RESUMO

STUDY QUESTION: Is a single endometrial scratch prior to the second fresh IVF/ICSI treatment cost-effective compared to no scratch, when evaluated over a 12-month follow-up period? SUMMARY ANSWER: The incremental cost-effectiveness ratio (ICER) for an endometrial scratch was €6524 per additional live birth, but due to uncertainty regarding the increase in live birth rate this has to be interpreted with caution. WHAT IS KNOWN ALREADY: Endometrial scratching is thought to improve the chances of success in couples with previously failed embryo implantation in IVF/ICSI treatment. It has been widely implemented in daily practice, despite the lack of conclusive evidence of its effectiveness and without investigating whether scratching allows for a cost-effective method to reduce the number of IVF/ICSI cycles needed to achieve a live birth. STUDY DESIGN, SIZE, DURATION: This economic evaluation is based on a multicentre randomized controlled trial carried out in the Netherlands (SCRaTCH trial) that compared a single scratch prior to the second IVF/ICSI treatment with no scratch in couples with a failed full first IVF/ICSI cycle. Follow-up was 12 months after randomization.Economic evaluation was performed from a healthcare and societal perspective by taking both direct medical costs and lost productivity costs into account. It was performed for the primary outcome of biochemical pregnancy leading to live birth after 12 months of follow-up as well as the secondary outcome of live birth after the second fresh IVF/ICSI treatment (i.e. the first after randomization). To allow for worldwide interpretation of the data, cost level scenario analysis and sensitivity analysis was performed. PARTICIPANTS/MATERIALS, SETTING, METHODS: From January 2016 until July 2018, 933 women with a failed first IVF/ICSI cycle were included in the trial. Data on treatment and pregnancy were recorded up until 12 months after randomization, and the resulting live birth outcomes (even if after 12 months) were also recorded.Total costs were calculated for the second fresh IVF/ICSI treatment and for the full 12 month period for each participant. We included costs of all treatments, medication, complications and lost productivity costs. Cost-effectiveness analysis was carried out by calculating ICERs for scratch compared to control. Bootstrap resampling was used to estimate the uncertainty around cost and effect differences and ICERs. In the sensitivity and scenario analyses, various unit costs for a single scratch were introduced, amongst them, unit costs as they apply for the United Kingdom (UK). MAIN RESULTS AND THE ROLE OF CHANCE: More live births occurred in the scratch group, but this also came with increased costs over a 12-month period. The estimated chance of a live birth after 12 months of follow-up was 44.1% in the scratch group compared to 39.3% in the control group (risk difference 4.8%, 95% CI -1.6% to +11.2%). The mean costs were on average €283 (95% CI: -€299 to €810) higher in the scratch group so that the point average ICER was €5846 per additional live birth. The ICER estimate was surrounded with a high level of uncertainty, as indicated by the fact that the cost-effectiveness acceptability curve (CEAC) showed that there is an 80% chance that endometrial scratching is cost-effective if society is willing to pay ∼€17 500 for each additional live birth. LIMITATIONS, REASONS FOR CAUTION: There was a high uncertainty surrounding the effects, mainly in the clinical effect, i.e. the difference in the chance of live birth, which meant that a single straightforward conclusion could not be ascertained as for now. WIDER IMPLICATIONS OF THE FINDINGS: This is the first formal cost-effectiveness analysis of endometrial scratching in women undergoing IVF/ICSI treatment. The results presented in this manuscript cannot provide a clear-cut expenditure for one additional birth, but they do allow for estimating costs per additional live birth in different scenarios once the clinical effectiveness of scratching is known. As the SCRaTCH trial was the only trial with a follow-up of 12 months, it allows for the most complete estimation of costs to date.

