Red Blood Cell Contribution to Thrombosis in Polycythemia Vera and Essential Thrombocythemia

Julien Grenier, Wassim El Nemer, and Maria De Grandis

Polycythemia vera (PV) and essential thrombocythemia (ET) are myeloproliferative neoplasms (MPN) characterized by clonal erythrocytosis and thrombocytosis, respectively. The main goal of therapy in PV and ET is to prevent thrombohemorrhagic complications. Despite a debated notion that red blood cells (RBCs) play a passive and minor role in thrombosis, there has been increasing evidence over the past decades that RBCs may play a biological and clinical role in PV and ET pathophysiology. This review summarizes the main mechanisms that suggest the involvement of PV and ET RBCs in thrombosis, including quantitative and qualitative RBC abnormalities reported in these pathologies. Among these abnormalities, we discuss increased RBC counts and hematocrit, that modulate blood rheology by increasing viscosity, as well as qualitative changes, such as deformability, aggregation, expression of adhesion proteins and phosphatidylserine and release of extracellular microvesicles. While the direct relationship between a high red cell count and thrombosis is well-known, the intrinsic defects of RBCs from PV and ET patients are new contributors that need to be investigated in depth in order to elucidate their role and pave the way for new therapeutical strategies.

A Parent’s Story: Navigating the Health Insurance Maze

I know there are good people who work at insurance companies, however, some are the bane of my existence. Every month I gear up for the fight to get my son, Jedi, his medicine. Jedi has an MPN. My hope is that my journey can be used to make this process easier and better for other patients and their families.

Hydroxyurea was the initial drug prescribed for my son. It wasn’t a difficult drug to get filled, even though it was a little overwhelming walking my son through the adult oncology unit at MD Anderson Cancer Center, to the “specialty pharmacy.” It was frightening for him to see adults that look so sickly skinny and with their bald heads from their treatments. However, the real frustration began when he was put on Pegasys. MD Anderson tried to call numerous pharmacies to his prescription filled, but they were unable to find a pharmacy that had it in stock. So we left the hospital with a handwritten script in search of the drug.

At that time, we were insured by United Health Care. This was my first introduction to a specialty drug. For background purposes, specialty drugs are a recent designation of pharmaceuticals that are classified as high-cost, high complexity and/or high touch, such as injectables. A chemotherapy that is administered orally, like Hydroxyurea, is covered as part of a normal prescription. A chemotherapy that is administered as a subcutaneous (jiggly fat) shot, like Pegasys, is not. In other words, it comes out of your deductible. For us, that means we owed approximately $4,000 for the first month of Pegasys. We had to prove to the insurance company that Pegasys had been approved for polycythemia vera. This was done by producing a memo my husband found on the internet from United Health Care specifically stating Pegasys was approved for polycythemia vera.

Then, our insurance was switched to Blue Cross Blue Shield of Texas (BCBSTX). (I will skip the conversation about trying to get our member number early so I could start the pre-approval process.  I had been told in a Facebook group that it took about six weeks to approve Pegasys with BCBS. This was cause for concern because we could only get four weeks of medicine at a time.)

I started the pre-approval process with BCBS after we received a member ID number the first week of January. As expected, Pegasys was initially declined.  In the state of Texas I should be able to submit an emergency appeal and get a response in three days, but I had to get the appeal submitted first.  It is very difficult to get the appeal started. Not to mention that BCBSTX outsources the pharmaceuticals to Prime.

After a few weeks of deep frustration and the looming possibility we could run out of his medication, I finally posted the following on Blue Cross Blue Shield of Texas Facebook page:

January 15, 2019. Your appeals process is TERRIBLE. I have spent HOURS trying to figure this out. I have a 10 year old with CANCER. His medicine is out next week. I have to get it from a specialty pharmacy. His doctor called BCBS yesterday (a number I got after spending TWO HOURS on the phone last Friday) and was told that he has to wait 7-10 business days to start the process. Today I received a NEW peer-to-peer phone number. Does this start the process? No, it sets up an appointment for our doctor to talk to your doctors. Just to give you an idea. This medicine controls platelets. If his platelets go up he could have a heart attack, stroke, embolism for example. You can see my concern. My next steps are to ask my doctor to call AGAIN to START the appeals process – you know the one he tried to start yesterday? I will also have on my TO DO list to file a complaint with Texas Department of Insurance, contact my state Senator and Representative. Thank you for making this such a HARD process. Oh, by the way, the National Comprehensive Cancer Network, other BCBS insurance (different states), United Healthcare ALL have approved this medicine for his diagnosis

 I received a phone call from BCBSTX within 24 hours of posting this. I was told I had made it to the “special escalation” team because I posted on social media. On one hand, I am grateful he was approved. On the other hand, I am sad that this is what it took. I think it also helped that I had gathered the information to make it easy for them to approve. I had whitepapers, Jedi’s medical records and the details from the National Comprehensive Cancer Network. (Click here to view).

I wish I could say this was the end of the drama. But this is a story for another day. Just writing this was overwhelming. I can’t imagine what people who are sick go through. I am the caregiver, not the patient. I do not have chemo brain and I am exhausted by the process and the stress and anxiety to ensure my child receives his treatment. I hope this information will help other families move through the process a little more smoothly and I will continue to write about the trial and tribulations I experience on my website.

Caregiving: What I’ve Learned

By Stephen W.

My wife was diagnosed with ET (Essential Thrombocythemia) in 2007. Since then, her health issues have varied. For several months, she will do very well with little to no problems, and then an episode that has included an ER visit on occasion, will throw us into action mode. Even our children know what is expected of them. We all becoming a caregiving team.

Caregiving has many layers. It requires endurance, listening skills, humility, open mindedness, flexibility, wisdom, empathy, managerial skills, problem solving skills, healthy choices, rest, outlets, support and in many ways, the needs similar to those we care for, except that we have to be willing to be the strength BEHIND the patient.

Endurance. There will be days when the one you are caring for requires everything you’ve got. It is easy to get burnt out. You may find yourself doing it all and feeling a bit resentful, at times. My suggestion is to get a backup caregiver. So many people offer help and we graciously decline with a thank you and assurance that we are okay. I now say, thank you and how can you help? Getting help doesn’t mean you are shrugging your responsibilities or care less about your loved one. It is a wise decision when times are tough. Sometimes just having someone grocery shop is a great gift.

Humility. Caregiving is not about you. I’ve learned to keep my place and learn from my wife and those that administer her medical care. I don’t have all the answers. My role is vital but there is no room for an ego.

Managerial skills. I never dreamed the managerial skills I learned in my career would come in handy for caregiving. Managing appointments, medical needs, insurance companies, children, household needs, and day to day care for the patient can be overwhelming without a system. When times are tough we run a tight ship with each of us knowing our role and responsibilities. Delegating is a way of life. We’ve learned to adjust quickly and as needed.

Keeping EVERYONE healthy. Parenting and caregiving for an adult are very similar. If we aren’t healthy, everyone suffers. Proper nutrition, exercise, rest, and finding outlets and support are essential. Recognize when you need a break and take it.

The Rewards. I’ve never felt closer to my wife. Our family is stronger and we know we can rely on one another. I’ve learned a lot about ET, but equally about life and love.
