Dr. Bruce Blazar presenting the E. Donnall Thomas lecture this year at #ASH22. @JaneWinterMD shares that his lab continues to bring new technology to preventing GvHD. 1/n
Humbly introducing Dr. Thomas and his contributions. (from his 1957 NEJM paper showing you could have natural acquired immunologic tolerance and radioprotection could induce graft tolerance!) Already feel like this #story is going to be so amazing. #ASH22 2/n
Cadaveric transplants! And then in the next 10 years 203 patients got BMTs and died but he pressed on! Then in 1961 they did a identical twin transplant for aplastic anemia! and then Dr. Thomas got the Nobel prize in 1990! 3/n #ASH22
Next up we learned that you could T cell removal could spare mice from Graft vs Host disease. Moving on to Dr. Blazar's chapters of the story 4/n #ASH22
Love showing #ASHtrainees that we often have to revise our plans! Then they found there was more graft failure with the T cell depletion studies (apparently it took 24-36 hours to do this on the samples!) #ASH22 5/n

Two oral abstracts on the #STELLAR study (Sickle Cell Transplant Evaluation of Long-term and Late Effects Registry) presented by Dr. Sobenna George (hi!) and Dr. Lillian Meacham #ASH22 1/n
What's the problem? You can get DOR = diminished ovarian reserve or POI = primary ovarian insufficiency (early menopause). This is SUCH a good explanation!! #ASH22 2/n
Small numbers but such great data, 30 females and 18 males, about 4-6 years post therapy (myeloablative transplants (mostly matched sib) and one each with gene tx) #ASH22 3/n
They looked at 5022 patients with Rx of DMTs. Those on DMTs were surprisingly mostly in the 18-45 group (the box is wrong on the screenshot) and mostly male and had more VOCs. #ASH22 3/n
Management of pregnant women with #SCD in high income countries with Dr. Eugene Oteng-Ntim (with the cutest intro from Dr. Eugenia Asare). Writing down the #pearls here so I can share with my patients for their future and so I can advocate for them. #ASH22 1/n
As we know, more low/not detectable AMH levels in women with #SCD. Know that preimplantation diagnosis and successful transfer is possible with data to support that. And many want #NIPT secondary to fear of amnio or CVS, which can be done. (w/ @nonacus) #ASH22 2/n
What risks are we talking about in sickle cell disease and pregnancy? 1/4 of the patients in their cohort required transfusion during pregnancy and RR of preeclampsia is 2.43 and 3x risk of SGA, 4x risk of stillbirth. #ASH22 3/n
Dr. Mark Fleming talking about pathology vs molecular testing in MDS. He first reminds us the difference of childhood MDS from adult MDS -- and these WHO guidelines, childhood MDS is only classified into these two subtypes. #ASH22 1/n
The issue is that the "dysplasia" definition has been defined by the cytogenetic abnormalities and genotypes of adult MDS so the criteria for blast %age, extent of dysplasia -- but does this apply?? #ASH22 2/n
MDS in pediatric patients is more normo or hypocellular than hypercellular. There is not ringed sideroblasts in persons <30 and he also reminds us that there are a number of baseline dysplasias in germline BMF pts that are mistaken for MDS! #ASH22 3/n
#ASH22 Bone marrow failure syndromes: diagnostic principles in 2022. Starting with Sara Lewis, a genetic counselor in hematology. Follow this tweet for more. 1/n
Sara reminds us that she feels patients think more about their family history as they see her draw the pedigree. Time for me to start doing this! #phodocs#ASH22#pearl 2/n
Here are the options for diagnostic workup - genetic tests can be done from somatic genes or germline! #ASH22 3/n
@bhwords Dr. Beverley Hunt presenting on #COVID19 and #thrombosis. She wants to chronologically review the battles we have fought! #ASH22 1/n
@bhwords This story (clinical presentation) -- a reminder of the patients from the front lines in the beginning and what some docs went through! #COVID19#ASH22 2/n
@bhwords#COVID19 is the 'perfect suit for VTE' ... inflammation, sticky blood, vessel wall changes. The amazingly high levels of fibrinogen (14g/L! (normal is 2-4g/L)) D-dimers reported on a log scale because of the significant increase. #ASH22 3/n
