Research on how systemic inflammation affects the brain is only just beginning. Inflammation in schizophrenia: Pathogenetic aspects and therapeutic considerations. In vitro intracellular infection of feline microglial cells has also been demonstrated previously (31). Patients 2 to 4 each reported fatigue with accompanying neurological abnormalities that persisted for 3 to 5 years (Table 1). Patient 4 has received continuous doxycycline treatment for the past 2 years for rosacea and has experienced a decrease in headaches, back pain, and joint pain, although there are still occasional flare-ups of pain in the joints. Many of the symptoms overlap for all 4 diseases, but knowledge is your best weapon in fighting them. Although vector competence has not been established for tick transmission of Bartonella species, there is both case-based and seroepidemiological evidence supporting transmission by Rhipicephalus sanguineus and Ixodes scapularis (4, 8, 9). Bartonella as a Co-infection: Its Link to Lyme Disease 4925-03), was completed by each individual and included questions on age, gender, animal and arthropod exposure, outdoor activity, travel, clinical symptoms, and comorbid conditions. Some of the most consequential research on the topic has only been published within the last 24 months. Low-grade fever; Enlarged, tender lymph nodes that develop 1–3 weeks after exposure; A papule or pustule at the site of the scratch; Rarely, eye infections, severe muscle pain, or encephalitis (swelling of the brain) may occur. berkhoffii. NOTE: We request your email address only to inform the recipient that it was you who recommended this article, and that it is not junk mail. Frontiers in Neuroscience, 13, 651. doi:10.3389/fnins.2019.00651 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6610209/, Bogović, P. et al. 13. Bartonellosis is generally suspected when neurological symptoms are out of proportion to other systemic, chronic Lyme disease symptoms. Cats are the primary reservoir hosts for B. henselae, whereas to date, B. vinsonii subsp. Early signs are fever, fatigue, and headache. Data regarding epidemiological, clinical, management, and follow-up features were analyzed and discussed. The brain was once thought to be completely cut off from the rest of the body through the blood-brain barrier. In recent research, inflammation has been associated with other conditions including schizophrenia. Patients 2 and 3 were treated with doxycycline without obvious long-term benefits. Bartonella as a Co-infection: Its Link to Lyme Disease This protects the brain from pathogens and toxins and also prevents some medications from reaching brain tissue, for better and worse. Each blood sample was tested by PCR following direct DNA extraction from the blood sample, following preenrichment culture for at least 7 days, and following subculture onto a blood agar plate. Bartonella henselae bloodstream infection in a boy with pediatric acute-onset neuropsychiatric syndrome [online version]. and an unusual streaked rash that resembles stretch marks from pregnancy In this study, we report the isolation of B. henselae or B. vinsonii subsp. While the bacteria responsible for Lyme disease can cause neurological symptoms as well, bartonella does so on a different, more deleterious level. E: contact@galaxydx.com. Usmani-Brown S et. Depression and anxiety are so prevalent these days and I understand more than ever that there is a biological, organic trigger. Background: With the advent of more sensitive culture and molecular diagnostic testing modalities, Bartonella spp. But what, exactly, caused the child’s symptoms? It turns out that many symptoms of infection in the central nervous system come from the host response and not from the pathogen itself. The symptoms of babesia and bartonella I experience cause me much more grief than even the Lyme disease. (2019). (2017). Material and methods: We retrospectively selected patients with a CSD syndrome and Bartonella IgG titers > 1:256. Abstract. These symptoms are headache, neck ache, lower back pain, and a shooting pain that goes through my spine like my nerve is inflamed. NIH Research Matters. 