About gutsandgrowth

I am a pediatric gastroenterologist at GI Care for Kids (previously called CCDHC) in Atlanta, Georgia. The goal of my blog is to share some of my reading in my field more broadly. In addition, I wanted to provide my voice to a wide range of topics that often have inaccurate or incomplete information. Before starting this blog in 2011, I would tear out articles from journals and/or keep notes in a palm pilot. This blog helps provide an updated source of information that is easy to access and search, along with links to useful multimedia sources. I was born and raised in Chattanooga. After graduating from the University of Virginia, I attended Baylor College of Medicine. I completed residency and fellowship training at the University of Cincinnati at the Children’s Hospital Medical Center. I received funding from the National Institutes of Health for molecular biology research of the gastrointestinal tract. I have authored numerous publications/presentations including original research, case reports, review articles, and textbook chapters on various pediatric gastrointestinal problems. Currently, I am the vice chair of the section of nutrition for the Georgia Chapter of the American Academy of Pediatrics. In addition, I am an adjunct Associate Clinical Professor of Pediatrics at Emory University School of Medicine. Other society memberships have included the American Academy of Pediatrics, the Food Allergy Network, the American Gastroenterology Association, the American Association for the Study of Liver Diseases, and the Crohn’s and Colitis Foundation. As part of a national pediatric GI organization called NASPGHAN (and its affiliated website GIKids) I have helped develop educational materials on a wide-range of gastrointestinal and liver diseases which are used across the country. Also, I have been an invited speaker for national campaigns to improve the evaluation and treatment of gastroesophageal reflux disease, celiac disease, eosinophilic esophagitis, and inflammatory bowel disease (IBD). Some information on these topics has been posted at my work website, www.gicareforkids.com, which has links to multiple other useful resources. I am fortunate to work at GI Care For Kids. Our group has 15 physicians with a wide range of subspecialization, including liver diseases, feeding disorders, eosinophilic diseases, inflammatory bowel disease, cystic fibrosis, DiGeorge/22q, celiac disease, and motility disorders. Many of our physicians are recognized nationally for their achievements. For many families, more practical matters include the following: – 14 office/satellite locations – physicians who speak Spanish – cutting edge research – on-site nutritionists – on-site psychology support for abdominal pain and feeding disorders – participation in ImproveCareNow – office endoscopy suite (lower costs and easier scheduling) – office infusion center (lower costs and easier for families) – easy access to nursing advice (each physician has at least one nurse) I am married and have two sons. I like to read, walk/hike, exercise, swim, and play tennis with my free time as well as go to baseball games. I do not have any financial relationships with pharmaceutical companies or other financial relationships to disclose. I have participated in industry-sponsored research studies.

FDA ‘Safety Initiative’ Now Means an Ounce of Ethanol Costs $30,000

Ethanol locks are now going to be ridiculously expensive (possibly $30,000 per month -for 1 oz) due to an FDA initiative which aims to improve drug safety. Paradoxically, this could endanger the health of many vulnerable children.

Modern Healthcare: Unapproved Drug Initiative adds up to $30 billion in healthcare costs Thanks to Jennifer Sterner-Allison for this reference.

An excerpt:

A regulatory pathway that aims to ensure drug safety is inflating healthcare spending by billions of dollars, according to a new report.

Four widely used drugs funneled through the Unapproved Drug Initiative will increase spending by more than $20.25 billion over a five-year span as manufacturers hiked prices between 525% to 1,644%…

“Hospitals are absorbing additional cost for drugs that are not innovative, not curing new diseases, do not have overwhelming R&D investment, and are often the preferred drug of choice.”…

The 2006 Unapproved Drug Initiative requires manufacturers to pull these drugs and prove to the FDA that they are safe. Typically, fewer manufacturers remain in the market after the FDA intervenes, which allows price manipulation.

