Usefulness of a prognostic inflammatory and nutritional index in pediatric clinical practice
Insights
The prognostic inflammatory and nutritional index (PINI) effectively assesses pediatric health, combining infection and malnutrition markers. This sensitive tool aids in early detection of complications and treatment monitoring in children.
Area of Science:
- Pediatric Medicine
- Biochemistry
- Clinical Diagnostics
Background:
- Inflammation and malnutrition are critical factors in pediatric disease severity.
- Accurate assessment of both inflammatory and nutritional status is essential for effective patient management.
- Existing diagnostic tools may not comprehensively address both aspects simultaneously.
Purpose of the Study:
- To evaluate the clinical utility of the prognostic inflammatory and nutritional index (PINI) in hospitalized children.
- To determine if PINI can serve as a sensitive and universal tool for monitoring disease progression.
- To assess PINI's value in identifying subclinical complications and therapeutic efficacy in pediatric patients.
Main Methods:
- The study involved 47 hospitalized infants and 72 age-matched healthy controls.
- The PINI formula was calculated using markers for infection (C-reactive protein, orosomucoid) and malnutrition (albumin, transthyretin).
- A micromethod requiring only 46 microliters of serum was utilized for rapid and repeatable measurements.
Main Results:
- A PINI value less than 1 indicated healthy children, while values above 1 correlated with worsening illness.
- The PINI scoring system demonstrated sensitivity in distinguishing between healthy and sick pediatric patients.
- The index proved helpful in recognizing early subclinical complications and evaluating treatment effectiveness.
Conclusions:
- The PINI is a valuable and universal tool for clinicians managing pediatric patients.
- It allows for the effective follow-up of both inflammatory and nutritional parameters in disease.
- The PINI facilitates early detection of complications and assessment of therapeutic strategies in pediatric practice.
Abstract:
The clinical usefulness of a prognostic inflammatory and nutritional index (PINI) was evaluated in 47 hospitalized infants and 72 age-matched controls from 1 mth to 14 yr of age. The PINI formula is a combination of two markers each of infection (C-reactive protein and orosomucoid) and of malnutrition (albumin and transthyretin). Healthy children are identified by a PINI value less than 1 whereas sick patients are characterized by a progressive rise above 1 as the conditions worsens. The PINI scoring system provides the clinician with a sensitive and universal tool, allowing the correct follow-up of both inflammatory and nutritional poles of the disease spectrum. The formula is of particular help in pediatric practice in recognising early subclinical complications and efficacy of specific therapeutic strategies. The micromethod is simple, rapid and may be regularly repeated since it requires only 46 microliters of serum.
