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 you consider combination mycophenolate and JAKi in a patient with RA-ILD?
I have minimal experience combining a JAKi with mycophenolate. A patient with RA-ILD whose joints were well controlled with tofacitinib but whose ILD was progressing had MMF added to their regimen by their ILD pulmonologist. Unfortunately, after 4 months, the patient developed significant leukopenia...
What is in the differential diagnoses for isolated bilateral tarsometatarsal joint erosions in the absence of other clinical or serologic evidence of systemic inflammatory arthritis?
Post-traumatic injury is the most common cause, especially mid-foot sprains and fractures, although not usually bilateral unless there is a predisposition such as high arches and osteoarthritis (OA) that can occur due to mechanical stress. Erosive OA can cause these findings, although more commonly ...
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 patients with a history of retinal vein occlusion, how should the risk of recurrent thromboembolic events influence the selection of osteoporosis therapies?
The FDA-approved prescribing information for raloxifene explicitly lists retinal vein thrombosis alongside deep vein thrombosis and pulmonary embolism as contraindications.
How often are you repeating screening PFTs in patients with SARDs who have 3 or more years of normal or stable PFTs?
The answer to this question is complex and needs to be tailored to the individual patient’s risk for ILD and the particular SARD.Approximately 30-40% of patients with systemic sclerosis (SSc) will develop ILD, typically within the first 5 years after the first non-Raynaud’s manifestation and rarely ...
What is your approach to escalating therapies for stiff person syndrome that is refractory to IVIG and steroids?
Step 1: Make sure the diagnosis is correct, especially if seronegative or very weakly positive for GAD65 antibodies.Misdiagnosis of SPS is common and diagnostic criteria have been recently proposed (Reference 1). Patients who complain of subjective stiffness/muscle spasms, but do not have objective ...
Is there a period of time after which you would not resume ICI after a patient has had an irAE and required a prolonged steroid taper?
Typically if a patient has required treatment with steroids for four to six months, it was because their irAE was significant (grade 2-4) and refractory to initial treatment. If the patient received combination immunotherapy, such as anti-CTLA-4 and anti-PD-1 agents, one could consider resuming the ...
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 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...
