Pregnancy

Hepatitis C treatment is generally not recommended during pregnancy. There is not a lot of information on the effects of DAAs during pregnancy. Research is being done on taking DAAs during pregnancy so this may change in the future.

Treatment that includes ribavirin can cause severe birth defects and must not be taken during pregnancy. When a couple wants to have a baby, both partners should avoid using ribavirin for at least six months before trying to get pregnant.

A healthcare provider can help determine a treatment plan and timeline for a person who has hepatitis C and wants to have a baby.

Children and adolescents

Hepatitis C treatment for children over the age of 12 is available in Canada. It is recommended that children who require treatment for hepatitis C be connected to a specialist with experience treating the pediatric population.

Assessment Of Treatment Efficacy

Treatment may be considered effective if no HCV-RNA is detected in blood 12 weeks after the completion of therapy, which corresponds to the achievement of sustained virological response . The reliability of the result can be increased by repeating the test after another 12 weeks. In interferon-based therapy similar conclusions can be reached on the basis of results of HCV-RNA tests performed 24 weeks after the completion of therapy .

The efficacy of therapy should be assessed by PCR methods which provide the detection level of 15 IU/ml .

What Are The Signs And Symptoms Of Hepatitis C

As conditions go, hep C is seriously slymost people who have it dont show symptoms. In fact, about half of people with HCV don’t know they’re infected, according to the Mayo Clinic, and some people can live with it for decades before being diagnosed. If there are symptoms, theyre pretty mild. Think fatigue, muscle achescommon ailments you wouldnt automatically associate with hep C.

This is why the CDC recommends a hepatitis C screening: a simple blood test known as an HCV antibody test, for all adults aged 18 years and older at least once in their lifetime. Keep in mind, its not a standard test, so you have to ask for it. If that test is positive, youll likely be given a HCV RNA test to determine if you have an active infection.

Why is it so crucial to be diagnosed, if you don’t have any symptoms? When hep C hangs out in the system untreated for years, it starts affecting the liver and becomes chronic. More than half of people who become infected with HCV will develop chronic infection, according to the CDC. When that happens, symptoms may include:

  • Jaundiced skin

  • Confusion and slurred speech

  • Spider-like blood vessels on your skin

Chronic HCV can lead to serious complications, including cirrhosis , liver cancer, or liver failure. The liver performs a slew of vital functions, including:

When the liver is unable to deliver on even one of its important jobs, the damage wrought by hep C can be seriouswhich is why treatment is so crucial.

Interferons And Pegylated Interferons

The two most frequently used recombinant interferon preparations in clinical trials have been IFN alfa-2b and IFN alfa-2a , which differ from each other by only a single amino acid residue. IFN alfacon-1 , or consensus IFN, is a genetically engineered compound synthesized by combining the most common amino acid sequences from all 12 naturally occurring IFNs. Roferon-A was discontinued from the market in 2007 and Infergen was discontinued from the market in 2013.

The addition of propylene glycol molecules to IFN has led to the development of long-lasting IFNs that have better sustained absorption, a slower rate of clearance, and a longer half-life than unmodified IFN, which permits more convenient once-weekly dosing. The FDA has approved PEG-IFNs for the treatment of chronic hepatitis C.

Two PEG-IFN preparations are available for the treatment of chronic hepatitis C. PEG-IFN alfa-2b consists of IFN alfa-2b attached to a single 12-kd PEG chain it is excreted by the kidneys. PEG-IFN alfa-2a consists of IFN alfa-2a attached to a 40-kd branched PEG molecule it is metabolized predominantly by the liver.

A face to face consult with the specialist is not required and patients with complex needs will likely be referred to specialist care where appropriate.

What Does It Mean To Have A Successful Treatment What Is A Sustained Virologic Response

In an untreated state, the hepatitis C virus infects the cells of the liver and then continuously lives there, making copies of itself that circulate in the bloodstream. Antiviral medications can destroy the ability of the virus to reproduce, so the amount of virus in the bloodstream then decreases. The amount of virus in the blood is measured by aviral load.

Treatment is successful when the viral load drops toundetectablelevels, which means the virus cannot be detected in the bloodstream at all. The viral load becomes undetectable during treatment and remains undetected after treatment has ended. If there is still no detectable virus in the blood 12 weeks after the end of the treatment, the treatment was successful. This is called a Sustained Virologic Response .

A patient who has achieved an SVR is considered to be cured of the hepatitis C virus.

  • babies and children whose mothers have hepatitis C
  • anyone accidentally exposed to the virus, such as health workers
  • people who have received a tattoo or piercing where equipment may not have been properly sterilised

What Medications Treat Or Cure Hepatitis C

Hepatitis C treatments once involved months of injected interferons with up to 50% cure rates, and serious side effects. With newer medications, hepatitis C can be treated with oral combinations of medicines for several weeks. These are generally well-tolerated and yield sustained cure of virus from the blood in over 90% of cases.

The goal of treating HCV-infected persons is to reduce the risk of death, end-stage liver disease, and other liver-related adverse events by the achievement of a virologic cure which is determined by the sustained virologic response . Sustained virology response means complete disappearance of the HCV for at least 12 weeks after stopping treatment.
