    Inflammatory bowel disease(IBD) is composed of Crohn’s disease and ulcerative colitis and is manifested by both bowel-related and extraintestinal manifestations. Recently the number of therapeutic options available to treat IBD has dramatically increased, with each new medication having its own mechanism of action and side effect profile. A complete understanding of the hepatotoxicity of these medications is important in order to distinguish these complications from the hepatic manifestations of IBD. This review seeks to evaluate the hepatobiliary complications of non-steroid based IBD medications and aide providers in the recognition and management of these side-effects.

    Selective antagonists of the glucocorticoid receptor (GR) are desirable for the treatment of hypercortisolemia associated with Cushing's syndrome, psychic depression, obesity, diabetes, neurodegenerative diseases, and glaucoma. NC3327, a non-steroidal small molecule with potent binding affinity to GR (K{sub i} = 13.2 nM), was identified in a high-throughput screening effort. As a full GR antagonist, NC3327 greatly inhibits the dexamethasone (Dex) induction of marker genes involved in hepatic gluconeogenesis, but has a minimal effect on matrix metalloproteinase 9 (MMP-9), a GR responsive pro-inflammatory gene. Interestingly, the compound recruits neither coactivators nor corepressors to the GR complex but competes with glucocorticoids for the interaction between GR and a coactivator peptide. Moreover, NC3327 does not trigger GR nuclear translocation, but significantly blocks Dex-induced GR transportation to the nucleus, and thus appears to be a 'competitive' GR antagonist. Therefore, the non-steroidal compound, NC3327, may represent a new class of GR antagonists as potential therapeutics for a variety of cortisol-related endocrine disorders.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are frequently used to alleviate pain of the patients who suffer from inflammatory conditions like rheumatoid arthritis, osteoarthritis, and other painful conditions like gout. This class of drugs works by blocking cyclooxgenases which in turn block the prostaglandin production in the body. Most often, NSAIDs and antihypertensive drugs are used at the same time, and their use increases with increasing age. Moreover, hypertension and arthritis are common in the elderly patients requiring pharmacological managements. An ample amount of studies put forth evidence that NSAIDs reduce the efficiency of antihypertensive drugs plus aggravate pre-existing hypertension or make the individuals prone to develop high blood pressure through renal dysfunction. This review will help doctors to consider the effects and risk factors of concomitant prescription of NSAIDs and hypertensive drugs.

    Among the lesions of haematopoiesis conditioned by medicaments the lesions by non-steroidal antirheumatic drugs occupy the first place. They get their significance by the fact that they are not so infrequently irreparable and thus show an unfavourable prognosis. On principle in pathogenetic respect lesions by immunologic reactions which vastly do not depend on the dosage, are to be demarcated from the toxically conditioned side-effects which depend on dosage. Conditioned by drugs aplastic syndromes of the bone marrow are not in every case strongly depending on dosage. For this is to be assumed an individual, particular sensitivity of the haematopoietic stem cells (stem cell defect). Of the anti-rheumatic drugs used for the basic therapy chloroquine derivations, gold, D-penicillamine, immunosuppressives and levamisol may effect disturbances of the haematopoiesis, for which facts are examples are given. This concerns also the symptomatically acting antirheumatic drugs. An overestimation of rare side-effects of drugs should not block the application of certain medicaments, however, they should be given only in such a high dosage as it is necessary. In combinations of antirheumatic drugs every individual drug is considered as causative factor. Interactions are particularly be taken into consideration. Control programmes, particularly with certain laboratory parameters, give the early recognition of side-effects and render possible to avoid severe effects.

    Full Text Available Steroidal mineralocorticoid receptor antagonists (MRAs are effective in the treatment of kidney disease; however, the side effect of hyperkalaemia, particularly in the context of renal impairment, is a major limitation to their clinical use. Recently developed non-steroidal MRAs have distinct characteristics suggesting that they may be superior to steroidal MRAs. Therefore, we explored the benefits of a non-steroidal MRA in a model of rapidly progressive glomerulonephritis.Accelerated anti-glomerular basement membrane (GBM glomerulonephritis was induced in groups of C57BL/6J mice which received no treatment, vehicle or a non-steroidal MRA (BR-4628, 5mg/kg/bid from day 0 until being killed on day 15 of disease. Mice were examined for renal injury.Mice with anti-GBM glomerulonephritis which received no treatment or vehicle developed similar disease with severe albuminuria, impaired renal function, glomerular tuft damage and crescents in 40% of glomeruli. In comparison, mice which received BR-4628 displayed similar albuminuria, but had improved renal function, reduced severity of glomerular tuft lesions and a 50% reduction in crescents. The protection seen in BR-4628 treated mice was associated with a marked reduction in glomerular macrophages and T-cells and reduced kidney gene expression of proinflammatory (CCL2, TNF-α, IFN-γ and profibrotic molecules (collagen I, fibronectin. In addition, treatment with BR-4626 did not cause hyperkalaemia or increase urine Na+/K+ excretion (a marker of tubular dysfunction.The non-steroidal MRA (BR-4628 provided substantial suppression of mouse crescentic glomerulonephritis without causing tubular dysfunction. This finding warrants further investigation of non-steroidal MRAs as a therapy for inflammatory kidney diseases.

    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.

    Full Text Available Increasing evidence suggests that prostatic inflammation plays a key role in the development of prostate cancer. It remains controversial whether non-steroidal anti-inflammatory drugs (NSAIDs reduce the risk of prostate cancer. Here, we investigate how a previously reported inverse association between NSAID use and the risk of aggressive prostate cancer is modulated by variants in several inflammatory genes. We found that NSAIDs may have differential effects on prostate cancer development, depending on one’s genetic makeup. Further study of these inflammatory pathways may clarify the mechanisms through which NSAIDs impact prostate cancer risk.

    2006-01-01

    Non-steroidal anti-inflammatory drugs (NSAIDs)including cyclooxygenase 2 (COX-2) selective inhibitors,are potential agents for the chemoprevention of gastric cancer. Epidemiological and experimental studies have shown that NSAID use is associated with a reduced risk of gastric cancer although many questions remain unanswered such as the optimal dose and duration of treatment. The possible mechanisms for the suppressor effect of NSAIDs on carcinogenesis are the ability to induce apoptosis in epithelial cells and regulation of angiogenesis. Both COX-dependent and COX-independent pathways have a role in the biological activity of NSAIDs. Knowledge of how NSAIDs prevent neoplastic growth will greatly aid the design of better chemopreventive drugs and novel treatments for gastric cancer.

    Diclofenac, 2-[2-[(2,6-dichlorophenyl)amino]phenyl]acetic acid, is an important non-steroidal anti-inflammatory drug widely used for human and animals to reduce inflammation and pain. Diclofenac could potentially reach agricultural lands through the application of municipal biosolids or wastewater, and in the absence of any environmental fate data, we evaluated its persistence in agricultural soils incubated in the laboratory. {sup 14}C-Diclofenac was rapidly mineralized without a lag when added to soils varying widely in texture (sandy loam, loam, clay loam). Over a range of temperature and moisture conditions extractable {sup 14}C-diclofenac residues decreased with half lives < 5 days. No extractable transformation products were detectable by HPLC. Diclofenac mineralization in the loam soil was abolished by heat sterilization. Addition of biosolids to sterile or non-sterile soil did not accelerate the dissipation of diclofenac. These findings indicate that diclofenac is readily biodegradable in agricultural soils.

    The ability of different non-steroidal anti-inflammatory drugs (diclofenac, indomethacin, ketoprofen, naproxen and piroxicam) to inhibit gastric prostaglandin E2 production in the rat was compared with their damaging potential on gastric mucosa. The influence of treatment with zinc acexamate (ZAC) on these two parameters was also determined. ZAC treatment significantly decreased the degree of gastric damage elicited by all the antiinflammatories tested. The experimental data confirm the complexity of the gastrolesive effect exerted by anti-inflammatory drugs and that only part of such effect would be related with their inhibition of prostaglandin synthesis. These results indicate that the gastroprotection of ZAC does not exclusively depend on the effect on the synthesis of prostaglandins by the gastric mucosa, yet it can additionally be exerted through alternative mechanisms.

    The use of antithrombotic agents, particularly antiplatelet drugs like aspirin and clopidogrel, has been instrumental in decreasing the risk for adverse cardiovascular events across a wide range of patients. However, despite the established benefits, the use of these medications remains suboptimal. There is a high degree of inter-individual variation in response to these treatments, whereby patients experience occlusive thromboembolic events, in spite of maintaining an appropriate treatment regimen. This has lead to the notion of antithrombotic "resistance" or "poor responders", which has been a growing concern amongst clinicians and other healthcare providers. Compounding this matter even further, reports of increased cardiovascular risk associated with the use of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen and naproxen, have revealed additional and unforeseen contributors to myocardial infarction and stroke. With all medications, striking a balance between the potential risks and benefits seems more art than science at times. However, given their widespread use and critical cardiovascular implications, further emphasis has been placed on understanding factors influencing antithrombotic and NSAID therapies. A major aim in cardiovascular pharmacogenetics is the discovery of genetic biomarkers that will allow for prospective screening and individualized prediction of drug efficacy and adverse reactions for these medications (both alone and together) within the context of cardiovascular disease.

    AIM: To determine non-steroidal anti-inflammatory drug (NSAID) prescribing practices in a tertiary referral hospital. METHODS: A single time-point audit of drug kardexes and clinical notes of n = 388 patients on 2 July 2008 was carried out assessing demographics, gastrointestinal and coronary heart disease risk factors, renal function and co-prescribed medications. RESULTS: Fifty-seven of 388 (14.7%) hospital patients were on NSAIDs. Forty-nine were prescribed NSAID after admission. Nineteen (32.2%) were on regular NSAID (11\\/19 on PPI) and 38 patients were on PRN NSAID (12\\/38 on PPI). Seventeen of 49 patients were on other medications associated with gastrointestinal bleeding (10\\/17 were on PPI). Nineteen patients (33.3%) were >60 years. Eight patients had three or four risk factors for gastrointestinal bleeding; six were on PPI. Thirteen patients had two risks; 7 were on PPI. Six of 19 patients with one risk factor were on PPI. 40.3% had stage 2\\/3 chronic kidney disease. 35.1% had ischaemic heart disease. CONCLUSIONS: NSAIDs and PPIs are often prescribed inappropriately.

    Iontophoresis is an important approach to improve transdermal drug delivery. However, The transdermal enhancement mechanism of iontophoresis was not well known. The relationship between the physicochemical properties of drugs and the transdermal enhancement effect of iontophoresis was revealed in this study. Non-steroidal anti-inflammatory drugs (NSAIDs) were used as the models, including aspirin, ibuprofen and indomethacin. Their oil-water partition coefficients were measured. The carbomer-based hydrogels of them were prepared. Iontophoresis significantly enhanced in vitro transdermal delivery across the rat skins. Strong lipophilicity could lead to high permeation of drugs. However, the dissociation extent (indicated as pKa) of drugs was the key factor to determine the transdermal enhancement effect of iontophoresis. The more dissociation the drugs were, the higher the transdermal enhancement effect of iontophoresis. The drug-loaded hydrogels combined with iontophoresis improved the treatment of rat raw's inflammatory syndrome. Iontophoresis significantly improved the drugs penetrating into the hypodermis, dermis and epidermis, more deeply than the application of drugs alone according to the experimental result of 5-carboxylfluorescein hydrogels. Iontophoresis led to the unordered arrangement of skin intercellular lipids, the significantly increased flowability and loose stratum corneum structure. Iontophoresis is a promising approach to improve transdermal drug delivery with safety and high efficiency.

    AIM: To investigate the association between individual or combined use of non-steroidal anti-inflammatory drugs (NSAIDs) or statins and colorectal cancer risk. METHODS: In a population-based case-control study in women, we examined the association between NSAIDs and statin use and the risk of colorectal cancers. We further investigated whether the use of statins modifies the protective effect of NSAIDs. Female cases ( n = 669)of colorectal cancer aged 50-74 years were identified from a statewide registry in Wisconsin during 1999-2001. Community control women ( n = 1375) were randomly selected from lists of licensed drivers and Medicare beneficiaries. Medication use and risk factor information were gathered during a structured telephone interview. A multivariable logistic regression model was used to calculate odds ratio (OR) and 95% confidence interval (CI). RESULTS: Overall, NSAIDs users had a 30% reduction in risk of colorectal cancer (95% CI: 0.56-0.88). Statin use was not associated with colorectal cancer risk (OR = 1.17, 95% CI: 0.74-1.85), regardless of structural type (lipophilic or hydrophilic), duration of use, or recency. There was no evidence of an interaction between NSAIDs and statins and colorectal cancer risk ( P-interaction = 0.28). CONCLUSION: Although our results confirm the inverse association between NSAIDs use and colorectal cancer risk, they do not support a risk reduction in statin users, or an interaction effect of combined NSAIDs and statin use.

    Most age-related diseases and aging itself are associated with chronic inflammation. Thus pharmacological inhibition of inflammatory processes may be effective antiaging strategy. In this study we demonstrated that treatment of Drosophila melanogaster with 10 non-steroidal anti-inflammatory drugs (NSAIDs: CAY10404, aspirin, APHS, SC-560, NS-398, SC-58125, valeroyl salicylate, trans-resveratrol, valdecoxib, licofelone) leads to extension of lifespan, delays age-dependent decline of locomotor activity and increases stress resistance. The effect of the lifespan increase was associated with decrease of fecundity. Depending on the concentration, NSAIDs demonstrated both anti- and pro-oxidant properties in Drosophila tissues. However, we failed to identify clear correlation between antioxidant properties of NSAIDs and their pro-longevity effects. The lifespan extending effects of APHS, SC-58125, valeroyl salicylate, trans-resveratrol, valdecoxib, and licofelone were more pronounced in males, valdecoxib and aspirin - in females. We demonstrated that lifespan extension effect of NSAIDs was abolished in flies with defective genes involved in Pkh2-ypk1-lem3-tat2 pathway.

    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 the 2000s, 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.

    In recent years, research studies have increasingly focused on assessing the occurrence of active pharmaceutical ingredients (APIs) in ecosystems. However, much remains unknown concerning the potential effects on APIs on non-target organisms due to the complexity of the mode of action, reactivity and bioconcentration potential for each specific drug. The non-steroidal anti-inflammatory drug (NSAID) diclofenac (DCF) is one of the most frequently detected APIs in surface waters worldwide and has recently been included in the list of priority substances under the European Commission. In this study, mussels (Mytilus galloprovincialis) were exposed to an environmentally relevant nominal concentration of DCF (250 ng L(-1)) over 15 days. The responses of several biomarkers were assessed in the mussel tissues: condition index (CI); superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR) and phase II glutathione-S-transferase (GST) activities, lipid peroxidation levels (LPO) associated with oxidative stress, acetylcholinesterase (AChE) activity related to neurotoxic effects and vitellogenin-like proteins linked to endocrine disruption. This study demonstrated significant induction of SOD and GR activities in the gills in addition to high CAT activity and LPO levels in the digestive gland. Phase II GST remained unaltered in both tissues, while the up-regulation of the AChE activity was directly related to the vitellogenin-like protein levels in exposed females, indicating an alteration in the estrogenic activity, rather than a breakdown in cholinergic neurotransmission function. This study confirmed that DCF at a concentration often observed in surface water induces tissue-specific biomarker responses. Finally, this study also revealed the importance of a multi-biomarker approach when assessing the potentially deleterious effects in a species that may be vulnerable to the continuously discharge of APIs into the ecosystems; this approach provides crucial new

  19. Insulinotropic effect of the non-steroidal compound STX in pancreatic β-cells.

    Directory of Open Access Journals (Sweden)

    Full Text Available The non-steroidal compound STX modulates the hypothalamic control of core body temperature and energy homeostasis. The aim of this work was to study the potential effects of STX on pancreatic β-cell function. 1-10 nM STX produced an increase in glucose-induced insulin secretion in isolated islets from male mice, whereas it had no effect in islets from female mice. This insulinotropic effect of STX was abolished by the anti-estrogen ICI 182,780. STX increased intracellular calcium entry in both whole islets and isolated β-cells, and closed the K(ATP channel, suggesting a direct effect on β-cells. When intraperitoneal glucose tolerance test was performed, a single dose of 100 µg/kg body weight STX improved glucose sensitivity in males, yet it had a slight effect on females. In agreement with the effect on isolated islets, 100 µg/kg dose of STX enhanced the plasma insulin increase in response to a glucose load, while it did not in females. Long-term treatment (100 µg/kg, 6 days of male mice with STX did not alter body weight, fasting glucose, glucose sensitivity or islet insulin content. Ovariectomized females were insensitive to STX (100 µg/kg, after either an acute administration or a 6-day treatment. This long-term treatment was also ineffective in a mouse model of mild diabetes. Therefore, STX appears to have a gender-specific effect on blood glucose homeostasis, which is only manifested after an acute administration. The insulinotropic effect of STX in pancreatic β-cells is mediated by the closure of the K(ATP channel and the increase in intracellular calcium concentration. The in vivo improvement in glucose tolerance appears to be mostly due to the enhancement of insulin secretion from β-cells.

    AIM: To establish the prevalence of Helicobacter pylori (H. pylori ) infection in patients with a bleeding peptic ulcer after consumption of non-steroidal antiinflammatory drugs (NSAIDs). METHODS: A very early upper endoscopy was performed to find the source of upper gastrointestinal bleeding and to take biopsy specimens for analysis of H. pylori infection by the rapid urease (CLO) test, histological examination, and bacterial culture. IgG anti- CagA were also sought. The gold standard for identifying H. pylori infection was positive culture of biopsy specimens or contemporary positivity of the CLO test and the presence of H. pylori on tissue sections. RESULTS: Eighty patients, 61 males (76.3%), mean age 61.2 ± 15.9 years, were consecutively enrolled. Forty-seven (58.8%) patients occasionally consumed NSAIDs, while 33 (41.3%) were on chronic treatment with low-dose aspirin (LD ASA). Forty-four (55.0%) patients were considered infected by H. pylori . The infection rate was not different between patients who occasionally or chronically consumed NSAIDs. The culture of biopsy specimens had a sensitivity of 86.4% and a specificity of 100%; corresponding figures for histological analysis were 65.9% and 77.8%, for the CLO test were 68.2% and 75%, for the combined use of histology and the CLO test were 56.8% and 100%, and for IgG anti-CagA were 90% and 98%. The highest accuracy (92.5%) was obtained with the culture of biopsy specimens. CONCLUSION: Patients with a bleeding peptic ulcer after NSAID/LD ASA consumption frequently have H. pylori infection. Biopsy specimen culture after an early upper gastrointestinal tract endoscopy seems the most efficient test to detect this infection.

    The enzyme 5 alpha-reductase (5 alpha R) catalyses the reduction of testosterone (T) into the more potent androgen dihydrotestosterone (DHT). The abnormal production of DHT is associated to pathologies of the main target organs of this hormone: the prostate and the skin. Benign prostatic hyperplasia (BPH), prostate cancer, acne, androgenetic alopecia in men, and hirsutism in women appear related to the DHT production. Two isozymes of 5 alpha-reductase have been cloned, expressed and characterized (5 alpha R-1 and 5 alpha R-2). They share a poor homology, have different chromosomal localization, enzyme kinetic parameters, and tissue expression patterns. Since 5 alpha R-1 and 5 alpha R-2 are differently distributed in the androgen target organs, a different involvement of the two isozymes in the pathogenesis of prostate and skin disorders can be hypothesized. High interest has been paid to the synthesis of inhibitors of 5 alpha-reductase for the treatment of DHT related pathologies, and the selective inhibition of any single isozyme represents a great challenge for medical and pharmaceutical research in order to have more specific drugs. At present, no 5 alpha R-1 inhibitor is marketed for the treatment of 5 alpha R-1 related pathologies but pharmaceutical research is very active in this field. This paper will review the major classes of 5 alpha R inhibitors focusing in particular on non-steroidal inhibitors and on structural features that enhance the selectivity versus the type 1 isozyme. Biological tests to assess the inhibitory activity towards the two 5 alpha R isozymes will be also discussed.

    A modified Quick, Easy, Cheap, Effective, Rugged and Safe (QuEChERS) method based on the dispersive solid-phase extraction (dSPE) combined with high performance liquid chromatography (HPLC) was developed for the determination of non-steroidal estrogens in water samples. In this study, graphene oxide-based silica microspheres (SiO2@GO) were used as dSPE material for the preconcentration of analytes. HPLC was used for the separation and detection. This was the first time that the synthesized SiO2@GO microspheres were used as stationary phases for the off-line preconcentration of the non-steroidal estrogens in dSPE. dSPE parameters, such as sample pH, volume and type of eluent were optimized. Application of the developed method to analyze spiked lake, reservoir and tap water samples resulted in good recoveries values ranging from 70 to 106% with relative standard deviation values lower than 7.0% in all cases. Limits of detection were in the range of 0.2-6.1 μg/L. The combined data obtained in this study recommended that the proposed method is very fast, simple, repeatable and accurate for the detection of non-steroidal estrogens. Furthermore, the SiO2@GO microspheres application could potentially be expanded to extract and pre-concentrate other compounds in various matrices.

    Among their beneficial effects, non-steroidal anti-inflammatory drugs may also exert several side effects which depend on the dosage and the type of these medications. The most frequent gastrointestinal side effects usually develop shortly after the beginning of their administration, but others such as cardiovascular interactions (which are present much less frequently than gastrointestinal side effects) can also occur after the beginning of drug administration without a latency period. For a long-term treatment, non-steroidal anti-inflammatory drugs are most frequently used in the elderly population where patients typically have high cardiovascular risk and take other medicines, e.g. low dose acetylsalicylic acid that can interact with non-steroidal anti-inflammatory drugs; in this aspect diclofenac may cause less side effects. In this review, the authors briefly review cardiovascular side effects of non-steroidal anti-inflammatory drugs, the processes which potentially influence them, therapeutic consequences and their interaction with acetylsalicylic acid.

They remain a key component of the pharmacological management of acute and chronic pain. The COX-1 and COX-2 isozymes have different biological functions; analgesic activity is primarily (although not exclusively associated with inhibition of COX-2, while different side effects result from the inhibition of COX-1 and COX-2. All available NSAIDs, including acetaminophen and aspirin, are associated with potential side effects, particularly gastrointestinal and cardiovascular effects, related to their relative selectivity for COX-1 and COX-2. Since all NSAIDs exert their therapeutic activity through inhibition of the COX isozymes, strategies are needed to reduce the risks associated with NSAIDs while achieving sufficient pain relief. A better understanding of the inhibitory activity and COX-1/COX-2 selectivity of an NSAID at therapeutic doses, based on pharmacokinetic and pharmacodynamic properties (eg, inhibitory dose, absorption, plasma versus tissue distribution, and elimination, and the impact on drug tolerability and safety can guide the selection of appropriate NSAIDs for pain management. For example, many NSAIDs with moderate to high selectivity for COX-2 versus COX-1 can be administered at doses that maximize efficacy (~80% inhibition of COX-2 while minimizing COX-1 inhibition and associated side effects, such as gastrointestinal toxicity. Acidic NSAIDs with favorable tissue distribution and short plasma half-lives can additionally be dosed to provide near-constant analgesia while

    Methotrexate (MTX) is used not only for the cancer chemotherapy but also for the treatment of rheumatic disease, often together with non-steroidal anti-inflammatory drugs (NSAIDs). MTX is actively cotransported with H(+) in the small intestine, mediated by a reduced folate carrier (RFC). The coadministration of some NSAIDs with MTX to rats caused a decrease of MTX absorption through the small intestine. This may be due to the uncoupling effect of oxidative phosphorylation of the NSAIDs. The present study investigated whether flufenamic acid, diclofenac and indomethacin, NSAIDs, decreased ATP content of rat-derived intestinal epithelial cell line IEC-6 cells and affected the MTX transport in IEC-6 cells. The MTX uptake in IEC-6 cells was dependent on medium pH and maximum around pH 4.5-5.5. The MTX uptake was composed of a transport inhibited by 4, 4'-diisothiocyanostilbene-2, 2'-disulfonic acid (DIDS) and a non-saturable one. The DIDS-sensitive component in the MTX uptake showed a saturation kinetics (Michaelis-Menten constant (Km): 3.91 +/- 0.52 microM, Maximum velocity (Vmax): 94.66 +/- 6.56 pmol/mg protein/5 min). The cellular ATP content in IEC-6 cells decreased significantly at 30 min after the cells were started to incubate with the NSAIDs (250 microM flufenamic acid, 500 microM diclofenac and 500 microM indomethacin). The MTX uptake in IEC-6 cells in the presence of the NSAIDs decreased with the reduction of cellular ATP content and showed a good correlation with the ATP content (correlation coefficient: 0.982). Thus it seems likely that the ATP content in IEC-6 cells with the NSAIDs decreased due to the uncoupling effect of oxidative phosphorylation of the NSAIDs, resulting in the inhibition of the secondary active transport of MTX in IEC-6 cells. The present results also suggest that IEC-6 cells are useful to evaluate the drug interaction relating to this carrier system.

