Two Studies: 1. COVID-19 Transmissibility 2.Fecal Microbiota Transplantation in 372 Children

A study in Nature suggests that more than 40% of SARS-CoV-2 infections (COVID-19 viral infections) are spread in the presymptomatic stage: Temporal dynamics in viral shedding andtransmissibility of COVID-19 (Thanks to Steven Liu for this reference).

An excerpt:
We report temporal patterns of viral shedding in 94 patients with laboratory-confirmed COVID-19 and modeled COVID-19 infectiousness profiles from a separate sample of 77 infector–infectee transmission pairs. We observed the highest viral load in throat swabs at the time of symptom onset, and inferred that infectiousness peaked on or before symptom onset. We estimated that 44% (95% confidence interval, 25–69%) of secondary cases were infected during the index cases’ presymptomatic stage, in settings with substantial household clustering, active case finding and quarantine outside the home. Disease control measures should be adjusted to account for probable substantial presymptomatic transmission.


A recent retrospective multi-center study (MR Nicholson et al. Clin Gastroenterol Hepatol 2020; 18: 612-9) provides data on fecal microbiota transplantation (FMT) for Clostridium difficile infection (CDI). Congratulations to one of my partners, Jeffery Lewis, who is one of the coauthors. This paper’s abstract is noted in a separate blog: Large Study Show FMT Efficacy/Safety in Children.

Though this is a pediatric study, the authors included patients up to 23 years.  335 of the patients had followup for at least 2 months following FMT.

Key findings:

  • 81% of patients had a successful outcome after a single FMT and 86.6% after single or repeated FMT
  • Higher success rates were associated with fresh donor stool (OR 2.66), FMT via colonoscopy (OR 2.41), and with not having a feeding tube (OR 2.08)
  • Though not reaching statistical significance, patients with inflammatory bowel disease had a high failure rate of 23% (26/111).  Short bowel syndrome patients had a 50% failure rate (5/10), solid organ transplant recipients had a 56% failure rate (5/9), and patients with feeding tubes had a 32% failure rate (21/65).
  • Seventeen patients (4.7%) had a severe adverse event during the 3-month follow-up period, including 10 hospitalizations; however, the majority were unrelated to FMT. Specific adverse reactions that were related or may have been included aspiration pneumonia on day of procedure (n=1), IBD flare/colectomy (n=5), and vomiting/dehydration (n=1)
  • Common adverse reactions included diarrhea, abdominal pain, and bloating. (These symptoms have been reported in up to 70% of adults following FMT.)

The authors note that a prior systematic review had indicated that delivery of FMT via colonoscopy was more successful in adults (95% vs 88%), though there are some additional risks with colonoscopy.

It is worth considering that the failure rate in some patients could be due to misdiagnosis, particularly in certain populations like patients with IBD and or organ transplant recipients.  In these populations, PCR assays may result in false-positive diagnosis and should be confirmed with an ELISA assay.   While eradication of CDI with FMT improves clinical symptoms and reduces the use of antibiotics the true benefit and risks will not be known for a long time.  Does FMT increase or reduce the risk of downstream infections, autoimmune disease, and metabolic syndrome?

My take: Many of the concerns with FMT can only be adequately addressed with prospective studies (with strict definitions of CDI) and longer followup.

COVID-19 Posts

My wife has been receiving a lot of compliments for her daily jokes which she decided to post for all of the neighborhood walkers. “A lot of people cry when they cut an onion. The trick is not to form an emotional bond.”