RESUMO

STUDY QUESTION: Does endometrial scratching in women with one failed IVF/ICSI treatment affect the chance of a live birth of the subsequent fresh IVF/ICSI cycle? SUMMARY ANSWER: In this study, 4.6% more live births were observed in the scratch group, with a likely certainty range between -0.7% and +9.9%. WHAT IS KNOWN ALREADY: Since the first suggestion that endometrial scratching might improve embryo implantation during IVF/ICSI, many clinical trials have been conducted. However, due to limitations in sample size and study quality, it remains unclear whether endometrial scratching improves IVF/ICSI outcomes. STUDY DESIGN, SIZE, DURATION: The SCRaTCH trial was a non-blinded randomised controlled trial in women with one unsuccessful IVF/ICSI cycle and assessed whether a single endometrial scratch using an endometrial biopsy catheter would lead to a higher live birth rate after the subsequent IVF/ICSI treatment compared to no scratch. The study took place in 8 academic and 24 general hospitals. Participants were randomised between January 2016 and July 2018 by a web-based randomisation programme. Secondary outcomes included cumulative 12-month ongoing pregnancy leading to live birth rate. PARTICIPANTS/MATERIALS, SETTING, METHODS: Women with one previous failed IVF/ICSI treatment and planning a second fresh IVF/ICSI treatment were eligible. In total, 933 participants out of 1065 eligibles were included (participation rate 88%). MAIN RESULTS AND THE ROLE OF CHANCE: After the fresh transfer, 4.6% more live births were observed in the scratch compared to control group (110/465 versus 88/461, respectively, risk ratio (RR) 1.24 [95% CI 0.96-1.59]). These data are consistent with a true difference of between -0.7% and +9.9% (95% CI), indicating that while the largest proportion of the 95% CI is positive, scratching could have no or even a small negative effect. Biochemical pregnancy loss and miscarriage rate did not differ between the two groups: in the scratch group 27/153 biochemical pregnancy losses and 14/126 miscarriages occurred, while this was 19/130 and 17/111 for the control group (RR 1.21 (95% CI 0.71-2.07) and RR 0.73 (95% CI 0.38-1.40), respectively). After 12 months of follow-up, 5.1% more live births were observed in the scratch group (202/467 versus 178/466), of which the true difference most likely lies between -1.2% and +11.4% (95% CI). LIMITATIONS, REASONS FOR CAUTION: This study was not blinded. Knowledge of allocation may have been an incentive for participants allocated to the scratch group to continue treatment in situations where they may otherwise have cancelled or stopped. In addition, this study was powered to detect a difference in live birth rate of 9%. WIDER IMPLICATIONS OF THE FINDINGS: The results of this study are an incentive for further assessment of the efficacy and clinical implications of endometrial scratching. If a true effect exists, it may be smaller than previously anticipated or may be limited to specific groups of women undergoing IVF/ICSI. Studying this will require larger sample sizes, which will be provided by the ongoing international individual participant data-analysis (PROSPERO CRD42017079120). At present, endometrial scratching should not be performed outside of clinical trials.

RESUMO

OBJECTIVES: To compare the value of transvaginal ultrasonographic measurement of the cervical length versus the Bishop score, prior to induction of labour, in predicting the mode of delivery within four days. MATERIALS AND METHODS: This longitudinal study included 110 women (at term, singleton, vertex presentation) in whom induction of labour was performed at 37-42 weeks of gestation. Cervical length on transvaginal ultrasound and the Bishop score were assessed prior to induction according to standard protocol. Medical records were reviewed for relevant-- demographic and clinical data. Primary outcome criterion was successful vaginal delivery within 96 h. Univariate analyses and receiver operating characteristic (ROC) curves were used to examine differences between variables possibly predicting outcome. RESULTS: Of the 110 women 66 were nulliparous and 44 multiparous. Vaginal delivery within 96 h was successful in 48 (73%) nulliparous and in 40 (91%) multiparous women ( i.e. in 80% of the total population). The overall rate of caesarean delivery was 17%. THERE WAS A SIGNIFICANT DIFFERENCE BETWEEN NULLIPAROUS AND MULTIPAROUS WOMEN IN AGE, CERVICAL LENGTH (MEAN IN MM IN NULLIPAROUS WOMEN: 29.31, range: 5.00-56.00; in multiparous women: 37.04, range: 12.00-56.00), Bishop score and successful induction, but no significant difference between these subgroups in neonatal outcomes. Only the Bishop score in nulliparous women showed a significant relationship between this variable and predicting successful labour induction (area under the ROC curve 0.679; standard error 0.73; p < 0.05; 95% CI: 0.536-0.823). The best cut-off value for the Bishop score was 3, with a sensitivity of 56.3% and a specificity of 72.2%. CONCLUSION: In this study group significant independent prediction of vaginal delivery within 96 h is provided by the Bishop score but only in nulliparous women. Transvaginal ultrasonographic measurement of cervical length is not a significant independent predictor of vaginal delivery within 96 h.

