For early Lyme disease, a short course of oral antibiotics, such as doxycycline or amoxicillin, cures the majority of cases. In more complicated cases, Lyme disease can usually be successfully treated with three to four weeks of antibiotic therapy. After being treated for Lyme disease, a minority of patients may still report non-specific symptoms, including persistent pain, joint and muscle aches, fatigue, impaired cognitive function, or unexplained numbness. These patients often show no evidence of active infection and may be diagnosed with post-treatment Lyme disease syndrome (PTLDS). Multiple clinical trials, funded by NIH and others, have shown no benefit to additional IV antibiotic treatment in patients with Lyme disease, although the interpretation of those results have been challenged by some. NIAID has funded three placebo-controlled clinical trials to learn more about the efficacy of prolonged antibiotic therapy for treating PLDS. The published results were subjected to rigorous statistical, editorial, and scientific peer review. If you’re bitten by an infected tick, this microbe enters your bloodstream and can make you sick with an illness called Lyme disease. It’s the most common illness carried by ticks in the United States. That includes your nervous system and brain, heart and joints. Early symptoms such as headaches and body aches are often mistaken for other health problems. How you’re treated will depend on how much bacteria has spread through your body by the time you’re diagnosed. Which drug you’re prescribed will depend on your age. Your doctor will also take into account if you’re pregnant or nursing. You’ll need to take this medicine for 10 to 21 days. Most people who start treatment in this stage improve quickly. If not, your doctor may need to prescribe another course of antibiotics. bacteria has spread to your central nervous system, you can still be treated with antibiotics.
13, 2017—Bay Area Lyme Foundation, a leading sponsor of Lyme disease research in the US, today announced results of two papers published in the peer-reviewed journals PLOS ONE and American Journal of Pathology, that seem to support claims of lingering symptoms reported by many patients who have already received antibiotic treatment for the disease. The study also measured the antibody immune response to the bacteria both pre- and post- treatment, as this is how current diagnostics typically evaluate Lyme disease in humans. The data show that living bacteria, which have had time to adapt to their host, have the ability to escape immune recognition, tolerate the antibiotic doxycycline and invade vital organs such as the brain and heart, said lead author Monica Embers, Ph D, assistant professor of microbiology and immunology at Tulane University School of Medicine. In this study, we were able to observe the existence of microscopic disease and low numbers of bacteria, which would be difficult to see in humans but could possibly be the cause of the variable and nonspecific symptoms that are characteristic of post-treatment Lyme disease syndrome. Although current antibiotic regimens may cure most patients who are treated early, if the infection is allowed to progress, the 28-day treatment may be insufficient, based on these findings, Embers said. The findings also demonstrated: This species has been shown to demonstrate a progression of Lyme disease most similar to humans, particularly related to erythema migrans, carditis, arthritis, and neuropathy of the peripheral and central nervous systems. Clearly, some medical practices governing diagnosis and treatment of Lyme disease should be reconsidered in light of this study. Antibiotic selection, route of administration, and duration of therapy for Lyme disease are guided by the patient’s clinical manifestations and stage of disease, as well as the presence of any concomitant medical conditions or allergies. Prompt treatment increases the likelihood of therapeutic success. With prompt and appropriate antibiotic treatment, most patients with early-stage Lyme disease recover rapidly and completely. Clinical presentation and therapy for the stages of Lyme disease (Open Table in a new window) In most patients with carditis, prompt institution of appropriate antibiotics is the only treatment needed. Of great importance, doxycycline is contraindicated in patients younger than 8 years and in pregnant women. However, occasional patients with Lyme disease–related atrioventricular (AV) block may require hospitalization for temporary cardiac pacing. The indications for cardiac pacing are the same as for any other patient with varying degrees of heart block. Symptoms of arthritis may persist for a few weeks beyond adequate therapy. Repeat treatment usually is not necessary unless symptoms worsen or persist beyond 2 months. Persistent arthritis after clearance of the infection is most likely related to autoimmunity and is more prevalent among individuals with HLA-DR2, HLA-DR3, or HLA-DR4 allotypes.
See Lyme Disease and 4 Emerging Tick-Borne Illnesses, a Critical Images slideshow, to help identify and treat several tick-borne conditions. Signs and symptoms of Lyme disease vary by disease stage. Physical findings in patients with early disease are as follows: In patients with late disease, the typical physical finding is arthritis. Arthritis is located mostly in large joints, especially the knee. Warmth, swelling from effusion, and limited range of motion help distinguish arthritis from simple arthralgia. In endemic areas, patients with probable erythema migrans and a recent source of tick exposure should be started on treatment without blood tests. For serologic testing, the CDC recommends a two-tier testing procedure, as follows Western blot testing is performed only if step 1 test results are positive or equivocal. Early records of conditions possibly associated with Lyme disease date back to the 1880s and on Long Island, for many years there was talk of "Montauk Knee" and "Long Island Malaria." Lyme disease is named after the one of the fastest growing vector borne diseases. Both humans and animals can be infected with Lyme disease through the bite of an infected tick. In the United States Lyme infection is usually transmitted by, though not limited to, three species of tick: The lone star tick (amblyomma americanum), was previously located predominantly in the south, but recently, the lone star tick is on the move and is said to be out-competing the other ticks and is now found in many areas of the Northeast. When Lyme disease goes undetected, undiagnosed and untreated for months or years following infection; the bacteria can spread to the nervous system, the heart and other organs, tendons and joints. This late-stage infection can result in a wide variety of physical, emotional, and mental or cognitive symptoms. The late-stage list of symptoms is long and can include arthritis, heart abnormalities, Bell's palsy (paralysis of one or both sides of the face) and severe cognitive or mental dysfunction including memory loss, confusion, psychiatric problems, etc. Misdiagnosed: Lyme disease is often referred to as the Great Pretender because the symptoms of Lyme disease can so closely mimic the symptoms of other diseases.

Borrelia mayonii, a bacterial species that causes Lyme disease in the upper Midwest, causes similar symptoms in its early stages, including fever, headache, neck pain, and rash, and arthritis pain.
