New study sheds light on the importance of supportive care for Ebola patients

                                                                     Nov. 6, 2014

...a WHO-coordinated retrospective study, published in the New England Journal of Medicine, provides evidence that supportive care, especially rehydration and correction of metabolic abnormalities, may contribute to patient survival.

The study analysed clinical data on 37 confirmed Ebola patients admitted for treatment at hospitals in Conakry, Guinea’s capital and most densely populated city.

The cases occurred during the first month of West Africa’s first outbreak of Ebola virus disease. Fourteen of the patients were heath care workers. The majority (12) acquired their infection in a health care setting.

The majority (65%) of patients were male, countering assumptions that women, who are more likely to provide home care for patients and prepare bodies for funerals and burials, are more frequently exposed and infected.

To replace fluids lost through severe diarrhoea, 36 patients (97%) received oral rehydration solution. Additional intravenous fluid resuscitation was given to 28 (76%) patients.

Experimental Ebola drugs should not be withheld, WHO says

World Health Organisation doubts feasibility of placebo-controlled trials in west Africa, but FDA favours ‘gold standard’

Scientists involved in trials of experimental drug treatments for the Ebola epidemic in west Africa should not be compelled to withhold them from some patients, says the World Health Organisation, despite objections from the US that it is the only way to be sure they work.

UT nasal spray vaccine for Ebola effective in monkeys

By Todd Ackerman                                                                           Nov. 5, 2014

... researchers at the University of Texas-Austin have developed a nasal spray vaccine that has protected monkeys against the deadly Ebola virus even a year after immunization.

The vaccine, a genetically engineered cold virus containing a tiny portion of Ebola DNA, saved 100 percent of monkeys who got a single spray through the nose in a new UT study. Injecting the vaccine only saved the lives of about 50 percent.

 
 
 Maria Croyle, a professor of pharmaceutics and the study's principal investigator, said an inhaled Ebola vaccine is more attractive because it would be cheaper and safer than needle-delivered vaccines.

"The main advantage is the long-lasting protection after a single inhaled dose," Maria Croyle, a  professor of pharmaceutics and the study's principal investigator, said in a statement. "This is important since the longevity of other vaccines for Ebola (hasn't been) fully evaluated....

U.S. Ebola researchers plead for access to virus samples

reuters.com - November 5th 2014 - Julie Steenhuysen

Scientists across the United States say they cannot obtain samples of Ebola, complicating efforts to understand how the virus is mutating and develop new drugs, vaccines and diagnostics.

The problems reflect growing caution by regulators and transport companies about handling Ebola as well as the limited resources of West African countries which are struggling to help thousands of infected citizens.

Ten scientists from eight major research institutions contacted by Reuters reported they were unable to get Ebola samples in recent months.

Canada contributes more money, but no medical workers in Ebola fight

TORONTO GLOBE AND MAIL                               Nov. 3, 2014
By Kelly Grant
Canada is spending another $30.5-million to fight Ebola, but Ottawa is still not answering pleas from international aid organizations for medical personnel to care for the ill in West Africa.

The bulk of the money announced on Monday – $23.5-million – will be spent on testing a Canadian vaccine and an experimental therapy, ZMapp, both of which were developed largely at the National Microbiology Lab in Winnipeg....

Canada has so far dispatched two mobile laboratories with rotating teams of scientists to rapidly diagnose or rule out Ebola in Sierra Leone.

But Ottawa has been reluctant to send medical staff to West Africa because the government cannot guarantee they could be airlifted out if they fall ill.

New England researchers help shape the fight on Ebola

THE BOSTON GLOBE                                  Nov. 3, 2014

By Carolyn Y. Johnson

Northeastern University researchers use computers to simulate 20 million virtual Ebola outbreaks each week. Yale scientists are building three models that project the spread of the deadly disease. And a team at Boston Children’s Hospital is combing through data to gauge whether medical interventions are working.

....  they are providing a constant stream of evidence that is beginning to reveal the weak spots of the epidemic. For example, scientists’ models are beginning to identify basic patterns of who is being infected and when and how Ebola is being spread, which could help identify the most meaningful ways to intervene.

...According to their model, isolating three-quarters of the patients within the first four days that they show symptoms would help eliminate the disease.

Researchers Study Ebola Link to Gene in Rare Disease

WALL STREET JOURNAL                             Nov 3, 2014

By Amy Dockser Marcus

In the search for answers about Ebola, researchers are starting to look at an unexpected group of people: parents of children who have the rare but fatal genetic disease Niemann-Pick Type C.

Blood and tissue samples from Hugh and Chris Hempel of Reno, Nev., whose children have a rare disease, may help in ongoing Ebola research. Hempel family

The intersection between research in Ebola and NPC disease was surprising, and came after two scientific papers were published in 2011 demonstrating that a protein made by the same gene related to NPC disease is essential for Ebola infection.

Ebola uses the so-called NPC1 protein made by the gene to get into the cell and replicate the virus.

Now, research suggests that the gene that causes NPC disease may also offer protection against Ebola.

Ebola-carrying bats may be heroes as well as villains

REUTERS                                                                                  NOV. 2, 014

By Ben Hirschler

LONDON - Bats are living up to their frightening reputation in the world's worst Ebola outbreak as prime suspects for spreading the deadly virus to humans, but scientists believe they may also shed valuable light on fighting infection.

Bats can carry more than 100 different viruses, including Ebola, rabies and severe acute respiratory syndrome (SARS), without becoming sick themselves.

While that makes them a fearsome reservoir of disease, especially in the forests of Africa where they migrate vast distances, it also opens the intriguing possibility that scientists might learn their trick in keeping killers like Ebola at bay.

What We Don’t Know About Ebola

Overview of what still needs to be learned about the Ebola virus

Research studies have suggested at least three potential paths through which the Ebola virus can invade tissues. Credit Photograph by the C.D.C. via Getty Images

THE NEW YORKER                                      Nov. 1, 2014

By

...there are still serious gaps in what we know about the biology of Ebola, and that ignorance inhibits us from preventing future outbreaks and reducing death rates that still exceed seventy per cent. We don’t know enough about the biology of Ebola to bring the outbreak under full control, or to neutralize the virus once the outbreak is contained. Between on-the-ground efforts and advances in science, we need a balanced approach.

The Ebola questions

Scientists know a lot about the virus that causes Ebola — but there are many puzzles that they have yet to solve.

NATURE SCIENCE International Weekly Journal of Science                                   Oct. 29, 2014

By Erika Check Hayden

Scientists know a lot about the virus that causes Ebola — but there are many puzzles that they have yet to solve.

An Ebola virus particle from the 2014 outbreak.

To much of the world, the virus behind the devastating Ebola outbreak in Africa seems to have stormed out of nowhere. But Leslie Lobel thinks we should have seen it coming.

In 2012, Lobel and a team of researchers spent six months in Uganda studying the Ebola virus and related viruses. Over the course of their stay, these pathogens caused at least four separate outbreaks of disease in central Africa, affecting more than 100 people. To Lobel, a virologist at Ben-Gurion University of the Negev in Beer-Sheva, Israel, the outbreaks felt like the small tremors that can precede a major earthquake. “We all said, something is going on here; something big is going to happen,” he says.