    Full Text Available The present prospective study was conducted in order to establish the drug-prescription trend of non-steroidal antiinflammatory drugs in the management pattern of osteoarthritis at Panjab University Health Centre, Chandigarh, India. The study was carried out in between the months of November 2003 and March 2004. Data was collected from outpatients who visited Panjab University Health Centre. WHO based prescription-auditing performa was used for data collection. Demographic analysis of this prospective and observational study revealed that out of 84 patients most were females (63.1% and maximum patients were in the age group of 40-60 (59.5%. Most of the patients at Panjab University Health Centre had primary generalized Osteoarthritis with the back (50% being the site most commonly affected followed by knee (45.23% and hips (14.3%. Pain and joint stiffness was the common feature of the clinical presentation. Non-Steroidal Antiinflammatory Drugs were mostly prescribed during the observation period predominantly for pain relief. The most commonly prescribed agents were nimesulide, paracetamol, diclofenac and ibuprofen. Mostly the drugs were administered in the tablet form (86.05% with least use of gels/creams and capsules. The use of non-drug therapies including physiotherapy and exercise was least found. The present study represents the current prescribing trend of non-steroidal antiinflammatory drugs for osteoarthritis at Panjab University Health Centre and it also suggested that there is still considerable scope for improvement, particularly in prescribing non-drug therapies and improving dispensing habits.

    Inheritance of a gene mutation leads to the initiation of 5 to 10% of most cancers, including colon cancer cases. We developed a chemoprevention strategy using a novel combination of the non-steroidal anti-inflammatory (NSAID) sulindac plus the anthelminthic benzimidazole, mebendazole. This oral drug combination was effective in the ApcMin/+ mouse model of Familial Adenomatous Polyposis (FAP). Treatment with 35 mg/kg daily mebendazole reduced the number of intestinal adenomas by 56% (P = 0.0002), 160 ppm sulindac by 74% (P cancer patients using mebendazole either alone or in combination. The findings have implications for populations with moderate and above risk for developing cancer.

    Non-steroidal anti-inlfammatory drugs (NSAIDs) were able to produce tissue damage and oxidative stress in animal models of small intestinal damage. In this study, the putative protective effect of wheat peptides was evaluated in a NSAID-induced small intestinal damage model in rats, different doses of wheat peptides or distilled water were administered daily by intragastric administration for 30 d until small intestinal damage was caused. Before sacriifcing, NSAIDs (aspirin and indomethacin) or physiological saline were infused into the digestive tract twice. Wheat peptides administration reduced edema and small intestinal damage, and signiifcantly decreased the level of tumor necrosis factor (TNF)-α in mucous membrane of small intestine. Oxidative stress was signiifcantly increased after NSAID infusion and was reduced by wheat peptides. Wheat peptides increased glutathione peroxidase(GSH-Px) activity in mucous membrane of small intestine. µ-Opioid receptor mRNA expression decreased more signiifcantly in wheat peptides treated rats than in the model control group. Overall, the results suggest that non-steroidal anti-inlfammatory drugs induced small intestinal damage in rats and wheat peptides administration may be an effective tool for protecting small intestinal tissue against NSAID-induced small intestinal damage and oxidative stress.

    The cooperation of adaptive immunity with pharmacologic therapy influences cancer progression. Though non-steroidal anti-inflammatory drugs (NSAIDs) have a long history of cancer prevention, it is unclear whether adaptive immune system affects the action of those drugs. In present study, we revealed a novel immunological mechanism of sulindac. Our data showed that sulindac had substantial efficacy as a single agent against 4T1 murine breast cancer and prolonged the survival of tumor-bearing mice. However, in the athymic nude mice, sulindac treatment was ineffective. Further in vivo T cell subsets depletion experiments showed that CD8+ T lymphocytes deficiency reversed the anti-tumor effect of sulindac. In addition, sulindac significantly reduced M2 macrophages recruitment, cancer-related inflammation and tumor angiogenesis. Our results advance our understanding of the mechanisms of NSAIDs, and more importantly, this will provide insight into rational drug design or antitumor immunotherapy.

    2008-06-01

    In this contribution, we report on fast and ultrafast dynamics of a non-steroidal anti-inflammatory drug, piroxicam (PX), in methyl acetate (MAC) and triacetin (TAC), two solvents of different viscosities. The enol form of PX undergoes a femtosecond (shorter than 100 fs) electronically excited state intramolecular proton-transfer reaction to produce keto tautomers. These structures exhibit an internal twisting motion to generate keto rotamers in ˜2-5 ps, a time being longer in TAC. The transient absorption/emission spectrum is very broad indicating that the potential-energy surface at the electronically excited state is very flat, and reflecting the involvement of several coordinates along which the wavepacket of the fs-produced structures evolve.

    The protein binding of non-steroidal anti-inflammatory drugs flurbiprofen, ketoprofen and etodolac with human serum albumin (HSA) was investigated using indirect chiral high performance liquid chromatography (HPLC) and ultrafiltration techniques. S-(-)-1-(1-naphthyl)- ethylamine (S-NEA) was utilized as chiral derivatization reagent and pre-column derivatization RP-HPLC method was established for the separation and assay of the three pairs of enantiomer. The method had good linear relationship over the investigated concentration range without interference. The average extraction efficiency was higher than 85% in different systems, and the intra-day and inter-day precisions were less than 15%. In serum albumin, the protein binding of etodolac enantiomers showed significant stereoselectivity that the affinity of S-enantiomer was stronger than R-enantiomer, and the stereoselectivity ratio reached 6.06; Flurbiprofen had only weak stereoselectivity in HSA, and ketoprofen had no stereoselectivity at all. Scatchard curves showed that all the three chiral drugs had two types of binding sites in HSA.

    There is evidence that aspirin and non-aspirin non-steroidal anti-inflammatory drug (NSAID) have anti-carcinogenic properties, but their effect on lung cancer, in particular in never-smokers, is unclear. Information on past or current use of anti-inflammatory medication was obtained in 398 Chinese female primary lung cancer cases and 814 controls in a hospital-based study in Singapore. 65% of cases and 88% of controls were never-smokers. Controls were excluded if they had been admitted for conditions associated with aspirin or NSAID use (n=174). Regular aspirin use (twice a week or more, for a month or more) was associated with a reduced risk of lung cancer (adjusted odds ratio [OR] 0.50, 95% confidence intervals [95%CI] 0.31-0.81 in non-smokers; OR 0.38, 95%CI 0.16-0.93 in smokers). Regular use of non-aspirin NSAID, paracetamol, steroid creams and steroid pills was uncommon and no association with lung cancer was detected. Our results suggest that aspirin consumption may reduce lung cancer risk in Asian women and are consistent with current understanding of the role of cyclooxygenase in lung carcinogenesis.

    Nabumetone is a non-steroidal anti-inflammatory drug (NSAID). It works as a prodrug and is extensively metabolized to an active metabolite, 6-methoxy-2-naphthylacetic acid (6MNA). It is well known that neutrophil infiltration and activation are critical in the pathogenesis of NSAID-induced gastric injury, and nabumetone shows less incidence of gastrointestinal irritancy. We examined the effects of nabumetone on neutrophil activation and on indometacin-induced gastric damage. In the indometacin-induced gastric mucosal injury, rats were treated with indometacin and then nabumetone or 6MNA was orally administered. Nabumetone prevented gastric damage accompanied by the reduction of neutrophil infiltration into gastric mucosa, but such an effect was not observed with 6MNA. Nabumetone reduced the formyl methionyl leucyl phenylalanine (fMLP)-induced respiratory burst of human neutrophils to 30% of the control level in-vitro, but 6MNA did not. In addition, nabumetone prevented the fMLP-induced migration of neutrophils. Nabumetone did not inhibit O2- generation in the xanthine-xanthine oxidase system. These results suggest that nabumetone prevents gastric damage induced by the active metabolite, 6MNA, via the suppression of neutrophil activation in gastric mucosa.

    Purpose The aim of this study is to explore non-steroid anti-inflammation drugs (NSAIDs) potency for pelvic floor muscle pain by measuring local concentration in a rat model. Materials and Methods We used nine NSAIDs, including nabumetone, naproxen, ibuprofen, meloxicam, piroxicam, diclofenac potassium, etodolac, indomethacin, and sulindac, and 9 groups of female Wister rats. Each group of rats was fed with one kind of NSAID (2 mg/mL) for three consecutive days. Thereafter, one mL of blood and one gram of pelvic floor muscle were taken to measure drug pharmacokinetics, including partition coefficient, lipophilicity, elimination of half-life (T1/2) and muscle/plasma converting ratio (Css, muscle/Css, plasma). Results Diclofenac potassium had the lowest T1/2 and the highest mean Css, muscle/Css, plasma (1.9 hours and 0.85±0.53, respectively). The mean Css, muscle/Css, plasma of sulindac, naproxen and ibuprofen were lower than other experimental NSAIDs. Conclusion Diclofenac potassium had the highest disposition in pelvic floor muscle in a rat model. The finding implies that diclofenac potassium might be the choice for pain relief in pelvic muscle.

    Use of non-steroidal anti-inflammatory drugs (NSAIDs) for chemoprevention of colon cancer has been hindered by their potential gastro-intestinal toxicity. Nabumetone, which is approximately 10 to 36 times safer than conventional NSAIDs, was evaluated in 2 models of experimental colon carcinogenesis. In azoxymethane (AOM)-treated Fisher 344 rats, nabumetone caused dose-dependent inhibition of aberrant crypt foci (ACF), with 750 and 1,500 ppm resulting in 15% and 37% reductions, respectively (p nabumetone, with 900 ppm suppressing approximately half of the intestinal tumors. Interestingly, inhibition of intermediate biomarkers in both models was markedly greater in the distal than the proximal bowel. To mechanistically evaluate this regional selectivity, we assessed cyclo-oxygenase-2 (COX-2) expression in the uninvolved mucosa and demonstrated a 3- to 4-fold excess in the distal relative to the proximal bowel in both MIN mice and AOM-treated rats. We then investigated another putative NSAID target, peroxisome proliferator-activated receptor-delta (PPAR-delta) and demonstrated up-regulation during AOM-induced colonic tumorigenesis. Furthermore, in pre-neoplastic mucosa, there was a 3-fold excess of PPAR-delta in the distal colon. We demonstrate that nabumetone is an effective protective agent in both experimental models of colon carcinogenesis. The striking distal predilection of nabumetone may be, at least partially, explained by distal bowel over-expression of COX-2 and PPAR-delta.

    Pain associated with poultry lameness is poorly understood. The anti-nociceptive properties of two non-steroidal anti-inflammatory drugs (NSAIDs) were evaluated using threshold testing in combination with an acute inflammatory arthropathy model. Broilers were tested in six groups (n=8 per group). Each group underwent a treatment (saline, meloxicam (3 or 5mg/kg) or carprofen (15 or 25mg/kg)) and a procedure (Induced (arthropathy-induction) or sham (sham-handling)) prior to testing. Induced groups had Freund's complete adjuvant injected intra-articularly into the left intertarsal joint (hock). A ramped thermal stimulus (1°C/s) was applied to the skin of the left metatarsal. Data were analysed using random-intercept multi-level models. Saline-induced birds had a significantly higher skin temperature (± SD) than saline-sham birds (37.6 ± 0.8°C vs. 36.5 ± 0.5°C; Z=-3.47, Pnociception). Quantification of nociceptive responsiveness in a predictable broiler pain model identified thermal anti-hyperalgesic properties of two NSAIDs, which suggested that therapeutically effective treatment was provided at the doses administered. Such validation of analgesic strategies will increase the understanding of pain associated with specific natural broiler lameness types.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are emerging as novel chemopreventive agents against a variety of cancers owing to their capability in blocking the tumor development by cellular proliferation and by promoting apoptosis. Inflammation is principal cause of colon carcinogenesis. A missing link between inflammation and cancer could be the activation of NF-κB, which is a hallmark of inflammatory response, and is commonly detected in malignant tumors. Therefore, targeting pro-inflammatory cyclooxygenase enzymes and transcription factors will be profitable as a mechanism to inhibit tumor growth. In the present study, we have studied the role of various pro-inflammatory enzymes and transcription factors in the development of the 1,2-dimethylhydrazine dihydrochloride (DMH)-induced colorectal cancer and also observed the role of three NSAIDs, viz., Celecoxib, Etoricoxib and Diclofenac. Carcinogenic changes were observed in morphological and histopathological studies, whereas protein regulations of various biomolecules were identified by immunofluorescence analysis. Apoptotic studies was done by TUNEL assay and Hoechst/PI co-staining of the isolated colonocytes. It was found that DMH-treated animals were having an over-expression of pro-inflammatory enzymes, aberrant nuclear localization of activated cell survival transcription factor, NF-κB and suppression of anti-inflammatory transcription factor PPAR-γ, thereby suggesting a marked role of inflammation in the tumor progression. However, co-administration of NSAIDs has significantly reduced the inflammatory potential of the growing neoplasm.

    This paper reports the facile synthesis, characterization and solar-light driven photocatalytic degradation of TiO2 quantum dots (QDs). The TiO2 QDs were synthesized by a facile ultrasonic-assisted hydrothermal process and characterized in terms of their structural, morphological, optical and photocatalytic properties. The detailed studies confirmed that the prepared QDs are well-crystalline, grown in high density and exhibiting good optical properties. Further, the prepared QDs were efficiently used as effective photocatalyst for the sun-light driven photocatalytic degradation of ketorolac tromethamine, a well-known non-steroidal anti-inflammatory drug (NSAID). To optimize the photocatalytic degradation conditions, various dose-dependent, pH-dependent, and initial drug-concentration dependent experiments were performed. The detailed solar-light driven photocatalytic experiments revealed that ∼99% photodegradation of ketorolac tromethamine drug solution (10 mg L(-1)) was observed with optimized amount of TiO2 QDs and pH (0.5 g L(-1) and 4.4, respectively) under solar-light irradiations. The observed results demonstrate that simply synthesized TiO2 QDs can efficiently be used for the solar-light driven photocatalytic degradation of harmful drugs and chemicals.

    Fertility control is a burning problem all over the world to regulate population overflow and maintain ecological balance. This study is an in-silico approach to explore a non-steroidal lead as contraceptive agent in order to avoid several contraindications generated by steroidal analogues. Piperolactam A, an aristolactam isolated from Piper betle Linn. showed binding affinity towards estrogen and progesterone receptor as -8.9 and -9.0Kcal/mol (inhibition constant Ki=0.294μM and 0.249μM) respectively which is even larger than that of reported antagonists such as Rohitukine and OrgC (binding affinity -8.7 and -8.4Kcal/mol; Ki 0.443μM and 0.685μM respectively). The binding site exploration displayed more hydrogen bonding of Piperolactam A (His 524, Leu 346, Thr 347) than Rohitukine and OrgC (Leu 718) with associated receptors which was further confirmed by molecular dynamics simulations. The drug-likeliness of the compound has been proved from its tally with Lipinsky's Rule of Five and lowered toxicity such as cardiac toxicity, liver toxicity, mutagenicity and ecological toxicity. Endocrine disruptome and later docking guided molecular simulations revealed that Piperolactam A has weaker binding affinity and/or lower probability of binding with nuclear receptors especially hERG and cytochrome P450. The high Caco-2 permeability suggested more bioavailability hence more therapeutic efficacy of the drug.

    In equine medicine, stem cell therapies for orthopaedic diseases are routinely accompanied by application of NSAIDs (non-steroidal anti-inflammatory drugs). Thus, it has to be analysed how NSAIDs actually affect the growth and differentiation potential of MSCs (mesenchymal stem cells) in vitro in order to predict the influence of NSAIDs such as phenylbutazone, meloxicam, celecoxib and flunixin on MSCs after grafting in vivo. The effects of NSAIDs were evaluated regarding cell viability and proliferation. Additionally, the multilineage differentiation capacity and cell migration was analysed. NSAIDs at lower concentrations (0.1-1 μM for celecoxib and meloxicam and 10-50 μM for flunixin) exert a positive effect on cell proliferation and migration, while at higher concentrations (10-200 μM for celecoxib and meloxicam and 100-1000 μM for flunixin and phenylbutazone), there is rather a negative influence. While there is hardly any influence on the adipogenic as well as on the chondrogenic MSC differentiation, the osteogenic differentiation potential, as demonstrated with the von Kossa staining, is significantly disturbed. Thus, it can be concluded that the effects of NSAIDs on MSCs are largely dependent on the concentrations used. Additionally, for some differentiation lineages, also the choice of NSAID is critical.

    Charge transfer (CT) complexes of some non-steroidal anti-inflammatory drugs, naproxen and etodolac which are electron donors with some π-acceptors, such as tetracyanoethylene (TCNE), 2,3-dichloro-5,6-dicyano- p-benzoquinone (DDQ), p-chloranil ( p-CHL), have been investigated spectrophotometrically in chloroform at 21 °C. The coloured products are measured spectrophotometrically at different wavelength depending on the electronic transition between donors and acceptors. Beer's law is obeyed and colours were produced in non-aqueous media. All complexes were stable at least 2 h except for etodolac with DDQ stable for 5 min. The equilibrium constants of the CT complexes were determined by the Benesi-Hildebrand equation. The thermodynamic parameters Δ H, Δ S, Δ G° were calculated by Van't Hoff equation. Stochiometries of the complexes formed between donors and acceptors were defined by the Job's method of the continuous variation and found in 1:1 complexation with donor and acceptor at the maximum absorption bands in all cases.

  5. Bacterial microbiota profiling in gastritis without Helicobacter pylori infection or non-steroidal anti-inflammatory drug use.

    Directory of Open Access Journals (Sweden)

    Xiao-Xing Li

    Full Text Available Recent 16S ribosomal RNA gene (rRNA molecular profiling of the stomach mucosa revealed a surprising complexity of microbiota. Helicobacter pylori infection and non-steroidal anti-inflammatory drug (NSAID use are two main contributors to gastritis and peptic ulcer. However, little is known about the association between other members of the stomach microbiota and gastric diseases. In this study, cloning and sequencing of the 16S rRNA was used to profile the stomach microbiota from normal and gastritis patients. One hundred and thirty three phylotypes from eight bacterial phyla were identified. The stomach microbiota was found to be closely adhered to the mucosa. Eleven Streptococcus phylotypes were successfully cultivated from the biopsies. One to two genera represented a majority of clones within any of the identified phyla. We further developed two real-time quantitative PCR assays to quantify the relative abundance of the Firmicutes phylum and the Streptococcus genus. Significantly higher abundance of the Firmicutes phylum and the Streptococcus genus within the Firmicutes phylum was observed in patients with antral gastritis, compared with normal controls. This study suggests that the genus taxon level can largely represent much higher taxa such as the phylum. The clinical relevance and the mechanism underlying the altered microbiota composition in gastritis require further functional studies.

    Full Text Available Background: Non-steroidal anti-inflammatory drugs (NSAIDs are among the widely used drugs and are often used by pregnant women. However, they can have significant teratogenic effects. The aim of the study was to investigate pregnant women′s knowledge about NSAIDs use during pregnancy and their perception and consumption pattern. Materials and Methods: The study was a cross sectional study on women waiting for a consultation in the selected maternity hospitals in Addis Ababa, Ethiopia. The pregnant women were selected randomly and then interviewed by using standardized questionnaires. Result : A total of 224 pregnant women were involved in the study. Out of those, 203 (90.6% of them have taken NSAIDs since the beginning of their pregnancy. About 201 (89.7%, 198 (88.4% and 189 (84.4% of the pregnant women considered that ibuprofen, diclofenac and aspirin are not NSAIDs respectively. Regarding analgesic effect of NSAIDs, 97 (43.3% of the pregnant women believed that NSAIDs are effective for treating pain. Acetaminophen was considered as the most effective treatment for pain by 84 (37.50% of the patients. Conclusion: Acetaminophen is the most common analgesic that was taken by most pregnant women. The knowledge of pregnant women about NSAIDs is poor.

    The authors developed a mathematical model of arachidonic acid (AA) degradation to prostaglandins (PGs) and leukotrienes (LTs), which are implicated in the processes of inflammation and hypersensitivity to non-steroidal anti-inflammatory drugs (NSAIDs). The model focuses on two PGs (PGE2 and PGD2) and one LT (LTC4), their % increases and their ratios. Results are compared with experimental studies obtained from non-asthmatics (NAs), and asthmatics tolerant (ATA) or intolerant (AIA) to aspirin. Simulations are carried out for predefined model populations NA, ATA and three AIA, based on the differences of two enzymes, PG E synthase and/or LTC4-synthase in two states, that is, no-inflammation and inflammation. Their model reveals that the model population with concomitant malfunctions in both enzymes is the most sensitive to NSAIDs, since the duration and the capacity for bronchoconstriction risk are highest after simulated oral dosing of indomethacin. Furthermore, inflammation prolongs the duration of the bronchoconstriction risk in all AIA model populations, and the sensitivity analysis reveals multiple possible scenarios leading to hypersensitivity, especially if inflammatory processes affect the expression of multiple enzymes of the AA metabolic pathway. Their model estimates the expected fold-changes in enzyme activities and gives valuable information for further targeted transcriptomic/proteomic and metabolomic studies.

    The widely used non-steroidal anti-inflammatory drugs (NSAIDs) function mainly through inhibition of cyclooxygenases 1 and 2 (Cox-1 and Cox-2). Unlike Cox-1, Cox-2 is considered an inducible and pro-inflammatory enzyme. We previously reported that Cox-2 is upregulated in activated human B lymphocytes and using Cox-2 selective inhibitors that Cox-2 is required for optimal antibody synthesis. It is not known whether commonly used non-prescription and non-Cox-2 selective drugs also influence antibody synthesis. Herein, we tested a variety of Cox-1/Cox-2 non-selective NSAIDs, namely ibuprofen, tylenol, aspirin and naproxen and report that they blunt IgM and IgG synthesis in stimulated human peripheral blood mononuclear cells (PBMC). Ibuprofen had its most profound effects in inhibiting human PBMCs and purified B lymphocyte IgM and IgG synthesis when administered in the first few days after activation. As shown by viability assays, ibuprofen did not kill B cells. The implications of this research are that the use of widely available NSAIDs after infection or vaccination may lower host defense. This may be especially true for the elderly who respond poorly to vaccines and heavily use NSAIDs.

    Animal and pathological studies suggest that inflammation may contribute to amyotrophic lateral sclerosis (ALS) pathology and that non-steroidal anti-inflammatory drugs (NSAIDs) might be protective. However, there are no prospective data on the relation between NSAID use and ALS risk in humans. The relation between NSAID use and ALS risk was explored in five large prospective cohort studies (the Nurses' Health Study, the Health Professionals Follow-up Study, the Cancer Prevention Study II Nutrition Cohort, the Multiethnic Cohort Study, and the National Institutes of Health - AARP Diet and Health Study). Detailed NSAID information was sought from 780,000 participants, 708 of whom developed ALS during follow-up. Cox proportional hazards models were used within each cohort and cohort-specific estimates were pooled with random effects models. Results showed that neither non-aspirin NSAID use, nor aspirin use was associated with ALS risk overall. The multivariable, pooled relative risk was 0.96 (95% CI 0.76-1.22) among non-aspirin NSAID users compared with non-users. Duration of NSAID use in years and frequency of NSAID use were not associated with ALS risk overall. In conclusion, the results do not support an overall effect of NSAIDs on ALS risk, but because NSAIDs have heterogeneous effects, a role of individual compounds cannot be excluded.

    The optimal duration and dose of aspirin and non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) in the potential prevention of colorectal cancer (CRC) have not been established. We examined this issue in the Danish Diet, Cancer, and Health Study. Self-reported NSAID use at entry (January...... subjects, we identified 615 CRC cases during 1995-2006. Daily aspirin use at entry was associated with a decreased risk of CRC (RR, 0.73; 95% CI, 0.49-1.10). A similar risk reduction was seen among subjects with 10 or more prescriptions for aspirin or non-aspirin NSAIDs and five or more years of follow......-up. Most aspirin prescriptions were for 75-150 mg aspirin tablets. Among non-aspirin NSAID users, only those with body mass index (BMI) above 25 showed risk reductions [RR, 0.69 (0.47-1.03) for 10 or more prescriptions]. Long-term consistent use of aspirin or non-aspirin NSAIDs appears necessary to achieve...

    Effect of tolmetin sodium(Tol) on acute and subacute exudative inflammation was tested in experimental animals. Tol had a potent inhibitory activity (ED50 = 0.75 mg/kg, p.o.) on the increased vascular permeability induced by acetic acid in mice, and the potency was about 0.4 times that of indomethacin (Ind), and 6-93 times that of ibuprofen (Ibu), phenylbutazone(Phe) and aspirin(Asp). The inhibitory activity of Tol(ED50 = 18.2 mg/kg, p.o.) on UV-induced erythema in guinea pigs was about 0.3 times that of Ind. A recovery of the hind paw edema of rats, produced by a mixture of kaolin and carrageenin, was promoted by oral administration of Tol(2.5 approximately 20 mg/kg x 5/2 days). Tol(80 mg/kg/day, p.o.) showed a significant activity in inhibiting the exudation caused by croton oil in rats, and the activity was about 0.025 times that of Ind and greater than that of Ibu, Phe and Asp. Tol(100-800 microgram/ml) inhibited in a dose-dependent manner the phytohemagglutinin-induced blast transformation of cultured lymphocytes from rat thymus, as did salicylic acid. In vitro, Tol showed a potent activity similar to that of Ibu and Phe in preventing the denaturation of bovine serum albumin and the lysis of rat erythrocytes. From these results, it is suggested that Tol has a particularly potent inhibitory activity on acute exudative inflammation, and the mode of action may be attributed to a mechanism similar to that seen with other acidic non-steroidal anti-inflammatory drugs.

