Indicación, realización y resultado del cateterismo de venas adrenales en pacientes con hiperaldosteronismo primario / Indication, performance and outcomes of adrenal vein sampling in patients with primary hyperaldosteronism

El hiperaldosteronismo primario (HAP) es una causa importante de hipertensión arterial (HTA) secundaria. El estudio del mismo precisa de una alta sospecha clínica, además de un estudio hormonal que confirme la hipersecreción hormonal. Es importante iniciar el tratamiento adecuado una vez se confirma el diagnóstico, y para ello es preciso demostrar si la hipersecreción hormonal es unilateral (pacientes que podrían ser tributarios a tratamiento quirúrgico) o bilateral (pacientes que son tributarios a tratamiento únicamente farmacológico). En el Hospital del Mar desde el año 2016 existe un equipo de trabajo multidisciplinar en el que participan nefrólogos, endocrinólogos, radiólogos y cirujanos para evaluar los casos con sospecha de hiperaldosteronismo y consensuar el mejor abordaje diagnóstico-terapéutico de estos pacientes, incluyendo la necesidad de cateterismo venoso adrenal, que es una técnica que en los últimos años se ha erigido como gold standard para el estudio del HAP. En el presente estudio recogemos la experiencia de nuestro centro en la realización de cateterismo venoso adrenal y en la utilidad de este para el manejo de tales pacientes (AU)

Primary hyperaldosteronism (PAH) is an important cause of secondary hypertension (HTN). The study of the same requires a high clinical suspicion in addition to a hormonal study that confirms hormonal hypersecretion. It is important to start the appropriate treatment once the diagnosis is confirmed, and for this is necessary to demonstrate whether the hormonal hypersecretion is unilateral (patients who could be candidates for surgical treatment) or bilateral (patients who are candidates for pharmacological treatment only). At the Hospital del Mar since 2016 there has been a multidisciplinary work team in which Nephrologists, Endocrinologists, Radiologists and Surgeons participate to evaluate cases with suspected hyperaldosteronism and agree on the best diagnostic-therapeutic approach for these patients, including the need for adrenal vein sampling, which is a technique that in recent years has become the gold standard for the study of PAH. In the present study we collect the experience of our center in performing adrenal vein catheterization and its usefulness for the management of these patients (AU)

Telehealth model versus in-person standard care for persons with type 1 diabetes treated with multiple daily injections: an open-label randomized controlled trial.

Objective: Increasing evidence indicates that the telehealth (TH) model is noninferior to the in-person approach regarding metabolic control in type 1 diabetes (T1D) and offers advantages such as a decrease in travel time and increased accessibility for shorter/frequent visits. The primary aim of this study was to compare the change in glycated hemoglobin (HbA1c) at 6 months in T1D care in a rural area between TH and in-person visits. Research design and methods: Randomized controlled, open-label, parallel-arm study among adults with T1D. Participants were submitted to in-person visits at baseline and at months 3 and 6 (conventional group) or teleconsultation in months 1 to 4 plus 2 in-person visits (baseline and 6 months) (TH group). Mixed effects models estimated differences in HbA1c changes. Results: Fifty-five participants were included (29 conventional/26 TH). No significant differences in HbA1c between groups were found. Significant improvement in time in range (5.40, 95% confidence interval (CI): 0.43-10.38; p < 0.05) and in time above range (-6.34, 95% CI: -12.13- -0.55;p < 0.05) in the TH group and an improvement in the Diabetes Quality of Life questionnaire (EsDQoL) score (-7.65, 95% CI: -14.67 - -0.63; p < 0.05) were observed. In TH, the costs for the participants were lower. Conclusions: The TH model is comparable to in-person visits regarding HbA1c levels at the 6-month follow-up, with significant improvement in some glucose metrics and health-related quality of life. Further studies are necessary to evaluate a more efficient timing of the TH visits.

Contribution of cardio-vascular risk factors to depressive status in the PREDIMED-PLUS Trial. A cross-sectional and a 2-year longitudinal study.

