The Role of Micronutrients in Human Papillomavirus Infection, Cervical Dysplasia, and Neoplasm.

There is evidence that diet and nutrition are modifiable risk factors for several cancers. In recent years, attention paid to micronutrients in gynecology has increased, especially regarding Human papillomavirus (HPV) infection. We performed a review of the literature up until December 2022, aiming to clarify the effects of micronutrients, minerals, and vitamins on the history of HPV infection and the development of cervical cancer. We included studies having as their primary objective the evaluation of dietary supplements, in particular calcium; zinc; iron; selenium; carotenoids; and vitamins A, B12, C, D, E, and K. Different oligo-elements and micronutrients demonstrated a potential protective role against cervical cancer by intervening in different stages of the natural history of HPV infection, development of cervical dysplasia, and invasive disease. Healthcare providers should be aware of and incorporate the literature evidence in counseling, although the low quality of evidence provided by available studies recommends further well-designed investigations to give clear indications for clinical practice.

Needlestick injuries among obstetrics and gynecology trainees: A survey study.

OBJECTIVE: To assess characteristics, incidence, risk factors, and reporting rate of needlestick injuries (NSIs) among Obstetrics and Gynecology trainees. STUDY DESIGN: We performed a nationwide cross-sectional survey study. The 40-items survey Obstetrics Needlestick Injury Questionnaire (ONSI-Q) was used to investigate the prevalence of NSIs, participant attitudes, associated factors, and the NSI reporting rate among trainees in Obstetrics and Gynecology. The target responders were all trainees of Obstetrics and Gynecology training programs in Italy. The trainees were invited between September 2018 and December 2018 via a web-based platform. RESULTS: Among 1049 trainees, 1041 (99.2%) completed the survey. Out of 1041 trainees, 639 (61.4%) had at least one NSI, and 90.9% (581/639) experienced at least one during obstetric surgery. The number of NSIs increased with the year of training, with 2.48 NSIs per trainee in the fifth year. 90.6% (579/639) reported details about the most recent NSI, which was during obstetric surgery in 95.3% (552/579) of cases. 57.1% (315/552) experienced the most recent NSI during cesarean section, which was mainly inflicted by someone else (72.4%; 228/315). 42.9% (237/552) of NSIs were during perineal suture, and 84% (199/237) of them were self-inflicted. 77.9% (417/535) of trainees did not report the NSI. Associated factors were non-high-risk patients, self-inflicted NSI, and the first NSI. CONCLUSIONS: NSIs are frequent among Obstetrics and Gynecology trainees but not reported, and obstetric surgery is the primary source. These data support the European efforts to improve working practices' safety. The education about protective strategies and reporting should be a priority.

Fertility and reproductive outcome after tubal ectopic pregnancy: comparison among methotrexate, surgery and expectant management.

PURPOSE: To compare fertility and reproductive outcome after surgical, medical, and expectant management for tubal ectopic pregnancy (EP). METHODS: 133 of 228 patients, who were managed between January 2012 and December 2017 for a tubal EP, tried to conceive immediately after treatment: 86 out of 173 (49.7%) underwent surgical treatment; 38 (21.9%) were treated with methotrexate (MTX), and 49 (28.3%) had expectant management. Clinical data were retrieved by medical records, fertility outcomes were obtained by phone follow-up. The cumulative incidence (CI) of intrauterine clinical pregnancy (CP), miscarriage, live birth (LB), and recurrent EP, and the time between treatment and first intrauterine CP were compared between women treated with MTX, surgery and expectant management. RESULTS: The CI of intrauterine CP starting from 12 months after the EP was 65.3% for the expectant management, 55.3% for the MTX group, and 39.5% for surgery (p = 0.012). Post-hoc analysis showed expectant management having higher intrauterine CP and LB, and shorter time between treatment and first intrauterine CP compared to surgery (p < 0.05). The CI of recurrent EP was comparable between the 3 groups. The analysis stratified per ßhCG cut-off of 1745 mUI/mL and EP mass cut-off of 25 mm reported consistent results. CONCLUSIONS: Women successfully managed by expectation appear to have better reproductive outcomes compared to women who underwent surgery, with the shortest time to achieve a subsequent intrauterine CP. Therefore, if safely applicable the expectant management should be considered in the case of tubal EP. The fact that the chosen treatment was primarily guided by the ßhCG value and EP mass diameter based on the protocol, which is intrinsically related to the characteristics of the EP, represents the main limitation of the present study. Indeed, we cannot completely exclude that the observed differences between treatments are related to the EP itself instead of the treatment.

