Inadvertent oral administration of methylergometrine maleate to children in the first months of life: from surveillance to prevention.

PURPOSE: Methylergometrine maleate is an ergot alkaloid frequently used in obstetrics for prevention and treatment of post partum haemorrhage. Accidental administration of this medicine to newborns can cause severe effects and should be carefully prevented. The present paper is aimed at describing the main characteristics of cases accidentally exposed to this medicine in Italy before and after Novartis, the manufacturer of Methergin®, a widely used methylergometrine maleate-containing gynecological medication, decided to withdraw the drop preparation from the European market. METHODS: The study design is a case-series study. The database of the National Poison Control Centre of Milan was searched retrospectively (from 1 January 2005 to 31 December 2011) and prospectively (from 1 January 2012 to 31 December 2013) in order to provide a descriptive analysis of the main characteristics of cases unintentionally exposed to methylergometrine maleate and to document the impact of Novartis' decision. RESULTS: In the first period under study (2005-2011), a total of 642 cases of exposure to methylergometrine maleate were identified. Most of them were children aged <1 year (No. 483, 75%). Patients aged 1-2 and 3-5 years accounted for 13% (No. 85) and 9% (No. 56) of cases, respectively. Among children aged <1 year, about 76% (No. 368) were exposed during the first month of life, including 44% (No. 211) of cases exposed in the first week of life. The main cause of exposure was medication error (No. 432, 89%), mainly due to oral administration of methyltergometrine maleate in place of a paediatric preparation (No. 469, 97%). About 14% of these cases suffered clinical effects as a consequence of the exposure. Severity of poisoning was minor in 45 cases, moderate in 12, and severe in one case. The main cause of exposure among children aged 1-2 and 3-5 years was uncontrolled access to the medicine, accounting for 78% (No. 66) and 77% (No. 43) of cases, respectively. Some 9% (No. 8) of cases aged 1-2 years and 7% (No. 4) of those aged 3-5 years developed signs/symptoms possibly related to the exposure. For all of them, severity of clinical effects was low, but one case suffered moderate effects. Exposure to the medicine in drops was reported for 87% (No. 74) and 84% (No. 47) of cases aged 1-2 and 3-5 years, respectively. In 2012-2013 a total of 25 cases were observed. Among them, two patients were aged <1 year (8%). Both cases occurred in 2012 and were inadvertently administered the medicine in drops still available (present) in the home. Fourteen (56%) and 8 (32%) cases were aged 1-2 and 3-5 years, respectively. All of them were exposed to the tablet formulation following uncontrolled access to the medicine. CONCLUSIONS: The observations here reported indicate that having different formulations for methylergometrine maleate-containing products intended for the mother and paediatric medicines can successfully prevent medication error due to medicine exchange in the first months of life.

Drug-induced anaemia: a decade review of reporting to the Italian Pharmacovigilance data-base.

BACKGROUND: Studies investigating drug-induced anaemia are relatively scarce and mostly related to specific drugs or patients with specific pathologies. OBJECTIVE: To analyse all reports of suspected drug-induced anaemias recorded in the National Pharmacovigilance Database of the Italian Medicines Agency. METHOD: The cases of suspected drug-induced anaemias analysed were those retrieved from the Italian National Pharmacovigilance Database from January 2001 to December 2013. RESULTS: The active substances involved were 375 in 3,305 reports of drug-induced anaemia; of these, 72 % were reported as serious. In 35 % of the reports patients were in polytherapy. In 24.3 % of the cases relevant DDIs were identified. We found a PRR value of 57.29 for peginterferon alfa-2a, of 12.57 for ribavirin, of 13 for flu vaccine for the occurrence of autoimmune haemolytic anaemia. The drugs mostly involved in the cases where the Naranjo causality was probable or possible were acetylsalicylic acid, warfarin, ribavirin, peginterferon alfa-2a, carboplatin and acenocoumarol. CONCLUSIONS: A possible signal was detected for peginterferon alfa-2a, ribavirin and flu vaccine in the occurrence of autoimmune haemolytic anaemia. A great involvement of clopidogrel, enoxaparin, warfarin, ticlopidine and acetylsalicylic acid in preventable DDI-induced anaemia was detected, highlighting a poor awareness among healthcare providers on this issue.

