| Pathologie, précisions | Cystinosis: The disease is caused by mutations in the CTNS gene coding for cystinosin, a lysosomal carrier protein. The lysosomal cystine accumulation leads to cellular dysfunction in many organs. The first symptoms start at about 6 months of age with anorexia, polyuria, and failure to thrive, secondary to a Fanconi proximal renal tubulopathy. In the absence of specific therapy, end stage renal disease occurs between 6 and 12 years of age. Survival beyond this age is associated with the development of extra-renal complications in eyes, thyroid, gonads, endocrine pancreas, muscle and central nervous system |

| Informations complémentaires concernant la constitution de l'échantillon |
Paediatric and adult patients will be mainly recruited through the network of reference, competence and recognised expert centres of rare kidney diseases. For some prevalent adult patients, recruitment will be through sites identified as in charge of regular care of cystinosis patients. During regular care follow-up visit for prevalent patient and during their first regular care visit (post-diagnosis) for incident patient, investigator will inform patients meeting the inclusion criteria about the RaDiCo-ECYSCO cohort and invite them to participate.
All patients meeting criteria for inclusion and non-inclusion and willing to participate will be informed of the terms of the study during their consultation. Informed consent form and patient information sheet will be provided and explained by the investigator. Patients will be given as much time as necessary to evaluate their participation to the study. Participation in another study is not an exclusion criterion for this study as this is a follow-up of cohort type study. Also, participation in this study do not prevent participation in another study. |
| Objectif de la base de données | |
| Objectif principal |
The primary objective of the RaDiCo-ECYSCO cohort is to understand the natural history and major long-term manifestations and outcomes of cystinosis in paediatric and adult cases.
Secondary Objectives are to: • Evaluate the impact of disease and treatments on patients’ quality of life • Evaluate the effect of treatment on the complications • appraise the long-term safety of treatment and compliance Information Technology Objectives are to: • Develop and diffuse an electronic tool of data collection from various sources linked to a database integrating a system of management and follow-up of data-management allowing collection of data for cystinosis paediatric and adult patients. • Include data generated by patients and, where relevant, their parents and or carers. • Expand the cohort to cover a broader European population. • Promote the use of the RaDiCo-ECYSCO eCRF for mutualisation and harmonisation of data for cystinosis paediatric and adult patients within the expert sites. Improvement of standard care objectives are to: • Develop comprehensive evidence based guidelines for treatments as well as for follow-up of patients who will switch from paediatric to adult status, • Propose a system of audit against the guidelines ensuring overall care is of the highest standard as well as identifying areas of concern for actions. |
| Critères d'inclusion |
The RaDiCo-ECYSCO Cohort inclusion criteria are the following:
• Confirmed diagnosis of cystinosis (based on cystine dosage and/or presence of crystals at eye examination and/or molecular diagnosis) • Signed informed consent Non-inclusion Criteria • Patients not able to give their informed consent. No other non-inclusion criteria (patients with associated disease should be enrolled) |

It will include all retrospective data previously collected in the CEMARA database (CNIL authorisation number: 1187326 for France; regulatory requirements for Belgium and Italy were the responsibility of the participating local site) and new data from follow-up visit of prevalent patients as well as from incident patients (new inclusions). |

| Données biologiques, précisions | Laboratory analyses: Leucocyte cystine level (expressed as nanomoles of half-cystine per milligram of protein, normal <0.15) is measured before cysteamine administration, and determined and collected at least once a year. As the WBC cystine assay is complex and highly variable between laboratories, plasma cysteamine concentration will also be collected. Sites are encouraged to record all annual additional laboratory analyses, as exploratory objective. Other laboratory analyses are performed according to current care of patients (creatininemia, kaliemia, glycaemia, Thyroid Stimulating Hormone…). |
