Tick-Borne Relapsing Fever in the White Mountains, Arizona, USA, 2013-2018.

Emerg Infect Dis 2019 Apr;25(4):649-653

Tick-borne relapsing fever (TBRF) is a bacterial infection transmitted by tick bites that occurs in several different parts of the world, including the western United States. We describe 6 cases of TBRF acquired in the White Mountains of Arizona, USA, and diagnosed during 2013-2018. All but 1 case-patient had recurrent fever, and some had marked laboratory abnormalities, including leukopenia, thrombocytopenia, hyperbilirubinemia, and elevated aminotransaminases. Read More

Louse-borne relapsing fever (Borrelia recurrentis infection).

Authors:
David A Warrell

Epidemiol Infect 2019 Jan;147:e106

Nuffield Department of Clinical Medicine,University of Oxford,Oxford,UK.

Louse-borne relapsing fever (LBRF) is an epidemic disease with a fascinating history from Hippocrates' times, through the 6th century 'Yellow Plague', to epidemics in Ireland, Scotland and England in the 19th century and two large Afro-Middle Eastern pandemics in the 20th century. An endemic focus persists in Ethiopia and adjacent territories in the Horn of Africa. Since 2015, awareness of LBRF in Europe, as a re-emerging disease, has been increased dramatically by the discovery of this infection in dozens of refugees arriving from Africa. Read More

Values of diagnostic tests for the various species of spirochetes.

IRD, AP-HM, MEPHI, IHU-Méditerranée Infection, Aix Marseille Université, 13005 Marseille, France.

Bacteria of the Borrelia burgdorferi sensu lato complex, responsible for Lyme disease, are members of the spirochetes phylum. Diagnostic difficulties of Lyme disease are partly due to the characteristics of spirochetes as their culture is tedious or even impossible for some of them. We performed a literature review to assess the value of the various diagnostic tests of spirochetes infections of medical interest such as Lyme borreliosis, relapsing fever borreliae, syphilis, and leptospirosis.

Phyloproteomic and functional analyses do not support a split in the genus Borrelia (phylum Spirochaetes).

BMC Evol Biol 2019 Feb 13;19(1):54. Epub 2019 Feb 13.

UMR BIPAR, INRA, ANSES, Ecole Nationale Vétérinaire d'Alfort, Université Paris-Est, 94700, Maisons-Alfort, France.

Background: The evolutionary history of a species is frequently derived from molecular sequences, and the resulting phylogenetic trees do not include explicit functional information. Here, we aimed to assess the functional relationships among bacteria in the Spirochaetes phylum, based on the biological processes of 42,489 proteins in reference proteomes of 34 Spirochaetes species. We tested the hypothesis that the species in the genus Borrelia might be sufficiently different to warrant splitting them into two separate genera. Read More

Molecular prevalence and ecoregion distribution of select tick-borne pathogens in Texas dogs.

Transbound Emerg Dis 2019 Feb 10. Epub 2019 Feb 10.

Department of Veterinary Pathobiology, College of Veterinary Medicine and Biomedical Sciences, Texas A&M University, College Station, Texas.

Tick-borne diseases (TBD), caused by borrelial, rickettsial and babesial pathogens, are common across the United States and can cause severe clinical disease in susceptible hosts, such as domestic dogs. However, there are limited TBD molecular epidemiological reports for dogs in Texas, and none for the non-Lyme borrelial pathogen responsible for causing tick-borne relapsing fever (TBRF). Therefore, data to support the prevalence of TBRF in the canine population is inadequate. Read More

Immunological Responses to the Relapsing Fever Spirochete in Infected Rhesus Macaques: Implications for Pathogenesis and Diagnosis.

Infect Immun 2019 Apr 25;87(4). Epub 2019 Mar 25.

Department of Pediatrics, National School of Tropical Medicine, Houston, Texas, USA.

The global public health impact of relapsing fever (RF) spirochetosis is significant, since the pathogens exist on five of seven continents. The hallmark sign of infection is episodic fever and the greatest threat is to the unborn. With the goal of better understanding the specificity of B-cell responses and the role of immune responses in pathogenicity, we infected rhesus macaques with (a new world RF spirochete species) by tick bite and monitored the immune responses generated in response to the pathogen.