α1-Adrenergic receptor antagonists and gynecomastia. A case series from the Italian spontaneous reporting system and VigiBase(™).

PURPOSE: The aim of this study was to analyze the cases of gynecomastia associated with α1A-adrenergic receptor antagonists (α1-ARAs) in the Italian spontaneous reporting system database (Rete Nazionale di Farmacovigilanza or RNF) and in the World Health Organization ICSRs database (VigiBase(™)), focusing on tamsulosin use. METHODS: We analyzed the spontaneous reports of gynecomastia related to the use of α1-ARAs and collected from the RNF and from VigiBase(™) up to December 2012. Cases of gynecomastia have been defined as reports associated with gynecomastia according with Medical Dictionary for Regulatory Activities (MedDRA). Reporting odds ratio (ROR) and Information Component (IC) were calculated as measures of disproportionality in RNF and VigiBase(™), respectively. RESULTS: Up to December 2012, about 186,000 reports were recorded in the RNF. Among these, 902 reports of adverse drug reaction (ADR) have been associated with the use of at least one α1-ARAs. Of these, in 15 cases, gynecomastia was a listed ADR: in 10, the suspected drug was tamsulosin (in eight, it was the sole suspect); in two, doxazosin and alfuzosin, respectively; and in one, terazosin. ROR for tamsulosin was 5.3 (95% CI 1.8, 15.7). In VigiBase(™), 84 reports of gynecomastia indicated tamsulosin as suspected drug. Tamsulosin-associated gynecomastia showed the highest IC value within this class of drugs (IC 95% 2.43). CONCLUSION: In this study, we highlight a possible association between gynecomastia and tamsulosin use. To our knowledge, this association has not been described before and could represent a potential signal.

Oral ingestion of a topical benzydamine hydrochloride-containing gynaecological preparation in association with television advertising in Italy: analysis of cases managed by a National Poison Control Centre.

Objective To evaluate the impact of a television advertising campaign on the risk of oral ingestion of a topical non-prescription gynaecological preparation containing benzydamine hydrochloride. Design An interrupted time series design with data routinely collected. Setting A National Poison Control Centre. Participants 215 cases of hazardous exposure to the preparation under study occurred in Italy from January 2005 to December 2010. Primary and secondary outcome measures Mean daily rate of cases of exposure by gender in three different periods, that is, pre-advertisement period, before the advertisement was broadcast (from 1 January 2005 to 19 December 2009), advertisement period, when the advertisement was repeatedly launched (from 20 December 2009 to 27 February 2010), post-advertisement period (from 28 February 2010 to 6 March 2010); observed/expected ratios of cases, with expected cases based on data from the pre-advertisement period, adjusted for estimated variations in the number of users. Comparison of the distribution of the main characteristics of cases in the three different periods by means of Pearson's χ(2) test or Fisher's exact test. Results The adjusted observed/expected ratio of cases in women was 7.48 (95% CI 5.76 to 9.56) in the advertisement period and 2.97 (95% CI 2.24 to 3.85) in the post-advertisement period. Regarding the characteristics of cases, there was an increased proportion of cases of exposure due to confusion about the correct administration route in the advertisement and post-advertisement periods (81% and 55%, respectively, compared to 16% for the pre-advertisement period.) and of individuals with clinical effects (55%, 52% and 27%, respectively). Conclusions In Italy, an advertisement for a non-prescription medicine seems to have confused consumers regarding the administration route. This effect was observed even after the advertisement had stopped being broadcast. These results highlight the need for the monitoring of medication errors and adverse effects before, during and after advertising.

An infertile couple suffering from oligospermia by partial sperm maturation arrest: can phytoestrogens play a therapeutic role? A case report study.

