Summary

The efficiency of the use of metformin chlorhydrate in patients with polycystic ovarian syndrome and history of infertility and menstrual disorders was evaluated in a double blinded, randomized, phase II clinical trial over a one year period at Camagüey Clinical- Surgical Teaching Hospital. The universe of study was constituted by 169 women who had previously received treatment with ovulation inductors for a period of one year or more. This universe was divided into a control group composed of 83 women treated with ovulation inductors (group I); and a group of 86 women (group II), to whom in addition to ovulation inductors, metformin chlorhydrate was administered. This last group of patients was randomly determined with the objective of avoiding associated risks. Data was processed using the SPSS statistical program for Windows. Results are expressed through frequency distribution and contigency tables. The predominant age group was 24-30 years in both groups I and II. At the onset of the study obese patients predominated in both groups. A significant progress was observed in the waist/hip index in patients that used metformin chlorhydrate, as well as a return to normalcy of the values of insulin in nearly all of these patients following the use of this product, in comparison to those of the control group. Considerable improvement was obtained in the values of the lipid profile in the control group; the state of insulin resistance improved to the point of total absence in patients treated with metformin clorhydrate. At the end of the study none of the group II patients continued with altered fasting blood sugar, although with respect to the glucose tolerance test there was no notable difference between the two groups. The use ofmetformin clorhydrate in association with the classical therapy in patients with polycystic ovarian syndrome is recommended for better results in the achievement of adequate metabolic control.

Resumen

Se realizó un ensayo clínico fase II, controlado, con asignación aleatoria, en dos ramas, donde se evaluó la eficacia del uso del clorhidrato de metformina en el tratamiento de las pacientes portadoras del síndrome de ovarios poliquísticos (SOP), con historia de infertilidad y trastornos menstruales en un período de un año en el Hospital ClínicoQuirúrgico de Camagüey. El estudio estuvo constituido por 169 mujeres que recibieron tratamiento con inductores de la ovulación (clomifeno y/o gonadotrofinas) por un período igual o mayor de un año. Las pacientes se dividieron en dos grupos, un grupo control integrado por 83 mujeres con tratamiento con inductores de la ovulación(grupo I), y otro, de 86 mujeres, al que, además, se administró clorhidrato de metformina (grupo II). Este último grupo se determinó de forma aleatoria con el objetivo de evitar riesgos. Los datos se procesaron mediante el sistema estadístico SPSS para Windows realizándose distribución de frecuencia y tablas de contingencia. El grupo de edad predominante fue elde entre 24 y 30 años en ambos grupos. En la evolución del índice de masa corporal de las pacientes, alinicio del estudio, observamos el predominio de lasobesas en ambos grupos. También observamos unprogreso significativo del índice cintura/cadera en lasque usaron clorhidrato de metformina. Después deutilizar este producto los valores de insulina se normalizaron en casi la totalidad de las pacientes a diferencia del grupo control. Se logró una mejoría considerable de los valores del perfil lipídico en el grupo control. El estado de insulinorresistencia mejoró en mayor medida en las pacientes tratadas con clorhidrato de metformina, hasta el punto de no existir. Al finalde la investigación ninguna paciente de este grupo siguió presentando alteración de la glucemia en ayunas, aunque con respecto a la prueba de tolerancia a la glucosa no existieron diferencias significativas entre ambos grupos. Es recomendable el uso del clorhidrato de metformina en asociación con la terapia clásica en las pacientes con SOP, en aras de lograr un adecuado control metabólico.
