An Evaluation of Nutritional Status, Body Composition, and Dietary Intakes of Filipino Pediatric Patients With Inborn Errors of Intermediary Protein Metabolism (Project SIBS)

28. september 2026 opdateret af: Jason Paolo H. Labrador, Food and Nutrition Research Institute, Philippines

In the Philippines, a disease is considered rare if it affects one in every 20,000 individuals. About 75% of rare diseases in the country, including inborn errors of intermediary protein metabolism (IEIPM), are of genetic in origin with symptoms beginning in early infancy with about 30 percent of patients dying before the age of five. Diagnosing nutritional problems in pediatrics with IEIPM is challenging due to the potential absence or masking of early signs and symptoms. Nutrition care is more difficult to manage since dietary modification for these patients require extraordinary and diligent attention as an uncontrolled or poorly managed diet can lead to severe health conditions. Its detrimental effects are irreversible and might last until adulthood affecting the overall quality of life and well-being of the child and increasing the burden on parents and families. Hence, there is a compelling impetus to gain further understanding on these aspects, particularly at the earliest stages of growth and development. However, previous studies in the Philippines that have specifically focused on the nutritional needs of pediatric patients with IEIPM are scarce. Therefore, this underscores the imperative need to carry out thorough evaluation of the nutritional characteristics of Filipino neonates, infants, children, and adolescents who have been diagnosed with IEIPM.

This study will provide information on nutritional status among pediatric patients with IEIPM in the local setting. The results will form a potential basis for incorporating rare diseases in the comprehensive nutrition program at the local government units focusing on the targeted special needs of this vulnerable group. The data on the dietary intakes will provide clinicians a better picture of the overall nutritional intake and the specific nutrients that may be lacking for optimal growth and development of infants and children under a restricted special diet. Moreover, this may also provide an opportunity to evaluate the adapted nutritional management guidelines being implemented in the continuity clinics in the country. Lastlly, the knowledge that will be generated will lead to a better understanding of the relationship between nutritional status, body composition, dietary intake, and some of the important biochemical and clinical outcomes that can guide the development of appropriate nutrition policies, guidelines tailored to fit the Filipino pediatric population with IEIPM. This study on IEIPM which covers amino acid disorders, organic acidemias, and urea cycle defects, recognizes the crucial role of research in defining health programs and activities for these rare conditions in support of the Republic Act no. 10747, also known as the Rare Diseases Act of the Philippines.

Detaljeret beskrivelse

The general objective of the study is to evaluate the nutritional status, growth, body composition, selected biochemical and clinical parameters, and dietary intakes of Filipino pediatric patients, aged 0 months-18 years old, diagnosed with Inborn Errors of Intermediary Protein Metabolism (IEIPM) who are receiving medical and dietary treatment. Specifically, the study aims to:

  1. To compare the changes in nutritional status, body composition, dietary intake, selected biochemical, clinical parameters such as medical history and clinical presentations, anthropometric parameters such as height/length, weight and head circumference of pediatric patients diagnosed with IEIPM versus their age- and sex-matched healthy controls from baseline (month 0) to endline (month 12) assessment;
  2. To assess the adequacy and distribution of energy, macro-and micronutrient intake from natural food, medical food, and combination of natural and medical food consumption of pediatric patients diagnosed with IEIPM from baseline (month 0) to endline (month 12) assessment;
  3. To determine the association between nutritional status and body composition with dietary intakes, selected biochemical and clinical parameters;
  4. To determine a safe protein-energy ratio (P:E ratio) associated with optimal nutritional status, growth, and body composition among Filipino pediatric patients with IEIPM; and
  5. To determine caregivers' experiences, perceptions, and practices related to the dietary management of Maple Syrup Urine Disease (MSUD).

Tidsramme
Weight (in kilograms) and age (in years and months) will be combined to report Weight-for-Age in Z-score
Tidsramme: Month 0 (Baseline), Month 6 (Midline), and Month 12 (Endline)

Weight will be measured using a digital baby weighing scale (SECA 354) for children younger than 2 years of age and a double-window digital weighing scale (SECA 874) for children older than 2 years of age. This indicator will be used in children aged 0-10 years. The z-scores will be obtained using the World Health Organization (WHO) Child Growth Standards 2006 and Growth Reference 2007 to determine if the child is normal (-2SD to +2SD), underweight (<-2SD), or severely underweight (<-3SD).

Height/length will be measured using an infantometer (SECA 416/417) for children younger than 2 years of age and a stadiometer (SECA 213 I) for children older than 2 years of age. The z-scores will be obtained using the WHO Child Growth Standards 2006 and Growth Reference 2007 to determine if the child is normal (-2SD to +2SD), stunted (<-2SD), or severely stunted (<-3SD).

For children aged 10 and below, non-fasting samples are extracted, and results showing concentrations below 65 µg/dL (AM) and 57 µg/dL (PM) are considered deficient. For females aged more than 10 years, results showing concentrations of zinc in the fasting sample below 70 µg/dL and in the non-fasting sample with results below 66 µg/dL(AM) and 59 µg/dL (PM) are considered deficient. For males aged more than 10 years, results showing concentrations of zinc in fasting samples below 74 µg/dL, non-fasting samples with results below 70 µg/dL(AM), and 61 µg/dL (PM) are considered deficient.

Overall Risk of Malnutrition
Tidsramme: Month 0 (Baseline), Month 6 (Midline), and Month 12 (Endline)

The overall risk of malnutrition will be evaluated using the Pediatric Subjective Global Nutritional Assessment (PSGNA) Form. The PSGNA is used to subjectively assess the nutritional status of children who may be at risk of malnutrition through a nutrition-focused physical exam. Loss of subcutaneous fat will be checked in the orbital, buccal area, upper arm, ribs/midaxillary, and buttocks. Loss of muscle mass in the temple region, clavicle bone, acromion bone, scapular bone and spine regions, anterior thigh, patellar, and calf will be assessed. Lastly, the presence of edema will also be evaluated in the foot, ankles, and sacral area. The classification to determine the risk of malnutrition is as follows:

  • Normal/Well-nourished: No loss of subcutaneous fat and muscle mass, and no edema
  • Moderate risk: Loss of subcutaneous fat and muscle mass is observed in at least one area, and/or with edema
  • Severe risk: Loss of subcutaneous fat and muscle mass is observed in more than one area,
