4DryField vs. hyalobarrier gel for preventing the recurrence of intrauterine adhesions - a pilot study

INTRODUCTION

This was a single-center pilot study that sought to describe an innovative use of 4DryField® PH (premix) for preventing the recurrence of intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis in patients with Asherman's syndrome (AS).

MATERIAL AND METHODS

Twenty-three patients with AS were enrolled and 20 were randomized (1:1 ratio) to intrauterine application of 4DryField® PH (n = 10) or Hyalobarrier® gel (n = 10) in a single-blind manner. We evaluated IUAs (American Fertility Society [AFS] score) during initial hysteroscopy and second-look hysteroscopy one month later. Patients completed a follow-up symptoms questionnaire three and reproductive outcomes questionnaire six months later.

RESULTS

The demographic and clinical characteristics, as well as severity of IUAs, were comparable in both groups. The mean initial AFS score was 9 and 8.5 in the 4DryField® PH and Hyalobarrier® gel groups, respectively (p = .476). There were no between-group differences in AFS progress (5.9 vs. 5.6, p = .675), need for secondary adhesiolysis (7 vs. 7 patients, p = 1), and the follow-up outcomes.

CONCLUSION

4DryField® PH could be a promising antiadhesive agent for preventing the recurrence of IUAs, showing similar effectiveness and safety to Hyalobarrier® gel. Our findings warrant prospective validation in a larger clinical trial.

The fertility sparing therapy in ectopic pregnancy

OBJECTIVE

A review of current knowledge on the possibilities of fertility sparing therapy in case of ectopic pregnancy.

METHODS AND RESULTS

Ectopic pregnancy is defined as implantation of an embryo outside the endometrial cavity, most often in the fallopian tube. This dia-gnosis is very common among young women. Ectopic pregnancies can be treated using the following three approaches, which can be combined: expectantly, pharmacologically or surgically. Fertility-sparing salpingostomy may be performed during surgical treatment. Medical (pharmacological) treatment consists in the application of methotrexate with a success rate of 75-96%, depending on the initial level of the free beta subunit of human chorionic gonadotropin (b-hCG). This is a safe treatment with minimal side effects. There is no standardization of the blood b-hCG level limits or of the size of the ectopic pregnancy mass for choosing expectant, surgical or medical treatment. A considerable increase in the rate of Cesarean sections over the last decades has led to an increase in the occurrence of the implantation of the gestational sac in the hysterotomy scar. There are several options to address this dia-gnosis, but none is clearly preferred. This issue is also discussed in the article.

CONCLUSION

The goal of ectopic pregnancy treatment is to choose a safe and effective therapy with a low incidence of side effects and maintaining the maximum fertility of women. Properly set indication criteria are most important when choosing the right option.

Comparison of complications in very obese women undergoing hysterectomy - Abdominal vs laparoscopic approach with short- and long-term follow-up

BACKGROUND

Surgical treatment of obese female patients represents a real challenge. Over the last decade, minimally invasive techniques for hysterectomy have emerged. These approaches reduce the invasiveness of standard surgical procedures while maintaining efficacy and feasibility.

OBJECTIVE

To evaluate the rates of perioperative, early, mid-term and late postoperative complications in very obese [body mass index (BMI) ≥ 35 and < 40 kg/m²] and severely obese (BMI ≥ 40 kg/m²) women who underwent total (non-radical) hysterectomy.

DESIGN

A prospective comparative multi-centre non-randomized study.

METHODS

In total, 328 consecutive total (non-radical) hysterectomies were performed at seven teaching gynaecological centres. Of these, 153 (46.6%) were performed using an open laparotomy (LT) approach and 175 (53.4%) were performed laparoscopically (LS). All data were collected by medical specialists at the pre-operative examination prior to surgery, during surgery and three times postoperatively (during hospital stay, at 6-week follow-up and 6 months following surgery). Another analysis considered a total of 206 women who underwent laparoscopic hysterectomy. The subjects were divided according to BMI into 120 very obese women (BMI ≥ 35 and < 40 kg/m²) and 86 severely obese women (BMI ≥ 40 kg/m²).

RESULTS

The total number of composite perioperative complications was significantly lower in the LS group (p = 0.006). Composite complications occurred significantly more often in patients in the LT group compared with the LS group in the early (p < 0.001) and mid-term (p < 0.001) postoperative periods. In the late postoperative period, the total number of composite postoperative complications did not differ significantly between the groups (p < 0.396). Among 206 patients who underwent laparoscopic hysterectomy, the number of complications was generally low; the rates of composite perioperative (p = 0.393), early (p = 0.642), mid-term (p = 0.738) and late (p = 1) postoperative complications were generally low; and frequency did not differ significantly with BMI.

CONCLUSION

The LS approach does not increase intra-operative morbidity associated with surgery, and has significantly better outcomes in terms of the postoperative complication rate.

Uterus sparing surgery in adenomyosis and its impact on reproductive outcomes

OBJECTIVE

The purpose of this study was to evaluate the appropriate surgical treatment of adenomyosis and its impact on reproductive outcomes.

CONCLUSION

Patients with adenomyosis and fibroids may show a lower pregnancy rate and higher miscarriage rate than healthy individuals. However, there is no standard protocol for their optimal treatment, particularly in pregnancy-seeking or infertile women. Myomectomy is generally a commonly performed procedure that preserves fertility. On the other hand, the role of surgery in extensive uterine adenomyosis remains controversial, because adenomyosis often involves the whole uterus diffusely. It is almost impossible to remove all pathological tissue from the surrounding myometrium. Therefore, this procedure is called debulking/cytoreductive surgery. However, adenomyomectomy has also become a more common type of surgical intervention in recent years.

Are we better off using multiple endometriosis classifications in imaging and surgery than settle for one universal less than perfect protocol? Review of staging systems in ultrasound, magnetic resonance and surgery

There are multiple classifications in imaging and surgery of endometriosis and in this article, we offer a review of the main evaluation systems. The International Deep Endometriosis Analysis group consensus is the leading document for ultrasound assessment, while magnetic resonance imaging is guided by the European Society for Urogenital Radiology recommendations on technical protocol. In surgery, the revised American Society for Reproductive Medicine classification is the oldest system, ideally combined with newer classifications, such as Enzian or Endometriosis Fertility Index. Recently, The World Endometriosis Research Foundation Endometriosis Phenome and Biobanking Harmonisation Project introduced detailed proforma for clinical and intraoperative findings. There is still no universal consensus, so the initial emphasis should be on the uniform reporting of the disease extent until research clarifies more the correlations between extent, symptoms and progression in order to develop a reliable staging system.Impact StatementWhat is already known on this subject? There have been several reviews of surgical classifications, comparing their scope and practical use, while in the imaging the attempts for literature review has been scarce.What do the results of this study add? This is the first up to date review offering detailed analysis of the main classification systems across the three main areas involved in endometriosis care - ultrasound, MRI and surgery. The mutual awareness of the radiological classifications for surgeons and vice versa is crucial in an efficient multidisciplinary communication and patient care. On these comparisons we were able to demonstrate the lack of consensus in description of the extent of the disease and even further lack of prognostic features (with the exemption of one surgical system).What are the implications of these findings for clinical practice and/or further research? Future attempts of scientific societies should focus on defining uniform nomenclature for extent description. In the second step the staging classification should encompass prognostic value (risk of disease and symptoms recurrence).

