By continuing to browse Thus, even if not considered the main cause, NDI or substantial polyuria had been present in 16% of all hypernatraemia episodes. Hypernatraemia can develop into a serious or even life-threatening condition, if not treated quickly and appropriately.The aims of this study were (1) to determine the frequency of hypernatraemia episodes, (2) to assess the potential association with past and present lithium exposure and (3) to evaluate the fatality rate of hypernatraemia episodes.We collected the data as part of a retrospective cohort study (LiSIE) into the side effects and effects of lithium treatment as compared with other mood stabilizers for the maintenance treatment of affective disorders.

The… AQP2 mutations explain autosomal recessive and dominant NDI. A lack of AQP2 exocytosis (dotted lines) prevent the AVP-mediated water reabsorption in the collecting duct principal cells.These AQP2 mutants have a dominant effect over the wtAQP2 subunit and are responsible for AQP2 missorting.

Patients treated with lithium should be educated about diabetes insipidus, the risk of hypernatraemia and the importance of adequate fluid intake.Björn Forssén declares that there is no conflict of interest.Ursula Werneke has received funding for educational activities on behalf of Norrbotten Region (Masterclass Psychiatry Programme 2014–2018 and EAPM 2016, Luleå, Sweden): Astra Zeneca, Eli Lilly, Janssen, Novartis, Otsuka/Lundbeck, Servier, Shire and Sunovion.

In the kidney, AVP elicits a number of cellular responses, which converge on increasing the osmotic reabsorption of water in the collecting duct.

His rheumatologist thinks that it may be due to the thiazide so he was switched to amiloride.

The affected subject, being incapable of concentrating the urine, presents marked polyuria and compensatory polydipsia and is constantly at risk of severe dehydration.

Nephrogenic diabetes insipidus can be either acquired or hereditary. Antidepressants on the other hand, for example, selective serotonin reuptake inhibitors (SSRI) and tricyclic antidepressants (TCA), may decrease the risk of hypernatraemia through inappropriately increased vasopressin secretion (SIADH).In our study, infections and harmful use of substances including alcohol were the most common causes of hypernatraemia.

Clinicians should remain vigilant, have a low threshold for checking sodium concentrations and consider even risk factors for hypernatraemia beyond lithium.Lithium remains the first-line maintenance treatment for bipolar affective disorder (BPAD).Lithium is associated with an increased risk of loss of renal function.In the context of polyuria associated fluid imbalances and NDI, the risk of hypernatraemia may increase. Here, we considered both confirmed and suspected NDI. This ties in with our previous study of 91 episodes of severe lithium intoxications in the same cohort, in which only one patient was found to have a high sodium concentration.Recognising hypernatraemia early is important because it carries substantial mortality. The polyuria can be lowered with a low-salt (sodium), low-
