Vinblastine and sulfinpyrazone export by the multidrug resistance protein MRP2 is associated with glutathione export. (1/40)

The multidrug resistance proteins MRP1 and MRP2 are members of the same subfamily of ATP-binding cassette transporters. Besides organic molecules conjugated to negatively charged ligands, these proteins also transport cytotoxic drugs for which no negatively charged conjugates are known to exist. In polarized MDCKII cells, MRP1 routes to the lateral plasma membrane, and MRP2 to the apical plasma membrane. In these cells MRP1 transports daunorubicin, and MRP2 vinblastine; both transporters export reduced glutathione (GSH) into the medium. We demonstrate that glutathione transport in MDCKII-MRP1 cells is inhibited by the inhibitors of organic anion transporters sulfinpyrazone, indomethacin, probenecid and benzbromarone. In MDCKII-MRP2 cells, GSH export is stimulated by low concentrations of sulfinpyrazone or indomethacin, whereas export is inhibited down to control levels at high concentrations. We find that unmodified sulfinpyrazone is a substrate for MRP2, also at concentrations where GSH export is inhibited. We also show that GSH export in MDCKII-MRP2 cells increases in the presence of vinblastine, and that the stoichiometry between drug and GSH exported is between two and three. Our data indicate that transport of sulfinpyrazone and vinblastine is associated with GSH export. However, at high sulfinpyrazone concentrations this compound is transported without GSH. Models of MRP action are discussed that could explain these results.  (+info)

Effect of urate-lowering therapy on the velocity of size reduction of tophi in chronic gout. (2/40)

OBJECTIVE: The optimal serum urate levels necessary for elimination of tissue deposits of monosodium urate in patients with chronic gout is controversial. This observational, prospective study evaluates the relationship between serum urate levels during therapy and the velocity of reduction of tophi in patients with chronic tophaceous gout. METHOD: Sixty-three patients with crystal-confirmed tophaceous gout were treated with allopurinol, benzbromarone, or combined therapy to achieve serum uric acid levels less than the threshold for saturation of urate in tissues. The tophi targeted for evaluation during followup were the largest in diameter found during physical examination. RESULTS: Patients taking benzbromarone alone or combined allopurinol and benzbromarone therapy achieved faster velocity of reduction of tophi than patients taking allopurinol alone. The velocity of tophi reduction was linearly related to the mean serum urate level during therapy. The lower the serum urate levels, the faster the velocity of tophi reduction. CONCLUSION: Serum urate levels should be lowered enough to promote dissolution of urate deposits in patients with tophaceous gout. Allopurinol and benzbromarone are equally effective when optimal serum urate levels are achieved during therapy. Combined therapy may be useful in patients who do not show enough reduction in serum urate levels with single-drug therapy.  (+info)

Effects of aspirin and/or salicylate on hydrolysis and glucuronidation of indomethacin in rat erythrocytes and hepatocytes. (3/40)

This study was conducted to explore the mechanism of the pharmacokinetic interaction between aspirin (ASP) and indomethacin (IND) using rat erythrocytes (RBCs) and hepatocytes. ASP was hydrolyzed to salicylic acid (SA) in both the RBCs and hepatocytes. Within RBCs, aspirin and/or salicylate (ASP/SA) increased the concentration of IND, accompanied by a constant hydrolysis of IND. In hepatocytes, a low dose of IND was subjected to glucuronidation rather than hydrolysis, and ASP/SA inhibited both the acylglucuronidation of IND and hydrolysis of IND glucuronide. A high dose of IND underwent hydrolysis with about double the glucuronidation, and ASP/SA decreased the ratio of hydrolysis to glucuronidation, accompanied by a loss of ASP, IND and their metabolites from the medium. Collectively, the results provide metabolic insight into the mechanism of drug-drug interaction between ASP/SA and IND in the hepatocytes and RBCs.  (+info)

A new class of CYP2C9 inhibitors: probing 2C9 specificity with high-affinity benzbromarone derivatives. (4/40)

Noncovalent forces, other than hydrophobic interactions, are important determinants of substrate bias exhibited by some cytochromes P450. The CYP2C9 pharmacophore is proposed to include either an anionic group or hydrogen bond donor in addition to its hydrophobic groups. By constructing analogs of benzbromarone, evidence supporting the existence of a 2C9 anion-binding site was revealed. A nonsubstituted phenol analog was determined to have a pKa of 8.4 and a Ki of 414 nM whereas those with dihalogenated benzoyl phenols had pKa values between 4.2 to 5.2 and Ki values as low as 1 nM. The nonhalogenated, nonionizable analog is the poorest binder at 796 nM. The Ki range covers around three orders of magnitude with even the weakest binder being a more potent inhibitor than 2C9 substrate phenytoin. Thus, benzbromarone derivatives represent a class of molecules with the potential to reveal more structural details of the 2C9 active site.  (+info)

A case of exercise-induced acute renal failure in a patient with idiopathic renal hypouricemia developed during antihypertensive therapy with losartan and trichlormethiazide. (5/40)

