Repercusión de la pérdida ponderal tras cirugía bariátrica en la estructura y función cardiaca / Impact of ponderal loss after bariatric surgery on the cardiac structure and function

Introducción y objetivoEl exceso de peso puede inducir modificaciones en la estructura y función del miocardio. La presencia de hipertrofia ventricular izquierda es un predictor independiente de morbimortalidad cardiovascular.El objetivo principal del estudio ha sido conocer la prevalencia de alteraciones morfofuncionales cardiacas en pacientes con obesidad y su modificación tras la pérdida de peso después de una cirugía bariátrica (CB).Pacientes y métodosEstudio de cohortes prospectivo de 75 pacientes con obesidad y sin cardiopatía conocida a los que se les realizó un bypass gástrico. Se midieron parámetros antropométricos, analíticos y ecocardiográficos antes, a los 6 y 12 meses de la intervención.ResultadosSe incluyeron 75 pacientes (66,6% mujeres, edad media 39,3 [9,7] años e índice de masa corporal [IMC] 47,8 [7,1] kg/m2). A los 6 y 12 meses de la CB se produjo una reducción significativa del peso corporal, una mejora en los parámetros metabólicos, inflamatorios y protrombóticos, así como en los factores de riesgo cardiovascular asociados a la obesidad (hipertensión arterial [HTA], diabetes mellitus tipo 2 [DM2], dislipemia [DLP] y síndrome de apnea-hipopnea del sueño [SAHOS]).Antes de la intervención, el 62,7% de los pacientes presentaba alteración en la geometría del ventrículo izquierdo, siendo el remodelado concéntrico la más frecuente (38,7%). Además, el 50,7% presentaba disfunción diastólica. Al año de la CB, el patrón ventricular fue normal en el 92% de los casos y la función diastólica mejoró significativamente.ConclusionesNuestros resultados corroboran el efecto negativo de la obesidad sobre el miocardio, así como la potencial reversibilidad de estas alteraciones tras una pérdida significativa de peso después de una CB.

Effect of vitamin D supplementation on asthma control in patients with vitamin D deficiency: the ACVID randomised clinical trial.

BACKGROUND: The relationship between asthma and vitamin D deficiency has been known for some time. However, interventional studies conducted in this regard have shown conflicting results. OBJECTIVE: To evaluate the efficacy of vitamin D supplementation in asthmatic patients in improving the degree of control of asthma. METHODS: Randomised, triple-blind, placebo-controlled, parallel-group study in adult asthmatic patients with serum 25-hydroxyvitamin-D3 <30 ng/mL. The intervention group received oral supplementation with 16 000 IU of calcifediol per week, and the control group had placebo added to their usual asthma treatment. The study period was 6 months. The primary endpoint was the degree of asthma control as determined by the asthma control test (ACT). Secondary endpoints included quality of life measured using the mini Asthma Quality of Life Questionnaire, the number of asthma attacks, oral corticosteroid cycles, the dose of inhaled corticosteroids, number of emergency visits, unscheduled consultations with the primary care physician and hospitalisations for asthma. RESULTS: One hundred and twelve patients were randomised (mean age 55 years, with 87 (78%) being women). Of the 112 patients, 106 (95%) completed the trial. Half the patients (56) were assigned to the intervention group and the other half to the control group. A statistically significant clinical improvement was observed in the intervention group (+3.09) compared with the control group (-0.57) (difference 3.66 (95% CI 0.89 to 5.43); p<0.001) as measured using ACT scores. Among the secondary endpoints, a significant improvement in the quality of life was found in the intervention group (5.34), compared with the control group (4.64) (difference 0.7 (95% CI 0.15 to 1.25); p=0.01). CONCLUSION: Among adults with asthma and vitamin D deficiency, supplementation with weekly oral calcifediol compared with placebo improved asthma control over 6 months. Further research is needed to assess long-term efficacy and safety. TRIAL REGISTRATION NUMBER: NCT02805907.

Resistin in morbidly obese patients before and after gastric bypass surgery.

