In-hospital adverse events and recurrence in hospitalized patients with acute pericarditis. J Cardiol 2023; 82:268-273. [PMID: 36906259 DOI: 10.1016/j.jjcc.2023.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/23/2022] [Revised: 02/04/2023] [Accepted: 02/16/2023] [Indexed: 03/11/2023]
Abstract
BACKGROUND Acute pericarditis occasionally requires invasive treatment, and may recur after discharge. However, there are no studies on acute pericarditis in Japan, and its clinical characteristics and prognosis are unknown. METHODS This was a single-center, retrospective cohort study of clinical characteristics, invasive procedures, mortality, and recurrence in patients with acute pericarditis hospitalized from 2010 to 2022. The primary in-hospital outcome was adverse events (AEs), a composite of all-cause mortality and cardiac tamponade. The primary outcome in the long-term analysis was hospitalization for recurrent pericarditis. RESULTS The median age of all 65 patients was 65.0 years [interquartile range (IQR), 48.0-76.0 years], and 49 (75.3 %) were male. The etiology of acute pericarditis was idiopathic in 55 patients (84.6 %), collagenous in 5 (7.6 %), bacterial in 1 (1.5 %), malignant in 3 (4.6 %), and related to previous open-heart surgery in 1 (1.5 %). Of the 8 patients (12.3 %) with in-hospital AE, 1 (1.5 %) died during hospitalization and 7 (10.8 %) developed cardiac tamponade. Patients with AE were less likely to have chest pain (p = 0.011) but were more likely to have symptoms lasting 72 h after treatment (p = 0.006), heart failure (p < 0.001), and higher levels of C-reactive protein (p = 0.040) and B-type natriuretic peptide (p = 0.032). All patients complicated with cardiac tamponade were treated with pericardial drainage or pericardiotomy. We analyzed 57 patients for recurrent pericarditis after excluding 8 patients: 1 with in-hospital death, 3 with malignant pericarditis, 1 with bacterial pericarditis, and 3 lost to follow-up. During a median follow-up of 2.5 years (IQR 1.3-3.0 years), 6 patients (10.5 %) had recurrences requiring hospitalization. The recurrence rate of pericarditis was not associated with colchicine treatment or aspirin dose or titration. CONCLUSIONS In acute pericarditis requiring hospitalization, in-hospital AE and recurrence were each observed in >10 % of patients. Further large studies on treatment are warranted.

Obstructive uropathy – acute and chronic medical management. World J Nephrol 2023; 12:1-9. [PMID: 36704657 PMCID: PMC9846865 DOI: 10.5527/wjn.v12.i1.1] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 10/27/2022] [Accepted: 12/21/2022] [Indexed: 01/10/2023] Open
Abstract
Obstructive uropathy is an important cause of acute and chronic kidney disease. Decompression of the urinary tract is an essential aspect of treatment. The cause and aetiology of obstruction typically determine the surgical approach. Acute relief of obstruction is frequently complicated by fluid and electrolyte imbalance. Standard therapeutic interventions for acute or chronic renal failure also apply for cases of obstructive uropathy. This narrative review summarises the early and long-term medical management of obstructive uropathy.

Abstract
Various side effects associated with the use of nonsteroidal anti-inflammatory drugs (NSAIDs) in analgesia have been reported. Among the NSAIDs, celecoxib has fewer side effects and is often used in therapeutic applications. However, the effect of celecoxib on aged skin is unknown. In this study, we investigated the effects of celecoxib administration on the skin of aged mice. We analyzed a 40-week-old mouse model and a 10-week-old mice as the control group. The animals were orally administered celecoxib for four consecutive days and then killed and dissected the day after the last dose. In aged mice treated with celecoxib, the water content of the stratum corneum, which is one of the markers of dry skin, was lower than that in the control and young mice groups. In addition, serum hyaluronic acid, creatinine, and inflammatory cytokines in the collected blood samples of aged mice were elevated compared to those in other mice groups, suggesting the onset of acute renal injury. Therefore, it was considered that acute renal injury occurred from the administration of celecoxib to aged mice, whereas dry skin developed by the promotion of inflammatory cytokine secretion and release into the bloodstream in this group.

Time until onset of acute kidney injury by combination therapy with “Triple Whammy” drugs obtained from Japanese Adverse Drug Event Report database. PLoS One 2022; 17:e0263682. [PMID: 35139129 PMCID: PMC8827454 DOI: 10.1371/journal.pone.0263682] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/02/2021] [Accepted: 01/24/2022] [Indexed: 11/25/2022] Open
Abstract
Acute kidney injury (AKI) associated with “Triple Whammy” drug therapy consisting of renin-angiotensin system inhibitors, diuretics, and nonsteroidal anti-inflammatory drugs (NSAIDs) has been reported. There have been no reports investigating “Triple Whammy” drug therapy and the time to AKI onset using adverse drug events report databases. The aim of this study was to determine the relationship between the time to AKI onset and treatment with “Triple Whammy” drug therapy. We analyzed AKI cases registered in the Japanese Adverse Drug Event Report database. The data were analyzed using the Kaplan–Meier approach, generalized Wilcoxon tests, and Weibull distribution. AKI was reported in 18,415 cases, of which 7,466 cases used Triple Whammy drugs. All combinations of Triple Whammy drugs were associated with significantly higher odds ratios for reporting AKI. In Weibull analysis, AKI onset was early for most combination patterns of Triple Whammy drugs. The Kaplan–Meier approach showed that the treatment duration to AKI onset was much shorter in cases using NSAIDs; median onsets, 8 days for triple combination, 7 days for NSAIDs added to renin-angiotensin system inhibitors, 9 days for NSAIDs added to diuretics, 6 days for diuretics added to NSAIDs, and 9 days for NSAIDs alone. AKI associated with Triple Whammy drugs is likely to occur in the early stages of treatment, especially with concomitant NSAIDs. Patients should be monitored for the occurrence of AKI within the first 2 weeks.

