Under what circumstances would you consider low-dose radiation therapy for osteoarthritis in an older adult patient?
Almost any and all circumstances.
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...
Do you check for JCV before starting belimumab?
No. The John Cunningham virus (JCV) is highly prevalent in adults (around 85% of us), and developing progressive multifocal leukoencephalopathy (PML) is incredibly rare in belimumab (BEL) patients. It would not change my patient management. Even if someone tested negative for JCV prior to starting ...
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 ...
For patients <65 with significant intermittent steroid exposure who otherwise do not have risk factors for osteoporosis, when, if ever, do you recommend considering DEXA screening?
The FRAX guidelines recommend answering "Yes" for glucocorticoid use when a patient has received the equivalent of prednisone ≥5 mg daily for more than 3 months. However, many patients with rheumatoid arthritis have been treated with intermittent courses of corticosteroids over several years, which ...
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...
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 ...
In patients with SLE do you have concerns about using trimethoprim-sulfamethoxazole (Bactrim) because of a potential risk of lupus flare?
I agree with Dr. @Dr. First Last . I have had too many SLE patients over the years show up in my office with a severe flare from TMP/SMX. We have too many alternative antibiotics these days, including for PJP prophylaxis, so sulfonamide antibiotics should be avoided in SLE patients. The typical scen...
Do you screen for cardiac disease in patients with dermatomyositis in the absence of symptoms?
I don't typically evaluate for cardiac disease in patients with dermatomyositis who are not symptomatic. There are subtypes of myositis patients where cardiac involvement is more common (such as those with antimitochondrial antibodies and anti-SRP antibodies), and there it may make sense to keep a c...
Can needle EMG or nerve conduction studies cause transient MRI abnormalities, such as apparent inflammation, edema, or enhancement of a nerve, that could be mistaken for neuritis on subsequent imaging?
Yes—needle EMG can create small, transient post-procedure MRI/MR-neurography abnormalities at needle insertion sites, including focal T2/STIR hyperintensity interpreted as edema and occasional small hematoma, which can potentially be mistaken for local pathology if the timing is not recognized. In a...
