AIDS Cholangiopathy, opportunistic infection, keep this in mind.
Opportunistic infection of the biliary tree by cryptosporidium parvum and CMV,
these organisms that we've looked at earlier with immunocompromised patients specifically with AIDS.
Remember that the most common cause of diarrhea in an AIDS patient is cryptosporidium parvum.
If it’s CMV infection anywhere for example in the esophagus,
then you should be thinking about immunocompromised patient.
Your CD4 count usually would be less than 100, there would be right upper quadrant pain,
hepatomegally and Alk Phos will be elevated.
ERCP here once again will show you intra and extra-hepatic dilation with or without,
there could be structuring, without the dilations.
Be careful, do not confuse this with primary sclerosing cholangitis.
There’s every possibility with AIDS that you might have gall bladder damage.
Management -- endoscopic management of that narrowing, the strictures.
