Management of Stroke with Leukocytosis

Initial Assessment and Management

• The American Heart Association recommends prioritizing airway, breathing, and circulation with oxygen supplementation to maintain saturation >94% 2, 3
• The American College of Cardiology suggests performing urgent brain CT or MRI to distinguish ischemic from hemorrhagic stroke 2, 4
• Essential investigations including complete blood count, electrolytes, renal function, glucose, cardiac biomarkers, ECG, and coagulation studies should be obtained 5, 2

Blood Pressure Management

• The American Heart Association recommends avoiding antihypertensive treatment unless systolic BP >220 mmHg or diastolic >120 mmHg 6, 7, 8, 2
• The American College of Cardiology suggests using short-acting agents with minimal cerebral vascular effects if treatment is required 6, 7, 8

Thrombolytic Therapy Consideration

• The American Heart Association recommends administering IV alteplase (0.9 mg/kg, maximum 90 mg) within 3-4.5 hours for eligible patients; leukocytosis alone is not a contraindication 8, 2, 3

Infection Surveillance and Prevention

• The Infectious Diseases Society of America recommends fever after stroke should prompt immediate search for pneumonia, which is a leading cause of post-stroke mortality 1, 2
• The American College of Physicians suggests administering appropriate antibiotics early when infection is identified 1, 2
• The Centers for Disease Control and Prevention recommends performing swallowing assessment using validated tools before allowing any oral intake 1, 2, 4

Stroke Unit Care and Complication Prevention

• The American Heart Association recommends admitting all stroke patients to a geographically defined stroke unit with interdisciplinary specialized staff 2, 4, 3
• The American College of Cardiology suggests administering subcutaneous anticoagulants or using intermittent external compression stockings for DVT prevention in immobilized patients 1, 2, 3

Metabolic Management

• The American Diabetes Association recommends correcting hypoglycemia immediately as it can mimic stroke symptoms and cause brain injury 6, 7, 3
• The American Heart Association suggests lowering markedly elevated glucose to <300 mg/dL while avoiding overly aggressive treatment that can cause fluid shifts 8

Monitoring Strategy for Persistent Leukocytosis

• The American College of Cardiology recommends performing frequent neurological assessments during the first 24-48 hours as approximately 25% of stroke patients deteriorate during this period 4
• The American Heart Association suggests using standardized stroke severity scales (NIHSS) for serial assessments 5, 2
