Comorbidities, lifestyle, and medications(NSAIDs, low-dose aspirin, antiplatelet agents, anticoagulants, acetaminophen, and corticosteroids) were assessed. After discharge, patients were requested to visit the hospital on scheduled days during the followup period. The Kaplan-Meier method was used to estimate recurrence.RESULTS: Median follow-up was 15 mo. The probability of recurrence at 1, 6, 12, and 24 mo was 3.1%, 19%, 27%, and 38%, respectively. Of the 41 NSAID users on admission, 26(63%) discontinued NSAID use at discharge. Many of the patients who could discontinue NSAIDs were intermittent users, and could be switched to alternative therapies, such as acetaminophen or an antiinflammatory analgesic plaster. The probability of recurrence at 12 mo was 9.4% in discontinuing NSAID users compared with 77% in continuing users(P < 0.01, log-rank test). The hazard ratio for recurrence in the discontinuing NSAIDs users was 0.06 after adjusting for age > 70 years, right-sided diverticula, history of hypertension, and hemodialysis. No patients developed cerebrocardiovascular events during follow-up.CONCLUSION: There is a substantial recurrence rate after discharge among patients hospitalized for diverticular bleeding. Discontinuation of NSAIDs is an effective preventive measure against recurrence. This study provides new information on risk reduction strategies for diverticular bleeding.展开更多

This study assessed the roles of community pharmacists in screening and disseminating information about the risks associated with NSAID use in Zambia. Methodology: This was a national cross-sectional study in which a structured self-administered questionnaire was administered to 245 registered community pharmacists in Zambia. Stata/BE, version 15.1 (Stata Corporation, College Station, Texas, USA) and multivariate logistic regression model was used to determine factors associated with information dissemination about ADRs of NS-NSAIDs. Results: 231 of the 245 distributed questionnaires were returned giving a response rate of 94.3%. All (100%) participating community pharmacists claimed to have practiced dispensing NSAIDs. However, only 26 (11.0%) and 71 (30.8%) regularly screened for risk factor of selective COX-2 NSAIDS (SC2-NSAIDS) and non-selective NSAIDS (NS-NSAIDs) respectively. Information dissemination on adverse drug reactions (ADRs) of SC2-NSAIDS was regularly provided by only 22 (9.5%) of pharmacists while that of NS-NSAIDs was regularly provided by 49 (21.2%). In the multivariate logistic regression model, being the owner of a pharmacy (AOR: 5.4, CI: 1.84 - 16.4) was significantly associated with information dissemination about ADRs of NS-NSAIDs while an hour increase in the working hours per day (AOR: 0.9, CI: 0.64 - 0.95) was associated with less likelihood of information dissemination. Conclusion: Pharmacists working in community pharmacies in Zambia did not regularly screen and disseminate information about the risks associated with NSAID use. Therefore, pharmacists should be able to screen and monitor patients at risk and be aware of the majority of risk factors while dispensing NSAIDs to minimize the associated complications.展开更多

Thus, not surprisingly NSAIDs, along with antiinfectious agents, list on the top for causes of DrugInduced Liver Injury (DILI). The incidence of liver disease induced by NSAIDs reported in clinical studies is fairly uniform ranging from 0.29/100 000 [95% confidence interval (CI): 0.17-051] to 9/100 000 (95% CI: 6-15). However, compared with these results, a higher risk of liver-related hospitalizations was reported (3-23 per 100 000 patients). NSAIDs exhibit a broad spectrum of liver damage ranging from asymptomatic, transient, hyper-transaminasemia to fulminant hepatic failure. However, under-reporting of asymptomatic, mild cases, as well as of those with transient liver-tests alteration, in conjunction with reports non-compliant with pharmacovigilance criteria to ascertain DILI and flawed epidemiological studies, jeopardize the chance to ascertain the actual risk of NSAIDs hepatotoxicity. Several NSAIDs, namely bromfenac, ibufenac and benoxaprofen, have been withdrawn from the market due to hepatotoxicity; others like nimesulide were never marketed in some countries and withdrawn in others. Indeed, the contro-versy concerning the actual risk of severe liver disease persists within NSAIDs research. The present work intends (1) to provide a critical analysis of the dissimilar results currently available in the literature concerning the epidemiology of NSAIDS hepatotoxicity; and (2) to review the risk of hepatotoxicity for each one of the most commonly employed compounds of the NSAIDs family, based on past and recently published data.展开更多

