[Guidelines for the use of GnRH-analogues in the treatment of endometriosis].

Today GnRH-Analogues are the most effective substances for the regression of endometriosis and endometriosis related complaints. In combination with add-back medication the treatment is effective with only few tolerable side effects. The different types of GnRH-Analogues are equally effective, but depot preparation have the best compliance. The tailored application of GnRH-Analogues preoperatively, postoperatively or instead of surgery is dependent on the individual situation of the patient and dependent on the proliferative activity, localisation, type and stage of the disease.

[ENZIAN-score, a classification of deep infiltrating endometriosis].

The ENZIAN-Score is presented as a new instrument to classify the deep infiltrating endometriosis. Especially the retroperitoneal part of the severe endometriosis is focussed on. In analogy to an oncological staging four different stages are pronounced. The localisation and the expansion of the endometriosis nodule was indicated to different subgroups. The still used rAFS-score is of no clinical evidence, as we pointed out in a retrospective study of our patients with severe intestinal endometriosis.

Current place of progestins in the treatment of endometriosis-related complaints.

Oral progestins have been used for the treatment of endometriosis and endometriosis-associated complaints for more than 40 years. The mechanism of action on the menstrual cycle is well understood; however, the mechanism of action on endometriosis is still a matter of debate. The different progestins are able to stop proliferation in endometriotic implants and to induce regressive change to certain degrees; they are not able to heal endometriosis because endometriosis is a chronic and recurrent disease. For this reason, no medical treatment can heal endometriosis and repeat medication is necessary in the medical management of this disease. Progestins--especially non-androgenic progestins--are well tolerated and have only few side-effects; they can be used repeatedly or continuously over a long period of time.

Diagnostic errors in interactive telepathology.

Telepathology (TP) as a service in pathology at a distance is now widely used. It is integrated in the daily workflow of numerous pathologists. Meanwhile, in Germany 15 departments of pathology are using the telepathology technique for frozen section service; however, a common recognised quality standard in diagnostic accuracy is still missing. In a first step, the working group Aurich uses a TP system for frozen section service in order to analyse the frequency and sources of errors in TP frozen section diagnoses for evaluating the quality of frozen section slides, the important components of image quality and their influences an diagnostic accuracy. The authors point to the necessity of an optimal training program for all participants in this service in order to reduce the risk of diagnostic errors. In addition, there is need for optimal cooperation of all partners involved in TP service.

Recommendations for estrogen and progestin replacement in the climacteric and postmenopause. European Progestin Club.

The diversity of function that sex steroids have proven to have in the female body, gives them a position of central importance in gynaecology. Scientific research demonstrates not only the well known genital functions of sexual steroids, furthermore, various extragenital organs are influenced and modulated by ovarian hormones. Therefore, the general benefit of HRT for the female organism becomes clearer and the clinical management of menopause is developing to a broad new discipline, the gender specific medicine. In clinical practise, phytosteroids are claimed by the patient and therefore, also of high interest for the scientific research. Also, tissue specificity of the endocrine treatment and the biological relevance of different steroid receptors of HRT are discussed, leading to the development of new HrT preparations. Individualisation, the tailoring of HRT, according to the patients needs, and low dose steroids management, will also become an important aspect in the recommendations for estrogen and progestin replacement therapy.

Progestins and uterine leiomyoma.

Myomas are the most frequent benign gynecological tumors and are responsible for several symptoms and complaints. Their etiology is unknown and their pathology and proliferation is poorly understood. Besides the importance of estrogens for development and growth of the myoma, progesterone seems to play an important role in the modulation of mitotic activity, local growth factors and growth factor receptors, as well as other paracrine mechanisms.

Impact of maternal body build characteristics on newborn size in two different European populations.

The association patterns between maternal anthropometric characteristics (stature, prepregnancy weight, prepregnancy body mass index, pregnancy weight gain) and newborn size (birth weight, length, head circumference) were tested with 10,240 single births taking place between 1985 and 1995 in Vienna, Austria, and 3,452 single births taking place between 1989 and 1995 in Westerstede-Ammerland (Friesland), northern Germany. Maternal size and newborn size differed highly significantly (p < 0.001) between the two genetically and socioeconomically different population groups. Furthermore, the incidence of macrosomia among newborns (birth weight greater than 4000 g) was extraordinarily high (17.9%) in the Frisian group from northern Germany. In both populations taller and heavier women with a higher weight gain during pregnancy gave birth to heavier offspring. Nevertheless, the pregnancy weight gain, which indicates environmental conditions of the mother, had only a minor impact on newborn size compared with stature and prepregnancy weight, which reflect the maternal genetic potential to a higher degree.

[The significance of gestagens in treatment of mastopathy].