RESUMO

Steroid drugs with contraceptive properties have been available in the clinical setting for over four decades and are still subject to improvement. Estrogens, progestins and anti-progestins have been used alone or in various combinations, regimens and routes of administration to favour the balance between efficacy and undesirable effects. One of the most important changes in this respect is the gradual lowering of steroid dosage in commercially available contraceptives. Current steroid contraceptive pills still achieve the goal of suppression of pituitary-ovarian activity, but the margins for error are minimal. In this review the available data on modes of action and the effects on suppressing pituitary-ovarian activity by different forms of oral contraception are reassessed. Although pregnancy rates provide a crude measure of contraceptive efficacy, no benchmark for pituitary-ovarian inhibition is available to test the suppressive potential of contraceptive drugs. Consequently, many studies provide incomplete and/or incomparable results. For the further study of those forms of steroid contraception that rely predominantly on suppression of ovarian activity, prevention of dominant follicles selection should be the objective.

RESUMO

BACKGROUND: The safety and efficacy of the anti-progestogen Org 31710 in improving cycle control in healthy women using the desogestrel progestogen-only pill was investigated in this randomized, double-blind, placebo-controlled study. METHODS: A total of 103 women using the 75 micro g desogestrel progestogen-only pill daily also received either 150 mg Org 31710 or placebo once every 28 days, starting on day 1, for a duration of 4-7 treatment cycles. RESULTS: The percentage of women with bleeding or spotting (B/S) every day in the placebo group was on average 30% during the whole treatment period and no days without reported B/S occurred. In contrast, a cyclic pattern was observed for the Org 31710 group; a peak incidence of B/S was observed on day 3 or 4 of each cycle, followed by a sharp decrease on cycle days 9-15. Compared with controls, less subjects in the Org 31710 group reported irregular, frequent or prolonged bleeding. These differences were clearly observed in the initial cycles, but were somewhat less pronounced during the later cycles of the treatment period. A relatively high incidence of B/S episodes starting in the second section of the cycle was also observed. CONCLUSION: The addition of Org 31710 once a month improved cycle control in women using daily treatment with 75 micro g desogestrel.

RESUMO

OBJECTIVE: Compare spontaneous recovery of pituitary-ovarian activity during the pill-free period following the correct use of low-dose oral contraceptives and subsequent ovarian function during the administration of exogenous recombinant FSH (recFSH) after switching to continued Lyndiol (2.5 mg lynestrenol + 0.05 mg ethinyl-oestradiol) medication. DESIGN: Prospective, randomized, group-comparative, single-centre study. Following the monitoring of the pill-free period (week 1) and subsequent treatment with Lyndiol (for a total of 5 weeks), all subjects were randomly allocated to one of four groups receiving daily FSH injections for 1 week [75, 150, 225 IU recFSH or 150 IU purified urinary FSH (uFSH)] during the fourth week of Lyndiol use. PATIENTS: Thirty-six healthy volunteers aged 18-39 years, prestudy oral contraceptive use for at least 3 months, cycle length between 24 and 35 days. MEASUREMENTS: Serum FSH, LH and oestradiol (E2) concentrations as well as transvaginal ultrasound assessment of the number and diameter of follicles > 2 mm were used to monitor pituitary ovarian function. RESULTS: At the start of the pill-free period following the prestudy contraceptive medication, 67% of the women presented with LH and FSH levels < 1 IU/l and only one follicle > 10 mm was observed. Initial levels of LH and FSH correlated (P < 0.05) with the extent of pituitary-ovarian activity during the pill-free period. At the end of the pill-free period a follicle > 10 mm had emerged in one subject only. During the first 3 days of Lyndiol use, seven women (19%) eventually showed at least one follicle > 10 mm. During combined exogenous FSH and Lyndiol administration, LH levels remained completely suppressed (< or = 0.5 IU/l) in all women studied. FSH levels and number and size of follicles increased with increasing doses of exogenous FSH in a dose-dependent manner. E2 levels remained low in all groups (< 150 pmol/l). During the week following FSH administration, FSH levels and E2 levels decreased gradually while the number of follicles > 10 mm still increased. CONCLUSIONS: We have confirmed that dominant follicles > 10 mm are present at the end of the pill-free period and during the first days after resumption of pill intake. Once follicles > 10 mm arose at the end of the pill-free period, continued use of Lyndiol did not reduce follicle diameters. One week of Lyndiol reduces pituitary-ovarian activity to levels observed after 3 weeks of low-dose pills. FSH administration during Lyndiol resulted in dose-dependent follicle growth despite extremely low LH levels. E2 secretion (56 +/- 51 pmol/l) occurred to a limited and variable extent along with extremely low serum LH concentrations. Recovery of pituitary-ovarian activity at the end of the pill-free period is comparable to FSH levels and follicle dynamics following 7 days of 75-150 IU/l recFSH.