Drugs that go through the UDI pathway can earn the manufacturer up to seven years of patent protection, which can prevent competition. At minimum, other suppliers of the drug targeted by the UDI also have to leave the market and receive approval, which can reduce competition.

The situation with ethanol is particularly egregious, said Erin Fox, a drug shortage expert and senior director of drug information and support services at University of Utah Health.

Belcher Pharmaceuticals is charging $1,000 per milliliter, which equates to $30,000 for one shot of ethanol, since it received an orphan drug designation through the UDI, granting Belcher’s drug exclusivity through 2025, she said. Belcher won the orphan drug classification, a status for drugs that treat rare diseases, for its treatment of hypertrophic obstructive cardiomyopathy.

“It is the perfect example of how this FDA approval process is broken,” Fox said. “Pediatric hospitals are going to be particularly impacted because ethanol is sometimes used to ‘lock’ IV ports to prevent infections in high-risk patients.”..

“FDA’s Unapproved Drug Initiative continues to have serious unintended consequences and in my opinion should be halted,” she said

My take: I have contacted the American Academy of Pediatrics and asked them to try to work on this problem.  The high cost of ethanol may prevent its routine use and result in central line infections, hospitalizations and even death in vulnerable children.

Ethanol locks can minimize infections among patients who receive intravenous nutrition (“TPN”) which was popularized by Dr. Dudrick.  Due to the exorbitant costs of ethanol, this may lead to increased infections, hospitalizations and even death.

 

Lifesaving APPs (Advanced Practice Providers)

A recent study (EB Tapper et al. Hepatology 2020; 71: 225-34, editorial 11-13) shows that advanced practice providers (APPs) provide care that translates into better outcomes for adults with cirrhosis.  APPs include physician assistants and nurse practitioners.

In a retrospective analysis (2001-15) of the Optum Clinformatics database (private insurance) with 389,257 adult patients, the authors show that patients who had an APP involved in their care had better outcomes.

Key findings among patients with APP care (with and without specialist involvement):

  • Reduced risk of death, aHR 0.43
  • Improved metrics: higher HCC screening aOR 1.23, higher variceal screening OR 1.20, increased use of rifaximin after discharge for HE OR 2.09, and reduced risk of hospital 30-day readmission OR 0.68.
  • Overall, AAP care alone was inferior to specialist care alone for all metrics except 30-day readmissions; however, shared care (APP and specialist care) was more successful than specialist care alone (eg. 30-day readmissions OR 0.91 with shared care)
  • APP involvement was associated with an almost 2-fold increase in costs per person per year (~$9600 compared to $4500) and increased procedures
  • Due to the retrospective nature, it is unclear how many of the APPs had specialty training; as such, it is not clear whether primary care APP involvement is equivalent to specialty care APP involvement

My take: Based on my experience, this study likely could be replicated in most medical fields.  APPS improve patient outcomes.

What to Expect After Pediatric Liver Transplantation: Cognitive Function and Quality of Life

A recent study (D Ohnemus et al. Liver Transplantation 2020; 26: 45-56, editorial 9-11) examined health-related quality of life (HRQOL) and cognitive functioning approximately 15 years after liver transplantation (LT).

Study details:

Median age 16 years.  Original group was a SPLIT research cohort recruited from 20 centers and then tested at multiple time points; for this study, 8 sites of the original 20 were included.  It is noted that patients with serious neurologic injury were excluded. Among an initial group of 108, there were 79 available for potential enrollment.  In this group, 65 parent surveys were completed and 61 child surveys.

Key findings:

  • For cognitive and school functioning, 60% and 51% of parents reported “poor” functioning, respectively (>1 SD below the health mean).  41% of children rated their cognitive function as poor.
  • Adolescents’ self-reported overall HRQOL was similar to that of healthy children; in contrast, parents rated their teenage children as having significantly worse HRQOL than healthy children in all domains.
  • The cognitive score in the poor functioning group at the latest time point was lower than at first time point measurement (ages 5-6 years and at least 2 years after LT), “suggesting that difficulties intensified in adolescence for those who have problems in early childhood.”
  • Almost half had received special educational services.

