Do you manage a patient presenting with ICI-induced PMR-like syndrome using the same glucocorticoid dosing and tapering schedule you would apply to primary PMR, or do you treat it as a distinct entity requiring a lower steroid dose given evidence suggesting it tends to be milder?
Thank you for the excellent question. Since ICI-induced PMR-like syndrome is often milder than primary PMR, and because prolonged glucocorticoid exposure may attenuate the anti-tumor efficacy of ICIs, I generally aim to use the lowest effective steroid dose and taper more rapidly than I would for pr...
How should the results of the ADVOCATE trial be applied in AAV patients who receive rituximab induction and maintenance therapy?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:The data from ADVOCATE indicate that patients with granulomatosis with polyangiitis (GPA) or microscopic polyangiitis (MPA) treated with avacopan 30 mg twice daily and prednisone placebo were able to achieve remission w...
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...
Before re-challenging a patient with ICI after grade 1-2 pneumonitis, do you re-image to confirm resolution of pneumonitis?
Grade 1 pneumonitis is defined as confined to one lobe of the lung or <25% of the total lung parenchyma, while grade 2 pneumonitis is defined as involving more than one lobe of the lung or 25-50% of the lung parenchyma. Grade 1 pneumonitis is typically an incidental finding on CT in an asymptomatic ...
How do you try to encourage interested medical students and residents to consider a career in rheumatology?
I try to expose them to the practice of Rheumatology and the depth and breadth of what we do, not merely musculoskeletal medicine but every organ system. The beauty of the immune system when it works properly and the many ways we try to control it when it does not behave. The chronic care of these d...
Do you screen for interstitial lung disease in patients with newly diagnosed polymyositis or dermatomyositis in the absence of respiratory symptoms?
I do screen all newly diagnosed IIM patients with PFTs and chest CT. This has a double purpose: establishing a baseline of lung function and, screening for lung cancer. While the patient might not have lung symptoms on presentation, respiratory involvement can manifest later on the course of the d...
Are the results of the SEAM-RA trial generalizable to other TNF inhibitors given the differences in immunogenicity?
This is a great question, and an important one because different TNF inhibitors have different immunogenicity and patients can make anti-drug antibodies that can effectively neutralize the drug and render it a less effective treatment option. This tends to happen more with some molecular constructs ...
In patients with sarcoidosis and persistently elevated liver function tests, when do you consider initiating ursodeoxycholic acid (UDCA)?
In patients with systemic sarcoidosis with predominantly elevated alkaline phosphatase, I would be suspicious for liver involvement of their sarcoidosis. If treatment of the systemic sarcoidosis with immunosuppression (typically initiated by Pulmonology or Rheumatology) are ineffective for improving...
How do you approach tapering decisions for disease-modifying therapy for ICI-induced inflammatory arthritis after the patient's cancer treatment has been completed or the ICI has been discontinued?
This is a great question and, honestly, one that every rheumatologist struggles with. Similar to managing other inflammatory diseases, the challenge is determining when a patient is truly in remission and whether therapy can be safely reduced or discontinued.My approach is fairly practical: The pati...
Under what circumstances would you consider low-dose radiation therapy for osteoarthritis in an older adult patient?
Almost any and all circumstances.
