Which condition is associated with high protein levels?

Amyloidosis is indeed associated with high protein levels, specifically due to the abnormal accumulation of amyloid proteins in various tissues and organs. In this condition, a protein misfolding disorder occurs, which leads to the deposition of amyloid fibrils. These deposits can be found in several organs, disrupting their normal function. The protein levels can be significantly elevated in serum, which can be detected through specific laboratory tests.

Kwashiorkor, marasmus, and malnutrition typically involve low protein levels because these conditions are primarily characterized by inadequate nutritional intake. Kwashiorkor, for example, results from a deficiency of dietary protein despite normal caloric intake and is marked by low serum albumin levels. Marasmus, on the other hand, is a form of severe malnutrition resulting from a significant deficiency in caloric intake, leading to muscle wasting and low protein levels as well. Thus, in contrast to amyloidosis, the other options reflect conditions where protein levels are not elevated, but rather diminished or deficient due to lack of nutritional resources.
