ABSTRACT
diseases. On the other hand, hypertension is related with excess angiotensin II which would lead to oxidative stress. In this study, we investigated the correlation between F2-Isoprostane (as marker of oxidative stress) with Stromal Cell-Derived Factor-1 (SDF-1) and CD34 viable in non hypertension and hypertension subjects. Methods This was a cross sectional study conducted on 54 nonhypertension and 64 hypertension subjects visiting Prodia laboratory, Jakarta. F2-Isoprostane (as marker of oxidative stress) and SDF-1 (a strmal cell growth factor) were measured by ELISA method, and CD34 viable (marker of progenitor cell) was measured by fl ow cytometry. Results F2-Isoprostane concentration was higher in hypertensive subjects compared to nonhypertensive subjects, although statistically non signifi ant (mean + SD: 0.13 ± 0.120 vs 0.10 ± 0.16; ρg/mL; p = 0.091). SDF-1 concentration was signifi cantly higher in hypertensive subjects compare to nonhypertensive subjects (2821.63 ± 281.94 vs 2623.04 ± 356.28 ρg/mL; P < 0.05). CD34 viable level was signifi cantly lower in hypertensive subjects compare to nonhypertensive subjects (1.9 ± 0.9 /μL vs 2.7 ± 1.7; P < 0.05). F2-Isoprostane had negative correlation with CD34 viable in circulation (r = 0.022, p < 0.05) but no correlation with SDF-1 (p > 0.05). Conclusions F2-Isoprostane was higher, but CD34 was lower, in hypertensive subjects compared to nonhypertensive. It seems that high F2-Isoprostane impaired the CD34 viable level as shown by negative correlation between F2- Isoprostane and CD34.

Aim to assess the differences between Atherogenic Index of Plasma (AIP), ratio of oxidized-Low Density Lipoprotein (Ox- LDL)/High Density Lipoprotein (HDL) and ratio of Lipoprotein-associated Phospholipase A2 (Lp-PLA2)/HDL in predicting the risk of coronary heart disease (CHD) in patients with controlled and uncontrolled type 2 Diabetes Mellitus (T2DM). Methods The study was done observationally with cross sectional design. A total of 80 patients, consisted of 40 controlled and 40 uncontrolled T2DM. The serum triglyceride (TG), HDL-C, Ox-LDL, Lp-PLA2 were examined in their relationship with T2DM risk. AIP is a ratio calculated as log (TG/HDL-C). Results AIP and ratio of Ox-LDL/HDL were signifi cantly higher in uncontrolled than controlled T2DM (0.72 + 0.13 vs 0.47 ± 0.22 , p < 0.001) and (1738.8 ± 625.5 vs 1418 ± 535.3, p = 0.02), but no signifi cant difference was found in ratio of Lp-PLA2/HDL (5.09 ± 2.17 vs 5.95 ± 3.11, p = 0.16). Conclusion AIP and ratio of Ox-LDL/HDL value were signifi cantly higher in uncontrolled than in controlled T2DM. These parameters may be benefi cial in predicting the risk of atherosclerosis in diabetic patients.
