Is there any evidence to support further uptitration of dobutamine beyond 5 mcg/kg/min for patients with advanced HF and/or cardiogenic shock, or should further investigation into potential MCS be considered at that point?
When a patient with acutely decompensated heart failure and shock is exhibiting insufficient perfusion in spite of a given level of support, whether pharmacologic or mechanical, it is appropriate to pause and ask why. Options at this point could include an escalation of inotropic therapy (dose escal...
How do you manage hypercalcemia in sarcoidosis despite being on immunosuppressive therapy?
Let us accept, first, that the individual does not have emergent levels of elevated calcium (equal to around or greater than 14 mg/dl) and concerning symptoms of the following systems: neurological (e.g., weakness, confusion, delirium), renal (e.g., polyuria, polydipsia), gastrointestinal (e.g., los...
What is the preferred four-drug regimen for initial treatment of pan-susceptible tuberculous meningitis, given the need to achieve optimal CNS penetration?
I will defer to the guidelines for the specific regimen. One general issue I would like to address is the idea of "CNS penetration." Since we don't routinely do brain biopsies in humans to truly assess levels of antimicrobials in the brain/spinal cord/meninges, many people think that "CSF levels = C...
Would you recommend starting tolvaptan at 7.5 mg per day, which is half the typical starting dose, to reduce the risk of overcorrection in an inpatient with SIADH and a serum sodium level of 122 mEq/L?
If it is for SIADH, I always start with 7.5 mg. See this, my fellow and I put together years ago. Dosing in SIADH: A Tale of Two Tolvaptans If it is for CHF, I would start with 15 mg as those patients are so pre-renal, their distal delivery is so impaired, and tolvaptan is limited by that. I haven't...
Do you start inhaled treprostinil outside a pulmonary hypertension indication in a patient with IPF and ongoing FVC decline despite antifibrotic therapy?
The phase 3 data show efficacy with a high discontinuation rate. Of course, it's not FDA-approved, so I wouldn't start it until the FDA approves it.
In light of recent measles outbreaks in the US, would you recommend an MMR booster for immunocompetent patients born before 1957?
I would not recommend a measles vaccine for a person born before 1957. This year has been chosen because people before born before 1957 have a very very high likelihood of having had measles because virtually all children got this highly contagious disease. On the other hand, there is no harm to get...
Would you initiate antifibrotic therapy in a patient with CTD-ILD experiencing worsening symptoms and declining lung function, despite no clear evidence of fibrosis on CT scans?
If the predominant findings on CT were ground glass opacities and/or nodules without any evidence of fibrosis on CT, I would not start with an antifibrotic and, instead, would start with immunosuppression as a first-line agent. Based on the American College of Rheumatology (ACR) and American Thoraci...
How would you approach anticoagulation for a patient with acute bilateral pulmonary emboli related to malignancy, but with a concomitant cavitary lung mass experiencing episodic, small-volume hemoptysis?
This is an interesting question to which we need to apply the art of medicine, weighing the risks and benefits of treatment. The major fatal events in this exact scenario are: Recurrent PE from undertreatment. Sudden massive hemoptysis after aggressive anticoagulation. The physician's management s...
How do you counsel patients on use of creatine monohydrate supplementation during a hospitalization for acute rhabdomyolysis from intense physical training?
I was a primary care doctor for the military for a few years. We regularly saw patients presenting with rhabdomyolysis from intense physical training. A standard question for all that present with this is whether supplements are being used. While there isn't a direct linkage to say that the use of c...
What is your approach to volume resuscitation in patients who are third spacing fluids?
In patients with significant third-spacing (e.g., due to capillary leak in sepsis, severe pancreatitis, hypoalbuminemia, etc), we prefer balanced crystalloids (e.g., Lactated Ringer’s) as the first-line fluid for initial resuscitation in hypovolemic or septic shock with third-spacing. Typical initia...
