Do you use an antibiotic with antitoxin activity for the entire duration of therapy for patients with necrotizing MSSA or MRSA pneumonia or just until definitive clinical improvement?
I misread the question. I assumed a necrotizing S. aureus infection meant a necrotizing skin and soft-tissue infection. I’m not sure how “necrotizing pneumonia” is being defined here. Regarding MRSA pneumonia with toxin-mediated tissue injury, there are data suggesting that linezolid may yield bette...
How do you weigh the risk of urinary catheter or fecal management system placement with that of soiling sacral wounds?
This question is an important question that arises for many of our bed-bound and poorly mobile patients, as sacral wounds commonly develop due to pressure injury. They become very challenging to treat due to fecal and urinary contamination, which can lead to further infection. Fecal and urinary dive...
How do people approach non-HIV patients with hepatitis B, a negative Hepatitis B E antigen, normal LFTs and relatively low HBV DNA between 2000-20000?
Treatment of chronic Hep B is recommended to prevent maternal-fetal transmission, reactivation during chemotherapy, recurrence after liver transplantation, and in patients with decompensated cirrhosis. Treatment has been shown to reverse fibrosis and cirrhosis. Specifically referring to the above sc...
What is your approach to iron supplementation in patients with an active infection?
In patients with active infections, I generally avoid intravenous iron due to the potential for promoting pathogen growth, a practice supported by cautions from nephrology and gastroenterology society guidelines. However, evidence for the risk of infection with IV iron is inconsistent, underpowered,...
Would you recommend empiric coverage for vancomycin-resistance enterococcus in an unstable patient with sepsis, multiple comorbidities, and a recent ICU stay in a high VRE prevalence unit, despite recent cultures without growth of VRE?
I would go back to the assessment of community onset vs hospital onset as to when the sepsis is "setting in." If patient is coming from the community, hasn't had antibiotics in the last 90 days, hospitalized in the last 90 days, has no positive microbiology for VRE in the last year, then no, I would...
Do you routinely prescribe linezolid to patients who are concomitantly on methadone?
There are a few ways to interpret this question: Potential for serotonin syndrome with possible interaction between methadone and linezolid. Potential for further QTc prolongation with the addition of linezolid to methadone. Whether empiric oral antibiotics (when IV antibiotics could be used) are ...
How do you approach using fecal microbiota therapy for recurrent Clostridioides difficile infection in immunocompromised patients?
We generally do not do the single donor FMT via colonoscopy, that was popular 5-10 years ago. We do offer both the oral and enema-based products, with a slight preference for the oral-based product due to ease of use.
How has your approach to managing asymptomatic bacteriuria in kidney transplant patients changed in light of a recent meta-analysis showing no significant differences in pyelonephritis, symptomatic UTI, or graft loss between patients treated with antibiotics and those who were not treated?
The referenced meta-analysis has not dramatically impacted my approach to asymptomatic bacteriuria (ASB) in kidney transplant recipients (KTRs). The included trials clearly show no benefit (and possible harm) in treating ASB at time periods >2 months post-transplant. So we do not screen and we do no...
Do you routinely give combination antifungal therapy for invasive mold infections?
The data on triazole single agent versus triazole plus echinocandin for the treatment of invasive aspergillosis are limited. I do not have a standard approach. I generally use a triazole alone, but will use the combination for initial treatment in patients with severe and/or rapidly progressive dise...
How do you approach patients who continue to experience pruritus and ongoing concern for persistent scabies despite having completed appropriate treatment?
Pruritus can not uncommonly continue in patients for 6 weeks or more after infestation is managed. High-dose antihistamines may be of some benefit. Consider if there is an ongoing untreated exposure that the patient has not thought of or cannot/will not share with you. Not all people infested with s...
