IgA Nephropathy

IgA Nephropathy Basic

iga nephropathy basics

IgA Nephropathy (IgAN, or Berger's disease) is the most common glomerulonephritis found in the developed countries of the world. IgA is short for immunoglobulin A, an antibody which usually helps the body to fight infections and toxins invaded into the body. In IgA Nephropathy, IgA and immune complex (antibody+antigen) are deposited in the mesangial area of the kidneys.

Causes and risk factors

The disease can affect people an any age although it is more common in men. Caucasians and Asians also have a higher incidence of IgA kidney disease.

Generally, IgA Nephropathy occurs due to disordered immune system. In other cases, the disease can develop after a kid or young adult develop a viral infection of the upper respiratory or gastrointestinal tracts. In some cases, a genetic defect may be associated with the development of this renal disease.

Exams and Tests

• Conventional tests: urine test, blood test, and kidney biopsy.

• Immune special examination and diagnosis

- Kidney damage tests. Checking items include: UTP, U-malb, U-TRF, U-IGG, β 2-microglobulin, α1-microglobulin, α2-macroglobulin, κ light chain, λ light chain, U- NAG, U-GGT, and Uosm.

- Toxins in blood test. Checking items include: BUN, Creatinine, UA, β 2-microglobulin, Cyc C, RBP, HCY, and PTH.

- Hameturia position. Test results include glomerular hematuria, non-glomerular hematuria, and mixed hematuria.

- Tests for sub-group of lymphocysts. It contains 15 indexes to indicate the antibody conditions in your blood, such as CD4, CD8, NK cells, B cells, T Cells etc. Each of them can reflect a specific factor of your immune functions.

- Complement in blood serum test. This test include C3, C4, CH50, C3B, etc.


20-40% of the patient progress to End Stage Kidney Failure about 20 years after the disease becomes apparent. Those who have elevated serum creatinine level at the time of their diagnosis are more prone to Chronic Kidney Failure. Generally speaking, a poor prognosis is expected for patients who have increased blood pressure, proteinuria (>2 g/day), and a significant amount of damage present in their biopsy specimen.

IgA Nephropathy Symptoms

iga nephropathy symptoms

IgA Nephropathy usually doesn't cause symptoms in the early stages. The disease can go unnoticed for decades. When kidney function is impaired, signs and symptoms as below will occur.

• Hematuria, or Blood in Urine

This is the most common sign. In most cases, this is such a small amount of blood that it can not be seen and it can only be visible with the aid of a microscope.

Some individuals will actually be able to see blood in their urine. Typically, this happens in young people when they have a sore throat or chest infection. Less frequently, this happens with a gastrointestinal infection, strenuous exercise, or vaccination.

• Foamy or bubbly urine

This is due to Protein in Urine, or proteinuria. Proteinuria will usually start out heavy when the disease first appears. Like blood in urine, it can be exacerbated by respiratory or other illnesses, or even by emotional stress.


The dominant complaint of most patients is of fatigue, which can be overwhelming. They may have problems such as a sore throat, headache, or some other problem.

• Flank pain

Many patients may suffer from bouts of flank pain, which can range from a dull ache in the back to debilitating spasms that make walking and rising difficult.

High Blood Pressure

This is not usually found when IgA Nephropathy is first diagnosed, but it often develops in the course of this disease.

Swelling, or edema

Swelling of the hands, ankles, feet, and other parts of the body is also a common sign caused by fluid retention.

Other symptoms may include frequent urination (especially at night), nausea, mood swings, becoming more susceptible to allergies, losing sensitivity to temperature change, etc.
