This study evaluates overall incidence rates and demographic, seasonal, and geographic trends of first Lyme disease diagnosis among 384,652 Maryland Medicaid members enrolled from July 2004-June 2011 and represents the first analysis of claims data from publicly insured individuals.
Patients with Post-treatment Lyme Disease Syndrome (PTLDS) commonly complain of cognitive symptoms. The study found, in subsets of PTLDS patients, objective evidence of cognitive decline in verbal memory and processing speed, cognitive impairment, and sub-optimal engagement with testing.
To our knowledge, this is the first study to explore factors which may contribute to a delay in diagnosis and treatment of Lyme disease. We identified distinct, potentially modifiable risk factors between onset of first Lyme disease symptoms and treatment. Targeting these drivers may reduce time to diagnosis and treatment and reduce the occurrence of late-stage Lyme disease complications.
This is the first study to examine and quantify sleep quality in the context of well-defined early Lyme disease (LD) and post-treatment Lyme disease syndrome (PTLDS). The findings provide support that sleep disturbance should be considered in the clinical picture of individuals with LD. Sleep quality may particularly be poor and associated with the pain experience for individuals with PTLDS. Future research will need to validate and expand upon these findings to investigate sleep quality in individuals exposed to LD who are not well-defined and/or ideally treated.
This study shows that well-validated symptom surveys could be used by doctors to identify suggestive symptom patterns that could lead to the diagnosis of PTLDS.
Symptoms may persist after antibiotic treatment of early Lyme disease. The objective of this study was to investigate associations between post-treatment Lyme disease syndrome and biomarkers of inflammation during early Lyme disease.
