Abstract
Introduction: Sepsis-associated acute kidney injury (SA-AKI) is a complication of sepsis and is characterized by high mortality. Aspirin affects cyclooxygenases which play a significant role in inflammation, hemostasis, and immunological regulation. Sepsis is an uncontrolled inflammatory and procoagulant response to a pathogen, but aspirin can inhibit platelet function to attenuate the inflammatory response, thus improving outcomes. Several studies have generated contradictory evidence regarding the effect of aspirin on patients with sepsis-associated acute kidney injury (SA-AKI). We conducted an analysis of the MIMIC IV database to investigate the correlation between aspirin utilization and the outcomes of patients with SA-AKI, as well as to determine the most effective dosage for aspirin therapy. Materials and methods: SA-AKI patients' clinical data were extracted from MIMIC-IV2.1. Propensity score matching was applied to balance the baseline characteristics between the aspirin group and the non-user group. Subsequently, the relationship between aspirin and patient death was analyzed by Kaplan-Meier method and Cox proportional hazard regression models. Results: 12,091 patients with SA-AKI were extracted from the MIMIC IV database. In the propensity score-matched sample of 7,694 individuals, lower 90-day mortality risks were observed in the aspirin group compared to the non-users group (adjusted HR: 0.722; 95%CI: 0.666, 0.783) by multivariable cox proportional hazards analysis. In addition, the Kaplan-Meier survival curves indicated a superior 90-day survival rate for aspirin users compared to non-users (the log-rank test p-value was 0.001). And the median survival time of patients receiving aspirin treatment was significantly longer than those not receiving (46.47 days vs. 24.26 days). In the aspirin group, the average ICU stay length was shorter than non-users group. (5.19 days vs. 5.58 days, p = 0.006). There was no significant association between aspirin and an increased risk of gastrointestinal hemorrhage (p = 0.144). Conclusion: Aspirin might reduce the average ICU stay duration and the 30-day or 90-day mortality risks of SA-AKI patients. No statistically significant difference in the risk of gastrointestinal hemorrhage was found between the aspirin group and the control group.

Abstract
BACKGROUND Epidemiologic data suggest that analgesic use increases the risk of renal cell cancer (RCC), but few prospective studies have been published. We investigated the association between analgesic use and RCC in 2 large prospective studies. METHODS We examined the relationship between analgesic use and RCC risk in the Nurses' Health Study and the Health Professionals Follow-up Study. Use of aspirin, other nonsteroidal anti-inflammatory drugs (NSAIDs), and acetaminophen was ascertained in 1990 in the Nurses' Health Study and in 1986 in the Health Professionals Follow-up Study, and every 2 years thereafter. We evaluated baseline and duration of use of analgesics. RESULTS During follow-up of 16 years among 77,525 women and 20 years among 49,403 men, we documented 333 RCC cases. Aspirin and acetaminophen use were not associated with RCC risk. However, regular use of nonaspirin NSAIDs was associated with an increased RCC risk; the pooled multivariate relative risk was 1.51 (95% confidence interval, 1.12-2.04) at baseline. The absolute risk differences for users vs nonusers of nonaspirin NSAIDs were 9.15 per 100 000 person-years in women and 10.92 per 100,000 person-years in men. There was a dose-response relationship between duration of nonaspirin NSAID use and RCC risk; compared with nonregular use, the pooled multivariate relative risks were 0.81 (95% confidence interval, 0.59-1.11) for use less than 4 years, 1.36 (0.98-1.89) for 4 to less than 10 years, and 2.92 (1.71-5.01) for use for 10 or more years (P < .001 for trend). CONCLUSION Our prospective data suggest that longer duration of use of nonaspirin NSAIDs may increase the risk of RCC.