BACKGROUND: Cardio-vascular disease and depression are thought to be closely related, due to shared risk factors. The aim of the study was to determine the association between cardio-vascular risk (CVR) factors and depressive status in a population (55-75 years) with metabolic syndrome (MetS) from the PREDIMED-Plus trial. METHODS AND FINDINGS: Participants were classified into three groups of CVR according to the Framingham-based REGICOR function: (1) low (LR), (2) medium (MR) or (3) high/very high (HR). The Beck Depression Inventory-II (BDI-II) was used to assess depressive symptoms at baseline and after 2 years. The association between CVR and depressive status at baseline (n = 6545), and their changes after 2 years (n = 4566) were evaluated through multivariable regression models (logistic and linear models). HR women showed higher odds of depressive status than LR [OR (95% CI) = 1.78 (1.26, 2.50)]. MR and HR participants with total cholesterol <160 mg/mL showed higher odds of depression than LR [OR (95% CI) = 1.77 (1.13, 2.77) and 2.83 (1.25, 6.42) respectively)] but those with total cholesterol ≥280 mg/mL showed lower odds of depression than LR [OR (95% CI) = 0.26 (0.07, 0.98) and 0.23 (0.05, 0.95), respectively]. All participants decreased their BDI-II score after 2 years, being the decrease smaller in MR and HR diabetic compared to LR [adjusted mean±SE = -0.52±0.20, -0.41±0.27 and -1.25±0.31 respectively). MR and HR participants with total cholesterol between 240-279 mg/mL showed greater decreases in the BDI-II score compared to LR (adjusted mean±SE = -0.83±0.37, -0.77±0.64 and 0.97±0.52 respectively). CONCLUSIONS: Improving cardiovascular health could prevent the onset of depression in the elderly. Diabetes and total cholesterol in individuals at high CVR, may play a specific role in the precise response. International Standard Randomized Controlled Trial (ISRCTN89898870).

Ethnic differences in the impact of gestational diabetes on macrosomia.

BACKGROUND: Previous studies reported an ethnic disparity in gestational diabetes mellitus-associated birth outcomes, with some suggesting that macrosomia increases to a lesser extent in groups at high risk, the opposite of the pattern observed by others. Our aim was to evaluate ethnic variation in the impact of gestational diabetes mellitus (GDM). METHODS: A case-control study evaluating pregnancy outcomes was conducted in women with and without GDM from five ethnic groups. Data on GDM were collected between January 2004 and July 2017. Women giving birth between May 2013 and July 2017 in whom pre-existing diabetes had been ruled out served as controls. A multivariate logistic regression analysis was performed to determine factors independently associated with macrosomia. RESULTS: Overall, 852 GDM women and 3,803 controls were included. In Caucasian and East-Asian women excessive gestational weight gain (OR 2.273, 95% CI 1.364-3.788 and OR 3.776, 95% CI 0.958-14.886) was an independent predictor of macrosomia. In Latin-American and Moroccan women, obesity (OR 1.774, 95% CI 1.219-2.581 and OR 1.656, 95% CI 1.054-2.601), GDM (OR 2.440; 95% CI 1.048-5.679 and OR 3.249, 95% CI 1.269-8.321) and gestational weight gain but only for Latin-American women (OR 2.365, 95% CI 1.039-5.384) were associated with macrosomia. In South-Central Asian women, only GDM was associated with macrosomia (OR 3.701, 95% CI 1.437-9.532). CONCLUSIONS: GDM is an independent predictor of macrosomia in Latin-American, South-Central Asian and Moroccan women but not in Caucasian or East-Asian women in whom other factors play a more important role.

Is fasting plasma glucose in early pregnancy a better predictor of adverse obstetric outcomes than glycated haemoglobin?

OBJECTIVES: To determine, in a multi-ethnic cohort, the suitability of first-trimester fasting plasma glucose and HbA1c levels in non-diabetic range to identify women without diabetes at increased pregnancy risk. STUDY DESIGN: A retrospective analysis of a prospective cohort between April 2013 and September 2015. Universal testing for fasting plasma glucose and HbA1c levels at the first antenatal blood sampling was performed and women were screened for gestational diabetes mellitus at 24-28 weeks' gestation. Primary outcomes were macrosomia and pre-eclampsia, and secondary outcomes preterm delivery, Caesarean section and large-for-gestational age. Different fasting plasma glucose and HbA1c cut-off levels were assessed for associations with outcomes. RESULTS: 1,228 pregnancies were included for outcome analysis. After adjustment for potential confounders, no association was found between fasting plasma glucose levels and pregnancy outcomes. Women with an HbA1c ≥5.8% (39.9 mmol/mol) showed an increased risk of macrosomia (OR 2.69, 95% CI 1.16-6.24); an HbA1c ≥5.9% (41 mmol/mol) threshold was independently associated with a three-fold risk of pre-eclampsia (95% CI 1.03-9.9) and an HbA1c ≥6.0% (42.1 mmol/mol) with a four-fold risk of large-for-gestational age (95% CI 1.49-11.07). CONCLUSIONS: In a multi-ethnic population, first-trimester fasting plasma glucose levels were not a better predictor of pregnancy complications than HbA1c. Further, an early HbA1c ≥5.8% (39.9 mmol/mol) threshold is already associated with an increased risk of macrosomia.

