If a patient has persistent ascites requiring diuretics after TIPS, at what point do you consider re-evaluation of TIPS?
Some may still require some diuretics, particularly if lower extremity edema is an issue post-TIPS. Otherwise, if paracentesis is needed ~6 weeks after TIPS and the patient is free of HE, then consider IR dilating the TIPS further. When TIPS is for ascites, IR should really start with a small calibe...
How do you manage anticoagulation/antiplatelet therapies with strong indications for uninterrupted therapy in setting of urgent procedures?
If anticoagulation is absolutely contraindicated because of the bleeding risk of the procedure, then "bridging" will usually make the most sense, most of the time, with low molecular weight heparin such as enoxaparin. If dual antiplatelet agents are contraindicated, particularly in the first month a...
What is your advice to patients with IBD who are on biologic therapies and planning for pregnancy?
Biologics are effective therapies for many autoimmune conditions, including IBD. The best outcome of a pregnancy is if a patient is in remission at the time of conception, which means she does not stop her therapy to get pregnant. Indeed, there are studies on women with nonspecific infertility who w...
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.
Would you consider anti-IL-5 therapy (mepolizumab or benralizumab) to either prevent or treat the more severe manifestations of eosinophilic granulomatosis with polyangiitis, such as "infiltrative" (e.g., cardiomyopathy, pulmonary infiltrates, or gastroenteritis) or "vasculitic" (e.g., neuropathy, palpable purpura, or glomerulonephritis)?
Yes, I would consider early starting biologics for infiltrative EGPA.
Can rapid weight loss following GLP1 R agonist therapy lead to postprandial hypoglycemia and if so, what are the treatment options outside of dietary modifications?
This is a very interesting question but I am not sure that there is a clear published answer. Of course, we know that this class of medications can contribute to hypoglycemia in patients on insulin or SUs and in that situation the management would involve cutting back on the insulin or SU or decreas...
How do you manage a patient with Ogilvie's syndrome presenting with a cecal diameter above 12 cm unresponsive to conservative management with electrolyte correction, decompression by flexible sigmoidoscopy, and rectal tube placement?
While neostigmine has traditionally been used in this setting, it often faces pushback from both the hospital and pharmacy due to the need for cardiac monitoring. Additionally, it's not suitable for long-term use. Instead, I’ve been using pyridostigmine, which does not require cardiac monitoring and...
Is there benefit to aggressively treating hemochromatosis in a patient who has already progressed to cirrhosis at the time of diagnosis?
The short answer is yes, there is a benefit to treating iron overload in a patient with hereditary hemochromatosis (HH) with cirrhosis. HH involves at least five mutations, most commonly in the HFE gene (common variants include C282Y and H63D), leading to hyperabsorption of iron and progressive accu...
How do you choose between resmetirom and semaglutide in the treatment of MASH?
I write a disclaimer to start, because use of resmetirom ($5,000 per month) and semaglutide ($1,600 per month) at this time cannot be used across the board with any patient with hepatic steatosis. It's important to highlight how we characterize a patient's metabolic dysfunction associated steatotic ...
What role do you feel there is for antibiotics in the management of severe perianal Crohn's disease?
Without access to biologics you still should have access to a thiopurine. That has some efficacy and was all we had prior to biologics along with chronic antibiotics.
