COVID-19 中的气味和鼻用茶碱的功效 (SCENT 3)
COVID-19 中的气味和鼻用茶碱 3 的功效
该 II 期试验的目的是测试鼻内茶碱冲洗治疗 COVID-19 相关嗅觉功能障碍的有效性。 研究人员将比较茶碱鼻冲洗剂与安慰剂鼻冲洗剂对嗅觉症状的影响。 参与者将被要求用溶解在盐水中的药物或安慰剂胶囊冲洗鼻子,每天两次,持续 12 周,并在治疗前、治疗期间和治疗结束时填写有关气味的调查。
这项研究还将用于描述与鼻内茶碱冲洗相关的不良反应。
研究概览
详细说明
与 COVID 相关的嗅觉功能障碍 (OD) 是 SARS-COV-2 感染的主要症状,影响高达 80% 的 COVID-19 患者。 虽然发病机制的研究正在进行中,但预计有相当一部分人会患有长期 OD。 研究人员试图测试鼻内茶碱鼻腔冲洗作为治疗新冠肺炎相关 OD 持续超过 3 个月的潜在治疗选择。
初步研究表明,茶碱可改善病毒后 OD 的结果,初步数据表明,茶碱对新冠肺炎后 OD 患者具有治疗益处,且全身吸收极少。
主要假设是,对于 COVID-19 相关的 OD 症状,茶碱冲洗比安慰剂盐水冲洗更有效。 使用鼻内茶碱的副作用很小。

纳入标准:
将根据以下纳入标准招募参与者:
- 年龄 18 至 75 岁的男性和女性

临床全球印象 - 改进量表
大体时间:第12周
|
临床全球印象改进量表(CGI-I)是一种主观评分量表,用于衡量患者随时间变化的变化。 它的范围从1到7,其中1表示“非常有所改善”,2表示“改进”,3表示“最小改进”,4表示“无变化”,5表示“最小情况更糟”,6表示“更糟”,而7表示“非常恶化”。 在这项研究中,在CGI-I上报告1、2或3的参与者被认为是对治疗的反应者。 主要分析将比较茶碱和安慰剂组之间评估受试者内部变化随时间和组间差异的比例。 我们将衡量定义为参与者自我报告的最小变化或临床全球印象量表(CGI)量表的响应率,除以每个组的参与者数量。主要比较将集中在12周的变化上 |

嗅觉功能障碍结果等级
大体时间:6周零12周
|
嗅觉功能障碍结果评级(气味)是一项特定疾病的问卷,可评估任何病因的嗅觉功能障碍的参与者的身体,功能和情绪限制。 该仪器包含28个总项目,每个项目的评分为5分李克特量表从0到4。 总分范围从0到112。 较高的分数表明功能障碍和限制程度更高。 |
6周零12周
|
|
评估依从性
大体时间:12周
|
将联系参与者,以报告前7天内完成的灌溉次数14。 参与者通过在REDCAP调查中进行的自我报告措施报告了他们对每日两次鼻腔灌溉的遵守,包括他们完成了多少冲洗。 措施计数代表了每天两次灌溉的自我报告的依从性。 |
12周
|
|
盲人评估
大体时间:在头三周内
|
在这项研究中对盲人的评估涉及在开始鼻腔灌溉后的头三个星期内与参与者联系,并询问他们认为他们被分配给“茶碱和鼻盐灌溉”或“单独鼻水灌溉”。 报告的数字表示有多少参与者正确地猜到了他们被分配给的手臂。 |
在头三周内
