Food Chem Toxicol 2024; 187:114637. [PMID: 38582345 DOI: 10.1016/j.fct.2024.114637] [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: 01/23/2024] [Revised: 03/27/2024] [Accepted: 03/31/2024] [Indexed: 04/08/2024]
Abstract
Diclofenac (DF)-induced acute kidney injury (AKI) is characterized by glomerular dysfunction and acute tubular necrosis. Due to limited treatment approaches, effective and safe drug therapy to protect against such AKI is still needed. Diacetylrhein (DAR), an anthraquinone derivative, has different antioxidant and anti-inflammatory properties. Therefore, the aim of the current study was to investigate the renoprotective effect of DAR on DF-induced AKI while elucidating the potential underlying mechanism. Our results showed that DAR (50 and 100 mg/kg) markedly abrogated DF-induced kidney dysfunction decreasing SCr, BUN, serum NGAL, and serum KIM1 levels. Moreover, DAR treatment remarkably maintained renal redox balance and reduced the levels of pro-inflammatory biomarkers in the kidney. Mechanistically, DAR boosted Nrf2/HO-1 antioxidant and anti-inflammatory response in the kidney while suppressing renal TLR4/NF-κB and NLRP3/caspase-1 inflammatory signaling pathways. In addition, DAR markedly inhibited renal pyroptosis via targeting of GSDMD activation. Collectively, this study confirmed that the interplay between Nrf2/HO-1 and TLR4/NF-κB/NLRP3/Caspase-1 signaling pathways and pyroptotic cell death mediates DF-induced AKI and reported that DAR has a dose-dependent renoprotective effect on DF-induced AKI in rats. This effect is due to powerful antioxidant, anti-inflammatory, and anti-pyroptotic activities that could provide a promising treatment approach to protect against DF-induced AKI.

Behav Brain Res 2023; 438:114143. [PMID: 36206821 DOI: 10.1016/j.bbr.2022.114143] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 09/26/2022] [Accepted: 09/30/2022] [Indexed: 11/16/2022]
Abstract
The long-term effects of cyclooxygenase 1 and 2 (COX-1/2) inhibitors are usually tested in terms of the periphery of the organism. Therefore, we studied the effects of SC560 (selective COX-1 inhibitor) and celecoxib (selective COX-2 inhibitor) on the activity of brain monoaminergic systems and animal behaviour. Additionally, we tested the effect of these inhibitors during inflammation. We have observed that long-term administration of celecoxib reduces the activity of the noradrenergic system, increases the activity of dopaminergic and serotonergic systems, increases locomotor activity, and enhances the exploratory behaviour of rats. Administration of SC560 also increases the activity of dopaminergic and serotonergic systems but reduces locomotor activity and impairs the exploratory behaviour of rats. The mechanism responsible for decreased activity of the noradrenergic system may be related to the weakening of activity of the positive feedback loop between the paraventricular nucleus and coeruleus locus. We suggest that the effect of used inhibitors on the dopaminergic system is associated with a possible increase in anandamide concentration and its effect on dopamine reuptake in synaptic clefts. It also appears that cyclooxygenase peroxidase activity may play a role in this process. In turn, changes in the activity of the serotonergic system may be related to the activity of indoleamine-2,3-dioxygenase, which decreases because of the decreased concentration of pro-inflammatory compounds. We believe that behavioural changes induced by COX inhibitors are the result of the modified activity of monoaminergic CNS systems in the brainstem, hypothalamus, and medial prefrontal cortex.

Abstract
Diclofenac (DIC)-induced acute kidney injury (AKI) causes high morbidity and mortality. With the absence of satisfactory treatment, we investigated the protective effects of 6-Paradol (PDL) against DIC-induced AKI, with focus on renal autophagy and NLRP3 inflammasome pathways . PDL has anti-inflammatory, antioxidant and AMPK-activation properties. PDL was administered to DIC-challenged rats. Nephrotoxicity, oxidative stress, inflammatory, and autophagy markers and histopathological examinations were evaluated. Compared to DIC, PDL restored serum nephrotoxicity, renal oxidative stress and pro-inflammatory markers. PDL almost restored renal architecture, upregulated renal Nrf2 pathway via enhancing Nrf2 mRNA expression and HO-1 levels. PDL suppressed renal NF-κB mRNA expression, and NLRP3 inflammasome pathway expression. Moreover, PDL enhanced renal autophagy through upregulating LC3B, AMPK and SIRT-1, and suppressed mTOR, p-AKT mRNA expressions and phosphorylated-p62 levels. Our study confirmed that autophagy suppression mediates DIC-induced AKI via AMPK/mTOR/AKT and NLRP3-inflammasome pathways. Also, PDL's nephroprotective effects could provide a promising therapeutic approach against DIC-induced AKI.