La diabetes mellitus como factor protector del aneurisma de aorta abdominal: posibles mecanismos / Diabetes mellitus as a protective factor of abdominal aortic aneurysm: Possible mechanisms

El aneurisma de aorta abdominal (AAA) comparte diversos factores de riesgo con la aterosclerosis. De entre estos la diabetes mellitus (DM) podría tener un efecto negativo en la formación, crecimiento y expansión del AAA. En este sentido, diversas revisiones sistemáticas y metaanálisis publicados hasta 2016 han mostrado resultados concordantes en cuanto al posible efecto protector de la DM en la formación y progresión del AAA. No obstante, los mecanismos fisiopatológicos de esta supuesta protección son aún desconocidos. Parece que tanto la hiperglucemia como la hiperinsulinemia asociadas a la DM, al causar un incremento de los productos de glicación avanzada, una disminución de la fibrinólisis y alteraciones en las células musculares lisas, comportarían un menor riesgo de expansión aneurismática. Se considera que este papel protector está principalmente mediado por una disminución de las metaloproteasas, en concreto la tipo 2 y 9. Además, los fármacos utilizados en el tratamiento tanto de la DM tipo 2 como de la hipertensión arterial y la dislipidemia también podrían desempeñar un papel en este efecto protector. La metformina, las tiazolidinedionas, los inhibidores del DPP4, las estatinas y los inhibidores de la enzima conversora de la angiotensina han sido evaluados en este sentido. En conclusión, los estudios publicados hasta el momento parecen confirmar el efecto protector de la DM en la formación y expansión del AAA, aunque son necesarios futuros estudios a largo plazo para confirmar los mecanismos fisiopatológicos implicados, así como el papel de la medicación concomitante

Abdominal aortic aneurysm (AAA) shares several risk factors with atherosclerosis. Among these, diabetes mellitus (DM) could have a negative effect on the formation, growth and expansion of AAA. Several systematic reviews and meta-analyses reported up to 2016 have shown concordant results regarding the possible protective effect on AAA formation. However, the pathophysiological mechanisms of this supposed protective effect are still unknown. It appears that both hyperglycaemia and hyperinsulinemia, which are closely associated with DM, cause an increase in advanced glycation end-products, a decrease in fibrinolysis, and alterations in smooth muscle cells, leading to a decreased risk of aneurysm growth and expansion. This protective role is mainly mediated by a decrease in metalloproteinases, mainly type 2 and 9. In addition, drugs used to treat type 2 DM, as well as those for hypertension and dyslipidaemia could also play an important role in this protective effect. Metformin, thiazolidinediones, DPP4 inhibitors, statins, and angiotensin-converting enzyme inhibitors have been evaluated in this field. In conclusion, studies reported so far seem to confirm the protective effect of DM in both the formation and expansion of AAA, although future long-term studies are needed to confirm the pathophysiological mechanisms involved, as well as the role of concomitant medication

Previous Gestational Diabetes Increases Atherogenic Dyslipidemia in Subsequent Pregnancy and Postpartum.

In a cohort of women with previous gestational diabetes mellitus (GDM), we aimed to ascertain whether women with abnormal glucose tolerance 1-year postdelivery had a more atherogenic lipid profile during and after pregnancy than those with normal glucose tolerance. A prospective cohort study with longitudinal design between January 2004 and March 2016 was conducted. Three hundred and six (56.8%) of 537 women diagnosed with GDM during the studied period attended a control visit during the first year after delivery. Of these, 112 (36.6%) had prediabetes and 16 (5.2%) had type 2 diabetes mellitus. No significant differences during pregnancy were found in total, low-density lipoprotein, high-density lipoprotein (HDL) cholesterol, and triacylglycerol (TAG) concentrations among the three groups. Only HDL cholesterol and TAG levels differed significantly among groups at 2 and 12 months after delivery. Logistic regression analysis revealed pregnancy HDL and glucose metabolism status to be associated with the HDL cholesterol concentration 1-year postdelivery. Furthermore, the only independent factor associated with TAG levels 1 year after delivery was the gestational TAG concentration. In summary, an overweight multiethnic group of women with prior GDM presented a high incidence of postpartum dysglycemia (41.8%). HDL-cholesterol and TAG levels, both components of the metabolic syndrome, differed significantly among the three study groups in the glucose-metabolism status at 2 and 12 months after delivery. Women with previous GDM must be followed up in the postpartum period for early detection and management of lipid and glucose disorders.

