RESUMO

PURPOSE: Patient blood management [PBM] has been acknowledged and successfully introduced in a wide range of medical specialities, where blood transfusions are an important issue, including anaesthesiology, orthopaedic surgery, cardiac surgery, or traumatology. Although pregnancy and obstetrics have been recognized as a major field of potential haemorrhage and necessity of blood transfusions, there is still little awareness among obstetricians regarding the importance of PBM in this area. This review, therefore, summarizes the importance of PBM in obstetrics and the current evidence on this topic. METHOD: We review the current literature and summarize the current evidence of PBM in pregnant women and postpartum with a focus on postpartum haemorrhage (PPH) using PubMed as literature source. The literature was reviewed and analysed and conclusions were made by the Swiss PBM in obstetrics working group of experts in a consensus meeting. RESULTS: PBM comprises a series of measures to maintain an adequate haemoglobin level, improve haemostasis and reduce bleeding, aiming to improve patient outcomes. Despite the fact that the WHO has recommended PBM early 2010, the majority of hospitals are in need of guidelines to apply PBM in daily practice. PBM demonstrated a reduction in morbidity, mortality, and costs for patients undergoing surgery or medical interventions with a high bleeding potential. All pregnant women have a significant risk for PPH. Risk factors do exist; however, 60% of women who experience PPH do not have a pre-existing risk factor. Patient blood management in obstetrics must, therefore, not only be focused on women with identified risk factor for PPH, but on all pregnant women. Due to the risk of PPH, which is inherent to every pregnancy, PBM is of particular importance in obstetrics. Although so far, there is no clear guideline how to implement PBM in obstetrics, there are some simple, effective measures to reduce anaemia and the necessity of transfusions in women giving birth and thereby improving clinical outcome and avoiding complications. CONCLUSION: PBM in obstetrics is based on three main pillars: diagnostic and/or therapeutic interventions during pregnancy, during delivery and in the postpartum phase. These three main pillars should be kept in mind by all professionals taking care of pregnant women, including obstetricians, general practitioners, midwifes, and anaesthesiologists, to improve pregnancy outcome and optimize resources.

RESUMO

OBJECTIVE: To compare the detection rates of vaginal-perineal cultures for group B streptococci (GBS) with the standard vaginal and rectal cultures and evaluate the diagnostic yield of vaginal-perineal vs. rectal swabs for extended spectrum ß-lactamase producing Enterobacterales (ESBL-E) during the third trimester of pregnancy. STUDY DESIGN: Vagino-perineal and rectal swabs were collected cross-sectionally from pregnant women between 35-37 weeks gestation and tested for the presence of GBS and ESBL-E. Accuracy of the vagino-perineal swab was compared to the combined vagino-perineal/rectal swab. Risk factors for ESBL carriage were examined. Degrees of pain, discomfort and stress related to the rectal swab were analyzed on visual analogue scales. RESULTS: 48 out of 250 participants (19.2%) were GBS positive. The vagino-perineal swab was positive in 44 of 48 women (91.7%) yielding a negative predictive value of 98.1%. Agreement (kappa) between the two methods was 0.95. Six out of 190 women with additional ESBL-E screening (3.2%) tested positive by rectal swab. Of these, only two had also a positive vagino-perineal swab. The rectal swab caused overall little subjective discomfort, pain or stress, as indicated by low scores indicated on the visual scales. CONCLUSIONS: The GBS detection rate of the vagino-perineal swab was lower compared to the reference standard. However, agreement between the two screening methods was high and there were no cases of GBS neonatal sepsis in the recruited population, supporting this less invasive screening strategy. In contrast, the vaginal-perineal swab was inferior to the rectal swab for detecting ESBL-E, indicating that this less invasive method for detecting antibiotic resistant bacteria that may be potentially transferred to the neonate during labor and delivery would be inappropriate for ESBL-E screening in pregnant women. The low ESBL-E carriage rate among pregnant women likely reflects the prevalence in the general population.

