Hyponatraemia is a well-established and potentially, a life-threatening adverse effect of selective serotonin receptor uptake inhibitors (SSRI). However, its occurrence secondary to syndrome of inappropriate antidiuretic hormone secretion (SIADH) with escitalopram, has been reported extremely sporadically. The reporting of such rare, but life-threatening adverse effects of escitalopram assumes immense significance in light of the fact that SSRIs presently form the mainstay of treatment of depressive disorders...

Abnormal activation of the Wnt/β-catenin signaling is implicated in the osteoarthritis (OA) pathology. We searched for a pre-approved drug that suppresses abnormally activated Wnt/β-catenin signaling and has a potency to reduce joint pathology in OA. We introduced the TOPFlash reporter plasmid into HCS-2/8 human chondrosarcoma cells to estimate the Wnt/β-catenin activity in the presence of 10 μM each compound in a panel of pre-approved drugs. We found that fluoxetine, an antidepressant in the class of selective serotonin reuptake inhibitors (SSRI), down-regulated Wnt/β-catenin signaling in human chondrosarcoma cells...

Selective serotonin reuptake inhibitors (SSRIs) are the most commonly used medications for mood and anxiety disorders, and adult neurogenesis in the dentate gyrus has been shown to be involved in the behavioral effects of SSRIs in mice. Studies have shown the varied effects of chronic treatment with SSRIs on adult neurogenesis. One such effect is the acceleration of neuronal maturation, which affects the functional integration of new neurons into existing neuronal circuitry. In this study, we labeled new neurons by using GFP-expressing retroviral vectors in mice and investigated the effect of an SSRI, fluoxetine, on these neurons at different time points after neuronal birth...

BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs) are the most common antidepressants used to preclude maternal pregnancy depression. There is a growing body of literature assessing the association of prenatal exposure to SSRIs with autism spectrum disorder (ASD). The present systematic review and meta-analysis reviewed the medical literature and pooled the results of the association of prenatal exposure to SSRIs with ASD. METHODS: Published investigations in English by June 2016 with keywords of selective serotonin reuptake inhibitors, SSRI, autism spectrum disorder, ASD, pregnancy, childhood, children, neurodevelopment were identified using databases PubMed and PMC, MEDLINE, EMBASE, SCOPUS, and Google Scholar...

Exposure to prenatal insults has been associated with an increased risk for neuropsychiatric disorders, including depression, but the mechanisms are still poorly understood. Persistent alterations of the HPA axis feedback mechanism as well as adult impaired neurogenesis are believed to play a relevant role in the etiology of depression. In addition, growing evidence points at epigenetic reprogramming as a key factor. We have previously shown that prenatal exposure to the synthetic glucocorticoid dexamethasone (DEX) impairs neurogenesis and leads to late onset of depression-like behavior that does not respond to the SSRI antidepressant fluoxetine (FLX)...

Early trauma and stress exposure during a critical period of life may increase the risk of major depressive disorder (MDD) and post-traumatic stress disorder (PTSD) in adulthood. The first-choice treatment for MDD and PTSD are selective serotonin reuptake inhibitor (SSRI) antidepressants. Unfortunately, half of MDD and PTSD patients show resistance to the therapeutic effects of these drugs and more efficient treatments are essential. Both MDD and PTSD patients present reduced levels of allopregnanolone (Allo), a potent endogenous positive allosteric modulator of GABA action at GABAA receptors which are normalized by SSRIs in treatment responders...

BACKGROUND: Dysfunction of the serotonergic (5-HTergic) system has been implicated in the cognitive and behavioural symptoms of Alzheimer's disease (AD). Accumulation of toxic amyloid-β (Aβ) species is a hallmark of AD and an instigator of pathology. Serotonin (5-HT) augmentation therapy by treatment with selective serotonin reuptake inhibitors (SSRIs) in patients with AD has had mixed success in improving cognitive function, whereas SSRI administration to mice with AD-like disease has been shown to reduce Aβ pathology...

Following spinal cord injury (SCI), reflexes become hyperexcitable, leading to debilitating muscle spasms and compromised motor function. Previous work has described adaptations in spinal systems that might underlie this hyperexcitability, including an increase in constitutively active 5-HT2C receptors in spinal motoneurons. That work, however, examined adaptations following complete transection SCI, whereas SCI in humans is usually anatomically and functionally incomplete. We therefore evaluated whether constitutive activity of 5-HT2C receptors contributes to reflex hyperexcitability in an incomplete compression model of SCI and to spasms in vitro and in vivo...

