What infections should we rule out in patients who develop diarrhea on immunotherapy?
Immunotherapy is known to be associated with immune-mediated diarrhea and colitis (IMDC). However, it remains unclear whether cancer patients undergoing immunotherapy are at a heightened risk for Clostridioides difficile colitis infection (CDI). A retrospective study focusing on patients treated wit...
What antibiotics would you use for empiric treatment of a brain abscess in patients allergic to penicillin, metronidazole, and vancomycin?
Linezolid/Bactrim/Ceftaroline?
Do you recommend antibiotic prophylaxis for an ESKD patient with a tunneled dialysis catheter who is planned for a dental procedure?
I do not. Which procedures require antibiotic prophylaxis has always been a very confusing issue for me. It also seems to change often. However, with dental procedures, the main organism responsible for bacteremia is streptococcus of viridans group which is an unlikely cause of line infection. I thi...
Would you consider prophylactic antifungal treatment prior to immunosuppressive therapies in a patient with previously treated pulmonary coccidiomycosis and residual parenchymal changes?
If the pulmonary coccidiomycosis was treated in the past, I would not necessarily prescribe prophylaxis, but that also depends on the meaning of "residual parenchymal changes.” If you’re referring to post-inflammatory fibrotic changes, then prophylaxis likely is unnecessary. If you’re referring to c...
Do you routinely recommend suppressive antibiotic therapy for patients with spinal hardware infections who have undergone surgical debridement with retention of hardware?
Executive Summary: "State-of-the-Art Review: Diagnosis and Management of Spinal Implant Infections" was published in Clinical Infectious Diseases, December 15, 2024 issue, by Tai and colleagues from the University of Minnesota, Mayo Clinic, Hospital for Special Surgery (New York) and the University ...
What is your approach to treatment of patients with fulminant C difficile infection who required ileostomy creation or colectomy?
Great question. If the entire colon has been removed, I do not see a role for oral vancomycin.
For patients with spinal hardware infections, in what circumstances do you recommend 12 weeks over 6 weeks of antimicrobial therapy?
Extrapolating from PJI data, I tend to treat longer, but not always IV if there is an oral option after initial IV therapy. A big blurry line is when do oral antibiotics stop being for treatment and start being suppressive? Anyone I'm considering for long term suppressive antibiotics, really gets a ...
What are your top takeaways from ID Week 2024?
I thought there were a number of talks highlighting both the progress we’ve made and the needed areas of improvement in respiratory viruses. Some particularly good talks were by Barney Graham (Plotkin lecture), a talk on H5N1 by Timothy Uyeki (Enders lecture), a talk by Fiona Havers (from CDC), and ...
Would you consider stepping down from an echinocandin to azole therapy prior to the end of an initial six-week course for fluconazole-susceptible Candida albicans endocarditis in the absence of valve surgery?
I would not step down to fluconazole prior to completing a six-week course of echinocandin therapy. Fluconazole has poor activity against Candida biofilms in contrast to the echinocandins. Fluconazole monotherapy has also been associated with poor outcomes in endocarditis. Admittedly, most of our un...
Is there a role for chronic suppressive oral or inhaled therapy for recurrent Burkholderia cepacia pneumonia causing frequent hospitalizations in a patient with severe bronchiectasis with or without underlying cystic fibrosis?
In certain cases, certainly, suppression may be the optimal role but in conjunction with modification to the immunosuppression. Generally, the immunosuppression will need to be lowered to allow for cellular immunity to combat the infection. Other factors include whether the gemovar is a more aggress...
