Abstract
Indomethacin (INDO) is an NSAID with remarkable efficacy and widespread utilization for alleviating pain. Nevertheless, renal function impairment is an adverse reaction linked to INDO usage. Nifuroxazide (NFX), an oral nitrofuran antibiotic, is frequently employed as an intestinal anti-infective agent. Our study aimed to investigate the renoprotective effects of NFX against INDO-induced nephrotoxicity and explore the protection mechanisms. Four groups of rats were allocated to (I) the normal control, (II) the NFX-treated (50 mg/kg), (III) INDO control (20 mg/kg), and (IV) NFX + INDO. NFX attenuates renal impairment in INDO-induced renal injury, proved by decreasing serum levels of urea, creatinine, uric acid, and NGAL while the albumin was elevated. NFX mitigates renal oxidative stress by decreasing MDA levels and restoring the antioxidants' GSH and SOD levels mediated by upregulating Nrf2, HO-1, and cytoglobin pathways. NFX mitigated renal inflammation and effectively decreased MPO, IL-1β, and TNF-α levels in the rat's kidney mediated by significant downregulation of NADPH-oxidase and NF-κB expression and suppression of JAK-1 and STAT3 phosphorylation. NFX mitigates renal apoptosis by decreasing the expression of cleaved caspase-3 expression. In conclusion, NFX treatment prevents INDO nephrotoxicity by regulating Nrf2/HO-1, cytoglobin, NADPH-oxidase, NF-κB, and JAK-1/STAT3 signals.

Abstract
PURPOSE OF REVIEW Strong epidemiological and pathologic evidence associates NSAIDs with kidney disease, both acute and chronic. Hence, the usage of NSAIDs has decreased in patients with, or at risk for, chronic kidney disease (CKD). Coupled with this has been a rise in use of opioids and other non-NSAID alternatives, which do come with significant, and underrecognized, risk of nonrenal adverse events. We review the literature to understand if this shift is appropriate or deleterious. RECENT FINDINGS NSAIDs do have a low but tangible risk in causing acute kidney injury, electrolyte imbalances, and increasing blood pressure. However, their role in causing progressive kidney disease is due to long-term usage in high cumulative dosages, and the use of NSAIDs in combination with other agents. Alternatives such as opioids, tramadol, gabapentin and baclofen have weak evidence to support their use and strong evidence to show their harm in patients with CKD. SUMMARY Tradeoffs are inherent in using active pharmaceuticals, and NSAIDs are no exception. Balancing potential benefits with possible adverse effects around pain management should be a part of every conversation for patients with kidney disease.

Abstract
A transdermal patch formulation of a non-steroidal anti-inflammatory drug (NSAID) used by a 44-year-old man resulted in acute interstitial nephritis and acute tubular injury. This patient also had a history of mild kidney dysfunction and osteoporosis. The NSAID patch had been prescribed after a traffic accident. He was also receiving a vitamin D analog and taking over-the-counter calcium supplements. Two months later, renal dysfunction and hypercalcemia were discovered. A renal biopsy showed acute interstitial nephritis and acute tubular injury. Once these agents were withdrawn, the renal function recovered. This is the first reported occurrence of biopsy-proven acute interstitial nephritis attributable to NSAID patch usage.

Abstract
BACKGROUND AND OBJECTIVES Nonsteroidal anti-inflammatory drugs (NSAIDs) have been associated with AKI. Their association with nephrotic syndrome has not been systematically studied. This study aimed to assess the risk of nephrotic syndrome associated with NSAID use. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS A matched case-control study was performed in the UK primary care database. Cases were patients with a first diagnosis of nephrotic syndrome and controls were those without nephrotic syndrome. NSAID exposure (grouped either based on cyclooxygenase enzyme selectivity and chemical groups) was classified as either current (use at the nephrotic syndrome diagnosis date and corresponding date in the control group), recent, or past use. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were calculated using unconditional logistic regression analysis. RESULTS We included 2620 cases and 10,454 controls. Compared with non-use, current use of 15-28 days and >28 days of conventional NSAIDs was associated with a higher relative risk of nephrotic syndrome: adjusted OR, 1.34; 95% CI, 1.06 to 1.70, and OR, 1.42; 95% CI, 0.79 to 2.55, respectively. Also, recent use (discontinuation 1-2 months before nephrotic syndrome diagnosis date; OR, 1.55; 95% CI, 1.11 to 2.15) and past use (discontinuation 2 months-2 years; OR, 1.24; 95% CI, 1.07 to 1.43), but not current use of <15 days (OR, 0.78; 95% CI, 0.46 to 1.31) nor past use (discontinuation >2 years; OR, 0.96; 95% CI, 0.85 to 1.09) were associated with a higher relative risk of nephrotic syndrome as well as past use of selective COX-2 inhibitors (discontinuation 2-24 months; OR, 1.24; 95% CI, 0.98 to 1.58). Categorization based on chemical groups showed that acetic acid and propionic acid derivatives were associated with a higher risk of nephrotic syndrome. CONCLUSIONS The use of conventional NSAIDs was associated with a higher risk of nephrotic syndrome starting from at least 2 weeks of exposure, as well as for recent and past exposure up to 2 years before the diagnosis of nephrotic syndrome. This higher risk appeared mainly attributable to acetic acid and propionic acid derivatives.

Abstract
INTRODUCTION The kidney is a major target for toxicity elicited by pharmaceuticals and environmental pollutants. Standard testing which often does not investigate underlying mechanisms has proven not to be an adequate hazard assessment approach. As such, there is an opportunity for the application of computational approaches that utilize multiscale data based on the Adverse Outcome Pathway (AOP) paradigm, coupled with an understanding of the chemistry underpinning the molecular initiating event (MIE) to provide a deep understanding of how structural fragments of molecules relate to specific mechanisms of nephrotoxicity. Aims covered: The aim of this investigation was to review the current scientific landscape related to computational methods, including mechanistic data, AOPs, publicly available knowledge bases and current in silico models, for the assessment of pharmaceuticals and other chemicals with regard to their potential to elicit nephrotoxicity. A list of over 250 nephrotoxicants enriched with, where possible, mechanistic and AOP-derived understanding was compiled. Expert opinion: Whilst little mechanistic evidence has been translated into AOPs, this review identified a number of data sources of in vitro, in vivo, and human data that may assist in the development of in silico models which in turn may shed light on the interrelationships between nephrotoxicity mechanisms.

