Q

how are obesity and hepatitis linked

A

obesity is an inflammatory condition, resulting in an abnormal immune response to therapy.
The second mechanism hypothesises that obesity can cause insulin resistance and hepatic steatosis which leads to fibrosis, resulting in direct or indirect interference with the effect of interferon oh hepatocytes
The third mechanism hypothesises that obesity results in decreased bioavailability of peginterferon alpha.

Q

what happens in mechanism two in relation to antiviral therapy

A

In mechanism 2, obesity is hypothesised to cause insulin resistance and hepatic steatosis, leading to steatohepatitis and hepatic fibrosis, which can interfere directly or indirectly with the effect of IFN on hepatocytes.

Q

what is the pattern of liver enzyme elevations in co-amoxiclav induced liver injury

A

In these cases, the pattern of liver enzyme elevations is typically cholestatic with marked elevations in alkaline phosphatase and gamma glutamyl transpeptidase
In children, the pattern of serum enzyme elevations is much more likely to be hepatocellular
