Abstract

BACKGROUND
Transfusion-transmitted babesiosis (TTB) has been rapidly increasing in incidence since the beginning of the 21st century. Asymptomatic individuals with Babesia infection are able to donate blood in the United States because of the lack of specific blood donation testing. Blood products collected in Babesia-endemic areas are distributed nationally; thus, clinicians in nonendemic states may fail to include babesiosis in the differential diagnosis of a patient who had a recent transfusion history and a fever of unknown origin.

STUDY DESIGN AND METHODS
We report the details of two cases of clinical transfusion-transmitted babesiosis and one asymptomatic infection identified in red blood cell recipients in two nonendemic states (South Carolina and Maryland), which, when combined with three recent additional cases in nonendemic states, totals six recipient infections in three nonendemic states.

RESULTS
Delayed diagnosis of transfusion-transmitted babesiosis places patients at risk for increased morbidity and mortality and may result in clinical mismanagement or unnecessary treatments. A peripheral blood smear should be reviewed in any patient with a recent transfusion and a fever of unknown origin. Prompt communication of the diagnosis among physicians is key to ensuring that patients with transfusion-transmitted babesiosis are treated expeditiously, and a transfusion service investigation is necessary to identify additional recipients from the same donor.

CONCLUSION
TTB is appearing in traditionally nonendemic states because of blood product distribution patterns. Clinicians should include TTB on the differential diagnosis in any patient presenting who had a recent transfusion history and a fever of unknown origin, regardless of where the transfusion took place.

Chronic Lyme Patients Bemoan Dearth of Local Doctors

Chronic Lyme patients bemoan dearth of local doctors

Twice a year, Joanne Creel of Yarmouth Port and her husband, Clarence Eckerson, make a pilgrimage to the Hyde Park, New York, office of Dr. Richard Horowitz to get treated for Lyme disease and co-infections.

It’s a long day, punctuated by coffee on the way there and and a stop at a diner for lunch on the five-hour drive back to the Cape.

“I’ve gone 14 years to New York,” putting the bill on credit cards since Horowitz does not take insurance, Creel said. She said she doesn’t have a choice.

Despite the prevalence of Lyme and other tick-borne disease on the Cape and Islands, no full-time medical specialist in Barnstable County treats Lyme disease patients with persisting symptoms that include cognitive deficits, swollen joints, vision problems and anxiety and depression.

“All of these patients are out there,” said Creel, a social worker and former marathon runner. “There is no doctor who is specifically for Lyme patients.”

But at a time when the U.S. Centers for Disease Control says there are 300,000 new cases of Lyme a year, advocates for people with the disease say they are dismayed at the lack of resources available to study the illness and at the paucity of physicians who are willing to treat patients with lingering symptoms, a problem exacerbated by the fact most treatments for lasting symptoms consist of the controversial long-term use of antibiotics.

Now a physician from the Dean Center for Tick Borne Illness at Spaulding Outpatient Center Boston is calling for a massive effort to fund research and help patients whose lives have been uprooted by the disease named in the 1970s after an outbreak in Lyme, Connecticut.

“This is a national emergency. This is an epidemic,” said Dr. Nevena Zubcevik, clinical co-director of the Dean Center, which filled up shortly after opening in 2015.

“We should act fast,” Zubcevik said. “It’s just getting worse every year.”

And it’s not just Lyme. Co-infections including babesiosis, anaplasmosis, Borrelia miyamotoi and the Powassan virus are expanding their reach.

Lack of good diagnostic tools and limited physician time with patients — most appointments now run between 10 to 30 minutes — “are insufficient to properly evaluate the complex clinical presentation of a patient presenting with chronic effects of tick-borne illness,” Zubcevik said.

Patients can present with a “very complicated” cluster of symptoms including stomachaches, headaches, numbness and tingling, cardiac issues, hearing loss, eye and balance problems and —most detrimental — cognitive issues that can derail school work and cost people their jobs, Zubcevik said.

Lyme in its post-acute stages is known by various names including chronic Lyme, persisting Lyme, disseminated Lyme, late-stage Lyme and post-treatment Lyme disease syndrome.

Whatever the nomenclature, it’s not uncommon, Zubcevik said.

Research by Dr. John N. Aucott at Johns Hopkins University School of Medicine shows about 20 percent of people continue to have symptoms after being treated with recommended antibiotics after being diagnosed with Lyme disease, Zubcevik said. “We need to devote more research dollars to understand why.”

Katie Crocker, of Marstons Mills, said getting bitten by ticks, first as a child, upended her life.

Now 36, she had to quit college and go on disability while she dealt with a variety of symptoms from the Lyme and co-infections including headaches, joint pain, “air hunger,” sleep disorders, poor circulation and problems gaining muscle.

Her symptoms got worse after a bad car accident, said Crocker, who has since been treated. “My life just kind of stopped from chronic illness,” she said.