BACKGROUND AND OBJECTIVES: Resistin was originally suggested to be a potential mediator of obesity-related insulin resistance in rodents. However, in humans, the role of resistin in obesity and insulin resistance has not yet been demonstrated. The present study investigates whether there are differences in resistin levels between patients with morbid obesity and lean subjects, and analyzes changes in resistin levels after significant weight loss secondary to bariatric surgery. METHODS: Sixty-eight patients with morbid obesity (body mass index [BMI] ≥ 40 kg/m2) and 31 lean subjects (BMI < 25 kg/m2) were selected. The study variables were: weight, height, BMI, waist-hip ratio (WHR), fat mass, family history of cardiovascular disease (CVD), type 2 diabetes mellitus (DM), hypertension, dyslipidemia, smoking, glucose, glycated hemoglobin (HbA1c), insulin, high-sensitivity C-reactive protein (hsCRP), interleukin-6 (IL-6), adiponectin and resistin. Homoeostasis model assessment (HOMA) and quantitative insulin sensitivity check index (QUICKI) were calculated. The obese patients underwent gastric bypass surgery, and the above mentioned variables were reassessed after 12 months and major weight loss. RESULTS: There were no significant differences in resistin levels between morbidly obese patients and healthy subjects of normal weight, or between obese patients before and after weight loss. Resistin levels in morbidly obese patients were not correlated to adiposity anthropometric measures, insulin, glucose, HOMA, QUICKI, hsCRP, IL-6 or adiponectin. In the morbid obesity group, after one year of weight loss, the only study parameter correlated to resistin levels was IL-6. CONCLUSION: Our results do not support a relationship among resistin levels, obesity and insulin resistance in humans.

Introducción y objetivos: inicialmente se sugirió que la resistina era un mediador potencial de la resistencia a la insulina relacionada con la obesidad en roedores. Sin embargo, en seres humanos, el papel de la resistina en la obesidad y la resistencia a la insulina aún no se ha demostrado. El presente estudio investiga si existen diferencias en los niveles de resistina entre pacientes con obesidad mórbida y sujetos con normopeso, y analiza los cambios en los niveles de resistina después de la pérdida significativa de peso debida a cirugía bariátrica. Métodos: se seleccionaron 68 pacientes con obesidad mórbida (IMC ≥ 40 kg/m2) y 31 sujetos normopeso (IMC < 25 kg/m2). Las variables del estudio fueron peso, talla, IMC, relación cintura-cadera (WHR), masa grasa, antecedentes familiares de enfermedad cardiovascular, diabetes mellitus tipo 2 (DM), hipertensión arterial, dislipidemia, tabaquismo, glucosa, hemoglobina glicosilada (HbA1c), insulina, proteína C reactiva de alta sensibilidad (hsCRP), interleucina-6 (IL-6), adiponectina y resistina. Se calcularon la evaluación del modelo de homeostasis (HOMA) y el índice cuantitativo de control de sensibilidad a la insulina (QUICKI). Los pacientes obesos se sometieron a un bypass gástrico, y las variables mencionadas fueron reevaluadas después de 12 meses y una pérdida de peso importante. Resultados: no hubo diferencias significativas en los niveles de resistina entre pacientes obesos mórbidos y sujetos sanos de peso normal, ni entre pacientes obesos antes y después de la pérdida de peso. Los niveles de resistina en pacientes obesos mórbidos no se correlacionaron con medidas antropométricas de adiposidad, insulina, glucosa, HOMA, QUICKI, hsCRP, IL-6 o adiponectina. En el grupo de obesos mórbidos, al año de la pérdida de peso experimentada, el único parámetro del estudio correlacionado con los niveles de resistina fue la IL-6. Conclusión: nuestros resultados no apoyan una relación entre los niveles de resistina, la obesidad y la resistencia a la insulina en los seres humanos (AU)

Obesity, endothelial function and inflammation: the effects of weight loss after bariatric surgery.

