Chronic Lyme disease

Chronic Lyme disease is caused by the bacterium Borrelia burgdorferi and transmitted through the bite of a black legged ticks.

Symptoms
The signs and symptoms of Lyme disease vary and usually appear in stages.

Early Signs and Symptoms
 * Bull's eye rash (Not always present.)
 * Flu-like symptoms

Later Signs and Symptoms
 * Erythema migrans
 * Neurological problems

Less Common Signs and Symptoms
 * Heart problems, such as irregular heartbeat.
 * Eye inflammation
 * Liver inflammation (hepatitis).
 * Severe fatigue

United States

 * Two-step Laboratory Testing Process CDC: EIA/IFA and Western Blot
 * Types of Lyme Disease Tests LymeDiseaseGuide.org
 * Laboratory tests that are not recommended CDC

UK

 * BBC1 Lyme Disease Discussion - Some patients have waited up to 30 years for a correct diagnosis. National Health Service (NHS) services have only correctly identified the disease in a quarter of the patients. The blood tests are unreliable and often come back negative. The development of an accurate blood test is in need of research funding.

False positives
Several herpesviruses including varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and HSV-2 may cause false positives on Lyme Disease tests.

Treatment & Management

 * Approach Considerations
 * Treatment of Early Lyme disease
 * Post-Treatment Lyme Disease Syndrome (Chronic lyme disease)

Herpesviruses
Lyme may cause reactivation of latent herpesviruses. At the same time, several herpesviruses including varicella zoster virus, cytomegalovirus, Epstein-Barr virus, and HSV-2 may cause false positives on Lyme Disease tests.

Pathobiome Paradigm
Some future research will focus on a spectrum of pathogens instead of a "one pathogen-one disease" vision.

Lyme Disease vs Chronic Fatigue Syndrome

 * 2016, Post Lyme Disease and Chronic Fatigue Syndrome (ME/CFS) – Are They The Same?


 * 2011, Lyme Disease and Chronic Fatigue Syndrome are different diseases. Research is published on cerebrospinal fluid, and distinct differences were found.


 * 2009, "The Department of Health remains concerned about the growing number of patients, particularly those suffering from chronic conditions such as myalgic encephalopathy (ME) or chronic fatigue syndrome, who receive a false diagnosis of Lyme disease from private laboratories offering unvalidated tests that lack the sensitivity and specificity to detect B. burgdorferi. A report of the Department’s investigation into the use of such tests in the diagnosis of Lyme disease is available at Report on Lyme Disease: Unorthodox and Unvalidated Laboratory Tests in the Diagnosis of Lyme Borreliosis and in Relation to Medically Unexplained Symptoms. Misinformation about Lyme disease is readily available to patients via the internet and can lead them to seek inappropriate diagnosis and treatment."


 * There are many historical outbreaks of Myalgic Encephalomyelitis and Chronic Fatigue Syndrome that do not correlate with a tick-borne pathogen.
