thrombocytopenia in pregnancy

BACKGROUND: Polycythemia is a disorder with several causes and risk factors. The clinical presentation is variable, ranging from asymptomatic newborns to cases with severe physiological changes. The aim of this study was to assess the prevalence, risk factors and predictors of severity of polycythemia in a Portuguese level III Neonatal Intensive Care Unit (NICU). METHODS: Case-control study of all term newborns with the diagnosis of polycythemia admitted to the NICU of the São João Universitary Hospital Center, Porto, Portugal, from January 1, 1999 to December 31, 2019; and who met one of the following inclusion criteria were eligible for the study: 1) Hct>65% or Hb>22 g/dL; and 2) Hb≥21 g/dL with clinical manifestations of polycythemia...

Immune thrombocytopenia (ITP) in pregnancy is challenging for both mother and fetus. Understanding the pathophysiology, treatments, and risks to the mother and fetus leads to proper management resulting in successful pregnancy and delivery in almost all cases.1 ITP in a pregnant woman has many similarities to ITP not in pregnancy although gestational thrombocytopenia can be confused with ITP. However, recognizing differences is instrumental in avoiding bleeding complications and toxicities of treatment. This Nutshell review focuses on the natural history of ITP in pregnancy, its treatment, and dilemmas...

A multigravida in her late 20s was diagnosed with inferior vena cava thrombosis (IVCT) and PE at 26 weeks of pregnancy after a routine prenatal care visit. The patient denied any diseases that could cause IVCT, as well as the presence of any symptoms. Progressive thrombocytopenia was diagnosed in the period until the implantation of the inferior vena cava filter (IVCF). Due to a rupture of foetal membranes and chorioamnionitis, labour was induced at 32 weeks of pregnancy. The IVCF remained in place and anticoagulants were continued through the postpartum period for up to 6 months...

Massive splenomegaly complicating pregnancy is a rare clinical entity that poses special difficulties, such as anemia, thrombocytopenia, ascites, and jaundice. This case report of a pregnant woman with large splenomegaly and pancytopenia highlights the value of prompt diagnosis and effective treatment. Splenomegaly can have a number of causes, including viral infections, hematological problems, portal hypertension, and metabolic abnormalities. A 29-year-old gravida 3 woman at 37 weeks of gestation who had massive splenomegaly was admitted and underwent a cesarean section to avoid complications of splenomegaly...

OBJECTIVE: While thrombosis and pregnancy loss are the best-known clinical features of antiphospholipid syndrome (APS), many patients also exhibit "extra-criteria" manifestations, like thrombocytopenia. The mechanisms that drive APS thrombocytopenia are not completely understood, and no clinical biomarkers are available for predicting antiphospholipid antibody (aPL)-mediated thrombocytopenia. Calprotectin is a heterodimer of S100A8 and S100A9 that is abundant in the neutrophil cytoplasm and released upon proinflammatory neutrophil activation...

Thrombocytopenia (TCP) is the second most common hematological change during pregnancy and is considered as a major source of maternal and neonatal morbidity and mortality. Despite its effects to morbidity and mortality, it is frequently ignored or disregarded, particularly in resource-limited nations. Thus, the purpose of this study was to determine the prevalence of thrombocytopenia and associated factors among pregnant women attending antenatal care at Hiwot Fana Comprehensive Specialized University Hospital, Eastern Ethiopia from June 20 to August 30, 2022...

BACKGROUND: Fetal and neonatal alloimmune thrombocytopenia (FNAIT) ensues from parental incompatibility for platelet alloantigens with maternal sensitization. HPA-1a/1b incompatibility is the most common cause of FNAIT in Caucasians. Placental villitis and lower birthweight in FNAIT suggest anti-HPA-1a may have effects beyond inducing thrombocytopenia. OBJECTIVES: Does FNAIT secondary to anti-HPA-1a result in smaller newborns and, the corollary, does antenatal management of FNAIT increase birthweight? STUDY DESIGN: Birthweights of 270 FNAIT-affected newborns from a randomized clinical trial and a NAITbabies...

Unlike classic APS, CAPS causes multiple microthrombosis due to an increased inflammatory response, known as a "thrombotic storm". CAPS typically develops after infection, trauma, or surgery and begins with the following symptoms: fever, thrombocytopenia, muscle weakness, visual and cognitive disturbances, abdominal pain, renal failure, and disseminated intravascular coagulation. Although the presence of antiphospholipid antibodies in the blood is one of the diagnostic criteria, the level of these antibodies can fluctuate significantly, which complicates the diagnostic process and can lead to erroneous interpretation of rapidly developing symptoms...

BACKGROUND: Hypertensive disorders in pregnancy can cause prenatal placental perfusion with insufficient blood supply to the fetus, resulting in fetal exposure to hypoxia and leading to disturbance of neonatal hematopoietic stem cells. This study aimed to compare the hematological profiles of newborns from mothers with hypertensive disorders and normotensive delivered at the University of Gondar comprehensive specialized hospital. METHODS: A comparative cross-sectional study was conducted from March to May 2022 among 308 newborns from hypertensive and normotensive mothers in equal proportions...

Fetal and neonatal alloimmune thrombocytopenia (FNAIT) is a rare, life-threatening condition causing significant thrombocytopenia and bleeding with the risk of developing intracerebral hemorrhage (ICH). It results from maternal immunizations against fetal platelet antigens. Here, we report a case of a pregnant patient at 30 weeks gestation who presented to the hospital with a low platelet count of 90 th/mm3 and was found to have anti-human platelet antigen (HPA) 1a, 2b antibodies. She was treated with a weekly infusion of IV immunoglobulins...

