Jan Gersta Waldenstrom (April 17, 1906 – December 1, 1996) was a Swedish physician who first described the disease that bears his name, Waldenstrom’s macroglobulinemia.

When was Waldenström’s macroglobulinemia detected?

The gene was found in 1993, and a molecule designed to shut it down has been lurking on lab benches since the late 1990s. Treon led a clinical trial of the BTK inhibitor Imbruvica in 63 previously treated patients with Waldenstrom’s macroglobulinemia.

How rare is Waldenström’s macroglobulinemia?

Waldenstrom macroglobulinemia (WM) is rare and occurs at About 3 cases per million people per year In the U.S. In the United States, approximately 1,000 to 1,500 people are diagnosed with WM each year.

How did Waldenstrom get its name?

These abnormal cells produce excess amounts of IgM, a protein called immunoglobulin; the overproduction of this large protein is what gives the condition its name (“Macroglobulinemia »).

Is WM hereditary?

genetic. genetics Seems to play a role at least in some people who get WM. About one in five people with WM has a close relative with WM or a related B-cell disorder, such as MGUS or certain types of lymphoma or leukemia.

What Causes Waldenstrom’s Macroglobulinemia?

What Causes Waldenstrom’s Macroglobulinemia (WM)?Doctors don’t know the cause of WM, but think it involves Gene mutationA recent study found that WM cells have mutations (changes) in a gene called MYD88, which normally helps immune system cells signal each other and helps them stay alive.

Was Waldenstrom lethal?

The cumulative probability of progression to symptomatic WM, amyloidosis, or lymphoma is 1 year 6%, 39% at 3 years, 59% at 5 years, and 68% at 10 years. The main risk factors for progression are the percentage of lymphoplasmacytic cells in the bone marrow, the size of serum M-spike, and the hemoglobin value.

Does Waldenstrom hurt?

If M protein thickens blood only in cooler parts of the body, such as the tip of the nose, ears, fingers, and toes, it’s called cryoglobulin. Cryoglobulin can cause pain or other problems In these areas if a person is exposed to cooler temperatures.
