Results: The mean daily salt excretion was 9.9 ± 2.6 g. BP and eGFR were not different among for groups. However, incidence of overt proteinuria was significantly higher in the first quartile (Q1: 23%, Q2: 9%, Q3: 2%, Q4: 2%, p < 0.001). Conclusion: Low daily salt excretion was correlated with proteinuria in non-diabetic patients. Although the cause and effect relationship between salt intake and proteinuria could not be determined in BAY 73-4506 this study, low daily

salt excretion could be a marker for proteinuria in non-diabetic outpatients.

The impact of the number of medications on the components of BP (systolic, SBP; diastolic, DBP) in Asian CKD patients is unclear. We assessed the effects of the number of anti-hypertensive agents on BP components

Ibrutinib in a multi-ethnic Asian population of stable CKD patients. Methods: We prospectively recruited 613 patients (male 55.1%, Chinese 74.7%, Indian 6.4%, Malay 11.4%, Others 7.5%; 35.7% diabetes) with mean age 57.8 ± 14.5 years. BP was measured according to guidelines using calibrated automatic manometers. Glomerular filtration rate (GFR) was estimated using the CKD-EPI equation. ANOVA was used to compare means of BP components with number of anti-hypertensive medications, and Tukey-Kramer HSD for pairwise comparisons. Linear regression was used to assess associations of BP with continuous variables. Non-normally distributed data was natural log-transformed for analyses. Results: The mean SBP was 139 ± 21 mmHg, DBP

74 ± 11 mmHg, serum creatinine 166 ± 115 μmol/L, and GFR 53 ± 32 mL/min/1.73 m2. SBP increased with lower GFR (p < 0.001), whereas DBP decreased with lower GFR (p = 0.0052). Mean SBP increased with increasing number of antihypertensive agents used (p < 0.001), whereas mean DBP decreased with ≥3 antihypertensive Bcl-w agents used (p = 0.0020, Table 1). Conclusions: Clinical practice guidelines recommend different component BP targets for CKD patients. Increasing number of antihypertensive agents use results in a divergence in the achievement of targets. Further research into improved methods of monitoring and treatment is required to better achieve targets.