Abstract
Acute kidney injury (AKI) is a serious clinical syndrome, and one of the common comorbidities in the perioperative period. AKI can lead to complications in surgical patients and is receiving increasing attention in clinical workup. In recent years, the analysis of perioperative risk factors has become more in-depth and detailed. In this review, the definition, diagnosis, and pathophysiological characteristics of perioperative AKI are reviewed, and the main risk factors for perioperative AKI are analyzed, including advanced age, gender, certain underlying diseases, impaired clinical status such as preoperative creatinine levels, and drugs that may impair renal function such as non-steroidal anti-inflammatory drugs (NASIDs), ACEI/ARB, and some antibiotics. Injectable contrast agents, some anesthetic drugs, specific surgical interventions, anemia, blood transfusions, hyperglycemia, and malnutrition are also highlighted. We also propose potential preventive and curative measures, including the inclusion of renal risk confirmation in the preoperative assessment, minimization of intraoperative renal toxin exposure, intraoperative management and hemodynamic optimization, remote ischemic preadaptation, glycemic control, and nutritional support. Among the management measures, we emphasize the need for careful perioperative clinical examination, timely detection and management of AKI complications, administration of dexmedetomidine for renal protection, and renal replacement therapy. We aim that this review can further increase clinicians' attention to perioperative AKI, early assessment and intervention to try to reduce the risk of AKI.

Abstract
Undesirable side effects of medication are inevitable. Due to the role of the kidneys in clearance and filtration, the renal system faces a unique situation when it comes to the side effects of drugs. It has an important role for different classes of drugs to be excreted, and drugs are a key factor for this system to be at risk. Medications in articles were divided into classes using the standard set by the Saudi Pharmaceutical Journal. Many drug classes cause renal insults. The top six classes were pain killers, antibiotics, proton pump inhibitors, antidiabetics, antihyperlipidemics, and agents for erectile dysfunction. Renal insults caused by these agents could vary in severity. Some drugs could cause nephrotoxicity from one dose, while others may only need continuous monitoring. Different populations also operate under different rules, as some people need dose adjustments while others who are medically free of major illnesses do not. A variety of unfavorable outcomes for the kidney could take place, such as acute kidney injury, chronic kidney disease, and end-stage renal disease, and unfortunately, some of these issues could lead to the need for renal replacement therapies. The outcome of this review paper will help multidisciplinary physicians to understand the renal side effects of the most used drug classes in the Kingdom of Saudi Arabia, their destructive mechanisms, and most importantly, the clinical presentations of renal dysfunction in relation to each class. Emphasizing these adverse effects will prevent future unfavorable outcomes, especially in commonly used drugs that are frequently prescribed for different age groups. Moreover, some of these drugs are considered to be over-the-counter medications, which makes them a serious problem that needs to be handled cautiously.

Comparative Risks of Nonsteroidal Anti-Inflammatory Drugs on CKD. Clin J Am Soc Nephrol 2021; 16:898-907. [PMID: 33910887 PMCID: PMC8216605 DOI: 10.2215/cjn.18501120] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2020] [Accepted: 03/04/2021] [Indexed: 02/04/2023]
Abstract
BACKGROUND AND OBJECTIVES There have been doubts about the association between nonsteroidal anti-inflammatory drug use and worsening kidney function, and whether there is a difference between risks of individual nonsteroidal anti-inflammatory drugs is presently unclear. Therefore, this study aimed to evaluate the association between nonsteroidal anti-inflammatory drug exposure and the risk of incident eGFR <60 ml/min per 1.73 m2 and compare the risks between nonsteroidal anti-inflammatory drug subtypes in the Chinese population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS From 2008 to 2017, a total of 1,982,488 subjects aged 18 years or older with baseline eGFR ≥60 ml/min per 1.73 m2 were enrolled in this retrospective cohort study. Multivariable Cox proportional hazards regression adjusted for each patient's baseline characteristics was adopted to examine the association between nonsteroidal anti-inflammatory drug and incident eGFR <60 ml/min per 1.73 m2 or eGFR decline ≥30% with reference to baseline. RESULTS After a median follow-up duration of 6.3 (interquartile range, 3.3-9.4) years, 271,848 cases (14%) of incident eGFR <60 ml/min per 1.73 m2 and 388,386 (21%) events of eGFR decline ≥30% were recorded. After adjusting for each patient's baseline characteristics, nonsteroidal anti-inflammatory drug treatment was shown to be associated with a significantly higher risk of incident eGFR <60 ml/min per 1.73 m2 (hazard ratio, 1.71; 95% confidence interval, 1.67 to 1.75) and eGFR decline ≥30% (hazard ratio, 1.93; 95% confidence interval, 1.89 to 1.96) when compared with no nonsteroidal anti-inflammatory drug, with etoricoxib exhibiting the highest risk of eGFR<60 ml/min per 1.73 m2 (hazard ratio, 3.12; 95% confidence interval, 2.69 to 3.62) and eGFR decline ≥30% (hazard ratio, 3.11; 95% confidence interval, 2.78 to 3.48) and ibuprofen displaying the lowest risk of eGFR<60 ml/min per 1.73 m2 (hazard ratio, 1.12; 95% confidence interval, 1.02 to 1.23) and eGFR decline ≥30% (hazard ratio, 1.32; 95% confidence interval, 1.23 to 1.41). CONCLUSIONS Nonsteroidal anti-inflammatory drug exposure was associated with higher risks of incident eGFR <60 ml/min per 1.73 m2 and eGFR decline ≥30%. Highest risk was observed in etoricoxib users, and lowest risk was with ibuprofen.

