What is your approach to treating patients with dupilumab induced facial redness?
Literature is quite clear that the majority of these patients have Malassezia hypersensitivity as the etiology and the pathophysiology is essentially the same as seborrheic dermatitis. The IL-4 blockade allows upregulation of Th17 activity, which is the inflammatory pathway for seborrheic dermatitis...
Do you treat prosthetic joint infections after a two-stage revision arthroplasty with oral antibiotics for the full duration of therapy, assuming a susceptible oral option is available?
This is a hard one-I definitely think the data is there for PO, but until the IDSA recommendations change and the culture of practice changes it is hard to make the switch to doing a full regimen PO! I also think the accountability of IV antibiotics is useful -with the visiting nurse, weekly labs, i...
What are some immunosuppression regimens to consider in a patient with refractory cardiac sarcoidosis?
Unfortunately, there is no high quality data at this point to directly answer this question but here are some options. For patients who have only been treated with oral steroids, I would first consider the addition of weekly methotrexate at a dose of between 10 - 20 mg WEEKLY with supplemental folic...
When would you consider referring a patient with suspected cardiac sarcoidosis based on PET and MRI for endomyocardial biopsy given degree of patchy involvement, as opposed to initiating empiric immunosuppressive therapies?
I would avoid initiating empiric immunosuppressive therapies without a firm diagnosis of sarcoidosis. I will mention however that the latest Japanese Circulation Society criteria for the diagnosis of sarcoidosis do include criterion for the non-invasive diagnosis of likely cardiac sarcoidosis based ...
In patients with longstanding UC or Crohn's colitis, would you extend the interval of surveillance colonoscopy to longer than 3 years if they have had little inflammatory disease over the years and no other factors to increase their risk (ie, history of polyps, history of dysplasia, or family history)?
AGA Practice Update says you can go to 5-year interval. Murthy et al., PMID 34416977
Do you utilize soluble IL-2 receptor or ACE levels as serum biomarkers to monitor disease activity in pulmonary sarcoidosis?
I use ACE levels to monitor disease activity in patients who demonstrate elevated ACE levels at diagnosis of confirmed sarcoidosis and for which there is no other explanation for elevation of ACE. ACE normalizes with treatment and will increase again if/when the disease relapses. The literature indi...
How do you decide when to initiate medical workup (e.g., thyroid, B12, infection) in a geriatric patient experiencing new onset or worsening low mood?
It is important to distinguish between low mood, which can occur from a host of environmental stressors, and frank depression, and there are 3 ways to look at either in the older patient: Early onset depression in someone now older, and the patient feels the present one is exactly the same as previo...
How exhaustive (especially considering cost) should an immunological workup be for patients with extensive, recurrent, or deep seated Staph aureus infections without obvious immunocompromise (e.g. cancer, diabetes, steroids) or recurrent breaks in skin integrity?
Obviously, children with recurrent Staph aureus infections should be evaluated for both CGD (chronic granulomatous disease) and IgM deficiency. However, the majority of adults with recurrent SA infections do not have a known systemic immunodeficiency. We should keep in mind that Staph aureus is an a...
Would you stop denosumab in a patient with chronic kidney disease if they develop asymptomatic hypocalcemia after the injection?
No. Stopping denosumab leads to rebound bone resorption and loss of all gains. The hypocalcemia indicates insufficient calcium and/or calcitriol. Calcium intake should be 1,000-1,200 mg daily from food and/or supplements in divided doses with food.
Is there a serum potassium level for when you would recommend discontinuing potassium citrate in a patient with recurrent nephrolithiasis, hypocitraturia, and hyperkalemia?
I take hyperkalemia seriously, as cardiac effects do not correlate closely with serum levels. If evaluation does not reveal a correctable cause, I would decrease potassium citrate dosage to keep serum potassium below 5.0. Stephen B. Erickson, MD
