The prevalence of primary and secondary hyperparathyroidism and its cardiometabolic implications in primary aldosteronism.

BACKGROUND: The aim of this study was to analyze the prevalence of primary and secondary hyperparathyroidism in patients with primary aldosteronism (PA), and its implication on cardiovascular and metabolic outcomes. METHODS: A retrospective study of patients with PA (exposed cohort, N.=44) and all hypertensive (EH) patients with adrenal lesions without PA nor other adrenal hypersecretion (non-exposed cohort, N.=41) on follow-up at our center between 2016 and 2020. RESULTS: The mean age of patients with PA and EH was 55.1±14.13 and 66.3±10.93 (P<0.001), and 50% of PA and 39.0% of EH were women (P=0.309). At diagnosis, the prevalence of primary hyperparathyroidism in PA was of 18.2%, and all were normocalcemic hyperparathyroidism cases. Globally, no differences were found in the prevalence of primary hyperparathyroidism compared to EH (18.2% vs. 29.3%, P=0.229), but hypercalcemic primary hyperparathyroidism was significantly more prevalent in EH patients than in PA (22.0% vs. 0%, P=0.001). There were 47.7% (N.=21) cases of secondary hyperparathyroidism in patients with PA (4 due to chronic kidney disease (CKD) and vitamin D deficiency, and 17 due to vitamin D deficiency alone). The cardiometabolic profile of patients with PA and hyperparathyroidism (N.=29) was similar to of those patients without hyperparathyroidism (N.=15) at diagnosis and after a median follow-up of 3.6 years (interquartile range 1.1-5.9). CONCLUSIONS: Although primary and secondary hyperparathyroidism are common in patients with PA, their prevalence was similar than the observed in EH patients. Primary hyperparathyroidism is usually mild in PA, appearing as normocalcemic forms. No negative implications of the hyperparathyroidism in the cardiometabolic profile of PA were observed.

Riesgo cardiometabólico en pacientes con hiperaldosteronismo primario y secreción autónoma de cortisol. Estudio de casos y controles / Cardiometabolic risk in patients with primary aldosteronism and autonomous cortisol secretion. Case-control study

Objetivo: Analizar las diferencias en el perfil cardiometabólico de los pacientes con hiperaldosteronismo primario (HAP) y secreción autónoma de cortisol (SAC), emparejados por edad y sexo.MétodosEstudio de casos y controles; casos de HAP sin SAC asociada y como controles, pacientes con SAC (test de supresión de dexametasona ≥ 1.8 μg/dL en ausencia de datos específicos de hipercortisolismo), emparejados por edad y sexo. Se analizaron las comorbilidades HTA, diabetes, obesidad, dislipemia, insuficiencia renal crónica y eventos cardiovasculares y cerebrovasculares, así como su grado de control.ResultadosSe incluyeron 57 pacientes con HAP y 57 con SAC. Al diagnóstico, aparte de una mayor prevalencia de HTA en los pacientes con HAP (100 vs. 52,7%, p < 0,0001) y niveles más altos de TAS (143,2 [2,5] vs. 135,3 [2,6] mmHg, p = 0,032) que en SAC, no se detectaron diferencias en la prevalencia de otras comorbilidades. No obstante, los pacientes con SAC presentaban cifras más elevadas de HbA1c (p = 0,028).Tras una mediana de seguimiento de 2,25 años, los pacientes con HAP presentaron un mayor deterioro de la función renal (descenso medio del filtrado glomerular [MDRD-4] -17,4 [3] vs. -2,3 [4,4] mL/min/1,73 m2, p = 0,005) y del perfil lipídico (Δtriglicéridos de 34,5 [15,8] vs. -6,7 [11,3] mg/dL, p = 0,038) que los SAC.ConclusionesA pesar la mayor prevalencia de HTA en los pacientes con HAP que con SAC, emparejados por edad y sexo, no se detectaron diferencias en la prevalencia de otras comorbilidades cardiometabólicas. No obstante, los HAP presentaron un mayor deterioro de la función renal y del perfil lipídico a lo largo del seguimiento que el grupo de SAC. (AU)

Objective: To analyse the differences in the cardio-metabolic profile of patients with primary aldosteronism (PA) and autonomous cortisol secretion (ACS) matched by age and sex.MethodsCase-control study; cases of PA without associated ACS and as controls patients with ACS (dexamethasone suppression test ≥ 1.8 μg/dL in the absence of specific hypercortisolism clinical data), matched by age and sex. Comorbidities of hypertension, diabetes, obesity, dyslipidaemia, chronic kidney failure, and cardiovascular and cerebrovascular events were analysed, as well as their degree of control.Results57 patients with PA and 57 with ACS were included. On diagnosis, in addition to a higher prevalence of hypertension in the PA patients (100 vs. 52.7%, p < .0001) and higher systolic blood pressure levels (143.2 (2.5) vs. 135.3 (2.6) mmHg, p = .032) than in the ACS patients, no other differences were detected in the prevalence of other cardio-metabolic comorbidities. Nevertheless, the patients with ACS had higher HbA1c levels (p = .028) than the PA patients.After a median follow-up of 2.25 years, the patients with PA presented a greater deterioration in kidney function (Average decrease in glomerular filtration rate (MDRD-4) -17.4 (3.0) vs. -2.3 (4.4) mL/min/1.73 m2, p = .005) and lipid profile (Δtriglycerides of 34.5 (15.8) vs. -6.7 (11.3) mg/dL, p = .038) than the ACS patients.ConclusionsDespite the higher prevalence of hypertension in the patients with PA than in the patients with ACS matched by age and sex, no differences were detected in the prevalence of other cardio-metabolic comorbidities. However, the PA patients showed a greater deterioration in kidney function and lipid profile throughout the follow-up than the ACS patients. (AU)

Higher risk of chronic kidney disease and progressive kidney function impairment in primary aldosteronism than in essential hypertension. Case-control study.

PURPOSE: To study the differences in the prevalence, risk, and grade of control of different cardiometabolic comorbidities in patients with primary aldosteronism (PA) and essential hypertension (EH) matched by age, sex, and blood pressure levels at diagnosis. METHODS: Case-control study of a secondary base (PA patients in follow-up in a tertiary hospital between 2018 and 2020). Controls were patients with non-functioning adrenal incidentalomas and EH, matched by age, sex, and baseline diastolic blood pressure (DBP) and systolic blood pressure (SBP). RESULTS: Fifty patients with PA and 50 controls were enrolled in the study. At diagnosis, PA patients had a higher prevalence of chronic kidney disease (CKD) than controls (18.4% vs. 2.1%, P = 0.008). No differences were detected in the prevalence of other cardiometabolic comorbidities nor in their degree of control (P > 0.05). All patients received antihypertensive medical treatment and 10 PA patients underwent unilateral laparoscopic adrenalectomy. After a median follow-up of 31.9 [IQR = 1.0-254.8] months, PA patients presented a greater degree of declination of kidney function than controls (average decrease in glomerular filtration rate (MDRD-4) -17.6 ± 3.1 vs. -2.8 ± 1.8 ml/min/1.73 m2, P < 0.001). There were no differences in the grade of SBP (P = 0.840) and DBP control (P = 0.191), nor in the risk of developing other comorbidities or in their degree of control. CONCLUSIONS: PA patients have a higher prevalence of CKD at the time of diagnosis when compared to EH matched by age, sex, and blood pressure levels. Furthermore, the risk of kidney function impairment throughout the follow-up is significantly greater in PA patients and is independent of the degree of blood pressure control.
