RESUMO

INTRODUCTION: Placental dysfunction is one of the most common causes of Intrauterine Fetal Demise (IUFD). Due to its characteristics, the placenta may be the target of molecular research aimed to investigate potential causes of IUFD. In the literature, there are no studies on human placentas that have investigated possible associations between somatic mutations and the occurrence of IUFD. The aim of this study was to identify the presence of gene mutations in placental tissues in a series of cases of IUFD and to evaluate potential correlations with placental microscopic findings. MATERIALS AND METHODS: Thirty-seven samples of formalin-fixed and paraffin-embedded placental tissues were retrospectively selected from pregnancies ending in IUFD between 23rd to 40th week. Six control placentas of physiological pregnancies were included as controls. After sampling, made according to standardized protocol and conventional histopathological examination, placental tissues were subjected to DNA extraction and sequencing by means of Next Generation Sequencing with a 56-gene panel. RESULTS: The most frequent mutation observed in 32/37 IUFD cases (86.5%) and absent in any of the 6 control placentas was in c-KIT gene, which is implicated in placental tissue differentiation. However, no significant correlation was found between the presence of individual gene mutations and placental histopatological findings. DISCUSSION: As the present study found an elevated frequency of c-KIT mutation in IUFD, it further supports the hypothesis that c-KIT is involved in abnormal tissue differentiation leading to altered placental vascularization and function.

RESUMO

PURPOSE: Pregnant women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection have a higher risk of hospitalization, admission to intensive care unit (ICU) and invasive ventilation, and of acute respiratory distress syndrome (ARDS). In case of ARDS and critical severe coronavirus disease 2019 (COVID-19), the use of extracorporeal membrane oxygenation (ECMO) is recommended when other respiratory support strategies (oxygen insufflation, non-invasive ventilation [NIV], invasive ventilation through an endotracheal tube) are insufficient. However, available data on ECMO in pregnant and postpartum women with critical COVID-19 are very limited. METHODS: A case series of three critically ill pregnant women who required ECMO support for COVID-19 in pregnancy and/or in the postpartum period. RESULTS: The first patient tested positive for COVID-19 during the second trimester, she developed ARDS and required ECMO for 38 days. She was discharged in good general conditions and a cesarean-section [CS] at term was performed for obstetric indication. The second patient developed COVID-19-related ARDS at 28 weeks of gestation. During ECMO, she experienced a precipitous vaginal delivery at 31 weeks and 6 days of gestation. She was discharged 1 month later in good general conditions. The third patient, an obese 43-year-old woman, tested positive at 38 weeks and 2 days of gestation. Because of the worsening of clinical condition, a CS was performed, and she underwent ECMO. 143 days after the CS, she died because of sepsis and multiple organ failure (MOF). Thrombosis, hemorrhage and infections were the main complications among our patients. Neonatal outcomes have been positive. CONCLUSION: ECMO should be considered a life-saving therapy for pregnant women with severe COVID-19.

RESUMO

Undifferentiated connective tissue disease (UCTD) is characterized by signs and symptoms suggestive of a connective tissue disease (CTD), but not fulfilling criteria for a specific CTD. Although UCTD is probably the most common rheumatic disease diagnosed in pregnant women, data about disease course during pregnancy and perinatal outcomes are very limited. Compared to other CTDs, UCTD seems to have milder clinical manifestations in pregnancy. Its natural history is related to disease activity at conception. In fact, if the disease is in a state of remission or minimal activity at conception, pregnancy outcomes are generally good. On the contrary, patients who become pregnant in a moment of high disease activity and/or who have multiple antibodies positivity show an increased risk of disease flares, evolution to a definite CTD and obstetric complications, such as fetal growth restriction, preeclampsia and preterm birth. Therefore, a preconception assessment is essential in women with UCTD to evaluate maternal and fetal risks, to initiate interventions to optimize disease activity, and to adjust medications to those that are least harmful to the fetus. The aim of the present study was to review the available literature about pregnancy course, maternal and fetal outcomes and therapeutic approaches of pregnant women with UCTD.

