Had my 1st alloHCT recipient die from COVID-19 yesterday. Young but vulnerable from ongoing tx for relapsed AML. Got it from a family member at low risk for negative outcome...who got it from someone else at low risk. This is why we say

My greatest success story: 5.5yrs out from allo for prim refract monosomal karyo AML using TBI prep, treated >3yrs w pred/siro/ECP for sev-ext cGVHD, now 35wks pregnant with a medically assisted pregnancy using a donor oocyte!! And an absolute delight!❤️ (Posted with permission.)

My thoughts exactly. He’s probably getting convalescent antibodies today and would get remdesivir/dex at earliest possible indication of progressive lower airway disease. His course will absolutely not be representative of what the public at large faces.

Academic medical centers are headed for a staffing crisis. Too many faculty are burned out, feel unsupported, & there are other options. I’m not going anywhere, but have heard about too many w imminent changes afoot to not be shook. And that’s just the docs. RNs are bailing too.

I lost one of my favorite patients of all time today. :( Though much younger, she taught me so much. Some face their adversity w bravery I know I’d never muster... It both inspires and breaks me to bear witness to such struggles. None of what we do is easy. Some of it is harder.

Not so fast. Spleens exist to satisfy hematologists — by recommending their removal. Appendices exist to give surgeons a starter procedure to practice — so they can grow up do the big ops, like laparoscopic splenectomies in patients with platelet counts in the single digits.

I lost a [late 20s]yo patient today who I’ve taken care of for about 2yrs (through 2 malignancies and an alloHCT). Worse, her parents lost their baby at far too young an age. No parent should have to see their child go first...

Today proved to me once again that getting a patient with ALL to a CAR-T cell therapy is a very, *very* difficult needle to thread. Days matter in this disease. If ever this is to become more common therapy, our systems must become more nimble (or we need off the shelf options).

A career in BMT/CT is richly rewarding, but what we do, especially alloHCT is very specialized and legitimately requires additional training beyond standard Hem/Onc training. Patients deserve competency. Competency comes from adequate training and exposure. That’s just a reality.

I no longer transplant Ph+ B-ALL pts if they tolerate hCVAD+ponatinib and achieve CMR. Ph+ B-ALL should no longer be considered high risk when treated with this specific regimen and fewer patients should be subjected to the toxicity of alloHCT. This is the way.

Stem cell grafts must fly. They did on 9/11. We must find a way now... If blood cancer patients have to delay or defer transplants (or can’t get peritransplant care when systems are overwhelmed) many of them will be among the collateral casualties of COVID-19.