Abstract
Migraine is a common headache disorder that causes significant disabilities. Non-selective cyclooxygenase (COX) inhibitors (piroxicam, ketoprofen and ibuprofen) are most widely-prescribed NSAIDs treatment of headaches. Celecoxib is another NSAID therapy that has been approved in the last several years, with different mechanisms of action. The purpose of the study is to follow the renal function and comparisons of nephrotoxicity of different types of NSAID based on COX inhibition, in patients with cefalea-migraine that has been treated for a long period.
Besides conventional markers of renal function (serum/urine creatinine determined by Jaffe's methods of enzymatic assay for urea in serum), we used nephelometry by β2 microglobulin (β2M) and photoelectric colorimetry for microalbuminuria in urine, to monitor glomerular and tubular functioning. Any history of kidney diseases was exclusion criteria to enter the study.
The results show that the greatest deviations are observed in β2M in terms of its increase in all patients treated with piroxicam and ketoprofen, in 91.7% of the patients treated with ibuprofen, and in 50% of patients treated with celecoxib. The most frequent decrease was shown in creatinine values in urine, in 50% of the patients of piroxicam-treated group, 66.7% of the group treated with ketoprofen and ibuprofen, and 75% of the patients treated with celecoxib.
Following the levels of specific biomarkers in urine we can recommend constant monitoring of renal functions during usage of different groups of NSAIDs and be careful while using analgesic-anti-inflammatory drugs.

Abstract
Pain control during and after any surgical procedure, is extremely essential for the comfort of patients. Pain killers used routinely act by inhibiting cyclooxygenase to control pain and inflammation. Cox-1 is constitutively expressed in most cell types, including platelets, whereas Cox-2 is absent from most healthy tissues but is induced by pro-inflammatory or proliferative stimuli. Cox-1 plays a role in the production of prostaglandins involved in protection of the gastric mucosal layer and thromboxanes (TX) in platelets. Cox-2 generally mediates elevations of prostaglandins associated with inflammation, pain, and pyresis. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen are generally nonselective inhibitors of Coxs. This lack of selectivity has been linked to their propensity to cause gastrointestinal side effects. The new Cox-2 selective inhibitors, or coxibs, show the same anti-inflammatory, analgesic, and antipyretic effects as nonselective NSAIDs but are supposed to have reduced side-effect profiles. This study evaluates whether rofecoxib (50 mg) given one hour pre-operatively or the same drug given one hour post-operatively is more effective in controlling the pain and swelling in mandibular third molar surgery.

Abstract
Spondyloarthritis or spondyloarthropathy (SpA) is a group of related rheumatic disorders, which presents with axial and nonaxial features, affecting structures within the musculoskeletal system, as well as other bodily systems. Both pharmacological and nonpharmacological therapeutic options are available for SpA. For decades, nonsteroidal anti-inflammatory drugs (NSAIDs) have been used as the first-line drugs to treat the disease. Research has shown that other than pain relief, NSAIDs have disease-modifying effects in SpA. However, to achieve these effects, continuous and/or long-term NSAID use is usually required. This review will give an overview of SpA, discuss NSAIDs and their disease-modifying effects in SpA, and highlight some of the important adverse effects of long-term and continuous NSAID use, particularly those related to the gastrointestinal, renal, and cardiovascular systems.

Abstract
Fever depends on a complex physiologic response to infectious agents and other conditions. To alleviate fever, many medicinal agents have been developed over a century of trying to improve upon aspirin, which was determined to work by inhibiting prostaglandin synthesis. We present the process of fever induction through prostaglandin synthesis and discuss the development of pharmaceuticals that target enzymes and receptors involved in prostaglandin-mediated signal transduction, including prostaglandin H2 synthase (also known as cyclooxygenase), phospholipase A2, microsomal prostaglandin E2 synthase-1, EP receptors, and transient potential cation channel subfamily V member 1. Clinical use of established antipyretics will be discussed as well as medicinal agents under clinical trials and future research.

Non-steroidal anti-inflammatory drug induced acute kidney injury in the community dwelling general population and people with chronic kidney disease: systematic review and meta-analysis. BMC Nephrol 2017; 18:256. [PMID: 28764659 PMCID: PMC5540416 DOI: 10.1186/s12882-017-0673-8] [Citation(s) in RCA: 123] [Impact Index Per Article: 17.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/17/2017] [Accepted: 07/19/2017] [Indexed: 12/11/2022] Open
Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs) are a common cause of adverse drug events (ADEs), but renal risks of NSAIDs are less well quantified than gastrointestinal and cardiac risks. This paper reports a systematic review of published population-based observational studies examining the risk of acute kidney injury (AKI) associated with NSAIDs in community-dwelling adults and those with pre-existing chronic kidney disease (CKD). METHODS MEDLINE and EMBASE databases were searched until June 2016, and 3789 papers screened. Ten studies reporting NSAID risk of AKI in the general population were included in random effects meta-analysis, of which five additionally reported NSAID risk in people with CKD. RESULTS In the general population, the pooled odds ratio (OR) of AKI for current NSAID exposure was 1.73 (95%CI 1.44 to 2.07), with somewhat higher risk observed in older people (OR 2.51, 95%CI 1.52 to 2.68). In people with CKD, individual study OR of AKI due to current NSAID exposure ranged from 1.12 to 5.25, with pooled estimate OR 1.63 (95% CI 1.22 to 2.19). CONCLUSIONS No study reported baseline risk of AKI in different populations meaning absolute risks could not be estimated, but baseline risk and therefore the absolute risk of NSAID exposure is likely to be higher in people with CKD and older people. Large population based studies measuring AKI using current definitions and estimating the absolute risk of harm are needed in order to better inform clinical decision making.

Adverse Effects of Oral Nonselective and cyclooxygenase-2-Selective NSAIDs on Hospitalization for Acute Kidney Injury: A Nested Case-Control Cohort Study. Medicine (Baltimore) 2016; 95:e2645.

