Hepatitis simply means inflammation of the liver. When liver cells become injured or infected, they swell and lose their ability to filter blood, process nutrients, and fight off infections. While heavy alcohol use, toxic drugs, and autoimmune conditions can trigger this damage, viral infections remain the most common cause globally, particularly in resource-limited settings across Nigeria.
Understanding the basic pathology helps midwives explain to pregnant women why routine screening matters. The liver is remarkably resilient, but prolonged inflammation leads to scar tissue formation, known as fibrosis. If left unchecked, this scarring progresses to cirrhosis, permanently altering liver architecture and severely reducing blood flow through the organ. Recognizing early signs prevents this long-term deterioration.
Viral hepatitis is caused by several distinct viruses, each behaving differently inside the human body. Clinicians group them alphabetically, though Hepatitis A, B, C, D, and E are the primary strains of public health concern.
Many individuals with viral hepatitis experience mild, flu-like symptoms or no symptoms at all during the early stages, making silent transmission common. When symptoms do appear, they typically progress through distinct phases.
During the prodromal phase, patients complain of fatigue, low-grade fever, nausea, and right upper quadrant abdominal discomfort. As the condition advances into the icteric phase, jaundice develops, turning the sclera and skin yellow due to elevated bilirubin levels. Urine darkens significantly like strong tea, and stools become pale or clay-colored because bile fails to reach the intestine. The convalescent phase marks the gradual fading of jaundice and return of appetite, though fatigue may linger for months.
Confirming a hepatitis diagnosis requires a combination of blood tests and clinical evaluation. Liver function tests (LFTs) measure specific enzymes that leak into the bloodstream when liver cells are damaged. Elevated levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) signal active cellular injury.
Beyond general enzyme panels, specific serological markers identify the exact virus responsible. For instance, detecting Hepatitis B surface antigen (HBsAg) confirms an active infection. Midwives must understand these lab results to interpret antenatal screening panels correctly and refer clients needing specialized care promptly.
Care for a patient with viral hepatitis focuses on resting the liver, managing symptoms, and preventing further complications. Most acute cases require supportive care at home, emphasizing adequate hydration, nutritious small meals, and complete avoidance of alcohol and hepatotoxic drugs like paracetamol.
For chronic Hepatitis B and C, antiviral medications can suppress viral replication and reduce liver damage over time. Midwives caring for hospitalized patients must maintain strict universal precautions, safely handling sharps and contaminated linens to prevent nosocomial spread.
Public health measures remain the most effective tool against the burden of viral hepatitis. Routine childhood immunization programs include the Hepatitis B vaccine, which is safely administered within the first 24 hours of life alongside the birth dose of the polio vaccine.
Community health education focuses on safe water supply, proper sewage disposal, and practicing safe sex. Midwives play a frontline role by screening pregnant women during antenatal visits and administering Hepatitis B immune globulin (HBIG) alongside the vaccine to newborns of positive mothers, effectively blocking vertical transmission.