Aromatase inhibitors for the treatment of endometriosis: a systematic review about efficacy, safety and early clinical development.

INTRODUCTION: Pharmacotherapy has a key role in endometriosis treatment and management, however, a significant proportion of patients have only intermittent or limited benefits with current treatment options. Therefore, novel therapeutic approaches are necessary. AREAS COVERED: This systematic review provides an overview of the efficacy and safety of aromatase inhibitors (AIs) as monotherapies and combination therapies for endometriosis. A systematic literature search was performed from January 1990 to April 2020 in the electronic database MEDLINE, EMBASE, The Cochrane Library, and Web of Science. EXPERT OPINION: Based on the critical role of estrogens and the rate-limiting step in the production of the estrogens represented by the aromatase enzyme, AIs are a potential therapeutic option for women affected by endometriosis. Nevertheless, further research is needed to clarify the efficacy of AIs in this setting. Adverse effects need to be investigated to clarify the preventive role of add-back therapy. On that basis, AIs should be adopted only as second-line therapy in patients who are refractory to standard treatments in the setting of scientific research. Further studies should define best dosages, appropriate add-back therapies, administration routes, treatment length, and which patients may benefit more from AIs.

Secondary and tertiary ovarian cancer recurrence: what is the best management?

Ovarian cancer with complete clinical response recurs with a high rate. Recurrence is observed in almost 25% of cases with early-stage diseases and in more than 80% with more advance stages. Based on a platinum-free interval cut-off of 6 months, the first recurrence is usually classified in platinum-sensitive versus platinum-resistant, reflecting the biological characteristics underlying the clinical behavior. After this first recurrence, the patients are rarely cured, but second-line therapy can provide significant clinical responses, particularly in first platinum-sensitive recurrence. The approach to secondary and tertiary recurrence follows the same general principles applied in the first recurrence. Platinum-sensitivity based on the treatment-free interval defines the available chemotherapeutic regimens, whit less therapeutic options and a generally worse prognosis in platinum-resistant recurrent disease. Nevertheless, in this scenario, the introduction of new targeted therapies changed the prognosis of patients with both platinum-sensitive and platinum-resistant recurrence. The first introduced antiangiogenic therapy resulted able to improve prognosis in recurrent disease both as a single-agent and combined therapy, although the growing adoption in the first line therapy requires further investigation to prove their efficacy after repeated use. More recently, the approach to secondary, tertiary, and later recurrence has been changed by the introduction of PARP inhibitors, which resulted effective as maintenance monotherapy in both platinum-sensitive and platinum-resistant recurrence when the genetic background of the tumor allows their application with a significant improvement of oncological outcomes. Overall, although the growing body of promising therapeutic options to approach recurrent ovarian cancer, all the available evidence suggests that the best unique management of secondary and tertiary recurrence does not exist but should be personalized based on the disease characteristics, previous treatments, patient characteristics, and patient preference. On that basis, in this review, we report a general and complete overview of the approach at the secondary and tertiary ovarian cancer recurrence with the aim to provide a wide vision on the multiple available therapeutic options.

Hysteroscopic Metroplasty for T-Shaped Uterus: A Systematic Review and Meta-analysis of Reproductive Outcomes.

IMPORTANCE: To date, a comprehensive review on the safety and effectiveness of hysteroscopic metroplasty for T-shaped uterus is still missing. OBJECTIVE: To provide a robust synthesis of the available studies investigating reproductive outcomes after hysteroscopic metroplasty for T-shaped uterus. EVIDENCE ACQUISITION: We performed a systematic review and meta-analysis (CRD42019143291), using the proportion method with 95% confidence interval (CI). Statistical heterogeneity was assessed by Higgins test (I2). RESULTS: We included 11 cohort studies embedding 937 women who underwent hysteroscopic metroplasty. After surgery, the pooled percentage of live birth was 44.54% (95% CI, 36.12%-53.12%; I2 = 46.22%) and 56.88% (95% CI, 46.48%-66.98%; I2 = 36.38%) in women with primary infertility and recurrent miscarriage, respectively. In women with recurrent miscarriage, the pooled proportion of miscarriage was 21.46% (95% CI, 15.09%-28.61%; I2 = 30.18%). The pooled clinical pregnancy proportion in women with primary infertility was 57.19% (95% CI, 43.83%-70.03%; I2 = 77.81%). The pooled rate of surgical complications was 0.65% (95% CI, 0.20%-1.33%; I2 = 11.44%). CONCLUSIONS: The hysteroscopic correction of T-shaped uteri was associated with high live birth rate and low miscarriage rate, both in case of primary infertility and recurrent miscarriage. RELEVANCE: Hysteroscopic metroplasty can be considered a safe and effective strategy to improve reproductive outcomes in case of T-shaped uterus.

