Trial summary

Lithium therapy is cornerstone in therapy of bipolar disorders. A well known side-effect of lithium therapy is a urinary concentration defect which manifests in it's most severe form as nephrogenic diabetes insipidus. Read more about this study

About this study

Lithium therapy is cornerstone in therapy of bipolar disorders. A well known side-effect of lithium therapy is a urinary concentration defect which manifests in it's most severe form as nephrogenic diabetes insipidus. The development of urinary concentration defects and its progression to nephrogenic diabetes insipidus in the population of lithium treated patients is unknown and therefore this study aims to evaluate the decline of urinary concentration defects in a Dutch population of lithium treated patients. In this prospective cohort study, 51 participants treated with lithium at Canisius Wilhelmina Hospital, Nijmegen and included in the previous study in 2012 will be approached to undergo a follow-up dDAVP-test.

Being tested
Deamino Arginine Vasopressin (dDAVP)

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Deamino Arginine Vasopressin (dDAVP)Diagnostic test

    After voiding, 40 μg 1-desamino-8-D arginine vasopressin (dDAVP) will be administered intranasally. Throughout the day, urine volume and maximal renal concentrating ability will be determined by measuring osmolality in urine collected at 4 and 6 hours after administration of dDAVP. In addition, water intake, body weight, blood pressure and heart rate will be determined at baseline and 6 hours after administration of dDAVP.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Decline renal concentration ability

    To explore the decline in renal concentration ability (RCA) in a Dutch population of lithium treated patient. The primary endpoint is the percentual change in maximal urine osmolality.

    Measured: 10 years

Secondary outcomes (4)
  1. Relation between changes in kidney function and renal concentration ability

    To determine the correlation between changes in kidney function and renal concentration ability

    Measured: 10 years

  2. Relation between history of lithium-use and renal concentration ability

    To determine the relationship between renal concentration ability and clinical parameters (duration of lithium therapy, plasma lithium concentration, baseline plasma creatinine, sodium and potassium concentration and baseline urinary osmolality) of lithium treated patients.

    Measured: 10 years

  3. Chronic kidney disease

    To determine the number of patients with chronic kidney disease at follow-up.

    Measured: 10 years

  4. Decline in kidney-function

    To explore the decline in kidneyfunction (expressed as eGFR, estimated by the CKD-EPI equation).

    Measured: 10 years

Questions about this trial

What is this clinical trial studying?

An observational study of Lithium Toxicities and Bipolar Disorder, run by Radboud University Medical Center at 1 site in Netherlands.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 1 Apr 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact M.J. van der Aa ((073) 553 30 71, merel.vanderaa@radboudumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Decline renal concentration ability (time frame: 10 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Apr 2022.
