In late July, when it looked like Dr. Kent Brantly wasn t going to make it, a small news item escaped Liberia. It spoke of Brantly s treatment not of the Ebola vaccine, Zmapp, which Brantly later got. But of a blood transfusion. He had received a unit of blood from a 14-year-old boy who had survived Ebola because of Dr. Brantly s care, the missive said. Now months later, Brantly, who has since recovered from his battle with the virus, has passed on the favor. A 26-year-old Dallas nurse named Nina Pham, who contracted the illness while treating the United State s first Ebola patient, has received Brantly s blood. It s not the first time it has been used to treat Ebola patients. Recovered Ebola victim Richard Sacra got it, as well as U.S. journalist Ashoka Mukpo, who last night said he s on the mend. Injecting the blood of a patient like Brantly, who has recovered from Ebola and developed certain antibodies, is a decades-old, but promising method of treatment that, academics and health officials agree, could be one of the best means to fight Ebola. Called a convalescent serum, it might also save Pham, an alum of Texas Christian University.
Convalescent serum is high on our list of potential therapies and has been used in other outbreaks, a WHO spokesperson told Science in August. There is a long history of its use, so 1 / 8is there 3 / 8 lots of experience of what needs to be done, what norms and standards need to be met.
The treatment, in fact, is nearly as old as the disease itself. Peter Piot of the London School of Hygiene and Tropical Medicine, who discovered Ebola in 1976 in Zaire, said the idea even back then was promising. We had only one possible treatment option in the form of serum from convalescents who had very high levels of antibodies, he explained to Science. The blood was later used to treat a researcher in the United Kingdom who infected himself while drawing blood from an Ebola-infected guinea pig. He survived. But there are some problems with the treatment. One is the transfer of blood. Even when regulated and monitored, there is risk of spreading other diseases, specifically HIV or hepatitis C. Another issue is uncertainty over the treatment s efficacy. Scientists haven t determined a definitive, causal link between recovery and the serum. Then there s problems with the sample size. Despite the virulence of this current bout, Ebola outbreaks are a relatively uncommon thing. They erupt, then disappear. And that s partly why, scientist Heinrich Feldmann told Newsweek, it has often been too difficult expand the sample size. That, however, hasn t stopped researchers from wondering. In 1999, the Journal of Infectious Diseases published an article that analyzed the success of blood transfusions on several patients infected with Ebola during a 1996 outbreak in Kikwit, Congo. The findings suggested something pivotal. Only one of the eight patients died. All were seriously ill with severe asthenia, four presented with hemorrhagic manifestations, and two became comatose as their disease progressed, the study stated. Only one patient (12.5 percent) died; this number is significantly lower than the overall case fatality case (80 percent) for the Ebola outbreak in Kikwit and than the rates for other Ebola epidemics. One of the patients described in the study was very similar to Nina Pham. She was 27-year-old Italian nurse. She had used protective clothing but had perhaps touched her eyes accidentally while wearing contaminated gloves.

This is something that would be ready near term.
And hopefully it s something that can save the life of Nina Pham.Related Articles:
