Overview

Protein losing enteropathy is the loss of plasma proteins from the gastrointestinal tract caused by an array of abnormalities, such as primary gastrointestinal diseases and lymphatic obstruction. Protein losing enteropathy is not a separate disease entity but a complication of different pathological conditions leading to hypoproteinemia. Treatment is tailored towards the underlying etiology leading to protein losing enteropathy as a complication.

Historical Perspective

  • There is no historical significance associated with protein losing enteropathy.

Classification

  • There is no classification for protein losing enteropathy according to recent updates.

Pathophysiology

Normally there is a balance between the synthesis and degradation of proteins maintained by a series of interconnected processes in the body. Any condition which disrupts the normal protein stasis where the loss of protein through the gastrointestinal tract exceeds the body’s ability to synthesize proteins failing to compensate for the loss leads to the development of a state of low serum protein called hypoproteinemia.[1][2] [3]

Causes

Most cases of protein losing enteropathy are caused as a result of:

  1. Primary gastrointestinal diseases
  2. Lymphatic obstruction

Primary Gastrointestinal Diseases

Mucosal Erosions/Ulcerations

Primary gastrointestinal diseases causing erosion or ulceration of the mucosa of the gut leading to fecal loss of proteins such as:[1][5][6]

Non-Erosive/Ulcerative Mucosal involvement

Lymphatic Obstruction

Conditions responsible for causing lymphatic obstruction leading to the leakage of lymph into the lumen of gut such as:

Complete Differential Diagnosis Of Underlying Causes

Protein losing enteropathy must be differentiated from any condition causing hypoproteinemia. Some common condition are listed below:[11] [12] [13] [14] [15]

Diagnosis

As hypoproteinemia is the key factor in evaluating a patient for protein losing enteropathy, other common causes of hypoproteinemia such as nephrotic syndrome, impaired protein synthesis due to chronic liver disease and malnutrition must be excluded first.[16]

Laboratory Studies

As the most prominent laboratory finding is a decrease in serum concentration of albumin and globulin, the diagnostic work up protein losing enteropathy consist of quantitative measurements of Alpha-1 antitrypsin or 51Cr-albumin.[17]

  • Alpha 1-AT plasma concentration = ((stool volume) x (stool alpha 1-AT)) / (serum alpha-1 AT)
  • 51Cr-labeled albumin can also be measured followed by stool collection to determine the amount of protein loss into the gastrointestinal tract.

Imaging Studies

Following the detection of abnormal amounts of alpha-1 antitrypsin in the stool, the following tests can be performed to detect the specific etiology for the protein loss into the gastrointestinal lumen.[17]

Other tests:

Treatment

  • Symptomatic relief can be achieved with dietary modifications and medications.
  • However, protein losing enteropathy is not a separate disease entity but a complication of different pathological conditions and hence the mainstay of treatment depends upon the underlying etiology of the disease causing protein losing enteropathy.
