Get Rid Of Herpes Antibodies

Past Prophylactic Vaccine Trials Against Hsv

Herpes Simplex Virus Treatment / Alynn Alexander, MD

In the past decade or so, two prophylactic vaccines for the prevention of genital herpes have been tested for efficacy and safety in large phase III clinical trials. Both vaccines were subunit vaccines targeted against either HSV-2 glycoprotein B and D or glycoprotein D alone. Both vaccines induced high serum titers of HSV neutralizing antibody, and HerpeVac also elicited Th1 responses . Despite this, the Chiron vaccine showed no efficacy in prevention of either disease or infection with HSV-2 in enrollees . Furthermore, no difference was observed between the control and vaccinated groups in the duration of the first episode of clinical symptoms or in the recurrence of disease . The first HerpeVac study found that while men were unprotected by the vaccine, 74% vaccine efficacy was observed in women from discordant couples who were seronegative for both HSV-1 and HSV-2 . However, a follow-up study with the same vaccine in a generalized group of women seronegative for both HSV-1 and -2 found no protection against HSV-2 infection or disease, although a higher rate of efficacy was observed against HSV-1 . Currently, no vaccines are available for the prevention of genital herpes caused by HSV-2.

If You Get A Positive Result Don’t Panic It Really Doesn’t Mean Much

All of this is to say that unless you have symptoms consistent with the herpes virus, why put yourself through the emotional turmoil of getting a blood test that may or may not give you legit results? As Hutcherson notes, if you do get a blood test and it comes back positive but you’re asymptomatic, what does that mean for you if you have nothing to treat? For many, due to the high rate of stigma still surrounding herpes, it can mean feelings of self-contempt, humiliation, and distress, all of which could be avoided if you aren’t experiencing any symptoms.

To recap, while there are some tests for herpes that can prove correct, none are 100 percent perfect, and blood tests are particularly problematic since they can produce false positives and negatives. We also know that the majority of the population has some form of herpes, so IMO it’s a mystery as to why we’re still making a big deal out of it. No one likes blisters or sores, but neither does anyone love having acne, a widespread condition without the same level of attached shame.

Why The Test Is Performed

The test is done to find out whether a person has ever been infected with oral or genital herpes. It looks for antibodies to herpes simplex virus 1 and herpes simplex virus 2 . An antibody is a substance made by the body’s immune system when it detects harmful substances such as the herpes virus. This test does not detect the virus itself.

Can I Still Have Sex If I Have Herpes

If you have herpes, you should talk to your sex partner about their risk. Using condoms may help lower this risk but it will not get rid of the risk completely. Having sores or other symptoms of herpes can increase your risk of spreading the disease. Even if you do not have any symptoms, you can still infect your sex partners.

You may have concerns about how genital herpes will impact your health, sex life, and relationships. While herpes is not curable, it is important to know that it is manageable with medicine. Daily suppressive therapy can lower your risk of spreading the virus to others. Talk to a healthcare provider about your concerns and treatment options.

A genital herpes diagnosis may affect how you will feel about current or future sexual relationships. Knowing how to talk to sexual partners about STDs is important.

How Soon Can You Be Tested

PPT

The incubation period for herpes is 2 to 12 days, which means that the best time to get tested for the herpes virus if you havent had an initial outbreak is after 12 days. If youre worried that youve been exposed to herpes but have not yet been diagnosed, here are some steps you can take:

  • If youre currently sexually active, stop all sexual activity until you can receive a formal diagnosis.
  • Reach out to your doctor and schedule an appointment for once the incubation period is up.
  • If youre having an outbreak, you dont have to wait to get tested. Its possible to receive a diagnosis based on the lesions.

Testing With No Symptoms

Blood tests can be used when a person has no visible symptoms but has concerns about having herpes. Blood tests do not actually detect the virus instead, they look for antibodies in the blood.

IgM vs. IgG

When an individual contracts herpes, the immune system responds by developing antibodies to fight the virus: IgG and IgM. Blood tests can look for and detect these antibodiesnot the virus itself. IgG appears soon after infection and stays in the blood for life. IgM is actually the first antibody that appears after infection, but it may disappear thereafter.

IgM tests are not recommended because of three serious problems:

The accurate herpes blood tests detect IgG antibodies. Unlike IgM, IgG antibodies can be accurately broken down to either HSV-1 or HSV-2. The challenge here is that the time it takes for IgG antibodies to reach detectable levels can vary from person to person. For one person, it could take just a few weeks, while it could take a few months for another. So even with the accurate tests, a person could receive a false negative if the test is taken too soon after contracting the virus.

