Acute Gouty Arthritis (acute + gouty_arthritis)
Selected AbstractsReversible acute renal failure associated with hypothyroidism: Report of four cases with a brief review of literatureNEPHROLOGY, Issue 2 2003Ahmad MOORAKI SUMMARY: ,,We present four adult cases of acute renal failure associated with hypothyroidism. All patients presented with symptoms suggestive of moderate to severe hypothyroidism, such as cold intolerance, constipation, muscle weakness, and lower extremity oedema. Initial serum creatinine levels ranged between 115 and 203 µmol/L (1.3 and 2.3 mg/dL), with creatinine clearances (CrCl) ranging between 0.58 and 0.97 mL/s (34.5 and 58 mL/min). After 6,12 weeks of treatment with levothyroxin, serum creatinine levels decreased to the range of 80 and 124 µmol/L (0.9 and 1.4 mg/dL) and CrCl increased to 0.74,1.64 mL/s (44,98 mL/min). One patient had proteinuria of 800 mg/day, which decreased to the normal range (<200 mg/day) after levothyroxin treatment. One patient developed acute gouty arthritis before normalization of thyroid-stimulating hormone (TSH), which was successfully managed with prednisone therapy. All of our patients had increased creatine kinase (CK), ranging between 1000 and 2360 U/L (normal range, 22,165 U/L), which normalized after 6 weeks of levothyroxin treatment.

The cross-sectional survey of 705 patients prescribed a hypnotic for insomnia found that more patients taking a Z drug wanted to stop (23 vs 12 per cent prescribed a benzodiazepine) and tried to stop treatment (52 vs 41 per cent). New NICE guidance NICE has published an updated clinical guideline for the management of type 2 diabetes, covering: the control of blood glucose with lifestyle modification, oral hypoglycaemic drugs and insulin; reducing blood pressure and lipids, antithrombotic therapy and estimating cardiovascular risk; and screening and treatment for long-term complications. There is also a new clinical guideline on cardiovascular risk assessment and the modification of blood lipids for the primary and secondary prevention of cardiovascular disease. New technology appraisals include the use of erythropoietin analogues for cancer-associated anaemia, and adalimumab (Humira) and etanercept (Enbrel) for ankylosing spondylitis; infliximab (Remicade) is not recommended. See New from NICE (pages 13-14) for further details. Prescriber consultant editor wins award Professor Tony Avery, professor of primary care at Nottingham University and consultant editor for Prescriber, has won the John Fry Award for his work in promoting the discipline of general practice through research and publishing as a practising GP. The citation acknowledges Professor Avery as ,quite simply one of the best researchers we have had in general practice,' describing his output of original work and research as impressive. The award commemorates the work of the late Dr John Fry, perhaps the most prominent GP of his generation involved in research. Antihypertensive dose ignores adherence Clinicians take no account of poor adherence when they increase the dose of antihypertensive therapy due to apparent lack of effect, US researchers say (Circulation 2008; published online May 27; doi 10.1161/CIRCULATIONAHA.107.724104). Their retrospective analysis included reimbursement records for 38 327 patients with hypertension who presented with elevated BP (140-200/>90mmHg) in one year (mean 1.8 events per patient). After adjusting for potential confounders, they found that antihypertensive medications were added or the dose of medication increased in about one-third of patients regardless of the degree of nonadherence in the previous year. LABAs improve COPD Inhaled long-acting beta2-agonists (LABAs) improve COPD and do not increase the risk of death, a new safety review has concluded (Chest 2008;133:1079-87). The meta-analysis of 27 RCTs in patients with moderate to severe stable COPD found that LABAs reduced exacerbations by 22 per cent, improved lung function, reduced use of rescue medication and improved quality of life. There was no effect on respiratory deaths, though a combination of a LABA with an inhaled steroid reduced the risk by two-thirds compared with LABA monotherapy. Tiotropium (Spiriva) was associated with a 50 per cent lower risk of exacerbations than LABAs. These findings follow the MHRA's review of LABAs in the treatment of asthma, which found no increase in mortality provided they are used with an inhaled steroid (Drug Safety Update 2008;1:9). Naproxen as effective in acute gouty arthritis Naproxen is as effective as prednisolone in the treatment of acute gouty arthritis, say researchers from The Netherlands (Lancet 2008;371:1854-60). Their study in 118 primary care patients showed that five days' treatment with naproxen 500mg twice daily or prednisolone 35mg daily reduced pain scores to a similar extent with a comparable incidence of adverse effects.

