UC Davis Children's Hospital patient becomes third person in U.S. to survive rabies
(SACRAMENTO, Calif.) — Precious Reynolds, an 8-year-old resident of rural Humboldt County, has become the third person in the United States known to have recovered from rabies infection without receiving the rabies vaccine, through the efforts of a team of dedicated physicians, nurses and therapists at UC Davis Children's Hospital.
The hospital team was led by Jean Wiedeman, associate professor of pediatric infectious diseases. Wiedeman coordinated Precious' care with state, local and federal officials at the U.S. Centers for Disease Control and Prevention (CDC), the California Department of Public Health's Encephalitis and Special Investigations Section, and county health departments in Humboldt and Sacramento counties.
"Precious received superb care from everyone at UC Davis Children's Hospital," Wiedeman said. "And we were enveloped with support from the CDC and the state encephalitis group from the moment we learned she was infected," Wiedeman said. She said the consultations with national, state and local public-health officials occurred as often as 20 times a day in the early phases of the patient's treatment.
"From the very beginning, Precious had a very rapid, robust immune response to her infection, which is a significant contributor to why she survived," Wiedeman said. "She is truly a fighter."
Rabies is a highly infectious viral disease of mammals that usually is transmitted through the bite or scratch of a rabid animal. Because pets and farm animals typically are inoculated against the disease, exposure commonly comes from a bat, skunk, fox or other wild animal.
While it is not known how she became infected, public health officials suspect Precious may have encountered a feral cat near her elementary school in the tiny town of Willow Creek, Calif., near the Humboldt County border with Trinity County, though the infected animal never was found.
Rabies infection in humans is exceptionally rare in the United States, Wiedeman said, with only two-to-nine cases reported each year. Many more people — some 30,000 annually — are exposed and receive post-exposure prophylaxis (PEP) to prevent disease.
Reynolds did not receive post-exposure prophylaxis, a series of antiviral inoculations administered following infection, because the date and nature of her exposure is not known. Rabies is virtually always fatal without PEP.
The virus affects the central nervous system, ultimately causing encephalitis, or acute inflammation of the brain, and eventually, death. Very early symptoms of rabies in people include fever, headache, and general weakness or discomfort. As the disease progresses, however, more specific symptoms appear.
That was the case with Reynolds, according to her grandmother, Shirley Roby.
"It started with a stomach ache," said Roby, who immediately took Precious to the family physician, who suggested she might have appendicitis and recommended she be seen at a local hospital. The hospital ruled out appendicitis and suggested she had a case of the flu.
But as the child's condition continued to decline, she became unable to swallow, and began to feel pain in her neck and back. Eventually she would lose muscle control and the ability to stand or walk. Roby returned Precious to the community hospital.
"This isn't the flu," she told them pointedly. "To me, it looked more like polio."
The hospital transferred the child by ambulance to McKinleyville, Calif., where she was flown to Sacramento and transported to UC Davis Children's Hospital. She was admitted through the pediatric emergency department to the pediatric intensive care unit (PICU).
There, Wiedeman and critical care medicine colleagues, including physicians Jennifer Plant, Theresa Murdock-Vlautin and Mac Wayment, among others, evaluated Precious and determined that she had encephalitis.
Wiedeman specializes in the treatment of children with infectious diseases. She has specific expertise in the management of complex clinical cases, especially those with problematic diagnostic and management intricacies. She provided samples of Precious' blood and spinal fluid to the state Encephalitis and Special Investigations Section of the California Department of Public Health, directed by Carol Glaser, a physician and veterinarian and associate professor of pediatric infectious diseases at UC San Francisco.
Test results returned on May 5 indicated that Precious had rabies. Wiedeman, along with the UC Davis pediatric critical care doctors, the CDC and state encephalitis group, decided to treat her with a therapy first used in Wisconsin in 2004 on a 15-year-old girl who contracted rabies from a bat bite. Her physician placed the girl in a drug-induced coma while administering antiviral medication. There has been one other survivor, a patient in Texas in 2009, who did not receive treatment with this approach.
"This was a unique experience," Wiedeman said. "It was reassuring that the CDC and the state encephalitis group had our back," Wiedeman said. But more difficult was sharing the diagnosis with Roby and Precious' father, Willie Reynolds.
"You're aware that the child has a minimal chance of survival, that the protocol has been applied worldwide in 25 cases with only four survivors. You're not going to the family with good news if you've got a diagnosis of rabies. It's heartbreaking," Wiedeman said.
"None of us thought she would leave the PICU. When she did it was unbelievable," said Krystle Realyvasquez, a nurse who cared for Precious when she was first admitted to the intensive care unit and then before she graduated to the step-down unit.
The protocol requires a team approach to the patient's care. Realyvasquez was among a handful of nurses who treated Precious during her intensive care unit stay. "Being in that team environment, where everybody knows what's going on day-by-day, makes for more uniform care, so that we were better able to provide for her needs," she said.
As time passed, however, Precious' immune response gave Wiedeman and the rest of her health-care team and family reason for hope.
"I was very encouraged that with her diagnosis she continued to interact," Wiedeman said. "She was right there until we deepened her coma significantly. She could respond to you and had brisk pupillary responses throughout the coma. There were subtle signs that she was performing well given her diagnosis."
"To me, the most remarkable and lasting part of this experience is that you had a previously, healthy, very vigorous spunky little girl, who got diagnosed with an almost universally fatal disease, and none the less a dedicated team of physicians and nurses — and her father and grandmother, who never left her bedside — pulled her through this," said Jennifer Plant, assistant clinical professor of pediatric critical care medicine, a key member of the team.
"In a year her grandmother is going to send me a video of her wrestling. I am exceptionally proud and happy."
Roby said that she never gave up on her granddaughter.
"At first my heart sank to my feet. But I guess doctors have to put on a suit of armor to tell parents the truth," Roby said. "I decided that we were just going to think positive."
Roby's instincts were right. She said that Precious received "excellent, excellent" care for two weeks in the pediatric intensive care unit and later in the general pediatric patient-care unit where she continues to receive treatment. The athletic little girl — a wrestler and rodeo sheep rider or "mutton buster" — is back on her feet and beginning to walk with the help of physical medicine and rehabilitation.
Roby said she that she is grateful to everyone who has cared for her granddaughter — particularly Wiedeman, for her devoted care for Precious.
"She fought for Precious tooth and nail," Roby said. "She is something special to me."
Wiedeman and Roby cautioned parents to admonish their children to avoid any and all contact with wild or feral animals — including dead ones — particularly bats. If exposed, Wiedeman said, rabies is completely preventable with a vaccine that is far more sophisticated than the multiple painful inoculations of the past.
"Talk to your kids about any kind of animal scratching or biting them. The shots don't hurt. They're a little expensive — but not half as expensive as having a loved one go through this."