We describe the case of a 30-year-old man with severe oligospermia, caused by partial sperm maturation arrest at spermatidic stage, who was given phytoestrogens. The couple had been trying to conceive for 3 years. The woman was normal at the clinical and endocrinological examination. No other parameters except sperm count, motility and morphology were altered in the male subject. Semen analysis was performed at baseline and after 3 and 6 months of therapy, which consisted of phytoestrogens 80 mg/day for 6 months. An additional semen analysis was performed 6 months after the termination of therapy (wash-out period). During the third month semen parameters improved drastically; therefore a reproductive technique (intrauterine insemination) was performed. This treatment resulted in pregnancy, and a healthy baby weighing 3300 g was born. After 6 months of treatment, sperm parameters ameliorated further. Conversely, after the wash-out period, they returned to baseline values. The appealing results strongly suggest a therapeutic role for phytoestrogens in the treatment of oligospermia. However, it is evident that a validation stage and randomized, controlled studies are essential in order to confirm this observation and verify that phytoestrogens can play an important role in male infertility.

Effects of the position of fibroids on fertility.

This prospective, controlled study was performed in order to evaluate whether the location of uterine fibroids may influence reproductive function in women and whether removal of the fibroid prior to conception may improve pregnancy rate and pregnancy maintenance. We examined 181 women affected by uterine fibroids who had been trying to conceive for at least 1 year without success. The main outcome measures were the pregnancy rate and the miscarriage rate. Among the patients who underwent myomectomy, the pregnancy rates obtained were 43.3% in cases of submucosal, 56.5% in cases of intramural, 40.0% in cases of submucosal-intramural and 35.5% in cases of intramural-subserosal uterine fibroids, respectively. Among the patients who did not undergo surgical treatment, the pregnancy rates obtained were 27.2% in women with submucosal, 41.0% in women with intramural, 15.0% in women with submucosal-intramural and 21.43% in women with intramural-subserosal uterine fibroids, respectively. Although the results were not statistically significant in the group of women with intramural and intramural-subserosal fibroids, this study confirms the important role of the position of the uterine fibroid in infertility as well as the importance of fibroids removal before the achievement of a pregnancy, to improve both the chances of fertilization and pregnancy maintenance.

Psychological assessment of the effects of treatment with phytoestrogens on postmenopausal women: a randomized, double-blind, crossover, placebo-controlled study.

OBJECTIVE: To investigate the effects of soy isoflavones on mood and cognitive function in postmenopausal women. DESIGN: Randomized, double-blind, cross-over, placebo-controlled trial. SETTING: University Hospital, Milan, Italy; A.G.UN.CO. Obstetrics and Gynaecology Centre, Rome, Italy. PATIENT(S): Seventy-eight postmenopausal women. INTERVENTION(S): We administered 60 mg/day isoflavones or placebo for 6 months. After a washout period of 1 month, the patients who had been treated with phytoestrogens received placebo, and those who previously received placebo were administered phytoestrogens (for 6 months). MAIN OUTCOME MEASURE(S): Cognitive performance and mood were assessed by a battery of tests at the end of each treatment period. At the end of the study, the patients were also asked whether they preferred the first or second treatment. RESULT(S): The 17 scores on cognitive performance test and the 6 for mood assessments 6 showed an advantage for the treatment with phytoestrogens. Similarly, of the 8 visual analogue scales used to indicate mood, 7 improved significantly after the treatment with phytoestrogens. Moreover, 49 patients preferred phytoestrogens, 9 placebo, and 18 had no preference. The preference was not related to the order of treatment. CONCLUSION(S): These results suggest that isoflavones may have positive effects on postmenopausal women improving cognitive performance and mood.

Efficacy and safety of 17alpha-hydroxyprogesterone caproate in hormone replacement therapy.

The aim of the present study was to evaluate the efficacy (in terms of induction of uterine bleeding) and safety (in terms of absence of endometrial hyperplasia) of 17alpha-hydroxyprogesterone caproate (17alpha-HPC) in a therapeutic regimen for hormonal replacement after menopause. Fifty postmenopausal patients received hormone replacement therapy (HRT) for 24 weeks. The treatment regimen consisted of standard estrogen replacement therapy at commonly prescribed doses for the prevention of climacteric symptoms and 341 mg of 17alpha-HPC every 30 days. Enrolled women were told to expect withdrawal bleeding 7-10 days after the administration of 17alpha-HPC. Forty-eight patients completed the trial. In 91.7% of cases, patients experienced the expected pattern, i.e., strict withdrawal bleeding exclusive of any other form of bleeding. Breakthrough bleeding and/or other forms of abnormal bleeding affected only four women. At the 6th month none of the endometrial samplings motivated by endometrial thickness >10 mm and evidence of heterogeneous echogenicity (two cases) was positive for carcinoma. No biopsies had to be performed at the end of the 12th month of treatment. No serious adverse effect where recorded during the study period. In conclusion, our data show the efficacy and safety of 17alpha-HPC in HRT.