RESUMO

Endocrine and ultrasound effects were studied of an intermittent (every 28 days) oral administration of 150 mg of the anti-progestagen Org 31710 during the continued daily use of 75 microg desogestrel (DSG) for progestagen-only contraception. A randomized, double-blind, placebo-controlled two-centre study was conducted in 50 healthy volunteers. Serum luteinizing hormone (LH), follicle stimulating hormone (FSH), oestradiol and progesterone concentrations, and follicle number and size were studied, as well as endometrial thickness, which was assessed by transvaginal sonography at least twice weekly during a single medication cycle (cycle 3-5). Forty-eight women were evaluated (Org 31710, n = 25; placebo, n = 23). Seven ovulations were observed in the treated group versus none in the placebo group. LH concentrations were higher on days 9 and 11 and oestradiol concentrations lower on day 3 in the treated group, irrespective of whether ovulation occurred. No parameter could predict ovulation. Endometrial thickness was greater on cycle days 7-13 and 19 in the treated group. However, within the Org 31710 group, no significant differences were found in volunteers who did or did not ovulate. Observed differences may be attributed to a competitive effect of Org 31710 with progestagen-induced suppression of the pituitary-ovarian axis, altered oestradiol feedback mechanisms, and/or altered receptor availability.

RESUMO

This study was performed to evaluate pituitary-ovarian recovery in the pill-free interval during use of three low-dose combined oral contraceptives (COC). Either the estrogen component or the progestin component was comparable in the study groups, to evaluate their relative influence. Serum luteinizing hormone (LH), follicle-stimulating hormone (FSH), and estradiol (E2) levels were measured and follicle number and size estimated by transvaginal sonography daily during the 7-day pill-free interval in 44 healthy volunteers using three different low-dose oral contraceptives. Healthy volunteers were enrolled using 20 micrograms ethinyl estradiol (EE) + 75 micrograms gestodene (GSD) (Harmonet, Wyeth-Lederle; n = 15), 20 micrograms EE + 150 micrograms desogestrel (DSG) (Mercilon, Organon n = 17), or 30 micrograms EE + 150 micrograms DSG (Marvelon, Organon, n = 12) given according to the usual regimen of one tablet daily during 3 weeks and 1 week pill-free interval. No ovulations were observed. Pituitary hormones were not statistically significantly different at the beginning of the pill-free interval between the study groups. FSH concentrations were significantly higher at the end of the pill-free interval in the 30 micrograms EE group compared with both 20 micrograms EE groups (7.0 [0.6-12.4] IU/L vs 4.9 [1.4-6.1] IU/L and 4.5 [2.4-7.4] IU/L; p = 0.001). In both 20 micrograms EE groups, a single persistent follicle (24 and 28 mm) was present in one subject. Follicle diameters were statistically significantly smaller at the beginning and at the end of the pill-free period in the 30 micrograms EE group compared with both 20 micrograms EE study groups. Dominant follicles (defined as follicle diameter > or = 10 mm) were observed at the end of the pill-free interval in both 20 micrograms EE groups (in 27% and 18% of women, respectively) but not in the 30 micrograms EE group. Finally, the area-under-the-curve for E2 was statistically significantly lower in the 30 micrograms EE group compared with both 20 micrograms EE groups. In conclusion, the EE content rather than the progestin component in the studied COC determined the extent of residual ovarian activity at the beginning of the pill-free interval. Dominant follicles were encountered only in the 20 micrograms EE study groups.


