Analgesic use and the risk of renal cell carcinoma - Findings from the Consortium for the Investigation of Renal Malignancies (CONFIRM) study. Cancer Epidemiol 2021; 75:102036. [PMID: 34562747 DOI: 10.1016/j.canep.2021.102036] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2021] [Revised: 09/10/2021] [Accepted: 09/11/2021] [Indexed: 12/31/2022]
Abstract
PURPOSE The incidence of renal cell carcinoma (RCC) is rising. Use of analgesics such as non-steroidal anti-inflammatory drugs (NSAIDs) and paracetamol may affect renal function. The aim of this study was to assess associations between analgesic use and risk of RCC. METHODS A population-based case-control family design was used. Cases were recruited via two Australian state cancer registries. Controls were siblings or partners of cases. Analgesic use was captured by self-completed questionnaire. Logistic regression was used to estimate odds ratios (OR) and 95% confidence intervals (CI) for RCC risk associated with regular analgesic use (at least 5 times per month for 6 months or more) and duration and frequency of use. RESULTS The analysis included 1064 cases and 724 controls. Regular use of paracetamol was associated with an increased risk of RCC (OR 1.41, 95%CI 1.13-1.77). Regular use of NSAIDs was associated with increased risk of RCC for women (OR 1.71, 95% CI 1.23-2.39) but not men (OR 0.83, 95% CI 0.58-1.18; p-interaction=0.003). There was no evidence of a dose-response for duration of use of paracetamol (linear trend p = 0.77) and weak evidence for non- aspirin NSAID use by women (linear trend p = 0.054). CONCLUSION This study found that regular use of paracetamol was associated with increased risk of RCC. NSAID use was associated with increased risk only for women.

Abstract
The metabolic consequences of xenobiotic-induced toxicity were investigated using high-resolution magic angle spinning (MAS) NMR spectroscopy of intact tissue. Renal papillary necrosis (RPN) was induced in Sprague-Dawley rats (n = 12) via a single i.p. dose of 250 mg/kg 2-bromoethanamine (BEA) hydrobromide. At 2, 4, 6, and 24 h after treatment with BEA, three animals were killed and tissue samples were obtained from liver, renal cortex, and renal medulla. Tissue samples were also removed at 2 and 24 h from matched controls (n = 6). (1)H MAS NMR spectroscopic techniques were used to analyze samples of intact tissue ( approximately 10 mg). Decreased levels of nonperturbing renal osmolytes (glycerophosphocholine, betaine, and myo-inositol) were observed in the renal papilla of BEA-treated animals at 6 and 24 h postdose (p.d.), concomitant with a relative increase in the tissue concentration of creatine. Increased levels of glutaric acid were found in all tissues studied in BEA-treated animals at 4 and 6 h p.d., indicating the inhibition of mitochondrial fatty acyl CoA dehydrogenases and mitochondrial dysfunction. Increased levels of trimethylamine-N-oxide occurred in the renal cortex at 6 h p.d. Changes in the metabolite profile of liver included an increase in the relative concentrations of triglycerides, lysine, and leucine. The novel application of (1)H MAS NMR to the biochemical analysis of intact tissues following a toxic insult highlights the potential of this technique as a toxicological probe in providing a direct link between urinary biomarkers of toxicity and histopathological evaluation of toxicological lesions.

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
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
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
The renal papillary toxin, propyleneimine (PI), was administered at 20 or 30 microliters/kg i.p. to male Sprague Dawley (SD) rats (n = 5), Fischer 344 (F344) rats (n = 4), and to multimammate desert mice (Mastomys natalensis, n = 4). Urine was collected at time points up to 4 days p.d. and the toxicological response of the different animal models to PI compared using 1H NMR spectroscopy of urine, renal histopathology, and urinary assays for alkaline phosphatase (ALP), lactate dehydrogenase (LDH), and gamma-glutamyl transpeptidase (gamma GT). The renal papillae of both F344 and SD rats showed extensive necrotic lesions 4 days post-dosing and in some cases sloughing of the papilla. However, only slight renal papillary necrosis (RPN) was observed in Mastomys treated with 20 microliters/kg PI and, although slight to moderate damage was observed at 30 microliters/kg, PI-treated Mastomys showed substantially less RPN than either group of PI-treated rats. 1H NMR urinalysis showed that PI treatment caused a decrease in the urinary concentrations of succinate (0-24 hr p.d.) and citrate (24-48 hr p.d.) and an increase in creatine (0-48 hr p.d.) in all animal models. Trimethylamine-N-oxide (24-48 hr) and 2-oxoglutarate concentrations decreased initially following the administration of PI and then rose above control levels. The 1H NMR-detected urinary biochemical effects of PI in all three models were similar. However, taurine concentrations were elevated in the urine of Mastomys following PI treatment, perhaps indicating a degree of liver damage, whereas taurinuria was not seen in either SD or F344 rats. These observations are discussed in relation to the potential mechanism of PI-toxicity.