This coronavirus disease has caused incredible upheaval & misery throughout the world.  In addition, it has created an “infodemic.”  This blog post is intended to collate my previous related posts/& many of the referenced links into one location, to provide GI society guidelines for PPE/endoscopy as well as to place a good image at the bottom:

Aslo, recommendations from GI societies -AGA, ACG, ASGE and AASLD

  1. Use of Personal Protective Equipment in GI Endoscopy
  2. Endoscopic Procedure Guidance

Use of Personal Protective Equipment in GI Endoscopy
  1. General measures of physical distancing and adequate hand hygiene are of critical importance and need to be practiced diligently, independent of other protective measures.
  2. All elective, non-urgent procedures should be postponed until ample supplies of PPE, hospital beds and other resources are available after the COVID-19 surge.
  3. All members of the endoscopy team should wear a full set of PPE, predicated on resource availabilities.
  4. The correct sequence of putting on and taking off PPE (“donning” and “doffing”) is critical and needs to be understood and practiced [17].
  5. All members of the endoscopy team should wear N95 respirators (or devices with equivalent or higher filtration rates) for all GI procedures performed on patients with known SARS-CoV-2 infection and those with high risk of exposure. Given the high rate of infection transmission from pre-symptomatic individuals, all patients undergoing GI endoscopy in an area of community spread need to be considered ‘high risk’.
  6. All healthcare workers should have their N95 respirators fitted by an occupational health specialist prior to the first usage.
  7. Staffing of endoscopy rooms should be reduced to the minimum number of individuals necessary, in order to conserve PPE and other resources.
  8. In some cases, shortages may require extended and limited reuse of N95 respirators. Guidance is available on how to wear, remove and store respirators to minimize contamination [18]. Decontamination of N95 respirators with hydrogen peroxide vapor has been approved by the FDA as a means of reuse in times of limited supply [19].
Below is guidance regarding how to manage the clinical procedural needs of patients during the COVID-19 pandemic. Any decisions should be informed by the local situation and available resources. There may be state, local and institutional rules in place that must be considered as well. This guidance is offered until more definitive data-driven information becomes available.
For those patients for whom a procedure or appointment is not deemed immediately necessary, each practice should implement mechanisms to assure appropriate follow-up once the immediate impact of the COVID-19 pandemic has eased or passed.
All Elective Procedures Should Be Delayed
  1. Screening and surveillance colonoscopy in asymptomatic patients ​
  2. Screening and surveillance for upper GI diseases in asymptomatic patients​, including surveillance for esophageal varices in patients with cirrhosis
  3. For patients needing interval endoscopy for obliteration of esophageal varices post-acute bleeding, the individual circumstances of the patient need to be taken into account to determine safety of delay (i.e., size of varices, red wale markings, CTP status of the patient, acute bleed characteristics).
  4. Evaluation of non-urgent symptoms or disease states where procedure results will not imminently (within 4-6 weeks) change clinical management (e.g., EGD for non-alarm symptoms, EUS for intermediate risk pancreatic cysts) ​
  5. Motility procedures – esophageal manometry, ambulatory pH testing, wireless motility capsule testing and anorectal manometry
Urgent/Emergent Procedures Should Not Be Delayed ​
  1. Upper and lower GI bleeding​ or suspected bleeding leading to symptoms
  2. Dysphagia significantly impacting oral intake (including EGD for intolerance of secretions due to foreign body impaction or malignancy (stent placement))
  3. Cholangitis or impeding cholangitis (perform ERCP)​
  4. Symptomatic pancreaticobiliary disease ​(perform EUS drainage procedure if necessary for necrotizing pancreatitis and non-surgical cholecystitis, if patient fails antibiotics)
  5. Palliation of GI obstruction [UGI, LGI (including stent placement for large bowel obstruction) and pancreaticobiliary] ​
  6. Patients with a time-sensitive diagnosis (evaluation/surveillance/treatment of premalignant or malignant conditions, staging malignancy prior to chemotherapy or surgery) ​
  7. Cases where endoscopic procedure will urgently change management (e.g., IBD)
  8. Exceptional cases will require evaluation and approval by local leadership on a case by case basis
Q. Should all emergent EGD patients be intubated?
A. Absent other reasons that present a threat to the airway, intubation is not indicated for all EGDs. Proper use of PPE, including N95 masks is paramount.
Q. Should procedures be performed on patients with intermediate level cases such as Iron Deficiency Anemia (IDA) or mild dysphagia?
A. Decisions regarding cases such as these will need to be made on a case by case basis, taking into account resource availability, level of community infectivity and risk to the patient.


