RESUMEN

BACKGROUND: Lyme disease after a tick bite often presents as erythema migrans, yet less frequent variants of this disease, such as Borrelia lymphocytoma, multiple erythema migrans and neuroborreliosis, are also seen occasionally. CASE PRESENTATION: We report a case of a tick-bitten child who first presented with an indistinct macular erythema around the left eye and a more distinct macular erythema on and around the left ear. The next day, she developed a facial palsy. INTERPRETATION: The case was interpreted as facial multiple erythema migrans and Borrelia lymphocytoma on the ear, followed by neuroborreliosis. The diagnosis of lymphocytoma was made from clinical findings and PCR of skin biopsy. She recovered quickly after intravenous ceftriaxone and is now healthy.

RESUMEN

Lyme disease results from infection of humans with the spirochete Borrelia burgdorferi. The first and most common clinical manifestation is the circular, inflamed skin lesion referred to as erythema migrans; later manifestations result from infections of other body sites. Laboratory diagnosis of Lyme disease can be challenging in patients with erythema migrans because of the time delay in the development of specific diagnostic antibodies against Borrelia. Reliable blood biomarkers for the early diagnosis of Lyme disease in patients with erythema migrans are needed. Here, we performed selected reaction monitoring, a targeted mass spectrometry-based approach, to measure selected proteins that (1) are known to be predominantly expressed in one organ (i.e., organ-specific blood proteins) and whose blood concentrations may change as a result of Lyme disease, or (2) are involved in acute immune responses. In a longitudinal cohort of 40 Lyme disease patients and 20 healthy controls, we identified 10 proteins with significantly altered serum levels in patients at the time of diagnosis, and we also developed a 10-protein panel identified through multivariate analysis. In an independent cohort of patients with erythema migrans, six of these proteins, APOA4, C9, CRP, CST6, PGLYRP2, and S100A9, were confirmed to show significantly altered serum levels in patients at time of presentation. Nine of the 10 proteins from the multivariate panel were also verified in the second cohort. These proteins, primarily innate immune response proteins or proteins specific to liver, skin, or white blood cells, may serve as candidate blood biomarkers requiring further validation to aid in the laboratory diagnosis of early Lyme disease.

RESUMEN

BACKGROUND: After antibiotic treatment of Lyme borreliosis, a subset of patients report persistent symptoms, also referred to as post-treatment Lyme disease syndrome. The reported prevalence of persistent symptoms varies considerably, and its pathophysiology is under debate. The LymeProspect study has been designed to investigate the prevalence, severity, and a wide range of hypotheses on the etiology of persistent symptoms among patients treated for Lyme borreliosis in the Netherlands. METHODS: LymeProspect is a prospective, observational cohort study among adults with proven or probable Lyme borreliosis, either erythema migrans or disseminated manifestations, included at the start of antibiotic treatment. During one year of follow-up, participants are subjected to questionnaires every three months and blood is collected repeatedly during the first three months. The primary outcome is the prevalence of persistent symptoms after treatment, assessed by questionnaires online focusing on fatigue (CIS, subscale fatigue severity), pain (SF-36, subscale pain) and neurocognitive dysfunction (CFQ). Potential microbiological, immunological, genetic, epidemiological and cognitive-behavioral determinants for persistent symptoms are secondary outcome measures. Control cohorts include patients with long-lasting symptoms and unconfirmed Lyme disease, population controls, and subjects having reported a tick bite not followed by Lyme borreliosis. DISCUSSION: This article describes the background and design of the LymeProspect study protocol. This study is characterized by a prospective, explorative and multifaceted design. The results of this study will provide insights into the prevalence and determinants of persistent symptoms after treatment for Lyme borreliosis, and may provide a rationale for preventive and treatment recommendations. TRIAL REGISTRATION: NTR4998 (Netherlands Trial Register). Date of registration: 13 February 2015.

RESUMEN

Lyme disease is an emerging problem in Poland. Analysis has been undertaken of the medical documentation of 86 patients hospitalized in the Infectious Diseases Department, University Hospital in Cracow in 2013-2016, suspected of Lyme arthritis. It has especially considered medical history including potential exposure to the infection, detailed characteristics of the symptoms, diagnostic challenges and results of the treatment. Only some patients had a history of erythema migrans and not all of them recalled tick-bite. The majority of the patients had affected large joints, especially knee joints, and polyarthritis was rarely observed. Symptoms were resolved completely or partially after antibiotic treatment in most patients. The diagnosis of Lyme arthritis in areas endemic for Lyme disease is still a diagnostic challenge in patients with other rheumatic diseases, including osteoarthritis.

