COVID-19 Related Laboratory Coagulation Findings

his presentation will cover the current status of laboratory testing for anemia. It will discuss novel hematological and biochemical markers which are clinically relevant for the differential diagnosis of anemias. The challenge of providing specialized testing for anemias will be discussed in conjunction with possible new diagnostic approaches. With the introduction of gene therapy for hematological disorders, there is now a renewed focus on hematological and biochemical markers which may help in define the level of response. Novel approached for Point-of-Care delivery of CBC will also be discussed.

Learning objectives

  • Appreciate the proper use of novel parameters in the diagnosis of hemolysis and anemia
  • Assess the value of novel technologies for near patient care CBC
  • Integrate multiple parameters to assess responsiveness to novel therapies in hemoglobinopathies

NEW QUESTION/ANSWER

It is common to see necrosis in cHL, hard to put a number on it offhand.

NEW QUESTION/ANSWER

Classic in the 2017 WHO

NEW QUESTION/ANSWER

It can be expressed in both CHL and ALCL so it may not be reliable.

NEW QUESTION/ANSWER

CD15, CD30, CD20, PAX5, OCT2, BOB1 and CD45 can be helpful.

NEW QUESTION/ANSWER

I have never seen this.

NEW QUESTION/ANSWER

No, there is no clinical role for this at present.

NEW QUESTION/ANSWER

This would be highly unusual

NEW QUESTION/ANSWER

I don’t have any experience with J chain but is usually negative in RS-cells. MUM1 is typically positive but not specific.

NEW QUESTION/ANSWER

No

NEW QUESTION/ANSWER

Yes. J-chain and MEF2B have been reported to be useful as well. PMID: 28851661

NEW QUESTION/ANSWER

I don’t think it is particularly helpful, some cases of cHL may have rearranged IGH

NEW QUESTION/ANSWER

No

NEW QUESTION/ANSWER

I don’t find it that helpful

NEW QUESTION/ANSWER

There has been some data to suggest it is prognostic.

NEW QUESTION/ANSWER

It does not appear to commonly result in loss of CD30 expression in follow-up biopsy but I don’t believe this has been extensively studied.

NEW QUESTION/ANSWER

Yes, for T-cell lymphomas including cutaneous T-cell lymphomas it is reasonable to report the % positive tumor cells because some trials that resulted in the approval of brentuximab used specific cutoffs.