Abstract
Aspirin is widely used as an antiinflammatory drug especially in children with rheumatic fever arthritis. The diminishing effects of aspirin on antioxidant enzymes and hepato-renal systems at high doses are well-known. It is now evident that the damage at antioxidant system worsens the clinical picture of the disease and prolongs the treatment time. Thus, we investigated the effect of antioxidant enzyme cofactors-zinc and selenium-supplementation on superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and malondialdehyde (MDA) levels (erythrocyte and liver) and hepato-renal toxicity during aspirin treatment at therapeutic doses. The rats were divided into five groups. The first and second groups were given aspirin 75 mg/kg/day and aspirin plus selenium (Selenium 200, selenium 200 mg tablet as selenium yeast, GNC) and zinc (Zinc 100, zinc 100 mg tablet as zinc gluconate, GNC), respectively, the third and fourth take 50 mg/kg/day aspirin and aspirin plus selenium and zinc twice a day, respectively. The fifth group was control. The rats were treated with aspirin for 5 weeks as in the treatment of rheumatic fever arthritis in children. Erythrocyte SOD and MDA levels were preserved with supplementation, whereas there was no change for GSH-Px levels. Liver SOD, GSH-Px, and MDA levels were not changed. In zinc- and selenium-supplemented groups, the levels of serum alanine aminotransferase, uric acid, and direct bilirubin levels were found statistically decreased compared with nonsupplemented groups. There was no significant histopathologic change in specimens of hepatic and renal tissues. Trace element supplementation may prevent free radical damage and shorten treatment time in children using long-term aspirin treatment.

Abstract
The antimalaria drug chloroquine is often taken against a background of analgesic nephropathy caused by nonsteroidal anti-inflammatory drugs such as paracetamol (acetaminophen). Chloroquine has marked effects on the normal kidney and stimulates an increase in plasma vasopressin via nitric oxide. The aim of this study was to determine the renal action of chloroquine in a model of analgesic nephropathy. Sprague-Dawley rats (n = 6-8/group) were treated with paracetamol (500 mg kg(-1) day(-1)) for 30 days in drinking water to induce analgesic nephropathy; control rats received normal tap water. Under intraval anesthesia (100 mg kg(-1)) rats were infused with 2.5% dextrose for 3 h to equilibrate and after a control hour they received either vehicle, chloroquine (0.04 mg h(-1)), N(omega)-nitro-L-arginine methyl ester (L-NAME, nitric-oxide synthase inhibitor, 60 micro g kg(-1) h(-1)) or combined chloroquine and L-NAME over the next hour. Plasma was collected from a parallel group of animals for vasopressin radioimmunoassay. Long-term paracetamol treatment resulted in a decrease in glomerular filtration rate (p < 0.05), sodium excretion (p < 0.001), and urine osmolality (p < 0.001), but no change in urine flow rate compared with untreated animals. Chloroquine administration in paracetamol treated rats induced a significant reduction (p < 0.05) in urine flow rate and a significant increase in plasma vasopressin (p < 0.001). These effects were blocked by coadministration of L-NAME and thus seem to be mediated by a pathway involving nitric oxide. However, these responses contrast with the chloroquine-induced diuresis previously observed in untreated rats, possibly reflecting paracetamol inhibition of renal prostaglandin synthesis and consequent moderation of vasopressin's action.

Abstract
Renal papillary necrosis (RPN) is a significant problem in human beings, especially in England and in Australia where it has been reported to account for 15% to 20% of patients needing renal transplants. Many compounds, including aspirin, phenacetin, phenylbutazone, indomethacin, mefenamic acid, flufenamic acid, fenoprofin, naproxen, and ibuprofen have been linked to renal papillary necrosis in human beings. Although the exact mechanism of RPN is unknown, there are several theories that have good scientific evidence behind them. Study of RPN in animals as models for the disease in human beings is limited by several factors, including anatomical differences between human beings and most animal species as well as technical difficulties in studying the renal papilla.

Abstract
Phenacetin-based analgesics have been linked to the development of renal pelvis cancer and renal cell carcinoma (RCC). The relationship between non-phenacetin types of analgesics and kidney cancer is less clear, although laboratory evidence suggests that these drugs possess carcinogenic potential. A population-based case-control study involving 1204 non-Asian RCC patients aged 25-74 and an equal number of sex-, age- and race-matched neighbourhood controls was conducted in Los Angeles, California, to investigate the relationship between sustained use of analgesics and risk of RCC according to major formulation categories. Detailed information on medical and medication histories, and other lifestyle factors was collected through in-person interviews. Regular use of analgesics was a significant risk factor for RCC in both men and women (odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.4-1.9 for both sexes combined). Risks were elevated across all four major classes of analgesics (aspirin, non-steroidal anti-inflammatory agents other than aspirin, acetaminophen and phenacetin). Within each class of analgesics, there was statistically significant increasing risk with increasing level of exposure. Although there was some minor variability by major class of formulation, in general individuals in the highest exposure categories exhibited approximately 2.5-fold increase in risk relative to non- or irregular users of analgesics. Subjects who took one regular-strength (i.e. 325 mg) aspirin a day or less for cardiovascular disease prevention were not at an increased risk of RCC (OR = 0.9, 95% CI = 0.6-1.4).

