Febris mediterranea familiaris
Leczenie
Febris mediterranea familiaris (FMF) to dziedziczna choroba autozapalna charakteryzująca się nawracającymi atakami gorączki i zapalenia błon surowiczych. Podstawą leczenia jest kolchicyna, stosowana w dawkach indywidualizowanych: u dorosłych 1-2 mg/dobę, z możliwością zwiększenia do 3 mg/dobę, u dzieci 0,3-1,2 mg/dobę, maksymalnie do 2 mg/dobę. Kolchicyna zapobiega atakom u ponad 90% pacjentów, zmniejsza ich nasilenie oraz chroni przed amyloidozą AA – najgroźniejszym powikłaniem FMF. Leczenie jest przewlekłe, a przerwanie terapii prowadzi do nawrotów i zwiększa ryzyko amyloidozy. Monitorowanie skuteczności i toksyczności powinno odbywać się co 6 miesięcy, w tym badania krwi i moczu co najmniej dwa razy w roku. Oporność na kolchicynę dotyczy 5-10% pacjentów i wymaga potwierdzenia maksymalną tolerowaną dawką przez minimum 6 miesięcy.

Leczenie Febris mediterranea familiaris (FMF)
Febris mediterranea familiaris (FMF) to dziedziczna choroba autozapalna, która charakteryzuje się nawracającymi atakami gorączki i zapalenia błon surowiczych. Mimo że obecnie nie istnieje metoda leczenia przyczynowego, dostępne są skuteczne opcje terapeutyczne, które pozwalają kontrolować objawy i zapobiegać powikłaniom. Głównym celem leczenia jest uzyskanie pełnej kontroli nad nieprowokowanymi atakami oraz minimalizacja subklinicznego zapalenia między atakami, co ma zapobiegać rozwojowi powikłań, takich jak amyloidoza AA12.
Kolchicyna – podstawa leczenia FMF
Kolchicyna jest podstawowym lekiem w terapii FMF od lat 70. XX wieku. Jest to alkaloid hamujący proces zapalny poprzez blokowanie chemotaksji neutrofilów, które odgrywają kluczową rolę w inicjowaniu ataków FMF34. Leczenie kolchicyną powinno być rozpoczęte natychmiast po ustaleniu rozpoznania klinicznego5.
Regularne przyjmowanie kolchicyny w dawce dostosowanej do potrzeb pacjenta pozwala na6:
- Zapobieganie lub zmniejszenie częstotliwości ataków u ponad 90% pacjentów
- Zmniejszenie nasilenia ataków, które mimo leczenia wystąpią
- Zapobieganie rozwojowi wtórnej amyloidozy, najgroźniejszego powikłania FMF
Dawkowanie kolchicyny jest zindywidualizowane i zależy od wieku pacjenta, masy ciała oraz nasilenia objawów. U dorosłych standardowa dawka wynosi 1-2 mg/dobę, podczas gdy u dzieci dawka jest dostosowywana według wieku i masy ciała, rozpoczynając od 0,3-1,2 mg/dobę78. W przypadku utrzymywania się ataków lub obecności przewlekłego stanu zapalnego, dawka może być stopniowo zwiększana do maksymalnie 3 mg/dobę u dorosłych i 2 mg/dobę u dzieci9.
Kolchicynę można podawać w dawce pojedynczej lub podzielonej, w zależności od tolerancji i przestrzegania zaleceń przez pacjenta10. Badania wykazały, że u nowo zdiagnozowanych, nieleczonych wcześniej pacjentów pediatrycznych pojedyncza dawka dobowa 1 mg była nie mniej skuteczna niż dawka 0,5 mg podawana dwa razy dziennie7.
Skuteczność i czas trwania leczenia kolchicyną
Kolchicyna zapewnia całkowitą remisję lub wyraźną poprawę u około 95% pacjentów11. Jest szczególnie skuteczna w przypadku gorączki, zapalenia otrzewnej i opłucnej. Zapobiega ona rozwojowi amyloidozy nawet w przypadkach, gdy nie udaje się całkowicie wyeliminować ataków12.
Leczenie kolchicyną powinno być prowadzone przez całe życie, ponieważ zaprzestanie terapii zwykle prowadzi do nawrotu ataków w ciągu kilku dni13. Ponadto, przerwanie leczenia wiąże się ze zwiększonym ryzykiem rozwoju amyloidozy14.
Monitoring odpowiedzi na leczenie, toksyczności i przestrzegania zaleceń powinien być przeprowadzany co 6 miesięcy15. Pacjenci powinni mieć wykonywane badania krwi i moczu co najmniej dwa razy w roku w celu oceny skuteczności leczenia i wykrycia ewentualnych działań niepożądanych16.
Przyczyny niepowodzenia leczenia kolchicyną
Około 5-10% pacjentów z FMF nie odpowiada na leczenie kolchicyną17. Najczęstszą przyczyną niepowodzenia terapii jest nieprzestrzeganie zaleceń przez pacjenta, często spowodowane działaniami niepożądanymi ze strony przewodu pokarmowego, takimi jak biegunka czy nudności1811.
