Dear RM Agents and Readers,

This post is especially for the medical profession but if you are like myself and have been delving deep into many of these illness's looking for answers then be my guest.

It is also good to remember that Cat Scratch Fever/Bartonella is especially a problem with those of Rh negative blood whether as your blood type or on your genome. Info to help you better understand how that works below:

http://www.biology.arizona.edu/human_bio/problem_sets/blood_types/rh_factor.html

Many with the condition known as Morgellons have Rh negative blood or have it on their genome. Those that present as Rh negative become much more ill with Morgellons.

Someone on the boards was suggesting that Bartonella was Morgellons; after realizing that there was horizontal gene transfer involved in Bartonella it was getting my attention.

Many Blessings,

Key Clinical Message

Recently, BAPGM enrichment culture has documented Bartonella bacteremia in previously healthy, “nonimmunocompromised” patients following arthropod exposures. Neurobartonellosis should be among the differential diagnoses for patients with persistent or recurrent neurological symptoms of undetermined etiology. Microbiological and immunological testing should be concurrently pursued to determine whether defective immune function accompanies Bartonella bacteremia.
Case Reports
Patient 1

A 49-year-old female veterinarian from California was previously healthy working 60 h a week managing a cat shelter with 500 cats. These factors may have predisposed acquisition of B. henselae and failure to immunologically eliminate the infection. In October 2011, she experienced an extensive infestation of mange mites (Sarcoptes scabiei or Notoedres cati) after handling an infested cat. One month later, she experienced an episode of confusion and severe headache. There was no prior history of headaches or migraines. That evening, she again became confused, experienced a 15-min episode of total aphasia, witnessed by her husband, and had a headache. All symptoms resolved after 3 h. Over the next few months, she continued to have headaches, episodic confusion, and aphasia. Because an aura preceded symptoms, she would stop performing surgery, sit down, or stop driving. Initially, these episodes occurred one to two times a month; however, over the next 4 years, all symptoms increased in frequency and duration, occurring 20–25 days a month and lasting minutes to hours. She subsequently developed seizures and balance and disequilibrium problems causing gait impairment and falls.

She was examined by multiple physicians. An extensive neurological workup included an MRI performed in August 2013; all results were negative except for electroencephalographic “left temporal lobe slowing.” After treatment with the anticonvulsant levetiracetam, she reported a 3-week period of mental clarity and felt normal. Subsequently, symptoms recurred and she did not respond to dose adjustment or additional medications. Her illness progressively worsened, and she stopped working 4 years after symptom onset.

Based on her clinical history, high arthropod and feral cat exposure risk, ambiguous neurological test results, and failure to improve with medical therapy, a search for an infectious cause was initiated. Initial serology results (Quest Diagnostics, Inc.) were negative for Borrelia burgdorferi, Anaplasma phagocytophilum, Ehrlichia chaffeensis, Babesia, Bartonella, Toxoplasma, and Cryptococcus. In December 2014, a repeat MRI revealed left frontal convexity falx calcifications. A SPECT scan documented heterogeneous decreased uptake bilaterally in the frontal and anterior temporal lobes with greater decrease involving the left hemisphere. Cerebrospinal fluid analyses were within laboratory reference ranges. Due to progressive illness and lack of a diagnosis, immunological testing was performed. There were decreased total IgG and deficiencies in subclasses 1, 2, and 3. CD3, CD4, and CD8 absolute cell counts were abnormally low, and a natural killer cell (NK) function assay was profoundly low (Table 1).

Because immunological test results were abnormal, additional infectious disease testing was pursued. Given her daily work with cats, frequent exposure to fleas, and historical mite infestation, Bartonella spp. bacteremia remained a diagnostic consideration. EDTA-anticoagulated blood specimens were screened for Bartonella using the Bartonella alpha-proteobacteria growth medium (BAPGM) enrichment culture/PCR diagnostic platform. (Bartonella enrichment PCR™ or ePCR™ (Galaxy Diagnostics, Inc., Research Triangle Park, NC)) Serological analysis of Bartonella henselae and Bartonella quintana was performed using indirect fluorescent antibody (IFA) testing (Galaxy Diagnostics, Inc., Research Triangle Park, NC). Bartonella henselae DNA was amplified and sequenced from a 21-day BAPGM enrichment blood culture. Serum was not reactive to B. henselae or B. quintana antigens at 1:16 or 1:32 screening dilutions. Genus PCR assays (Galaxy Diagnostics, Inc., Research Triangle Park, NC) for Anaplasma, Babesia, Ehrlichia, and Rickettsia spp. were negative.

