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
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.

Primary composite endpoint
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.