Oporność na kolchicynę może być również związana z polimorfizmami genu ABCB1, które wpływają na wchłanianie kolchicyny przez komórki jednojądrzaste18.
Przed zdiagnozowaniem oporności na kolchicynę należy upewnić się, że pacjent przyjmuje maksymalną tolerowaną dawkę leku przez co najmniej 6 miesięcy i nadal doświadcza co najmniej jednego ataku miesięcznie515.
Leki biologiczne w leczeniu FMF
W przypadku pacjentów, którzy nie odpowiadają na leczenie kolchicyną lub nie tolerują tego leku, alternatywą są leki biologiczne, szczególnie inhibitory interleukiny-1 (IL-1). Leki te są zalecane jako druga linia leczenia u pacjentów z FMF oporną na kolchicynę lub nietolerujących kolchicyny1920.
Dostępne inhibitory IL-1 stosowane w leczeniu FMF to2122:
- Kanakinumab (Ilaris) – przeciwciało monoklonalne przeciwko IL-1β, zatwierdzone przez FDA do leczenia FMF w 2016 roku
- Anakinra (Kineret) – antagonista receptora IL-1
- Rilonacept (Arcalyst) – białko fuzyjne wiążące IL-1
Przegląd systematyczny wykazał, że u pacjentów, którzy nie odpowiadają na kolchicynę lub nie tolerują jej, leczenie anty-IL-1 skutkowało całkowitą odpowiedzią na terapię, bez ani jednego ataku w trakcie leczenia, u 76,5% pacjentów leczonych anakinrą i 67,5% leczonych kanakinumabem23.
Metaanaliza wykazała, że leki anty-IL-1 zapewniają znaczącą poprawę parametrów laboratoryjnych u pacjentów z FMF poprzez zmniejszenie OB i poziomu CRP. U dorosłych pacjentów poziom CRP obniżył się po leczeniu inhibitorami IL-1 o 36,56 mg/L, a OB o 30,36 mm/h2425.
Pomimo przejścia na leczenie biologiczne, zaleca się kontynuowanie przyjmowania kolchicyny w maksymalnej tolerowanej dawce, ponieważ może to zmniejszyć ryzyko amyloidozy, nawet jeśli ataki utrzymują się15.
Leczenie amyloidozy w przebiegu FMF
Amyloidoza AA jest najpoważniejszym powikłaniem nieleczonej FMF, które może prowadzić do niewydolności nerek i przedwczesnego zgonu5. Leczenie amyloidozy obejmuje526:
- Intensyfikację leczenia FMF z zastosowaniem maksymalnej tolerowanej dawki kolchicyny
- W razie potrzeby dodanie leków biologicznych, szczególnie inhibitorów IL-1
- Środki wspomagające niewydolną funkcję narządów, w tym kontrolę ciśnienia krwi
- Hemodializę w przypadku pacjentów z niewydolnością nerek
Kolchicyna stabilizuje poziom białkomoczu u pacjentów z nefropatią amyloidową26. W przypadku pacjentów z rozwiniętą amyloidozą typu AA, leczenie inhibitorami IL-1 może nawet odwrócić białkomocz27.
Alternatywne opcje terapeutyczne
Oprócz kolchicyny i inhibitorów IL-1, w leczeniu FMF stosowane są również inne leki1923:
- Inhibitory TNF-alfa (etanercept, infliksymab, adalimumab) – opisywane w niektórych przypadkach, choć ich rzeczywista skuteczność nie została jeszcze w pełni ustalona
- Dapson – może być korzystny w połączeniu z kolchicyną u pacjentów, którzy mają niewystarczającą odpowiedź na kolchicynę, ale nie mogą sobie pozwolić na leki biologiczne
- Talidomid – stosowany w wybranych przypadkach
- Tocilizumab – inhibitor receptora IL-6, badany w leczeniu FMF z mieszanymi wynikami, z korzyściami obserwowanymi szczególnie u pacjentów z rozwiniętą amyloidozą AA
- Interferon alfa – opisywany w niektórych przypadkach
W przypadku pacjentów z FMF, którzy rozwinęli przewlekłe zapalenie stawów lub zapalenie stawów krzyżowo-biodrowych, mogą być stosowane niesteroidowe leki przeciwzapalne (NLPZ) jako leczenie pierwszego rzutu, leki modyfikujące przebieg choroby (DMARDs), dostawowe iniekcje steroidów lub leki biologiczne28.
Leczenie objawowe podczas ataków
Leczenie ostrego ataku FMF ma na celu złagodzenie objawów i obejmuje2917:
- Niesteroidowe leki przeciwzapalne (NLPZ) do leczenia gorączki, bólu i stanu zapalnego
- Leki przeciwbólowe, takie jak paracetamol
- Dożylne płyny w celu nawodnienia
- W przypadku epizodów przedłużonego bólu mięśni z gorączką i silnym bólem, pacjenci mogą wymagać leczenia prednizonem (1 mg/kg) przez okres do 6 tygodni
Ważne jest, aby podczas ataku kontynuować standardową dawkę kolchicyny9.