Unlike , the agent of Lyme disease, is closely related to relapsing fever spirochetes, such as Some authors have suggested that the disease caused by should be considered a hard-tick-transmitted relapsing fever, and thus, the main mode of confirming a diagnosis for that infection, microscopy to analyze a blood smear, may have clinical utility. To determine whether blood smears may detect in the blood of acute BMD patients, we made standard malariological thick smears from anticoagulated blood samples that were previously determined to contain this agent (by PCR) and analyzed them for morphological evidence of spirochetes.

Cochrane Database Syst Rev 2018 Nov 13;11:CD012774. Epub 2018 Nov 13.

Department of Pediatrics, Karjoo Family Center for Pediatric Gastroenterology, SUNY Upstate Medical University, 725, Irving Street, Suit 501, Syracuse, NY, USA, 13210.

Background: Inflammatory bowel disease (IBD) is a chronic, relapsing disease of the gastrointestinal tract that is thought to be associated with a complex interplay between microbes and the immune system, leading to an abnormal inflammatory response in genetically susceptible individuals. Dysbiosis, characterized by the alteration of the composition of the resident commensal bacteria in a host compared to healthy individuals, is thought to play a major role in the pathogenesis of ulcerative colitis (UC) and Crohn's disease (CD), two subtypes of IBD. There is growing interest to correct the underlying dysbiosis through the use of fecal microbiota transplantation (FMT) for the treatment of IBD. Read More

Early neutropenia with thrombocytopenia following alemtuzumab treatment for multiple sclerosis: case report and review of literature.

Clin Neurol Neurosurg 2018 Dec 3;175:134-136. Epub 2018 Nov 3.

Department of Neurology and Stroke Unit "A. Cardarelli Hospital", via A. Cardarelli 9, 80131, Naples, Italy; Multiple Sclerosis Centre "A. Cardarelli Hospital", via A. Cardarelli 9, 80131 Naples, Italy.

Alemtuzumab is a monoclonal antibody targeting the CD52 antigen used in the treatment of relapsing-remitting multiple sclerosis (RRMS). CD52 is expressed by lymphocytes and monocytes but less by neutrophils and not by platelets. We present a case of a 38-year-old woman with RRMS who developed early neutropenia with thrombocytopenia after alemtuzumab infusion. Read More

Noncaseating suppurative granulomatous lymphadenitis in adult onset Still's disease - a diagnostic dilemma in a tuberculosis-endemic region: a case report.

J Med Case Rep 2018 Oct 15;12(1):299. Epub 2018 Oct 15.

Sri Jayewardenepura General Hospital and Post-graduate Training Institute, Sri Jayawardenepura Kotte, Western Province, Sri Lanka.

Background: Lymphadenopathy is not an uncommon presentation of adult onset Still's disease: it is present in up to two thirds of patients with adult onset Still's disease. The characteristic appearance of lymphadenopathy is described as intense, paracortical immunoblastic hyperplasia. Changes in light microscopy may resemble lymphoma, but immunohistochemistry reveals a benign polyclonal B cell hyperplasia. Read More

A delayed diagnosis: recurrent fever and beta thalassaemia.

BMJ Case Rep 2018 Sep 30;2018. Epub 2018 Sep 30.

1st Department of Medicine, Faculty of Medicine, National and Kapodistrian University of Athens, Athens, Greece.

Familial Mediterranean fever and beta-thalassaemia are two genetic disorders, with a largely common geographical distribution. However, they have not much else in common, as the first is an autoinflammatory disorder, while the other is a haemoglobinopathy. We describe a patient with known beta-thalassaemia intermedia who presented with recurrent fevers and he was diagnosed with familial Mediterranean fever 2 years later. Read More

Louse-borne relapsing fever (LBRF) is known to have killed millions of people over the course of European history and remains a major cause of mortality in parts of the world. Its pathogen, , shares a common vector with global killers such as typhus and plague and is known for its involvement in devastating historical epidemics such as the Irish potato famine. Here, we describe a European and historical genome of , recovered from a 15th century skeleton from Oslo. Read More
