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 ...
Has the MAJESTY trial changed your approach to the rituximab versus obinutuzumab choice in a patient with newly diagnosed primary membranous nephropathy and nephrotic syndrome?
The Bottom Line: Recent landmark trials—MENTOR and MAJESTY—confirm that anti-CD20 therapies are superior to calcineurin inhibitors (CNIs) for the treatment of MN.Key Trial DataMENTOR: Demonstrated that RTX was noninferior to cyclosporine at 12 months, and decisively superior by 24 months (60% vs. 20...
Are there particular subsets of AAV patients in which avacopan is more effective?
The following answer was jointly drafted by Dr. Peter Merkel and Dr. David Jayne:Patients in the ADVOCATE trial were stratified at entry according to time of diagnosis (new/relapsing), diagnosis (GPA/MPA), ANCA serotype (PR3/MPO), and background immunosuppressive (cyclophosphamide/rituximab) with re...
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...
What specific criteria or patient conditions would make you hesitant to use fluoroquinolones early in the treatment course for managing MSSA joint infections with oral antibiotics?
For MSSA joint infections, I have moved away from using FQ to using high-dose cephalosporins as a step-down therapy, particularly cefadroxil 1 g twice daily, given less frequent dosing/increased adherence. Considering the risk-benefit analysis, I prefer using FQ as an oral option in polymicrobial an...
Will you give a trial of tirzepatide in patients with PsA and obesity who have a partial response to bDMARD rather than switching their immunosuppressive regimen?
I don't believe the data on the magnitude of the benefit of GLP-1 agonists in arthritis symptoms is sufficient to suggest that adding one of these agents would be preferable to changing DMARDs in a patient with inadequate response.
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...
Do you have safety concerns when prescribing GLP-1 medications in patients on corticosteroids or immunosuppressive therapy?
I think we need to be particularly careful when co-prescribing with systemic corticosteroids because of the risk of sarcopenia. We know that rapid weight loss is accompanied not only by a loss of fat tissue but also of muscle. Corticosteroids can also have myotoxicity and cause muscle atrophy. I the...
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...
Is there a role for nitazoxanide for treatment of norovirus gastroenteritis in immunocompromised patients?
There is no good-quality evidence supporting a role for nitazoxanide for treatment of norovirus gastroenteritis in immunocompromised patients. The efficacy of nitazoxanide in viral gastroenteritis is supported by a small manufacturer-sponsored randomized, double-blind trial in non-immunocompromised ...