    According to a meta-analysis, H pylori and non-steroidal anti-inflammatory drugs (NSAID) independently and significantly increase the risk of gastroduodenal ulcer and ulcer bleeding. Their coincidence is frequent,demonstration of a possible relationship and consequent attitude is of important implications. But unfortunately,no consensus has been approved in the past years and their interactions are still controversial. H pylori and NSAID are known to share a number of pathogenic mechanisms, but there is no evidence for the significant synergic action between these two risk factors. Their relationship is independent, additive, synergistic or antagonistic without considering the influence of other factors because studies on this subject are different in almost all aspects of their methodology, including the definition of a NSAID user as well as the types,doses, duration and their indications for NSAID use,as well as their end-points, definition of dyspepsia and regimes used for eradication of H pylori. These might contribute to the conflicting results and opinions. H pylori infection in humans does not act synergistically with NSAID on ulcer healing, and there is no need to eradicate it. This notion is supported by the finding that the eradication of H pylori does not affect NSAIDinduced gastropathy treated with omeprazole and that H pylori infection induces a strong cyclooxygenase-2(COX-2) expression resulting in excessive biosynthesis of gastroprotective prostaglandin which in turn counteracts NSAID-induced gastropathy and heals the existing ulcer.Other investigators claimed that H pylori infection acts synergistically with NSAID on ulcer development, and H pylori should be eradicated, particularly at the start of long-term NSAID therapy. Eradication of H pylori prior to NSAID treatment does not appear to accelerate ulcer healing or to prevent recurrent ulcers in NSAID users.However, some recommendations can be drawn from the results of clinical trails.

    AIM: To summarize clinical, endoscopic, radiologic and pathologic ffeatures off special diaphragm-like strictures ffound in small bowel, with no patient use off non-steroidal anti-inflammatory drugs (NSAIDs). METHODS: From January 2000 to Ddecember 2009, 5 cases (2 men and 3 women, with a mean age of 41.6 years) were diagnosed as having diaphragm-like strictures off small bowel on imaging,operationand, operationandoperation and pathology. All the patients denied the use of NSAIDs. The clinical, endoscopic, radiologic and pathologic findings in these 5 patients were retrospectively reviewed from the hospital database. Images of capsule endoscopy (CE) and small bowel follow-through (SBFT) obtained in 3 and 3 patients, respectively, and images off double-balloon enteroscopy and computed tomography enterography (CTE) obtained in all 5 patients were available for review. RESULTS: All patients presented with long-term (2-16 years) symptoms of gastrointestinal bleeding and varying degrees of anemia. There was only one stricture in ffour cases and three lesions in one case, and all the lesions were located in the middle or distal segment off ileum. Circumferential stricture was shown in the small bowel in three cases in the CE image, but the capsule was retained in the small bowel of 2 patients. Routine abdomen computed tomography scan showed no other abnormal results except gallstones in one patient. The lesions were shown as circumfferential strictures accompanied by dilated small bowel loops in the small bowel on the images of CTE (in all 5 cases), SBFT (in 2 cases) and double-balloon enteroscopy (in all cases). On microscopy, a chronic infflammatory inffiltrate and circumferential diaphragm were found in all lesions. CONCLUSION: Ddiaphragm-like strictures off small bowel might be a special consequence off unclear damaging insults to the intestine, having similar clinical, endoscopic, radiologic and pathologic features.

    Pulmonary inflammation is an important therapeutic target in cystic fibrosis (CF) patients, aiming to limit and delay the lung damage. The purpose of the present research was to produce respirable engineered particles of ketoprofen lysinate, a non-steroidal anti-inflammatory drug able to fight lung inflammatory status by direct administration to the site of action. Micronized drug powders containing leucine as dispersibility enhancer were prepared by co-spray drying the active compound and the excipient from water or hydro-alcoholic feeds. Microparticles were fully characterized in terms of process yield, particle size distribution, morphology and drug content. The ability of the drug to reach the deepest airways after aerosolization of spray-dried formulations was evaluated by Andersen cascade impactor, using the monodose DPI as device. In order to investigate the behaviour of the drug once in contact with lung fluid, an artificial CF mucus was prepared. Drug permeation properties were evaluated interposing the mucus layer between the drug and a synthetic membrane mounted in Franz-type diffusion cells. Finally, the effect of the engineered particles on vitality of human airway epithelial cells of patients homozygous for ΔF 508 CF (CuFi1) was studied and compared to that of raw active compound. Results indicated that powders engineering changed the diameter and shape of the particles, making them suitable for inhalation. The mucus layer in the donor compartment of vertical diffusion cells slowed down drug dissolution and permeation, leucine having no influence. Cell proliferation studies evidenced that the spray drying process together with the addition of leucine reduced the cytotoxic effect of ketoprofen lysine salt as raw material, making the ketoprofen lysinate DPI a very promising product for the inflammation control in CF patients.

    Nabumetone, a newer non-steroidal anti-inflammatory drug (NSAID) which preferentially blocks cyclo-oxygenase-2 activity, may be less nephrotoxic than indomethacin. This study tested whether nabumetone has effects different from those of indomethacin on exercise-induced changes in renal function and the renin-aldosterone system. In a randomized fashion, ten subjects were studied after indomethacin (100 mg), nabumetone (1 g) or no medication (control) administered orally at 22.00 hours on the day before each study day, and again at 8.00 hours upon arrival at the laboratory. Renal function was studied at baseline, during graded 20-min exercise sessions at 25%, 50% and 75% of the maximal oxygen uptake rate, and subsequently during two 1-h recovery periods. Heart rate, arterial blood pressure, cardiac output and plasma catecholamines at rest and during exercise were not altered by indomethacin or nabumetone. Indomethacin decreased urinary rates of excretion of 6-oxo-prostaglandin F(1alpha) (6-oxo-PGF(1alpha)) and thromboxane B(2) in all study periods. Nabumetone decreased 6-oxo-PGF(1alpha) excretion during and after exercise. Excretion rates for PGE(2) did not change. Neither indomethacin nor nabumetone changed baseline values or exercise-induced decreases in renal plasma flow or glomerular filtration rate. Indomethacin, but not nabumetone, decreased sodium excretion, urine flow rate and free water clearance. The renal response to exercise, however, remained unchanged. In contrast with nabumatone, indomethacin decreased the plasma renin concentration. Thus, during exercise, nabumetone may decrease the excretion of 6-oxo-PGF(1alpha) by inhibition of cyclo-oxygenase-1 or by inhibition of specific exercise-induced activation of cyclo-oxygenase-2, or both. None of the drugs changed the renal response to exercise. Inhibition by indomethacin of angiotensin II and thromboxane A(2) synthesis may, during exercise, counterbalance renal vasoconstriction caused by blockade of

    AIM: The study was to screen the possible risk factors of adverse drug reaction (ADR) induced by non-steroidal anti-inflammatory drugs (NSAIDs) in Shanghai patients with arthropathy. METHODS: The subjects were randomly selected from a database of outpatients with arthropathy from 9 main hospitals in Shanghai. A door to door retrospective epidemiological survey was used to collect demographic information about the patients, both individual and familial. This included data on their medical histories, lifestyle and dietary habits, history of smoking and alcohol consumption, history of drug therapy, quality of life (QOL) prior to NSAIDs intake, history of NSAIDs therapy and its ADR events, etc. Descriptive statistical methods and univariate analysis were also used to identify possible risk factors for ADRs induced by NSAIDs. RESULTS: Of the 1002 patients surveyed, the average length of NSAIDs intake was 2 years. ADR incidence from different NSAIDs was high, in a range from 46.7 %-66.2 %.In general, the candidate risk factors for ADRs were different for each NSAID. Each of the candidate risk factors were defined and studied in order to evaluate its role in the determination of ADRs from NSAIDs. "Family history of ADRs caused by NSAIDs" was found to be a significant risk factor for the four commonly used NSAIDs:meloxicam, diclofenac, nimesulide, and nabumetone. CONCLUSION: A retrospective epidemiological survey was useful in detecting the risk factors for ADRs caused by NSAIDs. The study found that different NSAIDs might have different risk factors and that there is no single risk factor universally applicable to all NSAIDs.

    An accurate, simple, sensitive and selective micellar liquid chromatographic method has been developed for the simultaneous determination of caffeine (CAF) and two non-steroidal anti-inflammatory drugs, namely ibuprofen (IBU) and ketoprofen (KET). The chemometric approach was applied to the optimization of separation of the studied drugs. To optimize their separation, the effect of six experimental parameters on retention was investigated by means of multivariate analysis. Separation was conducted using an ODS C18 (150 × 4.6 mm i.d.) stainless steel column at ambient temperature with UV detection at 260 nm. A mobile phase composed of 40 mM sodium dodecyl sulphate (SDS), 10% 1-propanol and 0.3% tri-ethylamine in 0.02 M phosphoric acid adjusted to pH 3 has been used at a flow rate of 1 mL/min. Regression models were characterized by both descriptive and predictive ability (R(2) ≥ 97.9% and R(cv)(2) ≥ 96.2%) and allowed the chromatographic separation of the drugs with a good resolution and a total analysis time within 15 min. The calibration curves were rectilinear over the concentration ranges of 2.0-25.0, 1.5-15.0 and 1.0-10.0 µg/mL for IBU, KET and CAF, respectively, with detection limits of 1.2, 1.0 and 0.6 µg/mL, and quantification limits of 1.6, 1.2 and 0.8 µg/mL, respectively. The results obtained were in good agreement with those obtained by the comparison method.

  1. Combinatorial effect of non-steroidal anti-inflammatory drugs and NF-κB inhibitors in ovarian cancer therapy.

    Directory of Open Access Journals (Sweden)

    Luiz F Zerbini

    Full Text Available Several epidemiological studies have correlated the use of non-steroidal anti-inflammatory drugs (NSAID with reduced risk of ovarian cancer, the most lethal gynecological cancer, diagnosed usually in late stages of the disease. We have previously established that the pro-apoptotic cytokine melanoma differentiation associated gene-7/Interleukin-24 (mda-7/IL-24 is a crucial mediator of NSAID-induced apoptosis in prostate, breast, renal and stomach cancer cells. In this report we evaluated various structurally different NSAIDs for their efficacies to induce apoptosis and mda-7/IL-24 expression in ovarian cancer cells. While several NSAIDs induced apoptosis, Sulindac Sulfide and Diclofenac most potently induced apoptosis and reduced tumor growth. A combination of these agents results in a synergistic effect. Furthermore, mda-7/IL-24 induction by NSAIDs is essential for programmed cell death, since inhibition of mda-7/IL-24 by small interfering RNA abrogates apoptosis. mda-7/IL-24 activation leads to upregulation of growth arrest and DNA damage inducible (GADD 45 α and γ and JNK activation. The NF-κB family of transcription factors has been implicated in ovarian cancer development. We previously established NF-κB/IκB signaling as an essential step for cell survival in cancer cells and hypothesized that targeting NF-κB could potentiate NSAID-mediated apoptosis induction in ovarian cancer cells. Indeed, combining NSAID treatment with NF-κB inhibitors led to enhanced apoptosis induction. Our results indicate that inhibition of NF-κB in combination with activation of mda-7/IL-24 expression may lead to a new combinatorial therapy for ovarian cancer.

  2. Inhibition of Human Transthyretin Aggregation by Non-Steroidal Anti-Inflammatory Compounds: A Structural and Thermodynamic Analysis

    Luis Mauricio T. R. Lima

    2013-03-01

    Full Text Available Transthyretin (TTR is a homotetrameric protein that circulates in plasma and cerebral spinal fluid (CSF whose aggregation into amyloid fibrils has been associated with at least two different amyloid diseases: senile systemic amyloidosis (SSA and familial amyloid polyneuropathy (FAP. In SSA aggregates are composed of WT-TTR, while in FAP more than 100 already-described variants have been found in deposits. Until now, TTR-related diseases have been untreatable, although a new drug called Tafamidis has been approved only in Europe to specifically treat V30M patients. Thus, new strategies are still necessary to treat FAP caused by other variants of TTR. TTR has two channels in the dimer interface that bind to the hormone thyroxin and that have been used to accommodate anti-amyloidogenic compounds. These compounds stabilize the tetramers, rendering TTR less amyloidogenic. Here, we investigated the effects of three non-steroidal anti-inflammatory compounds—sulindac (SUL, indomethacin (IND and lumiracoxib (LUM—as tetramer stabilizers and aggregation inhibitors. WT-TTR and the very aggressive TTR variant L55P were used as models. These compounds were able to stabilize TTR against high hydrostatic pressure (HHP, increasing the ΔGf by several kcal. They were also effective in inhibiting WT-TTR and L55P acid- or HHP-induced aggregation; in particular, LUM and IND were very effective, inhibiting almost 100% of the aggregation of both proteins under certain conditions. The species formed when aggregation was performed in the presence of these compounds were much less toxic to cells in culture. The crystal structures of WT-TTR bound to the three compounds were solved at high resolution, allowing the identification of the relevant protein:drug interactions. We discuss here the ligand-binding features of LUM, IND and SUL to TTR, emphasizing the critical interactions that render the protein more stable and less amyloidogenic.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are the drugs most frequently involved in hypersensitivity drug reactions. Histamine is released in the allergic response to NSAIDs and is responsible for some of the clinical symptoms. The aim of this study is to analyze clinical association of functional polymorphisms in the genes coding for enzymes involved in histamine homeostasis with hypersensitivity response to NSAIDs. We studied a cohort of 442 unrelated Caucasian patients with hypersensitivity to NSAIDs. Patients who experienced three or more episodes with two or more different NSAIDs were included. If this requirement was not met diagnosis was established by challenge. A total of 414 healthy unrelated controls ethnically matched with patients and from the same geographic area were recruited. Analyses of the SNPs rs17740607, rs2073440, rs1801105, rs2052129, rs10156191, rs1049742 and rs1049793 in the HDC, HNMT and DAO genes were carried out by means of TaqMan assays. The detrimental DAO 16 Met allele (rs10156191), which causes decreased metabolic capacity, is overrepresented among patients with crossed-hypersensitivity to NSAIDs with an OR  = 1.7 (95% CI  = 1.3–2.1; Pc  = 0.0003) with a gene-dose effect (P = 0.0001). The association was replicated in two populations from different geographic areas (Pc  = 0.008 and Pc  = 0.004, respectively). Conclusions and implications The DAO polymorphism rs10156191 which causes impaired metabolism of circulating histamine is associated with the clinical response in crossed-hypersensitivity to NSAIDs and could be used as a biomarker of response.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed in pregnancy to treat fever, pain and inflammation. Indications for chronic use of these agents during pregnancy are inflammatory bowel or chronic rheumatic diseases. Since the seventies, NSAIDs have been used as effective tocolytic agents: indomethacin has been the reference drug, delaying delivery for at least 48 hours and up to 7-10 days. Additionally, self-medication with NSAIDs is practiced by pregnant women. NSAIDs given to pregnant women cross the placenta and may cause embryo-fetal and neonatal adverse effects, depending on the type of agent, the dose and duration of therapy, the period of gestation, and the time elapsed between maternal NSAID administration and delivery. These effects derive from the action mechanisms of NSAIDs (mainly inhibition of prostanoid activity) and from the physiological changes in drug pharmacokinetics occurring during pregnancy. Increased risks of miscarriage and malformations are associated with NSAID use in early pregnancy. Conversely, exposure to NSAIDs after 30 weeks' gestation is associated with an increased risk of premature closure of the fetal ductus arteriosus and oligohydramnios. Fetal and neonatal adverse effects affecting the brain, kidney, lung, skeleton, gastrointestinal tract and cardiovascular system have also been reported after prenatal exposure to NSAIDs. NSAIDs should be given in pregnancy only if the maternal benefits outweigh the potential fetal risks, at the lowest effective dose and for the shortest duration possible. This article discusses in detail the placental transfer and metabolism of NSAIDs, and the adverse impact of prenatal NSAID exposure on the offspring.

    Dynamics of clinical parameters and quality of life (QL) was evaluated in 281 patients with knee and hip osteoarthrosis (OA) during long-term treatment of different duration. The group was dominated by women (71%) aged 41-65 yr with grade I-III OA according to Kellgren. Patients of groups I and II received only non-steroidal anti-inflammatory drugs (diclofenac, nize), those of groups III-IV the same drugs in combination with structum, chondrolon, and zeel T respectively. Clinical parameters were assessed based on VAS at rest and in motion, Leken's indices, and WOMAC, QL from SF-36 questionnaire. Variable clinical course was recorded in patients treated with non-steroidal drugs alone that caused rapid improvement after the very first treatment sessions followed by deterioration of the patients' condition. Addition of structum resulted in marked optimization of clinical and QL parameters within 3 months after the onset of combined therapy. Similar effect was obtained using chondrolon and zeel T, but 2-3 clinical parameters and 3 QL parameters were not significantly different from the initial ones after 12 and 24 months of therapy. It is concluded that structum produced the best therapeutic effect followed by chondrolon and zeel T. Non-steroidal anti-inflammatory drugs had no beneficial action whatever in patients with OA.

    Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs are the most frequently used group of pharmaceuticals. The high consumption and the uncontrolled disposal of unused drugs into municipal waste or their deposit in landfills can result in an increased concentration of these compounds in soils. Moreover, these drugs can affect the microbial activity. However, there is a lack of knowledge about these effects or it is very limited. Therefore, the objective of this study was to compare the impact of selected commercially available NSAIDs, i.e. diclofenac (DCF, naproxen (NPX, ibuprofen (IBF and ketoprofen (KTP, applied at concentrations of 1 and 10 mg/kg soil, on the activity of soil microorganisms during the 90-day experiment. To ascertain this impact, substrate-induced respiration (SIR, soil enzyme activities, i.e. dehydrogenase (DHA, acid and alkaline phosphatases (PHOS-H and PHOS-OH and urease (URE as well as changes in the rates of nitrification and ammonification processes were determined. In addition, the number of culturable bacteria and fungi were enumerated. In general, the obtained data showed a significant stimulatory effect of NSAIDs on the microbial activity. Higher concentrations of NSAIDs caused a greater effect, which was observed for SIR, PHOS-H, PHOS-OH, URE, N-NO3- and N-NH4+, even during the whole incubation period. Moreover, the number of heterotrophic bacteria and fungi increased significantly during the experiment, which was probably a consequence of the evolution of specific microorganisms that were capable of degrading NSAIDs and used them as an additional source of carbon and energy. However, an inhibitory effect of NPX, IBF or KTP for SIR, DHA, on both phosphatases and culturable bacteria and fungi was observed at the beginning of the experiment. At lower concentrations of NSAIDs, in turn, the effects were negligible or transient. In conclusion, the application of NSAIDs altered the biochemical and microbial activity of soil

    A new series of Mn(II) coordination polymers, namely, [{Mn(L)(H2 O)2 }⋅2 Nap]∞ (CP1), [{Mn(L)(Ibu)2 (H2 O)2 }]∞ (CP2), [{Mn(L)(Flr)2 (H2 O)2 }]∞ (CP3), [{Mn(L)(Ind)2 (H2 O)2 }⋅H2 O]∞ (CP4), [{Mn2 (L)2 (μ-Flu)4 (H2 O)}⋅L]∞ (CP5), [{Mn2 (L)2 (μ-Tol)4 (H2 O)2 }]∞ (CP6) and [{Mn2 (L)2 (μ-Mef)4 (H2 O)2 }]∞ (CP7) (Nap=naproxen, Ibu=ibuprofen, Flr=flurbiprofen, Ind=indometacin, Flu=flufenamic acid, Tol=tolfenamic acid and Mef=mefenamic acid) derived from various non-steroidal anti-inflammatory drugs (NSAIDs) and the organic linker 1,2-bis(4-pyridyl)ethylene (L) have been synthesized with the aim of being used for cell imaging and drug delivery. Single-crystal X-ray diffraction (SXRD) studies revealed that the NSAID molecules were part of the coordination polymeric network either through coordination to the metal center (in the majority of the cases) or through hydrogen bonding. Remarkably, all the Mn(II) coordination polymers were found to be soluble in DMSO, thereby making them particularly suitable for the desired biological applications. Two of the coordination polymers (namely, CP1 and CP3) reported herein, were found to be photoluminescent both in the solid as well as in the solution state. Subsequent experiments (namely, MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), and PGE2 (prostaglandin E2 ) assays) established their biocompatibility and anti-inflammatory response. In vitro studies by using a macrophage cell line (i.e., RAW 264.7) revealed that both CP1 and CP3 were excellent cell imaging agents. Finally, biodegradability studies under simulated physiological conditions in phosphate-buffered saline (PBS) at pH 7.6 showed that slow and sustained release of the corresponding NSAID was indeed possible from both CP1 and CP3.

    Full Text Available Background/Aim. A high risk of bleeding in Helicobacter pylori (H.pylori-negative, non-steroidal anti-inflammatory drugs (NSAID-negative ulcers highlights the clinical importance of analysis of the changing trends of peptic ulcer disease. The aim of the study was to investigate the risk factors for ulcer bleeding in patients with non-H. pylori infection, and with no NSAIDs use. Methods. A prospective study included patients with endoscopically diagnosed ulcer disease. The patients were without H. pylori infection (verified by pathohistology and serology and without exposure to NSAIDs and proton pump inhibitors (PPI within 4 weeks before endoscopy. After endoscopy the patients were divided into 2 groups: the study group of 48 patients with bleeding ulcer and the control group of 47 patients with ulcer, but with no bleeding. Prior to endoscopy they had completed a questionnaire about demographics, risk factors and habits. The platelet function, von Willebrand factor (vWF and blood groups were determined. Histopathological analysis of biopsy samples were performed with a modified Sydney system. The influence of bile reflux was analyzed by Bile reflux index (BRI. Results. Age, gender, tobacco and alcohol use did not affect the bleeding rate. The risk of bleeding did not depend on concomitant diseases (p = 0.509 and exposure to stress (p = 0.944. Aspirin was used by 16/48 (33.3% patients with bleeding ulcer, as opposed to 7/47 (14.9% patients who did not bleed (p = 0.036. Abnormal platelet function had 12/48 (25.0% patients who bled, as opposed to 2/47 (4.3% patients who did not bleed (p = 0.004. Patients with BRI < 14 bled in 79.2%, and did not bleed in 57.4% of the cases (p = 0.023. There was no statistical difference between groups in regards to blood groups and range of vWF. Antrum atrophy was found in 14/48 (29.2% patients with bleeding ulcer and in only 5/47 (10.6% patients who had ulcer without bleeding (p = 0.024. Conclusion. Abnormal

    Full Text Available While the number of clinical experiments investigating the effects of non-steroid anti-inflammatory drugs (NSAIDs on the cardiovascular (CV events has significantly increased over the last two decades, basic research related to the mechanism by which NSAIDs cause CV dysfunction is limited. High variability in the clinical trials conducted (different populations, dosages, exposure and types of NSAIDs has led to results which are difficult to interpret and compare between studies. Are there some NSAIDs safer than other from the standpoint of CV risk? We have try to answer at some aspects of this question.

    Full Text Available BACKGROUND: Randomised trials have highlighted the cardiovascular risks of non-steroidal anti-inflammatory drugs (NSAIDs in high doses and sometimes atypical settings. Here, we provide estimates of the comparative risks with individual NSAIDs at typical doses in community settings. METHODS AND FINDINGS: We performed a systematic review of community-based controlled observational studies. We conducted comprehensive literature searches, extracted adjusted relative risk (RR estimates, and pooled the estimates for major cardiovascular events associated with use of individual NSAIDs, in different doses, and in populations with low and high background risks of cardiovascular events. We also compared individual drugs in pair-wise (within study analyses, generating ratios of RRs (RRRs. Thirty case-control studies included 184,946 cardiovascular events, and 21 cohort studies described outcomes in >2.7 million exposed individuals. Of the extensively studied drugs (ten or more studies, the highest overall risks were seen with rofecoxib, 1.45 (95% CI 1.33, 1.59, and diclofenac, 1.40 (1.27, 1.55, and the lowest with ibuprofen, 1.18 (1.11, 1.25, and naproxen, 1.09 (1.02, 1.16. In a sub-set of studies, risk was elevated with low doses of rofecoxib, 1.37 (1.20, 1.57, celecoxib, 1.26 (1.09, 1.47, and diclofenac, 1.22 (1.12, 1.33, and rose in each case with higher doses. Ibuprofen risk was seen only with higher doses. Naproxen was risk-neutral at all doses. Of the less studied drugs etoricoxib, 2.05 (1.45, 2.88, etodolac, 1.55 (1.28, 1.87, and indomethacin, 1.30 (1.19, 1.41, had the highest risks. In pair-wise comparisons, etoricoxib had a higher RR than ibuprofen, RRR = 1.68 (99% CI 1.14, 2.49, and naproxen, RRR = 1.75 (1.16, 2.64; etodolac was not significantly different from naproxen and ibuprofen.