OBJECTIVE: Obesity is associated with a high risk for atherosclerotic cardiovascular disease. There is a causal association between obesity, inflammation, insulin resistance (IR) and endothelial dysfunction. The aim of this study was to evaluate changes in IR, proinflammatory state and markers of endothelial dysfunction in morbidly obese patients after weight loss following bariatric surgery. METHODS: In this study, we measured the levels of soluble intracellular adhesion molecule-1 (sICAM1), plasminogen activator inhibitor 1 (PAI-1), high-sensitivity C-reactive protein (hs-CRP), and interleukin-6 (IL-6) in 79 morbidly obese patients at baseline and 3, 6 and 12 months after gastric bypass. Also, we evaluated changes in IR. RESULTS: Twelve months after surgery, there was a significant decrease in plasma levels of sICAM1 (p < 0.001), PAI-1 (p < 0.05), hs-CRP (p < 0.001), IL-6 (p < 0.001) and homeostasis model assessment (HOMA) (p < 0.001) and a significant increase of McAuley index (McAuley) (p < 0.001). Baseline levels of hs-PCR were positively correlated with sICAM-1 (r = 0.450, p < 0.01) and IL-6 (r = 0.451, p < 0.01). Significant correlations were also found between the decrease of PAI-1 and the decrease of hs-PCR (r = 0.425, p < 0.01) and tryglicerides (r = 0.351, p < 0.01). CONCLUSIONS: In patients with morbid obesity, substantial surgically induced weight loss is followed by a significant improvement in the endothelial function, inflammatory state and insulin sensitivity, that may reduce their cardiovascular risk. A relationship exists between improved inflammatory profile and endothelial function.

Objetivo: la obesidad está asociada con un aumento del riesgo de enfermedad cardiovascular. Se ha propuesto una relación causal entre obesidad, inflamación, resistencia a la insulina, y disfunción endotelial. El objetivo de este estudio fue valorar marcadores de insulinorresistencia, infl amación y disfunción endotelial en pacientes con obesidad mórbida antes y después de la pérdida de peso por cirugía bariátrica. Métodos: se midieron las concentraciones séricas de moléculas solubles de adhesión intercelular tipo 1 (sICAM-1), inhibidor del activador del plasminógeno tipo 1 (PAI-1), proteína C reactiva de alta sensibilidad (hs-PCR) e interleucina 6 (IL-6) en 79 pacientes con obesidad mórbida antes y a los 3, 6 y 12 meses de la realización de un by-pass gástrico. También se evaluaron índices de resistencia a la insulina. Resultados: a los 12 meses de la cirugía disminuyeron los niveles de sICAM1 (p < 0,001), PAI-1 (p < 0,05), hs-CRP (p < 0,001), IL-6 (p < 0,001) y el índice homeostasis model assessment (HOMA) (p < 0,001) y aumentó el índice McAuley (p < 0,001). Los niveles basales de hs-PCR estaban correlacionados con los de sICAM-1 (r = 0,450, p < 0,01) y de IL-6 (r = 0,451, p < 0,01). También existía correlación entre el descenso de los niveles de PAI-1 y el descenso de hs-PCR (r = 0,425, p < 0,01) y triglicéridos (r = 0,351, p < 0,01). Conclusiones: en pacientes con obesidad mórbida una importante pérdida de peso por cirugía bariátrica se acompaña de una mejora significativa de marcadores inflamatorios, de función endotelial e insulinorresistencia, lo que puede suponer una disminución del riesgo cardiovascular. Existe una relación entre mejora del perfil inflamatorio y función endotelial (AU)

Carcinoma de tiroides incidental versus no incidental: presentación clínica, tratamiento quirúrgico y pronóstico / Incidental versus non-incidental thyroid carcinoma: clinical presentation, surgical management and prognosis

Antecedentes y objetivo: El cáncer tiroideo puede manifestarse clínicamente por la presencia de un nódulo cervical, o constituir un hallazgo casual en el estudio histológico de la glándula extirpada con diagnóstico, a priori, benigno. El objetivo del presente estudio fue estudiar las diferencias clínicas, de manejo quirúrgico y curso evolutivo entre los tumores tiroideos incidentales y los tumores detectados clínicamente. Material y métodos: Estudio retrospectivo de pacientes intervenidos por enfermedad tiroidea, ya fuese benigna o maligna, en el período comprendido entre enero de 2000 y marzo de 2014. De 1.415 pacientes que se sometieron a algún tipo de cirugía tiroidea se identificaron un total de 264 neoplasias, de las cuales 170 fueron incidentales. Se realizó comparación entre carcinomas incidentales versus no incidentales. Además, entre los incidentales se compararon los casos cuya indicación quirúrgica fue enfermedad de Graves frente a bocio multinodular. Resultados: Los carcinomas incidentales presentaron estadios más precoces y requirieron cirugía menos agresiva. No se observaron diferencias en las complicaciones quirúrgicas entre ambos grupos, aunque tanto la mortalidad como las tasas de recidiva fueron notablemente mayores en el grupo de no incidentales (4,4% vs 0% y 13,2% vs 4,8% respectivamente). Los carcinomas desarrollados sobre enfermedad de Graves no mostraron diferencias respecto al resto de los tumores incidentales, respecto a complicaciones, mortalidad o recidiva tras la cirugía. Conclusiones: El cáncer tiroideo en estadios iniciales presenta mayor supervivencia y mejor respuesta al tratamiento quirúrgico (AU)

