DEFINISI :
Hepatitis = keradangan hati
PENYEBAB :
1. Infeksi : parasit (malaria, amoeba),
bakteri (tbc, banal), jamur,
viral (hepatitis A, B, C, D, E, F, TT, CMV, EBV)
2. Kerusakan hati : alkohol, obat-obat (asetaminofen, metildopa, INH, fenitoin, valproat, CPZ, amiodaron, TMP-SMZ, eritromisin), bahan beracun
3. Autoimun
4. Fibrosis kistik
5. Penyakit Wilson : deposit Cu berlebihan dalam hati

RIWAYAT RINGKAS HEPATITIS B.
SAKIT KUNING : (+) sjk abad 5 SM di Babilonia.
Hippocrates (460-375 SM) icterus infectiosa menular >< imunisasi.
Letupan wabah di kalangan militer :
- Franco-Prussian War (1870) - Perang Boer (1948)
- Perang Korea (1952) - Perang Timur Tengah (1956)
Lurman (1885) : epidemi hepatitis virus di Bremen dengan transmisi parenteral.
Water viral hepatitis, wabah di : Inggris (1895), Skandinavia (1916, 1944), New Delhi
(1955-1956).
Flaum (1926) : epidemi hepatitis virus pada penderita DM yang mendapat obat suntikan.
Blumberg BS (1977) : penemu virus hepatitis B (HBV) Australian antigen = HBsAg (Lihat gambar I.).
Adi Teruna Effendi (1982) : Hepatitis virus merupakan penyakit jabatan pada kalangan
profesi kesehatan, risiko tertular lebih tinggi 2-10 kali dibanding populasi umum.
New York State Workmens Compensatoir Bureau (1984) : mengakui hepatitis virus sebagai penyakit jabatan pada kelompok petugas kesehatan

Prevalence of HBV
Hepatitis B virus (HBV) is one of the worlds most common infectious diseases
Around 400 million people have chronic HBV
infection
> 1 million people die every year of HBV-
related chronic hepatitis, cirrhosis or liver
cancer
WHO 1998; Lai et al Lancet 2003
-
1. Penemuan pertama kali jenis infeksi, dengan sebutan virus hepatitis Non-
A Non-B dan didukung pembuktian klinis 2. Diidentifikasi sebagai virus hepatitis C (HCV) dan dikembangkan di
California tahun 1988.
3. Gambaran klinis berhubungan dengan riwayat transfusi darah, dengan masa inkubasi 2-26 minggu. 4. HCV : virus dengan amplop ukuran 50 nm genom RNA positif mengandung 9400-9500 nukleotida, mirip Flavivirus dan Pestivirus
(PRINCE,et al.1974; FEINSTONE,et al.1974

FAKTOR RISIKO HEPATITIS
VIRAL KRONIK
1. IDU (pemakai obat suntik), Tatoo
2. Overdosis asetaminofen, alkohol atau obat lain
3. Kebiasaan seksual risiko tinggi / freesex
4. Terkontaminasi : family, travel, eating, living
5. Resipien : - transfusi darah sblm th. 1990, - transplantasi organ
6. AIDS
7. Bayi dengan ibu pengidap Hepatitis B atau C
