How would you treat an asymptomatic patient with a positive Blastomyces antibody, evidence of prior granulomatous lung disease on imaging, and who may require immunosuppression in the future?
We practice in an area with a good bit of blastomycosis and rarely see a positive Blastomyces antibody, even in patients with culture-proven blastomycosis. The newer EIA antibody that MiraVista lab is doing may be more reliable. If the prior granulomatous lung disease has been worked up with negativ...
What are your top takeaways from IDWeek 2025?
The professional ID community is still strongly interested in the power of vaccines to prevent infectious diseases and improve the health of the world. New anti-fungal agents show promise for treating difficult mold infections Changing climate and increased mobility are shifting the traditional geo...
How do you manage gram-negative bacteremia in a patient with an aortic bypass graft, for whom there is low clinical suspicion for active graft infection?
This is a very nuanced question, and thus, there is no perfect answer. If there is low suspicion for graft infection and the bacteria is not commonly associated with biofilms (like a simple E. coli) and the bacteremia clears quickly, I would likely treat for a couple of weeks and monitor (and even c...
What is your typical duration and route of treatment for a lytic lesion in the metaphysis of a long bone secondary to MSSA, i.e., a Brodie abscess, following debridement in an immunocompetent patient?
For native bone osteomyelitis (including Brodie abscess) with residual infected bone after debridement, antibiotic therapy is usually recommended for 6 weeks from the date of last debridement. Data suggest that a duration of antibiotic therapy beyond 6 weeks is usually unnecessary if necrotic bone a...
Do you routinely use cefdinir for the treatment of common infections diagnosed in the outpatient setting such as CAP, uncomplicated UTIs?
Not routinely. More expensive than equally effective alternatives.
What is your preferred method for latent tuberculosis screening prior to outpatient hemodialysis initiation for a patient with new dialysis requirements?
Definitely Quantiferon testing. It can be done at the same time as the hepatitis B blood test. The patient does not have to come back and have it read a couple of days later.
Do you have to extend treatment for acute Lyme disease if a patient is on high dose steroids for another indication?
I am unaware of any evidence to support longer-term therapy in such a setting. I am quite sure no such study has ever been done. Standard therapy for early Lyme disease is 10 days of appropriate antibiotics. Extending to 20 days would likely do no harm to the patient, but may not be necessary, and t...
Do you routinely treat pregnant patients for latent tuberculosis or delay treatment until 2-3 months post-partum?
Guidelines from CDC, WHO, ATS/IDSA recommend delaying the treatment of latent TB in pregnancy until 2-3 months postpartum unless there is a high risk of progression to TB disease e.g. HIV co-infection. This is because the risk of hepatotoxicity from isoniazid is higher during pregnancy and in the ea...
Do you favor a certain NRTI to pair with dolutegravir and lamivudine in persons with HIV to minimize the risk of resistance to dolutegravir?
The data are strong to support DTG/lamivudine as a stand-alone regimen with low risk of resistance development as long as patients remain adherent, so there isn't necessarily a reason to add another NRTI. That said, the Beck et al., PMID 40898778 study would suggest that tenofovir is associated with...
What oral treatment options would you offer a patient with severe onychomycosis who is also on methotrexate for another condition?
I prefer pulsed terbinafine at 250 mg daily x1 week every other month. Dr. Zaias showed in a comparative study that pulsed terbinafine works as well as giving it daily for 3 months, and since the patient is only taking this for 1 week every other month, risks for hepatotoxicity are minimal.
