n
=
57
) and healthy controls (
n
=
19
) and if their expression levels are related to selected clinical parameters. The group of 26 patients [AdipoR(−)] showed lower and the group of 31 patients [AdipoR(+)] showed higher AdipoRs protein expression than the control and each other (
P
<
0.01
for neutrophils,
P
<
0.05
for monocytes). The AdipoR(+) leukocytes expressed higher AdipoR1 mRNA levels (RT-PCR) than AdipoR(−) ones and controls (
P
=
0.022
and
P
=
0.007
, resp.). Despite greater BMI, the AdipoR(−) patients had unchanged serum adiponectin levels. In contrast, AdipoR(+) patients had lower serum adiponectin concentrations than the AdipoR(−) ones and controls (
P
<
0.001
). The AdipoR(+) patients had higher blood pressure (
P
=
0.042
)和颈动脉内膜中层厚度大(
P
=
0.017
) than the AdipoR(−) ones. The stage of hypertension was associated with increased neutrophil but not monocyte AdipoR1 density (AdipoR1 MFI) (
P
<
0.05
). Severe ambulatory hypertension was presented more often in AdipoR(+) patients than in AdipoR(−) ones (51.6% versus 26.9%, resp.;
P
<
0.01
). In conclusion, neutrophil AdipoRs upregulation was associated with early stages of vascular injury, hypertension severity, and low serum levels of adiponectin.