An update on treatment options for interstitial cystitis.

Interstitial cystitis or bladder pain syndrome (IC/BPS) is a chronic pelvic pain syndrome related to the urinary bladder. The ideal treatment should match as much as possible with the pathophysiologic causes of the IC/BPS, but the scarcely available evidence limits this approach, with the majority of available treatments that are primarily targeted to the control of symptoms. The treatment strategies have traditionally focused on the bladder, which is considered the primary end-organ and source of pain. Nevertheless, the growing body of evidence suggests a multifaceted nature of the disease with systemic components. In general, guidelines recommend the personalized and progressive approach, that starts from the more conservative options and then advances toward more invasive and combined treatments. The behavioral changes represent the first and most conservative steps. They can be combined with oral medications or progressively with intravesical instillation of drugs, up to more invasive techniques in a combined way. Despite the multiple available options, the optimal treatment is not easy to be found. Only further investigation on the etiopathogenetic mechanisms, taking into account the differences among subgroups, and the interaction between central and peripherical factors may allow providing a real improvement in the treatment and management of these patients.

Aberrant Telomere Length in Circulating Cell-Free DNA as Possible Blood Biomarker with High Diagnostic Performance in Endometrial Cancer.

To investigate the diagnostic performance of relative telomere length (RTL) in cell-free DNA (cfDNA) for endometrioid endometrial cancer (EC). We measured RTL in cfDNA of 40 EC patients (65 ± 12 years) and 31 healthy controls (HC) (63 ± 13 years), excluding in both groups other oncologic and severe non-oncologic diseases to limit confounders. Circulating cfDNA was extracted from serum using the QIAamp DNA Blood Mini kit (Qiagen, Hilden, Germany). After the quantitative real-time polymerase chain reaction, telomere repeat copy number to single-gene copy number ratio was calculated. RTL in cfDNA was found to be significantly lower in EC patients than in HC (p < 0.0001). The diagnostic performance of cfDNA RTL was estimated with receiver operating characteristics (ROC) curve analysis, which showed a diagnostic accuracy for EC of 0.87 (95% CI: 0.79-0.95, p < 0.0001). The cutoff cfDNA RTL value of 2.505 (T/S copy ratio) reported a sensitivity of 80.0% (95% CI: 64.35-90.95) and a specificity of 80.65% (95% CI: 62.53-92.55). Significant differences of RTL among EC stages or grades (p = 0.85 and p = 0.89, respectively) were not observed. Our results suggest that cfDNA RTL analysis may be a diagnostic tool for EC detection since the early stage, whilst its diagnostic performance seems unsatisfactory for cancer progression, staging, and grading. However, further studies are needed to confirm these preliminary findings. In particular, future investigations should focus on high-risk patients (such as those with atypical endometrial hyperplasia) that may benefit from this tool, because TL shortening is not specific for EC and is influenced by other oncologic and non-oncologic diseases.

PET-CT scan in the preoperative workup of early stage intermediate- and high-risk endometrial cancer.

Objectives: To evaluate positron emission tomography-computed tomography (PET-CT) for the preoperative management of early-stage intermediate- and high-risk endometrial cancer (EC).Study design: Data of patients with intermediate- and high-risk early-stage EC were retrieved from a prospectively collected database. Patients with preoperative PET-CT followed by surgical staging including pelvic lymphadenectomy were analyzed. Diagnostic performance for lymph node (LN) metastasis was evaluated.Results: Overall, 45 patients were included: 27 (60%) and 18 (40%) with intermediate- and high-risk EC, respectively. Four patients (8.8%) had LN metastasis, three correctly identified at PET-CT, yielding a sensitivity of 75% (95% CI 21.9-98.7). Among 41 patients (91.2%) without LN metastasis, 38 had negative PET-CT with specificity of 92.7% (95% CI 78.9-98.1). The negative predictive value (NPV) was 97.4% (95% CI 84.9-99.9) and the positive predictive value was 50% (95% CI 13.9-86.1).Conclusions: The utility of PET-CT is limited by the low sensitivity for LN metastasis in intermediate- and high-risk early-stage EC, that may impede to consider PET-CT alone an adequate alternative to surgical retroperitoneal staging by lymphadenectomy or sentinel LN biopsy. However, the high diagnostic accuracy, specificity and NPV might support its adoption to improve the diagnostic accuracy of the sentinel LN algorithm.

