2024 European Recommendations on Familial Mediterranean Fever (FMF) – Summary:

Familial Mediterranean Fever (FMF) is the most common monogenic autoinflammatory disease worldwide. Due to its clinical and genetic variability, specialized management is essential. In 2024, the EULAR and PReS societies updated their guidelines.

General Principles:

• FMF requires specialist expertise for both diagnosis and management.

• The primary goal is complete control of inflammation, including subclinical inflammation, to prevent complications such as AA amyloidosis.

• Lifelong treatment is necessary, with strict adherence, primarily based on daily colchicine therapy.

• Care should be patient-centered, aiming to preserve quality of life.

Key Recommendations:

• Colchicine should be initiated as soon as a clinical diagnosis is made.

• The dosage must be tailored to tolerance and adherence (single or divided daily doses).

• If symptoms persist or subclinical inflammation remains, the dose should be increased within recommended limits (maximum 2 mg/day in children, 3 mg/day in adults).

• If colchicine fails despite good adherence, interleukin-1 blockers (anakinra, canakinumab) are recommended.

• Chronic musculoskeletal manifestations may require additional treatments (DMARDs, biologics).

• Regular monitoring (clinical, biological, toxicity, adherence) is essential.

• Colchicine should be continued during pregnancy and breastfeeding.

• During acute attacks, colchicine should be maintained at the same dose, with symptomatic treatment added (e.g., NSAIDs).

• A minimum core set of assessment criteria is proposed: attack frequency, quality of life, biological markers (CRP, SAA).

Quality indicators, clinical priorities (especially adherence), and implementation strategies are provided to harmonize care across centers.

Liver disease complicating Familial Mediterranean Fever: a study on 66 patients out of 533 adult from the JIR cohort

Abstract:

Background: Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease, associated with MEFV mutations. FMF patients can experience liver involvement, potentially leading to cirrhosis.

Objectives: This study aimed to evaluate liver involvement in FMF patients at a French tertiary center for adult FMF.

Methods: We conducted an observational study with FMF patients displaying 2 pathogenic MEFV mutations at the Adult National Reference Centre for Autoinflammatory Diseases and Inflammatory Amyloidosis (CEREMAIA) in Paris and included in the JIR cohort. MEFV heterozygous patients and those with other liver disease causes were excluded.

Results: Among 533 FMF patients 12.4% had chronic liver abnormalities, with 30% who developed cirrhosis 54 years [36-57] in median after disease onset. Forty-seven percent were colchicine resistant, and 41% received interleukin-1 inhibitors. Cirrhotic patients experienced delayed hepatopathy diagnosis, prolonged FMF diagnosis delay, and late-onset treatment initiation compared to those with only liver function test abnormalities. Colchicine resistance and interleukin-1 inhibitor use were more common in cirrhotic patients. Body mass index and AA amyloidosis rates did not differ significantly between groups. Twenty-one patients undergone liver biopsies including 14 cirrhotic patients revealing steatohepatitis in 12 cases and probable steatohepatitis in 4. Other lesions, like iron overload and sinusoidal dilatation, were sporadically observed.

Conclusion: FMF patients are at risk of chronic liver disease. Regular liver function monitoring is crucial, particularly in case of persistent inflammation, due to the risk of progression to cirrhosis and its associated morbidity and mortality.

Lay Summary

More than, 10% of FMF patients develop chronic liver abnomalities over time and 4% cirrhosis. High-risk includes those with 2 MEFV mutations and colchicine resistance and chronic liver disease often begins after age 55 in FMF patients. In FMF patient with impaired liver function optimizing treatment targeting chronic inflammation is a key point in their care.

Clostridioides difficile infection as a potential trigger for Familial Mediterranean Fever attacks and fecal transplantation as a rescue

Familial Mediterranean Fever (FMF) is the most common monogenic autoinflammatory disease in the world. It is associated with mutations in the MEFV gene, which encodes pyrin.

The diagnosis of Clostridium difficile infection is complex in patients with FMF, as during FMF crises, the most frequent symptoms include febrile abdominal pain accompanied by a biological inflammatory syndrome, manifestations common to both conditions.

The B toxin of Clostridium difficile is a specific activator of the pyrin inflammasome.

Clostridium difficile infection complicating FMF is a rare but serious and potentially fatal infection.

It should be suspected in FMF patients presenting with unexplained persistent inflammation and/or chronic abdominal pain and/or unusual diarrhea.

=> The B toxin of C. difficile can then be tested in stool samples to exclude a false resistance to colchicine and avoid mistakenly starting anti-interleukin 1 biotherapy.

=> C. difficile infection in an FMF patient must be actively treated, including fecal transplantation if necessary.