Hysteroscopic management of endometrial polyps and submucous leiomyomas in women using a levonorgestrel-releasing intrauterine system

INTRODUCTION

This study was designed to evaluate the feasibility and effectiveness of hysteroscopy in the management of symptoms related to endometrial polyps and submucous leiomyomas in women using a levonorgestrel-releasing intrauterine system (LNG-IUS).

MATERIAL AND METHODS

Twenty-three LNG-IUS users presenting with endometrial polyps and/or submucous leiomyomas and irregular uterine bleeding were recruited for hysteroscopic examination and surgery. Intrauterine pathology was investigated and treated by hysteroscopic resection with the LNG-IUS in situ, and the effect of the procedure on symptoms was evaluated after three to six months.

RESULTS

Intrauterine pathology was successfully resected by hysteroscopy in 23 (100.0%) out of 23 cases. Following hysteroscopy, 18 (78.3%) women reported amenorrhea, one (4.3%) regular spotting, three (13.0%) irregular spotting and one (4.3%) patient resumed normal menstrual cycle. We conclude that 19 (82.6%) patients were postoperatively asymptomatic. All procedures were uncomplicated and 4 (17.4%) were carried out without general anesthesia as office procedures.

CONCLUSION

Endometrial polyps and submucous leiomyomas can develop in LNG-IUS users, and this can cause irregular uterine bleeding. Hysteroscopic resection of these pathologies is a feasible method in the clinical management of symptoms.

Diagnostic Accuracy of Ultrasound and MRI in the Mapping of Deep Pelvic Endometriosis Using the International Deep Endometriosis Analysis (IDEA) Consensus

OBJECTIVES

The primary aim was to investigate the diagnostic accuracy of transvaginal ultrasound (TVS) and magnetic resonance imaging (MRI) in the mapping of deep pelvic endometriosis (DE) in a diseased population. The secondary aim was to offer first insights into the clinical applicability of the new International Deep Endometriosis Analysis group (IDEA) consensus for sonographic evaluation, which was also adapted for MRI and surgical reporting in this study.

METHODS

The study was a prospective observational cohort study. In this study, consecutive women planned for surgical treatment for DE underwent preoperative mapping of pelvic disease using TVS and MRI (index tests). The results were compared against the intraoperative findings with histopathological confirmation (reference standard). In case of disagreement between intraoperative and pathology findings, the latter was prioritised. Index tests and surgical findings were reported using a standardised protocol based on the IDEA consensus.

RESULTS

The study ran from 07/2016 to 02/2018. One-hundred and eleven women were approached, but 60 declined participation. Out of the 51 initially recruited women, two were excluded due to the missing reference standard. Both methods (TVS and MRI) had the same sensitivity and specificity in the detection of DE in the upper rectum (UpR) and rectosigmoid (RS) (UpR TVS and MRI sensitivity and specificity 100%; RS TVS and MRI sensitivity 94%; TVS and MRI specificity 84%). In the assessment of DE in the bladder (Bl), uterosacral ligaments (USL), vagina (V), rectovaginal septum (RVS), and overall pelvis (P), TVS had marginally higher specificity but lower sensitivity than MRI (Bl TVS sensitivity 89%, specificity 100%, MRI sensitivity 100%, specificity 95%; USL TVS sensitivity 74%, specificity 67%, MRI sensitivity 94%, specificity 60%; V TVS sensitivity 55%, specificity 100%, MRI sensitivity 73%, specificity 95%; RVS TVS sensitivity 67%, specificity 100%, MRI sensitivity 83%, specificity 93%; P TVS sensitivity 78%, specificity 97%, MRI sensitivity 91%, specificity 91%). No significant differences in diagnostic accuracy between TVS and MRI were observed except USL assessment (p=0.04) where MRI was significantly better and pouch of Douglas obliteration (p=0.04) where MRI was significantly better and pouch of Douglas obliteration (κ) = 0.727 [p=0.04) where MRI was significantly better and pouch of Douglas obliteration (κ) = 0.727 [p=0.04) where MRI was significantly better and pouch of Douglas obliteration (p=0.04) where MRI was significantly better and pouch of Douglas obliteration (.

CONCLUSION

We found that both imaging techniques had overall good agreement with the reference standard in the detection of deep pelvic endometriosis. This is the first study to date involving the IDEA consensus for ultrasound, its modified version for MRI, and intraoperative reporting of deep pelvic endometriosis in clinical practice.

Diagnostic pitfalls in ovarian androgen-secreting (Leydig cell) tumours: case series

Leydig cell tumours of the ovary are rare and represent a diagnostic challenge not only due to their sporadic incidence but also due to the seemingly normal imaging. We present three cases of pre- and postmenopausal women who were presented with severe clinical signs of hyperandogenism where modern imaging modalities (including computed tomography (CT), magnetic resonance imaging (MRI) and positron-emission tomography combined with computed tomography (PET-CT)) failed to identify the tumour. Two patients underwent non-expert ultrasound, CT and MRI examination with uniform conclusion that ovaries are of normal appearance. One of the two patients even had a PET-CT performed, which was inconclusive. Our case reports show the importance of examination by specialists with established skills in gynaecologic ultrasonography in the diagnosis of the Leydig cell tumours. The most useful diagnostic tool seems to be the combination of age (postmenopause), symptoms (onset of hirsutism and virilisation), high total testosterone plasma values and expert sonography. On ultrasound, these tumours are unilateral, usually small, solid intraovarian nodules of a slightly increased echogenicity in contrast to the surrounding ovarian tissue, delineated by abundant perfusion with an enhanced vascularity. The appropriate setting of the sensitive colour Doppler is crucial for the detection of intraovarian Leydig cell tumour. Impact statement What is already known on this subject? A diagnosis of Leydig cell tumours is based on ultrasound performed by a trained examiner or by MRI. CT or PET/CT are not among the primary methods of choice. According to the results of imaging investigations surgical treatment is planned. Because these tumours are usually benign and have a good prognosis the unilateral salpingo-oophorectomy is a standard procedure. What do the results of this study add? Our case series show how difficult it can be to establish the diagnosis of Leydig cell tumours by imaging, including transvaginal ultrasound, the most frequently recommended diagnostic tool. We demonstrate in three cases how easily a small hyperechogenic tumour can be overseen or interchanged for a different gynaecological pathology if transvaginal scan is not performed by an experienced examiner trained in sonographic features of gynaecologic neoplasms. What are the implications of these findings for clinical practice and/or further research? This case series demonstrate how important it is to see the patient in the whole complexity with their medical history, proper clinical symptoms evaluation, laboratory test and not to rely solely just on sophisticated high-end investigations, such as the PET-CT, a CT and an MRI. It also emphasises the importance of specialists with established skills in gynaecologic ultrasonography. Further effort should be made to define the resources for the appropriate training of such sonographers.

