Uranium exposure linked to increased lupus rate

14.11.2012
People living near a former uranium ore processing facility in Ohio are experiencing a higher than average rate of lupus, according a new study conducted by scientists at the University of Cincinnati and Cincinnati Children's Hospital Medical Center.

Lupus is a chronic inflammatory disease that can affect the skin, joints, kidneys, lungs, nervous system and other organs of the body. The underlying causes of lupus are unknown, but it is usually more common in women of child-bearing age.

For this new study, a collaborative team of UC and Cincinnati Children's researchers wanted to compare lupus rates between people who were exposed to uranium and those who were not in an effort to explain the high number of lupus cases reported in a Cincinnati community.

Extensive review of medical records and serum antibody analysis to verify the cases, concluded that people who were exposed to higher levels of uranium, based on their living proximity to a former uranium ore processing plant, had lupus rates four times higher than the average population.

"Former studies have suggested that people with lupus may be more sensitive to radiation and that both genetics and environmental exposures play a role in disease development. Our study shows a strong correlation between uranium exposure, a radioactive substance, and an increased lupus rate that merits further investigation," says Pai-Yue Lu, MD, a pediatric rheumatology fellow at Cincinnati Children's and lead researcher for the study.

"With more research in this area, we may gain additional insight on the types of environmental factors that contribute to lupus development and the mechanisms by which they work," Lu adds. "There could be other effects of uranium and related exposures that could contribute to or help explain our findings."

Lu is presenting this finding and its potential implication at the American College of Rheumatology Annual Scientific Meeting Monday, Nov. 12, in Washington, D.C. She completed the project as part of her master's degree in clinical and translational science training at UC.

The Cincinnati-based team's research is based on nearly two decades of data collected through the Fernald Medical Monitoring Program, the United States' first and largest legally mandated comprehensive medical monitoring program. The program was established in 1990 after a federal investigation revealed that National Lead of Ohio's Feed Materials Production Center in the Hamilton County, Ohio, community of Fernald, was emitting dangerous levels of uranium dust and gases into the surrounding communities.

"The availability of this cohort and carefully collected data and biospecimens provides a great setting to ask research questions," says Susan Pinney, PhD, UC professor of environmental health and principal investigator of the Fernald study.

Almost 10,000 community residents enrolled in the Fernald Medical Monitoring Program. Community residents were classified into several exposure groups: high exposure, moderate exposure, low exposure and no exposure. (Uranium plant workers were not part of this study.)

"Typical U.S. incidence rates for lupus are 1.8 to 7.6 cases per 100,000. Among the 25 confirmed lupus cases we identified through the Fernald community cohort, 12 were in the high exposure group, eight with moderate exposure and five in the low exposure group," says Lu.

Research was supported by a pilot grant from a Center for Environmental Genetics, a National Institute of Environmental Health Sciences-funded program to support core facilities and technologies needed to conduct innovative research that focuses on how environmental agents interact with genetic and epigenetic factors to influence disease risk and outcome. Shuk-mei Ho, PhD, Jacob A. Schmidlapp Chair and Professor of Environmental Health, serves as principal investigator of the CEG grant.

Im Focus: Einblicke unter die Oberfläche des Mars

Die Region erstreckt sich über gut 1000 Kilometer entlang des Äquators des Mars. Sie heißt Medusae Fossae Formation und über ihren Ursprung ist bislang wenig bekannt. Der Geologe Prof. Dr. Angelo Pio Rossi von der Jacobs University hat gemeinsam mit Dr. Roberto Orosei vom Nationalen Italienischen Institut für Astrophysik in Bologna und weiteren Wissenschaftlern einen Teilbereich dieses Gebietes, genannt Lucus Planum, näher unter die Lupe genommen – mithilfe von Radarfernerkundung.

Wie bei einem Röntgenbild dringen die Strahlen einige Kilometer tief in die Oberfläche des Planeten ein und liefern Informationen über die Struktur, die...

Im Focus: Molekulares Lego

Sie können ihre Farbe wechseln, ihren Spin verändern oder von fest zu flüssig wechseln: Eine bestimmte Klasse von Polymeren besitzt faszinierende Eigenschaften. Wie sie das schaffen, haben Forscher der Uni Würzburg untersucht.

Bei dieser Arbeit handele es sich um ein „Hot Paper“, das interessante und wichtige Aspekte einer neuen Polymerklasse behandelt, die aufgrund ihrer Vielfalt an...

Im Focus: Das Universum in einem Kristall

Dresdener Forscher haben in Zusammenarbeit mit einem internationalen Forscherteam einen unerwarteten experimentellen Zugang zu einem Problem der Allgemeinen Realitätstheorie gefunden. Im Fachmagazin Nature berichten sie, dass es ihnen in neuartigen Materialien und mit Hilfe von thermoelektrischen Messungen gelungen ist, die Schwerkraft-Quantenanomalie nachzuweisen. Erstmals konnten so Quantenanomalien in simulierten Schwerfeldern an einem realen Kristall untersucht werden.

In der Physik spielen Messgrößen wie Energie, Impuls oder elektrische Ladung, welche ihre Erscheinungsform zwar ändern können, aber niemals verloren gehen oder...

Im Focus: Manipulation des Elektronenspins ohne Informationsverlust

Physiker haben eine neue Technik entwickelt, um auf einem Chip den Elektronenspin mit elektrischen Spannungen zu steuern. Mit der neu entwickelten Methode kann der Zerfall des Spins unterdrückt, die enthaltene Information erhalten und über vergleichsweise grosse Distanzen übermittelt werden. Das zeigt ein Team des Departement Physik der Universität Basel und des Swiss Nanoscience Instituts in einer Veröffentlichung in Physical Review X.

Seit einigen Jahren wird weltweit untersucht, wie sich der Spin des Elektrons zur Speicherung und Übertragung von Information nutzen lässt. Der Spin jedes...

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
