What is your approach to management of elevated liver enzymes in patients who recently started treatment with tocilizumab?
This is an important concept because anyone using tocilizumab will eventually wrestle with this question. The question, though, does not tell you whether this is the first time a practitioner sees the liver enzyme elevation, or how high the liver enzymes rose. Since everyone should have had a lipid ...
How long do you anticoagulate for cirrhosis patients who have portal vein thrombosis extending to the mesenteric veins?
I recommend indefinite anticoagulation for most patients with portal vein thrombosis, and at least 3-6 months if there are risk factors for bleeding. Once they complete anticoagulation for the first 6 months, I re-evaluate their risk of recurrent thrombosis vs bleeding, and if there is an underlying...
How do you approach managing nausea and GI side effects when initiating methotrexate?
There are several strategies to minimize nausea and gastrointestinal symptoms with the use of methotrexate. The medication can be taken with food, just not with caffeine. The dose can be split throughout the day it is taken such as half the dose in the morning and the other half in the evening. The ...
How do you approach managing depression symptoms in patients who have had repeated high risk of bleeding?
Overall, evidence suggests that while SSRIs do increase the risk of bleeding. The absolute risk of a bleeding event remains low and is usually not serious. A 2017 meta-analysis by Laporte et al., suggested that overall bleeding risk is increased by at least 36% while other meta-analyses suggest that...
When and how should we be stopping GLP-1 Receptor Agonist/Dual Agonist therapy?
I usually continue for 3-4 years, the tapering down slowly over 1 year period, buy then the set point for energy expenditure and appetite likely is changed.
When and how do you do testing for disaccharidases on GI biopsies?
You can send two biopsies from the 3rd portion of the duodenum for enzyme assays, but it might be easier just to do simple disaccharide absorption tests.
Do you prescribe respiratory muscle training (RMT) devices to patients with dysphagia?
We encounter dysphagia frequently in our patients with Parkinson's disease and other movement disorders. If there are any concerns about swallowing or aspiration, my first step is to refer to Speech Therapy for evaluation, and I defer to their expertise for specific treatments from there. That said,...
What factors make you consider an EUS before embarking on an ERCP for concern for type 1 Sphincter of Oddi dysfunction, (appropriate biliary symptoms, dilatation of ducts with no stones on MRCP, and liver labs suggestive of cholestasis)?
When clinical presentation is not typical for SOD and imaging raises the question of an anatomical/structural cause, or history of idiopathic recurrent pancreatitis, a diagnostic EUS may be helpful in this context. If the clinical presentation with LFTs and imaging meets criteria for type 1 SOD, EUS...
Do you recommend checking anti-drug antibodies for patients on TNF inhibitors?
This is a very good question with direct clinical practice implications. I do not check or follow anti-drug antibodies when using TNF inhibitors for the treatment of rheumatoid arthritis or psoriatic arthritis. There are reports that suggest, on a group level, that these antibodies, if present, impa...
When and how should we use biomarkers (i.e., CRP, stool calprotectin, mAb levels) to guide or optimize medical management of Crohn’s disease or ulcerative colitis?
The principal clinical applications of biomarkers in IBD are as follows: Assessment of severity and prognosis during a flareup. Monitoring the efficacy of treatment. Determining the probability of postoperative recurrence of Crohn’s disease (i.e., the high negative predictive value of FPC for anasto...