Diclofenac pyrrolidine versus Ketoprofen for the relief of pain from episiotomy: a randomized controlled trial.

BACKGROUND: The treatment of pain from episiotomy or from tearing of perineal tissues during childbirth is often unapplied, although discomfort may be severe. We performed a randomized double-blind controlled trial to compare the effectiveness and side-effects of two analgesics in the management of postpartum perineal pain. Patient preference toward the two medications was also analyzed. METHODS: A total of 261 women were randomly assigned to receive either Diclofenac hydroxyethyl pyrrolidine (100 mg) (n = 133) or Ketoprofen (100 mg) (n = 128), both given orally every 12 hr up to 48 hr, as necessary. Inclusion criteria were vaginal birth with episiotomy and/or a second- to third-degree tear. Pain ratings were recorded before the administration of the drugs and at 1, 4, 12, and 24 hr after the first dose, according to a 10-cm visual-analog scale. Side-effects and overall opinion on the two treatments were assessed at 24 hr. RESULTS: Diclofenac hydroxyethyl pyrrolidine and Ketoprofen had similar analgesic properties in the first 24 hr postpartum [mean pain rating 3.1 +/- 1.8 and 3.4 +/- 2.0, mean number of doses in 24 hr 1.4 +/- 1.4 and 1.3 +/- 1.5, and proportion of treatment failures 12.8% (17/133) and 16.4% (21/128), respectively]. Significantly fewer subjects in the Diclofenac hydroxyethyl pyrrolidine group than in the Ketoprofen group experienced side-effects (6.8% versus 15.6%; p = 0.038) with an odd risk = 0.39(95% C.I. 0.16-0.95). There were no significant differences in overall patient satisfaction between the two groups. CONCLUSIONS: No main differences were found concerning the relief of pain between the two treatments. Diclofenac hydroxyethyl pyrrolidine may be the preferred choice because it is associated with less adverse reactions, together with a faster action in the relief of pain.

Different routes of progesterone administration and polycystic ovary syndrome: a review of the literature.

Polycystic ovary syndrome (PCOS) is a common endocrine disorder in woman of reproductive age. Although extensive studies have been performed in past decades to investigate the pathobiological mechanisms underlying the unset of this disease, its etiology remains unknown. Progesterone is a hormone of paramount importance in ovulation, implantation and luteal phase support. Low levels of progesterone have been found in the early luteal phase in PCOS patients. Granulosa cells from polycystic ovaries show an altered progesterone production. Moreover, the lack of cyclical exposure to progesterone may have a role in the development of the gonadotropin and androgen abnormalities found in PCOS patients. Ovulation failure and progesterone deficiency may facilitate the hypothalamic-pituitary abnormalities causing the associated disordered luteinizing hormone secretion in PCOS. Progesterone may be administered to PCOS patients in the following cases: to induce withdrawal bleeding, to suppress secretion of luteinizing hormone, in ovulation induction in clomiphene citrate-resistant patients and in luteal phase support in assisted reproduction. We discuss the pharmacologic characteristics of the different routes of progesterone administration with reference to these diverse indications, the therapeutic objectives and patient compliance.

Ovulation induction with urinary FSH or recombinant FSH in polycystic ovary syndrome patients: a prospective randomized analysis of cost-effectiveness.