Abstract
To investigate the association between the use of nonselective or cyclooxygenase (COX)-2-selective nonsteroidal antiinflammatory drugs (NSAIDs) and risk of acute kidney injury (AKI) in a general Asian population. We conducted an observational, nationwide, nested case-control cohort study using Taiwan's National Health Insurance Research Database between 2010 and 2012. AKI cases were defined as hospitalization with a principle diagnosis of AKI. Each case was matched to 4 randomly selected controls based on age, sex, and the month and year of cohort entry. Odds ratios (ORs) were used to demonstrate the association between hospitalization for AKI and current, recent, or past use of an oral NSAID. During the study period, we identified 6199 patients with AKI and 24,796 matched controls. Overall, current users (adjusted OR 2.73, 95% confidence interval [CI] 2.28-3.28) and recent users (adjusted OR 1.17, 95% CI 1.01-1.35) were associated with increased risk of hospitalization for AKI. The risk was also similar for nonselective NSAIDs. However, neither current nor recent use of COX-2 inhibitors was significantly associated with AKI events. Our study supported that the initiation of nonselective NSAIDs rather than COX-2 inhibitors is associated with an increased risk of AKI requiring hospitalization. Future randomized trials are needed to elucidate these findings.

Abstract
Focal Segmental Glomerulosclerosis (FSGS) is a type of nephrotic syndrome which accounts for 20 and 40 % of such cases in children and adults, respectively. The high prevalence of FSGS makes it the most common primary glomerular disorder causing end-stage renal disease. Although the pathogenesis of this disorder has been widely investigated, the exact mechanism underlying this disease is still to be discovered. Current therapies seek to stop the progression of FSGS and often fail to cure the patients since progression to end-stage renal failure is usually inevitable. In the present work, we use a kidney-specific metabolic network model to study FSGS. The model was obtained by merging two previously published kidney-specific metabolic network models. The validity of the new model was checked by comparing the inactivating reaction genes identified in silico to the list of kidney disease implicated genes. To model the disease state, we used a complete list of FSGS metabolic biomarkers extracted from transcriptome and proteome profiling of patients as well as genetic deficiencies known to cause FSGS. We observed that some specific pathways including chondroitin sulfate degradation, eicosanoid metabolism, keratan sulfate biosynthesis, vitamin B6 metabolism, and amino acid metabolism tend to show variations in FSGS model compared to healthy kidney. Furthermore, we computationally searched for the potential drug targets that can revert the diseased metabolic state to the healthy state. Interestingly, only one drug target, N-acetylgalactosaminidase, was found whose inhibition could alter cellular metabolism towards healthy state.

Abstract
PURPOSE Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most frequently used drugs, and this widespread use is complicated by safety issues. METHOD A Literature review was conducted. RESULTS NSAIDs are a leading cause of drug-related morbidity, especially in the elderly and patients with comorbidities. Most adverse effects are related to generalized inhibition of the major targets of NSAIDs: cyclooxygenases I and II. These enzymes are not only involved in pain and inflammation pathogenesis but are also required in the gastrointestinal (GI) tract for mucosal protection and gut motility, and in the kidneys for functional integrity. Thus, the mechanisms of NSAID toxicity are well understood, but the consequences are largely uncontrolled in clinical practice. GI ulcers, including bleeding ulcers, may occur in several percent of all chronic unprotected, high-dose NSAID users. Renal side effects may precipitate renal failure, resulting in acute dialysis and chronic retention. This includes sodium retention, resulting in arterial hypertension, heart failure, and atherosclerotic events. Cardiovascular risk may be tripled by chronic high-dose NSAID use in long-term clinical trials though "real-life studies" indicate lower risk ratios. Off-target side effects include allergic reactions, drug-induced liver injury, and central nervous system effects. CONCLUSIONS Management of pain and inflammation must consider those risks and find alternative drugs or approaches to limit the negative impact of NSAIDs on mortality and morbidity. Alternative drugs, low-dose/short-term use, but especially non-pharmacologic approaches, such as physiotherapy, exercise, neurophysiologic measures, and local therapies, need to be further utilized. The appalling equation "less pain-more deaths/morbidity" ultimately necessitates treatment optimization in the individual patient.

Tetramethylpyrazine (TMP) protects against sodium arsenite-induced nephrotoxicity by suppressing ROS production, mitochondrial dysfunction, pro-inflammatory signaling pathways and programed cell death.

Abstract
Although kidney is a target organ of arsenic cytotoxicity, the underlying mechanisms of arsenic-induced nephrotoxicity remain poorly understood. As tetramethylpyrazine (TMP) has recently been found to be a renal protectant in multiple kidney injuries, we hypothesize that TMP could suppress arsenic nephrotoxicity. In this study, human renal proximal tubular epithelial cell line HK-2 was used to elucidate the precise mechanisms of arsenic nephrotoxicity as well as the protective mechanism of TMP in these cells. Sodium arsenite exposure dramatically increased cellular reactive oxygen species (ROS) production, decreased levels of cellular glutathione (GSH), decreased cytochrome c oxidase activity and mitochondrial membrane potential, which indicated mitochondrial dysfunction. On the other hand, sodium arsenite activated pro-inflammatory signals, including β-catenin, nuclear factor-κB (NF-κB), p38 mitogen-activated protein kinase (MAPK), tumor necrosis factor alpha and cyclooxygenase-2 (COX-2). Small molecule inhibitors of NF-κB and p38 MAPK blocked arsenic-induced COX-2 expression, suggesting arsenic-induced COX-2 up-regulation was NF-κB- and p38 MAPK-dependent. Finally, sodium arsenite induced autophagy in HK-2 cells at early phase (6 h) and the subsequent apoptosis at 24 h. Treatment by TMP or by the antioxidant N-acetylcysteine decreased arsenic-induced ROS production, enhanced GSH levels, prevented mitochondria dysfunction and suppressed the activation of pro-inflammatory signals and the development of autophagy and apoptosis. Our results suggested that TMP may be used as a new potential therapeutic agent to prevent arsenic-induced nephrotoxicity by suppressing these pathological processes.

