Whether hepatitis C virus is not as volatile, the modern humanity, perhaps, would become one problem less.Unfortunately, this infection is one of the most adapted to survive in nature, and, therefore, to create a vaccine against it is impossible to date.
Hepatitis C - is the most severe form of viral hepatitis.Every year, the disease kills more than half a million people on the planet, and the incidence continues to grow rapidly.According to the forecasts drawn up by WHO in the coming decades it is hepatitis C will become the main problem of infectious disease physicians.
How is Hepatitis C?
main source of infection is considered to be patients with active hepatitis C and latent patients - carriers of the virus.HCV-infection is most commonly transmitted by the parenteral route - through infected blood or its components.Infection can occur when parenteral actions in health care facilities when providing dental services through needle syringes for injection, with acupuncture, tattooi
Expert Opinion: After sex is also infected a large number of people.
In 40% of cases the infection source is not identified.
Remember that hepatitis C is not transmitted through the arms, shaking hands or sharing glasses and dishes.There is no risk of contamination and airborne droplets (through saliva, sneezing or talking with the patient).Even if the home passes and transmission of infection from one person to another, then it is mandatory, followed by hitting a blood virus carrier in a person infected blood (for example, cut or getting injured).
Based on the foregoing, it can be concluded that the hepatitis C patients do not require isolation from others or in the creation of these special conditions for study or work.
diagnosis of hepatitis C: tests for the presence of virus in the patient
diagnosis of conduct and treatment of hepatitis C deal:
- in acute course of the disease - an infectious diseases doctor;
- the chronic course of the disease - a gastroenterologist or hepatologist.
accurate and precise diagnosis in this case is not possible without a series of instrumental and laboratory examination methods, in particular:
- linked immunosorbent assay (ELISA);
- polirazmernoy chain reaction (PCR);
- ultrasensitive test;
- biochemical blood analysis;
- test on the immune status of the organism.
immunoassay analysis is the study of viral hepatitis markers.Finding getting into the blood of harmful microorganisms, the immune system starts to produce antibodies to it - specific blood proteins.Immunoassay is built on the antigen-antibody reaction, when using standard serum antigens are specific antibodies, or vice versa, using antibodies to detect the presence of blood antigens.
Polirazmernaya chain reaction - this is the most sensitive and accurate on the date of diagnosis of various hepatitis method, including hepatitis C. This analysis is based on the detection of foreign particles (such as viruses and other microorganisms), got into the blood, even in very smallquantities by the laboratory copy of the genetic set of a microorganism.Thirty cycles of DNA copy of the desired fragments of the microorganism is sufficient to detect even one or two viruses in a single cell of the liver.
ultrasensitive analysis of hepatitis C virus is the most highly accurate method of diagnosis of the disease.By means of this diagnostic method can find out whether the infection is present in the body, even in the case where all other methods are powerless.Ultrasensitive test for hepatitis C is shown:
- if necessary to identify latent (inactive) form of hepatitis C;
- the presence of antibodies in the patient's blood to the hepatitis C virus and the inability to confirm the diagnosis by conventional methods to identify diseases;
- if necessary evaluation of the effectiveness of the therapy during treatment and for six months after its completion;
- if necessary for early detection of hepatitis C a person has come into contact with a carrier of the disease.
Biochemical blood analysis reveals the type and extent of damage to the liver, and the analysis of the immune status of the organism - to diagnose changes in the immune system.Timely and accurate detection and treatment of these pathologies is the basis without which it is impossible to rely on the conduct of a full treatment of hepatitis.
analyzes aimed at identifying the C hepatitis virus, play a key role not only in the accurate diagnosis, but also in the development of an individual treatment strategy for each individual patient.Ultimately, they are the key to the success of the treatment.Laboratory tests allow Hepatology get answers to the following questions:
- whether hepatitis C virus in the blood, or contact him to complete a full recovery sick person;
- if the virus is present in the human body, what is the viral load (the concentration of virus in the blood) and what is its genotype (whether it is easy to antiviral treatment);
- how quickly and actively progressing disease, which disease develops in the body;
- amazed how much hepatitis C liver, began whether the formation of hepatic fibrosis, and at what stage is the development of this pathology;
- what the genotype of the body of the patient, how likely is the complete removal of the virus from the patient's blood.
get answers to these questions, an experienced hepatologist able to diagnose the type of HCV infection, the degree of activity and the progression of the disease, with high reliability to predict the success of treatment and to determine the most appropriate each individual patient treatment strategies and tactics.
