Would you ever consider switching a patient with an LVAD from warfarin to Eliquis, such as in the setting of recurrent GI bleeds?
In general, warfarin remains the agent of choice in VAD patients. However, in patients with INR non-adherence or recurrent GI bleeds, it is an option. In this situation, ensure that GI bleeding is stopped and start 2-3 days after warfarin is stopped. Monitoring with anti-factor Xa monitoring can be ...
Do you switch to an alternative agent for C difficile colitis for a patient with suspected infection and positive testing who continues to have >3 watery bowel movements daily despite multiple days of oral vancomycin treatment?
The question about switching to another agent for Clostridioides difficile (Cdif) colitis in a patient who tests positive for Cdif but continues to have diarrhea despite multiple days of oral vancomycin treatment does not include any information regarding the clinical status of the patient, the pres...
With OpenBiome no longer in operation, what is your current approach for obtaining FMT for inpatients with acute severe/fulminant C. difficile infection unresponsive to antibiotics?
Consider Rebyota by enema or flex sig, similar to what you had done with standard FMT.
How do you decide between anticoagulation and observation for an incidentally detected subsegmental pulmonary embolism in elderly patients with a history of gastrointestinal bleeding?
We face this conundrum not infrequently because subsegmental emboli are subject to high inter-reader variability, and the accuracy of the finding in isolation is suspect (Batayneh et al., Blood 2023). I once mentioned this to a radiologist who reads CTAs and was told, tactfully, that I was full of i...
What is your approach to the use of GLP-1 agonists in older adults with diabetes with or at risk of sarcopenia?
This is an important question to keep an eye on, given the broadening use and effectiveness of GLP-1 agonists for various conditions, especially diabetes, and for weight loss. Unfortunately, as is so often the case, major clinical trials in this area do not reflect the heterogeneity of older adults ...
In a patient with Zieve's Syndrome and alcohol related cirrhosis which antibiotic regimen is safe to treat H. pylori?
I am not concerned about a cirrhotic patient receiving a fluoroquinolone, macrolide, metronidazole, or doxycycline. The drug insert labels do not raise any particular concerns for these drugs’ use, even in Child Pugh class C cirrhosis. Yes, there is a theoretical potential for overdosing patients on...
For opiate-related ileus in the postoperative setting, at what point do you consider trialing methylnaltrexone?
I personally have never used this particular PAMORA for post-op ileus. Despite some promising phase 2 trials indicating potential benefit, several Phase 3 RCTs evaluating this drug specifically for post-operative ileus showed no benefit in preventing nausea/vomiting or speeding up time to discharge ...
Do you avoid peritoneal dialysis in cirrhotic patients with ascites?
There are two major concerns regarding the performance of PD in patients with ascites: the potential for fluid leakage at the site of the newly placed catheter and the perceived increased potential for peritonitis. In my experience, neither of these is a compelling reason to shy away from PD in a pa...
How do you choose VOWST versus REBYOTA after an antibiotic course for recurrent C. difficile?
Just keep the patient on PO vanco 125 mg BID. That's plenty. Your GI tract would have to contain over 50 liters of fluid to dilute the vancomycin to a concentration below that of the C. difficile. Also, initial treatment should be longer than 10 days. I never understood the studies with a 10-day DOT...
What is your preferred approach in treating recurrent bleeding from GAVE?
If repeated APC has not helped, I ask our advanced endoscopists to perform RFA. If it is a nodular GAVE, then banding is another option.