Monitorowanie leczenia
Regularne monitorowanie pacjentów z FMF jest niezbędne do oceny skuteczności leczenia i wczesnego wykrycia powikłań21. Zaleca się515:
- Ścisłe monitorowanie pacjentów przez 36 miesięcy po rozpoczęciu leczenia kolchicyną w celu oceny efektu terapeutycznego
- Regularne badania krwi i moczu co najmniej dwa razy w roku
- Regularne oznaczanie poziomu enzymów wątrobowych u pacjentów leczonych kolchicyną
- Badanie moczu na obecność białka co 6 miesięcy, nawet u pacjentów z łagodnymi objawami
W przypadku pacjentów z obniżoną funkcją nerek, ryzyko toksyczności kolchicyny jest bardzo wysokie, dlatego należy rutynowo poszukiwać oznak toksyczności i w razie ich stwierdzenia odpowiednio zmniejszyć dawkę kolchicyny9.
Uwagi szczególne
Ciąża i laktacja
Kolchicyna nie powinna być odstawiana podczas planowania ciąży, w trakcie ciąży ani w okresie karmienia piersią289. Aktualne dowody nie uzasadniają wykonywania amniocentezy. U kobiet ciężarnych kolchicyna pomaga zapobiegać atakom, które mogłyby prowadzić do poronienia30.
Płodność męska
Mężczyźni generalnie nie muszą przerywać leczenia kolchicyną przed poczęciem. W rzadkich przypadkach azoospermii lub oligospermii udowodnionej jako związana z kolchicyną, może być wymagane tymczasowe zmniejszenie dawki lub przerwanie leczenia2831.
Przypadki specjalne
Okresy fizycznego lub emocjonalnego stresu mogą wyzwalać ataki FMF i warto wtedy tymczasowo zwiększyć dawkę kolchicyny28. W przypadku pacjenta stabilnego, bez ataków przez ponad 5 lat i bez podwyższonych wskaźników ostrej fazy, można rozważyć zmniejszenie dawki po konsultacji z ekspertem i przy dalszym monitorowaniu28.
Badanie tureckie wykazało, że u dzieci heterozygotycznych pod względem wariantów MEFV, które wymagały rozpoczęcia leczenia kolchicyną po wystąpieniu objawów FMF, kolchicyna może być w niektórych przypadkach skutecznie odstawiona, jeśli zapewniona jest bardzo staranna obserwacja26.
Aktualne podejście do leczenia FMF
Europejska Liga do Walki z Reumatyzmem (EULAR) opublikowała zalecenia dotyczące leczenia FMF, które podkreślają, że celem terapii jest uzyskanie co najmniej minimalnej aktywności choroby i kontrola subklinicznego zapalenia, aby zapobiec uszkodzeniom narządów32.
Kolchicyna pozostaje podstawą leczenia FMF, skutecznie zapobiegając atakom zapalnym i powikłaniom. Dla pacjentów opornych na kolchicynę lub jej nietolerujących, inhibitory IL-1, takie jak anakinra i kanakinumab, stanowią obiecującą drugą linię leczenia20.
Nowsze podejście do leczenia FMF obejmuje strategię „treat-to-target” (T2T), która wprowadza eskalację i de-eskalację leczenia w zależności od osiągnięcia liczbowych celów terapeutycznych. Proponowany konsensusowy plan leczenia FMF uwzględnia wielowymiarowe cele, umożliwiając transparentne decyzje terapeutyczne, które będą promować spersonalizowane zarządzanie chorobą i zwiększać adherencję do terapii33.
Mimo że FMF jest chorobą przewlekłą wymagającą dożywotniego leczenia, właściwe postępowanie terapeutyczne umożliwia pacjentom prowadzenie normalnego, pełnowartościowego życia z dobrą jakością i normalną długością życia1634.

- #1 EULAR recommendations for the management of familial Mediterranean fever | Annals of the Rheumatic Diseaseshttps://ard.bmj.com/content/75/4/644
Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease, but many rheumatologists are not well acquainted with its management. The objective of this report is to produce evidence-based recommendations to guide rheumatologists and other health professionals in the treatment and follow-up of patients with FMF. […] A set of widely accepted recommendations for the treatment and monitoring of FMF is presented, supported by the best available evidence and expert opinion. It is believed that these recommendations will be useful in guiding physicians in the care of patients with FMF. […] The ultimate goal of treatment in FMF is to obtain complete control of unprovoked attacks and minimise subclinical inflammation in between attacks. […] Biological treatment such as anti-interleukin 1 (IL-1) therapy should be considered if the inflammation cannot be controlled with adequate colchicine.