RESUMO

PURPOSE: The aim of the study is to compare maternal hemodynamic adaptations in gestational diabetes (GDM) versus healthy pregnancies. METHODS: A prospective case-control study was conducted, comparing 69 singleton pregnancies with GDM and 128 controls, recruited between September 2018 and April 2019 in Maternal-Fetal Medicine Unit, Careggi University Hospital, Florence, Italy. Hemodynamic assessment by UltraSonic Cardiac Output Monitor (USCOM) was performed in both groups in four gestational age intervals: 17-20 weeks (only in early GDM cases), 26-30 weeks, 32-35 weeks and 36-39 weeks. We evaluated six hemodynamic parameters comparing GDM cases versus controls: cardiac output (CO), cardiac index (CI), stroke volume (SV), total vascular resistance (TVR), inotropy index (INO) and potential to kinetic energy ratio (PKR). RESULTS: GDM group had significantly lower values of CO and SV than controls from the early third trimester (26-30 weeks) until term (p < 0.001). CI is significantly lower in GDM women already at the first evaluation (p = 0.002), whereas TVR and PKR were significantly higher in GDM (p < 0.001). GDM women showed also lower INO values than controls in all assessments. CONCLUSIONS: A hemodynamic maternal maladaptation to pregnancy can be detected in GDM women. The effect of hyperglycemia on vascular system or a poor pre-pregnancy cardiovascular (CV) reserve could explain this hemodynamic maladaptation. The abnormal CV response to pregnancy in GDM women may reveal a predisposition to develop CV disease later in life and might help in identifying patients who need a CV follow-up.

RESUMO

BACKGROUND: Randomized trials reported no difference whether induction or expectant management is performed in non-diabetic women with large for gestational age babies but no tool has been validated for the prediction of high risk cases. AIM: Assessing the performance of different growth curves in the prediction of complications. METHODS: Data from 1066 consecutive non-diabetic women who delivered babies ≥4000 g were collected. Logistic regression analysis was used to analyze the impact of the maternal variables on: instrumental delivery, shoulder dystocia (SD), perineal tears, cesarean section (CS), and postpartum hemorrhage. Intergrowth21 curves and customized Gardosi's curves were compared in terms of prediction of adverse outcomes. FINDINGS: Induction of labor was performed in 23.1% cases. The rate of CS was 17%. Hemorrhage, fetal distress, and SD occurred in 2%, 1.3%, and 2.7% of cases, respectively. Induction was significantly associated with instrumental delivery (p < .001), CS (p = .001), third and fourth degree perineal tears (p = .031), and post-partum hemorrhage (p = .02). The cutoff of 90th percentile according to Intergrowth21 did not show significant performance in predicting CS, while the same cutoff according to the Gardosi curves showed an OR 1.92 (CI 1.30-2.84) (p = .0009). DISCUSSION: Gardosi curves showed a better performance in predicting the risk of CS versus Intergrowth curves. Induction is significantly associated with adverse outcome in non-diabetic women with LGA babies.

RESUMO

Objective: Maternal characteristics and OGTT values of pregnancies complicated by gestational diabetes mellitus (GDM) were evaluated according to treatment strategies. The goal was to identify different maternal phenotypes in order to predict the appropriate treatment strategy. Methods: We conducted a retrospective study among 1,974 pregnant women followed up for GDM in a tertiary referral hospital for high-risk pregnancies (Careggi University Hospital, Florence, Italy) from 2013 to 2018. We compared nutritional therapy (NT) alone (n = 962) versus NT and insulin analogues (n = 1,012) group. Then, we focused on different insulin analogues groups: long acting (D), rapid acting (R), both D and R. We compared maternal characteristics of the three groups, detecting which factors may predict the use of rapid or long-acting insulin analogue alone versus combined therapy. Results: Among women included in the analysis, 51.3% of them needed insulin therapy for glycemic control: 61.8% D, 28.3% combined D and R, and 9.9% R alone. Age >35 years, pre-pregnancy BMI >30, family history of diabetes, previous GDM, altered fasting plasma glucose (FPG), hypothyroidism, and assisted reproductive technologies (ART) were identified as maternal variables significantly associated with the need of insulin therapy. Altered 1-h and 2-h glucose plasma glucose level at OGTT, age >35 years, and previous GDM were found as independent predicting factors for the use of combined therapy with rapid and long acting analogues for glycemic control. On the contrary, pre-pregnancy BMI <25 and normal fasting plasma glucose values at OGTT were found to be significantly associated to the use of rapid insulin analogue only. Conclusion: A number of maternal and metabolic variables may be identified at the diagnosis of GDM, in order to identify different GDM phenotypes requiring a personalized treatment for glycemic control.

