Paroxysmal Nocturnal Hemoglobinuria: Warnings Signs You Shouldn’t Ignore

4 min read

By Clarissa Vanner

Though rare, paroxysmal nocturnal hemoglobinuria (PNH) is a life-threatening disease of the blood. It occurs when your immune system attacks and damages red blood cells and platelets. If left untreated, PNH can lead to serious outcomes. This is why it’s crucial to know the warning signs. Fortunately, you can learn everything you need to know about paroxysmal nocturnal hemoglobinuria with a search online right now, which could help you spot the early warning signs.

What Is Paroxysmal Nocturnal Hemoglobinuria?

Paroxysmal nocturnal hemoglobinuria, or PNH for short, is a rare but serious blood disorder that affects the way our red blood cells work. In people with PNH, their body mistakenly attacks its healthy red blood cells, causing them to break down too early.

PNH often begins with a telling symptom: red, brown, or dark urine during late-night or early-morning trips to the toilet. This occurs due to the breakdown of red blood cells by the immune system, a process known as hemolysis. However, dark-colored urine is just one of the many symptoms that might signal underlying health issues. Without proper treatment, PNH can lead to serious consequences. Understanding PNH is essential to identify it early and seek proper medical attention.

Hemoglobinuria vs. Hematuria: What’s the Difference?

Both conditions share the presence of blood in the urine, but they differ in the nature of the blood components. Hematuria involves red blood cells in the urine, giving it a red color, while hemoglobinuria refers to the presence of hemoglobin, a protein found in red blood cells, which also imparts a red hue to the urine.

Understanding this distinction is crucial for accurate diagnosis and appropriate treatment, as it helps healthcare providers determine the underlying cause of blood in the urine and provide targeted care for the specific condition.

Who’s At Risk?

PNH is a rare condition, affecting about 6 per 1 million people each year. This disorder is commonly diagnosed in both men and women, particularly between the ages of 30 and 40, with women being slightly more susceptible to developing PNH.

Individuals who already have bone marrow disorders like aplastic anemia or myelodysplastic syndrome are also at a higher risk of developing PNH. Understanding the risk factors associated with PNH can help individuals and healthcare providers stay vigilant and ensure timely screenings and interventions for those at higher risk.

Warning Signs You Shouldn’t Ignore

Recognizing the warning signs of PNH is crucial for early detection and timely treatment. In addition to dark urine, you should also watch out for unexplained fatigue that doesn’t go away even with rest, frequent episodes of paleness or unusual weakness, and a tendency to bruise or bleed easily. If you notice any of these warning signs, don’t ignore them; seek medical advice promptly to safeguard your health.

What Causes PNH?

PNH is caused by a missing gene called PIG-A, which plays a crucial role in helping proteins stick to blood cells. Without this gene, important proteins can’t protect the cells from substances in the blood called complement. As a result, red blood cells break down too early, leading to the release of hemoglobin into the blood, which can end up in the urine. This condition can happen at any age and might be linked to aplastic anemia, myelodysplastic syndrome, or acute myelogenous leukemia.

How Is PNH Diagnosed?

Diagnosing PNH involves a series of tests performed by healthcare providers to look for specific signs. Some of these tests include a complete blood count with differential (CBC w/diff) to check for blood disorders like anemia and thrombocytopenia, as well as a basic metabolic panel (BMP) to assess kidney function.

Your doctor may also request a urinalysis, which can reveal signs of hemoglobinuria (blood in pee) and hemosiderosis (excess iron deposits). There are also a few other tests and you can learn more by searching online. Researching ahead of time can help you understand what to expect during the diagnostic process.

Treating PNH: What Are The Options?

To combat the destructive effects of PNH, healthcare providers now utilize targeted therapies known as complement inhibitors. In the past, those with PNH relied on regular red blood cell transfusions to manage anemia caused by the condition. However, this approach often resulted in a limited life expectancy of 10 to 22 years after diagnosis. The only potential cure was an allogeneic stem cell transplant. But with the arrival of complement inhibitors, studies now demonstrate that individuals receiving this treatment can expect to enjoy a life expectancy similar to someone without PNH, offering newfound hope and improved outcomes.
