extracellular
matrix in liver
synthesis
of matrix
proteins
degradation
of matrix
proteins
Collagens type I and III
constitute more than
95% of the total content
of increased collagen in
fibrotic liver
Pathogenesis,chronic,progressed,
diffuse
? Hepatocyte injury leading to necrosis,
? Chronic inflammation - (hepatitis),
? Capillarization (肝窦毛细血管化 ) of the space of
Disse is a key event,
? Bridging fibrosis,
? Regeneration of remaining hepatocytes
proliferate as round nodules surrounded by
fibrous septa,
? Loss of vascular arrangement results in
regenerating hepatocytes ineffective,
? Cirrhosis may lead to liver failure,portal
hypertension,or development of hepatocellular
carcinoma
Histopathologic classification
? micronodular
uniformly small nodules (< 3 mm in diameter) and
regular bands of connective tissue
? macronodular
nodules that vary in size (3 mm to 5 cm in diameter)
? mixed macro and micronodular
(incomplete septal cirrhosis) combines elements
of micronodular and macronodular cirrhosis,
Consequences of portal hypertension[I]
1.Splenomegaly (脾肿大 )
2.Formation and open of portal-
systemic collateral’s (门体侧支循环
开放 )

(short gastric/coronary veins)
--Rectal collateral‘s(痔静脉丛 )
(Suphemorrhoidal/middle & inf,hemorrhoidal)

?Hepatopulmonary syndrome
(HPS,肝肺综合征 )
HRS is characterized clinically by the triad of
pulmonary vascular dilatation causing arterial
hypoxemia in the setting of advanced liver
disease,
HRS(Hepatorenal syndrome,肝肾综合征 )
? Occurred in the setting of,
---chronic liver disease
---advanced hepatic failure
---portal hypertension
? characterized by,
---impaired renal function
---marked abnormalities in arterial circulation
---activation of endogenous vasoactive system
? Classified into 2 different types,
---Type I,Rapidly progressive
---Type II,Not rapidly progressive,Often results in
mild renal insufficiency causing diuretic resistant ascites
Mechanisms of HRS[II]
Clinical features[I]
Compensated cirrhosis (代偿期 )
Many people experience few symptoms at the onset of
cirrhosis,symptoms are typically vague and nonspecific,
---Fatigue and loss of energy,
---Loss of appetite and nausea,
---Spider angiomas
---liver function is normal
Decompensated cirrhosis (失代偿 )
? Symptoms caused by loss of functioning
liver cells
--- System,fatigue,weakness,weight loss,malnutrition
--- Digestive System:Loss of appetite,nausea,diarrhea,
Clinical features[II]
---Tendency to hemorrhage(出血倾向 ) and
anaemia(贫血 ),Due to reduced synthesis of
coagulation factors (II,V,VII,IX,X),
hypersplenism(脾亢 ),low platelet count,poor
absorption,gastrointestinal bleeding,
---Hormonal abnormalities
gynecomastia(男性乳房发育 ),telangiectases
(毛细血管扩张症 ),spider nevi(蜘蛛痣 ),palmar
erythema(肝掌 )
---Jaundice(黄疸 )

or renal dysfunction,abdominal pain (occurring
only in 50% of patients),and encephalopathy
are the most common clinical findings in SBP,
However,the patient is frequently
asymptomatic,Because culture of ascites fluid
is negative in a large number of patients with
SBP,diagnosis should be based on the presence
of >250 neutrophils/mm3,

Diagnosis [I]
? Etiology of cirrhosis
? Pathology of cirrhosis
? Evaluating of liver function,Child-Pugh
classification
? Searching for complications
Diagnosis[II]
? the history of disease contributes to identifying the cause
of cirrhosis,
history of viral hepatitis,blood transfusions,medication
use,alcohol use,sexual practices should be carefully
reviewed,
? signs and symptoms confirm to existence of portal
hypertension and impared liver function,
? liver function tests,hypoalbuminemia,hyperbilirubinemia,
the prolonged prothrombin time suggest hepatic
decompensation,
? Imaging study,Ultrasound and CT readily identify the
lesion,but have no characteristic findings,

Treatment of SBP
1,Ascites PMN>250/mm3, antibiotic therapy should be
initiated,
2,Ascites PMN<250/mm3 and ascitic fluid culture
continues to be positive,initiation of antibiotic treatment,
3,Follow-up diagnostic paracentesis performed 48 hours
after starting therapy allows assessment of response to
treatment and the need to modify antibiotic coverage,
4,Long-term prophylaxis ---Patients who have recovered
from an episode of SBP are at a high risk of developing
SBP recurrence,
Therapies for HRS[I]
? Avoid use of nephrotoxic drugs,
( 1) Antibiotics, aminoglycosides
( 2) NSAIDs,inhibit formation intrarenal
prostaglandins
---marked decline in renal function
? Avoid and treat factors to hypovolaemia,
( 1) active treatments of upper gastrointestinal
bleeding
( 2) Judicious use of diuretics( weight loss<0.5Kg/d)
? Rectify electrolyte and metabolic
imbalance,Fluid intake restriction
Therapies for HRS[II]
? Volume expansion,with IV dextrose,plasma,albumin
or Concomitant plasma volume expansion with
albumin has been used with LVP to correct decreased
effective arterial volume that leads to sodium retention,
TIPS
? Vasoactive drugs,terlipressin(可利新 ),
ornipressin,dopamine,---increasing renal plasma flow
? Elimination of endotoxaemia and control
infections
? Liver transplantation,the most effective
treatment for patients with HRS
