Neonatal and Maternal Outcomes among Women with Glomerulonephritis.

BACKGROUND: The outcomes of pregnancy in women with renal diseases remain controversial. The purpose of the study was to report fetal and maternal outcomes among women with glomerular disease in comparison with healthy pregnant women and a review of the current literature on this issue. METHODS: Retrospective analysis included 72 pregnancies in 62 women with biopsy-proven glomerulonephritis (GN) (in 65.3% of cases, immunoglobulin A nephropathy was found). The control group consisted of 315 healthy pregnant women. We assessed fetal (prematurity, low birth weight, hypotrophy, fetal malformation, or intrauterine death) and maternal (gestational hypertension, preeclampsia, deterioration in kidney function, and maternal death) outcomes. Descriptive data analysis, Fisher's exact test, unpaired Student's t test, and ANOVA were performed. RESULTS: Hypertension prevalence among the GN group and controls was 76.4 and 10.2%, respectively. Preeclampsia complicated 29.2% of pregnancies among women with GN and 2.9% of controls. In 8.3% of patients, at least a 50% decrease in GFR during pregnancy was observed. Preterm delivery prevalence in the GN group and controls was 74.7 and 12.7%, respectively. Hypotrophy was diagnosed in 12.5% of cases from the GN group and 5.4% of controls. The analysis showed that low estimated glomerular filtration rate, hypertension, and proteinuria were risk factors of adverse neonatal outcomes. CONCLUSION: Women with GN are a risk factor of adverse pregnancy outcomes. As pregnancy complications are more prevalent across all the CKD stages, even in patients with near-normal kidney function, they require specialized care. It might be advisable to screen pregnant women for the presence of CKD, as especially in the early stage, it is often asymptomatic. Both hypertension and proteinuria are risk factors for neonatal and maternal complications.

The association between serum metalloproteinase concentration, obesity, and hormone levels in reproductive-aged women.

INTRODUCTION: Increased levels and activity of some matrix metalloproteinases (MMPs) are described in obesity-related vascular diseases. Factors that influence MMP blood concentration are still being investigated. This research aims to evaluate the concentration of most types of MMPs: collagenases (MMP-1, -3, -8, -13), matrilysin (MMP-7), gelatinase (MMP-9), and metalloelastase (MMP-12) in serum of women in reproductive age in relation with their body mass index (BMI), age, oestradiol, and progesterone concentrations. MATERIAL AND METHODS: Blood samples were taken from 54 healthy reproductive-aged women with normal menstrual cycles. The weight and height of all women were measured, and body mass index (BMI) was calculated. Concentration of MMP-1, -3, -7, -8, -9, -12, and MMP-13 was evaluated using a Procarta Immunoassay Kit. Serum concentrations of oestradiol and progesterone were evaluated by immunochemiluminescence (32 in the proliferative and 20 in the secretory phase of menstrual cycle). The results of the study were statistically calculated using Pearson, Spearman, and Kruskal-Wallis tests. RESULTS: Positive correlation between MMP-7, -8, -9, -12, and -13 levels and BMI was demonstrated. Significantly higher concentrations of MMPs were found especially in obese women compared to women with normal BMI. In healthy, regularly menstruating premenopausal women, MMP levels did not correlate with oestradiol and progesterone concentrations. CONCLUSIONS: The results suggest that body mass can influence MMP serum concentration in women with regular menstrual cycles.

Matrix metalloproteinases-2, -7 and tissue metalloproteinase inhibitor-1 expression in human endometrium.

