ABSTRACT
BACKGROUND: Patients with breast cancer (BC) show strong interest in complementary and alternative medicine (CAM), particularly for adverse effects of adjuvant endocrine treatment - e.g., with letrozole. Letrozole often induces myalgia/limb pain and arthralgia, with potential noncompliance and treatment termination. This analysis investigated whether CAM before aromatase inhibitor (AI) therapy is associated with pain development and the intensity of AI-induced musculoskeletal syndrome (AIMSS) during the first year of treatment. PATIENTS AND METHODS: The multicenter phase IV PreFace study evaluated letrozole therapy in postmenopausal, hormone receptor-positive patients with early BC. Patients were asked about CAM use before, 6 months after, and 12 months after treatment started. They recorded pain every month for 1 year in a diary including questions about pain and numeric pain rating scales. Data were analyzed for patients who provided pain information for all time points. RESULTS: Of 1396 patients included, 901 (64.5%) had used CAM before AI treatment. Throughout the observation period, patients with CAM before AI treatment had higher pain values, for both myalgia/limb pain and arthralgia, than non-users. Pain increased significantly in both groups over time, with the largest increase during the first 6 months. No significant difference of pain increase was noted regarding CAM use. CONCLUSIONS: CAM use does not prevent or improve the development of AIMSS. Pain intensity was generally greater in the CAM group. Therefore, because of the risk of non-compliance and treatment discontinuation due to the development of higher pain levels, special attention must be paid to patient education and aftercare in these patients.

AIM OF THE STUDY: The European Society of Breast Cancer Specialists (EUSOMA) has fostered a voluntary certification process for breast centres to establish minimum standards and ensure specialist multidisciplinary care. Prospectively collected anonymous information on primary breast cancer cases diagnosed and treated in the units is transferred annually to a central EUSOMA data warehouse for continuous monitoring of quality indicators (QIs) to improve quality of care. Units have to comply with the EUSOMA Breast Centre guidelines and are audited by peers. The database was started in 2006 and includes over 110,000 cancers from breast centres located in Germany, Switzerland, Belgium, Austria, The Netherlands, Spain, Portugal and Italy. The aim of the present study is assessing time trends of QIs in EUSOMA-certified breast centres over the decade 2006-2015. MATERIALS AND METHODS: Previously defined QIs were calculated for 22 EUSOMA-certified breast centres (46122 patients) during 2006-2015. RESULTS: On the average of all units, the minimum standard of care was achieved in 8 of 13 main EUSOMA QIs in 2006 and in all in 2015. All QIs, except removal of at least 10 lymph nodes at axillary clearance and oestrogen receptor-negative tumours (T > 1 cm or N+) receiving adjuvant chemotherapy, improved significantly in this period. The desirable target was reached for two QIs in 2006 and for 7 of 13 QIs in 2015. CONCLUSION: The EUSOMA model of audit and monitoring QIs functions well in different European health systems and results in better performance of QIs over the last decade. QIs should be evaluated and adapted on a regular basis, as guidelines change over time.

