Abstract
OBJECTIVES In this study, we aimed to compare the maternal and neonatal outcomes in pregnant women diagnosed with idiopathic thrombocytopenic purpura (ITP) in our clinic between different platelet groups. METHODS This study was designed retrospectively. A total of 62 pregnant women with ITP were included in the study. Demographic and clinical data for all cases were evaluated. Perinatal outcomes were evaluated according to platelet counts. RESULTS The median age of the patients participating in the study was 27, and their ages ranged from 21 to 44. ITP was diagnosed before pregnancy in 32.3 % (n=20) of the patients and during pregnancy in 67.7 % (n=42). The average platelet counts of the patients during the first trimester and birth were 104.8/μL (15-168) and 84/μL (16-235), respectively. The average platelet count of newborns is 242/μL. The most common (74.2 %) ITP treatment method is the combination of steroids and IVIG. The platelet count of 80.6 % of newborns is above 151/μL. There was no statistical difference between the results of both mothers and fetuses when the groups were categorized according to maternal platelet levels. CONCLUSIONS In this study, no difference was observed in maternal and neonatal morbidity and mortality rates, despite the different platelet counts of patients with ITP. The cooperation of the hematology, gynecology, obstetrics, and neonatology departments is responsible for this.

Aslan MT, İnce Z, Bilgin L, Kunt İşgüder Ç, Çoban A. Is it possible to predict morbidities in neonates born to mothers with immune thrombocytopenic purpura?: A retrospective cross-sectional study. Medicine (Baltimore) 2024; 103:e38587. [PMID: 38905433 PMCID: PMC11191858 DOI: 10.1097/md.0000000000038587] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 05/23/2024] [Indexed: 06/23/2024] Open
Abstract
Immune thrombocytopenic purpura (ITP) comprises ~1% to 4% of thrombocytopenia cases during pregnancy. Factors predicting neonatal thrombocytopenia and associated morbidities due to maternal ITP are unclear. The present study aimed to assess the neonatal outcomes of pregnant women with ITP. Fifty-five pregnant women with ITP and their babies, born between January/2013 and April/2021, were retrospectively reviewed. Maternal and neonatal thrombocytopenia cases other than ITP were excluded from the study. Physical examination, blood count, and cranial/abdominal ultrasonography findings of the newborns were recorded. Neonatal thrombocytopenia was defined as a platelet count < 150 × 109/L. Relationship between neonatal thrombocytopenia and maternal factors was investigated. Thrombocytopenia was detected in 17/55 babies (30.9%), and 8/17 (47.1%) had symptoms of bleeding, all but one being mild bleeding. There was a significant correlation between neonatal platelet counts of < 100 × 109/L and maternal splenectomy history. Incidence of moderate and severe thrombocytopenia was higher (statistically insignificant) in neonates of mothers with ITP. No significant correlation was determined between maternal and neonatal platelet counts. There was a weak insignificant correlation between platelet counts of neonates of mothers with or without thrombocytopenia. A significant correlation was found between the presence of splenectomy before delivery in the mother and a platelet count of < 100 × 109/L in the neonate. Moderate and severe thrombocytopenia was higher in neonates of mothers diagnosed with ITP before pregnancy and needed treatment during pregnancy and/or delivery, but the difference was insignificant. Close follow-up of babies born to mothers with ITP after birth is crucial since there is no significant prediction criterion for developing neonatal thrombocytopenia and associated morbidities.

Abstract
The risk of immune thrombocytopenia (ITP) worsening during pregnancy and neonatal ITP (NITP) have never been prospectively studied. We included 180 pregnant and 168 nonpregnant women with ITP in a prospective, multicenter, observational cohort study. A total of 131 pregnant women with ITP were matched to 131 nonpregnant women with ITP by history of splenectomy, ITP status (no response, response, complete response), and duration. Groups were followed for 15 months. The primary outcome was the first occurrence of ITP worsening defined by a composite end point including bleeding events and/or severe thrombocytopenia (<30 × 109/L) and/or ITP treatment modification. We also studied the recurrence of ITP worsening and the incidence of NITP and risk factors. The first occurrence of ITP worsening did not differ between pregnant and nonpregnant women with ITP (53.4 per 100 person-years [95% confidence interval {CI}, 40.8-69.9] vs 37.1 [95% CI, 27.5-50.0]; hazard ratio {HR}, 1.35 [95% CI, 0.89-2.03], P = .16). Pregnant women with ITP were more likely to have recurrence of severe thrombocytopenia and treatment modification (HR, 2.71 [95% CI, 1.41-5.23], P = .003; HR, 2.01 [95% CI, 1.14-3.57], P = .017, respectively). However, recurrence of severe bleeding events was not different between groups (P = .4). Nineteen (14%) neonates showed NITP <50 × 109/L. By multivariable analysis, NITP was associated with a previous offspring with NITP and maternal platelet count <50 × 109/L within 3 months before delivery (adjusted odds ratio, 5.55 [95% CI, 1.72-17.89], P = .004 and 4.07 [95% CI, 1.41-11.73], P = .009). To conclude, women with ITP do not increase their risk of severe bleeding during pregnancy. NITP is associated with NITP history and the severity of maternal ITP during pregnancy. These results will be useful for counseling women with ITP.

