The Lyme Disease Polymerase Chain Reaction Test Has Low Sensitivity.

The Lyme PCR is a direct detection test, but has not been rigorously evaluated in children undergoing evaluation for acute Lyme disease. We performed a six-center prospective cohort study of children aged 1 to 21 years undergoing acute evaluation for Lyme disease. For this planned secondary analysis, we limited our cohort to children undergoing evaluation for Lyme disease who had any Lyme PCR test obtained by a treating clinician (blood, synovial fluid, or cerebrospinal fluid). We defined a case of Lyme di...

Updated CDC Recommendation for Serologic Diagnosis of Lyme Disease.

Lyme disease is a tickborne zoonosis for which serologic testing is the principal means of laboratory diagnosis. In 1994, the Association of State and Territorial Public Health Laboratory Directors, CDC, the Food and Drug Administration (FDA), the National Institutes of Health (NIH), the Council of State and Territorial Epidemiologists, and the National Committee for Clinical Laboratory Standards convened the Second National Conference on Serologic Diagnosis of Lyme Disease (1).

Somatic symptom disorder should be suspected in children with alleged chronic Lyme disease.

We report a case series of seven children admitted to a tertiary level pediatric ward for long-lasting physical symptoms with a previous diagnosis of chronic Lyme disease. In these children, medical history and clinical features were strongly suggestive of a psychopathological disorder, mainly a somatic symptom disorder. What is Known: • There is an increasing number of diagnoses of chronic Lyme disease both in North America and in Europe. Adults receive this diagnosis to explain chronic physical complain...

The continued rise of Lyme disease in Ontario, Canada: 2017.

Lyme disease is an infection caused by the spirochete and, in most of North America, is transmitted by the blacklegged tick . Climate change has contributed to the expansion of the geographic range of blacklegged ticks in Ontario, increasing the risk of Lyme disease for Ontarians.

Postoperative Lyme Arthritis in the Orthopaedic Patient.

Lyme disease is the most common tick-borne illness in North America and Europe, and Lyme arthritis is a frequent late-stage manifestation in the United States. However, Lyme arthritis has rarely been reported as a postoperative complication.

Measurement of organ-specific and acute-phase blood protein levels in early Lyme disease.

Lyme disease results from infection of humans with the spirochete Borrelia burgdorferi. The first and most common clinical manifestation is the circular, inflamed skin lesion referred to as erythema migrans; later manifestations result from infections of other body sites. Laboratory diagnosis of Lyme disease can be challenging in patients with erythema migrans because of the time delay in the development of specific diagnostic antibodies against Borrelia. Reliable blood biomarkers for the early diagnosis of...

Appropriate laboratory testing in Lyme disease.

Testing for Lyme disease is challenging and if done incorrectly can lead to unnecessary treatment. To interpret serologic test results, first assess the patient's pretest probability of infection based on the probability of exposure and clinical findings. Two-tiered testing remains the gold standard in diagnosing Lyme disease, although new guidelines may be published soon.

Lyme Arthritis in a Military Dependent Child transferred from Japan.

Lyme arthritis is the most common manifestation of late Lyme disease in children. Lyme disease is known to be endemic to Japan, but is rarely diagnosed. We report the identification and successful treatment of an adolescent male with Lyme arthritis who recently relocated with his family from a US Military base in Japan to Virginia. This case highlights the importance of obtaining a travel history from military members and their families who frequently relocate due to military orders. Military medical provid...

Epidemiological study of Lyme disease in Bulgaria.

Lyme disease (Lyme borreliosis) is a transmissible infection, common in the temperate climate zones. It is caused by a group of spirochetal bacteria known as Borrelia burgdorferi sensu lato complex. The aim of the present work was to investigate the incidence rate of borreliosis in different regions of Bulgaria and to identify possible risk factors for its occurrence.

Prevalence of Lyme Disease Attributable to Military Service at the USMA, West Point NY: FY2016-2018.

Lyme disease incidence rates have steadily increased since its official recognition in 1975. Since exposure to Lyme is associated with activities conducted in and around tick-habitats including tall grass, shrubs, deciduous forest, and leaf litter, it has been suggested that service members, who are thought to spend higher amounts of time in these habitats due to training requirements, may have higher risk for exposure. Specifically, this study looks at service member and family member exposure to Ixodes sc...

Lipid Profiles in Lyme Borreliosis: A Potential Role for Apheresis?

Dyslipidemia and dyslipoproteinemia are common causes of metabolic and cardiovascular diseases. On the other hand, intracellular bacteria, such as , utilize host lipids to survive and disseminate within the host. Recent data suggest that elevated lipids are a contributing factor to the maintenance and severity of Lyme disease and its complications. Here we review and discuss the role of lipids in Borreliosis and report on a pilot trial to examine the potential roles of circulating lipids and lipoproteins in...

Unconventional diagnostic tests for Lyme borreliosis: a systematic review.

Lyme borreliosis (LB) diagnosis currently relies mainly on serological tests and sometimes polymerase chain reaction or culture. However, other biological assays are being developed to try to improve Borrelia-infection diagnosis and/or monitoring.

Peridomestic and community-wide landscape risk factors for Lyme disease across a range of community contexts in Pennsylvania.

Land use and forest fragmentation are thought to be major drivers of Lyme disease incidence and its geographic distribution. We examined the association between landscape composition and configuration and Lyme disease in a population-based case control study in the Geisinger health system in Pennsylvania. Lyme disease cases (n = 9657) were identified using a combination of diagnosis codes, laboratory codes, and antibiotic orders from electronic health records (EHRs). Controls (5:1) were randomly selecte...