Abstract
INTRODUCTION In the past, clinical studies had demonstrated that aspirin and NSAIDs reduce the risk of colorectal cancer. After the discovery of selective prostaglandin-endoperoxide synthase 2 (PTGS2) inhibitors, the further beneficial effects of celecoxib and some other related structures (coxibs) have been demonstrated in both in vivo and in vitro studies. AREAS COVERED The authors illustrate the role of prostaglandins following the overexpression of PTGS2 (COX-2) in signaling pathways. The authors elucidate the role of coxibs in cell proliferation, apoptosis, angiogenesis and multi-drug resistance and discuss the molecular mechanisms involved. The authors also present the strong evidence related to the usefulness of coxibs in several cancer cell lines. EXPERT OPINION There have been a number of PTGS2 (COX-2) selective inhibitors suggested as potential anticancer therapies. In recent years, the development of nanotechnology has also had an impact on chemotherapy. Indeed, nanoparticles of cytotoxic drug carriers have demonstrated potential through their accumulation in cancer cells, and targeting these nanoparticles has been under evaluation. This area could be opened up for coxib development as they are potentially important targets in cancer cells. Further research using celecoxib as a co-drug with PTGS2-overexpressed and PTGS2-independent cancer is still needed.

A systematic review of the effect of paracetamol on blood pressure in hypertensive and non-hypertensive subjects. Br J Clin Pharmacol 2014; 75:1396-405. [PMID: 23145789 DOI: 10.1111/bcp.12032] [Citation(s) in RCA: 27] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2012] [Accepted: 11/06/2012] [Indexed: 01/03/2023] Open
Abstract
AIM To review current evidence on the effect of paracetamol on blood pressure (BP), the quality of the previous studies and the validity of the results, and to summarize these findings. METHODS A systematic literature review was performed by searching PubMed, the Cochrane library and EMBASE for publications between the years 1963 and 2012. RESULTS We identified three case reports, seven prospective observational trials, six randomized controlled trials, one commentary and two reviews. Some, but not all, of the observational studies, which included over 147 000 patients, showed an increased risk of hypertension with paracetamol use. The randomized studies were generally small and the results were inconsistent. Three studies, which included 104 patients, showed an increase of systolic BP by ~4 mmHg, two studies, which included 27 patients, reported no change in BP and one study, which included 21 patients, reported a fall in BP although no placebo arm was included for comparison. CONCLUSIONS The overall effect of paracetamol on BP is unclear. Given that paracetamol is often suggested as a safer alternative to non-steroidal anti-inflammatory drugs (NSAIDs), it would seem that further prospective evidence is now needed to address the effect of paracetamol on BP. This would be best done with larger studies in relevant cohorts using BP measured by ambulatory BP monitoring as the primary endpoint.

Abstract
It is known that cyclooxygenase-2 (COX-2) inhibition elicits significant renal hemodynamics alterations when sodium intake is low. However, the mechanisms involved in these renal changes are not well known. Our objective was to evaluate the role of angiotensin II and 5-lipooxygenase-derived metabolites in the renal effects induced by prolonged COX-2 inhibition when sodium intake is low. Conscious dogs were treated during 7 days with a COX-2 inhibitor (1 mg·kg·d, SC75416), and either a vehicle, an AT1 receptor antagonist (0.4 mg · kg · d, candesartan) or a selective 5-lipooxygenase inhibitor (PF-150, 20 and 60 mg · kg · d). The administration of SC75416 alone induced significant changes in renal blood flow (219 ± 14 to 160 ± 10 mL/min), glomerular filtration rate (51 ± 2 to 42 ± 3 mL/min), and plasma potassium (pK) (4.3 ± 0.1 to 4.6 ± 0.1 mEq/L). Similar decrements in renal blood flow (27%) and glomerular filtration rate (20%) and a similar increment in pK (7%) were found when SC75416 was administered in candesartan-pretreated dogs. However, SC75416 administration did not elicit significant changes in renal hemodynamics and pK in dogs pretreated with each dose of PF-150. Our data suggest that leukotrienes but not angiotensin II are involved in the renal effects induced by COX-2 inhibition when sodium intake is low.

Estimated GFR reporting is associated with decreased nonsteroidal anti-inflammatory drug prescribing and increased renal function. Kidney Int 2013; 84:174-8.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used; however, they are also nephrotoxic with both acute and chronic effects on kidney function. Here we determined NSAID prescribing before and after estimated GFR (eGFR) reporting and evaluate renal function in patients who used NSAIDs but stopped these after their first eGFR report. A population-based longitudinal analysis using a record-linkage database was conducted with the GFR estimated using the four-variable equation from the MDRD study and analyzed by trend test, paired t-test, and logistic regression modeling. Prescriptions for NSAIDs significantly decreased from 39,459 to 35,415 after implementation of eGFR reporting from the second quarter of 2005 compared with the first quarter of 2007. Reporting eGFR was associated with reduced NSAID prescriptions (adjusted odds ratio, 0.78). NSAID prescription rates in the 6 months before April 2006 were 18.8, 15.4, and 7.0% in patients with CKD stages 3, 4, and 5 and 15.5, 10.7, and 6.3%, respectively, after eGFR reporting commenced. In patients who stopped NSAID treatment, eGFR significantly increased from 45.9 to 46.9, 23.9 to 27.1, and 12.4 to 26.4 ml/min per 1.73 m2 in 1340 stage 3 patients, 162 stage 4 patients, and 9 stage 5 patients, respectively. Thus, NSAID prescribing decreased after the implementation of eGFR reporting, and there were significant improvements in estimated renal function in patients who stopped taking NSAIDs. Hence, eGFR reporting may result in safer prescribing.