Based on these results, she was treated with clarithromycin, rifampin, and intravenous gamma globulin every 3 weeks. By week six of antibiotic/IVIG administration, her headaches slowly improved, and she returned to work. After 9 months of antibiotics, she was B. henselae and B. quintana seroreactive at titers of 1:128 and 1:64, respectively. Three BAPGM enrichment blood cultures collected on alternate days were PCR negative. During the subsequent 9-month follow-up, she has experienced no seizures. An MRI, repeated 14 months after the December 2014 MRI study, and 11 months after beginning antibiotics, was unchanged. Her previously abnormal lymphocyte subsets normalized, although NK function remained depressed at 10.
Patient 2

A 69-year-old previously healthy woman hiking in New York State during November 2013 became acutely ill 3 weeks after returning to California. She reported flu-like symptoms including headaches, nausea, vertigo with disequilibrium, and fatigue but no fever or pain. She developed a bulls-eye rash on her right infraclavicular fossa, consistent with erythema chronicum migrans. Lyme disease was diagnosed by another physician, who initiated doxycycline treatment for 2 weeks.

She continued to have symptoms and was examined by the primary author 10 days after starting doxycycline (Open Medicine Institute, Mountain View, CA). Laboratory testing results for Borrelia burgdorferi, Anaplasma phagocytophilum, Ehrlichia chaffeensis, Babesia, and Bartonella antibodies (Quest Diagnostics, Inc.) were negative. Doxycycline was continued for 4 weeks resulting in a transient decrease in symptoms. Headaches, vertigo, disequilibrium, and nausea recurred 2 weeks after completing antibiotics. Treatment with doxycycline and azithromycin initiated on January 2014 resulted in symptomatic improvement; however, antibiotic administration ceased after 2 weeks due to a photosensitivity reaction while visiting Florida. Symptoms returned after 2 weeks, only to resolve again with amoxicillin and azithromycin administration. Within 5 days, she developed severe diarrhea, antibiotics were stopped, and within 3 days, her headache and vertigo returned. A neurology workup in August 2014, including MRI, MRA, and cerebral angiogram, detected no abnormalities.

In October 2014, she was treated with minocycline and metronidazole for headaches, vertigo, and disequilibrium. After 5 weeks, there was symptomatic improvement that continued through 8 weeks, when antibiotics were stopped. Six weeks later, all symptoms recurred. In April 2015, immunological testing documented an IgG subclass 3 deficiency; low absolute CD3, CD8, and CD19 cell counts; and decreased NK cell function (Table 1). Repeat serological testing (Quest Diagnostics, Inc.) for tickborne diseases remained negative. Bartonella henselae DNA was amplified and sequenced from a 21-day BAPGM enrichment blood culture (Bartonella enrichment PCR™ or ePCR™ (Galaxy Diagnostics, Inc., Research Triangle Park, NC)). Serum was not B. henselae or B. quintana seroreactive at 1:16 or 1:32 screening dilutions. Genus PCR assays (Galaxy Diagnostics, Inc., Research Triangle Park, NC) for Anaplasama, Babesia, Ehrlichia, and Rickettsia spp. were negative. After being treated with clarithromycin and rifampin for 5 months, headaches and vertigo were almost completely resolved and she remained B. henselae and B. quintana IFA seronegative, although lymphocyte subsets and NK function remained abnormal. She remained B. henselae or B. quintana seronegative, and three BAPGM enrichment blood cultures collected on alternate days were PCR negative.
Discussion