- #2 Management of familial Mediterranean fever – UpToDatehttps://www.uptodate.com/contents/management-of-familial-mediterranean-fever
Management of familial Mediterranean fever […] GOALS OF THERAPY […] The goals of therapy for familial Mediterranean fever (FMF) are to prevent acute attacks and minimize subclinical inflammation in between attacks. Controlling inflammation even during asymptomatic intervals can prevent the development and progression of secondary (AA) amyloidosis. […] […] […] This topic will review the management of FMF.

Familial Mediterranean fever (FMF) is an autoinflammatory genetic disorder that mainly affects people of Mediterranean origin. […] Early initiation with colchicine leads to improvement in the attacks and prevent amyloidosis. […] Describe the role of colchicine and other agents in the management of familial Mediterranean fever. […] Colchicine has been the treatment of choice for FMF since the 1970s. The aim of the treatment is to prevent attacks, normalize inflammation between the attacks, and prevent the development of amyloidosis. It can also halt the progression of amyloidosis. […] Colchicine works by inhibiting neutrophil chemotaxis, which is necessary for the inflammatory events in FMF. […] The treatment with colchicine is usually lifelong. Dosing varies according to age and severity of symptoms.
- #4 Pharmacological and Clinical Basis of Treatment of Familial Mediterranean Fever (FMF) with Colchicine or Analogues: An Updatehttps://benthamscience.com/public/article/35772
Familial Mediterranean Fever (FMF), an autosomal recessive disorder, is characterised by recurrent attacks of fever and serositis, lasting 24-72 hours. Since 1972 colchicine has become the drug of choice for prophylaxis against FMF attacks and amyloidosis FMF-associated. Colchicine is able to prevent activation of neutrophils, binding -tubulin and making -tubulin-colchicine complexes; this way inhibits assembly of microtubules and mitotic spindle formation; moreover its mode of action includes modulation of chemokines, prostanoids production, inhibition of neutrophil and endothelial cell adhesion molecules. The minimal daily dose in adults is 1.0 mg / die, but in children there is not a definite dose. […] FMF patients are recommended to take colchicine. Since colchicine treatment is often complicated by frequent gastrointestinal side effects, by our experience, in order to improve colchicine tolerance we recommend: lactose-free diet and treatment of intestinal bacterial overgrowth and / or Hp-infection, assessed by breath tests. […] today we are working in the design of colchicine analogues which may have lesser toxicities and a larger therapeutic window.
- #5 EULAR recommendations for the management of familial Mediterranean fever | Annals of the Rheumatic Diseaseshttps://ard.bmj.com/content/75/4/644
Treatment with colchicine should be started as soon as a clinical diagnosis is made. […] A genetic diagnosis of FMF in the absence of clinical manifestations or subclinical inflammation is not necessarily an indication to start treatment, but such patients must remain under surveillance since they may develop clinically significant disease in future, even without symptoms. […] The persistence of attacks or subclinical inflammation represents an indication to increase colchicine dose. […] Patients who continue to have one or more attacks each month despite receiving the maximally tolerated dose for at least 6 months may be considered to be a non-responder or resistant to colchicine, although compliance to treatment must be affirmed. […] AA amyloidosis is the most serious complication of uncontrolled FMF, resulting in renal failure and early death. […] Treatment for amyloidosis comprises measures to support failing organ function, including blood pressure control and dialysis for patients with renal disease.
- #6 Familial Mediterranean Fever (FMF): What It Is & Symptomshttps://my.clevelandclinic.org/health/diseases/familial-mediterranean-fever
Taking an oral medication called colchicine can effectively prevent or reduce these episodes. Most people with FMF have to take it daily for life. […] The standard treatment for familial Mediterranean fever is an anti-inflammatory medication called colchicine. It works by inhibiting the activity of white blood cells called neutrophils, which play a role in inflammation. Colchicine can help prevent or reduce the frequency of FMF attacks and its complications. It works for more than 90% of people with FMF. Most of these people will need to take it daily for life. […] A small number of people don’t respond to colchicine or can’t take it for health-related reasons. Alternative medications include: Anakinra, Rilonacept, Canakinumab.
- #7 Familial Mediterranean Fever Treatment & Management: Medical Care, Surgical Care, Consultationshttps://emedicine.medscape.com/article/330284-treatment
Colchicine is so effective in preventing attacks of familial Mediterranean fever (FMF) and preventing the development of amyloidosis that the most important aspects of medical care are to make the correct diagnosis and to institute therapy. […] Administer colchicine therapy daily in patients at risk of developing amyloidosis (eg, North African Jewish people, Turkish people, Armenian people living in Armenia). Other Sephardic Jewish people and Arabic people are at lower risk but also probably require daily colchicine therapy. […] Daily colchicine is customarily given in a dosage of 0.6 or 0.5 mg twice daily, depending on the dosage form available. However, a study in treatment-naive pediatric patients newly diagnosed with FMF found that a single 1-g daily dose was noninferior to 0.5 mg given twice daily.
