Does hemolytic anemia cause hemoglobinuria?

Hemoglobinuria classically is ascribed to paroxysmal nocturnal hemoglobinuria, but it can occur with any brisk intravascular hemolytic anemia.

What causes Hemosiderinuria?

Hemosiderinuria (syn. haemosiderinuria) is the presence of hemosiderin in urine. It is often the result of chronic intravascular hemolysis, in which hemoglobin is released from red blood cells into the bloodstream in excess of the binding capacity of haptoglobin.

Why is it called paroxysmal nocturnal hemoglobinuria?

The condition gets its name from one of its symptoms: dark or bright red blood in your urine at night or in the morning. “Paroxysmal” means “sudden,” “nocturnal” means “at night,” and “hemoglobinuria” means “blood in the urine.” It happens in up to 50% of people with PNH.

When do you see Heinz bodies?

Heinz bodies may be present in patients with glucose-6-phosphate dehydrogenase (G6PD), or FAD f(adenine dinucleotide deficiency), i.e. methemoglobinemia. [6] it may also indicate unstable hemoglobin, e.g. HB Koln.

What is MDS and PNH?

Although even rarer than aplastic anemia or myelodysplastic syndromes (MDS), paroxysmal nocturnal hemoglobinuria (PNH) can occur in patents having these diseases. In this interview, Dr. David Araten discusses the rare, and often complex scenario of a dual diagnosis. Here’s what patients and their doctors need to know.

What is the difference between hematuria?

Hematuria can be gross or microscopic. Gross hematuria is visible blood in the urine. Microscopic hematuria refers to the detection of blood on urinalysis or urine microscopy. Hematuria can be intermittent or persistent.

How can you tell the difference between intravascular and extravascular hemolysis?

Intravascular hemolysis occurs when erythrocytes are destroyed in the blood vessel itself, whereas extravascular hemolysis occurs in the hepatic and splenic macrophages within the reticuloendothelial system.
