Challenges in the Diagnosis and Treatment of Lyme Disease
AbstractPurpose of ReviewSince recognition in 1975, Lyme disease has become the most common vector-borne illness in North America and Europe. The clinical features are well-characterized and treatment is usually curative, but misperceptions about morbidity persist. The purpose of this review is to examine advances in the diagnosis and treatment of Lyme disease, as well as ongoing management challenges.Recent FindingsIt is useful to recognize that Lyme disease occurs in stages, with early- and late-stage disease. Clinical expression is in part determined by Borrelial variability. For example, some strains ofBorrelia burgdorferi, the causative organism in North America, are particularly arthritogenic. Most patients with early Lyme disease can be cured with a single course of oral antibiotic therapy, in contrast to some patients with Lyme arthritis, a late-stage manifestation, who are more antibiotic refractory and require other treatment strategies.SummarySuccessful treatment of Lyme disease begins with successful diagnosis and with an understanding of the emergence, clinical features, and impact of Lyme disease over the past half century.
Pathogen specific antibody responses need to be tightly regulated to generate protective but limit self-reactive immune responses. While loss of humoral tolerance has been associated with microbial infections, the pathways involved in balancing protective versus autoreactive antibody responses in humans are incompletely understood. Studies in classical mouse model systems have provided evidence that balancing of immune responses through inhibitory receptors is an important quality control checkpoint. Genetic differences between inbred mouse models and the outbred human population and allelic receptor variants not present i...

Lyme borreliosis is the most prevalent tick-borne disease in the northern hemisphere.1 Over the last decades, marked increases in the incidence of Lyme borreliosis have been reported in several Western European countries and the United States (US), with substantial impact on public health.2 –6 Erythema migrans is the most common early skin manifestation of the disease, and responds well to antibiotic treatment.7 However, erythema migrans is often not observed preceding disseminated Lyme borreliosis manifestations such as neuroborreliosis, Lyme arthritis and Lyme carditis.

(Virginia Tech) With a $661,216 grant from the Steven&Alexandra Cohen Foundation, Brandon Jutras, an assistant professor of biochemistry in the Virginia Tech College of Agriculture and Life Sciences, will study Lyme arthritis, including the cellular component that contributes to it.
(Washington State University) The next time a tick feeds on you, Washington State University researchers hope to make sure persistent arthritis caused by Lyme disease doesn't linger for a lifetime.
Purpose of review Lyme disease is an important, vector-borne infection found throughout the temperate Northern hemisphere. The disease causes rash, acute systemic illness, and in some untreated patients, inflammatory arthritis. This review examines the emergence, clinical features and management of early Lyme disease and Lyme arthritis. Recent findings There has been continuing progress in characterizing the clinical manifestations, diagnostic testing and treatment of Lyme disease. Almost all patients with early Lyme disease can be cured with antibiotic treatment. In most cases, Lyme arthritis also responds to antibio...

(Natural News) Lyme disease is one of the most common vector-borne diseases in the US. The CDC reports that around 30,000 Americans get infected by Lyme every year. However, other data gathering methods suggest that this number can rise to 300,000 cases each year. Because of the rising number of Lyme disease cases, scientists have...
NEW YORK (Reuters Health)—In Lyme disease-endemic areas, a C6 peptide enzyme immunoassay (EIA) test may help guide initial management of children with acute arthritis, an observational study suggests.1 “Children with Lyme disease frequently present to the emergency department with an inflamed joint,” Lise Nigrovic, MD, MPH, of Boston Children’s Hospital tells Reuters Health by email....
