Some patients with a history of Borrelia burgdorferi infection develop a chronic symptomatology characterized by cognitive deficits, fatigue, and pain, despite antibiotic treatment. The pathogenic mechanism that underlines this condition, referred to as post-treatment Lyme disease syndrome (PTLDS), is currently unknown. A debate exists about whether PTLDS is due to persistent infection or to post-infectious damages in the immune system and the nervous system. We present the case of a patient with evidence of exposure to Borrelia burgdorferi sl and a long history of debilitating fatigue, cognitive abnormalities and autonomic nervous system issues...

Non-human primates currently serve as the best experimental model for Lyme disease due to their close genetic homology with humans and demonstration of all three phases of disease following infection with Borreliella (Borrelia) burgdorferi (Bb). We investigated the pathology associated with late disseminated Lyme disease (12 to 13 months following tick inoculation) in doxycycline-treated (28 days; 5mg/kg, oral, 2x/day) and untreated rhesus macaques (Rm). Minimal to moderate lymphoplasmacytic inflammation, with a predilection for perivascular spaces and collagenous tissues, was observed in multiple tissues including the cerebral leptomeninges, brainstem, peripheral nerves from both fore and hind limbs, stifle synovium and perisynovial adipose tissue, urinary bladder, skeletal muscle, myocardium, and visceral pericardium...

Complement is an important part of innate immunity. The alternative pathway of complement is activated when the main opsonin, C3b coats non-protected surfaces leading to opsonisation, phagocytosis and cell lysis. The alternative pathway is tightly controlled to prevent autoactivation towards host cells. The main regulator of the alternative pathway is factor H (FH), a soluble glycoprotein that terminates complement activation in multiple ways. FH recognizes host cell surfaces via domains 19-20 (FH19-20). All microbes including Borrelia burgdorferi, the causative agent of Lyme borreliosis, must evade complement activation to allow the infectious agent to survive in its host...

Ticks are tiny crawling bugs in the spider family that feed by sucking blood from animals. They are second only to mosquitoes as vectors of human disease, both infectious and toxic. Infected ticks spread over a hundred diseases, some of which are fatal if undetected. They spread the spirochete (which multiplies in the insect's gut) with a subsequent bite to the next host. We describe the only reported cases of peri ocular tick bite from India that presented to us within a span of 3 days and its management. Due suspicion and magnification of the lesions revealed the ticks which otherwise masqueraded as small skin tags/moles on gross examination...

Although the majority of patients with acute Lyme disease can be cured with the standard 2-4 week antibiotic treatment, about 10-20% of patients continue suffering from chronic symptoms described as posttreatment Lyme disease syndrome. While the cause for this is debated, one possibility is that persister bacteria are not killed by the current Lyme antibiotics and remain active in the system. It has been reported that essential oils have antimicrobial activities and some have been used by patients with persisting Lyme disease symptoms...

This chapter reviews the diseases of the peripheral nerves from a neuropathologic point of view, with a special focus on specific morphologic changes, and includes a summary of the histopathologic methods available for their diagnosis. As the rate of obesity and the prevalence of type 2 diabetes increase, diabetic neuropathy is the most common cause of peripheral neuropathy. Many systemic disorders with metabolic origin, like amyloidosis, hepatic failure, vitamin deficiencies, uremia, lipid metabolism disorders, and others, can also cause axonal or myelin alterations in the peripheral nervous system...

Borrelia burgdorferi (Bb) is the causative agent of Lyme disease in the United States, a disease that can result in carditis, and chronic and debilitating arthritis and/or neurologic symptoms if left untreated. Bb survives in the midgut of the Ixodes scapularis tick, or within tissues of immunocompetent hosts. In the early stages of infection, the bacteria are present in the bloodstream where they must resist clearance by the innate immune system of the host. We have found a novel role for outer surface protein C (OspC) from B...

Post-treatment Lyme disease syndrome (PTLDS) is a pain disorder for which there remains no gold standard treatment option. Here, we report a case of PTLDS in a female patient whose pain was refractory to treatment options such as radiofrequency ablation, vitamin infusion therapy, opioid analgesics, and other pharmacotherapies. The patient commenced an experimental intravenous ketamine infusion therapy at the Florida Spine Institute (Clearwater, FL, USA) and achieved relief from her chronic pain, an improved quality of life, reduced depression and suicidal ideation, and reduced opioid consumption...

