DIAGNOSIS OF HCV
1. Serologic assays (indirect assays)
Tests which detect anti-HCV are used to screen, and to diagnose hepatitis C infection. Enzyme Immunoassays (EIAs), Chemiluminescence Immunoassay (CIA) and Recombinant Immunoblot Assay (RIBA) are approved by the Food and Drug Administration (FDA) for clinical use (Colin et al., 2001).
The specificity of current EIAs for anti-HCV is greater than 99%. False positive results are more likely to occur in low-risk populations, however false negative tests can occur in the setting of severe immunosuppression such as HIV infection, organ transplantation, hypo- or agammaglobulinemia or in patients on hemodialysis (Kalantar-Zadeh et al., 2005).
RIBA has been used to confirm positive EIA.

The excellent marker for the resolution of HCV infection is sustained virological response (SVR), defined as undetectable HCV RNA in blood 24 weeks after finishing the treatment (Desmond et al., 2006). SVR is accompanied by reduction in hepatic inflammation and regression of fibrosis in patients without cirrhosis; but in patients with cirrhosis remain at risk of life-threatening complications as hepatic failure and portal hypertension (Younossi et al., 2007). The risk of HCC is reduced but not eliminated in patients who achieve SVR, and therefore screening for HCC must continue (Bruno et al., 2007). A-Type 1 IFNs: Type 1 IFNs Are natural proteins , which have variable actions, for example inhibition of HCV replication, recruitment of immune effector cells, induction of cell differentiation and induction of cytokine secretion (Feld et al., 2005)
B-Ribavarin:
It is purine nucleoside analogue, which works by inhibiting host enzyme inosine monophosphate dehydrogenase and HCV polymerase, so it acts on inhibition of RNA virus mutagenesis, replication of the viral
There are two different main types of diagnostic testing that can be done to determine if the Hepatitis C virus is present in your body. The Hepatitis C Antibody test is a screening test ordered by your physician that will show if you have ever been exposed to the virus in your lifetime. This test detects antibodies that your body would have formed in order to fight off the Hepatitis C virus.
Hepatitis C virus (HCV) is from the virus family Flaviviridae with an RNA envelope serving as it's genetic material. The genetic material (RNA) is HCV's pathogenic structure. The genome is positive sense single stranded RNA, which is very similar to mRNA and can be translated quickly to the host cell (Bauman 2012). Hepatitis C is an enveloped virus, and the RNA also lacks a proofreading ability after replication, which results in mutations coding for many genotypes within the host. This genetic variability makes it difficult for the host immune system to clear all the HCV infections. As one infection clears, another strain is being produced (Bauman 2012). The HCV antibody detected by ELISA(Wilkinson
A few years ago, Hepatitis C was a scary term for many of us. But, today the medical problem is curable as there are various and advanced ways available. The improvement in the treatment is especially notable because experts have worked harder to obtain this success. Still, there are some significant changes are left and hopefully they will be completed soon. Presently, the HCV treatments get rid of the virus in merely slightly more than half of all sufferers. The medicines also have unnecessary side effects that make it complicated or not possible for some patients to get them. HCV medication online available, but it is not worthy to take them without the concern of the doctor.
Require BOTH FibroTest > 0.59 AND Fibroscan > 9.5kPa. (The AASLD/IDSA HCV guidance panel notes that the
The abbreviations for this treatment stands for procaine-hydrochloride. Today, there’re countless identical byproducts. Also, there are different drugs, supplements and treatments similar to Gerovital H3. The active component in its non-derivative form is unalloyed procaine.
About 4.1 million people in Americans have the positive antibody to hepatitis C virus (HCV), and about 75 percent have permeant infection. Additionally, most of the infections happened 20 to 40 years ago, before the finding of HCV. Hepatitis C increased from 7,000 to 13,000 deaths in 2005. Furthermore, HCV develops slowly which increases the risk of severe complications in the infected people. Identification, death, and treatment are predicted to affect 35,000 by 2030. The Center for Disease Control (CDC) used antiviral therapy with PEGylated in clinical trials (Kalichman, Washington, Kegler, Grebler, Kalichman, Cherry, & Eaton, 2015). The CDC recommends a HCV one time test for people born between 1945 and 1965. The objective of this study was to thoroughly evaluate the amount of substance abusers infected with hepatitis C in the United States. Additionally, to observe the treatment of HCV. Currently Medicaid and Medicare repayment standards for sofosbuvir were calculated in all states, including the District of Columbia. Medicaid and Medicare covered the drug based on the following conditions; liver disease stage, HIV, and drug use. Approximately 42 states reimbursed the following criteria up to 74 percent for the drug sofobuvir. About two-thirds of the United States restricted the treatment centered on prescriber type. About 88 percent included drug abuse in their sofosbuvir admissibility measures. Finally, 50 percent required a date of abstinence and 64 percent required
The increasing number of citizens that are testing positive for Hepatitis C is shocking and the epidemic is just getting worse. One out of every one hundred people in the general population has Hepatitis C, but the ratio is higher in prisons. One out of every six inmates has Hepatitis C (Wegner, Rottnek, Parker and Crippin, 2014). Hepatitis C (HCV) is a blood disease that is caused by a virus and it affects the liver. Unfortunately there is no vaccine to prevent this disease and I have seen first-hand how ugly this virus is. I have worked in the medical field for the past 6 years and I have a very close friend who contracted HCV. Unfortunately, she was one of the many people that needed a liver transplant. HCV has infected four times as
The strain of genotypes is not differentiated by the severity of the disease. However, there will make a distinction in the regimen and the duration of the treatment (CDC, 2016). Treatment for chronic HCV is based on guidelines from the Infectious Diseases Society of America (IDSA) and the American Associations for the Study of Liver Diseases (AASLD). The criteria of who should receive the treatment include how much the virus in the body, the strain of hepatitis C, the degree of liver inflammation or damage, comorbidity, and response to previous treatment (Infectious Diseases Society of America [IDSA], 2016). The highest priority for treatment should give to a patient with advanced fibrosis and compensated cirrhosis (IDSA, 2016). Moreover, treatment priority should provide to the patient who has a high risk of transmitting the disease from and to others, such as individuals who are active injection drug users and hemodialysis patients (IDSA, 2016).
