Due to the life cycle of its vector, Lyme disease has known seasonal variation. However, investigations focused on children have been limited. Our objective was to evaluate the seasonality of pediatric Lyme disease in three endemic regions in the United States. We enrolled children presenting to one of eight Pedi Lyme Net participating emergency departments. Cases were classified based on presenting symptoms: early (single erythema migrans (EM) lesion), early-disseminated (multiple EM lesions, headache, cranial neuropathy, or carditis), or late (arthritis). We defined a case of Lyme disease by the presence of an EM lesion or a positive two-tier Lyme disease serology. To measure seasonal variability, we estimated Fourier regression models to capture cyclical patterns in Lyme disease incidence. While most children with early or early-disseminated Lyme disease presented during the summer months, children with Lyme arthritis presented throughout the year. Clinicians should consider Lyme disease when evaluating children with acute arthritis throughout the year.

Lyme disease is the most common vector-borne disease in the United States and is characterized by a bimodal age distribution and male predominance. We examined trends in reported cases during a 25-year period to describe changes in the populations most affected by Lyme disease in the United States. We examined demographic characteristics of people with confirmed cases of Lyme disease reported to the Centers for Disease Control and Prevention during 1992-2016 through the National Notifiable Diseases Surveillance System. We grouped cases into 5-year periods (1992-1996, 1997-2001, 2002-2006, 2007-2011, 2012-2016). We calculated the average annual incidence by age and sex and used incidence rate ratios (IRRs) to describe changes in Lyme disease incidence by age and sex over time. We converted patient age at time of illness into patient birth year to ascertain disease patterns according to birth cohorts. The incidence of Lyme disease in the United States doubled from 1992-1996 to 2012-2016 (IRR = 1.74; 95% CI, 1.70-1.78) and increased disproportionately among males; IRRs were 39%-89% higher among males than among females for most age groups. During the study period, children aged 5-9 years were most frequently and consistently affected. In contrast, the average age of adults with Lyme disease increased over time; of all adults, people born during 1950-1964 were the most affected by Lyme disease. Our findings suggest that age-related behaviors and susceptibilities may drive infections among children, and the shifting peak among adults likely reflects a probability proportional to the relative size of the baby boom population. These findings can inform targeted and efficient public health education and intervention efforts.

Clinical Signs And Symptoms

Lyme disease is the most common tick-borne illness in the United States. It occurs most commonly in areas that foster and harbor the deer tick. The number of reported cases of Lyme disease in the United States has increased steadily since 1982. The tick transmits an infection of the spirochete Borrelia burgdorferi that typically manifests as a localized skin lesion and erythema migrans. If left untreated, infection may lead to localized arthritis, heartblock, and/or disease of the nervous system. The diagnosis of Lyme disease is made primarily from clinical signs and symptoms that are suggestive of the disease. Treatment includes 10 to 27 days of antibiotics depending on stage of the disease. Vaccines for the prevention of Lyme disease are now licensed and the trend of increasing incidence of Lyme disease will likely be reversed.

The Impact

ABSTRACTErythema migrans is the most common clinical manifestation of Lyme disease, with concomitant subjective symptoms occurring in ∼65% of cases in the United States. We evaluated the impact of having been started on antibiotic treatment before study enrollment on 12 particular symptoms for 38 subjects with erythema migrans versus 52 untreated subjects. There were no significant differences in the frequency of having at least one symptom or in the symptom severity score on study entry. However, the frequency of having at least one symptom was significantly greater for those who had received <7 days of antibiotic treatment than for those who had been treated for ≥7 days (23/24 [95.8%] versus 8/14 [57.1%], P = 0.006). In addition, the percentage of subjects who were males was significantly lower among the group on treatment than among the untreated study subjects (13/38 [34.2%] versus 34/52 [65.4%], P = 0.005). In conclusion, based on these findings, combining untreated and treated groups of patients with erythema migrans for research study analyses may have limitations and, depending on the study objectives, might not be preferred. Additional studies are warranted to better understand the day-to-day impact of antibiotic treatment on the presence, type, and severity of symptoms in patients with early Lyme disease.

