Trial summary

Primary aldosteronism (PA) is the excessive endogenous production of the mineralocorticoid aldosterone. Although various rare forms of PA exist, the vast majority of cases are accounted by either an aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia. Read more about this study

About this study

Official title: Characteristics Predicting Clinically Relevant Reduction of Hypertension Following Adrenalectomy for Primary Aldosteronism: a Multicenter Analysis

Primary aldosteronism (PA) is the excessive endogenous production of the mineralocorticoid aldosterone. Although various rare forms of PA exist, the vast majority of cases are accounted by either an aldosterone-producing adenoma (APA) or bilateral adrenal hyperplasia. During the last decades the prevalence of PA has risen, predominantly due to better awareness of disease. Several studies estimated a prevalence of PA up to 17% in an unselected population of hypertensive patients. However, in a population with resistant hypertension the reported prevalence is even higher: 17-23%. This emphasizes the clinical impact of PA on morbidity and mortality due to high blood pressure. Since both hypertension and aldosteronism are independent risk factors for cardiovascular morbidity, the aim of treatment is curation or reduction of both.

After an adrenalectomy for APA normalization of biochemical abnormalities is achieved in almost all cases. Nevertheless, curation of hypertension (systolic blood pressure <140 and diastolic blood pressure <90 mmHg) without the need of antihypertensive medication is accomplished in only 35-45% of the cases. In 2008 the Aldosteronoma Resolution Score (ARS) was developed. This score predicts the likelihood of complete resolution of the hypertension in patients with an aldosteronoma and has been validated by other investigator groups.

Reduction of hypertension is also an important clinical outcome and is reported in 90-98% of the patients after surgery. In most studies reduction is defined as a certain decrease in blood pressure or antihypertensive medication. However, there is no consensus on the precise definition of reduction in these patients, which leads to incomparable results.

The aim of the proposed study is to determine the proportion of patients with clinically relevant reduction of hypertension after adrenalectomy in a large cohort. Furthermore, the investigators aim to determine the characteristics predicting this clinically relevant reduction. Additionally, the investigators evaluate the predictive value of the Aldosteronoma Resolution Score for clinically relevant reduction and aim to develop a scoring system to help clinicians predict the likelihood of reduction of hypertension after adrenalectomy so it can be used for patient counseling.

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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Postoperative blood pressure measurement (time frame: 6 months postoperative). The study lists 3 primary outcomes in all. 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 NCT04761354, which also lists 9 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 18 Feb 2021.