RESUMEN

Lyme disease is a common tick-borne infection caused by Borrelia burgdorferi in the United States, where infection is most prevalent in the northeastern and mid-Atlantic states. Although classically associated with erythema migrans, Lyme disease caused by Borrelia species found in Europe may also present with other cutaneous findings. Here we report the case of a girl who was clinically diagnosed with Lyme disease based on her history of recent travel and the appearance of an areolar lymphocytoma; this was confirmed by testing. Testing for European Lyme disease does not follow the testing algorithm that the Centers for Disease Control and Prevention recommends and may be easily missed. Our case serves as an important reminder that common infections can have varying presentations depending on their region of acquisition and may require specialized testing for accurate diagnosis.

RESUMEN

Lyme borreliosis (LB) is the most prevalent tick-borne disease in Europe. Erythema migrans (EM), an early, localised skin rash, is its most common presentation. Dissemination of the bacteria can lead to more severe manifestations including skin, neurological, cardiac, musculoskeletal and ocular manifestations. Comparison of LB incidence rates in the European Union (EU)/European Economic Area (EEA) and Balkan countries are difficult in the absence of standardised surveillance and reporting procedures. We explored six surveillance scenarios for LB surveillance in the EU/EEA, based on the following key indicators: (i) erythema migrans, (ii) neuroborreliosis, (iii) all human LB manifestations, (iv) seroprevalence, (v) tick bites, and (vi) infected ticks and reservoir hosts. In our opinion, neuroborreliosis seems most feasible and useful as the standard key indicator, being one of the most frequent severe LB manifestations, with the possibility of a specific case definition. Additional surveillance with erythema migrans as key indicator would add value to the surveillance of neuroborreliosis and lead to a more complete picture of LB epidemiology in the EU/EEA. The other scenarios have less value as a basis for EU-level surveillance, but can be considered periodically and locally, as they could supply complementary insights.

RESUMEN

The spectrum of skin manifestations of Lyme borreliosis in children is not well characterized. We conducted a retrospective study to analyze the clinical characteristics, seroreactivity to Borrelia burgdorferi sensu lato, and outcome after treatment in 204 children with skin manifestations of Lyme borreliosis seen in 1996-2011. Solitary erythema migrans was the most common manifestation (44.6%), followed by erythema migrans with multiple lesions (27%), borrelial lymphocytoma (21.6%), and acrodermatitis chronica atrophicans (0.9%). A collision lesion of a primary borrelial lymphocytoma and a surrounding secondary erythema migrans was diagnosed in 5.9% of children. Rate of seroreactivity to B. burgdorferi s.l. was lower in solitary erythema migrans compared to other diagnosis groups. Amoxicillin or phenoxymethylpenicillin led to complete resolution of erythema migrans within a median of 6 (solitary) and 14 days (multiple lesions), respectively, and of borrelia lymphocytoma within a median of 56 days. In conclusion, erythema migrans with multiple lesions and borrelial lymphocytoma appear to be more frequent in children than in adults, whereas acrodermatitis chronica atrophicans is a rarity in childhood. The outcome after antibiotic therapy was excellent in children, and appears to be better than in adults.

