Key Points about Myelofibrosis
- Definition: Myelofibrosis is a rare bone marrow disorder where the marrow is replaced by fibrous tissue, leading to ineffective blood production and enlargement of the spleen (splenomegaly).
- Causes:
- Primary myelofibrosis (idiopathic).
- Secondary to other myeloproliferative disorders, such as polycythaemia vera or essential thrombocythemia.
- JAK2, CALR, or MPL gene mutations.
- Symptoms:
- Fatigue and weakness due to anaemia.
- Splenomegaly causing discomfort or pain in the upper abdomen.
- Fever, night sweats, and weight loss (constitutional symptoms).
- Investigations:
- Full blood count showing anaemia, leukopenia, or thrombocytopenia.
- Bone marrow biopsy revealing fibrosis.
- Genetic testing for JAK2, CALR, or MPL mutations.
- Management:
- Symptomatic treatment: blood transfusions for anaemia, medications like ruxolitinib to reduce splenomegaly.
- Stem cell transplant in younger or fit patients as a potential cure.
- Supportive care and monitoring for disease progression.
- Complications:
- Progression to acute myeloid leukaemia (AML).
- Severe anaemia and recurrent infections.
- Bone marrow failure leading to pancytopenia.
