these practical management questions was performed through PubMed. On the basis of this analysis, expert recommendations were developed during a consensus meeting of caregivers from France and Israel.
Results:
A patient experiencing more than four FMF attacks a year needs colchicine dose adjustment. In case of persistent attacks (≥6 per year) in patients with maximum doses of colchicine (2 mg in children; 3 mg in adults), alternative treatment to colchicine with IL1 inhibitors should be considered. Routine genetic testing for MEFV mutations in asymptomatic siblings of an index case is not recommended.
Conclusion:
This is a first attempt to resolve practical questions in the daily management of FMF patients.
Insights
Familial Mediterranean Fever (FMF) management requires colchicine dose adjustment for frequent attacks. For resistant cases, IL1 inhibitors are recommended, and routine genetic screening for asymptomatic siblings is not advised.
Area of Science:
- Rheumatology
- Genetics
- Immunology
Background:
- Familial Mediterranean Fever (FMF) is a prevalent autoinflammatory disorder characterized by recurrent fevers.
- Current FMF management faces standardization challenges regarding colchicine therapy and genetic screening.
- Key issues include colchicine dosage, resistance definition, alternative treatments, and genetic testing for asymptomatic relatives.
Purpose of the Study:
- To provide consensus recommendations for practical management of FMF patients.
- To address unresolved issues in daily FMF care, including colchicine use and genetic screening.
- To standardize approaches to colchicine dosage adjustment, resistance, and alternative therapies.
Main Methods:
- A comprehensive literature review of PubMed was conducted.
- Expert recommendations were formulated during a consensus meeting.
- The review focused on practical management questions in FMF.
Main Results:
- Colchicine dose adjustment is indicated for FMF patients with >4 attacks/year.
- IL1 inhibitors are recommended for FMF patients with persistent attacks (≥6/year) on maximum colchicine doses.
- Routine genetic testing for MEFV mutations in asymptomatic siblings is not recommended.
Conclusions:
- This consensus provides a framework for addressing practical FMF management challenges.
- The recommendations aim to improve daily care for FMF patients.
- This represents a significant step towards standardizing FMF treatment protocols.