Exercise-induced acute renal failure (ARF) developed in a 45-year-old man during antihypertensive therapy with losartan and trichlormethiazide. The antihypertensive therapy was stopped and marked hypouricemia became apparent during improvement of his renal function. The daily urinary excretion of uric acid was normal and an increased fractional excretion of uric acid was observed. Renal biopsy revealed that the kidney was recovering from acute tubular necrosis with interstitial fibrosis. Based on the results of pyrazinamide and benzbromarone tests, we classified this case as one of presecretory reabsorption defect of uric acid. Antihypertesive therapy with benidipine and candesartan was initiated, and the patient has not had any ARF episodes since. Because idiopathic renal hypouricemia can be associated with exercise-induced ARF and chronic renal dysfunction, careful antihypertensive therapy and follow-up evaluation of renal function might be necessary for hypertensive patients with idiopathic renal hypouricemia.  (+info)

Circadian rhythm of plasma uric acid and handling stress-induced hyperuricemia in conscious cebus monkeys. (6/40)

An apparent circadian rhythm of plasma uric acid and the effect of handling stress on plasma uric acid level in conscious cebus monkeys were demonstrated. The lowest level of plasma uric acid in the circadian rhythm occurred early in the morning and the highest, before bedtime at night. With experimental handling stress, the plasma uric acid level rose to much more than the maximum level of the circadian rhythm. Stress-induced hyperuricemia could be inhibited without an increase of urinary uric acid excretion by the minor tranquilizer diazepam at doses of more than 1 mg/kg, p.o. On the other hand, benzbromarone at 20 mg/kg, p.o. significantly inhibited the hyperuricemia with a hyperuricosuric effect, while probenecid at 50 mg/kg, p.o. had no effect on either the increased plasma uric acid or urinary uric acid excretion. Accordingly, it is concluded that the plasma uric acid level in conscious cebus monkeys easily fluctuates with experimental conditions and that the animals can be utilized to evaluate the hypouricemic and hyperuricosuric property of benzbromarone-like agents.  (+info)

CYP2C9 genotype-dependent effects on in vitro drug-drug interactions: switching of benzbromarone effect from inhibition to activation in the CYP2C9.3 variant. (7/40)

The CYP2C9.3 variant exhibits marked decreases in substrate turnover compared with the wild-type enzyme, but little is known regarding the effect this variant form may have on the occurrence of drug-drug interactions. To examine this possibility, the effect of the potent CYP2C9 inhibitor, benzbromarone, was studied with regard to CYP2C9.1- and CYP2C9.3-mediated flurbiprofen metabolism to evaluate whether the variant enzyme exhibits differential inhibition kinetics. Although benzbromarone inhibited CYP2C9.1 activity as expected, CYP2C9.3-mediated flurbiprofen 4'-hydroxylation was activated in the presence of benzbromarone. T1 relaxation studies revealed little change in distances of flurbiprofen protons from the heme iron of either CYP2C9.1 or CYP2C9.3 in the presence of benzbromarone compared with flurbiprofen alone. Spectral binding studies were also performed to investigate whether benzbromarone affected substrate binding, with the addition of benzbromarone having little effect on flurbiprofen-binding affinity in both CYP2C9.1 and CYP2C9.3. Docking studies with the 2C9.1 structure crystallized with a closed active site identified multiple but overlapping subsites with sufficient space for benzbromarone binding in the enzyme when flurbiprofen was positioned closest to the heme. If the closed conformation of 2C9.3 is structurally similar to 2C9.1, as expected for the conservative I359L mutation, then the dynamics of benzbromarone binding may account for the switching of drug interaction effects. In conclusion, the I359L amino acid substitution found in CYP2C9.3 not only reduces metabolism compared with CYP2C9.1 but can also dramatically alter inhibitor effects, suggesting that differential degrees of drug inhibition interactions may occur in individuals with this variant form of CYP2C9.  (+info)

Prediction of CYP2C9-mediated drug-drug interactions: a comparison using data from recombinant enzymes and human hepatocytes. (8/40)

The IC50 values of 14 drugs were determined in recombinantly expressed CYP2C9 (rCYP2C9) and human hepatocytes and the data used to simulate clinical area under the plasma concentration-time curve (AUC) changes upon coadministration with prototypic CYP2C9 substrates. There was an excellent correlation between IC(50, apparent) values determined using diclofenac and naproxen as CYP2C9 substrates (r2 = 0.82, p < 0.0001), with values being generally higher in the naproxen assay. After correcting for nonspecific binding, the IC(50, unbound) values were similar between the assays, for the majority of compounds. Two compounds, amiodarone and benzbromarone, demonstrated substrate-specific differences, activating naproxen O-demethylase to approximately 250% of control activity at 1 mM and 1 microM, respectively, while inhibiting diclofenac 4'-hydroxylation with IC(50, apparent) values of 3 microM and 0.04 microM, respectively. CYP2C9 IC(50, apparent) values generated in human hepatocytes were systematically higher than those determined with rCYP2C9. After correcting for nonspecific binding, there was an excellent correlation of IC(50, unbound) values generated in the different milieu (r2 = 0.88, p < 0.0001). The ratio of inhibitor concentration at the entrance to the liver to the inhibition constant ([I]in/Ki) was used to simulate clinical deltaAUC changes and compared with that observed in vivo. Where [I]in, total/Ki, apparent) was used, there were zero false negatives (observed deltaAUC >or=2, predicted deltaAUC <2), eight correct assignations, and seven false positives (observed deltaAUC 2. Where [I]in, unbound/Ki, unbound was used, there was one false negative, 14 correct assignations, and zero false positives. In summary, the data presented here suggest that for CYP2C9 interactions, the use of total liver inhibitor concentrations may indeed avoid false negatives, but more realistic predictions may be achieved using unbound liver inhibitor concentrations and unbound in vitro inhibition parameters.  (+info)

