The pathologist's view of Lyme disease

Area of Science:

• Infectious Diseases
• Pathology
• Immunobiology

Background:

• Lyme disease is a multisystem illness caused by Borrelia burgdorferi.
• Transmission occurs primarily through Ixodid tick bites.
• The clinical and pathological spectrum of Lyme disease is expanding.

Purpose of the Study:

• To review the pathology and histopathologic manifestations of Lyme disease in humans.
• To describe the pathological changes associated with erythema migrans, neurological, cardiac, and arthritic manifestations.
• To highlight the potential of animal models in understanding Lyme disease immunobiology.

Main Methods:

• Review of existing literature on Lyme disease pathology.
• Description of pathological changes at different disease stages.
• Discussion of immunobiological interactions of Borrelia burgdorferi.

Main Results:

• Pathological changes occur in the skin (erythema migrans), nervous system, heart, and joints.
• The understanding of Lyme disease pathology continues to evolve.
• Experimental animal models offer insights into disease mechanisms.

Conclusions:

• Lyme disease presents with diverse pathological findings across multiple organ systems.
• Further research, including studies in animal models, is crucial for a comprehensive understanding of Lyme disease immunobiology and pathology.
