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 ...
Do you use lactulose in acute liver failure, particularly in patients on continuous renal replacement therapy (CRRT) for ammonia or toxin clearance?
Generally lactulose should be avoided in the situation given limited benefit as well a tendency for ileus in ALF and potential for lactulose to cause bowel distention.
Do you have any concerns about lower extremity compression (e.g., compression stockings, intermittent pneumatic compression, etc.) worsening ascites in a patient with portal hypertension?
This is an interesting question, and I have to admit, not one I've thought about regularly. When I think of lower extremity compression and the contraindications, portal hypertension and ascites are not contraindications that immediately come to mind. I do understand the reasoning behind the questio...
What is your treatment algorithm for management of retroperitoneal fibrosis that does not respond to high-dose glucocorticoids?
There are a number of caveats to this. Is the retroperitoneal fibrosis biopsy-proven and/or IgG4 disease ruled out? If a case is refractory, I first question whether the diagnosis is correct and will often biopsy in this situation with more than an FNA biopsy. The second question is how long have t...
How long do you typically treat patients with phentermine for weight loss and what clinical markers do you follow?
Phentermine has been available since 1959 and remains an affordable and effective medication option added to a full lifestyle-based weight management plan. In people who are generally healthy and without contraindications to the medication, I have had patients used in at least intermittently for sev...
How do you diagnose and manage suspected opioid-induced esophageal dysfunction?
Patients with opioid-induced esophageal dysfunction have symptoms of most often, chest pain or dysphagia, with manometric findings of EGJ outflow obstruction, type 3 achalasia, or esophageal spasm/hypercontractile/jackhammer esophagus. When manometry suggests EGJOO or type 3 achalasia, in our practi...
When would you phlebotomize patients with secondary hemochromatosis, such as due to NAFLD/cirrhosis?
My simple answer is “rarely, if ever” (but it can get much more complicated). Related to hepcidin changes, patients with chronic liver disease frequently have elevated serum ferritin and transferrin saturation, more so with alcoholic liver disease and non-alcoholic fatty liver disease. It is far fro...
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...
What are your vaccine recommendations while patients are on biologics?
Live vaccines are best completed at least a month before initiation of biologics when these are appropriate (e.g., MMR, chickenpox, yellow fever). The data on non-live vaccines is limited. I personally think that some degree of protection is better than none. I will not interrupt biological therapy ...
Do you consider holding PPIs in patients hospitalized with infections like pneumonia or C. diff colitis?
My practice is to try to get patients off PPIs if at all possible, and the hospital can be a good time to have that conversation with them. This is assuming no active indication for them (recent ulcer/upper GI bleed, H.pylori therapy, etc.) Use of PPIs has been associated with a higher incidence of ...
