Planning for bacteria in cancer patients may help hospitals fight infections

24.01.2013
What cancerous conditions lead to what kinds of bacterial infections? If doctors knew, they could predict which patients would likely benefit from pre-treatment with certain kinds of antibiotics.
A University of Colorado Cancer Center study published in this month’s issue of the International Journal of Infectious Diseases shows the answer: E. coli and Klebsiella pneumoniae are especially prevalent in patients with lung and GI cancers, more so for Klebsiella if these patients have been treated previously with aminopenicillins.

“These are really dangerous infections. You think about Klebsiella – it can develop resistance really quickly. And these patients have generally been in and out of hospitals. If you can’t treat the infection early, it can quickly become a serious and life threatening condition,” says Andrés Felipe Henao-Martínez, MD, clinical fellow in infectious diseases at the CU Cancer Center and University of Colorado Hospital.

His study looked at 462 patients with bacterial blood stream infections who were admitted to hospitals for treatment. Of these patients, 203 had cancer and 259 did not, allowing Henao-Martínez and colleagues to explore the clinical and microbiological differences between these populations. Interestingly, Henao-Martínez could show that most infections existing in cancer patients were acquired in hospital settings and not in the community, while non-cancer patients typically had community-acquired infections.

“Normally every hospital has a spreadsheet, an antibiogram, listing the bacteria and their rate of antibiotic resistance they’ve found in their patient population. But if you can predict ahead of time what bacteria you’re likely to encounter, you can prescribe more targeted antibiotic therapy before infections create complications,” Henao-Martínez says.

For example, previous treatment with aminopenicillins, like amoxicillin, and the presence of cancer seemed to significantly increase the likelihood of Klebsiella infection.

“Klebsiella pneumoniae is largely resistant to amoxicillin – with the immune system compromised by the cancer and by chemotherapy, and with other bacteria largely wiped away by the amoxicillin class of antibiotics it appears that Klebsiella is left to flourish with little competition in patients with cancer” Henao-Martínez says.

The group recently submitted a paper detailing genetic differences in outcomes in this population of bacterially infected patients admitted for treatment.

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...
