Serial prolactin sampling as a confirmatory test for true hyperprolactinemia / Curva de prolactina para la confirmación de hiperprolactinemia real

INTRODUCTION: Hyperprolactinemia may be due to physiological or pathological causes, and may be asymptomatic or induce hypogonadism, infertility, and/or galactorrhea. It is important to take prolactin samples while avoiding stress, as this may increase prolactin levels. Therefore, our aim was to assess the value of prolactin serial sampling after brachial vein cannulation. PATIENTS AND METHODS: Sixty-six patients (34.9±11.8 years of age, 92.4% female) with an initial elevated random prolactin level were included. A prolactin sample was drawn at baseline and after a 30min rest. RESULTS: The median referral prolactin level was 37.4ng/ml (interquartile range [IQR* 23.3), the baseline prolactin level at serial sampling was 19.5ng/ml (IQR 8), and the value after a 30min rest was 17.1ng/ml (IQR 7.9). Hyperprolactinemia was not confirmed by serial sampling in 45 patients (68.2%). There were no statistically significant differences in referral prolactin levels between patients with and without confirmed hyperprolactinemia (41.2ng/ml and 36.7ng/ml respectively, p = 0.3). Galactorrhea was found in 13.6% of patients, amenorrhea or oligomenorrhea in 28.8%, infertility in 7.6%, erectile dysfunction in 4.6%, and gynecomastia in 3%, while 45.5% were asymptomatic. There were no statistical differences regarding the presence or absence of any of these symptoms and subsequent confirmed hyperprolactinemia. Fifty-seven patients (86.4%) were discharged after the results of the prolactin serial sampling were obtained. CONCLUSIONS: Prolactin serial sampling may be a useful test to detect artefactual hyperprolactinemias, thus avoiding unnecessary additional tests and treatments

INTRODUCCIÓN: La hiperprolactinemia puede ser debida a causas fisiológicas o patológicas, y puede ser asintomática o inducir hipogonadismo, infertilidad y/o galactorrea. Es importante obtener las muestras de prolactina evitando situaciones de estrés, puesto que este puede incrementar sus niveles. Por tanto, nuestro objetivo era evaluar la utilidad de la realización de curvas de prolactina mediante canalización de la vena braquial. MATERIALES Y MÉTODOS: Se incluyeron 66 pacientes (edad: 34,9±11,8 años; 92,4% mujeres) con una prolactina aleatoria inicial elevada. Se obtuvieron una muestra de prolactina basal y otra tras un reposo de 30min. RESULTADOS: La prolactina mediana inicial fue 37,4ng/ml (IQR: 23,3), la prolactina basal de la curva 19,5ng/ml (IQR: 8), y tras 30min de reposo, 17,1ng/ml (IQR: 7,9). La curva descartó una hiperprolactinemia en 45 pacientes (68,2%) No hubo diferencias estadísticamente significativas en la prolactina de derivación entre aquellos pacientes en los que se confirmó una hiperprolactinemia y aquellos que no (41,2 vs. 36,7ng/ml; p = 0,3). Un 13,6% de los pacientes presentaron galactorrea, un 28,8% amenorrea u oligomenorrea, un 7,6% infertilidad, un 4,6% disfunción eréctil y un 3% ginecomastia. El 45,5% estaban asintomáticos. No hubo diferencias estadísticamente significativas entre la presencia o ausencia de ninguno de estos síntomas y una hiperprolactinemia confirmada posteriormente. Se pudo dar de alta a 57 pacientes (86,4%) tras la obtención de los resultados de la curva de prolactina. CONCLUSIONES: La curva de prolactina puede ser una prueba útil pata detectar falsas hiperprolactinemias, evitando la realización de pruebas complementarias y tratamientos adicionales innecesarios

Are subjects with criteria for adult attention-deficit/ hyperactivity disorder doing worse after bariatric surgery? A case-control study / ¿Tienen peores resultados los individuos con criterios para trastorno por déficit de atención/ hiperactividad tras la cirugía bariátrica? Estudio de casos y controles

Introduction: There is an increasing awareness of the strong associations between obesity and adult attention-deficit/hyperactivity disorder (ADHD), with high rates of ADHD (26-61%) in patients seeking weight loss. Aims: To determine the frequency of ADHD in a bariatric surgery (BS) sample and investigate whether there were any differences among clinical, analytical and psychological parameters in individuals with criteria for ADHD. Methods: Sixty patients (78.3% female, age 46.3±9.8, months since BS 46.28±18.1) who underwent BS, with a minimum follow-up of 18 months, were evaluated cross-sectionally. Initial and current BMI, eating patterns, comorbidity, socio-demographic and biochemical parameters were recorded. For the screening of ADHD, ADHD self rating scale-v1.1 was administered. Results: Nineteen individuals (31.6%) had a positive screening for ADHD. This group had higher levels of HDL-cholesterol (62.8±17.3mg/dl vs 53.5±9.9mg/dl; p=0.011) and Apo-A (177.7±28.4mg/dl vs 154.9±34.7mg/ dl; p=0.015), and an increased consumption of lipids (42.2±7.1% vs 36.7±8.3%; p=0.019). Subjects with ADHD symptoms had more difficulties in following visits after BS (52.6% vs 24.3%; p= 0.011).We could not find any differences in achieved BMI, depressive symptoms or quality of life. Conclusions: Patients who met criteria for ADHD face significant difficulties with compliance in follow-up, but we could not find differences in major clinical outcomes. Surprisingly, these patients could have a protective lipid profile (AU)

