What strategies do you use to prevent overcorrection of serum sodium in patients with severe hyponatremia and adrenal insufficiency when initiating glucocorticoid therapy?
Treatment of hyponatremia due to adrenal insufficiency with glucocorticoid therapy may result in overcorrection of serum sodium due to suppression of ADH and resultant water diuresis. Therefore, serum sodium, urinary osmolality and urinary output should be closely monitored. A brisk water diuresis w...
What findings on routine monitoring PFTs prompt you to pursue HRCT in your patients with SARDs?
That’s an excellent question, and the strategy might vary somewhat by the specific SARD, but in general, in any SARD patient undergoing annual PFTs, the presence of any of these should prompt an HRCT to evaluate for the development of ILD. FVC drop ≥ 10% DLCO drop ≥ 15% Moderate decline in FVC (5-9...
When do you consider PET/CT to evaluate for an occult source of infection in patients with persistent bacteremia if TTE/TEE does not show evidence of endocarditis?
Great question. Generally, I consider PET/CT to evaluate for an occult source of infection in patients with persistent bacteremia if TTE/TEE does not show evidence of endocarditis, in the following scenarios: Persistent bacteremia ≥72 hours. TEE was negative or nondiagnostic. No source identified o...
Do more fractionated regimens reduce severe toxicity over SBRT in patients with ILD and early-stage NSCLC?
I personally think fewer fractions are safer, such as 30 Gy x 1 instead of 10 Gy x 5, for patients with advanced COPD or ILD. Why? It's because each time a burst of ionization events is delivered to pulmonary tissues, a wound is created that recruits an inflammatory response, which can exacerbate th...
Would you recommend antifungal treatment or observation without therapy in an immunocompetent patient with a pulmonary nodule who underwent malignancy workup and was found to have yeast forms consistent with histoplasma on GMS stain?
We have seen a number of patients who have had a lung biopsy for a solitary pulmonary nodule to exclude the diagnosis of cancer. When histoplasmosis is identified by pathology, we obtain a urine histoplasma antigen as well as a careful history and exam, and some lab tests for immunosuppression. If n...
When do you consider a trial of steroids for acute hypoxemic respiratory failure when there are no other clear indications for its use (i.e., COVID, COPD, organizing pneumonia, etc.)?
We will consider a trial of systemic corticosteroids in patients with moderate-to-severe acute respiratory distress syndrome (ARDS) within 14 days of onset—even when no other clear indications are present (such as COVID-19, COPD, or organizing pneumonia). This is supported by the 2024 American Thora...
How do you monitor for pulmonary toxicity for patients on trastuzumab deruxtecan?
Eligibility criteria for T-DXd trials were based on clinical history and not on objective findings such as PFTs or radiographic criteria. Therefore, risk for factors for T-DXd-related ILD or other pulmonary toxicity are not at all clear, although they may emerge with larger pooled safety analyses an...
What are your thoughts on trending beta-hydroxybutyrate once a diagnosis of DKA is already established?
Beta-hydroxybutyrate (BOHB) ≥3.0 mmol/L is highly sensitive and specific for diagnosing DKA and can be measured through serum or point-of-care testing. However, its role in monitoring treatment response and determining resolution remains debated. The American Diabetes Association recommends continui...
Do you continue PJP prophylaxis indefinitely in patients on rituximab maintenance therapy?
Risk for PJP infection is usually in the context of moderate-high dose corticosteroid therapy or low T cell counts.
Do you routinely prescribe dry powdered inhalers over metered dose inhalers for the purpose of addressing carbon emissions?
Appreciate this question because we often forget just how inextricable the link is between human health and climate health. More specifically, carbon emissions from inhalers worsen the respiratory conditions they are intended to treat. Inhaler prescriptions filled by CMS beneficiaries in 2022 were e...
