Abstract
Borrelia miyamotoi, transmitted by Ixodes spp. ticks, was recognized as an agent of hard tick relapsing fever in the United States in 2013. Nine state health departments in the Northeast and Midwest have conducted public health surveillance for this emerging condition by using a shared, working surveillance case definition. During 2013-2019, a total of 300 cases were identified through surveillance; 166 (55%) were classified as confirmed and 134 (45%) as possible. Median age of case-patients was 52 years (range 1-86 years); 52% were male. Most cases (70%) occurred during June-September, with a peak in August. Fever and headache were common symptoms; 28% of case-patients reported recurring fevers, 55% had arthralgia, and 16% had a rash. Thirteen percent of patients were hospitalized, and no deaths were reported. Ongoing surveillance will improve understanding of the incidence and clinical severity of this emerging disease.

Abstract
Background Tick-borne disease caused by B. miyamotoi (BMD) usually manifest as a febrile illness in humans. Complications include relapsing fever and in rare occasions involvement of the central nervous system. Only a few cases of meningoencephalitis have been described, mostly in immunosuppressed patients. Case presentation A 70-year-old female receiving immunosuppressive rituximab therapy presented with frontal headache, dizziness, nausea, vomiting and chills. Clinical laboratory blood analyses were normal. Cerebrospinal fluid (CSF) was translucent and analysis showed increased leucocyte count (187 106/L) and elevated level of protein (1056 mg/L). Empiric antibiotic treatment was initiated. The patient showed an early symptomatic relief and 24 h after admission she was discharged from the hospital and antibiotic treatment was discontinued. Two weeks after hospitalisation the B. miyamotoi specific PCR turned out positive in both CSF and serum. At the time, the patient was recovered with mild residual headache. She was treated with high dose doxycycline and her subtle symptoms disappeared. Conclusions To our knowledge, we present the first patient with BMD-associated meningitis in Norway, one of eight cases reported worldwide. The patient had mild symptoms and received an early diagnosis. A more severe progression or relapse of disease may have been prevented by antibiotic treatment. BMD should be considered as causes of aseptic meningitis, especially in immunosuppressed patients living in endemic areas.

Abstract
Borrelia miyamotoi is an emerging pathogen that causes a febrile illness and is transmitted by the same hard-bodied (ixodid) ticks that transmit several other pathogens, including Borrelia species that cause Lyme disease. B. miyamotoi was discovered in 1994 in Ixodes persulcatus ticks in Japan. It was first reported in humans in 2011 in Russia. It has subsequently been reported in North America, Europe, and Asia. B. miyamotoi infection is widespread in Ixodes ticks in the northeastern, northern Midwestern, and far western United States and in Canada. In endemic areas, human B. miyamotoi seroprevalence averages from 1 to 3% of the population, compared with 15 to 20% for B. burgdorferi. The most common clinical manifestations of B. miyamotoi infection are fever, fatigue, headache, chills, myalgia, arthralgia, and nausea. Complications include relapsing fever and rarely, meningoencephalitis. Because clinical manifestations are nonspecific, diagnosis requires laboratory confirmation by PCR or blood smear examination. Antibiotics are effective in clearing infection and are the same as those used for Lyme disease, including doxycycline, tetracycline, erythromycin, penicillin, and ceftriaxone. Preventive measures include avoiding areas where B. miyamotoi-infected ticks are found, landscape management, and personal protective strategies such as protective clothing, use of acaricides, and tick checks with rapid removal of embedded ticks.

Abstract
Borrelia miyamotoi is an emerging tick-borne pathogen in the Northern Hemisphere and is the causative agent of Borrelia miyamotoi disease (BMD). Borrelia miyamotoi is vectored by the same hard-bodied ticks as Lyme disease Borrelia, yet phylogenetically groups with relapsing fever Borrelia, and thus, has been uniquely labeled a hard tick-borne relapsing fever Borrelia. Burgeoning research has uncovered new aspects of B. miyamotoi in human patients, nature, and the lab. Of particular interest are novel findings on disease pathology, prevalence, diagnostic methods, ecological maintenance, transmission, and genetic characteristics. Herein, we review recent literature on B. miyamotoi, discuss how findings adapt to current Borrelia doctrines, and briefly consider what remains unknown about B. miyamotoi.

