Diagnostic Features and Clinical Presentation
Diagnosis is often complicated by the fact that patients tend to conceal their alcohol use. For this reason, objective somatic and neurological manifestations, as well as formal psychiatric evaluation, are critical for confirming the etiology.
Early stages of the disease may be completely asymptomatic. However, initial physical examination frequently reveals hepatomegaly, which can reach significant dimensions. As the condition progresses, portal hypertension syndrome comes to the forefront.
Specifics of Portal Hypertension
The clinical course of portal hypertension in alcoholic liver disease has distinct differences compared to viral cirrhosis:
- Ascites forms much earlier. In 77% of patients, fluid accumulation in the abdominal cavity is already detected at the time of diagnosis. The onset of ascites is frequently the primary reason for seeking medical attention.
- Splenomegaly (enlargement of the spleen), by contrast, develops much later. In some patients, splenic size remains within normal limits even in advanced stages of the pathological process.
Extrahepatic Stigmata and Systemic Disturbances
Due to chronic systemic intoxication, extrahepatic manifestations develop earlier than in viral liver disease.
General disturbances include marked dystrophic changes, severe weight loss, and signs of profound hypovitaminosis. Digestion is impaired, presenting as exocrine pancreatic insufficiency and malabsorption syndrome (impaired intestinal absorption).
Specific "alcoholic" stigmata include:
- Neuromuscular lesions: polyneuropathy, myopathy, muscular atrophy.
- Connective tissue changes: Dupuytren's contracture.
- Glandular disorders: enlargement of the parotid salivary glands (parotitis).
- Endocrine and trophic failures: alopecia, testicular atrophy.
Laboratory Profile and Types of Anemia
Liver function tests in this condition are often only mildly altered. Protein metabolism shows hypoproteinemia and moderate hypergammaglobulinemia. Enzyme activities (ALT, AST) are elevated no more than 3–4 times above normal. The immunological profile typically features elevated IgA levels.
Anemia is a very common finding, and its etiology is highly diverse:
- Posthemorrhagic — resulting from blood loss via erosive gastritis or hemorrhoids.
- Hypoplastic — caused by the direct toxic effect of ethanol on bone marrow hematopoiesis.
- Megaloblastic — associated with dietary folate deficiency, as well as impaired folate metabolism and absorption.
- Sideroachrestic — developing due to vitamin B6 (pyridoxine) metabolism disturbances, leading to impaired heme synthesis.
- Hemolytic — resulting from increased erythrocyte destruction.
Terminal Stage and Prognosis
The clinical picture of the terminal stage is characterized by extreme wasting (cachexia), severe liver failure with prominent jaundice, fever, and hemorrhagic diathesis. At this stage, ascites becomes persistent and refractory (poorly responsive to medical therapy).
Key fatal complications include:
- Esophageal variceal bleeding (EVB), frequently leading to hepatic coma.
- Hepatorenal syndrome.
- Secondary infections (peritonitis, pneumonia).
- Prognosis can be relatively favorable only with total abstinence from alcohol, adequate nutrition, and vitamin supplementation. Patients who stop drinking show significantly higher survival rates.
