ANALYSIS THE ALPHA-PROTEIN LEVEL IN HEPATITIS PATIENT AS AN AID IN ACCESSING THE DEGREE IN WHICH IT GENERATES TO HCC

CHAPTER ONE

 

 

  1. INTRODUCTION

Hepatocellular carcinoma (HCC) is the most common primary liver cancer. It accounts for 60% of all cancer world wide (Melissa 2004). The most significance cause is the presence of cirrhosis. HCC has unique geographic sex, age distribution that are likely determined by specific actiology factor. It’s distribution also varies  among ethnic group within the same country (Munoz 1989). A high incidence of hepatitis B and C may have been an important factor contributing to the development of liver disease (HCC and Cirrhosis) in south eastern Nigeria. However, a recent trend which reveals an increase in cases of liver cirrhosis and hepatitis in our environment suggest that there could be other contributory factors perculiar to our environment besides hepatitis B and C which could be possible explanation to the recent trend. In so doing, it would be necessary to look into the various predisposing/causative factors of chronic hepatitis which could lead to increased cases of liver cirrhosis and HCC in our environment. The risk of developing HCC differs depending on the cause of cirrhosis. For example, cirrhosis due to hepatitis B has a high risk of leading to HCC while the risk of HCC in people with primary biliary cirrhosis, although present is very low. All these human hepatitis viruses are RNA viruses except for hepatitis B virus, which is a DNA virus. Although these viruses can be distinguished by their molecular and antigenic properties, all types of viral hepatitis produce clinically similar illnesses. These range from asymptomatic and unapparent to fulminant and fatal acute infections common to all types, on one hand, and from subclinical persistent infections to rapidly progressive liver disease with cirrhosis and even hepatocullular carcinoma (HCC), common to the blood-borne types (HBV and HCV). Without specific virological test, it is not possible to determine which hepatitis virus is responsible for a case of hepatitis. (Kathleen park et al., 2004).

1.0    LITERATURE REVIEW:

 

1.1    EPIDEMIOLOGY OF VIRAL HEPATITIS:

 

Hepatitis A virus spreads by the fecal-oral route, principally through fecal  contamination of hands, food, or water. Many out breaks of the disease have originated from restaurants because food handlers who carried the virus failed  to wash their hands. Eating raw shellfish is a frequent source of infection since these animals concentrates the hepatitis A virus from fecally polluted seawater. (Gene Nester et al., 2004). A high percentage of hepatitis A occurs in low socioeconomic groups of people because of crowding and inadequate sanitation. Other groups at high risk of hepatitis A include attendees of day care centers and nursing homes, and homosexual men. Infants and children with hepatitis A can eliminate the virus in their feces for several months after symptoms begin, but the amount of virus in feces usually drops markedly with the appearance of jaundice. (Barker et al.,1996).

 

Hepatitis B, from 1965 to 1985, a progressive rise in reported hepatitis B cases occurred (William; 2006). Since then, the incidence of the disease has appeared to plateau and decline. HBV is spread mainly by blood, blood products, and semen. Persisting viremia, meaning virus circulating in the bloodstream, can follow both symptomatic and asymptomatic cases, and the virus may continue to circulate in the blood for many years. (Chang; 2007). Carriers are of major importance in the spread of   hepatitis B because they are often unaware of their infection. If only a minute amount of blood from an infected person is infected into the bloodstream or rubbed into minor wounds, infection can results. Blood and other body fluids can be infectious by mouth, the virus probably infecting the recipient through small  scratches or abrasion.

 

Many hepatitis B virus infections result from sharing of needles by drug abusers. Unsterile tattooing and ear-piercing instruments and shared toothbrushes, razors, or towels can also transmit HBV infections. (Majorie et al., 2001)

 

Sexual intercourse is responsible for transmission in nearly half of hepatitis B cases in the united states. (William;  2006). HBV antigen is often present in saliva and breast milk, but the quantity of infectious virus and risk of transmission is low.

 

Five percent or more of pregnant women who are HBV carriers  transmit the disease to their babies at delivery, and more than  two-thirds of women who develop hepatitis late in pregnancy or soon after delivery do so. Most of these babies have asymptomatic infections and become long-term carriers, but some die of liver failure (Gene Nester et al., 2004).

 

Hepatitis C although transmitted by blood from an infected person, the mechanism of exposure is not always obvious. Sharing tooth brushes, razors, and towels can be responsible. Tattoos and body piercing with unclean instruments have transmitted the disease. Approximately 60% of  transmission in the united states  are due to sharing of syringes by illegal drug abusers (Mayorie et al., 2001). Transmission by sexual intercourse is probably rare, although it apparently can occur among those with multiple partners an sexually transmitted diseases. The risk of contracting the disease from transfussion of a unit of blood is now only about 0.001%. (Gene Nester et al., 2004). The table that shows the transmission and causative agent of viral hepatitis is shown below:

The able above showed the causative agent of each viral hepatitis and their mode of transmission. From the table also it was shown that hepatitis C has no vaccines, therefore, it can be prevented by screening of blood donors.

 

1.2    FORMS OF HEPATITIS – A,B AND C VIRUS INFECTIONS

 

1.2.1 ACUTE HEPATITIS A VIRUS INFECTION

 

Hepatitis A has only one form which is acute hepatitis A infection. Acute hepatitis A infection is a self-limiting disease with an incubation period of 2- 6weeks. The onset is abrupt with fever, malaise, anorexia, nausea and lethargy which comprise the podromal (Preicteric) stage. (Arora et al., 2008). Hepatomegaly, due to cell necrosis, causes blockage of the biliary excretion resulting in jaundice (Goldstein et al., 1998). It may also produce pain in the right upper abdominal quadrant. The fulminant form of hepatitis A and liver failure can occur in less then 0.5% cases. Complete recovery occurs in 8-12 weeks. Hepatitis A has no apparent adverse effect on the outcome of pregnancy. (Prescott et al., 2008).

 

Transmission during birth by exposure to maternal faeces or by breast-feeding has been reported.

 

1.2.2 ACUTE AND CHRONIC AS A FORMS OF HEPATITIS B VIRUS INFECTION

 

ACUTE HBV INFECTION:

 

This is subclinical in 70% of adults. For newly infected persons who develop acute hepatitis, the average incubation period after infection last one to four months. Symptoms of acute HBV infection  include;

 

Nausea, anorexia, fatigue, low-grade fever,  and right upper quadrant or epigastric pain. Also, changes in stool colour, hepatomegaly or splenomegaly  may ensure (Goldstein et al., 1998). Symptoms of acute disease resolve by one to three months, although some persons have prolonged fatigue treatment of acute infection is generally supportive, although some patients require hospitalization for intravenous fluid administration (seff et al.,  1987).

 

Acute HBV infection leads to fulminant hepatic failure from massive hepato cellular necrosis in about 1 percent (1%) infection. Rarely, patient with an “exuberant” immune response present with clinical symptoms but progress hepatic decomposition, including  encephalopathy and coagulopathy. Mortality is high, and live transplantation often is necessary (Befeler et al., 2000). In person who recover from HBV infection, HBsAg is eliminated from the blood and antibody to HBsAg (anti-HBs) develops during convalescence. The presence of  immunity to HBV infection, most person who recover from natural infection (resolved infection) will be positive for both anti-HBs and anti-HBc. Acute hepatitis B infection can be managed by eating high caloric diet, having a good best rest and taking vitamins.