INTRODUCTION: Endometrium undergoes regular, cyclic tissue remodeling mostly associated to the endocrine system status. It is well-known fact that steroid hormones are strongly responsible for changes in endometrium. The precise mechanism of their action is still under investigation. The aim of the study was to evaluate the expression of metalloproteinases 2 and 7 (MMP-2, -7) and tissue inhibitor of metalloproteinase 1 (TIMP-1) in human endometrium in relation to serum concentrations of estradiol and progesterone during different phases of menstrual cycle. MATERIAL AND METHODS: The study material consisted of 52 biopsy samples; 12 obtained in the proliferative phase, 11 in the secretory phase and 29 during menstruation. Expression of MMP-2, MMP-7 and TIMP-1 was assessed by immunohistochemistry. Serum concentrations of estradiol and progesterone at time of biopsy were evaluated by immunochemistry assay. Results of the study were statistically assessed by linear regression model. RESULTS: Increased serum concentration of estradiol was associated with increased MMP-2 expression in proliferative phase but decreased in secretory phase and during menstruation. No significant relationship was found between progesterone concentration and MMP-2 expression. Moreover, no difference in the expression of MMP-7 and TIMP-1 in the endometrium in relation to hormone levels and menstrual cycle phases were observed. CONCLUSIONS: The results of the study indicate that estradiol influence MMP-2 expression in the endometrium depends on the phase of menstrual cycle. Such relationships were not found for MMP-7 and TIMP-1 and further tests clarifying association between estradiol and MMPs are needed.

The role of metalloproteinases in endometrial remodelling during menstrual cycle.

Endometrium is the only tissue in the human body subject to cyclic transformations under the influence of ovarian steroid hormones. As estradiol and progesterone balance throughout the physiological menstrual cycle changes, so does the expression of metalloproteinases (MMPs). These endopeptides are responsible for keeping the balance between the process of synthesis and degradation of extracellular matrix proteins. Thus, MMP's take part in sustaining physiological stability of the endometrium. A number of MMPs found in the endometrial tissue and their activity is related to menstrual cycle phase. This paper is an up-to-date review of literature of Medline database. The search was conducted for key words including "matrix metalloproteinases", "MMPs", "TIMPs" and "tissue inhibitors of metalloproteinases". Over 1092 publications regarding interdependence and interplay between ovarian hormones and the role of various MMPs and their inhibitors in normal endometrial remodelling and in pathological conditions were analysed and critically reviewed.

Fetal Hypotrophy Is an Important Marker in Diagnosis of Preeclampsia in Pregnant Patients After Solid Organ Transplantation.

BACKGROUND The purpose of this study was to use a multidisciplinary approach to define the importance of fetal growth disturbances in pregnant patients after renal or liver transplantation in diagnosis and treatment of preeclampsia. MATERIAL AND METHODS We assessed 108 pregnancies in patients with renal or liver transplants. Statistical analysis included Pearson's chi-square test and Fisher's exact test. RESULTS In the renal transplant (RTR) group, preeclampsia was diagnosed in 40% according to ISSHP. In the liver transplant (LTR) group, ISSHP guidelines allow this diagnose in 14.6% of patients. Intrauterine fetal hypotrophy occurred in 53.3% of RTR patients with clinical symptoms of preeclampsia and in none of stabile patients. Premature delivery rate was 40% in patients with hypotrophy and only in 15.5% without. For LTR patients, hypotrophy was diagnosed in 16.4% patients with clinical symptoms of preeclampsia and in 12.7% of stabile patients. Premature delivery rate was 14.5% in patients with hypotrophy and in 14.5% without. CONCLUSIONS Fetal hypotrophy is strongly associated with premature delivery and risk of preeclampsia in pregnancies after renal transplantation. There is a need for including ultrasound findings in diagnostic criteria of preeclampsia. Fetal growth monitoring may help in prediction of premature delivery in these group.

Intrauterine growth restriction in pregnant women after kidney transplantation as a marker of preeclampsia.