11. During the subsequent 2-year period, she experienced two grand mal seizures and was treated with gabapentin for epilepsy. Seizures, severe paresis, and debilitating migraines were the predominant neurological abnormalities in patients 1, 5, and 6, respectively. with the organ(s) affected, and may include neurological signs, bone pain, weight loss or symptoms related to massive visceral lymphadenopathy. This previously healthy 49-year-old veterinarian developed progressive muscle weakness, myoclonus, paresis, and severe fatigue, which followed an acute febrile illness. Patient 6 was treated with azithromycin for 6 weeks, with a rapid and progressive decrease in the severity of migraines following the initiation of antibiotics. Serological testing at the Centers for Disease Control and Prevention identified antibodies to Bartonella spp. Six weeks after the onset of classical CSD, the boy developed difficulty in walking, an inability to run or climb stairs, and susceptibility to frequent falling, which became progressively worse during the subsequent 8 weeks (29). berkhoffii (5, 15, 16). He is the chief scientific officer for Galaxy Diagnostics, a newly formed company that will provide advanced diagnostic testing for the detection of Bartonella species infection in animals. The central nervous system used to be thought of as fairly cut off from the rest of the body, regulating the body on a kind of a one-way street of nerve pathways. Patient 5 had the most severely debilitating neurological abnormalities. Bartonella infection CAN BE quite debilitating; it is the co-infection that most often causes neurological Lyme disease and it is usually present in the more severe and chronic cases of Lyme disease. Patient 2 had reciprocal titers of antibodies to B. henselae, B. quintana, and B. vinsonii subsp. Neurological symptoms; Rash; Exactly how a Bartonella infection manifests varies substantially depending on the status of your immune system. The symptoms of babesia and bartonella I experience cause me much more grief than even the Lyme disease. Migraines (aura) Depression and anxiety are so prevalent these days and I understand more than ever that there is a biological, organic trigger. Enter multiple addresses on separate lines or separate them with commas. Evolving evidence appears to support the potential for the transmission of B. henselae to people following tick attachment. The CNS is the nerve tissue that makes up the brain and spinal column. All rights reserved. berkhoffii from, or the molecular detection of these pathogens in, samples from the patients in the study does not confirm causation. The boy gradually returned to all preillness activities with no residual neurological abnormalities. The child was not seropositive (see our previous blog post about serology testing). berkhoffii antigens, developed the highest IFA titers of antibodies to this organism, and had a decremental decrease in titers following treatment with azithromycin (Table 3). We used a previously described approach incorporating preenrichment culture of blood in Bartonella-Alphaproteobacteria growth medium (BAPGM) and PCR (16). B. henselae infections in cats, also known as feline bartonellosis, may occasionally cause a self-limiting, transient, febrile illness that lasts for approximately 48-72 hours. Bartonella vinsonii subsp. As Galaxy Diagnostics president and CEO Amanda Elam wrote in her 10-year reflection, “our bodies are complex biological systems with only a few ways to express disorder and disease, leaving our doctors with the challenging task of figuring out which of a long list of potential causal and complicating factors could be involved.”. Testing for Bartonella infections should be considered in those who are at high risk and present with persistent, non-specific rheumatic, inflammatory, or neurologic symptoms. Based upon sequential enrichment culture attempts, five individuals were found to be infected at more than one testing time point, as illustrated for patient 1 in Table 2. Sample shipments may be delayed. We report on 2 children who developed neurological symptoms of acute encephalitis or neuroretinitis. The host response that causes these symptoms can even originate in other areas of the body. We do not retain these email addresses. Bartonella is very tough on the brain because it can hide in red blood cells and cross the blood-brain barrier, which can manifest as difficult to treat psychiatric symptoms (rage was mine) and neurological events like seizures and partial paralysis. However, in 2017, researchers discovered lymph vessels in the brain. Can have acute and/or chronic patterns. The brain was once thought to be completely cut off from the rest of the body through the blood-brain barrier. 