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...
Can liquid biopsy be substituted for tissue biopsy in a lung mass that is radiologically suspicious for primary lung cancer when CT-guided biopsy cannot be done?
Generally, the utility of liquid biopsy remains in the ability to provide genomic information from cfDNA. A liquid biopsy will not provide a definitive tissue diagnosis and does not provide information about histology. When a histologic diagnosis is made with biopsy or FNA but the sample is insuffic...
Do you stop treatment for a prostate cancer patient diagnosed with acute radiation proctitis with significant pain?
I would first check the treatment fields and treatment setup to ensure that there isn't excessive dose going to the anorectum. As with all toxicities in radiation oncology, one must exclude other possible reasons for the anorectal pain such as hemorrhoids, infection, or inflammatory bowel disease. I...
How do you counsel patients who are candidates for a clinical trial regarding their options?
I typically discuss the option with patients as early as possible in their diagnosis, and explain that at some point during their treatment they may become a candidate for a clinical trial. I discuss resources to look into clinical trials and what they mean for patients. We discuss patient website r...
