  • Non-celiac gluten sensitivity has been coined to describe those individuals who cannot tolerate gluten and experience symptoms similar to those with celiac disease but yet who lack the same antibodies and intestinal damage as seen in celiac disease.
  • Early research suggests that non-celiac gluten sensitivity is an innate immune response, as opposed to an adaptive immune response (such as autoimmune) or allergic reaction.
  • Individuals with non-celiac gluten sensitivity have a prevalence of extra-intestinal or non-GI symptoms, such as headache, “foggy mind,” joint pain, and numbness in the legs, arms or fingers. Symptoms typically appear hours or days after gluten has been ingested.
  • Treatment: avoid gluten.

Delayed diagnosis of acute cholecystitis can lead to ___ (3)

A

Cholecystitis

  • Acute/chronic inflammation of gallbladder
  • Symptoms develop from mechanical obstruction, local inflammation, or both
  • Pain occurs when hormone cholecystokinin causes gallbladder to contract
  • More common in obese and women; frequently occur during pregnancy (FFF)

Risk Factors Associated with occurrence of Gallstones:

  • Body habitus: obesity,* rapid weight loss, cyclic weight loss
  • Childbearing : high levels of estrogen can cause cholesterol levels in bile to spike which can lead to development of gallstones
  • Drugs: ceftriaxone (Rocephin), postmenopausal estrogens, total parenteral nutrition
  • Ethnicity: Native American (Pima Indian), Scandinavian
  • Female gender
  • Heredity: first-degree relatives
  • Ileal disease, resection, or bypass
  • Increasing age
  • —Obesity defined as body mass index greater than 30 kg per m2

Clinical Presentation:

  • RUQ pain with radiation to the flanks and right shoulder
  • Occurs within one hour after eating a large meal, lasts for hours, and residual for days

  • Symptoms may be minimal in the elderly

Physical Exam:

  • Temperature
  • Abdomen: RUQ tenderness, involuntary guarding (early peritoneal irritation)
  • Murphy’s sign- painful splinting w/ deep inspiration and RUQ palpation
  • May palpate gallbladder in RUQ

Diagnostics:

  • CBC with differential,LFTs, GGT (gamma-glutamyltranspeptidase)
  • Gallbladder ultrasound to confirm gallstones: 95% sensitivity and specificity
  • A hepatobiliary iminodiacetic acid (HIDA) scan helps evaluate the function of the gallbladder and the bile ducts.
  • The GGT test is sometimes used to help detect liver disease and bile duct obstructions. It is usually ordered in conjunction with other liver tests such as ALT, AST, ALP and bilirubin. In general, an increased GGT level indicates that a person’s liver is being damaged but does not specifically point to a condition that may be causing the injury.

Management:

  • Cholecystectomy remains the primary procedure for the management of symptomatic gallstone disease. It is safe, has the lowest risk of recurrence, and provides 92 percent of patients with complete relief of their biliary pain
  • Laparoscopic cholecystectomy continues to have numerous advantages compared with the open technique
  • Oral dissolution therapy using bile acids (Urso Forte or Ursodiol) has successfully dissolved gallstones in an extremely limited patient population (reserved for patients unfit or unwilling to undergo surgery)
  • 25% of medically managed patients develop recurrent gallstones within five years

Acute cholecystitis develops in up to 10 percent of patients with symptomatic gallstones and is caused by the complete obstruction of the cystic duct
Delayed diagnosis of acute cholecystitis can lead to gangrenous cholecystitis, gallbladder perforation, and biliary peritonitis

Irritable Bowel Syndrome:

  • GI condition that is classified as functional because there are no identifiable structural or biochemical etiologies to explain its development
  • Chronic benign disorder: abdominal pain, bloating and disturbed defecation in absence of structural/biochemical abnormalities
  • Women affected more than men (2:1)
  • Most common presentation: abdominal pain and bloating; diarrhea &/or constipation
  • Rome criteria can help make diagnosis

Rome IV Criteria:

  • Functional GI disorders have a new definition. Rome IV defines them as follows: “Functional GI disorders are disorders of gut-brain interaction.
  • It is a group of disorders classified by GI symptoms related to any combination of the following: motility disturbance, visceral hypersensitivity, altered mucosal and immune function, altered gut microbiota, and altered central nervous system processing.
  • A person may experience problems with:
    1. The movement of food and waste through the GI tract (“motility disturbance”)
    2. Heightened experience of pain in the internal organs (“visceral hypersensitivity”)
    3. Changes in the gut’s immune defenses (“altered mucosal and immune function”)
    4. Changes in the community of bacteria in the gut (“altered gut microbiota”)
    5. Changes in how the brain sends and receives from the gut (“altered central nervous system processing”)

Rome Criteria for IBS:
Rome IV Criteria
- Recurrent abdominal pain, on average, at least 1 day/week in the last 3 months, associated with two or more of the following criteria:
- Related to defecation
- Associated with a change in frequency of stool
- Associated with a change in form (appearance) of stool.
- *Criteria fulfilled for the last 3 months with symptom onset at least 6 months before diagnosis.

Presentation:

  • Weight -usually stable
  • Abdominal exam: tenderness (usually LLQ) guarding, bowel sounds, masses, HSM
  • Rectal exam: tenderness, masses, blood
  • Diagnostics: CBC, ESR, TSH, glucose, lytes, BUN/Scr Fecal occult ; stool for O&P x 3; stool culture, Urea breath test
  • May have imaging: Abd u/s and x-ray, KUB, BE
  • If severe symptoms or unsure-proceed w/ colonoscopy

Management

  • Treatment is purely symptomatic and includes dietary modifications, medications, behavioral therapy, education and reassurance
  • Establish effective relationship with pt: education and reassurance is key
  • Symptom diary (timing, associated sx, feelings)
  • Predominate diarrhea: fiber to bulk stool; loperamide 2-4 mg QID (45 min before meals) can be helpful
  • Constipation: dietary fiber; laxative- Miralax preferred
  • Gas/Bloating: diet
  • Abdominal cramping: Bentyl 10-20mg TID, Levsin sl TID prn or Levbid
  • Stress reduction, biofeedback, exercise
  • Moderate to severe IBS, consider SSRI
  • Follow-up in 3-6 weeks then every 3-6 mos

Constipation:

  • Defined as a decrease in the frequency of bowel movements
  • Most commonly occurring gastrointestinal complaint
  • This disorder does affect the pediatric population but is a common complaint among older adults and more prevalent in women
  • Results in approx 2.5 million visits annually

Common causes (mostly functional)
- ignoring urge to defecate (most common)
- inadequate fiber and fluids in diet; sedentary
- metabolic, endocrine, neuro, colorectal disorder
Elderly patients:
- Diminished vitality, decreased activity, consequence of chronic illness and medications, poor dietary habits, and decreased fluid intake

Rome criteria:

  • Functional constipation categorized under new Rome criteria IV
  • IBS subtypes (constipation and diarrhea) are now based on abnormal stool type occurring at least 25% of days
  • New diagnoses added to this edition include reflux hypersensitivity syndrome, cannabinoid hyperemesis syndrome (CHS), opiod-induced constipation (OIC), and narcotic bowel syndrome (NBS). **
  • **“Many purists would say [these] are not really functional because [they have] a cause, but we have to rethink … this in the 21st century,” Drossman said. “What we’re really saying is that these are conditions that will mimic other so-called functional GI conditions, which … may have specific etiologies, and [they are] also consistent with our [new] definition [for functional GI disorders].”
