RESUMEN
Objective: Subfertility is commonly observed in patients with rheumatoid arthritis (RA). Although the causes are not well established, the alteration of the ovarian reserve is thought to contribute to the lower chances of pregnancy. This cross-sectional study aimed to evaluate the ovarian reserve in patients with RA. Materials and methods: Two parameters associated with ovarian reserves such as the antral follicle count (AFC) and the anti-müllerian hormone (AMH) were assessed in 38 patients with RA. We also analyzed the correlation of these parameters with the medication used to treat this pathology and with the illness severity. Results: The AMH levels in women with RA were comparable to those found on healthy individuals although the RA patients were more likely to have a low AFC. Ovarian reserve and RA were neither influenced by parameters of disease activity nor by the use of medication. Conclusion: The ovarian reserve in women with RA was similar to that found in healthy individuals.
RESUMEN
OBJECTIVE: To identify the effect of apoptotic sperm elimination with MACS in patients that require IVF. METHODS: An experimental, cross-sectional, descriptive, prospective and non-blinded study of diagnostic tests performed in patients who required IVF and ICSI from July 2011 to July 2012. Ninety-two couples participated according to the treatment administered to the semen sample; in the control group: the samples were subjected only to density gradients before ICSI, in the study group: the same procedure was performed plus the addition of the MACS technique. Comparing the groups, we assessed the fertilization, division, viable embryos and clinical pregnancy rates in all cases. RESULTS: We found significant differences when using MACS technique in sperm parameters. We found no differences between the total samples of the control and study groups. When separating the own and donated eggs in each group, we found an improvement in the fertilization rates (p<0.001) of the own eggs. In both groups, the handling of donated eggs lead to a significant improvement in the immunological pregnancy test (IPT) and fetal heart rate (FHR) results. Only in the donated eggs group, where MACS was applied, could we see that all cases with positive IPT had a fetal heart rate, which shows a significant difference (p<0.002) when compared with the control group, where the percentage decreased abruptly. CONCLUSIONS: This study demonstrates the effectiveness of the use of annexins (MACS) in eliminating apoptotic sperm, and when the obtained sperm is applied to good-quality eggs.
