Chicken Pox Virus May Be Linked to Serious Condition in the Elderly

19.02.2015

A new study links the virus that causes chicken pox and shingles to a condition that inflames blood vessels on the temples and scalp in the elderly, called giant cell arteritis. The study is published in the February 18, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology. The condition can cause sudden blindness or stroke and can be life-threatening.

The varicella zoster virus, of the herpes virus family, can cause chicken pox and may reactivate later in life in the form of shingles, a very painful rash.

“Our analysis, which is the largest to-date, provides compelling evidence that the virus also reactivates in people over 60 in another way, triggering giant cell arteritis,” said study author Don Gilden, MD, Professor of Neurology at the University of Colorado School of Medicine in Denver and a Fellow of the American Academy of Neurology.

Giant cell arteritis causes swelling and tenderness of the arteries on the scalp and temples of people over the age of 50. Gilden noted that it is the most common type of inflammation of blood vessels in the elderly, affecting an estimated 29 out of 100,000 people. Symptoms include a new severe headache, scalp tenderness, jaw discomfort, blurred vision, fever, weight loss and tiredness. Importantly, the cause of this condition has been uncertain, prompting the present study.

For the study, researchers searched for evidence of the virus in 13 temporal artery biopsies of people who died and had no previous symptoms of giant cell arteritis and in 84 temporal artery biopsies of people with giant cell arteritis. All of the biopsies were from people over the age of 50.

The virus was found in 74 percent of the biopsies with giant cell arteritis and in only 8 percent of the normal skin biopsies.

“If the association can be replicated in other studies, clinical trials should focus on treating people with giant cell arteritis with a combination of the current steroid drugs used for the condition, plus anti-viral treatment for the virus,” said Gilden.

The study was supported by the National Institutes of Health.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

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...
