What the trial is, and whether it could suit you

Cystinosis is an inherited disease resulting in poor growth and kidney failure. There is no known cure for cystinosis, although kidney transplantation may help the renal failure and prolong survival. Both the kidney damage and growth failure are thought to be due to the accumulation of the amino acid cystine within the cells of the body. The cystine storage later damages other organs besides the kidneys, including the thyroid gland, pancreas, eyes, and muscle. The drug cysteamine (Cystagon; ProCysBi) is an oral medication given to patients with cystinosis prior to kidney transplantation. The drug works by reducing the level of cystine in the white blood cells and muscle tissue. The drug may also decrease levels of cystine in the kidneys and other tissues. This study has several goals: 1. Long-term surveillance of cysteamine treated patients. 2. Detection of new non-kidney complication

* INCLUSION CRITERIA: Diagnosis of cystinosis, whether classical or one of the variants with later onset or no renal complications.

EXCLUSION CRITERIA: Inability to travel to the NIH. Age less than one week. Nonviable neonates and neonates of uncertain viability will be excluded.