OBJECTIVES: Delayed motherhood is associated with an increasing number of comorbidities such as glomerulonephritis, systemic lupus erythematosus, and diabetic nephropathy. Women after renal transplant belong to the group of patients who require a highly individualized approach to treatment and diagnosis. The aim of the study was to validate the commonly used diagnostic criteria for preeclampsia which seem to be irrelevant in patients with chronic renal insufficiency. MATERIAL AND METHODS: The course of pregnancy and delivery were retrospectively analyzed in 48 renal transplant patients. Two patients were excluded. Group I included 23 patients with eutrophic neonates, while Group II consisted of 23 patients with fetal hypotrophy (birth weight of < 10th percentile). RESULTS: The duration of pregnancy was 34.5 and 35 weeks in Groups I and II, respectively. Mean birth weight in Groups I and II was 2608.64 g and 2046.30 g, respectively (p = 0.002). Mean weight percentile in Groups I and II was 36.57 and 2.91, respectively (p < 0.000). Proteinuria in the first half of pregnancy occurred in 16 and 14 patients from Groups I and II, respectively, and increased in the second half of pregnancy in 6 and 6 patients from Groups I and II, respectively. Patients from Group II were more prone to urinary tract infections (0.43 vs. 0.79; p = 0.02). CONCLUSIONS: Current diagnostic criteria for preeclampsia are insufficient in case of pregnant women after kidney transplant. General criteria should be applied with special care in women with chronic kidney disease or in patients with systemic lupus erythematosus. As a predictive factor of neonatal morbidity, intrauterine growth restriction seems to be more valuable than typical markers of kidney function.

Menopause in women with chronic immunosuppressive treatment - how to help those patients.

Women after organ transplantation with chronic immunosuppressive therapy or after bone marrow transplantation without such therapy are a growing group of patients. Although their problems in the peri- and postmenopausal period are the same as in healthy women, due to the primary disease and treatment applied they represent a huge challenge from the point of view of their hormonal treatment of menopause. Transplanted women have no particular contraindications for hormonal therapy use. General contraindications, however, such as arterial hypertension, thrombosis in medical history, diabetes, endometriosis, myomas, or active neoplastic disease, have a higher incidence in this group of patients than in healthy women, which significantly influences the possibility of using hormonal therapy. On the other hand, taking into consideration the predisposition for premature menopause in this group, in combination with chronic immunosuppression, it predisposes these patients for higher cardiovascular disease incidence and bone density loss, so hormonal therapy would be highly advisable. Therapy management in transplanted patients requires special care and close monitoring of the transplanted organ. Saving lives with organ transplantation is one of the greatest achievements of contemporary medicine. For long-term improvement of their quality of life, emphasis should be put on regular diagnostic examinations, early detection of abnormalities, and introduction of effective treatment.

Activity of Proteolytic Enzymes and Level of Cystatin C in the Peripartum Period.

Objectives. The aim of the study was to evaluate the activity of cathepsin B, collagenases, trypsin, and plasmin and concentration of cystatin C in serum of healthy pregnant women in peripartum period. Study Design. The study group included 45 women in uncomplicated pregnancies. Blood samples were collected in four time points. Enzyme activity was measured by spectrofluorometric method. The level of cystatin C was measured using immunonephelometric method. Results. Mean activity of cathepsin B and the level of serum cystatin C were significantly higher in the study group. Collagenase activity was significantly lower in the study group than the control group. No differences in collagenase, plasmin, and trypsin activity on each day of the peripartum period were found. Conclusion. High activity of cathepsin B and increased level of cystatin C are typical for women in late pregnancy. Those levels significantly decrease after delivery which can be associated with potential role of those markers in placental separation. The insignificant changes of cystatin C level in the peripartum period seem to exclude the possibility of using cystatin C as a marker for renal insufficiency in the peripartum period but additional research is necessary to investigate the matter further.

Gestational diabetes insipidus. Case Report.

Gestational diabetes insipidus is a very rare complication. However, undiagnosed and untreated may lead to serious complications in both mother and fetus. In this study, a case of 34-year-old female patient with diabetes insipidus associated with pregnancy was reported. We discussed process of diagnosis and treatment with particular emphasis on the monitoring of water-electrolyte imbalance during labor.

Non trophoblastic source of human chorionic gonadotropin - problem in diagnostic accuracy.

Human chorionic gonadotropin (hCG) is a polypeptide hormone studied as far as 1912, but researchers has no complete knowledge concerning its biological function. Since 1970' it is known that hCG can be found not only in the urine and serum of pregnant, but in choriocarcinoma and testicular cancer patients. Up-to-date one can distinguish four subtypes of hCG differing in secondary carbohydrate chains configuration as well as it regular and glycosylated forms, but non trophoblastic sources of this hormone, such as pituitary are still not widely known. The article gives an overlook on hCG studies in order to help clinicians in taking wise, evidence based decisions in asymptomatic patients with elevated hCG.