Background and objective: Thyroid cancer may be clinically evident as a tumor mass in the neck or as a histopathological incidental finding after thyroid surgery for an apparent benign condition. Our objective was to assess the differences in clinical signs, surgical management, and course between incidental and clinically diagnosed thyroid tumors. Methods: A retrospective study was conducted on patients operated on for benign or malignant thyroid disease from January 2000 to March 2014. Among the 1415 patients who underwent any thyroid surgery, 264 neoplasms were found, of which 170 were incidental. A comparison was made of incidental versus non-incidental carcinomas. Among incidental carcinomas, cases whose indication for surgery was Graves’ disease were compared to those with multinodular goiter. Results: Incidental carcinomas were in earlier stages and required less aggressive surgery. There were no differences in surgical complications between incidental and clinical tumors, but mortality and relapses were markedly higher in non-incidental cancers (4.4% vs 0% and 13.2% vs 4.8% respectively). Carcinomas developing on Graves’ disease showed no differences from all other incidental tumors in terms of complications, mortality, or relapse after surgery. Conclusions: Early stage thyroid cancer has better survival and prognosis after surgical treatment (AU)

Obesity and inflammation: change in adiponectin, C-reactive protein, tumour necrosis factor-alpha and interleukin-6 after bariatric surgery.

BACKGROUND: Obesity is associated with a low-grade inflammatory state. A causal association between inflammation and atherosclerosis has been suggested. The aim of this study was to evaluate changes in the proinflammatory profile of morbidly obese patients after weight loss following bariatric surgery. METHODS: In this study, we measured levels of adiponectin, high-sensitivity C-reactive protein (hs-CRP), tumour necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) and their relation to insulin resistance and lipid parameters in 60 morbidly obese women at baseline and 3, 6 and 12 months after gastric bypass. RESULTS: Twelve months after surgery, there was a significant increase in plasma levels of adiponectin (p < 0.001) and high-density lipoprotein cholesterol (p < 0.01) and a significant decrease in levels of IL-6 (p < 0.001), hs-CRP (p < 0.001), cholesterol (p < 0.001), triglycerides (p < 0.001), low-density lipoprotein cholesterol (p < 0.001), glucose (p < 0.001), insulin (p < 0.001) and homeostasis model assessment (HOMA; p < 0.001). At 12 months, correlations were seen between IL-6 levels and the following: body mass index (BMI) (r = 0.53, p < 0.001), insulin (r = 0.51, p < 0.001) and HOMA (r = 0.55, p < 0.001). Also, hs-CRP levels correlated with BMI (r = 0.40, p = 0. 004), triglycerides (r = 0.34, p = 0.017), insulin (r = 0.50, p = 0.001) and HOMA (r = 0.46, p = 0.002). CONCLUSIONS: In patients with morbid obesity, significant weight loss is followed by a significant improvement in the inflammatory state, insulin sensitivity and lipid profile. A relationship exists between improved inflammatory profile and insulin sensitivity.

[Soluble intercellular adhesion molecule-1 and C reactive protein after bariatric surgery]. / Moléculas solubles de adhesión intercelular tipo 1 y proteína C reactiva tras cirugía bariátrica.

