Several Treatments (several + treatment)
Terms modified by Several Treatments Selected AbstractsUpper digestive bleeding in cirrhosis.HEPATOLOGY, Issue 3 2003Post-therapeutic outcome, prognostic indicators Several treatments have been proven to be effective for variceal bleeding in patients with cirrhosis. The aim of this multicenter, prospective, cohort study was to assess how these treatments are used in clinical practice and what are the posttherapeutic prognosis and prognostic indicators of upper digestive bleeding in patients with cirrhosis. A training set of 291 and a test set of 174 bleeding cirrhotic patients were included. Treatment was according to the preferences of each center and the follow-up period was 6 weeks. Predictive rules for 5-day failure (uncontrolled bleeding, rebleeding, or death) and 6-week mortality were developed by the logistic model in the training set and validated in the test set. Initial treatment controlled bleeding in 90% of patients, including vasoactive drugs in 27%, endoscopic therapy in 10%, combined (endoscopic and vasoactive) in 45%, balloon tamponade alone in 1%, and none in 17%. The 5-day failure rate was 13%, 6-week rebleeding was 17%, and mortality was 20%. Corresponding findings for variceal versus nonvariceal bleeding were 15% versus 7% (P = .034), 19% versus 10% (P = .019), and 20% versus 15% (P = .22). Active bleeding on endoscopy, hematocrit levels, aminotransferase levels, Child-Pugh class, and portal vein thrombosis were significant predictors of 5-day failure; alcohol-induced etiology, bilirubin, albumin, encephalopathy, and hepatocarcinoma were predictors of 6-week mortality. Prognostic reassessment including blood transfusions improved the predictive accuracy. All the developed prognostic models were superior to the Child-Pugh score. In conclusion, prognosis of digestive bleeding in cirrhosis has much improved over the past 2 decades. Initial treatment stops bleeding in 90% of patients. Accurate predictive rules are provided for early recognition of high-risk patients. [source] Effect of immunoadsorption on refractory idiopathic focal and segmental glomerulosclerosis,JOURNAL OF CLINICAL APHERESIS, Issue 4 2006Christian Kuhn Abstract A case of a young adult with refractory nephrotic syndrome due to focal segmental glomerulosclerosis is reported. Several treatments had been used without success including steroids, cyclophosphamide, cyclosporine A, tacrolimus, and mycophenolate mofetil. Immunoadsorption was performed as a last resort to manage the nephrotic syndrome, which led to a drastic urinary protein reduction. We review the literature supporting immunoadsorption in primary focal segmental glomerulosclerosis. J. Clin. Apheresis. © 2006 Wiley-Liss, Inc. [source] Techniques for Acute Stroke InterventionJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 1 2009RAJAN A.G. PATEL M.D. Stroke or cerebrovascular accident is the second most common cause of death in Western countries. Although stroke is a treatable disease, the majority of patients do not receive intravenous thrombolysis or catheter-based therapy. The lack of treatment is multifactorial. Several treatments have been studied. Research and development in the area of acute stroke treatment are ongoing. [source] Pathogenesis, detection and treatment of Achilles tendon xanthomasEUROPEAN JOURNAL OF CLINICAL INVESTIGATION, Issue 4 2005S. G. Tsouli Abstract Tendon xanthomatosis often accompanies familial hypercholesterolaemia, but it can also occur in other pathologic states. Achilles tendons are the most common sites of tendon xanthomas. Low-density lipoprotein (LDL) derived from the circulation accumulates into tendons. The next steps leading to the formation of Achilles tendon xanthomas (ATX) are the transformation of LDL into oxidized LDL (oxLDL) and the active uptake of oxLDL by macrophages within the tendons. Although physical examination may reveal Achilles tendon xanthomas (ATX), there are several imaging methods for their detection. It is worth mentioning that ultrasonography is the method of choice in everyday clinical practice. Although several treatments for Achilles tendon xanthomas (ATX) have been proposed (LDL apheresis, statins, etc.), they target mostly in the treatment of the basic metabolic disorder of lipid metabolism, which is the main cause of these lesions. In this review we describe the formation, detection, differential diagnosis and treatment of ATX as well as the relationship between tendon xanthomas and atheroma. [source] Latest news and product developmentsPRESCRIBER, Issue 22 2007Article first published online: 28 DEC 200 Glitazones: benefits outweigh the risks Following a review of the safety of rosiglitazone and pioglitazone, the European Medicines Agency (EMEA) has concluded that their benefits outweigh their risks in the approved indications. The review was prompted by reports of an increased risk of fractures in women and, in patients taking rosiglitazone, ischaemic heart disease. The EMEA concluded that prescribing information for rosiglitazone should now include a warning that, in patients with ischaemic heart disease, it should only be used after careful evaluation of each patient's individual risk, and the combination of rosiglitazone and insulin should only be used in exceptional cases