How Do I Know Whether I Have Received A Sufficiently Long Course Of Antibiotic Therapy

Antibody tests explained – IgG IgM

Taken together, these study results suggest that repeated antibiotic therapy may be beneficial for a subgroup of patients. However all of these studies also reported troubling adverse effects associated with the IV antibiotic therapy. Given these potentially dangerous risks, it is clear that other safer and more durable treatments are needed for patients with persistent symptoms.

Can Lyme Disease Be Sexually Transmitted

First of all, if you have been treated for Lyme disease, even if your Western blot is positive, it is very unlikely that there are any spirochetes still circulating in your bodily fluids. Second, there is no good documentation that Lyme disease can be contracted by sexual contact. Given the number of cases of Lyme disease that have been diagnosed over the last 20 years and the fact that there are have been instances where people with active infection are having sexual intercourse but have not yet been treated, one would expect there to be many well documented cases of suspect partner to partner transmission this is not the case. Therefore, for all these reasons, it is highly unlikely that a person could acquire Lyme disease through unprotected intercourse or other sexual contact.

Other Types Of Lyme Disease Tests

Though indirect tests are the most common, the following are also available:

  • Molecular tests: Molecular tests include the Polymerase Chain Reaction and the Fluorescent In Situ Hybridization . Like the most common tests for COVID-19, traditional and real-time PCR tests detect active infections in patient samples using Lyme DNA. The FISH test, on the other hand, detects bacteria, fungi, and intraerythrocytic parasites in red blood cells.
  • Antigen tests: These detect proteins in blood, urine, or joint fluid.
  • Culture tests: These work by attempting to grow Lyme spirochetes in a special medium using patient samples of blood or other fluids. This type of test can be highly accurate but it is a relatively new technology, so it is not yet widely available in the U.S.

The Role Of Lyme Disease Tests

The purpose of the most common type of Lyme disease testing is to determine whether you have developed antibodies as a result of past exposure to the Borrelia bacteria that cause Lyme disease. Antibodies are proteins created by the immune system that target specific threats like bacteria and viruses.

Blood testing alone cannot determine whether you have Lyme disease. Instead, testing can provide helpful information that your doctor can consider along with other factors, such as any symptoms youve had and whether youve been exposed to ticks that can carry Borrelia, to determine if a diagnosis of Lyme disease is appropriate.

Beyond blood testing, it is possible to analyze fluid from the central nervous system for signs of the Borrelia bacteria.

Cdc Supports The Development Of New Tests

PPT

New tests may be developed as alternatives to one or both steps of the two-step process. Before CDC will recommend new tests, they must be cleared by the Food and Drug Administration .

When Is The Lyme Disease Blood Test Ordered

When someone has the signs and symptoms of Lyme disease or they live in a region that has deer ticks or black-legged ticks, then this blood test will be ordered. It will also be ordered when these symptoms occur without improvement over the course of 7-14 days by most medical providers.

  • A bulls-eye rash that grows from the bite site.
  • Fevers, chills, and a persistent headache that does not go away.
  • Unusual and persistent fatigue that does not immediately improve.

The IgM and IgG tests are generally ordered first when Lyme disease is suspected. This is because people who have never been exposed to the bacteria that causes the disease will not have any antibodies present. If these tests are positive and followed up by a positive Western Blot test, then the chances are very good that Lyme disease is present. This is especially true if antibody levels continue to rise over time.

How Long Do Lyme Igm Antibodies Last

As mentioned above, IgM antibodies are not long-lasting. They are typically only produced at the beginning of an infection and slowly decrease in the few weeks that follow. They act as short-term protection, jump-starting the bodys defences against Lyme disease. This is why using IgM as a base when testing for Lyme disease will only help if the person has an active infection.

Although both IgM and IgG antibodies are needed to respond to certain infection-driven illnesses, they do so in their own ways that benefit the health of the body in both the short term and long term.

Types Of Lyme Disease Tests

Antibody titer tests for Lyme disease measure antibodies that are specific to the bacteria that can trigger the condition. Antibodies are part of the bodys immune response. Tests look for two types of antibodies, known as immunoglobulin M and immunoglobulin G .

IgM antibodies usually peak within a few weeks after an infection with Borrelia bacteria and start to collapse 4-6 months after infection. IgG antibodies are slower to develop, beginning to show 4-6 weeks after exposure and may peak 4-6 months after exposure. While IgM tends to be associated with an active infection, both IgM and IgG can persist in the blood for many years.

The Centers for Disease Control and Prevention recommends a two-stage or two-tiered test for these antibodies. If the initial blood test is positive for IgM or IgG antibodies associated with the Borrelia bacteria, a second test is done, often using different laboratory methods.

