Hemolytic Uremic Syndrome (HUS) Renal Disease


Hemolytic Uremic Syndrome (HUS) Renal Disease

What is hemolytic uremic syndrome? HUS is a rare but serious disease that affects the kidneys and blood clotting functions of infected people. Infection with HUS causes destruction of red blood cells, which can then cause kidney failure. HUS occurs as a complication of a diarrheal infection (usually E.

What disease causes hemolytic uremic syndrome?

What causes HUS? Most cases of HUS occur after an infection in the digestive tract caused by the E. coli bacterium, O157:H7. Diarrhea and upper respiratory infections are the most common factors leading to HUS.

How does HUS cause hemolytic anemia?

Pathophysiology of HUS

Endothelial damage is common. Loose strands of platelets and fibrin are deposited in multiple small vessels and damage passing platelets and red blood cells (RBCs), causing significant thrombocytopenia and anemia (microangiopathic hemolytic anemia).

What is the triad of HUS?

Hemolytic uremic syndrome (HUS) is primarily a disease of infancy and early childhood and is classically characterized by the triad of microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury.

What are the 5 symptoms of hemolytic uremic syndrome?

Symptoms of HUS include vomiting, bloody diarrhea (loose stool/poop), stomach pain, fever, chills, and headache. As infection progresses, persons may experience fatigue, weakness, fainting, bruising, and paleness.

Which of the following renal disorders is associated with obesity?

4, 5 Obesity-related glomerulopathy (ORG) is the best-known renal disease secondary to obesity. From observation of this unique disease state, significant knowledge has accumulated regarding the clinicopathological characteristics of renal injury in obesity.

Is HUS treatable?

How is HUS treated? HUS is generally treated with medical care in the hospital. Fluid volume management is crucial and may include: intravenous (IV) fluids.

How do you know if you have HUS?

Early symptoms of HUS include decreased urine output, diarrhea, and feeling slow and tired (lethargy). Low red blood cell count (anemia), low platelet count, and decreased kidney function are signs that might be detected by laboratory testing.

Does hemolytic uremic syndrome cause thrombocytosis?

Hemolytic-uremic syndrome (HUS) is a clinical syndrome characterized by progressive kidney failure that is associated with microangiopathic (nonimmune, Coombs-negative) hemolytic anemia and thrombocytopenia. HUS is the most common cause of acute kidney injury in children and is increasingly recognized in adults.

Are there different types of hemolytic uremic syndrome?

HUS is classified into three primary types: (1) HUS due to infections, often associated with diarrhea (D+HUS), with the rare exception of HUS due to a severe disseminated infection caused by Streptococcus; (2) HUS related to complement abnormalities or related to factor-ADAMTS13 deficit, such HUS is also known as …

Can HUS cause liver damage?

During the recovery stage of the hemolytic uremic syndrome in 2 cases an increase of serum levels of GOT, GPT, LDH, gammaGT, 5’ND and AP was noticed, without signs of a recurrence of the disease. In one patient also jaundice and hepatomegaly were found. The observations suggest a parenchymal damage of the liver.

Can you prevent HUS?

coli, there’s nothing you can do to prevent it from developing into HUS. The key is to avoid the E. coli infection. To lower your risk of being infected with E.

Can HUS cause brain damage?

Heart and lung injury is rare in HUS, but can be fatal if it occurs. Brain damage (encephalopathy) can cause stroke or cerebral edema (swelling of the brain) and is the most frequent cause of death in HUS patients.

How does obesity cause nephrotic syndrome?

When fatty acids bind to albumin, the toxicity to proximal renal tubules is magnified. Albumin and fatty acids are elevated in urine of individuals with obesity related nephrotic syndrome. Fatty acid accumulation and resistin inhibit insulin and adiponectin.

Can obesity cause proteinuria?

Obesity is associated with proteinuria and a more rapid progression of CKD8 and the reversal of obesity can improve proteinuria9,10 and GFR. Moreover, there is evidence that obesity causes glomerular hypertrophy and impaired glomerular function, even in the absence of a primary kidney disease.

What is nephropathy?

Nephropathy is the deterioration of kidney function. The final stage of nephropathy is called kidney failure, end-stage renal disease, or ESRD. According to the CDC, diabetes is the most common cause of ESRD.

How do you test for uremic syndrome?

To confirm a diagnosis of HUS , your doctor is likely to perform a physical exam and recommend lab tests, including:
  1. Blood tests. These tests can determine if your red blood cells are damaged. …
  2. Urine test. This test can detect abnormal levels of protein, blood and signs of infection in your urine.
  3. Stool sample.

How long does HUS last?

The initial symptoms of HUS frequently last from one to 15 days and may include symptoms in the digestive tract, such as the following: Abdominal pain.

How is HUS transmitted?

HUS cannot be spread from person-to-person. However, STEC, Shigella and other organisms that can cause HUS can be spread through eating or drinking contaminated food or water or contact with a person who is ill.

Can E. coli damage your kidneys?

It can cause stomach cramps, fever, diarrhea and vomiting. STEC infection can be mild and resolve itself after five to seven days. It can also be severe for some people and can lead to kidney failure. STEC infection can cause a condition called hemolytic uremic syndrome (HUS), which is a type of kidney failure.

Can kidneys affect platelets?

In addition to anemia, platelet count also seems to be affected by renal disorder too. The exact pattern of platelet count in patients with renal failure is controversial but several studies revealed the decrease in platelet count in renal failure.

Can HUS cause seizures?

As with TTP, seizures can be associated with HUS for several reasons: Vascular damage in cortical regions, creating a seizure focus or foci. Metabolic imbalance (e.g., uremia, hyponatremia, fever)90,101103. Cerebral hemorrhage due to thrombocytopenia102.