Malignant endometrial polyp in woman with the levonorgestrel intrauterine system - a case report

The levonorgestrel-releasing intrauterine system (LNG-IUS) is widely used and recommended as a reliable contraceptive. It also acts by opposing the effects of estrogen on the endometrium, thereby preventing development of endometrial hyperplasia and its possible malignant transformation. This case describes a 52-year-old multiparous amenorrhoeic patient who was seen in the gynecology outpatient department for a routine control 46 months after the insertion LNG-IUS as contraception. Hysteroscopy with a target biopsy following suspicious ultrasound scan confirmed well-differentiated endometrioid adenocarcinoma. Ultrasound scan prior to inserting LNG-IUS revealed normal 5 mm thin endometrium with the sharp edges. Uterine bleeding before the LNG-IUS insertion was regular and not excessive and the woman has remained amenorrhoeic after the LNG-IUS insertion. We present a case of the growth of a polyp-shaped endometrial carcinoma in a LNG-IUS asymptomatic user.

Endometriosis in pregnancy - diagnostics and management

OBJECTIVE

Endometriosis in pregnancy predominantly tends to regress or to stay stable but small part of endometriomas and nodules of deep infiltrating endometriosis may undergo the process of decidualization. Therefore, the foci of endometriosis enlarge their volume and change their structure due to cellular hypertrophy and stromal edema associated with higher vascularization caused by the hormonal changes in pregnant women. Consequently, these totally benign lesions may resemble malignant tumors in ultrasound examination.

DESIGN

Review article.

SETTING

Department of Obstetrics and Gynecology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Prague.

METHODS

A literature review of published data on decidualization of endometriosis.

RESULTS

Majority of decidualized ovarian endometriomas is asymptomatic so it is mostly accidentally found during the routine ultrasound check-ups within the frame of perinatologic screening. The rounded, smooth, highly vascularized solid papillary projections in internal wall of endometroid cysts are the most specific characteristics of decidualization. If ultrasound simple rules are not applicable or show probable malignancy, the pregnant patient should be referred to a tertiary center for expert ultrasound assessment. Magnetic resonance is indicated in cases of uncertain ultrasound findings, because it can clarify the diagnostics due to its high accuracy in detection of products of blood degradation and ability of diffusion-weighted imaging to recognize lower tissue cellularity of benign decidualized endometriomas in comparison to malignant ovarian tumors.

CONCLUSION

If the imaging methods confirm supposed decidualized endometriosis, watch and wait management based on regular ultrasound examinations during the whole pregnancy and after childbed is recommended. The regression of the tumor size and disappearance of the solid portions within endometriomas is expected after delivery. Decidualized endometriosis is rarely a source of gestational or obstetrical complications demanding acute surgical intervention. Elective surgical procedures in pregnant women are indicated only if expert ultrasound or magnetic resonance imaging assess the masses as border-line or invasive tumors (carcinomas) and in cases of suspicious changes of the originally presumed benign cysts during the surveillance.

Diagnosis of endometriosis 3rd part - Ultrasound diagnosis of deep endometriosis

OBJECTIVE

To summarise the current knowledge and trends in the diagnosis of deep endometriosis.

DESIGN

Review article.

SETTING

Centre for diagnostics and treatment of endometriosis and Gynecologic Oncology Centre, Department of Obstetrics and Gynaecology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Department of Gynaecology and Obstetrics, Burton Hospitals NHS, United Kingdom.

METHODS

Literature review.

RESULTS

Deep endometriosis (DE) in the pelvis is divided into lesions in the anterior and posterior compartment. In the anterior compartment DE infiltrates bladder and ureters, while in the posterior compartment it is mostly uterosacral ligaments, rectum, rectosigmoid and sigmoid colon and rarely rectovaginal septum and posterior fornix. Extrapelvic endometriosis is a rare disease typically located in the proximal bowel segments (jejunum/ileum/appendix), abdominal wall including umbilicus, scars after spontaneus delivery and/or after cesarian section, lungs and diaphragm.

CONCLUSION

Ultrasound diagnosis of pelvic DE has a high accuracy in the hands of an experienced sonographer. Extrapelvic endometriosis is sporadic and imaging of choice depends on the location, such as use of magnetic resonance in retroperitoneal disease (sciatic nerve), computed tomography or endoscopy in thoracic lesions.

Diagnosis of endometriosis 2nd part - Ultrasound diagnosis of endometriosis (adenomyosis, endometriomas, adhesions) in the community

OBJECTIVE

To summarise the current knowledge and trends in the basic ultrasound diagnosis of adenomyosis, endometroid cysts and pelvic adhesions.

DESIGN

Review article.

SETTING

Centre for diagnostics and treatment of endometriosis and Gynecologic Oncology Centre, Department of Obstetrics and Gynaecology, First Faculty of Medicine, Charles University and General University Hospital in Prague, Department of Gynaecology and Obstetrics, Burton Hospitals NHS, United Kingdom.

METHODS

Literature review.

RESULTS

Endometriosis is a relatively common disease, which often escapes timely diagnosis, although sonographic features of adenomyosis, endometriomas and pelvic adhesions can be easily assessed on the basic ultrasound examination. Endometriomas are ovarian cysts in a premenopausal patient with ground glass echogenicity of the cyst fluid, one to four locules and no papilary projections with detectable blood flow. Adenomyosis is characterised by an asymmetrical thickening of the myometrium due to an ill-defined myometrial lesion with fan-shaped shadowing, non-uniform echogenicity with myometrial cysts, hyperechogenic islands, hyperechogenic subendometrial lines and buds with an irregular or interrupted junctional zone, and translesional vascularity containing vessels crossing the leasion perpendicular to the endometrium. Pelvic adhesions can be detected using dynamic aspect of ultrasound examination demonstrating negative sliding sign of the uterus and/or ovaries against surrounding tissue planes and site-specific tenderness. Distorted pelvic anatomy (the presence of uterine &#8218;question mark sign and/or &#8218;kissing ovaries) is another sign of adhesions.

CONCLUSION

First step in basic transvaginal ultrasound is visualisation of the uterus and ovaries, assessment of their mobility and tenderness during examination. Knowledge of the characteristic ultrasound features of adenomyosis, endometriomas and adhesions enables timely diagnosis of endometriosis by the community gynecologist and prompt referral to the endometriosis centre.

[Hirsutism]

OBJECTIVE

Overview of excessive hair growth in women, hirsutism. Although women with hirsutism typically present because of cosmetic concerns, the majority also have an underlying endocrine disorder.

DESIGN

Review article.

SETTING

Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Faculty of Medicine of Charles Universtity, Prague.

MATERIAL AND METHODS

Hirsutism is a clinical diagnosis defined by the presence of excess terminal hair growth (dark, coarse hairs) in androgen-sensitive areas. It affects between five and ten percent of women of reproductive age. It may be the initial, and possibly only, sign of an underlying androgen disorder.

CONCLUSIONS

The most common cause of hirsutism is polycystic ovary syndrome (PCOS). In some cases, hirsutism is mild and requires only reassurance and local (nonsystemic) therapy, while in others it causes significant psychological distress and requires more extensive therapy. In case of rapid progressive hair growth should be first exclude androgen-secerning tumour (ovarian, adrenal) as the most serious condition.

