How Hepcidin Regulates Serum Iron in People with Anemia

Anemia, is a condition that affects millions of people worldwide.

If you or someone you know has been diagnosed with anemia, you’re likely familiar with its symptoms; fatigue, weakness, and a general sense of feeling unwell.

But what’s the story behind anemia? Why does it happen, and how is it connected to hepcidin?

In this blog post, we’ll explain the relationship between hepcidin and anemia in a simple way.

We’ll break down complex scientific concepts into easy-to-understand language and discuss how hepcidin regulates the amount of iron in your blood.

We’ll also provide tips for managing your iron levels and offer a glimpse into the exciting future of anemia research.

Whether you are new to anemia or you want to learn more about this topic, this guide to hepcidin and iron regulation will help you.

Things to keep in mind about hepcidin and anemia:

• Hepcidin levels are affected by a number of factors, including inflammation, infection, and certain diseases.

• Low hepcidin levels can lead to iron overload, while high hepcidin levels also leads to iron deficiency.

• There are a number of drugs that can affect hepcidin levels.

• Research is ongoing to develop new treatments for anemia that target hepcidin.

What’s Hepcidin and What Does It Do?

Hepcidin is a small protein that is produced in the liver, it’s role is to help regulate iron levels in the body.

Hepcidin binds to a protein called ferroportin, which is located on the surface of cells that store or release iron.

When hepcidin binds to ferroportin, it causes the cell to destroy the iron that is stored inside. This helps to keep iron levels in the body in check.

Hepcidin levels are tightly regulated by a number of factors, such as iron levels, inflammation, and infection.

When iron levels are high, hepcidin levels increase. This helps to reduce iron absorption from the gut and also promotes the removal of iron from tissues.

When serum iron levels are low, hepcidin levels reduces. This allows for increased iron absorption and storage.

How Hepcidin Can Help You Beat Anemia

In recent years, scientists have learned that hepcidin is a key player in the development of anemia.

In iron deficiency anemia, hepcidin levels are low, which allows for increased iron absorption and storage. This helps to correct iron deficiency.

However, in other types of anemia, such as anemia of inflammation, hepcidin levels are high.

This blocks iron absorption and release, which then leads to iron deficiency and anemia.

In anemia of inflammation, hepcidin levels are high due to the release of pro-inflammatory cytokines.

These cytokines signal the liver to produce more hepcidin, which then blocks iron absorption and release.

This further decreases iron levels and worsen the anemia.

How Hepcidin Works

Hepcidin is a small peptide hormone that is produced by the liver and is released into the bloodstream.

It helps to regulate iron metabolism by controlling the amount of iron that is absorbed from the diet and released from storage.

Hepcidin binds to ferroportin, which is found on the surface of cells that export iron, like enterocytes in the small intestine and macrophages in the liver and spleen.

When hepcidin binds to ferroportin, it causes the ferroportin protein to be internalized and degraded.

This prevents the enterocytes from exporting iron, which decreases the amount of iron in the bloodstream.

The production of hepcidin is regulated by a number of factors, including the level of iron in the body, the presence of inflammation, and the need for iron for red blood cell production.

When serum iron levels are high, hepcidin production is increased, which helps to reduce the amount of iron in the body.

When serum iron levels are low, hepcidin production is decreased, which allows the body to absorb more iron from the diet.

Inflammation also increases hepcidin production, because it can damage cells and release iron from them.

Hepcidin helps to prevent this iron from being absorbed by other cells, which helps to protect the body from the harmful effects of iron overload.

When the body needs more iron for red blood cell production, hepcidin production is decreased to allow more iron to be absorbed from the diet.

Hepcidin is a critical hormone that maintains iron homeostasis, prevents iron overload, and makes sure your body has enough iron for making red blood cells.

Summary: Hepcidin is produced in the liver and released into the blood. It binds to ferroportin, located on the surface of cells that store or release iron. When hepcidin levels are too high, it leads to iron deficiency and anemia. This happens in conditions like hemochromatosis, anemia of inflammation, and chronic kidney disease. When hepcidin levels are too low, it can lead to iron overload, heart disease and liver damage.

What Affects Hepcidin Levels?

A number of factors can influence hepcidin levels, including:

• When serum iron levels are high, hepcidin levels also increase.
• Pro-inflammatory cytokines increases hepcidin levels.
• Infection also increase hepcidin levels.
• People with kidney disease have high hepcidin levels.
• Mutations in the HAMP gene increases hepcidin levels and iron deficiency anemia.

