Brief Summary

The overall goal of the Asthma Inflammation Research \[AIR\] Translational Program is to create an integrated multidisciplinary team for the focused purpose of development of diagnostic and prognostic tests informative for airway inflammation, and for the design of innovative, targeted biologic therapeutics. The overarching aims of the AIR program are to conceptualize, develop, and test the next-generation therapeutics, and novel asthma diagnostic and prognostic tools that will allow us to improve the standard of asthma care.

Outcome Measures

Primary Outcomes (1)

  • Maintaining a tolerance to Medium Chain Triglyceride (MCT) additive for Asthmatics

    Tolerability of the MCT will be assessed by maintenance of use of MCT by 20% or more participants over the 3 months of the study.

    24 weeks

Secondary Outcomes (4)

  • Improvement of lung function by spirometry testing

    24 weeks

  • Asthma Quality of Life Questionnaire

    24 weeks

  • Asthma Control Test

    24 weeks

  • Gastrointestinal tolerance of a Medium Chain Triglyceride additive to a normal diet in Asthmatics

    12

Study Arms (4)

Nutritional Approach for Asthma

ACTIVE COMPARATOR

individuals will be provide a pre measured dose of medium chain triglyceride to consume along with their meals. They will be instructed to add the MCT to their meal 3 times per day

Dietary Supplement: Nutritional approach for asthma

Standard American Diet

PLACEBO COMPARATOR

patients will consume their usual diet with a pre measured dose of canola oil in place of the medium chain triglyceride as a control group. They will be instructed to add the placebo dose to their meal 3 times a day

Dietary Supplement: Nutritional approach for asthma

Alternate Day Diet

ACTIVE COMPARATOR

patients will consume a regular "Standard American Diet" for 4 weeks and then provided a regulated dosed quantity of low caloric value "shakes". they will consume this on alternating days

Dietary Supplement: Low Caloric Shake

Whole Lung Allergen Challenge

ACTIVE COMPARATOR

patients with or without asthma will be given controlled doses of specified allergens

Biological: whole lung allergen challenge

Interventions

participants will be provided a medium chain triglyceride supplement or placebo

Also known as: MCT supplement
Nutritional Approach for AsthmaStandard American Diet
Low Caloric ShakeDIETARY_SUPPLEMENT

participants will be provided a low caloric dietary shake

Alternate Day Diet

inhalation of allergens by allergic patients with or without asthma, will be used to define mechanisms underlying the development of airway inflammation

Whole Lung Allergen Challenge
