CXCL13 in patients with facial palsy caused by varicella zoster virus and Borrelia burgdorferi: a comparative study.

Diagn Microbiol Infect Dis 2020 May 30;98(1):115095. Epub 2020 May 30.

Department of Infectious Diseases, Sahlgrenska University Hospital, Gothenburg, Sweden; Department of Infectious Diseases, Institute of Biomedicine, Sahlgrenska Academy, University of Gothenburg, Sweden.

High cerebrospinal fluid (CSF) concentrations of the chemokine CXCL13 have been associated with Lyme neuroborreliosis (LNB), and have recently been studied as a potential diagnostic marker. It has proven difficult to establish a reliable diagnostic cut-off, possibly in part due to heterogenicity of case-control groups. Our purpose was to investigate CSF CXCL13 concentrations in patients with similar clinical presentations, facial palsy. Read More

Northern and southern blacklegged (deer) ticks are genetically distinct with different histories and Lyme spirochete infection rates.

Sci Rep 2020 Jun 24;10(1):10289. Epub 2020 Jun 24.

Department of Microbiology, University of Massachusetts, Amherst, United States of America.

Lyme borreliosis (LB) is the archetypal emerging zoonosis and is dependent on transmission by ticks in the genus Ixodes. Understanding the origin, maintenance, and spread of these ticks contributes much to our understanding of the spread of LB and other disease agents borne by these ticks. We collected 1232 Ixodes scapularis ticks from 17 east coast sites ranging from New Hampshire to Florida and used mtDNA, three nuclear genetic loci, and incorporated Bayesian analyses to resolve geographically distinct tick populations and compare their demographic histories.

Extremely High Creatine Kinase Activity in Rhabdomyolysis without Acute Kidney Injury.

Am J Case Rep 2020 May 20;21:e924347. Epub 2020 May 20.

Department of Internal Medicine, University of Pittsburgh Medical Center Pinnacle, Harrisburg, PA, USA.

BACKGROUND Elevation of creatine kinase (CK) activity has been shown to be predictive of acute kidney injury (AKI) in rhabdomyolysis. Patients with extremely high CK activity with preserved renal function are uncommon. This report describes a case of non-traumatic rhabdomyolysis, with a markedly elevated CK activity, without associated AKI. Read More

Establishment of an in vitro RNA polymerase transcription system: a new tool to study transcriptional activation in Borrelia burgdorferi.

Sci Rep 2020 May 19;10(1):8246. Epub 2020 May 19.

Department of Medical Microbiology and Immunology, Creighton University, Omaha, NE, 68105, USA.

The Lyme disease spirochete Borrelia burgdorferi exhibits dramatic changes in gene expression as it transits between its tick vector and vertebrate host. A major hurdle to understanding the mechanisms underlying gene regulation in B. burgdorferi has been the lack of a functional assay to test how gene regulatory proteins and sigma factors interact with RNA polymerase to direct transcription.

The Ultimate Poker Face: A Case Report of Facial Diplegia, a Guillain-Barré Variant.

Clin Pract Cases Emerg Med 2020 May 23;4(2):150-153. Epub 2020 Apr 23.

Brooke Army Medical Center, Department of Emergency Medicine, Fort Sam Houston, Texas.

Introduction: Facial diplegia, a rare variant of Guillain-Barré syndrome (GBS), is a challenging diagnosis to make in the emergency department due to its resemblance to neurologic Lyme disease.

Case Report: We present a case of a 27-year-old previously healthy man who presented with bilateral facial paralysis.

Discussion: Despite the variance in presentation, the recommended standard of practice for diagnostics (cerebrospinal fluid albumin-cytological dissociation) and disposition (admission for observation, intravenous immunoglobulin, and serial negative inspiratory force) of facial diplegia are the same as for other presentations of GBS.

Committee Opinion No. 399: Management of Tick Bites and Lyme Disease During Pregnancy.

J Obstet Gynaecol Can 2020 05;42(5):644-653

Halifax, NS.

Objective: Lyme disease is an emerging infection in Canada caused by the bacterium belonging to the Borrelia burgdorferi sensu lato species complex, which is transmitted via the bite of an infected blacklegged tick. Populations of blacklegged ticks continue to expand and are now established in different regions in Canada. It usually takes more than 24 hours of tick attachment to transfer B. Read More

Seroprevalence of Borrelia IgM and IgG Antibodies in Healthy Individuals: A Caution Against Serology Misinterpretations and Unnecessary Antibiotic Treatments.

Vector Borne Zoonotic Dis 2020 May 12. Epub 2020 May 12.

Department of Immunology, Second Faculty of Medicine, Charles University in Prague and University Hospital Motol, Prague, Czech Republic.

In Lyme disease, the interpretation of diagnostic assays is often misunderstood. Cross-reactions of Borrelia proteins with antigens from other bacterial species are well known. Therefore, to diagnose Lyme disease, the finding of positive IgM antibodies must be accompanied by objectively verified clinical signs and a history of a possible tick exposure. Read More