    2010-01-01

    We investigated the effects of non-steroidal anti-inflammatory drugs on substrate-induced currents of L-glutamate (L-Glu) transporter EAAT1 expressed in Xenopus laevis oocytes. Niflumic acid (NFA) and diclofenac inhibited L-Glu-induced current through EAAT1 in a non-competitive manner. NFA produced a leftward shift in reversal potential (E(rev)) of L-Glu-induced current and increased current amplitude at the potentials more negative than -100 mV. Diclofenac had no effects on E(rev) and inhibited the current amplitude to the same extent at all negative potentials. These results indicate that NFA and diclofenac inhibit the L-Glu-induced EAAT1 current via different mechanisms.

    A sensitive biotin-streptavidin-amplified enzyme-linked immunosorbent assay (BA-ELISA) method was developed for detecting non-steroidal anti-inflammatory drug ketoprofen. Compared with traditional ELISA method, the sensitivity of proposed immunoassay was enhanced by the biotin-streptavidin system. Under the optimal condition, the median inhibitory concentration (IC50) was 0.25 ng mL(-1), with minor cross-reactivity to a number of structural analogs. This developed assay was successfully applied to detect the ketoprofen residues in different fish samples, and good recoveries (72.6-105.5%) were obtained. The results indicated that this immunoassay method could specifically detect trace ketoprofen residues and could be widely used for routine monitoring of food samples.

    We investigated the effect of non-steroidal anti-inflammatory drugs on prostaglandins (PGs) and 12-hydroxyeicosatetraenoic acid (12-HETE) formation by inflamed human gingival tissues. Gingival tissue homogenates were incubated with /sup 14/C-arachidonic acid in the presence of indomethacin, piroxicam, or ibuprofen, and the organic solvent extracts were chromatographed on silica gel plates with standards for radiometric assay. There was a significant negative trend between the doses (10(-7)-10(-3) M) of each of indomethacin, piroxicam, and ibuprofen, and the amounts of PGF2 alpha, PGE2, PGD2, and 15-keto-PGE2 produced. All three drugs have a significant inhibitory effect on PGs and 12-HETE production at 10(-3) M when compared with the control. The rank order effectiveness of the drugs, at 10(-3) M, on PG inhibition was indomethacin greater than piroxicam greater than ibuprofen, and on 12-HETE inhibition was indomethacin greater than ibuprofen greater than piroxicam.

  11. INTERACTION BETWEEN ANTI-HYPERTENSIVE AND NON-STEROIDAL ANTI INFLAMMATORY DRUGS: IMPLICATIONS IN MANAGEMENT OF OSTEOARTHRITIS AND OPINION ON A COMPROMISE THERAPY

    Directory of Open Access Journals (Sweden)

    Mr. Adeolu O. Ajala

    Full Text Available The premise for this article is that a significant proportion of patients presenting in the clinic with osteoarthritis have hypertension as co-morbidity. A common drug of choice in managing symptoms of osteoarthritis including those affecting the knee joint is the Non-Steroidal Anti-Inflammatory Drugs (NSAIDS groups. It has been reported however that NSAIDs diminish the effects of anti-hypertensive drugs and may lead to an ineffective hypertension therapy. In order to avoid complications in the health of the patient with concomitant hypertension and osteoarthritis and who are on both antihypertensive and NSAIDs, it becomes imperative to consider using non-pharmacologic approaches such as physiotherapy in managing the symptoms of osteoarthritis in this group of patients and thereby maximizing the effects of their antihypertensive therapy. This is more so that information exists on efficacy of physiotherapy in form of therapeutic exercises and electrotherapeutic modalities in management of clinical features of osteoarthritis.

    In view of high availability and diversity of non-steroidal anti-inflammatory drugs (NSAIDs) on Polish market it is important for orthodontists to be aware of NSAID effect on the range of orthodontic tooth movement as well as the risk of root resorption in the moved teeth and other adverse effects, which might occur within oral cavity. The disadvantages of NSAID non-selective inhibition of COX include common oral inflammatory conditions, gingival bleeding, and disturbances of salivary secretion. Both, the selective and non-selective COX inhibitors, meloxicam excluded, used to alleviate the pain of orthodontic tooth movement, impede the movement of teeth. Paracetamol, explicitly indicated by most authors as the safest NSAID, seems to be the drug of choice in view of no influence on the range of tooth movement, the risk of root resorption or other adverse effects within oral cavity.

    In recent years measurable concentrations of non-steroidal anti-inflammatory drugs (NSAIDs) have been shown in the aquatic environment as a result of increasing human consumption. Effects of five frequently used non-steroidal anti-inflammatory drugs (diclofenac, diflunisal, ibuprofen, mefenamic acid and piroxicam in 0.1 mg ml(-1) concentration) in batch cultures of cyanobacteria (Synechococcus elongatus, Microcystis aeruginosa, Cylindrospermopsis raciborskii), and eukaryotic algae (Desmodesmus communis, Haematococcus pluvialis, Cryptomonas ovata) were studied. Furthermore, the effects of the same concentrations of NSAIDs were investigated in natural algal assemblages in microcosms. According to the changes of chlorophyll-a content, unicellular cyanobacteria seemed to be more tolerant to NSAIDs than eukaryotic algae in laboratory experiments. Growth of eukaryotic algae was reduced by all drugs, the cryptomonad C. ovata was the most sensitive to NSAIDs, while the flagellated green alga H. pluvialis was more sensitive than the non-motile green alga D. communis. NSAID treatments had weaker impact in the natural assemblages dominated by cyanobacteria than in the ones dominated by eukaryotic algae, confirming the results of laboratory experiments. Diversity and number of functional groups did not change notably in cyanobacteria dominated assemblages, while they decreased significantly in eukaryotic algae dominated ones compared to controls. The results highlight that cyanobacteria (especially unicellular ones) are less sensitive to the studied, mostly hardly degradable NSAIDs, which suggest that their accumulation in water bodies may contribute to the expansion of cyanobacterial mass productions in appropriate environmental circumstances by pushing back eukaryotic algae. Thus, these contaminants require special attention during wastewater treatment and monitoring of surface waters.

    Full Text Available Abstract Background Non-steroidal anti-inflammatory (NSAID medications are a common cause of reported adverse drug side-effects. This study describes the prevalence of non-steroidal anti-inflammatory (NSAID use (other than low-dose aspirin and the presence of co-existing relative contraindications to NSAID use and chronic conditions in a representative population sample. Methods Data were analysed from 3,206 adults attending first follow-up of the North West Adelaide Health Study (NWAHS in 2004 - 2006, a longitudinal representative population study. Medications were brought into study clinic visits by participants. Clinical assessment included measured blood pressure, kidney function, serum cholesterol, blood glucose. Questionnaires assessed demographics, lifestyle risk factors, physician-diagnosed chronic conditions. Data were weighted to census measures by region, age group, gender, and probability of selection in the household, to provide population representative estimates. Pearson's Chi-square tests determined significant differences in proportions. Multiple logistic regression was used to examine associations of socio-demographic characteristics with use of NSAIDs. Results Of 3,175 participants, 357 (11.2%, and 16% of those aged > 55 years, reported using either non-specific NSAIDs or COX-2 inhibitors, other than low-dose aspirin. Among people using NSAIDs, 60.8% had hypertension, 30.8% had Stage 3 or higher chronic kidney disease, 17.2% had a history of cardiovascular disease (CVD and 20.7% had a > 15% 10-year CVD risk.

    1. Nabumetone is a clinically used non-steroidal anti-inflammatory drug, its biotransformation includes major active metabolite 6-methoxy-2-naphtylacetic acid and another three phase I as well as corresponding phase II metabolites which are regarded as inactive. One important biotransformation pathway is carbonyl reduction, which leads to the phase I metabolite, reduced nabumetone. 2. The aim of this study is the determination of the role of a particular human liver subcellular fraction in the nabumetone reduction and the identification of participating carbonyl reducing enzymes along with their stereospecificities. 3. Both subcellular fractions take part in the carbonyl reduction of nabumetone and the reduction is at least in vitro the main biotransformation pathway. The activities of eight cytosolic carbonyl reducing enzymes--CBR1, CBR3, AKR1B1, AKR1B10, AKR1C1-4--toward nabumetone were tested. Except for CBR3, all tested reductases transform nabumetone to its reduced metabolite. AKR1C4 and AKR1C3 have the highest intrinsic clearances. 4. The stereospecificity of the majority of the tested enzymes is shifted to the production of an (+)-enantiomer of reduced nabumetone; only AKR1C1 and AKR1C4 produce predominantly an (-)-enantiomer. This project provides for the first time evidence that seven specific carbonyl reducing enzymes participate in nabumetone metabolism.

    Pharmaceuticals represent a major environmental concern since the knowledge on their occurrence, distribution and ecotoxicological potential is still limited particularly in coastal areas. In this study, bioaccumulation and cellular effects of various non steroidal anti-inflammatory drugs (NSAIDs) were investigated in mussels Mytilus galloprovincialis to reveal whether common molecules belonging to the same therapeutic class might cause different effects on non target organisms. Organisms exposed to environmental concentrations of acetaminophen (AMP), diclofenac (DIC), ibuprofen (IBU), ketoprofen (KET) and nimesulide (NIM) revealed a significant accumulation of DIC, IBU and NIM, while AMP and KET were always below detection limit. Nonetheless, for all tested NSAIDs, measurement of a large panel of ecotoxicological biomarkers highlighted impairment of immunological parameters, onset of genotoxicity and modulation of lipid metabolism, oxidative and neurotoxic effects. Laboratory results were integrated with a field study which provided the first evidence on the occurrence of DIC, IBU and NIM in tissues of wild mussels sampled during summer months from an unpolluted, touristic area of Central Adriatic Sea. Overall results demonstrated M. galloprovincialis as a good sentinel species for monitoring presence and ecotoxicological hazard of pharmaceuticals in the Mediterranean.

    Full Text Available Hepatoprotective effect of plant drugs against hepatic tissue injury induced by non-steroidal anti-inflammatory drugs (NSAIDs was assessed on Beagle dogs. The adverse effects of carprofen and robenacoxib on the hepatic tissue were evaluated on the basis of histopathological examination of liver sections. It was demonstrated that the use of NSAIDs with liquorice and composed plant remedy Pectosol¯ caused a reduction of hepatic adverse effects induced by the administration of NSAIDs. This fact indicates a hepatoprotective effect of the tested plant remedies during the treatment with NSAIDs. However, the results require further studies on a larger group of animals. Liquorice and Pectosol¯ reduce the hepatic side effects, which develop after the treatment with carprofen and, to a lesser extent, robenacoxib in young Beagles. Such studies allow to investigate the negative and positive effects of using robenacoxib and carprofen in dogs and, therefore, help to limit the NSAID-induced side effects on the liver in these animals.

    Alzheimer disease is the most severe neurodegenerative disease worldwide. In the past years, a plethora of small molecules interfering with amyloid-β (Aβ) aggregation has been reported. However, their mode of interaction with amyloid fibers is not understood. Non-steroidal anti-inflammatory drugs (NSAIDs) are known γ-secretase modulators; they influence Aβ populations. It has been suggested that NSAIDs are pleiotrophic and can interact with more than one pathomechanism. Here we present a magic angle spinning solid-state NMR study demonstrating that the NSAID sulindac sulfide interacts specifically with Alzheimer disease Aβ fibrils. We find that sulindac sulfide does not induce drastic architectural changes in the fibrillar structure but intercalates between the two β-strands of the amyloid fibril and binds to hydrophobic cavities, which are found consistently in all analyzed structures. The characteristic Asp(23)-Lys(28) salt bridge is not affected upon interacting with sulindac sulfide. The primary binding site is located in the vicinity of residue Gly(33), a residue involved in Met(35) oxidation. The results presented here will assist the search for pharmacologically active molecules that can potentially be employed as lead structures to guide the design of small molecules for the treatment of Alzheimer disease.

METHODOLOGY: 100 prescription duplicate collected and analyzed prospectively for the pattern of NSAID prescription for arthritic and non - arthritic conditions; the drug formulation , route , frequency, duration of adm issio n and concomitant medications results. NSAID were prescribed for non - traumatic musculo skeletal 35% pain, 25% post traumatic pain, 20% osteoarthritis, 10% post - operative pain, 3% ankylosing spondylitis, 6% degenerativ e disease of spine, 1% neuralgia. The NSAIDs commonly prescribed were Aceclofenac 45%, Etodolac 20%, Diclofenac 24%, and Ibuprofen 11%. Fixed dose combination of NSAIDs with adjuvante was prescribed in. The adjuvants, included are paracetamol 55.6%, serrat opeptidase 32.8%, chlorzoxazone 9.1%, Thiocolchichoside 2.5%. oral formulations of NSAIDs were prescribed in all patients, supplemented by Topical formulations as gel/cream in 15% of subjects. The dosing frequency was BID (65%, OD (25%, TID (2%, SOS (8% . Duration of administration ranged from 5 - 15 days . other classes of drugs used concomitantly were proton pump inhibitors , calcium supplements, Multivitamins, Anti microbials, Immuno suppressants, and Glucosamine. CONCLUSION: NSAIDs were prescribed empiric all y for various arthritic and Non - arthritic conditions, frequently as fixed dose combinations [FDC]s with various adjuvants as per the standard guide lines. However patient information was inadequate in most of the prescriptions. Proper patient Assessment deemed necessary for individualizing NSAIDs.

    Full Text Available BACKGROUND: Despite strong laboratory evidence that non-steroidal anti-inflammatory drugs (NSAIDs could prevent prostate cancer, epidemiological studies have so far reported conflicting results. Most studies were limited by lack of information on dosage and duration of use of the different classes of NSAIDs. METHODS: We conducted a nested case-control study using data from Saskatchewan Prescription Drug Plan (SPDP and Cancer Registry to examine the effects of dose and duration of use of five classes of NSAIDs on prostate cancer risk. Cases (N = 9,007 were men aged ≥40 years diagnosed with prostatic carcinoma between 1985 and 2000, and were matched to four controls on age and duration of SPDP membership. Detailed histories of exposure to prescription NSAIDs and other drugs were obtained from the SPDP. RESULTS: Any use of propionates (e.g., ibuprofen, naproxen was associated with a modest reduction in prostate cancer risk (Odds ratio = 0.90; 95%CI 0.84-0.95, whereas use of other NSAIDs was not. In particular, we did not observe the hypothesized inverse association with aspirin use (1.01; 0.95-1.07. There was no clear evidence of dose-response or duration-response relationships for any of the examined NSAID classes. CONCLUSIONS: Our findings suggest modest benefits of at least some NSAIDs in reducing prostate cancer risk.

    Non-steroidal anti-inflammatory drug, Diclofenac, targeting COX have shown promise in the treatment of Acanthamoeba keratitis, but the underlying mechanisms remain unknown. Using various NSAIDs, Diclofenac sodium, Indomethacin, and Acetaminophen, here we determined the effects of NSAIDs on the biological properties of Acanthamoeba castellanii belonging to the T4 genotype. Using amoebicidal assays, the results revealed that Diclofenac sodium, and Indomethacin affected growth of A. castellanii. In contrast, none of the compounds tested had any effect on the viability of A. castellanii. Importantly, all NSAIDs tested abolished A. castellanii encystation. This is a significant finding as the ability of amoebae to transform into the dormant cyst form presents a significant challenge in the successful treatment of infection. The NSAIDs inhibit production of cyclo-oxegenase, which regulates the synthesis of prostaglandins suggesting that cyclooxygenases (COX-1 and COX-2) and prostaglandins play significant role(s) in Acanthamoeba biology. As NSAIDs are routinely used in the clinical practice, these findings may help design improved preventative strategies and/or of therapeutic value to improve prognosis, when used in combination with other anti-amoebic drugs.

    As part of a commercial embryo transfer programme, 20 embryos were transferred to spontaneously synchronous or synchronized recipient mares. In 14 cases, embryo recipients were treated with non-steroidal anti-inflammatory drugs (NSAID), receiving flunixin meglumine i.v. at the time of transfer and vedaprofen orally twice a day on the 3 days after embryo transfer, while six embryos were transferred to untreated mares that served as controls. Out of the 14 recipient mares treated with NSAID, 11 (79%) were pregnant at 6-8 days after transfer and in 10 mares, the pregnancy was continued. From the six untreated recipients, only one became pregnant but underwent early embryonic death between day 14 and 35 after ovulation. In conclusion, pregnancy rate in NSAID-treated recipients is higher than that in untreated recipients and above reported average values, indicating that treatment of recipient mares with NSAID helps to increase pregnancy rates after transcervical transfer and can be recommended for equine embryo transfer.

    Graphene aerogel (GA)-supported metal-organic framework (MOF) particles with a three-dimensional (3D) architecture were fabricated for the first time via a facile template-free "sol-cryo" method. The prepared MOFs@graphene hybrid aerogels exhibit a 3D interconnected macroporous framework of graphene sheets with uniform dispersion of MOF particles. We also report the first attempt at using the hybrid aerogels as adsorbents for the solid-phase extraction (SPE) of non-steroidal anti-inflammatory drugs (NSAIDs) and the selective enrichment of proteins. The macroporous skeletons of GA provide both low backpressure and rapid mass transfer in SPE application, thus overcoming the obstacle of high backpressure caused by directly packing submicron or micron sized MOF particles into SPE cartridges. Excellent performances including satisfactory recoveries, high sensitivity and good reproducibility were achieved in the extraction of five NSAIDs. The hybrid aerogels also showed an interesting ability for selective enrichment of ribonuclease A (RNase A) and simultaneous exclusion of cytochrome C (Cyt C) and lysozyme (Lyz), which could be attributed to the electrostatic interactions between proteins and the positively charged coordinatively unsaturated metal sites (CUS) in MIL-101. We believe that this work will promote the application of MOFs in adsorption and separation, and our synthetic strategy could be further extended to develop other graphene-based hybrid aerogels.

    A reliable and simple method for the detection and quantification of residues of 14 non-steroidal anti-inflammatory drugs and a metamizole metabolite in swine muscle was developed using liquid chromatography-electrospray ionisation-tandem mass spectrometry (LC-ESI-MS/MS). The samples were extracted with acetonitrile (ACN) in solid-liquid extraction followed by a low-temperature partitioning (LLE-LTP) process at -20 ± 2°C. After evaporation to dryness, the residue was reconstituted with hexane and a mixture of water:acetonitrile (1:1). LC separation was achieved on a reversed-phase (RP18) column with gradient elution using water (phase A) and ACN (phase B) both containing 1 mmol l(-)(1) ammonium acetate (NH4COO) with 0.025% acetic acid. Analysis was carried out on a triple-quadrupole tandem mass spectrometer (LC-MS/MS) in multiple reaction monitoring mode using an electrospray interface in negative and positive mode in a single run. Method validation was performed according to the criteria of Commission Decision No. 2002/657/EC. The matrix effect and linearity were evaluated. Decision limit (CCα), detection capability (CCβ), accuracy and repeatability of the method are also reported. The proposed method proved to be simple, easy and adequate for high-throughput analysis and was applied to routine analysis by the Brazilian Ministry of Agriculture, Livestock and Food Supply.

    The interaction of Cd(II) with the non-steroidal anti-inflammatory drug diclofenac sodium (Dic) leads to the formation of the complex [Cd2(L)41.5(MeOH)2(H2O)]n(L = Dic), 1, which has been isolated and structurally characterized by X-ray crystallography. Diclofenac sodium and its metal complex 1 have also been evaluated for antiproliferative activity in vitro against the cells of three human cancer cell lines, MCF-7 (breast cancer cell line), T24 (bladder cancer cell line), A-549 (non-small cell lung carcinoma), and a mouse fibroblast L-929 cell line. The results of cytotoxic activity in vitro expressed as IC50 values indicated the diclofenac sodium and cadmium chloride are non active or less active than the metal complex of diclofenac (1). Complex 1 was also found to be a more potent cytotoxic agent against T-24 and MCF-7 cancer cell lines than the prevalent benchmark metallodrug, cisplatin, under the same experimental conditions. The superoxide dismutase activity was measured by Fridovich test which showed that complex 1 shows a low value in comparison with Cu complexes. The binding properties of this complex to biomolecules, bovine or human serum albumin, are presented and evaluated. Antibacterial and growth inhibitory activity is also higher than that of the parent ligand compound.

  19. Non-steroidal anti-inflammatory drugs decrease E2F1 expression and inhibit cell growth in ovarian cancer cells.

    Full Text Available Epidemiological studies have shown that the regular use of non-steroidal anti-inflammatory (NSAIDs drugs is associated with a reduced risk of various cancers. In addition, in vitro and experiments in mouse models have demonstrated that NSAIDs decrease tumor initiation and/or progression of several cancers. However, there are limited preclinical studies investigating the effects of NSAIDs in ovarian cancer. Here, we have studied the effects of two NSAIDs, diclofenac and indomethacin, in ovarian cancer cell lines and in a xenograft mouse model. Diclofenac and indomethacin treatment decreased cell growth by inducing cell cycle arrest and apoptosis. In addition, diclofenac and indomethacin reduced tumor volume in a xenograft model of ovarian cancer. To identify possible molecular pathways mediating the effects of NSAID treatment in ovarian cancer, we performed microarray analysis of ovarian cancer cells treated with indomethacin or diclofenac. Interestingly, several of the genes found downregulated following diclofenac or indomethacin treatment are transcriptional target genes of E2F1. E2F1 was downregulated at the mRNA and protein level upon treatment with diclofenac and indomethacin, and overexpression of E2F1 rescued cells from the growth inhibitory effects of diclofenac and indomethacin. In conclusion, NSAIDs diclofenac and indomethacin exert an anti-proliferative effect in ovarian cancer in vitro and in vivo and the effects of NSAIDs may be mediated, in part, by downregulation of E2F1.

    Gastrotoxic activities of different non-steroidal anti-inflammatory drugs (NSAIDs) (diclofenac, indomethacin, ketoprofen, naproxen and piroxicam) administered per os were compared with their ability to inhibit gastric prostaglandin E2 (PGE2) synthesis in the rat. In a parallel study, effects of pretreatment with zinc acexamate (ZAC) were also assessed. NSAIDs invariably caused gastric mucosal damage and a decrease of PGE2 levels. A good correlation between the decrease of PGE2 levels and the index of gastric lesion (r = 0.41; p < 0.021) was observed when results obtained with the different NSAIDs were pooled. ZAC pretreatment significantly decreased the overall severity of lesions induced by NSAIDs. However, no correlation between gastric lesion index and depletion of PGE2 gastric levels was observed after treatment with ZAC (r = 0.012; p < 0.948). These data corroborate the hypothesis that preservation of the capability to synthesize endogenous PGs is of critical importance in the maintenance of gastric mucosal integrity. The gastroprotective action observed with ZAC involves alternative mechanisms other than modification of PGE2 levels.

    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.

    AIM: To evaluate the gastric permeability after both acute and chronic use of non-steroidal anti-inflammatory drugs (NSAIDs) and to assess the clinical usefulness of sucrose test in detecting and following NSAIDs- induced gastric damage mainly in asymptomatic patients and the efficacy of a single pantoprazole dose in chronic users.METHODS: Seventy-one consecutive patients on chronic therapy with NSAIDs were enrolled in the study and divided into groups A and B (group A receiving 40 mg pantoprazole daily, group B only receiving NSAIDs). Sucrose test was performed at baseline and after 2, 4 and 12 wk,respectively. The symptoms in the upper gastrointestinal tract were recorded.RESULTS: The patients treated with pantoprazole had sucrose excretion under the limit during the entire follow-up period. The patients without gastroprotection had sucrose excretion above the limit after 2 wk, with an increasing trend in the following weeks (P = 0.000). A number of patients in this group revealed a significantly altered gastric permeability although they were asymptomatic during the follow-up period.CONCLUSION: Sucrose test can be proposed as a valid tool for the clinical evaluation of NSAIDs- induced gastric damage in both acute and chronic therapy. This tecnique helps to identify patients with clinically silent gastric damages. Pantoprazole (40 mg daily) is effective and well tolerated in chronic NSAID users.

    Full Text Available Abstract Background Chronic pancreatitis is characterized by progressive fibrosis, pain and loss of exocrine and endocrine functions. The long-standing chronic pancreatitis and its associated pancreatic fibrosis are the most common pathogenic events involved in human pancreatic carcinogenesis, but the therapeutic strategies to chronic pancreatitis and the chemoprevention of pancreatic carcinogenesis are very limited. Methods We investigated the effect of sulindac, a non-steroidal anti-inflammatory drug (NSAID, on inhibition of chronic pancreatitis in a caerulein induced chronic pancreatitis mouse model. Results Sulindac significantly reduced the severity of chronic pancreatitis including the extent of acini loss, inflammatory cell infiltration and stromal fibrosis. The protein expression of phosphorylation of MEK/ERK was inhibited in the chronic pancreatic tissues by sulindac treatment as measured by Western blot assay. The levels of inflammatory cytokines including TNF-α and MCP-1 were also significantly decreased with sulindac treatment, as well as the expression of TGF-β, PDGF-β, SHH and Gli in the chronic pancreatic tissue detected by qPCR assay and confirmed by western blot assay. The activation of pancreatic satellet cells was also inhibited by sulindac as measured by the activity of α-smooth muscle actin (α-SMA in the pancreatic tissue of chronic pancreatitis. Conclusions Sulindac is a promising reagent for the treatment of chronic pancreatitis via inhibition of inflammatory cell infiltration and stromal fibrosis, the inhibitory effect of sulindac on chronic pancreatitis may through targeting the activation ERK/MAPK signaling pathway.

