ABSTRACT

OBJECTIVE: To provide national guidelines for the management of women with severe preeclampsia. DESIGN: A consensus committee of 26 experts was formed. A formal conflict of interest (COI) policy was developed at the onset of the process and enforced throughout. The entire guidelines process was conducted independently of any industrial funding. The authors were advised to follow the principles of the Grading of Recommendations Assessment, Development and Evaluation (GRADE®) system to guide assessment of quality of evidence. The potential drawbacks of making strong recommendations in the presence of low-quality evidence were emphasized. METHODS: The last SFAR and CNGOF guidelines on the management of women with severe preeclampsia was published in 2009. The literature is now sufficient for an update. The aim of this expert panel guidelines is to evaluate the impact of different aspects of the management of women with severe preeclampsia on maternal and neonatal morbidities separately. The experts studied questions within 7 domains. Each question was formulated according to the PICO (Patients Intervention Comparison Outcome) model and the evidence profiles were produced. An extensive literature review and recommendations were carried out and analyzed according to the GRADE® methodology. RESULTS: The SFAR/CNGOF experts panel provided 25 recommendations: 8 have a high level of evidence (GRADE 1±), 9 have a moderate level of evidence (GRADE 2±), and for 7 recommendations, the GRADE method could not be applied, resulting in expert opinions. No recommendation was provided for 3 questions. After one scoring round, strong agreement was reached between the experts for all the recommendations. CONCLUSIONS: There was strong agreement among experts who made 25 recommendations to improve practices for the management of women with severe preeclampsia.

ABSTRACT

Between 2013 and 2015, cardiovascular diseases became one of the two leading causes of maternal mortality, with 36 deaths (13.7% of maternal deaths). The overall maternal mortality ratio for cardiovascular diseases is 1.5 per 100,000 live births, stable compared to the 2010-2012 period. The etiologies in order of decreasing frequency are: pre-existing cardiomyopathies (n=10), aortic dissections (n=9), peripartum cardiomyopathies (n=6), myocardial infarction (n=4), valvular cardiopathies (n=4). Non-optimal care occurred in 72% of cases, increasing since the previous triennium (50%). Similarly, there is a significant increase in the proportion of preventable deaths (possibly or probably) from 35% to 66%. In women with known cardiovascular disease, the lack of multidisciplinary prepregnancy assessment and pregnancy follow-up is most frequent. In patients with unknown cardiovascular disease, the lack of diagnosis of a cardiac event is the most common failure. Cardiovascular conditions or cardiovascular risk factors should be investigated in early pregnancy in order to monitor and refer women to appropriate maternity hospitals. Recent dyspnea, worsening at the end of pregnancy and postpartum, should suggest a cardiac complication. In presence of chest pain, aortic dissection should be considered with the same degree of emergency as myocardial infarction or pulmonary embolism. Cardiac ultrasonography, chest CT, Nt-proBNP and troponin should be considered in case of chest pain or recent dyspnea. Women with cardiac symptoms should be referred to an emergency department (not necessarily to the local maternity) for a complete cardiovascular check-up.

ABSTRACT

OBJECTIVE: Because of graft shortages, an experimental programme of organ donation after Maastricht 3-type circulatory death (M3) has been proposed by the French organ procurement organization (Agence de la biomedicine: ABM). The aim of the study was to estimate how many potential patients were eligible for an M3-type organ donation, amongst deceased patients who have had life-support withdrawn. PATIENTS AND METHODS: We conducted a retrospective study looking at the notes of deceased patients in a French general intensive care unit (ICU), where organ donation is arranged in DBD donors. RESULTS: Over the year 2013, 1475 patients were admitted in ICU and 215 died. One hundred and one patients were brain-injured and 26 of them died following a decision to withdrawn life-support and without contraindication to organ donation. Among them, 2 patients (8%) met the criteria for the French M3-type organ donation protocol. A 12.5% increase in organ donation activity of our team and five organ transplantations could have been considered. CONCLUSION: If M3 organ donation is considered, a significant increase in transplantation would be expected.

ABSTRACT

A 34-year-old multiparous woman with a breech presentation, intrauterine growth restriction and premature rupture of membranes was transferred to our referral unit at 33 weeks of gestation. She was diagnosed with Alagille syndrome soon after birth because of cholestasis and pruritus. Her condition was later complicated by esophageal varices, treated with propranolol, thrombocytopenia, and insulin-dependent diabetes. She had characteristic facies, posterior embryotoxon, "butterfly" vertebrae but had no cardiac or renal abnormalities. Due to the early onset of spontaneous labor, emergency cesarean section under general anesthesia was performed 48 h after admission. This is the first case describing anesthetic care during delivery in a patient with Alagille syndrome. We discuss the anesthetic implications of the syndrome, emphasizing problems associated with portal hypertension and cholestasis, thrombocytopenia and cardiac abnormalities such as pulmonary artery stenosis.