OBJECTIVE: Lipids and steroid hormones are closely linked. While cholesterol is the substrate for (placental) steroid hormone synthesis, steroid hormones regulate hepatic lipid production. The aim of this study was to quantify circulating steroid hormones and lipid metabolites, and to characterize their interactions in normal and pathological pregnancies with a focus on hepatic and placental pathologies. METHODS: A total of 216 serum samples were analyzed. Group A consisted of 32 patients with uncomplicated pregnancies who were analyzed at three different time-points in pregnancy (from the first through the third trimester) and once post partum. Group B consisted of 36 patients (24th to 42nd week of gestation) with pregnancy pathologies (IUGR n = 10, preeclampsia n = 13, HELLP n = 6, intrahepatic cholestasis n = 7) and 31 controls with uncomplicated pregnancies. Steroid profiles including estradiol, progesterone, and dehydroepiandrosterone were measured by GC-MS and compared with lipid concentrations. RESULTS: In Group A, cholesterol and triglycerides correlated positively with estradiol (cholesterol ρâ=â0.50, triglycerides ρâ=â0.57) and progesterone (ρâ=â0.49, ρâ=â0.53) and negatively with dehydroepiandrosterone (ρâ=â-â0.47, ρ = -â0.38). Smoking during pregnancy affected estradiol concentrations, leading to lower levels in the third trimester compared to non-smoking patients (p < 0.05). In Group B, cholesterol levels were found to be lower in IUGR pregnancies and in patients with HELLP syndrome compared to controls (p < 0.05). Steroid hormone concentrations of estradiol (p < 0.05) and progesterone (p < 0.01) were lower in pregnancies with IUGR. DISCUSSION: Lipid and steroid levels were affected most in IUGR pregnancies, while only minor changes in concentrations were observed for other pregnancy-related disorders. Each of the analyzed entities displayed specific changes. However, since the changes were most obvious in pregnancies complicated by IUGR and only minor changes were observed in pregnancies where patients had impaired liver function, our data suggests that placental rather than maternal hepatic function strongly determines lipid and steroid levels in pregnancy.
ABSTRACT
Introduction: Ductal carcinoma in situ (DCIS) is a premalignant lesion of the glandular component of the breast and a precursor lesion of invasive breast cancer. In recent decades the incidence of DCIS has risen continuously, mainly because of more extensive screening and more advanced diagnostic procedures. There is an increasing need for evidence-based treatment guidelines which will protect patients as far as possible from recurrence or invasive cancer but also from overtreatment. This retrospective single-center clinical trial analyzed recurrence-free survival times, rates of invasive and non-invasive events, and the impact of patient history, histopathological variables and therapeutic factors on recurrence-free survival times. Material and Methods: A total of 200 patients who underwent surgery between 2000 and 2007 for pure DCIS were included in the study. As part of follow-up a questionnaire was sent to patients and their respective gynecologists. Results: In the follow-up period, 12.5â% (n = 25) of the 200 patients had recurrence (invasive or non-invasive event). Menopausal status, tumor grade and tumor size were significantly associated with recurrence. Low-grade DCIS was significantly more often hormone receptor-positive than high-grade DCIS. Patients who had postoperative radiotherapy significantly more often also received endocrine drug treatment. There was a significant association between younger patient age and drug treatment. The study found that in the investigated cohort, premenopausal women had a significantly shorter recurrence-free time compared to postmenopausal women. Conclusion: This paper summarizes the current literature on DCIS. There is a need for more prospective clinical trials to improve the prognosis of premenopausal women with large and hormone receptor-positive DCIS.
ABSTRACT
OBJECTIVES: Is the saliva test, Geratherm ovu control, as accurate as the established urinary luteinizing hormone (LH) test for detecting ovulation and the following the fertile period? STUDY DESIGN: The voluntary participants were 74 healthy women with regular menstrual cycles and not using any hormonal contraceptives. The women used Geratherm ovu control, a small plastic hand-held microscope, for detecting the fertile period. A drop of saliva from sublingual was put onto the lens of the microscope. Three results were possible: non-fertile (dot pattern), transitional and fertile (ferning pattern). The participants performed the saliva test from the 5th till the 22nd day of the menstrual cycle and noted the respective result in a table. In addition to Geratherm ovu control, the EXACTO test for determining urinary LH concentration and the time of peak fertility was also performed. RESULTS: Positive LH shows a sharp increase beginning on the 10th cycle day with a maximum on the 17th cycle day. The curve for positive saliva and questionable positive saliva (one curve) is almost parallel with the curve for positive LH, reaching a maximum on the 16th cycle day. There is a high level of conformity for the same test results from the 5th (100%) till the 14th (84%) cycle day and from the 18th (80%) till the 22nd (96%) cycle day which corresponds to the pre- and post-ovulatory period. CONCLUSION: The saliva and the LH test both detect the fertile window of a menstrual cycle. Caused by the different hormones (estrogen for the saliva and LH for the LH test) leading to the respective positive test results, saliva turns positive 24h before LH. Consequently, the saliva test can be used as an ovulation test and help women maximize their chances of conceiving. There is also a high congruence between LH and saliva in the pre- and post-ovulatory period, indicating that the saliva test can also be used for contraception purposes.

AIM OF THE STUDY: The European Society of Breast Cancer Specialists (EUSOMA) has fostered a voluntary certification process for breast units to establish minimum standards and ensure specialist multidisciplinary care. In the present study we assess the impact of EUSOMA certification for all breast units for which sufficient information was available before and after certification. MATERIALS AND METHODS: For 22 EUSOMA certified breast units data of 30,444 patients could be extracted from the EUSOMA database on the evolution of QI's before and after certification. RESULTS: On the average of all units, the minimum standard of care was achieved for 12/13 QI's before and after EUSOMA certification (not met for DCIS receiving just one operation). There was a significant improvement of 5 QI's after certification. The proportion of patients with invasive cancer undergoing an axillary clearance containing >9 lymph nodes (91.5% vs 89.4%, p 0.003) and patients with invasive cancer having just 1 operation (83.1% vs 80.4%, p < 0.001) dropped, but remained above the minimum standard. The targeted standard of breast care was reached for the same 4/13 QI's before and after EUSOMA certification. CONCLUSION: Although the absolute effect of EUSOMA certification was modest it further increases standards of care and should be regarded as part of a process aiming for excellence. Dedicated units already provide a high level of care before certification, but continuous monitoring and audit remains of paramount importance as complete adherence to guidelines is difficult to achieve.