Benzbromarone is a uricosuric agent and non-competitive inhibitor of xanthine oxidase used in the treatment of gout, especially when allopurinol, a first-line treatment, fails or produces intolerable adverse effects. It is structurally related to the antiarrhythmic amiodarone. Benzbromarone is highly effective and well tolerated, and clinical trials as early as 1981 and as recently as April 2008 have suggested it is superior to both allopurinol, a xanthine oxidase inhibitor but not uricosuric, and probenecid, another uricosuric drug.

This study shows that benzbromarone is very useful for the control of hyperuricaemia using doses ranging from 50 to 100 mg/day. It also shows that 47% of our patients taking allopurinol did not achieve optimal Pur concentrations with 300 mg/day despite alcohol abstinence and weight reduction. Previous studies showed that poor control of uricaemia is common,23-27 and it may result in radiological progression of bony lesions,23 increased size of tophi,23 and frequent recurrence of gouty bouts and tophi after withdrawal of urate lowering treatment.24 25 27 Although most standard sources of information recommend uricosurics to correct hyperuricaemia in underexcretors,5-8 29 30this approach is not a common practice in more recent studies.23-26 Epidemiological studies show that only 2-15% of patients with gout were taking uricosuric drugs.30-32 It may be because uricosurics such as probenecid or sulphinpyrazone have to be given in a twice daily regimen and have little efficacy in patients with low ...

In the present study we identified a novel compound, UR-1102, as a potent URAT1 inhibitor that is selective over OAT1 and OAT3. In the monkey model, UR-1102 showed a better PK profile and reduced the levels of urate in plasma to a greater extent through its stronger uricosuric effect compared with benzbromarone, even when the plasma exposures were comparable, and achieved a maximum efficacy twice that of benzbromarone at a lower dose. Additionally, UR-1102 showed lower in vitro toxic potential in every mechanism that has been proposed for the hepatic toxicity of benzbromarone.. OAT1 and OAT3 are nonspecific anion transporters reported to be involved in urate excretion. Because they are both expressed in the basolateral membrane of renal proximal tubules and transport urate from the blood to inside the cells (Bakhiya et al., 2003; Ichida et al., 2003; Choi et al., 2005), inhibiting these transporters would decrease the secretion of urate into the urine. As mentioned earlier, the inability of ...

The new RAFT enables the production of reproducible 3D cell cultures in a standard 96-well plate format designed for compound screening and cell biology research. It uses collagen to create a realistic cellular environment to study complex cell behavior and gives scientists complete control over their experimental parameters.
Below is a procedure for adherent cells (ie A431, A549, Hela, NIH3T3) I) Remove culture medium and rinse a subconfluent, 100 mm cell culture plate (80% confluent plate yields ~600-1000 microg protein total) with PBS at room temperature. The following steps should be performed on ice or at 4° C using fresh, ice cold buffers. II) Add 0.8 ml of ice cold fresh RIPA buffer to the 100 mm cell culture plates OR 0.5 ml per 5 x 10e6 cells/60 mm dish. III) Gently rock plates for 15 minutes at 4° C or let the plates set on ice. This step will allow the lysis buffer to act on the cells and will increase the total yield of soluble protein. IV) For monolayer cells, do a trypsin treatment to lift cells off the flasks prior to cell lysis, instead of scraping the cells for a more gentle approach. OR Scrape the adherent cells with a cell scraper and then transfer the scraped lysate into a sterile microcentrifuge tube. Place the tube on ice. Optional: wash the plate once with 0.2 ml of RIPA buffer and combine ...

Do you use all wells of your 96 well plate including the outer ones? Usually, these wells are not used for a good reason: Increased evaporation in the outer wells reduces reproducibility and comparability between all wells (edge effect). Therefore, more than a third of a plate is not used. More experiments are necessary which mean higher costs. With Eppendorf Cell Culture Plates, the surrounding moat can be filled. This significantly reduces the edge effect and all wells become comparable. Learn more by reading our Application Notes 326 and 384. ...