RESUMEN

Lyme disease (LD) is a tick-borne, multisystemic infection caused by Borrelia burgdorferi. Although variable rates of seropositivity for B.burgdorferi have been reported between 2% to 44% in Turkey, its actual prevalence is not well-understood. The aim of this retrospective study was to evaluate the characteristics of 10 cases of LD presenting as erythema migrans (EM) between 2009 and 2013 from Istanbul which is one of the metropolitan cities of Turkey. Of the patients, five were male and five were female, ages between 9-51 years (mean age: 34.5 years). Five of the patients were admitted in June, three in October, one in November and two in December and all have the history of tick bite in last 1-2 weeks. There were no clinical symptoms for systemic infection among the patients with normal level routine laboratory test (whole blood count and biochemical tests) results. Five of the cases had EM lesions in the trunk, three in the upper extremities, and two in the lower extremities. Four patients presented with annular, three with solitary macular, and three with target-like EM lesions. In all cases, the biopsy specimens were positive for B.burgdorferi sensu lato DNA with polymerase chain reaction and all were also positive in terms of B.burgdorferi IgM antibodies with ELISA. Nine patients were treated with oral doxycycline, 100 mg twice daily and one child patient was treated with oral amoxicillin 500 mg twice daily for 21 days. EM lesions disappeared within 2-4 weeks in all patients. There was no clinical evidence for systemic involvement in any of the patients like neurologic, cardiac, and joint involvement at the follow-ups on the third, sixth and 12(th) months. To our best knowledge, 10 patients in this study are the largest EM series reported from Turkey. The increase in the number of LD cases may be associated with increased tick bite and increased awareness due to the emergence of concurrent Crimean-Congo hemorrhagic fever epidemic in Turkey. As a result, when enlarged erythematous lesions on the skin were observed, LH must also be considered in differential diagnosis, history of tick bite should be questioned and etiological diagnostic test should be performed.

RESUMEN

OBJECTIVE: Our aim was to identify the most informative clinical and laboratory predictors of chronicity of Ixodes tick-borne borreliosis in the acute phase of the disease based on the "optimal cut-off values" (COV) and the predicted probability of the outcomes. METHODS: A retrospective cohort controlled study was carried out. We used the technique of ROC-analysis to estimate the information content of the clinical and laboratory indicators in patients with Ixodes tick-borne borreliosis in the acute phase of the disease with erythemal (n =16), non-erythemal (n = 77) forms of Ixodes tick-borne borreliosis and co-infection with the tick-borne encephalitis (n = 68) for the prediction of the outcomes: recovery or chronization. RESULTS: A retrospective analysis of clinical and laboratory parameters recorded in the acute phase of the disease in 161 patients with chronic Ixodes tick-borne borreliosis. The calculations were performed for the informative clinical and laboratory prognostic predictors of the outcomes for the intervals above and below the COVvalues are defined probabilities of recovery or chronization of Ixodes tick-borne borreliosis. A general predictor of outcomes for all clinicalforms of the disease--the interleukin 8--was established: the probability of chronization after erythemal form is 100.0% at the level of its production over 107.89 pg/ml (AUC = 1.0), after non-erythemal form is 54.63 ± 0.23% at serum concentrations above 94.64 pg/ml (AUC = 0.770), after co-infection with the tick-borne encephalitis is 52.69 ± 0.27% at the level of interleukin 8 above 84.96 pg/ml (AUC = 0.780). CONCLUSION: The results of the study suggest the possibility of predicting the outcomes of infection in the acute phase, which allows to optimize the etiopathogenic therapy of the disease in a timely manner.

RESUMEN

During the past four decades the number of reported Lyme disease diagnoses in the Netherlands has increased to 27.000 a year, with a yearly incidence of Lyme disease between 111 (95% CI 106-115) to 131 (95% CI 126-136) per 100,000 person years. A large part of all Lyme disease diagnoses concern the skin; in the Netherlands, 77-89% erythema migrans, 2-3% borrelia lymfocytoom and 1-3% acrodermatitis chronica atrophicans. These skin manifestations have a variable clinical expression, reason why they can be difficult to diagnose. Early recognition and treatment is important to prevent the development of systemic manifestations.

RESUMEN

Lyme borreliosis is the most common vectorborne disease in the northern hemisphere. It usually begins with erythema migrans; early disseminated infection particularly causes multiple erythema migrans or neurologic disease, and late manifestations predominantly include arthritis in North America, and acrodermatitis chronica atrophicans (ACA) in Europe. Diagnosis of Lyme borreliosis is based on characteristic clinical signs and symptoms, complemented by serological confirmation of infection once an antibody response has been mounted. Manifestations usually respond to appropriate antibiotic regimens, but the disease can be followed by sequelae, such as immune arthritis or residual damage to affected tissues. A subset of individuals reports persistent symptoms, including fatigue, pain, arthralgia, and neurocognitive symptoms, which in some people are severe enough to fulfil the criteria for post-treatment Lyme disease syndrome. The reported prevalence of such persistent symptoms following antimicrobial treatment varies considerably, and its pathophysiology is unclear. Persistent active infection in humans has not been identified as a cause of this syndrome, and randomized treatment trials have invariably failed to show any benefit of prolonged antibiotic treatment. For prevention of Lyme borreliosis, post-exposure prophylaxis may be indicated in specific cases, and novel vaccine strategies are under development.

