27
treatment for H. pylori
PPI and antibiotic
28
which type of ulcers occur more often
duodenal ulcers
29
how duodenal ulcers form
usually from H. Pylori which activates T and B lymphocytes and neutrophil infiltration and release of inflammatory cytokines which damage the gastric epithelium. they can also occur form acid and pepsin not deactivating when entering the duodenum
30
peptic ulcer disease can lead to high risk of
gastric cancer
31
sign and symptoms of duodenal ulcer
pain 2-3 hours after eating and in the middle of the night
32
sign and symptoms or gastric ulcer
pain right after eating
33
gastric ulcer caused by
a break in the mucosa that allow hydrogen ions to diffuse through the mucosa which causes damage and release of histamine
34
the release of histamine during gastric ulcers cause
increase blood flow from vasodilation and increased permeability. this all causes loss of plasma proteins and damaged vessels which causes bleeding
35
secretin does what
influences the environment of the duodenum by regulating secretions in the stomach, pancreas, and liver.
36
what can affect the effectiveness of H2 receptor antagonist
smoking
37
H2 receptor antagonist do what

38
example of H2 receptor antagonist
famotidine (Pepcid)
39
what other drugs should not be given with H2 receptor antagonist

46
what happens with glucose in liver disease patients
they can get hepatic diabetes from chronic high blood glucose levels
47
what is the byproduct of protein metabolism
ammonia
48
what does the liver do with ammonia
converts it to urea so if the liver is not functioning properly a build up of ammonia can occur
49
liver stores

50
vitamin D does what
helps absorb calcium
51
vitamin K does what
helps the clotting process
52
liver helps with the production of
blood plasma proteins
53
portal hypertension
abnormally high blood pressure in the portal venous system caused by resistance to blood flow
54
where does the blood in the hepatic portal vein come from
all the organs that play a role in digestion so the stomach, spleen, pancreas, and intestines
55
intrahepatic causes of portal hypertension
inflammation, fibrosis, and vascular remodeling that occur from cirrhosis or hepatitis
56
post hepatic causes of portal hypertension
impaired pumping of the heart or obstruction from Right HF or thrombus
57
consequences of long term portal hypertension
varices, splenomegaly, hepatopulmonary syndrome, portopulmonary hypertension
58
varices
distended veins from obstruction/pressure. blood then is shunted and pushed into other areas including the abdominal wall, stomach and esophagus
59
why are varies life threatening
because the vessels can rupture and lose a lot of blood
60
splenomegaly
enlarged spleen caused by increased pressure in the splenic vein which branches from the portal vein
61
most common symptom of splenomegaly
thrombocytopenia (low platelets)
62
hepatopulmonary syndrome
shunting occurs because pressure causes new vascular pathway and this new pathway does not pass the alveoli to obtain new oxygen. when the blood that went through the shunt meets up with the oxygenated blood that went through normal pathway the overall blood oxygen level is lower than if there wasnt a shunt. This causes hypoxemia
63
portopulmonary hypertension
the pressure buildup in the portal vein causes remodeling and pulmonary vasoconstriction
64
ascites
accumulation of fluid in the peritoneal cavity
65
most common cause of ascites
cirrhosis
66
factor that contribute to the development of ascites
decreased synthesis of albumin by the liver, portal hypertension, and splanchnic arterial vasodilation
67
what do decreased albumin levels and portal hypertension do to pressure gradient
cause capillary hydrostatic pressure to exceed capillary osmotic pressure which pushes water into the peritoneal cavity (ascites)
68
what is splanchnic arterial vasodilation associated with
increased production of nitric oxide by a diseased liver
69
what does increased nitric oxide do
can decrease effective circulating blood volume which activates RAAS (aldosterone) and antidiuretic hormone, which promotes renal sodium and water retention and overall accelerates portal hypertension and ascites
70
goal for ascites
palliative care (comfort) this can include paracentesis
71
what to watch out for during paracentesis
taking off too much fluid can cause the patient's blood pressure to drop dramatically
72

73
symptoms of hepatic encephalopathy
range from lethargy to coma
74
what can hepatic encephalopathy cause
astrocyte swelling from elevated ammonia levels, altered Blood brain barrier, and cerebral edema
75

