简要总结
UPRIGHT-HTM will compare risk stratification, treatment efficiency and health economic outcomes of a diagnostic approach based on home blood pressure telemonitoring combined with urinary proteomic profiling with home blood pressure telemonitoring alone
详细描述
Hypertension is by far the dominant reversible risk factor dwarfing most others in the pathogenesis of chronic kidney disease (CKD) and diastolic left ventricular dysfunction (DVD), two archetypes of chronic age-related diseases, which are rampant in ageing societies in epidemiological transition. Home blood pressure telemonitoring (HTM) is a recommended approach in the diagnosis and management of hypertension. Urinary peptidomic profiling (UPP) holds great promise in individualising prevention and treatment of CKD and DVD and associated complications, such as coronary heart disease. Making use of these modern technologies, UPRIGHT-HTM is an investigator-initiated randomised clinical trial with a patient-centred design, for the first time, comparing HTM combined UPP (experimental group) to HTM alone (control group) in risk profiling and as guide to starting or intensifying management of risk factors to prevent established disease. The trial will run in Europe, sub-Saharan Africa and South America. Eligible patients, aged 55-75 years old, are asymptomatic, but have three or more CKD- or DVD-related risk factors, preferably including hypertension, type 2 diabetes mellitus, or both, and do have internet skills. The primary endpoint consists of a composite of new-onset intermediate endpoints (microalbuminuria, progression of CKD, diabetic or hypertensive retinopathy, electrocardiographic or echocardiographic left ventricular hypertrophy or DVD and hard outcomes (cardiovascular mortality and non-fatal complications, including myocardial infarction, heart failure and stroke). Secondary objectives are demonstrating that combining HTM with UPP is feasible and cost-effective in a multicultural context, defining the molecular signatures of early CKD and DVD, and with help of stakeholders educating and empowering patients. Assuming an accrual time of 1 year, a median follow-up of 4 years, a 10% dropout rate, a 20% risk of the primary endpoint in the control group and 30% risk reduction in the experimental group, requires 1000 patients to be randomised in a 1:1 proportion with the two-sided alpha level and power set 0.05 and 0.80, respectively. The expected outcome is proving the superiority in terms of efficiency and cost-effectiveness of HTM combined with UPP vs HTM alone, which should lead to redesigning the clinical workflow, putting greater emphasis on preventing rather than curing established disease.

盲法说明
Caregivers will know the group to which their patients were randomly assigned. In the two groups, both patients and caregivers will have full access to the HTM data. In both treatment groups, caregivers will be informed about the UPP risk profile. However, in the experimental group, patients will be informed about their UPP risk profile shortly after randomisation and in the control group, only when they leave randomised follow-up or at the completion of the trial. The central study coordinating team will remain blinded to the primary endpoint and all of its components until completion of the trial and until all datasets have been cleaned and frozen for the final analysis.

Incidence of nonfatal stroke
时间窗: After a run-in period of 2 to 5 weeks to check the eligibility, patients will be randomized and followed up for 4 years
ICD10 codes I60-I63
Primary composite endpoint
时间窗: After a run-in period of 2 to 5 weeks to check the eligibility, patients will be randomized and followed up for 4 years
The primary endpoint is a composite of intermediary and "hard" cardiovascular-renal endpoints. The "intermediate endpoints" are diabetic nephropathy, progression to a higher CKD stage, doubling of serum creatinine, an eGFR decrease by 30% or more or eGFR declining below 45 ml/min/1.73 m2, new-onset hypertensive or diabetic retinopathy, electrocardiographic or echocardiographic left ventricle hypertrophy, and diastolic left ventricular dysfunction. The "hard" composite cardiovascular endpoint includes cardiovascular mortality, and nonfatal myocardial infarction, nonfatal hospitalised heart failure, and nonfatal stroke, not including transient ischemic attack. The "hard" renal outcomes include macroalbuminuria, the need for renal-replacement therapy, and death to renal causes.
Change in serum creatinine (mg/dl)
时间窗: After a run-in period of 2 to 5 weeks to check the eligibility, patients will be randomized and followed up for 4 years
The concentration of creatinine in serum, expressed in mg/dl, will be measured, using Jaffe's method with modifications () in certified laboratories applying isotope-dilution mass spectrometry for calibration (Clin Chem 2006; 52: 5-18).
Change in eGFR (ml/min/1.73m2)
时间窗: After a run-in period of 2 to 5 weeks to check the eligibility, patients will be randomized and followed up for 4 years
eGFR will be derived from the serum creatinine concentration by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation (Ann Intern Med 2009; 150: 604-612) and expressed in ml/min/1.73 m2.
Progression of CKD
时间窗: After a run-in period of 2 to 5 weeks to check the eligibility, patients will be randomized and followed up for 4 years
