Viral hepatitis D
Hepatitis D (HDV, hepatitis delta) is caused by defective virus size of 37 nm, containing RNA, which is required for hepatitis B virus replication; exists either as a co-infection with hepatitis B or superinfection develops, leading to chronic hepatitis B virus infection Increases severity of hepatitis B, accelerating the progression of chronic hepatitis to cirrhosis, sometimes occurs as fulminant acute hepatitis_ Note that when infected with hepatitis D can be absent in the blood markers of hepatitis B - HbsAg antibody to hepatitis B core (anti-HBc) as hepatitis D virus is able to inhibit propagation of hepatitis B virus For the diagnosis of serum antibodies to hepatitis D (acute hepatitis D often have low antibody titers in chronic hepatitis D - higher titers)_ Viral hepatitis D is endemic for hepatitis B virus carriers who live in the Mediterranean Basin, parts of South America. On the other hand, percutaneous spread of infection among those note of virus HBsAg, injecting intravenous drugs hemophiliacs with transfusion therapy and, to a lesser extent, among gay men virus carriers HBsAg. Used for the prevention of hepatitis B vaccine, but not for virus carriers_ Markers: 1. Viral hepatitis D, the definition of RNA (NDV-RNA) Qualitative detection of hepatitis D virus RNA by PCR. 2. Antibodies total IgG and IgM to hepatitis D (anti-HDV IgG + antiHDV IgM) Method for detection of hepatitis D infection by identifying in the blood at the same time of IgG and IgM (total antibodies produced to hepatitis D). 3. Hepatitis G, the definition of RNA (HGV-RNA) Qualitative detection of HCV RNA by PCR G_ Case studies: 1.In the January-February this year in organized groups of adults and children were observed outbreaks of ARD_ Beginning of an outbreak was characterized by a high incidence of greater than several times the level of interepidemic morbidity. The clinical picture is dominated by first symptoms of intoxication, high (380 and above), fever, headache, later celebrated in some cough, others often expressed a runny nose. Occasionally observed cold sores on the lips_ What virus can be connected this disease? Based on this assumption, some clinical material should be obtained from patients and how to quickly decipher flash. List the methods of rapid diagnosis_ 2.In the summer in a camp an outbreak of acute intestinal diseases_ The results of bacteriological studies have shown that enteric bacteria are not the causative agent_ What research is needed to determine the conduct of the disease. 3. In the therapeutic clinic patient appeared jaundice and other symptoms zabolevaeniya, kotrroe could be diagnosed as viral hepatitis_ What are the possible reasons for its occurrence? What research is needed to confirm dipgnoza spend? 3.Cherez 2 months after blood transfusion in a child in the family developed jaundice_ What type of hepatitis may include a zabolevaenie? How to prove? 4.The appointment with a local doctor with the child's mother came_ 3 months ago, the child has been vaccinated with DTP_ The child yellowness of the sclera, enlarged liver_ Two weeks before the appearance of jaundice in a child there was a decrease of appetite, nausea, repeated vomiting, abdominal pain, and diarrhea. In addition to this child in the family still have children_ They are healthy_ Your presumptive diagnosis? Which methods of microbiological diagnostics are needed to confirm the diagnosis_ Name the mode of transmission in this case_ Questions blitz - the survey: 1. Taxonomy of herpesviruses_ 2. herpesvirus of importance in dental practice_ Ситуационные задачи: 1.В лабораторию поступил материал (кусок парашюта) для исследования на особо опасную инфекцию.
