ABSTRACT
Se busca cualificar y cuantificar los cambios clínicos no detectables en los estadíos iniciales de la enfermedad tiroidea, a través de la ecografía orbitaria y la ecografía Doppler-dúplex color; adicionalmente medir los valores hemodinámicos de la arteria y vena oftálmicas, con el fin de detectar modificaciones precoces observables en el nervio óptico. Estudio descriptivo, transversal, y correlacionalde 80 pacientes; 40 pacientes con diagnóstico de enfermedad tiroidea y 40 pacientes grupo control, a los que se les realizó ecografía orbitaria y Doppler color desde Julio a Diciembre. Del grupo con enfermedad tiroidea, 90% eran femeninos y 10% masculinos; 75% tenían entre 25-59 años, 45% hipertiroideos, 35% hipotiroideos y 10% eutiroideos; 35% presentaron hábitos tabáquicos positivos y 47,5% hábitos cafeínicos. El 87,3% tenían exoftalmometrías<23mm. Hubo reflectividad moderada en 136 músculos (43%) predominando en el complejo recto superior-elevador del párpado superior. El índice de pulsatibilidad, índice de resistencia y la velocidad pico sistólico de la arteria oftálmica se encontró elevados en los hipertiroideos. Los índices de la vena oftálmica como V1 y V2 estuvieron elevados en los tres grupos (hiper, hipo y eutiroideos). Concluyendo que el eco orbitario evalúa alteraciones cuantitativas y cualitativas tales como grosor muscular, alteraciones en la reflectividad interna de los mismos, edema asociados a las glándulas lagrimales, edema en la cabeza de los nervios ópticos, cambios en la grasa orbitaria, etc., los cuales son significativos en el diagnóstico y seguimiento de estos pacientes. El eco Doppler reveló alteraciones hemodinámicas importantes en parámetros índices de pulsatibilidad y velocidad pico sistólico en los pacientes hipertiroideos.
This paper seeks to qualify and quantify non detectable clinical changes in the initial stages of thyroid disease, through orbit ultrasound and Doppler color duplex ultrasonography; as well as to measure the hemodynamic values of the ophthalmic artery and vein for early detection of observable changes in the optic nerve. Descriptive, cross-sectional and correlational field study of 80 patients, 40 patients diagnosed with thyroid disease and 40 control group patients, who underwent orbital color Doppler ultrasound from July 2006 to December 2007. From the thyroid disease group, 90% were female and 10% male; 75% were between 25-59 years, 45% with hyperthyroidism, 35% with hypothyroidism and 10% euthyroid; 35% had positive smoking habits and 47.5% caffeine habits. 87.3% with <23mm of Exophtalmometry. Moderate reflectivity was present in 136 muscles (43%) with predominance in the upper-right lifting complex of the upper eyelid. Pulsatility index, resistance index and systolic peak velocity of the ophthalmic artery were elevated in hyperthyroidism subjects. Indices of the ophthalmic vein as V1 and V2 were elevated in all groups (hyper, hypo and euthyroid). It is concluded that the orbital eco evaluates quantitative and qualitative alterations such as edema and fibrosis, which are significant in the diagnosis and monitoring of these patients. The Doppler echo revealed significant hemodynamic changes in pulsatility index parameters and systolic peak velocity in hyperthyroidism patients.
ABSTRACT
Objective The aim of the study was to assess the prevalence and characteristics of metabolic syndrome (MetS) and its elements in relation to TSH in euthyroid subjects. Materials and methods In the cross-sectional study, 2,153 euthyroid adults, 47.2 ± 14.5 years (20-94) with no current antithyroid or thyroid replacement therapy were enrolled. All participants filled a questionnaire on past and current morbidities, medication and smoking. Body weight, height, waist circumference, serum TSH, glucose and lipids were measured. The subjects were stratified by quartiles of TSH (QTSH) and the prevalence of the MetS elements was calculated. MetS was determined by the IDF 2005 criteria. Results Overweight prevalence was 37.2% (35.2-39.2), obesity in 25.1% (23.3-26.9), abdominal obesity – 61.4% (59.3-63.5), hypertension – 42.1% (38.9-43.1), diabetes/increased fasting glucose – 13.6% (12.1-15), low HDL-cholesterol – 27.6% (25.7-29.5), hypertriglyceridemia – 24.1% (22.3-25.9), MetS – 32.2% (30.2-34.2). MetS was more prevalent in the highest QTSH (34.9%, 30.9-38.9) than the lowest (27%, 23.3-30.9), p < 0.001, as were low HDL-C (32%, 28-35.9 vs. 25%, 21.3-28.7, p < 0.001) and hypertriglyceridemia (26.8%, 23-30.5 vs. 20.4%, 17-23.8, p = 0.015). Each QTSH increased the risk of MetS by 14%, p < 0.001, of hypertriglyceridemia by 20%, p = 0.001 and of low LDL-C by 9%, p = 0.042. Other significant factors for MetS were age, male gender and obesity. Conclusion The prevalence of MetS increased with higher QTSH within the euthyroid range, mostly by an increase in the dyslipidemia. Arq ...
Objetivo O objetivo deste estudo foi avaliar a prevalência e características da síndrome metabólica (MetS) e seus elementos em relação ao TSH em sujeitos eutireoides. Materiais e métodos Foram analisados, em um estudo transversal, 2.153 adultos eutiroides, de 47,2 ± 14,5 anos (20-94) sem terapia antitiroidiana ou de reposição. Todos os participantes preencheram um questionário sobre doenças atuais e passadas, medicações e tabagismo. O peso corporal, altura, circunferência da cintura, TSH, glicose e lipídios séricos foram medidos. Os sujeitos foram estratificados em quartis de TSH (QTSH) e a prevalência dos elementos da MetS foram calculados. Os critérios da MetS foram determinados pela IDF 2005. Resultados A prevalência de sobrepeso foi de 37,2% (35,2-39,2), de obesidade – 25,1% (23,3-26,9), obesidade abdominal – 61,4% (59,3-63,5), hipertensão – 42,1% (38,9-43,1), diabetes/aumento da glicose de jejum – 13,6% (12,1-15), baixo colesterol HDL – 27,6% (25,7-29,5), hipertrigliceridemia – 24,1% (22,3-25,9), MetS – 32,2% (30,2-34,2). A MetS foi mais prevalente no QTSH mais alto (34,9%; 30,9-38,9) do que no mais baixo (27%; 23,3-30,9), p < 0,001, assim como o baixo HDL-C (32%, 28-35,9 contra 25%, 21,3-28,7; p < 0,001) e hipertrigliceridemia (26,8%; 23-30,5 contra 20,4%, 17-23,8; p = 0,015). Cada QTSH aumentou o risco MetS em 14%, p < 0,001, de hipertrigliceridemia em 20%, p = 0,001 e de baixo LDL-C em 9%, p = 0,042. Outros fatores significativos para a MetS foram idade, sexo masculino e obesidade. ...
