What is the most appropriate next step in management for a patient with dermatomyositis who is maintained on methotrexate 25 mg weekly but develops disease flare when prednisone is tapered below 10 mg daily and is unable to receive IVIG?
The fact that the patient cannot taper prednisone below 10 mg indicates that methotrexate alone, while has some effect, is not sufficient to control the disease. There are several options, depending on the severity of each organ involvement. Since the joints are affected, I would favor an agent that...
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...
How will you incorporate nerandomilast into your treatment algorithm for autoimmune ILD with progression, particularly relative to sequencing with immunosuppression?
The sequencing of therapy in CTD-related PPF remains unclear. Recent data suggest that immunosuppression may not alter clinical outcomes in fibrotic ILDs, including those associated with systemic autoimmune disorders (Pugashetti et al., PMID 42432856). In the FIBRONEER-ILD study, nerandomilast impro...
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...
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...
