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 ...
Would the need for infliximab/MTX/nonsteroidals to control initial irAE affect your decision to rechallenge these patients with ICI?
Infliximab and methotrexate are generally used in irAE grades 3 or 4, or in grade 2 irAEs that are refractory to initial treatment with steroids. Methotrexate is typically used for irAEs of the musculoskeletal system, such as inflammatory arthritis or myositis. Infliximab tends to be used in the set...
How do you approach management of new onset ILD in a patient with RA who is otherwise well controlled on methotrexate or leflunomide?
We do not have any randomized controlled trials for DMARDs in RA-ILD. Most of the data is case series or retrospective analysis. Nonetheless, we can use current data to at least make clinical decisions until we receive more direction from high-quality clinical trials. We now know that in general met...
What is the recommended fungal workup in an immunocompromised patient after 5 days of persistent fever?
For any patient with fevers, I focus significantly on any symptoms that a patient might have, like headache, diarrhea, and sinus symptoms, and work up a differential diagnosis based on possible pathogens in this area. If I am not finding anything, I would obtain a CT chest/abd/pelvis, as both invasi...
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...
What is your approach to a patient with RF+/CCP+ rheumatoid arthritis that was previously on TNFi now with high-titer ANA and dsDNA (crithida 1:2560), +chromatin, +histone?
A key part of this question is "previously on TNFi." Anti-TNF-induced lupus (ATIL) usually resolves within 2-8 weeks after stopping the TNFi. This includes anti-dsDNA, which is usually at low to moderate titers when seen in ATIL, rather than the high-titer Crithidia dsDNA as is seen here.High positi...
What is your approach to management of a patient with sarcoidosis who is asymptomatic, but demonstrates progressively enlarging mediastinal lymphadenopathy and rising soluble IL-2 receptor levels?
My concern here would be whether such a patient does not have 'asymptomatic sarcoidosis' but has CVID (often associated with multifocal non-caseating granulomas) with an associated B-cell lymphoma (for which such patients have a 30-fold Relative Risk) with developing mHLH (elevated sIL-2 being an as...
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 ...
Which biologics for severe RA are safe in CKD4?
TNF blockers are usually safe in patients with CKD due to less renal toxicity.
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 ...