Introducción: Hay una creciente concienciación de la fuerte asociación entre la obesidad y el trastorno por déficit de atención/hiperactividad del adulto (TDAH), con elevadas tasas de TDAH (26-61%) en los pacientes que consultan por pérdida ponderal. Objetivos: conocer la frecuencia del TDAH en una muestra de sujetos sometidos a cirugía bariátrica (CB) e investigar si existen diferencias clínicas, analíticas y psicológicas en estos sujetos. Métodos: Sesenta pacientes (78.3% mujeres, edad 46.3±9.8, meses desde la CB 46.28±18.1) sometidos a CB, con un seguimiento mínimo desde ésta de 18 meses, fueron evaluados transversalmente. Se recogieron y analizaron el IMC inicial y en el momento de la evaluación, patrones alimentarios, comorbilidades, y parámetros sociodemográficos y bioquímicos. Para el screening del TDAH se administró la versión española del 'ADHD self-rating scale v 1.1'. Resultados: Diecinueve individuos (31.6%) tenían un screening positivo para TDAH. Estos sujetos tenían niveles superiores de HDL colesterol (62.8±17.3mg/dl vs 53.5±9.9mg/dl; p=0.011) y Apo-A (177.7±28.4mg/dl vs 154.9±34.7mg/dl; p=0.015), y un consumo mayor de lípidos en la dieta (42.2±7.1% vs 36.7±8.3%; p=0.019). Estos sujetos tenían más dificultades en seguir las visitas protocolizadas tras la CB (52.6% vs 24.3%; p= 0.011). No se evidenciaron diferencias en el IMC alcanzado, síntomas depresivos o calidad de vida. Conclusiones: Los pacientes sometidos a CB con criterios para TDAH presentan más dificultades en la adherencia al seguimiento, pero no se evidenciaron diferencias en resultados clínicos relevantes. Curiosamente, estos sujetos podrían presentar un perfil lipídico protector (AU)

Cardiovascular risk profile in Mediterranean patients submitted to bariatric surgery and intensive lifestyle intervention: impact of both interventions after 1 year of follow-up.

BACKGROUND: The aim was to compare obesity-related cardiovascular (CV) risk factors (classic and emerging) and the estimated CV risk at 10 years (calculated by REGICOR) in obese Mediterranean patients submitted to bariatric surgery and intensive lifestyle intervention at baseline and after 1 year of follow-up. METHODS: Patients submitted to bariatric surgery (n = 108) and standardized program of therapeutic changes in lifestyle (n = 90) were retrospectively included. Clinical history, physical examination, and laboratory analysis were routinely determined before weight loss intervention and at 1 year follow-up. RESULTS: Seventy-five percent of the surgery patients had a CV risk lower than 5 % and not one patient had a 10-year CV risk higher than 15 %. The percentage of patients with comorbidities (diabetes and sleep apnea syndrome) was higher in the surgery group. Seventeen of the surgery patients had no comorbidities. The improvement in CV risk profile was significant higher in the surgery group. CV risk benefit of both intervention groups was related to baseline higher CV risk, with type 2 diabetes with poor metabolic control and high cholesterol levels being the most important predictors for surgery patients. Neither body mass index nor excess of weight loss was related to CV risk improvement. CONCLUSIONS: Mediterranean patients undergoing a weight loss intervention have a low CV risk. In comparison with lifestyle intervention, surgery induces a better improvement of CV risk. This benefit is related to estimated CV risk, presence of diabetes, and cholesterol levels at baseline. These observations should be taken into account in order to optimize health resources.

Treatment of depression in type 2 diabetic patients: effects on depressive symptoms, quality of life and metabolic control.

BACKGROUND AND OBJECTIVES: Type 2 diabetes (T2DM) almost doubles the risk of comorbid depression, with lifetime prevalence up to 29%. Recognition and treatment of depression in T2DM are important because of its association with hyperglycemia, diabetic complications and poor quality of life (QoL). However, although currently available medical therapy for depression is effective in reducing depressive symptoms, it does not consistently improve HbA1c levels. The aim of this study was to determine the effects of antidepressant therapy on depressive symptoms, health-related QoL and metabolic control in T2DM. METHODS: 48 T2DM (47.8% males, age 59.8 ± 11.1, T2DM duration 9.5 ± 6.5 years) who had a major depressive disorder diagnosed with a Beck Depression Inventory (BDI) test score greater than 16 and confirmed with a structured interview, were prescribed citalopram 20mg once daily. 10 out of 48 refused the prescription and were used as controls. BDI score, BMI, HbA1c and the Spanish version of the SF-36 Health Survey were recorded baseline and after 6 months of treatment. Sociodemographic characteristics, complications related to T2DM and comorbidities were also recorded. RESULTS: No differences in baseline characteristics were observed between the two groups. When compared with the untreated group (n=10), patients treated with citalopram (n=38) showed significant improvements in BDI score and in almost all areas of quality of life, except in general health and bodily pain. No differences in HbA1c, waist circumference or BMI were found. CONCLUSIONS: Treating depressive symptoms with medical therapy in T2DM is associated with improvements in QoL and depression, but with no improvement in metabolic control or weight.
