OBJECTIVES:
We sought to identify predictive factors for Lyme carditis
in children and to characterize the clinical course of these
patients. METHODS: We reviewed all cases of early
disseminated Lyme disease presenting to our institution from
January 1994 through July 2008, and summarized the
presentation and course of those patients with carditis. A
case-control study was used to identify predictive factors
for carditis. Controls were patients with early disseminated
Lyme disease without carditis. RESULTS: Of 207 children with
early disseminated Lyme disease, 33 (16%) had carditis, 14
(42%) of whom had advanced heart block, including 9 (27%)
with complete heart block. The median time to recovery of
sinus rhythm in these 14 patients was 3 days (range: 1-7
days), and none required a permanent pacemaker. Four (12%)
of 33 patients with carditis had depressed ventricular
systolic function, 3 (9%) of whom required mechanical
ventilation, temporary pacing, and inotropic support.
Complete resolution of rhythm disturbances and myocardial
dysfunction occurred in 24 (89%) of 27 patients for whom
follow-up data were available. Most patients with carditis
also had other systemic Lyme involvement. By using
multivariate logistic regression analysis, we found that
children >10 years of age, those with arthralgias, and
those with cardiopulmonary symptoms were more likely to have
carditis. CONCLUSIONS: The spectrum of presentation for
children with Lyme carditis is broad, ranging from
asymptomatic, first-degree heart block to fulminant
myocarditis. Variable degrees of heart block are the most
common manifestation and occasionally require temporary
pacing. Transient myocardial dysfunction, although less
common, can be life-threatening. Advanced heart block
resolves within 1 week in most cases. In children with early
disseminated Lyme disease, older age, arthralgias, and
cardiopulmonary symptoms independently predict the presence
of carditis.

Lyme
Carditis:
cardiac abnormalities of Lyme disease.
Ann
Intern Med. 1980 Jul;93(1):8-16.
Steere AC, Batsford WP, Weinberg M, Alexander J, Berger
HJ, Wolfson S, Malawista SE.
We studied
20 patients, mostly young adult men, with cardiac
involvement of Lyme disease. The commonest abnormality (18
patients) was fluctuating degrees of atrioventricular block;
eight of them developed complete heart block. Thirteen
patients had evidence of more diffuse cardiac involvement:
electrocardiographic changes compatible with acute
myopericarditis (11 patients), radionuclide evidence of mild
left ventricular dysfunction (five of 12 patients tested),
or frank cardiomegaly (one patient). Heart involvement was
usually preceded by erythema chronicum migrans and sometimes
accompanied by meningoencephalitis, facial palsy, arthritis,
elevated serum IgM levels, or cryoglobulins containing IgM.
The duration of cardiac involvement was usually brief (3
days to 6 weeks). The clinical picture in these patients has
similarities to acute rheumatic fever; but in Lyme disease,
complete heart block may be commoner, myopericardial
involvement tends to be milder, and valves seem not to be
affected.

Complete heart block due to
Lyme Carditis.

Lyme carditis is becoming a more frequent complication of Lyme disease, primarily due to the increasing incidence of this disease in the United States. Cardiovascular manifestations of Lyme disease often occur within 21 days of exposure and include fluctuating degrees of atrioventricular (AV) block, acute myopericarditis or mild left ventricular dysfunction and rarely cardiomegaly or fatal pericarditis. AV block can vary from first-, second-, third-degree heart block, to junctional rhythm and asystolic pauses. Patients with suspected or known Lyme disease presenting with cardiac symptoms, or patients in an endemic area presenting with cardiac symptoms with no other cardiac risk factors should have a screening electrocardiogram along with Lyme titers. We present a case of third-degree AV block due to Lyme carditis, illustrating one of the cardiac complications of Lyme disease. This disease is usually self-limiting when treated appropriately with antibiotics, and does not require permanent cardiac pacing.

We describe a case of progressive arrhythmia and heart failure combined with neurological symptoms that was resistant to conventional cardiological treatment. The outcome of a serological analysis was Borrelia IgG on a level consistent with chronic Lyme Disease. Antibiotic treatment with doxycycline resulted in complete remission of all cardiological symptoms. This case demonstrated Lyme Disease to be a potential factor in the pathogenesis of myocarditis as suggested by international publications.

Molecular diagnosis of culture negative infective
endocarditis: clinical validation in a group of surgically treated patients.

OBJECTIVE: To assess the clinical validity of polymerase chain reaction (PCR) based molecular methods in the microbiological diagnosis of culture negative infective endocarditis in a group of surgically treated patients. DESIGN: Retrospective case-control study. SETTING: Reference cardiovascular surgical centre. PATIENTS AND SAMPLES: 15 culture negative patients with infective endocarditis classified according to Duke criteria, with 17 heart valve samples; 13 age and sex matched control patients without infective endocarditis, with 13 valve samples.
INTERVENTIONS: Medical records were reviewed and clinical, demographic, and microbiological data collected, including results of molecular detection of bacteria and fungi from valve samples. The clinical validity of molecular diagnosis was assessed, along with the sensitivity and speed of the systems. RESULTS: In the study group, 14 patients were PCR positive (93%). Organisms detected were streptococci (3), staphylococci (2), enterobacter (1), Tropheryma whippelii (1), Borrelia burgdorferi (1), Candida albicans (1), and Aspergillus species (2). Three cases were positive on universal bacterial detection but the pathogen could not be identified because of contaminating background. One case was negative. All but two positive cases showed clinical correlations. These two cases had no symptoms of infective endocarditis but there was agreement with the surgical findings. All control cases were PCR negative. Results were available within eight hours, and if sequencing was necessary, within 48 hours.
CONCLUSIONS: PCR based molecular detection of pathogens in valve samples from surgically treated culture negative infective endocarditis patients is fast, sensitive, and reliable. The technology, combined with thorough validation and clinical interpretation, may be a promising tool for routine testing of infective endocarditis.