Pregnancy after kidney and liver transplantation: its outcome and effect on the graft, mother, and neonate.

BACKGROUND: The influence of pregnancy on graft function in patients after solid organ transplantation is still uncertain. MATERIAL AND METHODS: Our study is based on a group of 78 cases after liver (LTR) and/or renal transplantation (RTR) with 91 deliveries in the past 12 years in the 1st Department of Obstetrics and Gynecology, Warsaw Medical University. We compared duration of pregnancy, mode of delivery, weight of neonates, and graft function. RESULTS: Rate of preterm delivery was very high (74% RTR and 43% LTR). The average duration of pregnancy was shorter in the RTR than in the LTR group (34.7 vs. 36.8 p<0.001) with a high rate of cesarean sections (81.4% in RTR and 68.1% in LTR). Birth weight in LTR (2898 g) was higher than in RTR (2248 g) (p<0.0001). Currently, 29 RTR and 38 LTR have preserved graft function. Thus, graft survival in the study group is longer than in the general RTR or LTR population. CONCLUSIONS: Pregnancy after kidney or liver transplantation does not seem to increase the risk of graft loss, but is associated with a higher risk of maternal and fetal complications. In our data these complications occur more often in the RTR group.

The role of vitamin D in impaired fertility treatment.

Vitamin D is currently in the scope of research in many fields of medicine. Despite that its influence on health remains uncertain. This paper presents the review of the publications concerning the role of calciferol in reproduction processes and its significance in infertility therapy covering topics of polycystic ovary syndrome, endometriosis infertility, myoma infertility, male infertility, premature ovary failure and in vitro fertilization techniques. The results of latest research articles in those fields has been discussed and summarized. The deficiency of vitamin defined as the concentration of 25-hydroxycalciferol <20 ng/ml is frequently noted in patients of fertility clinics. Serum vitamin D concentration in healthy women is higher comparing to PCOS patients. The supplementation with vitamin D should be applied in the schemes of PCOS treatment both due to an improved insulin resistance and the results of infertility treatment. The explanation of vitamin D activity mechanism in patients with PCOS requires further research. Vitamin D have direct effect on AMH production, and thus increase longer maintenance of ovarian reserve in the patients with its higher concentration. The occurrence of uterine myomas in the group with vitamin D deficiency was evaluated as much higher comparing to controls. On the other hand it is supposed that high concentration of calciferol may be related to an impaired elimination of endometrial cells passing to peritoneal cavity via ovarian reflux causing endometriosis. In male infertility both low (<20 ng/ml) and high (>50 ng/ml) concentration of vitamin D in serum negatively affects spermatozoa number per ml of semen, their progressive movement and morphology. Significant differences as a response on ovulation stimulation, number and quality of embryos depending on vitamin D concentration were not observed in none of the analyzed papers concerning the role of vitamin D in in vitro fertilization (IVF). Better results in patients without calciferol insufficiency are explained by reports about high concentration of vitamin D and its metabolites in human in decidua collected in the 1st trimester of pregnancy which suggests its contribution in proper implantation and local immunological preference of the embryo. It is accepted that the treatment requires vitamin D concentration below 20 ng/ml (up to 50 nmol/l), especially in obese women, these with insulin resistance and small ovarian reserve and in men with oligo- and asthenozoospermia.

Pregnancy risk in female kidney and liver recipients: a retrospective comparative study.

OBJECTIVE: To determine and compare maternal, neonatal and graft outcomes in pregnant women after kidney or liver transplantation, who had delivered from 1 January 2005 to 1 February 2010. METHODS: A retrospective, single-center study provided in Warsaw, Poland. RESULTS: Complete data were collected in 38 deliveries in 37 women. Preexisting hypertension was present in 15 of 19 (79%) pregnant kidney recipients and in 2 of 19 (10.5%) women after liver transplantation (p < 0.000). The incidence of preeclampsia was also more often in pregnant kidney recipients (p = 0.04). Mean gestational age at labor was lower in the kidney group (34.9 ± 3.56 vs. 37.5 ± 1.62, p = 0.000). A similar relation was observed in the frequency of preterm deliveries before 37 weeks of gestation (42% vs. 11%, respectively, p = 0.02) and neonates small for gestational age (47% vs. 11%, respectively, p = 0.008). Cesarean sections were performed in approximately 79% (15/19) and 95% (18/19) liver and kidney posttransplant pregnancies, respectively. Four of 38 infants presented structural malformations. CONCLUSIONS: Pregnancies after kidney transplantation are complicated with a higher prevalence of prematurity and worse neonatal prognosis, which depends mainly on the underlying condition.

