BRONCHIECTASIS
DEFINITION
Permanent dilatation of one or more bronchi
Elastic and muscular tissue of bronchial walls destroyed by
acute and chronic infection
Impaired drainage of secretions
Secretions chronically infected
Chronic inflammatory response
Progressive destructive lung disease
BRONCHIECTASIS
COMMON CAUSES
Common causes of Bronchiectasis
Post-infective
Tuberculosis
Measles
Whooping cough
Mucociliary clearance defect
CF
PCD
Young’s syndrome
Immune defects
Immunoglobulin deficiency
Cellular defects
ABPA

CLINICAL FEATURES
Totally asymptomatic to severe disease
 Productive cough with large amounts of purulent
secretions, sometimes haemoptysis
 Frequently admitted to hospital

CF (CONTINUED)
Abnormality in protein (CFTR)
Changes in ion transport
Changes in mucus and serous secretions produced by
exocrine glands, respiratory system and digestive tract
CF (CONTINUED)

Ion transport → absorption of sodium ions
from mucosal surface → movement of water
into epithelial cells.

Balance between movement of sodium and
chloride → volume and composition of of
airway surface liquid and mucociliary clearance

DIAGNOSIS AN PRESENTATION
Newborn screening

(malabsorption and hyposecretion of enzymes
by pancreas)
