Is there a role for anti-neutrophil antibody testing in the workup of neutropenia?
In my view, anti-neutrophil antibodies add little to the work-up of neutropenia. Drs. @Dr. First Last and @Dr. First Last presented an abstract at ASH in 2015 that summarized restyles for 60 pediatric persons with a diagnosis of autoimmune or idiopathic neutropenia. The sensitivity and specificity o...
What are the benefits of sending HLA B27 genotype over HLA B27 antigen when evaluating for spondyloarthritis?
HLA-B27 is strongly associated with ankylosing spondylitis (AS) which is an inflammatory rheumatic disease that affects the spine, the sacroilliac joints, and peripheral joints. It is also associated with other diseases like acute anterior uveitis, inflammatory bowel disease, or psoriasis. HLA-B27 t...
How would you manage a patient with type 1 cryoglobulinemia secondary to MGUS?
Rituxan can be tried if IgM type MGUS. Please find the attached ASH article on How I treat cryoglobulinemia by Muchtar, Magen, and Gertz; PMID 27799164.
Is there a role for measuring hydroxychloroquine blood levels in clinical practice?
This is being actively investigated by a number of groups around the world, with no final consensus, but the groups in France have studied this the longest, and published the most, to date. The major outcome has been that some (quite a few) patients had very low levels, who admitted on careful quest...
How does a history of splenectomy alter how you counsel patients on the infection risk of TNF inhibitors or other biologics?
In general, a history of splenectomy would lead to an increased concern regarding infections with parasitemia and encapsulated organisms (particularly Strep. pneumoniae, Haemophilus influenzae type b, and Neisseria meningitides). However, I would not consider prior splenectomy an absolute contraindi...
How do you approach a patient found to have a coronary lesion suggestive of vasculitis on coronary CT?
I am not sure what findings are considered “suggestive of vasculitis on coronary CT”. Vasculitis in the coronary arteries is quite rare but can be seen in several vasculitides. There is a big difference in seeing angiographic changes atypical for atherosclerosis (which I assume is what is meant by t...
What is considered an adequate treatment period to assess response of AAV induction therapy with rituximab or cyclophosphamide?
This is an issue of considerable interest both clinically and for research studies, and the approach to both settings is currently similar: are there any signs or symptoms of ongoing active disease? The key words being “ongoing” and “active”. The expectation once glucocorticoids are started and then...
Do you approach the diagnosis and treatment of HIT patients differently in the outpatient setting or in a resource-limited community setting?
The concern for heparin induced thrombocytopenia is a complex problem. If the patient has HIT by 4T score and thrombosis, then admission to the hospital for initial management including direct thrombin inhibitor is the correct path awaiting confirmation by ELISA and platelet release assay. If negati...
How will you counsel patients receiving radiation therapy regarding COVID-19 vaccine administration?
Encourage to take the vaccine as scheduled (both during or after RT).
How do you workup erythrocytosis with a normal or elevated serum erythropoietin?
First, I would consider using the term erythrocytosis rather than polycythemia. Too often, use of the term polycythemia may suggest polycythemia vera (PV) (a malignancy) rather than something more benign.The recommended up front testing in the evaluation of erythrocytosis consists of up front JAK2V6...