Abstract
Overuse and abuse of phenacetin-containing mixed analgesics has contributed to end-stage renal disease. Combination analgesics, especially those coformulated with caffeine, have been implicated as imparting a greater risk of analgesic-associated nephropathy (AAN) than single or coformulated analgesics without caffeine. This has led to a recommendation that the sale of "two plus caffeine" analgesic mixtures be reclassified from over-the-counter to prescription only availability. There is a rational basis for coformulating acetylsalicylic acid (ASA) and acetaminophen (paracetamol) as this reduces the dose of each, without altering efficacy. The coformulation of caffeine with these analgesics has a significant adjuvant effect and increases analgesic efficacy 1.4-1.6-fold. Currently available animal and human data do not support the notion that the nephrotoxic risk from coformulated ASA and acetaminophen is higher than the risk from either ASA or acetaminophen alone, in equivalent analgesic doses. There are no epidemiological data that implicate caffeine in AAN, and only limited evidence that links excessive acetaminophen usage to renal disease. There is no evidence that caffeine increases analgesics papillotoxicity directly. The presence of caffeine in mixtures of analgesics are no more addictive than other sources of caffeine. There is no evidence to suggest that adding caffeine to analgesic mixtures enhances the potential for promoting analgesic misuse in the general population. Thus distinct therapeutic benefits of ASA, acetaminophen and caffeine appear to outweigh any known risk. It is doubtful if preventing the availability of these products will significantly affect the role of analgesic abuse/overuse in end-stage renal disease. Better risk management would come from a focused educational program, developed in a close collaboration between industry, healthcare professionals and consumer organizations, such a program must warn against the potential dangers of analgesic and non-steroidal anti-inflammatory drug misuse.

Abstract
Analgesics and nonsteroidal anti-inflammatory drugs (NSAIDs) are well recognized as a major class of therapeutic agent that causes renal papillary necrosis (RPN). Over the last decade a broad spectrum of other therapeutic agents and many chemicals have also been reported that have the potential to cause this lesion in animals and man. There is consensus that RPN is the primary lesion that can progress to cortical degeneration; and it is only at this stage that the lesion is easily diagnosed. In the absence of sensitive and selective noninvasive biomarkers of RPN there is still no clear indication of which compound, under what circumstances, has the greatest potential to cause this lesion in man. Attempts to mimic RPN in rodents using analgesics and NSAIDs have not provided robust models of the lesion. Thus, much of the research has concentrated on those compounds that cause an acute or subacute RPN as the basis by which to study the pathogenesis of the lesion. Based on the mechanistic understanding gleaned from these model compounds it has been possible to transpose an understanding of the underlying processes to the analgesics and NSAIDs. The mechanism of RPN is still controversial. There are data that support microvascular changes and local ischemic injury as the underlying cause. Alternatively, several model papillotoxins, some analgesics, and NSAIDs target selectively for the medullary interstitial cells, which is the earliest reported aberration, after which there are a series of degenerative processes affecting other renal cell types. Many papillotoxins have the potential to undergo prostaglandin hydroperoxidase-mediated metabolic activation, specifically in the renal medullary interstitial cells. These reactive intermediates, in the presence of large quantities of polyunsaturated lipid droplets, result in localized and selective injury of the medullary interstitial cells. These highly differentiated cells do not repair, and it is generally accepted that continuing insult to these cells will result in their progressive erosion. The loss of these cells is thought to be central to the degenerative cascade that affects the cortex. There is still a need to understand better the primary mechanism and the secondary consequences of RPN so that the risk of chemical agents in use and novel molecules can be fully assessed.

Abstract
While it is clear that humans suffer from "classic" analgesic nephropathy, the causative agents and mechanisms are still not known. A review of the literature revealed that chronic acetaminophen exposure does not produce renal papillary necrosis in rodents or humans. In contrast, while chronic aspirin exposure to rodents results in renal papillary necrosis with renal morphological and functional changes similar to that described in humans, epidemiological studies do not implicate aspirin alone in human analgesic nephropathy. The difference in the effects of aspirin in humans and rats may be due to the inability of epidemiological studies to detect aspirin-induced analgesic nephropathy or more likely to the fact that species differences exist, with the rat being more sensitive than humans. With respect to combinations of aspirin and acetaminophen, with or without caffeine, there are minimal tightly controlled studies. In addition, there is little evidence of enhanced renal papillary necrosis in rodents treated with aspirin and acetaminophen combinations. In summary, it remains to be determined what chemical entities cause "classic" analgesic nephropathy in humans and the mechanisms of this toxicity such that preventative measures can be instituted. Elucidation of the mechanisms of analgesic nephropathy has been hampered due to the lack of animal models that closely mimic the human disease. Rodents do not appear to be an appropriate model.