Abstract
Patients with end-stage renal failure due to analgesic nephropathy have an increased risk of developing a urothelial carcinoma. To determine the impact of renal transplantation on the frequency of urothelial carcinomas, we analyzed 2072 patients who underwent 2371 renal transplantation between 1968 and 1993, including 78 (3.8%) with clinically proven analgesic nephropathy. Before and after transplantation a regular tumor screening was performed in patients with analgesic nephropathy by urine cytology and abdominal sonography. In 11 of the 78 patients with analgesic nephropathy (14.1%; age 51-66 years, 40-108 months after initiation of dialysis treatment, 5-77 months after transplantation), a urothelial carcinoma of the native urinary tract, especially the kidneys, was diagnosed. Therapy comprised nephroureterectomy (n = 6), transurethral resection (n = 6) and/or cystectomy (n = 2). Seven patients died due to tumor progression 16.3 (4-33) months postoperatively and one patient died due to a perioperative complication. Despite regular tumor screening after transplantation, the diagnosis of a urothelial carcinoma was made very late, leading to a high tumor-related mortality. As a consequence, we suggest that a bilateral nephroureterectomy should be performed prophylactically in patients with proven analgesic nephropathy. In addition, a cystoscopy with lavage cytology testing of the bladder should be performed twice a year.

Abstract
The biochemical effects and comparative nephroxicity of mercury II chloride (HgCl2) dosed at 0.75 mg/kg i.p. was investigated in the Fisher 344 rat (F344) and Mastomys natalensis using high resolution 1H nuclear magnetic resonance (NMR) spectroscopy of urine, histopathology and clinical chemical techniques. The effects of HgCl2 treatment were followed for up to 4 days post-dosing (p.d.). In F344 rats there was extensive proximal tubular damage and renal cortical necrosis together with elevated levels of urinary gamma-glutamyl transpeptidase (gamma GT), alkaline phosphatase (ALP) and lactate dehydrogenase (LDH). The 1H NMR spectra of urine obtained from Hg-treated F344 rats also showed increased levels of glucose, alanine, lactate, valine and hippurate (0-48h p.d.) with decreased levels of citrate, succinate and 2-oxoglutarate (24-48h p.d.). Mastomys were found to be highly resistant to HgCl2 toxicity at 0.75 mg/kg and the histological appearance of the renal cortex of treated animals was virtually identical to controls. There were no elevations in urinary ALP, gamma GT and LDH activities in HgCl2-treated Mastomys and there were no biochemical abnormalities in low MW components of Mastomys urine following HgCl2-treatment, as shown by 1H NMR spectroscopy. Urinary gamma GT activity was found to be much higher in F344 rats than Mastomys. Since gamma GT activity is involved in the tubular reabsorption of Hg2+, the lower levels of gamma GT in Mastomys might partially account for the lower toxicity of Hg2+ in this species.

Abstract
Renal papillary necrosis (RPN) was induced in Fischer 344 (F344) rats (n = 4) using 2-bromoethanamine hydrobromide (BEA) dosed at 150 mg/kg, and in multimammate desert mice (Mastomys natalensis) at 150 and 250 mg/kg (n = 4 per group). Control rats and Mastomys were dosed with 0.9% saline (n = 4 per group). Urine was collected at regular intervals for up to 4 days post-dosing and analysed for low MW metabolites using high resolution 1H NMR spectroscopy. The urinary activity of lactate dehydrogenase, gamma-glutamyl transpeptidase and alkaline phosphatase was determined using conventional biochemical assays. On termination, histopathological examination of papillae was performed showing the development of extensive lesions in F344 rats at 150 mg/kg BEA. Mastomys appeared much more resistant to BEA and showed normal renal histology at 150 mg/kg and patchy lesions at 250 mg/kg BEA. Enzyme analysis of control urine showed F344 rats to have > 1000% higher gamma-glutamyl transpeptidase activity than Mastomys. 1H NMR spectroscopic analysis showed that BEA caused a substantial decrease in urinary concentrations of succinate and citrate (0-24 h p.d.) and an increase in creatine (0-96 h p.d.) in both animal models. A decrease in the urinary concentration of 2-oxoglutarate with a subsequent increase by 72-96 h p.d. was also noted in both animal models. Glutaric and adipic aciduria were also induced in both F344 rats and Mastomys 0-24 h post-BEA treatment, indicative of an enzyme deficiency in the acyl CoA dehydrogenases. Urinary taurine levels were elevated in Mastomys following the administration of BEA, indicating some degree of liver toxicity. Urinary taurine was not elevated in F344 rats following BEA administration, demonstrating further species difference in BEA toxicity.