The term "mastopathy" has yet to receive a common accepted definition. 70% of all mastopathies do not demonstrate, morphologically speaking, a proliferation, where as less than 10% show an atypical proliferation that suggests an increased risk for cancer development. The indication for the treatment of a mastopathy without proliferative processes is the existence of pain. The concurrent development of Hyperprolactinemia, Hyperandrogenemia, or Hypothyreosis and the resulting metabolic disorders that accompany such should be treated in a causal manner. Progestins have proved to be effective in cases where a progesterone deficit and/or a relative hyperestrogenism exist. An evaluation of progestins as a prophylaxis for breast carcinoma development in women with an atypical proliferation, however, can first be completed when a deeper knowledge of the local hormone situation in the breast tissue exists. Suitable in this case, are the 17-Hydroxyprogesterone derivatives, because the 19-Nortestosterone derivatives produce a negative influence on the Lipid metabolism due to their partial androgenic effect and in addition, antagonise the hepatocellular estrogen effect (IGF1-reduction and SHBG-increase), which may indirectly offer protection for the breast.

[Significance of progestins in treatment of endometriosis].

Endometriosis is a chronic benign proliferative disease with high risk of recurrences, despite of medical and/or surgical treatment. The variation and severity of symptoms reduce the quality of life, the ability of working and the sexual behaviour. Medical cure of symptoms is a central concept in the therapeutic strategy. Low dose progestins have shown to be effective in the clinical routine since several decades although scientific data are rare and insufficient about the mechanism of action of these substances. Subjective and biochemical side effects are important for the choice of a specific progestin. The dosage is dependent of the biological activity of the drug, especially the effect on the endometrium. On the endometriotic implants and cysts high dose therapy with progestins induces the same regressive changes as complete estrogen deprivation by reversible "medical castration".

Should add-back therapy for endometriosis be deferred for optimal results?

Add-back hormone replacement therapy has been shown to alleviate some of the hypo-oestrogenic side effects associated with gonadotrophin-releasing hormone agonists, including demineralisation of bone. Studies on patients with uterine fibroids have shown that concomitant add-back therapy reduced the efficacy of these agents, but that deferred administration was less detrimental. This trial set out to investigate if deferred add-back therapy could offer any advantages to patients with endometriosis compared with immediate therapy. Zoladex [goserelin acetate (3.6 mg every 4 weeks)] was given for 24 weeks either with placebo, with medrogestone (10 mg/day) for 24 weeks (immediate add-back therapy), or with placebo for 12 weeks followed by medrogestone (10 mg/day) for 12 weeks (deferred add-back therapy) to 123 patients. The number of responders measured using the Revised American Fertility Society score (decrease in this score of > or = 50%) was greatest in the immediate add-back therapy group, although there were no significant differences between groups. All three treatment groups showed significant decreases in bone mineral density compared with baseline but smaller losses were generally observed in the add-back groups. A significantly smaller number of patients in the immediate add-back group reported hot flushes during the first 12 weeks of treatment compared with the deferred add-back group. In conclusion, it appears that there is no extra advantage to patients with endometriosis being treated with goserelin in delaying the start of add-back therapy.

Autoreactive epitopes within the human alpha-enolase and their recognition by sera from patients with endometriosis.

Patients with endometriosis significantly develop autoantibodies directed against endometrial proteins, which may be involved in the aetiology of this gynaecological disease. Based on standard Western blot analysis, a 48 kDa protein was localized in the soluble protein extract of endometrial adenocarcinoma cells using sera from patients with clinically staged endometriosis and identified as the glycolytic enzyme alpha-enolase. The corresponding cDNA coding for the human alpha-enolase was isolated from a human endometrial cDNA library and cloned into the vector pH6EX3, allowing the efficient expression of recombinant human alpha-enolase with an N-terminal histidine-hexapeptide as affinity ligand in Escherichia coli. The purified recombinant human alpha-enolase was evaluated as a specific antigenic tool for the diagnostic measurement of antiendometrial antibodies in sera from patients with endometriosis. With selected endometriosis sera, two linear autoreactive epitopes were localized within the recombinant human alpha-enolase using epitope mapping techniques, and they were characterized.

[Treatment of endometriosis with the GnRH agonist buserelin (Suprecur): a multicenter study].

