You can actually have infusions of IgA, contrary to the info provided above by the Myeloma Team.
However it is quite risky and only done under specific circumstances of severe immune deficiency or non-responding infections, and specific criteria regarding immune function and any anti-IgA antibodies that may be present

It is a complicated subject. You should clarify with his hematologist whether it is IgA infusion, or is he/she referring to the type of MM.

Judy,
I have IgA Kappa. Is that what your husband has? Check out the Multiple Myeloma Research Foundation website. HTTPS://www.themmrf.org
They also have counselors you can talk to.

It sounds like the question is: Why would an oncologist factor IgA into the treatment plan for myeloma?

IgA is actually a *type* of myeloma, not something added to treatment. When myeloma is classified as IgA, it means the abnormal plasma cells are producing a specific type of protein called IgA immunoglobulin. IgA myeloma Show Full Answer

It sounds like the question is: Why would an oncologist factor IgA into the treatment plan for myeloma?

IgA is actually a *type* of myeloma, not something added to treatment. When myeloma is classified as IgA, it means the abnormal plasma cells are producing a specific type of protein called IgA immunoglobulin. IgA myeloma tends to behave differently than other types, which is why it matters for treatment planning. Here's what makes it distinct:

- It's generally considered more aggressive than other types, like IgG myeloma
- It has a higher risk of relapse after treatment
- It's more commonly linked to genetic changes that can make the cancer grow faster or resist treatment
- Myeloma cells in IgA cases are more likely to spread outside the bone marrow

Because of these factors, an oncologist may recommend a more aggressive or tailored treatment approach to stay ahead of the disease.

It's always worth asking your oncologist directly why they're recommending specific treatments — they can explain how your IgA classification is influencing their decisions for *your* particular case.