[Management of Medical Termination of Pregnancy (MToP) up until the 7th week of gestation in the Czech Republic]

OBJECTIVE

In the Czech Republic (CR), it is possible, to carry out Medical Termination of Pregnancy (MToP) in the 1st trimester since June 2014, in case a woman submits a written request for it and in case the ultrasound examination confirms an intrauterine singleton prosperous pregnancy, between day 42 and 49 of gestation, crown-rump length (CRL) of the embryo 2-9 mm. The aim of the study is to analyze the management of MToP up until the 7th week of gestation in five centres in the CR.

DESIGN

Multicenter cohort (prospective) study.

SETTING

Department of Obstetrics and Gynecology, Palacky University Olomouc, Faculty of Medicine and Dentistry, University Hospital Olomouc; The Institute for the Care of Mother and Child, Charles University in Prague, Third faculty of Medicine; Department of Gynecology and Obstetrics, Charles University in Prague, First faculty of Medicine, General University Hospital in Prague; Department of Gynecology and Obstetrics, Charles University in Prague, First faculty of Medicine, Hospital Na Bulovce, Prague; Department of Gynecology and Obstetrics, Masaryk University, Faculty of Medicine, University Hospital Brno.

METHODS

In 2014-2016, a total of 1820 pregnant women requested MToP. The diagnosis of an intrauterine singleton prosperous pregnancy was set by transvaginal ultrasound, CRL 2-9 mm. MToP was carried out by combination of mifepristone (600 mg orally) and misoprostol (400 mcg orally) within 48 hours. MToP follow up (exclusion of ongoing pregnancy) after 2-3 weeks was carried out by transvaginal ultrasound as well.

RESULTS

In 11.0% of women (201/1820) who requested MToP, CRL > 9 mm, unprosperous, multiple or ectopic pregnancy was diagnosed. In the remaining 1619 women MToP was carried out, but in 221 cases (13.7%) at least one additional pre-first visit was needed before the diagnosis of intrauterine singleton prosperous pregnancy CRL 2-9 mm could be established, in 19 cases (1.2%) two pre-first visits and in 5 cases (0.3%) even three. Gestational age was 42-49 days (average 47.1, median 47), the women were 14-47 years of age (average 30.7, median 30). In 20.8% of women (336/1619) MToP follow up was missed and of the remaining 1283 women, ongoing pregnancy (MToP failure) was diagnosed in 1.6% (24/1283), incomplete abortion in 6.5% (83/1283) and complete abortion in 91.9% (1179/1283). A subsequent surgical intervention was carried out in 7.1 % of women (91/1283).

CONCLUSION

A medical facility performing MToP in the 1st trimester should develop its own methodology in accordance with the legislation in force, Summaries of Product Characteristics, and recommendations of professional associations. The methodology should also include a method of evaluation of the result and management. The subsequent surgical intervention should only be performed in indicated cases. The main goal of MToP follow up is to exclude ongoing pregnancy (MToP failure), and the patient should be informed in detail about the risks involved and possibilities of their solution, it is necessary to obtain an informed consent.

[Endometriosis and quality of life]

OBJECTIVE

This article aims to provide a comprehensive overview of the possibilities of evaluating the impact of symptoms of endometriosis on quality of life of affected women and to overview the effect of treatment modalities in improving of the quality of their life.

DESIGN

Review article.

SETTING

Department of Obstetrics and Gynecology, First Faculty of Medicine, Charles University and General University Hospital in Prague.

METHODS

Review of results of published studies evaluating quality of life in patients with endometriosis.

CONCLUSION

Symptoms of endometriosis decrease the quality of life of affected women, which has significant impact on society. Since the extent of endometriosis does not correlate with subjective complaints, it is suitable to evaluate the quality of life of patients in addition to assessment of the extent and classification of the disease (according to internationally accepted classification). The quality of life could be measured and compared by structured interviews or by validated questionnaires. Pharmacological as well as surgical treatment significantly improve quality of life of patients with endometriosis. Routine use of validated questionnaires of quality of life in patients with endometriosis might improve the assessment of severity of the disease and evaluation of effectiveness of the treatment in the future.

The utility of fasting plasma glucose to identify impaired glucose metabolism in women with polycystic ovary syndrome

We evaluated the utility of impaired fasting plasma glucose as defined by ADA to identify women with polycystic ovary syndrome (PCOS) affected by impaired glucose metabolism (i.e. impaired fasting glucose, impaired glucose tolerance and diabetes mellitus). In 330 women with PCOS, according to ESHRE criteria, an oral glucose tolerance test was done. Impaired fasting glucose was present in 36 women (12%), impaired glucose tolerance in 29 women (8.8%) and diabetes mellitus in 10 women (3%), 4 of them have fasting glucose higher than 7 mmol/l. The combination of impaired fasting glucose and impaired glucose tolerance was seen in 5 women (1.5%). The sensitivity of impaired fasting glucose for the detection of impaired glucose tolerance was 24% and specificity 91.8%. When fasting glucose above 5.6 mmol/l was used as the screening criterion, 28/35 subjects (80%) would have been missed. We conclude that fasting plasma glucose is not sufficiently sensitive for the detection of impaired glucose tolerance and diabetes mellitus type 2 in women with PCOS.

Is polycystic ovary syndrome, a state of relative estrogen excess, a real risk factor for estrogen-dependant malignancies?

Polycystic ovary syndrome (PCOS) is a common endocrinopathy affecting women of fertile age. It is associated with several risk factors and long-term health consequences. Chronic anovulation combined with relative estrogen excess and consequent prolonged stimulatory effect on the endometrium can lead to the pathogenesis of hormonal dependant carcinoma. PCOS is thus traditionally reported to be associated with increased risk of endometrial, as well as breast and ovarian cancers. This article provides a critical literature review of the relationship between PCOS and the incidence of estrogen-dependant gynecological tumours, and it then discusses whether the commonly cited risk factor association can be substantiated by high quality studies which comply with the requirements of "evidence-based medicine."

[Laparoscopic lymph-node dissection in gynecological surgery]

OBJECTIVE

To analyze our experience with transperitoneal laparoscopic dissection of lymphatic nodes in women with gynecologic malignancies.

STUDY DESIGN

Retrospective clinical study.

SETTING

Center of gynecologic endoscopy and minimally invasive surgery; Department of Obstetrics and Gynecology, General Faculty Hospital and 1st Medical Faculty in Prague.

METHODS

Analysis of data from our laparoscopic procedures in the years 2006-2011. The following procedures have been included: systematic pelvic lymphadenectomy (PLN), paraaortic lymphadenectomy (PALN), pelvic sentinel node excision, focused dissection of bulky lymphatic nodes from pelvis or paraaortic area.

RESULTS

We performed 177 primarily laparoscopic procedures pointed at dissection of pelvic and/or paraaortic lymph-nodes. The mean operating time and the mean number of lymph-nodes was 82 minutes and 26.5 nodes in patients with PLN, and 75 minutes and 12.5 nodes in patients with PALN. The overall rate of laparo-conversions was 4.5%; the incidence of major complications was 6.8% and of serious bleeding 5.6%. Laparoscopic lymphadenectomy could not be performed or completed in 2.3% of cases. Complications were more frequently associated with PALN than with PLN.

SUMMARY

Laparoscopic approach to PLN and PALN is feasible in vast majority of patients. It provides adequate earnings of the lymphatic nodes, tolerable operative time, and relatively low complication rate. The highly experienced operation team for especially high infrarenal PALN is necessary.

