Exclusively in patients with asthma and history of atopic disorder

5

Typical presentation of ABPA?

Asthmatic patient with recurrent episodes of brown-flecked sputum and transient infiltrates on x-ray

#Cough, wheezing, hemoptysis and sometimes bronchiectasis

6

Diagnostic tests for ABPA?

#Peripheral eosinophilia
#skin test reactivity to Aspergillus
#Aspergillus anti-bodies
#Elevated IGE
#infiltrates in imaging

7

Treatment of ABPA?

# Pancreas (steatorrhea, ADEK deficiencies, recurrent pancreatitis)
#liver (biliary cirrhosis)
#Intestines (obstructions, meconium ileus as child)
#GU tract (azoospermia, infertility, missing vas deferens)

9

Presentation cystic fibrosis?

#Young adults with chronic lung disease
#Recurrent infection
#Sinus pain/nasal polyps

10

Diagnostic test for CF?

Increased sweat chlorine test (over 60 mEq/L) > genotyping

11

PFT in CF?

#Mixed obstructive and restrictive pattern
#Decrease in FVC and TLC
#Decreased Diffusion capacity

12

Treatment for CF?

#Antibiotics based on sputum culture (inhaled aminoglycosides)
#Inhaled recombinant human deoxyribonuclease (breaks down DNA in mucus clogging airways)
#Inhaled bronchodilators
#Pneumococcal/influenza vaccination
#transplant
