Evaluation of the Epitogen Lyme Detect IgG ELISA: a novel peptide multiplexing approach.

Microbiol Spectr

October 2024

EpitogenX Ltd, Foresterhill Health Campus, Aberdeen, United Kingdom.

Article Synopsis
  • Lyme Borreliosis (LB), or Lyme disease, is increasingly concerning due to its severe health risks from untreated cases, often diagnosed too late with current tests having low sensitivity.
  • A new diagnostic test, the Epitogen Lyme Detect IgG ELISA, was validated in this study using 220 serum samples to assess sensitivity and specificity against the standard LIAISON Borrelia IgG test.
  • The Epitogen test showed comparable performance for late stages of LB and significantly higher sensitivity for early suspected cases, indicating it could improve early and accurate diagnosis of Lyme disease.

Article Synopsis
  • Lyme borreliosis, caused by the Borrelia burgdorferi spirochete, is a complex infection primarily indicated by erythema migrans on the skin.
  • A study examining 509 patients over nine years aimed to explore skin manifestations and their impact on diagnosis and treatment, revealing various clinical presentations beyond just erythema migrans.
  • Findings showed that while erythema migrans is a key marker, other skin conditions like "pink borreliosis stretch marks" and "borreliosis palms or soles" are important for diagnosing chronic borreliosis.

Lyme Disease: An Overview.

Indian Dermatol Online J

February 2023

Department of Dermatology, Venereology and Leprosy, Dr. Radhakrishnan Government Medical College, Hamirpur, Himachal Pradesh, India.

Article Synopsis
  • Lyme disease is caused by a spirochete and is primarily transmitted through infected tick bites, with symptoms like an erythema migrans rash indicating early infection.
  • The disease incidence is rising due to factors like reforestation and increased human interaction with tick habitats, and late stages can involve severe issues requiring complicated treatment approaches.
  • Diagnosis typically involves a two-step serological testing process, and while oral doxycycline is the preferred treatment, prevention remains crucial as there is no vaccine and past infections do not provide lasting immunity.

High-risk groups for alpha-gal sensitization.

Allergol Select

August 2023

Department of Dermatology and Allergy Biederstein, Faculty of Medicine, Technical University of Munich, Munich, Germany.

Article Synopsis
  • The study examines sensitization to the oligosaccharide alpha-gal, which can cause allergic reactions from tick bites, comparing three groups with varying tick exposure.
  • It analyzed specific IgE levels in 485 patients with Lyme disease and a control group of 200 individuals with less tick exposure, alongside 232 hunters and forest workers frequently exposed to ticks.
  • Results indicate a higher prevalence of alpha-gal sensitization in tick-exposed individuals, especially among hunters and forest workers, suggesting increased tick contact may lead to sensitization over time.

University of Zürich, Institute for Epidemiology, Biostatistics and Prevention, WHO Collaborating Centre for Travellers' Health, Department of Global and Public Health, MilMedBiol Competence Centre, Zürich, Switzerland.

Article Synopsis
  • - **Tick-Borne Infections:** The study focuses on the prevalence of Spotted fever group Rickettsiae (SFG) infections in humans in Switzerland, noting that these infections are often underrecognized after tick bites. - **Testing Results:** Among 121 patients, 53.7% tested positive for IgG antibodies, with higher levels seen in late-stage Lyme disease compared to early stages; fatigue, headache, and muscle pain were linked to higher IgG prevalence. - **Need for Further Research:** The findings highlight a gap in understanding SFG rickettsiae's role in post-tick bite symptoms, suggesting the need for more research to confirm its impact and the necessity for treatment options.

[CME: Neuroborreliosis].

Praxis (Bern 1994)

October 2022

Innere Medizin, Kantonsspital Graubünden, Schweiz.

Article Synopsis
  • Lyme disease is the most common tick-borne infection in Europe, caused by bacteria from the Borrelia complex, and initially appears as a skin infection known as Erythema migrans.
  • If untreated, it can lead to serious complications like neurological Lyme disease, Lyme carditis, and Lyme arthritis, with neuroborreliosis affecting 3-15% of patients, potentially causing polyradiculitis or meningitis.
  • Treatment for neuroborreliosis typically involves antibiotics such as doxycycline, ceftriaxone, or penicillin G, while prevention focuses on reducing tick exposure, and a vaccine is being developed in Europe.

Article Synopsis
  • A retrospective study assessed the effectiveness of nine serological assays for diagnosing Lyme borreliosis (LB) using sera from 74 LB cases and 122 controls.
  • Sensitivity of these tests varied significantly, with higher detection rates in cases like Lyme neuroborreliosis compared to early Lyme cases, and overall performance was adequate across both early and late forms of LB.
  • The study concluded that while serological assays are essential for diagnosing LB, IgM testing did not enhance diagnostic accuracy beyond IgG testing, and a two-tier testing approach is recommended to minimize false positives.

Lancet Reg Health Eur

July 2021

National Institute for Public Health and the Environment (RIVM), Center for Infectious Disease Control, P.O. Box 1, 3720 BA, Bilthoven, Netherlands.

Article Synopsis
  • A large prospective study investigated long-lasting symptoms in adults treated for Lyme borreliosis (LB), comparing these patients to general population and tick-bite controls.
  • The study found that 27.2% of LB patients experienced persistent symptoms, notably higher than the 21.2% and 23.3% found in the general population and tick-bite groups, respectively.
  • These persistent symptoms included more severe fatigue, cognitive impairment, and pain among erythema migrans patients compared to those without LB, suggesting an association between LB and lingering health issues in some patients.
