Q

what are the Presenting Features of CD and UC and how do they differ between one another?

A

In UC, most have diarrhea, rectal bleeding and abdominal pain

Blood diarrohoea more than a couple weeks = think about UC

CD almost always shows up on blood tests whereas UC is a bit more difficult as blood tests often more normal

Q

how is a diagnosis of IBD made?

A
  • History & Examination
  • Intestinal symptoms (Not a lot of signs normally)
  • Extra-intestinal manifestations
  • Exclude infection
  • Family History
  • Growth and sexual development (particularly for CD)
  • Nutritional status (take weight and height and plot on growth chart, not single one off measurement but longitudinal measurement)

Q

what Laboratory investigations can be done to make a diagnosis?

A

Full blood count & ESR (Do blood tests, particularly point you to CD):

  • Anaemia
  • Thrombocytosis
  • Raised ESR

Biochemistry:

  • Stool calprotectin (the key these days)
  • Raised CRP
  • Low Albumin (particularly in CD, tends to be due to leaking protein in gut and passing it out in stool, tends to be that more so than a nutritional problem)

Microbiology:

•No stool pathogens

Q

Differences to adult UC:

how common in Pancolitis adults and children?

A

Paediatric = >60%

Adult = 20%

In paeds closer to 80%

Much more severe and extensive phenotype

In children use more biologics

Q

what are some definitive investigaitons that could be done for IBD?

A

Radiology (especially Crohn’s disease):

  • MRI
  • Barium meal and follow-through (younger kids)

Endoscopy:

  • Colonoscopy & Upper GI endoscopy
  • Mucosal biopsy
  • Capsule enteroscopy
  • Enteroscopy

we struggle to get a look into the small bowel

Q

what is shown here?

A

Crohn’s disease

Typical ulcers (looks like slime of snail)

17
Q

what is shown here?

A

Could be either ……

These are the ones we put in the IBDU category

18
Q

histopatholigy - Pathology very helpful

what is shown here?

A

2 left you can see granuloma and you know you have CD – don’t see in all children with CD

Right is UC – disordered crypts, pus in crypts, great increase in inflammatory cells

19
Q

what are the Aims of Treatment?

A
  • Induce and maintain remission
  • Correct nutritional deficiencies
  • Maintain normal growth and development:

Growth is what makes management harder in children than adults

Inflammation and steroid use will affect growth and slow it

Try avoid steroids and get disease under control

Kids have more extensive and severe disease

20
Q

what are the methods of treatment?

A
  • Medical - Anti-inflammatory, Immuno-suppressive, Biologicals ( Infliximab)
  • Nutritional (Nutritional therapy particularly for CD) - Immune modulation, Nutritional supplementation
  • Surgical

Sometimes have to use surgery, use it for UC if we cant bring it under control, we do colectomies, pouch surgery

In CD its never curative so do as limited surgery as we can

21
Q

what is “Bottom-up” treatment for Crohn’s disease?

A

Start with gentle treatment

2nd step is things like immunomodulation that stops the inflammation coming back again

You can do surgery before biologics sometimes
