BI160: Development of Vaccines to Infectious Diseases

HISTORY

 

Lyme disease is a cyclic disease which has chronic, multi-systemic, neuropsychiatric manifestations. [1] It causes functional, chemical, and structural changes to the brain and alters almost every organ system of the body. It is caused by the spirochete, Borrelia burgdorferi, which is transmitted to humans through the bite of infected deer ticks [2]. In 1975, Lyme Disease was classified as a new disease in response to approximately 50 cases of pediatric arthritis in the town of Lyme, Connecticut. These cases were originally diagnosed as “Lyme Arthritis,” until the unique symptomology indicated a different etiology. This was not the first reported incidence of Lyme, as it been documented as early as 1883 by Alfred Buchwald, but it paved the way for further research into the disease.

Since 1975, the prevalence of the disease has increased many fold, but so has our understanding of it. The determination of the causative agent of the disease, Borrelia burgdorferi, and its vector, the Ixodes tick has led to the development of various medical interventions and vaccine approaches. As our understanding of the disease deepens, the prospects for vaccine development become more numerous and more promising.

Timeline of important events in the history of Lyme Disease
Year
Event
1883
The first recorded case of Lyme Disease is described by Alfred Buchwald. He described it as a degenerative skin disorder now known as ACA (acrodermatitis chronica atorphicans).
1909
Arvid Afzelius presents his research on expanding ring like lesion (erythema migrans) associated with what would become known as Lyme Disease.
1921
Arvid Afzelius publishes his work and speculates on the origin of the disease as the Ixodes Scapularis tick and connects the disease with joint problems.
1922
The disease is found to be associated with neurological problems.
1930
The disease is found to also cause psychiatric problems.
1934
Appearance of EM or ACA is associated with benign lymphocytomas.
Arthritic symptoms are reported in connection with the disease.
