Summary
Amphetamine use can trigger severe skin reactions like toxic epidermal necrolysis. This case highlights a severe presentation and complications, emphasizing the need for prompt diagnosis and management of drug-induced hypersensitivity.
Area of Science:
- Dermatology
- Toxicology
- Pharmacology
Background:
- Intravenous amphetamine use is associated with various adverse reactions.
- Drug-induced hypersensitivity reactions, including severe cutaneous adverse reactions (SCARs), can manifest following stimulant use.
Observation:
- A 48-year-old male developed a maculopapular rash after intravenous amphetamine use, progressing to widespread bullae.
- The patient presented with toxic epidermal necrolysis (TEN) affecting 90% of body surface area with tri-mucosal involvement.
Findings:
- Initial treatment with intravenous hydrocortisone was followed by intravenous immunoglobulin (IVIG).
- The patient experienced a poor response to IVIG and developed secondary infections, including MRSA, Candida, and Pseudomonas.
- Gradual re-epithelialization occurred over six weeks.
Implications:
- This case underscores the potential for amphetamines to induce severe cutaneous adverse reactions like TEN.
- Prompt recognition and management of TEN, including appropriate supportive care and infection control, are crucial.
- The role of IVIG in severe TEN requires further investigation, especially in the context of stimulant-induced reactions.
