Do you perform routine interval lung cancer screening in non-smokers who are 1st degree relatives of patients with non-smoking related lung cancers with known EGFR mutations?
I would not. Although there may be a measurable increase in the risk of lung cancer detected in population studies, the absolute risk is probably far below the equivalent of even a low-risk, current or former tobacco user. This is a hard conversation to have with people who believe their risk to be ...
What is your approach to therapy in patients with progressive Scedosporium pulmonary infection who are not candidates for surgical debridement?
Scedosporium species are increasingly common clinical isolates in patients with bronchiectasis (both CF and NCFBE). There are precious few publications describing these infections in immune-competent hosts, but it seems that these infections tend to be symptomatic (rather than asymptomatic colonizat...
Do you recommend automatically starting CRRT anticoagulation when initiating CRRT if there are no medical contraindications to anticoagulation?
Great question. My practice is that we don't. However, I wonder if we should. In any case, it is not unreasonable not to give it at the beginning and start it if the patient clots daily or more often. I think bleeding episodes tend to be very dramatic at times and result in clouding our judgement a ...
How would you approach the workup and management of isolated inflammatory subglottic stenosis in a young previously healthy patient that is steroid responsive with a completely negative serologic autoimmune workup?
This is a relatively unusual situation in that idiopathic subglottic stenosis is typically not managed with systemic immunosuppression. The typical therapies are endoscopic and include dilatation (+/- intralesional corticosteroids), endoscopic resection, and cricotracheal resection. A recent large t...
What is your preferred biologic in children and adolescents with T2 high asthma?
It depends on patient age, biomarkers (IgE levels, eosinophil counts, FeNO, allergy testing results), comorbidities, what insurance will cover, and how frequently a patient can tolerate injections, adverse effects. Also, clinical outcomes such as wanting to improve FEV1 can play a role in the decisi...
Do you preferentially avoid use of piperacillin-tazobactam for empiric anti-pseudomonal coverage in hospitalized patients due to risk of nephrotoxicity?
The bulk of published data indicates that the onset of nephrotoxicity in patients receiving piperacillin-tazobactam plus vancomycin seldom occurs before 3 days of the combination. Thus, I do not object to initiation of this combination empiric therapy, but, as in all cases, therapy must be reevaluat...
How does your approach to subsegmental PE differ from segmental PE both diagnostically and therapeutically?
My approach to subsegmental PE and segmental PE generally tends to be very similar. I am aware of the CHEST guidelines which indicate patients can safely be observed with subsegmental PE, but like a recent study showed (Rouleau et al., PMID 37531107), uptake of these guidelines is slow and many pati...
Do add a macrolide for immunomodulatory effect in patients with macrolide-resistant M. abscessus?
I think using azithromycin is something that definitely can be considered, but on an individual basis; if there is significant bronchiectasis with exacerbations, then it makes sense to consider azithromycin; more likely to consider also if there are other microorganisms, especially Pseudomonas drivi...
What is your approach in differentiating IPAF (interstitial pneumonia with autoimmune features) versus "CTD ILD" in patients with serologic abnormalities but do not fulfill criteria for autoimmune disease?
Even for those of us who work in ILD clinics, this can be a challenging issue. The concept of IPAF (interstitial pneumonia with autoimmune features) was developed in 2015 jointly by the ATS and the ERS for study purposes and as such is somewhat helpful in the clinic. Much like classification criteri...
Have you incorporated the use of steroids for patients with severe community-acquired pneumonia?
Yes, the evidence is pointing toward starting steroids (hydrocortisone at 200mg total daily dose) early (in the first 24 hours) in patients with severe CAP who do NOT have influenza. In septic shock caused by CAP, steroid recs follow the septic shock guidelines. Dequin et al., PMID 36942789 showed t...