[Endometriosis]

OBJECTIVE

To summarize current knowledge of pathogenesis, diagnostics and treatment of endometriosis.

DESIGN

Review article.

SETTING

Centre for diagnostics and treatment of endometriosis, Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Faculty of Medicine of Charles University, Prague.

METHODS AND RESULTS

Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, which induces a chronic, inflammatory reaction. The condition is predominantly found in women of reproductive age, from all ethnic and social groups. The associated symptoms - pain, infertility - can impact on general physical, mental and social well being. Treatment must be individualised, taking the clinical problem in its entirety into account, including the impact of the disease and the effect of its treatment on quality of life. Pain symptoms may persist despite seemingly adequate medical and/or surgical treatment of the disease. In such circumstances, a multi-disciplinary approach involving a pain clinic and counselling should be considered early in the treatment plan.

CONCLUSION

Endometriosis is a medical condition with high recurrence rate and especially those patients with deep infiltrating endometriosis should be centralized to the centres experienced in diagnostics, complicated surgical treatment and providing multi-disciplinary approach with adequate postoperative care.

[Office hysteroscopy - management and results]

OBJECTIVE

Sum up the knowledge about office hysteroscopy.

TYPE OF STUDY

Review of literature and our own experience.

SETTING

Department of Gynaecology and Obstetrics, First Faculty of Medicine, Charles University Prague and General Teaching Hospital Prague.

METHODS

Data from scientific literature and 10 years of our own experience with office hysteroscopy.

CONCLUSIONS

Hysteroscopy provides optical evaluation of uterine cavity. Most of the benign intrauterine organics pathologies could be managed in a outpatient setting with a vaginoscopic approach without any anaesthesia and analgesia. Using that approach we can recommend to perform endometrial target biopsy, resection of endometrial polyps up to 1.5 cm and pedunculated submucous myomas up to 1 cm as well as resection of filmy intrauterine adhesions. Method is comfortable for well managed patients and practically complication-free.

[A recommended approach to evaluate cardiovascular risk and to prevent cardiovascular diseases and type 2 diabetes mellitus in women with polycystic ovary syndrome]

Polycystic ovary syndrome is one of the most common endocrinopathy in women of fertile age. It is commnoly accompanied by an increased occurence of cardiovascular risk factors. This association led to a consensus statement of Androgen Excess Society for screening of cardiovascular risk factors. We present the recommendations of Czech Endocrine and Czech Diabetological Societies for the screening and primary prevention of cardiovascular diseases and diabetes mellitus.

High-risk human papillomavirus DNA in paraaortic lymph nodes in advanced stages of cervical carcinoma

BACKGROUND

Paraaortic lymph nodes represent the second level in the lymphatic spread of cervical cancer. Recent studies have confirmed the association of HPV DNA in pelvic lymph nodes in early-stage disease with metastatic involvement and a less favourable prognosis.

OBJECTIVE

The aim of our study was to detect 13 high-risk genotypes of HPV in paraaortic nodes harvested from patients with FIGO IB2-IIIB tumours and correlate findings with histopathology.

STUDY DESIGN

The study involved patients with advanced cervical cancer who had undergone low paraaortic lymphadenectomy. The cytobrush technique was used for perioperative sample collection from the tumour and fresh lymphatic tissue. Patients with non-HPV related cancers were used as a control group.

RESULTS

The study involved 24 cervical cancer patients. High-risk HPV DNA was found in the primary tumour of all cases and in PALN in 16 (67%) cases. The most frequent genotype was HPV 16, both in the tumour and in the paraaortic lymph nodes (83% and 54%, respectively). Metastatic involvement of paraaortic lymph nodes was identified in 8 cases (33%), which all were also HPV DNA positive. No HPV DNA was detected in PALN in any of 22 control group cases.

CONCLUSIONS

Using the cytobrush technique, the presence of at least one HR HPV genotype in the primary tumour was identified in all the patients. The metastatically involved paraaortic lymph nodes always contained the DNA of at least one HPV genotype present in the primary tumour. Determination of clinical significance of HR HPV DNA presence in histologically negative lymph nodes requires further follow-up of the cohort.

Comparison of corticoid substitution versus combined oral contraception administration in the treatment of non-classic adrenal hyperplasia: a prospective study

OBJECTIVE

The clinical symptoms of non-classic adrenal hyperplasia (NCAH) are the same as those in patients with polycystic ovary syndrome (PCOS). The aim of our study was to compare conventional corticoid treatment of NCAH with the effect of combined oral contraception (COC) administration (used in treatment of PCOS) on clinical and laboratory parameters of NCAH.

DESIGN

A prospective clinical study, cross-over design.

MATERIAL AND METHODS

Since 1999 from 298 hyperandrogenic women, eight patients having 21-hydroxylase deficient NCAH have been identified. They were divided equally into two groups according to the order of application treatment modality (hydrocortison vs. COC). Effect of treatment of both modalities on clinical symptoms (hirsutism - FG score, acne, menstrual cycle) and laboratory parameters (testosterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulphate, sex hormone binding globulin (SHBG)) were evaluated.

RESULTS

We observed the decrease of plasma androgens in both groups, which did not differ significantly. Significant increase of SHBG (i.e. decrease of free androgens) was, however, documented in each period with COC administration. Not surprisingly, improvement of the most frequent clinical symptom of NCAH in our study group, oligomenorrhea, was also more apparent in COC. Hirsutism was only a minor problem in our group that did not allow to evaluate treatment effect of both the modalities

CONCLUSION

Our results indicate that ovarian suppression by COC administration can effectively suppress androgen production and improve the most frequent clinical symptom (irregular cycle) in patients with NCAH, so can be successfully used for the treatment at least under basal conditions. Whether corticosteroid substitution can be limited to patients with inadequate response to COC on plasma androgen levels or with signs of adrenal insufficiency requires further data.

[Sexual functions after laparoscopically assisted vaginal hysterectomy (LAVH) and total laparoscopic hysterectomy (TLH) in preoperatively asymptomatic women]

OBJECTIVE

To find the consequences of laparoscopically assisted vaginal hysterectomy (LAVH) and total laparoscopic hysterectomy (TLH) for sexual functions in preoperatively asymptomatic women.

DESIGN

Prospective study.

SETTING

Department of Obstetrics and Gynecology, 1st Faculty of Medicine, Charles University and General Teaching Hospital in Prague.

MATERIAL AND METHODS

In 100 women without subjective complaints hysterectomy was performed for benign uterine pathology. In all the women the uterus weighted less than 250 g, there were no salpingooophorectomies and no perioperative complications. Women were alternativelly assigned for LAVH (n = 50) or TLH (n = 50). Clinical documentation and questionnaires about sexual functions were evaluated in 87 women (in 40 women after LAVH and in 47 after TLH) 18 months after surgery or later.

RESULTS

According to our findings the type of surgery did not influence the frequency of sexual activity after surgery, there was no change in sexual manners using during coitus as well as no change in preferred way how to reach the sexual arousal (clitoridally, vaginally or combined). The type of surgery did not influence frequency, quality and duration of orgasm. From all the evaluated parameters there were only two significantly different: the presence of postoperative sexual activity (positive answer in all women from LAVH group and only in 85% women from TLH group, F test, p = 0.009) and the frequency of sexual satisfaction (in terms of both increase and also decrease in TLH group chi2 8,376, p = 0.015).

