Will Community Pharmacies Be Able To Dispense These New Hepatitis C Drugs

Community pharmacists will be able to dispense the drugs. However, because these are new drugs, it may take time for pharmacies to order in sufficient stock to meet demand.

This means that patients may need to wait a couple of days after providing their script for the drugs to be available from their local pharmacy.

Proinflammatory Cytokines Induce Depression

Mercifully, for patients with hepatitis C, treatment with the cytokine interferon IFN-alpha has been supplanted by more effective and tolerable treatment options. But during the years of its clinical hegemony, IFN-alpha provided a unique model system for understanding behavioral and biological responses to chronic inflammation relevant to depression. Results from many studies have been quite consistent in demonstrating that IFN-alpha exposure produces a widespread increase in depressive and anxious symptoms, with a sizable minority of patients meeting full criteria for major depressive disorder within a month of commencing treatment. As reviewed in Miller and Raison , IFN-alpha treatment also produces all known biological changes associated with MDD more generally, including increased circulating pro-inflammatory cytokines, disruption of the diurnal cortisol rhythm and induction of glucocorticoid resistance, altered sleep physiology, and changes in monoamine metabolism, with many of these changes associating with increased depression during treatment . Supporting these findings are studies showing that even a single exposure to inflammatory stimuli induces depressive symptoms and depressive-style social cognitions in healthy volunteers, with these effects being strongest in women .

Can Hepatitis C Be Cured

Considerable progress has been made by past clinical trials in the medical treatment of hepatitis C. The rate of cure has increased with the development of direct-acting, all-oral antiviral regimens, and the length of therapy is much shorter. Treatment recommendations continue to change as new medicines become available. Treatment helps to reduce progression of liver damage to cirrhosis, may prevent liver cancer, and may prevent spread of the infection to other people.

Hepatitis C Virus Epidemiology

Hepatitis C Drugs Can Cost $84,000. This New One May Be ...

The World Health Organization estimates that there are 130 to 150 million cases of HCV infection worldwide, totaling 3% of the worlds population, with an average of 3 to 4 million new infections occurring each year. HCV infection causes substantial morbidity, ranging from cirrhosis to hepatocellular carcinoma , liver failure, and death. HCV infection and HCC were the leading indications for liver transplantation in the United States in 2014 however, the spectrum for transplantation is expected to shift as more patients with HCV infection are identified and successfully treated. According to estimates in 2013, 3.2 million Americans have chronic HCV infection, yet only 50% of patients infected with HCV know of their viral status of those, 7% to 11% are treated, and 5% to 6% have successful clearance of the virus. Furthermore, it is predicted that the burden of cirrhosis due to HCV infection could reach 37.2% by 2020 in infected patients.

In order to identify patients infected with HCV, recommendations have been made for routine testing in people born between 1945 and 1965 in people who have injected illegal drugs, received blood transfusion or organ transplantation prior to July 1992, or received clotting factor concentrates before 1987 in patients on long-term dialysis in children born to HCV-positive mothers in health care workers who have been exposed to HCV infection and in patients with evidence of chronic liver disease.

Why Are The New Hepatitis C Treatments Better

The new treatments are highly effective with a cure rate of 95-97 per cent. Treatment time is reduced to 12 weeks, drugs are tablets and there are very few side effects.

This is a major change from just a few years ago, when hepatitis C treatment time was from six to twelve months, with toxic side effects, and only a 50 percent chance of being cured.

This means that people newly diagnosed with hepatitis C, as well as those who have been living with chronic hepatitis C for many years, will now have access to a fast, effective and well-tolerated cure.

A Promise Of A Cure With A Cost

These new medicines are expensive. Researchers believe that as more come to the marketplace, prices will drop to stay competitive. If you have life-threatening liver damage due to the hepatitis C virus, you might be eligible for “compassionate care” rates, which can greatly reduce your out-of-pocket cost. Ask your doctor or case manager or directly contact the drug manufacturers.

Remember, there is no one-size-fits all treatment for chronic hepatitis C. Which medication is best for you depends on many things, including:

  • The amount of liver damage
  • Your previous treatments

Important Side Effects And Drug Interactions

Sofosbuvir is generally well tolerated its more common side effects include mild nausea, headache, and insomnia . The combination of sofosbuvir with amiodarone can cause life-threatening bradycardia . The addition of NS5A inhibitors does not lessen tolerability to any clinically relevant extent . Therapeutic elevation of the gastric pH lessens the bioavailability of ledipasvir, and thus the concomitant administration of sofosbuvir/ledipasvir with a proton pump inhibitor in a high dose is not recommended .

