What is your protocol for transitioning to oral anticoagulation post-thrombolysis for pulmonary embolism?
My answer has multiple parts."Thrombolysis" is not all the same. As studied in stroke treatment, alteplase causes marked fibrinogen depletion and coagulopathy (prolonged PT, aPTT), whereas tenecteplase doesn't so much (Huang et al., PMID 26514192).So, if alteplase was used (systemic or reduced cathe...
Do you recommend early oral nutrition when managing diabetic ketoacidosis?
There are many benefits to starting enteral feedings in patients undergoing treatment for DKA. Once insulin is being infused, the use of enteral nutrition will help suppress ongoing ketosis. Also, restarting nutrition will help prevent weight loss during recovery. Of course, some patients have condi...
Does your institution have formal policies or work flows to reduce unnecessary IGRAs ordered for patients on biologics?
We have developed a multi-specialty working group to implement this as a lot of unnecessary testing is getting done. This will include having a 2-3 question screening pre start of biologics, and then annually to asses risk, that we hope will be incorporated into the visit or an order set.
Is there a role for biologics to improve lung function in patients who have severe asthma with daily symptoms and reduced lung function but do not experience frequent exacerbations?
Biologic therapy in severe asthma not only reduce exacerbation but also improve lung function based on several RCT.
Would you consider adding or switching to pirfenidone for a patient with progressing UIP (based on imaging and PFTs) who is currently on nintedanib?
Yes, I would consider it. There's some recent literature addressing this, which indicates switching may be associated with disease amelioration. Why might it work? Not super clear, perhaps biologic differences or maybe driven by better compliance. Smarter people than me could probably speak to the r...
Do you perform routine interval screening for renal angiomyolipomas in patients with sporadic LAM?
The occurrence of angiomyolipomas (AMLs) in sporadic lymphangioleiomyomatosis (S-LAM) is less common compared to tuberous sclerosis complex-related LAM (TSC-LAM). One study showed that up to 50% of patients with S-LAM developed AMLs, whereas 100% of TSC-LAM patients were affected (Yeoh et al., PMID ...
What would be your second pressor of choice if patients with LVOT obstruction remain persistently hypotensive on phenylephrine?
In patients with LVOT obstruction who remain hypotensive despite treatment with phenylephrine, choosing an appropriate second pressor requires careful consideration of the hemodynamic goals and the specific pharmacologic properties of available agents. Here are a few points: While the specific liter...
Have you noticed poor response to Tyvaso DPI compared to the nebulized form in PH-ILD?
I find that patients with PH-ILD who have symptoms of dry cough at baseline do better when initiated on Tyvaso nebulizer. I have found the nebulized form of the medication easier to initiate, with better toleration of titration. I often transition my patients to the DPI formulation for convenience o...
How do you complete brain death testing in patients who cannot tolerate apnea testing and are unable to transport for ancillary testing?
The short answer is that you cannot. Brain death diagnosis requires the presence of 3 conditions: persistent coma, absence of brainstem reflexes, and lack of ability to breathe independently. If portions of the clinical exam or apnea test cannot be performed, ancillary testing is necessary to make t...
What is your approach to tapering therapy in patients with pulmonary sarcoidosis who are asymptomatic with stable pulmonary function and imaging?
We generally do not use weight-based dosing for treating sarcoidosis but often will use 20 mg daily (0.25 mg/kg) as a starting point. If a patient is newly started on prednisone, then we may use a gradual taper 20 mg daily for 1 month, then 15 mg daily for 1 month, then 10 mg daily until they are re...
