Is Mediterranean fever hereditary?
Familial Mediterranean fever is caused by a gene change (mutation) that’s passed from parents to children. The gene change affects the function of an immune system protein called pyrin, causing problems in regulating inflammation in the body.
How is familial Mediterranean fever inherited?
Familial Mediterranean Fever (FMF) is an autosomal recessive inherited disease, which means it appears only in individuals who received two copies of the mutant (altered) gene that causes FMF, one from each parent.
What does it mean to be a carrier of familial Mediterranean fever?
Familial Mediterranean fever is an autosomal recessive disease caused by mutations in the MEFV gene. 1 An individual who inherits one copy of an MEFV gene mutation is a carrier and is typically not expected to have related health problems.
Is Familial Mediterranean Fever an autoimmune disease?
Overview. As opposed to an autoimmune disease in which the immune system attacks its own cells, FMF is an autoinflammatory disease in which the innate immune system (the body’s first-line defense) simply doesn’t work as it is should.
What causes FMF flare ups?
FMF flares may be triggered by an infection, stress, strenuous exercise, physical trauma, or even getting your period. Between flares, people with FMF often feel normal. They may be symptom-free for years between flares.
How is FMF treated?
Initial treatment of FMF is with colchicine. Colchicine — Colchicine is primarily effective as a prophylactic treatment for the FMF attacks. It is recommended in all patients regardless of the frequency and intensity of attacks.
Is FMF a rare disease?
Although considered a rare disease, it is possible that its diagnosis has been delayed in some countries such as Japan [5]. Molecular genetic diagnostic testing is often used to provide some information on FMF diagnosis [6].
Why is colchicine used for FMF?
Colchicine has been the main treatment of FMF since 1972 [26]. Colchicine is related to pyrin through altering the organization of actin cytoskeleton by binding to tubulin monomers and inhibiting polymer formation [27, 28].
What medications should be avoided in Mediterranean Fever?
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 …
What are the side effects of colchicine?
Diarrhea, nausea, cramping, abdominal pain, and vomiting may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
How do you manage FMF?
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.
What does it mean if a disease is familial?
A familial disease is hereditary, passed on from one generation to the next. It resides in a genetic mutation that is transmitted by mother or father (or both) through the gametes to their offspring. Not all genetic disorders are familial, however, because the mutation may arise…
What causes familial Mediterranean fever (FMF)?
Familial Mediterranean fever (FMF) is a rare disorder passed down through families (inherited). It involves repeated fevers and inflammation that often affects the lining of the abdomen, chest, or joints. FMF is most often caused by a mutation in a gene named MEFV. This gene creates a protein involved in inflammation.
What are the symptoms of Mediterranean fever?
Fever
Is familial Mediterranean fever contagious?
Familial Mediterranean Fever (FMF) is an inherited disorder, not an infectious one. It is a clinical diagnosis that can be confirmed by a gene mutation in the majority of cases. FMF is diagnosed in children with episodic fevers, often with pain in the abdomen, joints, or chest. The fever of FMF is not contagious.
