Methemoglobinemia as a biomarker of dapsone-induced mania severity

J Affect Disord. 2019 Jul 1:254:122-123. doi: 10.1016/j.jad.2018.12.123. Epub 2018 Dec 25.

Abstract

Background: The underlying mechanism involved in dapsone-induced mania remains unknown.

Methods: We report the case of a 54-year-old man with a dapsone-induced mania.

Results: The maximum of manic symptoms was correlated with the maximum of methemoglobinemia and mania decreased concomitantly with the methemoglobinemia level.

Limitations: This is a single case.

Conclusions: This case shows that dapsone-induced mania severity is correlated with methemoglobinemia level, leading for the first time to the hypothesis of a physiopathological mechanism by which dapsone could induce mania.

Keywords: Biomarker; Dapsone; Mania; Methemoglobinemia; Oxydative stress.
