| dc.description.abstract | Objective: To evaluate the efficacy and tolerance of the levonorgestrel-releasing intrauterine system (LNG-IUS) among Portuguese women, with particular emphasis on the implications of changes in bleeding pattern. Study design Forty healthy premenopausal women (average age 42.7 ± 4.5 years) were recruited in each one of the three Portuguese centers (a total of 120) where the LNG-IUS was used as a contraceptive method during a maximum period of 5 years. All women had previously given their informed consent and were informed about the eventual changes in bleeding pattern. Serum ferritin levels and hemogram measurements were performed before and 1 year after the introduction of the IUS. The results were analyzed by the Student t test (raw data and paired test). Results: Preliminary data showed a continuation rate of 70% with an excellent efficacy rate (no pregnancies) 1 year after the introduction of the IUS. The hypomenorrhea rate was 35% while 12.5% of the women had amenorrhea. The average increase in serum ferritin level was 13 ng/ml and of hemoglobin 0.4 g/dl. The comparisons of hemoglobin results were statistically significant (p = 0.05, t raw data and p = 0.028, t paired test). Most complaints were related to cultural difficulties in accepting the changes in menstrual bleeding pattern. Conclusion In order to minimize and control the most common menstrual bleeding side-effects that occur when using this IUS, as well as to improve the continuation rate, clinicians must make a judicious choice of potential users, owing to the psychological and cultural implications that menstrual bleeding changes can have, mainly among women of low socioeconomic levels. Moreover, non-contraceptive therapeutic benefits should be emphasized. | pt_PT |