BACKGROUND: Although the frequency of Lyme carditis is not high, it is one of the most challenging conditions in terms of diagnosis. No long-term studies that would help expand our body of knowledge concerning the circumstances of its development and the natural course of this form of Lyme borreliosis (LB), the most widespread anthropozoonosis in Central Europe, have been reported to date. AIM: The authors sought to describe and assess the consequences of a less common form of Lyme carditis (LC). An assessment of the following aspects was made: a) the forms, natural history and sequelae of the less common clinical appearances of LC, b) the role of antibiotic therapy with reference to the late manifestations of LB.
METHODS: Three patients were selected from a group of 60 consecutive patients with demonstrated LC during a follow-up period from 1987 to 2000. Patient no. 1 was being followed for myocarditis with frequent ventricular extrasystoles, patient no. 2 for pericarditis, and patient no. 3 for dilated cardiomyopathy as a late manifestation of LB. In addition to routine examination at entry, the patients were subjected to a standard 12-lead ECG, continuous 24-hour Holter ECG monitoring, exercise testing (bicycle ergometry), investigations of antibodies using ELISA and Western blot, investigation of thyroid (T3, T4, TSH tests) and mineral levels.
RESULTS: The study showed no significant correlation between the clinical course and levels of specific antibodies. It confirmed the concept that inadequate or no therapy with antibiotics in the initial stage of the disease has a significant effect on the development of late sequelae. CONCLUSION: Based on the long-term treatment of three patients with less common, yet clinically urgent findings, the authors conclude that even a relatively serious clinical course is associated with no major limitations for affected individuals after an interval of several years.

Update on Lyme Carditis.

Lyme carditis is an uncommon manifestation of infection with Borrelia bugdorferi. It is easily treated with standard antibiotic regimens and prognosis is excellent, especially if treatment is prompt. For symptomatic or higher degrees of block, patients may require hospitalization for monitoring and occasionally temporary external pacing. Intravenous antibiotics are warranted for such patients. For less severe conduction disturbances, oral therapy suffices.

Cardiac manifestations of Lyme disease.

Lyme disease is a vector-borne illness that can affect numerous organ systems during the early disseminated phase, including the heart. The clinical course of Lyme carditis is usually benign with most patients recovering completely. In rare instances, death from Lyme carditis has been reported. The cardinal manifestation of Lyme carditis is conduction system disease, which generally is self-limited. Heart block occurs usually at the level of the atrioventricular node but often is unresponsive to atropine sulfate. Temporary pacing may be necessary in more than 30% of patients, but permanent heart block rarely develops. Myocardial and pericardial involvement can occur but generally is mild and self-limited. Diagnosis is made by associating the clinical and historical features of borreliosis, such as previous tick bite, EM, or neurologic involvement, with electrocardiographic abnormalities and symptoms such as chest pain, palpitations, syncope, and dyspnea.
Serologic studies and endomyocardial biopsy can only support the clinical diagnosis in the correct setting, and MR imaging, echocardiography, and gallium scanning have utility in selected circumstances. No treatment has been shown clearly to attenuate or prevent the development of Lyme carditis, but mild carditis generally is treated with oral antibiotics and severe carditis with intravenous antibiotics in an effort to eradicate the infection and prevent late complications of Lyme disease. There is conflicting evidence regarding the role that B. burgdorferi plays in the development and progression of chronic congestive heart failure. Because of the significant false-positive ELISA rate in this population and the unclear benefit of antibiotic therapy, confirmatory Western blot analysis is recommended. Routine therapy and screening of patients with idiopathic dilated cardiomyopathy is of limited utility and should be reserved for patients with clear history of antecedent Lyme disease or tick bite.

Abstract: Characteristically, in infections
that are caused by the zoonotic pathogen Bartonella naturally
infected reservoir hosts are asymptomatic, where infected incidental,
non-natural, hosts develop symptomatic disease. Cat-scratch disease (CSD)
is a well known example. Bartonella infections in humans may be
self-limiting or fulminant and affect different organ systems. The
objectives of the present thesis were to (1) identify and characterise Bartonella
infection cases in Sweden, (2) to investigate certain human
populations regarding Bartonella infections, and (3) compare
natural populations of different Bartonella species. Cases with
typical and atypical CSD were recognised by using a combination of PCR
and serology. Gene sequence comparisons of different genes in B.
henselae isolates from the United States and Europe showed that
ftsZ gene variation is a useful tool for Bartonella
genotyping. Myocarditis was a common finding among Swedish elite
orienteers succumbing to sudden unexpected cardiac death (SUCD). The
natural cycle of Bartonella spp., the life style of orienteers,
elevated antibody titres to Bartonella antigens, Bartonella
DNA amplified from myocardium
and the lack of another feasible explanation make Bartonella a
plausible aetiological factor. The first reported case of Bartonella
endocarditis (B. quintana) was identified in an
immunocompromised patient who underwent heart valve replacement. The
patient had been body louse-infested during his childhood. It is
hypothesised that a chronic B. quintana infection was activated
by the immunosuppression. There was no evidence of an ongoing trench
fever (TF) epidemic in a Swedish homeless population, although an
increased risk for exposure to Bartonella antigens was
demonstrated. The lack of louse infestation might explain the absence of
B. quintana bacteremia and low B. quintana antibody titres.
Comparisons of genetic loci and the whole genomes of environmental B.
grahamii isolates from the Uppsala region, Sweden displayed variants
that were not related to specific host species but to geographic
locality. Natural boundaries seemed to restrict gene flow.