Efficacy of a collagen-fibrin sealant patch (TachoSil®) as adjuvant treatment in the inguinofemoral lymphadenectomy for vulvar cancer: a double-blind randomized-controlled trial.

PURPOSE: To evaluate the effect of a collagen-fibrin sealant patch (TachoSil®) in preventing postoperative complications after inguinofemoral lymphadenectomy for vulvar cancer. METHODS: Double-blind randomized-controlled trial on consecutive patients undergoing bilateral inguinofemoral lymphadenectomy for vulvar cancer. Intraoperatively, inguinofemoral areas were randomized: one was treated with TachoSil®, while the contralateral had standard closure without collagen-fibrin sealant patch. Surgical outcomes, amount of drainage volume, duration of drain placement, and any postoperative complication (vulvar wound dehiscence, inguinal wound dehiscence, cellulitis, lymphangitis, lymphoceles, and hematoma) were recorded. Leg measurements were taken preoperatively and during postoperative follow-up until 6 months to evaluate lymphedema. RESULTS: A total of 19 patients were enrolled and 38 inguinofemoral dissections were performed. There was no significant difference between the investigational and control arm in the amount of drainage volume (p = 0.976), and duration of drain placement (p = 0.793). The postoperative complications, excluding lymphedema, were 10/19 (53%) in investigational arm and 9/19 (47%) in control arm (p = 0.74). At the end of follow-up, the prevalence of grade 1 lymphedema was 44.4% and 50% in investigational and control arm, respectively (p = 0.744); grade 2 and 3 lymphedema had a prevalence of 33.3% in both arms (p = 1). CONCLUSION: Application of TachoSil® does not seem to improve postoperative lymphorrhagia nor to reduce the incidence of postoperative complications in patients undergoing inguinofemoral lymphadenectomy for vulvar cancer. Considering this point, it would be useful to identify additional strategies in inguinofemoral dissection for the prevention of these complications.

Unintentional transvesical caesarean section: incidence, risk factors, surgical technique and post-operative management.

OBJECTIVE(S): To assess incidence, risk factors, management, and short and long-term outcomes of unintentional transvesical caesarean section (UTV-CS) defined as any extraction of the fetus through a double full thickness bladder wall cystotomy. STUDY DESIGN: Data about all UTV-CS between January 2013 and December 2017 were retrieved searching the diagnosis of bladder injury and bladder repair during caesarean section (CS) in our comprehensive computerized labor and delivery database and register. CS with bladder wall injury not classified as UTV-CS were excluded. Data analysis included maternal history, demographics and obstetric parameters, details regarding CSs, bladder injury location and extension, and short- and long-term maternal outcomes. RESULTS: Among 28,822 deliveries, 7,616 (26.42%) were CSs. Three cases of UTV-CS were identified with comprehensive incidence of 0.039%. We provided details of the reported cases and described bladder repair procedure. CONCLUSION(S): This is the first study that assessed the incidence of UTV-CS. UTV-CS risk factors are consistent with factors related to milder bladder injuries. The risk of bladder injury during CS should be always considered, despite the low incidence of this complication. Prompt diagnosis and surgical repair seem to allow avoiding severe complications and recovery of a normal urological function even in UTV-CS.

Laparoscopic reversible occlusion of uterine arteries and cornuostomy for advanced interstitial pregnancy.

During laparoscopic enucleation of an interstitial pregnancy, adequate hemostatic control is of paramount importance due to the high vascularization of the uterine cornus. However, no consensus or guidance exists regarding the optimal hemostatic technique. We report laparoscopic reversible uterine arteries occlusion as hemostatic technique during laparoscopic enucleation by cornuostomy of an interstitial pregnancy at advanced gestational age (46 × 40 mm gestational sac). Preliminary identification of the uterine arteries and bilateral reversible occlusion by Hem-o-Lok clips allowed bleeding control during surgery. The laparoscopic procedure was performed without complications and with limited blood loss. The reported case reinforces the feasibility of this minimally invasive technique in interstitial pregnancy.

