GENERAL INTRODUCTION:

- ALD is defined as “LIVER DAMAGE, caused by OVER CONSUMPTION OF

ALCOHOL, leading to FAT ACCUMULATION, LIVER SCARRING, and other

complications. . .”

- ALD mainly comprises :

1. ALCOHOLIC HEPATITIS(just defined in this ppt, refer other suitable areas for

more details on the same)

2. ALCOHOLIC LIVER CIRRHOSIS(Explained more here)

3. ALCOLOHIC STEATOSIS(Summarized version)

-NOTE: It is always advisable for readers to refer sites, books, journals and other

resources for better knowledge and information nourishment. . .

DEFINITIONS:

1. ALCOHOLIC CIRRHOSIS:

“DIFFUSE PROCESS, characterized by FIBROSIS, and CONVERSION of

NORMAL HEPATIC ARCHITECTURE into STRUCTURALLY ABNORMAL

NODULES, owing to excess alcohol consumption. . .”

2. ALCOHOLIC STEATOSIS(FATTY LIVER):

“Condition, associated with ACCUMULATION of FAT DROPLETS inside LIVER

CELLS, owing to excess alcohol intake. . .”

3. ALCOHOLIC HEPATITIS:

“Condition, associated with INFLAMMATION of LIVER, owing to excess alcohol

intake. . .”

GENERAL EPIDEMIOLOGY:

1. ALD is the 3rd leading cause of death in the US

2. Worldwide prevalence is estimated to be around 1.7%

3. Worldwide mortality rate is approximately 1,50,000 deaths/ year. . .

ETIOLOGY/ CAUSES:

1. AGE:

- High rates of morbidity observed between 45-64 years of age

2. GENDER:

- Prevalence is higher in men

- Susceptibility risk is higher in women

3. ETHNICITY:

- CIRRHOSIS related deaths are found to be high in HISPANICS

- SOUTH ASIAN MEN are more susceptible to alcohol related injury, than

EUROPEANS

4. HCV INFECTION:

- 14-36% of patients, with ALD, have HEPATITIS ‘C’ infection too

- HCV + ALD combination increases risk for HEPATOCELLULAR

CARCINOMA(HCC) reduces response to INTERFERON-ALPHA therapy

5. HBV INFECTION:

- HBV + ALD combination increased risk of HCC

6. IRON OVERLOAD:

- IRON + Alcohol combination generation of REACTIVE OXYGEN SPECIES

Causes LIPID PEROXIDATION Leads to cell injury causes FIBROSIS,

HCC, and increased risk of mortality. . .

7. MEDICATIONS:

Include:

i. ISONIAZID

ii. ACETAMINOPHEN

iii. NITROFURANTOIN

8. DIET & LIFESTYLE FACTORS:

Include:

i. Obesity

ii. Pork products. . .

PATHOPHYSIOLOGY OF CIRRHOSIS:

- Cirrhosis leads to PORTAL HHYPERTENSION(HTN), due to FIBROTIC

CHANGES within HEPATIC SINUSOIDS, abnormal levels of VASODILATOR &

CONSTRICTOR MEDIATORS, etc.

- CIRRHOSIS leads to 4 major COMPLICATIONS:

1. ASCITES

2. PORTAL HTN & ESOPHAGEAL VARICES

3. HEPATIC ENCEPHALOPATHY(HE)

4. COAGULATION/ BLEEDING DISORDERS. . .

1. ASCITES:

- Refers to “PATHOLOGIC ACCUMULATION of LYMPH FLUID within

PERITONEAL CAVITY”

- Occurs, due to:

a. Activation of RAAS(Renin-Angiotensin-Aldosterone-System)

b. SODIUM & WATER retention. . .

2. PORTAL HTN & ESOPHAGEAL VARICES:

- Due to PORTAL HTN VARICES(alternative routes of blood flow, from portal to

systemic circulation, bypassing liver) form leads to HEMORRHAGE Causes

death. ..

3. HEPATIC ENCEPHALOPATHY(HE):

- Refers to “CNS DISTURBANCE, associated with wide range of

NEUROPSYCHIATRIC SYMPTOMS, due to HEPATIC INSUFFICIENCY, and

LIVER FAILURE(LF)”

- Caused by BUILD-UP of NITROGENOUS substances in circulation

- Accumulation of nitrogenous substances in circulation substances enter CNS

alter neurotransmitters, that affect consciousness and behaviour

- HE is of 3 types:

a. TYPE A: Occurs due to ACUTE LIVER FAILURE(ALF)

b. TYPE B: Occurs due to VARICES

c. TYPE C: Occurs due to CIRRHOSIS. . .

4. BLEEDING/ COAGULATION DISORDERS:

- Include:

a. Reduced synthesis of coagulation factors

b. Increased fibrinolysis

c. Thrombocytopenia

d. DIC(Disseminated Intravascular Coagulation). . .