For the most accurate test result, it is recommended to wait 12 16 weeks from the last possible date of exposure before getting an accurate, type-specific blood test in order to allow enough time for antibodies to reach detectable levels.

Can Genital Herpes Be Prevented

Practising safe sex is the best way to help prevent genital herpes infection.

It is safest to:

  • always use condoms and dental dams, even when there are no sores or blisters present
  • avoid sex when there are sores or blisters present you are most infectious at this time
  • avoid sex with someone who has any blisters, sores or other symptoms of genital herpes
  • avoid oral sex when there is any sign of a cold sore

If You Have Genital Herpes Already Can It Be Spread To Other Parts Of The Body Such As The Arms Or Legs

Understanding Genital Herpes

No. Genital herpes cannot be transmitted to another part of your body such as your arm, leg or hand after the first infection occurs. If you have genital HSV II, you will not get HSV II at another site in your body. The immune system produces antibodies that protect other parts of your body from infection. However, there are cases where a person has multiple site infections from the same virus. This is usually acquired at the time of the first infection. For example, if someone has never had herpes but then has oral and genital sex with an infected partner, they can acquire the infection at both sites.

I Tested Positive For Herpes What Should I Do Now

For most people, having herpes does not affect their health or quality of life. To prevent passing on cold sores and genital herpes to others, a person can:

  • avoid kissing others when the virus is active
  • use condoms when having sex
  • avoid skin-to-skin contact during an active outbreak
  • avoid sharing towels, toothbrushes, and lipstick when they have sores around the mouth
  • wash their hands well after touching a sore

Having multiple sexual partners can increase the risk of

transmitting STIs such as herpes. People can decrease this risk by openly discussing STI status and prevention with any partners and practicing safe sex.

  • If HSV affects your mouth, you might have difficulty eating spicy or acidic foods while you have open sores.

Theres also a slight difference in where oral blisters appear, depending on whether theyre primary or recurrent. During the first episode, blisters may appear on your mouth and lips, but during later episodes, theyre more likely to

Is There A Cure Or Treatment For Herpes

Theres no cure for the herpes virus yet. A herpes vaccine doesnt currently exist, as the herpes virus has more complicated DNA than most infections, creating challenges for researchers.

However, medication can help with symptoms, like sores, and outbreaks. Medication also lowers the risk of transmission to others. You can take most medications for herpes orally, though you may also apply some as a cream or receive them by injection.

Symptoms Of Genital Herpes

PPT

Many people who have genital herpes may not be aware they have the infection, because they may not have any symptoms.

The first episode of herpes can cause considerable pain and distress. Symptoms of the first episode may include:

  • flu-like symptoms such as feeling unwell, headaches and pains in the back and legs, with or without enlarged glands in the groin
  • small blisters around the genitals these break open to form shallow, painful ulcers, which scab over and heal after one to two weeks
  • small cracks in the skin with or without an itch or tingling
  • redness or a distinct rash
  • some people also have considerable pain and swelling in the genital area, and hence may have additional pain and difficulty passing urine.

Signs And Symptoms Of Herpes

Both kinds of herpes cause outbreaks of painful sores on the skin. Symptoms of herpes include:

Oral herpes sores

Sometimes called cold sores, HSV-1 produces painful sores that look like blisters at first. They eventually burst and crust over. It usually takes a week to 10 days for the sores to clear up.

Genital herpes sores

The sores that appear in the genital area can come from HSV-1 or HSV-2. Like the sores on the mouth, they start as painful blisters, then dry up and heal over time.

Other sores

Although they usually show up around the mouth or genitals, herpes sores can appear anywhere on the body.

Flu-like symptoms

During a herpes outbreak, you might feel other symptoms such as fever, tiredness, or body aches.

Not all people who have herpes have frequent outbreaks. Some people might have a single outbreak then never show symptoms again. The virus may stay dormant in their body.

How Do Dermatologists Diagnose Herpes Simplex

During an outbreak, a dermatologist often can diagnose herpes simplex by looking at the sores. To confirm that a patient has herpes simplex, a dermatologist may take a swab from a sore and send this swab to a laboratory.

When sores are not present, other medical tests, such as blood tests, can find the herpes simplex virus.

