Is your approach to managing immune related adverse events altered at all in light of COVID-19?
First of all, I wish to thank @Dr. First Last from Johns Hopkins/Sibley for his advice addressing this critical topic.We are all witnessing a rapidly evolving crisis that none of us have been prepared for and it is the right thing to quickly consider as best as we can how the COVID-19 pandemic shoul...
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 long would you recommend that a patient continues guselkumab prior to deciding that the therapy is not effective?
Many trials have a placebo-controlled period of 12-24 weeks. Thereafter, all patients receive active treatment. Even if the original treatment allocation remains unknown to the patient and doctor, they know that from that moment on, everyone receives active treatment. This will have an influence on ...
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 ...
Do you always pursue biopsy confirmation before diagnosing IgA vasculitis?
Technically, yes (by definition), but practically, not necessarily: Biopsy for direct immunofluorescence (DIF) testing would be required to confirm the status of IgA in cutaneous vasculitis. However, the presence of lesional IgA correlates positively with the clinical presentation (e.g., Henoch Schö...
Where in the sequence of biologics would you consider guselkumab for patients with active psoriatic arthritis despite standard DMARD therapy?
This is an extremely important question and one that is likely to change as new data becomes available. It is important to remember that psoriatic arthritis (PsA) is a complex and heterogeneous disease and a single approach does not work for every patient. Based on the ACR/NPF 2019 PsA treatment gui...
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...
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 the treatment of osteoarthritis with low-dose radiation therapy is there data to support the claim that LDRT does not limit or preclude later orthopedic surgery?
At LDRT doses, the biological effects are anti-inflammatory and immunomodulatory rather than cytotoxic or fibrogenic, and there is no evidence of vascular injury, impaired cellular proliferation, or tissue destruction. Animal models and cellular studies provide robust evidence that LDRT at OA releva...
In patients with osteoporosis at high fracture risk, what factors most influence your decision to prescribe teriparatide versus abaloparatide?
Both abaloparatide and teriparatide are very effective anabolic agents to reduce vertebral and nonvertebral fracture risk in patients with osteoporosis (although clinical trials did not demonstrate reduction of hip fracture risk). The two agents are more similar than different and both induce an an...
