Abstract
AbstractBackgroundUnilateral primary aldosteronism (UPA) is the most frequent surgically curable form of endocrine hypertension. Adrenalectomy is the cornerstone of treatment for UPA, but outcomes after surgery are variable. Aldosteronoma Resolution Score (ARS) is a four‐item predictive score for the cure of hypertension after adrenalectomy for UPA and has been demonstrated to be valid in different populations. We aimed in this study to validate the accuracy of this score in a North‐African population.MethodsBetween 2000 and 2021, the charts of 71 Tunisian patients who underwent laparoscopic adrenalectomy for UPA were retrospectively reviewed. Postoperative outcomes were assessed using the primary aldosteronism surgical outcome (PASO) criterion. The accuracy of the ARS was determined retrospectively by receiver operating characteristic curve and area under the curve.ResultsThirty‐four patients (48%) had complete clinical success according to the PASO criteria. Multivariate regression analysis revealed that the main determinants of complete clinical success were the absence of diabetes (OR: 5.205), a BMI <30 (OR: 4.930), a number of antihypertensive medications ≤2 (OR: 8.667), a plasma ARR >332 (OR: 4.554) and an ARS score ≥3 (OR: 2.056). Cure rates were, respectively, 21.1, 51.6, and 66.6% for patients with a score ARS 0–1, 2–3, and 4–5. The AUC of the ARS was 0.837.ConclusionThe ARS is a sufficiently predictive score in our North‐African population. It may be used preoperatively to predict the outcome after adrenalectomy in these populations.
