Chronic Prostatitis Collaborative Research Network

本提案是对十个临床项目之一的合作协议（合同）邀请的回应。 中心合作建立，执行，维护和评估多种治疗试验， 用于前列腺炎的治疗 和临床样本。将通过以下方式实现长期目标： 1.通过指导委员会的共同努力，制定一项议定书和业务手册 由临床中心、数据协调中心和NIDDK项目科学家组成。的 临床中心的研究者与数据协调中心将负责 在制定议定书方面。 2.招募和接收符合商定诊断入选标准的患者进入研究， 有标准的人口统计信息，与前列腺炎有关的症状，谁将提供临床 将入组在确定的时间间隔采集的样本。 西北大学提出的临床试验是进行一项前瞻性多中心随机盲法安慰剂 锯棕榈（SP）或非洲臀果木（PA）或安慰剂在有以下症状的患者中的对照试验 慢性盆腔疼痛综合征（CPPS）。由于这些药物的广泛使用， 治疗CPPS和男性下尿路症状，且总缺乏整齐的表现 关于疗效和长期效应的研究，需要进行安慰剂对照试验，如使用 CPCRN标准。

This proposal is in response to an invitation for a cooperative agreement (contract) for one of ten clinical centers to collaboratively establish, perform, maintain and evaluate multiple therapeutic trials, either sequentially or concurrently for treatments of prostatitis through the collection and analysis of information and clinical samples from patients with the disorder. The long-term objective will be attained by: 1. Developing a protocol(s) and manual of operations through the joint efforts of the Steering Committee consisting of members of the clinical centers, data coordinating center, and the NIDDK project scientist. The investigator from the clinical centers in conjunction with the data coordinating center, will have responsibility in developing the protocol(s). 2. Recruiting and admitting patients into the study who have met agreed upon diagnostic entry criteria, have standard demographic information, symptoms related to prostatitis and who will provide clinical samples collected at established intervals will be enrolled. Northwestern's proposed clinical trial is to conduct a prospective multi-center randomized blinded placebo controlled trial of Saw palmetto (SP) or Pygeum africanum (PA) or placebo in patients with symptoms of chronic pelvic pain syndrome (CPPS). Because of the widespread use of these medications for the treatment of CPPS and lower urinary tract symptoms in men, and the neat total lack of well-performed studies on the efficacy and long-term effects, a placebo controlled trial is needed as defined using the CPCRN criterion.