RESUMO

Although an increased risk of pre-eclampsia in pregnancies conceived after infertility treatment has been reported, it remains unknown whether preconceptional minimalisation of known risk factors would help in preventing pre-eclamsia. Obesity and preconceptional blood pressure are discussed as major risks for the development of pre-eclampsia and low doses of aspirins, folic acid, statins and metformin are discussed as potential preventive treatments to decrease the risk of pre-eclampsia. In the present review we discuss whether present-day reproductive medicine could progress towards complication-free pregnancy.

RESUMO

AIMS OF THE STUDY: Combination antiretroviral therapy (cART) has reduced mother-to-child transmissions (MTCT) and improved the prognosis of HIV-infected newborns. However, drug resistance mutations (DRM) in HIV-infected children, either transmitted by MTCT (HIV-tDRM) or selected by suboptimal adherence and drug levels (HIV-sDRM), remain a concern. We sought to determine the rate of HIV-tDRM and HIV-sDRM in MTCT pairs in Switzerland. METHODS: We performed a retrospective analysis of prospectively collected clinical data and available stored samples from MTCT pairs participating in the Swiss Mother-Child HIV (MoCHIV) cohort. RESULTS: We identified 22 HIV-infected mother-child pairs with delivery between 1989 and 2009 who had 15 years of follow-up (33% white ethnicity). Twenty-one women (96%) were treatment-naïve before pregnancy, 8 (36%) had an unknown HIV status and delivered vaginally, 2 were diagnosed but not treated, and 11 (50%) received antiretrovirals during pregnancy or at delivery, of whom only 6 cases (27%) had cART. HIV subtypes were concordant in all mother-child pairs (subtype B 13/22 [59%]). Using stored plasma (n = 66) and mononuclear cell (n = 43) samples from the children, HIV-tDRM (M184V) was identified in 1 of 22 (4.5%) mothers (1/11 treated, 9%) and was followed by HIV-sDRM at 10 months of age. HIV-sDRM (M184V 23%; K103N 4.5%; D67N 13.6%) occurred in 16/22 (73%) after 4 years, half of whom were treatment naïve. HIV-sDRM were associated with a lower CD4 T-cell nadir (p <0.05) and tended to have higher viral loads and more frequent cART changes. CONCLUSIONS: HIV-tDRM were low in this Swiss MoCHIV cohort, making them a minor yet preventable complication of prenatal HIV care, whereas HIV-sDRM are a significant challenge in paediatric HIV care.

RESUMO

BACKGROUND: Data on the prevalence of persistent symptoms in the first year after preeclampsia are limited. Furthermore, possible risk factors for these sequelae are poorly defined. We investigated kidney function, blood pressure, proteinuria and urine sediment in women with preeclampsia 6 months after delivery with secondary analysis for possible associated clinical characteristics. METHODS: From January 2007 to July 2014 all women with preeclampsia and 6-months follow up at the University Hospital Basel were analyzed. Preeclampsia was defined as new onset of hypertension (≥140/90 mmHg) and either proteinuria or signs of end-organ dysfunction. Hypertension was defined as a blood pressure ≥ 140/90 mmHg or the use of antihypertensive medication. Proteinuria was defined as a protein-to-creatinine ratio in a spot urine > 11 mg/mmol. Urine sediment was evaluated by a nephrologist. Secondary analyses were performed to investigate for possible parameters associated with persistent symptoms after preeclampsia. RESULTS: Two hundred two women were included into the analysis. At a mean time of follow up of 172 days (+/- 39.6) after delivery, mean blood pressure was 124/76 mmHg (+/- 14/11, range 116-182/63-110) and the mean serum-creatinine was 61.8 µmol/l (33-105 µmol/l) (normal < 110 µmol/l). Mean estimated glomerular filtration rate using CKD-EPI was 110.7 mml/min/1.73m2 (range 59.7-142.4 mml/min/1.73m2) (normal > 60 mml/min/1.73m2). 20.3% (41/202) had a blood pressure of 140/90 mmHg or higher (mean 143/89 mmHg) or were receiving antihypertensive medication (5.5%, 11/202). Proteinuria was present in 33.1% (66/199) (mean 27.5 mg/mmol). Proteinuria and hypertension was present in 8% (16/199). No active urine sediment (e.g. signs of glomerulonephritis) was observed. Age and gestational diabetes were associated with persistent proteinuria and severe preeclampsia with eGFR decline of ≥ 10 ml/min/1.73m2. CONCLUSION: Hypertension and proteinuria are common after 6 months underlining the importance of close follow up to identify those women who need further care.