CONCLUSION

The type of laparoscopic hysterectomy (LAVH or TLH) does not significantly affect the sexual functions (frequency of sexual satisfaction, type of sexual arousability, intensity and duration of orgasm) in preoperatively asymptomatic women.

Prevalence of nonclassic adrenal hyperplasia (NCAH) in hyperandrogenic women

OBJECTIVE

The clinical symptoms of nonclassic adrenal hyperplasia (NCAH) are identical with polycystic ovary syndrome (PCOS). The aim of our study was to determine the prevalence of nonclassic adrenal hyperplasia (21-hydroxylase-deficiency) in hyperandrogenic women, its biochemical, endocrine and clinical characteristics and to compare them with parameters of patients with ovarian hyperandrogenism.

METHODS

Since 1999, 298 patients with elevation of at least one androgen and manifestation of one of the clinical androgenic symptoms (oligo/amenorrhea, hirsutism or acne) have been identified in our database. A diagnosis of NCAH was considered when the basal or stimulated 17-hydroxyprogesterone was elevated.

RESULTS

Only eight patients were identified as having 21- hydroxylase deficient NCAH in the whole group of 298 hyperandrogenic women. Hirsutism and acne were found only in three, two patients, five of them had oligo/amenorrhea. Seven patients had both elevated basal and stimulated 17-hydroxyprogesterone, while in one case only elevation of stimulated level was found. All of the NCAH patients had elevated concentrations of testosterone, six DHEA, lower SHBG was found in four patients. Surprisingly, none of the NCAH patients had increased DHEAS.

CONCLUSION

In our study, the prevalence of NCAH in hyperandrogenic women was 2.68%. Their leading symptom was oligomenorrhea, skin androgenic disorders were a minor clinical problem. None of the NCAH patients had an elevated DHEAS, the androgen dominantly produced by the adrenal glands.

Uterine arteries doppler velocimetry provides 3-years follow up endometrial ablation outcome

The aim of this study was to assess whether uterine artery Doppler velocimetry [pulsatility index (PI) and resistance index (RI)] and thickness of the endometrium (TE) are able to predict 3-year clinical outcome after endometrial ablation (EA) for dysfunctional uterine bleeding (DUB). This was a prospective, observational study of 29 women of whom 22 were amenorrhoeic (A) and 7 eumenorrhoeic (E) at the end of the first postoperative year. The PI, RI and TE were measured prior to and 1, 6 and 12 months after EA. Statistical analyses were performed using BMDP statistical software, discriminant analysis, ANOVA and T test. Using the calculated classification function (CF) with the three parameters PI, RI and TE measured 12 months after FEAT, we were able to accurately (100%) specify which of the women will have A or E in 3 years. The predictive value of PI, RI and TE has been confirmed clinically in a minimum 3-year follow-up of outcome (ranging from 36 to 72 months [mean 55]). All A and E women have stayed in the same group (A or E) during the minimum of 3 years. In conclusion we found that PI, RI and TE measured prior to EA cannot predict the outcome, however these measurements performed 1 year after FEAT can predict the duration of A or E in the 3-year follow up.

[Late (non-classic) adrenal hyperplasia]

OBJECTIVE

To summarize available data concerning adrenal hyperandrogenemia caused by 21-hydroxylase deficiency, non-classic adrenal hyperplasia (NCAH).

DESIGN

Review article.

SETTING

Department of Gynecology and Obstetrics, General Faculty Hospital and 1st Medical Faculty, Prague.

METHODS

Compilation of published data from scientific literature.

CONCLUSION

Although 21-hydroxylase deficiency is one of the most frequent autosomal recessive genetic disorders, prevalence of NCAH in the whole population and among hyperandrogenic women is very low. The measurement of 17OH-progesterone should be incorporated into the standard evaluation of all hyperandrogenic patients to establish or exclude the diagnosis of NCAH. There is no typical clinical sign of NCAH, and clinical symptoms are to similar to patients with PCOS. Corticoid substitution as a treatment modality of NCAH is derived from therapy of classic congenital adrenal hyperplasia (CAH). Anti-androgen therapy is effective in skin disorders (hirsutism). Due to normal cortisol value there is to use of combined oral contraceptives in the treatment of choice. An improvement of clinical symptoms is a key parameter for the evaluation of treatment effectiveness. There are no data about risk of late metabolic complications in NCAH patients.

[Benefits and risk of the modern combined hormonal contraception]

The combined hormonal contraception is the most efficient reversible variety of family planning. The modern low doses combined hormonal contraception have a high efficacy with minimal risks. Users are still in risks of cardiovascular complications. The combined hormone contraception also has positive noncontraceptive effects on menstrual disorders, hyperandrogenism, cysts of ovary, pelipathy etc. The benefits are higher than the risks only when respecting the basic rules of the combined hormonal contraception prescription.

The effect of combination therapy with metformin and combined oral contraceptives (COC) versus COC alone on insulin sensitivity, hyperandrogenaemia, SHBG and lipids in PCOS patients

BACKGROUND

Neither oral contraceptives (COC) nor metformin are an optimal modality for the long-term treatment of polycystic ovary syndrome (PCOS). The aim of this study was to evaluate whether a combination of both is beneficial over COC monotherapy.

METHODS

Altogether, 30 women were included in the study and 28 finished the protocol. The patients were randomly assigned to two groups treated with either COC (COC group) or COC and metformin (1500 mg/day) (METOC group) for 6 months. Anthropometric parameters, androgens, lipids, fasting insulin, glucose and sex hormone binding globulin (SHBG) concentrations were measured before and at the end of the sixth cycle of treatment. The insulin sensitivity index was evaluated using the euglycaemic clamp.

RESULTS

There were no significant changes in anthropometric parameters, fasting glucose or insulin sensitivity in either group. Total testosterone, free androgen index, androstenedione and dehydroepiandrosterone decreased and SHBG increased significantly in both groups. When comparing the effect of both treatments, only a more pronounced decrease in free androgen index was found in the METOC group.

CONCLUSIONS

Adding metformin slightly modified the treatment effect of COC, causing a more significant decrease in the free androgen index but having no additional positive impact on lipids, insulin sensitivity, SHBG or testosterone. The available data do not offer enough evidence to advocate the standard use of combined treatment in PCOS. Whether the combination might be beneficial for specific subgroups of patients is of further interest.