ABSTRACT

OBJECTIVE: To describe the effects of anaesthetic techniques and agents on the risk of fetal distress during labour pain relief and anaesthesia for caesarean section. STUDY DESIGN: Data on obstetric anaesthesia- and analgesia-induced fetal distress were searched in Medline database using MESH terms: fetal distress, anaesthesia, analgesia, labour, caesarean section, and umbilical artery pH. Trials published in English or French language were selected. RESULTS: Because of their haemodynamic effects, regional anaesthesia and analgesia, especially spinal anaesthesia for Caesarean section, could induce a decrease in umbilical artery pH (UApH). Moreover, intravenous ephedrine, especially when used in large doses can worsen the acidosis. Labour epidural analgesia is associated with a better acid-base balance than systemic analgesia. Experimental studies have demonstrated harmful effects of systemic opioids and hypnotic drugs on UApH and the foetal brain respectively. Clinical implications of these potentially detrimental effects remain to be determined. CONCLUSION: All obstetric anaesthesia and analgesia techniques are associated with a theoretical risk of fetal distress, but given the fact that regional anaesthesia techniques are also associated with well-demonstrated benefits for the mother and the newborn, the latter remain the preferred choice in obstetric practice.

ABSTRACT

Placenta percreta is a severe condition associated with maternal morbidity and mortality even when surgery is performed electively. Arteries ligation, embolisation, medical treatment by methotrexate can be appropriate treatment to avoid catastrophic surgery. The purpose of this report is to present a case where the placenta was left in situ to avoid cystectomy at the time of cesarean section, with subsequent failure of the conservative treatment.

ABSTRACT

Many systemic techniques, so-called "alternatives" to labor epidural analgesia, have been described: they are all poorly effective and some are associated with significant maternal and neonatal side effects. Nonetheless, these techniques can provide good maternal satisfaction. Accordingly, they are indicated when epidural analgesia is contraindicated or unavailable. Administration of systemic opioids mandates maternal respiratory supervision, oxygen supplementation and/or pulse oxymetry. Systemic opioids may also decrease fetal heart rate variability and produce neonatal respiratory depression; naloxone administration to the neonate is therefore widely indicated. Pethidine should be abandoned because it can produce prolonged neonatal respiratory depression. Nalbuphine produces less nausea/vomiting and less long lasting neonatal respiratory depression. Intravenous PCA fentanyl or sufentanil is presently the method of choice during early labor. Alfentanil seems less effective and may produce more neonatal side effects. Intravenous PCA remifentanil is the most effective technique, but safe administration may be problematic during intermittent supervision usually implemented in labour ward. Nitrous oxide 50% provides little pain relief. Nonetheless, it is associated with few side effects, quite good maternal satisfaction and can be quickly implemented during advanced painful labor. It is not recommended to add it to systemic opioid (except under continuous supervision by the anaesthetic team), because of an increased incidence of maternal desaturation. The use of a subanaesthetic concentration of sevoflurane has been described recently; it is more effective than nitrous oxide. However, guidelines for safe implementation in labor ward remain to be determined.

ABSTRACT

Integration of morphological and immunophenotypic data is critical in achieving diagnosis accuracy and minimising interobserver interpretative discrepancies. The aim of this work was to compare the immunophenotype and the morphology of chronic lymphocytic leukaemia and mantle cell lymphoma, to help in the differential diagnosis of CD5 positive monoclonal B cells. Frozen/thawed samples from 91 patients were analysed retrospectively. Fresh samples from 17 mixed/atypical CLL and 13 MCL were tested to corroborate the results. Markers were analysed as percentage (%) of positive B lymphocyte subpopulation, and in terms of median fluorescence intensity (MFI). Matutes's CLL score clearly allowed distinguishing between classical CLL on the one hand, and atypical CLL and MCL on the other hand. The percentage of CD54-positive cells and the median fluorescence intensity of CD20 and CD54 were the only parameters which were significantly higher in MCL than in atypical CLL (P < 0.05), allowing an immunological distinction between these two entities. Nevertheless, due to a quenching problem when using CD20 and CD54 together, and because CD18 showed a statistically different expression between classical and atypical CLL, the combination of CD18/CD54 has been preferred and showed a different pattern in the three entities. Immunophenotyping could be helpful in the differential diagnosis of CD5-positive B cell chronic lymphoproliferative disorders with atypical features that do not fit exactly into any of the morphologic proposed groups.

