Minocycline-Induced DRESS: Evidence for Accumulation of the Culprit Drug

Abstract: Background: Minocycline-induced drug rash with eosinophilia and systemic symptoms (DRESS) may have a prolonged course, especially in African and African-American patients. Objectives: To determine if a prolonged course of minocycline-induced DRESS was associated with an accumulation of the culprit drug. Patients and Methods: We determined plasma and skin levels of minocycline in patients with minocycline-induced DRESS. We investigated the genetic polymorphisms of enzymes potentially involved in the detoxificat… Show more

“…18 Minocycline-induced DRESS occurs mainly in patients with Fitzpatrick skin phototypes V and VI. 19 The plasma half-life of minocycline is approximately 18 hours. In a group of 9 patients with minocycline-induced DRESS syndrome with skin phototypes V and VI; 6 patients had significant plasma and skin levels of minocycline ranging from 11 days to as long as 17 months after discontinuation of minocycline therapy.…”

“…Formation of a melanin-minocycline complex in patients with skin phototypes V and VI may explain why these patients typically experience a more severe and prolonged course of DRESS syndrome. 19 The genetic predisposition to minocycline-induced DRESS syndrome in patients of African descent may be related to a variation in detoxification enzyme activity. Minocycline is metabolized in the liver, and current research is focused on identifying genetic variants in major histocompatibility complex haplotypes, cytochrome P450, and glutathione S-transferase that may be shared by individuals with DRESS syndrome.…”

“…7,58,71,78,90 The drugs incriminated were retained after chronology, signs, and symptoms had been analyzed according to the methodology described by Bégaud et al 3 For each patient, 1 or 2 drugs were finally considered at least possibly (positive response to its/their withdrawal with no further investigation) or probably (positive rechallenge) responsible. This interval was chosen based on previous reports on DIHS.…”

“…[90] The mechanism of hypersensitivity reactions could be identified as a cytotoxic immune reaction against alveolar macrophages containing minocycline [91] or the drug accumulated in the skin. [92] In systemic reactions, it is thought that minocycline acts as a super-antigen. [93] …”
