Dear Keith,
I'm so pleased you're feeling ok. I only know a little about all the parameters in a blood test – too low hemoglobin and you run out of puff, platelets too low and you can bruise easily, neutrophils too low and you can catch bugs. The way our bone marrow works gets compromised by all the treatments, and I suspect that even a doctor cannot say with certainty what is causing what. I think that both Rev and Thal can lower neutrophil levels. I do know that when neutrophils go below 0.5 then you are at real risk of catching things. One additional parameter to look at is what level your immunoglobulins are: for example if your myeloma is IgG, then your 'good' IgG may be suppressed, as well as your IgM and IgA. A doctor can advise you whether these have fallen so far that you are at greater risk. In some countries patients get intravenous immunoglobulins each month to boost their immunity: I'm not sure that the NHS will be too keen on providing that service at the moment. Always worth a try.
Anyway keep us posted. I'm due a blood test tomorrow – still on Thal and a bit alarmed by all the words I'm forgetting when I try to explain something. Surely I haven't aged that fast?
Best,
Eva
