Abstract:
We present the first case of multiple fixed drug eruption caused by tranexamic acid, which was confirmed by the LTT. This case was difficult to diagnose because the drug-induced aseptic meningitis by loxoprofen was occurred simultaneously.
Insights
Multiple fixed drug eruptions caused by tranexamic acid were identified using the lymphocyte transformation test (LTT). Diagnosis was complicated by concurrent drug-induced aseptic meningitis from loxoprofen.
Area of Science:
- Pharmacology
- Dermatology
- Immunology
Background:
- Fixed drug eruption (FDE) is a specific type of adverse drug reaction.
- Tranexamic acid is increasingly used for various medical conditions.
- Drug-induced aseptic meningitis is a known neurological side effect of some medications.
Observation:
- A patient presented with recurrent, well-demarcated skin lesions consistent with FDE.
- The patient was also experiencing symptoms suggestive of aseptic meningitis.
- Loxoprofen was identified as a potential cause of aseptic meningitis.
Findings:
- The lymphocyte transformation test (LTT) confirmed tranexamic acid as the causative agent for the multiple fixed drug eruptions.
- This represents the first reported case of FDE specifically linked to tranexamic acid.
- The simultaneous occurrence of FDE and drug-induced aseptic meningitis presented a diagnostic challenge.
Implications:
- Highlights the potential for tranexamic acid to cause FDE, necessitating increased clinical awareness.
- Emphasizes the importance of considering multiple concurrent adverse drug reactions in complex cases.
- Suggests the utility of LTT in diagnosing FDE when drug causality is uncertain.
