Inappropriate therapy of euvolemic hyponatremia, the most frequent type of hyponatremia in SARS-CoV-2 infection, is associated with increased mortality in COVID-19 patients.

Introduction: Admission hyponatremia, frequent in patients hospitalized for COVID-19, has been associated with increased mortality. However, although euvolemic hyponatremia secondary to the Syndrome of Inappropriate Antidiuresis (SIAD) is the single most common cause of hyponatremia in community-acquired pneumonia (CAP), a thorough and rigorous assessment of the volemia of hyponatremic COVID-19 subjects has yet to be described. We sought to identify factors contributing to mortality and hospital length-of-stay (LOS) in hospitalized COVID-19 patients admitted with hyponatremia, taking volemia into account. Method: Retrospective study of 247 patients admitted with COVID-19 to a tertiary hospital in Madrid, Spain from March 1st through March 30th, 2020, with a glycemia-corrected serum sodium level (SNa) < 135 mmol/L. Variables were collected at admission, at 2nd-3rd day of hospitalization, and ensuing days when hyponatremia persisted. Admission volemia (based on both physical and analytical parameters), therapy, and its adequacy as a function of volemia, were determined. Results: Age: 68 years [56-81]; 39.9% were female. Median admission SNa was 133 mmol/L [131- 134]. Hyponatremia was mild (SNa 131-134 mmol/L) in 188/247 (76%). Volemia was available in 208/247 patients; 57.2% were euvolemic and the rest (42.8%) hypovolemic. Hyponatremia was left untreated in 154/247 (62.3%) patients. Admission therapy was not concordant with volemia in 43/84 (51.2%). In fact, the majority of treated euvolemic patients received incorrect therapy with isotonic saline (37/41, 90.2%), whereas hypovolemics did not (p=0.001). The latter showed higher mortality rates than those receiving adequate or no therapy (36.7% vs. 19% respectively, p=0.023). The administration of isotonic saline to euvolemic hyponatremic subjects was independently associated with an elevation of in-hospital mortality (Odds Ratio: 3.877, 95%; Confidence Interval: 1.25-12.03). Conclusion: Hyponatremia in COVID-19 is predominantly euvolemic. Isotonic saline infusion therapy in euvolemic hyponatremic COVID-19 patients can lead to an increased mortality rate. Thus, an exhaustive and precise volemic assessment of the hyponatremic patient with CAP, particularly when due to COVID-19, is mandatory before instauration of therapy, even when hyponatremia is mild.

First survey on the diagnosis and treatment of primary aldosteronism by Spanish Endocrinology and Nutrition specialists.

OBJECTIVE: To evaluate the indication and the resources for the screening/diagnosis of primary aldosteronism (PA) in Endocrinology units in Spain. MATERIAL AND METHODS: An anonymous 2-phase (2020/2021) online survey was conducted by the AdrenoSEEN group among SEEN members with data about screening, confirmation tests, availability of catheterisation and the treatment of PA. RESULTS: Eighty-eight (88) specialists completed the survey. Plasma aldosterone concentration and plasma renin activity were available at all centres; urinary aldosterone was available in 55% of them. The most frequent indications for determining the aldosterone/renin ratio (ARR) were adrenal incidentaloma (82.6%), hypertension with hypokalaemia (82.6%), hypertension in patients <40 years (79.1%) and a family history of PA (77.9%). 61% and 18% of the respondents used an ARR cut-off value of PA of ≥30 and 20ng/dl per ng/mL/, respectively. The intravenous saline loading test was the most commonly used confirmatory test (66.3%), followed by the captopril challenge test (24.4%), with the 25mg dose used more than the 50mg dose (65% versus 35%). 67.4% of the participants confirmed the availability of adrenal vein catheterization (AVC). 41% of this subgroup perform it with a continuous infusion versus 30.5% with an ACTH (1-24) bolus, whereas 70.3% employ sequential adrenal vein catheterization. 48% of the participants reported an AVC success <50%. Total laparoscopic adrenalectomy was the treatment of choice (90.6%), performed by specialists in General and Digestive Surgery specialising in endocrinological pathology. CONCLUSION: PA screening and diagnostic tests are extensively available to Spanish endocrinologists. However, there is a major variability in their use and in the cut-off points of the diagnostic methods. The AVS procedure remains poorly standardised and is far from delivering optimal performance. Greater standardisation in the study and diagnosis of PA is called for.

Laparoscopic adrenalectomy vs. radiofrequency ablation for the treatment of primary aldosteronism. A single center retrospective cohort analysis adjusted with propensity score.

