Abstract |
There have been very few studies on serum biomarkers associated with hypertension in disaster situations. We assessed biomarkers associated with disaster-related hypertension (DRH) due to the Great East Japan Earthquake of March 2011.We collected blood samples from members of the Japan Self Defense Forces (JSDF) (n = 77) after completing disaster relief operations. We divided them into two groups based on systolic blood pressure. We defined DRH as either systolic blood pressure greater than 140 mmHg or diastolic blood pressure greater than 90 mmHg at the time of completing missions.In subjects with DRH, the mean blood pressure was 143.5 ± 5.0/99.5 ± 2.4 mmHg. Height and body weight measurements were slightly greater in the DRH group but the differences were not significant, and age was significantly higher in the DRH group. There were no differences in serum biochemical tests including metabolic markers, sulfur-containing amino acids, and cytokines. Among nitric oxide-related amino acids, asymmetric dimethylarginine (ADMA) was lower in the DRH group than in the normotension group (0.40 ± 0.02 versus 0.31 ± 0.02 μmol/L P = 0.04). The serum oxidative stress metabolite levels (d-ROMs; indicators of active oxygen metabolite products) were significantly higher in the DRH group (273.6 ± 6.08 versus 313.5 ± 13.7 U.CARR P = 0.016). Using multivariable regression analysis, d-ROMs levels were particularly predictive for DRH.Oxidative stress is associated with DRH in responders to the disaster of the Great East Japan Earthquake.
