Continuation of lithium after a diagnosis of chronic kidney disease

Research output: Contribution to journalJournal articleResearchpeer-review

OBJECTIVE: To investigate whether continued lithium or anticonvulsant treatment after a first diagnosis of chronic kidney disease (CKD) was associated with progression to irreversible end-stage kidney disease.

METHODS: Nationwide cohort study including all individuals in Denmark in a period from 1995 to 2012 with a diagnosis of CKD and (i) a history of lithium treatment (N = 754, among whom 238 patients had a diagnosis of bipolar disorder) or (ii) a history of anticonvulsant treatment (N = 5.004, among whom 199 patients had a diagnosis of bipolar disorder). End-stage CKD was defined as chronic dialysis or renal transplantation.

RESULTS: Continuing lithium (HR = 0.58 (95% CI: 0.37-0.90) and continuing anticonvulsants (HR = 0.53 (95% CI: 0.44-0.64) were associated with decreased rates of end-stage CKD. In the subcohorts of patients with a diagnosis of bipolar disorder, continuing lithium was associated with decreased end-stage CKD (HR = 0.40 (95% CI: 0.17-0.98), whereas continuing anticonvulsants was not (HR = 0.70 (95% CI: 0.21-2.37). There were no interactions of continuing lithium and anticonvulsants.

CONCLUSION: After an initial diagnosis of CKD, patients who are selected by their physicians to continue lithium treatment may not necessarily have an increased risk of developing end-stage CKD. Shifting to an anticonvulsant per se may not be associated with an advantage; however, this requires further investigation.
