When, if ever, would you consider methotrexate over prednisone for first line therapy in patients with pulmonary sarcoidosis?
The PREDMETH trial supports the use of methotrexate for initial therapy for sarcoidosis. Future studies may identify subgroups that may benefit from the concurrent use of prednisone initially; it is unclear how soon methotrexate may provide symptomatic relief compared to the ability of an appropriat...
How do you decide when to discontinue immunotherapy for primary angiitis of the central nervous system (PACNS)?
I take a multidisciplinary approach with involvement of my neurobiology and rheumatology colleagues for the immunotherapy. PACNS can be relapsing or remitting. So needs close monitoring with radiologic (MRI and MRA high resolution vessel wall imaging or CTA/MRA with CSF studies 6 months and then 1 y...
Would you consider using avacopan in PR3+ mononeuritis multiplex without other systemic involvement?
I would certainly consider using avacopan in AAV mononeuritis multiplex. While we don't know the outcomes of mononeuritis in avacopan-treated patients specifically, ~20% of patients in the ADVOCATE trial (Jayne et al., PMID 33596356) had neuropathy and the outcomes overall suggest a robust response ...
Do you generally pursue a temporal artery biopsy in a patient who has a halo sign on ultrasound but has an atypical clinical presentation of GCA with normal inflammatory markers in the setting of persistent temporal headache?
This is an important question, and the answer would depend significantly on the details of the presentation. In general, with a highly atypical presentation such as this with normal inflammatory markers AND atypical symptoms, I would pursue TA biopsy and consider large vessel imaging if negative. Wh...
Does receiving IVIG confound the result of SPEP and/or UPEP?
IVIG being a product of polyclonal immunoglobulins may ‘produce’ a monoclonal spike if the AUC is falsely calculated by the reader. IFE usually shows polyclonal banding but every now and then a monoclonal band is picked up. Being an IgG molecule with a 21 day halflife; and with the assumption that i...
What is your treatment algorithm for management of retroperitoneal fibrosis that does not respond to high-dose glucocorticoids?
There are a number of caveats to this. Is the retroperitoneal fibrosis biopsy-proven and/or IgG4 disease ruled out? If a case is refractory, I first question whether the diagnosis is correct and will often biopsy in this situation with more than an FNA biopsy. The second question is how long have t...
Would you use the pneumococcal conjugate-21 vaccine (Capvaxive) instead of the conjugate-20 (Prevnar-20) for routine vaccinations in immunosuppressed patients?
PCV-21 was recently approved by the FDA and supported by ACIP. At this early stage (August 2024), CDC has not finalized guidance on PCV-21, so we do not know how the vaccine schedule will be changed. An important distinction is that PCV-21 covers different serotypes of pneumococcus, as outlined in t...
How do you counsel patients with depression about the role exercise may play in alleviating depressive symptoms?
I’m a big fan of exercise for all of my patients, to the point where I have my 5th-degree black belt diploma on the wall of my office next to my undergrad, PhD, and MD diplomas. I tell patients, “That’s up there to say to try and fit in exercise as realistically as your schedule allows, in a way you...
What are your vaccine recommendations while patients are on biologics?
Live vaccines are best completed at least a month before initiation of biologics when these are appropriate (e.g., MMR, chickenpox, yellow fever). The data on non-live vaccines is limited. I personally think that some degree of protection is better than none. I will not interrupt biological therapy ...
How do you approach selecting optimal muscle biopsy site when evaluating a patient for suspected inflammatory myopathy?
There are a few things to consider when formulating your approach to this, which include 1) the clinical exam, 2) ease of biopsy of muscle, and 3) potential confounders of diagnosis. The goal is to get a specimen from a muscle that is undergoing active inflammation. These muscles will generally be w...
