Abstract

Insights

Early Lyme disease (Borrelia burgdorferi) often involves subclinical hepatitis, with nearly 30% of patients showing liver function abnormalities. This highlights a commonly overlooked aspect of early infection.

Area of Science:

  • Infectious Diseases
  • Hepatology
  • Epidemiology

Background:

  • Lyme disease, a tick-borne illness caused by Borrelia burgdorferi, can affect multiple organ systems.
  • Hepatic involvement in early Lyme disease is often underreported in medical literature.

Purpose of the Study:

  • To investigate the prevalence and characteristics of hepatic dysfunction in patients presenting with early Lyme disease.
  • To document clinical and laboratory findings associated with liver abnormalities in this patient cohort.

Main Methods:

  • A case series design was employed, analyzing data from 73 patients diagnosed with erythema migrans.
  • Patients were recruited from family physician offices in an endemic area for Lyme disease.
  • Liver function tests were conducted as the primary outcome measure.

Main Results:

  • Twenty patients (27%) exhibited abnormal liver function tests, with elevated gamma-glutamyltransferase being the most frequent finding.
  • A low percentage of patients (9%) had positive Lyme disease titers via ELISA, indicating early-stage infection.
  • Detailed clinical and laboratory data for all patients were recorded and analyzed.

Conclusions:

  • Subclinical hepatitis is a frequent, yet often unrecognized, manifestation of early Lyme disease.
  • These findings suggest that liver function should be considered in the comprehensive evaluation of early Lyme disease presentations.
