What is the management plan for a patient presenting with stroke-like symptoms, significantly elevated blood glucose, transaminitis, and a history of alcohol use?

Management of Stroke-Like Symptoms with Severe Hyperglycemia and Transaminitis

This patient requires immediate insulin therapy for severe hyperglycemia (glucose 1025 mg/dL) targeting 140-180 mg/dL, continued stroke workup with brain MRI and neurology consultation, admission to a monitored unit, and evaluation for diabetic ketoacidosis despite initial assessment suggesting otherwise. 1, 2, 3

Immediate Glucose Management

The severe hyperglycemia (1025 mg/dL) demands urgent intervention with intravenous insulin infusion, not just the 10 units subcutaneous insulin already given. 1, 2, 3

• Initiate continuous IV insulin infusion immediately using regular insulin at 1 unit/mL concentration, starting at 0.5 units/hour and titrating to maintain glucose 140-180 mg/dL 2, 3
• Monitor blood glucose every 1-2 hours initially, as this level of hyperglycemia significantly worsens stroke outcomes and increases risk of hemorrhagic transformation 1, 4, 5
• The target range of 140-180 mg/dL is based on American Heart Association/American Stroke Association guidelines and avoids the hypoglycemia risk associated with tighter control 1, 2, 3
• Avoid glucose-containing IV fluids - use normal saline for volume resuscitation 3

Critical caveat: While the patient was assessed as "not in DKA," with glucose >1000 mg/dL and anion gap of 16.8, reassess for DKA immediately by checking serum ketones, venous pH, and bicarbonate level, as the anion gap is elevated and DKA can present with focal neurological deficits mimicking stroke 6

Stroke Protocol Continuation

The initial stroke workup was appropriately initiated, but requires specific next steps:

• Proceed with brain MRI with diffusion-weighted imaging as recommended by tele-neurology to definitively assess for acute infarction, since CT may miss early ischemic changes 3, 6
• Administer full-dose aspirin (325 mg) as recommended by neurology consultation 3
• Continue cardiac monitoring for at least 24 hours to detect atrial fibrillation, which is present in many stroke patients and requires anticoagulation 1, 3
• Serial neurological assessments using NIHSS every 1-2 hours initially to detect any progression 3

Important consideration: The severe hyperglycemia itself can cause focal neurological deficits that completely mimic stroke (metabolic encephalopathy), and symptoms may resolve with glucose correction 6. However, this does not change acute management - treat both possibilities simultaneously.

Blood Pressure Management

• Do not treat the blood pressure unless systolic >220 mmHg or diastolic >120 mmHg, as lowering BP can extend the infarct in acute stroke 1, 3
• If antihypertensive therapy becomes necessary, use short-acting agents (labetalol or nicardipine) that can be rapidly titrated 1
• Avoid precipitous BP drops, which can worsen neurological status 1, 3

Transaminitis and Alcohol Use Evaluation

The elevated transaminases (AST 190, ALT 150) with history of alcohol use require specific assessment:

• Check hepatic function panel including PT/INR, albumin, and total protein to assess synthetic liver function, as this affects bleeding risk and medication metabolism 7
• Obtain right upper quadrant ultrasound to evaluate for fatty liver, cirrhosis, or other hepatic pathology
• Thiamine 100 mg IV should be administered immediately given alcohol use history to prevent Wernicke's encephalopathy, which can also present with focal neurological deficits 6
• Consider hepatitis panel and alcohol level if not already obtained

Admission and Monitoring Plan

• Admit to intensive care unit or stroke unit with continuous cardiac monitoring and capability for frequent glucose checks 1, 3
• The combination of severe hyperglycemia requiring IV insulin, acute stroke, and transaminitis necessitates intensive monitoring 2, 7
• Maintain NPO status until swallow evaluation is completed, as stroke patients are at high risk for aspiration 3

Additional Metabolic Workup

Given the extreme hyperglycemia in a patient denying diabetes history:

• Measure hemoglobin A1c immediately to determine if this represents undiagnosed chronic diabetes or acute stress hyperglycemia 1
• Check serum osmolality to assess for hyperosmolar hyperglycemic state 6
• Recheck anion gap, serum ketones, and venous blood gas to definitively rule out DKA, as the current anion gap of 16.8 is concerning 6
• The distinction between DKA and hyperosmolar state affects fluid management and insulin dosing

Critical Pitfalls to Avoid

• Do not rely solely on subcutaneous insulin for glucose >1000 mg/dL - IV insulin is mandatory for rapid, titratable control 2, 7
• Do not target glucose <140 mg/dL - this increases hypoglycemia risk without proven benefit and hypoglycemia can cause permanent brain damage 1, 2, 3
• Do not assume symptoms are purely metabolic - proceed with full stroke evaluation even with severe hyperglycemia, as both conditions may coexist 3, 6
• Do not overlook DKA - the anion gap and extreme hyperglycemia warrant definitive exclusion 6
• Do not delay insulin therapy - hyperglycemia worsens stroke outcomes and increases hemorrhagic transformation risk 1, 4, 5

Secondary Prevention Considerations

Once acute phase stabilizes:

• Comprehensive vascular risk factor assessment including lipid panel, as this patient likely has undiagnosed diabetes and multiple vascular risk factors 1
• Establish outpatient primary care and endocrinology follow-up for diabetes management 1
• Smoking cessation counseling if applicable 1
• Early rehabilitation assessment within 48 hours 3
