Evaluación de las alteraciones lipídicas en el síndrome de ovarios poliquísticos y su relación con la resistencia a la insulina / Assessment of the lipid alterations in polycystic ovaries syndrome and its relation to insulin-resistance

El síndrome de ovarios poliquísticos excede el eje reproductivo por su frecuente asociación con alteraciones metabólicas y cardiovasculares. Objetivo: basado en lo anterior se realizó un estudio descriptivo transversal para determinar la frecuencia y las características de las alteraciones lipídicas en un grupo de mujeres con síndrome de ovarios poliquísticos y su relación con las alteraciones en la sensibilidad a la insulina. Se estudiaron 23 mujeres según los criterios de la Androgen Excess Society, se realizaron determinaciones hormonales y lipídicas así como glucemia e insulinemia en ayunas para evaluar sensibilidad a la insulina. Resultados: 95,6 por ciento de las pacientes presentaron dislipidemia. La disminución de las lipoproteínas de alta densidad (cHDL) y apolipoproteínas (Apo) A-I fueron las alteraciones lipídicas más frecuentes (91,3 y 87,0 por ciento, respectivamente) mientras que el aumento de los triglicéridos (Tg) y del colesterol total (Ct) fueron infrecuentes (13 y 4,3 por ciento, respectivamente). Los índices lipídicos calculados: Tg/cHDL, Ct/cHDL, cHDL/cLDL y Apo B/A-I tuvieron valores medios superiores en las mujeres con insulinorresistencia, el índice Apo B/A-I fue el que mostró mayor diferencia en mujeres con insulinorresistencia y sin esta. La frecuencia de las alteraciones lipídicas en las mujeres estudiadas fue alta pero no todas se relacionan con la insulinorresistencia, lo cual sugiere que en la expresión del síndrome de ovarios poliquísticos podrían intervenir múltiples factores metabólicos y hormonales(AU)

The polycystic ovaries syndrome to exceed the reproductive axis due to its frequent association with metabolic and cardiovascular alterations. Objetive: based on above mentioned a cross-sectional and descriptive study was conducted to determine the frequency and the characteristic of lipid alterations en a group of women diagnosed with polycystic ovaries and its relation to alterations in insulin-sensitivity. Methods: twenty three women were studied according to Androgen Excess Society criteria, hormonal and lipid determinations were made as well as fasting glycemia and insulinemia to assess the insulin-sensitivity. RESULTS: the 95,6 percent of patients presenting with dyslipemia. The more frequent lipid alterations were a decrease of the high density lipoproteins (cHDL) and apolipoproteins (Apo) (91,3 and 87,0 percent, respectively) whereas the increase of triglycerides(Tg) and the total cholesterol (tC) were infrequent (13 and 4,3 percent, respectively). The estimated lipid rates: Tg/cHDL, Ct/cHDL, cHDL/cLDL and Apo B/A-I had higher mean values in women with insulin-resistance; the Apo B/A-I rate had the greater difference in women with insulin-resistance and without it. The lipid alterations frequency in study women suggest that in expression of polycystic ovaries syndrome could be involved many metabolic and hormonal factors(AU)

Modificações do estilo de vida na síndrome dos ovários policísticos: papel do exercício físico e importância da abordagem multidisciplinar / Lifestyle modifications in the polycystic ovary syndrome: role of physical exercise and importance of multidisciplinary approach

A síndrome dos ovários policísticos (SOP) é uma desordem endócrina heterogênea com prevalência de 5 a 10 por cento nas mulheres em idade reprodutiva. Na SOP, há associação com vários fatores de risco para desenvolvimento de doença cardiovascular, como resistência à insulina, dislipidemia, diabetes mellitus, hipertensão arterial, disfunção endotelial, obesidade central, síndrome metabólica e marcadores pró-inflamatórios crônicos. A prática de exercício físico, juntamente com orientação nutricional, tem sido recomendada como estratégia de primeira linha no tratamento da oligomenorréia, hirsutismo, infertilidade e obesidade nas mulheres com SOP. Nesse sentido, o objetivo da presente revisão foi analisar o papel específico do exercício e/ou atividade física nas modificações da composição corporal, sistema cardiovascular, níveis plasmáticos bioquímicos e hormonais e função reprodutiva de mulheres com SOP.

The polycystic ovaries syndrome (POS) is a heterogeneous endocrinal disorder prevalent in 5 to 10 percent of women in reproductive age. In POS, there is an association with risk factors linked to the development of cardiovascular disease such as insulin resistance, dislipidemia, diabetes mellitus, arterial hypertension, endothelial dysfunction, central obesity, metabolic syndrome and chronic pro-inflammatory markers. Physical exercise practice together with nutritional guidance have been recommended as first rate strategies in the treatment of oligomenorrhea, hirsutism, infertility and obesity in POS women. This way, the objective of the present review was to analyze the specific role played by exercise and/or physical activity in changes of the body shape, in biochemical and hormonal plasmatic levels, and in the POS women’s reproductive function.