The aim of this prospective, randomized trial was to compare the clinical results and the cost-effectiveness of urinary FSH (uFSH) and recombinant FSH (rFSH) in ovarian stimulation for intrauterine insemination (IUI) cycles in polycystic ovary syndrome (PCOS) patients. One-hundred and seventy PCOS infertile patients undergoing IUI were enrolled, and protocols of ovarian stimulation with uFSH or rFSH were randomly assigned. The total number of cycles performed was 379 (182 and 197, respectively). The main outcome measures were the number of mature follicles, the days of stimulation, the number of ampoules and IU used per cycle, the biochemical/clinical pregnancy rates, the number of multiple pregnancies and the cost-effectiveness. No statistically significant differences were found in the follicular development, length of stimulation, pregnancy rates, delivery rates and multiple pregnancies between the two groups. In the uFSH group, the cost per cycle remained significantly lower (218.51 +/- 88.69 versus 312.22 +/- 118.12; P < 0.0001), even though a significantly higher number of IU of gonadotrophins were used (809.3 +/- 271.9 versus 589.1 +/- 244.7; P < 0.0001). The cost-effectiveness (i. e. within a group, the total cost of all cycles divided by no. of clinical pregnancies) was 1729.08 in the uFSH group and 3075.37 in the rFSH group. In conclusion, uFSH and rFSH demonstrated the same effectiveness in ovarian stimulation in IUI cycles in PCOS patients. The urinary preparation is more cost-effective due to the difference of its cost per IU.

Phytoestrogens may improve the pregnancy rate in in vitro fertilization-embryo transfer cycles: a prospective, controlled, randomized trial.

OBJECTIVE: To compare the effectiveness of i.m. P and i.m. P plus oral phytoestrogens for luteal phase support in patients undergoing IVF-ET cycles. DESIGN: Prospective, controlled, randomized trial. SETTING: University Hospital, Perugia, Italy. PATIENT(S): Two hundred thirteen infertile patients undergoing IVF-ET were included in the study. The inclusion criteria were use of a GnRH agonist for pituitary down-regulation and age <40 years. The total number of cycles performed was 274. INTERVENTION(S): Patients were assigned to receive either i.m. P (50 mg daily) plus placebo or P (50 mg daily) plus phytoestrogen supplementation (1,500 mg daily) for luteal phase support starting from the evening of oocyte retrieval until either a serum pregnancy test result was negative or embryonic heartbeat was sonographically confirmed. MAIN OUTCOME MEASURE(S): The outcomes of IVF-ET were evaluated in both study groups in terms of implantation rate, biochemical pregnancy rate (PR), clinical PR, spontaneous abortion rate, and ongoing pregnancy/delivered rate. RESULT(S): Statistically significant higher values for implantation rate, clinical PR, and ongoing pregnancy/delivered rate were recorded in the patients who received P plus phytoestrogens for luteal phase support in comparison with patients receiving P and placebo. CONCLUSION(S): Although the results of this study encourage the use of phytoestrogens for luteal phase support in patients undergoing IVF-ET program, more studies are necessary to support the hypothesis that phytoestrogens have a beneficial effect in IVF cycles.

Recombinant versus urinary follicle-stimulating hormone in intrauterine insemination cycles: a prospective, randomized analysis of cost effectiveness.

OBJECTIVE: To compare the clinical results and the cost effectiveness of urinary FSH and recombinant FSH in ovarian stimulation for IUI cycles. DESIGN: Prospective, randomized trial. SETTING: University Hospital, Perugia, and A.G.UN.CO. Obstetrics and Gynaecology Centre, Rome, Italy. PATIENT(S): IUI cycles were performed in 67 infertile patients. INTERVENTION(S): Protocols of ovarian stimulation with urinary FSH or recombinant FSH were randomly assigned, for a total of 138 cycles performed (67 and 71, respectively). MAIN OUTCOME MEASURE(S): Number of mature follicles, days of stimulation, number of ampules, and IU used per cycle, biochemical/clinical pregnancy rates and cost-effectiveness ratio. RESULT(S): Follicular development, length of stimulation, pregnancy and delivery rates were not statistically different. Although in the urinary FSH group a significantly higher number of IU of gonadotropins were used (815.5 +/- 284.9 vs. 596.0 +/- 253.8), the cost per cycle remained significantly lower (220.73 +/- 94.72 vs. 318.50 +/- 125.21). The cost-effectiveness ratio was 1,848.61 euro in the urinary FSH group and 2,512.61 euro in the recombinant FSH group. CONCLUSION(S): Urinary FSH and recombinant FSH are both effective in ovarian stimulation in IUI cycles. The urinary preparation is more cost effective due to the difference of its cost per IU.