obstructive or hemolytic cause
77
obstructive cause of jaundice can either be
extrahepatic or intrahepatic
78
extrahepatic causes of jaundice
liver still working but bilirubin accumulation because gallstone blockage of bile flow- considered conjugated
79
conjugated
hepatocytes functioning so something else is causing the problem
80
unconjugated
hepatocytes not functioning so they are the cause of the problem
81
intrahepatic cause of jaundice
hepatocyte dysfunction so liver has decreased ability to excrete bilirubin
82
hemolytic cause of jaundice
excesses hemolysis of red blood cells and liver can't keep up with the amount of RBC that need to be recycled
83
liver labs will be normal in what type of jaundice
extrahepatic jaundice
84
hepatorenal syndrome
functional kidney failure that develops as a complication of advanced liver disease, so the failure of the kidney does not happen because of kidney problems but because extrinsic factors due to liver disease
85
cause of hepatorenal syndrome
hypotension and vasodilation from variceal bleeding due to liver disease or hypotension due to abdominal paracentesis can causes prerenal acute kidney injury - hypoperfusion portalhypertension - accumulation of blood in kidney circulatory problems and cardiac impairment: such as right HF which decreases cardiac output
86
cirrhosis
irreversible, inflammatory, and fibrotic liver disease
87
causes of cirrhosis
hepatitis a/b/c, right HF, alcohol, autoimmune/hereditary, and idiopathic (unknown)
88
structural changes in cirrhosis are caused by
injury from viruses/toxicity from alcohol and fibrosis
89
fibrosis in the liver of cirrhosis patients is a consequence of
infiltration of leukocytes and release of inflammatory mediators

inflammation in ulcerative colitis is in the mucosal layer while Crohn's involves the entire intestinal wall
96
clinical manifestations in ulcerative colitis vs Crohn's
ulcerative colitis will have prominent diarrhea, bloody stools, and will not have weight loss. Crohn's will have weight loss due to small intestine malabsorption, may or may not have diarrhea, and blood in stools is less common
97
treatment of ulcerative colitis vs Crohn's
ulcerative colitis is cured with surgery of taking out the entire colon. Crohn's is not curable and is managed with surgery
98
out of ulcerative colitis vs Crohn's which can form into abscesses and necrosis and which can form into anal fistulas, obsesses, and obstructions

113
what are two things that occur in people with hypercortisolism aka cushings syndrome
their normal diurnal and circadian secretion patterns pf ACTH and cortisol are lost (disrupts their sleep and wake cycle) and there is no increase in ACTH or cortisol in response to stressors (normally there should be an increase in ACTH and cortisol during stress)
114
hormonal regulation occurs in response to
chemical factors, endocrine factors, or control from the nervous system in response to stimuli
115
negative feedback loop of hormones
occurs when there is a neural, chemical, or endocrine response to stimulus that decreases the synthesis and secretion of a hormone

120
negative feedback loop for adrenal gland regulation
it begins when low circulating corticosteroid hormones are noticed by the hypothalamus or when stress is present. hypothalamus responds by releasing corticotropin releasing hormone which causes anterior pituitary to release adrenocorticotropic hormone (ACTH), this stimulates adrenal cortex to release cortisol. once the threshold of corticosteroids is reached the hypothalamus inhibits the release of corticotropin releasing hormone (CRH).
121
glucocorticoid function
carbohydrate metabolism, protein breakdown in the muscle tissue, immune/inflammatory suppression, inhibition of bone formation, nerve function depression, and increase effect of catecholamine response
122

123
how do glucocorticoids promote carbohydrate metabolism
by promoting gluconeogenesis in the liver and decreasing glucose uptake thus promoting insulin resistance
124
calcitonin is secreted by the thyroid when
circulating calcium levels are too high
125
negative feedback loop of the thyroid gland
when circulating thyroid hormones are low the hypothalamus releases thyroid releasing hormone (TRH), this stimulates the anterior pituitary gland to secrete thyroid stimulating hormone (TSH), this stimulates the thyroid to release T3 and T4, T3 and T4 bind to proteins but once the unbound amount of circulating T3 and T4 levels are sufficient the hypothalamus halts the release of thyroid releasing hormone
126
what is required for the synthesis of T3 and T4
iodine
127
function of T3 and T4
regulates protein, fat, and carbohydrate catabolism, metabolic rate, and body heat production. maintains growth hormone secretion, cardiac rate, force, output, secretion of GI tract, and calcium mobilization. affects RR, RBC production, and CNS development
128
calcitonin function
lowers serum calcium levels by opposing bone resorbing effects of parathyroid by inhibiting osteoclast activity, lowers phosphate levels by decreases calcium and phosphate absorption in GI tract
129
what happens with weight during cushing syndrome
weight gain with a redistribution of fat
130
what happens with glucose in Cushing syndrome

131
what does cortisol induces insulin resistance cause
polyuria and glycosuria and 20% of individuals with Cushing syndrome will develop DM
132
what does cushing's syndrome do to the integumentary system
weakens the integumentary system due to loss in collagen which causes the skin to be thin and causes capillaries to become weaker and seen through the skin. this amounts for striae and bruising
133
what does protein wasting cause and what syndrome causes it
protein wasting occurs in cushing syndrome from the catabolic effect of cortisol. it causes muscle loss, bone wasting, and is the cause of the weakened integumentary system too
134
bone wasting causes
increase fracture risk, increase risk of osteoporosis, hypercalciuria, and risk of stones
135
if you have hypercalciuria then you most likely have
hypocalcemia
