A Cohort Study on the Integrated Management of Chronic Kidney Disease

Обзор

The study will leverage the established multi-stage cohort resources at Huashan Hospital, covering the entire spectrum from early-stage CKD to dialysis, including a comorbidity real-world database, a prospective CKD patient cohort, and a maintenance hemodialysis patient real-world cohort. It will also collaborate with the Shanghai Fifth People's Hospital (community-based CKD cohort, n\>2,000) and the Jing'an District Central Hospital (end-stage renal disease cohort, n\>400) as external validation platforms. Using epidemiological and big data-driven approaches, the study aims to elucidate the mechanisms underlying disease progression and complications, construct intelligent intervention models, and validate their performance in the external cohorts, ultimately facilitating the optimization and broader application of comprehensive CKD management strategies.

Подробное описание

This study is a multi-center, bidirectional cohort study. The research data are primarily derived from the multidisciplinary clinical cohort of chronic kidney disease (CKD) established by the Department of Nephrology at Huashan Hospital, Fudan University, and are supplemented by external validation platforms at Shanghai Fifth People's Hospital and Shanghai Jing'an District Central Hospital.

The study will systematically integrate and utilize the multidimensional cohort resources already established at Huashan Hospital, covering the entire spectrum from early-stage CKD to dialysis, including a real-world database of comorbid populations, a prospective cohort of CKD patients, and a real-world cohort of maintenance hemodialysis patients. Using epidemiological and big data-driven computational approaches, the study will focus on exploring comorbidity patterns associated with CKD and establishing an early classification and early warning system; it will also investigate the mechanisms underlying the progression of kidney disease and related complications such as cardiovascular disease, nutritional and metabolic abnormalities, and osteoporosis, and develop intelligent intervention models. Based on these findings, the study will propose the concept of metabolic balance and accordingly establish precision nutrition and drug evaluation protocols.

To ensure the generalizability and reliability of the research outcomes, this study will conduct external validation and effectiveness evaluation of the previously constructed comorbidity patterns, early warning system, and management protocols in the community-based CKD cohort (over 2,000 participants) at Shanghai Fifth People's Hospital and the end-stage renal disease cohort (over 400 participants) at Jing'an District Central Hospital. This will facilitate the widespread application and continuous optimization of the comprehensive CKD management program.

Вмешательства

• Другое Retrospective data collection
  Retrospective data from the maintenance hemodialysis cohort at Huashan Hospital (Sept 2018-Sept 2025) include: Demographics: age, sex, education, smoking/alcohol, primary disease, dialysis vintage. Dialysis treatment: repeated measures of weight, BP, heart rate, arterial/venous/transmembrane pressures, ultrafiltration rate, session time, dialyzer type, blood flow, and medications. Complication control:Nutrition: lipids, glucose, prealbumin, albumin, BMI, nPCR;Bone mineral: Ca, P, PTH, 25(OH)D
• Другое Prospective data collection
  Research data are primarily derived from the prospective CKD cohort at Huashan Hospital Integrated CKD Management Clinic. Baseline includes: age, sex, education, smoking/alcohol, primary disease. Follow-up (every 3 months): 3-day diet diary (via app/paper) to calculate P/Ca/protein intake; indirect calorimetry for resting energy expenditure; nutritional supplement use. Physical: handgrip, gait speed (sarcopenia), DEXA bone density. Questionnaires: frailty, ADL, QoL, symptom scores. Labs (rep
• Другое External validation
  The research data are primarily based on the previously established community-based chronic kidney disease (CKD) cohort at Shanghai Fifth People's Hospital and the end-stage renal disease (ESRD) cohort at Shanghai Jing'an District Central Hospital, which serve as external validation and the data contents are the same as the retrospective data collection.

Критерии участия

Критерии включения

Prospective:

• Patients who have documented outpatient or inpatient records at Huashan Hospital, Shanghai Fifth People's Hospital, or Jing'an District Central Hospital during the period from September 2018 to September 2025.
• Aged 18-90 years.
• Diagnosed with one or more of the 48 pre-specified common chronic diseases according to ICD-10 codes.
• Patients diagnosed with end-stage renal disease (CKD stage 5) and receiving long-term maintenance hemodialysis, with a dialysis vintage of at least 3 months.
• Have relatively complete hemodialysis records available at the participating center.

Retrospective:

• Patients who meet the diagnostic criteria for chronic kidney disease (CKD) stages 1-5 (non-dialysis) as defined by the KDIGO guidelines, with a disease duration of at least 3 months.
• Aged 18-80 years, with normal cognitive ability to independently, or with the assistance of a caregiver, complete dietary diaries and quantitative assessments, and willing to provide written informed consent voluntarily.
• Able to comply with regular outpatient follow-up visits and willing to record a 3-day dietary diary (including both weekdays and weekends) as required.

Критерии исключения

Prospective:

• Patients whose dialysis-related data and key clinical variables (e.g., creatinine, proteinuria, and other outcome-related indicators) are missing or severely illogical, and which are deemed unusable for research purposes upon evaluation.
• Patients with poor compliance during dialysis, or those receiving palliative dialysis.
• Other conditions that the investigators consider inappropriate.

Retrospective:

• Patients who have experienced acute kidney injury within 3 months prior to enrollment, or who are in an acute stress state such as acute infection, myocardial infarction, or other acute conditions at the time of screening.
• Patients with severe cognitive impairment, mental illness, or insurmountable communication barriers that prevent accurate provision of metabolic assessment information.
• Pregnant or lactating women; patients currently participating in other drug interventional clinical trials that may interfere with the outcome assessment of this study.
