In a patient with recurrent episodes of GCA that flare shortly after steroid tapering, how do you differentiate between steroid-dependent inflammatory relapse, an alternative autoimmune vasculitic process, and a paraneoplastic phenomenon?
Paraneoplastic disease rarely behaves like GCA with ischemic manifestations. If a non-GCA vasculitis is suspected, perhaps repeat biopsy or serologic testing for other markers could be done. I'm not sure of the value of these tests, however, given that the treatment approach with immunosuppression w...
What drives you to initiate a csDMARD early rather than relying on prolonged corticosteroids alone in a patient with ICI-induced inflammatory arthritis who has moderate disease activity with polyarticular involvement and tenosynovitis at the time of rheumatology referral?
My approach differs somewhat from the traditional paradigm of early csDMARD initiation. In patients with immune checkpoint inhibitor-induced inflammatory arthritis (ICI-IA), particularly those with moderate disease activity, polyarticular involvement, and tenosynovitis, my primary goal is to avoid p...
In patients with sarcoidosis and persistently elevated liver function tests, when do you consider initiating ursodeoxycholic acid (UDCA)?
In patients with systemic sarcoidosis with predominantly elevated alkaline phosphatase, I would be suspicious for liver involvement of their sarcoidosis. If treatment of the systemic sarcoidosis with immunosuppression (typically initiated by Pulmonology or Rheumatology) are ineffective for improving...
Do you have safety concerns when prescribing GLP-1 medications in patients on corticosteroids or immunosuppressive therapy?
I think we need to be particularly careful when co-prescribing with systemic corticosteroids because of the risk of sarcopenia. We know that rapid weight loss is accompanied not only by a loss of fat tissue but also of muscle. Corticosteroids can also have myotoxicity and cause muscle atrophy. I the...
In light of promising results of hydroxychloroquine in COVID-19, should we consider using it prophylactically in cancer patients, especially if immunocompromised?
At this time, as there is no good evidence available, I would not recommend the use of hydroxycholoroquine prophylactically in cancer patients. It is unclear whether it would prevent contagion, probably not, and we still don't know if it will have any effect on the course of COVID-19. We expect ther...
Do you offer low-dose radiation therapy for osteoarthritis of the spine?
DEGRO has published guidelines on this very topic, so I would respectfully disagree with a comment arguing a lack of data. Of course, if one is looking for level 1 data on irradiating benign diseases in general, there may be little to satisfy.That being said, there's no level 1 data espousing the be...
How would you approach the evaluation and management of a patient with rheumatoid arthritis receiving leflunomide who presents with progressive peripheral pulmonary cavitary nodules, with biopsy revealing necrotizing granulomatous inflammation?
Given the association between leflunomide and nodules with necrosis and giant cells (though quite rare), I would consider stopping leflunomide and moving to another agent. I would, of course, make sure that cultures are negative on those nodules, given it could be mycobacterial, fungal, or even GPA.
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...
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...
In what clinical situations would you favor IM methylprednisolone over a short oral prednisone taper for managing an RA flare?
I am not an RA expert; however, I am well-versed in the use of IM steroids for flares.After Dr. Petri's FLOAT study in SLE (Danowski et al., PMID 16395750), we have utilized IM steroids instead of daily PO prednisone as our "go-to" treatment of choice as much as we can over Medrol dose packs and QD ...
