In patients with RA on methotrexate and a TNF inhibitor who develop PJP pneumonia, how long do you hold immunosuppression before restarting therapy?
I would typically hold immunosuppression until the patient has completed therapy unless they had significant respiratory failure, in which case I would await full recovery. The patient should be placed on appropriate PJP prophylaxis prior to resuming therapy.
How do you approach a patient with recurrent VTE who develops VTE again after reduction of apixaban to 2.5 mg bid?
Several factors play into this decision for me. Is the patient obese? Obese patients tend to give me pause for dose-reduction of DOACs. As such, half-dose apixaban may have been relatively underdosed for an obese patient and I would not call it DOAC failure, rather I would increase the dose to usua...
How well does a negative non-contrast MRI of the brain exclude metastasis in a patient with squamous cell carcinoma of the lung?
I don't think the question has enough information to give a good answer. For example, if it was a T3, N2 NSCLC, or a small cell, then "yes" I'd repeat the MRI with contrast. On the other hand, if it was a T1, N0 NSCLC, then "no", I wouldn't. In other words, if I thought there was a real risk of havi...
What steroid durations do you use for the treatment of acute, chronic, and drug-induced eosinophilic pneumonia?
For acute eosinophilic pneumonia, these are often high doses of IV methyl prednisone in the hospital, and assuming that the exposure or risk is mitigated, I would taper these down over a short period of time after discharge. Chronic eosinophilic pneumonia, I treat briefly with steroids but quickly t...
What specific clinical and echocardiographic thresholds lead you to taper/de-escalate pulmonary hypertension therapy before liver transplant?
The goal in pulmonary hypertension therapy pre-transplant is to fulfill the MELD exception criteria in terms of mean pulmonary artery pressure, pulmonary vascular resistance, as well as right ventricular function by echo. Once those criteria are satisfied, maintain those PH therapy doses until the t...
What is the goal oxygen saturation for patients with COPD and pulmonary hypertension?
Although an oxygen saturation target of 88–92% is commonly used in patients with COPD to reduce the risk of oxygen-induced hypercapnia, a higher saturation goal is appropriate in patients with pulmonary hypertension associated with COPD. In this population, we generally aim for an oxygen saturation ...
What is your approach to empiric treatment of achromobacter infections?
Achromobacter is a Gram-negative bacterium in the Burkholderia order. This pathogen is significant in immunocompromised patients, such as those with cancer or Cystic fibrosis, and is seen with bacteremia or causing pneumonia. They can also be associated with foreign device infections. Typically, the...
Would you consider leaving fever untreated in patients with sepsis to potentially enhance immune responses and antimicrobial efficacy?
In light of the review article attached (Tilanus et al., PMID 41113323), there is some data reviewed supporting that fever is actually therapeutic. Four articles are of special interest in the review. Two are from the 70s, before sepsis was defined as it is today. Two are in the last 15 years, but o...
Do you generally recommend device exchange/removal in patients with gram positive bacteremia in the setting of intra-aortic balloon bump or other mechanical circulatory devices?
I am assuming in this case that the patient has a mechanical circulatory support device such as an LVAD, IABP, or another implantable device, and has developed gram-positive bacteremia. No further details about the device type or clinical scenario are provided. In such cases, device removal is recom...
Do you recommend doxycycline over azithromycin as first-line treatment for outpatient community-acquired pneumonia in otherwise healthy adults, given rising macrolide resistance rates?
Yes - our county antibiogram shows >50% resistance of Streptococcus pneumoniae to azithromycin, and thus if there is a true concern for bacterial infection, I recommend doxycycline.
