MPO and triple-A syndrome: This parameter correlated positively with NGAL and neutrophil elastase in AAA walls underlying thick ILT (r = 0.43, p = 0.011; r = 0.39, p = 0.017, respectively) and thick thrombus (r = 0.40, p = 0.018; r = 0.38, p = 0.024, respectively), as well as with MPO within AAA walls underlying thick ILT (r = 0.58, p = 0.0002).