BACKGROUND AND OBJECTIVES: Obesity is associated with a state of chronic low-grade inflammation. A causal association between inflammatory processes and atherogenesis has been proposed. The aim of this study was to evaluate changes in the proinflammatory profile of morbidly obese patients who underwent bariatric surgery. Serum C-reactive protein (CRP) and soluble intercellular adhesion molecule-1 (sICAM-1) concentrations were measured before and after massive weight loss due to gastric bypass. METHODS: In this prospective study we measured CRP and sICAM-1 concentrations in 50 morbidly obese patients (19 men and 31 women) at baseline and 3, 6 and 12 months after gastric bypass. RESULTS: Body mass index (BMI), CRP, and sICAM-1 decreased significantly. BMI correlated with CRP but not with sICAM-1. CONCLUSIONS: The improvement in vascular risk profile after weight loss in morbidly obese patients could be partially explained by changes in inflammatory status.

Se encontró correlación entre IMC y PCR, pero no entre IMC y sICAM-1.ConclusiónLa mejora del perfil de riesgo vascular en pacientes obesos tras la pérdida de peso podría atribuirse, en parte, a la mejora del estado inflamatorio (AU)

Tratamiento a largo plazo de un adenoma secretor de tirotropina con análogos de somatostatina / Long term treatment of a thyrotropin secreting adenoma with somatostatin analogues

Los tumores hipofisarios secretores de tirotropina (tirotropinomas) son menos del 1% de los adenomas hipofisarios y una causa rara de hipertiroidismo. La mayoría se diagnostica como macroadenoma, y los microadenomas son excepcionales. Debe hacerse el diagnóstico diferencial con la resistencia a las hormonas tiroideas. El tratamiento de elección es la adenomectomía transesfenoidal. Si fracasa, los análogos de somatostatina son una alternativa terapéutica. Presentamos a una paciente con un microadenoma productor de tirotropina en quien se practicó una adenomectomía transesfenoidal. Tras el fracaso de la cirugía, se inició tratamiento con un análogo de somatostatina. En laactualidad, después de 9 años, la paciente continúa el tratamiento y el hipertiroidismo y el crecimiento tumoral están controlados (AU)

Thyrotropin secreting adenomas (TSHomas)account for less than 1% of all pituitary adenomas and are a rare cause of hyperthyroidism. Most cases correspond to macroadenomas, microadenomas beingexceptional. Differential diagnosis should be made with resistance to thyroid hormones. The first line treatment is transphenoidal surgery. When surgery is unsuccessful, somatostatin analogues are a therapeutic alternative. We report a patient with a TSH-secreting microadenoma. The microadenoma was resected through the transsphenoidal route. Because surgery was unsuccessful, medical therapy with somatostatin analogue was initiated. Currently, 9 years later, the patient continues to be under treatment with somatostatin analogue therapy, which has controlled the hyperthyroidism and tumoral growth. We describe successful long-term treatment of a TSH-oma with somatostatin analogue therapy when surgery is unsuccessful (AU)

[Atorvastatin lowers C-reactive protein in dislipemic patients with type 2 diabetes mellitus]. / Descenso de proteína C reactiva tras tratamiento con atorvastatina en diabéticos tipo 2 con dislipemia.

BACKGROUND AND OBJECTIVE: Type 2 diabetes mellitus is associated with an augmented risk for cardiovascular disease. The levels of C-reactive protein (CRP), the prototypic marker of inflammation, are associated with an increased risk for cardiovascular events. The statins have direct anti-inflammatory effects. Thus, we tested the effects of atorvastatin on levels of CRP on patients with type 2 diabetes. PATIENTS AND METHOD: We evaluated CRP in baseline and 6 months after onset of 20 mg daily atorvastatin therapy of 30 patients with type 2 diabetes with hyperlipidemia. Clinical and biochemical data were obtained. RESULTS: CRP-levels were significantly decreased after treatment with atorvastatin compared with baseline (median change: -4,99 mg/l; p < 0.001). We observed an correlation between CRP baseline with body mass index (r = 0.429; p = 0.018), serum fibrinogen (r = 0.607; p = 0.001) and microalbuminuria (r = 0.470; p = 0.01). Conversely, there was no significant correlation between CRP baseline with LDL cholesterol. The CRP reduction was significantly correlated with fasting glucose (r = -0.457; p = 0.019) and glycosylated hemoglobin at 6 months (r = -0.421; p = 0.03). CONCLUSIONS: These results confirm findings from previous studies that atorvastatin reduce CRP levels in a largely LDL cholesterol independent manner.
