What interventions do you find helpful for the initial management of functional GI disorders in primary care?
TCAs seem to help modulate pain, particularly at low doses.
Do you prefer formal testing to establish a diagnosis of SIBO/IMO over empiric treatment?
Great practical question. I prefer formal testing for several reasons: Even though postprandial bloating and distention along with change in bowel habits are the hallmarks of SIBO/IMO, they are non-specific and can be caused by myriad of other organic causes. A normal breath test would direct the a...
How do you decide when to use acid-suppressive medications for GI prophylaxis when patients are on prolonged corticosteroid therapy?
We only use acid-suppressive medications for GI prophylaxis in patients treated with corticosteroids when they have additional risk factors for upper GI bleeding. Risk factors include concomitant NSAID or antiplatelet therapy, history of GI bleeding or peptic ulcer, age over 60 years, prednisone dos...
Can fatty liver disease present with elevations in alkaline phosphatase without other liver enzyme elevations (AST and ALT)?
It is very atypical but can occur. Patients usually have elevations in aminotransferases (usually ALT higher than AST) and there can be very mild concurrent elevations in alkaline phosphatase. An isolated alkaline phosphatase elevation should however prompt a more extensive serological work up as we...
In a young patient who was vaccinated to chickenpox as a child (no previous varicella infection) should the patient receive a shingles vaccine prior to starting Rinvoq?
Yes. The vaccines are different and current vaccine is to prevent zoster for patients who have been previously exposed to varicella or vaccinated for varicella.
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...
In patients with F2/F3 fibrosis, would you start Resmetirom if they had normal liver enzymes?
Yes, it would be reasonable, especially if you can prove that they still have significant steatosis (such as a CAP of >300 db/m) or active MASH on liver biopsy, as Resmetirom works by directly removing fat from the liver. The lack of liver enzyme elevation is not a reliable sign to rule out steatohe...
When starting GLP-1 R agonist therapy for weight loss purposes, how do you counsel patients on duration of treatment therapy?
I counsel people that I expect this to be lifelong therapy (similar to how we don't stop blood pressure medications when blood pressure comes down to normal on them because it will go back up, we don't stop GLP1RA when we get to our weight goals, as our weight will go back up when they are stopped)....
Would you consider the use of prophylactic antibiotics in patients admitted with decompensated cirrhosis with AKI with Cr>1.2, with ascitic fluid protein <1.5 without SBP and/or hyponatremia/Bili >3?
Is this in generalized cases or cases of GIB? If GIB, yes, I would consider it. In just generalized cases, there is no real role for empiric antibiotics.
Should GLP-1 agonists be held during chemotherapy?
I think there are several aspects to this question. First, is there evidence that as a class GLP-1 RAs increase the risk of cancer or worsen prognosis during cancer? I could find nothing to raise concerns about outcomes. One recent report even showed a decreased risk of some cancers with GLP-1 RA co...
