Cystinosis is a multisystemic autosomal recessive disorder characterized by an
intra-lysosomal accumulation of cystine. It is due to a defect of cystine
transport through the membrane of the lysosome. The classical infantile form is
characterized by a proximal tubulopathy, corneal cystine crystals and progressive
renal failure, leading to end stage renal disease before 20 years of age in 90%
of cases in historical cohorts. It is the most common cause of Fanconi syndrome
in children. Due to recent progress in renal transplantation and to the specific
treatment with cysteamine, patients survival improved significantly in the last
years and adult nephrologists take care of such patients. However, disease
evolution is characterized by other complications: endocrinological
(hypothyroidism, diabetes, male hypogonadism), neuromuscular and of the central
nervous system. Cysteamine delays the onset of these complications. A
multidisciplinary team should take care of these patients, even if the
nephrologist remains in first line. Apart from infantile form, there is a
juvenile form, with a later onset, and an adult form, which may be only ocular,
although renal involvement may be associated. The aim of this revue is to
summarize actual knowledge of the disease to provide guidance to adult
nephrologist to take care of his patients.
