A Rare Presentation of an Adverse Reaction to Minocycline

Area of Science:

• Clinical immunology
• Dermatology
• Pharmacology

Background:

• Drug reaction with eosinophilia and systemic symptoms (DRESS) is a rare but severe adverse drug reaction.
• Typically associated with antibiotics and anticonvulsants, DRESS presents with diverse systemic manifestations.

Observation:

• A 17-year-old female presented with symptoms mimicking serum-like sickness after initiating minocycline.
• Initial treatment and minocycline suspension led to symptom recurrence, including renal and respiratory compromise, upon corticosteroid taper.

Findings:

• Chest CT revealed interstitial pneumonitis, prompting a revised diagnosis of DRESS.
• Adjusted corticosteroid therapy led to significant symptom improvement, underscoring the importance of appropriate management.

Implications:

• This case emphasizes the diagnostic challenges in DRESS, particularly when initial presentations are atypical.
• Highlights the critical need for a comprehensive patient evaluation and a tailored, adaptive treatment strategy for DRESS.
• Underscores the importance of considering DRESS in patients with severe drug reactions, even with initial misdiagnoses.
