IgA Nephritis: Not Always a Cold

IgA nephropathy (IgAN), also known as Berger's disease, is a chronic inflammatory kidney disease that affects the glomeruli, the tiny filters in the kidneys that help clean the blood. IgA is a type of antibody, a protein produced by the immune system to fight infection. In IgA nephropathy, IgA antibodies become trapped in the glomeruli, causing inflammation and damage.

IgA nephropathy is often associated with a recent cold or other upper respiratory tract infection. However, it's important to note that not all cases of IgA nephropathy are triggered by a cold. In fact, in many cases, there is no obvious trigger for the disease.

Symptoms of IgA Nephropathy

The symptoms of IgA nephropathy can vary depending on the severity of the disease. In some cases, there may be no symptoms at all. However, in other cases, symptoms can include:

Bloody or cloudy urine

Protein in the urine (proteinuria)

High blood pressure

Swelling in the face, hands, and feet (edema)

Fatigue

Nausea and vomiting

Loss of appetite

Diagnosis of IgA Nephropathy

IgA nephropathy is diagnosed based on a combination of symptoms, a physical examination, and laboratory tests. A urine test will show the presence of blood or protein in the urine. A blood test may show high levels of IgA antibodies. A kidney biopsy may be performed to confirm the diagnosis. A kidney biopsy is a procedure in which a small sample of kidney tissue is removed and examined under a microscope.

Treatment of IgA Nephropathy

There is no cure for IgA nephropathy, but there are treatments that can help to slow the progression of the disease and prevent complications. Treatment options may include:

Medications to lower blood pressure

Medications to reduce inflammation

Medications to suppress the immune system

Lifestyle changes, such as a low-sodium diet and regular exercise

Prognosis of IgA Nephropathy

The prognosis of IgA nephropathy varies depending on the severity of the disease. In some cases, the disease will progress slowly and cause no significant health problems. In other cases, the disease can progress to end-stage renal disease (ESRD), which is a condition in which the kidneys can no longer function properly. ESRD requires dialysis or a kidney transplant.

Prevention of IgA Nephropathy

There is no known way to prevent IgA nephropathy. However, there are some things that may help to reduce the risk of developing the disease, such as:

Getting vaccinated against common cold and other upper respiratory tract infections

Avoiding exposure to toxins and pollutants

Maintaining a healthy diet and lifestyle

IgA Nephropathy and IgA Vasculitis

IgA nephropathy is sometimes associated with a condition called IgA vasculitis. IgA vasculitis is a rare autoimmune disease that causes inflammation and damage to the blood vessels. Symptoms of IgA vasculitis can include:

Purpura, which is a reddish-purple rash that does not blanch when pressed

Joint pain

Abdominal pain

Kidney problems

Lung problems

IgA vasculitis is treated with medications to suppress the immune system.

IgA Nephropathy and Henoch-Schonlein Purpura

IgA nephropathy is also sometimes associated with a condition called Henoch-Schonlein purpura (HSP). HSP is a type of vasculitis that affects small blood vessels in the skin, joints, kidneys, and intestines. Symptoms of HSP can include:

Purpura

Joint pain

Abdominal pain

Bloody stools

Kidney problems

HSP is treated with medications to suppress the immune system.

IgA Nephropathy and Cryoglobulinemia

IgA nephropathy is sometimes associated with a condition called cryoglobulinemia. Cryoglobulinemia is a rare disorder in which abnormal proteins called cryoglobulins form in the blood. Cryoglobulins can cause inflammation and damage to the blood vessels. Symptoms of cryoglobulinemia can include:

Purpura

Joint pain

Weakness

Fatigue

Kidney problems

Cryoglobulinemia is treated with medications to suppress the immune system.

IgA Nephropathy and Other Conditions

IgA nephropathy can also be associated with a number of other conditions, including:

Diabetes

Lupus

Rheumatoid arthritis

Thyroid disease

It is important to note that not all people with IgA nephropathy will develop these other conditions. However, if you have IgA nephropathy, it is important to be aware of the potential risks.