METHODS: A systematic literature search(MEDLINE, Embase and the Cochrane Library, from inception of the databases until May 2015) was conducted to identify randomized, clinical trials investigating the role of NSAIDs in reducing the risk of post-ERCP pancreatitis. Random effects model of the meta-analysis was carried out, and results were presented as odds ratios(OR) with corresponding 95%CI.RESULTS: Thirteen randomized controlled trials on 3378 patients were included in the final meta-analysis. There were 1718 patients in the NSAIDs group and 1660 patients in non-NSAIDs group undergoing ERCP. The use of NSAIDs(through rectal route or intramuscular route) was associated with the reduced risk of post-ERCP pancreatitis [OR, 0.52(0.38-0.72), P = 0.0001]. The use of pre-procedure NSAIDs was effective in reducing approximately 48% incidence of post-ERCP pancreatitis, number needed to treat were 16 with absolute risk reduction of 0.05. But the risk of post-ERCP pancreattis was reduced by 55% if NSAIDs were administered after procedure. Similarly, diclofenac was more effective(55%) prophylactic agent compared to indomethacin(41%).CONCLUSION: NSAIDs seem to have clinically proven advantage of reducing the risk of post-ERCP pancreatitis.展开更多

We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber(physician or selfmedication) were examined. RESULTS: Fifty-one patients, including 34 males, were enrolled(median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients(68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients(56.9%)]. Seven patients had positive family history of Helicobacter pylori(H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four(47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom(33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51(62%) patients, duodenal lesions in 17(33%) and esophageal lesions in 8(15%). In 10/51(19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight(94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51(6%) patients, an endoscopic hemostasis was needed.CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in展开更多

The literature sources, from which the false perspective derives, do not accurately reflect safety and fail to address the value of appropriate drug use monitoring.We, as rheumatologists, must stand up and proactively address engrained misconceptions-if we are to be able to continue to provide safe, effective care for our patients.展开更多

NSAIDs use could be associated with elevated eosinophil count which could be a class effect or patient-related. Inflammation could be the link between NSAIDs use and eosinophilia. <strong>Aims: </strong>To compare the pattern of eosinophil count in the peripheral blood of frequent users of NSAIDs and healthy controls. <strong>Methodology: </strong>Two hundred (one hundred frequent users of NSAIDs and 100 healthy controls) participants who had no known risk factor for kidney disease and had given informed consent were recruited. Blood was taken to determine the white cell count and differentials, serum electrolyte and creatinine, and random blood sugar. <strong>Results:</strong> The mean age of NSAIDs users was not significantly different from controls, P = 0.3. The mean eosinophil count was higher in males than females. The incidence of eosinophilia in NSAIDs users was 4%. The mean Eosinophil count of NSAIDs users was insignificantly higher than controls, 164.3 ± 51 6 vs 135. 6 ± 53.4, P = 0.4. The mean platelet count of NSAIDs users was significantly higher compared to controls, P = 0.04. The mean hematocrit of NSAIDs users was significantly lower than the controls, P = 0.02. Propionic acid derivatives were associated with the highest eosinophil count. Eosinophil count was positively related to age and serum creatinine and inversely related to blood glucose, hematocrit and glomerular filtration rate.<strong> Conclusion: </strong>The incidence of eosinophilia was 4%. The eosinophil count was higher in frequent NSAIDs users than occasional and non-users, in males than females and with use propionic acid derivatives compared to other NSAIDs. The Eosinophil count was positively related to age and platelet count. Being commoner in inflammatory states, the tissue destruction associated with elevated EC can be avoided by the prevention and prompt treatment of inflammatory conditions.展开更多

The mainstay of medical pain therapy remains drugs that have been around for decades, like non-steroidal anti-inflammatory drugs (NSAIDs), or opiates. However, adverse effects of opiates, particularly tolerance, limit their clinical use. Several lines of investigations have shown that systemic (intraperitoneal) administration of NSAIDs induces antinociception with some effects of tolerance. In this review, we report that repeated microinjection of NSAIDs analgin, clodifen, ketorolac and xefocam into the central nucleus of amygdala, the midbrain periaqueductal grey matter and nucleus raphe magnus in the following 4 days result in progressively less antinociception compared to the saline control testing in the tail-flick reflex and hot plate latency tests. Hence, tolerance develops to these drugs and cross-tolerance to morphine in male rats. These findings strongly support the suggestion of endogenous opioid involvement in NSAIDs antinociception and tolerance in the descending pain-control system. Moreover, the periaqueductal grey-rostral ventro-medial part of medulla circuit should be viewed as a pain-modulation system. These data are important for human medicine. In particular, cross-tolerance between non-opioid and opioid analgesics should be important in the clinical setting.展开更多

In fact, survival after stroke diminishes largely with aging. In fact, recovery after brain artery occlusion is dramatically worsened by aging, even normal aging is associated with neuron damage and cognitive decline. Mechanisms involved in aging-related, cognitive decline and susceptibility to neuron damage in stroke and neurode- generation are largely unknown. One of the most important mech- anisms contributing to neural dysfunction and death is excitotox- icity. This process is based on the fact that the excessive glutamate receptor stimulation may lead to neuronal damage. This overstim- ulation may be due to increased concentration of glutamate, or the prolonged activation of receptors.展开更多

