Do you perform genetic testing when patients have persistent hypogammaglobulinemia after rituximab therapy?
I would not routinely perform genetic testing. Multicenter studies (Labrosse et al., PMID 33862010; and Otttaviano et al., PMID 35892275) show that genetic testing returns a low yield, <5%. Several authors suggest that the risk of persistent hypogammaglobulinemia due to PID is increased if there is ...
Do you escalate treatment in patients with myositis who achieve clinical remission but continue to have elevated CPK?
Typically, patients who are doing well and in remission can have low levels of CK abnormality, which needs to be monitored but not treated. Post myositis improvement, some patient's muscle membrane remains leaky or not perfect, leading to some low levels of elevated CK, which has no clinical signifi...
What is your approach to timing of medications like Rituximab and Cyclophosphamide around plasmapheresis in patients on daily PLEX?
Plasma exchange (PLEX) in designed to remove antibodies. Thus, PLEX will remove monoclonal antibodies, including rituximab, and do so fairly effectively and likely to some extent in proportion to the intensity of the PLEX. If there is a clinical need to use PLEX for a patient also to be given rituxi...
When would you consider discontinuing immunosuppressive treatment in a quiescent uveitis patient without systemic manifestations of inflammation?
I typically monitor patients on immunosuppressive therapy for at least 2 years before considering stopping or weaning off such therapy. There could be exceptions to this, including patients who insist on being taken off their meds (side effects, trying to conceive, etc.), in which case I can try aft...
How can we approach tapering or discontinuing biologic DMARDs in patient in their 80s with well controlled rheumatoid arthritis?
Not a simple answer, unfortunately, as we know Rheumatoid arthritis (RA) is a chronic disease and thus requires long-term treatment!If, however, the patient's preference is to taper or discontinue a biologic DMARD, per ACR RA treatment guidelines, it can be considered after the patient has been in r...
When discontinuing Denosumab after more than 2-3 years of therapy, when do you recommend giving the first dose of zoledronic acid?
My practice has been that after 2-3 years of denosumab, I wait 6 months and then start zoledronic acid.
How do you think about using Ropeginterferon Alfa 2B for polycythemia vera in patients with active autoimmune disease?
Great question. In general, I avoid interferons in patients who have an autoimmune disease. In the PROUD-PV/CONTI-PV study, a medical history of autoimmune disease was an exclusion criterion. There have been reported cases of interferon-induced autoimmune disease, most commonly autoimmune thyroiditi...
Do you have to extend treatment for acute Lyme disease if a patient is on high dose steroids for another indication?
I am unaware of any evidence to support longer-term therapy in such a setting. I am quite sure no such study has ever been done. Standard therapy for early Lyme disease is 10 days of appropriate antibiotics. Extending to 20 days would likely do no harm to the patient, but may not be necessary, and t...
How do you approach PJP prophylaxis in patients with rheumatic disease on corticosteroids?
Here is a graphic I made covering PJP Prophylaxis with Dr. @Dr. First Last if anyone is interested! As noted, one can check absolute lymphocyte count (ALC) or CD4 count as factors to further risk stratify as well.
When evaluating a patient with IgG4-related disease, are there particular exposures or risk factors you routinely ask about during the history to help identify potential contributors?
While there are no well-established environmental or occupational risk factors but taking a thoughtful exposure history can provide valuable information about the phenotype of the disease and help exclude mimics. I routinely ask about the history of allergic or atopic conditions such as asthma, alle...