2010 Apr 8;3(1):29. that goes through my spine like my nerve is inflamed. However, the pathogen doesn’t even have to reach the brain to have an effect. Patient 2, a golf coach, traveled extensively throughout the United States and other countries, had frequent arthropod exposure, and had lived on a farm as a teenager, during which time she had been bitten by a pig and pecked frequently by roosters, turkeys, and pheasants. Neurological symptoms like poor balance, brain fog, decreased cognition, memory impairment, insomnia, and restlessness; Poor stress tolerance; Demineralization of teeth and jaw, causing chronic face and neck pain; Transient tooth pain became ill within a week after the removal of two attached ticks, whereas a second individual became ill 3 months after the removal of a tick from the scalp and, for the other two chronically ill patients, the timing of tick attachment was unknown. As cats and dogs serve as reservoir hosts for B. henselae and B. vinsonii subsp. The problems From these symptoms, and from the fact that Rocephin was the only drug that really gave me relief from Bartonella symptoms, I’ve deduced that the bulk of the infection is in my central nervous system. Her illness was characterized by severe bouts of fatigue, accompanied by subtle neurological abnormalities (Table 1). Approximately 1 year later, she developed fatigue, headaches, memory loss, disorientation, insomnia, poor coordination, tremors, and infrequent petit mal seizures. 12. Depression, anxiety and OCD are very common symptoms associated with Bartonella and the autoimmune encephalitis it causes. None of the funding sources had any role in study design, data collection, the analysis and interpretation of data, the writing of the report, or the decision to submit the manuscript for publication consideration. American Society for Microbiology berkhoffii, respectively, pet contact may represent an incompletely defined risk for disease transmission to people, particularly individuals such as veterinarians, animal handlers, and farmers with extensive animal contact (3, 7, 10, 17, 36). Remarkably common in patients with chronic neurological symptoms, especially when dominated by pain. This was especially true when the pathogen and the immune response markers were found in cerebrospinal fluid. Building on criteria and guidelines first developed in 2012, an expert panel developed a guideline for recommended treatment. It is possible an autoimmune reaction was harming the central nervous system. In the case study, researchers discuss other cases in which autoimmune disease markers where found in people and animals with bartonellosis. In the monkey brains, more than 2,000 genetic expressions were altered within six hours of exposure to B. burgdorferi.  While this is not a Bartonella species, insights into how it affects the brain may give an idea what is happening with Bartonella. Cat scratch disease (CSD) is usually self-limited, and antibiotic therapy has minimal impact on the clinical course (11, 34). Patients 4 and 5 were veterinarians who reported weekly bites or scratches from cats, dogs, rodent pocket pets, and an assortment of wild and zoo animals. Naturally infected cats are primarily asymptomatic, subclinical carriers of Bartonella henselae. Bartonella species are globally important emerging pathogens that were not known to infect animals or humans in North America prior to the human immunodeficiency virus (HIV) epidemic.Ongoing improvements in diagnostic testing modalities have allowed for the discovery of Bartonella … Substantial animal contact or recent arthropod exposure was a potential risk factor for Bartonella infection. Can be spread by a tick bite, cat scratch, and flea bites. berkhoffii. berkhoffii and B. henselae to people (7, 9, 10, 27, 36). For patient 1, IFA titers of antibodies to B. henselae, B. quintana, and B. vinsonii subsp. Several recent studies have found Bartonella DNA in questing ticks, ticks attached to animals, or ticks attached to human beings (1, 23, 35). In addition, there are previously described case studies in which tick attachment preceded the onset of illness and the documentation of B. henselae infection in children or adults (24, 26). For this patient, the same Bartonella species and strain was detected in blood and cerebrospinal fluid samples obtained 9 months apart. The child had been treated with immune-suppressing medications in addition to psychiatric medications, but had not improved. B. vinsonii subsp. Burning or stabbing sensations in the body 38. Available at: https://www.nih.gov/news-events/nih-research-matters/brain-cleaning-system-uses-lymphatic-vessels, National Institute of Mental Health. Also, similar to the 14-year-old boy in this study, one individual in the study by Eskow et al. Patient 6 was either coinfected or was chronically infected with B. henselae, the organism that was isolated, and subsequently infected with B. vinsonii subsp. Conjunctivitis results in easily seen inflammation of the usually white part of … Most cats are treated with a round of antibiotics, go back for a follow-up test a few months later, and exhibit no further problems. Bartonella infection is often found in coinfection with Lyme disease bacteria and/or the Babesia parasite. has been reported in patients with