and under close supervision. No change was considered necessary to the prescribing information for pioglitazone. Modern dressings no better? A systematic review has found only weak evidence that modern dressings are better than saline gauze or paraffin gauze for healing acute and chronic wounds (Arch Dermatol 2007;143: 1297-304). The analysis, which included 99 studies, found that only hydrocolloids were demonstrably better than older dressings for healing chronic wounds, and alginates were superior to other modern dressings for debriding necrotic wounds. There was no evidence that modern dressings offered superior overall performance to the older alternatives. Hospital inflation twice primary care level The cost of drugs prescribed in secondary care but dispensed in the community increased by 6.4 per cent in 2006 - twice the rate of inflation in primary care - according to the latest statistics on hospital prescribing in England. The increase follows a reduction in costs in 2005 after the introduction of the new PPRS scheme. Data from The Information Centre (www.ic.nhs.uk) show that hospital medicines make up about 24 per cent of the NHS drugs budget. Secondary care has a consistently better record than primary care in prescribing lower-cost alternatives within therapeutic categories, eg simvastatin and pravastatin among the statins, omeprazole and lansoprazole among PPIs, and ACE inhibitors among drugs acting on the renin angiotensin system. The most expensive drug prescribed by hospital specialists and dispensed in the community is interferon beta. MHRA limits the use of fibrates The Medicines and Healthcare products Regulatory Agency (MHRA) has advised that fibrates should now be reserved for the treatment of isolated severe hypertriglyceridaemia. They should be considered for hypercholesterolaemia only when a statin or other treatment is contraindicated or not tolerated. In the latest Drug Safety Update, the MHRA says there is insufficient evidence of long-term benefits from fibrates, and first-line use is no longer justified because the evidence for the benefits of statins is robust. The MHRA also warns that some breastfeeding infants have increased susceptibility to the adverse effects of codeine taken by their mother, and that St John's wort may affect the hepatic metabolism of any anticonvulsant. Annual zoledronic acid infusion cuts mortality after hip fracture Once-yearly infusion of zoledronic acid (Aclasta) after hip fracture reduces deaths over a two-year period by 28 per cent compared with placebo, US investigators say (N Engl J Med 2007;357:1799-809). The HORIZON Recurrent Fracture Trial randomised 2127 men and women (mean age 75) within 90 days of surgery for hip fracture to zoledronic acid 5mg yearly or placebo. Mortality over 1.9 years of follow-up was 9.6 per cent with zoledronic acid and 13.3 per cent with placebo. Zoledronic acid also significantly reduced the rate of any new clinical fractures (by 35 per cent) and new clinical vertebral fractures(by 45 per cent),but the lower rate of hip fracture (2.0 vs 3.5 per cent with placebo) was not statistically significant. Rivastigmine patch for mild to moderate AD Rivastigmine (Exelon) is now available as a transdermal patch for the treatment of mild to moderate Alzheimer's disease. Applied once daily, the patch delivers 9.5mg per 24 hours and, says manufacturer Novartis, is associated with a lower incidence of nausea and vomiting than a comparable oral dose. The patch is available in two strengths: 4.6mg per 24hr is equivalent to oral doses of 3 or 6mg per day, and the 9.5mg per 24hr patch is equivalent to 9 or 12mg per day orally. The recommended dose of the patch is 9.5mg per day; both strengths cost £83.84 for 30 patches. Women more aspirin resistant than men? The cardioprotective effect of low-dose aspirin may be lower in women than men, say Canadian investigators (BMC Medicine 2007;5:29 doi: 10.1186/1741-70155-29). Their meta-analysis of 23 randomised trials involving a total of 113 494 participants found that aspirin significantly reduced the risk of nonfatal but not fatal myocardial infarction (MI). About one-quarter of the variation in its effects on nonfatal MI was accounted for by the sex mix of the trial population. Separating the results by sex showed the reduction in risk with aspirin use was statistically significant in men (relative risk, RR, 0.62) but not in women (RR 0.87). Look after physical health of mentally ill GPs and other primary care workers should take more responsibility for the physical health of their mentally ill patients, say advocacy groups. Mind and Body: Preventing and Improving Physical Health Problems in Patients With Schizophrenia points out that the mental health needs of patients with schizophrenia are met in secondary care, but their physical health needs should be met in primary care. In particular, the metabolic effects of antipsychotics may lead to obesity, diabetes and cardiovascular disease, and weight gain in particular is a frequent reason for nonadherence to treatment. The Mind and Body Manifesto was developed by SANE, The Mental Health Nurses Association, The National Obesity Forum and The Disability Rights Commission and sponsored by Bristol-Myers Squibb Pharmaceuticals Limited and Otsuka Pharmaceuticals (UK) Ltd.

