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 ...
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 ...
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...
In the setting of new onset severe Raynaud’s with digital ischemia (partial toe amputation), but negative initial rheumatologic evaluation, what additional rheumatologic or hematologic workup should be considered?
This is always a difficult situation. As Rheumatologists, we tend to lean hard on the laboratories, but in cases like this, it is the history and physical examination that tell the better story. The history is critical here, since a smoking/tobacco history gives a lot of information. Any history of ...
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 ...
Would you use febuxostat for an African-American patient with gout and previous cardiovascular events (stroke, MI) who tested positive for HLA-B*5801?
Well, I would certainly avoid using allopurinol. The initial CARES trial raised concerns about the safety of febuxostat, using a median dose of 40 mg. The subsequent study FAST did not show any signals of CV disease using a median dose of 80 mg. The internal validity of the study was greater in the ...
Do you always perform salivary gland biopsy to confirm the diagnosis In patients with suspected seronegative Sjogren's syndrome?
I often struggle with the decision of obtaining a biopsy in suspected Sjogren's in a person who is seronegative, when the main issue is dryness, and the main reason is that I wonder if it will make a difference in management. When I was a Rheumatology fellow, I was taught to give Hydroxychloroquine ...
How would you approach management of retroperitoneal fibrosis causing ureteral compression that has already caused irreversible loss of kidney function?
I agree with my colleagues and will add some additional thoughts. While I agree that tissue diagnosis is helpful whenever it can be obtained (both to differentiate IgG4-related vs idiopathic RPF and to exclude other causes such as lymphoma, sarcoma, and Erdheim-Chester Disease), it is often the case...
Is it safe to continue azathioprine in a patient with severe bilateral panuveitis (thought to be related to sarcoidosis) and benign ethnic neutropenia, given worsening neutropenia since starting the medication, or should an alternative immunosuppressive agent be considered?
In this case, I would consider stopping azathioprine and switching to an alternative medication, such as an anti-TNF agent. Although not a large drop in the PMN, azathioprine is known to cause leukopenia, and in a patient with known neutropenia, extra precaution should be taken. In the case of uveit...
