Evaluation of the Benefits and Risks of Introducing Ebola Community Care Centers, Sierra Leone

     

CDC                                                                                                         Dec. 23, 2014    

Abstract of study on usefulness of Ebola community care centers to supplement larger  Ebola treatment centers.

 In some parts of western Africa, Ebola treatment centers (ETCs) have reached capacity. Unless capacity is rapidly scaled up, the chance to avoid a generalized Ebola epidemic will soon diminish. The World Health Organization and partners are considering additional Ebola patient care options, including community care centers (CCCs), small, lightly staffed units that could be used to isolate patients outside the home and get them into care sooner than otherwise possible.

Using a transmission model, we evaluated the benefits and risks of introducing CCCs into Sierra Leone’s Western Area, where most ETCs are at capacity. We found that use of CCCs could lead to a decline in cases, even if virus transmission occurs between CCC patients and the community. However, to prevent CCC amplification of the epidemic, the risk of Ebola virus–negative persons being exposed to virus within CCCs would have to be offset by a reduction in community transmission resulting from CCC use.

Ebola raises profile of blood-based therapy

NATURE     by  Delcan Butler                                                                                        Dec. 23, 2014

With no drugs available to treat Ebola, eyes are turning to a therapy that had largely been relegated to the history books: transfusing patients with blood plasma donated by survivors, which contains antibodies against the virus.

Clinical trials of convalescent plasma therapy (CPT) have started in the past few weeks in Liberia, and are due to begin soon in Guinea and Sierra Leone. If the therapy saves lives, the approach could quickly be scaled up.

On the Front Lines of Ebola’s Most Pressing Mystery

WIRED     by   Erika Check Hayden                                                                              Dec. 23, 2014

KENEMA, Sierra Leone—Mohammed Sankoh Yillah, an outreach worker, spent days in the Ebola ward caring for his sister, nurse Mbalu Fonnie. After Fonnie died in July, Yillah tested positive for the virus. He was transported to another hospital for treatment, but asked to come back to Kenema to die.

But Yillah survived.

Today Yillah sits with four colleagues in an office, discussing a new research project. The study is collecting information about survivors like him. The hope is that the study might help explain why he and others beat Ebola, while their friends and colleagues—Alex, Mbalu—did not.

Epidemiologist Lina Moses runs the meeting. Her colleagues back at Tulane University, she says, hope to analyze blood samples from survivors; she collected 29 such samples here in November. “What they want to know in the laboratory,” she says, “is what kind of antibodies Mohammed Yillah has that helped him to survive Ebola.”

World Bank Supports The Gambia’s Ebola Prevention Plan

WORLD BANK PRESS RELEASE                                Dec. 22, 2014

The World Bank has approved a US$500,000 reallocation of existing development funds from on-going health and nutrition projects to support The Gambia prepare a plan in case of  a possible Ebola outbreak.

While there have been no reported cases of Ebola in The Gambia, its Ministry of Health and Social Welfare, working closely with the World Health Organization (WHO) and UNICEF, has nonetheless prepared a disease and Ebola preparedness plan.

 “The Ebola epidemic in neighboring countries has affected tourism in The Gambia as people are afraid to travel to and within Africa, resulting in great economic losses for the country,” said Vera Songwe, the World Bank Country Director for The Gambia. “We acknowledge that the virus is expanding both geographically and in the number of reported cases. The spread from Guinea to Mali highlights the escalating risk to regional security, stability and economic growth.

Tekmira Inks Deal to Test New Ebola Drug in Humans

GENOMEWEB                                                                                                                        Dec. 22, 2014
NEW YORK -- Tekmira Pharmaceuticals announced today that it has signed a deal that will support the clinical testing of its experimental Ebola therapy designed against the strain of the virus behind the outbreak in West Africa.

Tekmira has long been developing an siRNA-based Ebola drug called TKM-Ebola, but a Phase I study of that agent was suspended by US regulators until the company could provide additional safety data. Earlier this year, Tekmira management indicated that that trial might not restart as early as anticipated since the firm had begun focusing on a version specifically for the Guinea strain of the Ebola virus, which is driving the ongoing outbreak.

Tekmira said it has now inked a manufacturing and clinical trial agreement with the University of Oxford to provide the new drug, called TKM-Ebola-Guinea, for clinical trials in West Africa. The university is the representative of the International Severe Acute Respiratory and Emerging Infection Consortium, which will be testing TKM-Ebola-Guinea in infected individuals with funding from the Wellcome Trust.

Can the blood of Ebola survivors create a cure?

REUTERS       by  Julie Steenhuysen                                                                                 Dec. 22, 2014
CHICAGO --For months, Vanderbilt University researcher Dr. James Crowe has been desperately seeking access to the blood of U.S. Ebola survivors, hoping to extract the proteins that helped them overcome the deadly virus for use in new, potent drugs.

His efforts finally paid off in mid-November with a donation from Dr. Rick Sacra, a University of Massachusetts physician who contracted Ebola while working in Liberia. The donation puts Crowe at the forefront of a new model for fighting the virus...

In 2015, the three Ebola-affected countries will start offering cash payments for families hit by Ebola, as well as survivors having trouble re-acclimating to society out of stigma for the disease.

“We are seeing a backwards slide of development of about 10 years,” says Boaz Paldi, chief of media and advocacy at the United Nations Development Programme (UNDP). “The outlook is not good. We are fearful for these countries.”

The Ebola Treatment You Haven't Heard Of

FORBES       by David Kroll                                                                                              Dec. 19, 2014

Pharmaceuticals and biotechnology-derived products have attracted the greatest public and professional interest in treating victims of Ebola virus disease. But a privately-held, small company with a treatment for shock and multi-organ failure may be the dark horse victor in the race to stop the West African outbreak. LB1148 from San Diego-based Leading BioSciences is starting Phase 2 clinical trials that build on 12 years of NIH-funded research to address an underappreciated, common denominator in shock and organ failure, including shock caused by Ebola infection.

One More Drug For Ebola Treatment Pipeline?

NBC NEWS by Maggie Fox                                                                                                      Dec. 19, 2014

German doctors think they have another possible drug to add to the Ebola treatment pipeline. It's one already shown to be safe and in trials to treat heart attack victims.

The drug, called FX06, is made using a natural human blood-clotting protein called fibrin. The hope is it can help reduce the leaking of blood vessels that can seriously threaten people with advanced Ebola infections.

The team at Frankfurt University Hospital say it may have helped save a Ugandan doctor they treated, although they note it failed to save a second patient.

Nonetheless, it should be tested, they wrote in the Lancet medical journal.

"Even though the patient was critically ill, we were able to support him long enough for his body to start antibody production and for the virus to be cleared by his body's defenses," said Dr. Timo Wolf, who helped lead the research team. "FX06 could potentially be a valuable agent in contribution to supportive therapy."

Inside the cultural struggle to stamp out Ebola

A front-line report from Sierra Leone examines efforts to change hearts and minds in West Africa’s villages.

NATURE   by Erika Check Hayden                                                                             Dec. 17, 2014

Bombali District, Sierra Leone --Since September, the Ebola virus has stalked the villages and towns along the Kamakwie–Makeni Road, a rutted, red-dirt track that serves as the main artery for a string of villages in the western part of Sierra Leone’s Bombali District.

Yeli Sanda, a village just a few kilometres outside the district’s capital city of Makeni, was the first place to be hit. Over the following months, more than 40 people in the settlement of about 700 became infected; 22 died. In November, the virus infected a woman in Tambiama, about 11 km up the road. A friend who visited her acquired the virus and carried it another 1.5 km to the village of Mayata. She and at least five others there have died.