Abstract
Of 1015 men over the age of 60, 125 (12.3%) were found to have dipstick haematuria on a single test. Analysis of smoking history revealed a 1.6 fold increased incidence of dipstick haematuria in current smokers as compared with ex-smokers and non-smokers. The relationship with bladder cancer and smoking is discussed. Several commonly used drugs, including nonsteroidal anti-inflammatory preparations, have been implicated as a cause of urinary tract bleeding. In this study of 1015 men over the age of 60, no association was found between the presence of dipstick haematuria and the intake of aspirin, other nonsteroidal anti-inflammatory drugs or warfarin.

Abstract
Mitigation of thermal stress and adverse indoor climatic conditions is important to older low-income populations whose age, health, and economic circumstances make them vulnerable to indoor environmental conditions. This research examines whether energy retrofits in affordable housing for older adults can also improve indoor climatic (i.e., temperature, humidity, air infiltration) conditions and whether such improvements correspond with improved health and comfort of residents. An apartment complex for low-income older adults in Phoenix was the study site. In 2010, renovations were undertaken to make it more energy efficient and to replace interior cabinetry, flooring, and paint with materials that had low or no volatile organic compounds (VOCs). Fifty-seven residents from 53 apartment units participated in both baseline (pre-renovation) and 1 year post-renovation data collection trials. Environmental measures included temperature, relative humidity, and air infiltration. Health measures included general health, emotional distress, and sleep. Four questions addressed residents' perceptions of temperature quality. Results demonstrated a 19% reduction in energy consumption following the retrofit. In addition, fixed effects statistical models of the panel data showed significant stabilization of unit temperature from pre-retrofit to 1 year post-retrofit. Reductions in an apartment's temperature extremes of 27.2°C (81°F) and above also corresponded with improvement in occupant's reported health over the same time period, although not with occupant's perceptions of thermal comfort.

Abstract
Acute renal failure is an important cause of morbidity in critically ill patients. Acute renal failure results from pre renal and postrenal causes and, most importantly, acute tubular necrosis (ATN). Although it is known that renal toxins and renal ischemia are the most common causes of ATN in hospitalized patients, the exact pathogenesis of this entity is still not fully understood. Patients in the intensive care unit are at high risk for ATN because of hemodynamic instability, the administration of neph rotoxic antibiotics or chemotherapeutic agents, and ex posure to radiographic contrast agents. The acquired immunodeficiency syndrome is also associated with an increased risk of renal failure development, either from complications of the disease itself or from its treatment. Many consequences of acute renal failure such as vol ume overload, acidosis, hyperkalemia, and serositis can be managed adequately with peritoneal dialysis, hemo dialysis, or a newer technique, continuous arteriove nous hemofiltration. Despite improvements in treat ment, however, the mortality of ATN remains high. In this review, we recommend measures to prevent ATN in certain clinical situations that commonly occur among critically ill patients. We also review therapeutic options for treating patients in whom acute renal failure devel ops and discuss newer developments that may begin to reduce the excessive morbidity associated with ATN.

Abstract
OBJECTIVE: The purpose of this article is to review the pathophysiology of the denervated heart and the factors that need to be considered before recommending the use of over-the-counter (OTC) medications in the cardiac transplant recipient. DATA SOURCES: Pharmacology and therapeutic textbooks, English-language journal articles, and physiology textbooks published between 1969 and 1991. DATA EXTRACTION: Case reports, controlled case studies, and textbook chapters evaluating drug interactions with immunosuppressive agents were reviewed. The effects of various OTC medications on the denervated heart were examined and relevant material was extrapolated. DATA ANALYSIS: The number of cases or studies in which a particular effect or interaction occurred was reported. Those findings that were less well documented were either identified as such or were not included in the review. DATA SYNTHESIS: Common pharmacokinetic and pharmacodynamic interactions with the primary immunosuppressive agents (e.g., cyclosporine, azathioprine, prednisone) are reviewed. The physiology and altered responses of the denervated heart to various medications are also explained. Using this information, recommendations are given for the use and monitoring of OTC analgesics, antacids, laxatives, sleep aids, stimulants, and other medications that may be used in the cardiac transplant recipient. CONCLUSIONS: Many OTC medications can be used safely in the cardiac transplant recipient. In each situation, risk/benefit assessments must always be made and therapy should be monitored closely. Most important, patients should always notify the transplant team before adding an OTC product to their immunosuppressive regimen.

Abstract
OBJECTIVE To quantify plasma concentrations and determine adverse ocular, renal, or hepatic effects associated with repeated topical ophthalmic application of 0.1% diclofenac to healthy cats. ANIMALS 8 healthy sexually intact male cats. PROCEDURES A randomized, placebo-controlled crossover study was conducted. A topical formulation of 0.1% diclofenac was administered 4 times/d for 7 days to 4 cats, and artificial tear (control) solution was administered to the other 4 cats. After a 12-day washout period, cats received the other treatment. Ophthalmic examinations were performed daily. Plasma samples were obtained on days 1 and 7 for pharmacokinetic analysis. A CBC, serum biochemical analysis, urinalysis, determination of urine protein-to-creatinine ratio, and determination of glomerular filtration rate were performed before the start of the study and after each 7-day treatment period. RESULTS Mild conjunctival hyperemia was the only adverse ocular effect detected. Maximal drug concentration and area under the curve were significantly higher on day 7 than on day 1. Diclofenac-treated cats had a significantly lower glomerular filtration rate than did control-treated cats after the second but not after the first treatment period, presumably associated with iatrogenic hypovolemia. CONCLUSIONS AND CLINICAL RELEVANCE Topical ophthalmic administration of 0.1% diclofenac was well tolerated in healthy cats, with only mild signs of ocular irritation. Detectable systemic concentrations of diclofenac were achieved with accumulation over 7 days. Systemic absorption of diclofenac may be associated with reduced glomerular filtration rate, particularly in volume-contracted animals. Topical ophthalmic 0.1% diclofenac should be used with caution in volume-contracted or systemically ill cats.

Abstract
BACKGROUND Better evidence regarding drug safety in the pediatric population might be generated from existing data sources such as spontaneous reporting systems and electronic healthcare records. The Global Research in Paediatrics (GRiP)-Network of Excellence aims to develop pediatric-specific methods that can be applied to these data sources. A reference set of positive and negative drug-event associations is required. OBJECTIVE The aim of this study was to develop a pediatric-specific reference set of positive and negative drug-event associations. METHODS Considering user patterns and expert opinion, 16 drugs that are used in individuals aged 0-18 years were selected and evaluated against 16 events, regarded as important safety outcomes. A cross-table of unique drug-event pairs was created. Each pair was classified as potential positive or negative control based on information from the drug's Summary of Product Characteristics and Micromedex. If both information sources consistently listed the event as an adverse event, the combination was reviewed as potential positive control. If both did not, the combination was evaluated as potential negative control. Further evaluation was based on published literature. RESULTS Selected drugs include ibuprofen, flucloxacillin, domperidone, methylphenidate, montelukast, quinine, and cyproterone/ethinylestradiol. Selected events include bullous eruption, aplastic anemia, ventricular arrhythmia, sudden death, acute kidney injury, psychosis, and seizure. Altogether, 256 unique combinations were reviewed, yielding 37 positive (17 with evidence from the pediatric population and 20 with evidence from adults only) and 90 negative control pairs, with the remainder being unclassifiable. CONCLUSION We propose a drug-event reference set that can be used to compare different signal detection methods in the pediatric population.

