Neutropenia: Understanding Causes, Symptoms, and Challenges

Neutrophils are the type of white blood cell that attack bacteria in blood and defends

against bacterial infections. Neutropenia is a very rare blood condition that causes the body to

have a reduced amount or lack of those neutrophils. Since the lack of cells, those who are

diagnosed with neutropenia are more likely to have a greater risk of infection and many of those

infections can be deadly. There are many ways that someone could be diagnosed with

Neutropenia such as developing it during chemotherapy, certain viral infections, and others may

even be born with it.



To thoroughly understand the causes, it’s also important to understand the symptoms.

Neutropenia doesn’t have symptoms it’s the infections that do. Symptoms for infections may

include fever, fatigue, sore throat, etc. However, if you have mild neutropenia, you might not

experience any symptoms because your body doesn’t have the blood cells to fight infections.

Mild neutropenia might not even require treatment and usually isn’t heavily worried about in the

medical field. Most mild cases don’t cause frequent infections therefore not needing hospital

stays.


About 1 in every 200,000 people have severe congenital neutropenia. Approximately

50% of all chemotherapy patients will develop some level of neutropenia. As far as treatment


goes the most common types of treatment for neutropenia are antibiotics, corticosteroids, and

granulocyte colony-stimulating factor (G-CSF). There are some cases where bone marrow and

stem cell transplants are also needed. These treatments stimulate your bone marrow to produce

more infection-fighting cells.


Adding on, recent research determined that advances in genetic and immunological

diagnostics combined with targeted therapies have improved risk stratification and outcomes.

While it seems small, neutropenia affects approximately 35.5 million adults. Bringing up the

main cause (those undergoing chemotherapy) patients under 65 receiving cancer treatments

experience an up to 16% rate of grade 4 (severe) neutropenia. As shown neutropenia is important

because it’s a side worry during cancer treatments as well as can affect someone from birth.

Neutrophils (white blood cells) fight infection and those who have little to none have may

struggles. Support is heavily needed to let those with neutropenia know that they aren’t fighting

alone and could support further research to help patients struggling with neutropenia.


To finish, neutropenia is a blood disorder that results in little to no production of

neutrophils (white blood cells) in the body. Typically prominent in cancer patients, those born

with the disorder, or those with vital infections and taking medication for it. 35.5 million people

are affected by this disorder and it’s vital to know about it so that more patients can continue to

get the help they deserve. It’s never easy to have to fight repeated infections that involve rough

symptoms that could be deadly. Neautropenia is important and should continue to be advocated

for.

Understanding Cystic Fibrosis

Blog written by Alyza Kour - Reasearch Lead of Teen Med Spot   Mucus in our body is more than just “gross stuff” coming out our nose when we have a cold, it’s actually a vital protective layer. Its job is to line our lungs, digestive tract, and other organs to keep them moist and to trap dust, bacteria, or virusese so your body can get rid of them. Healthy mucus is thin, slippery, and water (Think of it like a layer of liquid soap). ( Cleveland Clinic ) What is cystic fibrosis? It is a genetic disease that causes sticky, thick mucus to build up in your organs (Lungs, Digestive System, Pancreas), blocking and damaging them. ( Cleveland Clinic.org ) What causes cystic fibrosis? Changes to the CFTR gene - called variants or mutations - cause cystic fibrosis. CFTR makes a protein that works as an ion channel on the surface of a cell. Ion channels are like gates in a cell’s membrane that allow certain molecules to pass through. Think of this protein as a “gate” for chloride ions (sa...

Uncovering the Clinical Characterization and Mechanisms of Fibrodysplasia Ossificans Progressiva (FOP) By: Sharen Rego

Image
 Introduction Fibrodysplasia Ossificans Progressiva or FOP is an exceedingly rare, yet severely disabling genetic disorder, characterized by the abnormal formation of bone tissue outside of the normal human skeleton (heterotopic ossification). This can occur within soft tissues like the skeletal muscles, tendons, and ligaments. With an estimated one in two million people affected globally, FOP represents one of the most complex genetic conditions known to modern medicine. Raising awareness for this disorder is crucial, as early symptoms are often misdiagnosed as cancer, leading to harmful medical interventions like biopsies or routine muscle injections which trigger irreversible bone growth. Main Body At the cellular level, FOP is caused by a specific mutation in the ACVR1 gene located on chromosome 2. This gene provides instructions for making a specialized receptor protein that controls when and where the body builds bone tissue (such as during fetal development or when healing a...

Understanding Ehlers-Danlos Syndrome (EDS) By: Zella Shanks (Current Campaign)

Image
  Introduction   What is Ehlers-Danlos Syndrome (EDS)? Ehlers-Danlos Syndrome, also known as EDS, is a group of genetic disorders that affect the body’s connective tissues. Connective tissue is found almost everywhere in the body and helps hold everything together, including your own skin, joints, muscles, and blood vessels. People that have Ehlers-Danlos Syndrome have problems with collagen, which is one of the many main proteins that gives connective tissues its strength and flexibility. When collagen doesn’t work the way it’s supposed to, the body’s tissues become weaker and more likely to stretch or to get injured. Why Is It Important?    Even though EDS isn’t very well known, it can have a huge effect on someone’s everyday life. Many people deal with ongoing pain, fatigue, joint injuries, and other symptoms that can make normal activities more difficult. While there isn’t a cure yet, getting diagnosed early and learning how to manage the condition can ...