Mesenteric vascular and nerve sparing surgery in laparoscopic segmental intestinal resection for deep infiltrating endometriosis.

OBJECTIVE(S): To investigate Mesenteric vascular and nerve Sparing Surgery (MSS) as surgical laparoscopic technique to perform segmental intestinal resection for deep infiltrating endometriosis (DIE). STUDY DESIGN: Prospective cohort study between January 2013 and December 2016. Consecutive patients with suspected intestinal DIE underwent clinical and imaging evaluation to confirm intestinal involvement. Indications for radical surgery and surgical technique (intestinal resection versus shaving) were consistent with Abrão algorithm. Surgeons aimed to perform MSS in all the consecutive patients that required intestinal resection. MSS consists in mesenteric artery, branching arteries, and surrounding nerve fibers preservation by dissecting mesentery adherent to the intestinal wall. Data about history, preoperative and post-operative evaluation, surgery and complications were recorded. Symptoms were evaluated before and 30-60 days after surgery with numeric rating scale for pain. Constipation was evaluated with the Constipation Assessment Scale (CAS). Patients with diagnosis of irritable bowel syndrome, inflammatory bowel diseases, diverticulitis, and previous segmental intestinal resection were excluded. RESULTS: Sixty-two out of 75 (82.7%) consecutive women with intestinal endometriosis underwent laparoscopic segmental intestinal resection performed with MSS. Major complications that required repeated operation occurred in 4 cases (6.5%). Anastomotic leakage occurred in only 1 case (1.6%). Dysmenorrhea (p < .001; r = -0.86), dyspareunia (p < .001; r = -0.80), dyschezia (p < .001; r = -0.86) and dysuria (p < .001; r = -0.56) were significantly improved after surgery. After an average of 33.1 months from surgery, severe constipation was reported only by two patients (3.6%) (CAS: 13-16). The median time from surgery to intestinal function recovery (flatus or stool passage) was one day. Logistic regression analysis showed constipation related to the distance from anal verge and time since surgery. CONCLUSION(S): MSS in laparoscopic intestinal resection for DIE may be reproducible, safe and effective. MSS could be combined with pelvic nerve-sparing surgery as an effective approach to improve intestinal symptoms after radical surgery for DIE that requires segmental intestinal resection.

Primary hepatic pregnancy: report of a case treated with laparoscopic approach and review of the literature.

OBJECTIVE: To report a case of primary hepatic pregnancy complicated by acute hemoperitoneum that was treated with a laparoscopic approach. DESIGN: Case report and review of the literature. SETTING: Obstetrics and gynecology unit of a university hospital. PATIENT(S): A 37-year-old pregnant woman who presented with vaginal bleeding. INTERVENTION(S): Diagnosis by abdominal ultrasound and computed tomography. MAIN OUTCOME MEASURE(S): Patient recovery after minimally invasive laparoscopic surgery and monitoring. RESULT(S): A hepatic ectopic pregnancy complicated by hemoperitoneum was diagnosed. The hepatic pregnancy was surgically removed via laparoscopy through a retroperitoneal approach, and the patient's human chorionic gonadotropin level was subsequently monitored. The patient's postoperative course was uneventful, and the serum human chorionic gonadotropin level dropped to zero. CONCLUSION(S): Only 39 cases of hepatic pregnancy have been reported in the literature, making it an exceptional category among abdominal pregnancies. Hepatic localization should be ruled out in cases of unknown pregnancy location. Abdominal ultrasound has a key role detecting hepatic localization and excluding other abdominal implantation sites. Laparoscopic surgery represents a feasible approach for the treatment of first trimester hepatic pregnancies.

Influence of Ulipristal Acetate Therapy on Uterine Fibroid-Related Symptoms and on Uterine and Fibroid Volumes and Vascularity Indices Assessed by Ultrasound.

