Causes cirrhosis --> hepatoma 2-4%/year
-carrier status highest in infants--> children-->adults
-HBe Ag denotes viral replication. in some pts. have pre- core mutation of e-antigen & e-antigen can be negative in the presence of active replication. So check for HBV DNA
-Check for HBV DNA after acute Hepatitis to find out if pt has cleared infection or has gone to chronic hepatits

Acute pancreatitis.. causes
- gall stones (USA)
- alcohol (leading in men 2nd)

- type B gastritis
- gastric cancers
- mucosa associated lymphoma (MALT)
- treatment of H. pylori in low grade MALT results in tumors shrinkage or disappearance 50-80% of the time. Up to 30% of time, t (8;11) poor response to H. pylori therapy. Local RT required them. Await biopsy report before pronouncing cure. ***
298
zollinger-ellison syndrome
-duodenal bulb/ stomach ulcer--> multiple ulcers
-gastrinomas in. med duodenum, pancreas, porta hepatis. Associated w/ MEN I
-can present w/ PUD or diarrhea/steatorrhea (inactivates pancreatic lipase)
-fasting gastrin level elevated. IF non diagnostic then do,
-I.V secretin--> increase gastrin to >1000
-CT scan or somatostatin receptor scintigraphy localize tumor
-treat w/ PPI or resection of tumor
-others that increase gastrin level:
_pernicious anemia/chronic gastritis
_ renal failure
_hyperthyroidism
_PPI
299
All of the following are true about Zollinger Ellison
- MC earliest radiographic finding is a single duodenal ulcer
- ZE tumors are usually located on pancreas or duodenum
- 2/3rd of ZE are malignant and a quarter of them associated w/ MEN 1
- serum fasting of >1000mpg/ml w/ low pH is virtually diagnositc
- life expectancy is normal if curative surgery is done, otherwise life expectancy is 2 yrs
- recurrent duodenal ulcers or poor response to treatment is suggestive of ZE

5-ASA enema, hydrocoritsone enema
5-ASA supp or mesalamine supp h.s to tid --> cortisone foam
359
treatment for UC/ Crohn's?
- 5-ASA (mesalamine) is the active compound
- sulfasalazine= 5-ASA + sulfapyridine in the colon by bacterial action. Hence sulfasalazine would not be of much help in disease of small bowel, where there is not much bacteria.
- 5 ASA is the active component whereas sulfapyridine contributes to reversible infertility (esp in males) and leukpenia
- Olsalazine = 5-ASA + 5-ASA which is split in the colon
- Balsalazide = 5-ASA + inert product which split in colon
- Mesalamine compounds (Asacol & Pentasa) release dependent on Ph of colon .
- perianal abscess and fistula in CD, treat w/ anti TNF alpha, metronidazole with no efficacy.
- 6 Mercaptopurine + Azathriprine are steroid sparing!!!!