CHEMOSPHERE 2021; 280:130688. [PMID: 33962297 DOI: 10.1016/j.chemosphere.2021.130688] [Citation(s) in RCA: 20] [Impact Index Per Article: 6.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/22/2021] [Revised: 04/18/2021] [Accepted: 04/21/2021] [Indexed: 05/14/2023]
Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) are medications used individually or as mixtures with other pharmaceuticals for the treatment of various illnesses. Their easy accessibility and high human consumption have resulted to their detection at high concentrations in South African water resources. In the present work, an extensive review of the occurrence and ecotoxicological risk assessment of NSAIDs in South African aquatic environment is provided. Reviewed literature suggested ibuprofen, naproxen, diclofenac, ketoprofen and fenoprofen as the most prominent NSAIDs in the South African aquatic environment. Among these NSAIDs, higher concentrations of ibuprofen are common in South African waters. As a result, this drug was found to pose high ecotoxicological risks towards the aquatic organisms with the highest risk quotients of 14.9 and 11.9 found for algae in surface water and wastewater, respectively. Like in other parts of the world, NSAIDs are not completely removed in wastewater treatment plants. Removal efficiencies below 0% due to higher concentrations of NSAIDs in wastewater effluents rather than influents were observed in certain instances. The detection of NSAIDs in sediments and aquatic plants could serve as the important starting step to investigate other means of NSAIDs removal from water. In conclusion, recommendations regarding future studies that could paint a clearer picture regarding the occurrence and ecotoxicological risks posed by NSAIDs in South African aquatic environment are provided.