OBJECTIVES: To investigate the modifications of uterine and fibroid volume, to study Doppler changes in uterine arteries and fibroid-supplying vessels, and to assess possible symptomatic relief after 3 months of treatment with ulipristal acetate. METHODS: Forty-two premenopausal women with symptomatic fibroids were included in the study. They were evaluated clinically for the symptoms reported and underwent ultrasound examinations before starting treatment and after 3 months of therapy with ulipristal acetate. Transvaginal scanning was performed by the same sonographer, who measured the uterine volume and uterine artery pulsatility index and resistive index. Considering that some patients had more than 1 fibroid, the vascularization (supplying vessel pulsatility and resistive indices), locations, and sizes of a total of 73 fibroids were also recorded. RESULTS: After 3 months of ulipristal acetate, patients had a significant improvement of all symptoms (P < .05). The percentage of uterine volume reduction was 14% (P = .03), with fibroid volume reduction of 32.8% (P = .01). Uterine artery vascular indices decreased after treatment, but their reduction did not reach significant results, whereas all fibroid vascular indices decreased significantly after 3 months of ulipristal acetate (P < .05). When the fibroids were divided according to their localization, all had significant volume reduction after therapy, but type 5 had the highest decrease (42%) compared to other fibroid types (P = .03). CONCLUSIONS: Fibroid treatment with ulipristal acetate resulted in a significant improvement of fibroid-related symptoms; moreover, it proved to be effective in decreasing both uterine and fibroid volumes and fibroid vascularization. Type 5 fibroids seem to have the most major response to treatment.

Preoperative assessment of intestinal endometriosis: A comparison of transvaginal sonography with water-contrast in the rectum, transrectal sonography, and barium enema.

To evaluate the accuracy of Transrectal Sonography (TRS) and a new technique, Transvaginal Sonography with Water-Contrast in the Rectum (RWC-TVS), in the diagnosis of rectosigmoid endometriosis, and the accuracy of Barium Enema (BE) and RWC-TVS in the detection of intestinal stenosis due to endometriosis. In a prospective study, we compared the findings of TRS and RWC-TVS performed before surgery with the operative and pathologic findings in 61 consecutive patients who underwent laparoscopy or laparotomy for suspected rectosigmoid endometriosis. The accuracy of BE and RWC-TVS in the detection of intestinal stenosis was evaluated comparing the radiologic and ultrasonographic results with the macroscopic findings at surgery and pathology. RWC-TVS diagnosed rectosigmoid endometriosis with the same accuracy of TRS and was equally efficient as BE in the detection of a significant intestinal lumen stenosis. For the diagnosis of rectosigmoid endometriosis the sensitivity, specificity, positive and negative predictive values of TRS and RWC-TVS were 88.2% and 96%, 80%, and 90%, 95.7%, and 98%, and 57.1% and 81.8%, respectively. For the detection of intestinal stenosis the sensitivity, specificity, positive and negative predictive values of BE and RWC-TVS were 93.7% and 87.5%, 94.2% and 91.4%, 88.2% and 82.3%, and 97% and 94.1%, respectively. RWC-TVS is a new, simple technique for a single-step and accurate preoperative assessment of rectosigmoid endometriosis.

Effects of female sex hormones and contraceptive pill on the diagnostic work-up for primary aldosteronism.

OBJECTIVES: Due to the widespread use of the aldosterone to renin ratio (ARR), primary aldosteronism is currently recognized as a frequent cause of secondary hypertension. After a positive screening, primary aldosteronism diagnosis needs confirmation by an inhibitory test such as intravenous saline load (ivSLT). The aim of the present study was to investigate the role of female hormones in primary aldosteronism diagnosis, by evaluating possible differences by sex on ARR screening, on the rate of ivSLT response and analyzing the influence of free and oral contraceptive-induced menstrual cycle on ARR. METHODS: We examined ARR in 103 healthy normotensive volunteers, 81 hypertensive patients who underwent ivSLT, 33 healthy women during free menstrual cycle and after oral contraceptive therapy. RESULTS: A significantly higher proportion of normotensive women than men had an elevated ARR (13.6 versus 2.3%, P < 0.05). In 44 out of 81 hypertensive patients, diagnosis of primary aldosteronism was confirmed by ivSLT. Patients with positive and negative ivSLT differed only for sex distribution: 85.2% of men had the primary aldosteronism diagnosis confirmed, compared with 38.9% of women. In healthy women, renin and aldosterone concentrations increased from the follicular to luteal phase of menstrual period, with unchanged ARR. By contrast, renin nearly halved, aldosterone slightly decreased and ARR doubled after oral contraceptive therapy. CONCLUSION: ARR screening fails to predict positive ivSLT in most (60.2%) hypertensive women as compared with 14.8% of hypertensive men. ARR is more often increased in normotensive women than men. Oral contraceptive may affect ARR contributing to the diagnostic inaccuracy in women.