- #8 Diagnosis and management of familial Mediterranean fever: Integrating medical genetics in a dedicated interdisciplinary clinic | Genetics in Medicinehttps://www.nature.com/articles/gim9201147
Colchicine should be administered orally once the diagnosis of FMF is confirmed (or as a therapeutic trial in establishing the diagnosis). Adult dosing is 1.22.4 mg/day, whereas children usually start at 0.31.2 mg/day according to age and weight and can increase sequentially up to 2 mg/day depending on how effectively the attacks are regulated. […] It is crucial to drive home to patients (or their parents) that daily lifelong administration of colchicine is required to prevent both the fever/pain attacks and the silent amyloid deposition. […] If proteinuria is detected in a patient with FMF, more definitive renal studies are necessary, including a 24-hour urine protein assay and renal function tests (blood urea nitrogen and creatinine), and referral to a nephrologist for further work-up and management.
- #9 Familial Mediterranean Fever Guidelines: Guidelines Summaryhttps://emedicine.medscape.com/article/330284-guidelines
In patients with decreased renal function, the risk of colchicine toxicity is very high, so evidence of toxicity should routinely be sought and if found, the colchicine dose should be reduced accordingly. […] Colchicine toxicity is a serious complication that should be given adequate consideration and be prevented; potential causes include exceeding the recommended dose (maximum recommended oral doses for treatment of FMF are 3 mg daily in adults and 2 mg daily in children), liver or renal failure, and concomitant administration of other drugs metabolized by cytochrome 3A4. […] If an attack is suspected, always consider other possible causes; during attacks, continue the usual dose of colchicine and use nonsteroidal anti-inflammatory drugs (NSAIDs). […] Colchicine should not be discontinued during conception, pregnancy, or lactation; current evidence does not justify amniocentesis.
- #10 Familial Mediterranean Fever Guidelines: Guidelines Summaryhttps://emedicine.medscape.com/article/330284-guidelines
Ideally, FMF should be diagnosed and initially treated by a physician with experience in FMF; after diagnosis and initiation of therapy, patients can also be followed by their primary care physician in conjunction with the referral center, but if possible, patients should be seen by a physician with experience of FMF at least once per year in the long term. […] The ultimate goal of treatment in FMF is to obtain complete control of unprovoked attacks and minimize subclinical inflammation between attacks. […] Treatment with colchicine should be started as soon as a clinical diagnosis is made. […] Colchicine can be given in single or divided doses, depending on tolerance and compliance. […] Persistent attacks or subclinical inflammation represent an indication to increase the colchicine dose.
- #11 Familial Mediterranean Fever – Pediatrics – Merck Manual Professional Editionhttps://www.merckmanuals.com/professional/pediatrics/hereditary-periodic-fever-syndromes/familial-mediterranean-fever
Daily prophylactic colchicine should be initiated as soon as the diagnosis is made to prevent attacks as well as amyloidosis. Colchicine provides complete remission or distinct improvement in almost 95% of patients. If attacks or subclinical inflammation persist, the colchicine dose should be increased. Patients who are colchicine-resistant or -intolerant may be treated with IL-1 inhibitors (anakinra once a day, rilonacept weekly, or canakinumab every 4 weeks). However, the role of IL-1 inhibitors in preventing amyloidosis remains unknown, and patients taking IL-inhibitors should continue taking colchicine if tolerated. […] Widespread use of prophylactic colchicine has led to a dramatic reduction in the incidence of amyloidosis and subsequent renal failure. […] Lack of response to colchicine is often caused by poor adherence to the regimen.
- #12 Therapeutic approach to familial Mediterranean fever: a review update – PubMedhttps://pubmed.ncbi.nlm.nih.gov/21968242/
Familial Mediterranean fever (FMF) is a hereditary disorder characterised by recurrent attacks of fever with peritonitis or pleuritis, arthritis, myalgia or erysipelas-like skin lesions. […] Therefore, treatment of patients with FMF is beneficial not only for the prevention of the acute attacks but also for improving their prognosis. […] In conclusion, colchicine remains the mainstay therapeutic option in FMF. It is effective in various manifestations of the disease such as fever, peritonitis and pleuritis. It prevents the development of amyloidosis. It is safe in humans regarding fertility, and can be used during pregnancy and nursing. […] In the few cases where FMF is resistant to colchicine other measures, including corticosteroids, non-biological and biological DMARDs, interferon alpha and SSRIs should be employed.
- #13 About Familial Mediterranean Feverhttps://www.genome.gov/Genetic-Disorders/Familial-Mediterranean-Fever
At present, there is no known cure for Familial Mediterranean Fever (FMF). Physicians can only treat the symptoms of the disease. […] A common therapy for FMF is daily use of the drug colchicine, a medicine that reduces inflammation. This therapy has been successful in preventing attacks of fever in 75 percent of patients who take the drug regularly, and over 90 percent of patients demonstrate a marked improvement. Even if colchicine does not prevent the fever attacks, it does prevent the amyloidosis. However, compliance in taking colchicine every day is very important. If a patient stops taking the drug, an attack can occur within a couple of days. […] Since the gene that causes FMF codes for the protein pyrin, researchers hope that by studying how this protein works they will ultimately develop improved treatments for FMF, and possibly for other conditions involving excess inflammation.