BACKGROUND: Laparoscopic adrenalectomy (LA) is the gold standard treatment for unilateral primary aldosteronism. However, satisfactory results have also been published with radiofrequency ablation (RFA). The aim of this study was to compare LA and RFA for the treatment of primary aldosteronism. METHODS: A retrospective cohort study of the patients who underwent LA or RFA in a single center was performed. Morbidity and long-term effectiveness (cure rate and blood pressure control) were analyzed. A multivariate analysis with a propensity score was also performed. RESULTS: Thirty-four patients were included in the study, 24 in the LA group and 10 in the RFA group. Hypertension had been diagnosed a median of 12 years before the intervention. Hypertension was properly controlled before the intervention in 55.9% of the patients. Hypertensive crisis was more common during RFA (4.2% vs. 70.0%, p < 0.001), although no patient suffered any complication because of these crises. LA was longer (174.6 vs. 105.5 min, p = 0.001) and had a longer length of stay (median 2 vs 1 days, p < 0.001). No severe complications were observed in any of the patients. After a median follow-up of 46.2 months, more patients had hypertension cured and blood pressure controlled in the LA group (29.2% vs. 0%, p = 0.078 and 95.5% vs. 50.0%, p = 0.006, respectively). Also, patients in the LA group were taking less antihypertensive drugs (1.8 vs. 3.0, p = 0.054) or mineralocorticoid receptor antagonists (41.7% vs. 90.0%, p = 0.020). Multivariate analysis adjusted by propensity score showed that LA had an OR = 11.3 (p = 0.138) for hypertension cure and an OR = 55.1 (p = 0.040) for blood pressure control. CONCLUSIONS: Although RFA was a less invasive procedure than LA, hypertension was cured and blood pressure was properly controlled in more patients from the LA group. Patients who underwent LA were taking less antihypertensive drugs than patients who had undergone RFA.

Evaluación psicosocial en adolescentes transgénero / Psychosocial assessment in transgender adolescents

OBJETIVOS: Evaluar el estado psicosocial de los pacientes que acudan a consulta de endocrinología pediátrica por incongruencia de género y determinar el impacto en este sentido de la terapia hormonal cruzada (THC) después de un año. MATERIAL Y MÉTODOS: Se trata de un estudio analítico, prospectivo realizado en adolescentes con incongruencia de género de entre 14 y 18 años que acuden a endocrinología infantil durante 2018-2019. Tamaño muestral: 23 casos transgénero (16 masculinos y 7 femeninos) y 30 controles cis. Variables del estudio en T0 (pretratamiento) y T1 (tras un año de THC): datos sociodemográficos, Test de Utrecht, Test SDQ-Cas, APGAR familiar, Escala STAI, Test de evaluación de depresión BDI-II. RESULTADOS: Se encuentra mejoría significativa (p < 0,05) entre T0 y T1 en el grupo trans en cuanto a los síntomas emocionales, los problemas de conducta, los síntomas de hiperactividad y la conducta prosocial, así como en el grado de ansiedad y depresión. Existen diferencias significativas entre el grupo trans y los controles en T0 igualándose las puntuaciones en T1 en las escalas evaluadas. Las familias de nuestra muestra de pacientes transgénero proporcionan un entorno muy favorable según las puntuaciones obtenidas en la escala del APGAR familiar. CONCLUSIONES: Los índices de ansiedad, distrés emocional y comportamental, sintomatología depresiva, así como el sentimiento de disforia de género de nuestra muestra de pacientes transgénero fueron similares a los de población no transexual de su misma edad tras un año de THC iniciada en edades comprendidas entre los 14-18 años

OBJECTIVES: To evaluate the psychosocial status of the patients who attend a paediatric endocrinology clinic due to gender incongruity (GI), and to establish the impact on this after one-year of cross hormonal therapy (CHT). MATERIAL AND METHODS: An analytical and prospective study conducted on adolescents between 14 and 18 years old with GI, and who attended the Endocrinology clinic during 2018-2019. The sample included 23 transgender cases (16 male and 7 female cases) and 30 cisgender controls. Study variables were collected at T0 (pre-treatment) and T1 (after one year of CHT) and included sociodemographic data, Utrecht test, SDQ-Cas test, family APGAR test, STAI scale-anxiety Grade, and BDI-II depression assessment test. RESULTS: A significant improvement (P < .05) was found between T0 and T1 in the transgender group in terms of emotional symptoms, behaviour problems, hyperactivity symptoms, pro-social conduct, as well as in the degree of anxiety and depression measured by the SDQ-Cas test, the STAI and the BDI-II scale. There were significant differences in these scales between the transgender group and the controls at T0, however, the scores equalised at T1. The families in this sample of transgender patients provided a very favourable environment according to the scores obtained on the family APGAR scale. CONCLUSIONS: The rates of anxiety, emotional and behaviour distress, depressive symptomatology, as well as the feeling of gender dysphoria of these transgender patients were similar to those of non-transsexual population of the same age after one year of CHT initiated at ages between 14-18 years old

Cardiometabolic profile of non-functioning and autonomous cortisol-secreting adrenal incidentalomas. Is the cardiometabolic risk similar or are there differences?