Abstract
Male Fischer 344 rats were dosed with 2-bromoethanamine hydrobromide (BEA, N = 6) or [1,2,2,-2H4]-bromoethanamine hydrobromide (BEA-d4, N = 6) at 150 mg/kg i.p. and urine was collected -24 to 0 hr pre-dose and at 0-2 hr, 2-4 hr, 4-8 hr and 8-12 hr post-dose (p.d.). Urine samples were analysed directly using 500 and 600 MHz 1H NMR and 92.1 MHz 2H NMR spectroscopy. The major observed effect of BEA treatment was the induction of transient elevations in urinary glutaric acid (GTA) and adipic acid (ADA) excretion lasting up to 24 hr p.d. Most of the GTA was excreted in the 0-8 hr p.d. with maximal rates of 100-120 microM/hr for each rat occurring between 4 and 8 hr p.d. in animals treated with BEA or BEA-d4. GTA and ADA were shown to be of endogenous origin as there was no detectable incorporation of the 2H label into either compound following treatment of rats with BEA-d4. Following BEA-treatment there was an initial decrease in the levels of urinary citrate, succinate, 2-oxoglutarate and trimethylamine-N-oxide. A subsequent recovery of citrate and succinate was noted following the onset of medullary nephropathy. The abnormal urinary metabolite profiles were similar to that observed in the urine of humans with glutaric aciduria type II (an inborn error of metabolism) caused by a lack of mitochondrial fatty acyl coenzyme A dehydrogenases indicating that BEA or its metabolites have similar metabolic consequences. The BEA metabolite aziridine was detected by 1H and 2H NMR spectroscopy of the urine 8 hr p.d. together with BEA itself and two novel metabolites 2-oxazolidone (OX) and 5-hydroxy-2-oxazolidone (HOX). The formation of OX requires the reaction of BEA with endogenous bicarbonate followed by a cyclisation reaction eliminating HBr. Dosing rats with authentic OX resulted in the excretion of HOX but did not cause glutaric or adipic aciduria indicating that either aziridine or BEA itself was responsible for the presumed defect in mitochondrial metabolism.

Abstract
1. The present study was designed to investigate the effects of acetylsalicylic acid and paracetamol given separately and in combination on total body and renal PGE2 synthesis in healthy volunteers. 2. In a randomized four-way cross-over study eleven female volunteers received for two consecutive days 3 g day-1 acetylsalicylic acid or 3 g day-1 paracetamol or a combination of 1.5 g day-1 acetylsalicylic acid and 1.5 g day-1 paracetamol, or 1.5 g day-1 acetylsalicylic acid separated by washout phases of at least 5 days. Urinary excretion of the major urinary metabolite of PGE2 (PGE-MUM), PGE2 and creatinine clearance were measured before and on day 2 of each treatment period. Compliance was tested by measuring metabolites of the two drugs in urine. 3. Paracetamol did not reduce urinary excretion of PGE2 whereas both dosages of acetylsalicylic acid caused a significant reduction. 4. The combination of both drugs did not reduce PGE2 excretion more than acetylsalicylic acid alone. 5. All four drug schedules reduced urinary excretion of PGE-MUM significantly.

Abstract
In a retrospective study, patients with end-stage renal failure from analgesic-associated nephropathy - 55 on regular dialysis treatment and 12 after renal transplantation - were under observation for 57 and 33 months, respectively. Of these 34 patients on chronic hemodialysis had suffered from different cardiovascular diseases. Hypertriglyceridemia was diagnosed in 62% of the patients, arterial hypertension requiring antihypertensive therapy in 44%. In three patients (5%) carcinoma of the urinary bladder were diagnosed. The leading causes of death in 21 patients included cardiovascular diseases (29%), hyperkalemia (19%), sepsis, and malignant tumors (14% each). Rejection occurred in 3 out of 12 patients after renal transplantation. Again, cardiovascular morbidity was high (58%) with coronary heart disease being present in 33% of the patients. Hypertriglyceridemia was observed in 5 out of 6 patients, antihypertensive therapy was needed in 50%. One patient died from primary pulmonary hypertension.

The effects of a 7 day-treatment with isoxicam (200 mg/24 h) on the urinary excretion of prostaglandins (PG) were compared to those of indomethacin (150 mg/24 h) in a double-blind randomized study conducted in 18 patients with degenerative arthritic disease and normal renal function. Indomethacin decreased the urinary excretion of PGF2 alpha by about 70% and 6-keto-PGF1 alpha and thromboxane (Tx)B2, the stable break-down products of prostacyclin and TxA2 respectively, by about 40%. Isoxicam effects on urinary PG did not significantly differ from those of indomethacin. During both treatments, urinary gamma-glutamyl transferase and N- acetyl-glucosaminidase remained stable and none of the changes in the urinary excretion of PGs could be related to either plasma or urinary drug concentrations. In conclusion, chronic administration of isoxicam inhibited the renal PG biosynthesis to a similar extent than indomethacin which suggests that non steroidal anti-inflammatory drugs of the oxicam group ought also be used cautiously in patients with renal impairment.

Abstract
An association between transitional cell tumors (TCT) and abuse of compound analgesics has been established during the past two decades. Recently thickening of basement membranes around subepithelial capillaries, known as capillarosclerosis, has been reported as a change in the urinary tract pathognomonic for a long-standing abuse of compound analgesics. Therefore the authors reviewed pathologic and clinical data in 59 patients treated for TCT of the renal pelvis or ureter. Capillarosclerosis was found in nine cases (15%) of the TCT group but not in any of the cases selected as controls. Capillarosclerosis is suggested as a valuable marker, which always should be looked for in bladder biopsy specimens. Whenever present it should arouse suspicion of analgesic abuse, and the associated increased risk for developing TCT of the renal pelvis or ureter should be borne in mind.