FMT Warning & “Get Your Butt in Gear” –Less Than 10% of Kids Meeting Guidelines for Healthy Movement

To lessen obesity, three health risk behaviors have been targeted:

  • Sedentary behavior -goal is to limit to 2 hours of screen time in 24 hours
  • Physical activity -goal is 1 hour (or more) of moderate to vigorous activity
  • Sleep duration -goal is 9-12 hours (ages 6-12 years) and 8-10 hours (13-18 years)

A recent study (X Zhu et al. J Pediatr 2020; 218: 204-9) shows that <10% of U.S. kids meet these goals.  The authors examined data (2016-17) from the National Survey of Children’s Health (NSCH) dataset (n=71,811)

Key findings:

  • 80.9% did NOT meet physical activity goal
  • 76.2% did meet screen time goal
  • 581% did meet sleep goal
  • However, only 9.4% met all 3 goals
  • Not meeting these ‘movement’ guidelines was associated with obesity, particularly in females (aOR 4.97 compared to aOR 3.99 for males)

My take: We are all made to be different shapes and sizes.  Nevertheless, we should strive for healthy behaviors and healthy eating which could improve outcomes.

Bill Gates: What We Need to Do Now for COVID-19, False-negative testing & Article Describing 3 Stages of Infection

A recent commentary in Washington Post by Bill Gates states clearly what we need to do now to improve the outcome of this pandemic. Link (may be behind paywall) : Bill Gates: Here’s how to make up for lost time on covid-19

  1. Nationwide stay-at-home.  Given mobility in country, having some states policies lessens the effectiveness of individual state mandates. “Because people can travel freely across state lines, so can the virus. The country’s leaders need to be clear: Shutdown anywhere means shutdown everywhere. Until the case numbers start to go down across America — which could take 10 weeks or more — no one can continue business as usual or relax the shutdown. Any confusion about this point will only extend the economic pain, raise the odds that the virus will return, and cause more deaths.”
  2. Much more testing and quicker turnaround.  This would allow more effective isolation policies and help determine if/when we are truly making progress.
  3. Nationwide coordination for ventilators/supplies.  Competition between states is counterproductive
  4. Preparation for making billions of doses of vaccine (when available)


From NY TimesIf You Have Coronavirus Symptoms, Assume You Have the Illness, Even if You Test Negative

An excerpt:

Current coronavirus tests may have a particularly high rate of missing infections. The good news is that the tests appear to be highly specific: If your test comes back positive, it is almost certain you have the infection… From a technical standpoint, under ideal conditions, these tests can detect small amounts of viral RNA.  In the real world, though, the experience can be quite different, and the virus can be missed.


Thanks to Ben Gold for the following article: COVD-19 Illness in Native and Immunosuppressed States: A Clinical-Therapeutic Staging Proposal (HK Siddiqi, MR Mehra. J Heart Lung Transplantation) available at

This article describes three stages of COVID-19 and associated laboratory/clinical findings.

  1. I -Early stage.  “In patients who can keep the virus limited to this stage of COVID-19, prognosis and recovery is excellent”
  2. II-Pulmonary involvement (IIa) without and (IIlb) with hypoxia
  3. III-Systemic Hyperinflattion

And a reason to wary of hydroxychloroquine in its use for COVID-19:


Liver Shorts March 2020 & COVID-19 Screenshots

Sofusbuvir and Ribavirin for children with hepatitis C infection (3-12 yrs, genotype 2 or 3) P Rosenthal et al. Hepatology 2020; 71: 31-43. n=54.  SVR12 was 98% (one patient did not complete treatment).

