Branching Case Study: Acute GI & Hepatology

Elena Vasquez · 62F · HCV Cirrhosis
Phase 1 of 4

Emergency Admission — Acute Variceal Hemorrhage

22:14 · Emergency Department

Elena Vasquez is a 62-year-old woman with known hepatitis C cirrhosis (Child-Pugh B, MELD-Na 18) brought by EMS after her family found her vomiting large amounts of bright red blood. She is pale, diaphoretic, and anxious. Exam: scleral icterus, spider angiomata across the anterior chest, abdominal distension with shifting dullness, and caput medusae visible at the abdominal wall.

Two large-bore IVs are established. NGT returns bright red blood. You suspect acute variceal hemorrhage. Blood is typed and crossed. Resuscitation with crystalloid is underway.

Question 1 of 8
Clinical Decision
After IV access and resuscitation are initiated, what is the most appropriate immediate pharmacologic intervention for suspected acute variceal hemorrhage?
⚠ Clinical Consequence — Inadequate Hemorrhage Control
Propranolol is prophylaxis only — not acute treatment. Vasopressin causes systemic vasoconstriction (myocardial ischemia, bowel ischemia) without the splanchnic specificity of octreotide and is no longer first-line. Without octreotide, portal pressure is not reduced and variceal bleeding continues. Ms. Vasquez requires emergency sclerotherapy and additional blood products. She arrives in the ICU more hemodynamically depleted — this will worsen the challenges she faces in Phase 2.
Phase 2 of 4

ICU Day 2 — New Complications Emerge

~18 hours after admission

Nursing alerts you: new fever and worsening abdominal distension. You perform diagnostic paracentesis at the bedside.

Paracentesis result: PMN count 310 cells/mm³ (SBP threshold: ≥250). Protein 0.5 g/dL. LDH normal. Culture pending.

Question 3 of 8
Clinical Decision
Based on the paracentesis PMN count of 310 cells/mm³, what is the correct diagnosis and immediate management? Culture results will not be available for 48–72 hours.
⚠ Clinical Consequence — SBP Undertreated
SBP is diagnosed by PMN ≥250 cells/mm³ — culture results do not change the indication to treat (cultures negative in ~40%). Waiting 48–72 hours for cultures delays life-saving therapy. The albumin omission eliminates the 30% mortality reduction from HRS prevention. Without immediate treatment, sepsis worsens. Ms. Vasquez's creatinine will rise more aggressively in Phase 3.
Phase 3 of 4

Day 4 — Neurological Change & History Revealed

ICU Day 4, 09:30
Day 4 labs: AST 386 U/L  |  ALT 178 U/L  |  AST:ALT ratio 2.2:1  |  Bilirubin 14.8 mg/dL  |  PT 22 sec (control 12)  |  INR 2.2  |  Creatinine 1.6 mg/dL (improving on terlipressin)

Social work reveals: Ms. Vasquez has been drinking 12–14 standard drinks per day for the past 3 years on top of her HCV cirrhosis. No active GI bleeding. No active infection (SBP responding to cefotaxime). No worsening renal failure.

Question 5 of 8
Clinical Decision
Nursing reports Ms. Vasquez is disoriented to time and place (oriented to person only), has bilateral asterixis, and is lethargic but rousable. Ammonia 148 mcmol/L. What is her West Haven grade of encephalopathy and the correct first-line treatment?
⚠ Clinical Consequence — HE Misgraded
Grade 2 = disorientation + asterixis + lethargy. Grade 3 = somnolence (patient difficult to arouse, not just lethargic). Intubating a Grade 2 patient is premature and carries procedural risks in a coagulopathic cirrhotic. Grade 1 is only mild confusion with shortened attention span — asterixis and disorientation place this patient firmly in Grade 2. Lactulose (not rifaximin monotherapy) is first-line for acute HE.
Phase 4 of 4

Day 7 — Step-Down Pending, New Problem

Hospital Day 7, 08:00

Ms. Vasquez has improved substantially. Encephalopathy resolved (oriented ×3, no asterixis). Creatinine 1.1 mg/dL. Prednisolone started day 4. Enteral nutrition via NGT running at goal since day 5. Transfer to step-down is being planned.

This morning: new right upper quadrant pain (8/10), rigors, and deepening jaundice. Bilirubin has risen again from its nadir.

RUQ ultrasound: dilated common bile duct 14 mm (normal ≤6 mm). Ms. Vasquez is now hypotensive, febrile, jaundiced, and newly lethargic — a change from her baseline this morning.

Question 7 of 8
Clinical Decision
The overnight hospitalist suggested switching Ms. Vasquez from enteral tube feeds to TPN, citing concern that gut feeding stimulates bacteria and worsens hepatic encephalopathy. How should the ACNP respond?
⚠ Clinical Consequence — Iatrogenic Malnutrition
TPN in liver disease increases infectious complications, worsens gut barrier dysfunction, and promotes bacterial translocation — the opposite of the intended effect. Protein restriction for HE is a 1970s myth disproven by clinical trials; it worsens sarcopenia, which independently worsens encephalopathy and increases mortality. Current EASL and ASPEN/SCCM guidelines: EN preferred over TPN, protein 1.2–1.5 g/kg/day, small frequent meals, late-evening snack to prevent overnight catabolism.

Questions Correct

Expert Debrief — The Interconnected Decompensations

Ms. Vasquez presented with simultaneous variceal hemorrhage, SBP, and incipient HRS — a cascade that requires parallel, time-sequenced intervention. Each wrong decision in this case made the next problem harder to manage.

Key Clinical Pearls

Variceal Hemorrhage: Octreotide (not vasopressin) is first-line. Ceftriaxone is added not just for infection prophylaxis but also independently reduces re-bleeding. Restrictive transfusion (Hgb 7–8 g/dL) — counterintuitive but mechanistically correct: the portal venous system has no valves, and over-transfusion raises portal pressure.

SBP: PMN ≥250 = diagnosis. Cultures are irrelevant to the decision to treat. Albumin (1.5 g/kg day 1 + 1 g/kg day 3) is not optional — it prevents HRS and reduces 3-month mortality ~30%.

HRS-AKI: After failed albumin challenge with no other AKI explanation, start terlipressin. Terlipressin partially reverses splanchnic vasodilation — the fundamental mechanism of functional renal failure in cirrhosis. Dialysis is a bridge; it is not treatment.

Hepatic Encephalopathy: West Haven Grade 2 = disorientation + asterixis. Grade 3 = somnolent. Lactulose is first-line. Protein restriction is a disproven myth — adequate protein (1.2–1.5 g/kg/day) is essential and does not worsen HE.

Alcoholic Hepatitis: MDF = 4.6 × (PT − control PT) + bilirubin. MDF ≥32 = severe; consider prednisolone 40 mg/day × 28 days. Assess response at day 7 with Lille Score — if Lille >0.45, stop steroids.

Nutrition: Enteral > parenteral always in liver failure. EN maintains gut barrier integrity. Protein restriction worsens sarcopenia and prognosis.

Ascending Cholangitis: Reynolds pentad (Charcot's triad + hypotension + altered mentation) = severe suppurative cholangitis = biliary emergency. Urgent ERCP within 24 hours. Do not schedule "elective" ERCP for a patient in septic shock.
