Familial Mediterranean fever (FMF) is a health issue that mostly affects people from the Eastern Mediterranean. It causes them to have fever and swelling that come and go. This leads to problems like joint pain and stomach ache.
The main reason behind FMF is gene mutations passed down in families. These mutations affect a protein called pyrin, which helps control the body’s inflammatory response. This is why people with FMF have more inflammation issues.
Diagnosis of FMF usually involves genetic testing. This testing looks for specific mutations in the MEFV gene, confirming if someone has FMF. Knowing this helps the doctors figure out the best treatment.
The usual way to treat FMF is with a drug called colchicine. It’s very good at lowering how often fever and inflammation happen. For many patients, it makes their life much better.
Doctors are also looking into stem cell therapy for FMF. This new treatment uses cells from the patient’s own body, like from the bone marrow or umbilical cord. The goal is to help fix the damage caused by the condition.
Stem cell therapy has shown some good results in FMF. It has helped to lessen the fever episodes and the swelling. This happens because the treatment affects how the body’s immune system acts and cuts down on inflammation.
Key Takeaways:
- Familial Mediterranean fever (FMF) brings about repeated fever and swelling episodes.
- It is caused by gene mutations that affect pyrin, a protein managing inflammation.
- Diagnosing FMF involves looking for key mutations in the MEFV gene through genetic tests.
- Colchicine is used to treat FMF by lessening these episodes’ frequency and impact.
- Stem cell therapy is a new potential treatment for FMF, aiming to heal tissues.
Clinical Manifestations of Familial Mediterranean Fever
Familial Mediterranean Fever (FMF) is a genetic illness. It shows up as fever and inflammation happen over and over. These problems mainly affect the serosal membranes, synovial joints, and skin. Inflammation in FMF means a lot of neutrophils are in the tissues that are having trouble.
FMF can be serious, causing a problem called systemic AA amyloidosis. This can hurt the kidneys and might even lead to death. FMF usually starts before someone’s 20, and the bad times can last from a half-day to three days.
Many of the changes that cause FMF are in the MEFV gene. This gene makes pyrin, which is very active in neutrophils. But we find it in monocytes and other cells too.
People in the Eastern Mediterranean aren’t the only ones with FMF changes. We see these changes in folks from Spain, Italy, Greece, Portugal, Kurdistan, and more. So, FMF’s reach worldwide is wider than seen at first.
More and more, we’re finding links between FMF and other inflammatory diseases. These could include Behçet’s and diseases that affect the digestive system.
To really ‘get’ FMF, we need to look at its causes and how it affects different cells. This means looking at inflammation, genes, and the roles of neutrophils and other cells in the disease process.
Clinical Manifestations of Familial Mediterranean Fever
| Manifestations | Description |
|---|---|
| Recurrent episodes of fever and inflammation | Key features of FMF, affecting serosal membranes, synovial joints, and skin |
| Influx of neutrophils | Neutrophils play a significant role in the inflammatory response in FMF |
| Systemic AA amyloidosis | A potential complication of FMF, leading to kidney failure and death |
| Onset and duration | FMF typically begins before the age of 20, with attacks lasting from 12 to 72 hours |
| MEFV gene mutations | Most FMF-associated mutations involve single amino acid substitutions in the MEFV gene |
| Pyrin expression | Pyrin, encoded by the MEFV gene, is most predominant in neutrophils but can also be found in monocytes, dendritic cells, and synovial fibroblasts |
| Global impact | FMF mutations have been identified in various populations worldwide, beyond the Eastern Mediterranean |
| Association with other conditions | FMF mutations may also be involved in non-FMF conditions like Behçet’s disease and inflammatory bowel disease |
Stem Cell Therapy for Familial Mediterranean Fever
Stem cell therapy is a new way to treat conditions like Familial Mediterranean Fever (FMF). It uses stem cells from bone marrow or umbilical cord blood. These cells help repair and grow new tissues. This could be a big breakthrough for those with FMF.
The first studies on stem cell therapy for FMF look promising. They have seen less severe symptoms and fewer episodes. The treatment seems to adjust the immune system and lower inflammation. It might not just help, but improve the lives of those with FMF.
Though this therapy gives hope, we need more studies. We must know more about how safe and effective it is for FMF. Still, using it with common treatments like colchicine might help. This mix could make managing FMF better for patients.
FAQ
Q: What is Familial Mediterranean fever (FMF)?

Q: What are the symptoms of FMF?
A: FMF shows up as fever, swollen parts of the body, and aches, especially in the joints and stomach.
Q: What are neutrophils and their role in FMF?
A: Neutrophils are soldiers in our body that cause swelling in FMF by going into the wrong places.
Q: Can FMF cause other complications?
A: Yes, it might lead to a serious condition affecting the kidneys.
