A female patient with systemic lupus erythematosus was prescribed prednisolone 60 mg daily for six weeks but continued the same dose for an additional six weeks without tapering. She was found dead in the bathtub. What is the most likely cause of death?

Most Likely Cause of Death: Perforated Duodenal Ulcer

The most likely cause of death in this patient is a perforated duodenal ulcer (Option A), resulting from prolonged high-dose glucocorticoid therapy without appropriate tapering or gastroprotection.

Clinical Reasoning

This patient received prednisolone 60 mg daily for 12 weeks total (double the prescribed 6-week duration) without tapering. This represents prolonged high-dose glucocorticoid exposure, which carries substantial gastrointestinal risks.

Why Perforated Peptic Ulcer is Most Likely:

Glucocorticoid-induced peptic ulcer disease is a well-established complication:

• High-dose prednisone (>30 mg/day) significantly increases peptic ulcer risk 1
• The FDA label explicitly lists peptic ulcer as a consequence of prolonged prednisolone use 2
• Events occur at rates of 1-4 per 100 patient-years with chronic medium-dose therapy 1

The clinical scenario fits perfectly:

• Found dead in bathtub suggests sudden catastrophic event
• Perforated peptic ulcer causes acute peritonitis, hypovolemic shock, and rapid death
• Patients on high-dose steroids often have blunted pain perception, delaying recognition of perforation until catastrophic
• The bathtub setting suggests she may have been experiencing abdominal discomfort and sought relief in warm water before sudden decompensation

Why Other Options Are Less Likely:

Option B (Hypertensive Cerebral Hemorrhage):

• While hypertension occurs with glucocorticoids (3-28 per 100 patient-years) 1, cerebral hemorrhage is not a predominant cause of death in SLE patients on steroids
• The bimodal mortality pattern in SLE shows early deaths from active disease/infection, late deaths from atherosclerotic cardiovascular disease 3
• Hemorrhagic stroke is not emphasized in glucocorticoid toxicity profiles

Option C (Acute Cerebral Vasculitis):

• This would represent active SLE, but she was on high-dose steroids for 12 weeks
• Active lupus causing death typically occurs early in disease course with inadequate treatment 3
• High-dose glucocorticoids should suppress active vasculitis

Option D (Intestinal Ischemia with Perforation):

• While theoretically possible, this is much rarer than peptic ulcer disease
• Not specifically highlighted in glucocorticoid adverse effect profiles
• Mesenteric vasculitis from SLE would be unlikely given the high steroid dose

Critical Glucocorticoid Toxicity Context

This case illustrates multiple guideline violations:

1. Excessive duration without taper: Guidelines recommend tapering high-dose glucocorticoids (>30 mg prednisone) relatively quickly 4

2. Lack of gastroprotection: Patients on medium/high-dose glucocorticoids require monitoring for comorbidities including peptic ulcer disease 1

3. Dose-related damage: Higher average daily prednisone doses predict organ damage (adjusted HR 1.03 per mg increase) 5

4. Modern SLE management emphasizes lower doses: Current guidelines recommend limiting prednisone to ≤5 mg daily for long-term use and avoiding prolonged high doses 6, 7, 8

Common Pitfalls to Avoid

• Never continue high-dose glucocorticoids beyond prescribed duration without reassessment
• Always provide gastroprotection (PPI) with medium/high-dose glucocorticoids
• Educate patients about the critical importance of not self-extending steroid courses
• Remember that steroids mask symptoms—patients may have advanced pathology with minimal complaints

The answer is A: Perforated duodenal ulcer 1, 2
