Objetivo: Demostrar el papel de los análogos agonistas de hormona liberadora de gonadotropinas en la reserva ovárica de pacientes hemato-oncológicas del Servicio de Hematología del Hospital Universitario de Caracas durante el año 2010, en tratamiento con regímenes de quimioterapia. Método: Estudio de la variable reserva ovárica, mediante la cuantificación periódica de: ritmo menstrual, concentraciones de FSH, volumen ovárico, número de folículos antrales e incidencia de embarazo. Se administró acetato de leuprolide (11,25 mg) cada 3 meses vía intramuscular; se realizaron mediciones trimestrales de las concentraciones de FSH y se practicaron ecosonogramas pélvico o transvaginal cada 6 meses. Resultados: Posterior al cumplimiento de los análogos de la hormona liberadora de gonadotropinas, se observó la aparición de amenorrea en las pacientes. Las concentraciones de FSH se mantuvieron estables, y siguieron la misma distribución (prueba de Levene p 0,2466) los volúmenes ováricos y el número de folículos antrales se mantienen estables, se rechaza la hipótesis de normalidad del grupo de diferencias al 5 % de significancia. No se registraron embarazos. Conclusión: La reserva ovárica se preserva durante el tratamiento continuo con análogos.

Objective: To demonstrate the role gonadotropin releasing hormone analogues in ovarian reserve in hematology patients in the hematology service at the Hospital Universitario de Caracas in 2010, treated with chemotherapy regimens. Method: Study of ovarian reserve variable by periodic quantification of: menstrual rhythm, concentrations of FSH, ovarian volume, antral follicle number and incidence of pregnancy. Leuprolide acetate was administered (11.25 mg) intramuscularly every 3 months, were measured quarterly and FSH concentrations were performed pelvic or transvaginal ecosonograms every 6 months. Results: After aGnRH administration, we observed the occurrence of amenorrhea in patients. FSH concentrations were stable, and followed the same distribution (Levene test p 0.2466) ovarian volume and antral follicle numbers were stable, we reject the hypothesis of normality of group differences at 5% significance. There were no pregnancies. Conclusion: Ovarian reserve is preserved during continuous treatment with analogs.

BACKGROUND: A limited number of studies have used Tissue Doppler Imaging (TDI) to evaluate the effect of statin therapy on left ventricular dysfunction in patients with chronic heart failure. In this work, we aimed to determine whether statin administration influenced prognosis, inflammatory activation and myocardial performance evaluated by Tissue Doppler Imaging in subjects enrolled in the Daunia Heart Failure Registry, a local registry of patients with chronic heart failure. METHODS: This study retrospectively analyzed 353 consecutive outpatients with chronic heart failure (mean follow-up 384 days), based on whether statin therapy was used. In all patients, several Tissue Doppler Imaging parameters were measured; circulating levels of interleukin (IL)-6, IL-10 and C-reactive protein were also assayed. RESULTS: Statin administration in 128 subjects with ischemic heart disease was associated with a lower incidence of adverse events (rehospitalization for HF 15% vs. 46%, p<0.001; ventricular arrhythmias 5% vs. 21%, p<0.01; cardiac death 1% vs. 8%, p<0.05), lower circulating levels of IL-6 (p<0.05) and IL-10 (p<0.01), lower rates of chronic heart failure (p<0.001) and better Tissue Doppler Imaging performance (E/E' ratio 12.82 + 5.42 vs. 19.85 + 9.14, p<0.001; ET: 260.62+ 44.16 vs. 227.11 +37.58 ms, p<0.05; TP: 176.79 + 49.93 vs. 136.7 + 37.78 ms, p<0.05 and St: 352.35 + 43.17 vs. 310.67 + 66.46 + 37.78 ms, p<0.05). CONCLUSIONS: Chronic ischemic heart failure outpatients undergoing statin treatment had fewer readmissions for adverse events, blunted inflammatory activation and improved left ventricular performance assessed by Tissue Doppler Imaging.
