What is your approach to the management of chronic GI bleeding from AVMs in an elderly patient on DOAC for atrial fibrillation?
I would definitely strongly consider the left atrial appendage occlusion device in these patients. While usually these devices (such as Watchman) do require anticoagulation for about 45 days until the device has an endothelial layer form on it (we usually confirm with a CT scan or TEE), there are so...
Would you consider a combination of anti-TNF therapy and azathioprine upfront in a young male with Crohn’s disease considering its risk of lymphoma in the era of several advanced therapies?
Definitely, TNF + IMM hasn’t been beaten in efficacy. If the patient is in clinical and endoscopic remission at 6-12 months with good IFX levels, then they can stop the IMM.
What is your treatment approach to a patient with budesonide refractory microscopic colitis and multiple sclerosis?
First job is to be sure the colitis is not attributable to any medication, particularly ocrelizumab. Meanwhile, have you given an adequate trial of bismuth?
For patients with HCC that have stable disease on immunotherapy alone, would you consider adding bevacizumab at the time of disease progression and continue immunotherapy?
Yes, this is applicable to patients who are on single agent immunotherapy, since the atezo/bev combination carries different mechanism of synergistic potential than single agent immunotherapy. Notably, currently approved second line agents are indicated after progression on sorafenib, however, curre...
Do you recommend restarting a GLP-1RA after bariatric surgery if the patient tolerated it before the surgery?
While there are no clear recommendations on whether/when to resume GLP-1 RA after bariatric surgery, current 2025 guideline statements (ASMBS, ADA, AACE, Obesity Society) and expert consensus documents suggest the following approach: Hold GLP-1RA in the acute perioperative period. For daily-dosed ...
When do you send for genetic testing (e.g., SPINK1, PRSS1, CFTR) in a patient with recurrent or chronic pancreatitis without an obvious etiology and how does it impact your management?
I offer and discuss getting genetic testing in patients with idiopathic recurrent acute pancreatitis or chronic pancreatitis, more frequently in younger patients. Impact of testing can help identify undiagnosed CFTR patients, for whom further CF evaluation and management including options to try new...
In patients treated with infliximab, do rates of immunogenicity vary based on underlying disease (RA, IBD, sarcoidosis, etc) and/or baseline disease activity?
Yes, rates of infliximab immunogenicity appear to vary based on underlying disease, with evidence showing higher rates for RA than IBD and spondyloarthritis, and tend to increase with higher baseline disease activity. Most patients tend to develop anti-drug antibodies within the first year, but this...
What is your approach to management of elevated liver enzymes in patients who recently started treatment with tocilizumab?
This is an important concept because anyone using tocilizumab will eventually wrestle with this question. The question, though, does not tell you whether this is the first time a practitioner sees the liver enzyme elevation, or how high the liver enzymes rose. Since everyone should have had a lipid ...
How long do you anticoagulate for cirrhosis patients who have portal vein thrombosis extending to the mesenteric veins?
I recommend indefinite anticoagulation for most patients with portal vein thrombosis, and at least 3-6 months if there are risk factors for bleeding. Once they complete anticoagulation for the first 6 months, I re-evaluate their risk of recurrent thrombosis vs bleeding, and if there is an underlying...
How do you approach managing nausea and GI side effects when initiating methotrexate?
There are several strategies to minimize nausea and gastrointestinal symptoms with the use of methotrexate. The medication can be taken with food, just not with caffeine. The dose can be split throughout the day it is taken such as half the dose in the morning and the other half in the evening. The ...
