Estimation of cumulative number of post-treatment Lyme disease cases in the US, 2016 and 2020

Lyme disease (LD) is an infectious multi-system illness caused by the bacterial genus Borrelia and spread by bites of infected ticks. Although most patients are successfully treated by timely antibiotic therapy, ...

Authors: Feng J, Li T, Yee R, Yuan Y, Bai C, Cai M, Shi W, Embers M, Brayton C, Saeki H, Gabrielson K, Zhang Y Abstract Although most patients with Lyme disease can be cured with a 2-4 week antibiotic therapy, about 10-20% of patients continue to suffer prolonged persistent symptoms, a condition called post-treatment Lyme disease syndrome (PTLDS). The cause for PTLDS is unclear and hotly debated. Borrelia burgdorferi develops morphological variants under stress conditions but their significance is not clear. Here we isolated the biofilm-like microcolony (MC) and planktonic (spirochetal form and round body) (SP) var...

Authors: Weiss T, Zhu P, White H, Posner M, Wickiser JK, Washington MA, Barnhill J Abstract Lyme disease is a continuing threat to military personnel operating in arboriferous and mountainous environments. Here we present the case of a 24-year-old Second Lieutenant, a recent graduate from the United States Military Academy, with a history of Lyme disease who developed recurrent knee effusions following surgery to correct a hip impingement. Although gonococcal arthritis was initially suspected from preliminary laboratory results, a comprehensive evaluation contradicted this diagnosis. Despite antibiotic therapy, asp...

Abstract Borrelia burgdorferi is the causative agent of Lyme borreliosis. Antibiotic therapy of early acute infection is effective for most patients, but 10-20% go on to develop Post-Treatment Lyme Disease Syndrome. The nature of PTLDS remains unknown, but currently approved antibiotics for treatment of Lyme disease do not appear to impact these symptoms after they have developed. We reason that minimizing the time the pathogen interacts with the host will diminish the probability of developing PTLDS, irrespective of its nature. This calls for an efficient eradication of the pathogen during acute infection. In sea...

Publication date: Available online 15 June 2017 Source:Microbes and Infection Author(s): Jorge Cervantes Lyme disease is a zoonosis caused by infection with Borrelia burgdorferi (Bb). A great amount of research has attempted to elucidate the mechanisms by which Bb causes inflammation and chronic symptomatology in some patients. Patients often seek unconventional treatments that lack scientific evidence, as medical care is unable to effectively explain and treat their illness. Bb-DNA can persist for long periods of time in some individuals, even after antibiotic therapy. Herein, scientific rationale is presented for a new ...

Conclusions: During active infection, microRNA expression in SF reflected an immune response associated with bacterial killing, whereas in post‐infectious LA, microRNA expression in SF and synovial tissue reflected chronic inflammation, synovial proliferation, and breakdown of wound repair processes, showing that the nature of the arthritis was altered after spirochetal killing.

Authors: Brás A, Marques N, Santiago B, Matos A, Moreira F Abstract Neurological manifestations of Lyme disease are reported in 3% - 12% of patients, with the most common form of presentation being meningoradiculitis. Other symptoms involving the central nervous system, such as myelitis or encephalitis, are rare (

Purpose of review: Lyme disease is a multistage and multisystem disease. Neurological manifestations [termed Lyme neuroborreliosis (LNB)] occur in about 10% of patients with Lyme disease. Diagnostics and treatment of early and late LNB are widely established. However, the management of persistent symptoms is still fraught with controversies, and therefore is the focus of this review. Recent findings: The incidence of Lyme disease seems to be much higher than previously assumed. Laboratory methods (namely serological tests) are essential for diagnosing LNB, but only when performed according to the guidelines of scientific ...

CONCLUSION: Foresters and farmers are exposed to B. burgdorferi and A. phagocytophilum coinfection in the study area. Therefore, it is probable that these pathogens may severely interfere with the clinical course of Lyme borreliosis. PMID: 28035112 [PubMed - in process]

Abstract Lyme borreliosis is caused by Borrelia burgdorferi sensu lato infection, which responds well to antibiotic therapy in the overwhelming majority of cases. However, despite adequate antibiotic treatment some patients report persisting symptoms which are commonly summarised as post-treatment Lyme disease syndrome (PTLDS). In 2005, the Swiss Society of Infectious Diseases published a case definition for PTLDS. We aimed to review the scientific literature with a special emphasis on the last 10 years, questioning whether the definitions from 2005 are still valid in the light of current knowledge. Furthermore, w...

Abstract There is no convincing evidence that classic Lyme disease occurs in Australia, nor is there evidence that the causative agent, Borrelia burgdorferi, is found in Australian animals or ticks. Lyme disease, however, can be acquired overseas but diagnosed in Australia; most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. Despite the lack of evidence that Lyme disease can be acquired in Australia, growing numbers of patients, their supporters, and some politicians demand diagnoses and treatment according to the protocols of the "chronic Lyme disease" sch...