RESUMEN

BACKGROUND: It is heavily debated whether tick-borne infections cause chronic subjective health complaints. If the hypothesis of a major causal connection is true, one would expect to find more subjective health complaints in a population with high exposure to ticks than in a population with less exposure. In the current study we aimed to assess somatic symptoms and fatigue in a Norwegian population with high exposure to ticks, compare our findings to normative data, and assess predictors of somatic symptom load. MATERIAL AND METHODS: All individuals aged 18-69 years with residential address in Søgne municipality in southern Norway were in the period June 2015 to June 2016 invited to participate in the study. Somatic symptoms were assessed by the Patient Health Questionnaire-15 (PHQ-15) and fatigue by the Fatigue Severity Scale (FSS). A multivariable regression analysis was performed to assess predictors of somatic symptom load. RESULTS: Out of 7424 invited individuals, 2971 (40.0%) returned the questionnaire. 85.1% of 2950 responders reported exposure to tick-bite. PHQ-15 mean sum score was 5.3, and 16.5% reported moderate to severe somatic symptom load (i.e. ≥ 10). FSS mean score was 3.2, and 29.8% scored above the cut-off value for fatigue (i.e. ≥ 4.0). All gender and age groups in our study population had equal or lower mean sum score on PHQ-15 than reported in Swedish normative data, and lower mean score on FSS than reported in Norwegian normative data. In multivariable regression the following factors were associated with higher somatic symptom load (listed in order of descending beta coefficient): Anxiety and depression, number of other diseases, female gender, younger age, recruitment when visiting general practitioner's office, ≤ 6 years education after primary school, tick-bite earlier in life, erythema migrans earlier in life, less physical activity, and modern health worries. CONCLUSION: The study population reported high exposure to tick-bites, but less or equal level of somatic symptoms and less fatigue than found in normative data. There was a weak association between somatic symptom load and exposure to tick-bite and erythema migrans, possibly related to selection bias. Our findings do not support the hypothesis of a major causal connection between tick-borne infections and subjective health complaints.

RESUMEN

Erythema migrans (EM) rashes once considered pathognomonic of Lyme disease (LD) have been reported following bites of arthropods that do not transmit LD and in areas with no LD. Also, EM rashes have been reported in association with organisms other than members of Borrelia burgdorferi sensu lato complex. Arthropod saliva has chemicals that have effects on the host and pathogen transmission. Tick saliva has protein families similar to spiders and scorpions and even substances homologous to those found in snakes and other venomous animals. Ticks "invertebrate pharmacologists" have a sophisticated arsenal of chemicals that assist in blood feeding, pathogen transmission, and suppressing host defenses. No organisms have been isolated from many EM rashes. We propose that tick salivary toxins may play a role in the causation of rashes and laboratory abnormalities in tick-borne diseases. The role of tick salivary toxins needs further exploration. Cases of Lyme-like EM rashes referred to as STARI (Southern Tick-Associated Rash Illness) following bites of the lone star tick, Amblyomma americanum, in the United States have been reported predominantly in Southeastern Missouri and a few in South Carolina, North Carolina, Georgia, and one case each in Mississippi and Long Island, New York. Although there is one report of Borrelia lonestari in a patient with a rash, biopsies of 31 cases of STARI, with cultures and PCR, failed to show a relationship. Distribution of A. americanum, whose bites are associated with STARI, now extends along the East Coast of the United States, including New Jersey, up to the Canadian border. As far as we are aware, there have been no prior reports of Lyme-like rashes in New Jersey. In this study, we present case examples of 2 Lyme-like rashes, variations of EM rashes, and a brief review of studies that suggest a role of tick salivary toxins in tick-borne diseases.