Hyperuricemia in Dalmatians (as in all breeds) is inherited, but unlike other breeds, the "normal" gene for a uric acid transporter that allows for uric acid to enter liver cells and be subsequently broken down is not present in the breeds gene pool. Therefore, there is no possibility of eliminating hyperuricemia among pure-bred Dalmatians. The only possible solution to this problem must then be crossing Dalmatians with other breeds to reintroduce the "normal" uric acid transporter gene. This led to the foundation of the Dalmatian-Pointer Backcross Project, which aims to reintroduce the normal uric acid transporter gene into the Dalmatian breed. The backcross used a single English Pointer; subsequent breedings have all been to purebred Dalmatians. This project was started in 1973 by Dr. Robert Schaible. The first cross (F1) hybrids did not resemble Dalmatians very closely. The F1s were then crossed back to purebreds. This breeding produced puppies of closer resemblance to the pure Dalmatian. By ...

Background: what are tophi and what interventions are used? Gout is caused by urate crystals forming either within or around joints. Inflammation can lead to pain, redness, warmth and swelling of the affected joints, making the area difficult to touch or move. Some of the reasons why people get gout include their genetic make-up, being overweight, ingesting certain medications (e.g. cyclosporine), impaired kidney function and lifestyle habits such as drinking excessive amounts of alcohol and sugar-sweetened drinks. Tophi are nodules that develop in people with poorly treated or uncontrolled chronic gout. Tophi can become infected, cause pain and lead to a decrease in function. Tophi can be treated with urate-lowering drugs (e.g. benzbromarone, probenecid, allopurinol, febuxostat, pegloticase), surgical removal or other interventions such as haemodialysis. Surgical interventions can be used where urgent removal is required, for example, for relief of nerve compression.. Study characteristics This ...

N2 - Mutations in the ABCC6 (MRP6) gene cause pseudoxanthoma elasticum (PXE), a rare heritable disorder resulting in the calcification of elastic fibers. In the present study a cDNA encoding a full-length normal variant of ABCC6 was amplified from a human kidney cDNA library, and the protein was expressed in Sf9 insect cells. In isolated membranes ATP binding as well as ATP-dependent active transport by ABCC6 was demonstrated. We found that glutathione conjugates, including leukotriene C4 and N-ethylmaleimide S-glutathione (NEM-GS), were actively transported by human ABCC6. Organic anions (probenecid, benzbromarone, indomethacin), known to interfere with glutathione conjugate ...

Ganoderma applanatum (G. applanatum) dispels wind to eliminate dampness and exhibited nephron- and liver-protective effects as noted in Chinese herbal classic literature; it might also affect hyperuricemia. Therefore, we examined the hypouricemia effects and mechanisms underlying G. applanatum on chemical-induced hyperuricemia in mice. Ethanol (GAE) and water (GAW) extracts were prepared by extracting G. applanatum in ethanol (GAE), followed by bathing the remains in water to yield GAW. GAE and GAW were administered orally at different doses to hyperuricemia mice, while allopurinol and benzbromarone served as positive controls. Both GAE and GAW showed remarkable hypouricemia activities, rendering a substantial decline in the SUA (serum uric acid) level in hyperuricemia control (P

The angiotensin II (AII) antagonist, losartan, increases uric acid excretion when administered to humans. However, the active metabolite of losartan, EXP 3174, and other nonpeptide AII antagonists such as eprosartan and SB 203220 are devoid of uricosuric activity. To investigate the mechanism of losartan-induced uricosuria, we examined the effects of losartan, EXP 3174, eprosartan and SB 203220 on OH- -dependent [14C]urate uptake into rat proximal tubule brush-border membrane vesicles. Losartan (10 microM) inhibited [14C]urate uptake at all time points examined, except at equilibrium (2 hr). Losartan had no effect on urate uptake in the absence of an OH- gradient. The inhibitory effect of losartan on urate uptake was concentration dependent (IC50 = 9.5 +/- 1.4 microM) and competitive in nature. The other AII antagonists also inhibited urate uptake but were 6-8-fold less potent than losartan with IC50 values of EXP 3174 (65 +/- 13 microM), eprosartan (60 +/- 7.0 microM) and SB 203220 (74 +/- 12.5 ...
Background & Rationale:. Convergent epidemiological and clinical observations have identified urate - a major antioxidant and the end product of purine metabolism in humans - as the first molecular predictor of both the risk and the progression of typical Parkinsons disease (PD). Among some 1600 early PD patients enrolled in prior clinical trials, those with baseline serum urate levels in the highest quintile (i.e., in the upper normal range) displayed a 40% slower rate of clinical (disability) progression compared to those with baseline urate at or below the median (with p,0.000001 for trend across quintiles). Similarly, amongst those who underwent serial SPECT brain scans for changes in dopamine transporter (DAT) binding, those with higher baseline serum urate levels displayed a slower rate of radiographic progression (loss of striatal DAT). Moreover, urate levels in baseline cerebrospinal fluid (CSF) samples also correlate inversely with rates of clinical progression. Although this link ...

