Phase Angle and its Association with Inflammatory Markers

Anthropometric Assessment

Anthropometric measurement plays a principal role in the patient’s health assessment. Anthropometric measures are an essential part of our clinical findings; body composition analysis provides vital information about our nutritional status. Our body is our vehicle, and as such, it serves as a storage for our energy in the form of fat deposits and muscle mass. Our body comprises other compartments such as intracellular and extracellular water, bone mass, and vital organ mass in addition to muscle and fat tissue. Multiple measurements like body mass index (BMI), body fat percentage (BFP), and lean muscle mass (LMM) associate with many conditions and provide additional insight into their medical and nutritional treatments. Furthermore, the standardized phase angle (SPhA) is a tool that can measure membrane integrity and can predict survival in malignancies and hematopoeitic stem cell transplant patients.

Body Composition

Body composition is measure in many forms and levels throughout the years. Nowadays, bioelectrical impedance analysis (BIA) provides an indirect estimate of our body composition by measuring the impedance a specific tissue (fat, muscle, and bone) exerts against an electric current. 

 

Phase angle (SPhA)

The standardized phase angle (SPhA) is, by definition, the ratio of resistance to the reactance. Therefore, it is a measure of how intracellular and extracellular resistance resists the cell membrane-specific resistance, becoming a marker of cellular vitality and integrity. Recent studies consider that SPhA is an essential tool for nutritional assessment and is a highly predictive index of clinical impairments and diseases. Also, SPhA positively correlates with lean body mass. On the other hand, an elevated extracellular-to-intracellular fluid ratio inversely correlates to SPhA.

Average SPhA values correlate to a preserved cellular activity and may reflect a rapid recovery after surgery/injury. Nonetheless, this marker represents a predictive measurement in disease-related malnutrition, sarcopenia, and CVD.

Furthermore, the inverse relation between elevated ECW/ICW ratio and SPhA makes it a better malnutrition predictor. Indeed, an elevation ECW/ICW ratio relates to decreased body cell mass and malnutrition. Furthermore, malnutrition is commonly characterized by low pre-albumin and albumin levels and low scores in nutritional assessment questionnaires like the subjective global assessment (SGA) and the nutrition risk score in ICU patients.

SPhA clinical applications

A study was performed to prove the SPhA effectiveness as a marker of sarcopenia, cachexia, and malnutrition in 412 hospitalized patients with CVD. This study compared SPhA with various biochemical markers, as well as intrahospital nutritional and strength screening tools. 

CONUT

This study used the nutritional screening tool CONUT that stands for CONtrolling NUTritional status. Conversely, this screening test considers laboratory information, including serum albumin, total cholesterol level, and total lymphocyte count. CONUT is as practical as the Subjective Nutritional Assessment (SGA) to diagnose undernutrition in hospitalized patients, is predictive of the length of intrahospital stay, and assesses immune status. Furthermore, this study concludes that a normal range SPhA can positively relate to the CONUT scores and hemoglobin and albumin levels.

 

CRP

C- reactive protein is an inflammatory marker produced by our liver and released to the circulatory system in the presence of infection, chronic diseases, or inflammatory responses. However, in nutritional assessment, a CRP level over 5mg can be indicative of cachexia. Besides this, CRP can be used in combination with SPhA to detect malnutrition, cachexia and be reflective of a prolonged intrahospital stay.

 

SPhA is a novel marker with a wide array of clinical applications. Despite being a multifaceted marker, it provides specific measurements to determine whether the patient has a good prognosis. Also, it is a safe and rapid way to assess health status because BIA can easily measure it. However, SPhA’s applications need to be studied in depth to determine further uses, but it is a promising new perspective.

Nutritional assessment has multiple components. Therefore, the integration of a specialized marker as PhA shed new light ta an element that was difficult to assess with anthropometric measurement. This anthropometric marker’s association to the cellular membrane status and permeability can alleviate the necessities needed in multiple clinical areas. Also, the fact that a BIA device can allow us to have that insight means that we could prevent further complications. – Ana Paola Rodríguez Arciniega, MS.
