ABSTRACT
Objective: To discover the frequency and presence of multiple antimicrobial resistant strains of Pseudomonas aeruginosa [P.aeruginosa] in patients with Post tuberculosis bronchiectasis in Baluchistan
Design: A prospective descriptive study
Place and duration: this study was done in Pulmonology and tuberculosis outpatient department [OPD] of Fatimah Jinnah Chest Hospital and Rehan Hospital Quetta Pakistan from 1st October 2011 to 1st April 2012
Methodology: The samples were obtained from post tuberculosis patients [n=60, Age = 40+ years] suspected of bronchiectasis who were subjected to spirometry test, Mueller Hinton sensitivity testing, oxidase test and disk-diffusion method to find out frequency and multiple drug resistance of P. aeruginosa
Results: Our results confirmed the association of chronic P. aeruginosa infection with poor lung function. It is not clear whether P. aeruginosa caused the accelerated decline in lung function or it was just a marker of those whose lung function was already declining rapidly. The antibiotic susceptibility testing confirmed the presence of resistant strains of the P. aeruginosa most of which were mucoid strains. It proved that a single antibiotic therapy is not a good treatment for patients with P. aeruginosa infection in airways
Conclusion: Bronchiectasis is more frequently encountered in middle-aged and elderly persons and resistant strains of P. aeruginosa are highly prevalent in these patients