Introduction Adherence to urate-lowering drugs (ULDs) has not been well evaluated among those with gout. Our aim was to assess the level and determinants of non-adherence with ULDs prescribed for gout.
RESULTS: Of 23,371,362 beneficiaries in 2010, there were 1,458,569 prevalent and 56,595 incident cases of gout, giving a prevalence of 6.24% (95% confidence interval (CI), 6.23% to 6.25%) and an incidence of 2.74 (95% CI, 2.72 to 2.76) per 1,000 person-years. The annual percentage change (APC) of the standardised prevalence was −0.7% (95% CI, −1.7% to 0.3%; P = 0.14), suggesting that the prevalence of gout was essentially the same throughout the study period. However, The APC of incidence was −13.4 (95% CI, −16.1 to −10.6) between 2005 and 2007 and −2.1 (95% CI, −10.4 to 7.1) between 2007 and 2010. Regions with the highest prevalence and incidence were eastern coastal counties and offshore islets, where indigenous people are clustered. Among prevalent gout cases in 2010, only 22.93% (95% CI, 22.87% to 23.00%) were prescribed urate-lowering treatment (ULT), which remained unchanged between 2005 and 2010 at an APC of 0.0 (95% CI, −3.8 to 4.0). Uricosuric agents were more commonly ...

Probenecid is a uricosuric and branch blocking agent. It inhibits the re-absorption of uric acerbic in the kidneys, appropriately accretion the elimination of uric acerbic in urine and abbreviating urate levels in the blood. This stops new crystals forming, and helps old clear deposits to deliquesce . It is a lot of advantageous to under-excreters…
Many factors, including genetic components and acquired factors such as obesity and alcohol consumption, influence serum uric acid (urate) concentrations. Since serum urate concentrations are determined by the balance between renal urate excretion and the volume of urate produced via purine metabolism, urate transporter genes as well as genes coding for enzymes involved in purine metabolism affect serum urate concentrations. URAT1 was the first transporter affecting serum urate concentrations to be identified. Using the characterization of this transporter as an indicator, several transporters have been shown to transport urate, allowing the construction of a synoptic renal urate transport model. Notable re-absorptive urate transporters are URAT1 at apical membranes and GLUT9 at basolateral membranes, while ABCG2, MRP4 (multidrug resistance protein 4) and NPT1 are secretive transporters at apical membranes. Recent genome-wide association studies have led to validation of the in vitro model constructed
Elevated serum urate concentrations can cause gout, a prevalent and painful inflammatory arthritis. By combining data from ,140,000 individuals of European ancestry within the Global Urate Genetics Consortium (GUGC), we identified and replicated 28 genome-wide significant loci in association with serum urate concentrations (18 new regions in or near TRIM46, INHBB, SFMBT1, TMEM171, VEGFA, BAZ1B, PRKAG2, STC1, HNF4G, A1CF, ATXN2, UBE2Q2, IGF1R, NFAT5, MAF, HLF, ACVR1B-ACVRL1 and B3GNT4). Associations for many of the loci were of similar magnitude in individuals of non-European ancestry. We further characterized these loci for associations with gout, transcript expression and the fractional excretion of urate. Network analyses implicate the inhibins-activins signaling pathways and glucose metabolism in systemic urate control. New candidate genes for serum urate concentration highlight the importance of metabolic control of urate production and excretion, which may have implications for the ...

In a double-blind multicenter study, 124 patients with transient ischemic attacks were randomly allocated to one of two groups treated with aspirin (ASA) or sulfinpyrazone respectively. Patients were followed up to assess the relative efficacy of the two treatments in the prevention of the outcomes of stroke, myocardial infarction, vascular death, and worsening or no improvement of TIAs. No significant difference was observed between the two treatments at the end of the follow-up period. Statistical analysis revealed a significant interaction of sex, treatment, and occurrence of events. Analysis of the results according to sex showed that male patients treated with ASA had a highly significant benefit (p less than 0.001) with a 53% risk reduction for further events. In female patients, sulfinpyrazone showed a favorable trend which was not statistically significant. ...

If your gout is severe, prolonged, or chronic, you may need to take daily serum uric acid-lowering (SUA) medication to reduce your uric acid levels. Your doctor will put you on the lowest dose possible of medications such as uricosuric drugs or xanthine oxidase inhibitors. Doctors usually prescribe allopurinol (Zyloprim, a xanthine oxidase inhibitor) for patients who overproduce urates or have tophi, kidney disease, or kidney stones. Allopurinol is useful in preventing recurrence of gouty attacks. It blocks the production of uric acid and decreases the formation of purine. For patients who have difficulty getting rid of uric acid through the kidneys, medications to help the kidneys remove more uric acid from the blood may be prescribed as well. Probenecid is one of the commonly prescribed drugs that increase the removal of uric acid in the urine.. Another, serum uric acid-lowering (SUA) medications that has been shown to reduce the risk of occurrence is Uloric (Febuxostat). Febuxostat has been ...