Abstract
Many patients with rheumatic diseases have their management complicated by renal problems. Renal failure modifies the metabolism of many drugs, especially by retention. Questions often arise about the effects of renal failure on the handling of drugs commonly used in rheumatology. For which drugs must we be especially concerned about increased toxicity? Patients on chronic dialysis may also need a variety of drugs for rheumatic disease. How are our drugs dialyzed, and which of these can be safety used and how best to use them?Decisions about dosing of rheumatic drugs are often required for the patients with chronic renal insufficiency or on long-term dialysis, although many drugs have not been formally studied in these settings. Patients with renal insufficiency are excluded from most drug trials. Data for some of these drugs have to be extrapolated based on the information available about the pharmacokinetics of the drug.This review addresses dosing of commonly used drugs in rheumatology in patients with chronic renal insufficiency or failure. It is compiled from a MEDLINE search of papers dealing with renal handling of antirheumatic drugs and suggestions for dose adjustments for these drugs. Drugs reviewed include commonly used disease-modifying antirheumatic drugs (DMARDS), drugs used for treatment of gout, commonly used nonsteroidal antnflammatory drugs (NSAIDS) and the newer COX-2 inhibitors.

Abstract
BACKGROUND Non-steroidal anti-inflammatory drugs (NSAIDs), including cyclooxygenase-2 (COX-2) inhibitors, are generally contraindicated in chronic kidney disease (CKD). This investigation sought to identify the frequency of NSAID/COX-2 prescription and to determine the influence of serum creatinine (Cr) versus estimated glomerular filtration rate (eGFR) on this practice pattern. METHODS An established Veterans Health Administration CKD safety cohort (n = 70,154) was examined to determine the frequency of NSAID/COX-2 in fiscal year 2005 (FY05) for up to 30 days preceding the index hospitalization and as many as 365 days during that year. Binomial regression was used to determine adjusted prevalence ratios for prescription of NSAID/COX-2 with respect to continuous eGFR measurement and serum Cr categories. CKD was defined as eGFR <60 ml/min/1.73 m(2). RESULTS 15.4% of the subjects had an NSAID/COX-2 prescription during the observation period. The proportion of these prescribed agents decreased with declining renal function, but remained significant at any stage of CKD given the renal harm related to these medications. At specific GFR estimates, serum Cr remained a significant predictor of NSAID/COX-2 prescription. At GFR set at 42 ml/min/1.73 m(2), the predicted proportion of prescribed NSAID/COX-2 was 0.29 (95% CI 0.24, 0.36), 0.23 (95% CI 0.22, 0.26), 0.20 (95% CI 0.19, 0.22), and 0.12 (95% CI 0.10, 0.14) for Cr strata of ≤1.3, 1.4-1.6, 1.7-2.1, and ≥2.2 mg/dl, respectively (all p < 0.05). CONCLUSION A significant proportion of individuals with CKD continue to be prescribed NSAID/COX-2 and serum Cr remains an influential guide to NSAID/COX-2 prescription, even in GFR ranges where these agents are ill advised.

Abstract
Management of chronic pain can often be a challenging task, especially in the elderly. Patients over the age of 65 years have altered metabolism and pharmacodynamics that increase their susceptibility to adverse side effects. Nonsteroidal anti-inflammatory drugs (NSAIDs) are a common component of pain management in this population. Nonselective NSAIDs as well as selective Cox-2 inhibitors have been associated with side effects, including renal dysfunction, heart failure, gastrointestinal toxicity and increased risk of cardiovascular side effects. These adverse effects are particularly important in the elderly, and thus use of NSAIDs in this population must be scrutinized carefully. If NSAIDs are utilized, they should be tailored to the individual patient and administered in the lowest dose and for the shortest duration possible. It is hoped that future studies will provide further insight into the safety of these agents in elderly patients.

Abstract
Age-associated endothelium dysfunction is a major risk factor for the development of cardiovascular diseases. Endothelium-synthesized prostaglandins and thromboxane are local hormones, which mediate vasodilation and vasoconstriction and critically maintain vascular homeostasis. Accumulating evidence indicates that the age-related changes in endothelial eicosanoids contribute to decline in endothelium function and are associated with pathological dysfunction. In this review we summarize currently available information on aging-shifted prostaglandin profiles in endothelium and how these shifts are associated with cardiovascular disorders, providing one molecular mechanism of age-associated endothelium dysfunction and cardiovascular diseases.

Abstract
1. Cyclo-oxygenase-2 (COX-2)-derived prostaglandins are important in controlling sodium excretion and renin release. In the present study, we tested the hypothesis that a clinical dose of celecoxib would impair urinary sodium excretion and elevate blood pressure (BP) during dietary salt loading. 2. Twelve normotensive individuals (mean (± SEM) age 35 ± 2 years) completed two separate 17 day dietary perturbations, one taking 200 mg/day celecoxib (CX2) and the other taking placebo (PL), randomized with a 1 month wash out. The controlled 17 day diet consisted of a 3 day run-in diet, 7 days of a low-salt (LS, 20 mmol sodium/day) diet and 7 days of a high-salt diet (HS, 350 mmol sodium/day) diet. The order in which the diets were applied was randomized. Data were collected on the last day of the LS and HS diets. 3. Plasma and urinary prostaglandins were modestly lower during celecoxib (P < 0.05). Urinary sodium excretion was greater (P < 0.01) during the HS diet (253 ± 10 vs 281 ± 27 mmol/24 h for PL vs CX2, respectively) compared with the LS diet (14 ± 3 vs 17 ± 7 mmol/24 h for PL vs CX2, respectively; P(drug) = 0.26). Celecoxib did not alter creatinine clearance (P > 0.50). Twenty-four hour mean arterial BP was similar during PL (87 ± 2 vs 87 ± 2 mmHg for LS and HS, respectively) and CX2 (88 ± 2 vs 87 ± 2 mmHg for LS and HS, respectively; P = 0.85), with no effect of dietary salt (P > 0.80). Plasma renin activity, angiotensin II and aldosterone were all suppressed with dietary salt loading (P < 0.05), with no effect of drug (P > 0.35). 4. In conclusion, blood pressure and renal function were not adversely affected by celecoxib, even during dietary salt loading. These findings support current guidelines suggesting minimal cardiovascular risks associated with short-term, low-dose use of celecoxib in young to middle-aged adults.

