Abstract
Bacterial endotoxin lipopolysaccharide (LPS)-induced inflammatory response and ferroptosis play an important role in urinary tract infections. Tolterodine has been used as a urinary tract antispasmodic and anticholinergic agent. However, the effects of Tolterodine against LPS-induced insults in human bladder epithelial cells (hBECs) have not been reported before. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide and lactate dehydrogenase release assays to determine the cell viability, reactive oxygen species (ROS) and malondialdehyde level detection were used to determine the level of oxidative stress, enzyme-linked immunosorbent assay and Western blot analysis were used to detect the protein level. In the current study, we found that Tolterodine ameliorated LPS-induced production of ROS and lipid oxidation in hBECs. Interestingly, Tolterodine inhibited the production of interleukin 6, interleukin-1β, and tumor necrosis factor α. Also, Tolterodine reduced the levels of Fe2+ and suppressed ferroptosis by reducing the levels of glutathione peroxidase 4, prostaglandin-endoperoxide synthase 2, and acyl-CoA synthetase long-chain family member 4 in LPS-challenged bladder epithelial cells. Mechanistically, it was shown that Tolterodine restored the nuclear factor E2-related factor 2 (Nrf2)/nuclear factor-κB signaling. Importantly, inhibition of Nrf2 with its specific inhibitor ML385 abolished the protective effects of Tolterodine in the inflammatory response and ferroptosis, suggesting that the effects of Tolterodine are mediated by Nrf2. Based on these findings, we conclude that Tolterodine might serve as a promising agent for the treatment of LPS-induced bladder inflammation.

Schofield E, Taylor N, Drake MJ. The association of lower urinary tract symptoms with schizophrenia and its treatments: A narrative review. Neurourol Urodyn 2024; 43:114-125. [PMID: 37916430 DOI: 10.1002/nau.25320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2023] [Revised: 09/14/2023] [Accepted: 10/22/2023] [Indexed: 11/03/2023]
Abstract
BACKGROUND A higher incidence of lower urinary tract symptoms (LUTS) in people with schizophrenia compared to the general population is often suggested. However, it is not clear whether this is a genuine association, and whether it is a direct result of schizophrenia itself, or a side-effect of certain antipsychotics. METHODS We undertook a narrative review evaluating how the published literature reports the relationship between LUTS and schizophrenia and its treatments. We searched Embase, Ovid Emcare, and Ovid MEDLINE(R) ALL to August 2022, limited to the English language. We selected the following search terms: schizophrenia, schizophrenic, LUTS, overactive bladder, urinary urgency, urinary incontinence, overactive bladder, enuresis, nocturnal enuresis, and voiding dysregulation. We identified seven domains for assessment in advance of commencing the review. These were the categorization, description, and treatment status of schizophrenia; evaluation of LUTS; categorization of LUTS confounders; recapturing of the disease states of both schizophrenia and LUTS after therapies; assessment of the association between LUTS and schizophrenia and/or antipsychotics. RESULTS The association between LUTS and schizophrenia was poorly described. The evidence was low quality and focused predominantly on urinary incontinence as an antipsychotic side effect, neglecting other LUTS. The status of schizophrenia was often incompletely characterized, and no papers made use of a bladder diary or LUTS-specific questionnaires to assess symptoms. No papers collected information about LUTS in patients not on antipsychotics, nor did any thoroughly evaluate the influence of confounding variables. Despite the tendency of symptoms and severity of both conditions to fluctuate over time, no studies fully assessed the status of both schizophrenia and LUTS at baseline, therapy initiation, and follow-up. CONCLUSIONS It is not possible to state whether there is an association between LUTS and schizophrenia or its treatments. This review highlights the need to improve research and clinical management of the urinary tract in schizophrenia, with meticulously designed longitudinal studies.

Grover S, Kathiravan S. Clozapine research from India: A systematic review. Asian J Psychiatr 2023; 79:103353. [PMID: 36493690 DOI: 10.1016/j.ajp.2022.103353] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/02/2022] [Revised: 11/09/2022] [Accepted: 11/20/2022] [Indexed: 11/27/2022]
Abstract
BACKGROUND Although clozapine is much researched in western literature, a review on Indian research on clozapine published in 2010 reported limited data and need for further research in this area. AIM We aimed to conduct a systematic review of research on clozapine from India from 2010 to mid-2022 and also compare the same with research output before 2010. METHODOLOGY A systematic various search engines, i.e., PUBMED, Medknow, Hinari and Google Scholar was done using the key words clozapine and India. Published articles with clozapine in the title and having an author from India, published during 2010 to July 2022 were included. RESULTS Initial Internet and hand searches yielded 280 articles, out of which 126 articles were excluded due to various reasons and 154 articles, were included for the review. This included 84 case reports, 49 original articles, 11 review articles and 10 letters to the editor as comments. We found an increase in the number of publications during the period of 2010-2022 compared to 1997-2009 in all types of publications. Over the years a significant proportion of the articles focused on various side effects of clozapine, factors associated with response and non-response to clozapine and evaluation of outcomes other than efficacy/effectiveness. However, all the studies were limited to a single centre with no multicentric studies on clozapine. CONCLUSION Over the last 12 years or so, there is increase in the number of publications on clozapine. However, there is lack of multicentric studies.

CNS Spectr 2022; 28:1-12.

Abstract
BACKGROUND Clozapine is the most effective medication for treatment-refractory schizophrenia but is associated with significant adverse drug reactions, including nocturnal enuresis and urinary incontinence. This side effect can be burdensome and lead to medication nonadherence and psychotic relapse. Evidence to guide treatment of clozapine-induced nocturnal enuresis and urinary incontinence is sparse. We therefore aimed to synthesize the evidence base to guide management for clinicians, patients, and their carers. METHODS We systematically searched PubMed, Embase, PsycInfo, CINAHL, and the Cochrane Trial Registry databases from inception to May 2021 for publications on management of clozapine-induced nocturnal enuresis and urinary incontinence using a PROSPERO preregistered search strategy. RESULTS We identified 22 case reports and case series describing 74 patients. Interventions included clozapine dose reduction, nonpharmacological treatment, and pharmacological treatments. Among pharmacological treatments, desmopressin, oxybutynin, trihexyphenidyl, tolterodine, imipramine, amitriptyline, ephedrine, pseudoephedrine, aripiprazole, and verapamil were associated with complete resolution of nocturnal enuresis and urinary incontinence. Balancing evidence for effectiveness against risk of adverse effects, we developed a management framework for clozapine-induced nocturnal enuresis and urinary incontinence. CONCLUSIONS Following assessment of urological, psychiatric, pharmacological, and common comorbid medical issues, first-line treatments should be nonpharmacological, including bathroom alarms, voiding before bedtime, and nocturnal fluid restriction. If these interventions do not provide adequate relief, aripiprazole should be trialed. Desmopressin may be considered for severe refractory cases, but monitoring for hyponatremia is essential.
