B16.2
Acute hepatitis B without delta-agent with hepatic coma
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 Code B16.2 refers to a specific type of hepatitis B infection characterized by acute illness without the presence of the delta-agent, also known as hepatitis D virus, and complicated by hepatic coma. Hepatitis B is a viral infection that primarily affects the liver, leading to inflammation that can be temporary or long-lasting. The designation B16.2 indicates that the infection is in an early, acute stage but has progressed to a severe complication involving impaired consciousness due to liver failure. Recognizing this condition is vital for understanding its severity and potential impact on health.
Causes & Symptoms
Clinical Causes: Transmission of hepatitis B virus through contact with infected blood or bodily fluids Unprotected sexual contact with an infected individual Sharing contaminated needles or syringes Mother-to-child transmission during childbirth Transmission through transfusion of infected blood products (though rare in many countries due to screening)
Key Symptoms: Jaundice (yellowing of the skin and eyes) Fatigue and weakness Loss of appetite Nausea and vomiting Abdominal pain or discomfort Dark urine and pale stools Fever Swelling in the abdomen Hepatic coma, which involves altered consciousness, confusion, and a decreased response to stimuli In advanced cases, seizures or coma may develop as a result of hepatic failure
Diagnostic & Treatment
Diagnosis Path: Serologic tests detecting hepatitis B surface antigen (HBsAg), indicating active infection Tests for hepatitis B e-antigen (HBeAg) to assess infectivity Liver function tests to evaluate liver damage Blood tests for hepatic coma markers, such as serum ammonia levels Imaging studies like ultrasound or CT scans to assess liver condition Neurological assessments to determine the extent of hepatic coma
Treatment Protocols: Hospitalization for close monitoring of liver function and neurological status Supportive care to maintain hydration, electrolyte balance, and proper nutrition Management of hepatic coma with measures to reduce intracranial pressure and support vital functions Use of antiviral medications, if indicated, to limit viral replication Treating any underlying cause or complications, such as infections or bleeding In some cases, liver support therapies or transplantation may be necessary if liver failure progresses