Abstract
Supplemental Digital Content is available in the text. Background— Cardiovascular side effects associated with cyclooxygenase-2 inhibitor drugs dominate clinical concern. Cyclooxygenase-2 is expressed in the renal medulla where inhibition causes fluid retention and increased blood pressure. However, the mechanisms linking cyclooxygenase-2 inhibition and cardiovascular events are unknown and no biomarkers have been identified. Methods and Results— Transcriptome analysis of wild-type and cyclooxygenase-2−/− mouse tissues revealed 1 gene altered in the heart and aorta, but >1000 genes altered in the renal medulla, including those regulating the endogenous nitric oxide synthase inhibitors asymmetrical dimethylarginine (ADMA) and monomethyl-l-arginine. Cyclo-oxygenase-2−/− mice had increased plasma levels of ADMA and monomethyl-l-arginine and reduced endothelial nitric oxide responses. These genes and methylarginines were not similarly altered in mice lacking prostacyclin receptors. Wild-type mice or human volunteers taking cyclooxygenase-2 inhibitors also showed increased plasma ADMA. Endothelial nitric oxide is cardio-protective, reducing thrombosis and atherosclerosis. Consequently, increased ADMA is associated with cardiovascular disease. Thus, our study identifies ADMA as a biomarker and mechanistic bridge between renal cyclooxygenase-2 inhibition and systemic vascular dysfunction with nonsteroidal anti-inflammatory drug usage. Conclusions— We identify the endogenous endothelial nitric oxide synthase inhibitor ADMA as a biomarker and mechanistic bridge between renal cyclooxygenase-2 inhibition and systemic vascular dysfunction.

Abstract
BACKGROUND Because oral nonsteroidal anti-inflammatory drugs (NSAIDs) have adverse effects on kidney function, patients with kidney diseases are administered these drugs as transdermal patches. Little is known about the effects of NSAID patches on renal function. We therefore assessed the effects of topical loxoprofen sodium on kidney function in type 2 diabetic patients with overt nephropathy. METHODS Twenty patients with type 2 diabetes and overt proteinuria and with knee and/or low back pain were treated with skin patches containing 100 mg loxoprofen on the knee or back for 24 h per day for 5 consecutive days. The degree of pain was assessed using a visual analogue scale (VAS). Blood and 24-h urine samples were obtained at baseline and at the end of the study. Glomerular filtration rate (GFR) was estimated from serum creatinine and cystatin C concentrations. RESULTS The 20 patients consisted of 11 males and 9 females, of mean age 61.6 ± 13.9 years. Loxoprofen-containing patches significantly reduced VAS pain without affecting blood pressure, GFR or urinary prostaglandin E2 concentration. Serum concentrations of loxoprofen and its active trans-OH metabolite did not correlate with GFR. CONCLUSIONS Loxoprofen-containing patches do not affect renal function in type 2 diabetic patients with overt nephropathy over a short-term period. Long-term studies are needed to clarify the safety of loxoprofen-containing patches in patients with chronic kidney diseases.

Abstract
At present, intramuscular application of opioids given on request is the most widespread form of postoperative analgesia. This method is widely recognized as often being inadequate, however. As advanced techniques of pain management, such as patient-controlled analgesia, are not generally available, the question arises as to whether non-opioid analgesics should routinely be used in order to improve this situation. A review of the literature indicates that apart from when used following abdominal surgery, in particular, operations on the biliary tract, non-steroidal anti-inflammatory drugs (NSAIDS) offer effective postoperative pain control. Following minor surgery, the quality of analgesia can be better than that achieved with the weak opioids. The discrepancy between biliary tract operations and all other forms of surgery raises the question whether in the former case pain may have been partly due to spasms of visceral smooth muscle and hence be less readily amenable to the action of NSAIDS. A potential problem with the perioperative use of NSAIDS is that they inhibit platelet aggregation. Apart from tonsillectomy, there are no reports of increased intra- or postoperative bleeding when these drugs have been used for minor surgery, and only isolated reports following major operations. Despite these results, it must be borne in mind that most studies have been carried out on patients of ASA groups I and II and that conclusions drawn from the literature are not necessarily representative for the elderly and for patients with organ failure. Alternative substances have received relatively little attention. Of these, the pyrazolone derivative, metamizol, may well prove to be of value for patients in whom the use of NSAIDS is contraindicated or relatively ineffective such as after biliary tract surgery.

Abstract
BACKGROUND Postoperative acute kidney injury (AKI) following bariatric surgery has not been well studied. The aim of this study is to identify factors associated with risk of AKI. METHODS The medical records of adult patients who underwent bariatric surgery between March 1, 2005 and March 31, 2011 at the Mayo Clinic were reviewed to identify patients who experienced AKI, defined as postoperative increase in serum creatinine (sCr) by 0.3 mg/dL within 72 h. For each AKI case, two controls were matched for surgical approach (laparotomy vs. laparoscopic). A chart review was conducted and conditional logistic regression analyses were performed to identify risk factors for AKI. RESULTS There were 1,227 patients who underwent bariatric surgery, and of these, 71 developed AKI (5.8 %). The median sCr increase was 0.4 (interquartile range 0.3-0.6) mg/dL. Independent patient factors associated with increased risk included higher body mass index [odds ratio (OR) 1.24, 95 % CI 1.06-1.46 per 5 unit increase, P = 0.01] and medically treated diabetes mellitus (OR 2.77, 1.36-5.65, P = 0.01). Patients experiencing AKI had higher rates of blood transfusions (P < 0.01), postsurgical complications (P < 0.01), and longer hospital stays (P < 0.01). Another 30 patients developed kidney injury after 72 postoperative hours, usually in the setting of dehydration. CONCLUSIONS Kidney injury following bariatric surgery is not uncommon and is associated with higher body mass index and diabetes. Further, there should be a high risk of suspicion for kidney injury in postoperative patients developing volume depletion.