RESUMO

BACKGROUND: In order to improve the safety for drugs in pregnancy and lactation, data on the clinical practice must be collected and validated. METHODS: Data on the medications routinely used were requested from the university hospitals for obstetrics and the non-university perinatal centres in Switzerland and recommendations and guidelines of scientific societies for the various fields of application were sought. RESULTS: Part I: For during pregnancy and the peripartal period respectively, 69 and 21 different active constituents of medications were identified from at least 4 centres. For during pregnancy, the active constituents used in most of the centres are nifedipine, iron i. v. and oral, labetalol and magnesium sulphate, amoxicillin with clavulanic acid, paracetamol, dalteparine, metoclopramide as well as atosiban and hexoprenaline; for during the peripartal period betamethasone, misoprostol, oxytocin, clindamycin as well as fibrinogen, sulprostone and tranexamic acid were most frequently cited. Recommendations of various scientific societies were found primarily for pregnancy-specific fields of application. CONCLUSION: The same active constituents of medications are consistently used in Swiss perinatal centres for the main indications in pregnant women. Despite the existing experience and available evidence, they are mainly used off-label. Official authorisations for frequently or consistently used active ingredients should be granted.

RESUMO

A team of experts from the fields of gynaecology and obstetrics, diabetology, internal medicine, paediatrics and midwifery from Germany, Austria and Switzerland produced a new version of the existing S3 guideline on gestational diabetes. It replaces the recommendations of the German Association for Gynaecology and Obstetrics and the German Diabetes Association on the diagnosis and treatment of gestational diabetes from 2011 and is valid for the three German-speaking countries. The primary aim of the guideline is to improve and standardise the prevention, screening, diagnosis, treatment and follow-up of gestational diabetes through evidence-based recommendations for the outpatient and inpatient area. A large number of new studies and data published in the last few years required a comprehensive revision of the 2011 guideline. The new aspects include early screening of pregnant women with a high risk for diabetes or gestational diabetes, the validity of two-stage screening in the third trimester by means of the 50-g challenge test, as specified in the maternity guidelines, use of metformin instead of or in addition to insulin in gestational diabetes, and birth planning with GDM and/or macrosomia. The recommendations are based on the evidence from the literature, which was selected through a systematic external literature search. All recommendations had to pass through a consensus process. The present text corresponds to the practice guideline on gestational diabetes, which is an action-oriented short version of the evidence-based S3 guideline that can be viewed on the internet.