    Full Text Available Increasing drug resistance has brought enormous challenges to the management of Trichosporon spp. infections. The in vitro antifungal activities of non-steroidal anti-inflammatory drugs (NSAIDs against Candida spp. and Cryptococcus spp. were recently discovered. In the present study, the in vitro interactions between three NSAIDs (aspirin, ibuprofen and diclofenac sodium and commonly used antifungal agents (fluconazole, itraconazole, voriconazole, caspofungin and amphotericin B against planktonic and biofilm cells of T. asahii were evaluated using the checkerboard microdilution method. The spectrophotometric method and the XTT reduction assay were used to generate data on biofilm cells. The fractional inhibitory concentration index (FICI and the ΔE model were compared to interpret drug interactions. Using the FICI, the highest percentages of synergistic effects against planktonic cells (86.67% and biofilm cells (73.33% were found for amphotericin B/ibuprofen, and caspofungin/ibuprofen showed appreciable percentages (73.33% for planktonic form and 60.00% for biofilm as well. We did not observe antagonism. The ΔE model gave consistent results with FICI (86.67%. Our findings suggest that amphotericin B/ibuprofen and caspofungin/ibuprofen combinations have potential effects against T. asahii. Further in vivo and animal studies to investigate associated mechanisms need to be conducted.

    BACKGROUND Although Helicobacter pylori and non-steroidal anti-inflammatory drugs (NSAIDs) are the main causes of peptic ulcers disease (PUD), recently the prevalence of idiopathic peptic ulcer (IPU) is increasing in most parts of the world. The aim of this study was to assess the prevalence of IPU in Kerman, the center of largest province in south-east Iran. METHODS We included 215 patients with peptic ulcer in our study. Combined methods rapid urease test (RUT), histology, and real time polymerase chain reaction (PCR) was performed on endoscopic samples of peptic ulcers. NSAID use was determined by medical history. SPSS software version 16 was used for data analysis. p valueulcer, four (1.8%) had H.pylorinegative and NSAID-negative PUD. There were not significant differences between patients with IPU and patients with peptic ulcer associated with H.pylori or NSAIDs regarding the sex, age, cigarette smoking, and opioid abuse. CONCLUSION Our study showed that in contrast to other reports from western and some Asian countries, the prevalence of IPU is low in Kerman and H.pylori infection is still the major cause of PUD. We recommend a large and multi-central study to determine the prevalence of IPU in Iran.

    Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs are the most consumed drugs worldwide because of their efficacy and utility in the treatment of pain and inflammatory diseases. However, they are also responsible for an important number of adverse effects including hypersensitivity reactions. The most important group of these reactions is triggered by non-immunological, pharmacological mechanisms catalogued under the denomination of cross-intolerance (CRI, with acute urticaria/angioedema induced by multiple NSAIDs (MNSAID-UA the most frequently associated clinical entity. A recent genome-wide association study identified the gene encoding the centrosomal protein of 68 KDa (CEP68 as the major locus associated with aspirin intolerance susceptibility in asthmatics. In this study, we aimed to assess the role of this locus in susceptibility to CRI to NSAIDs by examining 53 common gene variants in a total of 635 patients that were classified as MNSAID-UA (n = 399, airway exacerbations (n = 110 or blended pattern (n = 126, and 425 controls. We found in the MNSAID-UA group a number of variants (17 associated (lowest p-value = 1.13 × 10(-6, including the non-synonymous Gly74Ser variant (rs7572857 previously associated with aspirin intolerance susceptibility in asthmatics. Although not being significant in the context of multiple testing, eight of these variants were also associated with exacerbated respiratory disease or blended reactions. Our results suggest that CEP68 gene variants may play an important role in MNSAID-UA susceptibility and, despite the different regulatory mechanisms involved depending on the specific affected organ, in the development of hypersensitivity reactions to NSAIDs.

    Full Text Available In subjects with non-steroidal anti-inflammatory drugs (NSAIDs- exacerbated respiratory disease (NERD symptoms are triggered by acetyl salicylic acid (ASA and other strong COX-1 inhibitors, and in some cases by weak COX-1 or by selective COX-2 inhibitors. The mechanism involved is related to prostaglandin pathway inhibition and leukotriene release. Subjects who react to a single NSAID and tolerate others are considered selective responders, and often present urticaria and/or angioedema and anaphylaxis (SNIUAA. An immunological mechanism is implicated in these reactions. However, anecdotal evidence suggests that selective responders who present respiratory airway symptoms may also exist.Our objective was to determine if subjects might develop selective responses to NSAIDs/paracetamol that manifest as upper/lower airways respiratory symptoms. For this purpose we studied patients reporting asthma and/or rhinitis induced by paracetamol or a single NSAID that tolerated ASA. An allergological evaluation plus controlled challenge with ASA was carried out. If ASA tolerance was found, we proceeded with an oral challenge with the culprit drug. The appearance of symptoms was monitored by a clinical questionnaire and by measuring FEV1 and/or nasal airways volume changes pre and post challenge. From a total of 21 initial cases, we confirmed the appearance of nasal and/or bronchial manifestations in ten, characterised by a significant decrease in FEV1% and/or a decrease in nasal volume cavity after drug administration. All cases tolerated ASA.This shows that ASA tolerant subjects with asthma and/or rhinitis induced by paracetamol or a single NSAID without skin/systemic manifestations exist. Whether these patients represent a new clinical phenotype to be included within the current classification of hypersensitivity reactions to NSAIDs requires further investigation.

    Full Text Available Abstract Background Cross national drug utilization studies can provide information about different influences on physician prescribing. This is important for medicines with issues around safety and quality of use, like non selective non-steroidal anti-inflammatory drugs (ns-NSAIDs and cyclo-oxygenase-2 (COX-2 inhibitors. To enable comparison of prescription medicine use across different jurisdictions with a range of population sizes, data first need to be compared within Australia to understand whether use in a smaller sub-population may be considered as representative of the total use within Australia. The aim of this study was to compare the utilization of non selective NSAID, COX-2 inhibitors and paracetamol between Queensland and Australia. Method Dispensing data were obtained for concession beneficiaries for Australia for ns-NSAIDs, COX-2 inhibitors and paracetamol subsidized by the PBS over the period 1997–2003. The same data were purchased for Queensland. Data were converted to Defined Daily Dose (DDD/1000 beneficiaries/day (World Health Organization anatomical therapeutic chemical classification, 2005. Results Total NSAID and paracetamol consumption were similar in Australia and Queensland. Ns-NSAID use decreased sharply with the introduction of COX-2 inhibitors (from approximately 80 to 40 DDD/1000 beneficiaries/day. Paracetamol was constant (approximately 45 DDD/1000 beneficiaries/day. COX-2 inhibitors consumption was initially higher in Queensland than in the whole of Australia. Conclusion Despite initial divergence in celecoxib use between Queensland and Australia, the use of ns-NSAIDs, COX-2 inhibitors and paracetamol overall, in concession beneficiaries, was comparable in Australia and Queensland.

    Full Text Available BACKGROUND: Drug-Drug Interactions between Non Steroidal Anti-Inflammatory Drugs (NSAIDs and Angiotensin Converting Enzyme Inhibitors (ACEIs, Angiotensin Receptor Blocker (ARBs or diuretics can lead to renal failure and hyperkalemia. Thus, monitoring of serum creatinine and potassium is recommended when a first dispensing of NSAID occur in patients treated with these drugs. METHODS: We conducted a pharmacoepidemiological retrospective cohort study using data from the French Health Insurance Reimbursement Database to evaluate the proportion of serum creatinine and potassium laboratory monitoring in patients treated with ACEI, ARB or diuretic and receiving a first dispensing of NSAID. We described the first dispensing of NSAID among 3,500 patients of a 4-year cohort (6,633 patients treated with antihypertensive drugs and analyzed serum creatinine and potassium laboratory monitoring within the 3 weeks after the first NSAID dispensing. RESULTS: General Practitioners were the most frequent prescribers of NSAIDs (85.5%, 95% CI: 84.3-86.6. The more commonly prescribed NSAIDs were ibuprofen (20%, ketoprofen (15%, diclofenac (15% and piroxicam (12%. Serum creatinine and potassium monitoring was 10.7% (95% CI: 9.5-11.8 in patients treated by ACEIs, ARBs or diuretics. Overall, monitoring was more frequently performed to women aged over 60, treated with digoxin or glucose lowering drugs, but not to patients treated with ACEIs, ARBs or diuretics. Monitoring was more frequent when NSAIDs' prescribers were cardiologists or anesthesiologists. CONCLUSION: Monitoring of serum creatinine and potassium of patients treated with ACEIs, ARBs or diuretics and receiving a first NSAID dispensing is insufficiently performed and needs to be reinforced through specific interventions.

    The YacK gene from Yersinia enterocolitica strain 7, cloned in pET28a vector and expressed in Escherichia coli BL21 (DE3), showed laccase activity when oxidized with 2,2'-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) and guaiacol. The recombinant laccase protein was purified and characterized biochemically with a molecular mass of ≈58 KDa on SDS-PAGE and showed positive zymogram with ABTS. The protein was highly robust with optimum pH 9.0 and stable at 70 °C upto 12 h with residual activity of 70%. Kinetic constants, Km values, for ABTS and guaiacol were 675 μM and 2070 μM, respectively, with corresponding Vmax values of 0.125 μmol/ml/min and 6500 μmol/ml/min. It also possess antioxidative property against BSA and Cu(2+)/H2O2 model system. Constant pH MD simulation studies at different protonation states of the system showed ABTS to be most stable at acidic pH, whereas, diclofenac at neutral pH. Interestingly, aspirin drifted out of the binding pocket at acidic and neutral pH, but showed stable binding at alkaline pH. The biotransformation of diclofenac and aspirin by laccase also corroborated the in silico results. This is the first report on biotransformation of non-steroidal anti-inflammatory drugs (NSAIDs) using recombinant laccase from gut bacteria, supported by in silico simulation studies.

    Occurrence of five non-steroidal anti-inflammatory drugs (salicylic acid, ibuprofen, naproxen, indomethacin and diclofenac) and three lipid regulators (bezafibrate, clofibric acid and gemfibrozil) was investigated in wastewater, sewage sludge, and river water of the urban section of the Pearl River at Guangzhou in South China. Behavior and fate of the pharmaceuticals during treatment in two sewage treatment plants (STPs) were also studied in depth by determining concentrations in the influents and effluents at major treatment units and the sewage sludge. Concentrations of the pharmaceuticals in the raw wastewater were mostly at ng L(-1) levels except salicylic acid whose concentrations ranged from 9.6 to 23.3 μg L(-1). No significant amount of the pharmaceuticals was detected in the suspended particulate matter of wastewater and sewage sludge. Salicylic acid, indomethacin, and naproxen were almost completely removed (≥ 99%); gemfibrozil, ibuprofen and bezafibrate were significantly removed (>75%), whereas diclofenac and clofibric acid were removed by 60-70% during treatment in the STPs. Generally, biodegradation was the governing process for elimination of the investigated pharmaceuticals. Anaerobic biodegradation was responsible for most of the removal of diclofenac whereas aerobic biodegradation also played an important role in elimination of the other pharmaceuticals except SA, which was nearly completely removed after the anoxic process. In the Pearl River, the pharmaceuticals were widely detected. Both the concentrations and detection frequency were higher in March 2008 than those in the other seasons, which may be ascribed mainly to less dilution caused by lower precipitation. Besides the STPs, urban canals directly connected with the Pearl River may also be important contributors to the pharmaceutical contamination in the river.

    Endocrine disrupting chemicals and non-steroidal anti-inflammatory drugs are two important groups of emerging pollutants due to their toxicological and chemical characteristics and their persistent detection in the aquatic environment. Wastewater treatment plants are a significant pathway for their transfer to the water courses. It is well evidenced that these chemicals are only partially removed through biological treatment of wastewater and therefore being detected in secondary effluents. This work focuses on the evaluation of the efficiency of two well-established disinfection technologies (chlorination and UV irradiation) along with UV/H2O2 and powdered activated carbon (PAC) to remove these chemicals from biologically treated wastewater. Based on the results it is shown that appreciable removal efficiencies due to chlorination should be expected for most of the target compounds, whereas this was not the case for ibuprofen and ketoprofen. With the exemption of diclofenac and ketoprofen direct UV irradiation did not efficiently removed target compounds for UV doses usually applied for disinfection purposes. The application of advanced UV treatment through the addition of H2O2 although resulted in increased removal of the target compounds is not sufficient at moderate UV and H2O2 doses to achieve satisfactory removal efficiencies. PAC use resulted in sufficient removal of target compounds although high PAC doses were required for some chemicals. Comparison of Freundlich isotherms of this study with those of other studies, derived employing water samples, suggested that the water matrix along with the target compounds concentration range can significantly affect the outcome of the experiments.

    Full Text Available Non-steroidal anti-inflammatory agents (NSAIDs are known to be associated with renal damage. No clear evidence exists regarding differential risk of chronic kidney disease (CKD, specifically, across various NSAIDs.The aim of this population-based case-control study was to evaluate the association between use of individual NSAIDs and risk of CKD in a general population of Southern Italy.A nested case-control study was carried out using the general practice Arianna database, identifying incident CKD patients as cases and matched controls from 2006 to 2011. The date of first CKD diagnosis was defined as the index date (ID. Conditional logistic regressions were performed to estimate the risk of CKD associated with NSAIDs by class and individual drugs as compared to non-use during different time windows (within one year, six or three months prior to ID, with the latter being defined as current users. Among current users, the effect of cumulative exposure to these drugs was evaluated.Overall, 1,989 CKD cases and 7,906 matched controls were identified. A statistically significant increase in the risk of CKD was found for current users of oxicams (adjusted OR: 1.68; 95% CI: 1.15-2.44 and concerning individual compounds, for ketorolac (adj. OR: 2.54; 95% CI: 1.45-4.44, meloxicam (adj. OR: 1.98; 95% CI: 1.01-3.87 and piroxicam (adj. OR: 1.95; 95% CI: 1.19-3.21.The risk of CKD varies across individual NSAIDs. Increased risk has been found for ketorolac, which may precipitate subclinical CKD through acute renal damage, and long-term exposure to oxicams, especially meloxicam and piroxicam.

    Over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol are most commonly the first-line pharmacotherapy in combating different pain and inflammatory disorders and fever. Unfortunately, those drugs might have serious side effects, especially when they are used in an inappropriate way. The aim of the study was to explore various aspects of NSAIDs and paracetamol use in the self-therapy of miscellaneous disorders in young adults. The questionnaire-based survey comprised 250 consecutive students aged 22.1 ± 1.9 years (189 women) of diverse fields of study. The drugs were applied in clinical conditions in which they should be avoided including asthma attack (1.2%), vomiting (2.4%), malaise and depression (3.6%), in autumn and winter as a preventive measure against infections (14.0%), heart-burn (2.0%) and during food poisoning (16.0%). As many as 6.0% of the students claimed that studied medications are ultimately free of adverse reactions. Men more frequently than women used NSAIDs and paracetamol during alcohol consumption (49.2% vs 30.7%, p = 0.009, respectively) but less often were aware that there are maximum doses of medications which should not be exceeded (57.4% vs 76.7%, p = 0.003, respectively). The students of medical-related degree courses (n = 82) compared with individuals of other subjects (n = 168) declared they more often have the custom of always reading medications' leaflets (46.3% vs 31.0%, p = 0.017, respectively). Side effects of medicines were reported by 65 participants - 26.0%. In conclusion, students' knowledge about NSAIDs and paracetamol is low. Participants do not search for information on drug related endangerments, the medication group choice for the given disorder is often inappropriate and the drugs are applied in conditions in which they are contraindicated.

    Full Text Available Pain is not only an unpleasant sensation but also increases morbidity of any operation like atelectasis, ileus, requirement of intensive care and increase in hospital stay. By neuro-modulation based on the gate control theory, we can achieve the similar results as with pharmaceutics without their side effects. Aim of this study was to compare the Non-Steroidal Anti-Inflammatory Drug (NSAID with Transcutaneous Nerve Stimulation (TENS in terms of postoperative pain and duration of pain relief by using a visual analogue scale. MATERIAL AND METHODS Our study included open cholecystectomy patients, 25 patients in each group (Groups I with NSAID, group II with TENS use. The lower limit of age was 20 years. All patients who underwent open cholecystectomy and above 20 years of age without any comorbidities were included in the study. Data was analysed by using SPSS software version 16. RESULTS In TENS therapy group, patient’s acceptance was 84%. Patients in group I had a higher VAS score and less duration of pain relief than group II at 24 and 48 hours (VAS = 4 v/s 2, duration of pain relief = 8.0 and 8.8 hours v/s 10.8 and 11.2 hours. Average numbers of application for the group I was higher than group II (3 v/s 2.1. Both showed no complications of pain equal physiologic parameters like pulse and blood pressure, so both modalities were effective in controlling pain. CONCLUSION TENS can be used without analgesic for the postoperative pain of cholecystectomy with good patient acceptance and effectiveness.

    Polymer monolith microextraction (PMME) based on capillary monolithic column is an effective and useful technique to preconcentrate trace analytes from environmental and biological samples. Here, we report the fabrication of a novel aluminum terephthalate metal-organic framework (MIL-53(Al)) incorporated capillary monolithic column via in situ polymerization for the PMME of non-steroidal anti-inflammatory drugs (NSAIDs) (ketoprofen, fenbufen and ibuprofen) in water and urine samples. The fabricated MIL-53(Al) incorporated monolith was characterized by X-ray powder diffractometry, scanning electron microscopy, Fourier transform infrared spectrometry, and nitrogen adsorption experiment. The MIL-53(Al) incorporated monolith gave larger surface area than the neat polymer monolith. A 2-cm long MIL-53(Al) incorporated capillary monolith was applied for PMME coupled with high-performance liquid chromatography for the determination of the NSAIDs. Potential factors affecting the PMME were studied in detail. Under the optimized conditions, the developed method gave the enhancement factors of 46-51, the linear range of 0.40-200μgL(-1), the detection limits (S/N=3) of 0.12-0.24μgL(-1), and the quantification limits (S/N=10) of 0.40-0.85μgL(-1). The recoveries for spiked NSAIDs (20μgL(-1)) in water and urine samples were in the range of 77.3-104%. Besides, the MIL-53(Al) incorporated monolith was stable enough for 120 extraction cycles without significant loss of extraction efficiency. The developed method was successfully applied to the determination of NSAIDs in water and urine samples.

However, they are also responsible for an important number of adverse effects including hypersensitivity reactions. The most important group of these reactions is triggered by non-immunological, pharmacological mechanisms catalogued under the denomination of cross-intolerance (CRI), with acute urticaria/angioedema induced by multiple NSAIDs (MNSAID-UA) the most frequently associated clinical entity. A recent genome-wide association study identified the gene encoding the centrosomal protein of 68 KDa (CEP68) as the major locus associated with aspirin intolerance susceptibility in asthmatics. In this study, we aimed to assess the role of this locus in susceptibility to CRI to NSAIDs by examining 53 common gene variants in a total of 635 patients that were classified as MNSAID-UA (n = 399), airway exacerbations (n = 110) or blended pattern (n = 126), and 425 controls. We found in the MNSAID-UA group a number of variants (17) associated (lowest p-value = 1.13×10−6), including the non-synonymous Gly74Ser variant (rs7572857) previously associated with aspirin intolerance susceptibility in asthmatics. Although not being significant in the context of multiple testing, eight of these variants were also associated with exacerbated respiratory disease or blended reactions. Our results suggest that CEP68 gene variants may play an important role in MNSAID-UA susceptibility and, despite the different regulatory mechanisms involved depending on the specific affected organ, in the development of hypersensitivity reactions to NSAIDs.

    Full Text Available BACKGROUND: Chronic inflammation has been linked to cancers, and use of non-steroidal anti-inflammatory drugs (NSAIDs has been associated with reduced risk of several cancers. To further refine the magnitude of NSAID-related associations, in particular for cancers related to inflammation, such as alcohol-, infection-, obesity-, and smoking-related cancers, as well as for less common cancers, we evaluated the use of NSAIDs and cancer risk in a very large cohort. We used propensity scores to account for potential selection bias and hypothesized that NSAID use is associated with decreased cancer incidence. METHODS: We conducted a prospective study among 314,522 participants in the NIH-AARP Diet and Health Study. Individuals who completed the lifestyle questionnaire, which included NSAID use, in 1996-1997 were followed through 2006. Information on cancer incidence was ascertained by linking to cancer registries and vital status databases. FINDINGS: During 2,715,994 person-years of follow-up (median 10.1 person-years, there were 51,894 incident cancers. Compared with non-users of NSAIDs, individuals who reported use in the 12 months prior to interview had a significantly lower risk of all inflammation-related cancer, alcohol-related, infection-related, obesity-related, and smoking-related cancers [hazard ratio (HR (95% CI 0.90 (0.87-0.93, 0.80 (0.74-0.85, 0.82 (0.78-0.87, 0.88 (0.84-0.92, and 0.88 (0.85-0.92 respectively]. CONCLUSIONS: After accounting for potential selection bias, our data showed an inverse association between NSAID use and alcohol-related, infection-related, obesity-related, and smoking-related cancers and support the hypothesis that inflammation is related to an increased risk of certain cancers.

    AIM To critically appraise the published randomized,controlled trials on the prophylactic effectiveness ofthe non-steroidal anti-inflammatory drugs (NSAIDs),in reducing the risk of post-endoscopic retrogradecholangiopancreatography (ERCP) pancreatitis.METHODS: A systematic literature search (MEDLINE,Embase and the Cochrane Library, from inception of thedatabases until May 2015) was conducted to identifyrandomized, clinical trials investigating the role ofNSAIDs in reducing the risk of post-ERCP pancreatitis.Random effects model of the meta-analysis was carriedout, and results were presented as odds ratios (OR)with corresponding 95%CI.RESULTS: Thirteen randomized controlled trials on3378 patients were included in the final meta-analysis.There were 1718 patients in the NSAIDs group and 1660patients in non-NSAIDs group undergoing ERCP. Theuse of NSAIDs (through rectal route or intramuscularroute) was associated with the reduced risk of post-ERCPpancreatitis [OR, 0.52 (0.38-0.72), P = 0.0001]. Theuse of pre-procedure NSAIDs was effective in reducingapproximately 48% incidence of post-ERCP pancreatitis,number needed to treat were 16 with absolute riskreduction of 0.05. But the risk of post-ERCP pancreattiswas reduced by 55% if NSAIDs were administered afterprocedure. Similarly, diclofenac was more effective (55%)prophylactic agent compared to indomethacin (41%).CONCLUSION: NSAIDs seem to have clinically provenadvantage of reducing the risk of post-ERCP pancreatitis.

    Full Text Available Abstract Background Recent data indicate that chronic use of coxibs leads to an increased occurrence of thrombotic cardiovascular events. This raises the question as to whether traditional non-steroidal anti-inflammatory drugs (tNSAIDs might also produce similar hazards. Our aim has been to evaluate the association between the chronic use of tNSAIDs and the risk of myocardial infarction (MI in patients. Methods We performed a nested case-control analysis with 4,975 cases of acute MI and 20,000 controls, frequency matched to cases by age, sex, and calendar year. Results Overall, current use of tNSAID was not associated with an increased risk of MI (RR:1.07;95%CI: 0.95–1.21. However, we found that the relative risk (RR of MI for durations of tNSAID treatment of >1 year was 1.21 (95% CI, 1.00–1.48. The corresponding RR was 1.34 (95% CI, 1.06–1.70 for non-fatal MI. The effect was independent from dose. The small risk associated with long-term use of tNSAIDs was observed among patients not taking low-dose aspirin (RR: 1.29; 95% CI, 1.01–1.65. The effect of long-term use for individual tNSAIDs ranged from a RR of 0.87 (95% CI, 0.47–1.62 with naproxen to 1.38 (95% CI, 1.00–1.90 with diclofenac. Conclusion This study adds support to the hypothesis that chronic treatment with some tNSAIDs is associated with a small increased risk of non-fatal MI. Our data are consistent with a substantial variability in cardiovascular risks between individual tNSAIDs.

