Hepatitis means inflammation of the liver due to a viral infection. There are a lot of causes for this, which includes lifestyle choices and some drugs or chemicals. The symptoms for this disease can take up to decades to develop. In Block fourteen we were able to cover viral hepatitis. Take this part one quiz and jog your memory.

- D.
Intravenous drug use
- 3.A 26-year-old woman presents complaining that her urine is dark and her stools pale. Patient history reveals that the patient has been to the Caribbean to see her long distance boyfriend. A serology panel reflects the following results: HAV IgG positive HBsAg positive HBcAg IgM positive HDV IgM negative HCV IgM negative What is the status of this patient?
- A.
Acute hepatitis A
- B.
Acute hepatitis B
- C.
Acute hepatitis C
- D.
Acute hepatitis D

Acute hepatitis E
- 4.Which of these is not a potential risk for HBV transmission?
- A.
Sexual intercourse
- B.
Needle sharing among intravenous drug users
- C.
Birth from an infected mother
- D.
Kissing
- E.
Multiple blood product transfusions
- 5.During hepatitis A infections, what is responsible for most of the liver damage?
- A.
Cytolysis by the virus
- B.
Antibody-dependent cell cytotoxicity
- C.
CD4+ T lymphocyte-mediated cytotoxicity
- D.
Phagocytosis
- E.
CD8+ T lymphocyte-mediated cytotoxicity
- 6.
- A.
CD8+ T lymphocytes clear the virus by destroying infected cells
- B.
NK cells clear the virus by destroying infected cells
- C.
Antibody-dependent cell cytotoxicity specifically destroys infected cells.
- D.
Hepatitis B virus replicates too slowly to induce significant liver damage.
- E.
CD8+ T lymphocytes clear the virus by purging viruses from infected cells in a non-cytolytic fashion.
- 7.A 35-year-old intravenous drug abuser presents to a free clinic complaining of fatigue and loss of weight. Physical examination reveals slightly yellow-tinged sclerae. A hepatitis serology panel reflects the following: HAV IgG positive HBsAg negative HBcAg IgM negative HCV IgG positive HDV IgM negative Further testing reveals the following: HIV-1 positive HIV-1 viral load 103 RNA IU/mL Which statement best applies to this patient?
- A.
HIV-1 co-infection will be of no consequence on the clinical outcome of patient.
- B.
Because the host immune response is strongly involved in the pathogenesis of viral hepatitis, liver damage will be limited in patient due to HIV-1-mediated immunosuppression.
- C.
Treatment of HIV-1 infection with reverse transcriptase inhibitors will also inhibit the viral reverse transcriptase responsible for transcribing the hepatitis viral RNA into gapped DNA, thereby also treating the hepatitis.
- D.
Patient could have avoided contracting a viral hepatitis altogether, had he received the vaccines currently available.
- E.
Patient will likely develop liver fibrosis more rapidly because of HIV-1 co-infection
- 8.A 35-year-old intravenous drug abuser presents to a free clinic complaining that his urine is black. Following a physical examination, patient most likely suffers from hepatitis. A hepatitis serology panel shows the following results: HAV IgG positive HBsAg negative HBcAg IgM negative HBcAg IgG negative HCV IgG positive HDV IgM negative HDV IgG negative What would be the most prudent course of action in this case?
- A.
Initiate treatment for both hepatitis A and hepatitis C.
- B.
Initiate treatment for hepatitis C only
- C.
Initiate treatment for both hepatitis A and hepatitis C, and have a PCR run for the possible presence of HBV.
- D.
Initiate treatment for hepatitis C, and have an RT-PCR run for the possible presence of HBV
- E.
Initiate treatment for hepatitis C, and have a PCR run for the possible presence of HBV