RESUMEN

Erythema migrans (EM) must be distinguished from other entities including streptococcal and staphylococcal cellulitis, hypersensitivity reactions to arthropod bites, plant dermatitis, tinea, and granuloma annulare. Although EM lesions may be pruritic or painful, these complaints are generally mild. Central clearing may be absent in > 50% of patients. Multiple lesions, formerly present in 50% of U.S. patients, now occur in approximately 20%. EM develops days to 1 month after a tick bite (median 7-10 days), and lesion diameter increases with duration. Most patients have associated complaints, with fatigue (54%), myalgia (44%), arthralgia (44%), headache (42%), and fever and/or chills (39%) being the most common. Respiratory and gastrointestinal complaints are infrequent. Symptoms may begin prior to the onset of, concomitant with, or after resolution of the rash. The incidence of viral-like illness due to Lyme disease without EM is unknown. Antibodies to Borrelia burgdorferi are absent in up to 50% of patients at presentation, with initial seropositivity most likely in those with EM of longer duration. The vast majority of patients will become seropositive within the first month of illness, even with treatment. Although there is evidence that B. burgdorferi can spread to the blood and central nervous system soon after onset of infection, oral therapy is highly effective in preventing objective extracutaneous complications of Lyme disease. The most appropriate choice, route of administration, and duration of therapy require further study. Because of variations in the etiologic agent between North America and Europe, comparisons of disease manifestations, treatment, and prognosis of Lyme disease must be made cautiously.

RESUMEN

Borrelia burgdorferi sensu lato, the aetiological agent of Lyme disease, has been subdivided into three species: B. burgdorferi sensu stricto, B. garinii and B. afzelii. We and other authors have hypothesized an association between the three species of B. burgdorferi sensu lato and some of the different clinical manifestations of Lyme disease. In order to demonstrate this hypothesis, we analysed twenty-nine isolates cultured from patients with different symptoms. The method used was multilocus enzyme electrophoresis: twelve genetic loci were characterized on the basis of the electrophoretic mobility of their products, and twenty-eight distinctive allele profiles (electrophoretic types) were distinguished, among which mean genetic diversity per locus was 0.649. Cluster analysis of a matrix of genetic distances between paired electrophoretic types revealed three primary divisions separated at genetic distances greater than 0.7 and corresponding to the three species of B. burgdorferi sensu lato. Ten strains obtained from skin of patients with erythema chronicum migrans (the primary stage of the disease) were assigned to the three different species. All the six strains isolated from patients with acrodermatitis chronica atrophicans were of the species B. afzelii, which was not found to be associated with another chronic manifestation of Lyme disease. Arthritis was caused prevalently by B. burgdorferi sensu stricto, and neuroborreliosis by B. burgdorferi sensu stricto and B. garinii. In conclusion, our results confirm the association between some of the different chronic manifestations of the disease and the species of B. burgdorferi sensu lato.

RESUMEN

In 1982 and 1983 practicing pediatricians in a Lyme disease-endemic county, reported 90 cases of Lyme disease among children 19 years of age and younger (median age, 9 years). Three-fourths of the children had initial symptom onset in the summer months, with peak incidence in July. Infection occurred twice as often in boys than in girls, and tick bites were recalled by less than half (49%) of the children or parents. Erythema chronicum migrans was present in two-thirds (67%) of the cases with median onset 7 days after a definite tick bite. Arthritis or arthralgia occurred in 59% and neurologic symptoms, especially seventh nerve palsy, occurred in 14%. Asymmetric involvement of a few large joints, especially the knee, was most commonly reported for those with joint involvement. antibiotics were prescribed for 79% of the children, three-fourths of whom were treated with oral penicillin. Initial diagnosis of Lyme disease is usually made on clinical grounds alone because serologic tests are often negative. Serologic tests for antibody to Borrelia burgdorferi were more often positive in cases with neurological or joint involvement, in addition to erythema chronicums migrans (80%), than in cases presenting with erythema chronicums migrans only.

RESUMEN

Involvement of adult Ixodes persulcatus ticks in the transmission of Lyme disease in Hailin County, Heilongjiang Province, China, is reported. In 1986 from April through August adult I. persulcatus was the dominant tick in this endemic area with an infection rate of 43% for the Lyme disease spirochaete, Borrelia burgdorferi. The incidence of Lyme disease cases presenting the symptom of erythema chronicum migrans (ECM) within this area was correlated with the seasonal abundance of adult I. persulcatus and the number of people bitten by ticks. The frequency of ECM formation in all age groups varied and was associated with the frequency of tick bites. In addition, a strain of B. burgdorferi was isolated from a pool of six female I. persulcatus collected from this area. We demonstrate that the seasonal abundance of adult I. persulcatus and its frequent attachment to humans result in the spring and summer transmission of Lyme disease in this endemic area. The role of immature I. persulcatus in Lyme disease transmission is apparently minimal.