- #14 Familial Mediterranean Feverhttps://www.printo.it/pediatric-rheumatology/IE/info/20/Familial-Mediterranean-Fever
Familial Mediterranean Fever (FMF) is a genetically transmitted disease. Patients suffer from recurrent bouts of fever, accompanied by abdominal or chest pain, joint pains and swelling. […] FMF cannot be cured but it can be treated with life-long use of colchicine. In this way, recurrent attacks can be prevented or decreased and amyloidosis can be prevented. If the patient stops taking the drug, the attacks and the risk of amyloidosis will recur. […] The treatment for FMF is simple, inexpensive and does not involve any major drug side effects, as long as it is taken in the right dose. Colchicine is the drug of choice for the treatment of FMF. After the diagnosis is made, the child must take the drug for the rest of his/her life. If taken properly (every day, at sufficient dose) the attacks: disappear in about 60% of patients; a partial response is obtained in 30%; and it is ineffective in 5-10% of patients. This treatment not only controls the attacks but also eliminates the risk of amyloidosis.
- #15 Familial Mediterranean Fever Guidelines: Guidelines Summaryhttps://emedicine.medscape.com/article/330284-guidelines
Compliant patients who continue to have one or more attacks each month despite receiving the maximally tolerated dose of colchicine for at least 6 months can be considered nonresponders or resistant; alternative biological treatments are indicated in these patients; colchicine should be coadministered with biological therapies, as it may reduce the risk of amyloidosis despite persistence of attacks. […] FMF treatment needs to be intensified in AA amyloidosis, using the maximal tolerated dose of colchicine and supplemented with biologics as required. […] Periods of physical or emotional stress can trigger FMF attacks, and it may be worth temporarily increasing the dose of colchicine. […] Response, toxicity, and compliance should be monitored every 6 months. […] Liver enzymes should be monitored regularly in patients with FMF treated with colchicine; if elevations greater than twofold the upper limit of normal occur, the colchicine dose should be reduced and the cause further investigated.
- #16 Familial Mediterranean Feverhttps://www.printo.it/pediatric-rheumatology/IE/info/20/Familial-Mediterranean-Fever
It is not easy to accept that a child must take pills forever. Parents are often worried about the potential side effects of colchicine. It is a safe drug with minor side effects that usually respond to dose reduction. The most frequent side effect is diarrhoea. […] FMF requires life-long preventive treatment. […] No complementary therapy is known for FMF. […] Children being treated should have blood and urine tests at least twice a year. […] If treated properly with life-long colchicine, children with FMF live a normal life. If there is a delay in diagnosis or lack of compliance with treatment, the risk of developing amyloidosis increases, which results in a poor prognosis. […] No, because it is a genetic disease. However, life-long therapy with colchicine gives the patient the opportunity to live a normal life, without restrictions and with no risk of developing amyloidosis.
- #17 Familial Mediterranean fever – Wikipediahttps://en.wikipedia.org/wiki/Familial_Mediterranean_fever
Attacks are self-limiting, and require analgesia and NSAIDs (such as diclofenac). Colchicine, a drug otherwise mainly used in gout, decreases attack frequency in FMF patients. The exact way in which colchicine suppresses attacks is unclear. While this agent is not without side effects (such as abdominal pain and muscle pains), it may markedly improve the quality of life in patients. The dosage is typically 12 mg a day. Development of amyloidosis is delayed with colchicine treatment. Interferon is being studied as a therapeutic modality. […] Approximately 5-10% of FMF cases are resistant to colchicine therapy alone. In these cases, adding anakinra to the daily colchicine regimen has been successful. Canakinumab, an anti-interleukin-1-beta monoclonal antibody, has likewise been shown to be effective in controlling and preventing flare-ups in patients with colchicine-resistant FMF and in two additional autoinflammatory recurrent fever syndromes: mevalonate kinase deficiency (hyper-immunoglobulin D syndrome, or HIDS) and tumor necrosis factor receptor-associated periodic syndrome (TRAPS).
- #18 Familial Mediterranean feverhttps://dermnetnz.org/topics/familial-mediterranean-fever
The most common reason for failure to respond to colchicine is poor compliance due to gastrointestinal upset. However, 5-10% do not respond to colchicine and this may be due to ABCB1 gene polymorphisms affecting colchicine uptake by mononuclear cells. […] Thalidomide and biologic agents, such as daily subcutaneous anakinra (an interleukin-1 receptor antagonist) or etanercept, may then be considered to prevent attacks and the development of amyloidosis. To reduce the severity of an attack, single-dose methylprednisolone or anakinra at the start of episodes have been reported to relieve symptoms.