Testing for IgM and IgG can support the finding that you have been exposed to Borrelia, but this on its own does not prove whether or not you have Lyme disease.

Follow-up testing may be necessary if testing is inconclusive. This could involve repeat blood tests or the use of different types of medical tests to rule out other health conditions. In people suspected of bacterial reinfection, imaging tests may be used to detect joint inflammation.

My Child Had Lyme Disease Got Treated And Is Now Depressed Could This Be A Sign Of A Relapse

IgM and IgG antibodies represent different stages of an immune response against COVID-19

Depression is a word that encompasses physical, cognitive, and emotional components. The physical would be poor sleep, fatigue, low energy, lack of sex drive. The cognitive would include poor concentration and trouble making decisions. The emotional would include feeling guilty, hopeless, suicidal, and being unable to enjoy life in any aspect. Chronic symptoms triggered by Lyme disease are most often associated with insomnia or hypersomnia, fatigue, headaches, pain, and, not uncommonly, problems with cognition as well. In other words, chronic Lyme symptoms are most often associated with the physical and cognitive parts of the depressive picture and less often with the emotionally despairing part. When a person presents with the emotional part that is sustained for at least 2 weeks, it may be that a full syndrome depression has emerged related to the Lyme disease or that it is a concurrent but unrelated illness. The emotional aspects of depression might occur secondarily to being sick with a physical illness or directly from an infection affecting the brain or from chemicals affecting the brain that were released by infection outside of the brain. When a person has Lyme encephalitis , the emotional part of depression can be very dramatic. The person might be suddenly tearful for no apparent reason, have very poor frustration tolerance, become paranoid or angered at the least provocation, and appear to have a personality change.

What Does A Positive Lyme Igm Mean

The IgM antibodies are the first antibodies to be produced in the body in response to an infection. IgM antibodies are larger than IgG antibodies and when present in high numbers, may indicate a recent or new active infection. In short, a positive IgM may be a sign of a current, or very recent, infection.

Lyme Disease Antibody Test Procedure

The Lyme disease antibody test requires no advance preparation. A lab technician will swab the inside of your elbow with an antiseptic before drawing your blood. Your blood will be drawn from a vein in your arm using a small needle.

The blood draw should not be painful, though you might feel a slight prick when the needle is inserted into your vein.

The blood sample will be collected in a vial. The puncture site will be bandaged, if needed, after the needle is removed. After the blood draw, you are free to go home.

There are very few risks associated with the Lyme disease antibody test. Excessive bleeding is possible, but there may be an increased risk if you take blood thinning medications or certain anti-inflammatory drugs like:

  • heparin

What Is Immunoglobulin M

Antibodies are large proteins of the immune system that neutralize intruders, such as bacteria, viruses, fungi, and parasites. There are five main types of antibodies: IgA, IgD, IgE, IgG, and IgM.

IgM are the largest antibodies. They are the first-line defense of our immune system. They provide general but short-term protection against new infections. IgM levels decline as the body starts producing more IgG antibodies, which are responsible for long-term protection against pathogens .

Apart from immune IgM antibodies, which are produced in response to infections, we also have natural IgM antibodies that circulate in the blood without exposure to any intruders . These are responsible for removing damaged and pre-cancerous cells, thereby also decreasing inflammation and protecting us from autoimmunity .

Key Points To Remember

  • Most Lyme disease tests are designed to detect antibodies made by the body in response to infection.
  • Antibodies can take several weeks to develop, so patients may test negative if infected only recently.
  • Antibodies normally persist in the blood for months or even years after the infection is gone therefore, the test cannot be used to determine cure.
  • Infection with other diseases, including some tickborne diseases, or some viral, bacterial, or autoimmune diseases, can result in false positive test results.
  • Some tests give results for two types of antibody, IgM and IgG. Positive IgM results should be disregarded if the patient has been ill for more than 30 days.

Coinfection With Other Tick

Ixodes ticks have a broad host range, therefore increasing the chance of acquiring multiple pathogens from reservoir hosts. This suggests that patients with one documented tick-transmitted disease may be at increased risk for infection with other tick-transmitted microorganisms. In Wisconsin, a study of 96 patients with a primary diagnosis of LD demonstrated immunoserologic evidence of coinfection with Babesia microti and/or Ehrlichia phagocytophila in 9.4% . In addition to ehrlichiosis and babesiosis, coinfection with tick-borne encephalitis virus is a possible consideration for LD patients in Europe. Infection with multiple agents could explain, at least in part, the variable manifestations and clinical responses reported in some patients with LD and may have confounded our understanding of the true clinical spectrum of the disease. As a practical consideration, laboratory testing for coinfection should be considered in some clinical situations to ensure that appropriate antimicrobial therapy is prescribed.

