1. Ulcerative Colitis

2. Definition
is an idiopathic chronic inflammatory disorder limited to
the colon.
Ulcerative colitis is a lifelong illness that has a profound
emotional and social impact on patients who are
affected.
Ulcerative colitis as visualized with a colonoscope.
The rectum is involved in more than 95% of cases,
although some authorities believe that the rectum is
always involved in untreated patients. Ulcerative
colitis extends proximally from the anal verge in an
uninterrupted pattern to involve part or all of the
colon.

3.  Prevalence rates may be lower in South America, Asia,
and Africa.
 Race
 Ulcerative colitis occurs more frequently in white
people.
 The incidence of ulcerative colitis is reported to be 2-4
times higher in Jewish people. However, population
studies in North America do not completely support this
assertion.
 Sex
 Ulcerative colitis seems to have a female
preponderance. Ulcerative colitis affects 30% more
females than males.
 Age
 The incidence of ulcerative colitis peaks in people aged
15-25 years and in people aged 55-65 years, although
it can occur in people of any age.1

4. Pathogenesis
 Dysbacteriosis – toxic and allergic effect and
inflam colon
 Abnormalities of neurohumoral regulation of
bowels due to dysfunction of vegetative and
endocrine system
 ↑colon mucous penetrability for protein
molecule and bact antigens
 Wall damages and formation autoantigens
 Formation of immune complexes
 Development inflam-n of colon

7.  Syndrome of Intoxication
 Syndrome of systemic manifestations:
 Polyartritis, sacroileitis

pustular and urticary rush.
 Eyes: iritis, iridicyclitis, panophtalmitis, episcleritis
 Liver: HAH, cirrhosis, portal fibrosis, fatty dystrophy
 Mouth: pathos stomatitis, glossitis, gingivitis,
 May be appears nephrotic s-m,autoimune tyreoidit
 autoimmun hem anemia
 Dystrophic syndrome: weight loss, palleness and dry skin,
hypovitaminosis, shedding hair, nail changes

13. Treatment
 Medical Care
 Prior to initiating therapy, an accurate assessment is needed;
this assessment should include a thorough history and physical
examination. A colonoscopy is preferable.
 An appropriate medical regimen for ulcerative colitis is
determined by the severity and the extent of disease.
 Aminosalicylates, such as mesamine, have generally been the
initial drug therapy for IBD.
 The need for dosing mesalamine multiple times a day has been
recently questioned. A study by Sandborn et al compared the
efficacy and safety of once-daily delayed-release mesalamine
(Asacol 400 mg) with twice-daily dosing for remission
maintenance.2 At 6 months, 90.5% of patients receiving once-
daily dosing had maintained clinical remission, compared with
91.8% of those receiving twice-daily dosing. At month 12, both
groups had identical clinical maintenance rates of 85.4%.2

14. Surgical Care
 Considerations for total colectomy are as follows:
 Refractory disease with failure to medical therapy
 Evidence of carcinoma or dysplasia
 Severe hemorrhage
 Fulminant colitis not responsive to treatment
 Toxic megacolon
 Perforation (free or walled-off)
 Obstruction and stricture with suspicion for cancer
 Systemic complications from medications, particularly
steroids
 Failure to thrive in children