- #19 Familial Mediterranean Fever – StatPearls – NCBI Bookshelfhttps://www.ncbi.nlm.nih.gov/books/NBK560754/
Patients with a more complicated disease such as frequent attacks or presence of amyloidosis can be given higher doses (2 to 2.5mg) as tolerated by the patients and if the liver and kidney function are normal. […] Compliance with the treatment must be addressed strongly to the patients since it is a common cause of lack of response to the therapy. […] If patients are still not responding to the treatment, then the dose of colchicine should be increased. […] IL-1 inhibitors are the second-line drugs for the patients who have colchicine resistant FMF or who have an intolerance to colchicine. […] Other drugs […] Tumor necrosis factor (TNF)-alpha inhibitors thalidomide, infliximab, and etanercept (a biologic TNF inhibitor that binds both TNF-alpha and TNF-beta) have also been described in some cases, but the real efficacy is still not established. […] Colchicine prevents the development of amyloidosis, so patients who have never been on colchicine or patients who present late in the disease process have higher chances of developing amyloidosis.
- #20 Frontiers | Familial Mediterranean Fever: Recent Developments in Pathogenesis and New Recommendations for Managementhttps://www.frontiersin.org/journals/immunology/articles/10.3389/fimmu.2017.00253/full
Familial Mediterranean fever (FMF) is the most common monogenic autoinflammatory disease (AID) affecting mainly the ethnic groups originating from Mediterranean basin. […] Recently, an international group of experts has published the recommendations for the management of FMF. Colchicine is the mainstay of FMF treatment, and its regular use prevents attacks and controls subclinical inflammation in the majority of patients. […] Colchicine is the mainstay of FMF treatment, and its regular use prevents attacks and suppresses chronic subclinical inflammation. […] Anti-IL-1 drugs emerged as promising treatment options in patients who fail to response or tolerate colchicine. […] The EULAR recommendations emphasize that the aim of FMF treatment is obtaining the control of acute attacks, minimizing the chronic and subclinical inflammation, preventing complications, and providing an acceptable quality of life.

There’s no cure for familial Mediterranean fever. However, treatment can help relieve symptoms, prevent attacks and prevent complications caused by inflammation. […] Medications used to relieve symptoms and prevent attacks of FMF include: […] Colchicine (Colcrys), taken in pill form, reduces inflammation in your body and helps prevent attacks and the development of amyloidosis. […] For people whose signs and symptoms aren’t controlled with colchicine, medications that block a protein called interleukin-1, which is involved in inflammation, may be prescribed. Canakinumab (Ilaris) is approved by the U.S. Food and Drug Administration (FDA) for FMF. […] Colchicine is effective in preventing attacks for most people. To lessen the severity of symptoms during an attack, your health care provider may recommend intravenous fluids and medications to reduce fever and inflammation and control pain. […] Regular appointments with your health care provider are important to monitor your medications and your health.

Theres no cure for FMF, but treatments can prevent and relieve symptoms. […] Colchicine is a generic medicine that controls inflammation in FMF. Its taken as a pill once or twice a day. Colchicine can prevent FMF flares, but if you or your child is already having an episode, the drug wont treat it. Colchicine needs to be taken regularly to work. Flares can return if you miss even one dose. Children who take colchicine regularly can have a full, normal life with FMF. […] If colchicine doesnt work or your child cant tolerate it, drugs that block interleukin-1, a protein linked to inflammation in FMF, may help. These drugs include anakinra (Kineret), canakinumab (Ilaris), and rilonacept (Arcalyst). […] Nonsteroidal anti-inflammatory drugs (NSAIDs) and pain medications, or analgesics, may help relieve fevers or joint pain during a flare. […] With treatment, you can have a normal, full life with FMF.

Patients who have an inadequate response to colchicine but who cannot afford biologic agents may benefit from the addition of dapsone to colchicine. […] In patients whose conditions do not respond to colchicine, biologic therapy in particular, agents directed toward interleukin-1 (IL-1) may be effective. […] Rilonacept, given by once-weekly subcutaneous injection, has been shown, in combination with continuation of colchicine, to reduce the number of attacks in patients who did not respond optimally. […] A systematic review found that in patients who do not respond to colchicine or cannot tolerate it, anti-IL-1 treatment resulted in a complete response to therapy, without a single attack during treatment, in 76.5% of patients treated with anakinra and 67.5% of those treated with canakinumab.

Anti-interleukin-1 agents are safe and effective treatment options among patients with familial Mediterranean fever. […] Treatments aim to suppress recurrent attacks and ongoing inflammation. […] Our meta-analysis showed that anti-IL-1 agents provided significant improvement in laboratory outcomes of FMF patients by reducing ESR and the level of CRP. […] Pooled data demonstrated that 60% (95% CI, 49%-72%) of adult patients and 81% (95% CI, 72%-89%) of pediatric patients achieved complete remission of attacks with anti-IL-1 treatment. […] A total of 93% (95% CI, 87%-99%) of adult patients and 91% (95% CI, 80%-103%) of pediatric patients had a more than 50% reduction in attack frequency. […] C-reactive protein (CRP) levels decreased after treatment with anti-IL-1 agents by 36.56 mg/L (95% CI, -52.96 mg/L to -20.16 mg/L) among adult patients and 50.6 mg/L (95% CI, -70.94 mg/L to -30.25 mg/L) among pediatric patients.