A 41-year-old pharmacologist with no family history of intestinal polyps or cancer chronically consumed daily aspirin and other non-steroidal anti-inflammatory drugs for decades despite recurrent and multiple gastric ulcers. A cancerous polyp in the colon was endoscopically resected. Over the next 2 decades, almost 50 adenomatous polyps were removed from the rest of his colon and duodenum, typical of an attenuated form of adenomatous polyposis. Chronic and habitual use of aspirin or NSAIDS may have important significance in delaying the appearance of adenomas. The observations here emphasize the important implications for clinical risk assessment in screening programs designed to detect or prevent colon cancer.展开更多

To control the abuse of these agents in racehorses competing in PA, a forensic method for screening and confirmation of the presence of these agents is needed. Equine plasma (0.5 mL) was acidified with 75 μL 1M H3PO4 to increase recovery of the analytes by liquid-liquid extraction using methyl tert-butyl ether (MTBE). Extracted analytes were separated by reversed-phase liquid chromatography using a C8 column under gradient condition. All 16 analytes were detected, quantified and confirmed using a triple quadrupole tandem mass spectrometry with selected reaction monitoring (SRM) in both negative and positive electrospray ionization modes. The limit of detection, quantification and confirmation of the analytes were 1.0 - 5.0 ng/mL, 1.0 - 5.0 ng/mL and 1.0 - 20 ng/mL, respectively. The linear dynamic range of quantification was 5.0 - 200 ng/mL. The method is routinely used in anti-doping analysis to control the abuse of NSAIDs in racehorses competing in PA.展开更多

They are available as cheap, over-the-counter drugs, and commonly abused. NSAIDs inhibit prostaglandins (PGs) actions on the kidneys and can cause kidney disease and hypertension, especially when used in excess doses, for prolonged period or in stressed states. Methods: The descriptive study was carried at the Orthopaedic and Family Medicine units of the Federal Medical Centre, Abeokuta. Two hundred respondents participated in the study. One hundred frequent users of NSAIDs (with daily use for ≥ 4 weeks) and age and sex-matched controls with no known risk for kidney disease and had consented were consecutively recruited. Data were entered from history, examination and investigations (urinalysis, serum electrolyte, kidney scan and biopsy). Cases with estimated glomerular filtration rate (eGFR) 2) and dip strip proteinuria ≥ 1+ had kidney biopsy. Statistical analysis was with SPSS 21 software. Student t-test and Chi-square tests were used to compare means and proportions respectively. Pearson’s correlation test was used to determine the strength of association between independent risk factors and kidney dysfunction (KD). Results: Two hundred respondents participated in the study. Fifty one (51) females and Forty nine (49) males were recruited as cases and controls respectively. Thirteen (13) females had KD compared to 9 males, (P = 0.02). The mean age of cases with KD (63.04 yrs ± 4.21) was statistically higher than those without KD (P = 0.01). Majority of the cases were in the working population (30 - 59 yrs). Twenty two (22) frequent NSAIDs users had kidney dysfunction (KD) while six (6%) controls had KD. The proportion of subjects that used herbal medicines was higher in cases with KD than in cases without KD as well as in the controls respectively (P = 0.01). The mean kidney length and cortical thickness were significantly lower in cases with KD than in cases without KD, (P = 0.03) and (P = 0.017) respectively. The independent predictors of KD were increasing age, use of herbal remedies and duration of drug use. Conclusion: The prevalence of KD among frequent NSAIDs users was 22%, higher than controls. Risk factors identified include increasing age, use of herbal medicines, increasing body mass index (BMI), systolic blood pressure (SBP), anaemia, reduced cortical thickness and kidney volume. NSAIDs use in excess doses, prolonged period or in stressed state increases the risk for kidney dysfunction, caution is therefore needed to avoid taking these drugs in these conditions.展开更多

