So wait, the US may have found a cure to Ebola? And if they have, will they come help patients of this dreaded disease in Africa? The article below was written by Dr. Sanjay Gupta for CNN
and they are saying an experimental drug called ZMapp likely saved the lives of 2 US missionary doctors (pictured above) who contracted the disease while working in Liberia…see report below from CNN..
Three vials containing an experimental drug stored at subzero temperatures were flown into Liberia last week in a last-ditch effort to save two American missionary workers who had contracted Ebola, according to a source familiar with details of the treatment.
The drug appears to have worked, sources say. Dr. Kent Brantly’s and Nancy Writebol’s conditions significantly improved after receiving the medication, sources say. Brantly was able to walk into Emory University Hospital in Atlanta after being evacuated to the United States last week, and Writebol is expected to arrive in Atlanta on Tuesday.
On July 22, Brantly woke up feeling feverish. Fearing the worst, Brantly immediately isolated himself. Writebol’s symptoms started three days later. A rapid field blood test confirmed the infection in both of them after they had become ill with fever, vomiting and diarrhea.
It’s believed both Brantly and Writebol, who worked with the aid organization Samaritan’s Purse, contracted Ebola from another health care worker at their hospital in Liberia, although the official Centers for Disease Control and Prevention case investigation has yet to be released.
A representative from the National Institutes of Health contacted Samaritan’s Purse in Liberia and offered the experimental treatment, known as ZMapp, for the two patients, according to the source.
The drug was developed by the biotech firm Mapp Biopharmaceutical Inc., which is based in San Diego. The patients were told that this treatment had never been tried before in a human being but had shown promise in small experiments with monkeys.
According to company documents, four monkeys infected with Ebola survived after being given the therapy within 24 hours after infection. Two of four other monkeys that started therapy within 48 hours after infection also survived. One monkey that was not treated died within five days of exposure to the virus.
Brantly and Writebol were aware of the risk of taking a new, little understood treatment and gave informed consent, according to two sources familiar with the care of the missionary workers. In the monkeys, the experimental serum had been given within 48 hours of infection. Brantly didn’t receive it until he’d been sick for nine days.
The medicine is a three-mouse monoclonal antibody, meaning that mice were exposed to fragments of the Ebola virus and then the antibodies generated within the mice’s blood were harvested to create the medicine. It works by preventing the virus from entering and infecting new cells.
The Ebola virus causes viral hemorrhagic fever, which refers to a group of viruses that affect multiple organ systems in the body and are often accompanied by bleeding.
Early symptoms include sudden onset of fever, weakness, muscle pain, headaches and a sore throat. They later progress to vomiting, diarrhea, impaired kidney and liver function — and sometimes internal and external bleeding.
The ZMapp vials reached the hospital in Liberia where Brantly and Writebol were being treated Thursday morning. Doctors were instructed to allow the serum to thaw naturally without any additional heat. It was expected that it would be eight to 10 hours before the medicine could be given, according to a source familiar with the process.