Is first-trimester HbA1c useful in the diagnosis of gestational diabetes?

AIMS: To evaluate the usefulness and efficacy of first-trimester HbA1c in the diagnosis of gestational diabetes (GDM). METHODS: Prospective observational of consecutive pregnant women. All women had a first-trimester HbA1c determination and GDM screening at 24-28weeks of pregnancy using a two-step approach. A ROC curve was drawn to determine the sensitivity and specificity of HbA1c in detecting GDM and a rule-in rule-out diagnostic algorithm was proposed. The cost of the proposed algorithm was calculated. RESULTS: 152 (13.1%) of 1195 women were diagnosed of GDM. The area under the ROC curve for HbA1c to detect GDM was 0.679 (95%CI 0.631-0.727). A rule-out threshold for HbA1c of 4.8% (29mmol/mol) had 96.7% sensitivity (95%CI 93.9-99.5), 10.1% specificity (95%CI 8.3-12.0) and a negative predictive value of 95.3% (95%CI 91.3-99.3). A rule-in value of 5.6% (38mmol/mol) had a positive predictive value of 31.6% (95%CI 24.4-38.9), 89.3% specificity (95%CI 87.4-91.2) and 32.9% sensitivity (95%CI 25.4-40.4). The low positive predictive value of the rule-in threshold precludes its use for GDM diagnosis, but could be used to identify women at high risk of GDM in whom the diagnosis can be established using a one-step approach. The overall saving of the proposed algorithm would be 6.5% of the total cost with the standard strategy. CONCLUSIONS: A first-trimester HbA1c does not have sufficient sensitivity or specificity to diagnose GDM, although the use of a higher and lower threshold could simplify the diagnostic process by reducing the number of oral glucose tolerance test, associated costs and patient inconvenience.

Atherogenic Dyslipidemia Remission 1 Year After Bariatric Surgery.

PURPOSE: Given the lack of evidence of the effect of bariatric surgery (BS) on atherogenic dyslipidemia (AD), which is a characteristic of obese subjects, this study aimed to describe the remission rate of AD 1 year after BS in severely obese patients. MATERIALS AND METHODS: A non-randomised, prospective cohort study was conducted in patients undergoing laparoscopic Roux-en-Y gastric bypass or laparoscopic sleeve gastrectomy with a 1-year follow-up. AD was defined as triglycerides ≥1.71 mmol/l or treatment with fibrates and low high-density lipoprotein (HDL) cholesterol (<1.03 mmol/l in men or <1.3 mmol/l in women). RESULTS: AD was present in 81 (22.8%) of the 356 patients; these were more frequently men and presented higher total cholesterol and non-HDL cholesterol concentrations. AD remission rate was 74.1% at 3 months, 90.1% at 6 months and 96.3% at 12 months, respectively, after BS. In this group of patients, HDL cholesterol levels rose progressively (1.0 ± 0.2 to 1.5 ± 0.3 mmol/l, p < 0.001) and triglycerides decreased (2.5 ± 0.9 to 1.2 ± 0.5 mmol/l, p < 0.001) during follow-up. Regarding previous lipid-lowering therapy, fibrates and ezetimibe were withdrawn in all patients and statins in 69.4% 1 year after surgery. CONCLUSION: BS has beneficial effects on lipid profile, achieving complete remission of AD at 1 year of follow-up in almost all patients.

Hypertriglyceridemic waist in type 1 diabetes patients: prevalence and related factors.

