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...
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 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?
The dependence on the use of systemic glucocorticoids may indeed be a good reason to change treatment. Especially in patients with psoriatic arthritis. So, if patients are unable to stop systemic glucocorticoids and there are still treatment options for the patient, this could be tried. It is diffic...
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...
How do you optimize retinopathy screening schedules for patients on hydroxychloroquine while also prioritizing cost-effectiveness?
I'll approach this from the cost-effectiveness standpoint as I agree with Drs. @Dr. First Last and @Dr. First Last on their excellent points.Patients with SLE have remarkably high costs when you add up copays, medications, imaging studies, travel, missing work, etc. Anything we can do to help reduce...
Would you give a trial of immunosuppression in a patient with previously diagnosed IPF who now comes to you with moderate titer ANA and history of discoid lupus but no other clear systemic features or lab abnormalities suggestive of SLE?
No, I would not automatically RX immunosuppressants in this clinical scenario, which has numerous facets to it that do need to be addressed: The treatment for progressive idiopathic pulmonary fibrosis (IPF) is an antifibrotic, not an immunosuppressant. I ALWAYS manage my SLE-pulmonary patients with ...
How do you approach the management of inflammatory arthritis in a patient with Sjogren’s disease who is unable to tolerate or take methotrexate, leflunomide, or hydroxychloroquine?
Would consider a B-cell targeted agent. Currently, rituximab which was included in the 2017 MSK and biologic guidelines (Carsons et al., PMID 27390247) for SjD inflammatory arthritis.Serum level of BAFF is elevated in SjD, so an anti-BAFF agent, like belimumab, could be considered.Have avoided use o...
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...
How soon after a fracture would it be safe to start anti-resorptive therapy?
This is an important question. There is no definitive answer, and there have been no clinical or preclinical studies that demonstrate delayed healing in the presence of bisphosphonates. Personally, I favor waiting a few weeks before we start. That also gives us time to do a proper metabolic workup. ...
