ICN Travel Toolkit -Tips for Patients with Inflammatory Bowel Disease

Posted on by

ImproveCareNow’s Patient Advisory Committee: ICN Travel Toolkit – a collection of personal stories, plus tips and techniques for traveling with IBD – written by members of the ICN Patient Advisory Council (PAC).

In addition to the tips offered by the PAC (see below), I would recommend that those travelling keep a succinct medical summary with the following (minimum):

  • Diagnosis and extent of disease
  • Other medical problems
  • Physician (contact info)
  • Allergies –food/medicines
  • Current list of medications including dosage and frequency
  • List of prior treatments
  • Previous surgeries

Also, below are other travel -related links, including to the CDC travel website which makes recommendations based on travel destination along with underlying problems.

A summary of the ICN travel tips from the PAC PowerPoint Presentation:

 

 

Fluid Management for Abdominal Surgery

Posted on by

A recent study (PS Myles et al. NEJM 2018; 378: 2263-74, editorial 2335-6) throws some shade on the idea that restricting IV fluids during surgery results in better outcomes.

With ERAS (enhanced recovery after surgery) procedures, one of the components has been restricting IV fluids during surgery due to concerns that excessive fluid will result in bowel wall edema and slower recovery.  To better determine if a restrictive IV fluid approach or a more liberal approach was better, this RELIEF study randomized approximately 3000 patients who were receiving major abdominal surgery into two arms: a restrictive group and a  liberal group; they received a median of 3.7 liters of IV fluids and 6.1 liters respectively during and up to 24 hours after surgery.

Key findings:

  • Rate of disability-free survival at 1 year was 81.9% in the restrictive group and 82.3% in the liberal group (hazard ratio for death or disability was 1.05, CI 0.88-1.24, P=0.61)
  • Rate of acute kidney injury was 8.6% in the restrictive fluid group compared to 5.0% in the liberal fluid group (P<0.001). Renal replacement therapy was 0.9% in the restrictive fluid group compared to 0.3% in the liberal fluid group (P=0.048).
  • Rates of surgical site infection was 16.5% in the restrictive fluid group compared to 13.6% in the liberal fluid group (P=0.02).  The authors speculate that this could be related to perfusion of surgical anastomosis.

The associated commentary notes that in this age of minimally invasive surgery, a modestly liberal administration of IV fluids does not create substantial fluid retention.

My take: Restrictive fluid regimen during major abdominal surgery resulted in higher rates of kidney injury and surgical site infections.  This study indicates that for ‘enhanced recovery’ that a more liberal fluid regimen is safer.

Pediatric Intestinal Pseudo-obstruction: Consensus Recommendations

Posted on by

A new report from an ESPGHAN-Led Expert Group (N Thapar et al. JPGN 2018; 66: 9991-1019) provides detailed recommendations for pediatric intestinal pseudo-obstruction (PIPO).  In addition, this report serves as an excellent self-assessment of your vision.  If you can read figure 1, which has some incredibly tiny font size, then your vision is fantastic.

Full Link: “Paediatric Intestinal Pseudo-obstruction: Evidence and Consensus-based Recommendations From an ESPGHAN -Led Expert Group”

Aside from that snarky comment, the report offers a great deal of useful advice.

  • After obstruction has been excluded, the authors recommend that patients should undergo a basic laboratory evaluation (including CBC, CMP, ESR/CRP, Celiac serology, Cortisol, Thyroid testing, Metabolic tests [urine organic acids, ammonia, lactate]) and to consider more extensive evaluation.
  • If primary, rather than secondary, PIPO is suspected, the authors recommend neurogastroenterology evaluation.

Subsequently, the authors review management: potential medications (Table 6), enteral feeds, gastrostomy and ileostomy, and in more than 80% then need for parenteral nutrition. At the time of therapeutic procedures, it is recommended to obtain full-thickness biopsies to further characterize the PIPO.

Clinical features which distinguish pediatric chronic intestinal pseudo-obstruction (CIPO) from adult CIPO are listed in Table 2. These include the following:

  • Frequent urologic involvement in pediatric CIPO which is rare in adults with CIPO.
  • Dilated bowel loops are commonly absent (~40%) in pediatric CIPO in the neonatal period and universal in adult cases.
  • Unlike in adults, there is a high risk of colonic and small bowel volvulus in pediatric CIPO and malrotation is evident in ~30% of pediatric CIPO (rarely seen in adults).
  • Also, in pediatrics, fabricated cases are more commonly encountered.

Intestinal transplantation should be considered in patients with PIPO who develop life-threatening complications associated with TPN or poor quality of life/high morbidity.

Why Does this Patient Have Colitis?

Posted on by

Just in time for this year’s Peachtree Road Race…

A brief report (RS Robinson et al. Gastroenterol 2018; 154: 1582-83) presents a case of a 28 year old, who had been in training for a marathon, with mild iron deficiency anemia, lower abdominal pain, and bloody bowel movements. The CT scan and colonoscopy showed diffuse colonic/ileal inflammation; the histology showed mucosal necrosis, crypt atrophy and acute inflammation (see below).

