Management of Elevated TLC (44,000) in ALD with Negative Cultures
In a patient with alcoholic liver disease presenting with marked leukocytosis (TLC 44,000) and negative cultures, you must immediately perform a diagnostic paracentesis to measure ascitic fluid PMN count and treat empirically with cefotaxime plus albumin if PMN ≥250 cells/mm³, regardless of negative cultures, as this represents culture-negative neutrocytic ascites which carries the same mortality as culture-positive spontaneous bacterial peritonitis. 1
Immediate Diagnostic Approach
Mandatory Paracentesis
- A paracentesis must be performed before any confident diagnosis can be made—a "clinical diagnosis" without paracentesis is inadequate, even with peripheral leukocytosis of 44,000. 1
- Measure ascitic fluid absolute PMN count immediately, as this is more rapidly available than culture results and accurately determines who needs empiric treatment. 1
- Culture ascitic fluid in blood culture bottles to maximize yield, though 34.5% of culture-negative cases become culture-positive on repeat sampling. 1
Critical Context for ALD Patients
- Patients with alcoholic hepatitis represent a special case: they commonly present with fever, leukocytosis, and abdominal pain that can masquerade as SBP. 1
- Peripheral leukocytosis does NOT cause false-positive elevated ascitic fluid PMN counts in alcoholic hepatitis patients—an elevated PMN count must be presumed to represent SBP. 1
- These patients can develop true SBP superimposed on their alcoholic hepatitis, making paracentesis essential. 1
Treatment Algorithm Based on Ascitic Fluid PMN Count
If PMN ≥250 cells/mm³ (Most Likely Scenario)
- Start empiric cefotaxime 2g IV every 8 hours immediately, even with negative cultures. 1
- Add IV albumin 1.5 g/kg within 6 hours of diagnosis, then 1.0 g/kg on day 3—this reduces mortality from 29% to 10%, the lowest ever reported in SBP trials. 1
- Culture-negative neutrocytic ascites (PMN ≥250 with negative cultures) has similar signs, symptoms, and mortality as culture-positive SBP and warrants identical treatment. 1
- Delaying treatment until cultures grow bacteria may result in death from overwhelming infection. 1
Alternative Oral Therapy (Select Patients Only)
- Oral ofloxacin can substitute for IV cefotaxime only if the patient has NO vomiting, NO shock, NO grade II or higher hepatic encephalopathy, and serum creatinine <3 mg/dL. 1
- Only 61% of SBP patients meet these criteria, so most will require IV therapy. 1
If PMN <250 cells/mm³ with Symptoms
- Patients with convincing signs or symptoms of infection (fever, abdominal pain, unexplained encephalopathy, or unexplained deterioration) should receive empiric treatment regardless of PMN count until culture results are known. 1
- This addresses monomicrobial nonneutrocytic bacterascites, where 38% progress to SBP if symptomatic at presentation. 1
Additional Considerations for Peripheral Leukocytosis
Rule Out Alternative Causes
- The peripheral leukocytosis (44,000) itself does not explain ascitic fluid infection but may reflect:
Infection Surveillance in ACLF
- If the patient has acute-on-chronic liver failure (ACLF), consider broader antibiotic coverage (meropenem + daptomycin) due to high prevalence of multidrug-resistant organisms. 1, 2
- Each hour delay in first antibiotic dose increases mortality in ACLF patients. 1
- Lack of clinical improvement after 48 hours should trigger broadening of coverage and consideration of fungal infection. 1
Common Pitfalls to Avoid
- Never delay antibiotics waiting for culture results when ascitic fluid PMN ≥250—even a single dose of effective antibiotics causes cultures to show no growth in 86% of cases. 1
- Do not assume peripheral leukocytosis alone explains the clinical picture without sampling ascitic fluid—the PMN count in ascites is the critical determinant. 1
- Do not withhold treatment based on negative cultures if PMN count is elevated—culture-negative neutrocytic ascites requires identical management to culture-positive SBP. 1
- Remember that alcoholic hepatitis patients do not develop false-positive PMN elevations from peripheral leukocytosis—treat elevated PMN counts as infection. 1
Supportive Management
- Ensure complete alcohol abstinence, which is the single most critical intervention improving survival from 0% to 75% at 3 years. 3
- Implement aggressive nutritional therapy with frequent interval feedings (1.2-1.5 g/kg/day protein) as malnutrition affects up to 50% of ALD patients. 3, 4
- Monitor for hepatorenal syndrome, as albumin administration helps prevent renal failure (10% vs 33% without albumin). 1