RESUMO

Women with criteria and non-criteria obstetric antiphospholipid syndrome (APS) carry an increased risk of pregnancy complications, including fetal growth restriction (FGR). The management of obstetric APS traditionally involves clinicians, obstetricians and gynaecologists; however, the most appropriate prophylactic treatment strategy for FGR prevention in APS is still debated. We performed a systematic review and network meta-analysis (NetMA) to summarize current evidence on pharmacological treatments for the prevention of FGR in APS. We searched PubMed and Embase from inception until July 2020, for randomized controlled trials and prospective studies on pregnant women with criteria or non-criteria obstetric APS. NetMA using a frequentist framework were conducted for the primary outcome (FGR) and for secondary outcomes (fetal or neonatal death and preterm birth). Adverse events were narratively summarised. Out of 1124 citations, we included eight studies on 395 pregnant patients with obstetric APS treated with low-dose aspirin (LDA) + unfractionated heparin (UFH) (n = 132 patients), LDA (n = 115), LDA + low molecular weight heparin (n = 100), LDA + corticosteroids (n = 29), LDA + UFH + intravenous immunoglobulin (n = 7), or untreated (n = 12). No difference among treatments emerged in terms of FGR prevention, but estimates were largely imprecise, and most studies were at high/unclear risk of bias. An increased risk of fetal or neonatal death was found for LDA monotherapy as compared to LDA + heparin, and for no treatment as compared to LDA + corticosteroids. The risk of preterm birth was higher for LDA + UFH + IVIg as compared to LDA or LDA + heparin, and for LDA + corticosteroids as compared to LDA or LDA + LMWH. No treatment was associated with an increased risk of bleeding, thrombocytopenia or osteopenia.

RESUMO

In recent years, a growing interest has arisen regarding the possible relationship between adverse pregnancy outcomes (APOs) and inadequate maternal hemodynamic adaptations to the pregnancy. A possible association between "placental syndromes," such as preeclampsia (PE) and fetal growth restriction (FGR), and subsequent maternal cardiovascular diseases (CVD) later in life has been reported. The two subtypes of FGR show different pathogenetic and clinical features. Defective placentation, due to a poor trophoblastic invasion of the maternal spiral arteries, is believed to play a central role in the pathogenesis of early-onset PE and FGR. Since placental functioning is dependent on the maternal cardiovascular system, a pre-existent or subsequent cardiovascular impairment may play a key role in the pathogenesis of early-onset FGR. Late FGR does not seem to be determined by a primary abnormal placentation in the first trimester. The pathological pathway of late-onset FGR may be due to a primary maternal cardiovascular maladaptation: CV system shows a flat profile and remains similar to those of non-pregnant women. Since the second trimester, when the placenta is already developed and increases its functional request, a hypovolemic state could lead to placental hypoperfusion and to an altered maturation of the placental villous tree and therefore to an altered fetal growth. Thus, this review focalizes on the possible relationship between maternal cardiac function and placentation in the development of both early and late-onset FGR. A better understanding of maternal hemodynamics in pregnancies complicated by FGR could bring various benefits in clinical practice, improving screening and therapeutic tools.

RESUMO

OBJECTIVE: To evaluate the efficacy and safety of intravenous immunoglobulin (IVIg) in secondary prevention of pregnancy complications for patients with obstetric antiphospholipid syndrome (APS) and history of stillbirth. METHODS: We described three cases of obstetric APS patients with history of stillbirth treated with IVIg in four pregnancies. In addition, we conducted a systematic literature review on the use of IVIg in obstetric APS with history of stillbirth. RESULTS: Three patients with obstetric APS and history of stillbirth were treated with prophylactic IVIg, in addition to standard treatment (hydroxychloroquine, low-dose aspirin, low molecular weight heparin, and prednisone), in four pregnancies (three singleton and one twin). All pregnancies resulted in live healthy newborns. Long-term follow-up re-evaluations (24-53 months) did not shown any sign or symptom of active systemic disease, and the children were healthy. The systematic literature review retrieved only three cases of use of IVIg in obstetric APS patients with history of stillbirth. All three cases resulted in live healthy newborns. Only in one case, mild thrombocytopenia occurred during treatment, although this event was unlikely to be related to IVIg. CONCLUSION: Our experience suggests that IVIg as secondary prevention of APS-related stillbirth is associated with good pregnancy and long-term outcomes, with no relevant safety concerns. However, the literature evidence on this topic is limited to few isolated cases, and further studies are needed to clarify which obstetric APS patients may benefit the most from IVIg.