ABSTRACT

Cord blood (CB) transplantations are associated with low graft-versus-host disease (GVHD). The pathophysiology of GVHD involves interaction and activation of different cell types, as lymphocytes and monocytes, and results in a cascade of cytokine production. After antigen or mitogen stimulation, CB monocytes release lower levels of cytokines than adult blood (AB) monocytes. In this study, the detection of intracellular IL-1 beta and TNF-alpha produced by monocytes was evaluated in response to tuberculin PPD to investigate whether the reduced capacity of CB monocytes to secrete cytokines could be related to an impaired functional activity and to a particular phenotypic profile. Results showed that the percentage of CD64(+)monocytes producing intracellular IL-1 beta and TNF-alpha was significantly lower in CB and that the phenotypic profile of CB monocytes producing these cytokine (CD64(+)CD14(+)) was different to that of AB monocytes (CD64(+)CD14(+), CD64(+)CD33(+) and CD64(+) CD45RO(+)). These results suggest that the lower capacity of CB monocyte populations to produce IL-1 beta and TNF-alpha might be due to a functional immaturity of CB monocytes at the cellular level as reflected by the different phenotypic profile of CB monocytes.

ABSTRACT

BACKGROUND AND OBJECTIVES: Immunophenotyping has become a useful tool for the differential diagnosis of chronic B-cell lymphoproliferative disorders. The aim of this work was to determine reference values of normal B-cell subpopulations. MATERIAL AND METHODS: Blood samples from 38 healthy volunteers were analyzed by multidimensional flow cytometry, using a panel of directly conjugated antibodies. Results were expressed as percent of positive B cells and as median fluorescence intensity, an indirect assessment of the expression level. RESULTS: CD20, CD22, CD24, CD40, CD79a, CD79b, FMC7, CD11a, CD18, CD44 were positive in the whole B cell population, whereas CD10, CD86, CD103, CD154 and FasL were almost absent from the B-lymphocyte population. 75% were IgD positive. The kappa/lambda ratio was 1.5. CD5, CD23, CD25, CD38, CD43, CD54, CD62L, CD80 and CD95 were positive in different B-cell subpopulations. The utility of all these markers in the differential diagnosis of chronic B-cell lymphoproliferative disorders is discussed. CONCLUSION: In order to interpret a pathological immunophenotype, it is necessary to refer to quantitative and qualitative values of normal B-cell subpopulations.

ABSTRACT

A case of CO2 gas embolism occurring during retroperitoneal laparoscopic right radical nephrectomy in a 70-year-old-woman is reported. Patient's outcome was excellent after venous clamping, fluid loading and application of a positive and expiratory pressure. Gas embolism is a well documented complication of laparoscopic surgery, but has been rarely described in retroperitoneal laparoscopy for urologic procedure. The retroperitoneal surgical site, the major surgical procedure with vessel manipulation and the left lateral position seem to be the risk factors for gas embolism in this case.

ABSTRACT

Umbilical cord blood (CB) transplantations are associated with a lower risk of severe graft-versus-host disease (GVHD) compared to BMT. GVHD is an immune reaction that involves interaction between cell surface molecules resulting in cell activation and release of many cytokines. Monocytes are known to be an important source of cell adhesion (CAM) and co-stimulatory molecules which play a crucial role in the efficient activation of T and B cells. We analyzed the phenotype of CB monocytes in the presence or absence of an inflammatory signal (rIFN-gamma) and compared them to adult blood (AB); the expression of HLA-DR and 17 different markers (CD11a, CD11b, CD11c, CD18, CD29, CD40, CD44, CD49a, CD49d, CD49e, CD49f, CD54, CD58, CD62L, CD80, CD86 and CD102) was measured by flow cytometry. Statistical analysis showed that, compared to AB, CB monocytes did not express CD11b, CD11c, CD49d and after stimulation with rIFNgamma, they lost the expression of CD58 and CD102, whereas CD80 and CD86 expression was induced. The analysis of fluorescence intensity (MFI) revealed that CB monocytes expressed some CAM (CD29, CD54, CD102) with a lower intensity than AB monocytes except CD44. In conclusion, absence and reduced expression of some markers argue for a different phenotypic profile of CB monocytes compared to AB monocytes, which might partly contribute to their impaired immune response and to the low incidence of GVHD observed after CB transplantations. However, CB monocytes expressed CD80 and CD86 co-stimulatory molecules, but this expression did not prove a normal co-stimulatory function.

