Study summary

What the protocol is testing.

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.

Interventions

Treatment arms and agents.

DIAGNOSTIC_TEST

Deamino Arginine Vasopressin (dDAVP)

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.

Outcomes

What the study measures.

Primary outcomes

Decline renal concentration ability

Time frame · 10 years

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.

Secondary outcomes

Relation between changes in kidney function and renal concentration ability

Time frame · 10 years

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

Relation between history of lithium-use and renal concentration ability

Time frame · 10 years

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.

Chronic kidney disease

Time frame · 10 years

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

Decline in kidney-function

Time frame · 10 years

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