Answer to title question: Runner’s Colitis.  The authors note that in some long-distance runners an ischemic colitis can develop in part due to rerouting of blood with prolonged exercise.  Dehydration may exacerbate poor perfusion.  The splenic flexure and the rectosigmoid junction are particularly susceptible due to the ‘watershed’ nature of their blood supply.

The majority of individuals recover fully from this insult, though the literature describes one individual who required a subtotal colectomy after perforation.

HCV Treatment and “MELD Purgatory”

Posted on by

A recent study (A Kwong et al. Liver Transplantation 2018; 24: 735-43) and associated editorial (P Martin, pg 727-8) highlight an unintended consequence of HCV therapeutic success –“MELD purgatory.”

The study notes that with the availability of more effective direct-acting antivirals for HCV, there has been a decrease in wait-list mortality and a decrease in disease severity.  This was determined by reviewing 3 timed cohorts (2004 n=2408, 2009 n=2402, and 2014 n=2817) from the Organ Procurement and Transplantation database.

  • For example, the 2014 had a 21% lower risk of wait-list death (HR 0.79) than the 2009 cohort.  This is in contrast to other (non-HCV) disease in which there was no change in mortality.
  • Also, the MELD rate of change was 2.35 per year for the 2009 cohort compared to 1.90 for the 2014 group.
  • In their discussion, the authors note that while patients with HCV can achieve a sustained virologic response, those with advanced liver disease still need liver transplantation.  In these patient, there is a much lower prospect of attaining a high enough MELD score to receive organ offers –“leaving them with persistent complications and a decreased quality of life.”  This situation has been termed “MELD purgatory.”

The editorial notes that in the five years since the introduction of sofosbuvir, HCV has been displaced as the single commonest indication for liver transplantation by nonalcoholic fatty liver disease.  These agents have led to a decrease in advance HCV-related liver disease.  In addition, in the past, HCV infection had near universal recurrence after transplantation and this is no longer the situation.

My take: Undeniably, the advent of DAA have made a huge dent in progressive HCV liver disease. However, those with advanced liver disease may be stuck in a purgatory between good health and poor quality of life even after clearance of HCV infection.

VICTORY Consortium Showing Good Results for Vedolizumab

Posted on by

A presentation at the 13th Congress of the European Crohn’s and Colitis Organization (ECCO, Feb 2018) indicated that Vedolizumab had similar effectiveness as anti-TNF agents for both ulcerative colitis and Crohn’s disease. This data has been presented at a recent meeting in our office, some of the GI news magazines, and also ImproveCareNow listserv.

From Takeda website: Entyvio® (vedolizumab) Shows Higher Rates of Mucosal Healing Versus TNFα-Antagonist Therapy in Ulcerative Colitis and Crohn’s Disease Patients in Comparative Effectiveness Real-World Data Analysis

These analyses observed that patients with UC treated with Entyvio compared to TNFα-antagonist therapy had statistically significant higher 12-month cumulative rates of mucosal healing (50% vs 42%, hazard ratio [HR] 1.73, 95% confidence interval [CI] 1.10‑2.73) and clinical remission (54% vs 37%; HR 1.54, 95% CI 1.08‑2.18), and numerically higher steroid-free clinical remission rates (49% vs 38%; HR 1.43, 95% CI 0.79‑2.60). In CD, results reported statistically significant higher 12-month cumulative rates of mucosal healing (50% vs 41%; HR 1.67, 95% CI 1.13‑2.47), and numerically higher rates of clinical remission (38% vs 34%; HR 1.27, 95% CI 0.91‑1.78) and steroid-free clinical remission (26% vs 18%; HR 1.75, 95% CI 0.90‑3.43) compared to TNFα-antagonist therapy. These analyses were conducted by the VICTORY (Vedolizumab Health OuTComes in InflammatORY Bowel Diseases) Consortium.

My take: While the data compare anti-TNFs to vedolizumab in a “real-world setting,” the reported outcomes for anti-TNFs are lower than in other studies.  Vedolizumab had the best results in those with colonic disease.  Patients with Crohn’s disease with isolated small bowel disease had lower response rates.

Related study: AK Waljee et al Inflamm Bowel Dis 2018; 24: 1185-95. Using phase 3 clinical trial data with 594 subjects, the authors note that the majority of patients who will respond to vedolizumab can be identified by week 6 using a laboratory algorithm based on hemoglobin, albumin, vedolizumab level and CRP. Fformula: Hgb*Albumin*VDZ level/CRP*Weight. A cutoff of 185.96 predicted success with an AuROC of 0.75.   Higher hemoglobin, higher albumin, and higher vedolizumab level, and lower CRP are associate with higher response rates.
