The Effect of Cow Milk Consumption on Respiratory Symptoms and Pulmonary Functions in Asthmatic and Non Asthmatic Children

May 1, 2016 updated by: Tel-Aviv Sourasky Medical Center

The Effect of Cow-milk Consumption on Respiratory Symptoms and Pulmonary Functions in Asthmatic and Non-asthmatic Children

the investigators hypothesis is that milk consumption, either in the acute phase and through prolonged exposure, does not cause or increase respiratory symptoms or airway inflammation. the investigators aim to objectively prove this by examining respiratory symptoms and signs and objectively measuring parameters of airway inflammation and hyper responsiveness after consumption of cow milk or soy milk substitute.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Unknown

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this prospective single blinded placebo controlled trial, acute milk consumption will be evaluated. 50 asthmatic and 50 healthy children aged 6-18 will drink 240 ml of cow milk or soy milk substitute. Respiratory symptoms by questionnaire and physical examination will be evaluated. Airway response and inflammation will be assessed by fraction of exhaled Nitric Oxide (FENO) and spirometry before and after the exposure.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame

Time Frame: Baseline

single breath method: This test measures the concentration of NO in the exhaled air. In this method the patient takes a deep breath from the filter device and exhales the air at a constant rate of 50 mL / min for 12 seconds. The results of each test will be the average value of three tests.

General measurement: overall system to be measured FENO device Denox 88 (ECO Medics AG, Switzerland), and nitric oxide 88 CLD analyzer which was approved for use by the FDA's medical device approval if the Ministry of Health. The values are in parts per billion (Ppb).

children aged 5-6 years are able to perform this test.

FENO values:

Spirometry - Forced expiratory flow 1 sec
Time Frame: Baseline
This test measures how much air is moved in and out of the lungs and how fast the air moves. the patient will be asked to take in a deep breath and to blow the air out into a filter that is connected to a computer. computer measures how much and how fast the air is blown out. Each test will be performed three times and the average value choice.Forced expiratory flow 1 sec (percent of predicted value) is the value that will be compared before and after the intervention.