Insulin sensitivity in women with polycystic ovary syndrome

The aim of our study was to compare insulin sensitivity in lean and obese European polycystic ovary syndrome (PCOS) women with lean healthy women. We performed the euglycemic hyperinsulinemic clamp in 83 women with PCOS [53 lean with body mass index (BMI) of 21.5 +/- 1.8 kg/m2 and 30 obese with BMI of 29.6 +/- 3.7 kg/m2] and in 15 healthy women with BMI of 21.6 +/- 1.8 kg/m2 to determine glucose disposal (M) and the insulin sensitivity index (ISI). Statistical evaluation was done using Kruskal-Wallis ANOVA followed by Kruskal-Wallis multiple-comparison z-value test. The basal blood glucose was significantly higher in lean and obese PCOS women than in controls (P < 0.02). Fasting insulin was significantly higher in both lean and obese PCOS women than in controls (P < 0.000001). Obese PCOS women were more insulin resistant than controls (P < 0.02 for M and P < 0.0008 for ISI); lean PCOS women did not differ from controls in M or ISI. Posthepatic insulin delivery was significantly higher in both lean and obese PCOS women compared with controls (P < 0.000008). We conclude that lean PCOS women are not more insulin resistant than healthy controls. Insulin hypersecretion, on the other hand, is present even in lean PCOS women.

[A transdermal form of combined hormonal contraceptives (EVRA)]

OBJECTIVE

To present a review of a novel transdermal contraceptive patch containing norelgestromin (150 micrograms/d) and ethinylestradiol (20 micrograms/d).

DESIGN

Review article.

SETTING

Department of Gynecology and Obstetric, 1st Medical Faculty and General Faculty Hospital, Prague.

RESULTS

The contraceptive patch exhibits favourable pharmakokinetic profile, maintaining efficacious serum hormone concentrations under varying conditions and without peaks and through characteristic of oral dosing. Efficacy, cycle control, tolerability and side effect profile were comparable to an established oral contraceptive. Compliance with the weekly administered contraceptive patch was significantly better than with an oral contraceptive. The reliability of adhesion of the patch is very high and consistent even under varying conditions (heat, humidity, exercise).

Pregnancy outcome in women with PCOS and in controls matched by age and weight

BACKGROUND

The aim of this study was to compare the pregnancy outcome, especially the prevalence of gestational diabetes mellitus (GDM), in a group of patients with polycystic ovary syndrome (PCOS), with a group of healthy weight-matched women.

METHODS

Retrospectively, we evaluated the pregnancies of 66 women with PCOS, who had been treated for infertility and who delivered at our department. These were compared with a group of 66 age- and weight-matched controls.

RESULTS

We did not find any significant differences in the prevalence of pregnancy complications such as gestational diabetes mellitus, pregnancy-induced hypertension (PIH) and premature deliveries between the group of PCOS patients and the controls.

CONCLUSION

When differences in age and weight between PCOS patients and controls are negligible, PCOS is not associated with a higher risk of pregnancy complications.

[Long-term follow-up after complete treatment of peritoneal endometriosis with the CO2 laser]

OBJECTIVE

To evaluate the effect of laparoscopic CO2 laser ablation of peritoneal endometriosis in the treatment of pelvic pain with a long-term follow-up. To differentiate the effect of surgery on different types of pelvic pain.

DESIGN

Prospective observational study.

SETTING

Department of Obstetrics and Gynecology, 1st Medical Faculty, Charles University and General Faculty Hospital, Prague.

METHODS

Patients with 1st to 3rd stage endometriosis, with manifestation of pelvic pain, and with complete excision of peritoneal endometriosis lesions, were included in the study. All visible lesions were vaporized by CO2 laser following adhesiolysis and complete visualization of the pelvis. After the procedure, patients were followed up at 6-month intervals. The severity of pelipathia, dyspareunia, dysmenorrhea, pain during micturition, and pain during defecation were monitored using a visual analog score of 10 points.

RESULTS

A total of 31 patients were included in the study. After 6, 12, and 18 months after surgery, the recurrence of pelvic pain was found in 12 (39%), 15 (48%), and 19 (61%) patients, respectively. Improvement or disappearance of complaints was documented 18 months after the surgery in 11 cases of dysmenorrhea (50%), 9 cases of dyspareunia (50%), 14 cases of pelipathia (58%), 12 cases of pain during micturition (71%), and in 14 cases of pain during defecation (87.5%). The proportion of recurrences increases with the length of the interval after the procedure, mainly in dysmenorrhea and dyspareunia.

CONCLUSIONS

The effect (improvement or disappearance of pelvic pain) of a complete CO2 laser ablation of peritoneal endometriosis continues 18 months after the surgery in about 40% of patients. A graduated increase in the number of recurrences is apparent during follow-up, most significantly in dysmenorrhea and dyspareunia. The effect of surgery on different types of pelvic pain varies. A small number of recurrences was found in pain during micturition and pain during defecation, on the other hand, less success was apparent in the treatment of dysmenorrhea.

Prediction of insulin sensitivity in nonobese women with polycystic ovary syndrome

Insulin resistance is a frequent (although not constant) abnormality in both obese and nonobese women with polycystic ovary syndrome (PCOS). It plays a key role in the predisposition to type 2 diabetes, which is the most important health consequence of the syndrome. Identification of patients with insulin resistance is significant both for follow-up and for therapeutic reasons. The aim of the study was to evaluate the relationships between insulin sensitivity, measured by euglycemic clamp, and both endocrine and metabolic indices and to identify the best model for predicting insulin sensitivity. A total of 41 nonobese women fulfilling the diagnostic criteria for PCOS were enrolled in the study. None of the androgens correlated with the insulin sensitivity index. All clamp parameters correlated with SHBG, triglycerides, and body mass index, although no correlation was found with waist to hip ratio or waist circumference. The close relationship between insulin sensitivity and SHBG was documented by factor analysis and by its presence in all prediction models as the most significant (or even the single) predictor of the insulin sensitivity index.

IN CONCLUSION

1) a decreased level of SHBG can be used as a single reliable parameter in the prediction of insulin sensitivity in nonobese women with PCOS; and 2) waist to hip ratio, waist circumference, and androgen concentrations have no predictive value.

Insulin sensitivity in non-obese women with polycystic ovary syndrome during treatment with oral contraceptives containing low-androgenic progestin

BACKGROUND

Combined oral contraceptives (COC) effectively suppress hyperandrogenism in women with polycystic ovary syndrome (PCOS), though deterioration of insulin sensitivity during treatment is assumed. The study aim was to investigate insulin action and androgen production during treatment with COC containing low-androgenic progestin.

METHODS

A total of 13 PCOS women and nine controls was enrolled into the study. Only non-obese women with a body mass index (BMI) <or=30 kg/m(2) were included. Hyperinsulinaemic euglycaemic clamp techniques were performed before and after 6 months of treatment with a monophasic COC containing norgestimate.

RESULTS

Anthropometric parameters [BMI, waist:hip ratio (WHR)] remained unaltered during the study in both groups. No deterioration in glucose disposal rate (M), insulin sensitivity index (ISI) or metabolic clearance rate of glucose (MCRG) was observed during treatment in PCOS subjects. Fasting glucose decreased significantly (P < 0.01), but fasting insulin remained unchanged. Significant decreases in concentrations of testosterone (P < 0.001), androstenedione (P < 0.01) and dihydroepiandrosterone (DHEA) (P < 0.001), a decrease in the free androgen index, and an increase in concentrations of sex hormone-binding globulin were found in PCOS subjects.

CONCLUSIONS

The norgestimate-containing COC significantly decreased androgen production and concentrations of free androgens, without reducing insulin sensitivity in non-obese PCOS subjects.

[Can hormonal contraceptives affect plasma levels of IGF-1 and IGFBP-1 in slim women with polycystic ovary syndrome?]

