Does calcinosis appear differently in patients with dermatomyositis compared to systemic sclerosis?
Classically, calcinosis in dermatomyositis and scleroderma are different with dermatomyositis having more typical sheet-like calcinosis in the muscles whereas in scleroderma it is more typical on the fingers, extensor surfaces of the forearm, olecranon, knee, and shins. However, many sclerodermas al...
How does evidence of cerebral amyloid angiopathy/microbleeds affect choices for secondary stroke prevention in patients with a history of ischemic stroke and atrial fibrillation?
This is a discussion I have with the patient, mentioning that the positive predictive value of cortically based cerebral microhemorrhages is not absolute, especially when there is a small number of them and there are no other signs of small vessel disease (such as FLAIR changes or enlarged peri-vasc...
What is your approach to immunotherapy-related pancreatitis?
Depending on the severity of the ICI-associated pancreatitis, I will start patients on prednisone 0.5 mg/kg/day - 1 mg/kg/day. Once lipase levels decrease and approach normal levels, I will start tapering at generally around 10 mg weekly with a total taper time that is typically close to 6 weeks. If...
How do you approach the treatment of eosinophilic fasciitis refractory to glucocorticoids and methotrexate?
As rheumatologists, we are accustomed to managing people with rare diseases. Eosinophilic fasciitis (EF) ranks among the rarest of the rare, so it is understandable that there are no carefully designed trials assessing the efficacy of the various immune-modulating drugs. Clearly, corticosteroids are...
Are there any specific circumstances when you would consider the use of immunosuppression for DISH?
DISH and SpA are two separate pathological entities that share involvement of the axial skeleton and peripheral entheses. Both diseases cause bone proliferation in the spine and extraspinal entheseal sites, particularly in the later phases of the disease.DISH is characterized by calcification and os...
In which clinical scenarios is relying on the urine protein-to-creatinine ratio as a measure of proteinuria unreliable, and interpretations should be made looking at urine protein and urine creatinine separately?
I typically only use spot UPCRs because (1) they are easy to obtain and thus trend (2) they account for BSA indirectly because it accounts for Cr excretion. The best role of urine protein measurements is really just to trend if your therapy is effective or to screen for disease. When looking at urin...
What is the best way to approach elevated liver enzymes in patients treated with combination TKI and immunotherapy?
We rely on clinical judgment in this case as both TKIs and immunotherapies can cause elevation of liver enzymes. Currently, the recommendations in case the attribution of the hepatitis is questionable is to hold both drugs and to check the liver enzymes daily; if it improves, then it is likely due t...
Can you use other iron formulations if a patient develops Stevens-Johnson Syndrome with ferumoxytol?
I have never seen it in tens of thousands of doses so it is difficult to answer. If this is actually real, it must be due to CHO component and not Fe (that would be awful). I would use another formulation and premedicate with steroid and H2 blocker before. Do not use antihistamine.
Should assessing for a MTHFR mutation be part of the thrombophilia evaluation in a patient presenting with a thrombus?
MTHFR mutation testing is of very little utility, given that the functional readout of MTHFR dysfunction is homocystinuria. The intake of the treatment of homocystinuria is folate, which is ubiquitous in the US diet. Thus, homocysteine levels would be adequate for testing, if such testing is indicat...
What is your differential for a patient presenting with multiple digits affected by flexor tenosynovitis, dupuytren's, and no evidence of peripheral inflammatory arthritis?
Other than idiopathic Dupuytren's and recreational or occupational flexor tenosynovitis, I would look for underlying thyroid disorders that can induce trigger finger with some palmar fascia and tendon thickening, and also diabetic cheiroarthropathy. There are several musculoskeletal complications se...
