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...
Do you recommend checking anti-drug antibodies for patients on TNF inhibitors?
This is a very good question with direct clinical practice implications. I do not check or follow anti-drug antibodies when using TNF inhibitors for the treatment of rheumatoid arthritis or psoriatic arthritis. There are reports that suggest, on a group level, that these antibodies, if present, impa...
How do you approach management of rheumatoid vasculitis (in this era)?
We don't see rheumatoid vasculitis very often nowadays. When our drug options for RA were limited, most patients had smoldering ongoing disease, which predisposed them to the possible development of a rheumatoid arthritis related vasculitis, though even then, cases were uncommon. Nowadays, our abili...
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 ...
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 recommend allopurinol desensitization in gout patients who develop a rash on allopurinol therapy?
I don't recommend desensitization for allopurinol-allergic patients. There was a time when this made sense due to the lack of a viable alternative therapy. The process is cumbersome in a private practice setting and not as simple as providing the patient with a prescription for febuxostat.Febuxostat...
Is it still significant to denote the etiology of ILD in a patient with PPF?
Yes, absolutely! Infact, the most effective treatment in patients without IPF (PPF) is treatment of the cause. So if there is underlying autoimmune disease or exposure, primary treatment should be directed against that trigger and this has potential to stop progression and even improve lung function...
In a patient with known APS (triple positive) and interstitial lung disease (NSIP), how do you distinguish APS associated lung involvement from connective tissue disease related ILD?
Patients with APS typically have vascular and thrombotic pulmonary disease, and very rarely has interstitial disease been ascribed to APS. The most common pulmonary manifestation of APS is pulmonary embolism, occurring in 14-16% of patients, followed by pulmonary hypertension often caused by chronic...
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 ...
