Acute fatty liver of pregnancy:
![Page 2: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/2.jpg)
• -AFLP is a rare condition
• -unknown etiology
• -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD) deficiency).
![Page 3: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/3.jpg)
• - It has an incidence in various studies of between 1 in 7000 and 1 in 13 000 pregnancies.
• - It is frequently fatal for the mother and baby unless there is a speedy diagnosis and the correct treatment is given.

• Clinical manifestation :• - an obese woman will present with
vomiting and a headache in her third trimester.
• - She will quickly complain of malaise and severe abdominal pain, followed by jaundice and drowsiness.
• -50% of these women have symptoms of pre-eclampsia (hypertension and proteinuria),
![Page 5: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/5.jpg)
• -the pre-eclampsia will mask the presentation of AFLP.• liver is tender but not enlarged• diagnosis:• -an ultrasound• -computerized tomography (CT) scan of the liver
demonstrates fatty infiltration. -Liver biopsy is contraindicated owing to the risk of coagulopathy.
• -The liver enzymes are moderately raised and the woman will also quickly show -renal failure (liver function test )
• -blood glucose level (hypoglycemic.)
![Page 6: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/6.jpg)
• Management :• -correcting any coagulopathy : infusing fresh
frozen plasma.• - The woman must be delivered immediately.• -Caesarean section is said to have many
advantages for the baby, but it is safest for the mother to birth vaginally if this is possible.
• - Epidural analgesia is contraindicated in all .• -Convalescence is prolonged but usually
complete.• -recurrence rate is low.

•Gall bladder disease• -Pregnancy appears to increase the likelihood of
gallstone formation but not the risk of developing acute cholecystitis.
• Diagnosis of gall bladder disease is made by :• 1-listening to the woman's previous history• 2- an ultrasound scan of the hepatobiliary tract
or both.

• * analgesia, hydration, nasogastric suction(compression ) and antibiotics.
• Surgery should be avoided if at all possible.

•Viral hepatitis:
• Viral hepatitis is the most common cause of jaundice in pregnancy.
• - Acute infection 1 in 1000 pregnancies
• - an incubation period of 1–6 months.
![Page 11: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/11.jpg)
• Symptoms include :• -nausea• - Vomiting• - anorexia• - pain over the liver• - mild diarrhea • -jaundice lasting several weeks• -malaise.• - Fever is rare.• - the disease is asymptomatic, or mimics mild
influenza

• Method of transmission :
• -blood, blood products.
• - sexual activity.
• - The virus can also be transmitted across the placenta.
![Page 13: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/13.jpg)
•-Hepatitis B :
• -is more common in tropical and developing countries.
• -poor nutrition.• - limited use of contraception barrier)• -injecting drug users who share needles • -The more common infections are known as
hepatitis A, B ,C ,D and E
![Page 14: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/14.jpg)
• **Hepatitis A (HAV):• -acute infection • -transmitted by ingesting water contaminated .• - It is endemic worldwide.• - Mother to baby transmission is rare but can occur
at birth.• - HAV is a self-limiting illness results in complete
recovery. • -Vaccination is available.• - Strict hygiene• -hand washing ,reduces the risk of cross infection
![Page 15: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/15.jpg)
• Hepatitis B (HBV) :
• -serious infection.
• - 5–10% of those infected become chronic carriers.
• - 25–30% of these will die.
• - 0.5–5% of the population are chronic HBV carriers.
![Page 16: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/16.jpg)
• - test for the HBV surface antigen (HBsAg).
• - adults 90% cases of HBV resolve completely within 1–3 months.
![Page 17: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/17.jpg)
• -complications of HBV:
• transplacental passage of the virus and through blood and body fluids at birth.
• 1-increased risk of chronic liver disease.
• 2-cirrhosis
• 3-primary liver cancer in later life.
• -Caesarean section does not prevent mother to fetus transmission.
![Page 18: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/18.jpg)
• Diagnosis :
• history of her symptoms and lifestyle.
• Serological studies, but it can be difficult to distinguish hepatitis B from other forms of viral hepatitis during the acute presentation, before antibodies have formed
![Page 19: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/19.jpg)
• Treatment :
• Symptoms
• Infection control measures ,the woman is considered to be infectious.
• Education about the disease, nutrition and sexual advice, should be offered. -Liver function will be monitored
![Page 20: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/20.jpg)
• Assess fetal condition. • Household contacts should be offered
immunization after their HBsAg was done . • -Sexual partners should testing and giving
vaccination.• Postnatally the mother will be encouraged to
accept vaccination for the baby. Breastfeeding is permitted

Hepatitis C virus (HCV): risk factors for transmission
are blood and blood products.the use of shared intravenous needles.

Pregnancy and liver transplantation:
![Page 25: Acute fatty liver of pregnancy:. -AFLP is a rare condition -unknown etiology -(although fetal long-chain hydroxyacyl co-enzyme A dehydrogenase (LCHAD)](https://reader036.vdocuments.mx/reader036/viewer/2022070401/56649f205503460f94c38fe8/html5/thumbnails/25.jpg)
– -liver transplantation done before or during pregnancy, many with successful outcomes.
– -Although not desirable.– - liver transplantation in women of childbearing
age is becoming possible -women require expert medical and midwifery care at a specialized centre

Ready to deal with all of the complications, both of a physical and psychological nature