Abstract
Acute kidney injury (AKI) is a well-recognized complication of minimal change nephrotic syndrome (MCNS). Previous reports support the concept that AKI associated with MCNS is reversible; however, information regarding the hemodynamic basis of AKI in MCNS is insufficient. We herein describe a case of AKI in a man with MCNS. In this case, monitoring the longitudinal changes in renal perfusion using serial Tc-99m-MAG3 renal scanning was beneficial for evaluating the pathophysiological background associated with the development of AKI. The potential impact of serial renal scanning in MCNS patients with AKI will also be discussed.

Abstract
AIM To evaluate the adverse effects of flunixin, ketoprofen and phenylbutazone when administered I/V to clinically normal miniature donkeys. METHODS Twenty clinically normal adult (2.0-2.5 years old) male miniature donkeys weighing 113-136 kg and 0.81- 0.86 m tall were randomly assigned to one of four groups, and administered either saline (n=5), 1.0 mg/kg flunixin (n=5), 2.2 mg/kg ketoprofen (n=5), or 4.4 mg/kg phenylbutazone (n=5) I/V at 0800 hours on Day 1, then every 12 h, for 12 days. The animals were observed every 8 h, and examined physically daily. Blood, faeces and urine samples were collected daily from all donkeys, for haematological indices and enzyme activities, occult blood, and urinalysis, respectively. Immediately after euthanasia, complete post-mortem examinations were performed on all donkeys, and gross lesions recorded. Histopathology was conducted on a wide range of tissues. RESULTS Clinically, mild anorexia and diarrhoea were observed during the study only in donkeys treated with phenylbutazone. There was an effect of treatment with the non-steroidal anti-infl ammatory drugs (NSAID) on red blood cell (RBC) counts, packed cell volume (PCV) and enzyme activities, but not on urine. Lesions were observed in the glandular mucosa of the stomach of all donkeys treated with NSAID, including ulceration in most. Also, in donkeys treated with NSAID, hyperaemia, erosion and ulceration of the gastrointestinal tract, and congestion of the liver, kidney and spleen, were observed. Microscopically, hepatic and renal lesions comprised biliary hyperplasia and interstitial nephritis, respectively. CONCLUSIONS AND CLINICAL RELEVANCE The gastrointestinal, hepatic and renal lesions observed in the donkeys treated with NSAID demonstrated the toxic potential of NSAID, which was greatest for animals treated with phenylbutazone, less for flunixin, and least for ketoprofen. When use of these compounds is contemplated in clinical cases, the risk of adverse effects and the comparative toxic potential should be considered, together with the efficacy of the compound for the condition being treated.

Abstract
INTRODUCTION Flavocoxid is a novel flavonoid-based "dual inhibitor" of the 5-lipoxygenase (5-LOX) enzyme and the cyclooxygenase (COX) enzymes. This study was designed to compare the effectiveness and safety of flavocoxid to naproxen in subjects with moderate to severe osteoarthritis (OA) of the knee. METHODS In this randomized, multicenter, double-blind study, 220 subjects were assigned to receive either flavocoxid (500 mg twice daily) or naproxen (500 mg twice daily) for 12 weeks. The trial was structured to show noninferiority of flavocoxid to naproxen. Primary outcome measures included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and subscales and a timed walk. RESULTS More than 90% of the subjects in both groups noted significant reduction in the signs and symptoms of knee OA. There were no statistically significant differences in efficacy between the flavocoxid and naproxen groups when the entire intent-to-treat population was analyzed. The flavocoxid group had significantly fewer upper gastrointestinal (UGI) and renal (edema) adverse events (AEs) as well as a strong trend toward fewer respiratory AEs. CONCLUSION Flavocoxid, a first-in-class flavonoid-based therapeutic that inhibits COX-1 and COX-2 as well as 5-LOX, was as effective as naproxen in managing the signs and symptoms of OA of the knee. Flavocoxid demonstrated better UGI, renal (edema), and respiratory safety profiles than naproxen.

Abstract
BACKGROUND When monitoring postoperative urine output there is no guidance specific to obstetrics. Factors such as peri-operative oxytocin infusions add further complexity. Our aim was to determine a normal range for urine output after elective caesarean section under neuraxial anaesthesia. METHODS Sixty women were recruited and for 24h from the time of urethral catheterisation, we recorded urine output and fluid input. We also measured intra-operative blood loss, use of prophylactic oxytocin infusion and markers of renal function. Data were compared with Mann-Whitney U-tests or paired t tests. RESULTS Oxytocin infusions were used in 45 women (75%). Median (95% CI) urine output in the first 6h was 0.8 (0.4-1.9) mL kg(-1)h(-1) in women receiving oxytocin compared to 1.4 (0.7-2.2)mL kg(-1)h(-1) in those who did not (P=0.02). Urine output for all women at 12 and 18 h was 2.0 (0.7-5.7) and 1.9 (0.5-4.5)mL kg(-1)h(-1). Blood loss was 0.4 (0.2-0.8)L in women with oxytocin infusions and 0.3 (0.1-0.4)L in those without (P=0.003). Mean (SD) pre- and postoperative urine osmolality was 622.5 (185.7) and 293.0 (135.1) mosm/kg, respectively (P<0.0001). CONCLUSIONS Urine output varied widely between subjects, especially after the first 6h and was further reduced by the use of oxytocin infusion. This may have been a direct effect or related to increased blood loss in this group. Oxytocin use should be accounted for when setting a minimum postoperative urine output. We also found high pre-operative urine osmolalities suggesting significant dehydration.

Abstract
OBJECTIVE Flavocoxid is a medical food used for the clinical dietary management of osteoarthritis (OA). The acquisition cost of flavocoxid is higher than most traditional, generic NSAIDs. However, flavocoxid may have more favorable gastrointestinal (GI) toxicity resulting in lower overall costs. These costs have not been previously examined. This study provides a decision analytic model to assess the net costs of using flavocoxid for OA from a Medicare perspective. RESEARCH DESIGN AND METHODS A decision model was developed to estimate the total costs associated with flavocoxid versus naproxen for the management of Medicare patients with mild to moderate OA. Probabilities were obtained from literature and expert opinion, and costs were obtained from Medicare. Sensitivity analyses were conducted by varying probabilities and costs within clinically relevant ranges. RESULTS The base case resulted in flavocoxid having lower total annual costs ($1482 per patient) compared to naproxen ($1592). Flavocoxid remained the lowest cost option when the cost inputs were varied by 25% (above and below the base case), and when the probability of GI events with flavocoxid were varied by 25%. However, when GI rates from the literature and implied relative risks from the expert panel were used, or if the cost of PPIs was $0, then naproxen was the less costly alternative, though saving less than the annual cost of flavocoxid. Key limitations were the limited outcomes in the model (only GI events), lack of consideration of adherence or combination therapy, and the reliance on expert opinion due to a lack of data for flavocoxid. CONCLUSIONS In patients over 65 years of age who suffer from mild to moderate OA, flavocoxid may result in lower overall costs, despite a higher acquisition cost. Managed care organizations should consider total health care costs in the decision to include flavocoxid as a covered benefit.

