IBD Updates: Probability of Needing a Stoma with Crohn’s Disease, “CEASE” anti-TNF study, Extending Tofacitinib Response Time

AH Everhov et al. Inflamm Bowel Dis 2022; 28: 1160-1168. Open Access! Probability of Stoma in Incident Patients With Crohn’s Disease in Sweden 2003-2019: A Population-based Study

In a nationwide Swedish cohort of 18,815 incident patients with a minimum 5 years of follow-up, 652 (3.5%) underwent formation of a stoma. The 5-year cumulative incidence of stoma formation was 2.5%, with no differences between calendar periods  (2003–2006, 2007–2010, and 2011–2014).

This study captured data from 1317 patients (including 927 patients stopping infliximab and 390 patients stopping adalimumab) to develop risk prediction models.  “The authors confirm many of the high risk, albeit rather intuitive, factors that are associated with the risk of relapse, including younger age, younger age at diagnosis, smoking, upper gastrointestinal tract involvement, longer disease duration, absence of concomitant immunosuppressant use, previous anti-TNF failure, and absence of clinical remission.”

The editorial notes that even in the lowest risk group, more than 20% had risk of relapse within 1 year; in addition, stopping therapy increases risk of not recapturing remission with restart of treatment. “Stopping anti-TNF therapy is a highly personalized treatment decision and is one that carries considerable risks…therapeutic discontinuation of TNF antagonists should be reserved for the very small minority of patients who are in deep remission, have a strong desire to stop treatment, have no (or very few) characteristics of high-risk CD, can tolerate a substantial disease flare, and are fully informed of the risks of therapeutic withdrawal.”

WJ Sandborn et al. Clin Gastroenterol Hepatol 2022; 20: 1821-1830. Open Access! Efficacy and Safety of Extended Induction With Tofacitinib for the Treatment of Ulcerative Colitis

Graphical abstract below shows that 52.2% of patients who did not achieve clinical response to 8 weeks’ treatment with tofacitinib 10 mg BID in the induction studies achieved a clinical response following extended induction (delayed responders). At Month 12 of OCTAVE Open, 70.3%, 56.8%, and 44.6% of delayed responders maintained clinical response and achieved endoscopic improvement and remission, respectively. Corresponding values at Month 36 were 56.1%, 52.0%, and 44.6%.

My take: By extending the treatment induction to 16 weeks to determine response (rather than 8 weeks), the authors showed that 75% of patients with ulcerative colitis in the initial cohort respond to tofacitinib.

Using Spot Urine Sodiums

Posted on by

A recent study (AKN Pedersen et al. JPEN https://doi.org/10.1002/jpen.1593) shows the utility of obtaining urine spot sodiums in patients with an ileostomy. Thanks to Kipp Ellsworth for sharing this reference.

Full link: A Single Urine Sodium Measurement May Validly Estimate 24‐hour Urine Sodium Excretion in Patients With an Ileostomy

Background: Sodium deficiency in patients with an ileostomy is associated with chronic dehydration and may be difficult to detect. We aimed to investigate if the sodium concentration in a single spot urine sample may be used as a proxy for 24‐hour urine sodium excretion.

Design: In this prospective, observational study, we included 16 adult individuals: 8 stable patients with an ileostomy and 8 healthy volunteers with intact intestines

Key finding:

  • There was a high and statistically significant correlation between 24‐hour natriuresis and urine sodium concentrations in both morning spot samples (n = 8, Spearman’s rho [ρ] = 0.78, P = 0.03) and midday spot samples (n = 8, ρ = 0.82, P = 0.02) in the patients with an ileostomy.

My take: In patients with ileostomy (and also short bowel syndrome), periodic urine sodium values (from morning or mid-day) will help detect subclinical sodium depletion.

IBD Update January 2015 (Part 1)

Posted on by

1. From the recent Advances in IBD Conference, Healio Gastroenterology reports on Dr. Baldassano’s update on PLEASE study which examined enteral nutrition in comparison to anti-TNF therapy.  Here’s the link: Enteral Nutrition Outcomes (Thanks to Kipp Ellsworth for this reference)

Here’s an excerpt:

Citing the findings from the Pediatric Longitudinal Study of Semi-Elemental Diet and Stool Microbiome (PLEASE), Baldassano demonstrated that greater mucosal healing was achieved in CD patients on exclusive enteral nutrition compared with partial enteral nutrition therapy. In this prospective cohort study, 38 children received enteral therapy with defined formula diet and 52 controls received anti-TNF-alpha therapy. The enteral nutrition group was further stratified to evaluate mucosal healing on a more restrictive diet; one subgroup received 80% to 90% of total caloric needs from enteral therapy, of which 14% achieved induction of remission at 8 weeks, the other subgroup received 90% to 100% of total caloric needs from enteral therapy, of which 45% achieved remission, and 62% of controls achieved remission.

3. Standardized use of fecal calprotectin (here’s the link -from KT Park’s Twitter feed):

Fecal calprotectin -use for identifying IBD and for identifying relapse risk

4. Inflamm Bowel Dis 2014; 20: 2247-59. Study examined factors associated with infliximab clearance.  Higher clearance noted with low albumin, high body weight, and the presence of antibodies to infliximab (ATI).  The authors note that higher concentrations with dose escalation are more likely when the dose interval was shortened than by increasing the administered dose.

5. Inflamm Bowel Dis 2014; 20: 2260-65. “Natural History of Perianal Crohn’s Disease After Fecal Diversion.”  Despite greater use of biologics, only 15 of 49 patients reestablished intestinal continuity between 2000-2011.  In this group of 15, only 5 remained reconnected and 3 of these 5 patients had procedures to control sepsis.  The likelihood of sustained intestinal continuity remains low in patients who have required a diverting procedure.
