What Is Chronic Hepatitis C Without Hepatic Coma

Questions For Your Doctor

Hepatic Encephalopathy Q& A with Dr. Yapp

When you visit the doctor, you may want to ask questions to get the information you need to manage your hepatitis C. If you can, have a family member or friend take notes. You might ask:

  • What kinds of tests will I need?
  • Are there any medications that might help?
  • What are the side effects of the medications you might prescribe?
  • How do I know when I should call the doctor?
  • How much exercise can I get, and is it all right to have sex?
  • Which drugs should I avoid?
  • What can I do to prevent the disease from getting worse?
  • How can I avoid spreading hepatitis C to others?
  • Are my family members at risk for hepatitis C?
  • Should I be vaccinated against other types of hepatitis?
  • How will you keep tabs on the condition of my liver?
  • How Is It Spread

    Hepatitis A is spread when a person ingests fecal mattereven in microscopic amountsfrom contact with objects, food, or drinks contaminated by feces or stool from an infected person.

    Hepatitis B is primarily spread when blood, semen, or certain other body fluids- even in microscopic amounts from a person infected with the hepatitis B virus enters the body of someone who is not infected. The hepatitis B virus can also be transmitted from:

    • Birth to an infected mother
    • Sex with an infected person
    • Sharing equipment that has been contaminated with blood from an infected person, such as needles, syringes, and even medical equipment, such as glucose monitors
    • Sharing personal items such as toothbrushes or razors
    • Poor infection control has resulted in outbreaks in health care facilities

    Hepatitis C is spread when blood from a person infected with the Hepatitis C virus even in microscopic amounts enters the body of someone who is not infected. The hepatitis C virus can also be transmitted from:

    • Sharing equipment that has been contaminated with blood from an infected person, such as needles and syringes
    • Receiving a blood transfusion or organ transplant before 1992
    • Poor infection control has resulted in outbreaks in health care facilities
    • Birth to an infected mother

    What Are The Symptoms And Signs Of Viral Hepatitis

      The period of time between exposure to hepatitis and the onset of the illness is called the incubation period. The incubation period varies depending on the specific hepatitis virus. Hepatitis A virus has an incubation period of about 15 to 45 days Hepatitis B virus from 45 to 160 days, and Hepatitis C virus from about 2 weeks to 6 months.

      Many patients infected with HAV, HBV, and HCV have few or no symptoms of illness. For those who do develop symptoms of viral hepatitis, the most common are flu-like symptoms including:

      Hcv Infection And Cerebrovascular Events

      In chronic HCV infection, cerebrovascular acute and chronic events have been reported with a higher prevalence than that observed in the general population in many cases, such neurologic conditions were associated with the presence of mixed cryoglobulinemia. Enger et al, in the largest retrospective study to date, including 21919 HCV-positive subjects and 67109 HCV-negative control subjects, reported a strict association between HCV and stroke, with a higher adjusted estimated risk of stroke for anti-HCV positive subjects . Gutierrez et al showed a close association between HCV infection and stroke in a retrospective study of subjects from the NHANES cohort during the period 2005-2010. However, it should be underscored that the two above studies have thus far been published only in an abstract form. Nonetheless, in a prospective study, involving a large population cohort from Taiwan, Liao et al established an association between HCV infection and stroke . Recently, in a large retrospective cohort from Taiwan, Hsu et al also found a higher risk of stroke in HCV infected subjects. Likewise, we recorded a higher prevalence of HCV infection in patients with stroke when compared with a large age- and gender-matched control group . In addition, HCV infection turned out to be an independent risk factor for stroke .

      Prevention Is The Best Medicine

      Even though hepatitis C rarely spreads within a household, if you or a family member have the disease, it’s wise to take precautions to prevent its spread especially if anyone in your home is immune compromised, or has cuts or open sores that increase the risk of infection.

      In general, use these common sense preventive tips:

      • Unless you are in a long-term, monogamous relationship, practice safe sex.
      • Clean up spilled or dried blood with a bleach-based cleaning solution and wear rubber gloves.
      • Do not share razors.
      • Do not share toothbrushes. “Though hepatitis C is not transmitted through saliva, there might be blood on the toothbrush,” Reau says.

      Note that hepatitis C is not transmitted by sharing eating utensils, hugging, kissing, coughing or sneezing.

      What Is Chronic Viral Hepatitis

      Hepatitis C Virus

      Patients infected with HBV and HCV can develop chronic hepatitis. Doctors define chronic hepatitis as hepatitis that lasts longer than 6 months. In chronic hepatitis, the viruses live and multiply in the liver for years or decades. For unknown reasons, these patients’ immune systems are unable to eradicate the viruses, and the viruses cause chronic inflammation of the liver. Chronic hepatitis can lead to the development over time of extensive liver scarring , liver failure, and liver cancer. Liver failure from chronic hepatitis C infection is the most common reason for liver transplantation in the U.S. Patients with chronic viral hepatitis can transmit the infection to others with blood or body fluids as well as infrequently by transmission from mother to newborn.

