Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study is a multi-centre, non-interventional, observational, prospective study with retrospective analysis. The main purpose of the study is to describe the rate of CKD diagnosis in patients with AH and CKD markers. This study will include 10 000 adult outpatients with arterial hypertension, who have one or more Chronic Kidney Disease laboratory markers (without recorded CKD diagnosis prior to enrolment) and have no diabetes mellitus or symptomatic chronic heart failure, who are monitored and treated by cardiologists or internal medicine specialists in approximately 50 outpatient sites in about 20 regions in Russia.

This observational study does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Timely chronic kidney disease (CKD) detection is important for slowing or preventing of kidney function deterioration, reducing cardiovascular complications and mortality. Unfortunately, early-stage CKD is primarily asymptomatic, and due to lack of symptoms CKD is often diagnosed only in advanced stages.

There are limited epidemiological data of the overall CKD prevalence in Russia. In Russia there is Federal diabetes registry that includes data of diabetes kidney disease among others, so the population of patients with diabetes mellitus (DM) and CKD is more studied. Besides the diabetes, AH is also considered one of the major etiological factors for CKD development and progression, but the population of patients with AH and CKD is less studied. Available studies that assess renal function in patients with AH are cross-sectional with one-time assessment of kidney function. The diagnosis of CKD should be established, if CKD markers are observed over 3 or more months, so it is required to assess the markers of kidney function and/or kidney damage overtime to confirm chronic condition.

There is a need to conduct a large observational study in patients with AH and CKD markers to describe the rate of CKD diagnosis in this patient population. Recorded diagnosis of CKD is an important first step to reduce the risk of disease progression and minimize adverse clinical outcomes.

The current study will enroll patients with AH and without previously diagnosed DM and symptomatic heart failure that will allow focusing on evaluating the prevalence of newly diagnosed CKD in patients with hypertension.

This study is a multi-center, non-interventional, observational, prospective study with retrospective analysis.

Planned study population for prospective analysis consists of 10 000 adult outpatients with AH and one or more CKD markers, without recorded CKD diagnosis prior to enrolment, and without recorded diagnosis of DM or symptomatic chronic heart failure (CHF). Planned number of study sites is approximately 50 outpatient sites in about 20 regions of Russia.

Retrospective part includes retrospective review by the physician of paper or electronic medical records of patients with recorded diagnosis of AH for the presence of laboratory CKD markers, measured within the period of ≤12 months prior to inclusion into the study. Patients with one or more CKD markers recorded in their medical records (without recorded CKD diagnosis) can be included in the prospective part of the study.

Demographic and clinical characteristics, including medical history, CKD markers, will be collected retrospectively from all enrolled patients.

In case of enough retrospective data for the period of ≤12 months prior to inclusion to confirm CKD diagnosis according to the current clinical guidelines (two consecutive evaluations of CKD marker(s) with the interval between two measurements not less than 3 months), the CKD diagnosis can be confirmed and recorded. Otherwise, the laboratory testing will be performed to confirm or exclude the CKD diagnosis.

Overall expected duration of the study (from the first patient inclusion to the last patient last visit) is 18 months, or until 10 000 eligible patients are included to the study and data on these patients are collected, whichever occurs first.

This non-interventional study does not imply any intervention into a routine clinical practice, and does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.
