Should patients starting cyclophosphamide be screened routinely for latent tuberculosis (TB)?
Yes, I think patients starting Cyclophosphamide should be screened routinely for latent TB since CYC is a strong immunosuppressant and increases the risk of TB reactivation. The issue is that CYC is often being considered for life or organ-threatening situations, for which it may not be ideal to wai...
What is your approach to counseling patients on the safety and side-effect profile of a biosimilar compared to its reference biologic?
Relevant question as insurance companies may require a biosimilar over the reference biologic. According to the FDA, the spin-off (my term) must be "highly similar" to the original in both efficacy and safety. Approval is based on review of clinical trial data. As for my approach: until proven other...
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 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 ...
Do you taper glucocorticoids less aggressively when symptoms improve but serologies remain active in a patient with non-renal SLE?
Cautious tapering of glucocorticoids is a good idea in the setting of ongoing serologic activity. However, given there is clinical improvement in symptoms, one can go ahead and proceed with tapering steroids. It is important to recognize that a subset of patients with SLE may have persistent abnorma...
How do you manage worsening cutaneous dermatomyositis when muscle disease appears controlled?
The fact that the patient still has an active pruritic rash while tapering steroids suggests that the current regimen isn't fully controlling the disease, and it can affect quality of life. I would consider adjusting immunosuppression, either adding another agent or switching therapies. The specific...
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...
Should tuberculosis screening be performed before beginning methotrexate for treatment of rheumatoid arthritis?
While it is not recommended or required to screen for latent TB (LTBI) prior to starting methotrexate, for many patients this may serve as a good opportunity to screen for LTBI, as many patients will go on to require biologic therapy due to incomplete response to methotrexate. There are many limitat...
What is the clinical significance of elevated serum complement (C3 and/or C4) levels?
I have always considered elevated complement levels to be an acute phase reaction and an indication of inflammation, be it infection or cancer, similar to the ESR and CRP. Recent data have linked these elevated levels with obesity and metabolic syndrome. We have known for years that levels of C3 and...
Would you biopsy calcified lung nodules and or lymphadenopathy that have shown stability over a 2-year period, in a bid to rule out sarcoidosis?
No. Certainly not without a comprehensive occupational and other exposure history. Follow "the rules" for the assessment of any sarcoidosis suspect. Do a physical exam to look for extrapulmonary signs of sarcoidosis. Order an eye exam to assess for ocular sarcoidosis. Obtain baseline MTB testing and...
