What is the De Ritis ratio used for?
used to differentiate possible causes of hepatitis
Tell us the different levels of the De Ritis ratio
> 2 –> alcoholic hepatitis
1 –> chronic cause (alcohol)
<1 –> acute cause (viral hep)
Diagnostics & expected results of Hep A
- Hep A IgM: positive
- Hep A antigen in stool: positive
Diagnostics & expected results of Hep B
Draw the Hep B chart
- the 5 phases
- HBsAg, Anti-HBc, IgM Anti-HBc, Anti-HBs
Diagnostics & expected results of Hep C
- Hep C antibodies: positive
- Hep C RNA: positive
Diagnostics & expected results of Autoimmune hepatitis
Anti-smooth muscle Ab: positive
Diagnostics & expected results of alcoholic hepatitis
- De Ritis ratio >2
- GGT: positive
Diagnostics & expected results of Non-alcoholic steatohepatitis
heterogenous appearance w/ fatty infiltrates on imaging
- NAFLD