For the first time, this year's St. Gallen International Consensus Conference on the treatment of patients with primary breast cancer, which takes place every two years, was held not in St. Gallen (Switzerland) but - for logistical reasons - in Vienna (Austria) under its usual name. The 2015 St. Gallen International Consensus Conference was the 14th of its kind. As the international panel of the St. Gallen conference consists of experts from different countries, the consensus mirrors an international cross-section of opinions. From a German perspective, it was considered useful to translate the results of the votes of the St. Gallen conference into practical suggestions, particularly in light of the recently updated treatment guideline of the Gynecologic Oncology Group (AGO-Mamma 2015) in Germany. A German group consisting of 14 breast cancer experts, three of whom are members of the international St. Gallen panel, has therefore provided comments on the results of this year's votes at the 2015 St. Gallen Consensus Conference and their impact on clinical care in Germany. The 14th St. Gallen conference once again focused on surgery of the breast and the axilla, radio-oncologic and systemic treatment options for primary breast cancer depending on tumor biology, and the clinical use of multigene assays. The conference also considered targeted therapies for older and for younger patients, including the diagnosis/treatment of breast cancer during and after pregnancy and the preservation of fertility.
ABSTRACT
The therapy for patients with breast cancer has developed markedly in the past ten years. Our understanding of the molecular biology of tumours and the characteristics of the patients has shaped the recent advances. In this review we present the latest knowledge about the therapy for breast cancer. There are new tests and options not only in the field of anti-HER2 therapy but also in the management of triple negative and hormone receptor-positive patients. Comprehension of prognosis and therapeutic response to chemotherapies is little by little helping to define patient groups who will not respond to chemotherapy or who do not need treatment because their prognosis is extremely good. In the field of anti-HER2 therapy, work is continuing on the development of drugs suitable for and able to overcome trastuzumab resistance. For hormone receptor-positive cancers, we now have a better understanding of which therapy groups will benefit from which anti-endocrine drugs, and which will be able to overcome a possible resistance (treatment of the PI3K pathways, inhibition of the cell cycle). Molecular tests are still being evaluated with regard to the clinical situations in which they may have the greatest relevance for therapeutic decision-making; however, evidence is also increasing as to the fields in which good predictions for the prognosis can be obtained. On the whole, more work is needed to promote our understanding of the new developments in diagnostics and therapy and to involve both physicians and patients equally in the procedures.
ABSTRACT
OBJECTIVE: Misoprostol is safe and effective for labor induction in viable pregnancies. Little is known about the prevalence of off-label use of misoprostol, and the reasons for using or not using misoprostol for labor induction. As such, a national survey was conducted in Germany to assess reliable data about the use of misoprostol in clinical practice. STUDY DESIGN: A prospective study was performed in 2013 using a standardized survey questionnaire. All registered departments of obstetrics and gynecology in Germany were targeted. RESULTS: Out of 783 questionnaires, 542 (69%) were returned. Three hundred and fifty-five (66%) respondents reported that they use misoprostol for labor induction in viable term pregnancies, and 183 (34%) respondents reported that they never use misoprostol for this indication. The most common reasons given for using misoprostol in labor induction were: effectiveness (40%), good patient acceptance (35%), established/well proven in clinical practice (35%) and cost-effectiveness (32%). The most common reasons given for not using misoprostol were lack of licence (off-label use, 69%) and uncertainty of the legal situation (27%). CONCLUSION: Although misoprostol is not licensed in Germany for obstetric indications, the vast majority of respondents (66%) reported that they use misoprostol for labor induction. The main reasons for not using misoprostol for labor induction in Germany are legal concerns rather than lack of scientific evidence. Cost-effective medications with evidence-based effectiveness and safety should be supported by a clear statement from national medical societies.