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

Abstract
Pain has been reported to be a common problem in the general population and end-stage renal disease (ESRD) patients. Although similar data for pre-ESRD patients are lacking, we recently reported that the prevalence of pain is also very high (>70%) among pre-ESRD patients at a Los Angeles County tertiary referral centre. The high prevalence of pain in the CKD population is particularly concerning because pain has been shown to be associated with poor quality of life. Of greater concern, poor quality of life, at least in dialysis patients, has been shown to be associated with poor survival. We herein discuss the pathophysiology of common pain conditions, review a commonly accepted approach to the management of pain in the general population, and discuss analgesic-induced renal complications and therapeutic issues specific for patients with reduced renal function.

Abstract
Prostaglandins (PGs) with best-defined renal functions are PGE2 and prostacyclin (PGI2). These vasodilatory PGs increase renal blood flow and glomerular filtration rate under conditions associated with decreased actual or effective circulating volume, resulting in greater tubular flow and secretion of potassium. Under conditions of decreased renal perfusion, the production of renal PGs serves as an important compensatory mechanism. PGI2 (and possibly PGE2) increases potassium secretion mainly by stimulating secretion of renin and activating the renin-angiotensin system, which leads to increased secretion of aldosterone. In addition, PGE2 is involved in the regulation of sodium and water reabsorption and acts as a counterregulatory factor under conditions of increased sodium reabsorption. PGE2 decreases sodium reabsorption at the thick ascending limb of the loop of Henle probably via inhibition of the Na+-K+-2Cl- cotransporter type 2 (NKCC2). Cyclooxygenase inhibitors may enhance urinary concentrating ability in part through effects to upregulate NKCC2 in the thick ascending limb of Henle's loop and aquaporin-2 in the collecting duct. Thus, they may be useful to treat Bartter's syndrome and nephrogenic diabetes insipidus.

Abstract
Morphine sulfate (MS) stimulates mesangial cell (MC) proliferation, a process central to development of glomerular disease. The purpose of this study was to examine whether specific opioid receptors (OR) and signal transducer and activators of transcription 3 (STAT3) signaling are associated with MS-induced MC proliferation. C57Bl/6J and OR-specific knockout (KO) mice were treated for up to 6 wk with PBS, MS (0.7-2.14 mg/kg), naloxone (equimolar to MS), or MS+naloxone (n = 6 per group). Glomerular volume and expression of PCNA, Thy1, and ED1/CD68 were analyzed in kidney sections. Cell proliferation and STAT3 phosphorylation were analyzed by bromodeoxyuridine (BrdU) ELISA and Western blot, respectively, in MCs in vitro. MS treatment led to enlarged kidneys and glomerulopathy and naloxone reversed these effects. MS treatment increased glomerular volume in both mu-OR (MOR) KO and delta-OR (DOR) KO mice, but not in kappa-OR (KOR) KO mice. To ascertain that MS-induced glomerulopathy in vivo was due to MC proliferation, we further examined the OR-specific effects of MS in MCs in vitro. MS-induced MC proliferation in vitro was inhibited by KOR-specific nor-BNI, but not by DOR or MOR-specific antagonists naltrindol or CTOP, respectively. KOR-specific agonist U50488H stimulated proliferation of MCs, but DOR-specific agonist DPDPE and MOR-specific agonist DAMGO did not. MS failed to stimulate proliferation of MCs from KOR KO mice. MS and KOR agonists induced STAT3 phosphorylation, and STAT3 inhibitor blocked KOR agonist-induced MC proliferation. We show that MS stimulates glomerulopathy and MC proliferation via KOR and STAT3 signaling.

Abstract
The common adverse effects of traditional nonsteroidal antiinflammatory drugs on renal function include reductions in renal blood flow, glomerular filtration rate, and sodium and potassium excretion, mainly via inhibition of renal cyclooxygenase. We designed the present study to determine the effects of IV paracetamol or parecoxib on renal function in elderly patients undergoing orthopedic surgery. Seventy-five patients (76 +/- 8 yr, mean +/- sd) undergoing hip replacement or surgery of the femoral shaft completed this randomized and placebo-controlled study. After their arrival in the postanesthesia care unit, patients received an initial dose of the study medication, paracetamol 1000 mg IV (n = 25), parecoxib 40 mg IV (n = 25), or saline IV (n = 25); subsequent doses were administered for the next 3 days. Opioids were provided as rescue medication. Blood and urine samples were collected before and after surgery, and markers of renal function were determined. During the first 2 h after the initial dose of parecoxib, creatinine clearance was slightly diminished (125 +/- 83 to 86 +/- 45 mL/min, P < 0.05), whereas no significant decrease of creatinine clearance was observed in the placebo and paracetamol groups. After all treatments, sodium and potassium excretion as well as urine albumin and alpha-1-microglobulin were transiently increased (group differences: not signicifant). In conclusion, glomerular and tubular functions were transiently affected in all patients after orthopedic surgery; however, the differences between the treatment groups were small and not clinically relevant. Further studies are warranted to determine adverse renal effects of longer-lasting therapy with these drugs, especially in patients with renal impairment or concomitant diseases.

Abstract
Glomerular tip lesion and its relation to different glomerular diseases is a subject of controversy. The therapeutic and prognostic clinical implications of glomerular tip lesions are ambiguous. We present a case of glomerular tip lesion associated with nonsteroidal anti-inflammatory drug-induced nephrotic syndrome that further complicates this issue. To our knowledge, this is the first case report of glomerular tip lesion associated with nonsteroidal anti-inflammatory drug-induced nephrotic syndrome.

