RESUMEN
We investigated the risk factors for pulmonary hypertension (PH) in patients receiving maintenance peritoneal dialysis (MPD). A group of 180 end-stage renal disease patients (124 men and 56 women; mean age: 56.43±8.36) were enrolled in our study, which was conducted between January 2009 and June 2014. All of the patients received MPD treatment in the Dialysis Center of the Second Affiliated Hospital of Soochow University. Clinical data, laboratory indices, and echocardiographic data from these patients were collected, and follow-ups were scheduled bi-monthly. The incidence and relevant risk factors of PH were analyzed. The differences in measurement data were compared by t-test and enumeration data were compared with the χ2 test. Among the 180 patients receiving MPD, 60 were diagnosed with PH. The remaining 120 were regarded as the non-PH group. Significant differences were observed in the clinical data, laboratory indices, and echocardiographic data between the PH and non-PH patients (all P<0.05). Furthermore, hypertensive nephropathy patients on MPD showed a significantly higher incidence of PH compared with non-hypertensive nephropathy patients (P<0.05). Logistic regression analysis showed that the proportion of internal arteriovenous fistula, C-reactive protein levels, and ejection fraction were the highest risk factors for PH in patients receiving MPD. Our study shows that there is a high incidence of PH in patients receiving MPD and hypertensive nephropathy patients have an increased susceptibility to PH.

Several previous studies have demonstrated that elevated levels of fibroblast growth factor-23 (FGF-23) may be involved in atherosclerosis and contribute to the high mortality rate of peritoneal dialysis (PD) patients. The aim of this study was to determine the precise role of FGF-23 in the pathogenesis of atherosclerosis in PD patients. Between April 2009 and January 2012, 62 PD patients and 25 control subjects were included in the study. An enzyme-linked immunosorbent assay was conducted to test for plasma FGF-23 levels. Carotid artery intima-media thickness (CIMT), left ventricular mass index (LVMI), and myocardial performance index (MPI) were determined by ultrasonography. Plasma Ca(2+), P(3+), calcium-phosphorus product, parathyroid hormone, N-terminal pro-brain natriuretic peptide, and cardiac troponin I were also detected. Plasma FGF-23 levels in PD patients were significantly higher than those in control subjects. PD patients with CIMT > 1.0 mm showed the highest levels of FGF-23. Plasma P(3+), calcium-phosphorous product, plasma parathyroid hormone, CIMT, LVMI, and MPI levels were positively associated with plasma FGF-23 levels. Multiple-stepwise regression analyses revealed that plasma P(3+), plasma parathyroid hormone, CIMT, LVMI, and MPI levels were strongly associated with plasma FGF-23 levels. However, no correlations were observed in plasma N-terminal pro-brain natriuretic hormone and cardiac troponin I levels. Plasma FGF- 23 levels may play an important role in the initiation and progression of atherosclerosis. Thus, detecting and defining plasma FGF-23 levels may be a promising biomarker for the early detection of atherosclerosis in PD patients.