Abstract
The mammalian urinary tract includes the kidneys, ureters, urinary bladder, and urethra. The renal parenchyma is composed of the glomeruli and a heterogeneous array of tubule segments that are specialized in both function and structure and are arranged in a specific spatial distribution. The ultrastructure of the glomeruli and renal tubule epithelia have been well characterized and the relationship between the cellular structure and the function of the various components of the kidney have been the subject of intense study by many investigators. The lower urinary tract, the ureters, urinary bladder, and urethra, which are histologically similar throughout, are composed of a mucosal layer lined by transitional epithelium, a tunica muscularis, and a tunica serosa or adventitia. The present manuscript reviews the normal ultrastructural morphology of the kidney and the lower urinary tract. The normal ultrastructure is illustrated using transmission electron microscopy of normal rat kidney and urinary bladder preserved by in vivo perfusion with glutaraldehyde fixative and processed in epoxy resin.

Abstract
There are conflicting reports on the ability of aspirin as a single agent to cause acute or chronic renal failure in experimental animals. Chronic administration of aspirin alone over 18 to 68 weeks in doses of 120 to 500 mg/kg/d has been reported to cause renal papillary necrosis in rats. However, some investigators have been unable to produce renal papillary necrosis in other species or in rats given lower divided doses comparable to therapeutic doses used in humans. In a variety of rat strains, aspirin administered as a single high dose intravenously or by oral gavage produces acute tubular necrosis of proximal tubules, rarely accompanied by renal papillary necrosis in susceptible strains. Several human studies have addressed the chronic nephrotoxicity of aspirin alone or relative risk of end-stage renal disease in association with aspirin use after correction for other analgesics. With the exception of one case control study demonstrating a low, but statistically significant risk of end-stage renal disease in association with aspirin use, all other case control studies and several prospective studies have been unable to identify a significant risk of chronic renal failure in patients using aspirin alone in therapeutic doses. In healthy adults, short-term aspirin administration in therapeutic doses has no effect on creatinine clearance, urine volume, osmolar clearance, or sodium and potassium excretion. However, in predisposed individuals with glomerulonephritis, cirrhosis, and chronic renal insufficiency, and in children with congestive heart failure, short-term aspirin use in therapeutic doses may precipitate reversible acute renal failure. Acute aspirin intoxication (>300 mg/kg) frequently causes acute renal failure and doses of 500 mg/kg may be lethal. Chronic salicylate intoxication has been reported to cause reversible or irreversible acute renal failure in association with a pseudosepsis syndrome.

Abstract
The nonnarcotic analgesics have been implicated as a significant cause of chronic renal failure worldwide. Epidemiologic studies of habitual abuse and necropsy studies show a strong relationship between the two. Animal studies designed to elucidate underlying mechanisms have been hampered because the lesion occurs infrequently and only after very high doses are given for prolonged periods; however, the Fischer 344 and Wistar rats appear to be more sensitive, and substantial new information should be forthcoming. In this review, some of the evidence for the possible mechanisms of papillary necrosis are presented: prostaglandin inhibition, reduction or redistribution of renal blood flow, direct cellular injury, free radical formation, and immunologic injury. At present, most data support prostaglandin inhibition and reduction or redistribution of renal blood flow, but direct cellular injury also appears to be very important.

Abstract
The pertinent literature concerning the experimental induction of analgesic nephropathy is reviewed. Based on the accumulated data from animal experiments that induced a pathologic lesion resembling chronic analgesic nephropathy, of the limited number of analgesics tested, aspirin seems to be the most nephrotoxic of the commonly available analgesics. When aspirin is combined with other analgesics, the limited data available suggest at least an additive nephrotoxic effect, if not a synergism. The histologic presentation of acute intoxication is substantially different from that following chronic ingestion. With improvements in pathologic analysis of experimental results, future studies may well provide more insight as to the significance, relative contribution, and risk of combination analgesic products in inducing experimental analgesic nephrotoxicity.
