OBJECTIVE: Mitochondrial dysfunction and energy metabolism impairment are key components in the pathophysiology of bipolar disorder (BD) and may involve a shift from aerobic to anaerobic metabolism. Measurement of brain lactate in vivo using proton magnetic resonance spectroscopy (H-MRS) represents an important tool to evaluate mitochondrial and metabolic dysfunction during mood episodes, as well as to monitor treatment response. To date, very few studies have quantified brain lactate in BD...

REVIEW
Michael Gitlin
Despite its virtually universal acceptance as the gold standard in treating bipolar disorder, prescription rates for lithium have been decreasing recently. Although this observation is multifactorial, one obvious potential contributor is the side effect and toxicity burden associated with lithium. Additionally, side effect concerns assuredly play some role in lithium nonadherence. This paper summarizes the knowledge base on side effects and toxicity and suggests optimal management of these problems. Thirst and excessive urination, nausea and diarrhea and tremor are rather common side effects that are typically no more than annoying even though they are rather prevalent...

The effect of sodium as a co-dopant on the thermoluminescence (TL) properties of copper-doped zinc lithium borate (ZLB: Cu) subjected to Co-60 gamma radiation is reported in this study. TL intensity is enhanced with the introduction of sodium in ZLB: Cu. The obtained glow curve is simple with a single peak. The annealing procedure and the best heating rate for the proposed thermoluminescent dosimeter (TLD) are established, and the phosphor is reusable. The TL response within the dose range of 0.5-1000Gy is investigated...

OBJECTIVES: The putative neuroprotective effects of lithium treatment rely on the fact that it modulates several homeostatic mechanisms involved in the neurotrophic response, autophagy, oxidative stress, inflammation, and mitochondrial function. Lithium is a well-established therapeutic option for the acute and long-term management of bipolar disorder and major depression. The aim of this study was to evaluate the effects of subtherapeutic and therapeutic concentrations of chronic lithium treatment on brain-derived neurotrophic factor (BDNF) synthesis and secretion...

INTRODUCTION: Adolescence is a unique phase of the human developmental process. In adolescents, psychotropic medications may have different efficacy and tolerance profiles compared to those at other stages of the lifespan. Mood stabilizers are a complex pharmacological category including lithium, some anticonvulsants, and some second generation antipsychotics. Focusing on this class of pharmacological agents, we aim to answer the following questions: in which indications and according to which modalities should mood stabilizers be prescribed during adolescence? METHODS: Information was sought from the websites of the French Haute Autorité de santé (HAS) and Agence nationale de sécurité du médicament et des produits de santé (ANSM), the American Food and Drug Administration (FDA) and the British National Institute for Health and Clinical Excellence (NICE)...

BACKGROUND: HIV-associated neurocognitive disorder (HAND) remains highly prevalent despite effective anti-retroviral therapy (ART). A number of adjunctive pharmacotherapies for HAND have been studied with disappointing results, but preliminary data suggest that lithium may provide clinical benefit. In addition, the low cost of lithium would facilitate access in low- and middle-income countries which carry the greatest burden of HIV. METHODS: Our objective was to evaluate the 24-week efficacy and safety of lithium in patients with moderate to severe HAND...

BACKGROUND: Mood stabilizers like lithium and anticonvulsants are used in bipolar and related psychotic disorders. There is a lack of knowledge of the relationship of these medications and cognition in the psychosis spectrum. We studied the association between serum concentration of mood stabilizers and cognitive performance in a well-characterized sample of bipolar and schizophrenia spectrum disorders. METHODS: Serum concentrations of valproate, lamotrigine, and lithium were analyzed for associations to performance on neuropsychological tests in six cognitive domains in individuals with bipolar disorder (n = 167) and in a combined sample of individuals with bipolar or schizophrenia spectrum disorders (n = 217)...

INTRODUCTION: The risk of suicide is determined by the interplay of several interrelated factors from which psychiatric (especially affective) disorders are the most powerful predictors. Lithium, a mood stabilizer (which is also used to augment the efficacy of antidepressant therapy) has a well-established antisuicidal effect. In the last decades several studies investigated whether there is an association between the amount of lithium in tap water and suicide risk in the population. METHODS: A PubMed search was conducted to identify papers investigated the association between lithium levels in drinking water and suicide risk of the population...