We report a case of atypical hemolytic uremic syndrome (aHUS) that occurred after childbirth in a patient with a history of numerous recurrent episodes of TMA with nephrotic proteinuria and impaired renal function. At 33 weeks of the first spontaneous pregnancy, proteinuria up to 0.8 g/l was first registered, at 38 weeks she was hospitalized with proteinuria, reaching a maximum of 13 g/l, she was delivered promptly, after which progressive thrombocytopenia was noted over the next few days (up to 44×109 /l) and anemia and severe arterial hypertension, which could not be corrected by several groups of antihypertensive drugs...

BACKGROUND: Platelet-related problems are more frequently discovered in women during pregnancy because screening is carried out as part of the initial clinic examination using automated blood counts. This study was done to find out the frequency and outcomes of pregnant females presenting with thrombocytopenia at a tertiary care hospital. METHODOLOGY: This cross-sectional study was conducted at the Department of Obstetrics and Gynecology, Jinnah Hospital, Lahore, Pakistan, from April 2023 to September 2023...

The "One Health" concept is a universal approach to sustainably balancing and optimizing the health of humans, animals, and ecosystems. This approach is based on the health of humans, domestic and wild animals, and plants in a wider environment in which self-renewable ecosystems exist, with essential characteristics of integration, unifying and holistic perspective. Toxoplasmosis, one of the most common zoonotic infections in both terrestrial and oceanic ecosystems in the world, is an ideal model disease for the "One Health" approach...

Autoimmune hepatitis (AIH) is a rare autoimmune liver disease that mostly affects women in their reproductive years, leading to impaired fertility. Nonetheless, the majority of women with well-controlled AIH have a favorable prognosis for pregnancy. This case report describes a 29-year-old pregnant woman with cirrhosis secondary to AIH who presented with severe thrombocytopenia. Her labs showed a decline in her platelet counts from 28 × 109 /L before pregnancy to 20 × 109 /L during pregnancy...

BACKGROUND: Cavernous haemangiomas are benign vascular tumours that are known to occasionally involve the female genital tract, including the uterus. They are often underdiagnosed during pregnancy, although they can also lead to severe postpartum or antepartum haemorrhage. OBJECTIVES: Describe our case of an uncommon second-trimester pregnancy loss in a woman with a diffuse cavernous haemangioma of the uterus and cervix and review the wider literature. METHODS: The review was conducted using MEDLINE, Scopus and PubMed electronic databases from beginning of the database to May 2023, using the following keywords: arteriovenous malformation; cavernous haemangioma/hemangioma; uterine neoplasms; pregnancy complications; abnormal vaginal bleeding...

Dengue is one of the most prevalent mosquito-borne diseases in today's world, especially in India. It is an important health problem and it is very important to address it promptly. Acquiring dengue during pregnancy can have a considerable influence on the health of the mother and baby. In dengue fever, moderate to severe consequences can occur in the mother. Severe dengue poses additional risks to pregnant women due to the likelihood of sequelae such as severe dengue, preeclampsia, gestational hypertension, anemia, maternal death and hemolysis, organ dysfunction, and even death...

OBJECTIVE: Listeriosis is caused by the bacterium, Listeria monocytogenes, and is a significant health concern because of high hospitalization and mortality rates. This study reports seven cases of pregnancy-associated listeriosis diagnosed with matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) mass spectrometry performed on infection-positive blood culture. METHODS: Blood culture-positive samples of seven patients whose pregnancy was complicated by Listeria infection and treated at Xuanwu Hospital of Capital Medical University between January 2016 and December 2021 were analyzed retrospectively...

Haematinic deficiency is not uncommon in pregnancy. Folate deficiency is more common than B12 deficiency because of the increased uptake of folate in pregnancy, and the fact that B12 stores take much longer to deplete. Described here are five cases of anaemia in pregnancy secondary to severe haematinic deficiency with subsequent management and pregnancy outcomes. In the majority of cases, the women were proteinuric, but systemically well and normotensive. Thrombotic thrombocytopenic purpura and HELLP were both considered, but the identification of very abnormal folate levels of less than 3 μg/L in all and low B12 deficiency in the majority made haematinic deficiency the most likely diagnosis...

Platelet counts reduction occurs throughout pregnancy, with 5-12% of pregnancies being diagnosed with gestational thrombocytopenia (GT), characterized by a decrease in platelet count during pregnancy. However, the underlying biological mechanism behind this altered platelet count phenomenon and GT remains unclear. Here, we utilized sequencing data from non-invasive prenatal test (NIPT) among 100,186 Chinese pregnancies and conducted the hitherto largest-scale genome-wide association studies (GWAS) on platelet counts at five periods of pregnancy (the first, second, and third trimesters, delivery, and the postpartum period), as well as two GT statuses (GT: platelet count < 150 × 109/L and severe GT: platelet count < 100 × 109/L)...

BACKGROUND: Amniotic fluid embolism is an unpredictable and sometimes lethal complication of childbirth. Fibrinogen γ-chain peptide-coated, ADP-encapsulated Liposomes (H12-(ADP)-liposomes), which were developed as a platelet substitute, may be useful to control postpartum hemorrhage with consumptive coagulopathy. OBJECTIVE: This study aimed to establish a hemodynamically stable amniotic fluid embolism animal model and evaluate the efficacy of H12-ADP-liposome infusion in the initial management of postpartum hemorrhage complicated with amniotic fluid embolism-involved coagulopathy...