OBJECTIVE: Selective serotonin reuptake inhibitors (SSRIs) may aggravate anxiety and agitation during the first days of treatment but the frequency of such reactions remains unknown. METHOD: We analysed patient-level data from placebo-controlled trials of sertraline, paroxetine or citalopram in depressed adults. Somatic anxiety, psychic anxiety and psychomotor agitation as assessed using the Hamilton Depression Rating Scale (HDRS) were analysed in all trials (n = 8262); anxiety-related adverse events were analysed in trials investigating paroxetine and citalopram (n = 5712)...

OBJECTIVE: Major depressive disorder (MDD) can substantially worsen patient-reported quality of life (QOL) and functioning. Prior studies have examined the role of age in MDD by comparing depressive symptom severity or remission rates between younger and older adults. This study examines these outcomes before and after SSRI treatment. On the basis of prior research, we hypothesized that older adults would have worse treatment outcomes in QOL, functioning, and depressive symptom severity and that nonremitters would have worse outcomes...

YL-0919 has been identified as a novel dual 5-HT1A partial agonist and serotonin reuptake inhibitor. In the current study, we demonstrated that YL-0919 produced prominent antidepressant-like and anxiolytic-like effects in a chronic unpredictable stress (CUS) rat model. Male SD rats were exposed to CUS for 5 weeks; YL-0919 (1.25 and 2.5 mg/kg) or a positive control fluoxetine (Flx, 10 mg/kg) was orally administered daily. YL-0919 or Flx treatment significantly increased the sucrose preference rate, the locomotor activity in an open field test (OFT), the latency to feed in a novelty-suppressed feeding test (NSFT), and both the percentage of time spent in the open arms and the number of entries into the open arms in an elevated plus-maze test...

BACKGROUND AND OBJECTIVES: Few studies have reported the association of the use of selective serotonin reuptake inhibitors (SSRIs) with acute pancreatitis. We conducted a population-based case-control study to explore this relationship. METHODS: In this study, 4631 cases with first attack of acute pancreatitis and 4631 controls without acute pancreatitis were selected using a randomly sampled cohort of one million health insurance enrollees from 2000 to 2013. Both cases and controls were aged 20-84 years and were matched with sex, age, comorbidities, and index year of diagnosis of acute pancreatitis...

BACKGROUND: Generalised anxiety disorder (GAD) is common, causing unpleasant symptoms and impaired functioning. The National Institute for Health and Care Excellence (NICE) guidelines have established good evidence for low-intensity psychological interventions, but a significant number of patients will not respond and require more intensive step 3 interventions, recommended as either high-intensity cognitive behavioural therapy (CBT) or a pharmacological treatment such as sertraline. However, there are no head-to-head comparisons evaluating which is more clinically effective and cost-effective, and current guidelines suggest that treatment choice at step 3 is based mainly on patient preference...

The use of antidepressants in pregnant women is rising, with rates up to 7.5% in the United States. Selective serotonin reuptake inhibitors (SSRIs) are currently the most common antidepressant prescribed to pregnant women. The teratogenic effects of SSRI exposure are debated because of discrepancies in epidemiological studies. As an alternative to epidemiological and animal studies, human embryonic stem cell research (hESC) provides a human-based experimental model to examine the risks of prenatal SSRI exposure...

BACKGROUND&AIMS: Besides its critical role during liver regeneration, 5-HT has been found to act as a mitogenic factor in several neoplastic entities. Accordingly, we aimed to evaluate whether IP5-HT was associated with oncological outcome after liver resection and concomitantly evaluate its ability to serve as a therapeutic target to promote liver regeneration. METHODS: 96 patients undergoing liver resection for malignant liver tumors were prospectively included...

BACKGROUND: Many studies have reported that selective serotonin reuptake inhibitors (SSRI) are associated with an increased risk of bleeding. Mirtazapine and bupropion, which commonly lack serotonin reuptake inhibition, have been recommended as alternatives for patients who are at risk for bleeding. However, the evidence for these recommendations is insufficient. METHODS: We conducted a systematic search, systematic review, and meta-analysis to investigate an evidence-based approach for the bleeding risks of mirtazapine and bupropion...
