Abstract
Abstract
In mammals, dormant primordial follicles represent the ovarian reserve throughout reproductive life. In vitro activation of dormant primordial follicles has been used to treat patients with premature ovarian insufficiency (POI). However, there remains a lack of effective strategies to stimulate follicle activation in vivo. In this study, we used an in vitro ovarian culture system and intraperitoneal injection to study the effect of lithium treatment on primordial follicle activation. Lithium increased the number of growing follicles in cultured mouse ovaries and promoted pre-granulosa cell proliferation. Furthermore, lithium significantly increased the levels of phosphorylated protein kinase B (Akt) and the number of oocytes with forkhead Box O3a (FOXO3a) nuclear export. Inhibition of the phosphatidylinositol 3 kinase (PI3K)/Akt pathway by LY294002 reversed lithium-promoted mouse primordial follicle activation. These results suggest that lithium promotes mouse primordial follicle activation by the PI3K/Akt signaling. Lithium also promoted primordial follicle activation and increased the levels of p-Akt in mouse ovaries in vivo and in human ovarian tissue cultured in vitro. Taken together, lithium promotes primordial follicle activation in mice and humans by the PI3K/Akt signaling. Lithium might be a potential oral drug for treating infertility in POI patients with residual dormant primordial follicles.

Clin Endocrinol (Oxf) 2021; 95:520-526. [PMID: 33978246 DOI: 10.1111/cen.14497] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/19/2021] [Revised: 04/23/2021] [Accepted: 04/30/2021] [Indexed: 01/01/2023]
Abstract
OBJECTIVE Diuretics are often implicated in hyponatraemia. While thiazides constitute one of the most common causes of hyponatraemia, data on loop diuretics and potassium-sparing agents are limited and partly conflicting. The objective of this investigation was to study the association between use of different types of non-thiazide diuretics and hospitalization due to hyponatraemia. DESIGN, PATIENTS AND MEASUREMENTS This was a register-based case-control study on the adult Swedish population. By linking national registers, patients hospitalized with a principal diagnosis of hyponatraemia (n = 11,213) from 1 October 2005 through 31 December 2014 were compared with matched controls (n = 44,801). Multivariable logistic regression, adjusted for multiple confounders, was used to analyse the association between use of diuretics and hyponatraemia. In addition, newly initiated use (≤90 days) and ongoing use were examined separately. RESULTS Adjusted odds ratios (aORs) (95% CI) were 0.61 (0.57-0.66) for the use of furosemide, 1.69 (1.54-1.86) for the use of amiloride and 1.96 (1.78-2.18) for the use of spironolactone and hospitalization due to hyponatraemia. For newly initiated therapy, aORs ranged from 1.23 (1.04-1.47) for furosemide to 3.55 (2.75-4.61) for spironolactone. The aORs for ongoing use were 0.52 (0.47-0.57) for furosemide, 1.62 (1.47-1.79) for amiloride and 1.75 (1.56-1.98) for spironolactone. CONCLUSIONS Ongoing use of furosemide was inversely correlated with hospitalization due to hyponatraemia, suggesting a protective effect. Consequently, if treatment with furosemide precedes the development of hyponatraemia by some time, other causes of hyponatraemia should be sought. Spironolactone and amiloride may both contribute to hyponatraemia; this effect is most prominent early in treatment.

[PMID: 34249136 PMCID: PMC8227445 DOI: 10.2174/1745017902117010026] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2020] [Revised: 02/28/2021] [Accepted: 03/09/2021] [Indexed: 11/24/2022]
Abstract
Background: Catatonia is a syndrome of altered motor behavior that is mostly associated with general medical, neurologic, mood and schizophrenia-spectrum disorders. The association of newly onset catatonic symptoms with hyponatremia has been rarely reported in the literature. Case Presentation: We present a rare case of a young female patient with schizophrenia, who presented with catatonic symptoms in the context of hyponatremia due to water intoxication. The symptoms were eliminated with the correction of hyponatremia. There are only a few reports of hyponatremia-associated catatonia in psychiatric and non-psychiatric patients. Sometimes, catatonic symptoms may co-occur with newly onset psychotic symptoms and confusion, suggesting delirium. In several cases, the catatonic symptoms responded to specific treatment with benzodiazepines or electroconvulsive therapy.
Conclusion:
Hyponatremia may induce catatonic symptoms in patients, regardless of underlying mental illness, but this phenomenon is even more relevant in patients with a psychotic or mood disorder, which may itself cause catatonic symptoms. It is important for clinicians not to attribute newly-onset catatonic symptoms to the underlying psychotic or mood disorder without measuring sodium serum levels. The measurement of sodium serum levels may guide treating psychiatrists to refer the patient for further investigation and appropriate treatment.

Eur J Clin Pharmacol 2021; 77:747-755. [PMID: 33215235 PMCID: PMC8032630 DOI: 10.1007/s00228-020-03006-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2020] [Accepted: 09/18/2020] [Indexed: 11/17/2022]
Abstract
PURPOSE Drug-induced hyponatremia is common, with medications from many drug-classes implicated. Lipid-lowering agents are among the most prescribed drugs. Limited evidence suggests an inverse association between statins and hyponatremia, while data on other lipid-lowering agents is absent. The objective of this investigation was to study the association between lipid-lowering drugs and hospitalization due to hyponatremia. METHODS This was a register-based case-control study of the general Swedish population. Those hospitalized with a main diagnosis of hyponatremia (n = 11,213) were compared with matched controls (n = 44,801). Multivariable logistic regression adjusting for co-medication, diseases, previous hospitalizations, and socioeconomic factors was used to explore the association between severe hyponatremia and the use of lipid-lowering drugs. RESULTS Unadjusted ORs (95% CI) for hospitalization due to hyponatremia were 1.28 (1.22-1.35) for statins, 1.09 (0.79-1.47) for ezetimibe, 1.38 (0.88-2.12) for fibrates, and 2.12 (1.31-3.35) for resins. After adjustment for confounding factors the adjusted odds ratios (95% CI) compared with controls were 0.69 (0.64-0.74) for statins, 0.60 (0.41-0.86) for ezetimibe, 0.87 (0.51-1.42) for fibrates, and 1.21 (0.69-2.06) for resins. CONCLUSIONS Use of statins and ezetimibe was inversely correlated with severe hyponatremia. Consequently, these drugs are unlikely culprits in patients with hyponatremia, and they appear safe to initiate in hyponatremic patients. A potential protective effect warrants further studies on how statins and other lipid-lowering drugs are linked to dysnatremias.