A phase III multicentre study was carried out with the GnRH agonist buserelin (Suprecur) at five university institutions (Dept. of Obstetrics and Gynaecology of Essen, Kiel, Tübingen, Münster and Erlangen) to evaluate the effect of Buserelin (3 x 300 micrograms daily intranasal) on endometriosis for a period of 6 months. Endometriosis was verified by light microscopy in all cases. The data of 430 patients could be evaluated. The extent of the endometriotic lesions was studied before the start and at the end of therapy. The mean age of the patients was 30 +/- 5 years. For 300 patients (66.4%) sterility was a main problem. Previous treatment for endometriosis consisted of operation in 20.5%, treatment with danazol in 16.8% and treatment with gestagens in 11.6% of the patients. Under treatment FSH changed from 11.0 +/- 31.4 mIU/ml to 7.0 +/- 5.6 mIU/ml at the end of therapy; LH from 11.1 +/- 12.9 mIU/ml to 7.4 +/- 7.3 mIU/ml; estradiol from 113.9 +/- 89.0 to 35.9 +/- 60.3 pg/ml and progesterone from 7.2 +/- 11.2 ng/ml to 0.8 +/- 1.4 ng/ml. The effect on endometriosis was judged according to the revised American Fertility Society score (rAFS 1985). The changes of the rAFS-score stages were as follows (before/after therapy): Stage 0: 0%/42.8%; stage I: 43.5%/38.5%; stage II: 31.1%/11.2%; stage III: 18.1%/2.2%; stage IV: 6.3%/0.2%. The total mean AFS-stage changed from 1.9 to 0.7. The frequency of clinical symptoms improved (before/after therapy): dysmenorrhoea 65.0%/11.2%; pelvic pain 48.2%/14.1%; pain at the time of gynaelogical examination 40.0%/9.7%.(ABSTRACT TRUNCATED AT 250 WORDS)

Goserelin (Zoladex) depot in the treatment of endometriosis. Zoladex Endometriosis Study Group.

STUDY OBJECTIVE: To evaluate the safety and efficacy of Goserelin (Zoladex depot; ICI Pharmaceuticals, Macclesfield, Cheshire, United Kingdom) in the treatment of endometriosis. DESIGN: Open study. SETTING: Eleven centers in Germany and 1 center in Austria. PATIENTS: One hundred forty-six patients with pelvic endometriosis. INTERVENTION: Goserelin (Zoladex depot) therapy, one depot (3.6 mg) subcutaneously every 4 weeks for 6 months. RESULTS: Total subjective score and total pelvic symptom score showed a reduction by 86% and 93%, respectively, at the end of the treatment and did not exceed one fifth of the pretreatment value throughout the follow-up period of 48 weeks. One hundred seven women underwent a second laparoscopy at the end of the therapy for determination of objective efficacy: 54% of the patients showed a reduction of implants and adhesions by at least 50% or more, and 31.5% had a complete resolution of visible deposits. The mean reduction of implants and adhesions was 50%, and the mean reduction of implants 72%. Twenty of 64 (31.3%) previously infertile patients successfully conceived within 12 months after discontinuation of the therapy. Goserelin led to a down regulation of the pituitary ovarian axis and as a pharmacological effect of this hypoestrogenism most patients had hot flushes and vaginal dryness. CONCLUSIONS: Zoladex depot therapy proved to be safe and effective in the medical treatment of endometriosis.

[Residual endometriosis following LHRH analog therapy].

LHRH analogue therapy has proved effective in the treatment of endometriosis. Although in the majority of patients a marked reduction in AFS implant score is observed, in some cases residual endometriotic foci are macroscopically suspected and can be confirmed by histological examination during a second check operation at the end of treatment. In the study presented, 34 patients from 69 showed residual endometriosis after a 6 months' treatment with the LHRH analogue buserelin (900 mcg/d intranasally). According to light microscopical criteria regressive changes were seen in 52% of the implanted patients, nevertheless 29% presented with proliferative elements of the disease. In 19% proliferation and regression were seen in the same biopsy or even in the same gland. Histology did not relate to either the degree of ovarian suppression by LHRH analogue therapy, or to the location of the residual endometriotic foci. These results add another piece of evidence to the fact, that endometriosis presents itself as a heterogenic disorder. In addition, susceptibility to a hormonal ablative therapy rather depends on the degree of dysontogenetic differentiation, than on the completeness of induced ovarian suppression.

[Ovarian suppression by the GnRH analog buserelin in the treatment of endometriosis. Clinical, biochemical and pelviscopic studies].

To evaluate the efficacy, safety and tolerance of the GnRH-analogue Buserelin in the treatment of endometriosis, we started a non-comparative study of 52 patients with various stages of endometriosis. The dosage of 900 mcg/d was administered 3 times daily intranasally for 6 months. The degree of the disease was evaluated before and at the end of treatment by pelviscopy and biopsy. A regression of the implant score was found in 88% of patients. The mean AFS score was reduced from 17.4 +/- 1.9 before medication to 7.2 +/- 8.2 after therapy. Endometriosis related complaints were significantly improved during treatment. After 6 months 75% of the patients were without lower abdominal pain, 98% without dysmenorrhoea, and 85% without dyspareunia. As a result of the induced low level of oestrogen, 60% of the patients claimed hot flushes, 12% sweating, reduced libido, and dry vagina. Bleeding (spotting, break-through bleeding, menstruation) occurred in 40% during the first month, and was continuously reduced during the following period. Before, during and after therapy, venous blood samples were drawn to check laboratory tests for blood count, clotting parameters, clinical chemistry, serum electrolytes, as well as liver and lipid metabolism. All values stayed within the normal range without significant changes. In the follow-up period of at least 12 months, we achieved an uncorrected pregnancy rate of 41% in the group of 34 women with primary or secondary infertility.