Abstract
OBJECTIVE Several nonsteroidal anti-inflammatory drugs (NSAIDs) have been linked to cardiac death. The mechanism that is responsible for this adverse effect appears to be ischemic insult; however, another possible mechanism involves hyperkalemia. The objective of the present study was to determine the feasibility of conducting pharmacoepidemiological studies in Saudi Arabia using refill prescription data to investigate the association between NSAIDs and increased serum potassium concentrations. METHODS This retrospective cohort study included patients from an academic medical center in Riyadh, Saudi Arabia. The patients who were recently prescribed NSAIDs were compared to a control group of paracetamol users, with respect to the drugs' effects on serum potassium concentrations. The covariates that affected the potassium concentration or the use of NSAIDs were controlled for in the analysis. The studied outcome was the first serum potassium concentration of more than 5 mEq/L. RESULTS A total of 184 patients were prescribed NSAIDs (n = 101) or paracetamol (n = 83) and met the inclusion criteria. Compared to the control group, the patients who received NSAIDs were more likely to be women, were less likely to use angiotensin-converting enzyme inhibitors, and were more likely to have lower baseline serum creatinine concentrations. The other baseline characteristics were similar between the patients in the NSAID group and the patients who received paracetamol. Compared to the patients who were prescribed paracetamol, those who were prescribed NSAIDs did not have an increased risk of hyperkalemia (odds ratio, 1.1, 95% confidence interval, 0.17-6.7, P = 0.95). CONCLUSION In the present, small feasibility study, no increase in the risk of hyperkalemia was associated with NSAIDs compared to paracetamol. The present study was exploratory and included only a small number of patients; therefore, this study may not be sufficiently powered to detect small differences between the groups. Future studies with larger sample sizes are needed to investigate the association between NSAIDs and hyperkalemia.

Abstract
Background. Arthritis is a common condition that co-exists in the elderly population. This condition leads to frequent administration of comorbid analgesics especially non steroidal anti-inflammatory drugs (NSAIDs). Aim. To study cardiorenal toxicity of celecoxib versus ibuprofen in arthritic patients. Subjects and Methods. Seven hundred ninety-wo arthritic patients were enrolled in the study for 6 months. Three hundred ninety-six patients administered celecoxib 400 mg twice a day; 396 patients administered ibuprofen 300 mg three times a day. Effects measured included investigator-reported hypertension, edema, or congestive heart failure, increases in serum creatinine or reduction in serum creatinine clearance, and changes in serum electrolytes. Results. Celecoxib was associated with significant (P < .05) lower incidence of hypertension and edema in comparison with ibuprofen. Systolic hypertension occurred significantly less (P < .05) with celecoxib compared with ibuprofen. Serum creatinine was significantly increased (P < .05) in patients treated with ibuprofen in comparison with celecoxib. Creatinine clearance was significantly lower (P < .05) in cases treated with ibuprofen in comparison to celecoxib. Nonsignificant changes in serum body electrolytes occurred. Conclusion. The most important finding of this study was the lowering incidence of cardiorenal toxicity of celecoxib in comparison with ibuprofen.

Abstract
BACKGROUND Selective cyclooxygenase-2 (COX-2) inhibitors have been linked to cardiac death. The mechanism for this adverse effect appears to be by ischemic insult; however another mechanism could involve hyperkalemia. The objective of this study was to determine the effects of selective COX-2 inhibitors and non-selective nonsteroidal anti-inflammatory drugs (NSAIDs) on serum potassium concentration and the electrocardiogram. METHODS A retrospective cohort study was conducted using propensity score matching of patients from an inner-city academic medical center at Indianapolis, Indiana. Two hundred and two patients prescribed selective COX-2 inhibitors were matched to 202 patients prescribed non-selective NSAIDs using propensity scores methods. Outcomes included change in serum potassium concentration from baseline and the risk of an abnormal electrocardiogram. RESULTS Compared to patients prescribed non-selective NSAIDs, those prescribed a selective COX-2 inhibitor had a higher risk of serum potassium increase greater than 5 mEq/L (OR, 2.56; 95%CI, 1.03-6.36). However, patients prescribed selective COX-2 inhibitors had no greater risk of electrocardiogram abnormality (OR, 1.16; 95%CI, 0.74-1.82). CONCLUSIONS Selective COX-2 inhibitors may have a greater risk of hyperkalemia than non-selective NSAIDs. This study was exploratory with small numbers of patients. Further studies are needed to confirm these results and any association with cardiovascular events.