1. The effect on urate excretion of administration of probenecid and pyrazinamide was observed in normal subjects under control conditions and after induction of uricosuria by exogenous urate loading by ribonucleic acid feeding in seven subjects, by volume loading with hypertonic sodium chloride solution infusion in 11 subjects and by partial inhibition of net urate reabsorption with uricosuric drugs in 20 subjects.. 2. After ribonucleic acid feeding, the uricosuric response to probenecid was intact and ribonucleic acid feeding did not produce uricosuria after pyrazinamide.. 3. After volume loading, the uricosuric response to probenecid was again intact, but infusion of sodium chloride solution still produced uricosuria after pyrazinamide administration.. 4. After uricosuric drugs, the uricosuric response to probenecid was diminished.. 5. These responses to probenecid and pyrazinamide may reflect different mechanisms of uricosuria. Response to pharmacological inhibitors of urate reabsorption or ...
Gout is a common and complex form of arthritis that is characterized with hyperuricaemia. It is required urate-lowering therapy (ULT) for lifelong management. ULT includes decreasing uric acid product in serum, increasing renal urate excretion and promoting uric acid to allantoin for excretion. Whole genome association studies in gout identified more than 40 genetic loci that influenced the serum uric acid levels. Most associated genes were found to affect renal urate excretion. Pharmacogenetics and pharmacogenomics approaches on ULT had revealed several genes that underlined the effectiveness and the adverse events of medications for gout. Together with the researches on epigenetic factors such as DNA methylations, miRNAs; and the discovery of environmental factors such as microbiota and metabolites, the current progress provides the opportunities for personalized management of ULT for treating hyperuricaemia and gout.
Author summary Why was this study done? Epidemiological studies have shown strong correlations between serum urate (SU) levels and chronic kidney disease (CKD) risk. Elevated SU levels are often found in patients with CKD, but it is not clear whether high serum urate is a cause of kidney disease or just a common co-occurrence. Previous studies examining whether SU levels had a causal effect on CKD were limited due to not having large enough samples to detect a true causal relationship if it existed and/or had limitations related to the methodology. Several clinical trials have been started that aim to use urate-lowering medication to prevent CKD. What did the authors do and find? To determine whether SU level has a causal effect on CKD, we used a methodology known as Mendelian randomization to test whether genetic variants known to increase SU level also increased the risk of CKD. We used multiple datasets to perform Mendelian randomization analyses, which included meta-analyses performed across
INTRODUCTION: Gout is characterized by recurrent episodes of acute inflammation of joint structures, called gout flares, and flares are commonly treated with nonsteroidal anti-inflammatory drugs (NSAIDs). The objective of the study was to evaluate risk factors associated with acute kidney injury (AKI) attributed to NSAIDs in a cohort of patients who were exposed to NSAIDs to treat gout flares prior to urate-lowering therapy. METHODS: Retrospective analysis of a nested cohort of 983 gout patients in whom general variables (age, gender, renal function, ethanol intake, hypertension, hyperlipidemia, diabetes, vascular events, diuretic use) and also variables related to gout and severity of gout (serum urate levels, number for flares per year, presence of tophi, joint distribution, X-ray involvement, previous urate-lowering therapy) were available for analysis ...
BACKGROUND: Little is known about the characteristics, evaluation and treatment of women with gout. OBJECTIVE: To examine the epidemiological differences and differences in treatment between men and women in a large patient population. METHODS: The data from approximately 1.4 million people who were members of seven managed care plans in the USA for at least 1 year between 1 January 1999 and 31 December 2003 were examined. Adult members who had pharmacy benefits and at least two ambulatory claims specifying a diagnosis of gout were identified. In addition, men and women who were new users of urate-lowering drugs (ULDs) were identified to assess adherence with recommended surveillance of serum urate levels within 6 months of initiating urate-lowering treatment. RESULTS: A total of 6133 people (4975 men and 1158 women) with two or more International Classification of Disease-9 codes for gout were identified. As compared with men with gout, women were older (mean age 70 (SD 13) v 58 (SD 14), p|0.001) and

Gout is an ancient disease which dates back to the time of Babylon. Its name comes from the Latin word gutta, (meaning drop), which reflect an old belief that the disease is caused by a poison which fall into the joint drop by drop. The disease is quite prevalent nowadays and is considered as the most common inflammatory type of arthritis in men affecting 1-2% of adults in Western countries, with male to female ratio of 3.6:1. It is rare in pre-menopausal women and its incidence and prevalence increases with age. Gout is an inflammatory syndrome caused as a response to monosodium urate monohydrate crystals (MSUM) formed in humans in the presence of having elevated serum urate concentration what is known as hyperuricemia. Hyperuricemia is defined as serum urate levels above 6.8mg/dl (≥ 400µmol/L) which is the level above which the physiological saturation threshold is exceeded.. ...
Gout sufferers experience a great disruption of their usual activities of daily living during attacks. Intense pain, along with severe articular and periarticular swelling will be two of the most devastating sign and symptom that gout can impose to be able to anyone suffering from that. Gout is brought on by excess numbers of uric acid in the bloodstream or scientifically dubbed as hyperuricemia. We can say that a person has hyperuricemia when his/her laboratory results read as uric acid level of more than 6mg/dL or 0.35 mmol/L. There are a number of approved and proven pharmacologic treatments for gout in the market nowadays. There are those that inhibit the production of uric acid whilst some aid in excreting the excess uric acid thereby attaining the common objective of gout treatment, which is to reduce the uric acid levels in the body ...
XORTX is developing oxypurinol, a uric acid lowering agent.