If someone is getting tested for Hepatitis C, they will first take an antibody test. This test will detect if antibodies are present in the blood, which will tell if the person has ever had Hepatitis C, not if they currently possess it (“Who Should”). If the antibody test comes back positive, a qualitative test will then be run. This test declares tells if someone is currently infected with Hepatitis C. A quantitative test can also be run, which shows the amount of Hepatitis C that is in the blood (“Who Should”). There are two main medications that are used to treat Hepatitis C. The first being Pegylated Interferon and another being Ribavirin. Both medications are used for the treatment of adult patients with chronic liver disease (FDA). These medications are used in place of the vaccine that has not been created for Hepatitis C. Therefore, Hepatitis C can be detected easily and is treatable.
There are a number of individuals who may be suffering from an illness and not even be aware they have an illness. One example of such illness is Hepatitis C (HCV). Hepatitis C is a severe disease of the liver. It is caused by the Hepatitis C virus (Centers for Disease Control and Prevention (CDC), 2015). As a result, Hepatitis C has been termed a silent epidemic (CDC, 2015). This is because a lot of individuals have Hepatitis C and don’t even realize they have the infection (CDC, 2015). As the infection begins to progress over time, it could cause acute issues to the liver (CDC, 2015). Those issues could be things like damage to the liver, the liver could fail to function, cirrhosis, or even cancer of the liver (CDC, 2015). However, screening for Hepatitis C will allow an individual to benefit from treatments that are available, hence eliminating the disease from the body and preventing the liver from undergoing any further damage (CDC, 2015).
The recombinant-based assay for HCV will detect HCV antibodies in blood samples of people with hepatitis C or who are carriers of HCV, but not in non-HCV individuals.
HCV can run years or even decades and may be undiagnosed. This is the reason that until the infection progressed so far because the virus infection and low probability are causing side effects or symptoms. In many cases, we found that HCV liver injury found by regular medical
Initial curative treatment in the early 1990’s used interferon and the antiviral ribavirin with a cure rate of 50% (Watson, n.d., p. 1). 2011 saw the invention of two antiviral medications, telaprivir and boceprevir, that increased cure rates to 70%. In 2013 newer drugs, simeprevir and sofosbuvir, were introduced with the later creating 90% cure rates in patients (Watson, n.d., p.gs. 1-2). Simeprevir (Sovaldi) was created for administration once per day over a minimum of a year (Gilead, 2014). Eradication of the disease in patients is effective in patients co-infected with HIV with low rates of side effects (Sulkowski, et al., 2014), highlighting its efficacy in complex patient populations. The cost of such treatment is $1,000 per day with an average cost for curative course exceeding $94,000 (Venteicher, 2014). The medication is FDA approved and prescribed readily, but patients are not receiving access to the medication through their insurers.
In general, a patient is infected with only one hepatitis C virus genotype. The strain of genotypes is not differentiated by the severity of the disease. However, there will make a distinction in the regimen and the duration of the treatment (CDC, 2016). Treatment for chronic HCV is based on guidelines from the Infectious Diseases Society of America (IDSA) and the American Associations for the Study of Liver Diseases (AASLD). The criteria of who should receive the treatment include how much the virus in the body, the strain of hepatitis C, the degree of liver inflammation or damage, comorbidity, and response to previous treatment (Infectious Diseases Society of America [IDSA], 2016). The highest priority for treatment should give to a patient with advanced fibrosis and compensated cirrhosis (IDSA, 2016). Moreover, treatment priority should provide to the patient who has a high risk of transmitting the disease from and to others, such as individuals who are active injection drug users and hemodialysis patients (IDSA, 2016).
Before blood transfusion and organ transplantation HCV screening test should be done, otherwise there will be a significant high risk to catch infection
