What is Hepatitis C?

In order to define Hepatitis C, we need to first explain the functioning of the liver. Being a liver disease makes it crucial for us to provide you with basic understanding of this organ if we want to answer your question ‘What is Hepatitis C?’.

What is Hepatitis C

Every person has a liver. This is the one of the most important, largest organs in the human body. The liver is located behind the right part of the ribs for protection and it has numerous functions such as:

  • Filtering the blood by breaking down drugs, chemicals, alcohol and removing waste. So, if you consume prescriptions, street drugs or even over-the-counter medicine, the job of this organ is to defend your body from the harmful substances.
  • Storing important nutrients like fat, sugar and vitamins from the food people are consuming. Aside from these nutrients, the liver is known to store other chemical and help the spreading of such chemicals in the bloodstream when needed.
  • Producing chemicals aside from storing them. Such chemicals are necessary for the human blood to clot and heal when an injury occurs. Additionally, the live produces a bile, which assists the fat digestion in the body.

Now that we have established the liver function, it is time to define Hepatitis C. Hepatitis C is an inflammation of the liver. When the liver is swollen or inflamed, this may reduce its ability to perform its function.

Aside from hepatitis c, the liver can be inflamed by too much alcohol intake, medications and other diseases.

With the advancement in medicine, people with chronic HCV or hepatitis C virus have better outlook. With the introduction of the new anti-viral drugs, HCV is now curable for the majority of people diagnosed with this disease. Such drugs are often prescribed in combination with other drugs, but may also be prescribed to be used alone.

Hepatitis C attacks the liver by causing an infection. When this disease becomes chronic in patients, the liver becomes sick and may result in cirrhosis, cancer and complete failure.

People are often scared that they would get hepatitis C because this virus is easily transmitted. You can get HCV trough bodily fluids, including blood. This is why at a certain point in the past, blood transfusions were the main reason for spreading this disease. Today, people who are current drug users are at high risk of developing hepatitis C, since this disease is transferred trough the needles they share. Also, the people who had received a blood transfusion for some reason before the year of 1992 are at risk too.

The scary thing with this disease is that it does not show symptoms until the disease has progressed in the body of the patient. Only 15 to 20 percent of all people who have this virus fight it off without any treatment.

History of Hepatitis C

  • Epidemic and Campaign Jaundice

In the 8th century A.D the Hepatitis C virus was understood and described as something called ‘epidemic jaundice’. The Pope Zacharias has quaranteened people and animals that had this jaundice in order to prevent the disease from spreading to others.

During the Civil War, there were more than 40 thousands cases of jaundice reported by the Union Army. Armies were seriously harmed by this condition, which is the reason why HCV began to be referred to as ‘campaign jaundice’.

  • HCV in World War II

During World War II, there were 182.383 service members being hospitalized for this disease. For what is known the disease was recognized in the form of serum and acute type and broke out among many of the members who had received a vaccine for yellow fever. When this happened, people started to look for the source in the serum being used to fight yellow fever, so they started calling this vaccine the serum hepatitis.

The acute type of hepatitis started developing in those soldiers that went through blood transfusions.

  • Hepatitis B discovered by accident

In the 1960s, Baruch Blumberg began researching genetic links. Such links were supposed to explain the connection to susceptibility to certain diseases. While doing this research, Blumberg accidentally found a blood sample of an Australian Aborigine that contained the hepatitis B virus. When this was discovered, a test for screening people for this virus was immediately developed, which then resulted in creating a vaccine that would fight the disease. The vaccine has proved to be effective and is used nowadays, too.

Blumberg received the Nobel Prize in 1976 for this amazing discovery.

  • The discovery of hepatitis A

After the discovery of hepatitis B, scientists led by Feinstone began identifying the hepatitis A virus in the National Institutes of Health. The first discovery of hepatitis A can be traced to prisoner volunteers’ fecal samples.

After the discovery of hepatitis A, a vaccine was developed in 1981. The microbiologist that developed this effective vaccine was Hilleman.

  • The discovery of third hepatitis type

The proteins found in hepatitis A and B were not testing positive for some cases of hepatitis. In 1975, some British and American researchers began researching and realized that there is a separate virus aside from the two known ones that is the cause of the death of people.