RESUMO

Cardiac arrest in pregnancy is a rare event due to different cause. When it occurs after spinal anesthesia a cause that can explain this event is the Bezold-Jarish Reflex (BJR). A cardiac arrest occurs in a pregnant women after spinal anesthesia admistered for urgent caesarean section. During this event perimortem caesarean delivery (PMCD) is the rapid surgical way that can improve maternal and fetal outcomes. In this situation, it is very important to have a multidisciplinary team of midwives, obstetricians, anesthetists, neonatologists, intensivists that is able to perform perimortem caesarean delivery according to the guidelines.

RESUMO

BACKGROUND: The aim of the study is to compare the obstetric outcome between single pregnancies obtained by medically-assisted procreation using oocyte donors (MAP-E) versus homologous gametes (MAP-O) and single spontaneous conception pregnancies (SC). METHODS: This is a retrospective case-control study on pregnancy outcome of consecutive singleton live birth pregnancies from MAP-E between January 2011 and August 2017 referred to Careggi University Hospital, Florence. The control group includes singleton pregnancies from MAP-O and pregnancies from spontaneous conceptions in the same period. The pregnancy outcomes considered were: postpartum hemorrhage (PPH), cesarean section (CS), gestational diabetes mellitus (GDM), hypertensive disorders including preeclampsia (HDP), preterm birth ≤34 weeks (PTB), and small-for-gestational-age (SGA) fetuses. RESULTS: The study group included 290 MAP-E pregnancies that were compared with 290 MAP-O and 870 singleton spontaneous conception pregnancies. The three groups did not show significant differences in maternal traits except for mean age (43.4±2.9 vs. 37.7±2.4 vs. 33.6±5.5, P<0.001), including a higher percentage of patients over 45 years (41.3% vs. 5% vs. 0.8%, P<0.001) and higher incidence of obesity (7.2% vs. 1.7%, P=0.02) in MAP-E than in MAP-O. The risk of HDP is increased in singleton pregnancies by oocyte donation with a significantly increased risk if compared to MAP-O (12% vs. 1%, P<0.001, OR=12.6). The risk of PPH in singleton pregnancies from oocyte donation is higher than in MAP-O (22% vs. 9% P<0.0001, OR=2.87). When we considered severe PPH (blood loss >1000 mL) the risk for MAP-E was higher if compared to MAP-O (OR=2.1, P=0.2) and mostly to SC (OR=14, P<0.005). Compared to SC, MAP-E pregnancies showed increased OR for all the outcomes: CS (78% vs. 30.8%, P<0.001, OR=7.91); GDM (26.1% vs. 10.8%, P<0.001, OR=2.92); HDP (12% vs. 2.2%, P<0.001, OR=5.99); PPH (22% vs. 8.5%, P<0.0001, OR=3.0); SGA (16% vs. 11%, P<0.05, OR=1.16); PTB ≤34 weeks (9.4% vs. 1%, P<0.001, OR=7.94). CONCLUSIONS: Most women who undergo MAP-E are in advanced age, representing a high-risk population for obstetric complications, like HPD and PPH, which stands as the main worldwide cause of maternal mortality.

RESUMO

INTRODUCTION: Systemic lupus erythematosus (SLE) commonly affects women of childbearing age. Hypertension, antiphospholipid syndrome, and lupus nephritis are risk factors for adverse maternal/fetal outcome. The aim of this retrospective cohort study is to compare pregnancy outcomes in patients with and without SLE nephritis, using a multidisciplinary approach and a broad prophylaxis protocol. MATERIALS AND METHODS: Data were collected from 86 pregnancies complicated by SLE. Twenty-seven women with nephropathy before pregnancy stated as the study group and 59 formed the control group. Each group received a prophylactic treatment based on their clinical characteristics. Results were expressed as mean ± SD, percentage and χ2-test (significant values when p < .05). RESULTS: The prophylactic treatment (60.4% of the patients) significantly controlled the complications related to some risk factors, such as antiphospholipid antibodies (aPL) and nephritis. Preeclampsia occurred in 14.8% of patients. Patients with pregestational hypertension showed a 2.75 odds ratio of adverse events when compared to the group without chronic hypertension. The presence of proteinuria was associated with a risk of preeclampsia 2.45 times greater, as well as serum creatinine >1.2 mg/dL, which was related to a risk 1.25 times higher than the risk observed in patients with serum creatinine <1.2 mg/dL. A 6-month inactive disease was associated with a better outcome. A value of Estimated Glomerular Filtration Rate (eGFR) < 90 mL/min/1.73 m2 resulted in a 18.73 times greater risk of preeclampsia, intrauterine growth restriction (IUGR), and preterm delivery. DISCUSSION: A multidisciplinary approach in a tertiary care center and a broad prophylactic treatment protocol to patients affected by SLE and complicated by nephritis may definitively foster a successful pregnancy.

