Clinical spectrum of Lyme disease
AbstractLyme disease (borreliosis) is one of the most common vector-borne diseases worldwide. Its incidence and geographic expansion has been steadily increasing in the last decades. Lyme disease is caused byBorrelia burgdorferi sensu lato, a heterogeneous group of which three genospecies have been systematically associated to Lyme disease:B. burgdorferi sensu strictoBorrelia afzelii andBorrelia garinii. Geographical distribution and clinical manifestations vary according to the species involved. Lyme disease clinical manifestations may be divided into three stages. Early localized stage is characterized by erythema migrans in the tick bite site. Early disseminated stage may present multiple erythema migrans lesions, borrelial lymphocytoma, lyme neuroborreliosis, carditis, or arthritis. The late disseminated stage manifests with acordermatitis chronica atrophicans, lyme arthritis, and neurological symptoms. Diagnosis is challenging due to the varied clinical manifestations it may present and usually involves a two-step serological approach. In the current review, we present a thorough revision of the clinical manifestations Lyme disease may present. Additionally, history, microbiology, diagnosis, post-treatment Lyme disease syndrome, treatment, and prognosis are discussed.

Borreliosis (Lyme disease) is a spirochetal disease caused by the species complex ofBorrelia burgdorferi transmitted byIxodes spp. ticks. Recorded to be the most common tick ‐borne disease in the world, the last two decades have seen an increase in disease incidence and distribution, exceeding 360 000 cases in Europe alone. If untreated, infection may cause skin symptoms, arthritis, and neurological or cardiac complications. Borrelia spirochetes have developed strate gies to evade the mammalian host immune system. These include the complement system, which is an important first‐line defense mechanism against...
In conclusion, These results reveal new possibilities for the treatment of Lyme arthritis. PMID: 32829087 [PubMed - as supplied by publisher]

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.
