About this study

Official title: Comparison Between Centrally Measured Blood Pressure and Automated Blood Pressure Monitoring for Detection of Early Kidney Dysfunction in Patients With Primary Hypertension

The present study aims to show the difference of blood pressure monitored centrally and automated BP monitoring among patients with primary hypertension for early detection of kidney dysfunction

Read the detailed description

Hypertension is well known as the silent killer, There is a close relationship between blood pressure levels and the risk of cardiovascular events, strokes and kidney disease.

Diabetes and hypertension cause up to two-thirds of chronic kidney disease , chronic kidney disease is a common condition characterized by evidence of kidney damage or dysfunction.

chronic kidney disease is currently classified based on a patient's estimated glomerular filtration rate and urinary albumin excretion rate , clinicians look for markers of renal damage (e.g., abnormalities of urinary sediment or organ structure) to diagnose chronic kidney disease in people with estimated glomerular filtration rate of <60 mL/min/1.73 m2.

Age distribution for hypertension showed progressive rise in blood pressure with increasing age. Age-related hypertension appears to be predominantly systolic rather than diastolic. The third NHANES survey reported that the prevalence of hypertension grows significantly with increasing age in all sex and race groups. In another study, the incidence of hypertension appeared to increase approximately 5% for each 10-year interval of age Because Central blood pressure is considered better than peripheral blood pressure in predicting cardiovascular events, due to wave reflections and viscoelastic properties of the arterial wall Now a day several non-mercury techniques have been developed during the last ten years in order to gradually supplant the mercury-auscultatory method, such as the automatic electronic devices using algorithms based on the oscillometric technique.

Over the last ten years , different protocols are used to validate the accuracy of blood pressure measuring devices , several automated devices have been successfully validated using established protocols.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • oscillometric deviceDevice

    The blood pressure will be measured by the Automatic blood pressure monitor(Oscillometric) named the OMRON M2 basic® device was provided by Omron Healthcare company.

    This monitor uses inflation by Fuzzy-Logic controlled by electric pump and an automatic rapid pressure release valve for the deflation , its cuff allows BP measurements in arm circumference of 22-42 cm. The device measure BP and pulse rate with a pressure range of 0-299 mmHg and pulse rate range of 40-180 beats/min.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Detection of kidney dysfunction in patients with primary hypertension

    Detection of kidney dysfunction by estimation of creatinine clearance using crclcockroftـGault equation.

    In patients with primary hypertension and blood pressure will measured by two methods

    1. Central Blood Pressure monitoring through non-invasively using a new well calibrated device named Mobil-O- Graph .( Cuff-based oscillometry at the brachial artery)
    2. Automatic blood pressure monitor (Oscillometric) named the OMRON M2 basic® device was provided by Omron Healthcare company.

    Measured: 1 year

Questions about this trial

What is this clinical trial studying?

An observational study of Primary Hypertension, run by Assiut University.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 11 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Nader Fawzy, MB Bch (00201200394430, nader.nabilfawzy87@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Detection of kidney dysfunction in patients with primary hypertension (time frame: 1 year). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT03491813, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Mar 2019.
