What is the recommended fungal workup in an immunocompromised patient after 5 days of persistent fever?
For any patient with fevers, I focus significantly on any symptoms that a patient might have, like headache, diarrhea, and sinus symptoms, and work up a differential diagnosis based on possible pathogens in this area. If I am not finding anything, I would obtain a CT chest/abd/pelvis, as both invasi...
Is a history of Zoster ophthalmicus a contraindication to starting upadacitinib?
A history of HZO (herpes zoster ophthalmicus) or herpes zoster in any dermatome is a relative contraindication to the use of upadacitinib or any JAK inhibitor. HZO is often a very unpleasant disease with pain, ocular discomfort, and vision loss, so the chance of reactivation should be minimized. The...
Would you start treatment for MAC in a patient with nodular bronchiectatic disease who has demonstrated radiographic progression but remains asymptomatic and smear-negative?
My default answer would be yes; this is a sign of progressive disease that will get worse without treatment. Having said that many things could be considered while making the decision, including patient preferences. First is there another cause? Does the patient have an exacerbation of bronchiectasi...
What approaches can we take to initiate therapy and improve survival rates in patients with HLH?
At our institution, we have comprised a multidisciplinary team to help treat these patients. The team or "HLH task force" as we like to call ourselves is comprised of a clinical immunologist, rheumatologist, dermatologist, critical care physician, hepatologist, BMT attending/hematologist, infectious...
Do you recommend routine ophthalmologic exam for all patients with hypervirulent Klebsiella pneumoniae bacteremia?
The incidence of endogenous endophthalmitis due to Klebsiella bacteremia, especially due to hypervirulent K. pneumoniae strains, has been increasing. Klebsiella endophthalmitis is associated with poor visual outcomes Several studies, primarily from Asia, have described risk factors for developing en...
Do you consider holding PPIs in patients hospitalized with infections like pneumonia or C. diff colitis?
My practice is to try to get patients off PPIs if at all possible, and the hospital can be a good time to have that conversation with them. This is assuming no active indication for them (recent ulcer/upper GI bleed, H.pylori therapy, etc.) Use of PPIs has been associated with a higher incidence of ...
How do you decide whether to empirically cover Pseudomonas for pneumonia in hospitalized patients?
The decision to empirically cover Pseudomonas aeruginosa in pneumonia among hospitalized patients depends on the pneumonia type (community-acquired pneumonia, CAP vs. hospital-acquired pneumonia, HAP), disease severity, etiology, and specific risk factors. For Community-Acquired Pneumonia (CAP) Pa...
In patients with SLE do you have concerns about using trimethoprim-sulfamethoxazole (Bactrim) because of a potential risk of lupus flare?
I agree with Dr. @Dr. First Last . I have had too many SLE patients over the years show up in my office with a severe flare from TMP/SMX. We have too many alternative antibiotics these days, including for PJP prophylaxis, so sulfonamide antibiotics should be avoided in SLE patients. The typical scen...
What is your approach to symptom management in patients with infectious diarrhea?
When it comes to infectious diarrhea, I would consider a short course of loperamide for symptomatic relief, provided that my suspicion for C. diff colitis and/or dysentery is low. Antimotility agents in the setting of toxin-producing infectious diarrhea can increase the risk of toxic megacolon (in C...
Do you treat empirically for malaria in a febrile returning traveler from a high-transmission area with a negative rapid diagnostic test while awaiting thick and thin blood smear confirmation?
I would not routinely treat empirically for malaria in a clinically stable returning traveler with a negative RDT (rapid diagnostic test) while awaiting urgent thick and thin smears. However, a negative RDT does not rule out malaria. If the first smear is negative but suspicion remains, smears shoul...