PIP: This article reports on a study that evaluated pituitary-ovarian recovery in the pill-free interval during a period of use of one of three low-dose combined oral contraceptives (COC). 44 female volunteers using low-dose oral contraception were subdivided into three groups in this comparative study: 15 women used 20 mcg ethinyl estradiol (EE) + 75 mcg gestodene; 17 used 20 mcg EE + 150 mcg desogestrel; 12 used 30 mcg EE + 150 mcg desogestrel. No ovulations were observed. Pituitary hormone levels between the study groups were not significantly different at the beginning of the pill-free interval. Follicle-stimulating hormone (FSH) concentrations were significantly higher at the end of the pill-free interval in the 30 mcg EE group than in both 20 mcg EE groups. In each of the 20 mcg EE groups, a single persistent follicle (24 mm and 28 mm, respectively) was found in 1 subject. In conclusion, the EE content rather than the progestin component in the studied COC determined the extent of residual ovarian activity at the beginning of the pill-free interval.

RESUMO

The validity of the cumulative pregnancy rate (CPR) calculated by life-table approach, obtained in a transport in-vitro fertilization (IVF) programme, was tested by the determination of possible influence of selective drop-out of patients with a poor treatment prognosis. A cohort of 1211 patients who had a first IVF cycle was followed, and the CPR after three IVF cycles was assessed. First cycles of patients who discontinued treatment after failed IVF, and of those who did not achieve a pregnancy but proceeded to a subsequent cycle, were compared for fertilization rate and for occurrence of prognosticators of poor treatment outcome: oocyte yield < or =2, and replacement of <2 embryos. The CPR after three cycles was 54.9%. No differences were found in the first and second cycles of patients who continued treatment and those who dropped out. Selective drop-out of patients with a poor treatment prognosis was not found. Therefore, although calculations of CPR using life-table analysis generally overestimate the real probability of pregnancy after successive IVF cycles, the calculated CPR after three IVF cycles gives a reliable indication of the chance of occurrence of a pregnancy for the population studied.

RESUMO

PURPOSE: The chance of recurrence of poor fertilization in a second in vitro fertilization (IVF) cycle was assessed. METHODS: Total fertilization failure was defined, and the relationship between the fertilization rate and the number of motile sperm cells per milliliter of semen was assessed. Patients with a total fertilization failure or poor fertilization (20% or less of the oocytes fertilized) were divided into three subgroups with different chances of fertilization and were followed in a subsequent IVF cycle. RESULTS: The recurrence rate of total fertilization failure was high in all three groups (45-70%), and poor fertilization frequently occurred in the second cycle (50-75%). CONCLUSIONS: Poor fertilization frequently recurs in the second IVF cycle. The use of intracytoplasmic sperm injection could be considered after fertilization of 20% or less of oocytes in the first cycle, irrespective of the number of motile sperm cells per milliliter of semen.

RESUMO

OBJECTIVE: To investigate whether the incidence and obstetric outcome of triplet pregnancies after IVF treatment justify strict limitation of the number of embryos to be replaced to two. DESIGN: Retrospective analysis. SETTING: A transport IVF program. PATIENT(S): All patients who had more than one embryo replaced. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Obstetric outcome, pregnancy. RESULT(S): High-order pregnancies occurred in 24 cases (23 triplets and 1 quadruplet). Three patients opted for selective embryo reduction (12.5%). Three triplet pregnancies spontaneously reduced to twins. Comparison of 18 triplets, reaching at least 20 weeks' gestation, with 54 twin pregnancies shows a higher perinatal mortality in the triplet group, causing 6 out of 18 patients to be confronted with at least one perinatal death. Triplets were born at a lower gestational age, had a lower birth weight, and a higher hospital admission rate of longer duration. Replacement of two, three, or four embryos did not lead to differences in pregnancy rates in the population studied. When a pregnancy occurred after replacement of three embryos, the risk of having a triplet pregnancy was 7.5%. CONCLUSION(S): The obstetric outcome of triplet pregnancies in our population indicates that triplet pregnancies after IVF treatment have to be prevented. Selective embryo reduction is acceptable for few patients only and can therefore not be seen as a solution. Replacement of three embryos results in triplet pregnancy in an unacceptably high percentage. Replacement of two embryos only gives acceptable IVF results and is the method chosen in the IVF program in Rotterdam to prevent triplet pregnancies.

