The explorative blood parameters C3a and LTB4 showed a moderate but statistically non-significant elevation of median levels among the AAA patient group compared to the healthy control group with C3a: 16.5 μg/ml (IQR = 12.5 μg/ml) vs. 14.3 μg/ml (IQR = 9.1 μg/ml), p = 0.156 and LTB4: 30.6 pg/ml (IQR = 33.6 pg/ml) vs. 27.5 pg/ml (IQR = 18.8 pg/ml), p = 0.803 (Fig. 1a, b). This evidence concerns the gene C3 and triple-A syndrome.