BACKGROUND: The hypertriglyceridemic waist has been linked to a higher number of cardiovascular risk factors and a greater probability of developing diabetes and cardiovascular disease. Around 50% of individuals with type 1 diabetes (T1D) are overweight or obese and triglyceridemia is associated with the onset of micro- and macrovascular complications. METHODS: A cross-sectional study was conducted in men with T1D to assess the association between the prevalence of hypertriglyceridemic waist and cardiovascular risk factors and hypogonadism. Triglyceride levels + abdominal circumference taken together were stratified into quartiles to identify the hypertriglyceridemic waist phenotype. RESULTS: One hundred and eighty-one male patients were included. An increased prevalence of hypogonadism and hypertension in parallel to increased triglyceride + waist circumference quartile was observed. Patients in the highest quartile had higher insulin resistance measured by estimated glucose disposal rate (eGDR 7.8±2.1 mg/kg-1.min-1 in 1st quartile vs. 5.8±1.8 mg/kg-1.min-1 in 4th quartile, P=0.000), insulin requirements, hip circumference, percentage of fat mass, glycosilated hemoglobin and total and LDL cholesterol as well as lower levels of total testosterone (27.24±9.3 nmol/L in 1st quartile vs. 17.4±8 nmol/L in 4th quartile, P=0.000) and HDL cholesterol. An inverse relationship was found between triglycerides + waist circumference and total testosterone levels (R=-0.367, P<0.0001). CONCLUSIONS: The hypertriglyceridemic waist in men with T1D is associated with an atherogenic lipid profile, hypertension, worse metabolic diabetes control, increased insulin resistance and a higher prevalence of hypogonadism.

Severity of statin-induced adverse effects on muscle and associated conditions: data from the DAMA study.

BACKGROUND: Statins are generally well tolerated, but muscular adverse effects appear to be the most common obstacle limiting their use. Our objective was to describe the severity of muscle injury (myalgia, myositis and rhabdomyolysis) and associated conditions related to statin therapy that may be clinically significant. METHODS: A cross-sectional one-visit, non-interventional, national multicenter study including patients of both sexes over 18 years of age referred for past or present muscle symptoms associated with statin therapy was conducted. Clinical, biochemical and drug therapy characteristics were obtained at the initial evaluation. RESULTS: 3,845 patients were recruited from a one-day record from 2,001 physicians. Myalgia was present in 78.2% of patients, myositis in 19.3% and rhabdomyolysis in 2.5%. The prevalence of different comorbidities such as diabetes, hypertension, atrial fibrillation, and coronary heart disease increased as the severity of myopathy rose. High-intensity statin therapy was used in 33.4% of patients. Concomitant drugs metabolized by the CYP450 3A4 pathway were taken by 9.3% of patients, and statins with this metabolic route by 75%. Independent variables associated with myositis or rhabdomyolysis compared with myalgia alone in the multivariate model were excessive alcohol consumption and pravastatin therapy. CONCLUSION: Myalgia was the most common muscle adverse effect associated with statin therapy. Excessive alcohol consumption and pravastatin were independently associated with myositis or rhabdomyolysis.

Testosterone undecanoate improves lipid profile in patients with type 1 diabetes and hypogonadotrophic hypogonadism.

Testosterone deficiency (Td) has been associated with the metabolic syndrome. Few studies have evaluated this condition in type 1 diabetes (T1D). The primary aim of this study was to evaluate the effectiveness of testosterone undecanoate (TU) on insulin sensitivity, glycemic control, anthropometric parameters, blood pressure and lipid profile in patients with Td and T1D. We performed a randomized placebo-controlled multicenter study. INCLUSION CRITERIA: a) age ≥ 18 years; b) autoimmune diabetes; c) Td (total testosterone <10 nmol/L or calculated free testosterone <225 pmol/L and low/normal LH; d) ability to sign informed consent; e) comply with the study protocol. EXCLUSION CRITERIA: a) pituitary tumor, empty sella, hyperprolactinemia, panhypopituitarism or secondary hypogonadism; b) contraindications for treatment with testosterone undecanoate (TU); c) patients who did not agree to sign their informed consent. Six patients were randomly assigned to testosterone undecanoate (TU) treatment and 7 to placebo with the following dosing schedule: baseline, 6 weeks and 16 weeks. Blood test, anthropometric parameters, blood pressure and insulin sensitivity were determined at baseline, 6, 16 and 22 weeks. No differences were observed regarding insulin sensitivity, HbA1c or basal glucose, anthropometric parameters or blood pressure. At 22 weeks, the decrease in total cholesterol was 37.4 ± 27.5 mg/dL in the TU group compared with an increase of 13.2 ± 17.8 mg/dL in the placebo group (P<0.005), and LDL cholesterol concentration decreased 30.2 ± 22.1 mg/dL, compared with an increase of 10.5 ± 13.4 mg/dL in the placebo group (P=0.004). We conclude that treatment with TU in patients with T1D and Td improves lipid profile, with no effects on metabolic control or anthropometric parameters.

