Insights

Neonatal screening and comprehensive care significantly reduce sickle hemoglobinopathy mortality. However, new research offers hope for better management of complications and potential curative therapies.

Area of Science:

  • Hematology
  • Pediatric Medicine
  • Genetics

Background:

  • Neonatal screening and comprehensive care, including penicillin prophylaxis and immunizations, have greatly decreased infant mortality from sickle hemoglobinopathies.
  • Despite advances in understanding pathophysiology, current treatments inadequately prevent acute noninfectious complications (e.g., pain crises, strokes) and chronic organ damage.

Purpose of the Study:

  • To review recent advancements in understanding sickle hemoglobinopathies.
  • To highlight improvements in managing acute complications and the emergence of potentially curative therapies.

Main Methods:

  • Review of recent publications on sickle hemoglobinopathies.
  • Analysis of current therapeutic approaches and ongoing clinical trials.

Main Results:

  • Increased knowledge of factors contributing to clinical heterogeneity in sickle hemoglobinopathies.
  • Modest improvements in identifying and treating acute complications.
  • Emerging hope for curative treatments, with ongoing trials for hydroxyurea and bone marrow transplantation.

Conclusions:

  • While neonatal screening and supportive care have improved survival, significant challenges remain in managing disease complications.
  • Recent research offers promising avenues for more effective treatments and potential cures for sickle hemoglobinopathies.

Multiple Allele Traits02:19

Multiple Allele Traits

For the same gene multiple alleles can interact to influence phenotypes like the shape and protein composition of an individual cells.By studying allele interactions on the molecular and cellular levels researchers can understand the resulting phenotypes and complications of human conditions like sickle cell trait, improving treatment.The ABO blood group system is a common example of multiple alleles in humans. This system includes three alleles called IA, IB, and i alleles, which combine in...
Disorders of Erythrocytes01:27

Disorders of Erythrocytes

Disorders of erythrocytes, or red blood cells (RBCs), include a range of conditions affecting their number, shape, or function.
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.
On the other...
Hemoglobin01:24

Hemoglobin

Hemoglobin is a globular protein made up of four subunits. Two of these subunits are alpha chains, and the other two are beta chains. Each subunit contains a molecule of heme, which has an iron atom and can bind to oxygen. When an oxygen molecule binds to one heme group, it changes the shape of hemoglobin, making it easier for the other heme groups to bind oxygen as well.
When all four heme groups are bound to oxygen, the resulting molecule is called oxyhemoglobin. As a result, arterial blood...
Alternative RNA Splicing02:18

Alternative RNA Splicing

Alternative RNA splicing is the regulated splicing of exons and introns to produce different mature mRNAs from a single pre-mRNA. Unlike in constitutive splicing where a single gene produces a single type of mRNA, alternative splicing allows an organism to produce multiple proteins from a single gene and plays an important role in protein diversity.
There are five types of alternative RNA splicing that vary in the ways the pre-mRNA segments are removed or retained in the mature mRNA. The first...
Disorders of Hemostasis01:24

Disorders of Hemostasis

Hemostasis, the process that stops bleeding after a blood vessel injury, is crucial for maintaining the integrity of the circulatory system. However, disorders of hemostasis can disrupt this delicate balance, leading to either excessive clotting or bleeding. These disorders can be broadly classified into thromboembolic disorders and bleeding disorders.
Thromboembolic Disorders
Two factors primarily cause thromboembolic conditions.
Gene Families01:57

Gene Families

Gene families consist of groups of genes proposed to have originated from a common ancestor. Typically these arise through events in which a gene or genes are mistakenly duplicated during cell division. Unlike their parent genes (which are subject to selection pressure to maintain function), these gene copies do not need to preserve their sequences and may evolve at a relatively faster rate.
Occasionally these regions can be adapted to take on new roles within the organism, becoming novel genes...