RESUMO

AIMS OF THE STUDY: Fetal abnormalities found on ultrasonography lead to a variety of diagnostic procedures, including a panel of serologies to detect possible maternal STORCH infections encompassing syphilis, Toxoplasma gondii, rubella, cytomegalovirus, herpes simplex, and others (human immunodeficiency virus, hepatitis B and C, parvovirus B19, enterovirus, varicella zoster, and Leptospira interrogans). The value of indiscriminate testing for infections upon the detection of fetal ultrasound abnormalities has been questioned. The aim of this study was to review the ultrasonographic abnormalities leading to maternal STORCH panels at the obstetrics department of a university hospital. METHODS: Laboratory results of all maternal STORCH tests requested after the detection of ultrasonographic abnormalities during a 5-year period (2008-2012) were analysed. The main ultrasound findings possibly caused by congenital infection were noted, and the outcomes of confirmed maternal and fetal infections were studied. RESULTS: In our study period, 392 maternal STORCH tests were performed because of fetal ultrasound abnormalities. The most common findings leading to STORCH testing were intrauterine growth restriction (30.4%) including microcephaly (1.5%), polyhydramnios (14.8%), and intrauterine fetal demise (13.3%). Maternal STORCH infections were found in 3.4% of growth-restricted fetuses, 5.2% of polyhydramnios, and 1.9% of intrauterine fetal demise. The leading aetiologies were cytomegalovirus and parvovirus B19. All seven congenital infections displayed multiple ultrasonographic abnormalities. CONCLUSION: Ultrasonographic findings associated with fetal infection are neither sensitive nor specific. Testing for STORCH infections should take into account exposure history, clinical signs and symptoms, obstetric history, and fetal ultrasound findings, but with special attention paid to cytomegalovirus and parvovirus B19.

RESUMO

BACKGROUND: Alloimmunization against human platelet antigens (HPAs) during pregnancy is rare but can lead to severe bleeding disorders, such as fetal and neonatal alloimmune thrombocytopenia. STUDY DESIGN AND METHODS: In a cohort of 241 uncomplicated pregnancies, we investigated the immunogenicity of HPA mismatches and correlated HLA sensitization with HPA antibody formation. HPA antibodies were measured with a Luminex-based multiplex assay. RESULTS: HPA mismatches were observed in 109 of 241 pregnancies (45%), but child-specific HPA antibodies were only found in two of 109 cases (2%), indicating a low immunogenicity. Only nine of 241 women (4%) had detectable HPA antibodies. HLA sensitization was identified as a strong and independent predictor for HPA antibody formation (hazard ratio, 10.2; 95% confidence interval, 1.8-193; p = 0.006), whereas the number of pregnancies was not. CONCLUSION: Our observational data indicated a low immunogenicity of HPA and suggest that a broader immune response-inferred by HLA sensitization-is probably associated with HPA antibody induction.

RESUMO

Inherited paternal HLA antigens from the semi-allogeneic fetus may trigger maternal immune responses during pregnancy, leading to the production of child-specific HLA antibodies. The prevalence of these HLA antibodies increases with the number of successful pregnancies. In the present study, we investigated the effect of a single prior miscarriage on HLA antibody formation during a subsequent successful pregnancy. Women with a successful pregnancy with one or more prior miscarriages (n = 229) and women with a successful pregnancy without a prior miscarriage (n = 58), and their children were HLA typed. HLA antibody analyses were performed in these women to identify whether HLA antibodies were formed against mismatched HLA class-I antigens of the last child. The percentage of immunogenic antigens was significantly lower after a single successful pregnancy that was preceded by a single miscarriage (n = 18 women) compared to a successful pregnancy that was preceded by a first successful pregnancy (n = 62 women). Thus, our data suggest that a previous miscarriage has a different impact on child-specific HLA antibody formation during a subsequent successful pregnancy than a previous successful pregnancy. The lower immunogenicity in these women cannot be explained by reduced numbers of immunogenic B-cell and T-cell epitopes. In conclusion, our observations indicate that increasing gravidity is not related to an increased prevalence of HLA antibodies in a single successful pregnancy that was preceded by a single prior miscarriage.

RESUMO

The concept that HLA antibodies recognize epitopes is leading to new approaches of HLA matching at the epitope level. HLA-DQ plays an important role and many studies have identified structurally defined DQ epitopes specifically recognized by antibodies; they have been recorded in the International HLA Epitope Registry http://www.epregistry.com.br but the list is still incomplete. Pregnancy offers an attractive model to study antibody responses to HLA epitopes. The current analysis was done on 42 DQ-reactive post-pregnancy sera tested in binding assays with a panel of DQ heterodimers. The reactivity of 29 sera corresponded fully to the presence of antibody-verified DQA and DQB epitopes recorded in the Registry. Analysis of the remaining 13 sera led to the identification of additional antibody-defined DQB and DQA epitopes. We have designed the first version of an eplet map for DQ alleles which includes antibody-defined DQA and DQB epitopes and shows sequence positions with polymorphic residues which can be used in HLA epitology studies to identify new antibody-defined DQ epitopes.