Treatment resistance to the antidepressive pharmacotherapy represents one of the most important clinical challenges in the pharmacological management of unipolar depression. In this review, we aimed to summarise the evidence for various pharmacological treatment options in therapy-resistant unipolar depression derived from clinical trials, systematic reviews, meta-analyses and treatment guidelines. The first measure in case of insufficient response to the initial antidepressant monotherapy contains the debarment of 'pseudo-resistance', potentially caused by inadequate dose and treatment duration of the antidepressant, insufficient plasma levels, non-compliance of the patient regarding medication intake or relevant psychiatric and/or somatic comorbidities...

Malva sylvestris has recently attracted special attention due to its potential activities in many chronic disorders. We aimed to assess the beneficial effects of Malva sylvestris extract against lithium carbonate induced renal damage in male Wistar rats. For this purpose, Malva sylvestris extract at a dose of 0.2g/kg was orally administrated, followed by 25mg/kg of lithium carbonate (intraperitoneal injection) for 30 days. Malva sylvestris extract was proved to contain large amounts of K(+), Na(+), Ca(++) and the existence of phenolic acids and flavonoids shown by the obtained HPLC-based analysis...

Pyramidal neuron loss in the hippocampal CA1 region is a very early hallmark of Alzheimer disease (AD). Lithium might be a therapeutic strategy for AD due to its neuroprotective and neurotrophic properties. This study used modern stereological techniques to investigate possible CA1 pyramidal neuron loss in 11-month-old triple transgenic AD (3xTg-AD) mice, and also the effects of therapeutic and subtherapeutic lithium doses on the number and density of CA1 pyramidal neurons and volume of CA1 pyramidal layer in 3xTg-AD and wild-type mice treated from 3 to 11 months of age...

Click chemistries have been investigated for use in numerous biomaterials applications, including drug delivery, tissue engineering, and cell culture. In particular, light-mediated click reactions, such as photoinitiated thiol-ene and thiol-yne reactions, afford spatiotemporal control over material properties and allow the design of systems with a high degree of user-directed property control. Fabrication and modification of hydrogel-based biomaterials using the precision afforded by light and the versatility offered by these thiol-X photoclick chemistries are of growing interest, particularly for the culture of cells within well-defined, biomimetic microenvironments...

Dextromethorphan (DM) may have ketamine-like rapid-acting, treatment-resistant, and conventional antidepressant effects.(1,2) This reports our initial experience with DM in unipolar Major Depressive Disorder (MDD). A patient with treatment-resistant MDD (failing adequate trials of citalopram and vortioxetine) with loss of antidepressant response (to fluoxetine and bupropion) twice experienced a rapid-acting antidepressant effect within 48 hours of DM administration and lasting 7 days, sustained up to 20 days with daily administration, then gradually developing labile loss of antidepressant response over the ensuing 7 days...

Nephrogenic diabetes insipidus (NDI) is caused by impairment of vasopressin (VP) receptor type 2 signaling. Because potential therapies for NDI that target the canonical VP/cAMP/protein kinase A pathway have so far proven ineffective, alternative strategies for modulating aquaporin 2 (AQP2) trafficking have been sought. Successful identification of compounds by our high-throughput chemical screening assay prompted us to determine whether EGF receptor (EGFR) inhibitors stimulate AQP2 trafficking and reduce urine output...

Lithium Chloride (LiCl) has been used as a canonical Wnt pathway activator due to its ability to inhibit a glycogen synthase kinase-3. The aim of the present study was to investigate the effect of LiCl on cell proliferation and osteogenic differentiation in stem cells isolated from human exfoliated deciduous teeth (SHEDs). SHEDs were isolated and cultured in media supplemented with LiCl at 5, 10, or 20mM. The results demonstrated that LiCl significantly decreased SHEDs colony forming unit ability in a dose dependent manner...
