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 ...
How do you manage patients with severe hand OA (no synovitis on exam, negative serologies) who fail to respond to NSAIDs but respond very well to oral steroids?
I have used Hydroxychloroquine with some success and offer that to patients for a trial for 4 months if they are willing.
Do you recommend medical therapy for extensive atraumatic osteonecrosis of the femoral head to mitigate pain or prevent femoral head collapse?
This is a good question. Extensive atraumatic ON of the femoral head will probably not respond to any medical therapy; eventually, the patient will need a replacement. However, ON that is from a systemic insult (drugs, alcohol) is often bilateral so if the other hip is less affected or not affected,...
What additional workup and steroid-sparing option would you choose in a patient with potential medium-vessel vasculitis (petechial rash, sensorimotor neuropathy, renal infarcts, renal artery micro-aneurysms and ischemic/ulcerative duodenitis), hypocomplementemia, ASO 1525, negative blood cultures and normal echo?
This is a challenging case. Generally, PAN should be confirmed histologically, particularly if there are atypical features. In this case, hypocomplementemia is atypical, as non-HBV-associated PAN is generally normocomplementemic. Further, PAN more commonly causes ulcers/nodules/reticular lesions tha...
When should patients with diabetes mellitus be screened for osteoporosis?
Hip fracture risk is higher in patients with diabetes (T1DM almost 7 times and T2DM 38% higher than controls without diabetes) (Vestergaard, PMID 17068657), and BMD scores underestimate true risk. That has led the ADA to suggest considering treatment for bone densities with T-score <-2.0, rather tha...
How do you approach osteoporosis screening in men?
While osteoporosis is more prevalent in postmenopausal women, it is often under-recognized in men. The risk of mortality after hip fracture is higher in men, and that risk may extend over 10 years after injury. Men who sustain a wrist fracture are more likely to have severe osteoporosis and a higher...
Do you recommend patients hold folic acid on the day they take methotrexate?
The proposed mechanism of action (MOA) of methotrexate in rheumatic disease is not from the antimetabolite angle (given its oncologic MOA as a dihydrofolic acid reductase inhibitor), but rather as a potent anti-inflammatory and immunomodulatory medication through the MOA of extracellular adenosine a...
Is your approach to managing immune related adverse events altered at all in light of COVID-19?
First of all, I wish to thank @Dr. First Last from Johns Hopkins/Sibley for his advice addressing this critical topic.We are all witnessing a rapidly evolving crisis that none of us have been prepared for and it is the right thing to quickly consider as best as we can how the COVID-19 pandemic shoul...
How do you manage patients with scleroderma who present with finger ulcerations without other signs of soft tissue infection and MRI demonstrates potential concern for osteomyelitis?
I think this is a tricky situation. Sometimes there is bone damage from acro-osteolysis from the ischemic injury of the scleroderma itself, which can sometimes be difficult to distinguish from osteomyelitis. I would consider watching closely for other signs of deeper infection. You could also consid...
Was the methotrexate dose reduced over time in the combination therapy or methotrexate monotherapy groups in the SEAM-RA trial?
No, methotrexate dose was not adjusted. Our goal was basically to answer one question: whether it is better to stop etanercept, stop methotrexate, or continue both. We did not want to be adjusting methotrexate doses at the same time as stopping because this would make results more difficult to inter...
