Abstract This novel prospective cohort study will explore the relationship between kidney transplantation (antibiotics, antivirals, and immunosuppressants), changes in the composition and functional gene content of the microbiome, and the incidence and severity of patient reported symptoms before and after patients receive a kidney transplant from a live donor. We have selected living donor recipients to reduce the chance of missing samples, as these are scheduled surgeries. Thirty-nine subjects will provide stool and sputum samples for shot gun metagenomic sequencing of the microbiome before transplant, during the first week after transplant prior to discharge, and at 3 months after the transplant. Demographic (age, gender, race/ethnicity, income, education) and disease specific data (HT/WT/BMI, creatinine, estimated glomerular filtration rate, basic metabolic panel, complete blood count), and medication adherence data (electronic medication adherence monitoring and tacrolimus trough levels) will be collected. Potential confounding variables will include: historical use of antibiotics, concomitant medications, mode of delivery (vaginal vs. caesarian birth), and nutritional status (Diet History Questionnaire III). Incidence and severity of symptoms of fatigue, sleep dysfunction, and anxiety/depression–like symptoms will be measured using the Patient Reported Outcome Measurement Systems (PROMIS) 57 v2.1. Health related quality of life will be assessed using the Kidney Disease Quality of Life Short Form (KDQOL-SF v1.3). This research will support the mission of the National Institute of Nursing Research (NINR) to promote and improve the health and quality of life of individuals, families, and communities. The proposed study will contribute to the NINR mission by: 1) Exploring the mechanisms underlying incidence and severity of symptoms after kidney transplantation with the goal of developing personalized treatments, including pre-probiotics supplementation, lifestyle modification, and dietary interventions that address these mechanisms through symptom science research; 2) Helping individuals with chronic kidney disease/kidney transplant recipients better understand and manage these conditions by engaging individuals as active participants in managing their own health through awareness of modifiable factors that alter the microbiome; and 3) Promoting the development of innovative, multidisciplinary, nurse-led teams to advance research on microbiome and health after kidney transplantation.

抽象的 这项新颖的前瞻性队列研究将探讨肾移植（抗生素、 抗病毒药和免疫抑制剂），其组成和功能基因含量的变化 微生物组，以及患者在接受治疗之前和之后报告的症状的发生率和严重程度 我们选择了活体捐献者的肾移植，以减少缺失的机会。 样本，因为这些是预定的手术，三十九名受试者将提供粪便和痰样本进行注射。 移植前、移植后第一周内对微生物组进行宏基因组测序 出院时以及移植后 3 个月时进行人口统计（年龄、性别、种族/民族、收入、 教育）和疾病具体数据（HT/WT/BMI、肌酐、估计肾小球滤过率、基本 代谢组、全血细胞计数）和药物依从性数据（电子药物依从性） 收集的潜在混杂变量包括： 历史数据。 抗生素的使用、合并用药、分娩方式（阴道分娩与剖腹产）以及营养 状态（饮食史问卷 III）。疲劳、睡眠功能障碍和症状的发生率和严重程度。 将使用患者报告结果测量来测量焦虑/抑郁样症状 系统 (PROMIS) 57 v2.1 将使用肾脏疾病质量来评估与健康相关的生活质量。 生命简表 (KDQOL-SF v1.3) 这项研究将支持国家护理研究所的使命。 促进和改善个人、家庭和社会的健康和生活质量的研究（NINR） 拟议的研究将通过以下方式为 NINR 使命做出贡献： 1) 探索机制。 肾移植后症状的潜在发生率和严重程度，旨在发展 个性化治疗，包括补充益生菌、改变生活方式和饮食 通过症状科学研究解决这些机制的干预措施；2) 帮助患有此病的个体； 慢性肾病/肾移植受者可以通过以下方式更好地了解和管理这些疾病 通过认识可改变的因素，让个人积极管理自己的健康 改变微生物组的因素；3) 促进创新、多学科、护士主导的发展 团队推进肾移植后微生物组和健康的研究。
