What serologic biomarkers do you send to assess for sarcoidosis at baseline and/or during flares, in patients where it may correlate with disease activity?
Elevated ACE, dihydroxy vitamin D, and soluble IL2r levels have been shown to correlate with disease activity, but it is important to keep in mind that the sensitivity and specificity are variable and they should never be used in isolation to diagnosis or assess disease activity in sarcoidosis. The ...
How do you approach a patient with sarcoidosis who cannot tolerate steroids and who is developing ILD?
As with most questions about sarcoidosis, clear understanding of the relevant clinical context should first be established. While interstitial lung disease (ILD) is a common manifestation of sarcoidosis, it often can be safely monitored without treatment, and so radiologically identified sarcoid ILD...
How would you manage cardiac sarcoid with intolerance/contraindications to methotrexate, azathioprine, and mycophenolate/mycophenolic acid and that has proven refractory to adalimumab and infliximab as determined by PET?
I think it would be important to know the doses of the medications 'failed'. Similarly to allopurinol dosing and gout prophylaxis 'failures', I find most patients I see for consultation with this story are not on high enough doses, need combo therapy, or are not on the medication long enough. Meth...
When transitioning from romosozumab to alendronate or teriparatide to alendronate, is there a minimum amount of time that alendronate needs to be continued to prevent loss of BMD gains?
My personal approach is that the transition to an anti-remodeling drug like alendronate should be done ASAP to reduce the risk of losing new bone that was made with the anabolic drug. The length of use of alendronate should be consistent with our typical use of oral alendronate. Generally, no more t...
How do you manage a patient with SLE with acute bilateral sensorineural hearing loss refractory to high dose systemic and intratympanic steroids, normal MRI brain and APL labs?
Interesting, as I just saw a case almost exactly like this one (except my patient was unilateral)! I question whether systemic lupus erythematosus is truly the cause of the hearing loss. If immunologically induced (ie, autoimmune hearing loss), I'd expect to see at least some objective improvement o...
How do you approach screening for occult cardiac or tracheal involvement in a patient with relapsing polychondritis?
Hello! Dynamic CT and echo, if you have suspicion of vasculitis (physical exam, sx), a CTA can help. Happy to discuss your case.
Is it safe to use one TNF inhibitor (e.g., infliximab) in a patient who has had a severe allergic reaction to a different TNF inhibitor (e.g., adalimumab)?
The short answer is yes - it is ok to proceed with a different TNFi. First, it is important to determine whether the reaction was truly allergic or a nonspecific infusion reaction instead. If possible, obtaining a serum tryptase level at the time of the reaction can help clarify. Realistically, this...
In patients with livedoid vasculitis and chronic venous insufficiency on rivaroxaban, what therapeutic strategies—beyond compression and topical care—are safe and effective for controlling pain, ulceration, and edema?
My experience has been that aspirin 365 mg, plus persantine or trental daily, plus leg elevation for 45 min or so in mid-afternoon, will produce pain relief and onset of healing within about two weeks. Only infrequently have I had to resort to metformin as an added medication or use both trental and...
What would be the clinical role of SGLT-2 inhibitors for lupus nephritis given it has an indication for proteinuria related to CKD?
The benefit for SGLT-2 inhibitors at slowing the progression of kidney disease or death from cardiovascular causes had been well established in patients with diabetic nephropathy. Further studies continued to demonstrate benefit in non-diabetic, proteinuric kidney disease (HR, 0.72 (95% CI, 0.64-0.8...
How do you approach adjusting insulin pump settings in patients who have received intra-articular corticosteroid injections?
Managing steroid-induced hyperglycemia in patients with diabetes has always been a difficult problem, and guidelines are hard to come by. Glucocorticoids cause increased insulin resistance and an increased need for insulin. The steroid effect on glucose is greater in the post-prandial state than the...
