3.2 | Plasma PAF-AH activity
The distributions of PAF-AH activity in the study group and the control
group were presented in figure 1. They differed substantially, which was
reflected in the highly statistically significant difference in the
arithmetic means in both groups.
As shown in figure 2, no significant differences were found in the
arithmetic mean values of plasma PAF-AH activity in the individual
degrees of severity of anaphylaxis (p > 0.05). Although,
these values were considerably lower than the value in the control
group, which was 21.38 ± 9.50 nmol/min/ml (p < 0.0001).
According to table 2, the arithmetic mean values of plasma PAF-AH
activity in the subgroup I-II (9.47 ± 1.87 nmol / min / ml) and in the
subgroup III-IV (10.16 ± 2.50 nmol/min/ml) also did not differ
significantly (p > 0.05), but were substantially lower as
compared to the value in the control group (p < 0.0001).
The arithmetic mean values of plasma PAF-AH activity in the smokers
and non-smokers did not differ significantly (9.46 ± 1.95 nmol/min/ml vs
10.13 ± 1.61 nmol/min/ml, p = 0.201).
There was no statistically significant correlation between the plasma
PAF-AH activity and most of the parameters, including the age of the
patients (r = -0.035). There was only a statistically significant, but
clinically irrelevant, correlation with tryptase concentration (r =
0.21).
