In a patient with longstanding Sjogren’s disease (+SSA/SSB and RF with polyclonal hypergammaglobulinemia) who develops new asymmetric parotid fullness what is your preferred initial imaging modality to further evaluate?
I would usually start with ultrasound in this case, specifically looking for signs of lymphoma, and let the results guide any further workup necessary. I have often seen benign parotid swelling in these patients, but an asymmetric presentation such as this requires further workup and potentially bio...
In patients with severe osteoporosis, history of retinal artery occlusion, and hypercalciuria, would you favor PTH analogue therapy or Evenity?
Assuming that PTH and vitamin D are normal, neither. Chlorthalidone is the treatment of choice in this scenario. Chlorthalidone is usually better than HCTZ, as HCTZ often must be given BID, whereas chlorthalidone can be given daily. I have seen very large improvements in BMD with thiazide therapy, o...
What therapies do you offer patients who have osteoporosis and CKD and have had adverse reactions to several oral bisphosphonate therapies and denosumab?
Without further details as to the severity of CKD, the severity of the osteoporosis, and the specific intolerance issues with denosumab (and/or BPs), this is a very difficult question to provide specific advice. Some general comments can be offered: CKD stage 4-5 is essentially without fracture data...
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...
How would you approach treatment for a patient with positive C- ANCA/PR3 with sinus/nasal limited disease, but no renal or pulmonary involvement?
The treatment of non-severe GPA varies amongst practitioners because of limited trial data and different practice patterns. 2021 ACR/VF guidelines conditionally recommend methotrexate and glucocorticoids. Rituximab would also be a reasonable option, therefore I typically favor shared decision-making...
Under what circumstances would you consider low-dose radiation therapy for osteoarthritis in an older adult patient?
Here is a recent expert consensus by Joel Block on the use of low-dose radiation therapy in OA: Some highlights: "Placebo-controlled randomized clinical trials have now been reported using LDRT for OA of the knees and of the hands. Taken together, they do not show benefit beyond placebo... While a d...
What is your approach to the diagnostic workup of small fiber neuropathy in patients with known rheumatic disease?
Small fiber sensory neuropathy (SFN), in general, including in patients with rheumatic diseases, should be suspected based on symptoms (positive more than negative sensory symptoms) and ideally confirmed by clinical examination showing altered temperature and/or pain/pinprick perception in the limbs...
In the treatment of osteoarthritis with low-dose radiation therapy is there data to support the claim that LDRT does not limit or preclude later orthopedic surgery?
At LDRT doses, the biological effects are anti-inflammatory and immunomodulatory rather than cytotoxic or fibrogenic, and there is no evidence of vascular injury, impaired cellular proliferation, or tissue destruction. Animal models and cellular studies provide robust evidence that LDRT at OA releva...
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...
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.
