Do GLP-1 agonists have measurable anti-inflammatory effects in diseases like RA or spondyloarthropathies beyond weight loss?
There is currently no evidence of efficacy in chronic inflammatory arthritis. Due to their mechanism of action, we can hope that they will be effective because of their anti-inflammatory and immunomodulatory properties, which have been well demonstrated in numerous experimental models. But only rand...
Would you start hydroxychloroquine (or another DMARD) in a mid-20s female patient with positive ANA, SSA, SSB, and dsDNA, whose only clinical manifestation is intermittent parotid gland swelling?
Hmm... I think the better question to ask is, do you code as Sjogren's lupus overlap to get way more medication options? Certainly, HCQ is a reasonable DMARD and a place to start for both diseases. I would code as lupus and Sjogren's to have more options for the future. Hope someone can weigh in on ...
How do you approach adding colchicine to a patient who is on a stable statin regimen?
This is a good question and a tough situation, since the drug-drug interaction here can be as subtle as myalgias but as severe as rhabdomyolysis (rare but happens). If you can avoid long-term colchicine in this situation, it is always best. These situations (hypercholesterolemia and crystal arthropa...
Do you routinely transition to PO antibiotics for patients with native joint septic arthritis whom have undergone washout and the organism is not S. aureus?
Yes. Even if the organism is Staph aureus, I would feel comfortable with an appropriate, highly bioavailable oral antibiotics after appropriate source control (linezolid in the case of Staph aureus).
Would you offer re-irradiation LDRT for someone with osteoarthritis or tendinitis if symptoms recur?
I have not personally offered a patient a third round of LDRT and do not know of any data that shows efficacy. However, I might offer a third round if a particular patient got adequate results with the first two and there was some separation in time (perhaps >1 year) since the last round.
In a patient with known APS (triple positive) and interstitial lung disease (NSIP), how do you distinguish APS associated lung involvement from connective tissue disease related ILD?
Patients with APS typically have vascular and thrombotic pulmonary disease, and very rarely has interstitial disease been ascribed to APS. The most common pulmonary manifestation of APS is pulmonary embolism, occurring in 14-16% of patients, followed by pulmonary hypertension often caused by chronic...
How often are you performing CT screening in CVID patients to screen for ILD?
CT once every 1-2 years, depending on symptoms and PFTs. PFTs, including DLCO, are annually performed.
What is your approach to differentiating between drug induced lupus versus elderly onset SLE?
Close to 50% of SLE patients are anti-histone positive. In a scenario like this, it is not helpful. This is SLE until proven otherwise. Regarding elderly onset SLE vs drug-induced lupus, I evaluate and distinguish them similarly to how I do in younger patients.
How do you work up patients who present with elevated myoglobin in the setting of normal creatinine kinase and exercise intolerance?
Myoglobin may originate either from cardiac or skeletal muscle; therefore, I would first try pinpointing the origin with troponins and CK fractions. I would work up the exercise intolerance with a non-ischemic forearm test to determine whether a flat lactate curve is present. In that case, I’d typic...
How do you approach incidental NXP-2 antibody positivity in patients without current clinical evidence of myositis or systemic autoimmune disease?
A positive anti-NXP2 antibody in an asymptomatic patient may indicate either a false positive or a subclinical form of dermatomyositis. The initial step is to review the testing method (e.g., ELISA, immunoblot). If possible, confirm the result with a different assay, ideally immunoprecipitation, tho...
