Long-term cardiovascular safety of febuxostat compared with allopurinol in patients with gout (FAST): a multicentre, prospective, randomised, open-label, non-inferiority trial

Background: Febuxostat and allopurinol are urate-lowering therapies used to treat patients with gout. Following concerns about the cardiovascular safety of febuxostat, the European Medicines Agency recommended a post-licensing study assessing the cardiovascular safety of febuxostat compared with allopurinol.Methods: We did a prospective, randomised, open-label, blinded-endpoint, non-inferiority trial of febuxostat versus allopurinol in patients with gout in the UK, Denmark, and Sweden. Eligible patients were 60 years or older, already receiving allopurinol, and had at least one additional cardiovascular risk factor. Those who had myocardial infarction or stroke in the previous 6 months or who had severe congestive heart failure or severe renal impairment were excluded. After a lead-in phase in which allopurinol dose was optimised towards achieving a serum urate concentration of less than 0·357 mmol/L ( < 6 mg/dL), patients were randomly assigned (1:1, with stratification according to previous cardiovascular events) to continue allopurinol (at the optimised dose) or start febuxostat at 80 mg/day, increasing to 120 mg/day if necessary to achieve the target serum urate concentration. The primary outcome was a composite of hospitalisation for non-fatal myocardial infarction or biomarker-positive acute coronary syndrome; non-fatal stroke; or cardiovascular death. The hazard ratio (HR) for febuxostat versus allopurinol in a Cox proportional hazards model (adjusted for the stratification variable and country) was assessed for non-inferiority (HR limit 1·3) in an on-treatment analysis. This study is registered with the EU Clinical Trials Register (EudraCT 2011-001883-23) and ISRCTN (ISRCTN72443728) and is now closed.Findings: From Dec 20, 2011, to Jan 26, 2018, 6128 patients (mean age 71·0 years [SD 6·4], 5225 [85·3%] men, 903 [14·7%] women, 2046 [33·4%] with previous cardiovascular disease) were enrolled and randomly allocated to receive allopurinol (n=3065) or febuxostat (n=3063). By the study end date (Dec 31, 2019), 189 (6·2%) patients in the febuxostat group and 169 (5·5%) in the allopurinol group withdrew from all follow-up. Median follow-up time was 1467 days (IQR 1029–2052) and median on-treatment follow-up was 1324 days (IQR 870–1919). For incidence of the primary endpoint, on-treatment, febuxostat (172 patients [1·72 events per 100 patient-years]) was non-inferior to allopurinol (241 patients [2·05 events per 100 patient-years]; adjusted HR 0·85 [95% CI 0·70–1·03], p less than 0·0001). In the febuxostat group, 222 (7·2%) of 3063 patients died and 1720 (57·3%) of 3001 in the safety analysis set had at least one serious adverse event (with 23 events in 19 [0·6%] patients related to treatment). In the allopurinol group, 263 (8·6%) of 3065 patients died and 1812 (59·4%) of 3050 had one or more serious adverse events (with five events in five [0·2%] patients related to treatment). Randomised therapy was discontinued in 973 (32·4%) patients in the febuxostat group and 503 (16·5%) patients in the allopurinol group.Interpretation:Febuxostat is non-inferior to allopurinol therapy with respect to the primary cardiovascular endpoint, and its long-term use is not associated with an increased risk of death or serious adverse events compared with allopurinol

CODEINE TOXICOKINETICS IN RATS DURING A TWO-YEAR DOSED FEED STUDY

ABSTRACT: Codeine toxlcoklnetics in F344 rats of both sexes were determined durIng a 2-year chronic toxicology study using dosed feed as the exposure route with a 12-hr lIght/dark cycle starting at 7:00 a.m. Rats were allowed to access to dosed feed formulations ad ilbitum with codeine concentrations at 0, 400, 800, and 1600 ppm. BlOOd umples were collected from individual rat on days 7, 21, and 90 at 7:00 p.m., 11:00 p.m., 3:00 a.m., and 7:00 a.m. washed with methylene chloride (15 ml). After discarding the organic phase, the upper aqueous layer (25 ml) was made basic by adding 1 N NaOH (2 ml) and was reextracted with methylene chloride (20 ml). The resulting organic phase(lO ml)was evaporated to dryness, and the residue was reconstituted in 3 ml of methanol containing propiophenone (200 cg/ml) as internal standard, and 7 ml of a diluting solution (1.01 g sodium heptane sulfonate and 5 ml acetic acid in 495 ml water).

