Hepatitis: WHO, Experts Call For More Awareness
As the world marks Hepatitis Day tomorrow, MOTUNRAYO JOEL writes that experts seek more awareness campaigns about the deadly disease
Hepatitis which is the inflammation of
the liver has been proven by experts to be one of the deadliest diseases
on earth. Many experts have even described it as deadlier than the
dreaded Human Immunodeficiency Virus.
A consultant/physician, gastroenterologist, Dr. Sylvester Nwokediuko, who spoke with SUNDAY PUNCH, linked this opinion to the fact that the virus that causes Hepatitis B is 100 times more infectious than HIV.
“Some of the reasons why hepatitis is
deadlier than HIV are because the virus that causes hepatitis B is 100
times more infectious than HIV. Secondly, in terms of the magnitude of
the problem, that is hepatitis, many more people have hepatitis B. it
has been estimated that 20 million Nigerians have hepatitis. Thirdly,
based on its natural history, hepatitis B can cause more destruction of
the liver leading to liver cirrhosis and cancer. These two conditions
are not easy to treat, a patient with cirrhosis would need to undergo
liver transplant. Unlike hepatitis, HIV affects the immune system, and
there are people who have a strong immune system. Hence, it is possible
for them to carry on living their normal lives even with the virus in
their system. Hepatitis generally causes more morbidity.”
Meanwhile, the World Health Organisation
in its 2014 fact sheets estimates that two billion people have been
infected with the hepatitis B virus worldwide. It, however, puts the
figure of those chronically infected with hepatitis C at 170 million.
Reacting to the statistics, Nwokediuko
acknowledged the figures disclosing that 400 million out of the two
billion, have chronic infections that require evaluation and treatment,
He continued, “Between 600,000 to one
million people worldwide will die of hepatitis B complicated related
illnesses yearly. However, in Nigeria, because we have a poor
record-keeping skill, it’s difficult to put a figure to the number of
Nigerians that will die annually, but close to 10 per cent of deaths in
teaching hospitals and the medical centres are as a result of chronic
liver diseases. Hepatitis is one of the infections that cause liver
disease.”
The President, Society for
Gastroenterology and Hepatology, Nigeria, Prof. Olusegun Ojo, explained
that inflammation of the liver could also be caused by a viral
infection.
He said, “A range of viruses can infect
the liver but a peculiar group have predilection for the liver,
selectively infecting it whenever they get into the human body. These
viruses are referred to as the hepatotropic viruses and they are denoted
by alphabets A to E in literature.
“Although, certain non-hepatotropic
viruses such as the yellow fever virus are capable of infecting the
liver alongside other organs, they are not considered to be agents of
viral hepatitis because they do not cause liver-specific disorders. In
particular, types B and C lead to chronic disease in hundreds of
millions of people and, together, are the most common cause of liver
cirrhosis and cancer.”
He continued: “Hepatitis A and E are
typically caused by ingestion of contaminated food or water. Hepatitis
B, C and D usually occur as a result of parenteral contact with infected
body fluids. Common modes of transmission for these viruses include
receipt of contaminated blood or blood products, invasive medical
procedures using contaminated equipment and for hepatitis B transmission
from mother to baby at birth, from family member to child, and also by
sexual contact.
“Acute infection may occur with limited
or no symptoms, or may include symptoms such as jaundice (yellowing of
the skin and eyes), dark urine, extreme fatigue, nausea, vomiting and
abdominal pain.”
However, according to Nwokeduiko, any
infection that lasts for more than six months becomes chronic and
chronic hepatitis may lead to liver cirrhosis and liver cancer if
untreated.
“It’s these complications that may shorten one’s life,” he warned.
With the serious nature of this disease
in its various forms, it is sad that the level of awareness on its
existence and causative factors are, according to Ojo, low in Nigeria.
“There is a dearth of information on
hepatitis in Nigeria. There needs to be increased efforts at educating
communities on prevention of spread among children (through harmful acts
of native surgeries such as tribal markings, genital mutilations and so
on). Vaccination is not extended to schoolchildren but new born through
the pentavalent which shouldn’t be so.”
He called on the Federal Government to put more effort in generating measures that would educate people about the infection.
“The Federal Government needs to increase
the knowledge of hepatitis B among the general public. Educating the
general public regarding hepatitis B, including how it is transmitted,
prevented and treated, will result in more people reducing or
eliminating their risk of infection. It would also improve their chances
of getting screened, diagnosed and vaccinated, whatever the applicable
scenario in the individual case. By raising awareness about the disease,
the burden will reduce in the population over time.
“At the same time, Nigerians should take
steps to determine their HBV and HCV statuses by getting screened in
hospitals and medical laboratories. If negative, they should seek to be
vaccinated and, if positive, they should ask to see hepatologists,
specialist physicians who are knowledgeable and conversant with further
testing and treatment.”
Ojo also highlighted various treatment options available for the deadly disease.
“On the treatment of hepatitis B and C,
antiviral agents active against HBV exist. However, drugs active against
HBV are not widely available or utilised in persons infected with HBV.
HCV on the other hand is generally considered to be a curable disease
but for many persons this is not a reality.”
An online site, www.dnaindia.com,
claims scientists have revealed that a combination drug therapy cures
chronic hepatitis C in the majority of patients co-infected with both
HIV and hepatitis C.
However, the WHO is not treating the
disease with kid gloves as it has called for intensified campaign
against it. The theme for this year’s World Hepatitis Day is, ‘Think
Again.’
In a statement, WHO called for an
increase in awareness and understanding of viral hepatitis, its
symptoms, treatment and prevention.
