preterm haematology

Hannah M Sebitloane, Dhayendre Moodley
HIV is the leading cause of maternal and neonatal morbidity and mortality in resource constrained countries. Highly active antiretroviral treatment (HAART) initiated in pregnancy has now almost eliminated mother to child transmission of the virus, and is beginning to show the desired effect of reducing HIV related maternal mortality. By modulating host immunological responses HAART has the potential to alter infections during pregnancy, in addition to modifying clinical conditions such as preeclampsia. There is increasing evidence of the benefits of HAART given to pregnant women, however there is paucity of data that distinguishes HIV or HAART as the cause or exacerbation of pre-existing medical conditions or conditions specific to pregnancy...

Chronic myeloid leukaemia (CML) is amongst the most common haematological malignancies encountered in adults. The younger age of onset and increased incidence of CML in Indians leads to higher chances of encountering it in pregnancy. Pregnancy in CML is a complex situation as first line therapy with tyrosine kinase inhibitors (TKI), is fraught with multiple fetal safety issues. The fetal aspects have been elucidated in literature, but there is scarcity of information on the obstetric outcome per se in presence of CML, excluding the influence of TKI...

A preterm neonate at 29-week gestational age was born with intrauterine growth restriction, severe pancytopaenia and gross skeletal dysplasia. Antenatal screening bloods, TORCH/parvovirus tests and karyotype were unremarkable. Postnatally, he had normal microarray comparative genomic hybridization and serum B12/folate levels, and human immunodeficiency virus and cytomegalovirus polymerase chain reaction and antoimmune screening were negative. Targeted gene testing for Shwachman-Diamond syndrome (SDS) revealed the pathognomic mutation (c...

Mycoplasma suis causes infectious anaemia in pigs (IAP), which can manifest in various degrees of severity depending on the virulence and the host's susceptibility. As M. suis cannot be cultured in vitro experimental infections of splenectomised animals play an essential role for pathogenesis research. The aim of the present study was to characterise the course of experimental infection using the highly virulent and red blood cell (RBC-) invasive M. suis strain KI3806, to compare the experimental course in splenectomised and non-splenectomised pigs and to correlate clinical and haematological parameters with M...

Systemic neonatal infection is a serious complication in preterm and term infants and is defined as a complex clinical syndrome caused by bacteria, fungi and virus. Sepsis remains among the leading causes of death in both developed and underdeveloped countries above all in the neonatal period. Earlier diagnosis may offer the ability to initiate treatment to prevent adverse outcomes. There have been many studies on various diagnostic haematological markers like acute phase reactants, C-reactive protein, procalcitonin, interleukins and presepsin...

BACKGROUND: During pregnancy, fetal growth causes an increase in the total number of rapidly dividing cells, which leads to increased requirements for folate. Inadequate folate intake leads to a decrease in serum folate concentration, resulting in a decrease in erythrocyte folate concentration, a rise in homocysteine concentration, and megaloblastic changes in the bone marrow and other tissues with rapidly dividing cells OBJECTIVES: To assess the effectiveness of oral folic acid supplementation alone or with other micronutrients versus no folic acid (placebo or same micronutrients but no folic acid) during pregnancy on haematological and biochemical parameters during pregnancy and on pregnancy outcomes...

Premature infants especially those with birth weight < 1500 g suffer from Anaemia of prematurity (AOP) and associated problems. Erythropoietin therapy is a safe effective way to prevent and to treat anaemia of prematurity. To evaluate the effect of short-term administration of recombinant human erythropoietin (rHuEPO) with iron and folic acid in very low birth weight (VLBW) neonates in the prevention of anaemia of prematurity. A randomized controlled trial was carried out at Dhaka Shishu Hospital. Sixty preterm very low birth weight (PTVLBW) babies were enrolled in this study...

AIM: To determine whether adding recombinant erythropoietin to the intravenous (IV) solution and administering it as a 24-h continuous infusion would result in an erythropoietic effect not inferior to that seen with subcutaneous (SC) administration. METHODS: Infants weighing ≤1500 grams and ≤32 weeks of gestational age were randomly assigned at 72 h of life to receive erythropoietin (300 units/kg, 3 times a week until 36 complete weeks of postmenstrual age or discharge), either subcutaneously [erythropoietin subcutaneous (ESC) group] or added to IV fluids [erythropoietin intravenous (EIV) group]...

Over 2 billion people in both developing as well as developed countries - over 30% of the world's population - are anaemic. With the classical preconception that oral iron administration or the intake of foods rich in iron increase haemoglobin concentration and reduce the prevalence of anaemia, specific programs have been designed, but iron supplementations have been less effective than expected. Of note, this hazardous simplification on iron status neglects its distribution in the body. The correct balance of iron, defined iron homeostasis, involves a physiological ratio of iron between tissues/secretions and blood, thus avoiding its delocalization as iron accumulation in tissues/secretions and iron deficiency in blood...

OBJECTIVE: Necrotizing enterocolitis (NEC) is a leading cause of morbidity and mortality in preterm infants born prior to 32 weeks gestation or with a birth weight less than 1500 grams. In this article, we review hematological abnormalities associated with NEC. METHODS: A literature search was performed using the databases PubMed, EMBASE, and Scopus, and the electronic archive of abstracts presented at the annual meetings of the Pediatric Academic Societies. RESULTS: Thrombocytopenia, disseminated intravascular coagulation, increased or decreased neutrophil counts, and hemolytic anemia are frequent events in NEC...

BACKGROUND: Preterm infants are at risk of exhausting their body iron stores much earlier than healthy term newborns. It is widespread practice to give enteral iron supplementation to preterm and low birth weight infants to prevent iron deficiency anaemia. However, it is unclear whether supplementing preterm and low birth weight infants with iron improves growth and neurodevelopment. It is suspected that excess exogenous iron can contribute to oxidative injury in preterm babies, causing or exacerbating conditions such as necrotising enterocolitis and retinopathy of prematurity...

The purpose of this investigation was to describe the characteristics of the use of systemic antifungal agents (AFAs) and to evaluate their appropriateness of use. A prospective drug-utilisation study was conducted in intensive-care areas: haematology-oncology services and transplant units. Data were collected in three periods over 9 months. The required sample size was determined to be 113 patients (margin of error ±7%, 95% confidence interval [CI]), assuming a variability of 50%. Two different investigator groups evaluated the appropriateness of use separately; Cohen's Kappa index was used to calculate the degree of agreement between groups...

Neonatal stroke is a diverse clinical entity. Terminology and aetiology described in the literature are very varied. While numerous risk factors are cited, only few case-control studies have investigated them in a systematic fashion. This equipoise extends to the investigational and management profile of perinatal stroke too. Controversy persists about the suitability of detailed haematological thrombophilia workup in the neonatal period. This case-based review details the variable clinical presentation in term and preterm neonates, discusses the current literature, ascertains the respective roles of various imaging modalities, explores relevant new neuroprotective interventions and proposes a systematic approach to clinical and neuroimaging workup...