ABSTRACTIn the absence of erythema migrans, the basis for diagnosis of Lyme disease is the demonstration of an antibody response againstBorrelia burgdorferiin an appropriate clinical setting. The C6 enzyme-linked immunosorbent assay, based on the IR6 region of VlsE, has become widely used in both the United States and Europe. We mapped the antigenic epitopes of IR6 to a shorter sequence that is equivalent in sensitivity and specificity to the full-length IR6 25-residue peptide. In addition, we observed significant differences in sensitivity between serum panels (60 to 100%), indicating that the selection of the serum panels can shape the apparent overall sensitivity of the assay. Contrary to prior reports, the assay sensitivity is greater when the IR6 peptide is derived from the sequence of the same infectingBorreliagenospecies. Using our North American panels and the two panels obtained from European Lyme disease patients, we determined that the IR6 assay that is based on a single genospecies ofBorreliaspp. is not optimal for use as a universal diagnostic assay for Lyme disease.

Lyme disease is the most common vector-borne disease in the United States with Lyme arthritis becoming one of the most common symptoms of Lyme disease. It is imperative that school nurses become familiar with vector-borne disease and promptly consider Lyme arthritis to be contemplated as a differential diagnosis of a child presenting to the office with a limp and joint pain and swelling with no history of acute injury. The following article will discuss the overview, implications and management of Lyme arthritis in the school setting and includes a relevant IHP for school nurses to utilize in practice.

Lyme disease is the most common vector-borne disease in both the United States and Europe; however, its pathogenesis is incompletely understood. The studies described in this thesis aid in the elucidation of mechanisms regulating murine Lyme arthritis and may suggest mechanisms by which human Lyme disease is mediated. (1) We found that the chemokine KC is responsible for neutrophil recruitment and subsequent development of Lyme arthritis and carditis. This was the first study to describe an immunological regulatory mechanism mediating disease susceptibility to murine Lyme disease, as resistant mice (B6) produce less KC than susceptible (C3H/HeJ) mice and do not develop disease. (2) We found that metabolites produced via the COX-2 pathway are important for functional resolution and that resolution is likely mediated via the PGE2/EP2 axis. (3) We found that although dietary fish oil substitution leads to a global shift in eicosanoid production (from AA/LA-derived eicosanoids to EPA/DHA-derived eicosanoids) and promotes antiinflammatory prostaglandin production, disease severity is not altered. (4) We found that eicosanoid production throughout the course of autoantibody-drive K/BxN serum-transfer arthritis differs significantly from that seen during Lyme arthritis and that patterns of eicosanoid expression reflect the severity and kinetics of each type of arthritis. These studies aid in understanding the immunological mechanisms regulating the occurrence and severity of murine Lyme arthritis.

Introduction and Definitions Lyme borreliosis (Lyme disease) is a systemic infection caused by a spirochete, Borrelia burgdoferi. It is the most common vector-borne disease in the United States. Lyme disease was first described in Lyme, Connecticut (hence its name), where a cluster of children who had unexplained arthritis first were brought to medical attention by one of their parents. Investigation of this "epidemic" of arthritis led to the description of Lyme arthritis and ultimately to the discovery of its bacterial etiology. The clinical manifestations of Lyme borreliosis are protean; this, coupled with the practical difficulties of confirming the diagnosis in many patients, has led to many misconceptions about Lyme disease. Indeed, there is much we do not know about the disease, which was only recognized in the US as a distinct entity slightly more than 15 years ago, and the cause of which was first identified only about 10 years ago. Epidemiology ECOLOGY AND TRANSMISSION Borrelia burgdorferi is transmitted by ticks of the Ixodid species. In the US, the common vectors are Ixodes dammini (the deer tick), reported to be the same species as I scapularis, in the Northeast and the Midwest and I pacificus (the western black-legged tick) on the Pacific Coast. Ixodes ticks are much smaller than the common wood tick; the nymphal Ixodes tick is about the size of a pencil point (1 to 2 mm).

Knee Effusion

A 13-year-old female recreational soccer player presented with spontaneous left knee effusion approximately 2 weeks after the start of soccer season. Radiographic imaging was negative, and a complete blood count identified an increase in inflammatory markers. Additional two-tier testing confirmed a Lyme disease diagnosis, which was unusual for an athlete residing in the southeast region of the United States. The presentation of knee effusion, and subsequently Lyme arthritis, is a common clinical manifestation of late-stage Lyme disease. Early recognition of this infection and prompt treatment by a variety of specialists reduce the severity or chronicity of symptoms.
