HIV and Hepatitis B (HBV) - POZ
(8) However, in general, knowledge of the HBV genotype is not consistently .. Hepatitis B in patients with HIV infection: relationship to AIDS and patient survival . Hepatitis B virus (HBV) is an infection that can cause severe liver damage. Between 5 and 10% of people living with HIV also have hepatitis B virus, known as. Vaccination is the best way to protect against all of the ways that HBV is transmitted. No vaccine exists for HCV. The best way to prevent HCV.
Heplisav-B is given in two doses, one month apart. Two older HBV vaccines are available: Recombivax HB and Engerix-B.
Both vaccines require three injections administered over a six-month period. The side effects of the hepatitis B vaccine are usually mild and may include soreness at the injection site and mild flulike symptoms.
There is also a combined hepatitis A HAV and HBV vaccine available Twinrixwhich also requires three injections administered over a six-month period but offers the added advantage of providing protection against both viral infections.
In clinical trials, Heplisav-B was effective 95 percent in adults. People with compromised immune systems may be less likely to develop immunity to HBV through vaccination.
If you do not think you were ever infected with hepatitis B, talk to your health care provider. The vaccine is recommended for: For hemodialysis patients, the need for booster doses should be assessed by yearly testing for hepatitis B surface antibody anti-HBs.
For immunocompromised persons, the need for booster doses has not been well researched. Hepatitis B booster doses are not recommended for people with normal immune status who have been vaccinated.
If you have not been vaccinated against hepatitis B, there are still things you can do to prevent HBV infection.

These include using a condom or another type of latex barrier while having sex. If you are an injection drug user and share equipment, cleaning your syringes with bleach will not help you avoid hepatitis B. If you have not been vaccinated against hepatitis B and fear that you were recently exposed to HBV, it is possible to receive a single injection of hepatitis B immune globulin HBIG.
HBIG is recommended following exposure to hepatitis B virus because it provides immediate, short-term protection against the virus. Chronic active hepatitis B exacerbations in human immunodeficiency virus-infected patients following development of resistance to or withdrawal of lamivudine.

Using a condom reduces the chance of HBV being passed on during sex. Syringes and other injecting drug equipment should never be shared.
It is also possible to acquire hepatitis B through personal care items such as razors, toothbrushes and manicure tools that come into contact with blood. These items should not be shared. New, sterile needles should be used for piercings, tattooing and acupuncture.
Hepatitis B is not transmitted through normal social contact such as sharing crockery or cutlery, or touching someone with hepatitis B.
Blood spills from someone with hepatitis B should be cleaned up following sensible infection control procedures e. Scratches, cuts and wounds should be cleaned with soap and water and covered with a waterproof dressing or plaster.
In countries where hepatitis B is most common, many people acquired it through mother-to-child transmission or during early childhood.
The best protection against acquiring hepatitis B is the HBV vaccine. Infection rates in many countries have fallen dramatically thanks to routine infant hepatitis B vaccination. It is important that people living with HIV, hepatitis C or any other liver disease get vaccinated against hepatitis B if they are not already immune. Stages of infection Most people who get hepatitis B as adults will naturally clear the virus without treatment. However, babies, children and people with weak immune systems including those with HIV will go on to have chronic infection infection lasting beyond six months.
People who naturally clear the virus recover fully and develop lifelong immunity that prevents them from getting HBV again. However, hepatitis B genetic material DNA remains inside liver cells and, on rare occasions, it may reactivate later, especially if the immune system becomes weakened.
There are four stages of chronic hepatitis B infection: Stage 1 — immune tolerance: During this stage, HBV reproduces freely in the body and viral load is high, but the immune system is not responding strongly to the infection.
In adults, this stage is usually short-lived, but it can last for years or decades in people who acquired HBV as babies.
