Juvenile Cystinosis

Cystiis Late Onset Juvenile or Adolescent Nephropathic Type


Presentation

  • We report glomerular lesions in 2 siblings presenting a juvenile cystinosis.[ncbi.nlm.nih.gov]
  • Leading experts from Latin America, Africa, Near and Middle East, Indian Subcontinent, Far East, Oceania and Australia present their expert insights into specific conditions, as well as progress and challenges in the development of the specialty.[books.google.de]
Pathologist
  • MO is a renal pathologist who helped diagnosis the patient. SI supervised the study. All authors read and approved the final manuscript. Consent for publication The patient and his mother gave informed consent for the publication of data.[link.springer.com]
Failure to Thrive
  • Failure to thrive is generally noticed after approximately age six months; signs of renal tubular Fanconi syndrome (polyuria, polydipsia, dehydration, and acidosis) appear as early as age six months; corneal crystals can be present before age one year[ncbi.nlm.nih.gov]
  • Cystinosis may present with symptoms of polyuria, thirst, failure to thrive, growth retardation, vomiting, periods of dehydration, constipation and developmental delay.[jcdr.net]
  • 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]
  • Infants with the disorder are extremely fussy babies and initially show failure to thrive and later failure to grow normally.[avrobio.com]
  • Case Report A 3-year-old female child was referred to our institution for failure to thrive, polyuria, polydipsia, and salt craving.[indianjnephrol.org]
Vascular Disease
  • While unconventional, it seemed more acceptable to lay the book out under the relatively limited and broad headings which ophthalmologists use as indications for enucleation: "trauma", "tumour", "endophthalmitis", "vascular disease", etc.[books.google.com]

Treatment

  • 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]

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]
  • More than 2,000 disease genes have been identified in the last 20 years, providing important new insight into the pathophysiology of diseases in every field of medicine.[books.google.de]

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]