RESUMO

OBJECTIVE: To determine whether age or response to controlled ovarian hyperstimulation (COH) is a better predictor of IVF outcome in women > or = 40 years. DESIGN: Retrospective analysis. SETTING: A transport IVF program. PATIENT(S): For patients undergoing IVF treatment the correlation between treatment outcome and age and response to COH was analyzed using the data of 2,588 consecutive cycles. INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Pregnancy. RESULT(S): The incidence of poor ovarian response rises significantly with increasing age. Analysis of all cycles showed a significant decrease in clinical and ongoing pregnancy rate for women > or = 40 years. Analysis of cycles with a good ovarian response showed no statistically significant differences for these parameters between women > or = 40 years and those younger. A logistic regression analysis on pregnancy showed that ovarian response contributes more to the prediction of pregnancy than age. CONCLUSION(S): Patients aged > or = 40 years with a good response to COH have a good prognosis for IVF treatment. The age limit for acceptance of patients should not be set at 40 years. Instead, the response to COH can be used to predict candidates likely to have a successful IVF outcome.

RESUMO

OBJECTIVE: To investigate the feasibility of IVF treatment with minimal monitoring during ovarian hyperstimulation. DESIGN: Retrospective analysis and prospective study with real-time control group. SETTING: Transport IVF program with transport clinic and satellite clinics. PATIENTS: One hundred consecutive IVF cycles monitored at a transport clinic and 100 concurrent consecutive cycles monitored at satellite clinics, using the same stimulation-monitoring protocol and resulting in oocyte aspiration, are compared retrospectively for the number of ultrasound (US) measurements carried out during monitoring and for results of IVF treatment. No patient selection took place. After introduction of a minimal monitoring protocol at a transport clinic, a prospective study was started comparing 100 minimal monitoring cycles at a transport clinic with 100 concurrent conventional monitoring cycles at satellite clinics, all resulting in oocyte aspiration. Patients entered the retrospective or prospective study only once. In all cases the same laboratory facility was used. Monitoring of ovarian hyperstimulation was done with US measurements only. Cycles were canceled for impending ovarian hyperstimulation syndrome (OHSS) when > 35 follicles were seen to develop during hyperstimulation. RESULTS: Retrospective analysis shows no difference for the average number of US measurements at transport and satellite clinics (2.8 +/- 0.9 and 3.0 +/- 1.0; mean +/- SD). No differences were found in the number of ongoing pregnancies obtained in the two groups: 22 and 18, respectively. One case of severe OHSS occurred in the satellite clinic group. Introduction of minimal monitoring at the transport clinic gives a significant reduction of the average number of US measurements at the transport clinic compared with satellite clinics, where conventional monitoring continued to be used (1.5 +/- 0.8 versus 2.8 +/- 0.9). Ongoing pregnancies at transport and satellite clinics numbered 33 and 26, respectively. In both groups one patient developed severe OHSS. Sixty-two percent of cycles at the transport clinic were monitored with one US measurement only. No cancellations for impending OHSS occurred during the study period. CONCLUSION: A large group of patients need only one US measurement during monitoring of ovarian hyperstimulation. Minimal monitoring gives a useful further simplification of the clinical phase of IVF treatment, without adverse effects on treatment outcome and incidence of OHSS.

