Hospitalizations for Constipation Increasing in Cost and Frequency

New data shows that hospitalizations for constipation are increasing in frequency, and the associated costs are rising. Researchers analyzed the National Inpatient Sample Database for hospital discharge codes related to constipation, from 1997- 2010. This database contains records for over 7 million hospital visits per year.

From 1997 to 2010, discharges with a principal diagnosis of constipation increased by 128.6%. The average hospital charges for these patients increased 239.3% ($8,869 in 1997, adjusted for inflation, to $17,518 in 2010), although the average length of hospital stay only increased from 3.0 to 3.1 days in the same time.

The researchers speculate that the increase in hospitalizations for constipation may be due to the increasing use of medications that cause constipation, and that the cost increase is likely due to the increased number of diagnostic tests performed to test colon function. They conclude that constipation is an escalating burden on the health care system and recommend studies on preventative measures that could reduce this.

New Treatment for IBS with Diarrhea Available for Men in Japan

Ramosetron hydrochloride (HCl) tablets have been approved in Japan for treating IBS-D in males. The drug will be available under the brand name Irribow OD.

Ramosetron HCl is a serotonin 5-HT3 receptor antagonist. It acts on 5-HT3 receptors in the gut to slow intestinal transit and can also reduce transmission of intestinal pain. It is currently only approved for use in select countries including Japan and India, but is under investigation in several other countries.

Positive Phase 3 Trial Results of Eluxadoline in Patients with IBS-D

Two Phase 3 clinical trials evaluating eluxadoline in the treatment of diarrheapredominant irritable bowel syndrome (IBS-D) have shown that the medication helps improve both stool consistency and abdominal pain.

The manufacturer, Furiex Pharmaceuticals, is hoping to file a New Drug Application with the FDA sometime in mid 2014. Eluxadoline has been granted Fast Track status by the FDA, a process designed to facilitate development and expedite the review of drugs to treat diseases with significant unmet medical need.

Study Reports on Metaclopramide Nasal Spray Treatment for Gastroparesis

A Phase 2b study of a new method for treating nausea and vomiting in diabetic gastroparesis seems to show benefit over a traditional form of the treatment.

The study looked at the efficacy and safety of metoclopramide as taken by a new nasalspray delivery method versus by the usual oral tablets.

Delayed gastric emptying symptoms, which are typical of gastroparesis, can interfere with the absorption and efficacy of oral medications. A nasal spray is absorbed through the nasal membrane bypassing the gastric emptying. A Phase 3 study to further investigate the potential of this form of treatment is upcoming.

Probiotic Treatment for IBS Available Over the Counter in Ireland

An over the counter probiotic treatment for IBS is now available in Ireland. The active probiotic culture, Bifidobacterium infantis 35624, was originally discovered at the University College Cork, Ireland in the late 1990s. Since then, it has undergone clinical trials which have validated its efficacy in treating IBS symptoms. This probiotic has already been approved for over the counter use in the US and Canada under the brand name Align, and will be sold under the brand name Alflorex in Ireland.

New Type of Fiber to be Tested in Treating IBS Symptoms

Scientists from two universities are collaborating to develop and test a new type of fiber that may be useful in treating IBS.

The fiber was designed to reduce bloating, a common side effect of current fiber therapies for IBS. It was also designed to break down into a product which helps promote healthy intestinal flora, and to deliver these nutrients farther into the large intestine. Most fibers are broken down in the stomach and small intestine.

The National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) has awarded these researchers a grant to conduct a two-year clinical trial which will test the new fiber. The trial will be starting in early 2014.

FDA Offers New Online Reporting Method for Dietary Supplements

U.S. Food and Drug Administration (FDA) is now accepting online submission of adverse event reports related to the use of dietary supplements. Both mandatory and voluntary adverse event reports may be submitted online.

Reporting of dietary supplement adverse events is important in protecting consumers’ health and safety. The FDA routinely monitors the marketplace. However, with more than 85,000 dietary supplements on the market and no product specific registration requirement, adverse event reporting is invaluable in identifying harmful products.

Social Security Announces New Compassionate Allowances Conditions

The Social Security Administration (SSA) announced early this year that they have added 25 new Compassionate Allowances conditions, including chronic intestinal pseudo-obstruction (CIP).

CIP is a rare disorder of gastrointestinal motility where coordinated contractions (peristalsis) in the intestinal tract become altered and inefficient. When this happens, nutritional requirements cannot be adequately met. Pseudo-obstruction in children is usually congenital, or present at birth. It may also be acquired, such as after an illness.