Endometrial effects of long-term treatment with phytoestrogens: a randomized, double-blind, placebo-controlled study.

OBJECTIVE: To determine the effects of 5 years of treatment with soy phytoestrogens on histological characteristics of endometrium in postmenopausal women. DESIGN: Randomized, double-blind, placebo-controlled study. SETTING: Centre of Perinatal and Reproductive Medicine, Department of Gynecological, Obstetrical, and Pediatric Sciences, University of Perugia, Italy. PATIENT(S): Three hundred seventy-six postmenopausal healthy women, all with intact uterus. INTERVENTION(S): Women were distributed in two different groups using randomized criteria: group A (n = 179) patients received soy tablets (150 mg of isoflavones per day) for 5 years; group B (n = 197) patients received identical appearing placebo tablets for 5 years. MAIN OUTCOME MEASURE(S): Results of endometrial histology from biopsies obtained at baseline, 30 months, and 5 years after the beginning of the treatment. RESULT(S): Two hundred ninety-eight women completed the 5-year treatment. No cases of malignancy were detected during biopsy. Seventy percent of women undergoing treatment with soy phytoestrogens had an endometrium classified as atrophic or nonassessable versus 81% receiving placebo. The occurrence of endometrial hyperplasia was significantly higher in group A (3.37% vs. 0%). CONCLUSION(S): Long-term treatment (up to 5 years) with soy phytoestrogens was associated with an increased occurrence of endometrial hyperplasia. These findings call into question the long-term safety of phytoestrogens with regard to the endometrium.

17 alpha-hydroxyprogesterone caproate versus intravaginal progesterone in IVF-embryo transfer cycles: a prospective randomized study.

One of the main issues in the management of IVF and embryo transfer techniques is to ensure adequate concentrations of progesterone. The aim of this prospective, randomized study was to compare the effectiveness of 17 alpha -hydroxyprogesterone caproate (17-HPC) administered intramuscularly and intra-vaginal progesterone in gel in luteal phase support in patients undergoing IVF-embryo transfer cycles. A total of 320 patients were randomly treated with either 17-HPC (341 mg i. m. every 3 days) or progesterone vaginal gel (90 mg daily). The inclusion criteria were the use of gonadotrophin-releasing hormone down-regulation and age <40 years. The outcome of IVF in both study groups was evaluated for implantation rate, biochemical pregnancy, clinical pregnancy, miscarriage, and ongoing pregnancy rate. The results of this study showed that 17-HPC conferred more benefit to IVF-embryo transfer cycles compared with intra-vaginal progesterone, as demonstrated by the results of most of the main outcome parameters considered. The data showed that 17-HPC administered every 3 days appears to be more effective in providing luteal support in comparison to intra-vaginal progesterone.

High dose of phytoestrogens can reverse the antiestrogenic effects of clomiphene citrate on the endometrium in patients undergoing intrauterine insemination: a randomized trial.

OBJECTIVE: To compare the effectiveness of clomiphene citrate (CC) alone or combined with phytoestrogens (PE) in ovulation induction in patients who had intrauterine insemination in a randomized, double-blind study. METHODS: A total of 134 women aged 25-35 years, who were infertile for at least 2 years and who had oligomenorrhea or amenorrhea associated with a positive menstrual response to the intramuscular progesterone-challenge test were enrolled. They were randomly treated with CC (100 mg daily for 5 days) and CC (100 mg daily for 5 days) in combination with PE (1500 mg daily for 10 days). We estimated the difference in uterine artery pulsatily index, number of preovulatory follicles, endometrial thickness, and pregnancy rate. RESULTS: Both treatments increased follicle-stimulating hormone, luteinizing hormone, and 17beta-estradiol plasma concentrations, but the differences were not statistically significant. However, the differences in endometrial thickness of the two groups were statistically significant. No significant differences in the pulsatility index values and in the number of preovulatory follicles were noted. CONCLUSION: A high dose of phytoestrogens can reverse the deleterious effects of clomiphene citrate on endometrial thickness and could contribute to higher pregnancy rates.
