Understanding Immune System Recovery Post Follicular Lymphoma Treatment

Understanding Immune System Recovery Post Follicular Lymphoma Treatment from Patient Empowerment Network on Vimeo.

Follicular lymphoma treatment may impact the immune system in different ways. Expert Dr. Kami Maddocks from The Ohio State University Comprehensive Cancer Center discusses how immune function may be impacted and how recovery is monitored.

So another person is asking, “How long does it take for the immune system to really start bouncing back after follicular lymphoma treatment? And what blood test results indicate a weakening immune system?”

Dr. Kami Maddocks:

Yeah, so this is a great question. It also can be a complicated question with many different answers. So one, it can depend on the treatment that a patient receives. Two, it can actually depend on their different parts to the immune system. So different parts of the immune system can recover at different time periods from treatment. So acutely, our neutrophils are something that often gets…they’re bacteria infection fighting cells. Those are the cells that during chemotherapy, when that count gets low and patients are counseled on if you have a fever during your treatment, you need to be evaluated and be seen because if you have an infection and a fever during chemo or some of these treatments, your blood counts are low, you might need to be in the hospital on IV antibiotics.

So those neutrophil parts of it are usually quicker to recover, so they drop with treatment and then recover pretty quickly with each cycle, including after an ended treatment cycle. Sometimes when patients have been treated with several different therapies, it can be harder for those cells to recover. They can stay lower for longer. Then there’s a component of the immune system, so we are ripping out the lymphocytes, because that’s what the cancers have.

And so things targeted. Chemotherapy in general kills the lymphocytes, but there also are targeted therapies like rituximab (Rituxan) bispecific antibodies CAR-T cells, those are particularly wiping…targeted towards proteins on the lymphocytes and wiping them out. Those can be for a more prolonged time. In general, we usually think of about a six-month period so patients can be at increased risk for viral infections in that six-month period may not respond as well to vaccines in that period.

But for some patients it takes longer and some patients recover quicker. It also can depend on where patients are at in their journey because every therapy that they’ve had can take a little bit longer to recover. The last part I’ll add is just sometimes when the lymphocytes are wiped out for a long time people’s proteins, their immunoglobulins that help fight infection get low. And so sometimes we actually will end up giving patients replacement of IVIG to help if they’re having lots of infections.

Katherine:   

Are there other side effects that patients should know about and side effects that they might experience?

Dr. Patel:  

Yeah, so neurotoxicity is one that we don’t see as much as we see in lymphoma patients, which is again great but sometimes people can get something called ICANS, which is a type of neurotoxicity in the first 30 days after CAR T.

And basically, it can be as bad as seizures, but thankfully we don’t see that very often, or I haven’t seen it at all. But it can cause confusion. It can cause people to be extra sleepy. So, we have different treatments that we give to turn that around. Longer term, really, the big side effects are the counts being low. So, what we call cytopenias. So, white count, hemoglobin, platelets.

And so, that is something we see quite often in our patients who have had a lot of therapy for myeloma already, and then are getting something like CAR T.

So, a lot of my patients will still need transfusions even a month or two or three after, and we’re giving GCSF to help their white count come back up, et cetera.

Katherine:    

What’s that?

Dr. Patel: 

So, G-CSF is basically a growth factor that helps your neutrophil; so, a different type of white blood cell – come back up, which helps fight against bacterial infections.

So, it’s the same medicine for anyone who’s had a stem cell transplant. It’s the same medicine you get to get your stem cells into your blood but it’s at a lower dose. But again, it’s to avoid infections, to help present bacterial infections. The other one is infections can also be caused because of low IgG levels or what we call immunoglobulins; these are our antibodies that we have.

And the good news is, when CAR Ts or bispecifics or some of these immune therapies work really well, they’ll kill as many myeloma cells as we possibly can.

But they also kill good cells. So, they kill good plasma cells that make us antibodies and good B cells that make us antibodies. So, when that happens, people’s IgG levels will go down and that puts you at risk for infection too. So, we actually aggressively give people IVIG to help prevent those infections.
