What is your approach to explaining the role of the microbiome to patients with inflammatory arthritis?
The gut microbiota play a central role in modulating the inflammatory response. This is especially relevant to inflammatory arthritis, where the pathogenesis is quite well understood, especially as it relates to arthritis associated with inflammatory bowel disease. We also know that the diet is the ...
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
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...
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...
When do you consider de-escalating therapy such as dupilumab in eosinophilic esophagitis?
It is first important to recognize that EoE is a chronic condition. In a patient whose EoE is successfully being treated (whether it be with PPI therapy, swallowed steroids, food elimination, or dupilumab), the disease will invariably become active again over time if therapy is stopped. This is why ...
Which patients, if any, do you revert back to ultrasound screening for HCC after prior diagnosis/definitive treatment of HCC?
I don't revert back to U/S for these patients ever. It's not dissimilar from colorectal cancer screening - once you have colon cancer, it's not appropriate to use iFOBT or stool DNA screening anymore - it's lifelong colonoscopy screening. Likewise, for HCC, I continue to use AFP plus cross-sectional...
Do you avoid terlipressin for patients with hepatorenal syndrome who have an elevated bilirubin level?
The CONFIRM trial excluded patients with Grade 3 acute on chronic liver failure (due to increased risk of pulmonary complications). There have also been concerns raised that using terlipressin on liver transplant candidates might improve their MELD score enough to jeopardize their spot on the waitin...
How would you resect an 11mm sessile gastric polyp?
I would first study the surface morphology and pit pattern. Specifically look for central depression or ulceration and signs of early cancer (such as Irregular or amorphous pit pattern). If central depression or irregular or amorphous pit pattern is present, I would consider en bloc resection with E...
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 ...
How do people approach non-HIV patients with hepatitis B, a negative Hepatitis B E antigen, normal LFTs and relatively low HBV DNA between 2000-20000?
Treatment of chronic Hep B is recommended to prevent maternal-fetal transmission, reactivation during chemotherapy, recurrence after liver transplantation, and in patients with decompensated cirrhosis. Treatment has been shown to reverse fibrosis and cirrhosis. Specifically referring to the above sc...