Blood loss can also be caused by internal bleeding, usually in the digestive tract. A stomach ulcer, ulcerative colitis, cancer, or taking anti-inflammatory pills such as Ibuprofen or Aspirin for a long time can cause bleeding in your stomach or intestines. Thats why its so important to find the reason for a low iron level. Inability to absorb iron: Diseases that affect your small intestines ability to absorb nutrients can lead to anemia. Some foods or medicines, including milk or stomach acid-lowering medicines, can also prevent your body from absorbing iron.. ...

A tophus (Latin: "stone", plural tophi) is a deposit of monosodium urate crystals, in people with longstanding high levels of uric acid in the blood, a condition known as hyperuricemia. Tophi are pathognomonic for the disease gout. Most people with tophi have had previous attacks of acute arthritis, eventually leading to the formation of tophi. Chronic tophaceous gout is known as Harrison Syndrome. Tophi form in the joints, cartilage, bones, and other places throughout the body. Sometimes, tophi break through the skin and appear as white or yellowish-white, chalky nodules. Without treatment, tophi may develop on average about ten years after the onset of gout, although their first appearance can range from three to forty-two years. The development of gouty tophi can also limit joint function and cause bone destruction, leading to noticeable disabilities, especially when gout cannot successfully be treated.[1] When uric acid levels and gout symptoms cannot be controlled with standard gout ...
Uricosuric agents (eg, allopurinol) Alkalinizing agents (eg, potassium citrate, sodium bicarbonate): For uric acid and cysteine calculi Thiazide diuretics: Help treat hypercalcicuria
Colchicine is a uricosuric agent used in the treatment of several systemic and dermatologic conditions. Its medicinal value has been reported since the first century where it was extracted from the autumn crocus plant. The drug is rapidly absorbed, metabolized in the liver and excreted mainly in the feces. Initial effect can take anywhere between 12 to 24 hours with its peak anti-inflammatory effect occurring within 24 to 48 hours.. Mechanism: Since colchicine is used for both systemic and dermatologic disease, it has been shown to possess multiple different mechanisms. The medication is mostly used for its anti - inflammatory processes. Colchicine binds proteins in microtubules of neutrophils and prevents migration into areas of inflammation. It also prevents the release of inflammatory glycoprotein from phagocytes. Additionally, the medication inhibits leukocyte migration by interfering with inflammasome complex assembly in neutrophils and monocytes, preventing the activation of interleukin-1. ...

... R-250 was first used to visualise proteins in 1964 by Fazekas de St. Groth and colleagues. Protein samples were separated electrophoretically on a cellulose acetate sheet. The sheet was then soaked in sulfosalicylic acid to fix the protein bands and then transferred to a solution of the dye.[10] Two years later in 1965 Meyer and Lambert used Coomassie Brilliant Blue R-250 to stain protein samples after electrophoretic separation in a polyacrylamide gel. They soaked the gel in a dye solution containing methanol, acetic acid and water. As the dye stained the polyacrylamide gel as well as the protein, in order to visualise the protein bands they needed to destain the gel which they did electrophoretically.[11] Subsequent publications reported that polyacrylamide gels could be successfully destained using an acetic acid solution. The first report of the use of the "G" form of the dye to visualise protein bands in polyacrylamide gels came in 1967, where the dye was dissolved ...

