Patients’ FEV1 and BMI values were restrospectively collected for the 6 months pre and post aztreonam lysine and mean values were calculated. The total number of IV antibiotic days pre and post were also collected.
Data for 27 patients (9 males) was collected, mean (SD) age 34.0 (11.5) years range 19 to 71 years. From the 27 patients trialled 1 patient failed the trial, 1 patient discontinued, 4 patients were transplanted and 1 patient died awaiting a transplant.
Aztreonam lysine was well tolerated within the adult population at the AWACFC. The majority of patients commenced on aztreonam lysine generally had severe lung disease and 4 of these went on to have transplants. This is likely to account for the lack of statistical significance for mean FEV1 and BMI change. However it is reassuring that these patients appeared stable over a 6 month period. There was a statistically significant reduction in the number of post IV antibiotic days. The study is limited by the small number of patients included in the data and should be analysed in conjunction with a larger database.
