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 plan to integrate exercise programs after adjuvant chemotherapy in patients with colon cancer, given the results of the CHALLENGE trial?
The CHALLENGE study demonstrated that structured exercise following adjuvant chemotherapy significantly benefits patients with resected high-risk stage II or stage III colon cancer. The study's success hinged on its mandatory behavioral-support sessions. Unlike the control arm, which received only h...
With the growth of non-alcoholic beverages (e.g., NA beer, liquor, etc), how do you approach a patient's consumption of these products in the setting of alcohol related liver disease?
This is definitely a challenging conundrum to deal with. Historically, even the NA beverages would have 0.5% alcohol, so they weren't truly NA. With time, that has seemingly changed. Regardless, my approach is the same. I strongly advise against the idea that NA beverages are allowed. Mostly because...
How do you approach the workup for a patient with imaging showing features suggestive of cirrhosis?
It is important to clarify what features of the imaging are resulting in this diagnostic impression. Liver nodularity without other findings of cirrhosis is non-specific and does not make a diagnosis of cirrhosis. An incidental finding of a nodular liver with normal liver enzymes and normal platelet...
What are some helpful tips to identify and optimize visualization of the common bile duct on abdominal POCUS?
Good question! The common bile duct (CBD) can be difficult to visualize in general, but optimizing the gallbladder exam will also help to optimize the CBD. I am cautious about ruling out choledocholithiasis with POCUS, though a retrospective 2014 study showed that POCUS can be helpful in ruling out ...