RESUMO

PROBLEM: The aim of this study was to investigate the prevalence of human leukocyte antigens (HLA) DQ2 and DQ8 haplotypes, two common polymorphisms associate with celiac disease (CD), in women with previous stillbirth, but not affected by CD. METHOD OF STUDY: Women with history of unexplained term stillbirth referred to our Center for High-Risk Pregnancies for a preconception counseling, and women with previous uncomplicated pregnancies, were enrolled as cases and controls. Celiac women were excluded from the study. Genetic tests for HLA DQ2/DQ8 were performed, and patients' data were compared. RESULTS: The population included 56 women with a previous term stillbirth and 379 women with history of uncomplicated pregnancies. The prevalence of HLA-DQ2 or DQ8 positivity was significantly higher in cases than in controls (50% vs 29.5%) (P = 0.0031). Women with HLA DQ8 genotype have a significantly higher risk of stillbirth (OR: 2.84 CI: 1.1840-6.817) and in case of DQ2 genotype the OR for stillbirth was even higher (OR: 4.46 CI: 2.408-8.270). In the stillbirth group, SGA neonates were significantly more frequent in those with HLA-DQ2/DQ8 haplotypes than in those resulted negative to genetic testing (85.7% vs 42 .8%, P = 0.004). CONCLUSION: In women with history of term stillbirth, a significantly higher prevalence of HLA DQ2/DQ8 haplotypes has been found compared to women with previous uneventful pregnancies. In addition, HLA DQ2/DQ8 positivity was significantly associated with suboptimal fetal growth in intrauterine fetal death cases, as shown by an increased prevalence of SGA babies.

RESUMO

BACKGROUND: Late onset intrauterine growth restriction (IUGR) represents one of the main causes of perinatal morbidity/mortality. No guidelines are available on labor induction in IUGRs, even if delivery at 37/38 weeks is suggested. This study aims to assess maternal-fetal variables related to adverse outcome in labor induction for late IUGR. METHODS: One hundred cases of induction for late IUGR were retrospectively revised on fetal weight, MCA, UA, CPR and uterine artery (utA) Doppler, oligohydramnios, Bishop score, start of induction, augmentation. The variables were matched with the following adverse outcomes: CS or vacuum extractor delivery (IVD); NICU admission; low Apgar score; UA pH < 7.10. RESULTS: Regular vaginal delivery occurred in 65% of cases; the rate of CS and IVD was 32% and 5%. UA, MCA and CPR abnormalities were all significantly related to a higher risk of CS. Bishop score < 3 and start of induction by oxitocin resulted statistically associated to CS, while prostaglandins were related to vaginal delivery. No augmentation and oxitocin in labor were positively related to vaginal delivery. Maternal morbidity and Bishop score < 3 showed a significant association with NICU admission. DISCUSSION: Doppler velocimetry of UA, MCA and CPR are useful tools for the identification and management of the late term IUGRs.

RESUMO

OBJECTIVE: To investigate the proportion of stillbirths at term associated with abnormal growth using customized birth weight percentiles and to compare histological placental findings both in underweight stillborn fetuses and in live births. METHODS: A retrospective case-control study of 150 singleton term stillbirths. The livebirth control groups included 586 cases of low-risk pregnancies and 153 late fetal growth restriction fetuses. Stillbirths and livebirths from low-risk pregnancies were classified using customized standards for fetal weight at birth, as adequate for gestational age (AGA; 10-90th percentile), small (SGA; <10th percentile) or large for gestational age (LGA; >90th percentile). Placental characteristics in stillbirth were compared with those from livebirths using four categories: inflammation, disruptive, obstructive and adaptive lesions. RESULTS: There was a higher rate of SGA (26% vs 6%, p<0.001) and LGA fetuses (10.6% vs 5.6%, p<0.05) in the stillbirth group. Among stillbirth fetuses, almost half of the SGA were very low birthweight (≤3°percentile) (12% vs 0.3%, p<0.001). The disruptive (7.3% vs 0.17%;p<0.001), obstructive (54.6% vs 7.5%;p<0.001) and adaptive (46.6% vs 35.8%;p<0.001) findings were significantly more common in than in livebirth-low risk. Placental characteristics of AGA and SGA stillbirth were compared with those of AGA and FGR livebirth. In stillbirths-SGA we found a higher number of disruptive (12.8% vs 0%; p<0.001), obstructive (58.9% vs 23.5%;p<0.001) and adaptive lesions (56.4% vs 49%; p 0.47) than in livebirth-FGR. CONCLUSION: The assessment of fetal weight with customized curves can identify fetuses which have not reached their genetically determined growth potential and are therefore at risk for adverse outcomes. Placental evaluation in stillbirths can reveal chronic histological signs that might be useful to clinical assessment, especially in underweight fetuses.