Lyme Neuroborreliosis in Children: Etiology and Comparison of Clinical Findings of Lyme Neuroborreliosis Caused by Borrelia garinii and Borrelia afzelii.

Information on the etiology of Lyme neuroborreliosis (LNB) in children in Europe and the influence of Borrelia burgdorferi sensu lato species isolated from cerebrospinal fluid (CSF) on clinical presentation of LNB in children are limited.

Evaluating the Potential Misuse of the Lyme Disease Surveillance Case Definition.

Laboratory Blood-Based Testing for Non-Lyme Disease Tick-Borne Infections at a National Reference Laboratory.

We evaluated trends in non-Lyme disease tick-borne disease (NLTBI) testing at a national reference laboratory.

BBE31 from the Lyme disease agent Borrelia burgdorferi, known to play an important role in successful colonization of the mammalian host, shows the ability to bind glutathione.

Lyme disease is a tick-borne infection caused by Borrelia burgdorferi sensu lato complex spirochetes. The spirochete is located in the gut of the tick; as the infected tick starts the blood meal, the spirochete must travel through the hemolymph to the salivary glands, where it can spread to and infect the new host organism. In this study, we determined the crystal structures of the key outer surface protein BBE31 from B. burgdorferi and its orthologous protein BSE31 (BSPA14S_RS05060 gene product) from B. sp...

Post-treatment Lyme disease symptoms score: Developing a new tool for research.

Some patients have residual non-specific symptoms after therapy for Lyme disease, referred to as post-treatment Lyme disease symptoms or syndrome, depending on whether there is functional impairment. A standardized test battery was used to characterize a diverse group of Lyme disease patients with and without residual symptoms. There was a strong correlation between sleep disturbance and certain other symptoms such as fatigue, pain, anxiety, and cognitive complaints. Results were subjected to a Logistic Reg...

A Neurologist's View of Lyme Disease and Other Tick-Borne Infections.

Tick-borne infections-including tick-borne encephalitis viruses, represented in the United States by rare infections with Powassan and deer tick viruses, and more often Lyme disease-are of increasing importance to neurologists. Lyme neuroborreliosis (LNB) causes all or part of a triad including meningitis, radiculoneuritis, and cranial neuritis. Rarely, parenchymal brain and spinal cord involvement occur, with focal findings on examination and magnetic resonance imaging (MRI). LNB diagnosis requires plausib...

Identifying Predictive Factors of Pediatric Septic Arthritis of the Knee in a Lyme Endemic Area.

Septic arthritis of the knee in the pediatric patient is a diagnosis that requires prompt identification and treatment. The purpose of this study was to identify clinical and laboratory parameters that allow differential diagnosis of septic arthritis from non-septic arthritis in children.

Lyme Carditis: A Rare Presentation of Sinus Bradycardia Without Any Conduction Defects.

Lyme carditis is a rare cardiac manifestation of Lyme disease that occurs when bacterial spirochetes infect the pericardium or myocardium triggering an inflammatory response. The most common electrocardiogram (EKG) findings in these patients include atrioventricular (AV) conduction abnormalities (first, second, and third degree heart block). A 56-year-old male with a history of hypothyroidism, from the Northeastern region of the United States, presented to the emergency department with lightheadedness and c...

Prospective comparison of two enzyme-linked immunosorbent spot assays for the diagnosis of Lyme neuroborreliosis.

Commercial cellular tests are used to diagnose Lyme borreliosis, but studies on their clinical validation are lacking. This study evaluated the utility of an in-house and a commercial enzyme-linked immunosorbent spot (ELISpot) assay for the diagnosis of Lyme neuroborreliosis. Prospectively, peripheral blood mononuclear cells (PBMCs) were isolated from patients and controls and analysed by using an in-house Borrelia ELISpot assay and the commercial LymeSpot assay. Borrelia burgdorferi B31 whole cell lysate a...

The role of genetics in the pathogenesis and diagnosis of type 1 Von Willebrand disease.

Von Willebrand disease (VWD) is a common bleeding disorder, but diagnosis of VWD is challenging, particularly with type 1 VWD. Although most clinicians use specific tests of von Willebrand factor (VWF) activity to classify patients with VWD, genetic testing for VWF defects is another potential method of diagnosis.

The establishment and clinical evaluation of a novel, rapid, no-wash one-step immunoassay for the detection of dengue virus non-structural protein 1.

Dengue fever is a highly endemic arthropod-borne viral disease in the tropical and sub-tropical countries and is rapidly becoming a global threaten. Diagnosis has been conducted by either traditional serological methods or molecular biological techniques. However, these methods are either labor-intensive, time-consuming or with multiple steps, which are not suitable for high throughput detection of large quantity of samples. In the current study, a novel, rapid, no-wash one-step amplified luminescent proxim...

SERS-based immunoassay using gold-patterned array chips for rapid and sensitive detection of dual cardiac biomarkers.

Cardiac troponin I (cTnI) and creatine kinase-MB (CK-MB) are important diagnostic biomarkers for acute myocardial infarction (AMI). Many efforts have been undertaken to develop highly sensitive detection methods for the quantitative analysis of these dual targets. However, current immunoassay methods are inadequate for accurate measurement of cTnI and CK-MB, due to their limited detection sensitivity. Thus, there is still an urgent demand for a new technique that will enable ultrahigh sensitive detection of...
