In patients with connective tissue disease-associated interstitial lung disease (CTD-ILD) who have achieved clinical and physiologic stability after successful discontinuation of prednisone while on mycophenolate mofetil, how do you typically approach tapering or discontinuing the mycophenolate?
Unfortunately, there are no high-quality, evidence-based guidelines that specifically address tapering or discontinuing mycophenolate mofetil (MMF) in CTD-ILD after achieving clinical stability. The available literature strongly favors prolonged maintenance therapy rather than early discontinuation,...
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 ...
Where in the sequence of biologics would you consider guselkumab for patients with active psoriatic arthritis despite standard DMARD therapy?
This is an extremely important question and one that is likely to change as new data becomes available. It is important to remember that psoriatic arthritis (PsA) is a complex and heterogeneous disease and a single approach does not work for every patient. Based on the ACR/NPF 2019 PsA treatment gui...
How do you interpret treatment response in the DISCOVER-2 Trial when patients were allowed to remain on up to 10mg of prednisone equivalent for disease control while on guselkumab?
If patients were on less than or equal to prednisone 10 mg, they could continue that in the background during the trial, but note that only 20% of patients were on prednisone, a much lower figure than a typical rheumatoid arthritis trial, which is consistent with the point that rheumatologists shy a...
What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
With the increasing availability of biosimilars and their adoption onto payer formularies, how do you approach selection among available biosimilars in clinical practice?
Insurance payers consider FDA‑approved biosimilars to be clinically equivalent. In my experience, selection is ultimately driven by the insurance payer formulary - what you can get for the patient on the time. This can be fleeting and quickly changing at times. Cases can be made for patient experien...
In a patient with recurrent episodes of GCA that flare shortly after steroid tapering, how do you differentiate between steroid-dependent inflammatory relapse, an alternative autoimmune vasculitic process, and a paraneoplastic phenomenon?
Paraneoplastic disease rarely behaves like GCA with ischemic manifestations. If a non-GCA vasculitis is suspected, perhaps repeat biopsy or serologic testing for other markers could be done. I'm not sure of the value of these tests, however, given that the treatment approach with immunosuppression w...
How would you manage resuming successful abatacept therapy in a refractory RA patient undergoing resection of stage 1 lung adenocarcinoma?
You can restart the abatacept once the patient has recovered from surgery. There is no signal for increased new solid tumors on abatacept, and you would expect the patient to be cured after resection of a stage 1 tumor.
Should the use of avacopan be limited to those patients at increased risk of steroid toxicity given the anticipated high cost of this medication?
Once Avacopan is available for clinical use in the treatment of patients with AAV, providers will need to carefully weigh risks and benefits of the medication while considering other factors including cost.The ADVOCATE trial used a novel glucocorticoid toxicity index that captures common GC-related ...
In light of promising results of hydroxychloroquine in COVID-19, should we consider using it prophylactically in cancer patients, especially if immunocompromised?
At this time, as there is no good evidence available, I would not recommend the use of hydroxycholoroquine prophylactically in cancer patients. It is unclear whether it would prevent contagion, probably not, and we still don't know if it will have any effect on the course of COVID-19. We expect ther...