文摘AIM: To determine the effect of discontinuing nonsteroidal antiinflammatory drugs(NSAIDs) on recurrence in long-term follow-up patients with colonic diverticular bleeding(CDB).METHODS: A cohort of 132 patients hospitalized for CDB examined by colonoscopy was prospectively enrolled. Comorbidities, lifestyle, and medications(NSAIDs, low-dose aspirin, antiplatelet agents, anticoagulants, acetaminophen, and corticosteroids) were assessed. After discharge, patients were requested to visit the hospital on scheduled days during the followup period. The Kaplan-Meier method was used to estimate recurrence.RESULTS: Median follow-up was 15 mo. The probability of recurrence at 1, 6, 12, and 24 mo was 3.1%, 19%, 27%, and 38%, respectively. Of the 41 NSAID users on admission, 26(63%) discontinued NSAID use at discharge. Many of the patients who could discontinue NSAIDs were intermittent users, and could be switched to alternative therapies, such as acetaminophen or an antiinflammatory analgesic plaster. The probability of recurrence at 12 mo was 9.4% in discontinuing NSAID users compared with 77% in continuing users(P < 0.01, log-rank test). The hazard ratio for recurrence in the discontinuing NSAIDs users was 0.06 after adjusting for age > 70 years, right-sided diverticula, history of hypertension, and hemodialysis. No patients developed cerebrocardiovascular events during follow-up.CONCLUSION: There is a substantial recurrence rate after discharge among patients hospitalized for diverticular bleeding. Discontinuation of NSAIDs is an effective preventive measure against recurrence. This study provides new information on risk reduction strategies for diverticular bleeding.
文摘Background: The increasing use of non-steroidal anti-inflammatory drugs (NSAIDs) both on prescription and over the counter raises a major global health concern because of the risks associated with their use if no proper guidance is given by the health care provider. This study assessed the roles of community pharmacists in screening and disseminating information about the risks associated with NSAID use in Zambia. Methodology: This was a national cross-sectional study in which a structured self-administered questionnaire was administered to 245 registered community pharmacists in Zambia. Stata/BE, version 15.1 (Stata Corporation, College Station, Texas, USA) and multivariate logistic regression model was used to determine factors associated with information dissemination about ADRs of NS-NSAIDs. Results: 231 of the 245 distributed questionnaires were returned giving a response rate of 94.3%. All (100%) participating community pharmacists claimed to have practiced dispensing NSAIDs. However, only 26 (11.0%) and 71 (30.8%) regularly screened for risk factor of selective COX-2 NSAIDS (SC2-NSAIDS) and non-selective NSAIDS (NS-NSAIDs) respectively. Information dissemination on adverse drug reactions (ADRs) of SC2-NSAIDS was regularly provided by only 22 (9.5%) of pharmacists while that of NS-NSAIDs was regularly provided by 49 (21.2%). In the multivariate logistic regression model, being the owner of a pharmacy (AOR: 5.4, CI: 1.84 - 16.4) was significantly associated with information dissemination about ADRs of NS-NSAIDs while an hour increase in the working hours per day (AOR: 0.9, CI: 0.64 - 0.95) was associated with less likelihood of information dissemination. Conclusion: Pharmacists working in community pharmacies in Zambia did not regularly screen and disseminate information about the risks associated with NSAID use. Therefore, pharmacists should be able to screen and monitor patients at risk and be aware of the majority of risk factors while dispensing NSAIDs to minimize the associated complications.
文摘The goals of global vaccination are to control,eliminate,or eradicate infectious diseases in a sustainable way that strengthens public health systems.Although the use of vaccines is essential for the control of epidemics,the vaccines against coronavirus disease 2019(COVID-19)proved to be inadequate to end the pandemic and thus are considered incomplete.These vaccines failed to prevent infection,so their primary purpose has been shifted to prevent severe disease and reduce hospitalizations and deaths.Therefore,we believe that all the strategies available to reduce transmission,hospitalizations and deaths due to COVID-19 will be put in place.It is reported that uncontrolled inflammation and thrombosis are the principal mechanisms for aggravation and death in patients with COVID-19.Unlike corticosteroids that should not be administered at the beginning of the symptoms for their immunosuppressive action,which could worsen the evolution of the disease,the usefulness of non-steroidal anti-inflammatory drugs in the early at-home treatment of the disease is becoming evident.
文摘Endoscopic ultrasound(EUS)with fine needle aspiration or fine needle biopsy is the gold standard for sampling tissue to diagnose pancreatic cancer and auto-immune pancreatitis or to analyze cyst fluid.The most common reported adverse event of fine needle aspiration and/or fine needle biopsy is acute pancreatitis,which is likely induced by the same pathophysiological mechanisms as after en-doscopic retrograde cholangiopancreatography(ERCP).According to the current European Society of Gastrointestinal Endoscopy guideline,nonsteroidal anti-inflammatory drugs are administered prior to ERCP as a scientifically proven treatment to reduce post-ERCP pancreatitis incidence rate.A single suppository of diclofenac or indomethacin prior to EUS guided tissue acquisition(TA)is harm-less in healthy adults.Since it is associated with low costs and,most important,may prevent a dreadsome complication,we strongly recommend the adminis-tration of 100 mg diclofenac rectally prior to EUS-TA.We will explain this recom-mendation in more detail in this review as well as the risk and pathophysiology of post-EUS TA pancreatitis.