OBJECTIVE: To study the differences in the cardiometabolic profile between patients with non-functioning adrenal incidentalomas (NFAI) and incidentalomas with autonomous cortisol secretion (ACS). METHODS: A total of 149 patients with adrenal incidentalomas were retrospectively evaluated and followed-up for a mean time of 34.6 months at Departments of Endocrinology and Metabolic Diseases Units of four tertiary Spanish hospitals. Patients were grouped as NFAI or ACS adenomas based on two cutoffs in the dexamethasone suppression test (DST): 3.0 µg/dl (NFAIDST3 or ACSDST3) and 1.8 µg/dl (ACSDST1.8 and NFAIDST1.8). RESULTS: The mean age of both groups was 62.0 (10.31) and was similar in ACS and NFAI. The prevalence of diabetes, high blood pressure, cardiovascular, and cerebrovascular disease was higher in ACS than in NFAI, but differences only reached statistical significance for cerebrovascular disease using the 3.0 µg/dl cutoff (15.8% vs 2.3%, p = 0.01) and for diabetes using the 1.8 µg/dl cutoff (38.0% vs 22.0%, p = 0.04). No differences were found in the prevalence of dyslipidemia. The prevalence of obesity was lower in patients with ACS than in NFAI 26.3% vs 39.2%, p = 0.18 (NFAIDST3 vs ACSDST3) and 32.1% vs 40.6%, p = 0.56 (ACSDST1.8 vs NFAIDST1.8), but the differences did not reach statistical significance. Maximum adenoma diameter (R-squared = 0.15, p < 0.001) and cerebrovascular disease (OR = 1.59, p = 0.04) were the only parameters that could be predicted by the DST. The DST was an inadequate predictor of clinical (systolic and diastolic blood pressure, body mass index), hormonal (DHEAS, ACTH, UFC, and basal serum cortisol), biochemical (glucose, cholesterol, LDL, HDL, and triglycerides), and other radiological (laterality, lipid content) parameters. Throughout the follow-up, patients did not develop overt Cushing's Syndrome; three NFAIDST3 developed ACSDST3, eight NFAIDST1.8 developed ACSDST1.8, and one NFAIDST1.8 progressed to ACSDST3. In both groups (NFAI and ACS) the metabolic profile remained stable. CONCLUSIONS: Our data suggest higher prevalence of diabetes and cerebrovascular disease in ACS patients compared with NFAI. However, probably because of the small sample size, the differences only reached statistical significance using the cutoffs of 1.8 µg/dl for diabetes and 3.0 µg/dl for cerebrovascular disease. Patients with ACS and NFAI rarely progress to more aggressive forms of hypercortisolism, and the metabolic profile usually remains stable during the follow-up.

HELICOBACTER PYLORI (HP) INFECTION IN OBESE PATIENTS UNDERGOING ROUXEN- Y GASTRIC BYPASS; EFFICACY OF TWO DIFFERENT TREATMENT REGIMENS IN HP ERADICATION.

INTRODUCTION: the ultimate cause for the increased incidence of gastric ulcer following Roux-en-Y gastric bypass (RYGB) remains unclear. Treatment of HP infection is recommended before surgery in countries with high prevalence such as Spain in other to diminish the risk. However, the current regimens used might not be adequate in view of the high failure rate for HP eradication. METHODS: we reviewed 243 patients retrospectively undergoing RYGB and found 111 patients (45%) with HP infection. Therefore, we compared the eradication rate between 2 different regimens. RESULTS: 70 patients received OCA(Omeprazole:20 mg/12h, Clarithromycin 500 mg/12h and Amoxicillin 1 gram/12h for 10 days) while 41 patients received OLA (Omeprazole 20 mg/12 hours, Levofloxacin 500 mg/12hours and Amoxicillin 1 gram/12h for 10 days) for HP eradication. In 56/70 (80%) patients receiving OCA therapy HP was eradicated compared to 37/41 (91%) receiving OLA as first line therapy (p = 0.283). When used as second line therapy, in 13/14 (92%) patients receiving OLA HP was eradicated. CONCLUSION: clarithromycin resistance remains a matter of concern in this population while OLA seems to be a good alternative therapy for HP eradication, especially when OCA regimen fails.

Introducción: las causas implicadas en el aumento de incidencia de úlcera gástrica tras el bypass en Y de Roux no son completamente conocidas. El tratamiento de la infección por HP se recomienda antes de la cirugía en países cuya prevalencia sea elevada, como el caso de España, de cara a disminuir dicha complicación. Sin embargo, las pautas actuales de tratamiento pueden no ser adecuadas dados los elevados índices de resistencia. Pacientes y métodos: análisis retrospectivo de 243 pacientes operados de bypass en Y de Roux. De ellos, 111 pacientes (45%) presentaban infección por HP. Objetivo principal: comparación de la eficacia de dos terapias de erradicación de la infección por HP. Resultados: 70 pacientes recibieron OCA( Omeprazol 20 mg/12 h, Claritromicina 500 mg/12 h y Amoxicilina 1 g/12h durante 10 días), mientras que 41 pacientes recibieron OLA (Omeprazol 20 mg/12 h, Levofloxacino 500 mg/12 h y Amoxicilina 1 g/12 h durante 10 días). En 56/70 pacientes (80%) que recibieron OCA HP fue erradicado, comparado con 37/41 (91%) del grupo que recibió OLA como primera terapia (p = 0,283). La terapia con OLA usada de segunda línea fue eficaz en 13/14 pacientes con HP resistente a la terapia OCA. Conclusión: la resistencia de HP a Claritromicina es significativa en nuestra serie de pacientes, siendo la terapia con OLA una alternativa adecuada en las cepas resistentes.
