Active clinical trials for "Necrosis"

An increase in cardiac biomarkers has been shown to occur in 5% to 30% of patients after otherwise successful percutaneous coronary interventions (PCIs)(1) Apart from side-branch occlusion, intimal dissection and coronary spasm, a possible aetiology of myonecrosis after PCI might be distal embolization of atherogenic materials from plaque disruption,(2 )causing obstruction of blood flow at capillary level resulting in micro-infarction.(3,4 )Recent studies have suggested that pretreatment with Atorvastatin may be associated with a reduction in infarct size after elective PCI. (5-7 ). Actually the standard pretreatment in patients undergoing elective coronary-PCI and already treated with aspirin is clopidogrel loading dose administration before procedure.(8,9)The investigators compared a high (80mg) re-loading dose of Atorvastatin with a high loading dose of Rosuvastatin (40 mg) both administered within 24h before the procedure in reducing the rate of periprocedural MI. Therefore, the investigators will conduct a single center, prospective randomized study to assess whether a single, high (80mg) loading (within 24h)dose of Atorvastatin compared with a single loading dose of Rosuvastatin (20 mg) is effective in preventing elevation of biomarkers of MI after elective coronary stent implantation. We evaluate the incidence of MACCE(occurring of cardiac death, myocardial infarction (including periprocedural myonecrosis) and stroke at 30 days 6 and 12 month follow-up.

This prospective clinical study is to demonstrate the efficacy and safety of ReCap Total Hip Resurfacing System.

Evaluate the safety and efficacy of the CeramTec Acetabular Alumina Insert and CeramTec Alumina head when used with the Foundation Porous Coated Acetabular Shell and an Encore hip stem.

This pilot study will investigate the safety and effect of etanercept in HIV infection by studying HIV replication and immune function (as measured by CD4 counts) in individuals with HIV infection.

This study is to assess the clinical efficacy of epidural injections with Tumor Necrosis Factor-Alpha(TNF-α) Inhibitor in patients with chronic radicular pain caused by lumbar spinal stenosis.

This is a single center, prospective, randomized controlled study. The primary objective of this study is to measure migration over two years with RSA. Patients will be randomized in two arms, receiving a Taperloc Complete Reduced Distal or a Taperloc Complete Microplasty hip stem.

To demonstrate safety and effectiveness of lumen-apposing metal stents for resolution of walled off pancreatic necrosis (WONs) in patients with WONs with solid component >30%.

In this study, the researchers will investigate the effect of single-file reciprocating versus single-file rotational file systems on the postoperative pain in adult patients who have necrotic pulp and apical periodontitis. The participants will be assigned by chance to separate groups that compare 2 different treatments, reciprocating single-file system (Reciproc Blue) and rotational single-file system (OneShape). As a reference, Mtwo multi-file (full-sequence) will be used.

The research design is a randomized prospective clinical trial comparing Endoscopic ultrasound (EUS) guided drainage of WON using FCSEMS and plastic stents. The trial will be conducted at the Florida Hospital Center for Interventional Endoscopy, Orlando, Florida.

This is a randomized, double-blind, multicentral clinical trial to investigate the efficacy and safety of Recombinant Human Tumor Necrosis Factor-α Receptor Ⅱ IgG Fc fusion protein injection (Yisaipu®) in the treatment of active axial spondyloarthritis(SpA). The primary purpose is to assess the different situations in maintaining treatment programme in SpA patients with controlled inflammation by Yisaipu®. And the second purpose is to assess the eficacy and safety of Yisaipu® in axial SpAs. The trial will include 150 patients with stable NSAIDs therapy, and at the first stage they will receive 24-week full-dose of Yisaipu®. Then at the second stage the patients who achieve low disease activity (LDA, ASDAS<2.1) at 24th week will be randomizedly divided into three group: full-dose of Yisaipu® group, half-dose of Yisaipu® group and placebo group. And the blind stage will last for 48 weeks. Patients who complete the 72-week therapy or achieve disease-flare criteria during the blind stage would finish the study.