The editorial notes that the PedsQL Cognitive Functioning Scale scores used by the investigators were considered subjective.  “The more objective PedsPCF scores fell within the normal range.”

My take: This report indicates that a majority of children are likely to have some cognitive deficits and many are likely to have reduced HRQOL following liver transplantation; in addition, if these problems are detected at a younger age, they are likely to persist.

Useful Data on Cholangitis Following Kasai Portoenterostomy

A recent retrospective study (SH Baek et al. JPGN 2020; 70: 171-77) provide useful information on cholangitis following a Kasai portoenterostomy in patients (n=160) with biliary atresia (BA).

Key points:

  • 126 of 160 (79%) had at least one episode of cholangitis during the study period (2006-2015).  Median followup was 49 months in those who had cholangitis compared to 33 months for those who did not develop cholangitis.
  • Age at time of Kasai: 63 days in those with cholangitis and 55 days in those without (P=0.42)
  • 76% of patients had recurrent cholangitis
  • Yield from blood culture was 9%.  In those with culture-proven cholangitis, Enterococcus faecium was most common pathogen (28%), followed by E. coli (15%), Enterobacter cloacae (11%), and Klebsiella pneumoniae (9%)
  • In their institution, there was a fairly-low susceptibility of gram-negative bacteria to cefotaxime (8/21, 38%). Almost all gram-negative isolates were susceptible to meropenem.
  • In their institution, there was fairly-low susceptibility of gram-positive organisms to ampicillin (8/19, 42%) and 100% susceptibility to vancomycin.
  • The authors noted that their empiric choice for treatment had been cefotaxime but this has now been reviewed; and a newer regimen, “a frequent alternative,” is the use of vancomycin along with an aminoglycoside.

It is worth noting that Up-to-Date has several recommended regimens for acute cholangitis (in adults).  For lower-risk infections, the authors recommend either a single agent like piperacillin-tazobactam or dual therapy with specific cephalosporins (eg. cefotaxime, ceftriaxone) and metronidazole.  For higher-risk infections, the Up-to-Date recommendations include meropenem or piperacillin-tazobactam as single agents or one of two cephalosporins (cefepime or ceftazidime) along with metronidazole.

My take: Cholangitis is common after biliary atresia.  Familiarity with changing susceptibility, particularly local patterns, will help optimize outcomes.

“Weekend Effect” and Pediatric IBD

The “weekend effect” is a term used to indicate that outcomes for many medical conditions are worse when patients are admitted to the hospital on the weekend.

A recent study (MD Egberg et al. Inflamm Bowel Dis 2020; 26: 254-60; editorial by C Ballengee Menchini 261-2) documents the degree of this effect on the risk of complications for pediatric patients with inflammatory bowel disease (IBD).

This study used a cross-sectional analysis with the Kids’ Inpatient Database (KID), a nationally representative database.  The study included 3255 urgent surgical hospitalizations and included patients 18 years old and younger.

Key findings:

  • The risk difference for weekend Crohn’s disease (CD) surgical hospitalizations involving a complication vs weekday hospitalizations was 4%
  • The risk difference for weekend ulcerative colitis (UC) surgical hospitalizations involving a complication vs weekday hospitalizations was 7%
  • The relative risk of surgical complications was 30% and 70% higher for weekend admissions for CD and UC respectively
  • For both weekend and weekday admissions, the most common complications were ‘postoperative intestinal/hepatic complications,’ ileus and sepsis
  • Hospital teaching status and population-density did not affect outcomes

Possible Reasons for Weekend Effect:

  • Reduced hospital staffing
  • Delayed seeking care by patients which increases illness severity
  • Reduced access to diagnostic resources
  • Lack (or reduced) of access to specialist care

Limitations include reliance on administrative data and potential for misclassification and unidentified confounding variables.