文摘BACKGROUND Various non-steroidal anti-inflammatory drugs(NSAIDs)have been used for juvenile idiopathic arthritis(JIA).However,the optimal method for JIA has not yet been developed.AIM To perform a systematic review and network meta-analysis to determine the optimal instructions.METHODS We searched for randomized controlled trials(RCTs)from PubMed,EMBASE,Google Scholar,CNKI,and Wanfang without restriction for publication date or language at August,2023.Any RCTs that comparing the effectiveness of NSAIDs with each other or placebo for JIA were included in this network meta-analysis.The surface under the cumulative ranking curve(SUCRA)analysis was used to rank the treatments.P value less than 0.05 was identified as statistically significant.RESULTS We included 8 RCTs(1127 patients)comparing 8 different instructions including meloxicam(0.125 qd and 0.250 qd),Celecoxib(3 mg/kg bid and 6 mg/kg bid),piroxicam,Naproxen(5.0 mg/kg/d,7.5 mg/kg/d and 12.5 mg/kg/d),inuprofen(30-40 mg/kg/d),Aspirin(60-80 mg/kg/d,75 mg/kg/d,and 55 mg/kg/d),Tolmetin(15 mg/kg/d),Rofecoxib,and placebo.There were no significant differences between any two NSAIDs regarding ACR Pedi 30 response.The SUCRA shows that celecoxib(6 mg/kg bid)ranked first(SUCRA,88.9%),rofecoxib ranked second(SUCRA,68.1%),Celecoxib(3 mg/kg bid)ranked third(SUCRA,51.0%).There were no significant differences between any two NSAIDs regarding adverse events.The SUCRA shows that placebo ranked first(SUCRA,88.2%),piroxicam ranked second(SUCRA,60.5%),rofecoxib(0.6 mg/kg qd)ranked third(SUCRA,56.1%),meloxicam(0.125 mg/kg qd)ranked fourth(SUCRA,56.1%),and rofecoxib(0.3 mg/kg qd)ranked fifth(SUCRA,56.1%).CONCLUSION In summary,celecoxib(6 mg/kg bid)was found to be the most effective NSAID for treating JIA.Rofecoxib,piroxicam,and meloxicam may be safer options,but further research is needed to confirm these findings in larger trials with higher quality studies.
文摘Non-steroidal anti-inflammatory drugs (NSAIDs) constitute a family of drugs, which taken as a group, represents one of the most frequently prescribed around the world. Thus, not surprisingly NSAIDs, along with antiinfectious agents, list on the top for causes of DrugInduced Liver Injury (DILI). The incidence of liver disease induced by NSAIDs reported in clinical studies is fairly uniform ranging from 0.29/100 000 [95% confidence interval (CI): 0.17-051] to 9/100 000 (95% CI: 6-15). However, compared with these results, a higher risk of liver-related hospitalizations was reported (3-23 per 100 000 patients). NSAIDs exhibit a broad spectrum of liver damage ranging from asymptomatic, transient, hyper-transaminasemia to fulminant hepatic failure. However, under-reporting of asymptomatic, mild cases, as well as of those with transient liver-tests alteration, in conjunction with reports non-compliant with pharmacovigilance criteria to ascertain DILI and flawed epidemiological studies, jeopardize the chance to ascertain the actual risk of NSAIDs hepatotoxicity. Several NSAIDs, namely bromfenac, ibufenac and benoxaprofen, have been withdrawn from the market due to hepatotoxicity; others like nimesulide were never marketed in some countries and withdrawn in others. Indeed, the contro-versy concerning the actual risk of severe liver disease persists within NSAIDs research. The present work intends (1) to provide a critical analysis of the dissimilar results currently available in the literature concerning the epidemiology of NSAIDS hepatotoxicity; and (2) to review the risk of hepatotoxicity for each one of the most commonly employed compounds of the NSAIDs family, based on past and recently published data.
文摘AIM: To critically appraise the published randomized, controlled trials on the prophylactic effectiveness of the non-steroidal anti-inflammatory drugs(NSAIDs), in reducing the risk of post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis. METHODS: A systematic literature search(MEDLINE, Embase and the Cochrane Library, from inception of the databases until May 2015) was conducted to identify randomized, clinical trials investigating the role of NSAIDs in reducing the risk of post-ERCP pancreatitis. Random effects model of the meta-analysis was carried out, and results were presented as odds ratios(OR) with corresponding 95%CI.RESULTS: Thirteen randomized controlled trials on 3378 patients were included in the final meta-analysis. There were 1718 patients in the NSAIDs group and 1660 patients in non-NSAIDs group undergoing ERCP. The use of NSAIDs(through rectal route or intramuscular route) was associated with the reduced risk of post-ERCP pancreatitis [OR, 0.52(0.38-0.72), P = 0.0001]. The use of pre-procedure NSAIDs was effective in reducing approximately 48% incidence of post-ERCP pancreatitis, number needed to treat were 16 with absolute risk reduction of 0.05. But the risk of post-ERCP pancreattis was reduced by 55% if NSAIDs were administered after procedure. Similarly, diclofenac was more effective(55%) prophylactic agent compared to indomethacin(41%).CONCLUSION: NSAIDs seem to have clinically proven advantage of reducing the risk of post-ERCP pancreatitis.
