IntroductionIntroductionLiver disease is a rare complication of Liver disease is a rare complication of pregnancy, but when it occurs it may pregnancy, but when it occurs it may do so in a dramatic and tragic fashion do so in a dramatic and tragic fashion for both mother and infant. Diseases for both mother and infant. Diseases such as acute fatty liver of pregnancy such as acute fatty liver of pregnancy (AFLP) may begin (AFLP) may begin gradually gradually with mild with mild symptoms and liver enzyme symptoms and liver enzyme abnormalities but, if left untreated, abnormalities but, if left untreated, can progress to jaundice, liver failure, can progress to jaundice, liver failure, and death.and death.

• Telangiectasia, particularly on the chest, Telangiectasia, particularly on the chest, back, and face, and palmer erythema back, and face, and palmer erythema occur in up to 60 percent of normal occur in up to 60 percent of normal pregnant women but disappear after pregnant women but disappear after deliverydelivery..

Anatomic Changes:Anatomic Changes:

• Liver weight increases during pregnancy has not Liver weight increases during pregnancy has not been documented. Liver size is difficult to been documented. Liver size is difficult to estimate in pregnancy, but records fail to show estimate in pregnancy, but records fail to show any substantial increase in liver weight in any substantial increase in liver weight in comparison with nonpregnant controls.comparison with nonpregnant controls.

• Therefore, detection of hepatomegaly is strong Therefore, detection of hepatomegaly is strong

Summary of physiologicalSummary of physiological and biochemical and biochemical changes in the changes in the liver during pregnancyliver during pregnancy

• Increased:• Alkaline phosphatase levels rise threefold or fourfold due to• placental production• Clotting factor changes create a hypercoagulable state• Decreased:• Gallbladder contractility• Uric acid levels• Albumin, total protein, and antithrombin III concentrations

• No change:• Liver aminotransferase levels (aspartate

rises only in liver injury), gamma-glutamyl transferase)

incidences : vary and appear to be ethnic and familial prediction and the risk increase among-obesity, nulliparity, and twin gestation.

hospitalization rate is about 0.5-0.8 % and with those have previous history up to 20% require hospitalization.

Pregnancy-Unique Quantification of Emesis/Nausea (PUQE) index: Total score is sum of replies to each of the three questions. Nausea Score: Mild NVP = ≤6; Moderate NVP = 7–12; Severe NVP = ≥13

•Etiology:- High or rapid rise in serum level of pregnancy related hormones (HSG,E2, progesterone,placental growth hormone, prolactin,thyroxine and adreno-cortical hormone)-There is some studies implicated psychological component - for unknown reason a female fetus increase the risk by 1.5 folds.

• There is small evidence for the association between hyperemesis and H.pylori infection.

• Complications: - Acute renal failure from dehydration , and

may require 5 day dialysis when S. creatinine reach 10.7 mg/l

• The syndrome has been variously called The syndrome has been variously called recurrent jaundice of pregnancy, cholestatic recurrent jaundice of pregnancy, cholestatic jaundice of pregnancy,jaundice of pregnancy,ictrus gravidarum,ictrus gravidarum, jaundice of late pregnancy, and hepatosis of jaundice of late pregnancy, and hepatosis of pregnancy. ICP, however, is the preferred term, pregnancy.

• The frequency of ICP is clearly higher The frequency of ICP is clearly higher among certain ethnic groups, including among certain ethnic groups, including Scandinavians and Chileans. In the latter Scandinavians and Chileans. In the latter group, ICP may appear in 2.4% or more of group, ICP may appear in 2.4% or more of pregnancies, the highest reported pregnancies, the highest reported incidence in the world. The incidence is incidence in the world. The incidence is quite high (20.9%) in twin pregnancies.quite high (20.9%) in twin pregnancies.

As a result of the pruritus, insomnia, fatigue, As a result of the pruritus, insomnia, fatigue, and even mental disturbances have been and even mental disturbances have been reported reported

Many patients report the appearance of dark Many patients report the appearance of dark urine without frank jaundice shortly after urine without frank jaundice shortly after the onset of pruritus.

Effects on the MotheEffects on the Motherr

• Although earlier reports suggested that the only Although earlier reports suggested that the only effect of ICP on the mother was related to the effect of ICP on the mother was related to the discomfort of pruritus, more recent studies have discomfort of pruritus, more recent studies have suggested more serious complications. These suggested more serious complications. These include an increased risk of postpartum include an increased risk of postpartum hemorrhage, especially in those given hemorrhage, especially in those given cholestyramine, and an increased risk for the cholestyramine, and an increased risk for the development of gallstones after pregnancy.development of gallstones after pregnancy.

(Glantz, et al., 2005)(Glantz, et al., 2005)

Effects on the FetusEffects on the Fetus• The implications of ICP for the fetus are The implications of ICP for the fetus are

considerably more ominous. An increased considerably more ominous. An increased incidence of prematurity and fetal death has been incidence of prematurity and fetal death has been reported in several studies. Fetal distress is reported in several studies. Fetal distress is reported in one third of patients, leading to reported in one third of patients, leading to ccesarean section in 30% to 60% of cases and esarean section in 30% to 60% of cases and prematurity in over 50% in some series. Stillbirths prematurity in over 50% in some series. Stillbirths are recorded in more than 9%. These outcomes are recorded in more than 9%. These outcomes are more likely if the disorder begins earlier in are more likely if the disorder begins earlier in pregnancy. Thus, ICP very clearly increases the pregnancy. Thus, ICP very clearly increases the risks to the fetus. risks to the fetus.

Improvement in both liver function test results and Improvement in both liver function test results and the symptom of pruritus has been documented in the symptom of pruritus has been documented in women with ICP treated with a standard women with ICP treated with a standard 15mg/kg/day dosage. A larger dosage, 20 to 25 15mg/kg/day dosage. A larger dosage, 20 to 25 mg/kg/day has been shown to be effective with no mg/kg/day has been shown to be effective with no adverse affects on either mother or baby.adverse affects on either mother or baby.
