Would you perform screening for pulmonary hypertension in a patient who has biopsy-proven Sjogren's but has a centromere antibody?
Generally, the risk of pulmonary hypertension in Sjogren's is low - about 2% in a recent study using RHC for diagnosis (Coppi et al., PMID 40058609). There have been no studies linking Raynaud's to pulmonary hypertension risk in Sjogren's, although this is true in systemic sclerosis. So the real que...
What are some practical tips for when a patient's consistently stated goals of care do not correlate with their actions?
First, it's important to remember that most of us have inconsistent beliefs. We both want to lose weight, and we want to eat chocolate cake; we want to get an A, and we want to go to the party. So when we see inconsistencies in others' beliefs, rather than being judgmental, we should get curious. Ou...
What is your approach to a patient with undetectable MMR titers checked prior to or during immunosuppression and a history of MMR vaccination in childhood?
MMR titers are good correlates of protection. If any titer is undetectable it could be one of these situations: Primary failure. The components of the MMR have different efficacy. Two doses of appropriately given MMR will have 96+% against measles, but only 88% for mumps. Thus 1 in 10 appropriately...
Do you recommend maintaining the same monitoring interval of PFTs every 3–6 months with HRCT as indicated for patients with anti-MDA5 dermatomyositis, or do you recommend closer surveillance in this group?
Closer surveillance may be needed at diagnosis of ILD in anti-MDA5 DM at every 3 months for 1st year. But typically, in my experience, patients' symptoms progress faster than every 3 months, so rapidly progressive ILD is diagnosed clinically.
Do you utilize cytokine panels to guide treatment of patients with EGPA?
Whether biomarkers can guide treatment decisions or predict disease relapse is a critical area of study in ANCA associated vasculitis. However, efforts to identify biomarkers that are predictive in EGPA are at an early stage currently. There have been multiple negative studies of biomarkers being ab...
At what lab values (ferritin, TSAT%) would you offer IV iron therapy to patients with restless leg syndrome?
1. I am hopeful that practitioners will start understanding that ferritin alone is not enough to assess iron because of its acute phase reactivity. I like to order iron parameters after a 5-9 hour fast so the serum iron is not speciously elevated and get a ferritin and TSAT. If the ferritin is <30 a...
Do you accept a decline in eGFR during aggressive diuresis for heart failure if the patient is successfully decongesting, given data suggesting modest eGFR decline with improved congestion may still be associated with lower mortality?
Yes, I accept a modest decline in eGFR during diuresis in patients with heart failure. Previous studies of patients hospitalized with acute decompensated heart failure have shown that mortality and readmission rates are reduced by effective decongestion even if the creatinine rises. The study by Oka...
How are you using liquid biopsy in the routine management of your patients with metastatic NSCLC?
The dramatic improvement in the prognosis of metastatic NSCLC patients harboring targetable oncogenic genetic alterations with highly effective therapy has underscored the need for tumor molecular profiling. There have been numerous studies in the past decade assessing the performance of ctDNA (here...
How do you approach initial anticoagulant selection in hemodynamically stable hospitalized patients with newly diagnosed pulmonary embolism?
Low-molecular-weight heparin demonstrates the greatest benefit in patients with cancer-associated pulmonary embolism, intermediate-risk PE, and those requiring outpatient management. While LMWH shows superior efficacy and safety compared to unfractionated heparin across most patient populations, cer...
What is your approach to patients with chronic hypoxemic respiratory failure who have apparent higher oxygen needs during hospitalization but no clear acute/decompensated respiratory illness?
Will work them up completely for infection, PE, COPD exacerbation, heart failure/cardiac etiology. If no convincing reason for decompensation and they are stable, I will have them do a 6 min RT walk test to determine oxygen needs and have them follow up with PCP or pulmonary for further PFTs or othe...