      Hcv And Cerebral And Systemic Inflammation

      As discussed above, chronic HCV infection is associated with systemic and local inflammation that may play a role in the pathogenesis of neuropsychiatric disorders as well. Huckans et al identified a proinflammatory profile in HCV-positive patients, significantly correlated with neuropsychiatric symptoms. In HCV infected patients, a local inflammatory response mediated by IL-8 and TNF- derived from HCV-infected brain macrophages/microglia has been described. Chronic activation of the immune system results in the production of such cytokines as IL-1, IL-6, IL-4, and TNF-, which are responsible for the neuronal changes underlying neurological impairment. Peripheral proinflammatory cytokines, like IL-1 and IL-6, can interfere with neurotransmitter systems thus predisposing to neuropsychiatric disorders indeed, increased levels of IL-6 have been reported to be associated with impairment of memory and spatial learning in chronic HCV infection moreover, an inverse correlation between plasma levels of IL-6 and both cognitive performance and executive function has been described.

      Relationship Of Symptoms And Spontaneous Clearance

      Overall, when combining data from multiple historical studies, approximately 25 to 35% of person with acute HCV infection have spontaneous clearance of HCV. The rates of spontaneous clearance are significantly lower in persons who are Black and in those individuals who have HIV coinfection. In contrast, rates of spontaneous clear are higher in females and in persons who acquired HCV in childhood. It has also been demonstrated that patients who present with symptomatic acute HCV infection and jaundice have higher rates of spontaneous clearance of HCV, in the range of 35 to 50%. The presence of jaundice is believed to reflect hepatic inflammation caused by a more robust initial immune response against HCV.

      Tests To Diagnose Hepatitis C

      How is Hepatitis C diagnosed?

      There are two main blood tests typically used to diagnose Hepatitis C. First, youll have a screening test that shows if youve ever had Hepatitis C at some point in your life. If this test is positive, youll have a second test to see if you have Hepatitis C now. These blood tests are described below:

      Hepatitis C antibody test

      This is the screening test used by doctors to show whether or not you have ever been exposed to Hepatitis C at some time in your life, by detecting antibodies in your blood. Antibodies are substances your body makes to fight off all kinds of infections. If you were ever infected with Hepatitis C, your body would have made antibodies to fight the virus.

      If the test result is:

      • Negative, it means you have not been exposed to Hepatitis C and further testing is usually not needed.
      • Positive, you have had Hepatitis C at some point. However, it does not tell you whether you have it now. Youll need to see your doctor for another test the Hepatitis C RNA test to determine if the virus is still active and present in your blood.

      Hepatitis C RNA Qualitative Test

      This test will determine whether or not you are currently infected with Hepatitis C. It is often called the PCR test because of the process used . It looks for the genetic material of the Hepatitis C virus in your blood.

      If the test result is:

      Recommended Regimens For Patients With Acute Hcv Infection

      PPT

      RECOMMENDED RATING Owing to high efficacy and safety, the same regimens that are recommended for chronic HCV infection are recommended for acute infection. IIa, C

      A number of studies have evaluated DAA treatment of acute HCV infection. Small single-arm, uncontrolled studies have evaluated 6 or 8 weeks of ledipasvir/sofosbuvir. One such study demonstrated 100% SVR with 8 weeks of ledipasvir/sofosbuvir among 27 men with acute HCV and HIV-coinfection . Investigators conducting another study evaluated 6 weeks of ledipasvir/sofosbuvir in a similar cohort . Among participants with genotype 1 infection, 79% achieved SVR12 71% of those with genotype 4 infection achieved SVR12 with this shortened regimen. Among the 6 individuals whose treatment did not lead to SVR12, there were 3 relapses . Three participants achieved SVR4 but were lost to follow-up . A phase 2 study followed a similar treatment protocol among 20 individuals with genotype 1 HCV monoinfection, all of whom achieved SVR12 .

      An open-label, single-arm, multicenter pilot study evaluated the efficacy of 6 weeks of the pangenotypic regimen glecaprevir/pibrentasvir among persons with acute/recent HCV infection . SVR12 was 90% a single virological failure occurred in a man with genotype 1a, HIV coinfection, and a viral load of 7.7 log10 IU/mL. This patient was successfully retreated .

      Life Expectancy And Prognosis

      Can you die from hepatitis? Technically, the complications of chronic hepatitis C are fatal. About 30,000 people in the U.S. die each year from cirrhosis.

