International (Pediatric) Peritoneal Biobank
NCT01893710 · View on ClinicalTrials.gov ↗
Study Summary
Within few years the peritoneal membrane of adult peritoneal dialysis (PD) patients undergoes substantial morphological transformation, including progressive fibrosis, vasculopathy and neoangiogenesis. Ultrafiltration capacity steadily declines and ultimately results in PD failure. In children, peritoneal biopsies demonstrating PD associated alterations have not yet been obtained. They, however, should be particularly informative, since secondary tissue and vascular pathology related to ageing or diabetes is absent. An international, prospective peritoneal membrane biopsy study in children on PD will therefore be performed. Biopsies will be obtained at time of PD catheter insertion, on occasion of intercurrent abdominal surgery (e.g. hernia repair, catheter exchange) and at time of renal transplantation. Quantitative histomorphometry and tissue protein expression analyses will be correlated with time integrated PD treatment modalities and functional characteristics as well as inflammatory and cardiovascular comorbidity surrogate parameter. Blood will be obtained during clinical routine sampling. Biopsies will be obtained during clinically indicated operations, without substantially increasing operation time and associated surgical risks. The detailed histomorphometry of the PD membrane will give additional information, potentially impacting on the individual PD regime. 3/2018: The analyses of the pediatric PD biopsy demonstrated early and major transformation of the peritoneal membrane with neutral pH low GDP fluids, and significant vasculopathy already in children with CKD stage 5, further progressing with PD. The underlying mechanisms are partly understood, only. In view of these major findings and the numerous open questions, collection of biosamples will be continued in children and also in adult PD patients. The following questions will be addressed: Molecular counterparts of peritoneal semi-permeability, solute and water transport (beyond AQP1), pathomechani

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT01893710
The ClinicalTrials.gov registry entry for NCT01893710 describes a study currently listed as recruiting. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 500 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Heidelberg University, which has 1 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Healthy appearing as the primary indexed condition, and to 1 intervention — of which biopsy sampling is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT01893710 reports 20 study locations spanning 5 distinct geographic areas — top geographies include Other, Alabama, Missouri. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
