What is your approach to therapy for pulmonary sarcoidosis resistant to methotrexate?
The first question I ask myself in any situation dealing with "refractory" sarcoidosis is "Am I sure active inflammation from sarcoidosis is the cause of their symptoms?". Oftentimes, I will see patients referred for refractory disease who end up having other causes of their symptoms. If I am confid...
Do you consider the duration of lung/lobar atelectasis in your decision making while offering airway stents for malignant central airway obstruction?
Yes, always. We review old imaging to determine when there is a post obstructive pneumonia or collapsed lobe/lung secondary to endobronchial obstruction (extrinsic or intrinsic). The old teaching was that, if a lobe is down for more than two months, it is unlikely to be salvaged, even after the endo...
What is your perspective on the role of respiratory therapists in managing a patient who is dyssynchronous on their current mode of mechanical ventilation?
Yes, it’s in the scope of their practice to adjust vent settings for various reasons. At my practice, I work with them closely so I am aware of the changes being made. And this goes both ways. If I end up making changes, I make it a point to let the RTs know what changes I made.
Do you use prednisone in the management of patients with persistent respiratory symptoms following acute COVID-19 infection?
No, unless I note bronchial hyperresponsiveness on follow-up Pulmonary function tests (PFTs). What I've noted is a significantly high percentage of undiagnosed asthmatics who come into the light because of a more severe clinical course from covid. Use anti-fibrotics occasionally for fibrosis dependi...
Do you offer immunosuppression to patients with CTD-ILD with concomitant well controlled HIV?
With the widespread use of highly active antiretroviral therapy (HAART), we have definitely seen an increase in long-term HIV patients who now live long enough and with enough functional immunity to develop CTD-ILD or autoimmune ILD warranting the use of immunosuppression. However, these patients re...
How do you define severe hypoxic burden on home sleep testing?
There seem to be two questions here. First, can you measure hypoxic burden on a home sleep test? The answer is that technically it can be done without great difficulty. However, as far as I know, there are no home sleep apnea testing devices that offer hypoxic burden as an outcome measure. Thus gett...
Do you consider dual biologic therapy in patients with ABPA that remain steroid dependent despite the use of omalizumab?
The treatment of ABPA can be so challenging, but this is something that I have not seriously considered at this point. Unfortunately, in general, the evidence for biologics in the treatment of ABPA currently is heterogeneous. Furthermore, many studies are descriptive case reports/series or based on ...
How do you approach treatment of septated parapneumonic pleural effusions that do not satisfy traditional criteria for complicated effusion after diagnostic thoracentesis?
Septated effusion is a complicated effusion, whether it is empyema, parapneumonic, or malignant, and usually, they are exudative. By definition, untreated parapneumonic effusion will become empyema. Septations <4-6 week duration are usually fibrinous and can be lysed with tPa/DNase instilled through...
Do you routinely continue using TPA/Dornase for treatment of empyema, if there is accumulation of new sero-sanguinous output from the chest tube after the initial treatment?
In my practice, if there is an accumulation of serosanguinous output after initial treatment, further treatment with tPa/ dornase depends on several factors. Hct of drainage - if > 50%, will not give further dose. If a patient is coagulopathic or receiving anticoagulation for a medical condition af...
What is your approach to initial work up for a young patient with bronchiectasis?
I assume we are talking about patients in their 20s, 30s-50s who have had a HRCT with radiological bronchiectasis. It will be good to know if they have had clinical implications and symptoms of cough, infections, and mucus production. It will be good to know about multiorgan involvement like sinuses...