文摘AIM: To investigate gastrointestinal complications associated with non-steroidal anti-inflammatory drug(NSAIDs) use in children.METHODS: A retrospective, multicenter study was conducted between January 2005 and January 2013, with the participation of 8 Italian pediatric gastroenterology centers. We collected all the cases of patients who refer to emergency room for suspected gastrointestinal bleeding following NSAIDs consumption, and underwent endoscopic evaluation. Previous medical history, associated risk factors, symptoms and signs at presentation, diagnostic procedures, severity of bleeding and management of gastrointestinal bleeding were collected. In addition, data regarding type of drug used, indication, dose, duration of treatment and prescriber(physician or selfmedication) were examined. RESULTS: Fifty-one patients, including 34 males, were enrolled(median age: 7.8 years). Ibuprofen was the most used NSAID [35/51 patients(68.6%)]. Pain was the most frequent indication for NSAIDs use [29/51 patients(56.9%)]. Seven patients had positive family history of Helicobacter pylori(H. pylori) infection or peptic ulcer, and 12 had associated comorbidities. Twenty-four(47%) out of 51 patients used medication inappropriately. Hematemesis was the most frequent symptom(33.3%). Upper gastrointestinal endoscopy revealed gastric lesions in 32/51(62%) patients, duodenal lesions in 17(33%) and esophageal lesions in 8(15%). In 10/51(19.6%) patients, a diagnosis of H. pylori gastritis was made. Forty-eight(94%) patients underwent medical therapy, with spontaneous bleeding resolution, while in 3/51(6%) patients, an endoscopic hemostasis was needed.CONCLUSION: The data collected in this study confirms that adverse events with the involvement of the gastrointestinal tract secondary to NSAID use are also common in
文摘BACKGROUND Non-steroidal anti-inflammatory drugs(NSAIDs)are among the most commonly prescribed medications in the United States.Although they are safe and effective means of analgesia for children with broken bones,there is considerable variation in their clinical use due to persistent concerns about their potentially adverse effect on fracture healing.AIM To assess whether NSAID exposure is a risk factor for fracture nonunion in children.METHODS We systematically reviewed the literature reporting the effect of NSAIDs on bone healing.We included all clinical studies that reported on adverse bone healing complications in children with respect to NSAID exposure.The outcomes of interest were delayed union or nonunion.Study quality was assessed using the Newcastle-Ottawa scale for non-randomized studies.A final table was constructed summarizing the available evidence.RESULTS A total of 120 articles were identified and screened,of which 6 articles were included for final review.Nonunion in children is extremely rare;among the studies included,there were 2011 nonunions among 238822 fractures(0.84%).None of the included studies documented an increased risk of nonunion or delayed bone healing in those children who are treated with NSAIDs in the immediate post-injury or peri-operative time period.Additionally,children are likely to take these medications for only a few days after injury or surgery,further decreasing their risk of adverse side-effects.CONCLUSION This systematic review suggests that NSAIDS can be safely prescribed to pediatric orthopaedic patients absent other contraindications without concern for increased risk of fracture non-union or delayed bone healing.Additional prospective studies are needed focusing on higher risk fractures and elective orthopaedic procedures such as osteotomies and spinal fusion.
文摘Non-steroidal anti-inflammatory drugs have a fundamental and pivotal position in management of many of the disorders managed by rheumatologists.Promulgation of a false perspective of their toxicity has compromised our ability to advise our patients and participate in the management of their disorders. The literature sources, from which the false perspective derives, do not accurately reflect safety and fail to address the value of appropriate drug use monitoring.We, as rheumatologists, must stand up and proactively address engrained misconceptions-if we are to be able to continue to provide safe, effective care for our patients.
文摘<strong>Introduction: </strong>Non-steroidal anti-inflammatory drugs (NSAIDs) use is very common. NSAIDs use could be associated with elevated eosinophil count which could be a class effect or patient-related. Inflammation could be the link between NSAIDs use and eosinophilia. <strong>Aims: </strong>To compare the pattern of eosinophil count in the peripheral blood of frequent users of NSAIDs and healthy controls. <strong>Methodology: </strong>Two hundred (one hundred frequent users of NSAIDs and 100 healthy controls) participants who had no known risk factor for kidney disease and had given informed consent were recruited. Blood was taken to determine the white cell count and differentials, serum electrolyte and creatinine, and random blood sugar. <strong>Results:</strong> The mean age of NSAIDs users was not significantly different from controls, P = 0.3. The mean eosinophil count was higher in males than females. The incidence of eosinophilia in NSAIDs users was 4%. The mean Eosinophil count of NSAIDs users was insignificantly higher than controls, 164.3 ± 51 6 vs 135. 6 ± 53.4, P = 0.4. The mean platelet count of NSAIDs users was significantly higher compared to controls, P = 0.04. The mean hematocrit of NSAIDs users was significantly lower than the controls, P = 0.02. Propionic acid derivatives were associated with the highest eosinophil count. Eosinophil count was positively related to age and serum creatinine and inversely related to blood glucose, hematocrit and glomerular filtration rate.<strong> Conclusion: </strong>The incidence of eosinophilia was 4%. The eosinophil count was higher in frequent NSAIDs users than occasional and non-users, in males than females and with use propionic acid derivatives compared to other NSAIDs. The Eosinophil count was positively related to age and platelet count. Being commoner in inflammatory states, the tissue destruction associated with elevated EC can be avoided by the prevention and prompt treatment of inflammatory conditions.

