Do you refer all of your patients for EGD prior to initiation of atezolizumab/bevacizumab for advanced HCC?
Per the trial, this was required within 6 months of starting the study. However, in practice, I don't know that this strict rule would be necessary. For example, what if an EGD was done 10 months ago without varices? I don't think I would feel strongly about this. Similarly, if we could get one shor...
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 ...
Does oral Wegovy have a worse side effect profile compared to its injectable version?
From a clinical standpoint, I would say that oral semaglutide does cause more nausea and other GI side effects than injectable semaglutide for comparable doses. I am not aware of any randomized trials looking at this question, but there are single-center retrospective studies corroborating my impres...
In patients with sarcoidosis and persistently elevated liver function tests, when do you consider initiating ursodeoxycholic acid (UDCA)?
In patients with systemic sarcoidosis with predominantly elevated alkaline phosphatase, I would be suspicious for liver involvement of their sarcoidosis. If treatment of the systemic sarcoidosis with immunosuppression (typically initiated by Pulmonology or Rheumatology) are ineffective for improving...
How do you decide when to refer for gut-directed psychotherapy versus start pharmacotherapy in newly diagnosed IBS with prominent anxiety symptoms?
Pharmacotherapies like antispasmodics, antidiarrheal medications, or tricyclic antidepressants can be used to treat a specific symptom of IBS (e.g., diarrhea or abdominal pain). Gut-directed psychotherapy targets the entire gut-brain axis in dysfunction, treating multiple symptoms at once, as well a...
In patients with microscopic colitis, what do you recommend on stopping SSRIs?
First, make sure the problem is not NSAIDs, PPIs, or statins. Second, remember that the evidence linking SSRIs to microscopic colitis is not iron-clad. Third, if you want to do a trial of a different class of antidepressant, the evidence linking SNRIs to microscopic colitis is even less consistent.
How would you approach diagnosis of a patient with recurrent episodes of abdominal pain, severe myalgias, low grade fevers and urticaria?
Without the mEFV variant, from a rheumatologist viewpoint, the differential includes IBD, a periodic fever syndrome such as FMF or FCAS, and MCAS. Therefore, I would consider that workup with genetic testing (anyone can send!), fecal calprotectin, and MCAS eval with A/I. I don't think of urticarial ...
Would you begin semaglutide in a morbidly obese patient with intermittent elevations in ALT (100s) and with significant hepatic steatosis but without significant fibrosis?
How was fibrosis identified? Based on the information provided, if the rest of the serologic workup was negative for liver disease, I would be comfortable starting semaglutide. Its cross-disease benefits are likely to be highly impactful in someone we are assuming has MASLD. Liver biopsy would be us...
How many days prior to elective major surgery do you recommend holding oral GLP 1 R agonist therapy?
Zero. Or, I suppose, if you're having surgery early in the morning, one.This has gone back and forth, but the most recent guidance from the ASA (with other societies concurring) has been that most patients can continue their GLP medications as normal preoperatively, with higher-risk people being rec...
Are there any biomarkers that might indicate who might be responders to atezolizumab/bevacizumab for HCC?
Not at this time. Some preliminary studies are being done as ad hoc at this point and was not pre specified before the IMbrave study launching
