Infants with the disorder are extremely fussy babies and initially show failure to thrive and later failure to grow normally. [avrobio.com]
The disease results in deposition of crystals throughout the body; if untreated, it leads to failure to thrive, profound metabolic imbalance, early end-stage renal disease, thyroid failure, and multiorgan dysfunction. [nejm.org]
Signs and symptoms of nephropathic infantile cystinosis include the following: Multiorgan involvement: May be mild to severe Polyuria, polydipsia, dehydration, vomiting, metabolic acidosis Hypophosphatemic rickets Constipation Failure to thrive, poor/ [emedicine.medscape.com]

Cysteamine treatment does not cure Fanconi syndrome, but prevents or delays progression to ESRD [ 11 ]. This treatment prevents the development of multiple extra-renal complications [ 12 ]. [link.springer.com]
Immediate-release cysteamine is an effective treatment for slowing some of the consequences of cystinosis, but Langman said many factors make it hard for patients to stick with their treatment. [raredr.com]

Epidemiology There are three main forms of the disease which are described as infantile, juvenile, and adult cystinosis. [eyewiki.aao.org]
The two novel mutations in our patient also give some insight into the genetic epidemiology of cystinosis. Cysteamine is a specific treatment for cystinosis. [link.springer.com]
Pathophysiology
Although the pathophysiology of this rare complication is unclear, in the absence of other aetiologies the likely cause is the patient's poorly controlled cystinosis. [link.springer.com]

Prevention
Cysteamine treatment does not cure Fanconi syndrome, but prevents or delays progression to ESRD [ 11 ]. This treatment prevents the development of multiple extra-renal complications [ 12 ]. [link.springer.com]
Your doctor may also recommend vitamin D and phosphorus supplements to prevent rickets. [healthline.com]
Cysteamine has proven effective in delaying or preventing renal failure. Cysteamine also improves growth of children with Cystinosis. [cystinosis.org]
The findings, published recently by the journal EMBO Molecular Medicine, could eventually lead to new drug treatments for reducing or preventing the onset of renal failure in patients. [scripps.edu]
However, treatment with cysteamine must be continued to delay or even prevent the occurrence of extra-renal complications. [sjkdt.org]