cardiovascular, neurological, and rheumatological diseases [1,2,4].If, or to what extent, persistent Bartonella spp. A healthy, unburdened immune system can eradicate Bartonella, but a toxic or disease laden body can become horribly sick from the same disease. Clearly, joint efforts by physicians and veterinarians are required to further address the role of Bartonella species as contemporary pathogens in sick animals and in human patients (8, 9, 19). Comparative medical data obtained from Bartonella-infected dogs and people would strongly support this contention (8, 9). The complete case study is free to read here. This study was approved by the North Carolina State University Institutional Review Board. Many of the symptoms overlap for all 4 diseases, but knowledge is your best weapon in fighting them. F: 919-287-2476 Available at: https://www.nimh.nih.gov/news/science-news/2017/guidelines-published-for-treating-pans-pandas.shtml, Breitschwerdt, E. B. et al. Initially, a viral infection was diagnosed, and subsequently, multiple sclerosis was diagnosed. In other words, a more intense immune response results in more intense symptoms. Journal of Clinical Medicine, 8(5), 731. https://doi.org/10.3390/jcm8050731 https://www.mdpi.com/2077-0383/8/5/731, Treadway, M. T. et al. Blood and serum samples from six individuals and cerebrospinal fluid from one patient were submitted by an attending physician to the Intracellular Pathogens Research Laboratory, Center for Comparative Medicine and Translational Research, College of Veterinary Medicine, North Carolina State University, Raleigh, for attempted isolation of a Bartonella species. Similar to the subjects in a previous study in which the preenrichment approach was used, each person in this study was immunocompetent and each had a history of animal or arthropod contact (5). Patient 3 owned a horse farm, had frequent arthropod exposure, and reported at least yearly cat scratches. Despite multiple attempts, cloning and sequencing of the initial Bartonella amplicon were not successful; however, B. henselae DNA from an agar plate isolate obtained after BAPGM preenrichment culture was sequenced. Peripheral Neuropathy: numbness and tingling in my feet, hands & face; Chronic muscle pain in my thoracic & neck (and I mean excruciating) Rib pain (see further notes) Joint pain (mostly knees and hips. At this time there are 26 subspecies of Bartonella (Henselae and Cinnuate). The involvement of the central nervous system in patients with CSD is infrequent, and the spontaneous resolution of neurological abnormalities, without residual neurological dysfunction, is the most frequently reported outcome (18). Brain cleaning system uses lymphatic vessels. Also, consistent with the data in the previous report, patients 2, 3, and 4 were middle-aged women who reported neurocognitive abnormalities including fatigue, insomnia, memory loss, disorientation, and frequent headaches. (2019). A single blood draw might have missed confirming a diagnosis of bartonellosis. This research was supported by the State of North Carolina and in part by the Sigmon Trust, Bayer Animal Health, IDEXX Laboratories, and a grant awarded to E. B. Breitschwerdt, R. G. Maggi, and C. W. Woods from the Southeastern Center for Emerging Biological Threats. berkhoffii is an important, emerging, intravascular bacterial pathogen that has been recently isolated from immunocompetent patients with endocarditis, arthritis, neurological disease and vasoproliferative neoplasia. Bartonella can cause lymph nodes to swell 1-2 weeks after infection. Bartonella vinsonii subsp. Symptoms of a Bartonella infection. So far 8-12 Bartonella species have been discovered that can cause disease in humans. Cats can carry the bacteria in their systems for months without any symptoms, so if your pet starts to show signs of swollen glands, lethargy, or sore muscles, you definitely want to get her to the vet. Patient 6 was the 14-year-old son of a veterinarian, and although exposed to both cats and dogs, the boy did not report previous scratches or bites. Neurological symptoms following a cat scratch have also been described in association with B. quintana infection, and recent evidence indicates that cats can harbor B. quintana (6, 13, 32, 37). antigens. Only after antibiotic treatment did his symptoms resolve. Identical B. henselae 16S-23S ITS sequences were amplified from samples obtained from patient 1 on three independent occasions. Blood from the 14-year-old boy described in this study was provided by the attending neurologist when the boy's mother, a companion animal veterinarian, contacted our laboratory, to which she routinely submitted diagnostic samples for testing for tick-borne organisms in the blood of cats and dogs.
