ABSTRACT
A total of 50 blood (30 pregnant and 20 HIV) samples
were obtained from pregnant women and PLWHA attending clinic at UNTH
Ituku-ozalla. Samples were screened for hepatitis c viral infection using the
rapid one step hepatitis C virus test strip. Two (6.66%) pregnant women were
positive and four (20%) HIV patients were positive for Hepatitis C, giving an
overall prevalence rate of (26.7%). The infection was the same in male (3) and
in female (3). Those aged 23-34 years recorded a higher prevalence of (20%)
than those in the age group 19-23. This higher prevalence of hepatitis C
suggests that pregnant women and PLWHA may be at risk of hepatitis due to
hepatitis C virus. Therefore routine screening of pregnant women and PLWHA
should be instituted for early diagnosis and management of cases.
CHAPTER

1.1 INTRODUCTION
Hepatitis C infection is an infection of the liver
caused by the hepatitis C virus (HCV). HCV is one of several viruses that can
cause hepatitis. 'Hepatitis' means inflammation of the liver (Ryan and Ray,2004).It
is unrelated to the other common hepatitis viruses (for example, hepatitis A or
hepatitis B). HCV is a member of thehepacivirus genus in the familyFlaviviridae.
There are at least six distinctly different strains of the virus which have
different genetic profiles (genotypes). In the U. S., genotype 1 is the most
common form of HCV. Even within a single genotype there may be some variations
(genotype 1a and 1b, for example). Genotyping is important to guide treatment
because some viral genotype respond better to therapy than others (Wilkins et
al. 2009).
According to Hepatitis C NSW (2010), here are some
of the things that can happen once the body contract hepatitis C.
The body may deal with hepatitis C of its own accord
and you may never get sick.About 25% of all people who contract hepatitis C
will clear the infection (although this happen less commonly in people with
HIV). For a range of reasons, hepatitis C infection is eradicated from the body
in these people, usually within 12 months of having been infected. Hepatitis C may remain present in the body. About
three quarters of people who contract hepatitis C will be chronically infected.
This means that they have detectable hepatitis C virus (measured by a PCR test)
in their blood for a period of longer than twelve months. People in this group
may be at risk of developing liver problems over time. The genetic diversity of HCV is one reason that it has
been difficult to develop an effective vaccine since the vaccine must protect
against all genotypes. It is difficult for the human immune system to eliminate
HCV from the body, and infection with HCV usually becomes chronic. Over
decades, chronic infection with HCV damages the liver and can cause liver
failure. Up to 85% of newly-infected people fail to eliminate the virus and
become chronically infected. Infection is most commonly detected among people
who are 40 to 60 years of age, reflecting the high rates of infection in the
1970s and 1980s. There are 8,000 to 10,000 deaths each year in the U.S. related
to HCV infection. HCV infection is the leading cause of liver transplantation
in the U.S and is a risk factor for liver cancer.
Most of the signs and symptoms of HCV infection
relate to the liver. Less commonly, HCV infection causes conditions outside of
the liver. Symptoms are generally mild and vague, including a decreased
appetite, fatigue, nausea, fever. Headache, muscle or joint pains, and weigh loss.Hepatitis
C after many years becomes the primary cause of cirrhosis and liver
cancer. About 10–30% of people develop cirrhosis over 30 years (Meisel, et
al. 1995). HCV infection can cause the body to produce unusual
antibodies called 'cryoglobulins'. These cryoglobulins cause inflammation of
the arteries (vasculitis) which may damage the skin, joints, and kidneys. In
addition, these patients may develop Raynaud's phenomenon in which the fingers
and toes turn color (white, then purple, then red) and become painful at cold
temperatures(Iannuzzella, and Vaglio, 2010). Two skin conditions, lichen planus and porphyria
cutaneatarda, have been associated with chronic infection with HCV. HCV also is
associated with B-cell lymphoma, a cancer of the lymph system. Doctors use various tests to determine if a person
has hepatitis C. One type of test measures antibodies in the blood, indicating
that a person been exposed to HCV; the two most common antibody tests are
called ELISA and RIBA. Viral load tests measure how much HCV genetic material
is present in the blood; the two most common viral load tests are called PCR
and bDNA.
