Long-term amodiaquine hydrochloride use caused drug-induced phospholipidosis, leading to ocular and skin changes. While some abnormalities improved, retinal function remained impaired.

Area of Science:

Ophthalmology
Toxicology
Cell Biology

Background:

Amodiaquine hydrochloride is an antimalarial drug.
Drug-induced phospholipidosis (DIPL) is a condition where drugs interfere with cellular lipid metabolism, leading to phospholipid accumulation.

Observation:

A 34-year-old man developed conjunctival, corneal, and skin changes after ingesting over 250g of amodiaquine hydrochloride for pain relief.
Ultrastructural analysis of biopsy specimens revealed intralysosomal inclusions in various ocular and skin cells.

Findings:

The patient's clinical and ultrastructural abnormalities showed improvement over a two-year follow-up.
Persistent abnormalities in retinal function tests were noted despite clinical improvement.

Implications:
