Lower GI problems plague many with rheumatoid arthritis

04.04.2012
Add lower gastrointestinal (GI) problems such as ulcers, bleeding and perforations to the list of serious complications facing many rheumatoid arthritis patients.

They are at greater risk for GI problems and gastrointestinal-related death than people without the disease, a Mayo Clinic study shows. Researchers say their findings point out the need for new ways to prevent and treat lower GI disease in rheumatoid arthritis patients; the incidence of lower gastrointestinal complications is rising even as upper GI problems decrease significantly among rheumatoid arthritis patients.

Smoking, the use of steroids known as glucocorticoids, prior upper GI disease and abdominal surgery were associated with lower GI problems in rheumatoid arthritis patients, the study found. The research was published online this week in The Journal of Rheumatology.

Rheumatologists have long recognized that rheumatoid arthritis patients are at higher risk for upper GI problems such as stomach ulcers and bleeding. The study suggests increased awareness of that and likely, modern treatment strategies that emphasize the need to prevent ulcers and bleeding and control rheumatoid arthritis without relying as much on nonsteroidal drugs and corticosteroids have reduced upper GI complications, says co-author Eric Matteson, M.D., Chair of the Department of Rheumatology at Mayo Clinic in Rochester.

"What we are also seeing for the first time in a systematic way is that patients with rheumatoid arthritis also are at risk for problems of bleeding and ulcers in the lower gut, especially the colon," Dr. Matteson says.

Lung disease, heart problems, osteoporosis and carpal tunnel syndrome are among other potential complications for patients with rheumatoid arthritis, an often debilitating disorder in which the immune system attacks tissues, inflaming joints. To study the incidence of GI problems in rheumatoid arthritis patients, Mayo researchers identified 813 patients with rheumatoid arthritis and 813 without it, using data from 1980-2008 in the Rochester Epidemiology Project, a National Institutes of Health-supported effort in which Mayo and other Olmsted County, Minn., health care providers pool medical records.

The incidence of upper GI problems in rheumatoid arthritis patients declined over the years but was still higher in that group: 2.9 for every 100 person years compared with 1.7 in non-rheumatoid arthritis patients. The rate of lower GI problems in rheumatoid arthritis patients was 2.1, compared with 1.4 in others, the study found. Of the arthritis patients studied, 229 died. GI problems were significantly associated with their deaths, including bleeds, perforations and obstructions.

"Our findings emphasize that physicians and patients must be vigilant for these complications, which can occur without causing abdominal pain," Dr. Matteson says. "Especially stopping smoking and reducing the use of corticosteroids would appear to be important in reducing the risk of major lower GI complications."

The study co-authors are biostatistician Cynthia Crowson; gastroenterologist Nicholas Talley, M.D., Ph.D.; and Elena Myasoedova, M.D., Ph.D., all of Mayo Clinic.

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...

Im Focus: Optoelectronic Inline Measurement – Accurate to the Nanometer

Germany counts high-precision manufacturing processes among its advantages as a location. It’s not just the aerospace and automotive industries that require almost waste-free, high-precision manufacturing to provide an efficient way of testing the shape and orientation tolerances of products. Since current inline measurement technology not yet provides the required accuracy, the Fraunhofer Institute for Laser Technology ILT is collaborating with four renowned industry partners in the INSPIRE project to develop inline sensors with a new accuracy class. Funded by the German Federal Ministry of Education and Research (BMBF), the project is scheduled to run until the end of 2019.