    Full Text Available The release of reactive oxygen specie (ROS by activated neutrophil is involved in both the antimicrobial and deleterious effects in chronic inflammation. The objective of the present investigation was to determine the effect of therapeutic plasma concentrations of non-steroidal anti-inflammatory drugs (NSAIDs on the production of ROS by stimulated rat neutrophils. Diclofenac (3.6 µM, indomethacin (12 µM, naproxen (160 µM, piroxicam (13 µM, and tenoxicam (30 µM were incubated at 37ºC in PBS (10 mM, pH 7.4, for 30 min with rat neutrophils (1 x 10(6 cells/ml stimulated by phorbol-12-myristate-13-acetate (100 nM. The ROS production was measured by luminol and lucigenin-dependent chemiluminescence. Except for naproxen, NSAIDs reduced ROS production: 58 ± 2% diclofenac, 90 ± 2% indomethacin, 33 ± 3% piroxicam, and 45 ± 6% tenoxicam (N = 6. For the lucigenin assay, naproxen, piroxicam and tenoxicam were ineffective. For indomethacin the inhibition was 52 ± 5% and diclofenac showed amplification in the light emission of 181 ± 60% (N = 6. Using the myeloperoxidase (MPO/H2O2/luminol system, the effects of NSAIDs on MPO activity were also screened. We found that NSAIDs inhibited both the peroxidation and chlorinating activity of MPO as follows: diclofenac (36 ± 10, 45 ± 3%, indomethacin (97 ± 2, 100 ± 1%, naproxen (56 ± 8, 76 ± 3%, piroxicam (77 ± 5, 99 ± 1%, and tenoxicam (90 ± 2, 100 ± 1%, respectively (N = 3. These results show that therapeutic levels of NSAIDs are able to suppress the oxygen-dependent antimicrobial or oxidative functions of neutrophils by inhibiting the generation of hypochlorous acid.

    Full Text Available Purpose: Pain is one of the most important factors adversely affecting clinical outcomes of operated patients. The present study aims at evaluating effects of preoperative COX2 non-steroidal anti-inflammatory inhibitors on pain mitigation and performance of patients with shoulder rotator cuff tear. Methods: This case-control study was conducted on 60 patients suffering from rotator cuff injury candidate for arthroscopic repair. The patients were classified in two parallel and matched groups. One group (case group was treated using Celecoxib (200mg/12h started 48 hours before surgery and continued for 10 days after operation. In the control group, the placebo was prescribed in the same way. Postoperative pain, side effects, sleep disturbance, and short-term outcomes were compared between two groups using DASH questionnaire. Results: Postoperative pain in the Celecoxib group significantly decreased in comparison with the control one. The difference was statistically meaningful (P<0.001. Well motion ability was seen in 80% of patients of the Celecoxib group. It was 26.6% in the placebo group since pain inhibited them from exercising more motions. In this regard, there was a statistically meaningful difference between these two groups (P=0.02. Sleep disturbance was meaningfully at higher levels in the placebo group (P=0.001. Following up the patients for three months, it was made clear that performance of the Celecoxib group was better than that of the placebo one. Conclusion: COX2 inhibitors are well efficient in patients’ pain management after arthroscopic rotator cuff repair surgery. It results in less life complications, less sleep disturbances, improvement of patients’ short-term clinical outcome, and more quick recovery.

Within the units are short intra­ligand C—Cl⋯π(pym) inter­actions [3.6409 (15) Å]. The units are linked through the bridging N atoms of the pym ligand into a two-dimensional sheet–polymer structure lying parallel to (100) and stabilized by inter-ring π–π inter­actions between the pym ligands [Cg⋯Cg = 3.4199 (17) Å]. Additional inter-unit C—H⋯O and C—H⋯Cg hydrogen-bonding inter­actions between the sheets give an overall three-dimensional structure. PMID:27746945

    In this study, for the first time, 2-aminobenzothiazole monomer was polymerized on Fe3O4 NPs, graphene oxide/Fe3O4 (GO/Fe3O4) and graphene/Fe3O4 (G/Fe3O4) nanocomposites. The synthesized magnetic nanosorbents were characterized by various techniques. The extraction ability of these nanosorbents including Fe3O4, GO/Fe3O4, G/Fe3O4, Fe3O4@poly(2-aminobenzothiazole) (Fe3O4@PABT), GO/Fe3O4@PABT and G/Fe3O4@PABT were compared for dispersive-micro-solid phase extraction of three non-steroidal anti-inflammatory drugs. The results revealed that GO/Fe3O4@PABT nanocomposite demonstrates higher extraction efficiency for naproxen, diclofenac and ibuprofen as selected model analytes. Following the sorption and elution steps, the model analytes were quantified by high performance liquid chromatography-photo diode array detection. Afterwards, a central composite design methodology combined with desirability function approach was applied to find out the optimal experimental conditions. Under the optimized conditions, the limits of detection and linear dynamic ranges were achieved in the range of 0.07-0.3 μg L(-1) and 0.25-2000 μg L(-1), respectively. The percent of extraction recovery was 87.4, 85.5 and 90.5% for naproxen, diclofenac and ibuprofen, respectively. The obtained relative standard deviation (n=5) was 7.2, 5.4 and 6.4% for naproxen, diclofenac and ibuprofen, respectively. Ultimately, this method was employed for urinary monitoring of the target analytes and satisfactory results were obtained.

    Micropropagation through cotyledonary and leaf node and boswellic acid production in stem callus of a woody medicinal endangered tree species Boswellia serrata Roxb. is reported. The response for shoots, roots and callus formation were varied in cotyledonary and leafy nodal explants from in vitro germinated seeds, if inoculated on Murshige and Skoog's (MS) medium fortified with cytokinins and auxins alone or together. A maximum of 8.0 ± 0.1 shoots/cotyledonary node explant and 6.9 ± 0.1 shoots/leafy node explants were produced in 91 and 88 % cultures respectively on medium with 2.5 μM 6-benzyladenine (BA) and 200 mg l(-1) polyvinylpyrrolidone (PVP). Shoots treated with 2.5 μM IBA showed the highest average root number (4.5) and the highest percentage of rooting (89 %). Well rooted plantlets were acclimatized and 76.5 % of the plantlets showed survival upon transfer to field conditions. Randomly amplified polymorphic DNA (RAPD) analysis of the micropropagated plants compared with mother plant revealed true-to-type nature. The four major boswellic acid components in calluses raised from root, stem, cotyledon and leaf explants were analyzed using HPLC. The total content of four boswellic acid components was higher in stem callus obtained on MS with 15.0 μM IAA, 5.0 μM BA and 200 mg l(-1) PVP. The protocol reported can be used for conservation and exploitation of in vitro production of medicinally important non-steroidal anti-inflammatory metabolites of B. serrata.

    The ability of non-steroidal anti-inflammatory drugs (NSAIDs) to injure the small intestine has been well established in humans and animals. Proton pump inhibitors (PPIs) are frequently prescribed to reduce gastric and duodenal injury caused in high-risk patients taking NSAIDs. However, scarce information is available concerning the effects of PPIs on intestinal damage induced by NSAIDs, and the suppression of gastric acid secretion by PPIs is hard to provide any protection against the damage caused by NSAIDs in the small intestine. The present study was designed to examine the effects of intragastric treatment of two PPIs widely used in clinical practice, namely omeprazole and pantoprazole, on the intestinal damage induced by administration of diclofenac in rat. Male SD rats were treated with omeprazole or pantoprazole for 9 days, with concomitant treatment with anti-inflammatory doses of diclofenac on the final 5 days. The anatomical lesion, villous height, the thickness, and the section area of small intestine were quantitatively analyzed. The change of ultrastructural organization was observed. Endotoxin level in blood was measured by photometry. Epidermal growth factor was observed by immunohistochemistry. Omeprazole and pantoprazole didn't decrease the macroscopic and histologic damage induced by diclofenac in the rat's small intestine. In the two PPI groups, villous height was (89.6 ± 11.8 and 92.6 ± 19.3 μm) lower than which of the control group (P thickness became thinning, and the section area became small. LPS levels in the portal blood of omeprazole and pantoprazole were (4.36 ± 1.26 and 4.25 ± 1.17 EU/ml), significantly higher than in controls (P small intestine from the damage induced by diclofenac in the conscious rat. PPIs cannot repair NSAID-induced intestinal damage at least in part because of significant lesion in mechanical barrier function and reduction in epidermal growth factor.

    In subjects with non-steroidal anti-inflammatory drugs (NSAIDs)- exacerbated respiratory disease (NERD) symptoms are triggered by acetyl salicylic acid (ASA) and other strong COX-1 inhibitors, and in some cases by weak COX-1 or by selective COX-2 inhibitors. The mechanism involved is related to prostaglandin pathway inhibition and leukotriene release. Subjects who react to a single NSAID and tolerate others are considered selective responders, and often present urticaria and/or angioedema and anaphylaxis (SNIUAA). An immunological mechanism is implicated in these reactions. However, anecdotal evidence suggests that selective responders who present respiratory airway symptoms may also exist. Our objective was to determine if subjects might develop selective responses to NSAIDs/paracetamol that manifest as upper/lower airways respiratory symptoms. For this purpose, we studied patients reporting asthma and/or rhinitis induced by paracetamol or a single NSAID that tolerated ASA. An allergological evaluation plus controlled challenge with ASA was carried out. If ASA tolerance was found, we proceeded with an oral challenge with the culprit drug. The appearance of symptoms was monitored by a clinical questionnaire and by measuring FEV1 and/or nasal airways volume changes pre and post challenge. From a total of 21 initial cases, we confirmed the appearance of nasal and/or bronchial manifestations in ten, characterized by a significant decrease in FEV1% and/or a decrease in nasal volume cavity after drug administration. All cases tolerated ASA. This shows that ASA tolerant subjects with asthma and/or rhinitis induced by paracetamol or a single NSAID without skin/systemic manifestations exist. Whether these patients represent a new clinical phenotype to be included within the current classification of hypersensitivity reactions to NSAIDs requires further investigation. PMID:27489545

    Full Text Available The objective of this case-control study was to investigate the risk of cardiovascular disease (CVD following non-steroidal anti-inflammatory drug (NSAID use in patients with ankylosing spondylitis (AS. A total of 10,763 new AS patients were identified from the National Taiwan Health Insurance claims database during the period from 1997 to 2008. In all, 421 AS patients with CVD were recruited as cases, and up to 2-fold as many sex- and age-matched controls were selected. Logistic regression models were used to estimate the odds ratio (OR between NSAID use and CVD incidence. The medication possession rate (MPR was used to evaluate NSAID exposure during the study period. AS patients had increased risk of CVD (OR, 1.68; 95% confidence interval (CI, 1.57 to 1.80. Among frequent (MPR≥80% COX II users, the risks for all types of CVD were ten times lower than those among non-users at 24 months (OR, 0.08; 95% CI, 0.01 to 0.92. Among frequent NSAID users, the risks of major adverse cardiac event (MACE were significantly lower at 12 months (OR, 0.23; 95% CI, 0.07 to 0.76--a trend showing that longer exposure correlated with lower risk. Regarding non-frequent NSAID users (MPR<80%, short-term exposure did carry higher risk (for 6 months: OR, 1.41; 95% CI, 1.07 to 1.86, but after 12 months, the risk no longer existed. We conclude that long-term frequent use of NSAIDs might protect AS patients from CVD; however, NSAIDs still carried higher short-term risk in the non-frequent users.

    Ebrotidine (N-[(E)-[[2-[[[2-[(diaminomethylene)amino]- 4-thiazolyl]methyl]thio]ethyl]amino]methylene]-4-bromo-benzenesulfonamid e, CAS 100981-43-9, FI-3542) is a new H2-receptor antagonist providing a new therapy for the prevention and healing of non-steroidal anti-inflammatory drugs-induced gastroduodenal lesions. Carbonic anhydrase is a zinc enzyme, and its isozyme (carbonic anhydrase II) in parietal cells plays a central role in HCl secretion. The effects of ebrotidine on carbonic anhydrase in human subjects are reported. Eighteen healthy volunteers were distributed in 3 equal subgroups and treated for 10 days as follows: ebrotidine 800 mg/d p.o. (Group A); indometacin 4 mg/kg/d p.o. in 3 divided doses (Group B); ebrotidine 800 mg/d p.o. plus indometacin 4 mg/kg/d p.o. (Group C). Assessment of the enzymatic activity of carbonic anhydrase was based on the colorimetric method of changing pH with the stopped-flow technique. In group A, ebrotidine reduced total gastric mucosal carbonic anhydrase activity by 62%; in group B, indometacin increased carbonic anhydrase activity in gastric mucosa by 138%; in group C, the combined treatment with ebrotidine plus indometacin decreased gastric mucosal carbonic anhydrase activity by 38%. The present study shows that, unlike ranitidine, ebrotidine, a competitive H2-receptor antagonist, is also a non-competitive inhibitor of carbonic anhydrase I and II. By antagonizing the activating effects of indometacin on gastric mucosal carbonic anhydrase, ebrotidine prevents mucosal lesions caused by anti-inflammatory drugs.

    The purpose of this study is to compare a combination of interferon (IFN)-alpha2a (Roferon) + Tenoxicam with IFN-alpha2a alone in the treatment of chronic hepatitis C. This prospective, randomized double-blind study included 149 patients, all of whom were diagnosed with active chronic hepatitis C but non-cirrhotic (ALT > or = 1.5 upper limit of normal, anti-hepatitis C virus (HCV) positive by enzyme-linked immunosorbant assay2 and RIBA3). The patients were randomized in two groups, as follows: G1 (n = 76): IFNalpha2a 3 million units times per week during 6 months + placebo; and G2 (n = 73): IFNalpha2a 3 million units three times per week + Tenoxicam (20 mg/day) during 6 months. Alanine aminotransferase (ALT) and HCV RNA were determined before and at months 6 and 12 of treatment. 2'5' oligoadenylate synthetase activity (2'5' AS) was dosed in mononuclear cells before and at 3-month treatment intervals in 28 patients. Liver biopsy was performed before and 6 months after the end of therapy. Parameters were similar before therapy for both groups. Biochemical and virological responses were similar for both groups at month 6 (49.3% vs. 42.9% and 43.3% vs. 38.3%, respectively) and month 12 (28.3% vs. 23.8% and 17.2% vs. 17.5%, respectively). HCV RNA level significantly decreased in both groups at month 6, with no difference whatever the therapy; however, the HCV RNA level returned to initial values at month 12 and was the only significant prognostic factor of a sustained response. No peak of 2'5' AS activity was observed during treatment in patients with dual therapy. A histological improvement was also noted in both groups without difference, regardless of therapy. The percentage of adverse events was identical for both groups. Paracetamol intake, assessed in 80 patients, was 49.1 g per 6 months in the G1 group and 22.5 g per 6 months in the G2 group (not significant). In conclusion, the non-steroid anti-inflammatory drug, Tenoxicam, does not increase IFNalpha efficacy in

    This study describes for the first time results of a (19)F-MRS study on humans exposed to the fluorinated non-steroidal anti-inflammatory drug niflumic acid. The accumulation and elimination of this commercially available selective prostaglandin synthase inhibitor is studied after an oral bolus in the human liver, in blood plasma and in urine samples. The in vivo spectra of the liver display two resonances with a similar increase in signal intensity during the investigation period of 240 min. One resonance refers to the parent compound niflumic acid (P), whereas the second resonance corresponds to a metabolite (M1) formed by the biotransformation by liver enzymes. The spectroscopic comparison with model compounds suggests 4'-hydroxyniflumic acid as the metabolite. During the entire experiment the concentration ratios of these resonances (P/M1) ranged between 0.7 and 0.9, indicating a high metabolite concentration most probably due to an efficient first pass metabolism. Both resonances (P, M1) were observed in the in vitro study of the blood plasma samples after plasma protein denaturation. However, in comparison to the liver spectra, the amount of the metabolite M1 is very small with a P/M1-ratio of 36.6 after 90 min and 16.1 after the end of measurement. This finding suggests an efficient biliary excretion of the metabolite M1, which bypasses the blood circulation system. Both resonances are also identified in the native urine samples. The signal intensity of the parent compound dominates the spectra of all urine samples, whereas the signal intensity of M1 increases slowly reaching a similar value to the parent compound P at the end of the measurement. This observation demonstrates an effective renal elimination of niflumic acid and suggests the existence of an enterohepatic circuit with a re-entry mechanism for the biliary excreted metabolite M1. In the urine spectra, an additional metabolite M2 is found. This resonance exhibits a low but constant signal

    AIM: This study investigated the mechanisms of protection afforded by the proton pump inhibitor lansoprazole against gastric injury induced by different non-steroidal antiinflammatory drugs (NSAIDs) in rats.METHODS: Male Sprague-Dawley rats were orally treated with indomethacin (100 μmol/kg), diclofenac (60 μmol/kg),piroxicam (150 μmol/kg) or ketoprofen (150 μmol/kg).Thirty minutes before NSAIDs, animals were orally treated with lansoprazole 18 or 90 μmol/kg. Four hours after the end of treatments, the following parameters were assessed: gastric mucosal PGE2, malondialdehyde (MDA), myeloperoxidase (MPO) or non-proteic sulfhydryl compounds (GSH) levels; reverse transcription-polymerase chain reaction (RT-PCR) of mucosal COX-2 mRNA; gastric acid secretion in pylorus-ligated animals; in vitro effects of lansoprazole (1-300 μmol/L) on the oxidation of low density lipoproteins (LDLs) induced by copper sulphate.RESULTS: All NSAIDs elicited mucosal necrotic lesions which were associated with neutrophil infiltration and reduction of PGE2 levels. Increments of MPO and MDA contents, as well as a decrease in GSH levels were detected in the gastric mucosa of indomethacin- or piroxicam-treated animals. Indomethacin enhanced mucosal cyclooxygenase-2 expression, while not affecting cyclooxygenase-1. At the oral dose of 18 μmol/kg lansoprazole partly counteracted diclofenac-induced mucosal damage, whereas at 90 μmol/kg it markedly prevented injuries evoked by all test NSAIDs. Lansoprazole at 90 μmol/kg reversed also the effects of NSAIDs on MPO, MDA and GSH mucosal contents, without interfering with the decrease in PGE2 levels or indomethacin-induced cyclooxygenase-2 expression. However, both lansoprazole doses markedly inhibited acid secretion in pylorus-ligated rats. Lansoprazole concentration-dependently reduced the oxidation of LDLs in vitro.CONCLUSION: These results suggest that, besides the inhibition of acid secretion, lansoprazole protection against NSAID

  15. Crystal structures of three classes of non-steroidal anti-inflammatory drugs in complex with aldo-keto reductase 1C3.

    Full Text Available Aldo-keto reductase 1C3 (AKR1C3 catalyses the NADPH dependent reduction of carbonyl groups in a number of important steroid and prostanoid molecules. The enzyme is also over-expressed in prostate and breast cancer and its expression is correlated with the aggressiveness of the disease. The steroid products of AKR1C3 catalysis are important in proliferative signalling of hormone-responsive cells, while the prostanoid products promote prostaglandin-dependent proliferative pathways. In these ways, AKR1C3 contributes to tumour development and maintenance, and suggest that inhibition of AKR1C3 activity is an attractive target for the development of new anti-cancer therapies. Non-steroidal anti-inflammatory drugs (NSAIDs are one well-known class of compounds that inhibits AKR1C3, yet crystal structures have only been determined for this enzyme with flufenamic acid, indomethacin, and closely related analogues bound. While the flufenamic acid and indomethacin structures have been used to design novel inhibitors, they provide only limited coverage of the NSAIDs that inhibit AKR1C3 and that may be used for the development of new AKR1C3 targeted drugs. To understand how other NSAIDs bind to AKR1C3, we have determined ten crystal structures of AKR1C3 complexes that cover three different classes of NSAID, N-phenylanthranilic acids (meclofenamic acid, mefenamic acid, arylpropionic acids (flurbiprofen, ibuprofen, naproxen, and indomethacin analogues (indomethacin, sulindac, zomepirac. The N-phenylanthranilic and arylpropionic acids bind to common sites including the enzyme catalytic centre and a constitutive active site pocket, with the arylpropionic acids probing the constitutive pocket more effectively. By contrast, indomethacin and the indomethacin analogues sulindac and zomepirac, display three distinctly different binding modes that explain their relative inhibition of the AKR1C family members. This new data from ten crystal structures greatly broadens

    Full Text Available From year 1997 the Requena Hospital Pharmacy Service maintain a program of detection and prevention of drugs-related problems hospital income (DRPI. The program is coordinated with the Primary Care Pharmacy Service for the establishment of the preventive measures. The DRPI program establishes feedback, collective and/or individualized, on the agents of health of the Health Area and on the population in general, according to the cases, as it bases for the prevention of DRPIs. Methods: The detection of IDRP is made by means of revision of the diagnoses gathered in the admission book of the Emergency Department and the HIGIA database. Clinical records of the patients are retrospectively analyzed. Medical criteria, specifically gathered in clinical history, are accepted for the imputability establishment. Results: In period 1997-2003, 195 drug-related high digestive hemorrhage hospital income (HDH have been detected: 188 by non-steroidal anti-inflammatory drugs (NSAID, in two cases the NSAID could not settle down cause, 3 by ticlopidine, 3 by metamizole and 1 by clopidogrel. In 45 cases (23% the involved medicine was over the counter (OTC, 58 cases were related to low doses aspirin (AAS, 15 cases related to the association of NSAIDs or NSAIDs with low doses AAS and 70 cases were produced by non-aspirin-NSAIDs or non-OTC-AAS to doses of 500mg. 80% of the cases of HDH by AAS to low doses took place in patients of 69 years old or older. In 85% of the cases of HDH by non-aspirin- NSAID or non-OTC-AAS of 500mg with gastro-protection criteria this had not been used. In the three cases of HDH by metamizole patients were older than 80 years and with HDH antecedents. Conclusions: The low use of gastroprotection between the affected population of HDH by NSAIDs in spite of the existence of clear factors of risk concludes. Gastroprotection in patients dealt with low doses AAS and equal or greater age about 69 years although the age were the only factor of risk

    Background Non-steroidal anti-inflammatory drugs (NSAIDs) are among the most commonly used pharmaceutical agents worldwide. NSAIDs are considered nephrotoxic and should therefore be used with caution or be avoided completely in high risk patients, such as chronic kidney disease (CKD) patients. Objective This study aimed to investigate the prescribing of NSAIDs in CKD patients in order to generate awareness and improve the outcome of these patients. Setting The study was conducted using medicine claims data in the private health sector of South Africa. Method A descriptive, quantitative study was performed, using retrospective data obtained from a Pharmaceutical Benefit Management company. Data from 1 January 2009 to 31 December 2013 were analysed. The study population consisted of all patients with an ICD-10 code for a CKD (N18), in association with a paid claim for an NSAID. Main outcome measure The stratification of NSAID prescribing volume among the CKD population in terms of gender, age, NSAID type, dosage and prescriber type. Results The prescribing of NSAIDs in CKD patients varied between 26 and 40 % over the 5 year study period. No association between gender and CKD patients who received NSAIDs versus those who did not was found, with p > 0.05 and Cramer's V < 0.1 for each year of the study. The association between age groups and CKD patients who received NSAIDs versus those who did not was statistically significant, but practically weak (p < 0.05; Cramer's V ≥ 0.1). Most NSAID prescriptions (52-63 %) were for patients aged 35-64 years. Diclofenac (34.25 %) was the single most frequently prescribed NSAID, but the COX-2-inhibitors (celecoxib, meloxicam and etoricoxib) were the preferred NSAID class to be prescribed. The majority (61.6 %) of the NSAIDs were prescribed by general medical practitioners in dosages meeting and even exceeding the recommended daily dosage of patients with normal kidney function. Conclusions Even though NSAIDs are

    Bruus, Marianne; Dupont, Yoko Luise; Grant, Ruth;

    Både i Danmark og andre steder er der observeret en nedgang i de insekter, der bestøver landmandens afgrøder og de vilde planter. Tilbagegangen falder sammen med, at landbrugsdriften er blevet mere intensiv, og anvendelsen af pesticider er øget. Vi ved imidlertid ikke, hvilken rolle pesticiderne...... vigtige for bestøvningen af fx kløver og mange vilde planter. Da humlebier og andre vilde bier har en anden adfærd og placerer deres reder andre steder end honningbierne, er det ikke givet, at de er beskyttet mod pesticideksponering, selv om honningbierne er. I pilotprojektet ”Betydningen af pesticider...... for forekomsten af vilde bier og honningbier” har Aarhus Universitet på to landbrugsbedrifter gennemført en indledende undersøgelse af, om humlebier udsættes for pesticider i danske landbrugsområder.

    Wagner, Michael

    Det amerikanske automobilfirma Ford Motor Company med hovedkvarter i Detroit begyndte at drive forretning i Danmark omkring 1906. De første aktiviteter blev konsolideret samme år ved udnævnelsen af motorforhandleren F. Bülow & Co. til salgsagent i Danmark og importør af Ford automobiler til det...... skandinaviske marked. Dermed havde Ford tidligt fået et stærkt fodfæste i Nordeuropa, som udviklingen i salget af Ford autobiler de næste årtier til fulde skulle demonstrere. Ford Motor Company er i dag den fjerde største bilproducent på verdensmarkedet, men går man tilbage til 1920'rne var selskabet førende...... med en markedsandel på mere end 50%. En position som Ford måtte afgive til General Motors i løbet af årtiet. I Danmark var mere end hvert andet indregistreret automobil i 1930 antageligt af mærket Ford, og helt frem til verdenskrigens udbrud var Ford Motor Company et brand, som spillede en meget...

    The structural features of copper(II), nickel(II), cobalt(II) and zinc(II) complexes with the antimicrobial drugs quinolones and non-steroidal anti-inflammatory drugs (NSAIDs) as ligands are discussed. The binding properties of these complexes to biomolecules (calf-thymus DNA, bovine or human serum albumin) are presented and evaluated. The biological activity (antimicrobial, antioxidant and antiproliferative) of selected complexes is investigated. Further perspectives concerning the synthesis and the biological activity of novel complexes with quinolones or NSAIDs attractive to synthetic chemists, biochemists and/or biologists are presented.