PURPOSE: To investigate the feasibility of measuring cervical length by transabdominal and transperineal ultrasound as alternatives to transvaginal ultrasound. MATERIALS AND METHODS: 33 pregnant women with and 28 without cervical insufficiency at 16 to 35 weeks of gestation were examined by an experienced examiner (DEGUM II) and the cervical length was measured twice at an interval of 6 months. Comparability, reliability and comfort of the patients during the examinations were taken for statistical analysis. RESULTS: There is poor agreement between transabdominal and transvaginal ultrasound (Lin's rho = 0.578), whereas transperineal ultrasound shows high correlation (Lin's rho = 0.922) to the measurements obtained transvaginally, a preference referring to the comfort scale and good reliability (ICC = 0.949). When regarding sub-groups (pregnant women with and without cervical insufficiency), transperineal ultrasound shows better results than transabdominal ultrasound. However, small cohort sizes affect the statistical validity. CONCLUSION: Transabdominal ultrasound cannot be recommended to measure cervical length. Besides providing exact measurements, transperineal ultrasound avoids contact between the cervix and the probe, is better accepted by patients and offers a simplified examination. This method is a good alternative to transvaginal ultrasound. Due to minor inaccuracies of the method, we recommend this technique only for patients with a cervix longer than 2.5 cm. For further analysis concerning patients with cervical insufficiency, large-scale studies should be performed.

OBJECTIVES: To examine the performance of a new reference line for the assessment of pelvic organ descent by transperineal ultrasound. METHODS: We compared our newly proposed reference line, between two hyperechoic contours of the symphysis pubis (Line 3), with the horizontal reference line proposed by Dietz and Wilson (Line 1) and the central pubic line proposed by Schaer et al. (Line 2). Ultrasound volumes of 94 women obtained in routine clinical practice were analyzed. The perpendicular distance from the reference lines to the internal sphincter and the most dependent part of the bladder base was measured for volumes obtained at rest, on pelvic floor muscle contraction, on Valsalva maneuver and during coughing. Measurements were repeated 4 months later by the same examiner. Rates of assessment were calculated, and intrarater reliability was evaluated using Bland-Altman plots and intraclass correlation coefficients. RESULTS: Line 2 had to be excluded from reliability analysis because of an assessment rate of only 12%, whereas Lines 1 and 3 could be assessed in 100% of volumes. The intrarater repeatability of Lines 1 and 3 was shown to be very similar. CONCLUSION: In this comparison of three potential reference lines for the assessment of pelvic organ descent by transperineal ultrasound, the central pubic line was shown to be inferior owing to poor visibility in our volumes. Inter-rater reliability analysis and validation studies are required to confirm our results.

INTRODUCTION: Reduced serum LDL concentrations have been observed in pregnancies complicated by intrauterine growth restriction (IUGR) as compared to healthy pregnant women. Since increased oxidative stress has been suggested to play a major role in IUGR we now hypothesized that the lower LDL concentrations are accompanied by an accumulation of oxidized LDLs in the placenta. METHODS: Fifteen placentas of near term and preterm born IUGR, and a gestational age matched control group (CTRL n = 15) were analyzed. Placental minimal modified LDL and fully oxidized LDL particles were measured by ELISA, and by immunohistochemistry, and were related to maternal and fetal serum lipid profiles. RESULTS: We found fully oxidized LDL but not minimal modified LDL being increased in the preterm subgroup of IUGR (n = 10) as compared to preterm CTRL (n = 10; p < 0.05). An increased staining intensity of trophoblasts in preterm IUGR subjects as compared to preterm CTRL has been confirmed by immunohistochemistry (p < 0.05). No difference could be found between the term groups (n = 5 each). Correlation analysis revealed an inverse relationship of maternal LDL (ρ = −0.49, p = 0.03) and fetal HDL cholesterol (ρ = −0.46, p = 0.04) with placental fully oxidized LDL particle concentration within preterms. DISCUSSION: IUGR is a heterogeneous entity. Different pathomechanisms seem to underlie the disease in preterm and term subjects with oxidation of LDL within the placenta possibly taking place in preterm IUGRs. CONCLUSIONS: We conclude that the reduced maternal LDL cholesterol concentration in IUGR pregnancies is attributed to increased accumulation of oxidized LDL particles within the placenta at least in early onset IUGR

