INFLAMMATORY BOWELDISEASE IN CHILDREN CROHN’S DISEASE ULCERATIVE COLITIS INDETERMENANT (non specific) COLITIS
INFLAMMATORY BOWELDISEASE IN CHILDREN 1/3 of the incidence of IBD occurs in < 20 years of Age
INFLAMMATORY BOWELDISEASE IN CHILDREN Highest in Scandinavian Western European North American Jews > Non Jews Urban > Rural Lowest in Asian African South American
STRONG GENETIC PREDISPOSITION 10-25% in first degree relatives 7% in siblings Linkage with chromosome 16, 12, 14, 19, 6 & 1
IBD IN SAUDI ARABIA Not Uncommon Adult > Children UC > CD Milder than the west
PATHOPHYSILOLOGY Proinflammatory Cytokines & Eicosanoids Active inflammation Increase permeability & vasodilatation Symptoms & Signs Cont.#
PATHOPHYSIOLOGY SYMPTOMS / SIGNS: Diarrhea Abdominal pain Protein Loss Bleeding Electrolyte Loss Stricture Formation
EXPRESSION & DISTRIBUTION CROHN’S DISEASE 90% of patients have small bowel affected Classically terminal ileum 10-15% Only colon affected 60% Ileocolitis 20% have perirectal disease Cont.#
EXPRESSION & DISTRIBUTION Trans mural inflammation Fistulas arise when inflammation extends through the serosa (Bladder, Vagina, Perineum) Granuloma is the Hallmark of Chron’s disease, found in 30% of all cases.
EXPRESSION & DISTRIBUTION ULCERATIVE COLITIS 5% Proctitis 10-15% proctosigmoiditis 30-40% up to splenic flexure 50% pancolitis Almost always starts at the rectum Pathology limited to the mucosa Crypt abscesses, distorted architecture & goblet cell depletion, are typical
PRESENTATION ULCERATIVE COLITIS Commonly Bloody mucoid diarrhea frequent loose stool lower abdominal pain more with defecation • Fulminant disease (10-15% of PT’s) • > 6 Bloody stools per day • Abdominal tenderness • Fever, tachycardia • Anemia HypoalbuminemiaCont.#
PRESENTATION{CONTD} Constipation in proctitis Colonic carcinoma 1% by 10 years 1-2%per year thereafter Anorexia &Weight loss < Crohn’s Disease
PRESENTATION • CROHN’S DISEASE • Abdominal pain ( awakens patient from sleep) • Site of disease dictates the nature & site of pain • Ileum RT quadrant pain • Gastroduodinal dyspeptic pain • Diarrhea & Rectal Bleeding may resemble U.C. • Cont.#
PRESENTATION • Perianal disease(Fissures, fistulas & skin tags) • Intestinal obstruction is common • Abscesses (Interloop, intramesentric, • retroperitoneal, iliopsoas or subdiaphragmatic) • Carcinoma (Crohn’s Colitis)
EXTRAINTESTINAL MANIFESTATIONS SYSTEMICLOCALISED Fever Eyes {C.D. > U.C. } Joints Malaise Skin Anorexia + wt loss Liver {C.D. 40% > U.C. 10%} Bone Delayed Growth & Kidneys Sexual Development Vascular {C.D. > U.C.} Hematological Heart
EXTRAINTESTINAL MANIFESTATIONS EYE Uveitis, Episcleritis, Keratitis, RetinalVasculitis LIVER Sclerosing cholangitis U.C.>C.D. SKIN Erythema nodosum C.D.>U.C. Pyoderma gangrenosum U.C.> C.D.
EXTRAINTESTINAL MANIFESTATIONS - JOINTS Arthralgia or Arthritis, Knees > Ankles > Hips> Wrists> Elbow Most common localised manifestations {ankylosing spondylitis, sacroilitis}U.C.>C.D. - BONE Demineralization {Steroid+Rest+Vit D def,Decreased Protein} - KIDNEYS Ca oxalate,Ca phosphate,Uric acid. Inflammation
EXTRAINTESTINAL MANIFESTATIONS -VASCULAR Thrombocytosis Thrombophlebitis Activation of clotting cascade - HEMATOLOGICAL Anemia {B12 +Folic Acid def.} Effect of chemotherapy - HEART Perimyocarditis (good prognosis)
DIAGNOSIS • Hx & P/E: • Stool Analysis + C/S • WBC N or slightly elevated • ESR Elevated 70 % • Thrombocytosis 60% • Albumin
DIAGNOSIS Endoscopy Vs Radiology
ENDOSCOPY Sigmoidoscopy Colonoscopy Ileum Upper endoscopy
ULCERATIVE COLITIS Mucosa: Erythematus Granular Friable Loss of normal vascular
CROHN’S Aphus Lesions Psudopolyps Patchy Distribution Bx normal mucosa
RADIOLOGY -Upper G.I. Series Irrigular nodular and thickend bowel loops stenosis, ulcers & fistulas -Abdominal U/S & C.T. for complication of Crohn’s Disease
TREATMENT AIM: Relief of symptoms Improve quality of life Improve growth
TREATMENT Pharmacotherapy Nutrition Surgery
TREATMENT Pharmacotherapy: 5- Aminosalicylate (P.O. Knema) Sulfasalzine
TREATMENT Corticosteroids: Prednisone Budesonide
TREATMENT Antibiotics: Metronidazol Ciprofloxacin
TREATMENT Immunomodulators: 6- mercaptopurine Asathioprine Cyclosporine
TREATMENT • Anti-tumer necrosis factor -Alpha • Infliximab • CDP571 • Thalidomide • Others
TREATMENT • Clonidine (better than Sulfasulazine) • Na chromoglycate (No favorable effect)
ANTIDIARRHEAL DRUGS Loperamide : Frequency of Diarrhea Contraindicated in sever colitis
