NCT05728385

Brief Summary

The aim of this study will explore if the specific carbohydrate diet has an effect on asthma control in children and if it will affect the frequency, severity, and duration of asthma and thus provide it as a potential complementary treatment option for them.

Outcome Measures

Primary Outcomes (1)

  • Childhood-asthma control test (C-ACT) as a subjective method

    The C-ACT consists of a 7-item validated questionnaire, addresses the previous 4 weeks and is divided into two parts. One part is filled in by the child and consists of four questions on perception of asthma control, limitation of activities, coughing and awakenings at night. Each question has four response options. The second part is filled in by the parent or caregiver and consists of three questions (daytime complaints, daytime wheezing and awakenings at night) with six response options. The sum of all scores yields the C-ACT score, ranging from 0 (poorest asthma control) to 27 (optimal asthma control). A cut-off point ≤ 19indicates uncontrolled asthma

    Baseline (three months)

Secondary Outcomes (3)

  • FEV1

    three months

  • FVC

    three months

  • FEV1/FVC ratio

    three months

Study Arms (2)

Modified SPD as adjunct to asthma medications in children

EXPERIMENTAL

Explore if the modified specific carbohydrate diet has an effect on asthma control in children and if it will affect the frequency, severity, and duration of asthma and thus provide it as a potential complementary treatment option for them.

Dietary Supplement: Modified Specific carbohydrate diet for 3 months

Usual asthma medications only in children with moderate asthma

NO INTERVENTION

Assess control based on the usual asthma medications only

Interventions

All children at the start of the study will be subjected to: 1. Full history taking including demographic and medical history 2. Full nutritional assessment including: Through clinical examination for any signs of vitamins and mineral deficiency, with full chest examination. 3. Laboratory tests: Complete blood picture with differential white blood cells, and Serum IgE level 4. At the beginning of the study and at the end 1. The patients will be assessed using the childhood-asthma control test (C-ACT) as a subjective method 2. Pulmonary function tests will be performed using spirometry (Spirostik, Geratherm) that includes Forced vital capacity (FVC), forced expiratory volume in the first second of FVC (FEV1), and FEV1/FVC. 3. Anthropometric measurements: Weight, Height, and Body mass index (BMI). All measures will be plotted on specific percentile curves for age and Z score

Modified SPD as adjunct to asthma medications in children

Eligibility Criteria

Age6 Years - 18 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64)

You may qualify if:

  • Asthmatic children with moderate persistent asthma according to the definition of National Heart, Lung, and Blood Institute guidelines, if they have daily symptoms, nighttime awakenings more than 1 time/week, but not nightly, daily use of short-acting beta-agonist for symptom control, some limitations of normal activities, and Forced Expiratory Volume in 1 second (FEV1)60-80%.
  • Children aged from 6 to 18 years.
  • The children are included only if parents and children are strongly motivated to try a dietary intervention (mSCD) as a complementary treatment.

You may not qualify if:

  • Children with chronic lung disease, immunodeficiency, major thoracic deformities, neuromuscular, cardiovascular, digestive, rheumatic, osteoarticular, or genetic syndromes or any adverse health conditions that can affect nutritional status were excluded from the study.
  • Children excluded if parents and children are not motivated to try a dietary intervention (mSCD) as a complementary treatment or who failed to have regular outpatient follow-up visits.