BACKGROUND

Polycystic ovary syndrome (PCOS) represents a frequent endocrinopathy among fertile women. Ethiopathogenesis of the syndrome is multifactorial and it is a subject of scientific discussions. Considered is the possibility of intraovarial IGF system disorder affecting maturation of ovarial folicles. The aim of our work was to determine effects of peroral contraceptives with low-androgen progestin on IGF system in PCOS patients and healthy woman controls.

METHODS AND RESULTS

14 patients fulfilling diagnostic criteria of PCOS and 7 healthy controls were included into the study. All persons were examined before and after six months lasting administration of monophasic estrogen-progesteron contraceptive therapy with 35 micrograms of ethinylestradiol per day and 250 micrograms of low-androgen progestin norgestimate per day. In PCOS patients low increase of basal insulinemia levels occurred (16.3 +/- 4.8 vs. 20.8 +/- 4.8 mU.l-1, p < 0.05). IGF-1 serum levels were not influenced (230 +/- 70 vs. 235 +/- 112 pg.ml-1, n.s.), IGFBP-1 serum concentration significantly increased (46.3 +/- 24.1 vs. 75.6 +/- 24.0 pg.ml-1, p < 0.001). Insulinemia in healthy women also slightly increased (15.9 +/- 4.0 vs. 18.4 +/- 4.0 pg.ml-1, p < 0.05). IGF-1 serum concentration significantly increased (140 +/- 65 vs. 241 +/- 89 pg.ml-1, p < 0.001). IGFBP-1 was also higher (45.0 +/- 19.19 vs. 80.0 +/- 15.6 pg.ml-1, p < 0.001). Influence of the hormonal contraception on the followed parameters was estimated using Wilcoxon's test. While BP-1 increase was significant in both groups, the increase of IGF-1 was significant only in healthy controls.

CONCLUSIONS

Increased levels of IGFBP-1 were found in both studied groups of women. Women with PCOS had higher serum levels of IGF-1 before the therapy and the treatment did not influence it. Contrary to it, in healthy women the increased value was observed. Explanation of that finding will become the aim of our next study.

Production, characterization, and epitope mapping of monoclonal antibodies against human polydeoxyribonucleotide kinase

Polydeoxyribonucleotide kinase (PNK) is a mammalian DNA repair enzyme that has the capacity to phosphorylate 5' DNA termini and dephosphorylate 3' DNA termini. A series of murine monoclonal antibodies (MAbs) was raised against the full-length recombinant human PNK. Seven of these antibodies were selected and characterized by enzyme immunoassay, Western blot analysis, and their capacity to immunoprecipitate PNK. The epitope location was defined by cyanogen bromide digestion and by using a truncated PNK for Western blot analysis. All of the MAbs recognize a single 60-kDa protein in human cell extracts. PNKs from calf, monkey, and Chinese hamster cell and tissue extracts were also detected by some or all of the MAbs. These antibodies can be successfully used for the cellular, biochemical, and functional analysis of PNK in different mammalian cell lines.

Does obesity diminish the positive effect of oral contraceptive treatment on hyperandrogenism in women with polycystic ovarian syndrome?

Polycystic ovarian syndrome (PCOS) is an obvious indication for long-term treatment. Combined oral contraceptives (COC) remain the first choice for the treatment of hyperandrogenism in most patients. However, differences in endocrine and metabolic parameters between obese and lean patients have been postulated. This is the first study evaluating the effect of COC treatment in obese versus non-obese PCOS patients. In total, 28 lean [body mass index (BMI) <25 kg/m(2))] and 15 obese (BMI >30 kg/m(2)) women patients were enrolled in the study. The concentrations of androgens, sex hormone-binding globulin (SHBG) and lipids were measured before and after 6 months of treatment with COC containing low-androgenic progestins. Clinical androgenic symptoms were monitored. There was a lower concentration of SHBG in obese patients, but there were no differences in androgen concentrations between both groups before the study. Highly significant changes in concentrations of testosterone (P < 0.001), androstenedione (P < 0.0001), SHBG (P < 0.001) and LH (P = 0.01) were demonstrated in lean patients, with only less significant changes in SHBG (P < 0.01) and testosterone (P < 0.05) in obese patients during the study. Clinical androgenic symptoms improved significantly (P = 0.05) only in the group of lean women. No reduction in low-density lipoprotein-cholesterol/high-density lipoprotein-cholesterol ratio was observed in either group. In conclusion, the positive effect of COC treatment on androgen production, serum androgen binding capacity, and clinical androgenic symptoms was negatively influenced by an increased BMI.

The role of androgens in determining acne severity in adult women

BACKGROUND

Although many arguments have been put forth supporting the role of androgens in the aetiology of acne, their part in determining the severity of the disease is not well established.

OBJECTIVES

The aim of our study was to evaluate the relationship between acne severity and the clinical and laboratory markers of androgenicity in a large group of patients.

METHODS

Ninety women over 17 years of age with acne were enrolled into the study. The levels of testosterone, androstenedione, dehydroepiandrosterone, dehydroepiandrosterone sulphate and sex hormone binding globulin (SHBG) were measured. Menstrual cycle regularity, hirsutism score, acne severity and ultrasound evaluation of polycystic ovaries were recorded. One-way analysis of variance, chi(2)-test and correlation analysis were used for data processing.

RESULTS

Hirsutism was documented in 19 (21%) subjects, elevated levels of at least one androgen in 73 (81%) subjects, an irregular cycle was reported by 43 (48%) women, and polycystic ovaries were found in 45 (50%) women. The patients were divided into three groups according to acne severity. Acne was graded using the Leeds technique as minor in 43 (48%) cases, mild in 27 (30%) and moderate in 20 (22%). We did not demonstrate a positive correlation between the grade of acne severity and any of the clinical or laboratory markers of androgenicity assessed. On the contrary, women with a higher grade of acne severity showed lower values of the index of free testosterone, a lower hirsutism score and higher SHBG levels.

CONCLUSIONS

Our study suggests that the severity of acne manifestation in adult women is not determined by androgen production.

Increased risk of non-insulin dependent diabetes mellitus, arterial hypertension and coronary artery disease in perimenopausal women with a history of the polycystic ovary syndrome

The aim of the study was to determine the prevalence of non-insulin dependent diabetes mellitus (NIDDM), arterial hypertension, coronary artery disease and the risk factors for these diseases in perimenopausal women with a history of polycystic ovary syndrome (PCOS) treatment. A group of 28 women was selected from a large group of patients who had undergone wedge ovarian resection. A total of 752 controls was selected by age (45-59 years) from a random female population sample. There was no difference between the two groups in body mass index, waist circumference or waist-hip ratio. Both groups were found to have identical family histories of NIDDM, hypertension, and coronary artery disease and identical smoking habits. We did not find a difference between the mean concentrations of lipids and fasting glucose. The two groups did not differ in the proportions of women with elevated lipid concentrations. The prevalence of NIDDM and coronary artery disease was significantly higher in PCOS women. In conclusion, women in the general population have the same level of risk factors at perimenopausal age as PCOS women. Patients with markedly expressed clinical symptoms of PCOS made up a subgroup in the general population at high risk for developing NIDDM and coronary artery disease.