Aim: Around half of all women in Germany with breast cancer are older than 65 and approximately one third of them is older than 70 years of age. In theory, the preferred therapeutic management of women with breast cancer aged 65 and above corresponds to that formulated for younger patients and complies with the S3 Guidelines and the therapy recommendations formulated by AGO. To study the current therapies used to treat women with breast cancer aged 70 and above in Germany, a survey of the clinics of the German Breast Group (GBG) was done. Method: An online survey was carried out with requests sent to 599 physicians registered as principal investigators in the database of the GBG. The 12-item questionnaire was used to investigate the systematic therapeutic management of 70-year-old patients in different settings. The indication for chemotherapy was taken as a given. Results: In a neoadjuvant setting, 62â% of physicians opted for anthracycline and taxane-based therapy as did 56.6â% of physicians in an adjuvant setting. One third of physicians preferred a taxane-based therapy with the anti-angiogenesis inhibitor bevacizumab as first-line therapy for primary metastatic cancer and after anthracycline-based therapy. Capecitabine (around 30â%) and navelbine (around 20â%) were proposed as second-line neoadjuvant and adjuvant therapies after prior anthracycline- and taxane-based therapy. Conclusion: The chemotherapy regimen prescribed for women with breast cancer aged 70 and above in Germany appears to be relatively standardised and corresponds to the recommendations given in the S3 Guidelines and by the AGO Breast Committee.
ABSTRACT
BACKGROUND: Oxidised low density lipoproteins (oxLDL) are key players in the development of atherosclerotic cardiovascular diseases. Since there are similarities between the pathogenesis of preeclampsia and atherosclerosis we hypothesised an increased accumulation of oxLDL at the materno-foetal and foeto-foetal interface within the placental tissue of preeclamptic women compared to women with normotensive pregnancies (controls). Moreover, we analysed maternal and foetal serum lipid parameters. PATIENTS AND METHODS: oxLDL was determined by immunohistochemistry in placental paraffin sections of 14 women suffering from preeclampsia (30th-39th week of gestation) and compared to 28 preterm and term deliveries (25th-40th week of gestation). 10 high power fields were chosen randomly by the newCAST software and oxLDL expression was analysed via standardised methods by 2 independent and blinded investigators. Maternal and foetal triglycerides, total cholesterol, LDL cholesterol and HDL cholesterol were measured. Statistical examination was carried out by the Mann-Whitney test. RESULTS: oxLDL was found in villous trophoblast and placental endothelium. No significant differences were observed in expression intensity between preeclampsia and controls. Maternal and foetal triglyceride levels were significantly increased in preeclampsia compared to controls (pre-eclampsia mothers: 293 [SD 87.4] mg/dL, controls: 214 [SD 89.4] mg/dL, p=0.0097; preeclampsia foetuses: 26 [SD 16.6] mg/dL, controls: 18 [SD 10.4] mg/dL, p=0.0463). No significant differences in other lipid concentrations were found. CONCLUSIONS: We could not confirm our initial hypothesis of an increased oxLDL accumulation in placental tissue of preeclampsia. However, preeclampsia is a condition of dyslipidaemia affecting both maternal and foetal serum with implications for development and programming of cardiovascular diseases in later life.

Treatment options as well as the characteristics for therapeutic decisions in patients with primary and advanced breast cancer are increasing in number and variety. New targeted therapies in combination with established chemotherapy schemes are broadening the spectrum, however potentially promising combinations do not always achieve a better result. New data from the field of pharmacogenomics point to prognostic and predictive factors that take not only the properties of the tumour but also inherited genetic properties of the patient into consideration. Current therapeutic decision-making is thus based on a combination of classical clinical and modern molecular biomarkers. Also health-economic aspects are more frequently being taken into consideration so that health-economic considerations may also play a part. This review is based on information from the recent annual congresses. The latest of these are the 34th San Antonio Breast Cancer Symposium 2011 and the ASCO Annual Meeting 2012. Among their highlights are the clinically significant results from the CLEOPATRA, BOLERO-2, EMILIA and SWOG S0226 trials on the therapy for metastatic breast cancer as well as further state-of-the-art data on the adjuvant use of bisphosphonates within the framework of the ABCSG-12, ZO-FAST, NSABP-B34 and GAIN trials.
ABSTRACT
Treatment options as well as the characteristics for therapeutic decisions in patients with primary and advanced breast cancer are increasing in number and variety. New targeted therapies in combination with established chemotherapy schemes are broadening the spectrum, yet not every new, promising combination achieves a better result. New data from the field of pharmacogenomics point to prognostic and predictive factors that take not only the properties of the tumour but also the genetic disposition of the patient into consideration. Current therapeutic decision-making is thus based on a combination of classical clinical and modern molecular biomarkers. Health-economic concerns are also being taken into consideration more frequently, meaning political decisions may also become a factor. This review presents the trends over the past year.
ABSTRACT
BACKGROUND: The diagnostic options for persistent urinary incontinence following prostatectomy are limited despite incidence numbers of up to 40%. Perineal ultrasound, which is already well established in urogynecology to quantify urethral mobility, can also be used for the diagnostics of incontinence in men. The present study investigated whether there is a difference in reproducibility concerning the quantification of urethral mobility between men and women. MATERIAL AND METHODS: A total of 27 men and 27 women aged 65-85 years participated in the study. All underwent perineal ultrasound examination following standardized criteria under the three conditions of rest, contraction and a Valsalva maneuvre. Ultrasound images were taken under each condition and given to two independent examiners for evaluation. For all conditions it was recorded which of the three reference points for the quantification of urethral mobility, the urethra, internal urethral meatus and the base of the urinary bladder, could be assessed. The results were compared by means of a coefficient of agreement (p0) and the difference of the results between the two groups was validated for statistical significance using Student's t-test. RESULTS: At a t-value of 1.58 (p=0.154) there were no significant differences in the reproducibility in visualizing the three sonographic reference points, the urethra, internal urethral meatus and the base of the urinary bladder, between men and women. CONCLUSIONS: Using perineal ultrasound for quantification of urethral mobility in the diagnostics of incontinence in men after prostatectomy is just as reproducible in men as in women. For both sexes the technique is comfortable and pain-free due to the non-invasive nature. Perineal ultrasound is a cheap, non-invasive and reproducible diagnostic procedure which can be recommended for the evaluation of incontinence and the selection of a suitable surgical procedure also in men.