JOURNAL OF ETHNOPHARMACOLOGY 2020; 246:112128. [PMID: 31386888 DOI: 10.1016/j.jep.2019.112128] [Citation(s) in RCA: 53] [Impact Index Per Article: 13.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/25/2018] [Revised: 05/29/2019] [Accepted: 07/30/2019] [Indexed: 06/10/2023]
Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Traditional Chinese medicine provides a unique curative treatment of complex chronic diseases, including chronic kidney disease (CKD), which is not effectively treated with the current therapies. The pharmacological mechanisms of Shenkang (SK), a herbal medicine containing rhubarb (Rheum palmatum L. or R. tanguticum Maxim. ex Balf.), red sage (Salvia miltiorrhiza Bunge), safflower (Carthamus tinctorius L.), and astragalus (Astragalus mongholicus Bunge), widely used to treat CKD in China, are still unclear. AIM OF THE STUDY In this study, the comprehensive approach used for elucidating the pharmacological mechanisms of SK included the identification of the effective constituents, target prediction and network analysis, by investigating the interacting pathways between these molecules in the context of CKD. These results were validated by performing an in vivo study and by comparison with literature reviews. MATERIALS AND METHODS This approach involved the following main steps: first, we constructed a molecular database for SK and screened for active molecules by conducting drug-likeness and drug half-life evaluations; second, we used a weighted ensemble similarity drug-targeting model to accurately identify the direct drug targets of the bioactive constituents; third, we constructed compound-target, target-pathway, and target-disease networks using the Cytoscape 3.2 software and determined the distribution of the targets in tissues and organs according to the BioGPS database. Finally, the resulting drug-target mechanisms were compared with those proposed by previous research on SK and validated in a mouse model of CKD. RESULTS By using Network analysis, 88 potential bioactive compounds in the four component herbs of SK and 85 CKD-related targets were identified, including pathways that involve the nuclear factor-κB, mitogen-activated protein kinase, transient receptor potential, and vascular endothelial growth factor, which were categorized as inflammation, proliferation, migration, and permeability modules. The results also included different tissues (kidneys, liver, lungs, and heart) and different disease types (urogenital, metabolic, endocrine, cardiovascular, and immune diseases as well as pathological processes) closely related to CKD. These findings agreed with those reported in the literature. However, our findings with the network pharmacology prediction did not account for all the effects reported for SK found in the literature, such as regulation of the hemodynamics, inhibition of oxidative stress and apoptosis, and the involvement of the transforming growth factor-β/SMAD3, sirtuin/forkhead box protein O (SIRT/FOXO) and B-cell lymphoma-2-associated X protein pathways. The in vivo validation experiment revealed that SK ameliorated CKD through antifibrosis and anti-inflammatory effects, by downregulating the levels of vascular cell adhesion protein 1, vitamin D receptor, cyclooxygenase-2, and matrix metalloproteinase 9 proteins in the unilateral ureteral obstruction mouse model. This was consistent with the predicted target and pathway networks. CONCLUSIONS SK exerted a curative effect on CKD and CKD-related diseases by targeting different organs, regulating inflammation and proliferation processes, and inhibiting abnormal extracellular matrix accumulation. Thus, pharmacological network analysis with in vivo validation explained the potential effects and mechanisms of SK in the treatment of CKD. However, these findings need to be further confirmed with clinical studies.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) should be avoided among chronic kidney disease (CKD) patients. Till now, limited data are available on NSAID use in Egypt, and we aimed to study the prevalence and pattern of NSAID use among CKD patients. METHODS A cross-sectional study was done among 350 CKD adult patients presented to the Main Alexandria University Hospital. Those with end-stage renal disease and diagnosed with acute renal injury and pregnant women were excluded. Demographic and clinical data were collected by interviewing eligible patients. Data about the pattern, history of drug-drug interactions, and knowledge about the NSAID side effects were also gathered. RESULTS Of the enrolled patients, 57.1% were hypertensive, 46% were diabetics, 28% had osteoarthritis, and 18.3% had cardiovascular disease. CKD stages were 3.7%, 40.3%, and 56% in stages 2, 3, and 4, respectively. Almost two thirds (65.7%) were NSAID users. Among them, 82.6% were regular users. Headache was the most reported (68.7%) reason of use. The use of drugs which may have drug-drug interaction with the NSAIDs (as diuretics or renin-angiotensin-aldosterone system inhibitors) was reported in 36%. In multiple logistic regression, the odds of NSAID use decreased by 4% (odds ratio (OR) = 0.96, 95% confidence interval (CI) 0.93-0.99, p = 0.01) for every year increase in the patient's age and decreased by 3% (OR = 0.97, 95% CI 0.95-0.99, p = 0.01) for every 1 ml/min/1.73 m2 increase in glomerular filtration rate. CONCLUSION Despite the hazards of NSAID use on the kidney, still high proportion of CKD patients are using them for a long period and they are simultaneously using other drugs with possible drug-drug interactions. This study provided important information that would decrease the gap in knowledge about the use of NSAID in Egypt. It is recommended that NSAIDs should be used with caution among CKD patients and patients should be advised about its adverse health consequences.

Abstract
AimThis study aimed to explore community pharmacists' roles on screening for risk factors, providing safety information-related non-steroidal anti-inflammatory drugs (NSAIDs) to patients. BACKGROUND: NSAIDs are widely dispensed without a prescription from pharmacies in Thailand, while they are frequently reported as causing adverse events. METHODS: Self-administered questionnaires were distributed to all accredited pharmacies in Thailand, inviting the main pharmacist in each pharmacy to participate in this study.FindingsOut of 406 questionnaires distributed, 159 were returned (39.2%). Almost all pharmacists claimed to engage in NSAID dispensing practice, but not all of them provided relevant good practice, such as, screening for risk factors (56.3-95.5%), communication on adverse drug reactions (ADRs) (36.9-63.2%) and ADR management (58.9-79.7%), history of gastrointestinal (GI) problems was frequently mentioned for screening, but many pharmacists did not screen for history of NSAID use (24.7-35.5%), older age (45.2-48.9%), concomitant drug (63.7%), and problems of cardiovascular (24.1%), renal (34.9-43.3%), and liver systems (60.3-61.0%). Male pharmacists were significantly less likely to inform users of non-selective NSAIDs about ADRs [odds ratio (OR) 0.44], while provision of information about selective NSAID ADRs was higher among pharmacy owners (OR 2.28), pharmacies with more pharmacists (OR 3.18), and lower in pharmacies with assistants (OR 0.41). Screening for risk factors, and risk communication about NSAIDs were not generally conducted in Thai accredited community pharmacists, nor were NSAID complications fully communicated. Promoting of community pharmacists' roles in NSAID dispensing should give priority to improving, especially in high-risk patients for taking NSAIDs.
