Effect of Chromium Weight Reduction on Adult Asthma Control

This phase IV randomized controlled trial is designed to evaluate the effects of chromium picolinate supplementation in obese adults with stable asthma. A total of 60 participants will be recruited from Ain Shams University Hospitals and randomly assigned to receive either 400 mcg of chromium picolinate daily or a matching placebo for 12 weeks, in addition to standard asthma therapy.

The study aims to explore the interaction between metabolic dysfunction and asthma, as obesity-related asthma is often associated with systemic inflammation, insulin resistance, and dyslipidemia. These factors may contribute to poorer asthma control and impaired pulmonary function, and therefore represent potential targets for adjunctive therapeutic interventions such as chromium supplementation.