    2010-10-01

    evaluation of gene expression levels of IL-1beta and PGE2 in gingival tissue of periodontal patients was applied. Results: Statistically significant differences were found between additional Aulin® therapy group and conventional therapy group. Received correlative coefficient with Spearman analysis was respectively t = -0.72 (p< 0,05 for IL-1beta and t = 0.81(p<0,05 for PGE2. The negative values of ddCt in test group reveal lower level of inhibition of gene expression. The comparative analysis of the collected data demonstrates fewer differences between both groups. The deviations in gene expression levels of IL -1beta and PGE2 are higher in the patients treated with adjunctive medication with Aulin®. Conclusion: This study confirms the effectiveness of non-surgical therapy in moderate and severe periodontitis. Additional use of non-steroidal anti-inflammatory agent Aulin® results in higher inhibition of the pro-inflammatory cytokines IL-1beta and PGE2. This data may be the base for modifying the conventional non-surgical therapy by including anti-inflammatory agents in the treatment of chronic periodontitis.

  17. In vitro evaluation of the effects of anti-fungals, benzodiazepines and non-steroidal anti-inflammatory drugs on the glucuronidation of 19-norandrosterone: implications on doping control analysis.

    Palermo, Amelia; Alessi, Beatrice; Botrè, Francesco; de la Torre, Xavier; Fiacco, Ilaria; Mazzarino, Monica

    2016-09-01

    We have studied whether the phase II metabolism of 19-norandrosterone, the most representative metabolite of 19-nortestosterone (nandrolone), can be altered in the presence of other drugs that are not presently included on the Prohibited List of the World Anti-Doping Agency. In detail, we have evaluated the effect of non-prohibited drugs belonging to the classes of anti-fungals, benzodiazepines, and non-steroidal anti-inflammatory drugs on the glucuronidation of 19-norandrosterone. In vitro assays based on the use of either pooled human liver microsomes or specific recombinant isoforms of uridine diphosphoglucuronosyl-transferase were designed and performed to monitor the formation of 19-norandrosterone glucuronide from 19-norandrosterone. Determination of 19-norandrosterone (free and conjugated fraction) was performed by gas chromatography - mass spectrometry after sample pretreatment consisting of an enzymatic hydrolysis (performed only for the conjugated fraction), liquid/liquid extraction with tert-butylmethyl ether, and derivatization to form the trimethylsilyl derivative. In parallel, a method based on reversed-phase liquid chromatography coupled to tandem mass spectrometry in positive electrospray ionization with acquisition in selected reaction monitoring mode was also developed to identify the non-prohibited drugs considered in this study. Incubation experiments have preliminarily shown that the glucuronidation of 19-norandrosterone is principally carried out by UGT2B7 (39%) and UGT2B17 (31%). Inhibition studies have shown that the yield of the glucuronidation reaction is reduced in the presence of the anti-fungals itraconazole, ketoconazole, and miconazole, of the benzodiazepine triazolam and of the non-steroidal anti-inflammatory drugs diclofenac and ibuprofen, while no alteration was recorded in the presence of all other compounds considered in this study.

  16. Barrierer for ibrugtagning af videooptaget universitetsundervisning

    Directory of Open Access Journals (Sweden)

    2009-06-01

    Full Text Available Danmarks Pædagogiske Universitetsskole ved Aarhus Universitet har siden 2006 eksperimenteret med systematisk videooptagelse og -streamning af undervisning på udvalgte kandidat- og masteruddannelser. De studerende er begejstrede for denne praksis og de muligheder, dette giver de studerende for at understøtte deres læring. Men selvom de studerende har vist sig at bruge den videostreamede undervisning på en endog særdeles hensigtsmæssig måde, har der, både blandt studerende og især blandt underviserne, været modstand mod dels overhovedet at optage, dels at gøre optagelserne af undervisningen offentligt tilgængelige for studerende og andre interesserede. Der kan således iagttages nogle barrierer i forhold til ibrugtagning af videooptaget undervisning på universitetsniveau, idet underviserne for en umiddelbar betragtning tilsyneladende for det første har nogle forbehold af psykologisk, for det andet af juridisk karakter og for det tredje af organisatorisk art. Et af de centrale spørgsmål i denne forbindelse synes således at være, om optagelse af undervisning muliggør en ledelsesmæssig evaluering af den enkelte undervisers undervisningspraksis. Et andet centralt spørgsmål er tilsyneladende, om optagelse af undervisningen, der muliggør genbrug, gør underviserne overflødige. Forfatterne til denne artikel er imidlertid af den opfattelse, at undervisernes modstand følger af en anden, og mere grundlæggende, diskrepans, nemlig diskrepansen mellem det at forske og det at undervise. Efter en indledende begrebsafklaring, præsenterer forfatterne i denne artikel erfaringerne med tilbud af videostreamet og podcastet universitetsundervisning til studerende på Danmarks Pædagogiske Universitetsskole med henblik på en diskussion af de potentialer og især de barrierer, der kan iagttages i forhold til en mere systematisk, large-scale brug af castet universitetsundervisning. I forlængelse heraf formulerer forfatterne desuden en mulig

    temadagen præsenteres nye resultater og metoder til at vurdere stress hos mink. I en metode måles koncentrationen af nedbrydningsprodukter af hormonet cortisol i gødning fra mink. Der er en række fordele ved denne metode, frem for blodprøvetagning. Forsøg viste, at hovedparten af cortisol udskilles i fæces...... (83 %) frem for i urin (17 %), samt at omsætningen af radioaktivt mærket cortisol ikke er forskellig mellem mink med hhv. lav og høj forekomst af stereotypi. Denne viden kan bruges til bedre at forstå koblingen f.eks. unormal adfærd og stress hos mink.......Sammendrag Stress indgår som et element ved vurdering af dyrevelfærd. Endvidere kan stress mål anvendes i undersøgelser, hvor forskellige typer af avl, burmiljø og pasning af mink sammenlignes. Men hvad er stress egentlig og hvordan måles det?

    2016-01-01

    Full Text Available I denne artikel undersøger vi potentialerne for at lære matematik gennem programmering af robotter. Vi foreslår en model med tre indbyrdes afhængige læringspotentialer, som programmering fordrer. Det omfatter elevens evne til at; (1 tænke i algoritmer, (2 producere viden og artefakter gennem brug af matematik og (3 foretage abstraktion og indkapsling. Programmering er blevet en del af grundskolens læringsmål i flere lande. I Danmark er programmering et læringsmål i forenklede fælles mål for Fysik/Kemi og desuden en del af den nationale undervisningsvejledning for matematik. En analyse af potentialerne i at anvende programmering i forbindelse med disse fag er derfor væsentlig. I denne artikel fokuserer vi på samspillet mellem matematik og programmering gennem litteraturstudier og analyse af empiriske situationer fra undervisning i programmering af LEGO Mindstorms. Teoretisk anvendes den instrumentelle tilgang til teknologi i matematikundervisning. Analysen viser en række måder, hvorpå didaktisk opmærksomhed på epistemisk forhandling kan understøtte læring af matematik gennem programmering.

    2006-01-01

    The inhibitory potencies of non-steroidal anti-inflammatory drugs (NSAIDs) on UDP-glucuronosyltransferase (UGT) 1A9 activity were investigated in recombinant human UGT1A9 using 4-methylumbelliferone (4-MU) as a substrate for glucuronidation. 4-MU glucuronidation (4-MUG) showed Michaelis-Menten kinetics with a Km value of 6.7 microM. The inhibitory effects of the following seven NSAIDs were investigated: acetaminophen, diclofenac, diflunisal, indomethacin, ketoprofen, naproxen and niflumic acid. Niflumic acid had the most potent inhibitory effect on 4-MUG with an IC50 value of 0.0341 microM. The IC50 values of diflunisal, diclofenac and indomethacin were 1.31, 24.2, and 34.1 microM, respectively, while acetaminophen, ketoprofen and naproxen showed less potent inhibition. Niflumic acid, diflunisal, diclofenac and indomethacin inhibited 4-MUG competitively with Ki values of 0.0275, 0.710, 53.3 and 69.9 microM, respectively, being similar to each IC50 value. In conclusion, of the seven NSAIDs investigated, niflumic acid was the most potent inhibitor of recombinant UGT1A9 via 4-MUG in a competitive manner.

  4. The pharmacology and activity of non-steroidal anti-inflammatory drugs (NSAIDs: a review of their use as an adjuvant treatment in patients with HBV and HCV chronic hepatitis

    Directory of Open Access Journals (Sweden)

    Sirio Fiorino

    2013-03-01

    Full Text Available Introduction: Different DNA and RNA viruses exploit common strategies to support their persistence and replication in infected individuals. In particular, the hepatitis B virus (HBV and the hepatitis C virus (HCV cause major health problems worldwide. These pathogens exert an immunosuppressive role by inducing the persistent activation of cyclooxygenase-2 (COX-2 and an increased synthesis of prostaglandin E2 (PGE2. The suppression of this proinflammatory network by non-steroidal anti-inflammatory drugs (NSAIDs has been proposed as a therapeutic approach to decrease viral replication. Materials and methods: In this review, the role of inflammation in the support of viral replication and NSAIDs and ketoprofen pharmacology are briefly discussed. In addition, studies that have investigated the use of NSAIDs for the treatment of HBV and HCV chronic hepatitis, which were identified by a systematic literature search of PubMed and MEDLINE, are reported. Results: To date, pegylated-interferon (PEG-IFN and/or nucleot(side analogues and PEG-IFN and ribavirin remain the standard therapy for HBV and HCV chronic hepatitis, respectively. Discussion: The use of NSAIDs in patients with chronic viral hepatitis has only a ‘‘historical’’ interest. Nevertheless, the possible usefulness of ketoprofen with PEG-IFN and ribavirin for HCVinfected patients, non-responders to standard therapy or with genotype 1, should be evaluated in future clinical studies.

    The identification of a safe and reliable alternative for patients with non-steroidal anti-inflammatory drug (NSAID)-induced urticaria/angioedema is a frequent problem for dermatologists and other practitioners. Cyclooxygenase-2 (COX-2) inhibitors have been reported to be safe for NSAID-intolerant patients from the US and Europe but not all of them have yet been approved for use in Japan. It was our objective to investigate the clinical manifestations of oral NSAID challenges in Japanese patients with histories of urticaria and/or angioedema after the intake of NSAIDs and to find safe alternative drugs, including COX-2 inhibitors and a basic anti-inflammatory drug. Twenty subjects suspected NSAID-induced urticaria/angioedema from histories were included in a double-blind or single-blind, placebo-controlled oral challenge protocol using NSAIDs. Skin prick tests using NSAIDs, which were dissolved in saline, were conducted. The mean age of the patients was 37.3 years; 14 patients were female. The results of other challenge tests showed that the most frequently intolerated drugs was loxoprofen (100%), followed by acetyl salicylic (94.4%), etodolac (53.3%), dicrofenac (50%), acetaminophen (38.5%), meloxicam (33%), and tiaramide (21.4%). Urticaria and angioedema were induced after aspirin intake in 83.3% and 22.2% of patients, respectively, whereas an asthmatic response was seen in 5.6%. Skin prick tests with NSAIDs were 100% negative. This study showed that among the NSAIDs that are available in Japan and that were investigated in this study, tiaramide, which does not inhibit COX, is the relatively safe alternative drug for Japanese patients with NSAID-induced urtiacaria and/or angioedema. Furthermore, meloxicam seems to be better tolerated than etodolac between two selective COX-2 inhibitors.

    Objectives To assess whether a double therapy combination consisting of diuretics, angiotensin converting enzyme inhibitors, or angiotensin receptor blockers with addition of non-steroidal anti-inflammatory drugs (NSAIDs) and the triple therapy combination of two of the aforementioned antihypertensive drugs to which NSAIDs are added are associated with an increased risk of acute kidney injury. Design Retrospective cohort study using nested case-control analysis. Setting General practices contributing data to the UK Clinical Practice Research Datalink linked to the Hospital Episodes Statistics database. Participants A cohort of 487 372 users of antihypertensive drugs. Main outcome measures Rate ratios with 95% confidence intervals of acute kidney injury associated with current use of double and triple therapy combinations of antihypertensive drugs with NSAIDs. Results During a mean follow-up of 5.9 (SD 3.4) years, 2215 cases of acute kidney injury were identified (incidence rate 7/10 000 person years). Overall, current use of a double therapy combination containing either diuretics or angiotensin converting enzyme inhibitors or angiotensin receptor blockers with NSAIDs was not associated with an increased rate of acute kidney injury. In contrast, current use of a triple therapy combination was associated with an increased rate of acute kidney injury (rate ratio 1.31, 95% confidence interval 1.12 to 1.53). In secondary analyses, the highest risk was observed in the first 30 days of use (rate ratio 1.82, 1.35 to 2.46). Conclusions A triple therapy combination consisting of diuretics with angiotensin converting enzyme inhibitors or angiotensin receptor blockers and NSAIDs was associated with an increased risk of acute kidney injury. The risk was greatest at the start of treatment. Although antihypertensive drugs have cardiovascular benefits, vigilance may be warranted when they are used concurrently with NSAIDs. PMID:23299844

    Human hair growth can be monitored for several months after the transplantation of scalp samples from men with androgen-dependent alopecia on to female nude mice. Hair production from balding sites has been shown to be inhibited in testosterone-conditioned nude mice. We used this recently reported model to study the effect of a new non-steroidal antiandrogen-RU58841-on human hair growth. Twenty productive scalp grafts from balding men were maintained for 8 months after grafting on to nude mice, and hair production was monitored monthly for 6 months. All mice were conditioned by the topical application of testosterone (testosterone propionate, 300 micrograms in 10 microL; 5 days/week) on the non-grafted flank. The scalp samples were divided equally according to the estimated hair production potential, which was based on the amount of hair present on the scalp samples before grafting. Each of the two equal groups of grafts was further allocated at random to be treated topically (5 days/week) with blinded solutions of either RU58841 1% in ethanol, or ethanol as a control. Twenty-eight active follicles appeared on the 10 control grafts. Among them only two follicles (7%) initiated a second hair cycle. However, the 10 RU58841-treated grafts bore a total of 29 active follicles, and eight of them (28%) showed a second cycle. The values for the linear hair growth rates (LHGR) were significantly (P Recycling and increased LHGR indicate a positive action for RU58841 on human hair growth from balding samples grafted on to testosterone-conditioned nude mice, and encourage a clinical trial to evaluate its potential in the treatment of androgen-dependent alopecia.

  13. Molecular interactions between some non-steroidal anti-inflammatory drugs (NSAID's) and bovine (BSA) or human (HSA) serum albumin estimated by means of isothermal titration calorimetry (ITC) and frontal analysis capillary electrophoresis (FA/CE).

    The interactions between some non-steroidal anti-inflammatory drugs, NSAIDs, (naproxen, ibuprofen and flurbiprofen) and bovine (BSA) or human (HSA) serum albumin have been examined by means of two complementary techniques, isothermal titration calorimetry (ITC) and frontal analysis/capillary electrophoresis (FA/CE). It can be concluded that ITC is able to measure with high precision the strongest drug-albumin interactions but the higher order interactions can be better determined by means of FA/CE. Then, the combination of both techniques leads to a complete evaluation of the binding profiles between the selected NSAIDs and both kind of albumin proteins. When BSA is the binding protein, the NSAIDs show a strong primary interaction (binding constants: 1.5 × 10(7), 8 × 10(5) and 2 × 10(6) M(-1) for naproxen, ibuprofen and flurbiprofen, respectively), and also lower affinity interactions of the same order for the three anti-inflammatories (about 1.7 × 10(4) M(-1)). By contrast, when HSA is the binding protein two consecutive interactions can be observed by ITC for naproxen (9 × 10(5) and 7 × 10(4) M(-1)) and flurbiprofen (5 × 10(6) and 6 × 10(4) M(-1)) whereas only one is shown for ibuprofen (9 × 10(5) M(-1)). Measurements by FA/CE show a single interaction for each drug being the ones of naproxen and flurbiprofen the same that those evaluated by ITC as the second interaction events. Then, the ability of both techniques as suitable complementary tools to establish the whole interaction NSAIDs-albumin profile is experimentally demonstrated and allows foreseeing suitable strategies to establish the complete drug-protein binding profile. In addition, for the interactions analyzed by means of ITC, the thermodynamic signature is established and the relative contributions of the enthalpic and entropic terms discussed.

  14. Aging Enables Ca2+ Overload and Apoptosis Induced by Amyloid-β Oligomers in Rat Hippocampal Neurons: Neuroprotection by Non-Steroidal Anti-Inflammatory Drugs and R-Flurbiprofen in Aging Neurons.

    The most important risk factor for Alzheimer's disease (AD) is aging. Neurotoxicity in AD has been linked to dyshomeostasis of intracellular Ca2+ induced by small aggregates of the amyloid-β peptide 1-42 (Aβ42 oligomers). However, how aging influences susceptibility to neurotoxicity induced by Aβ42 oligomers is unknown. In this study, we used long-term cultures of rat hippocampal neurons, a model of neuronal in vitro aging, to investigate the contribution of aging to Ca2+ dishomeostasis and neuron cell death induced by Aβ42 oligomers. In addition, we tested whether non-steroidal anti-inflammatory drugs (NSAIDs) and R-flurbiprofen prevent apoptosis acting on subcellular Ca2+ in aged neurons. We found that Aβ42 oligomers have no effect on young hippocampal neurons cultured for 2 days in vitro (2 DIV). However, they promoted apoptosis modestly in mature neurons (8 DIV) and these effects increased dramatically after 13 DIV, when neurons display many hallmarks of in vivo aging. Consistently, cytosolic and mitochondrial Ca2+ responses induced by Aβ42 oligomers increased dramatically with culture age. At low concentrations, NSAIDs and the enantiomer R-flurbiprofen lacking anti-inflammatory activity prevent Ca2+ overload and neuron cell death induced by Aβ42 oligomers in aged neurons. However, at high concentrations R-flurbiprofen induces apoptosis. Thus, Aβ42 oligomers promote Ca2+ overload and neuron cell death only in aged rat hippocampal neurons. These effects are prevented by low concentrations of NSAIDs and R-flurbiprofen acting on mitochondrial Ca2+ overload.

    Non-steroidal anti-inflammatory drugs (NSAIDs) have been suggested as the potential new class of preventive or therapeutic antitumor agents. The aim of the present study was to evaluate the antitumor activity of the novel NSAID, CG100649. CG100649 is a novel NSAID dual inhibitor for COX-2 and carbonic anhydrase (CA)-I/-II. In the present study, we investigated the alternative mechanism by which CG100649 mediated suppression of the colon cancer growth and development. The anchorage‑dependent and -independent clonogenic assay showed that CG100649 inhibited the clonogenicity of human colon cancer cells. The flow cytometric analysis showed that CG100649 induced the G2/M cell cycle arrest in colon cancer cells. Animal studies showed that CG100649 inhibited the tumor growth in colon cancer xenograft in nude mice. Furthermore, quantitative PCR and FACS analysis demonstrated that CG100649 upregulated the expression of TNF-related apoptosis-inducing ligand (TRAIL) receptors (DR4 and DR5) but decreased the expression of decoy receptors (DcR1 and DcR2) in colon cancer cells. The results showed that CG100649 treatment sensitized TRAIL‑mediated growth suppression and apoptotic cell death. The combination treatment resulted in significant repression of the intestinal polyp formation in APCmin/+ mice. Our data clearly demonstrated that CG100649 contains preventive and therapeutic activity for colon cancer. The present study may be useful for identification of the potential benefit of the NSAID CG100649, for the achievement of a better treatment response in colon cancer.

  16. Use of non-steroidal anti-inflammatory drugs that elevate cardiovascular risk: an examination of sales and essential medicines lists in low-, middle-, and high-income countries.

    Full Text Available BACKGROUND: Certain non-steroidal anti-inflammatory drugs (NSAIDs (e.g., rofecoxib [Vioxx] increase the risk of heart attack and stroke and should be avoided in patients at high risk of cardiovascular events. Rates of cardiovascular disease are high and rising in many low- and middle-income countries. We studied the extent to which evidence on cardiovascular risk with NSAIDs has translated into guidance and sales in 15 countries. METHODS AND FINDINGS: Data on the relative risk (RR of cardiovascular events with individual NSAIDs were derived from meta-analyses of randomised trials and controlled observational studies. Listing of individual NSAIDs on Essential Medicines Lists (EMLs was obtained from the World Health Organization. NSAID sales or prescription data for 15 low-, middle-, and high-income countries were obtained from Intercontinental Medical Statistics Health (IMS Health or national prescription pricing audit (in the case of England and Canada. Three drugs (rofecoxib, diclofenac, etoricoxib ranked consistently highest in terms of cardiovascular risk compared with nonuse. Naproxen was associated with a low risk. Diclofenac was listed on 74 national EMLs, naproxen on just 27. Rofecoxib use was not documented in any country. Diclofenac and etoricoxib accounted for one-third of total NSAID usage across the 15 countries (median 33.2%, range 14.7-58.7%. This proportion did not vary between low- and high-income countries. Diclofenac was by far the most commonly used NSAID, with a market share close to that of the next three most popular drugs combined. Naproxen had an average market share of less than 10%. CONCLUSIONS: Listing of NSAIDs on national EMLs should take account of cardiovascular risk, with preference given to low risk drugs. Diclofenac has a risk very similar to rofecoxib, which was withdrawn from worldwide markets owing to cardiovascular toxicity. Diclofenac should be removed from EMLs.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used as analgesic and anti-rheumatic drugs, and they are often misused. A gas chromatographic-mass spectrometric (GC-MS) screening procedure was developed for their detection in urine as part of a systematic toxicological analysis procedure for acidic drugs and poisons after extractive methylation. The compounds were separated by capillary GC and identified by computerized MS in the full-scan mode. Using mass chromatography with the ions m/z 119, 135, 139, 152, 165, 229, 244, 266, 272, and 326, the possible presence of NSAIDs and their metabolites could be indicated. The identity of positive signals in such mass chromatograms was confirmed by comparison of the peaks underlying full mass spectra with the reference spectra recorded during this study. This method allowed the detection of therapeutic concentrations of acemetacin, acetaminophen (paracetamol), acetylsalicylic acid, diclofenac, diflunisal, etodolac, fenbufen, fenoprofen, flufenamic acid, flurbiprofen, ibuprofen, indometacin, kebuzone, ketoprofen, lonazolac, meclofenamic acid, mefenamic acid, mofebutazone, naproxen, niflumic acid, phenylbutazone, suxibuzone, tiaprofenic acid, tolfenamic acid, and tolmetin in urine samples. The overall recoveries of the different NSAIDs ranged between 50 and 80% with coefficients of variation of less than 15% (n = 5), and the limits of detection of the different NSAIDs were between 10 and 50 ng/mL (S/N = 3) in the full-scan mode. Extractive methylation has proved to be a versatile method for STA of various acidic drugs, poisons, and their metabolites in urine. It has also successfully been used for plasma analysis.

    The aim of this study was to develop an analytical procedure which allows the quantification of pharmaceuticals in water at the ng L(-1) level. Hence, it is reported research on the application of a rapid, inexpensive and simple continuous hollow fiber liquid-phase micro extraction (CHF-LPME) for the pre-concentration and determination of non-steroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen (IBP), naproxen (NAP), and ketoprofen (KEP), in wastewater. In this method, a 2.50 cm end sealed piece of a polypropylene hollow fiber was immersed into the organic solvent, octanol, for 30 s. After solvent impregnation with the pores of the fiber, the excess amounts of solvent were removed from inside the fiber, and 4.0 microL of octanol, as the acceptor phase, was injected into the fiber carefully. The fiber was settled using a microsyringe into a 10.0 mL glass test tube, and 20.00 mL of the aqueous solution (the donor phase), was circulated by a pump around it. After analyte extraction for an optimized period of time (20 min), 2 microL of the organic solvent was withdrawn into the microsyringe and injected into the GC-FID for further analysis. Finally, based on the optimized analytical conditions, the method was linear in the range of 2.5-500 ng L(-1). The limits of detection were 1-2 ng L(-1). Repeatability of this method on an intra-day scale was 3.4-10.2% (RSD%). NSAIDs have been detected in several municipal wastewater samples, and the concentration range was 9.0-19.0 ng L(-1).

  19. Efeito dos anti-inflamatórios não-esteroidais convencionais e seletivos para COX-2 sobre o reparo ósseo Effect of conventional and COX-2 selective non-steroidal antiinflammatory drugs on bone healing

    Full Text Available Na presente revisão de literatura foram relacionados trabalhos experimentais e clínicos dos últimos 15 anos referentes aos efeitos dos antiinflamatórios não-esteroidais (AINEs convencionais e seletivos para COX-2 sobre a formação óssea reparacional. A maioria dos trabalhos mostra que os AINEs convencionais podem atrasar o reparo de fratura de ossos longos e a fusão espinhal, em animais, e interferir negativamente com a taxa de fusão espinhal, em humanos. Apesar da importância comprovada da prostaglandina E2, sintetizada por osteoblastos sob estímulo da enzima ciclooxigenase-2 (COX-2, no controle da formação óssea, os resultados experimentais acerca dos prováveis efeitos inibitórios dos AINEs seletivos sobre o reparo ósseo além de raros são ainda controversos e não há comprovação de que eles interferem com a neoformação óssea reparacional em humanos.In the present literature review, experimental and clinical studies of the last 15 years concerning the effects of conventional and COX-2 selective non-steroidal anti-inflammatory drugs (NSAIDs on bone healing were reported. Most of the data pertaining to conventional NSAIDs have shown to cause delayed fracture healing and impairment of spinal fusion in animal studies, as well as a negative interference on spinal fusion rate in human beings. In spite of the established importance of prostaglandin E2, synthesized by osteoblasts under COX-2 stimulation, in controlling bone formation, the results regarding the potential inhibitory effects of selective NSAIDs on experimental bone healing are still controversial and there is no clinical data to confirm that they interfere negatively with repairing bone formation.