PURPOSE: The aim of our study was to show how using contrast inversion extends the diagnostic value of perineal ultrasound, in particular with regard to paraurethral pathologies. MATERIALS AND METHODS: To assess the practical value of contrast inversion in the daily routine, 42 women with urinary incontinence underwent perineal ultrasound examination. Pictures were converted to contrast inversion and then checked for the visibility of sonographic reference points for urogynecological measurements (urethra, meatus urethrae internus, vesical base) by two independent evaluators both in B-mode and contrast inversion. Visibility was compared using a coefficient of agreement. The results were then tested for significance. In addition, in our clinical routine we detected several paraurethral pathologies (e. g. paraurethral abscess, glandula paraurethralis, urethral diverticulum), each being presented in B-mode and contrast inversion. RESULTS: There was no significant difference between contrast inversion and B-mode with regard to the reproducibility of visibility of the three sonographic reference points. Contrast inversion was superior for depicting paraurethral pathologies and postoperative anatomical findings. CONCLUSION: With respect to routine evaluation, the two modes do not reveal any significant difference. For the sonographic evaluation of paraurethral pathologies, contrast inversion provides better contour sharpness than B-mode, suggesting a higher diagnostic value for ambiguous anatomical settings. The nature of contrast inversion nevertheless facilitates misinterpretations and requires frequent comparison with B-mode pictures. In conclusion, we propose contrast inversion as an initial screen and a refinement to established diagnostic methods, such as MRI and voiding cysturethrography, not as their substitute.

BACKGROUND: Infections with a low-risk type of human papillomavirus (HPV) may lead to genital warts. HPV targets the basal cell layer of epithelial cells. The first line of defense is the innate immune system, which provides nonspecific protection against a variety of pathogens. The antimicrobial peptides (AMPs) α- and ß-defensins, cathelicidins, psoriasin, and RNase7 are central mediators. METHODS: The expression of various α- and ß-defensins, cathelicidin LL-37, psoriasin, and RNase7 was studied in biopsy samples from 35 patients with genital warts and 25 healthy women using quantitative real-time polymerase chain reaction and immunohistochemical analysis. RESULTS: We found a significantly higher expression of the ß-defensins hBD-1 (P = .03), hBD-2 (P < 0.01), and hBD-3 (P < .001), and psoriasin (P = .001) in condylomata acuminata, compared with normal controls. The RNA and protein levels of RNase7 did not differ between infected and uninfected samples (P = .55). The α-defensins HNP 1-3, HD5, and HD6 and the cathelicidin LL-37 were scarcely detectable in normal and infected tissue. CONCLUSIONS: The differing expression of AMPs in HPV-infected, compared with noninfected, vulvovaginal biopsy samples suggests that these peptides are important in the local immune response. Curiously, hBD-1 shows a significant induction whereas RNase7 does not, which suggests differing regulation of AMPs over the course of bacterial and viral infections.
