Clinical Significance: Proteins

Nephrotic syndrome

A kidney disorder characterized by high levels of protein in the urine, low levels of protein in the blood, high cholesterol levels, and swelling.

Proteinuria

Presence of excessive protein in the urine, defined as greater than 3.5 g/dL in nephrotic syndrome.

Hypoalbuminemia

Low levels of albumin in the blood, leading to fluid imbalance and edema.

Edema

Swelling caused by fluid retention in tissues, often associated with hypoalbuminemia.

Hyperlipidemia

High levels of lipids (fats) in the blood, often seen in nephrotic syndrome.

Multiple Myeloma

A type of cancer affecting plasma cells in the bone marrow, characterized by abnormal proliferation and M protein production.

M protein

An abnormal protein produced in excess by myeloma cells, detectable in blood and urine.

Immunodeficiency

A condition where the immune system's ability to fight infections is suppressed, often due to excess M protein in multiple myeloma.

Macroglobulinemia

A rare blood cancer characterized by the overproduction of IgM antibodies, arising from abnormal B lymphocyte proliferation.

Hyperviscosity Syndrome

A condition caused by high levels of IgM in the blood leading to increased blood thickness and circulation problems.

Liver Cirrhosis

A serious condition marked by the replacement of healthy liver tissue with scar tissue due to chronic damage.

Fibrosis Formation

The excessive production of collagen leading to scar tissue formation in the liver.

Elevated Portal Vein Pressure

Increased pressure in the portal vein due to scar tissue, leading to complications such as splenomegaly.

Hepatocellular Dysfunction

Impaired functionality of liver cells, often resulting in hypoalbuminemia and other metabolic issues.