Abstract
OBJECTIVE To study the functional status and health-related quality of life (HRQOL) of patients with rheumatoid arthritis (RA) after treatment with celecoxib, compared with placebo and naproxen. METHODS This was a prospective, randomized, double-blind, parallel group trial conducted at 79 sites in the United States and Canada over a 12-week treatment period. Patients were randomly assigned to 5 groups: placebo, 100 mg twice a day of celecoxib, 200 mg twice a day of celecoxib, 400 mg twice a day of celecoxib, and 500 mg twice a day of naproxen. The Health Assessment Questionnaire (HAQ) disability index was used to measure functional status. The Medical Outcomes Study Short Form 36 (SF-36) was used to measure general HRQOL. RESULTS Enrollees were 1,149 patients with diagnosed and active RA. At the end of the treatment period, patients in the 4 active treatment groups had significant improvement in both functional status and overall HRQOL in comparison with the placebo group. Patients in the twice-daily 100 mg celecoxib group significantly differed from placebo at weeks 2 and 6 on HAQ scores and at week 12 on 5 domains and both summary scores of the SF-36. Patients treated with twice-daily 200 mg celecoxib had significantly better functional status than placebo at all times of testing with the HAQ, and also had significantly better function than those treated with naproxen after 2 and 12 weeks of treatment. Patients in the twice-daily 200 mg and 400 mg celecoxib groups showed similar improvement in HRQOL as determined by the 8 domain scores and 2 summary scores of the SF-36. CONCLUSION Celecoxib was better than placebo and comparable with naproxen in improving functional status and overall HRQOL among RA patients.

Abstract
Moderate to severe pain frequently accompanies chronic diseases in general and end-stage renal disease (ESRD) in particular. Several analgesic agents and associated metabolites show altered pharmacokinetics in the presence of reduced glomerular filtration rate. Drug-related side effects may exacerbate symptoms frequently observed in persons with chronic kidney disease (CKD; eg, fatigue, nausea, vomiting, and constipation) or those often attributed to hemodialysis therapy (eg, orthostatic hypotension and impaired cognition). Persons with advanced CKD and ESRD are at increased risk for adverse effects of analgesic agents because of enhanced drug sensitivity, comorbid conditions, and concurrent medication use. Dose adjustment and avoidance of certain analgesics may be required in patients with advanced CKD and ESRD. We review the available evidence on pharmacokinetics and adverse drug effects of various analgesic agents commonly used in patients with advanced CKD and ESRD. Determining an optimal approach to the control of pain in patients with advanced CKD and ESRD will require additional research.

Abstract
Although the coxibs have demonstrated superior gastrointestinal safety compared to traditional non-selective NSAIDs, questions remain regarding their effects on the renal and cardiovascular systems. In terms of renal function, both Type 1 and Type 2 cyclooxygenase (COX-1 and COX-2) are expressed constitutively in the kidney. Prostaglandins do not play a major role in the maintenance of renal function in healthy individuals but they become profoundly important in certain clinical situations such as renal stress, or volume depletion. In such situations the effects of the coxibs and non-selective NSAIDs are likely to be similar. The incidence of renal side effects is low (1-5%) and the patients at risk of renal complications are well defined and can usually be identified prospectively and followed up as appropriate. From the cardiovascular point of view, questions have been raised as to whether the coxibs have a prothrombotic effect. Here we review the available evidence and consider various hypotheses for an apparent increase in cardiovascular events reported in one coxib study (the VIGOR trial). Because of a lack of anti-platelet activity, coxibs are not suited for the provision of cardiovascular prophylaxis, and in patients at risk of myocardial infarction the prophylactic use of aspirin should always be considered. Although evidence suggests that use of coxibs with low-dose aspirin is safer than the combination of traditional NSAIDs with aspirin, further studies are required to confirm that this is the case.

Abstract
The diuretic response to loop diuretics in various disease states has consistently been found to be subnormal. One of the key determinants of the degree of diuretic response is the functional integrity of the sodium-potassium-chloride transporter in the loop of Henle. Studies in animal models suggest that expression/activity of the transporter may be affected by factors such as altered natural splicing events of NKCC2 (the gene encoding for the renal transporter), renal prostanoids, vasopressin, and other autacoids. We have reviewed the pharmacokinetics and pharmacodynamics of loop diuretics in health and in edematous disorders for which they are used. On the basis of evidence reviewed in this paper, we propose that altered expression or activity of the sodium-potassium-chloride transporter in the loop of Henle, in conjunction with events occurring in other segments of the nephron, possibly accounts for the altered diuretic response to these agents. Thus the modulators of this altered expression/activity could serve as important therapeutic targets for alternative diuretic regimens in these conditions.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are well known to cause fluid and electrolyte abnormalities and renal failure. NSAIDs also may cause an acute allergic interstitial nephritis (AIN) and the nephrotic syndrome, characterized by histologic pathology consistent with minimal change disease in patients with previously normal renal function. The nephrotoxic potential of cyclooxygenase 2 (COX-2) inhibitors has not been established because AIN associated with nephrotic syndrome has not been reported secondary to the COX-2 inhibitors. This case report describes the first case of AIN associated with nephrotic syndrome in a patient treated with the selective COX-2 inhibitor, celecoxib.

Abstract
UNLABELLED Experimental arthritis in rats results in a growth failure and a decrease in circulating and hepatic concentrations of insulin-like growth factor I (IGF-I). Renal damage has also been reported in arthritic rats. The aim of this study was 1) to analyse if alterations in the IGF-I system in the kidney occurs in adjuvant-induced arthritis and 2) to analyse if recombinant human GH (rhGH) administration is able to reverse these effects. Male Wistar rats were injected with complete Freund's adjuvant or vehicle and 22 days later they were killed. Arthritis increased serum creatinine levels, relative kidney weight and IGF-I concentrations in this organ. In a second experiment, arthritic and control rats received rhGH (3 UI/Kg sc) or 250 microl saline from day 14, after adjuvant or vehicle injection, until day 22. IGF-I concentrations were higher in both the renal cortex and medulla of arthritic rats. In contrast, kidney IGF-I mRNA was lower in both areas of arthritic animals. GH treatment significantly decreased serum creatinine levels and IGF-I concentrations in the kidney cortex and medulla of arthritic rats. However, the administration of rhGH to arthritic animals significantly increased the IGF-I gene expression in both the renal cortex and medulla. Serum and kidney concentrations of IGF-I binding proteins (IGFBPs) were increased in arthritic animals and they were reduced by GH administration. CONCLUSION These data suggest that experimental arthritis causes renal dysfunction and GH treatment can ameliorate this effect.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) are widely used. These agents are associated with adverse renal effects caused by the reduction in synthesis of renal prostaglandins through inhibition of cyclooxygenase (COX). Both isoforms of COX, COX-1 and COX-2, are expressed in the kidney in constitutive and inducible forms. It is assumed therefore that the COX-2-selective inhibitors, rofecoxib and celecoxib, would have an effect on renal function similar to that of nonselective NSAIDs. Several studies have evaluated this issue, although they have different study models and some have design flaws that limit their interpretation. Therefore, conclusions should be based on the pattern of observed effects rather than on individual data. These studies suggest that both celecoxib and rofecoxib can cause sodium retention and decrease glomerular filtration rate (GFR) to a similar extent as nonselective NSAIDs in patients at risk for adverse renal effects. Consequently, the same precautions regarding renal risk that are followed for nonselective NSAIDs should be used when selective COX-2 inhibitors are administered.