RESUMO

OBJECTIVES: To compare efficacy, acceptability and patient preference of a single oral dose of fluconazole with a single intravaginal dose of 500 mg clotrimazole (medication groups) in women with vaginal candidosis visiting gynaecologists or general practitioners (study groups). DESIGN: A comparative, randomized multicenter study. EVENTS: Baseline visit and treatment, short-term follow-up after 1 week and long-term follow-up after 4 weeks. At each visit, symptoms were graded and cultures were obtained. RESULTS: Symptomatic and mycological efficacy did not differ statistical significant in the medication groups or study groups. A complicated history regarding vaginal candidosis was more often found among gynaecologists, yielding poorer results of treatment. Patients preferred oral treatment over intra-vaginal treatment. CONCLUSIONS: No differences were found in the clinical and mycological efficacy of both drugs. Clinical results were related to parameters originating from the patients history, resulting in less favourable results in the study group of gynaecologists.

RESUMO

A case report is presented in which a triplet pregnancy ended in an immature delivery of triplet A at 20 weeks gestation, followed by a successful delay in delivery of 49 days of triplets B and C by means of a cervical cerclage and tocolysis. This is the first reported case in which two living infants could be vaginally delivered after a preceding vaginal delivery of the third infant in a triplet pregnancy.

RESUMO

Fluor vaginalis may have a diversity of causes, among which are fungal infections by Candida spp. It has been estimated that up to 75% of women will have at least one episode of vaginal candidosis during their reproductive years. Most of these women have had only one occasional episode of discomfort. However, a small group presents with a chronic recurrence of vaginal candidosis accompanied by symptomatic infections many times a year. Until now, investigations into the pathogenesis and treatment of these recurrent episodes gave no clear answer to the question as to why this occurs in these patients. The opportunity to treat vaginal candidosis with a systemic antifungal drug can have advantages over a topical drug, if extravaginal Candida spp. that may contribute to recurrence can be eliminated at the same time. In this trial, 18 patients with chronic recurrent vaginal candidosis (greater than 4 attacks of candidosis vaginalis per year) were treated with itraconazole 200 mg/day monthly for two days--Days 5 and 6 after menstruation. After the first therapeutic treatment, 17 patients were culture-negative and symptom-free. Results show that prophylaxis for six months with itraconazole was beneficial, as far as complaints were concerned, in 11 patients (64.7%).

RESUMO

Research into the pathogenesis and treatment of chronic recurrent candidosis vaginalis did not come up with a clear answer of curing this phenomenon. In this investigation, data are presented of a therapy with a new antifungal agent, itraconazole. After a therapeutic treatment course, 17 patients received a prophylaxis for CRCV over 6 months. The treatment schedule for prophylaxis consisted of 4 capsules of 50 mg itraconazole on day 5 and 6 of the menstrual cycle. Eleven remained symptom-free in this period. Although there is no explanation for recurrence in most cases of CRCV, intermittent treatment schedules can be used to treat but not to cure these patients. Data of this investigation and data mentioned in the literature prove the necessity to discriminate between a sympatomtic and a mycological cure.

RESUMO

OBJECTIVES: To compare efficacy, safety and patient preference of a single oral dose of 150 mg fluconazole with a single intravaginal dose of 1200 mg miconazole in vaginal candidosis. To investigate the effect of treatment on Candida colonization of throat and rectum. DESIGN: Double-blind, double-dummy, parallel, randomized trial. Ninety-nine patients with symptomatic and mycologically verified candidosis were given 150 mg fluconazole with an intravaginal dummy, or 1200 mg miconazole with an oral dummy. Patients with an inadequate short-term response were given a second dose. RESULTS: At each visit a patient self assessment and an investigators' global assessment were recorded, and cultures were set up. Adverse events were recorded and laboratory tests were performed. Clinical cure or improvement (investigators' assessment) was obtained in 100% (short-term) and 95% (long term) of the fluconazole group and in 94% and 90%, respectively, of the miconazole group. Patients considered the treatment excellent or good in 81% (short-term) and 88% (long-term) in the fluconazole group and in 84% and 76%, respectively, of the miconazole group. Mycological cure was achieved in 98% (short-term) and 73% (long-term) of the fluconazole group and in 96% and 82% respectively in the miconazole group. The differences in results were not significant. Both treatments significantly reduced the number of positive rectal cultures: neither treatment had a significant effect on throat cultures. Four percent of the patients preferred intravaginal therapy. CONCLUSION: A single dose fluconazole is as safe and effective as a single dose of miconazole.
