IgA nephropathy synonyms

TL;DR: IgA nephropathy is most commonly known as Berger's disease, named after the French nephrologist Jean Berger who first described it in 1968. While medical professionals universally use "IgA nephropathy" in clinical practice, patients may encounter historical terms such as "IgA glomerulonephritis" or "synpharyngitic glomerulonephritis" in older medical records or literature.

What are the official names and medical classifications of IgA nephropathy?

In modern clinical practice, IgA nephropathy is the preferred and standard terminology. This name accurately reflects the underlying pathology: the deposition of immunoglobulin A (IgA) immune complexes in the glomeruli of the kidneys. In official medical coding systems, it is classified as follows:

• ICD-10/11: Classified under glomerulonephritis (N02.8 in ICD-10), specifically noted as IgA nephropathy.


• OMIM (Online Mendelian Inheritance in Man): Listed as #161950, reflecting its complex genetic and sporadic nature.


• Orphanet: Recognized as ORPHA:627, where it is categorized as a rare, chronic kidney disease.

Why does IgA nephropathy have so many different names?

The variety of names for IgA nephropathy stems from its relatively recent identification and the evolution of how we classify kidney diseases. Before the 1960s, many cases were likely grouped under the broader, non-specific diagnosis of "chronic glomerulonephritis." Once Jean Berger characterized the specific pattern of IgA deposits in 1968, the condition became widely known as Berger’s disease. Over time, as our understanding of immunology grew, the descriptive term IgA glomerulonephritis was adopted to emphasize the inflammatory nature of the disease. Today, IgA nephropathy is the standard because it encompasses both the immunological cause and the resulting kidney damage, providing the most clarity for clinicians and the 347 members of the DiseaseMaps community who live with this diagnosis.

What are the historical and regional synonyms for IgA nephropathy?

When reviewing older medical files or international research papers, you may encounter several terms that refer to the same condition. It is important to know that these are not different diseases, but rather historical or descriptive labels for IgA nephropathy:

• Berger’s disease: The most common eponym used in honor of Jean Berger.


• IgA glomerulonephritis: Used frequently in European literature to emphasize the inflammation of the glomeruli.


• Synpharyngitic glomerulonephritis: A descriptive term referring to the onset of hematuria (blood in the urine) shortly after a pharyngeal (throat) infection, which is a classic clinical presentation of IgA nephropathy.


• Focal proliferative glomerulonephritis (with IgA deposits): A descriptive histological term used by pathologists in older biopsy reports.

How can you ensure your medical records reflect the correct diagnosis?

Because multiple terms exist, patients should ensure their medical records are consistent. If your records use different labels, ask your nephrologist to verify that the diagnosis is IgA nephropathy. Having a unified name for your records is essential when consulting different specialists or seeking second opinions. If you are part of the DiseaseMaps community, ensure your profile reflects the standard IgA nephropathy terminology to help researchers and other patients find relevant data more easily.

Next steps

• Confirm your diagnosis with a board-certified nephrologist using the current IgA nephropathy terminology.


• If you have older records using the term "Berger's disease," ask your current provider to add a note confirming it is the same condition.


• Join specialized support groups on DiseaseMaps.org to connect with others who are managing the same diagnosis.


• Request a copy of your pathology report to see if the findings are explicitly documented as IgA nephropathy.