Abstract
OBJECTIVE Nonsteroidal anti-inflammatory drugs (NSAIDs) block prostaglandin production by inhibiting cyclooxygenase (COX); they are believed to cause gastroduodenal damage by inhibiting the COX-1 isoform and to have analgesic and anti-inflammatory effects by inhibiting the COX-2 isoform. As compared to conventional NSAIDs, celecoxib, a COX-2 specific inhibitor, has been shown in previous single posttreatment endoscopy studies to be associated with lower gastroduodenal ulcer rates. In response to concerns that such studies may under-represent ulceration rates, the present serial endoscopy study was designed to compare cumulative gastroduodenal ulcer rates associated with the use of celecoxib to those of naproxen, a conventional NSAID. METHODS In this double-blind, parallel-group, multicenter study, 537 patients with osteoarthritis (OA) or rheumatoid arthritis (RA) were randomized to treatment with celecoxib 200 mg b.i.d. (n = 270) or naproxen 500 mg b.i.d. (n = 267) for 12 wk. Gastroduodenal damage was determined from esophagogastroduodenoscopy after 4, 8, and 12 wk of therapy. Arthritis efficacy was evaluated with Patient's and Physician's Global Assessments. RESULTS Gastroduodenal ulcer rates after celecoxib and naproxen treatment were 4% versus 19% in the 0-4 wk interval (p < 0.001), 2% versus 14% in the 4-8 wk interval (p < 0.001), and 2% versus 10% in the 8-12 wk interval (p < 0.001), respectively. After 12 wk of treatment, the cumulative incidence of gastroduodenal ulcers was 9% with celecoxib and 41% with naproxen. In the celecoxib group, gastroduodenal ulcers were significantly associated with Helicobacter pylori status (p < 0.05), concurrent aspirin usage (p = 0.001), and a history of ulcer (p = 0.010), but not with disease type (OA/RA), age, gender, other relevant medical histories, or concurrent corticosteroid or disease-modifying antirheumatic drugs usage (p > 0.05). Celecoxib produced a significantly lower incidence rate of both gastric (p < 0.001) and duodenal (p < 0.030) ulcers. The two agents produced similar improvements in Patient's and Physician's Global Assessments of arthritis efficacy. The incidence of adverse events and withdrawal rates did not differ significantly between treatments. CONCLUSIONS As compared to naproxen (500 mg b.i.d.), use of celecoxib (200 mg b.i.d.), a COX-2 specific agent, at the recommended RA dose and twice the most frequently prescribed OA dose, was associated with lower rates of gastric, duodenal, and gastroduodenal ulcers but had comparable efficacy, in patients with OA and RA.

Abstract
BACKGROUND This study evaluates the impact of celecoxib on functional status, health-related quality of life (HRQOL), and safety of elderly patients (> or =70 years) with osteoarthritis (OA) of the knee and/or hip. METHODS Data were pooled from three prospective, randomized, multicenter, double-blind, parallel group trials, each having a 12-week treatment period. Multicenter studies were conducted in the United States and Canada. Data for patients diagnosed with active OA of the knee and/or hip in a flare state who were 70 years of age and older were included in the comparison of therapeutic doses of celecoxib or naproxen versus placebo (N = 768). Elderly patients from each of the three trials who were randomly assigned to groups treated with a placebo. 200 mg/day of celecoxib, 400 mg/ day of celecoxib, or 1000 mg/day of naproxen were included in this analysis. The Western Ontario and McMaster Universities Osteoarthritis Index was used to measure functional status. The Short Form-36 was used as a general measure of HRQOL. Safety was assessed according to the incidence and type of adverse reactions as reported by the patients and the rate of withdrawal due to adverse events. RESULTS At the end of the treatment period, patients in the celecoxib groups had significant improvement in both functional status and HRQOL in comparison with the placebo group. The effects of total daily doses of 200 mg of celecoxib, 400 mg of celecoxib, and 1000 mg of naproxen on functioning and HRQOL were not found to be significantly different from each other. The incidence of serious adverse events and withdrawal from the studies due to adverse events were similar in the celecoxib groups as they were in the placebo group. Overall, the naproxen group reported a significantly higher incidence of gastrointestinal adverse events than did the placebo and the 200-mg-daily celecoxib groups. CONCLUSIONS This study showed that celecoxib and naproxen significantly improved functional status and HRQOL in elderly patients compared with those treated with a placebo. Celecoxib-treated patients were also found to experience safety and tolerability similar to that of the placebo-treated patients.

Abstract
Nonsteroidal anti-inflammatory drugs (NSAIDs) can affect renal function in a variety of ways. The most important clinical effects are decreased sodium excretion, decreased potassium excretion, and declines in renal perfusion. Decreased sodium excretion can result in weight gain, peripheral edema, attenuation of the effects of antihypertensive agents, and rarely precipitation of chronic heart failure. Hyperkalemia can occur to a degree sufficient to cause cardiac arrhythmias. Renal function can decline sufficiently enough to cause acute renal failure. Risk factors for all of these effects have been identified, allowing prospective identification of patients at risk with institution of appropriate precautionary measure. All NSAIDs seem to share these adverse effects. Preliminary data from cyclooxygenase-2-selective inhibitors suggest that they also affect renal prostaglandins. Therefore, the same cautions should be exercised with their use as with traditional NSAIDs.

Abstract
STUDY OBJECTIVE To evaluate the functional status of patients with signs and symptoms of osteoarthritis of the knee after treatment with celecoxib compared with placebo and naproxen. DESIGN Prospective, randomized, double-blind, parallel-group, 12-week trial. SETTING Multicenter study conducted at 71 sites in the United States and Canada. PATIENTS One thousand four patients with active osteoarthritis of the knee in a flare state. INTERVENTIONS Patients were assigned randomly to one of five treatment groups: placebo; celecoxib 50 mg twice/day, 100 mg twice/day, and 200 mg twice/day; and naproxen 500 mg twice/day. MEASUREMENTS AND MAIN RESULTS The Western Ontario and McMaster Universities Osteoarthritis Index was used to measure functional status. At the end of the treatment period, patients in the four active treatment groups had significantly better functional status than those receiving placebo. Patients treated with celecoxib 100 mg twice/day had significantly better improvements in pain scores than those treated with placebo and naproxen. CONCLUSION Celecoxib was better than placebo and comparable with naproxen in improving aspects of functional status in patients with osteoarthritis.

