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 recommend anti-fungal treatment for aspergillus infection for a patient with an incidental finding of worsening ground glass opacities and enlarging nodules on CT chest with positive BAL galactomannan, elevated aspergillus IgE and IgG in an otherwise immunocompetent host with no respiratory symptoms?
No, I would not recommend antifungal treatment in this case. The patient, as described, does not seem to have invasive aspergillosis, chronic necrotizing aspergillosis, or allergic bronchopulmonary aspergillosis, so I don't believe antifungal treatment is indicated. There may be other details of the...
What has been your experience with tecovirimat for monkeypox?
I thought it worked well in 2 patients of mine with rectal Mpox. However, the clinical trial did not confirm this, and it was a lot of trouble to get TPOXX going with consent, investigational drug, etc so we have abandoned use here.
Under what circumstances do you recommend use of antibiotics during end-of-life care?
I use antibiotics at the end of life for palliation of pain and suffering after discussion with the hospitalist, family, and patient, if possible.
What is the best alternative oral therapy for treatment of non-severe pulmonary nocardiosis in an immunocompetent patient with sulfa allergy?
We have been using linezolid for this indication, based on a paper from ARUP Labs.Schlaberg et al., PMID 24247124
Do you recommend the use of ampicillin/ceftriaxone for prosthetic valve endocarditis due to ampicillin-susceptible Enterococcus faecium?
The prognosis for Enterococcus faecalis endocarditis is generally better than that for Enterococcus faecium, primarily due to antibiotic susceptibility patterns. It is fortunate to have an ampicillin-susceptible strain of E. faecium in this case of prosthetic valve infective endocarditis. In general...
Do you treat complicated pneumonia with a drained empyema longer if Streptococcus anginosus is cultured, either in isolation or with other organisms, compared to cases in which it is not?
Targeted antimicrobial therapy for any bacterial etiology of an empyema will be individualized for each patient but a general duration of 4-6 weeks. I would not consider strep anginosus differently in this regard. What I am looking for is adequacy of drainage with clinical improvement. Radiographic ...
When would you consider glucocorticoids as adjunctive therapy for for community-acquired pneumonia outside of the ICU setting?
Thank you for bringing this new study to my attention; I hadn't seen it yet. After reviewing the article, my practice regarding steroids remains unchanged. While the trial was well-executed, and it is laudable to see such research coming out of a limited-resource setting, that environment differs si...
What specific criteria or patient conditions would make you hesitant to use fluoroquinolones early in the treatment course for managing MSSA joint infections with oral antibiotics?
For MSSA joint infections, I have moved away from using FQ to using high-dose cephalosporins as a step-down therapy, particularly cefadroxil 1 g twice daily, given less frequent dosing/increased adherence. Considering the risk-benefit analysis, I prefer using FQ as an oral option in polymicrobial an...
How would you approach treatment of latent TB for patients who cannot tolerate rifamycins or isoniazid due to allergy, intolerance, or drug-drug interactions?
Levofloxacin or moxifloxacin. Duration is 6-9 months.
