Clinical Case for a Clinical Pharmacist
George, 40 years old male chronic alcoholic started taking
Sulfasalazine for his UC. After few days he suffered from severe
vomiting, severe pain upper abdomen, radiating to back, not releived
by some antispasmodic drug, the patient took at home. There was no
fever or history of GI or respiratory tract infection otherwise. There is
history of gall stones 1 year back.

Acute Pancreatitis (AP)
An inflammatory disorder of the pancreas characterized
severe pain in the upper abdomen
Increased serum concentrations of pancreatic lipase and
Complete recovery in most cases
Severe AP is associated with local complications
Acute fluid collection
Exocrine and endocrine pancreatic functions may remain
impaired for variable periods after an acute attack,
AP rarely progresses to chronic pancreatitis (CP).
Atlanta classification, acute pancreatitis can be divided
into two broad categories :
Interstitial edematous acute pancreatitis, : acute inflammation of
the pancreatic parenchyma and peripancreatic tissues, but without
Necrotizing acute pancreatitis: inflammation associated with
pancreatic parenchymal necrosis and/or peripancreatic necrosis.
According to the severity, acute pancreatitis is divided
into the following:
Mild acute pancreatitis:
Absence of organ failure and local or systemic complications
Moderately severe acute pancreatitis:
No organ failure or transient organ failure (<48 hours) and/or local
Severe acute pancreatitis:
Persistent organ failure (>48 hours) that may involve one or multiple organs
3% of all cases of abdominal pain admitted to
40 cases per year per 100,000 adults.
Ranges between 5 and 80 per 100,000 population
The highest incidence recorded in the United
States and Finland
In 80% of cases: mild and resolves without
Sex No predilection exists.
Age- 35-64 years
Causes by demographic
The most common causes of pancreatitis, are as
Western countries - chronic alcoholism and gallstones
accounting for more than 85% of all cases
Eastern countries - gallstones
Children - trauma
Adolescents and young
adults - mumps
Most common causes
Unknown (idiopathic pancreatitis).

Corticosteroids Interferon alfa-2b
AP is initiated by:
Premature activation of pancreatic zymogens (inactive
enzymes) within the acinar cells,
Pancreatic duct obstruction.
Release of active pancreatic enzymes directly causes local
or distant tissue damage.
Trypsin digests cell membranes and leads to the activation of other
Lipase damages fat cells, producing noxious substances that cause
further pancreatic and per pancreatic injury.
Release of cytokines injures the acinar cell and enhances
the inflammatory response
Injured acinar cells liberate chemoattractants
Attract neutrophils, macrophages, and other cells
to the area of inflammation
Increase vascular permeability promotes tissue
Pancreatic infection may result from colonic
Local complications: acute fluid collection, pancreatic
necrosis, abscess, pseudo cyst formation, and
Systemic complications include cardiovascular, renal,
pulmonary, metabolic, hemorrhagic, and central
nervous system abnormalities.
The initial presentation:
Moderate abdominal discomfort to excruciating pain,
Occurs in 95% of patients and is usually epigastric, often radiating to
the upper quadrants or back.
The onset is usually sudden
Tends to be steady and usually persists for several days
Nausea and vomiting occur in 85% of patients and usually follow the
onset of pain
Marked epigastric tenderness,
Hypotension, and low-grade fever.
In severe disease,
Bowel sounds are diminished or absent.
Dyspnea and tachypnea are signs of acute respiratory complications.
Following finding may benoticed according to
severity of the disease
Fever (76%) and tachycardia (65%); hypotension
Abdominal tenderness, muscular guarding (68%), and
distention (65%); diminished or absent bowel sounds
Dyspnea (10%); tachypnea; basilar rales, especially in
the left lung
In severe cases, hemodynamic instability (10%) and
hematemesis or melena (5%); pale, diaphoretic, and
Occasionally, extremity muscular spasm secondary to
Typical signs if necrosis
Cullen sign (bluish discoloration around the
umbilicus resulting from hemoperitoneum)
Grey-Turner sign (reddish-brown discoloration along
the flanks resulting from retroperitoneal blood
dissecting along tissue planes); more commonly,
patients may have a ruddy erythema in the flanks
secondary to extravasated pancreatic exudate
Erythematous skin nodules, usually no larger than 1
cm and typically located on extensor skin surfaces;
Diagnosis (guidelines 2013)
Two of the following:
characteristic (severe) abdominal pain,
serum amylase and/or lipase exceeding 3 times the
upper limit of normal, and/or
characteristic abdominal imaging findings (strong
recommendation, moderate quality of evidence).
A definitive diagnosis by
Surgical examination of the pancreas
If not possible then
recognition of an etiologic factor
clinical signs and symptoms
abnormal laboratory tests
Increase Serum amylase (20-110 U/L) and Serum lipase (0-160 U/L)
concentration more than 3 times the normal upper limits