Abstract
AIM Thrombocytopenia is an autoimmune disorder characterized by reduced platelet counts. Neonatal thrombocytopenia incidence has been linked with immune thrombocytopenic purpura in mothers during pregnancy, possibly because antiplatelet antibodies can cross the placental barrier. To date, no study has attempted to evaluate the actual prevalence of neonatal thrombocytopenia in infants born to mothers with immune thrombocytopenic purpura. In this meta-analysis of the available literature, we attempt to fill this gap. We want to evaluate the overall prevalence of neonatal thrombocytopenia, its severity, and the incidence of hemorrhage in infants with thrombocytopenia born from mothers with immune thrombocytopenic purpura. METHODS Adhering to PRISMA guidelines, we systematically scanned four academic databases including EMBASE, CENTRAL, Scopus, and MEDLINE to identify relevant literature. We performed a meta-analysis to summarize thrombocytopenia incidence rate and severity in newborn infants of mothers with immune thrombocytopenic purpura. RESULTS We identified 21 eligible studies involving 1951 mothers and 1844 neonates. Meta-analysis showed high prevalence for neonatal thrombocytopenia (24%). Within these, severe cases were the most prevalent (41.2%), followed by moderate (37.7%) and mild (17.6%) cases. Hemorrhage was only reported in 4.1% of the observed neonatal thrombocytopenia cases. CONCLUSION This review provides preliminary evidence that neonatal thrombocytopenia incidence is high in infants born to mothers with immune thrombocytopenic purpura. This study further reports that the largest proportion of these cases are severe.

Abstract
Introduction Immune thrombocytopenia (ITP) complicates 1-2 cases/10,000 pregnancies in India. Management of these patients is a challenge as it is associated with potential risks of maternal bleeding episodes and neonatal alloimmune thrombocytopenia (NAITP). Objective To study the maternal and fetal/neonatal outcome of pregnancy in Indian patients with ITP and identify the risk factors for NAITP. Materials and Methods In this retrospective study, all ITP patients with pregnancy who were diagnosed and treated at our center over 8 years (August 2010- August 2018) were evaluated for their hematological, obstetrical, and fetal outcomes. Results Twenty-nine pregnancies in 27 ITP patients were studied. The mean interval between the diagnosis of ITP and each pregnancy was 29 ± 14.9 months. The mean baseline platelet count was 0.18 ± 0.05 X 109/L. Twenty-seven (93.1%) cases were treated with oral prednisolone. Twenty deliveries (69.0%) were vaginal and 9 (31.0%) deliveries were by cesarean section. There were no major bleeding episodes during pregnancy or delivery.The mean neonatal platelet count was 1.23 ± 0.58 × 109/L at birth. NAITP was seen in 3 (3.5%) neonates. No bleeds or intracranial hemorrhages were observed. Only maternal platelet count < 50 X 109/L at delivery showed a statistical correlation with NAITP (p = 0.022). There was no positive correlation between NAITP and the duration of maternal ITP, the timing of ITP onset, or type of treatment. Conclusion Successful outcome of pregnancies in ITP patients is possible, and the risk of maternal bleeding and NAITP is low.

Abstract
OBJECTIVE To quantify the incidence of severe autoimmune thrombocytopenia (ITP) in pregnancy in the UK, determine current treatment strategies, and establish maternal and neonatal morbidity and mortality associated with severe ITP in pregnancy. DESIGN A prospective national cohort study. SETTING UK. POPULATION Women with severe ITP, defined as platelets <50 × 109 /L in pregnancy or antenatal treatment of isolated low platelets. METHODS Data collected via the UK Obstetric Surveillance System (UKOSS) between 1 June 2013 and 31 January 2015 from all UK consultant-led obstetric units. MAIN OUTCOME MEASURE Incidence of severe ITP in pregnancy. RESULTS The estimated incidence of severe ITP in pregnancy is 0.83 per 10 000 maternities (95% CI 0.68-1.00). A total of 22 pregnant women (21%) did not receive any antenatal therapy, and 85 pregnant women (79%) received therapy. There was no difference between asymptomatic treated and untreated cohorts in severity of disease or outcome. Postpartum haemorrhage (51%) and severe postpartum haemorrhage (21%) was reported more frequently than the rate reported in the general pregnant population (5-10%). No neonates required treatment for thrombocytopenia and there were no cases of neonatal intracranial bleeding. CONCLUSIONS Current UK management of severe ITP in pregnancy results in an exceptionally low morbidity and mortality for the neonate. Mothers with ITP remain at increased risk of severe postpartum haemorrhage, and should be delivered at units that have the capacity to manage severe PPH effectively. Whilst balancing the risks for pregnancy from prophylactic antenatal treatment in asymptomatic women against observed low disease morbidity, we may be over treating asymptomatic patients. TWEETABLE ABSTRACT UKOSS study of severe ITP in pregnancy shows exceptionally low neonatal morbidity with current UK management.