After colchicine has been started, EULAR recommends following patients closely for 36 months to observe the therapeutic effect. In patients who do not respond to twice-a-day dosing, administer colchicine three, or even four, times a day. […] In patients whose conditions were not responsive to oral colchicine, the addition of intravenous (IV) dosing 1 mg IV once a week reduced the number of attacks in 10 of 13 patients and the severity of attacks in 6 of 13 patients. […] Colchicine also stabilizes the amount of proteinuria in patients with amyloid nephropathy. […] A Turkish study found that in children who were heterozygous for MEFV variants and required initiation of colchicine treatment after experiencing symptoms of FMF, colchicine may be successfully discontinued in some cases, if very careful follow-up is provided.

For patients with established type amyloid A amyloidosis, anti-IL-1 treatment can even reverse proteinuria. […] Now, Tolga Yildirim, MD, PhD, associate professor of nephrology at Hacettepe University in Turkey, and colleagues present a case series that suggests that canakinumab is a useful first-line option for the treatment of renal transplant recipients with FMF. […] Their paper, published online Feb. 14 in the Journal of Nephrology, indicates that canakinumab has equal efficacy and better tolerability than anakinra in these patients. […] The authors report their three patients achieved a complete clinical response, including the elimination of attacks and normalization of serum C-reactive protein (CRP) levels. These benefits were achieved without significant side effects.

Periods of physical or emotional stress can trigger FMF attacks, and it may be worth temporarily increasing the dose of colchicine. […] There is neither agreement on the definition of adequate response nor consensus on the number of attacks per year that may be considered acceptable; this tolerability level should be judged in the context of the quality of life of the patient. […] Colchicine should not be discontinued during conception, pregnancy or lactation; current evidence does not justify amniocentesis. […] In general, men need not stop colchicine prior to conception; in the rare case of azoospermia or oligospermia proven to be related to colchicine, temporary dose reduction or discontinuation may be required. […] Chronic arthritis in a patient with FMF might need additional medications, such as disease modifying antirheumatic drugs (DMARDs), intra-articular steroid injections or biologics. […] If a patient is stable with no attacks for more than 5 years and no elevated APR, dose reduction could be considered after expert consultation and with continued monitoring.

Colchicine is taken to reduce or eliminate the number of painful attacks and eliminate the risk of kidney failure due to amyloidosis. […] Taking colchicine daily by mouth eliminates or greatly reduces the number of painful attacks in about 95% of people. Also, colchicine greatly reduces the risk of kidney failure due to amyloidosis. In pregnant women, colchicine helps prevent attacks that might lead to a miscarriage. […] If colchicine stops working or people are not able to tolerate it, other medications such as canakinumab, anakinra, or rilonacept, injected under the skin, may help. These medications modify how the immune system functions and thus help reduce inflammation. […] Ibuprofen or acetaminophen can be given to relieve pain and fever.

In general, men need not stop colchicine prior to conception; in the rare case of azoospermia or oligospermia proven to be related to colchicine, temporary dose reduction or discontinuation may be required. […] Chronic arthritis in a patient with FMF might need additional medications, such as disease-modifying antirheumatic drugs (DMARDs), intra-articular steroid injections, or biologics. […] In protracted febrile myalgia, glucocorticoids lead to the resolution of symptoms; NSAID and interleukin-1 blockade might also be a treatment option; NSAIDs are suggested for the treatment of exertional leg pain. […] If a patient is stable, with no attacks for more than 5 years and no elevation in acute phase reactants (eg, serum amyloid A protein, C-reactive protein), dose reduction could be considered after expert consultation and with continued monitoring.

In 2016, EULAR – The European Alliance of Associations for Rheumatology – published recommendations on the treatment of familial Mediterranean fever (FMF). […] The new work, published in the April 2025 issue of the Annals of the Rheumatic Diseases, includes 12 individual recommendations and four overarching principles. […] They also stress that the treatment goal is to achieve at least minimal activity and control of subclinical inflammation to prevent damage – and that this will require lifetime management and prophylaxis. […] The 12 new recommendations focus on key management steps, from first-line treatment with colchicine and dosing considerations through to second-line options and the biologic therapies that may be considered. […] EULAR and PReS are confident that this revised set of recommendations will support rheumatologists and other healthcare professionals in managing FMF in patients of all ages.

The treat-to-target (T2T) concept introduces treatment escalation and de-escalation depending on the achievement of numerical therapeutic targets. […] The aim of this initiative was to develop a T2T approach for the treatment of FMF that (i) unifies the plethora of available disease activity scores in the form of a multidimensional treatment target and (ii) takes into account the recent emergence of novel therapeutic agents. […] The proposed consensus treatment plan for the management of FMF incorporates multidimensional targets allowing transparent treatment decisions, which will promote personalised disease management and increase adherence to therapy. […] The developed consensus statements together with the level of agreement as well as the level of evidence and the grade of recommendation are summarised in Table 1.
