ObjectiveLithium users are offered routine renal monitoring but few studies have quantified the risk to renal health. The aim of this study was to assess the association between use of lithium carbonate and incidence of renal failure in patients with bipolar disorder.MethodsThis was a retrospective cohort study using the General Practice Research Database (GPRD) and a nested validation study of lithium exposure and renal failure. A cohort of 6360 participants aged over 18 years had a first recorded diagnosis of bipolar disorder between January 1, 1990 and December 31, 2007. Data were examined from electronic primary care records from 418 general practices across the UK. The primary outcome was the hazard ratio for renal failure in participants exposed to lithium carbonate as compared with non-users of lithium, adjusting for age, gender, co-morbidities, and poly-pharmacy.ResultsEver use of lithium was associated with a hazard ratio for renal failure of 2.5 (95% confidence interval 1.6 to 4.0) adjusted for known renal risk factors. Absolute risk was age dependent, with patients of 50 years or older at particular risk of renal failure: Number Needed to Harm (NNH) was 44 (21 to 150).ConclusionsLithium is associated with an increased risk of renal failure, particularly among the older age group. The absolute risk of renal failure associated with lithium use remains small.
Lithium use is associated with renal disorder and renal failure; this article offers guidance on monitoring, drug interactions, and when to consider stopping the drug
SummaryLithium is one of the most effective psychotropic drugs we have, but it is
underused because of its low therapeutic index, the need for regular blood
tests and perceptions about its adverse effects, including renal problems.
The last include urinary concentration deficits and diabetes insipidus,
chronic kidney disease (including renal failure), nephrotic syndrome,
hypercalcaemia, hyperparathyroidism and distal tubular acidosis. This
article reviews these adverse effects with special emphasis on their
management.
This integrated care pathway (ICP) is evidence of true multidisciplinary working resulting in mutually beneficial outcomes for both the acute and mental health trusts.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