La prevención cardiovascular en la diabetes mellitus: un reto multifactorial / Cardiovascular prevention in diabetes mellitus: A multifactorial challenge

Los pacientes con diabetes mellitus tipo 2 son de alto/muy alto riesgo cardiovascular y comúnmente presentan otros factores de riesgo asociados, como la hipertensión, la obesidad y la dislipidemia. La enfermedad cardiovascular es la principal causa de morbimortalidad en esta población. Es fundamental el control integral de todos los factores de riesgo en los pacientes con diabetes para conseguir minimizar el riesgo de complicaciones macrovasculares. Dados los beneficios de las estrategias de intervención multifactorial en la prevención cardiovascular de los pacientes diabéticos, se revisan de forma individualizada los objetivos terapéuticos establecidos para cada factor de riesgo en la diabetes y los beneficios de su control

Patients with type 2 diabetes mellitus have a high to very high cardiovascular risk, and often have other associated risk factors, such as hypertension, obesity and dyslipidaemia. Cardiovascular disease is the leading cause of morbidity and mortality in this population. An integrated control of all risk factors in patients with diabetes is essential for minimising the risk of macrovascular complications. Given the benefits of the multifactorial intervention strategies for cardiovascular prevention in diabetic patients, a review is presented on the therapeutic goals established for each risk factor in diabetes and the benefits of their control

Déficit de testosterona, síndrome metabólico y diabetes mellitus / Testosterone deficiency, metabolic syndrome and diabetes mellitus

El déficit de testosterona en la edad adulta se relaciona con depresión, disminución de la libido, energía, hematocrito, masa muscular y de la densidad mineral ósea. En los últimos años, también se ha asociado con diversos componentes del síndrome metabólico, que a su vez se relacionan con un aumento de hasta 5 veces en el riesgo de enfermedad cardiovascular. Así, las concentraciones bajas de testosterona se asocian con una mayor resistencia a la insulina, incremento de la masa grasa, colesterol HDL bajo, triglicéridos elevados e hipertensión arterial. Inversamente, el tratamiento sustitutivo en pacientes con déficit de testosterona y diabetes mellitus tipo 2 y/o síndrome metabólico ha demostrado reducciones en la resistencia a la insulina, colesterol total, LDL y triglicéridos, y una mejoría del control glucémico y los parámetros antropométricos (AU)

Testosterone deficiency in adult age is associated with a decrease in libido, energy, hematocrit, muscle mass and bone mineral density, as well as with depression. More recently, testosterone deficiency has also been associated with various components of the metabolic syndrome, which in turn is associated with a five-fold increase in the risk of cardiovascular disease. Low testosterone levels are associated with increased insulin resistance, increase in fat mass, low HDL cholesterol, higher triglyceride levels and hypertension. Testosterone replacement therapy in patients with testosterone deficiency and type 2 diabetes mellitus and/or metabolic syndrome has shown reductions in insulin resistance, total cholesterol, LDL cholesterol and triglycerides and improvement in glycemic control and anthropometric parameters (AU)

Predictors of Hypertension Remission and Recurrence After Bariatric Surgery.

BACKGROUND: Few data exist on factors associated with hypertension (HTN) remission post-bariatric surgery. No information on factors that may predict HTN relapse is available. The aims were to assess the HTN remission and relapse rates at 1 and 3 years, respectively, post-bariatric surgery, and determine predictive factors. METHODS: A nonrandomized prospective cohort study on severely obese patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) with a follow-up of 36 months was conducted between 2005 and 2011. Criteria for HTN diagnosis were current treatment with antihypertensive agents and/or systolic blood pressure (BP) >140 mm Hg and/or diastolic BP >90 mm Hg. HTN remission was defined as normalization of BP maintained after discontinuation of medical treatment. RESULTS: A total of 197 patients were included in the study. HTN was present in 47.7%; 68.1% of hypertensive patients showed HTN remission 1 year after the surgical procedure, 21.9% of whom had relapsed at 3 years. The number of antihypertensive drugs prior to surgery was associated with a lower remission rate at the first year and a higher recurrence at 3 years. However, a smaller weight loss during the first year was associated with increased HTN recurrence at 3 years. CONCLUSION: HTN relapses in 1 of 5 hypertensives who have achieved remission at the first year of follow-up. Weight loss during the first postoperative year should be encouraged to avoid HTN relapse at 3 years.