Alpha-one antitrypsin heterozygositiy contributes to cirrhosis in fatty liver disease. Liver Transplantation 2020; 26: 17-24. From the discussion: “unexpected PASD+ globules, in the context of advanced liver disease, are a specific finding that indicates the presence of a mutant A1AT allele.”  Of 196 explanted livers from NASH patients, 21 (11%) has PASD+ globules; however, among NASH patients the frequency was 47%.  Also, the Z allele was present in 10% of all tested liver explants, this exceeds the 2% rate in the general population.  Thus, in agreement with other studies, A1AT heterozygosity contributes to chronic liver failure, but may affect fatty liver disease more than other chronic liver diseases.

Durability of HBsAg Loss in Hepatitis B AS Alawad et al. Clin Gastroenterol Hepatol 2020;18: 700-09.  In this retorspective study form NIH, 89/787 HBsAg-positive patients cleared HBsA; 65 had confirmed clearance. (spontaneous in 19, post-interferon in 22, and post-NA treatment in 24). 62 of 65 remained negative after a mean time of 9.6 years. 3 patients had seroreversion at a mean of 20 months after stopping therapy, though this was transient in 2 of 3 and may have been a false-positive.

Are Medications Contributing to Obesity and Fatty Liver Disease? ~25% of U.S. adults take a prescription medication  that often produces obesity as an adverse effect. (Hales CM et al. Obesity Week 2019, Link to Abstract T-OR-2037). PRESCRIPTION MEDICATIONS THAT PROMOTE WEIGHT GAIN: Prevalence of Use Among U.S. Adults, 2013-2016 Common obesogenic medications in this cohort, (n=11,055), included all glucocorticoids, beta-blockers, and antihistamines and some agents among antidepressants, antipsychotics, antidiabetics and progestin-only contraceptives.  Medications were defined as promoting weight gain according to the Endocrine Society Clinical Practice Guideline for the Pharmacological Management of Obesity (J Clin Endocrinol Metab, 2015).

What is the Current Standard of Care for PPE and Endoscopy Cases?

CC Thompson et al. Gastointestinal Endoscopy (EPUB), in a letter to the editor, respond to two recent studies on SARS-CoV-2 virus/COVID-19 and provide recommendations for PPE use in this era of COVID-19.

Here’s a link to manuscript: COVID-19 in Endoscopy: Time to do more?

Key points:

  • Reduce non-urgent cases. “We have cut our daily endoscopy volume by over 80% and closed our ambulatory endoscopy practice.”
  • Increase the use of telemedicine. “At present, telemedicine or virtual visits make up 91% of our upcoming clinic appointments.”
  • Physical distancing as advocated recently by WHO throughout a patient’s time in the endoscopy unit is stressed in the papers, with a 6-foot minimum between individuals.
  • Suggests “the need for a separate toilet as part of the isolation to minimize spread of infection due to bioaerosols from the toilet plume”
  • Our hospital system has recently changed policy to mandate that all employees wear surgical masks at all times while in the hospital and attest to their wellness online before reporting to work.
  • We suggest labeling each computer so the same provider uses that computer and chair for the entire day, and separating by at least 6 feet.
  • All endoscopic procedures (upper endoscopy, colonoscopy, EUS, ERCP) are aerosol-generating, referencing studies that show contamination of the endoscopist’s face during routine procedures. This makes all endoscopic procedures high risk from an infectious standpoint, and appropriate PPE is
    recommended… It makes little sense for healthcare providers to perform
    aerosolizing procedures, with patients coughing or passing gas on them, while not wearing an N95 mask or better
  • “It is important to use full PPE for all endoscopic procedures while in a pandemic such as this especially in areas with community spread, because no one is truly low risk given our ongoing difficulties with testing.”
  • “The mask can be reused as long as it is functional, not soiled, and not used in a suspected or COVIDpositive patient. It is important to cover the N95 to prevent soiling.”
  • “A study from China showed that no medical staff working in high-risk departments who wore N95s and practiced strict hand hygiene regardless of patient’s infection status became infected.”
  • “Testing all patients before high-risk procedures such as endoscopy is likely the best approach; however, this will depend on significant expansion of testing capabilities. Hopefully, the development of point-of-care testing with rapid results and increasing testing availability will make this a reality soon”

My take (in part from authors): “We are living through an unprecedented time and are all trying our best to protect our patients and ourselves under suboptimal conditions of limited PPE, limited testing, and limited data. ”  The recommendations in this article are based mainly on expert opinion and may need modifications based on new data and circumstances.