The side-effect profile and drug-interaction spectrum of the NS3/4A protease inhibitors are more complex. Simeprevir can evoke both nonspecific side effects and photosensitivity reactions patients should be advised to avoid direct exposure to sunlight and to use a topical sunscreen . All of the approved NS3/4A protease inhibitors can mildly or moderately elevate bilirubin and transaminase levels . A simultaneous, clinically relevant rise of both the bilirubin concentration and the transaminase concentrations is rare but presumably reflects hepatotoxicity and must be followed by discontinuation of the the protease inhibitor. The characteristic side effects of ribavirin are hemolytic anemia, dyspnea, an irritative cough, reduced exercise tolerance, and skin rash . As hemolysis elevates the bilirubin concentration as well, rises in bilirubin levels are more pronounced when ribavirin and NS3/4A protease inhibitors are given simultaneously.

    How Will My Provider Monitor Me During The Treatment

    Your provider will meet with you during treatment to review how well you are tolerating treatment and review laboratory results. Laboratory tests help keep tabs on your health, track the viral load, and determine your response to treatment. You will be given specific dates to go get your blood tested at the lab during and after the treatment.

    Pregnancy And Hepatitis C

    The new hepatitis C medicines have not been tested in pregnancy.

    You should not become pregnant while taking treatment as it could be harmful to unborn babies.

    If you’re pregnant, you must delay treatment until after your baby is born.

    Speak to your doctor before starting hepatitis C treatment if you’re planning to become pregnant in the near future.

    You’ll need to wait several weeks after treatment has ended before trying to get pregnant.

    Women taking ribavirin should use contraception during treatment and for another 4 months after the end of treatment.

    Men taking ribavirin should use a condom during treatment and for another 7 months after the end of treatment. This is because semen can contain ribavirin.

    If you become pregnant during treatment, speak to your doctor as soon as possible to discuss your treatment options.

    Helpful Tips While Taking Hepatitis C Medications

    • Always follow your health care providers’ advice, particularly the instructions on taking your medicine.
    • If you have to cancel an appointment, call your provider and schedule a new one as soon as possible.
    • Take good care of yourself. Eat well, drink 8 to 10 glasses of water each day, and try to get a full night’s sleep.
    • Learn about the hepatitis C medications you are taking. This includes special risks and warnings.
    • If taking ribavirin, use sunscreen, wear long sleeves and a hat, and limit sun exposure.
    • Write down your doctor’s name and phone number. Carry this information with you at all times.
    • Write the names and amounts of the medicines you are taking. Carry this information with you at all times.

    Can Hepatitis C Be Treated

    Treatment Choices for Hepatitis C in Patients with Kidney ...

    Yes, since 2010 enormous progress has been made in the treatment of chronic hepatitis C. New therapies called direct-acting antivirals are pills that act on the virus itself to eradicate it from the body, unlike older medicines like interferon injections which work by stimulating an immune response. These new treatments are very effective and can achieve cure rates of over 90%. In most situations now, there is no need for interferon, which was responsible for many of the side effects previously associated with HCV treatment. The new treatment combinations require shorter treatment durations , have reduced side effects and appear to be effective at all stages of the disease.

    Because these new therapies are very new, they remain very expensive. As such, drug coverage from both government and private companies may require that your liver disease has progressed to a certain stage before they are willing to cover the cost of these drugs.

    Your primary care physician may refer you to a specialist to determine whether you are eligible for treatment. A specialist will help you decide which drug therapy is best for you based on the severity of your liver disease, your virus genotype and whether or not you have been treated in the past.

    Antiviral Treatment In Childhood

    In an initial clinical trial, 12 weeks of treatment with sofosbuvir/ledipasvir yielded sustained virus eradication rates of 96% and 100% in patients aged 12 to 17 with chronic HCV infection of genotypes 1 and 4, respectively. The pharmacokinetic parameters of both substances were analogous to those seen in adults . Further cohorts of children aged 611 and 35 are now under evaluation, with drug doses of 33.7545 mg and 150200 mg . The findings are expected to become available in 2017.

    How Is Hepatitis C Treated

    Hepatitis C virus is treated with all-oral medications. These pills, calledantiviral medications, are usually taken once per day. These antiviral medications are extremely good at attacking the virus and preventing it from multiplying.

    Antiviral medications were not the original treatment for hepatitis C. Before 2014, the only treatment for hepatitis C was called interferon and ribavirin, taken as weekly injections under the skin, plus pills. Interferon treatment caused many unpleasant side effects and was not usually successful. Then a new generation of medications became available. These antiviral treatments are extremely successful at curing the virus and have very minimal side effects.

