A 2011 systematic review did not identify any randomized trials of therapies for treating pulmonary exacerbations in cystic fibrosis patient chronically infected with B. cepaciacomplex, concluding that clinicians must continue to assess each patient individually, taking into consideration in vitrosusceptibility results, previous clinical response, and clinical experience (73). Typical therapy for exacerbations associated with B. cepacia complex includes 14-21 days of parenteral therapy with at least two antimicrobials, intensified chest physiotherapy to promote airway clearance, and bronchodilator administration (60).

Burkholderia cepacia is an aerobic gram-negative bacillus found in various aquatic environments. Despite in vitro susceptibility, antimicrobial agents are very ineffective in eradicating chronic B. cepacia complex pulmonary infection from patients with cystic fibrosis (62). This discrepancy between in vitro susceptibility and the clinical response may be due to a variety of factors in cystic fibrosis patients including: altered pharmacokinetics, failure to deliver drug to the bronchiectatic lung, failure to penetrate across the bronchial mucosa in sufficient concentration into abnormally viscous bronchial secretions, high colony counts of organisms (>107 cfu/mL), biofilm resistance, and local factors such as decreased pH and increased concentration of divalent cations that impair phagocytic activity in the lung.

Historically regarded as an organism of low pathogenicity, B. cepacia complex can be transmitted person to person in both healthcare and non-healthcare settings, and both direct and indirect contact with infectious secretions and droplet spread have been implicated in transmission (25, 31, 32, 39, 63). B. cepacia complex can survive for long periods in water or disinfectants, and healthcare-associated outbreaks of B. cepacia complex infection have been linked to contaminated nebulized and intravenous medications and solutions, including compounded and commercially distributed products, skin care products, disinfectants, and to inadequate disinfection of reusable medical devices (20, 47, 49, 58).
