Associations with PPI
HypoMg Low B12 C.diff Pneumonia AIN Dementia CKD Low BMD Gastric CA
Treatment Barrett’s Esophagus
Dysplastic: Endoscopic eradication + PPI
Non-dysplastic: PPI OD, rpt OGD 3-5 years
Dysphagia alarm symptoms (warrants OGD)
Weight loss, Anemia Hematemesis/Melena Onset >age 50 Emesis Odynophagia Persistent dysphagia despite PPI BID
*No alarm sx and <50yo + GERD –> PPI trial
Diagnostic Test for Achalasia
Treatment Achalasia
Good surgical candidate:
Poor OR candidate: Endoscopic botox > CCB/ nitrates eg nifedipine or ISDN
Risk factors for eosinophilic esophagitis
Male
Young (20-30)
Allergy/Atopy, Eczema, Asthma
Chronic rhinitis
Secondary causes of eosinophilic esophagitis
Pill esophagitis CTD Hypermobility syndromes HyperIgE syndrome Pemphigus Untx Achalsia Untx GERD
Treatment eosinophilic esophagitis
Complications of celiac disease
Malnutrition: weight loss, vitamin and mineral deficiency: Fe/B12 (anemia), Ca/vit D (osteoporosis),
Mild transaminitis
Dermatitis Herpetiformis (Dapsone after r/o G6PD)
Enteropathy associated T-cell lymphoma (consider if pt stops responding to gluten fee diet)
Celiac disease: Work-up
If high prob: OGD with duod bx + anti-TTG IgA +/- IgA
If low prob: 1st Anti-TTG IgA +/- IgA
If Bx + Anti-TTG IgA (or IgG if IgA deficient) + = CD
If both neg = no celiac
If Bx + TTG discordant-> HLADQ2/DQ8 to r/i or r/o
Indications to order HLA DQ2/DQ8 for Celiac Disease
Discordant biopsy and anti-TTG
Patient unable to comply with gluten-rich diet x3 months
Down Syndrome
Foods included in gluten free diet
BROW
Barley
Rye
Oats
Wheat
Pathology in Crohn’s vs UC
Crohn’s: Gum to bum (MC small bowel, ileocolitis, colonic)
Transmural inflammation, non-caseating
Skip lesions “cobblestone mucosa”
Strictures, Fistulas, clubbing
UC: Extends from rectum proximally
Submucosal/mucosal inflammation
Crypt distortion/atrophy/abscess
Contiguous, rare clubbing
Complications in Crohn’s vs UC
Crohn’s:
UC:
Induction Treatment Crohn’s Disease
Mild-Mod: Budesonide (if terminal ileum +/- R colon), Pred (colon only). **No role for 5ASA or thioprine
Mod-Severe:
Induction Treatment UC
Mild: Budesonide or 5-ASA (PO if extensive, PR enema if left sided colitis - sigmoid to splenic flexture, PR supp if proctitis <18cm)
Mod-Severe: Budesonide or Pred/Methylpred or anti-TNF (vedolizumab, ustekinumab, TNFi, JAK-2i acceptable if failed TNF)
Maintenance Treatment Crohn’s Disease
Mild-Moderate: Thioprine
Moderate-Severe: - Thioprine - MTX - Anti-TNF (with Aza or MTX) - *esp if fistulas - Anti-integrin (Vedolizumab) - AntiIL12/23 (Ustekinumab) NO JAKi (ONLY UC)
Maintenance Treatment UC
Mild: 5-ASA (PO/PR enema/PR sup)
Moderate-Severe:
Treatment Crohn’s Disease Complications
Classifying UC Severity
Mild: <4BMs/day Intermittent blood only Normal Hgb ESR <30
Severe: Vitals: T>37.8C, HR >90 >6BMs/day Frequent blood Low Hgb (<105) ESR >30 Dehydration requiring hospitalization
Definition Toxic Megacolon in UC
UC: Indications for colectomy
Diagnostic tests for H. Pylori
Biopsy histology
Biopsy culture
Stool Ag
Urea breath test
*Serology does not differentiate current vs prior infxn
Treatment H. Pylori
1st Line: PBMT x 14 days = PPI + Bismuth + Metronidazole + Tetracycline
OR
PAMC x 14 days = PPI + Amox + Metronidazole + Clarithro
Treatment failure: PBMT (if prior triple therapy) or PAL x14d (PPI/Amox/Levo)
*Urea breath test, biopsy, or stool Ag (NOT serology) >4 weeks post completion of tx