Methods In this 8-week, single-blind, double-dummy, dose-ranging study, patients with acute gouty arthritis whose disease was refractory to or who had contraindications to nonsteroidal antiinflammatory drugs and/or colchicine were randomized to receive a single subcutaneous dose of canakinumab (10, 25, 50, 90, or 150 mg; n = 143) or an intramuscular dose of triamcinolone acetonide (40 mg; n = 57). Patients assessed pain using a 100-mm visual analog scale. Results Seventy-two hours after treatment, a statistically significant dose response was observed for canakinumab. All canakinumab doses were associated with numerically less pain than triamcinolone acetonide; thus, a dose with equivalent efficacy to triamcinolone acetonide 72 hours after treatment could not be determined. The reduction from baseline in pain intensity with canakinumab 150 mg was greater than with triamcinolone acetonide 24, 48, and 72 hours after treatment (differences of ,11.5 mm [P = 0.04], ,18.2 mm [P = 0.002], and ,19.2 mm [P < 0.001], respectively), and 4, 5, and 7 days after treatment (all P < 0.05). Canakinumab significantly reduced the risk of recurrent flares versus triamcinolone acetonide (P , 0.01 for all doses) (relative risk reduction 94% for canakinumab 150 mg versus triamcinolone acetonide). The overall incidence of adverse events was similar for canakinumab (41%) and triamcinolone acetonide (42%); most were mild or moderate in severity. Conclusion Our findings indicate that canakinumab 150 mg provides rapid and sustained pain relief in patients with acute gouty arthritis, and significantly reduces the risk of recurrent flares compared with triamcinolone acetonide. [source] Rapid induction of peroxisome proliferator,activated receptor , expression in human monocytes by monosodium urate monohydrate crystalsARTHRITIS & RHEUMATISM, Issue 1 2003Tohru Akahoshi Objective Peroxisome proliferator,activated receptor , (PPAR,) is a member of the nuclear hormone receptor superfamily and functions as a key regulator of lipid and glucose metabolism, atherosclerosis, and inflammatory responses. This study was undertaken to evaluate the biologic role of PPAR, in self-limiting episodes of acute gouty arthritis. To do this, we investigated PPAR, expression by monosodium urate monohydrate (MSU) crystal,stimulated monocytes, and we studied the effects of PPAR, ligands on crystal-induced acute inflammation. Methods PPAR, expression by MSU crystal,stimulated human peripheral blood mononuclear cells was determined by reverse transcription,polymerase chain reaction and immunostaining. Expression of CD36 on monocytes was detected by flow cytometric analysis. The effects of PPAR, ligands on in vitro crystal-induced cytokine production and on in vivo cellular infiltration during crystal-induced acute inflammation were also investigated. Results MSU crystals rapidly and selectively induced PPAR, expression by monocytes. Gene expression was detected as early as 2 hours, and maximum expression was observed at 4 hours after stimulation. The induced PPAR, was functional, since a PPAR, ligand was able to up-regulate CD36 expression on monocytes. A natural ligand of PPAR,, 15-deoxy-,12,14 -prostaglandin J2 (15deoxy-PGJ2), significantly reduced the crystal-induced production of cytokines by monocytes. Indomethacin inhibited cytokine production only at high concentrations, and an antidiabetic thiazolidinedione (troglitazone) failed to exert significant effects. Administration of troglitazone and 15deoxy-PGJ2 significantly prevented cellular accumulation in a mouse air-pouch model of MSU crystal,induced acute inflammation. Conclusion Rapid induction of PPAR, expression on monocytes by MSU crystals may contribute, at least in part, to the spontaneous resolution of acute attacks of gout. [source] | ||||||||||
