Prophylaxis of Hepatitis B and Hepatitis D

Hey guys!
Guess what? I did an amazing microbiology seminar today on this topic..
So thought of posting it on the blog as well :D

Prophylaxis of Hepatitis B

Avoid sharing personal items

• Don't share needles, razors, toothbrushes, manicure tools or other items that could bear contaminated blood.. [Don't share a bloody thing! ;)]

• Don't allow yourself to be pierced or tattooed with non-sterile equipment

• Make sure your barber uses clean razors, manicure and pedicure items

Behavior Modification

• Use a new latex or polyurethane condom every time you have sex, particularly if you have multiple sex partners.

Limit alcohol intake. [Love your liver :) ]

• If you are a medical professional, follow good practices for using and disposing of needles. [Or a wanna be doc like me!]

Passive Immunoprophylaxis

•  Hepatitis B Immune Globulin (HBIG) is a sterile solution of ready-made antibodies against Hepatitis B

• HBIG is prepared from human blood from selected donors who already have a high level of antibodies to Hepatitis B and used in passive immunoprophylaxis

• Passive immunoprophylaxis is used in:
  • Newborns of mothers infected with Hepatitis B
  • After liver transplantation
[I know you are probably wondering why liver transplant! See sometimes as a last resort to Hepatitis you need to get a liver transplant.. So better not get infected with the same virus again eh?]

Active immunization

• The vaccine contains one of the viral envelope proteins, Hepatitis B surface antigen (HBsAg).

• It is produced by yeast cells, into which the genetic code for HBsAg has been inserted.

• Three doses of vaccine are required to achieve effective immunization

[I know most of you haven't got a vaccine against Hepatitis B yet.. So get vaccinated please!]

Mixed Immunization

Infants born to mothers infected with Hepatitis B virus should be treated with Hepatitis B immune globulin and hepatitis B vaccine within 12 hours of birth, with the second and third doses of vaccine given at one and six months of age.

Prophylaxis of Hepatitis D

• Hepatitis D only occurs in those who have hepatitis B

• Hepatitis D virus depends on HBV to develop, all the preventing measures that someone can take are regarding also the prevention against Hepatitis B virus

• So the vaccine against Hepatitis B, prevents both Hepatitis B and Hepatitis D infection

• Unfortunately, there is no vaccine available against the hepatitis D virus for people who are already infected with hepatitis B virus

Thats all.. Thank you so much for visiting & reading.. I appreciate all your support! ^_^
Have a rocking weekend \m/