  • The identification of hepatitis C

Hepatitis C was finally identified as a virus in 1989. The Centers for Disease Control and Prevention joined forces with Chiron to come up with this conclusion. However, no vaccine or drug has existed for treating hepatitis C until the year of 1991.

  • Hepatitis C drug approval

After many years of research and failed attempts, the Food and Drug Administration has finally approved the first hepatitis C drug. This drug is the interferon alfa-2B, also referred to as Intron A. This is the first known interferon drug being used for the treatment of hepatitis C in patients.

To clarify, the interferons are found in the human body. We are speaking of proteins that got the name because of the replication of the hepatitis C virus.

  • Blood supply testing

Before the first drug was introduced, the United States began screening blood supply for HCV in 1990. It was 1992 when a better test was introduced.

  • Interferon and Ribavirin combination approved

Six years later, the FDA approved ribavirin to be used in combination with interferon with the purpose of treating hepatitis C. When used on its own, ribavirin showed no effect in treating this disease, but if the two were combined together or in combination with other drugs too, a better therapy was introduced. Right now, this drug is the most effective known cure for preventing HCV relapse.

  • Interferon and Polyethylene glycol effectiveness

This mixture was introduced in the year of 2001, with the aim of helping the hepatitis c drug remain in the human bloodstream for longer periods of time. This was the year when FDA approved the combination of ribavirin and pegylated interferon and the pegylated interferon on its own.

  • Ora Quick rapid antibody test approved

Nine years after the approval of the pegylated interferon, FDA approved a test that was called Oraquick. This test is a rapid antibody test, which gives results in only 20 minutes.

  • New medications approved by FDA

The year of 2013 was a very positive year for hepatitis C patients. In 2013, the FDA has approved three medications for treating HCV.

The first approved medication was Sofosbuvir or Sovaldi, used in therapies of HCV. This drug is not used in combination with the approved pegylated interferon and costs a lot. This is why many people throughout the world cannot afford to use this drug as their HCV treatment. If an individual is qualified, the SupportPath compassion program may be able to subsidize the drug.

Another approved medication was the combination of Sovaldi and ribavirin, which also works without the addition of pegylated interferon. The third approved drug is Olysio or Simeprevir, also used without the interferon.

All these drug show different ranges of effectiveness in different patients. The effectiveness also depend on the HCV genotype and the drugs used for treatment. They are all available in pill form and offer a shorter treatment length than other drugs. Additoinally, all three are now proven to result in fewer side effects when compared to other drugs.

Hepatitis can cause acute and chronic infection and become a lifelong illness for some people. The virus can be a mild illness and last for as little as few weeks, but if not treated or healed on its own, it can turn out to be a lifetime struggle of the patient.

We are speaking of a virus that is most commonly spread trough medical equipment inadequate sterilization, unsafe injection practices like taking drugs and transfusions of unscreened blood.

On global level, there are 150 million people diagnosed with the hepatitis C infection. A big number of these people develop liver cancer or cirrhosis after a while of suffering from this disease. Out of these people, 700000 people die yearly from liver diseases related to the hepatitis C virus. This is still a huge number, considering the fact that antiviral medicines are known to cure 90% of those people who are diagnosed with this disease.

At this moment, there is no vaccine or definite cure for the hepatitis C virus. People who suffer from chronic hepatitis C infection have a risk of cirrhosis that reaches 30% within the first 20 years of the diagnosis.

Hepatitis C is a virus that can be found everywhere in the world. According to research, people with hepatitis C are found in biggest numbers in the Central Asia, East Asia and Africa. This leads to the conclusion that the infection can concentrate in general population, aside from the known fact that it is concentrated among people who inject drugs.

If you wish to avoid getting this infection, you should know the most common ways of hepatitis C being transmitted from a person to person. The most common ways are:

  • Trough injecting drugs with the sharing of equipment for injection
  • By reusing unsterilized or inadequately sterilized medical equipment such as needles and syringes in hospitals and other healthcare settings
  • Trough transfusion of unscreened blood
  • Trough unprotected sex with a person who has hepatitis C
  • Passed from a pregnant infected mother to the baby

You cannot get hepatitis C trough sharing food, water or even breast milk. Unlike what many people still think, a person cannot infect you with hepatitis C by hugging, kissing or sharing drinks and food.