The comparison of two different embryo culture methods in the course of in vitro fertilization program.

The objective of the study was to compare two different embryo culture methods in the course of in vitro fertilization program by means of fertilization rate, embryo development, total time and cost. 98 patients undergoing assisted reproduction procedures due to infertility were analyzed. The inclusion criteria for the study: first IVF-ET program, at least 10 MII oocytes, no indications for ICSI. Oocytes were divided into two study groups: group A- open culture (oocytes placed in four-well dishes together, then inseminated and cultured in successive wells) and group B - a closed culture (oocytes placed in microdroplets, each embryo cultured separately). The fertilization rate was assessed around 18 hours from insemination. The embryos were classified into four classes. The best embryos were chosen for transfer. In the group A the fertilization rate obtained was lower than in group B (68% vs. 78%, respectively). The microdroplet culture required more time on the insemination day and on the second day of culture, while the four-well dish method required more time on the first day of culture and on the day of transfer. On analyzing the total cost of the above procedures (MI medium and oil costs) it occurred that the microdroplet culture was more expensive than the four-well dish method (due to the intake of paraffin oil). However, the difference was of no practical importance. In the conclusion, microdroplet culture gives a higher fertilization rate than four-well dish culture, probably due to a homogenous sperm distribution. Despite the differences in time outside the incubator and laboratory expenses (which are after all insignificant) microdroplet culture allows a better control over the embryo development. The embryos of best developmental potential can therefore be chosen for ET.

[The preliminary evaluation of surgical treatment of pelvic organ prolapse with polypropylene mesh by double transobturator approch technique (double TOT)]. / Wstepna ocena wyników operacyjnego leczenia zaburzen statyki narzadu plciowego z uzyciem siatki polipropylenowej z podwójnym dostepem przez otwory zaslonione (Double Transobturator Approach).

OBJECTIVES: The aim of this study was to evaluate preliminary results of a new, simple surgical technique with the use of polypropylene mesh (double TOT) used for the treatment of cystocele associated / not associated with urinary incontinence in females. MATERIAL AND METHODS: 19 women, aged 49-76, BMI 24-40, with cystocele associated or not with urinary incontinence, were operated on at the 1st Department of Obstetrics and Gynaecology in Warsaw, using double TOT technique. In this technique, described by Theobald, the trapezoidal polypropylene four-arm vaginal mesh is inserted through the obturator foramens from the outside to the inside and is positioned without tension under the urethra. RESULTS: 9 patients qualified for the operation were grade III in POPQA, 5--grade IV, 4--grade II and one patient grade I. 16 women had additional operations performed beside double TOT. The duration of operations varied from 30 to 135 minutes. No intra-operative complications were observed. There were no complications in short 6 weeks follow-up. CONCLUSIONS: Double Transobturator technique is simple, easy to learn, safe and, at the same time, efficient surgical procedure for the treatment of pelvic organ prolapse and female urinary stress incontinence. The results of longer follow-up on a larger group of operated patients will be more accurate.

[Heterotopic pregnancy]. / Ciaza heterotopowa.

We report a case of combined intrauterine and extrauterine (tubal) pregnancy in 24-year-old woman. The patient was admitted to the Clinic at 9 weeks gestational age with abdominal pain lasting 2 hours. Pelvic ultrasonography revealed alive 9-week intrauterine pregnancy, free fluid in the peritoneal cavity and left adnexal mass. A left salpingectomy was performed, with removal of ruptured ampulla with ectopic pregnancy, without complications. The intrauterine pregnancy proceeded uneventfully to 39 weeks, was terminated by cesarean section, resulting in birth of a healthy female infant of 3630 grams.