Prevalence and clinical manifestation of Borrelia miyamotoi in Ixodes ticks and humans in the northern hemisphere: a systematic review and meta-analysis. THE LANCET. MICROBE 2022; 3:e772-e786. [PMID: 36113496 DOI: 10.1016/s2666-5247(22)00157-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 04/30/2022] [Accepted: 05/31/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Various studies have evaluated the infection of Ixodes ticks and humans with the relapsing fever spirochaete Borrelia miyamotoi. However, to our knowledge, the prevalence of infection and disease has not been assessed systematically. We aimed to examine the prevalence of B miyamotoi in Ixodes ticks and humans, and the disease it can cause, in the northern hemisphere. METHODS For this systematic review and meta-analysis, we searched PubMed and Web of Science up to March 1, 2021. Studies assessing Ixodes tick infection published since Jan 1, 2011 were eligible, whereas no time limitation was placed on reports of human infection and disease. We extracted B miyamotoi test positivity ratios and used a random-effects model to calculate estimated proportions of infected ticks, infected humans, and human disease with 95% CI. This study was registered with PROSPERO, CRD42021268996. FINDINGS We identified 730 studies through database searches and 316 additional studies that referenced two seminal articles on B miyamotoi. Of these 1046 studies, 157 were included in the review, reporting on 165 637 questing ticks, 45 608 unique individuals, and 504 well described cases of B miyamotoi disease in humans. In ticks, the highest prevalence of B miyamotoi was observed in Ixodes persulcatus (2·8%, 95% CI 2·4-3·1) and the lowest in Ixodes pacificus (0·7%, 0·6-0·8). The overall seroprevalence in humans was 4·4% (2·8-6·3), with significantly (p<0·0001) higher seroprevalences in the high-risk group (4·6%, 2·6-7·1), participants with confirmed or suspected Lyme borreliosis (4·8%, 1·8-8·8), and individuals suspected of having a different tick-borne disease (11·9%, 5·6-19·9) than in healthy controls (1·3%, 0·4-2·8). Participants suspected of having a different tick-borne disease tested positive for B miyamotoi by PCR significantly more often than did the high-risk group (p=0·025), with individuals in Asia more likely to test positive than those in the USA (odds ratio 14·63 [95% CI 2·80-76·41]). INTERPRETATION B miyamotoi disease should be considered an emerging infectious disease, especially in North America and Asia. Prospective studies and increased awareness are required to obtain further insights into the burden of disease. FUNDING ZonMW and the European Regional Development Fund (Interreg).

Abstract
Borrelia miyamotoi is an underdiagnosed cause of tick-borne illness in endemic regions and, in rare cases, causes neurological disease in immunocompetent patients. Here, we present a case of serologically confirmed Borrelia miyamotoi meningoencephalitis in an otherwise healthy patient who rapidly improved following initiation of antibiotic therapy.

Abstract
An adult male presented to a hospital in southwestern Connecticut with tachypnea, generalized weakness, altered mental status, and relapsing fever with maximum recorded temperature of 106 °F. He required active cooling, antipyretic therapy, broad spectrum antibiotics, and intubation for airway protection after an episode of emesis. Initial laboratory and imaging workup were remarkable for elevated inflammatory markers, acute kidney injury, and bilateral lower lobe infiltrates. Further workup with lumbar puncture and electroencephalography were unrevealing. Extensive testing for causes of relapsing fever including tickborne diseases revealed that the patient was seropositive for Borrelia miyamotoi. Notably, he had no rash, and workup found no evidence of coinfection by other Borrelia, Ehrlichia or Anaplasma species. This case illustrates the need for clinicians to test for tick-borne diseases when evaluating for cases of relapsing fever in New England and is among the first case reports to demonstrate Borrelia miyamotoi as a cause of severe pyrexia.

Abstract
HISTORY A 35-year-old, previously healthy woman presented with short history of headache and fever. Several other family members reported active hand, foot, and mouth disease. FINDINGS Clinical findings showed subfebrile temperatures and a prominent meningism. Cerebrospinal fluid and computed tomography of the head were unrevealing. Subsequent PCR-analysis of the cerebrospinal fluid was positive for Enteroviral-RNA. DIAGNOSIS AND THERAPY Enteroviral-meningitis was diagnosed. The empirically administered antimicrobial therapy was stopped and further diagnostic tests could be withheld. COURSE Symptom-oriented therapy resulted in complete resolution within the next few days. CONCLUSIONS Our case emphasizes that, in patients with typical signs of meningeal irritation, normal cellular analysis of the cerebrospinal fluid does not exclude the presence of infectious meningitis. The astute clinician should be reminded that this constellation is highly suggestive of enteroviral meningitis.

Abstract
PURPOSE OF REVIEW This article reviews current epidemiologic trends, clinical presentations, and diagnostic strategies for central nervous system (CNS) infections in human immunodeficiency virus-negative (HIV) patients immunocompromised by their underlying disease or by receipt of immunosuppressive or immunomodulating therapies. Three patient groups are considered: (1) cancer patients; (2) hematopoietic or solid organ transplantation recipients; and (3) patients with autoimmune or inflammatory conditions requiring therapies that alter the host immune response. RECENT FINDINGS Clinical presentations, associated neuroimaging, and cerebrospinal fluid (CSF) abnormalities differ between immunocompromised and immunocompetent patients. Infections can trigger the emergence of neurotropic antibodies or inflammatory conditions due to treatment with cancer immunotherapies. Unbiased metagenomic assays to identify obscure pathogens help clinicians navigate the increasing range of conditions affecting the growing population of patients with altered immunity. Awareness of clinical presentations and disease and drug-specific risks is important for early diagnosis and intervention in these often life-threatening infections and their noninfectious mimes.
