What is your approach to choosing a particular advanced therapy based on patient or disease factors when initiating treatment for moderate-severe IBD?
The selection is based less on relative efficacy and safety (aside from JAKs) and more on the patient: Age, gender, family history, and co-morbidities. Younger males: more concern regarding lymphoma with thiopurines. Young women: If contemplating pregnancy would consider biologics vs small molecule...
How do you incorporate intestinal ultrasound in the care of patients with inflammatory bowel disease?
The use of intestinal ultrasound (IUS) has significantly impacted how I care for patients with IBD. In an established patient with IBD, I typically monitor disease activity every 6 months with a reliable tool (IUS, calprotectin, colonoscopy, or enterography), even when patients are asymptomatic, as ...
What role do you feel there is for antibiotics in the management of severe perianal Crohn's disease?
There isn't high quality data to answer this. I use antibiotics for perianal disease in the setting of an abscess, inflammatory stranding in the surrounding or during period of increased activity (purulent drainage, pain). One should always consider if an abscess needs to be drained (+/- EUA) or a s...
How would you approach new-onset large vessel vasculitis in a young patient with Crohn's disease?
Patients with Crohn's Disease (or IBD) can develop features of large vessel vasculitis or even other forms of vasculitis. The first consideration in a young patient would be determining the type of vasculitis--whether there is a distribution and clinical picture suggestive of TAK. It is important to...
What diet do you recommend for patients with inflammatory bowel disease?
This is a good question and very commonly comes up. The first step is really understanding what the expectations and goals are. If the goal is to achieve remission in people with inflammation who are symptomatic and want to use diet as monotherapy or in conjunction with meds, I discuss various thera...
Would you avoid risankizumab in a patient with stricturing Crohn’s complicated by granulomatous bronchiolitis with stenosis who had to stop ustekinumab due to hemoptysis?
Unless there had been a rapid and dramatic beneficial response of the Crohn’s disease to ustekinumab, I would have little appetite for trying another IL-blocker. A different mechanism, like JAK, might be worth trying, but the serious pulmonary complication probably warrants steroid therapy. One coul...
How do you adjust medications for patients with eosinophilic esophagitis who responded to budesonide or PPI, and when do you repeat EGD?
Repeat EGD after BID PPI is normal- do you decrease to once-a-day PPI? When to repeat EGD if ever? I try to decrease to once daily in the morning, but if so, I repeat an endoscopy 3 months later to make sure histologic remission is still maintained. After response to Budesonide, continue life-lo...
In an infant whose mother resumes TNF inhibitor therapy (e.g., adalimumab, infliximab, certolizumab) after delivery and is breastfeeding, do you recommend delaying live vaccinations?
IgG-based biologic therapies - including TNF inhibitors - are all considered compatible with breastfeeding, since IgG passes only minimally into breast milk. Given these agents are proteins, the minimal drug that is transferred is unlikely to remain intact (or active) with passage through the infant...
How would you approach diagnosis of a patient with recurrent episodes of abdominal pain, severe myalgias, low grade fevers and urticaria?
Without the mEFV variant, from a rheumatologist viewpoint, the differential includes IBD, a periodic fever syndrome such as FMF or FCAS, and MCAS. Therefore, I would consider that workup with genetic testing (anyone can send!), fecal calprotectin, and MCAS eval with A/I. I don't think of urticarial ...
What factors do you consider when a patient with acute severe ulcerative colitis flare responds to inpatient Infliximab, and you are deciding whether to switch to subcutaneous or continue IV maintenance dosing of Infliximab?
Patients admitted with acute severe ulcerative colitis typically have higher drug clearance related to significant fecal loss of infliximab through a highly inflamed colon, leading to low levels and often the need for dose escalation. There have been studies showing that infliximab levels in severe ...
