We postulated that accumulation of adipose tissue within the airway wall may occur in overweight patients and contribute to airway pathology.

The relationship between airway adipose tissue, remodelling and inflammation was assessed. The areas of the airway wall and adipose tissue were estimated by point count and expressed as area per mm of basement membrane perimeter (Pbm).

Adipose tissue was identified in the outer wall of large airways (Pbm &gt;6\u2005mm), but was rarely seen in small airways (Pbm &lt;6\u2005mm). Adipose tissue area correlated positively with eosinophils and neutrophils in fatal asthma (Pbm &gt;12\u2005mm, p&lt;0.01), and with neutrophils in control subjects (Pbm &gt;6 mm, p=0.04).\n                  <\/jats:p>\n                  <jats:p>These data show that adipose tissue is present within the airway wall and is related to BMI, wall thickness and the number of inflammatory cells.
