1
Q

wha is pernicious anemia

A
  • Caused by a LACK of INTRINSIC FACTOR made by the gastric parietal cells which is required for vitamin B12 absorption

so basically the body cannot absorb vitamin b12 leading to =
- vitamin B12 deficiency

Q

when can pernicious anemia also occur

A
  • after GI surgery (i.e., gastrectomy, gastric bypass, small bowel resection involving the ileum)
  • In strict vegetarians since most of vitamin B12 come from meat
  • Excessive alcohol or smoking
  • More common in elderly than in younger patients*

Q

what are some typical anemia symptoms

A
  • Neurologic manifestations due to nerve demyelination
  • Loss of appetite, abdominal pain, beefy red tongue (atrophic glossitis), icterus, splenic enlargement
  • Treatment
    Parenteral or high oral doses of vitamin B12

Often unrecognized in older adults due to subtle, slow onset and presentation

Q

what are some treatment for pernicious anemia

A
  • Parenteral or intranasal administration of Vit B12 is the treatment of choice
  • Patients will die in 1-3 years without treatment
  • Long-standing neuromuscular complications may not be reversible
  • Increasing dietary cobalamin does not correct this anemia if intrinsic factor is lacking or if there is impaired absorption in the ileum
    Dose: 1000 mg of cobalamin IM daily for 2 weeks and then weekly until the Hgb is normal, then monthly for life

Q

Common causes of Folic Acid Deficiency Anemia (absence of neurological problems)

  • Malabsorption syndromes ( celiac disease, chron’s disease, small bower resection)
  • Increased requirement (i.e., pregnancy
  • drugs
  • alcohol abuse and anorexia

Q

what is celiac disease

A
  • genetic autoimmune disease
  • people can’t eat gluten because it will damage their small intestine
  • Gluten is a protein found in wheat, rye bread, and barley. It may also be in other products like vitamins and supplements, hair and skin products, toothpastes, and lip balm
  • affects each person differently and can occur in digestive system or other parts of the body
