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...
What criteria do you use to determine if a change is clinically significant while evaluating PFTs?
This can be determined using various criteria, including whether or not a measurement has dropped below certain severity thresholds and/or if the observed change is greater than one might expect through general variability. Various professional societies have recommended using the lower limit of nor...
Will you incorporate the use of tirzepatide in the management of patients with OSA?
Yes! However, the best methods to incorporate GLP-1s into the practice of Sleep Medicine have yet to be determined. Hopefully, our professional organizations can provide us with clinical practice guidelines to better direct our practice in this area.For those that have not had a chance to review, SU...
Do you routinely repeat imaging for PE after anticoagulation treatment to establish a new baseline?
We only do imaging if the patient is symptomatic still after a few weeks or has persistent chest pain or clinical signs of pulmonary hypertension. Rarely I have seen recurrent or progressive thromboembolic disease on anticoagulation. Another possible reason if the patient needs to go to surgery in t...
How do you approach dyspnea in a patient with seropositive rheumatoid arthritis with normal imaging findings but abnormal PFT findings (restriction, reduced DLCO)?
Pulmonary pathophysiological abnormalities are common in individuals with rheumatoid arthritis (RA) and respiratory symptoms. In individuals without respiratory symptoms, abnormalities may even be detected by lung function testing or high-resolution CT imaging. Any compartment of the lungs may be in...
Do you plan to use benralizumab to treat acute exacerbations of asthma or COPD associated with eosinophilia?
Currently, I do not use benralizumab for acute exacerbations of asthma or COPD, even with eosinophilia. Its role is in long-term maintenance for severe eosinophilic asthma, not in the acute setting where rapid-acting therapies are required. I’ll reconsider if emerging data support the benefit in exa...
How long after initiating mycophenolate do you wait before tapering prednisone off in patients with myositis-associated ILD?
Taper Pred after 6 weeks MMF tapering to prednisone 20 mg/day and hold this dose for 6-8 weeks monitoring for relapses. If no relapse, taper to Prednisone 10 mg/day.
If PFTs are done on different machines or different places, are the comparisons valid?
Pulmonary function test results might differ slightly when performed at different facilities due to staff engagement and coaching during respiratory maneuvers and machine calibration. Another important consideration is there may be differences due to use of body box plethysmography versus helium dil...
What’s your approach to an asymptomatic, hemodynamically stable patient with moderate spontaneous pneumomediastinum without pneumothorax and normal esophagogram?
Terrific question and, fortunately, an unusual occurrence with an estimated 1 in 30,000 hospital admissions (Barroso et al., PMID 37965408). The true incidence is likely higher as underdiagnosis may be related to individuals with mild symptoms who do not seek medical care, symptoms misdiagnosed and ...
How do you approach a patient with a solitary brain metastasis from small cell lung cancer s/p resection with otherwise limited thoracic disease?
This is rather an uncommon situation but can happen if a patient presents with a synchronous solitary brain metastasis (with or w/o symptom) and undergoes craniotomy and resection only to find out that it is small cell lung cancer. Additional information is needed on the volume of intra-thoracic dis...