Two important clinical observations evolved out of the microbiological, immunological, and therapeutic findings associated with the medical management of these two patients. First, persistent or recurrent neurological symptoms of undetermined etiology in patients with historical vector exposures should prompt testing for bartonellosis. Historically, B. henselae infections in immunocompetent individuals have been associated with self-limiting cat scratch disease, whereas recent research supports persistent and potentially relapsing bacteremia [1-3]. As previously reported [2, 3], both of these B. henselae bacteremic patients experienced headaches and disequilibrium. Patient 1 also experienced seizures, episodic confusion, and aphasia, which resolved completely following antibiotic therapy, despite persistence of the MRI abnormalities [1]. Secondly, immunological testing should be concurrently pursued to determine whether defective immune function accompanies neurological symptoms. Both patients had immunological abnormalities, including suppression of NK function, despite lacking a prior medical history indicative of immunodeficiency. The extent to which persistent B. henselae bacteremia may have induced immunocompromise or whether a chronic latent infection resulted in bacterial reactivation is unknown. It is important to note that after 9 months of treatment, the CD3, CD4, and CD19 deficiencies in Patient 1 resolved, while Patient 2 remained immunologically impaired after 5 months of therapy. There remains a substantial need for sequential electroencephalographic, MRI, immunological, and bacteriological patient data to guide physician decision making in patients with longstanding B. henselae bacteremia.

Using a previously validated diagnostic approach [3, 4], B. henselae bacteremia was confirmed in both patients by BAPGM enrichment blood culture, PCR amplification, and DNA sequence confirmation. Importantly, PCR did not amplify B. henselae DNA from patient's blood, serum, 8-day, or 14-day BAPGM enrichment blood cultures, supporting the need for prolonged bacterial incubation times to obtain PCR confirmation for some B. henselae bacteremic patients. Consistent with previous studies[3, 5] in which a subset of patients with persistent bacteremia were not IFA seroreactive to a panel of Bartonella sp. antigens, neither patient was initially B. henselae or B. quintana IFA seroreactive, whereas antibody reactivity was documented after antibiotic treatment in Patient 1, potentially due to enhanced immunological recognition of antigenic epitopes. Based upon these patients and previously published studies [3, 5], enrichment blood culture and PCR should be used in conjunction with Bartonella sp. serological analysis when attempting to confirm bacteremic infection with a Bartonella sp.

Vector transmission of B. henselae was the suspected source of infection for both patients. The veterinarian had ongoing vector (flea, mite, and potentially ticks) and animal exposure, which are occupational risks for animal health workers [3, 5]. The cat flea (Ctenocephalides felis) transmits B. henselae among cats that develop a relapsing bacteremia and remain persistently infected reservoir hosts for months to years [6]. Although there is no evidence that cat-associated mites (S. scabiei or N. cati) are vector competent for the transmission of Bartonella species, rat mite (Ornithonyssus bacoti) and pigeon mite (Dermanyssus spp.) transmissions of B. henselae and B. quintana, respectively, have been suspected [7, 8]. Due to an acute-onset illness and presumed tick attachment in a Lyme-endemic region with the subsequent development of erythema chronicum migrans, Lyme disease was initially suspected in Patient 2. Rapid treatment with doxycycline may have prevented serodiagnostic confirmation of B. burgdorferi transmission, whereas testing for other tickborne pathogens was negative. Although tick transmission of B. henselae has not been proven, organism-specific DNA has been PCR-amplified and sequenced from Ixodes sp. ticks [9], vector competence for Bartonella transmission has been demonstrated in a rodent model [10], and French investigators have recently documented Bartonella spp. bacteremia in patients following tick exposures [11].

Historically, systemic bartonellosis has been reported in immunocompromised patients, such as those with HIV/AIDS and transplant recipients. Recently, infection with Bartonella spp. has been reported in healthy asymptomatic Brazilian blood donor candidates[12] and in previously immunocompetent patients with chronic neurological or rheumatologic symptoms [2, 3, 5].

Because Bartonella spp. can infect erythrocytes, endothelial cells, and various macrophage-type cells, including brain-derived dendritic cells in vitro, the spectrum of neurological symptoms attributable to bartonellosis appear to be extremely diverse among patients [1, 2]. Physicians should be aware of the rapidly increasing number of Bartonella spp., the large number of proven and suspected arthropod vectors, and the large number of reservoir hosts, all of which are collectively contributing to the enhanced recognition of neurobartonellosis as a medically important emerging infectious disease.
