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.

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Hauchdünne magnetische Materialien für zukünftige Quantentechnologien entwickelt

Zweidimensionale magnetische Strukturen gelten als vielversprechendes Material für neuartige Datenspeicher, da sich die magnetischen Eigenschaften einzelner Molekülen untersuchen und verändern lassen. Forscher haben nun erstmals einen hauchdünnen Ferrimagneten hergestellt, bei dem sich Moleküle mit verschiedenen magnetischen Zentren auf einer Goldfläche selbst zu einem Schachbrettmuster anordnen. Dies berichten Wissenschaftler des Swiss Nanoscience Institutes der Universität Basel und des Paul Scherrer Institutes in der Wissenschaftszeitschrift «Nature Communications».

Ferrimagneten besitzen zwei magnetische Zentren, deren Magnetismus verschieden stark ist und in entgegengesetzte Richtungen zeigt. Zweidimensionale, quasi...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