    Ribavirin is still sometimes prescribed to be taken along with the new antiviral medicines, but it has become more and more uncommon that ribavirin is needed at all. Ribavirin has some mild-moderate side effects. Ribavirin is a pill taken twice per day, as 2 or 3 pills in the morning plus 2 or 3 pills at night, depending on the patient’s body weight. Most patients do not need ribavirin.

    How can health-care personnel avoid exposure to HCV?

    Avoiding occupational exposure to blood is the primary way to prevent transmission of bloodborne illnesses among health-care personnel. To promote blood safety in the workplace, health-care personnel should consult infectious-disease control guidance from the National Institute for Occupational Safety and Health and from CDC. Depending on the medical procedure involved, Standard Precautions may include the appropriate use of personal protective equipment .

    What is the risk of acquiring hepatitis C after being accidentally exposed to HCV-contaminated blood or body fluids in the workplace?

    Although sharps injuries have decreased in recent decades due to improved prevention measures, they continue to occur, placing health-care personnel at risk for several bloodborne pathogens like hepatitis C. A recent analysis of several studies revealed an overall 0.2% risk for infection among those exposed to HCV-antibody-positive blood through needlestick or sharps injuries . Updated guidelines for management and treatment of hepatitis Cexternal icon are available to provide guidance for health-care personnel who become infected via exposure to contaminated blood at the workplace.

    Other than needlesticks, do other exposures place health-care personnel at risk for hepatitis C?

    What Are The Symptoms Of Hepatitis C

    Symptoms of Acute Hepatitis C Infection

    The majority of newly-infected patients identified with HCV do not have symptoms. The minority of patients who have symptoms typically have complaints of

    Symptoms of Chronic Hepatitis C Infection

    Chronic hepatitis C usually causes no symptoms until very late in the disease. Over the years or decades, chronic inflammation may cause scarring . Extensive scarring in the liver is called cirrhosis.

    Becoming infected with another viral hepatitis or other exposures that damage the liver in addition to hepatitis C can increase liver damage or even cause severe hepatitis. Having HIV infection along with HCV accelerates the progression of chronic hepatitis C to end-stage liver disease, sometimes shortening the course to a few years instead of decades.

    Who Is Most At Risk Of Contracting Hepatitis C

    You have a high risk of contracting hepatitis C if you:

    • use or have used injection drugs even if it was just once or many years ago
    • have received blood or blood products or an organ transplant before July 1990 in Canada
    • have been in jail or
    • have been injected or scratched during vaccination, surgery, blood transfusion or a religious/ceremonial ritual in regions where hepatitis C is common.

    You have a high moderate risk of contracting hepatitis C if you:

    • have tattoos or body piercing
    • have multiple sexual partners
    • have a sexually transmitted infection , including HIV or lymphogranuloma venereum
    • have experienced traumatic sex or rough sex or have used sex toys or fisting that can tear body tissue
    • have vaginal sex during menstruation
    • have received a kidney treatment
    • have received an accidental injury from a needle or syringe
    • have another infectious disease
    • were born to a hepatitis C infected mother or
    • have a sexual partner infected with hepatitis C.

    Hepatitis C is NOT passed from person to person by:

    • coughing, sneezing
    • breastfeeding unless your nipples are cracked and bleeding or
    • oral sex, unless blood is present.

    Nonstructural 3/4a Protease Inhibitors

    The RNA genome of hepatitis C virus is translated into proteins intracellularly to carry out viral function. A NS3/4A serine protease cleaves unprocessed polyproteins to create functional, individual proteins, a process blocked by protease inhibitors. The NS5A protein helps with HCV RNA replication regulation and viral assembly and packaging, and directly interacts with the RNA-dependent RNA polymerase . NS5A inhibitors prevent hyperphosphorylation of the NS5A protein and alter the proteins location from the endoplasmic reticulum. NS5B polymerase inhibitors have a high barrier to resistance and work broadly against genotypes with intermediate potency. Nucleoside inhibitors arrest RNA synthesis, while nonnucleoside inhibitors bind and disrupt the RdRp function.

    What Are Genotypes And Do They Matter

    Hepatitis C and Treatment Barriers

    Six different genotypes of hepatitis C have been identified. Genotypes 1 and 3 are the most common causes of hepatitis C in Australia and make up 90 per cent of all cases. They are important because they help determine the treatment you need. Unlike in the past, however, your genotype is not important in terms of the chance of cure. With the treatment drugs, all six genotypes have a very high chance of cure.
