Do you recommend surveillance lumbar punctures for patients with Mollaret's meningitis after diagnosis or in between clinical episodes?
No. My focus with these patients is to establish the diagnosis, which is often difficult, with false-negative CSF PCR tests, and then do everything I can to prevent and alleviate the attacks. I see no role for surveillance LPs because either the patient is better clinically or they are not, and CSF ...
What factors should be prioritized when deciding the timing of CIED extraction in patients with high surgical risk or multiple comorbidities?
I'll do my best to respond, though the question isn’t entirely clear to me. If the intent is to determine which patients should be prioritized for CIED extraction, the key consideration is whether the benefits outweigh the risks. The most straightforward case is persistent bacteremia, especially in ...
Do you routinely consider FDG PET/CT imaging for workup of fever of unknown origin?
The landscape of FUO and IUO and our clinical approach to diagnosing its cause has changed significantly over the past several decades. More sensitive microbiologic screening for infectious etiologies, including syndromic molecular panels and next-generation sequencing are now clinically available a...
What is your approach to dental prophylaxis for patients on biologics?
My approach has been to not recommend antibiotics prior to routine dental care for patients on biologic therapy. I'm not aware of any compelling evidence or guidelines supporting preventive antibiotic treatment for such patients. Of course, there may be exceptions to this. Antibiotic prophylaxis mig...
What is your approach to anal pap screening among MSM with HIV, and if routinely recommend, starting at what age (assuming access to HRA)?
We taught our nurses and patients how to do self-collection, which cut down on the amount of time it takes. Multiple guidelines for HPV have been revised in the past few months based on more recent studies (although the emotional reaction to having multiple of my patients diagnosed with anal cancer ...
What factors do you consider when deciding between monotherapy with an antipseudomonal cephalosporin and combination therapy in ICU patients with Pseudomonas aeruginosa bloodstream infection who are not in septic shock?
In a patient who is critically ill, combination therapy can be used if there is concern that there may be a drug-resistant organism. In that case, a combination regimen can be used while awaiting the susceptibility test results. The combination choice should be based on the resistance patterns of th...
What agent and for how long would you treat a patient with asymptomatic azole-resistant C auris candiduria who is planning to undergo a urological procedure?
I would be cautious here. If there are reasonable MICs to fluconazole (SDD but achievable), this would be preferred. Intravesical amphotericin is a good option. But, if this were impossible to achieve, I would be reluctant to use IV amphotericin in any formulation, since there's a risk of harm, and ...
What is your preferred agent for fungal prophylaxis in a patient post lung transplant with abnormal LFTs?
Isavuconazonium tends to cause less elevations in LFTs.
How do you manage resistant infections that persist after stopping antibiotic therapy in patients with non-CF bronchiectasis?
It depends on what is meant by resistant infections; if this means multi-drug resistant bacteria that remain present after treatment ends and when symptoms have returned to baseline, there are many things to consider. First, has the person had many exacerbations before? Or do they have minimal sympt...
For a patient on appropriate treatment for invasive aspergillosis, how do you determine if and when it is acceptable to reintroduce a TNF inhibitor that likely contributed to their acquisition of the infection but is considered essential for control of their inflammatory condition?
There is no established answer to this question. The reintroduction of a TNF inhibitor must be individualized based on the clinical situation of the patient under consideration. There are two critical questions. First, how much does the patient need the inhibitor”? The more the patient is dependent ...