文摘Pain is a sensation related to potential or actual damage in some tissue of the body. The mainstay of medical pain therapy remains drugs that have been around for decades, like non-steroidal anti-inflammatory drugs (NSAIDs), or opiates. However, adverse effects of opiates, particularly tolerance, limit their clinical use. Several lines of investigations have shown that systemic (intraperitoneal) administration of NSAIDs induces antinociception with some effects of tolerance. In this review, we report that repeated microinjection of NSAIDs analgin, clodifen, ketorolac and xefocam into the central nucleus of amygdala, the midbrain periaqueductal grey matter and nucleus raphe magnus in the following 4 days result in progressively less antinociception compared to the saline control testing in the tail-flick reflex and hot plate latency tests. Hence, tolerance develops to these drugs and cross-tolerance to morphine in male rats. These findings strongly support the suggestion of endogenous opioid involvement in NSAIDs antinociception and tolerance in the descending pain-control system. Moreover, the periaqueductal grey-rostral ventro-medial part of medulla circuit should be viewed as a pain-modulation system. These data are important for human medicine. In particular, cross-tolerance between non-opioid and opioid analgesics should be important in the clinical setting.

文摘The most important risk factor for stroke and neurodegeneration is aging. In fact, survival after stroke diminishes largely with aging. In fact, recovery after brain artery occlusion is dramatically worsened by aging, even normal aging is associated with neuron damage and cognitive decline. Mechanisms involved in aging-related, cognitive decline and susceptibility to neuron damage in stroke and neurode- generation are largely unknown. One of the most important mech- anisms contributing to neural dysfunction and death is excitotox- icity. This process is based on the fact that the excessive glutamate receptor stimulation may lead to neuronal damage. This overstim- ulation may be due to increased concentration of glutamate, or the prolonged activation of receptors.
文摘Aspirin and non-steroidal anti-inflammatory drugs (NSAIDS) may prevent sporadic colonic neoplasia and reduce the polyp burden in familial adenomatous polyposis. A 41-year-old pharmacologist with no family history of intestinal polyps or cancer chronically consumed daily aspirin and other non-steroidal anti-inflammatory drugs for decades despite recurrent and multiple gastric ulcers. A cancerous polyp in the colon was endoscopically resected. Over the next 2 decades, almost 50 adenomatous polyps were removed from the rest of his colon and duodenum, typical of an attenuated form of adenomatous polyposis. Chronic and habitual use of aspirin or NSAIDS may have important significance in delaying the appearance of adenomas. The observations here emphasize the important implications for clinical risk assessment in screening programs designed to detect or prevent colon cancer.
文摘Non-steroidal anti-inflammatory drugs (NSAIDs) are classified as Class 4 agents by the Association of Racing Commissioners International and are banned in racehorses during competition in Pennsylvania (PA). To control the abuse of these agents in racehorses competing in PA, a forensic method for screening and confirmation of the presence of these agents is needed. Equine plasma (0.5 mL) was acidified with 75 μL 1M H3PO4 to increase recovery of the analytes by liquid-liquid extraction using methyl tert-butyl ether (MTBE). Extracted analytes were separated by reversed-phase liquid chromatography using a C8 column under gradient condition. All 16 analytes were detected, quantified and confirmed using a triple quadrupole tandem mass spectrometry with selected reaction monitoring (SRM) in both negative and positive electrospray ionization modes. The limit of detection, quantification and confirmation of the analytes were 1.0 - 5.0 ng/mL, 1.0 - 5.0 ng/mL and 1.0 - 20 ng/mL, respectively. The linear dynamic range of quantification was 5.0 - 200 ng/mL. The method is routinely used in anti-doping analysis to control the abuse of NSAIDs in racehorses competing in PA.
文摘Background: Non-steroidal anti-inflammatory drugs (NSAIDs) are used for managing painful conditions. They are available as cheap, over-the-counter drugs, and commonly abused. NSAIDs inhibit prostaglandins (PGs) actions on the kidneys and can cause kidney disease and hypertension, especially when used in excess doses, for prolonged period or in stressed states. Methods: The descriptive study was carried at the Orthopaedic and Family Medicine units of the Federal Medical Centre, Abeokuta. Two hundred respondents participated in the study. One hundred frequent users of NSAIDs (with daily use for ≥ 4 weeks) and age and sex-matched controls with no known risk for kidney disease and had consented were consecutively recruited. Data were entered from history, examination and investigations (urinalysis, serum electrolyte, kidney scan and biopsy). Cases with estimated glomerular filtration rate (eGFR) 2) and dip strip proteinuria ≥ 1+ had kidney biopsy. Statistical analysis was with SPSS 21 software. Student t-test and Chi-square tests were used to compare means and proportions respectively. Pearson’s correlation test was used to determine the strength of association between independent risk factors and kidney dysfunction (KD). Results: Two hundred respondents participated in the study. Fifty one (51) females and Forty nine (49) males were recruited as cases and controls respectively. Thirteen (13) females had KD compared to 9 males, (P = 0.02). The mean age of cases with KD (63.04 yrs ± 4.21) was statistically higher than those without KD (P = 0.01). Majority of the cases were in the working population (30 - 59 yrs). Twenty two (22) frequent NSAIDs users had kidney dysfunction (KD) while six (6%) controls had KD. The proportion of subjects that used herbal medicines was higher in cases with KD than in cases without KD as well as in the controls respectively (P = 0.01). The mean kidney length and cortical thickness were significantly lower in cases with KD than in cases without KD, (P = 0.03) and (P = 0.017) respectively. The independent predictors of KD were increasing age, use of herbal remedies and duration of drug use. Conclusion: The prevalence of KD among frequent NSAIDs users was 22%, higher than controls. Risk factors identified include increasing age, use of herbal medicines, increasing body mass index (BMI), systolic blood pressure (SBP), anaemia, reduced cortical thickness and kidney volume. NSAIDs use in excess doses, prolonged period or in stressed state increases the risk for kidney dysfunction, caution is therefore needed to avoid taking these drugs in these conditions.
文摘Since the discovery of Helicobacter pylori(H.pylori)infection in the stomach,the bacteria infection and non-steroidal anti-inflammatory drugs(NSAIDs)use had been considered to be the 2 main causes of peptic ulcers.However,there have been recent reports of an increase in the proportion of peptic ulcers without these known risk factors;these are termed idiopathic peptic ulcers.Such trend was firstly indicated in 1990s from some reports in North America.In Asia,numerous studies reported that idiopathic ulcers accounted for a small percentage of all ulcers in the 1990s,but in the2000s,multiple studies reported that the proportion of idiopathic ulcers had reached 10%-30%,indicating that the incidence of idiopathic ulcers in Asia has also been rising in recent years.While a decline in H.pylori infection rates of general population in Asia is seen as the main reason for the increased incidence of idiopathic ulcers,it is also possible that the absolute number of idiopathic ulcer cases has increased.Advanced age,serious systemic complication,and psychological stress are considered to be the potential risk factors for idiopathic ulcers.Management of idiopathic ulcers is challenging,at present,because there is no effective preventative measure against recurrence in contrast with cases of H.pylori-positive ulcers and NSAIDs-induced ulcers.As it is expected that H.pylori infection rates in Asia will decline further in the future,measures to treat idiopathic ulcers will also likely become more important.

