How do you approach a patient on anti-TNF with positive Quantiferon (previously negative) with negative chest x-ray and no symptoms?
Prior to routine screening for latent TB for patients receiving or about to receive TNF inhibitor therapy, there were reports of miliary TB developing after initiation of TNF inhibitors. Therefore, one cannot say that a negative chest x-ray and no symptoms means the patient is not at risk for develo...
How do you approach a patient with IgG4-related disease who has failed rituximab and mycophenolate and continues to rely on high-dose steroids?
Most cases of IgG4-RD respond to rituximab similar to the steroid treatment. When there is a lack of response to moderate dose steroid or rituximab, either the diagnosis is not IgG4-RD or the manifestation is not due to active IgG4-RD. In many cases, if treatment is delayed, fibrosis takes over the ...
How do you approach the treatment of Crohn's colitis in the setting of immunosuppression for liver transplant?
Good question, as additional immune suppression can increase the risk of infection. The anti-rejection drug mycophenolate can cause diarrhea, which could mimic a Crohn’s flare. I individualize Crohn’s therapy in a liver transplant patient. What type of Crohn’s do they have? What meds were they on pr...
How do you decide whether to place an NGT or PEG tube in patients with dysphagia precluding adequate PO nutritional intake?
There are several factors that go into the decision of PEG tube vs continued nutrition via a nasogastric feeding tube(NGT). Anticipated time to recovery of oral pharyngial function (especially in the most common underlying illness, which is stroke). NGT can stay in place for up to 2 months without...
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...
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...
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...
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 ...