... is a purine nucleoside comprising guanine attached to a ribose (ribofuranose) ring via a β-N9-glycosidic bond. Guanosine can be phosphorylated to become guanosine monophosphate (GMP), cyclic guanosine monophosphate (cGMP), guanosine diphosphate (GDP), and guanosine triphosphate (GTP). These forms play important roles in various biochemical processes such as synthesis of nucleic acids and proteins, photosynthesis, muscle contraction, and intracellular signal transduction (cGMP). When guanine is attached by its N9 nitrogen to the C1 carbon of a deoxyribose ring it is known as deoxyguanosine. The antiviral drug acyclovir, often used in herpes treatment, and the anti-HIV drug abacavir, are structurally similar to guanosine. Guanosine is required for an RNA splicing reaction in mRNA, when a "self-splicing" intron removes itself from the mRNA message by cutting at both ends, re-ligating, and leaving just the exons on either side to be translated into protein.[1] ...
... is not produced by plants[citation needed] and is only observed in nature as a metabolite of caffeine in animals. Paraxanthine is also a natural metabolite of caffeine in some species of bacteria.[1] After intake, roughly 84% of caffeine is demethylated at the 3-position to yield paraxanthine, making it the chief metabolite of caffeine in the body.[2] Paraxanthine is also a major metabolite of caffeine in humans and other animals, such as mice.[3] Shortly after ingestion, caffeine is metabolized into paraxanthine by hepatic cytochrome P450,[4] which removes a methyl group from the N3 position of caffeine.[5] After formation, paraxanthine can be broken down to 7-methylxanthine by demethylation of the N1 position,[6] which is subsequently demethylated into xanthine or oxidized by CYP2A6 and CYP1A2 into 1,7-dimethylaric acid.[5] In another pathway, paraxanthine is broken down into 5-acetylamino-6-formylamino-3-methyluracil through N-acetyl-transferase 2, which is then broken down into ...
... has been shown to inhibit TGF-beta-mediated conversion of pulmonary fibroblasts into myofibroblasts in COPD and asthma via cAMP-PKA pathway and suppresses COL1 mRNA, which codes for the protein collagen.[24] It has been shown that theophylline may reverse the clinical observations of steroid insensitivity in patients with COPD and asthmatics who are active smokers (a condition resulting in oxidative stress) via a distinctly separate mechanism. Theophylline in vitro can restore the reduced HDAC (histone deacetylase) activity that is induced by oxidative stress (i.e., in smokers), returning steroid responsiveness toward normal.[25] Furthermore, theophylline has been shown to directly activate HDAC2.[25] (Corticosteroids switch off the inflammatory response by blocking the expression of inflammatory mediators through deacetylation of histones, an effect mediated via histone deacetylase-2 (HDAC2). Once deacetylated, DNA is repackaged so that the promoter regions of inflammatory genes ...

ADP cycling supplies the energy needed to do work in a biological system, the thermodynamic process of transferring energy from one source to another. There are two types of energy: potential energy and kinetic energy. Potential energy can be thought of as stored energy, or usable energy that is available to do work. Kinetic energy is the energy of an object as a result of its motion. The significance of ATP is in its ability to store potential energy within the phosphate bonds. The energy stored between these bonds can then be transferred to do work. For example, the transfer of energy from ATP to the protein myosin causes a conformational change when connecting to actin during muscle contraction. It takes multiple reactions between myosin and actin to effectively produce one muscle contraction, and, therefore, the availability of large amounts of ATP is required to produce each muscle contraction. For this reason, biological processes have evolved to produce efficient ways to replenishment the ...
Animals that metabolize theobromine (found in chocolate) more slowly, such as dogs,[26] can succumb to theobromine poisoning from as little as 50 grams (1.8 oz) of milk chocolate for a smaller dog and 400 grams (14 oz), or around nine 44-gram (1.55 oz) small milk chocolate bars, for an average-sized dog. The concentration of theobromine in dark chocolates (approximately 10 g/kg (0.16 oz/lb)) is up to 10 times that of milk chocolate (1 to 5 g/kg (0.016 to 0.080 oz/lb)) - meaning dark chocolate is far more toxic to dogs per unit weight or volume than milk chocolate. The same risk is reported for cats as well,[27] although cats are less likely to ingest sweet food, with most cats having no sweet taste receptors.[28] Complications include digestive issues, dehydration, excitability, and a slow heart rate. Later stages of theobromine poisoning include epileptic-like seizures and death. If caught early on, theobromine poisoning is treatable.[29] Although not common, the effects of theobromine ...
Derivatives of xanthine (known collectively as xanthines) are a group of alkaloids commonly used for their effects as mild stimulants and as bronchodilators, notably in the treatment of asthma symptoms. In contrast to other, more potent stimulants like sympathomimetic amines, xanthines mainly act to oppose the actions of the sleepiness-inducing adenosine, and increase alertness in the central nervous system. They also stimulate the respiratory centre, and are used for treatment of infantile apnea. Due to widespread effects, the therapeutic range of xanthines is narrow, making them merely a second-line asthma treatment. The therapeutic level is 10-20 micrograms/mL blood; signs of toxicity include tremor, nausea, nervousness, and tachycardia/arrhythmia. Methylated xanthines (methylxanthines), which include caffeine, aminophylline, IBMX, paraxanthine, pentoxifylline,[9] theobromine, and theophylline, affect not only the airways but stimulate heart rate, force of contraction, and cardiac arrhythmias ...
... , also known as β-methylbutyric acid or more commonly isovaleric acid, is an organic compound with the formula (CH3)2CHCH2CO2H. It is sometimes classified as a fatty acid. It is a colourless liquid that is sparingly soluble in water, but highly soluble in most common organic solvents. The compound occurs naturally, including in essential oils. Isovaleric acid has a strong pungent cheesy or sweaty smell, but its volatile esters have pleasing scents and are used widely in perfumery. It has been proposed that it is the anticonvulsant agent in valerian.[1] It is a major component of the cause of unpleasant foot odor, as it is produced by skin bacteria metabolizing leucine.[2] Isovaleric acid is seen as the primary cause of the flavors added to wine caused by Brettanomyces yeasts.[3] Other compounds produced by Brettanomyces yeasts include 4-ethylphenol, 4-vinylphenol, and 4-ethylguaiacol.[4] An excess of isovaleric acid in wine is generally seen as a defect,[4] as it can smell ...
