Are you comfortable with using NSAIDs in a patient on methotrexate for inflammatory arthritis?
Yes, there is a theoretical drug-drug interaction here. However, I don’t avoid using the combination altogether. In certain patients, I am still using NSAIDs in combination with MTX. However, not uncommonly, the patient’s pharmacist may warn the patient of this potential interaction, and they would ...
Do you continue TNF inhibitors in patients with a new diagnosis of CLL?
If the patient does not require any treatments for CLL that are potentially immunosuppressive, I would continue TNF-inhibitor therapy in this setting. It is always helpful to discuss the case with the patient's hematologist/oncologist to make sure everyone is comfortable with the plan.
How do you approach peri-operative management of anti-resorptive therapies such as denosumab in patients undergoing joint replacement?
This is a very practical question. I think it is fine to continue the denosumab on a regular 6-month schedule for patients undergoing joint replacement. The reduction in bone turnover should not affect the implant. In fact, with denosumab, there is a small anabolic effect with each treatment that mi...
How do you approach recurrent migratory superficial thrombophlebitis in a patient with a negative malignancy workup and low-titer anticardiolipin antibodies?
With anticoagulation using a DOAC.
How do you approach a patient with Paget’s disease of bone with elevated alkaline phosphatase and history of chronic kidney disease?
You can give Zol IV, which is clearly the optimal treatment for active Paget's. Those in the field that treat many such patients just administer this very slowly over 1-2 hours and assure good hydration concomitantly. I have treated a number of patients like this, with this scenario, without any pro...
How do you counsel and manage joint pain after isotretinoin treatment?
Firstly, if one starts with 0.5mg/kg joint symptoms rarely happen. My approach is to temporarily stop isotretinoin until symptoms pass and then start at half the previous dose and treat until clear. The ineffective dose was never found. We know now the critical factor in relapse is age-no matter wha...
Would you switch azathioprine to a different immunosuppressant if a controlled patient with SLE develops melanoma and/or non-melanoma skin cancer?
This is a difficult question with no definitive research-proven answer. Clearly, most of our drugs do enhance the chance of melanoma and nonmelanoma skin cancer. If one does a literature search the only one of our drugs that has not been reported to increase the chance for relapse of melanoma is Tac...
How would you approach evaluation and treatment of a patient on pembrolizumab therapy who presents with symmetric, proximal, upper extremity and lower extremity painful weakness without an elevated CK?
Pembrolizumab, like other checkpoint inhibitors, is associated with a number of immune mediated neuromuscular syndromes including GBS/CIDP, a myasthenic syndrome, and myositis. A patient with symmetric proximal weakness and normal CK could have any of the above conditions. Normal CK does not exclude...
How would you treat suspected secondary HLH in patients whom etoposide is contraindicated?
Thank you for the interesting question. It would be helpful to understand why etoposide is contraindicated. My general approach for these patients is to first ensure that there is no evidence of malignancy as a trigger as you do not want to mask that with steroids (I strongly recommend obtaining a P...
How do you manage calcium and vitamin D supplementation in patients with sarcoidosis on chronic steroids?
This is a great question with very limited data to help answer it well. The first-line therapy for sarcoidosis is corticosteroids, and chronic use can lead to decreased bone mass. Of course, Vitamin D supplementation is a very important factor in rebuilding bone mass. In sarcoid patients, this issue...