Other factors also affects hepcidin levels as well, including:

• Inflammation: Hepcidin levels increase in response to inflammation. This is because inflammation is a sign that the body is under attack, and hepcidin helps to protect the body by limiting the amount of iron available to bacteria and other pathogens.
• Erythropoietin (EPO): EPO stimulates the production of red blood cells. Hepcidin levels decrease in response to EPO. This is because EPO helps to increase the demand for iron, and hepcidin helps to make more iron available for red blood cell production.
• Hypoxia: Hepcidin levels decrease in response to hypoxia because hypoxia is a sign that the body needs more iron, and hepcidin helps to make more iron available for the tissues.

The body adjusts hepcidin levels based on its iron needs.

For example, when you are bleeding, your body will increase hepcidin levels to prevent iron loss.

When you are eating lots of iron-rich foods, your body will decrease hepcidin levels to allow for more iron absorption.

Making Sense of It All: What It Means for Anemia Patients

The discovery of hepcidin has helped scientists to better understand the causes of anemia.

This knowledge is being used to develop new treatments for anemia, such as medications that can lower hepcidin levels.

If you have anemia, taking iron supplements or adjusting your diet can be of great help, but it is also important to:

• Avoid foods that are high in phytates, such as beans, nuts, and seeds. Phytates can bind to iron and make it harder to absorb.
• Avoid foods that are high in calcium. Calcium interferes with the absorption of iron, so eating too much calcium Increases hepcidin levels.
• Eat foods that are high in vitamin C, such as citrus fruits, tomatoes, and broccoli. Vitamin C improves iron absorption.
• Drink plenty of water. This will help to keep your body hydrated and improve iron absorption.

If you have anemia of inflammation, there are a few drugs that can help lower hepcidin levels in people with anemia of inflammation. These drugs include:

• Ribociclib (Kisqali): This drug is a cyclin-dependent kinase inhibitor that is used to treat cancer.
• Baricitinib (Olumiant): This drug is a JAK inhibitor that is used to treat rheumatoid arthritis and other autoimmune diseases.
• Tocilizumab (Actemra): This drug is a monoclonal antibody that is used to treat rheumatoid arthritis and other autoimmune diseases.
• Eltrombopag (Promacta): This medication is a thrombopoietin receptor agonist that is used to treat thrombocytopenia.

These drugs are still under development, but they have shown promise in clinical trials.

It is important to note that these drugs are not a cure for anemia of inflammation.

They only help to lower hepcidin levels and improve iron levels, but they will not reverse the underlying inflammation that is causing the anemia.

What to Eat to Keep Hepcidin Levels Normal

There are a few things you can do to keep your hepcidin levels in check by eating a healthy diet. These include:

• Eating plenty of fruits and vegetables that are high in vitamin C.
• Avoiding processed foods. Processed foods are high in iron, which can raise hepcidin levels.
• Eating lean protein. Lean protein is a good source of iron, but it does not raise hepcidin levels as much as red meat.

There are also foods that can help you absorb iron better, such as
oranges, tomatoes, and broccoli.

What’s Next in Anemia Research?

Scientists are still learning about anemia and how to treat it. Here are some of the areas of research that are being discussed:

• Developing new drugs that can lower hepcidin levels.
• Understanding the role of hepcidin in heart disease and cancer.
• Developing ways to measure hepcidin levels in a non-invasive way.

Knowing that hepcidin is important for anemia could help us find new ways to treat it.

Which means that we can target hepcidin to develop new treatments for the condition.

For example, we could develop drugs that can block hepcidin production or increase hepcidin degradation.

This could help to improve iron absorption and red cell production, which could lead to better outcomes for people with anemia.

Wrapping It Up

In this post, we’ve talked about how hepcidin regulates serum iron levels in anemia, and how it affects iron absorption and storage.

The relationship between anemia and hepcidin is important because hepcidin levels can affect various types of anemia.

Factors like inflammation, infection, and diseases affect hepcidin, and research aims to develop targeted treatments.

To manage iron levels, what you eat and drink matters. Also, scientists are looking into new medicines for specific anemia types.

Understanding hepcidin’s role could lead to better anemia treatments and make life easier for people with anemia.
