Gastrointestinal Transit and Motility in Renal Transplant Recipients

January 23, 2013 updated by: Maria do Carmo Borges, Universidade Estadual de Ciências da Saúde de Alagoas

Non-invasive Assessment of Gastrointestinal Transit and Motility in Renal Transplant Recipients Employing a Biomagnetic Technique

Gastrointestinal (GI) complications after renal transplantation are commonly reported as side effects of immunosuppressive agents. Despite this, motility disorders have been scantily studied. Alternating Current Biosusceptometry (ACB) are biomagnetic sensors designed for a wide range of applications. In clinical practice, their non-invasive and radiation free features provide an excellent approach for monitoring of GI transit as alternative to scintigraphy and breath tests. The aim of this study is to examine GI transit and motility of solids in stable renal transplant recipients to determine the potential influence of immunosuppressive therapy on gastrointestinal parameters.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
January 1, 2011

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Anticipated)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
