Do you cycle through topical steroids in patients with CHE, and should the approval of delgocitinib change our approach on this?
In practice, I do often cycle topical steroids in chronic hand eczema to balance access, efficacy, and safety. Patients are often referred from primary care already having tried multiple topical steroids. Potent topical steroids can help with acute control, but long-term use is problematic. The avai...
For a patient with ICI toxicity who is resistant to the use of high-dose steroids, are there scenarios where you would consider the use of first-line conventional synthetic DMARD in place of steroids?
Loaded question — I think we need a reframing of ICI-toxicity, much of the ICI side effects are just an autoimmune reaction in a specific organ. High doses of steroids are used if there is a true risk for organ damage (like when you have acute ANCA vasculitis, lupus nephritis, etc.). So if a patient...
Are there certain clinical features that help you choose between benralizumab and mepolizumab for EGPA in clinical practice?
Given, as noted above, no significant clinical differences between benralizumab and mepolizumab, assuming there are no specific insurance differences between the two, I preferentially prescribe benralizumab because of the 8-week dosing frequency after the first three 4-week loading doses. For a few ...
In patients with SLE and coexisting knee osteoarthritis, how useful is musculoskeletal ultrasound particularly power Doppler in distinguishing an SLE inflammatory arthritis flare from an OA flare when serologies and inflammatory markers may not be helpful?
Unfortunately you are correct. Ultrasound alone is not able to distinguish between an effusion or synovitis due to the patient's OA or SLE. You would have to assess clinically for other evidence of an SLE exacerbation, and/or aspirate and analyze the fluid (which may be easier using ultrasound guida...
What would be the minimum duration of IL-1 therapy you would recommend for chronic pericarditis?
There is no great data. In my experience, it depends on the reason for IL-1 initiation, the severity of cMRI findings, and how chronic the pericarditis was prior to initiation.. If this is used as a steroid-sparing strategy or steroid weaning, probably 1-2 years minimum. In Rhapsody, the majority fl...
Would you biopsy calcified lung nodules and or lymphadenopathy that have shown stability over a 2-year period, in a bid to rule out sarcoidosis?
No. Certainly not without a comprehensive occupational and other exposure history. Follow "the rules" for the assessment of any sarcoidosis suspect. Do a physical exam to look for extrapulmonary signs of sarcoidosis. Order an eye exam to assess for ocular sarcoidosis. Obtain baseline MTB testing and...
What is your approach to treating IgA nephropathy in patients who also have IgA vasculitis?
In a patient with known IgA Vasculitis [IgAV], IgA dominant pattern of injury in the kidney biopsy reflects IgA Vasculitis with Nephritis [IgAV-N]. Thus, it would not be appropriate to call it IgA nephropathy [IgAN] in IgAV. Though the histological features in IgAN and IgAV-N can be common in the ki...
When do you obtain nerve biopsy to evaluate for vasculitic neuropathy in patients with distal symmetric polyneuropathies?
Excellent question. Vasculitic neuropathies can occur as part of systemic or isolated peripheral nerve vasculitis (PNSV). While the majority of PNSV presents as mononeuropathy multiplex (>50%), it is well known that the rest of the patients present either with confluent mononeuropathies (which began...
Have you utilized denosumab in treatment of erosive hand osteoarthritis?
I have not prescribed denosumab for patients with erosive hand osteoarthritis. While the 2024 double-blind placebo-controlled trial suggested that this RANK ligand inhibitor may have structure-modifying effects by inducing remodeling and preventing new erosions, the phase 2a study of 100 patients di...
How would you approach management of retroperitoneal fibrosis causing ureteral compression that has already caused irreversible loss of kidney function?
I agree with my colleagues and will add some additional thoughts. While I agree that tissue diagnosis is helpful whenever it can be obtained (both to differentiate IgG4-related vs idiopathic RPF and to exclude other causes such as lymphoma, sarcoma, and Erdheim-Chester Disease), it is often the case...