Abstract
The aim of this study was to determine the safety and efficacy of recombinant human thrombopoietin (rhTPO) for the management of immune thrombocytopenia (ITP) during pregnancy. Pregnant patients with ITP were enrolled in the study if they had a platelet count less than 30 × 109/L, were experiencing bleeding manifestations, had failed to respond to corticosteroids and/or intravenous immunoglobulin (IVIG), and had developed refractoriness to platelet transfusion. Thirty-one patients received rhTPO at an initial dose of 300 U/kg once daily for 14 days. Twenty-three patients responded (74.2%), including 10 complete responders (>100 × 109/L) and 13 responders (30-100 × 109/L). It appears that rhTPO ameliorated the bleeding symptoms remarkably, even in the nonresponders. rhTPO was well tolerated. Dizziness, fatigue, and pain at an injection site were reported in 1 patient each. No congenital disease or developmental delays were observed in the infants in a median follow-up of 53 (range, 39-68) weeks. In conclusion, rhTPO is a potentially safe and effective treatment choice for patients with ITP during pregnancy. Our work has paved the way for further study on the clinical application of rhTPO and other thrombopoietic agents for the management of ITP during pregnancy. This study is registered at www.clinicaltrials.gov as NCT02391272.

Abstract
OBJECTIVE To examine pregnancy and birth outcomes among women with idiopathic thrombocytopenic purpura (ITP) or chronic ITP (cITP) diagnosed before or during pregnancy. METHODS A linkage of mothers and babies within a large U.S. health insurance database that combines enrollment data, pharmacy claims, and medical claims was carried out to identify pregnancies in women with ITP or cITP. Outcomes included preterm birth, elective and spontaneous loss, and major congenital anomalies. RESULTS Results suggest that women diagnosed with ITP or cITP prior to their estimated date of conception may be at higher risk for stillbirth, fetal loss, and premature delivery. Among 446 pregnancies in women with ITP, 346 resulted in live births. Women with cITP experienced more adverse outcomes than those with a pregnancy-related diagnosis of ITP. Although 7.8% of all live births had major congenital anomalies, the majority were isolated heart defects. Among deliveries in women with cITP, 15.2% of live births were preterm. CONCLUSIONS The results of this study provide further evidence that cause and duration of maternal ITP are important determinants of the outcomes of pregnancy.

Abstract
In women with pre-existing immune thrombocytopenic purpura (ITP), the effect of pregnancy on the course of the disease is poorly known. We performed a dual-centre retrospective cohort study of 118 pregnancies in 82 women with primary ITP. In early pregnancy, the platelet count was <100 × 10(9) /l in 35·6% of pregnancies. During pregnancy the median platelet count nadir was 66 × 10(9) /l (25th-75th percentile: 42-117), with platelet count <30 × 10(9) /l for 26 pregnancies (22%). In 49% of pregnancies, a significant decrease of the platelet count required treatment at least transiently in preparation for delivery. At the time of delivery, the median platelet count was 110 × 10(9) /l (77-155). Compared to before pregnancy, at 3 months post-partum, only 11% of pregnancies [95% confidence interval (95% CI): 6·8-20·2] showed disease worsening. Previous splenectomy was the only factor significantly associated with ITP worsening after pregnancy (53·9% vs. 10·3%, P < 0·001). For 8·3% of the pregnancies (95% CI: 3·8-15·1), neonatal thrombocytopenia required treatment, especially in case of previous maternal splenectomy (adjusted odds ratio 16·7, 95% CI: 2·61-106). The overall risk of exacerbation of ITP and severe thrombocytopenia during pregnancy is acceptable.

Abstract
Thrombocytopenia is a common finding in pregnancy, occurring in approximately 7-10% of pregnancies. It may be a diagnostic and management problem, and has many causes, some of which are specific to pregnancy. Although most cases of thrombocytopenia in pregnancy are mild, and have no adverse outcome for either mother or baby, occasionally a low platelet count may be part of a more complex disorder with significant morbidity and may be life-threatening. Overall, about 75% of cases are due to gestational thrombocytopenia, 15-20% secondary to hypertensive disorders; 3-4% due to an immune process, and the remaining 1-2% made up of rare constitutional thrombocytopenias, infections and malignancies. In this review, a diagnostic approach to investigating thrombocytopenia in pregnancy is presented, together with antenatal, anaesthetic and peri-natal management issues for mother and baby, followed by a detailed discussion on the specific causes of thrombocytopenia and the management options in each case.