How Common Is Genital Herpes

According to the Centers for Disease Control and Prevention, approximately 40 million to 50 million adults in the United States have genital herpes. HSV II infection is more common in women and in people who have had more than five sexual partners. Most people with HSV II do not know they have it, because it does not always cause symptoms.

Type Of Tests Used To Diagnose Herpes

Goodfellow Unit MedTalk: Can HPV vaccines eliminate genital warts

There are four main types of diagnostic tests that can be used to diagnose herpes. Your doctor will determine which type of test to use based on whether an outbreak is present or not.

If youre experiencing what you believe to be a herpes outbreak, your doctor can use a viral culture test or virus antigen detection test. If youre not experiencing symptoms, you can have an antibody test.

  • Viral culture test.This test is used to determine if a sore contains the herpes virus. This test can sometimes produce a false-negative, meaning that it may not detect the virus even though its present.
  • Virus antigen detection test. This test is used to determine if antigens to the herpes virus are present in a sore or lesion.
  • Antibody test. If youre not experiencing an outbreak yet but still believe you may have been exposed, you can opt to have an antibody test performed. This test will only show a positive result if the antibodies to the virus have been developed. Therefore, this test isnt necessarily recommended for recent exposure.
  • Polymerase chain reaction test. With this test, a healthcare provider can screen a sample of your blood or tissue from a sore. They can use this to determine if HSV is present and which type you have.

Herpes Virus Cleared From Blood For First Time

By Linda Geddes

A COMMON virus that can reduce lifespan and cause blindness has been cleared from human blood for the first time.

Cytomegalovirus , a type of herpes virus, is carried by about 70 per cent of people and, although it usually doesnt cause illness, shaves 3.7 years off life expectancy.

In people with a weakened immune system, however, the virus awakens and can cause serious illness and blindness. This can be a particular problem if the only available donor for a bone marrow transplant is infected with CMV and the recipient is not.

CMV only expresses a handful of genes when it is dormant. One of them is UL138. To investigate what it does to cells, Michael Weekes at the University of Cambridge and colleagues grew healthy human cells alongside cells that were made to express UL138 in the presence of labelled amino acids the raw ingredients used to make proteins. They then used mass spectrometry to identify how UL138 changed the cells expression of proteins.

We know that viruses remodel the landscape at the surface of the cell, so weve been asking what proteins are on the cell surface and how does CMV change that?’ says Paul Lehner, also at Cambridge, who supervised the work. CMV appears to dampen the production of a protein called MRP1 that pumps toxic chemicals out of cells including the cancer drug vincristine. If infected cells can no longer pump out vincristine, perhaps this would kill them while sparing healthy cells that remove the poison?

What Are The Different Types Of Herpes

There are two types of herpes simplex virus: HSV I and HSV II. HSV I commonly causes oral herpes, or cold sores. This virus can show up as an upper respiratory tract infection during early childhood. HSV II is the cause of most cases of genital herpes. However, it is possible for HSV I to cause genital herpes and HSV II to cause oral herpes.

Clinicians cannot tell the difference between the two types by physical examination alone, but there are differences between the two viruses. For example, genital herpes caused by HSV II is much more likely to recur. This diagnosis can be helpful in establishing a health care plan.

How Does Genital Herpes Spread

Herpes can be spread when an infected person has lesions blisters and open sores on their body or when you do not have any symptoms. Taking antiviral medicine can help you reduce the risk of spreading genital herpes to your sexual partners. You can also:

  • Inform your sexual partner that you have genital herpes.
  • Use a condom every time you have sex.
  • Refrain from having sex when you have symptoms.
  • Abstain from performing oral sex if you have blisters or open sores around your mouth.

If You Have Zero Symptoms Getting Tested Won’t Help You

The problem is that blood tests for herpes when no lesions or symptoms are present are often bullshit. I realize that’s a pretty strong word, but after speaking with doctors who have administered these tests, it’s become more and more apparent to me how misunderstood and in some cases, just plain wrong the results they give are.

Part of the reason they’re flawed has to do with the fact that most people have been exposed to HSV-1 or oral herpes. “For HSV-1, close to 100 percent of people in the U.S. are antibody-positive because they have been exposed at some point in their lives, though only a percentage of these individuals will actually get cold sores,” says Adam Friedman, the residency program director at the George Washington University School of Medicine & Health Sciences in Washington, D.C. He adds that blood tests can be misleading because they usually don’t detect the herpes virus itself and instead look at the level of antibodies against the virus, which is merely a sign of immune response to it.