Ondansetron May Ease IBS-D Symptoms

A new study from Garsed and colleagues in the UK suggests that the prescription drug ondansetron (Zofran, Zuplenz) may relieve some of the symptoms of diarrheapredominant IBS (IBS-D). Ondansetron has been in use for many years to decrease nausea and vomiting related to chemotherapy.

In the study, ondansetron was most useful to improve frequent loose stools and urgency in people with mild to moderate symptoms. No significant improvement was seen in abdominal pain. Reportedly, any benefit is usually seen within a few days.

The study was published in the journal Gut in December and is available online at

Comprehensive Nonsurgical Treatment Helps Women with Pelvic Floor Dysfunction

Many women suffer from pelvic floor dysfunction (PFD), which can cause a range of symptoms that include bladder and bowel problems, such as constipation or incontinence, as well as pelvic pain.

A retrospective study from the University of Missouri concluded comprehensive pelvic floor rehabilitation, which may include exercises to strengthen or relax the pelvic muscles, biofeedback therapy, constipation management, medications, incontinence devices, and behavioral modification, can help provide relief without surgery.

Existing records from nearly 800 women who had undergone therapy were examined. Those who completed at least five comprehensive rehabilitation sessions reported an average of 80% improvement in urinary incontinence, bowel dysfunction, and pelvic pain. Women who have symptoms of pelvic floor dysfunction are encouraged to discuss their concerns and treatment options with their health care providers.

New Use for Imaging Technique in Treatment of IBS

Researchers at the University of Nottingham, including IFFGD Advisory Board member Robin Spiller, M.D., are studying how Magnetic Resonance Imaging (MRI) can be used to study IBS.

In three new studies, Dr. Spiller and colleagues have used MRIs to study the volume of the colon and how it expands to make space for a meal; the transit time of a meal through the bowel; and how certain food triggers such as fructans and glucose act differently in different parts of the colon.

Their findings will help show how the bowel functions differently between healthy individuals and those with IBS. "In future," says Dr. Spiller, "We will be able to use our MRI techniques to test specific foods to understand how they will affect IBS."

FDA Issues Warning to Consumers on Certain OTC Laxatives

The Food and Drug Administration (FDA) recently issued a warning to consumers that some of the over-the-counter (OTC) laxatives – those called sodium phosphate laxatives – are potentially dangerous if dosing instructions or warnings on the Drug Facts label are not properly followed or when there are certain coexisting health conditions.

The label of sodium phosphate laxatives states that they should be used as one dose per day for no more than three days. If you do not have a bowel movement after taking a dose, you should not take another dose of the product.

FDA is now warning that adults older than 55, and adults and children with certain health conditions or who are using certain other medications – including ibuprofen – should ask their doctor before using these products because they may be at increased risk for harmful side effects. These new warnings are not currently in the Drug Facts label and apply to both adults and children. Read the full FDA update at ConsumerUpdates/ucm379440.htm.

NIDDK Staff Contributes to Revision of Dietary Guidelines for Americans

Starting this year, researchers and federal staff with diverse expertise, including many with ties to the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK), have embarked on an endeavor aimed at improving nutrition for all: Updating the Dietary Guidelines for Americans for 2015.

"The Guidelines provide practical, sciencebased advice to help Americans make food and physical activity choices that promote good health, a healthy weight and disease prevention for those ages 2 years and older," said Dr. Van S. Hubbard, director of the NIH Division of Nutrition Research Coordination (DNRC), housed within NIDDK.

"FODMAP Friendly" Food Certification Now Available in Australia

Food products that are low in FODMAPs (which stands for Fermentable Oligosaccharides, Disaccharides, Monosaccharides and Polyols) can now display a certification that identifies them as such in Australia.

The FODMAP Friendly logo was developed by Advanced Accredited Practicing Dietitian Dr. Sue Shepherd and is the first Australian Government-approved labeling system for fructose-friendly and lactose-friendly foods.

FODMAPs are a collection of sugars and related molecules that are found naturally in foods, and can often trigger symptoms of irritable bowel syndrome (IBS).

IBS Patients’ Self-Health Ratings Look Beyond GI Symptom Severity

People with IBS tend to base self-ratings of health by including other factors in addition to their IBS symptoms, a recent study suggests. The study looked at a sample of people with moderate to severe IBS, in order to understand how they rate their own health. The resulting self-ratings were correlated more with physical, psychological, and social issues rather than just with their IBS symptom severity. Worse perceptions of health included more severe non-digestive symptoms (such as fatigue), greater psychological distress, and more stressful life circumstances. This finding suggests that improving treatments for IBS requires addressing more than just IBS symptom severity in order to increase an individual’s overall perception of health.