Abstract
Heart failure is a clinical syndrome that is predominantly caused by cardiovascular disorders such as coronary heart disease and hypertension. However, several classes of drugs may induce heart failure in patients without concurrent cardiovascular disease or may precipitate the occurrence of heart failure in patients with preexisting left ventricular impairment. We reviewed the literature on drug-induced heart failure, using the MEDLINE database and lateral references. Successively, we discuss the potential role in the occurrence of heart failure of cytostatics, immunomodulating drugs, antidepressants, calcium channel blocking agents, nonsteroidal anti-inflammatory drugs, antiarrhythmics, beta-adrenoceptor blocking agents, anesthetics and some miscellaneous agents. Drug-induced heart failure may play a role in only a minority of the patients presenting with heart failure. Nevertheless, drug-induced heart failure should be regarded as a potentially preventable cause of heart failure, although sometimes other priorities do not offer therapeutic alternatives (e.g., anthracycline-induced cardiomyopathy). The awareness of clinicians of potential adverse effects on cardiac performance by several classes of drugs, particularly in patients with preexisting ventricular dysfunction, may contribute to timely diagnosis and prevention of drug-induced heart failure.

Abstract
We assessed the effects of nabumetone, sulindac, and placebo on renal function and renal excretion of vasodilatory prostaglandins in older female patients (age >50 years) with osteoarthritis and normal renal function. Using a prospective, crossover design, we compared the effects of nabumetone 2000 mg/d and sulindac 400 mg/d with placebo on glomerular filtration rate (GFR), renal plasma flow (RPF), and urinary excretion of prostaglandin E2 and 6-keto-prostaglandin F1alpha in 12 patients. Urinary excretion of vasodilatory prostaglandins was not decreased after 14 days of treatment with either nabumetone or sulindac. Likewise, treatment with nabumetone or sulindac did not significantly alter renal function compared with placebo. There were no differences in mean changes in GFR or RPF from baseline after treatment with nabumetone or sulindac compared with placebo. The mean (+/- SD) changes in GFR from baseline were 0%+/-8% in patients receiving nabumetone, -8%+/-15% in patients receiving sulindac, and -7%+/-15% in patients receiving placebo. The results of this study demonstrate that treatment with nabumetone or sulindac caused no deterioration in renal function in older female patients with osteoarthritis and normal renal function.

Abstract
AIMS To study the mechanisms behind NSAID-associated nephropathy. METHODS Analysis of published case reports satisfying strict criteria for NSAID nephropathy. RESULTS Ninety-seven cases with acute nephritis (AN; 19 patients), minimal change nephropathy (MC; 38 patients), membranous glomerulonephritis (MGN; 19 patients), focal sclerosis (FS; 13 patients) and other glomerulonephritis subgroups (8 patients) were identified. Hypersensitivity reactions were seen in all groups, most often in AN. Proteinuria was more severe in MC and FS than in MGN and unrelated to amount of glomerular deposits. The mean NSAID treatment time was 1.7 months in AN, 8.2 months in MC and 39 months in MGN and associated with amount of glomerular deposits, fusion of podocytes and proteinuria, and inversely associated with hypersensitivity, interstitial damage and renal failure. Rheumatic diseases were common in MGN. At follow-up 68 of 72 patients who had discontinued NSAID treatment had improved, 57 with normal renal function. CONCLUSIONS NSAID nephropathy may be caused by hypersensitivity. The reaction is milder than in drug-induced acute tubulointerstitial nephritis, probably because the offending drug inhibits the inflammatory reaction it has started itself. Heavy proteinuria is probably due to lymphokines produced as a result of the immunological response. If the allergic reaction is strong, AN is produced rapidly with severe renal failure but little proteinuria; if it is less violent, immunocompetent cells may develop to produce lymphokines and proteinuria. Immune complexes may be formed eventually, secondary to the increased glomerular permeability, more easily in patients with a hyperactive immune system and with little consequence for renal function.

Abstract
UNLABELLED MODE OF ACTION OF NON-STEROIDAL ANTI-INFLAMMATORY DRUGS: Non-steroidal anti-inflammatory drugs (NSAID) exert their major therapeutic and adverse effects by inhibition of prostanoid synthesis. Also the interactions with antihypertensive drugs and lithium are caused by this mechanism of action. Cyclooxygenation is a key enzymatic step in the synthesis of prostanoids. 1990 2 isoforms of the enzyme cyclooxygenase have been identified: Prostanoids synthesized by the constitutive cyclooxygenase (COX-1) are involved in physiological homeostasis. In contrast, the inducible cyclooxygenase (COX-2) produces large amounts of prostanoids, mainly contributing to the pathophysiological process of inflammation. COX-2 SELECTIVE NSAID: The discovery of the cyclooxgenase-isoenzymes ushered in a new generation of NSAID: A drug with selectivity for COX-2 would inhibit proinflammatory prostanoid synthesis while sparing physiologic prostanoid synthesis. Thus, a selective COX-2 inhibitor should be anti-inflammatory with less or no gastrointestinal or other NSAID-typical adverse effects. The experiences with currently used NSAID, which show an increasing incidence of side effects as COX-1 inhibition increases, and studies with the COX-2 selective NSAID salsalate and meloxicam, which have less adverse effects than nonselective COX inhibitors in equivalent antiphlogistic dosage, prove the concept of selective COX-2 inhibition to avoid the NSAID typical side effects. Newly developed drugs with a very high selectivity for COX-2 are now tested in clinical trials. CONCLUSION So far the results suggest, that selective and highly selective COX-2 inhibitors have significantly fewer gastrointestinal and renal adverse effects and do not inhibit platelet aggregation.

Abstract
NSAID use is pervasive in our society. Existing NSAIDs pose little risk to patients who tolerate them early during their administration. Among persons with normal renal function who have no other risk factors (dehydration) for an acute hemodynamic effect, there is no risk. However, NSAID administration to susceptible persons may cause decrements in renal plasma flow and glomerular filtration rate within hours. This acute hemodynamic effect is the most common renal syndrome caused by NSAIDs. With careful monitoring, this effect is readily detected with routine clinical laboratory tests (serum creatinine and/or blood urea nitrogen concentrations). However, patients who continue administration of NSAIDs in this setting risk acute tubular necrosis and permanent damage to the kidney. Newer NSAIDs that selectively inhibit cyclooxygenase-2: cyclooxygenase-1 ratio may provide a more favorable risk profile for patients who cannot tolerate existing drugs.