Abstract
The objective of the study was to investigate the effect of diclofenac sodium, when administered similar to its use in clinical practice, 2 weeks following different periods of complete reversible unilateral ureteric obstruction in the rat using accurate indicators of renal function. Male Wistar rats underwent reversible left ureteric obstruction for 2 days [D2-untreated (n = 8) and D2-DS (n = 8) groups] and 5 days [D5-untreated (n = 7) and D5-DS (n = 7) groups]. D2-DS and D5-DS received intramuscular diclofenac sodium (3 mg/kg per day) during the time of obstruction, whereas D2-untreated and D5-untreated groups did not receive any treatment. The renal functions of both kidneys were studied 2 weeks following the reversal. The basal heart rate and mean arterial blood pressure were similar in D2-untreated and D2-DS and in D5-untreated and D5-DS groups. In the D2-untreated group, the GFR and RBF of the left obstructed kidney were 76 and 72% that of the right non-obstructed kidney [0.99 ± 0.06 vs. 1.30 ± 0.08 (P < 0.05) and 4.25 ± 0.33 vs. 5.92 ± 0.61 (P < 0.05), respectively]. The urine volume and urinary and fractional sodium excretion were not significantly different from the right kidney. Similar response was obtained in the D2-DS group. In the D5-untreated group, the GFR and RBF of the left kidney was 66 and 62% that of the right kidney (0.80 ± 0.12 vs. 1.21 ± 0.6, P < 0.05 and 3.79 ± 0.32 vs. 6.16 ± 0.59, P < 0.05; respectively). The tubular functions of both kidneys were similar. In the D5-DS group, there was no difference in GFR or RBF between both kidneys (1.02 ± 0.08 vs. 1.12 ± 0.3, P = 0.24 and 5.10 ± 1.25 vs. 6.46 ± 1.11, P = 0.44, respectively). Similarly, there was no difference in the tubular functions. Treatment with diclofenac sodium during a relatively long period of reversible unilateral ureteric obstruction, similar to its use in the management of ureteric colic, appears to ameliorate the alterations in the hemodynamic glomerular functions at least 2 weeks following the reversal of obstruction.

[PMID: 20732820 DOI: 10.1016/j.cyto.2010.07.004] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2009] [Revised: 06/17/2010] [Accepted: 07/07/2010] [Indexed: 12/18/2022]
Abstract
This study was designed to compare the effect of Aspirin (AS) and Nimesulide (NM) on renal failure and vascular disorder in streptozotocin (STZ)-induced diabetic rats. Rats were divided into four groups; control, diabetic rats, diabetic rats plus AS and diabetic rats plus NM, which are COX inhibitors. The renal and aorta tissues morphology were investigated by light microscopy. Trunk blood was also obtained to determine plasma lipid peroxidation product malondialdehyde (MDA) and plasma activity of antioxidant enzymes. MDA levels were increased in the diabetic rats when compared to the control group. AS and NM administration caused a significant decrease in MDA production. Morphological damage in diabetic rats was severe in the kidney and in the aorta tissue. Treatment of AS reduced these damages, but NM did not exert positive effect on these damages in diabetic rats. As a result, although both AS and NM corrected lipid peroxidation parameters such as MDA via their antioxidant properties, only AS ameliorated pathological alteration in tissues. These findings indicate that there may be another mechanism in beneficial effect of AS in diabetic rats.

Abstract
Non-steroidal anti-inflammatory drugs (NSAIDs) inhibit the isoenzymes COX-1 and COX-2 of cyclooxygenase (COX). Renal side effects (e.g., kidney function, fluid and urinary electrolyte excretion) vary with the extent of COX-2-COX-1 selectivity and the administered dose of these compounds. While young healthy subjects will rarely experience adverse renal effects with the use of NSAIDs, elderly patients and those with co-morbibity (e.g., congestive heart failure, liver cirrhosis or chronic kidney disease) and drug combinations (e.g., renin-angiotensin blockers, diuretics plus NSAIDs) may develop acute renal failure. This review summarizes our present knowledge how traditional NSAIDs and selective COX-2 inhibitors may affect the kidney under various experimental and clinical conditions, and how these drugs may influence renal inflammation, water transport, sodium and potassium balance and how renal dysfunction or hypertension may result.

Abstract
While aspirin may offer protection, other non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) can cause serious cardiovascular side effects and complications. This has led to a general "black box" warning for cardiovascular adverse events for NSAIDs. This review explores the different mechanisms underlying the protective effects of aspirin, the NSAID associated renovascular effects causing hypertension, edema and heart failure, the cardiovascular effects causing myocardial infarction and stroke, and the possible deleterious interaction between NSAIDs and aspirin.

Abstract
BACKGROUND Diclofenac is a proven, commonly prescribed nonsteroidal anti-inflammatory drug (NSAID) that has analgesic, anti-inflammatory, and antipyretic properties, and has been shown to be effective in treating a variety of acute and chronic pain and inflammatory conditions. As with all NSAIDs, diclofenac exerts its action via inhibition of prostaglandin synthesis by inhibiting cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) with relative equipotency. However, extensive research shows the pharmacologic activity of diclofenac goes beyond COX inhibition, and includes multimodal and, in some instances, novel mechanisms of action (MOA). DATA SOURCES Literature retrieval was performed through PubMed/MEDLINE (through May 2009) using combinations of the terms diclofenac, NSAID, mechanism of action, COX-1, COX-2, and pharmacology. Reference citations resulting from publications identified in the literature search were reviewed when appropriate. METHODS This article reviews the established, putative, and emerging MOAs of diclofenac; compares the drug's pharmacologic and pharmacodynamic properties with other NSAIDs to delineate its potentially unique qualities; hypothesizes why it has been chosen for further recent formulation enhancement; and evaluates the potential effect of its MOA characteristics on safety. DISCUSSION Research suggests diclofenac can inhibit the thromboxane-prostanoid receptor, affect arachidonic acid release and uptake, inhibit lipoxygenase enzymes, and activate the nitric oxide-cGMP antinociceptive pathway. Other novel MOAs may include the inhibition of substrate P, inhibition of peroxisome proliferator activated receptor gamma (PPARgamma), blockage of acid-sensing ion channels, alteration of interleukin-6 production, and inhibition of N-methyl-D-aspartate (NMDA) receptor hyperalgesia. The review was not designed to compare MOAs of diclofenac with other NSAIDs. Additionally, as the highlighted putative and emerging MOAs do not have clinical data to demonstrate that these models are correct, further research is necessary to ascertain if the proposed pathways will translate into clinical benefits. The diversity in diclofenac's MOA may suggest the potential for a relatively more favorable profile compared with other NSAIDs.