Lyme disease is a zoonosis caused by infection with bacteria belonging to the Borrelia burgdorferi species after the bite of an infected tick. Even though an infection by this bacterium can be effectively treated with antibiotics, when the infection stays unnoticed B. burgdorferi can persist and chronic post-treatment Lyme disease syndrome is able to develop. Although a cellular and humoral response is observed after an infection with the Borrelia bacteria, these pathogens are still capable to stay alive. Several immune evasive mechanisms have been revealed and explained and much work has been put into the understanding of the contribution of the innate and adaptive immune response...

The population dynamics of pathogens within hosts result from interactions between host immune responses and mechanisms of the pathogen to evade or resist immune responses. Vertebrate hosts have evolved adaptive immune responses to eliminate the infection, while many pathogens evade immune clearance through altering surface antigens. Such interactions can result in a characteristic pattern of pathogen population dynamics within hosts consisting of population growth after infection, rapid population decline following specific immune responses, followed by persistence at low densities during a chronic infection stage...

The histopathological synovitis score evaluates the immunological and inflammatory changes of synovitis in a graduated manner generally customary for diagnostic histopathological scores. The score results from semiquantitative evaluation of the width of the synovial surface cell layer, the cell density of the stroma and the density of the inflammatory infiltration into 4 semiquantitative levels (normal 0, mild 1, moderate 2, severe 3). The addition of these values results in a final score of 0-9 out of 9. On the basis of this summation the condition is divided into low-grade synovitis and high-grade synovitis: A synovitis score of 1 to≤4 is called low-grade synovitis (arthrosis-associated/OA synovitis, posttraumatic synovitis, meniscopathy-associated synovitis and synovitis with haemochromatosis)...

PURPOSE OF REVIEW: Lyme disease is a tick-borne zoonosis transmitted through a bite of a tick carrying a spirochete belonging to Borrelia species. In the last 20 years, the reported incidence of Lyme disease is increased by three times in Europe. Clinically, the illness develops through a primary stage with a typical skin rash (erythema marginatum), then a secondary stage with possible neurologic or cardiac involvement. The last stage (chronic Lyme disease) is mainly represented by arthritis or late neurological complications but nowadays is rarely seen due to precocious antibiotic use...

PURPOSE: The aim of this paper is to investigate the association between suicide and Lyme and associated diseases (LAD). No journal article has previously performed a comprehensive assessment of this subject. INTRODUCTION: Multiple case reports and other references demonstrate a causal association between suicidal risk and LAD. Suicide risk is greater in outdoor workers and veterans, both with greater LAD exposure. Multiple studies demonstrate many infections and the associated proinflammatory cytokines, inflammatory-mediated metabolic changes, and quinolinic acid and glutamate changes alter neural circuits which increase suicidality...

Lyme disease is a zoonosis caused by infection with Borrelia burgdorferi (Bb). A great amount of research has attempted to elucidate the mechanisms by which Bb causes inflammation and chronic symptomatology in some patients. Patients often seek unconventional treatments that lack scientific evidence, as medical care is unable to effectively explain and treat their illness. Bb-DNA can persist for long periods of time in some individuals, even after antibiotic therapy. Herein, scientific rationale is presented for a new therapeutic approach against remaining bacterial DNA, and/or increasing the ability of human macrophages to remove extracellular Bb DNA...

The term "chronic Lyme disease" is used by some health care providers as a diagnosis for various constitutional, musculoskeletal, and neuropsychiatric symptoms (1,2). Patients with a diagnosis of chronic Lyme disease have been provided a wide range of medications as treatment, including long courses of intravenous (IV) antibiotics (3,4). Studies have not shown that such treatments lead to substantial long-term improvement for patients, and they can be harmful (1,5). This report describes cases of septic shock, osteomyelitis, Clostridium difficile colitis, and paraspinal abscess resulting from treatments for chronic Lyme disease...