Assessment of the patient’s hemodynamic status
immediately upon presentation,
Patients with systemic inflammatory response

admitted to an intensive care unit (ICU) or an
intermediary care setting
All patients should receive aggressive hydration,

little benefit derived from its administration after this
Within 24 hours of admission, patients with
concurrent acute cholangitis should undergo
endoscopic retrograde cholangiopancreatography
(ERCP); in high-risk patients,
The risk of severe post-ERCP pancreatitis should be
reduced through the use of postprocedure rectal
nonsteroidal anti-inflammatory drug (NSAID)
suppositories and/or pancreatic duct stents
The guidelines recommend against routinely using
prophylactic antibiotics in cases of severe acute
pancreatitis and/or sterile necrosis; however,
intervention in patients with infected necrosis may be
delayed through the use of antibiotics that penetrate
In mild cases of acute pancreatitis with no nausea and
vomiting, oral feeding can be initiated immediately;
Enteral nutrition should be used in severe cases to
prevent infectious complications, and parenteral
nutrition should be avoided
Regardless of lesion size, location, and/or extension,
intervention is not necessary for asymptomatic
pancreatic and/or extrapancreatic necrosis and/or
Surgical, radiologic, and/or endoscopic drainage in
stable patients with infected necrosis should be
postponed (for 4 weeks if possible) to permit a wall to
develop around the necrosis
Who should be treated in ICU
APACHE II score >8 in the first 24 hours of admission
Persistent (>48 hours) SIRS
Elevated hematocrit (>44 percent), blood urea
nitrogen (BUN) (>20 mg/dL), or creatinine (>1.8

For severe or mild with vomiting:
NPO: to minimize exocrine stimulation of the pancreas.
Naso-gastric (NG) aspiration in patients with profound pain, severe
disease, paralytic ileus, and severe vomiting
Enteral or parenteral nutrition if oral nutrition will be withheld for more

Intensive critical care (ICU):
To support the cardiopulmonary (heart and lung), liver and kidneys
that may fail due to RELEASE OF LARGE AMOUNTS TOXINS FROM
THE DEAD PANCREAS in the abdomen.
Almost all patients require intravenous nutrition.
Surgical treatment for severe acute pancreatitis
Only in a tertiary medical center by experienced surgeon
Complications in Acute pancreatitis
Pancreatic necrosis -Infected necrosis is almost always fatal without
Acute Fluid Collections are common in patients with severe
pancreatitis (occurring in 30%-50%).
Pancreatic abscess is a collection of pus adjacent to pancreas
presenting several months after attack.
Acute pseudocyst rupture or haemorrhage in pseudocyst.
Pancreatic ascites occurs when a pseudo-cyst collapses into peritoneal
cavity or major pancreatic duct breaks down and releases pancreatic
juices into peritoneal cavity.
Complications in Acute pancreatitis
Respiratory:Pulmonary oedema/Pleural effusions
Disseminated intravascular coagulopathy (DIC)
Renal dysfunction due to hypovolaemia, intra-vascular
coagulation. Usually avoided by adequate fluid
replacement plus/minus low-dose dopamine but acute
tubular or cortical necrosis can follow.

Evaluation of Therapeutic Outcomes
Periodic Assessment of:
Fluid and electrolyte status, and
Nutrition should be assessed periodically depending on the degree of
abdominal pain and fluid loss.
For sever cases in ICU, monitor for:
Vital signs, fluid and electrolyte status, white blood cell count, blood
glucose, lactate dehydrogenase, aspartate aminotransferase,
Serum albumin, hematocrit, blood urea nitrogen, serum creatinine,
international normalized ratio (INR).

aggravated by eating and relieved by abstinence from alcohol.
Steatorrhea (excessive loss of fat in the feces) with diarrhea and bloating
Azotorrhea (excessive loss of protein in the feces) are seen in most patients.
Weight loss may occur.
Diabetes usually a late due to pancreatic calcification.
Neuropathy is sometimes seen.

Surgical biopsy of pancreas is the gold standard for diagnosis of CP.
ERCP is the most sensitive and specific diagnostic test,
Serum amylase and lipase concentrations usually remain normal unless the
pancreatic duct is blocked or a pseudo-cyst is present.
The white blood cell count, fluid balance, and electrolyte concentrations
usually remain normal unless vomiting and diarrhea.
Abstinence from alcohol is the most important