“It’s like having the flu for the rest of your life,” said Aucott, assistant professor of medicine at Johns Hopkins University School of Medicine and director of the Lyme Disease Research Center.

Aucott studies both acute and post-treatment Lyme disease syndrome and says he has proof that not all Lyme patients treated with antibiotics in the acute phase of the disease recover.

His 2015 study of post-Lyme patients published in the Infectious Disease Clinics of North America journal show that immune system proteins known as CCL19 chemokines remain elevated in post-treatment patients who complain of lingering symptoms of illness.

“The immune system is still active and talking to itself and moving immune cells around,” possibly to sites of inflammation, Aucott said.

The pain isn’t all in patients’ heads, Aucott said. It’s in their bodies and possibly their nerves or nervous systems, he said.

But figuring out what is driving the immune system to act out and how to treat suffering patients is the controversial part, Aucott said.

The few physicians who specialize in Lyme disease treatment, such as now-retired Dr. Sam Donta of Falmouth, include long-term antibiotics in their arsenal on the premise that bacterial infections are still present and active.

But the Centers for Disease Control, while acknowledging that symptoms can persist beyond six months, discourages the use of long-term antibiotics, citing studies that show them to be of limited or no use compared with placebos.

Patients may claim improvement, but those cases are anecdotal, said Dr. Patrick Cahill, an infectious disease specialist at Cape Cod Hospital. Cahill, who accepted an invitation to join the Barnstable County Tick-Borne Disease Task Force of which Donta is also a member, said there is no research that shows Lyme patients improve after more than 28 days of antibiotic treatment.

Cahill said he advocates for 10 days of treatment with doxycycline in early acute stages of Lyme and up to 28 days in cases where treatment has lagged or not worked, and Lyme has gone into a disseminated stage.

Inflammation and autoimmune responses could account for some chronic cases of Lyme, Zubcevik said. But animal studies have shown live spirochetes following antibiotic treatment, which suggests elements of persistence might be a factor in some cases, she said.

In a reversal of the usual Lyme disease transmission from tick to person, a study led by Dr. Linden Hu at Tufts University suggests it’s possible that “clean” ticks got sick after feeding on people who complained of lingering symptoms of Lyme including fatigue and arthritis.

One or two of the ticks who fed on the study participants showed the presence of Lyme pathogens after being tested by polymerase chain reaction in the lab, Aucott said. The study is currently in phase two, but Aucott said he could not comment since he is participating in the research.

If pathogen-free ticks pick up the disease after feeding on Lyme patients who complain of lingering symptoms, scientists consider it a good indication that the spiral-shaped bacteria that causes Lyme disease can survive in its human host even after being zapped for 21 to 28 days with antibiotics.

But until studies are complete, chronic Lyme patients and doctors who treat them say it’s cruel to deny patients the long-term antibiotics that many say improves their lives.

Long-term oral antibiotics prescribed by Dr. Nichola LaCava, of West Boylston, who travels to the Cape to see patients twice a month at Entire Healtha and Wellness in Mashpee “saved my life,” said landscaper Shelley Bouthillette.

She said she went to several physicians on the Cape and in Boston before seeing LaCava after a year and a half of misery with symptoms that including shaking, swelling of lymph nodes and one leg and unbearable itching. “I was bed ridden,” said Bouthillette, who credits LaCava for getting her back on her feet.

Donta, an infectious disease specialist in Falmouth who retired in 2015, said that one problem with clinical trials disproving the effectiveness of long-term antibiotics is that none of them lasted longer than three months.

His own studies — which are not considered double blind since they do not include a placebo group — demonstrate that a protocol involving different types of antibiotics can eliminate symptoms almost entirely, Donta said.

Solving the mystery of Lyme calls for a lot more research dollars, said Dr. Katherine Murray, of Plymouth, who said she follows Donta’s protocols but adds sulfa treatments to the antibiotics.

“There is so much we do not know about Lyme and so much that needs to be done,” said Murray, who said she only takes patients referred by their regular physicians. “It’s everywhere now.”

And so are the patients, as Lyme has reached every state but Hawaii.

The Dean Center, located in Spaulding at the Charlestown Naval Yard, has seen more than 650 Lyme and tick-borne disease patients since its launch and now has a waiting list of about a year for new patients, said Carole Stasiowski, spokeswoman for Spaulding Rehabilitation Hospital Cape Cod in Sandwich.

“It’s not going to go away. It’s only going to get worse,” Creel said. “Cape Cod Healthcare needs to realize they need to get a doctor here.”

**Comment**

Every state in the U.S. needs to realize they need to get doctors who treat tick borne infections!

Everytime I read something about Dr. Zubcevik I literally want to hug the woman.

This article truly brought up some great points.  Please share.