      How long can you live with untreated hep C? The disease affects everyone differently, so thereâs no rule. But about 70% to 80% of people with will get chronic help C. Within 20 years, about 20% to 30% of those people will get cirrhosis. From there, it depends on what type of cirrhosis you have, your treatment, and if you can get a liver transplant.

      Can hepatitis C go away on its own? Yes. From 15% to 20% of people with hep C clear it from their bodies without treatment. Itâs more likely to happen in women and people who have symptoms. But it usually happens between 4 and 18 months after symptoms start.

      Is Chronic Viral Hepatitis C Contagious

      Hepatitis C can be passed from person to person. Most people with HCV get it through direct contact with blood containing the virus.

      People with hepatitis C can pass on the virus to others by sharing needles and syringes. Hepatitis C is easily transmitted among people who use intravenous drugs.

      Its also possible, but much less common, to acquire the HCV by:

      • sharing a razor with a person who has the virus
      • sharing a toothbrush with a person who has the virus at the same time that you have bleeding gums
      • having sexual contact with a person who has the virus

      Hcv And Direct Neuroinvasion

      Since HCV core and non-structural NS3 and NS5A proteins have been found to activate macrophages/microglia as well as astrocytes of infected patients, HCV proteins have been hypothesized to have a role in inducing neurotoxicity. HCV core protein has been described to mediate neuronal injury by suppression of neuronal autophagy and through immune activation. Specifically, HCV core protein has been demonstrated to activate both toll-like receptor 2 signaling and extracellular signal-related kinase neurotoxicity has been described to result from prolonged TLR2-mediated activation of ERK.

      Brain microvascular endothelial cells have been recently demonstrated to support HCV tropism and replication. HCV has been shown to induce apoptosis in these cells, leading to changes in the permeability of the blood brain barrier, microglia activation, and diffusion of pro-inflammatory cytokines into the CNS.

      However, evidence for an association between HCV neuroinvasion and neuropsychiatric disorders is currently scarce indeed, replication of quasispecies occurs at a very low level within the CNS and HCV RNA is almost undetectable in cerebrospinal fluid finally, a poor correlation between viral load and clinical manifestations has been reported.

      Baby Boomers Are Especially Vulnerable

      An Overview of Hepatic Encephalopathy

      “The hepatitis C virus didn’t have a name or a screening test until in 1989,” Reau says. “That means people born between 1945 and 1965, the group referred to as ‘baby boomers,’ are at highest risk of infection. They grew up before health care facilities started taking standard precautions, like not sharing vials of medicine among patients and requiring staff to wear gloves.”

      The CDC reports that baby boomers are five times more likely to have Hepatitis C than other adults, accounting for 75% of those living with the disease.

      These are some other reasons you may be at risk:

      • You have engaged in high-risk behaviors like IV drug use or unprotected sex
      • Your biological mother has/had hepatitis C
      • You received blood transfusions, an organ transplant or dialysis before 1989
      • You were or are currently incarcerated

      Recommended Testing For Diagnosing Acute Hcv Infection

      RECOMMENDED RATING HCV antibody and HCV RNA testing are recommended when acute HCV infection is suspected due to exposure, clinical presentation, or elevated aminotransferase levels . I, C

      Recommendations for HCV testing are also found in the Testing and Linkage to Care section.

      Diagnosis of acute HCV infection enables estimation of annual incidence rates and transmission patterns, thereby facilitating implementation and assessment of prevention programs. At the individual level, a diagnosis of acute infection expedites linkage to care, counseling regarding high-risk behavior, and timely interventions to reduce virus transmission and liver disease progression . Some persons involved in high-risk behaviors practice serosorting, defined as using HCV antibody serostatus to determine whether to engage in high-risk behaviors with certain individuals . Thus, undiagnosed acutely infected persons may be at greater risk of transmitting HCV to their presumably seronegative contacts than would be expected by chance.

      The best laboratory evidence to support a diagnosis of acute HCV infection is a positive HCV RNA test in the setting of a negative HCV antibody test , or a positive HCV antibody test after a prior negative HCV antibody test . There are rare instances in which these approaches may be misleading, such as in immunosuppressed individuals with impaired antibody production .

      Causes Associated With Acute Liver Failure

      Acute liver failure, also known as fulminant hepatic failure, can occur even if you dont have a preexisting liver disease.

      According to the Mayo Clinic, the most common cause of acute liver failure in the United States is acetaminophen overdose. Acetaminophen is an over-the-counter drug. You should follow the recommended dosage on the label. See your doctor immediately if you think you may have overdosed.

      Acute liver failure may also be caused by:

      • certain prescription medicines

      Acute liver failure can be genetic, passed along by an abnormal gene from one or both of your parents. If you have a genetic liver disease, youre more susceptible to liver failure.