COVID-19: Veneto vs. Lombary & Georgia’s Part of the Pandemic

Harvard Business Review: Lessons from Italy’s Response to Coronavirus

An excerpt:

While Lombardy and Veneto applied similar approaches to social distancing and retail closures, Veneto took a much more proactive tack towards the containment of the virus…

  • Extensive testing of symptomatic and asymptomatic cases early on.
  • Proactive tracing of potential positives. If someone tested positive, everyone in that patient’s home as well as their neighbors were tested. If testing kits were unavailable, they were self-quarantined.
  • A strong emphasis on home diagnosis and care. Whenever possible, samples were collected directly from a patient’s home and then processed in regional and local university labs.
  • Specific efforts to monitor and protect health care and other essential workers.

“The virus is faster than our bureaucracy.” ..Together, the need for immediate action and for massive mobilization imply that an effective response to this crisis will require a decision-making approach that is far from business as usual. If policymakers want to win the war against Covid-19, it is essential to adopt one that is systemic, prioritizes learning, and is able to quickly scale successful experiments and identify and shut down the ineffective ones. Yes, this a tall order — especially in the midst of such an enormous crisis

For those who live in Georgia, here’s a link to the official COVID-19 numbers from DPH:

  • Georgia DPH: COVID-19 Daily Status Report
  • It is worth noting that Georgia has a very high postive test rate (22%) compared to many states which likely indicates inadequate testing and a large number of undetected cases.

How to Do a Colonoscopic Polypectomy & U.S. COVID-19 Tracker

NPR’s website has a good tracker of what is going in each state.  Here’s the link:

NPR: Map: Tracking The Spread Of The Coronavirus In The U.S  One example: on this tracher, in Georgia, March 27, 8:30 am: 1642 reported cases, 56 deaths. (However, Georgia has conducted less than 10,000 tests in a population of more than 10 million).


A recent review (M Kay, R Wyllie. JPGN 2020; 70: 280-4) provides some practical tips for improving polypectomy technique.

Key points:

The optimal position for the polyp is in the 5-7 o’clock position.

  • Snaring juvenile polyps close to the head rather than close to the colonic wall “allows for easier therapeutic intervention if polypectomy bleeding occurs” (eg. hemoclip) and may lower the risk of complications like perforation
  • Epinephrine volume reduction (for larger polyps) (use 1:10,000 dilution) and saline-assisted polypectomy may facilitate procedure.  Large polyps (>2 cm) could require piecemeal resection; epinephrine reduction may result in a decreased size as well.
  • “Cold snare technique has replaced use of hot biopsy forceps in adults for removal of small sessile polyps”
  • Electrosurgical units (ESUs) -settings are specific to each unit.  Newer ‘smart’ ESUs have suggested default settings, typically lower settings for right colon. “Most endoscopists use pure coagulation current or a combination of coagulation and cutting settings (blended current) for snare polypectomy. Use of pure cutting current without coagulation will result in bleeding.”

Pipeline Medications for Ulcerative Colitis (Part 1) & Face Mask Shortages

Before getting to today’s post, I wanted to provide a link on why we are desperately short of face masks in the midst of this crisis: NY Times: How the World’s Richest Country Ran Out of a 75-Cent Face Mask

An excerpt:

The answer to why we’re running out of protective gear involves a very American set of capitalist pathologies — the rise and inevitable lure of low-cost overseas manufacturing, and a strategic failure, at the national level and in the health care industry, to consider seriously the cascading vulnerabilities that flowed from the incentives to reduce costs…

Given the vast global need for masks — in the United States alone, fighting the coronavirus will consume 3.5 billion face masks, according to an estimate by the Department of Health and Human Services — corporate generosity will fall short. People in the mask business say it will take a few months, at a minimum, to significantly expand production…

Hospitals began to run out of masks for the same reason that supermarkets ran out of toilet paper — because their “just-in-time” supply chains, which call for holding as little inventory as possible to meet demand, are built to optimize efficiency, not resiliency.