Health eCard costs Some costs quoted in our article on the Health eCard (The Health eCard: the way ahead for medical records?,5 October issue, pages 28-9) have been revised: the card and initial download will cost patients £39.50, and GPs will be entitled to charge patients £10 per annum for subsequent downloads. NICE appraisals of cytokine inhibitors in RA NICE has endorsed the use of the anti-TNF agents adalimumab (Humira), etanercept (Enbrel) and infliximab (Remicade), normally in conjunction with methotrexate, for the treatment of active RA when methotrexate and another DMARD have failed (also see New from NICE below). NICE has provisionally concluded, subject to consultation, that abatacept (Orencia) should not be recommended for the treatment of RA. Boots and BMJ launch health advice site www.askbootshealth.com is a new website providing information about health and medicines for the public produced by Boots using information provided by the BMJ Publishing Group. The website covers many of the topics already available from NHSDirect, with perhaps more information about available treatments. Diabetes care shows small improvement The third National Diabetes Audit in England and Wales has found that more people with diabetes were achieving the targets set by NICE for cholesterol levels, glycaemic control and blood pressure in 2005/06 - but younger patients were doing less well. Overall, the HbA1C target of ,7.5 per cent was achieved in 60 per cent of people with diabetes compared with 58 per cent in 2004/05. However, HbA1C was >9.5 per cent in 30 per cent of children and young people, of whom 9 per cent experienced at least one episode of ketoacidosis. More topics for NICE New topics referred to NICE include clinical guidelines on ovarian cancer, coeliac disease and stable angina, public health guidance on preventing cardiovascular disease, and technology appraisals on insulin detemir (Levemir) for type 1 diabetes, several treatments for cancer and hepatic and haematological disorders, and biological therapies for juvenile arthritis. New from NICE NICE appraisal on anti-TNFs for RA Since NICE published its first appraisal of agents acting against tumour necrosis factor-alpha (anti-TNFs) for the treatment of RA in 2002, the product licences for etanercept (Enbrel) and infliximab (Remicade) have changed and a new agent, adalimumab (Humira), has been introduced. The anti-TNFs act in different ways. Infliximab is a chimeric monoclonal antibody that binds to TNF-alpha, neutralising its activity. Etanercept, a recombinant human TNF-alpha receptor fusion protein, and adalimumab, a human-sequence antibody, both bind to TNF-alpha and block its interaction with cell surface receptors. Adalimumab also modulates some biological responses induced or regulated by TNF-alpha. These agents are recommended for adults with severe active RA (defined as a disease activity score - DAS28 - greater than 5.1) who have already tried two disease-modifying drugs, including methotrexate (if not contraindicated). Prior treatment should have been of at least six months' duration, including two months at the standard dose (unless limited by toxicity). Anti-TNFs should normally be prescribed with methotrexate; when this is not appropriate, etanercept and adalimumab may be prescribed as monotherapy. Treatment with an anti-TNF should be continued beyond six months only if there is an adequate response (defined as an improvement in DAS28 of at least 1.2). Data from the British Rheumatology Society Biologics register show that, after six months, 67 per cent of patients met NICE criteria for an adequate response; this declined to 55 per cent at 18 months. The basic annual cost of treatment is £9295 for adalimumab 40mg on alternate weeks or etanercept 25mg twice weekly; infliximab costs £3777 for a loading dose, then £7553-£8812 depending on dose. Assuming no progression of disability, the incremental costs per QALY (compared with sequential DMARDs) were £30 200 for adalimumab, £24 600 for etanercept and £39 400 for infliximab. There are no direct comparative trials of the anti-TNFs, and their clinical trial findings are not directly comparable. Unless other factors determine treatment choice, NICE therefore recommends the least expensive. If the first anti-TNF is withdrawn within six months due to an adverse event, a second may be tried. [source] An Adaptive Two-stage Design with Treatment Selection Using the Conditional Error Function ApproachBIOMETRICAL JOURNAL, Issue 4 2006Jixian Wang Abstract As an approach to combining the phase II dose finding trial and phase III pivotal trials, we propose a two-stage adaptive design that selects the best among several treatments in the first stage and tests significance of the selected treatment in the second stage. The approach controls the type I error defined as the probability of selecting a treatment and claiming its significance when the selected treatment is indifferent from placebo, as considered in Bischoff and Miller (2005). Our approach uses the conditional error function and allows determining the conditional type I error function for the second stage based on information observed at the first stage in a similar way to that for an ordinary adaptive design without treatment selection. We examine properties such as expected sample size and stage-2 power of this design with a given type I error and a maximum stage-2 sample size under different hypothesis configurations. We also propose a method to find the optimal conditional error function of a simple parametric form to improve the performance of the design and have derived optimal designs under some hypothesis configurations. Application of this approach is illustrated by a hypothetical example. (© 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source] |
