Collaborating with AI

Drafting rich case studies

Case studies are difficult to write and hard to find. Generative AI can help you by drafting case studies quickly, based on specifications you provide.

Use this prompt to generate a rich case study that your students can use in class. Modify the topics as appropriate, and you can even match these to your students’ interests to increase motivation.

Act as an expert toxicologist and pharmacologist with extensive experience in working with clinical cases.

Write a case study of an adverse drug reaction to methotrexate. Include detailed information about the patient, symptoms, the drug, timing and onset, and clinical presentation.

Also write a suggested analysis of the case study that students should provide, including management and interventions.

Here is an example of a completion from this prompt. Of course, as an expert, you should edit the AI’s outputs before giving it to students.

Sure, here is a hypothetical case study of an adverse drug reaction to methotrexate, as well as a suggested analysis guide that students should follow. Please note that this is a fictional case study for educational purposes only:

Case Study: Adverse Drug Reaction to Methotrexate

Patient Information:

  • Age: 65 years
  • Gender: Male
  • Medical History: Rheumatoid arthritis, hypertension, type 2 diabetes mellitus
  • Medications: Methotrexate (15 mg/week), Lisinopril (10 mg/day), Metformin (500 mg twice daily), Folic acid (5 mg/week, the day after Methotrexate)

Timing and Onset:

  • Week 1-8: Methotrexate initiated for the management of rheumatoid arthritis with no apparent issues.
  • Week 9: Patient reports mild nausea and fatigue.
  • Week 12: The patient is presented with severe mucositis, pancytopenia, and elevated liver enzymes.

Clinical Presentation:

  • Symptoms: Severe oral mucositis with painful ulcers, fatigue, shortness of breath, pallor, easy bruising, jaundice.
  • Vitals: BP 130/85 mmHg, HR 105 bpm, Temp 37.8°C (100°F), RR 22/min, SpO2 94%.
  • Lab Values:
    • Hemoglobin: 8 g/dL (normal: 13.8-17.2 g/dL for men)
    • Platelet count: 45,000/µL (normal: 150,000-450,000/µL)
    • WBC count: 1,500/µL (normal: 4,500-11,000/µL)
    • AST: 120 U/L (normal: 10-40 U/L)
    • ALT: 135 U/L (normal: 7-56 U/L)

Suggested Analysis for Students:

  1. Identify and Classify the Adverse Drug Reaction (ADR):
    • Based on the Naranjo Algorithm or another causality assessment tool, determine the likelihood that this is an adverse reaction to Methotrexate.
    • Classify the type of ADR according to the Rawlins and Thompson classification.
  2. Pathophysiology of the ADR:
    • Explain how methotrexate, as a dihydrofolate reductase inhibitor, can lead to the symptoms seen in this patient.
  3. Dose-Response Relationship:
    • Evaluate the dose of methotrexate the patient was on, and discuss if this dose is typical for the treatment of rheumatoid arthritis.
    • Discuss the role of folic acid supplementation in methotrexate treatment and its timing in this patient’s regimen.
  4. Risk Factors for this ADR:
    • Identify patient-specific (e.g., age, comorbidities) and drug-specific factors that may have contributed to the development of this ADR.
  5. Differential Diagnosis:
    • List other potential causes for this patient’s presentation and lab abnormalities, and explain why they are less likely than methotrexate toxicity.
  6. Management and Interventions:
    • Outline the steps to manage this patient’s condition. This should include:
      • Immediate discontinuation of methotrexate
      • Administration of leucovorin (folinic acid) for “rescue” in methotrexate toxicity
      • Supportive measures such as transfusions (if needed), hydration, and treatment for oral mucositis
      • Monitoring and management of hepatic function
      • Consideration of alternative treatments for rheumatoid arthritis
  7. Prevention and Monitoring:
    • Discuss strategies for preventing this type of ADR in future patients (e.g., more frequent monitoring, dose adjustments, alternative medications) and what monitoring parameters (e.g., CBC, liver function tests) should be in place for patients on methotrexate.
  8. Ethical and Legal Considerations:
    • Discuss the ethical and legal responsibilities of the healthcare professional in recognizing, reporting, and managing ADRs.
  9. Patient Education:
    • Develop a plan for educating this patient (and future patients) on the risks of methotrexate, the importance of regular monitoring, and the signs of toxicity that should prompt immediate medical attention.

Please note that methotrexate is a known immunosuppressant and cytotoxic agent, and its side effects, although often manageable, can be severe, as depicted in this hypothetical case study. Regular monitoring is essential when patients are prescribed methotrexate to catch potential side effects early and manage them effectively.