CLINICAL MANIFESTATIONS :

1. Hepatomegaly(Liver enlargement)

2. Spleenomegaly(Spleen enlargement)

3. Pruritus

4. Palmar erythema(Reddening of the palms, and occasionally, fingers)

5. Spider angiomata:

- “Form of TELANGIECTASIS(swollen blood vessels), found slightly below the

skin surface, often containing a central red spot, and reddish extensions, that

radiate outwards like a spider’s web”

- Also known as NEVUS ARANEUS, SPIDER NEVUS, VASCULAR SPIDER and

SPIDER TELANGIECTASIS

6. Ascites

7. Pleural effusion

8. HE

9. Gynecomastia

10. Reduced libido. . .

DIAGNOSIS:

1. Hypoalbuminemia

2. Raised PT

3. Raised ALP

4. Raised AST

5. Raised ALT

6. Raised GGT. . .

MANAGEMENT OF CIRRHOSIS:

INCLUDES:

1. GOALS OF THERAPY

2. TREATMENT OF PORTAL HTN AND VARICES

3. TREATMENT OF ASCITES

4. SBP

5. TREATMENT FOR HE

6. NON-PHARMACOTHERAPY. . .

1. GOALS OF THERAPY:

a. Resolution of complications like VARICEAL BLEEDING, HE, etc

b. Prevention of complications

c. To encourage ALCOHOL ABSTINENCE

d. To reduce PORTAL BLOOD PRESSURE(PORTAL HTN)

e. To avoid morbidity and mortality

f. To improve HRQoL. . .

2. TREATMENT OF PORTAL HTN & VARICES:

- Treatment strategies include:

a. PROPHYLAXIS, TO PREVENT PRIMARY BLEEDING

b. TREATMENT OF ACUTE VARICEAL HEMORRHAGE

c. PROPHYLAXIS, TO PREVENT SECONDARY BLEEDING

A. PROPHYLAXIS, TO PREVENT PRIMARY BLEEDING:

- Usually, NON-SELECTIVE BETA-BLOCKERS are used

- Drugs reduce PORTAL HTN, by:

i. Reducing C.O

ii. Reducing splanchic blood flow

- Usually, they need to be used for life(to prevent recurrence)

- Prevent bleeding

- Drugs used, include:

i. PROPRANOLOL( 10 mg TID)

ii. NADOLOL (20 mg OD)

B. TREATMENT FOR ACUTE VARICEAL HEMORRHAGE:

The following methods can be used:

1. Resuscitation

2. ABC(Maintain “A”irways, “B”reathing, and “C”irculation)

3. Sedation, as necessary

4. Somatostatin

5. Octreotide

6. Prophylactic antibiotics therapy

7. Beta-blockers

8. Surgical shunt

9. Balloon tamponade

10. Sclerotherapy

11. Terlipressin. . .

NOTE: An algorithm is provided in DIPIRO text, regarding management of

variceal hemorrhage. Go through the same, for a detailed understanding of this

sub-division.

- VASOACTIVE DRUG THERAPY:

a. Reduce splanchic blood flow

b. Reduce portal pressure

c. Drugs used, include:

i. Somatostatin

ii. Octreotide(i.v bolus, 50-100 mcg)

iii. Terlipressin. . .

- ANTIBIOTIC THERAPY is used to prevent SEPSIS in patients, with ASCITES

- EBL(Endoscopic Band Ligation) is also preferred for acute variceal bleeding)

C. PROPHYLAXIS, TO PREVENT SECONDARY

BLEEDING:

- Usually (BETA-BLOCKERS + EBL) combination is preferred to reduce

HEPATIC VENOUS PRESSURE

- Drugs used include:

1. NADOLOL: 20-40 mg OD

2. PROPRANOLOL: 20 mg TID

- If beta-blocker alone is not effective use the same in combination with

ISOSORBIDE DINITRATE, to reduce portal pressure. . .

3. TREATMENT OF ASCITES:

- Alcohol abstinence

- Sodium restriction(2 g/day)

- DIURETICS:

i. Renal insufficiency

ii. Encephalopathy

iii. Hyponatremia

- Weight loss consideration

- For tense ascites opt for PARACENTESIS(4-6L) before going for diuretics/

sodium restriction

- For REFRACTORY ASCITES LIVER TRANSPLANTATION is the only option

left. . .

4. SBP:

So consult with your dietician or physician regarding consumption of the same. . .

PATHOPHYSIOLOGY OF ALCOHOLIC STEATOSIS:

• Increased ALCOHOL INTAKE Stimulates ADRENAL PITUITARY AXIS

Increases LIPOLYSIS

• CHRONIC ALCOHOL INTAKE leads to 2 consequences:

a. Inhibition of FATTY ACID OXIDATION in liver

b. Release of VLDL into blood

• Above consequences, tantamount in the end, to STEATOSIS. . .

MANAGEMENT OF ALCOHOLIC STEATOSIS:

• Alcohol abstinence

• Consume foods rich in Vitamin ‘C’ & ‘E’

• Focus on a LOW FAT DIET

• Correct OBESITY

• Avoid high FRUCTOSE DIETS(Sodas, preserved foods, etc). . .

5. TURMERIC:

- Contains CURCUMIN powerful antioxidant

6. PAPAYA

7. GREEN TEA:

- According to a 2013 study in “INTERNATIONAL JOURNAL OF MOLECULAR

MEDICINE” Green tea is highly effective in liver detoxification. . .

PATIENT COUNSELLING TIPS FOR STEATOSIS:

1. Avoid fructose diets

2. Avoid white flour

3. Consume FISH OILS

4. Consume FLAX SEEDS