RESUMO

PURPOSE: Postpartum haemorrhage (PPH) represents a leading cause of maternal morbidity and mortality. Giving oxytocin after birth reduces the risk for PPH. It has never been tested whether different methods of oxytocin administration affect the maternal outcome. This study aims to compare the infusion versus the bolus application of oxytocin after singleton vaginal delivery. METHODS: This retrospective monocentre study compares the incidence of clinically relevant postpartum complications in women receiving 5 IE of oxytocin as a bolus or as a 100 ml-infusion over 5 min, given immediately after birth. Included were women delivering singletons vaginally at term. We used propensity score weighting to compare outcomes between women receiving bolus and infusion and to minimize the selection bias in this retrospective cohort. RESULTS: 1765 patients were included. Patient characteristics were balanced. We found no significant differences for the combined overall postpartum adverse outcome (the incidence of PPH, manual removal of the placenta and/or curettage). For the single outcomes, we observed a significantly higher frequency of manual removal of the placenta (Odds ratio 1.47, 95 % CI 1.02-2.13) and a slightly higher but clinically not relevant estimated blood loss (Relative effect 1.05, 95 % CI 1.01-1.10) in the infusion group. CONCLUSION: The data show a tendency towards more complications in the infusion group. It is related to a more frequent need for manual removal of the placenta.

RESUMO

This report describes a HLAMatchmaker-based antibody analysis of post-pregnancy sera with antibodies against child-specific HLA-DR epitopes. These sera were reactive in IgG-binding assays with single allele bead (SAB) panels on a Luminex platform. The antibody specificity analysis focused on DRB epitopes that have been recorded in the International HLA Epitope Registry (http://www.epregistry.com.br) as experimentally verified with informative antibodies but we also considered other eplets that predict potential epitopes. The SAB panel has in several instances two or more alleles corresponding to the same serologically defined DR antigen and we selected six sera were with different reactivity patterns with DR1, DR4, DR13 and/or DR52 alleles. We demonstrate here how amino acid differences between these alleles can provide useful information in the determination of new epitope specificities of antibodies in these sera. Eight newly antibody-verified epitopes were identified including three that correspond to eplets paired with self-residue configurations. Epitope specificity information appears to be useful in the prediction of mismatch acceptability of non-SAB alleles within serological DR antigen groups.

RESUMO

OBJECTIVE: Threatened preterm labor (tPTL) is a complication of pregnancy. Identification of women and clinical definition differs between countries. This study investigated differences in tPTL and effectiveness of vaginal progesterone to prevent preterm birth (PTB) between two countries. METHODS: Secondary analysis of a randomized controlled trial (RCT) from Argentina and Switzerland comparing vaginal progesterone to placebo in women with tPTL (n = 379). Cox proportional hazards analysis was performed to compare placebo groups of both countries and to compare progesterone to placebo within each country. We adjusted for baseline differences. Iatrogenic onset of labor or pregnancy beyond gestational age of interest was censored. RESULTS: Swiss and Argentinian women were different on baseline. Risks for delivery <14 days and PTB < 34 and < 37 weeks were increased in Argentina compared to Switzerland, HR 3.3 (95% CI 0.62-18), 54 (95% CI 5.1-569) and 3.1 (95% CI 1.1-8.4). In Switzerland, progesterone increased the risk for delivery <14 days [HR 4.4 (95% CI 1.3-15.7)] and PTB <37 weeks [HR 2.5 (95% CI 1.4-4.8)], in Argentina there was no such effect. CONCLUSION: In women with tPTL, the effect of progesterone may vary due to population differences. Differences in populations should be considered in multicenter RCTs.