RESUMO

OBJECTIVE: To evaluate outcome in the pregnancy following a stillbirth (SB) by a placental vascular disorders. STUDY DESIGN: A prospective, observational, multicenter study was conducted in woman with a history of stillbirth (> 22 weeks) between 2005 and June 2013, in 3 Italian University Hospitals. Causes of SB were previously identified after extensive investigations. Pregnant women were enrolled within the first trimester. The main outcome was "adverse neonatal outcome", including perinatal death, fetal growth restriction, early preterm birth <33+6 weeks, hypoxic-ischemic encephalopathy, intracranial hemorrhage or respiratory distress. RESULTS: Out of 364 index pregnancies, 320 women (87.9%) had a subsequent pregnancy during the study period. Forty-seven had an early pregnancy loss. Out of 273 babies, 67 (24.5%) had an adverse perinatal outcome, including 1 SB and 1 early neonatal death (3.7/1000). Women who had a SB related to placental vascular disorders (39.6%), were at higher risk of an adverse neonatal outcome compared with women whose SB was unexplained or resulted from other causes (Adj. OR = 2.1, 95%CI: 1.2-3.8). Moreover, also obesity independently predicts an adverse perinatal outcome (Adj OR = 2.1, 95%CI: 1.1-4.3). CONCLUSION: When previous SB is related to placental vascular disorders there is a high risk for adverse neonatal outcomes in the subsequent pregnancy. Maternal obesity is an additional risk factor.

RESUMO

BACKGROUND: The aim of the study was to assess the outcome of pregnancies achieved by OD in vitro fertilization compared with those obtained by autologous IVF. METHODS: This retrospective cohort study includes 136 consecutive patients who were referred to our centre between 2009 and 2011. According to the mode of conception, they were divided into two groups, whose pregnancy outcomes were analyzed by χ2 Test for unpaired data. RESULTS: Pregnancy-induced hypertension, cesarean section, complications after delivery resulted more frequent in pregnancies from donor oocyte IVF. The other outcomes considered were non-significantly different between the two groups. CONCLUSIONS: The risk of developing preeclampsia, cesarean section, and postpartum complications is higher in patients who conceived by donor oocyte IVF than in patients who underwent autologous IVF.

RESUMO

OBJECTIVE: To compare glycemic control, maternal-neonatal outcomes and fetal fat body mass growth of type 1 diabetic pregnant women treated with continuous subcutaneous insulin infusion (CSII) or multiple daily injections (MDI) with the long-acting insulin analogue detemir as basal insulin. METHODS: Retrospective study of 53 women, attending the Unit of Prenatal Medicine of Careggi University Hospital, Florence, from 2009 to 2012: 35 treated with CSII, 18 with MDI-detemir. Each woman performed daily blood glucose self-monitoring, had an individualized nutritional therapy, weekly prenatal visits and ultrasound scans (US) according to the Tuscan guidelines. US were also performed every two weeks from 28 to 38 weeks of gestation to assess fetal fat body mass growth. Student's t-test and Chi-square test were performed to compare the groups' results. RESULTS: No significant differences were observed in metabolic control, in any maternal and neonatal outcome nor fetal fat body mass growth for either group. The MDI group needed higher daily doses of insulin (MDI: 1.00 ± 0.32 UI/kg versus CSII: 0.75 ± 0.29 UI/kg, p = 0.007) to reach results comparable to the CSII group. CONCLUSIONS: MDI therapy with detemir is a safe and effective alternative, with a good benefit-cost ratio compared to insulin pumps.
