What is the cause of epistaxis and nausea in a patient with normal platelet count, normal white blood cell count, elevated alkaline phosphatase, elevated chloride, and hypoglycemia?

Evaluation of Epistaxis and Nausea with Hypoglycemia

This patient requires immediate evaluation for HELLP syndrome or other hepatic dysfunction causing hypoglycemia, as the combination of epistaxis, nausea, elevated alkaline phosphatase, and hypoglycemia (glucose 69 mg/dL) suggests serious hepatic pathology rather than a primary bleeding disorder. 1

Critical Initial Assessment

The laboratory findings reveal several concerning abnormalities that point away from a simple epistaxis case:

• Hypoglycemia (69 mg/dL) combined with elevated alkaline phosphatase (107 U/L) suggests hepatic dysfunction with impaired gluconeogenesis 1
• Normal platelet count (219 K/µL) effectively rules out thrombocytopenia as the cause of epistaxis 2
• Elevated RDW (14.7%) and low MCHC (30.5 g/dL) may indicate early hemolysis or chronic blood loss 3
• Elevated MPV (12.8 fL) can reflect platelet consumption or turnover 3

Immediate Diagnostic Priorities

Rule Out HELLP Syndrome (if female of childbearing age)

The constellation of findings—particularly hypoglycemia with elevated alkaline phosphatase and epistaxis—mandates immediate evaluation for HELLP syndrome if this patient is pregnant or recently postpartum 3, 1:

• Obtain peripheral blood smear looking for schistocytes (hemolysis marker) 3
• Measure AST, ALT, LDH, and total bilirubin to assess liver function 3, 4
• Check coagulation studies (PT/INR, PTT) 3, 4
• Severe hypoglycemia occurs in HELLP syndrome due to hepatocellular dysfunction and impaired gluconeogenesis 1

Evaluate for Other Hepatic Causes

If HELLP syndrome is excluded, the elevated alkaline phosphatase with hypoglycemia requires investigation for:

• Acute liver failure or severe hepatic dysfunction (hypoglycemia is a marker of high mortality risk in severe liver disease) 1
• Diabetic bone disease (though less likely given the hypoglycemia rather than hyperglycemia) 5
• Obtain comprehensive hepatic panel including synthetic function tests 1

Management of Epistaxis

While investigating the underlying cause, manage the active epistaxis according to standard protocols 2:

First-Line Treatment

• Apply firm sustained compression to the lower third of the nose for 5 minutes or longer 2
• After removing any blood clot, perform anterior rhinoscopy to identify the bleeding source 2
• If a bleeding site is identified, apply topical vasoconstrictors and consider nasal cautery after anesthetizing the site 2

If Bleeding Persists

• Use resorbable nasal packing given the concern for underlying coagulopathy from hepatic dysfunction 2
• Consider nasal endoscopy to identify posterior bleeding sources if anterior rhinoscopy is unrevealing 2

Critical Management Considerations

Hypoglycemia Management

• Immediately correct hypoglycemia with dextrose administration 1
• Monitor blood glucose closely during the perioperative period if any intervention is required 1
• Hypoglycemia in the setting of liver dysfunction requires active surveillance 1

Coagulopathy Precautions

• Do not perform nasal cautery or invasive procedures until coagulation studies are available 3, 4
• If coagulopathy is present, administer fresh frozen plasma before any surgical intervention 3, 4
• Consider platelet transfusion if count drops below 50,000/mm³ before any procedure 3, 4

Common Pitfalls to Avoid

• Do not assume this is simple epistaxis given the metabolic derangements—the hypoglycemia and elevated alkaline phosphatase demand investigation for serious systemic disease 1
• Do not attribute epistaxis solely to local factors when systemic abnormalities are present; 45% of hospitalized epistaxis patients have contributing systemic illnesses 2
• Do not delay imaging or specialist consultation if hepatic complications are suspected, as conditions like hepatic rupture in HELLP syndrome are rapidly fatal without intervention 4
• Standard coagulation screening (PT, APTT, platelet count) is insufficient to diagnose von Willebrand disease, Factor XIII deficiency, or platelet dysfunction if bleeding disorder is suspected 6

Disposition and Monitoring

• If HELLP syndrome or acute liver failure is confirmed, immediate ICU admission is required for continuous monitoring 4
• Monitor continuously: blood pressure, central venous pressure, urinary output, ECG, oxygen saturation 4
• Obtain laboratory studies every 6-12 hours including CBC with platelets, comprehensive metabolic panel, liver enzymes, LDH, and coagulation studies 4