    Background Three types of non-steroidal anti-inflammatory drugs (NSAIDs) can be obtained both over the counter (OTC) and by prescription in the United States. OTC NSAID use is not recorded in prescription claims databases; this might lead to differential misclassification of NSAID exposure status in studies that use computerized pharmacy databases to study NSAID use. Objective To evaluate characteristics of OTC versus prescription NSAID users Methods This analysis is set within the Multi-Ethnic Study of Atherosclerosis (MESA) study; a prospective cohort study of 6,814 adults from 4 ethnic groups (European descent, Asian, African-American and Hispanic) with a mean age of 62 years. The cohort was restricted to those who initiated NSAID use (aspirin, ibuprofen or naproxen) during follow-up. We compared information about age, sex, ethnicity, body mass index, smoking, diabetes, medication use, education, income, health insurance status and exercisebetween groups. Results OTC NSAID use was prevalent at baseline (25% Aspirin, 9% Ibuprofen, 2% Naproxen). Compared to prescribed NSAID use, OTC NSAID use was lower for users of non-European descent for all classes: aspirin (p<0.0001), ibuprofen (p<0.0001) and naproxen (p=0.0094). For aspirin, differences were seen for male gender (Relative Risk (RR):0.92; 95%(Confidence interval) CI:0.86–0.98), use of lipid lowering drugs (RR:0.88; 95% CI: 0.80–0.96), low income (RR:0.89; 95%CI:0.81–0.97), and participants one standard deviation above average in intentional exercise (RR:1.03; 95%CI:1.01–1.05). Conclusions OTC NSAID use is prevalent in an older multi-ethnic population and OTC users differ from prescription NSAID users. Caution should be exercised when using prescribed NSAIDs as a proxy for NSAID use. PMID:21182156

    Rheumatoid arthritis (RA) is the most common form of chronic inflammatory arthritis characterized by pain, swelling and destruction of joints, with a resultant disability. Disease-modifying anti-rheumatic drugs (DMARDs) and biological drugs can interfere with the disease process. In this study, the effect of β-d-mannuronic acid (M2000) as a novel non-steroidal anti-inflammatory drug (NSAID) with immunosuppressive and anti-inflammatory effects together with antioxidant effects was evaluated on IL17, RORγt, IL4 and GATA3 gene expression in 12 RA patients. Previously, M2000 driven from sodium alginate (natural product; patented, DEU: 102016113018.4) has shown a notable efficacy in experimental models of multiple sclerosis, RA and nephrotic syndrome. This study was performed on 12 patients with RA who had an inadequate response to conventional treatments. During this trial, patients were permitted to continue the conventional therapy excluding NSAIDs. M2000 was administered orally at a dose of 500 mg twice daily for 12 weeks. The peripheral blood mononuclear cells (PBMCs) were collected before and after treatment to evaluate the expression levels of IL4, GATA3, IL17 and RORγt. The gene expression results showed that M2000 has a potent efficacy, so that it could not only significantly decrease IL17 and RORγt levels but also increase IL4 and GATA3 levels after 12 weeks of treatment. Moreover, the gene expression results were in accordance with the clinical and preclinical assessments. In conclusion, M2000 as a natural novel agent has therapeutic and immunosuppressive properties on RA patients (identifier: IRCT2014011213739N2).

    We have studied non-steroidal selective androgen receptor modulators (SARMs) to develop anti-osteoporosis drugs for males and females. Many SARMs have been studied for their anabolic effects on bone or muscle with reduced virilizing effects in male animals. However, the tissue selectivities of these agents in female animals have not been fully evaluated. We evaluated the novel SARM S-101479 from tetrahydroquinoline libraries in ovariectomized (OVX) rats. S-101479 preferentially bound to the androgen receptor with nanomolar affinity among nuclear receptors. It increased the bone mineral density (BMD) of femurs and diminished the effects on the uterus and clitoral gland in OVX rats. We then compared the effect of S-101479 on bone with those of commercial anti-osteoporosis drugs such as alendronate, raloxifene, and teriparatide. Furthermore, we evaluated the effects of combination treatments with these agents in OVX rats. After 16-week treatment, all agents significantly increased BMD, but the magnitude of bone mineral content (BMC) and/or bone size (projected bone area) were different. Alendronate, raloxifene, and teriparatide maintained BMC and bone size in this experimental dose. Only S-101479 increased BMC with bone size on single treatments. In combination treatment, S-101479 significantly increased BMC and bone size compared with single treatments of other agents. S-101479, like natural androgen, may have showed periosteal bone formation of the cortical area and indicated additive effects with commercial anti-osteoporosis drugs. These results indicate that S-101479 may be a useful anti-osteoporosis drug, particularly for patients with established severe osteoporosis.

    A novel method for online extraction, pH-gradient separation, and analysis of nine non-steroidal anti-inflammatory drugs (NSAIDs) was developed by coupling online eluent-switching technique to single anion-exchange chromatographic column/ion trap mass spectrometer (MS) and used for monitoring NSAIDs residues in pig serum. A neutral eluent and a pH-gradient eluent were used for extraction and separation of NSAIDs, respectively. Each of nine NSAIDs has an MS precursor ion of either [M−H]− or [M−Na]−. The extracted ion chromatogram for a specific product ion of each NSAID was used for its quantitative analysis. The dynamic linear ranges of calibration curves were all 0–200 ng mL−1 (R2 > 0.9950). The analysis accuracies estimated by spiking standard concentrations at 20, 100, and 200 ng mL−1 were 80.5–99.9%. The corresponding intra-day and inter-day precisions (RSD%) were 2.5–14.5% and 2.9–15.2%, respectively. The limit of detection/limit of quantitation of NSAIDs were 1.3/4.3, 0.5/1.6, 0.2/0.5, 2.5/8.2, 1.5/4.9, 0.6/2.1, 0.6/2.0, 0.5/1.7, and 0.6/2.1 ng mL−1 for carprofen, diclofenac, flunixin, ibuprofen, ketoprofen, meclofenamic acid sodium, mefenamic acid, niflumic acid, and tolfenamic acid, respectively. After 1 h injection of a dose containing 2 mg kg−1 weight pig of flunixin and tolfenamic acid to the pigs, a residue amount of 3480 ± 36 ng mL−1 and 431 ± 13 ng mL−1, respectively, was reached for the incurred pig serum specimens and both residues were reduced to about 20 ng mL−1 at the time of 24 h.

    Recent epidemiology and laboratory studies indicate that regular taking of aspirin and other non-steroidal anti-inflammatory drugs(NSAIDs) may reduce the risk of colorectal, esophageal, stomach and pancreatic cancers and other digestive cancers. Thus, aspirin and other NSAIDs may be an effective chemoprevention agent for digestive cancers. On the other hand, this protection effort may be benefitial to the course of the intervention, regression and prevention of cancer lesions. The possible mechanism of NSAIDs chemoprevention may be: (1)reducing the synthesis of prostaglandin(PG) and inhibiting cyclo-oxygenase(COX) activity; (2) inducing apoptosis in epithelial cells of the gastro-intestinal origin; (3)obstructing signaling transduction pathways of COX and PG. Now, chemoprevention of NSAIDs has become focus of research on cancer secondary prevention, as its protective effects of chemoprevention of digesrive cancer have been determined. NSAIDs, especially selective COX-2 inhibitor may be a novel useful chemoprevention agents for digestive cancer and their precursor lesions in future.%近年来,流行病学及实验室研究表明,长期使用阿斯匹林或其它非甾体类抗炎药(NSAIDs),可降低结、直肠癌、食管癌、胃癌、胰腺癌等消化道肿瘤的发病危险性,提示NSAIDs可能对消化道肿瘤具有一定的化学预防作用。同时,这一保护作用也很有可能在肿瘤的前期病变过程中发挥有益的阻断、逆转或预防作用。NSAIDs化学预防作用的可能机制:(1)抑制前列腺素(PG)合成和细胞环氧化酶(COX)活性;(2)诱导胃肠道来源的上皮细胞凋亡;(3)引起PG和COX调节通路的障碍。目前,NSAIDs的化学预防作用已经成为肿瘤二级预防领域的研究热点并已基本肯定了它在消化道肿瘤预防中的作用。NSAIDs,尤其是特异性环氧化酶-2抑制剂,有望成为肿瘤以及癌前病变新的化学预防的药物。

    Non-steroidal anti-inflammatory drugs are the group of pharmaceuticals that is most often found in the environment, whereas estrogenic hormones are considered to be potent endocrine disruptors. However, the fate and persistence of these compounds in the environment are still unclear. In this study we propose two approaches for determining these compounds in environmental water samples: GC-MS using time windows and operating in selected ion-monitoring mode (SIM) and, for the first time, gas chromatography with electron capture detection (GC-ECD). The identification criteria of both methods fulfilled the requirements of Directive 2002/657/EC. The use of time windows improved the sensitivity of GC-MS measurements. In GC-MS analysis the pharmaceuticals were determined as trimethylsilyl, in GC-ECD as pentafluoropropionyl derivatives. The influence of such parameters as the type of reagent, type of solvent, reaction time, reaction temperature and microwave irradiation in a household microwave oven on the efficacy of silylation was investigated. Derivatization using N,O-bis(trimethylsilyl)trifluoroacetamide (BSTFA) and 1% trimethylchlorosilane (TMCS) in pyridine (1:1, v/v) for 30 min in 60 Degree-Sign C was found to be optimal. Optimization of the solid phase extraction procedure (SPE) confirmed that the application of Oasis HLB cartridges, the acidification of loading samples to pH 2 and the use of methanol as eluent gave the best absolute recoveries (ARs) of the target compounds. The following ARs of all the compounds were achieved: 58.2-106.8% in influent wastewater, 77.8-103.4% in effluent wastewater and 81.2-101.9% in surface water samples. Validation of the SPE-GC-MS method enables 13 pharmaceuticals to be determined with MDLs between 3.3 and 343.6 ng/L, depending on the analytes and matrices. GC-ECD analysis enables the determination of 6 pharmaceuticals in surface water samples with MDLs between 0.7 and 5.4 ng/L. The proposed methods were successfully used for

    Accidental falls in older individuals are a major health and research topic. Increased reaction time and impaired postural balance have been determined as reliable predictors for those at risk of falling and are important functions of the central nervous system (CNS). An essential risk factor for falls is medication exposure. Amongst the medications related to accidental falls are the non-steroidal anti-inflammatory drugs (NSAIDs). About 1-10% of all users experience CNS side effects. These side effects, such as dizziness, headaches, drowsiness, mood alteration, and confusion, seem to be more common during treatment with indomethacin. Hence, it is possible that maintenance of (static) postural balance and swift reactions to stimuli are affected by exposure to NSAIDs, indomethacin in particular, consequently putting older individuals at a greater risk for accidental falls. The present study investigated the effect of a high indomethacin dose in healthy middle-aged individuals on two important predictors of falls: postural balance and reaction time. Twenty-two healthy middle-aged individuals (59.5 ± 4.7 years) participated in this double-blind, placebo-controlled, randomized crossover trial. Three measurements were conducted with a week interval each. A measurement consisted of postural balance as a single task and while concurrently performing a secondary cognitive task and reaction time tasks. For the first measurement indomethacin 75 mg (slow-release) or a visually identical placebo was randomly assigned. In total, five capsules were taken orally in the 2.5 days preceding assessment. The second measurement was without intervention, for the final one the first placebo group got indomethacin and vice versa. Repeated measures GLM revealed no significant differences between indomethacin, placebo, and baseline in any of the balance tasks. No differences in postural balance were found between the single and dual task conditions, or on the performance of the dual task

Las PGs participan en la regulación de diversas funciones celulares bajo condiciones fisiológicas y patológicas. La ciclooxigenasa (COX proporciona la conversión de AA a PGs en tres formas funcionalmente distintas: COX-1, COX-2 y COX-3. COX-2, se induce después de estimular una variedad de citoquinas inflamatorias, factores de crecimiento y lipopolisacáridos. Expresiones elevadas de COX-2 en periodontitis incrementan los niveles de PGs E2, considerados como los mayores mediadores de la destrucción tisular periodontal. Los antiinflamatorios no esteroides (AINES inhiben la elaboración de productos COX y pueden atenuar el avance de la pérdida ósea, convirtiéndose en una alternativa terapéutica para el manejo de la periodontitis.Periodontal tissue destruction occurs as a result of the interaction between dental plaque bacteria and the immunoinflamatory response induced by mediators like host enzymes, cytokines, and arachidonic acid metabolites such as prostaglandins (PGs.

The ciclooxigenase (COX enzyme providing the conversion of AA to PGs exists in two functionally distinct COX isoforms: COX-1 and COX-2. COX-2. The COX-2, is induced after stimulation by a variety of inflammatory cytokines, growth factors, and lipopolysaccarides.

    Non-steroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed by veterinary surgeons for the treatment of canine osteoarthritis, and affected dogs may receive these drugs for long periods of time. Whilst short term administration of NSAIDs to dogs is linked to adverse events such as gastrointestinal haemorrhage and renal injury, reports of adverse events associated with their long-term administration are limited in the veterinary literature. This study aimed to investigate the attitudes towards the long term use of NSAIDs for canine osteoarthritis held by three groups who manage osteoarthritic dogs in the United Kingdom: dog owners, veterinary surgeons and veterinary nurses. A qualitative methodology was adopted, using semi-structured interviews and focus groups. Thematic analysis of these data identified three themes: awareness of potential risks; recognition of adverse events; and influence of risk perception on the use of NSAIDs. Awareness of, and concern about, the risk of adverse events associated with NSAID administration to dogs with osteoarthritis was high in all groups, with veterinary surgeons being one of a variety of information sources used by owners to acquire this knowledge. Veterinary surgeons described difficulty in recognising, managing and avoiding adverse events associated with NSAIDs. When adverse events occurred, a wide range of management approaches were adopted ranging from a brief drug respite to permanent cessation of administration of any NSAIDs to that dog. Commonly employed approaches to minimise risk included dose reduction and screening blood tests. This study describes a high level of concern about the risks associated with long term NSAID administration to dogs with osteoarthritis and highlights a diverse range of strategies employed to minimise these risks. The evidence base for these strategies is poor, and this may present a risk to animal welfare if the affected dogs are not receiving adequate analgesia. In order to

    AF1Q, a mixed lineage leukemia gene fusion partner, is identified as a poor prognostic biomarker for pediatric acute myeloid leukemia (AML), adult AML with normal cytogenetic and adult myelodysplastic syndrome. AF1Q is highly regulated during hematopoietic progenitor differentiation and development but its regulatory mechanism has not been defined clearly. In the present study, we used pharmacological and genetic approaches to influence chaperone-mediated autophagy (CMA) and explored the degradation mechanism of AF1Q. Pharmacological inhibitors of lysosomal degradation, such as chloroquine, increased AF1Q levels, whereas activators of CMA, including 6-aminonicotinamide and nutrient starvation, decreased AF1Q levels. AF1Q interacts with HSPA8 and LAMP-2A, which are core components of the CMA machinery. Knockdown of HSPA8 or LAMP-2A increased AF1Q protein levels, whereas overexpression showed the opposite effect. Using an amino acid deletion AF1Q mutation plasmid, we identified that AF1Q had a KFERQ-like motif which was recognized by HSPA8 for CMA-dependent proteolysis. In conclusion, we demonstrate for the first time that AF1Q can be degraded in lysosomes by CMA. - Highlights: • Chaperone-mediated autophagy (CMA) is involved in the degradation of AF1Q. • Macroautophagy does not contribute to the AF1Q degradation. • AF1Q has a KFERQ-like motif that is recognized by CMA core components.

  17. Digitalisering af undervisningen i almen patologi

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Patologi er læren om sygdommes manifestationer i væv og celler, herunder sygdommes årsager og mekanismer, og er en central del af undervisningen på en lang række studier om menneskers og dyrs sygdomme. Imod slutningen af 00’erne kom de første præparatscannere til Danmark, og for faget almen patologi på Københavns Universitet blev dette udnyttet til at forbedre og modernisere undervisningen. Faget baserer nu sin undervisning på digitalisering og anvendelse af digitale medier, og både undervisning og eksamen i vævs- og celleforandringer foregår nu med digitale hjælpemidler. I løbet af de sidste fem år er alle vævspræparater digitaliserede, og sideløbende hermed er den elektroniske platform for faget blevet udbygget. Fagets egne forelæsninger videooptages og streames, forelæsninger udført af internationalt anerkendte undervisere på udenlandske universiteter transmitteres live, og en patologi-blog øger studerendes adgang til underviserne. Til selvstudium udvikles multiple choice-tests baseret på mikroskopipræparater samt korte filmklip, der gennemgår mikroskopiforandringerne. Digitale spørgeskemaer har vist, at disse tiltag har forbedret undervisningen og øget studentertilfredsheden ganske betydeligt. Denne oversigtsartikel vil præsentere de digitale tiltag og deres betydning for undervisningen i patologi på Københavns Universitet.

  17. Enhancement of antinociception by coadminstration of minocycline and a non-steroidal anti-inflammatory drug indomethacin in naïve mice and murine models of LPS-induced thermal hyperalgesia and monoarthritis

    Directory of Open Access Journals (Sweden)

    Masocha Willias

    2010-12-01

    Full Text Available Abstract Background Minocycline and a non-steroidal anti-inflammatory drug (NSAID indomethacin, have anti-inflammatory activities and are both used in the management of rheumatoid arthritis. However, there are no reports on whether coadministration of these drugs could potentiate each other's activities in alleviating pain and weight bearing deficits during arthritis. Methods LPS was injected to BALB/c mice intraperitoneally (i.p. to induce thermal hyperalgesia. The hot plate test was used to study thermal nociception in naïve BALB/c and C57BL/6 mice and BALB/c mice with LPS-induced thermal hyperalgesia and to evaluate antinociceptive effects of drugs administered i.p. Monoarthritis was induced by injection of LPS intra-articularly into the right hind (RH limb ankle joint of C57BL/6 mice. Weight bearing changes and the effect of i.p. drug administration were analyzed in freely moving mice using the video-based CatWalk gait analysis system. Results In naïve mice indomethacin (5 to 50 mg/kg had no significant activity, minocycline (25 to 100 mg/kg produced hyperalgesia to thermal nociception, however, coadministration of minocycline 50 mg/kg with indomethacin 5 or 10 mg/kg produced significant antinociceptive effects in the hot plate test. A selective inhibitor of COX-1, FR122047 (10 mg/kg and a selective COX-2 inhibitor, CAY10404 (10 mg/kg had no significant antinociceptive activities to thermal nociception in naïve mice, however, coadministration of minocycline, with CAY10404 but not FR122047 produced significant antinociceptive effects. In mice with LPS-induced hyperalgesia vehicle, indomethacin (10 mg/kg or minocycline (50 mg/kg did not produce significant changes, however, coadministration of minocycline plus indomethacin resulted in antinociceptive activity. LPS-induced RH limb monoarthritis resulted in weight bearing (RH/left hind (LH limb paw pressure ratios and RH/LH print area ratios deficits. Treatment with indomethacin (1 mg/kg or

    地诺前列酮是牙槽骨吸收最有力的刺激因子,既可刺激破骨细胞引起破骨性骨吸收,破坏牙周组织;还可提高缓激肽和组胺水平,引起疼痛的感觉。地诺前列酮与血栓素A2间失衡,会影响血管生成和组织愈合。非甾体类抗炎药(NSAID)可抑制人体内的环加氧酶活性,减少地诺前列酮的生成,从而降低牙周炎症,缓解疼痛;可引起内皮细胞通透性降低,影响急性期多种细胞的迁移;可抑制透明质酸的形成,从而影响细胞增殖。布洛芬缓释凝胶和米诺环素-布洛芬缓释凝胶均能有效地改善慢性牙周炎的临床症状,控制牙周炎症,减少组织破坏。NSAID用于牙周组织再生术治疗,对骨移植后的骨再生有明显的促进作用。NSAID对于牙周炎的治疗既有优势,也有不可忽视的缺点。NSAID会抑制血栓素A2的生成,减少血小板的聚集,从而增加患者血肿和持续出血的风险。牙周手术与此类药物怎样结合应用才能收到最佳效果,NSAID能否在牙周再生手术中起到促进作用仍需进一步探讨。%Dinoprostone is a powerful stimulating factor for alveolar bone resorption. It can destroy periodontal tissues by activating osteoclasts and cause pain by increasing the level of bradykinin and histamine. The imbalance between Dinoprostone and thromboxane A2 may influence angiogenesis and tissue healing. Non-steroidal anti-inflammatory drugs(NSAID) can reduce the production of Dinoprostone by inhibiting the clyco-oxygenase activity, thus decreasing the periodontal inflammation and relieving pain. It can also reduce the permeability of endothelial cells and influence cell migration during the acute inflammation period. It can inhibit the formation of hyaluronic acid and affect cell proliferation. Ibuprofen gel and minocycline-ibuprofen gel can improve the clinical symptoms of chronic periodontitis effectively and reduce tissue destruction

    2015-05-01

    Full Text Available In 2012, an Indian parliamentary committee reported that manufacturing licenses for large numbers of fixed dose combination (FDC drugs had been issued by state authorities without prior approval of the Central Drugs Standard Control Organization (CDSCO in violation of rules, and considered that some ambiguity until 1 May 2002 about states' powers might have contributed. To our knowledge, no systematic enquiry has been undertaken to determine if evidence existed to support these findings. We investigated CDSCO approvals for and availability of oral FDC drugs in four therapeutic areas: analgesia (non-steroidal anti-inflammatory drugs [NSAIDs], diabetes (metformin, depression/anxiety (anti-depressants/benzodiazepines, and psychosis (anti-psychotics.This was an ecologic study with a time-trend analysis of FDC sales volumes (2007-2012 and a cross-sectional examination of 2011-2012 data to establish the numbers of formulations on the market with and without a record of CDSCO approval ("approved" and "unapproved", their branded products, and sales volumes. Data from the CDSCO on approved FDC formulations were compared with sales data from PharmaTrac, a database of national drug sales. We determined the proportions of FDC sales volumes (2011-2012 arising from centrally approved and unapproved formulations and from formulations including drugs banned/restricted internationally. We also determined the proportions of centrally approved and unapproved formulations marketed before and after 1 May 2002, when amendments were made to the drug rules. FDC approvals in India, the United Kingdom (UK, and United States of America (US were compared. For NSAID FDCs, 124 formulations were marketed, of which 34 (27% were centrally approved and 90 (73% were unapproved; metformin: 25 formulations, 20 (80% approved, five (20% unapproved; anti-depressants/benzodiazepines: 16 formulations, three (19% approved, 13 (81% unapproved; anti-psychotics: ten formulations, three (30

    Willis, Peter; White, Victor; Grunthaner, Frank; Ikeda, Mike; Mathies, Richard A.

    2009-01-01

    Microfluidic pumps and valves based on pneumatically actuated diaphragms made of Teflon AF polymers are being developed for incorporation into laboratory-on-a-chip devices that must perform well over temperature ranges wider than those of prior diaphragm-based microfluidic pumps and valves. Other potential applications include implanted biomedical microfluidic devices, wherein the biocompatability of Teflon AF polymers would be highly advantageous. These pumps and valves have been demonstrated to function stably after cycling through temperatures from -125 to 120 C. These pumps and valves are intended to be successors to similar prior pumps and valves containing diaphragms made of polydimethylsiloxane (PDMS) [commonly known as silicone rubber]. The PDMS-containing valves ae designed to function stably only within the temperature range from 5 to 80 C. Undesirably, PDMS membranes are somwehat porous and retain water. PDMS is especially unsuitable for use at temperatures below 0 C because the formation of ice crystals increases porosity and introduces microshear.

Undersøgelsen er motiveret af tidligere observationsstudier (Johansen, 2005) 1, der blandt andet har vist, at småbørn i høj grad er tv......-lyttere. For eksempel har det vist sig, at et lille barn sjældent sidder stille foran tv ret længe ad gangen, men derimod forholder sig til tv såvel som til en række andre fænomener (legetøj, andre personer osv.) på samme tid. Det har vist sig, at auditive fænomener spiller en vigtig rolle i denne sammenhæng: Selv når...... barnet kigger væk eller går ind i et andet rum, er tv’ets lyd en kontinuerlig anknytning til tv’et, og lyde kan for eksempel fungere som en kulisse, der integreres i barnets leg, ligesom lyde kan hidkalde – og i perioder bidrage til at fastholde – barnets visuelle opmærksomhed....
