IBS is managed effectively with the right drugs, for the right symptoms

New American Gastroenterological Association guidelines provide guidance on treatments

2014-11-05
(Press-News.org) Bethesda, MD (Nov. 5, 2014) — Up to 15 percent of the general adult population is affected by irritable bowel syndrome (IBS), and most patients struggle to find effective drug therapy. A new guideline from the American Gastroenterological Association (AGA) provides these patients and their physician's guidance. The new guideline and accompanying technical review have been published in Gastroenterology, the official journal of the AGA Institute.

"Because no IBS therapy is uniformly effective, many patients describe a history of a variety of treatments alone or in combination. This guideline will help patients and physicians navigate the drug options. It's also important to consider other clinically relevant information, such as a patient's values and preferences, when making treatment decisions," said Shahnaz Sultan, MD, MHSc, an author of the guidelines, from the gastroenterology section, Department of Veteran Affairs Medical Center, North Florida/South Georgia Veterans Health System.

The AGA developed the guideline using Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology2 and best practices as outlined by the Institute of Medicine. Despite a large number of published studies on IBS therapies, in most cases, the quality of available data and or the balance of risks and benefits for a particular therapy did not overwhelmingly support the use of particular drugs. Additionally, there are no studies comparing the effectiveness of commonly used drugs to each other nor is there data comparing combinations of therapies to placebo or to each other.

Recognizing these limitations, the AGA Institute guidelines represent a rigorous, evidenced-based summary of extensive literature describing the use of drug treatments for IBS.

Patients with IBS-C (constipation) Recommends using linaclotide (over no drug treatment) in patients with IBS-C. (Strong recommendation; High-quality evidence)

Suggests using lubiprostone (over no drug treatment) in patients with IBS-C. (Conditional recommendation; Moderate-quality evidence)

Suggests using lubiprostone (over no drug treatment) in patients with IBS-C. (Conditional recommendation; Moderate-quality evidence)

Patients with IBS-D (diarrhea) Suggests using rifaximin (over no drug treatment) in patients with IBS–D. (Conditional recommendation; Moderate-quality evidence)

Suggests using alosetron (over no drug treatment) in patients with IBS-D to improve global symptoms. (Conditional recommendation; Moderate evidence)

Suggests using loperamide (over no drug treatment) in patients with IBS-D. (Conditional recommendation; Very low-quality evidence)

Patients with IBS Suggests using tricyclic antidepressants (over no drug treatment) in patients with IBS. (Conditional recommendation; Low-quality evidence) Suggests against using selective serotonin reuptake inhibitors for patients with IBS. (Conditional recommendation; Low-quality evidence) Suggests using antispasmodics (over no drug treatment) in patients with IBS. (Conditional recommendation; Low-quality evidence)

What sounds counter-intuitive to an activity commonly perceived as quiet is the broad recommendation of scientists at Michigan State University (MSU) recommending that small-scale fishing in the world's freshwater bodies must have a higher profile to best protect global food security. In this month's journal Global Food Security, scientists note that competition for freshwater is ratcheting up all over the world for municipal use, hydropower, industry, commercial development, and irrigation. Rivers are being dammed and rerouted, lakes and wetlands are being drained, fish ...

CNIO researchers create a mouse model that reproduces noonan syndrome
2014-11-05
Noonan syndrome is a rare disease that is characterised by a set of pathologies, including heart, facial and skeletal alterations, pulmonary stenosis, short stature, and a greater incidence of haematological problems (mainly juvenile myeloid leukaemia, or childhood leukaemia). There is an estimated incidence of 1 case for every 1,000–2,500 births, and calculations show some 20,000–40,000 people suffer from the disease in Spain. From a genetic point of view, this syndrome is associated to mutations in 11 different genes —the K-Ras gene among them— ...

Trial results reveal first targeted treatment to boost survival for esophageal cancer

2014-11-05
PATIENTS with a specific type of oesophageal cancer survived longer when they were given the latest lung cancer drug, according to trial results being presented at the National Cancer Research Institute (NCRI) Cancer Conference today (Wednesday). Up to one in six patients with oesophageal cancer were found to have EGFR duplication in their tumour cells and taking the drug gefitinib, which targets this fault, boosted their survival by up to six months, and sometimes beyond. This is the first treatment for advanced oesophageal cancer shown to improve survival in patients ...

Researchers engineer a smart bomb to attack childhood leukemia
2014-11-05
Fatih Uckun, Jianjun Cheng and their colleagues have taken the first steps towards developing a so-called "smart bomb" to attack the most common and deadly form of childhood cancer — called B-lineage acute lymphoblastic leukemia (ALL). In a November study in the new peer-reviewed, open-access journal EBioMedicine, they describe how this approach could eventually prove lifesaving for children who have relapsed after initial chemotherapy and face a less than 20 percent chance of long-term survival. "We knew that we could kill chemotherapy-resistant leukemia cells ...

How important is long-distance travel in the spread of epidemics?

How important is long-distance travel in the spread of epidemics?
2014-11-05
The current Ebola outbreak shows how quickly diseases can spread with global jet travel. Yet, knowing how to predict the spread of these epidemics is still uncertain, because the complicated models used are not fully understood, says a University of California, Berkeley biophysicist. Using a very simple model of disease spread, Oskar Hallatschek, assistant professor of physics, proved that one common assumption is actually wrong. Most models have taken for granted that if disease vectors, such as humans, have any chance of "jumping" outside the initial outbreak area ...

Study shows benefits of being fat (but not too fat) for deep-diving elephant seals

Study shows benefits of being fat (but not too fat) for deep-diving elephant seals
2014-11-05
Researchers using a new type of tracking device on female elephant seals have discovered that adding body fat helps the seals dive more efficiently by changing their buoyancy. The study, published November 5 in the Proceedings of the Royal Society B, looked at the swimming efficiency of elephant seals during their feeding dives and how that changed in the course of months-long migrations at sea as the seals put on more fat. The results showed that when elephant seals are neutrally buoyant--meaning they don't float up or sink down in the water--they spend less energy ...

The findings are online ahead of print in the Journal of Adolescent Health. Participants, ...

Blocking mitochondrial fission: An effective treatment for Parkinson's disease?

2014-11-05
A study led by a researcher from Plymouth University in the UK, has discovered that the inhibition of a particular mitochondrial fission protein could hold the key to potential treatment for Parkinson's Disease (PD). The findings of the research are published today, 5th November 2014, in Nature Communications. PD is a progressive neurological condition that affects movement. At present there is no cure and little understanding of why some people get the condition. In the UK one on 500 people, around 127,000, have PD. The debilitating movement symptoms of the disease ...

Cost and effect: Cheaper remedies should rule for diabetes nerve pain, U-M experts say

2014-11-05
ANN ARBOR, Mich. — Millions of people with diabetes take medicine to ease the shooting, burning nerve pain that their disease can cause. And new research suggests that no matter which medicine their doctor prescribes, they'll get relief. But some of those medicines cost nearly 10 times as much as others, apparently with no major differences in how well they ease pain, say a pair of University of Michigan Medical School experts in a new commentary in the Annals of Internal Medicine. That makes cost -- not effect -- a crucial factor in deciding which medicine ...