Statistical Analyses And Cutoff Calculations

To normalize for anticipated daily variation of the assay measurements, duplicate positive control wells employing a reactive serum control against rBBA73 were included on each plate. Optical density values were normalized by dividing all OD values on the plate by the positive plate controls’ average OD. Exploratory analysis showed relatively little variance attributable to user or date replications, therefore sample replicates were averaged over these prior to further analysis. Natural logarithms of the normalized values were computed for use as the primary measure in analyses .

Upon closer examination of the original data, six of the healthy endemic samples had abnormally high OD values. A follow-up principal components analysis indicated that these samples were indeed outside of the normal range for a typical healthy endemic and so were excluded as controls.

What Can Patients With Chronic Neuropsychiatric Symptoms From Lyme Disease Do To Get Proper Treatment If We Are In A So Called Non

Antibody Testing: IgG and IgM explained

Chronic neuropsychiatric Lyme disease is a confusing entity to treat. That is why it is best to consult with someone who has had considerable experience evaluating these patients. That specialist may then be able to guide you and your doctor regarding the next phase of treatment. For example, while one patient may need additional antibiotics, another may need symptomatic therapies focused more on the residual symptoms. If one lives in an area in which Lyme disease is not common, it can be helpful to ask your doctor whether he or she would consider it useful for you to consult with a doctor from another state who might be more familiar with the latest treatment strategies. Most doctors would appreciate the recommendation of a colleague with more extensive expertise. It helps both the treating doctor and the patient. Your doctor may also wish to call a specialist in another state who has more experience often informal professional to professional consultation is quite helpful. We wish to add however that we have seen many patients who have avoided going to regular doctors or regular psychiatrists because of a fear of being misunderstood. This can be risky because it delays help which that particular doctor may be able to provide. One does not necessarily need to be an expert on neuropsychiatric Lyme disease to treat depression or irritability related to Lyme disease.

Are There Any Diseases That Can Be Misdiagnosed As Lyme Disease

Lots of diseases could be misdiagnosed as Lyme disease. This of course makes sense when you know that Lyme disease itself may manifest as a multisystemic disorder that can mimic other diseases. This means that just as the Lyme disease might be “missed” in some cases, some individuals may be misdiagnosed as having Lyme disease when in fact they have another disease. Erring on either side of this diagnostic divide can be dangerous. Given that the main symptoms that afflict patients with Lyme disease are fatigue and pain and given that these are non-specific symptoms seen in a wide ranges of diseases, including cancer, hematologic, and endocrine disorders, one has to make sure to rule out other reasonable causes of fatigue and pain before making the diagnosis of Lyme disease. It is also important to realize that a patient can have two independent diseases – Lyme disease and another emergent condition. For example, concurrent depression,sleep apnea or hypothyroidism may exacerbate fatigue in a patient with actual Lyme disease.

Is It Possible For Lyme Disease To Be Misdiagnosed As Amyotrophic Lateral Sclerosis Are There Similarities In Symptoms Between These Two Diseases

The question of a relationship between Lyme Disease and ALS first received significant academic attention when Dr. John Halperin who was then a neurologist at Stony Brook conducted a study in which he compared the frequency of blood test positivity to the agent of Lyme disease among patients with ALS to community controls. The results indicated a higher percentage of the ALS patients were seropositive for Lyme Disease. Since then, there have been isolated case reports both in the media and one or two in the academic literature indicating that a patient had been misdiagnosed with an ALS-like illness only later to be re-diagnosed and treated for Lyme disease with good clinical response. Although we suspect that there may be rare individuals who have symptoms similar to ALS but actually have proximal motor neuropathy caused by Lyme disease, the vast majority of patients with ALS are not thought to have Lyme disease as the cause of their serious disease. Clinical trials have been underway using antibiotics for ALS not because there is belief that ALS is caused by a microbe but because these antimicrobial agents have other properties as well, such as decreasing inflammation or decreasing glutamatergic excitotoxicity. The studies examining intravenous ceftriaxone as a treatment for ALS were not successful.

Specialty Lyme Testing Labs: Are They Worth It?

If the symptoms of Lyme disease persist and there is no known cause for them, then consulting with a Lyme literate doctor may provide treatment progress. Many health insurance plans will not cover these consultations or tests, however, so proceed with caution.

For those who are treated with antibiotics, a condition called PTLD occurs that mimics the symptoms of the disease for up to 6 months.

In regions where Lyme disease is not prevalent, it is usually up to the patient to insist on receiving the Lyme disease blood test. Use this guide to speak with your doctor about your concerns and discuss what the results may mean for your health.