Transfusion-Transmitted Babesiosis Leading to Severe Hemolysis in Sickle Cell Anemia Patients

Transfusion-transmitted babesiosis leading to severe hemolysis in two patients with sickle cell anemia

Abstract

The intracellular parasites Babesia microti and Babesia duncani can be transmitted by blood transfusion and cause severe life-threatening hemolytic anemia in high-risk patients, including those with sickle cell disease.

The rarity of the diagnosis, as well as its similar clinical presentation to delayed hemolytic transfusion reaction, may lead to a delay in diagnosis, as well as inappropriate treatment with steroids or other immunosuppressive agents.

The morbidity caused by this disease in especially vulnerable populations justifies the need for a universal blood-screening program in endemic areas.

Predators Curb Lyme Disease

https://www.nytimes.com/2017/08/02/science/ticks-lyme-disease-foxes-martens.html?smid=fb-share  Lyme Disease’s Worst Enemy? It Might Be Foxes
By AMY HARMON AUG. 2, 2017

It is August, the month when a new generation of black-legged ticks that transmit Lyme and other diseases are hatching. On forest floors, suburban estates and urban parks, they are looking for their first blood meal. And very often, in the large swaths of North America and Europe where tick-borne disease is on the rise, they are feeding on the ubiquitous white-footed mice and other small mammals notorious for harboring pathogens that sicken humans.

But it doesn’t have to be that way. A new study suggests that the rise in tick-borne disease may be tied to a dearth of traditional mouse predators, whose presence might otherwise send mice scurrying into their burrows. If mice were scarcer, larval ticks, which are always born uninfected, might feed on other mammals and bird species that do not carry germs harmful to humans. Or they could simply fail to find that first meal. Ticks need three meals to reproduce; humans are at risk of contracting diseases only from ticks that have previously fed on infected hosts.

For the study, Tim R. Hofmeester, then a graduate student at Wageningen University in the Netherlands and the lead researcher of the study, placed cameras in 20 plots across the Dutch countryside to measure the activity of foxes and stone martens, key predators of mice. Some were in protected areas, others were in places where foxes are heavily hunted.

Over two years, he also trapped hundreds of mice — and voles, another small mammal — in the same plots, counted how many ticks were on them, and tested the ticks for infection with Lyme and two other disease-causing bacteria. To capture additional ticks, he dragged a blanket across the ground.

In the plots where predator activity was higher, he found only 10 to 20 percent as many newly hatched ticks on the mice. Thus, there would be fewer ticks to pass along pathogens to next generation of mice. In the study, the density of infected “nymphs,” as the adolescent ticks are called, was at 15 percent of levels in areas where foxes and stone martens were less active.

“The predators appear to break the cycle of infection,’’ said Dr. Hofmeester, who earned his Ph.D. after the study.

Despite stuffing his pant legs into his socks and using permethrin, a tick repellent, he said he removed more than 100 ticks from his own body.

Interestingly, the predator activity in Dr. Hofmeester’s plots did not decrease the density of the mouse population itself, as some ecologists had theorized it might. Instead, the lower rates of infected ticks, Dr. Hofmeester suggested in the paper, published in Proceedings of the Royal Society B, may be the result of small mammals curtailing their own movement when predators are around.

“This is the first paper to empirically show that predators are good for your health with respect to tick-borne pathogens,” said Dr. Taal Levi, an ecologist at Oregon State University who was not involved in the study. “We’ve had the theory but this kind of field work is really hard and takes years.” He also said of Dr. Hofmeester, “Wow, I have to send him an email.”

Habitat fragmentation, hunting and the removal of larger predators like cougars may all figure into the dwindling of small mammal predators like foxes, weasels, fishers and martens, Dr. Levi said. If the study’s results are borne out by more research, public health officials might be moved to try interventions like protecting foxes or factoring the habitat needs of particular predators into land-use decisions to foster their population size. Nothing else — like culling deer or spraying lawns with tick-killing pesticide — has worked so far to stem the incidence of tick-borne disease, which is spreading in the Midwestern United States, in parts of Canada and at higher altitudes across Europe.

“The takeaway is, we shouldn’t underestimate the role predators can play in reducing Lyme disease risk,” said Richard S. Ostfeld, a senior scientist at the Cary Institute of Ecosystem Studies, who originally speculated on the importance of small mammal predators in a 2004 paper. “Let’s not discount these cryptic interactions that we don’t see very often unless we put camera traps in the woods.”

Correction: August 3, 2017
Because of an editing error, an earlier version of this article incorrectly described the number of newly hatched ticks found on mice in areas of a study where predator activity was higher. It was 10 to 20 percent, not 5 to 10 percent. The density of infected adolescent ticks in areas where foxes and stone martens were active was also incorrectly described. It was 15 percent, not 6 percent, of levels in areas where foxes and stone martens were less active.