ABSTRACT

Engraftment in relation to infused CD34+ cell number was retrospectively analysed in 66 patients with hematological diseases: non-Hodgkin's lymphoma (n = 33), multiple myeloma (n = 21), acute myelogenous leukemia (n = 7), Hodgkin's disease (n = 4) and myelodysplastic syndrome (n = 1). Progenitor cells were mobilized with rhG-CSF, alone or in association with chemotherapy. The cells were harvested by leukapheresis until at least 2 x 10(6) CD34+/kg body weight were obtained. A total of 194 leukaphereses were performed (median = 3 per patient, range 1-9). A median of 3.40 x 10(8) nucleated cells/kg (range 0.31-27.59) and a median of 7.15 x 10(6) CD34+ cell/kg (range 1.31-115.70) were transplanted. Regardless of transfusional support or patient diagnosis, engraftment was rapid in patients who had received > or = 5 x 10(6) CD34+ cell/kg. In this case, absolute neutrophil blood count > or = 0.5 x 10(9)/l was obtained on day 12 post graft (range 7-19) and platelet count > or = 20 x 10(9)/l was also reached after the same median time interval (range 8-121). From the present results, a minimal threshold of 5 x 10(6) CD34+ cell/kg appears to be suitable for providing rapid and complete hematopoieitc reconstitution in patients exposed to high doses of chemotherapy with or without total body irradiation. Furthermore, administration of rhG-CSF during post-graft period significantly decreased the neutrophil time recovery (P = 0.002) but not that of platelets (P > 0.05).

ABSTRACT

BACKGROUND AND OBJECTIVES: Freezing is a practical approach for cell preservation for retrospective studies. The aim of this work was to check the cryopreservation impact on B cell chronic lymphocytic leukaemia phenotype. MATERIAL AND METHODS: Blood samples from 15 CLL patients were analyzed freshly and after freezing at -196 degrees C, without separation, and thawing. Results were compared by Student's paired t-test. RESULTS: The phenotype of fresh CLL cells was as follows: CD19+, CD5+, faint CD20, CD23+/-, weak CD22 and sIg, CD37+, HLA-DR+, FMC7-. After cryopreservation, the percentage of CD5 and CD23 positive cells decreased, whereas HLA-DR positive cells increased moderately. The CLL Matutes's score was modified in 6 cases out of 15 (40%). CONCLUSION: Cryopreservation modifies B cell chronic lymphocytic leukaemia phenotype, by decreasing CD5 and CD23 expression.

ABSTRACT

BACKGROUND AND AIM: Serum alanine aminotransferase (ALT) level is the most common screening test as part of a routine evaluation of liver damage. In order to determine the factors influencing this liver function test in normal subjects, the relationship between ALT level and gender, age and body mass index (BMI) was studied in a large population of healthy blood donors. METHODS: This population included 9,420 volunteer blood donors (4,488 men and 4,932 women aged from 18 to 70 years) selected on the basis of negative answers to a detailed medical questionnaire including past medical history, drug and alcohol consumption, on the absence of clinical signs of liver disease, on the negativity of serological testing for hepatitis B and C virus and HIV. RESULTS: In the overall population, the mean serum ALT value was 21.8 I.U./L and the mean BMI was 24.4 kg/m2. There was a positive significant correlation between serum ALT level and BMI (Pearson r = 0.54; p < 0.001) and between ALT and age (Pearson r = 0.25; p < 0.001). A major sex-difference in ALT value was observed, the mean ALT value being higher in men than in women (26.8 +/- 13.6 vs. 17.2 +/- 8.1 I.U./L, p < 0.0001). In both sexes, ALT level was significantly correlated with BMI (Pearson r = 0.45 in men and r = 0.37 in women; p < 0.001). In women a consistent rise in BMI and ALT value with increasing age was observed whereas in men BMI and ALT level only increased with age up to the fifth decade. IN CONCLUSION: There was a significant positive correlation between ALT and BMI regardless the gender in a population of healthy volunteer blood donors. Moreover, at the same age and the same BMI, ALT was significantly lower in women than in men suggesting that the normal range for ALT value should be adjusted for gender. So gender and BMI have to be considered in the interpretation of ALT values.

ABSTRACT

Helper T-lymphocyte precursor (HTLp) frequency from 19 allogeneic bone marrow donors was tested to detect weak antigenic differences with the recipient, and then compared to the outcome. HTLp frequency was estimated in limiting dilution cultures, and HLA-DR and CD 80 expression by stimulating cells was measured by flow cytometry. 12/19 patients experienced acute graft-versus-host disease (aGVHD) grade II-IV. A good correlation was found between high pretransplant HTLp frequency and grade II-IV aGVHD (median: 1/55848 PBMNC for II-IV GVHD versus 1/184346 for 0-I GVHD; P = 0.008). Sensitivity was 82%, specificity 63%, negative predictive value 71% and positive predictive value 75%. Long-term survivors also had a lower HTLp median frequency (1/143354) when compared with patients who died as a result of the transplant procedure (1/22100, P < 0.001). No correlation was found between HTLp frequency and HLA-DR or CD80 expression by patient's cells. We conclude that HTLp frequency estimation can predict, although poorly, acute GVHD risk and long-term survival.