My take: Conserve, conserve, conserve PPE -supply chains meeting the need is NOT imminent.


Several articles from Gastroenterology highlight emerging medications for ulcerative colitis (UC).

Two of the studies:

  • WJ Sandborn et al. Gastroenterol 2020; 158: 550-61.
  • WJ Sandborn et al. Gastroenterol 2020; 158: 562-72.

The first study was a phase 2 randomized trial of etrasimod which is an oral selective sphingosine 1-phosphate receptor modulator.  A total of 156 patients were randomized into 3 groups: placebo, 1 mg etrasimod, and 2 mg etrasimod.

Key findings (graphical abstract):

In the second phase 3, double-blind, double-dummy study, Sandborn et al show that, after the initial 2 intravenous doses,  among patients with an initial response subcutaneous vedolizumab (108 mg every 2 weeks) had similar effectiveness to intravenous vedolizumab (300 mg every 8 weeks); both SC and IV vedolizumab resulted in higher clinical remission rates compared to placebo at 52 weeks in the 216 patients: 46.2%, 42.6%, and 14.3% respectively.

Iron Injectables

At bottom of post, more information on COVID-19.


At a recent Pharmacy, Nutrition, and Therapeutics (PNT) meeting, one of the topics that we reviewed was injectable iron agents, primarily iron sucrose (Venofer ®) and ferric carboxymaltose (Injectafer®).  Iron dextran is mainly used as a supplement in parenteral nutrition in our patient population.

Also, this topic is reviewed in Practical Gastroenterology Jan 2020 (M Auerbach et al. January 2020 • Volume XLIV, Issue 1: Treatment of Iron Deficiency in Gastroenterology: A New Paradigm

Key points:

  • Venofer® is much less expensive and currently has an FDA indication for children. To provide 1500 mg, Venofer®, 5 doses of 300 mg (~$75/dose)~$375. Injectafer®, 2 doses of 750 mg (~$600/dose) ~1200.  This does not include potential travel and other ancillary costs.
  • Dosing: Injectafer® can give large amounts of iron; in adults, typical dose is 750 mg given 7 days apart (in children 15 mg/kg/dose with 750 mg max).  FDA approved method is to administer over 15 minutes. Venofer® in children is 5-7 mg/kg/dose with 300 mg max per dose.
  • Injectafer® has been associated with hypophosphatemia (in 27%, <2 mg/dL); Hypophosphatemia has also been reported with iron sucrose.  The reported incidence of hypophosphatemia is higher with ferric carboxymaltose vs iron sucrose.
  • Other Adverse Effects
Iron Sucrose (Venofer®) Ferric Carboxy (Injectafer®)
Nausea 8.6% 7.2%
Vomiting 5% 1.7%
Diarrhea 7.2% <1%
Dizziness 6.5% 2%
Hypertension 6.5% 3.8%

Oral vs IV Iron for IBD: Auerbach et al recommends that “iron should only be given orally to IBD patients with inactive disease, mild anemia, and good tolerance of oral iron; in patients with active IBD oral iron should be avoided.”  They state that “oral iron has been shown to exacerbate intestinal inflammation of IBD independent of anemia, and cause luminal changes in microbiota and bacterial metabolism, which may negatively alter the microbiome.” (Has IV iron’s effect on the microbiome been studied/compared to oral iron?)

Safety of intravenous iron: “In a recent meta-analysis, the results of more than 10,000 patients who were treated with intravenous iron were reported. Compared to oral iron, placebo, and even intramuscular iron (which should never be given), while minor infusion reactions were observed with IV iron, there was no increase in serious adverse events compared to any comparator including placebo.”

My take: Injectafer® is likely preferable to Venofer® in the outpatient setting as adequate dosing can be given in 1 or 2 infusions.
