What is Paroxysmal Nocturnal Hemoglobinuria?

Introduction

Paroxysmal Nocturnal Hemoglobinuria (PNH) is a rare blood disorder. In this condition, red blood cells break down too early. As a result, people with PNH may feel tired, weak, or notice dark urine. Although PNH is not common, it can cause serious health problems. In this blog, you will learn about the causes, symptoms, diagnosis, and treatment of Paroxysmal Nocturnal Hemoglobinuria. We will use simple language to help you understand this complex disease.

Causes and Risk Factors

PNH happens because of a change, or mutation, in the DNA of some blood cells. This change is not inherited from parents. Instead, it occurs during a person’s life. Because of this mutation, red blood cells lack a protective shield. Without this shield, the immune system attacks and destroys these cells.

Although anyone can get PNH, it is very rare. Most people are diagnosed in their 30s or 40s. However, it can affect both men and women. Sometimes, PNH is linked to other bone marrow problems, such as aplastic anemia.

  • Not inherited from parents
  • Caused by a random change in blood cell DNA
  • Can occur at any age, but more common in adults
  • May be linked to other bone marrow diseases
  • Common Symptoms and Warning Signs

    PNH symptoms can vary from person to person. Some people have mild symptoms, while others have severe problems. Often, symptoms appear slowly and may be missed at first. However, knowing the warning signs can help you seek care early.

  • Dark or reddish urine, especially in the morning
  • Feeling very tired or weak
  • Shortness of breath
  • Headaches
  • Pain in the belly or chest
  • Easy bruising or bleeding
  • Frequent infections
  • Blood clots, which can cause swelling or pain in the legs
  • Because these symptoms can be caused by other conditions, it is important to talk to a doctor if you notice them. Early diagnosis can help prevent serious problems.

    How Paroxysmal Nocturnal Hemoglobinuria is Diagnosed

    Doctors use several tests to diagnose PNH. First, they will ask about your symptoms and medical history. Next, they may order blood tests to look for signs of red blood cell breakdown. One key test is called flow cytometry. This test checks if your blood cells are missing certain protective proteins.

    In some cases, doctors may also do a bone marrow test. This helps them see how well your body is making blood cells. According to the National Institutes of Health, these tests are the best way to confirm PNH.

  • Blood tests for hemoglobin and red blood cell breakdown
  • Flow cytometry to check for missing proteins
  • Bone marrow test if needed
  • Treatment Options and Management

    Although there is no cure for PNH, several treatments can help manage symptoms. The choice of treatment depends on how severe your symptoms are. Some people need only regular check-ups, while others need medicine or procedures.

  • Medicines: Drugs like eculizumab and ravulizumab help protect red blood cells. These medicines can lower the risk of blood clots and reduce symptoms.
  • Blood transfusions: Some people need extra red blood cells if they become very anemic.
  • Bone marrow transplant: In rare cases, a transplant may cure PNH. However, this is a major procedure with risks.
  • Blood thinners: These may be used to prevent blood clots.
  • Doctors will work with you to find the best plan. According to the World Health Organization, early treatment can improve quality of life and lower the risk of complications.

    Lifestyle Tips and Prevention

    While you cannot prevent PNH, you can take steps to stay healthy. For example, regular doctor visits help catch problems early. Eating a balanced diet and staying active can support your overall health. If you take medicines, follow your doctor’s instructions closely.

  • See your doctor for regular check-ups
  • Report new symptoms right away
  • Stay active as much as possible
  • Eat a healthy, balanced diet
  • Take medicines as prescribed
  • Although PNH cannot be prevented, these steps can help you manage the condition better.

    When to See a Doctor

    If you notice dark urine, unusual tiredness, or any of the symptoms listed above, see a doctor soon. Early diagnosis and treatment can prevent serious problems. If you have PNH and develop new symptoms, contact your healthcare provider right away. Remember, regular follow-up is key to staying healthy with PNH.
