[Chloroquine keratopathy as an example of drug-induced phospholipidosis (contribution to the pathogenesis of cornea verticillata) (author's transl)].

Chronic treatment with certain drugs induces morphological alterations in the eye which are histologically and electron microscopically identical with those found in hereditary lipidoses (cornea verticillata, e.g. in M. Fabry). Hereditary storage diseases are the consequence of enzyme defects, the mechanism underlying the side effect of certain drugs, however, is quite different. "Amphiphilic" drugs from completely different pharmacological groups, like chloroquine, amiodarone, chlorpromazine form complexes with cellular phospholipids which cannot be metabolised by lysosomal phospholipases. Thus in all tissues with high phospholipid content or turnover typical intracellular deposites with lamellary or crystalloid structure may occur (myelin figures). Such deposites were observed in different parts of the eye and are known e.g. from the cornea as "cornea verticillata".

Drug-induced phospholipidosis. II. Alterations in the phospholipid pattern of organs from mice, rats and guinea-pigs after chronic treatment with chlorphentermine.

In three species chronic treatment with the anorectic drug chlorphentermine causes a profound alteration of the phospholipid/lipid metabolism in the organism, resulting in an increase of the fractions of phospholipids and lipids, e.g. in lungs, livers and adrenals. The results are interpreted as drug-induced generalized phospholipidosis, which is caused by amphiphilic drugs, like chlorphentermine and others. Its extent depends on several factors, like content, pattern and turnover rate of phospholipids in different organs, and on the species.