文摘AIM: To investigate the effect of a fat rich diet onnon-steroidal anti-inflammatory drug(NSAID)-induced mucosal damage in the murine small intestine.METHODS: C57BL6 mice were fed 4 types of diets with or without indomethacin.One group was fed standard laboratory chow.The other groups were fed a fat diet consisting of 8% w/w fat,beef tallow(rich in SFA),fish oil,(rich in omega-3 PUFA),or safflower oil(rich in omega-6 PUFA).Indomethacin(3 mg/kg) was injected intraperitoneally from day 8 to day 10.On day 11,intestines and adhesions to submucosal microvessels were examined.RESULTS: In the indomethacin-treated groups,mucosal damage was exacerbated by diets containing beef tallow and fish oil,and was accompanied by leukocyte infiltration(P < 0.05).The mucosal damage induced by indomethacin was significantly lower in mice fed the safflower oil diet than in mice fed the beef tallow or fish oil diet(P < 0.05).Indomethacin increased monocyte and platelet migration to the intestinal mucosa,whereas safflower oil significantly decreased monocyte and platelet recruitment(P < 0.05).CONCLUSION: A diet rich in SFA and omega-3 PUFA exacerbated NSAID-induced small intestinal damage via increased leukocyte infiltration.Importantly,a diet rich in omega-6-PUFA did not aggravate inflammation as monocyte migration was blocked.
文摘This editorial explores the impact of non-steroidal anti-inflammatory drugs(NSAIDs)on postoperative recovery in hand fracture patients,amidst shifting pain management strategies away from opioids due to their adverse effects.With hand fractures being significantly common and postoperative pain management crucial for recovery,the potential of NSAIDs offers a non-addictive pain control alternative.However,the controversy over NSAIDs'effects on bone healing—stemming from their Cyclooxygenase-2 inhibition and associated risks of fracture non-union or delayed union—necessitates further investigation.Despite a comprehensive literature search,the study finds a lack of specific research on NSAIDs in postoperative hand fracture management,highlighting an urgent need for future studies to balance their benefits against possible risks.
