dr. leber also notes that while a normal red blood cell lives for three to four months, with an enlarged spleen, that time can dwindle to just one month due to the spleen’s role in red blood cell clearance. “the function of the spleen also contributes to the anemia,” he says.
mf affects more than blood counts and spleen size — it also drives systemic inflammation. “people can have widespread, systemic side effects,” says dr. leber. “some patients have the same degree of inflammation as somebody with severe untreated rheumatoid arthritis. there can be unintentional weight loss, bone pain and loss of appetite.”
mf is quite rare, making diagnosis challenging. while there’s no national mf registry, data suggests that the number of patients with mf in canada might be around 2,000, according to dr. leber.
living with myelofibrosis
for james, navigating life with mf has meant making adjustments. being a partner in his firm, he has no plans to quit working. “i’ll never retire,” he says. days at the office look a little different now, however.
“the only real symptom i find now is being very tired,” says james. “i’m lucky to have a couch in my office, so i can take a nap when i need to.”
james is also anemic (usually defined as a hemoglobin value of less than 135 g/l in adult men), which can contribute to fatigue. “my hemoglobin got down to 90 g/l,” he explains,” and once it gets down to around 70 g/l, my doctors say i may need a blood transfusion.”
