Would you consider leaving fever untreated in patients with sepsis to potentially enhance immune responses and antimicrobial efficacy?
In light of the review article attached (Tilanus et al., PMID 41113323), there is some data reviewed supporting that fever is actually therapeutic. Four articles are of special interest in the review. Two are from the 70s, before sepsis was defined as it is today. Two are in the last 15 years, but o...
Do you generally recommend device exchange/removal in patients with gram positive bacteremia in the setting of intra-aortic balloon bump or other mechanical circulatory devices?
I am assuming in this case that the patient has a mechanical circulatory support device such as an LVAD, IABP, or another implantable device, and has developed gram-positive bacteremia. No further details about the device type or clinical scenario are provided. In such cases, device removal is recom...
What is your approach to monitoring of inflammatory markers during treatment of native vertebral osteomyelitis?
As long as the patient is clinically stable and CRP is coming down, there is generally no need for follow up imaging. Key reference: Kowalski et al., PMID 16779743.Also, good to remember that ESR is a very expensive test which basically measures fibrinogen (may cost $500 or more since it has to be r...
Do you still recommend adjunctive corticosteroids for tuberculous meningitis in light of more recent data showing heterogeneity in clinical outcomes?
Though there is some disagreement in study results, a number of randomized trials and one meta-analysis support the benefit of mortality when steroids are used as adjunctive therapy for tuberculous meningitis. The use of steroids continues to be the recommendation of the WHO. In most situations, the...
What is your approach to work up and management of a patient with advanced HIV and poor adherence to therapy presenting with dysphagia and fever?
I would first do an HPI (is the dysphagia for both liquids and solids?), then a quick physical exam, with a full set of vital signs. In terms of basic blood work, I would get a CBC and BMP, liver function tests, a set of blood cultures, a chest x-ray, along with a viral load and CD4 T cell count, wh...
Do you still use itraconazole for Aspergillus prophylaxis in heart transplant recipients, or have you transitioned exclusively to posaconazole?
We haven't used itraconazole for Aspergillus prophylaxis in heart transplant at my institution since I have been an attending (2021).
Do you recommend doxycycline over azithromycin as first-line treatment for outpatient community-acquired pneumonia in otherwise healthy adults, given rising macrolide resistance rates?
Yes - our county antibiogram shows >50% resistance of Streptococcus pneumoniae to azithromycin, and thus if there is a true concern for bacterial infection, I recommend doxycycline.
For hospitalized patients with confirmed viral respiratory infections who clinically improve but remain PCR-positive, how long do you maintain isolation precautions?
This is a great question and one that routinely comes up for patients, their families, and staff. Precautions should be continued until symptoms improve and for a minimum of 14 days after the onset of signs and symptoms. This is especially important for patients who can spread virus to individuals t...
Have you used Karius to work up fevers in the hospital when the source remains unknown?
This is a tricky question because Karius is an expensive test, which many experts believe should not be used for its negative predictive value (and I have anecdotally seen negative results where infection was still present, and infections/organisms detected of very unclear significance). I like to u...
Do you recommend treating Candida albicans on urine culture from an indwelling catheter in a patient with septic shock?
In a patient with septic shock, one is typically obligated to treat all things until further culture data is back, etc. If there are other clear causes of shock, I would not treat the candida (though I would try to change the catheter ASAP). If the patient is extremely ill and no other sources of in...