Qualitätskultur. Ein Blick in die gelebte Praxis der Hochschulen. Beiträge zur 4. AQ Austria Jahrestagung 2016

Die Publikation zur AQ Austria Jahrestagung 2016 präsentiert in den einzelnen Beiträgen vielfältige Perspektiven, Ansätze, Beispiele und Erfahrungen mit Qualitätskultur und ermöglicht somit einen Blick in die gelebte Praxis der Qualitätskultur an Hochschulen. Die Frage, ob wir eine Qualitätskultur brauchen und was dafür oder dagegen spricht, [wird] in einleitenden Thesen [bearbeitet]. In fünf Foren wurden Kernfragen in Zusammenhang mit Zweck, Bedingungen und Ausgestaltung der Qualitätskultur diskutiert. Es geht u. a. um das Verständnis und den Stellenwert von Qualitätskultur ,das Wechselspiel mit internen und externen Rahmenbedingungen und um die Frage, wie Einstellungen und Werthaltungen der Mitarbeiterinnen und Mitarbeiter im Sinne einer Qualitätskultur gefördert werden können. Weitere Beiträge befassen sich mit dem Verhältnis von Qualitätskultur und externer Qualitätssicherung und damit, wie wirkungsvoll oder auch wirkungslos Qualitätskultur von Hochschulen eingeschätzt wird.

Clinic-based evaluation study of the diagnostic accuracy of a dual rapid test for the screening of HIV and syphilis in pregnant women in Nigeria

<div><p>Background</p><p>Screening pregnant women for HIV and syphilis is recommended by WHO in order to reduce mother-to-child transmission. We evaluated the field performance, feasibility, and acceptability of a dual rapid diagnostic test (RDT) for HIV and syphilis test in antenatal clinic settings in Nigeria.</p><p>Methods and findings</p><p>Participants were recruited at 12 antenatal clinic sites in three states of Nigeria. All consenting individuals were tested according to the national HIV testing algorithm, as well as a dual RDT, the SD BIOLINE HIV/Syphilis Duo Test (Alere, USA), in the clinic. To determine sensitivity, specificity and concordance, whole blood samples were obtained for repeat RDT performance in the laboratory, as well as reference tests for HIV and syphilis. Dual test acceptability and operational characteristics were assessed among participants and clinic staff.</p><p>The prevalence of HIV among the 4,551 enrollees was 3.0% (138/4551) using the national clinic-based HIV testing algorithm. Positive and negative percent agreement of the HIV component of the dual RDT were 100.0% (95% CI 99.7–100.0) and 99.9% (95% CI 99.7–100.0) respectively, when compared with the national rapid testing algorithm. The prevalence of syphilis, using TPHA as the reference test, was low at 0.09% (4/4550). The sensitivity of the syphilis component of the dual RDT could not be calculated as no positive results were observed for patients that were positive for syphilis by TPHA. Each of the only four TPHA-positive specimens had RPR titers of 1:1 (neat), indicative of non-active syphilis. The specificity of the syphilis component of the dual RDT was 99.9% (95% CI 99.8–100.0).</p><p>The dual RDT received favorable feasibility ratings among antenatal care clinic staff. Acceptability among study participants was high with most women reporting preference for rapid dual HIV/syphilis testing.</p><p>Conclusions</p><p>The SD BIOLINE HIV/Syphilis Duo Test showed a high overall diagnostic accuracy for HIV and a high specificity for syphilis diagnosis in antenatal clinic settings. This study adds to a growing body of evidence that supports the clinic-based use of dual tests for HIV and syphilis among pregnant women.</p></div
