Article: Survey of depression by beck depression inventory in uremic patients undergoing hemodialysis and hemodiafiltration.
[show abstract] [hide abstract]
ABSTRACT: High prevalence of depression has been reported in patients with end stage kidney disease and depression is associated with increased morbidity and mortality. We aimed to investigate the prevalence of depression in patients receiving standard hemodialysis (SHD) and hemodiafiltration (HDF) and compare the associated factors between these treatment modalities. The Beck Depression Inventory (BDI) was used to survey for major depressive symptoms. Demographic and biochemical data were reviewed and collected. Point prevalence of depression in HDF patients was significantly lower than SHD patients (23.9% vs. 43.1%, P < 0.05). The BDI score was also higher in SHD than HDF group (13.2 ± 11.6 vs. 8.7 ± 11.2, P < 0.05). SHD patients with major depressive symptoms had significantly lower levels of hemoglobin, albumin, creatinine, sodium and hand grip strength but had higher prevalence of diabetes and high sensitivity C-reactive protein (hs-CRP) levels. In HDF patients, phosphorus level was significantly lower in patients with major depressive symptoms. Logistic regression analysis revealed that hs-CRP, serum sodium and hand grip strength were significantly associated with major depressive symptoms in patients treated with SHD; while serum phosphorus was identified in HDF groups. We concluded that prevalence of depression was high in dialysis patients. Patients receiving HDF had a lower mean BDI score and a nearly 50% lower prevalence rate of major depressive symptoms than that of SHD. Factors associated with depression were different between two modalities.Therapeutic apheresis and dialysis: official peer-reviewed journal of the International Society for Apheresis, the Japanese Society for Apheresis, the Japanese Society for Dialysis Therapy 12/2012; 16(6):573-9. · 1.39 Impact Factor -
Article: Albuminuria, proteinuria, and urinary albumin to protein ratio in chronic kidney disease.
[show abstract] [hide abstract]
ABSTRACT: Both albuminuria and proteinuria are important disease markers of chronic kidney disease (CKD). Their relationship and the ratio between urinary albumin and protein in patients with CKD have not been investigated. Whether clinical features can affect these measurements is not clear. We conducted a cross-sectional study in 602 CKD patients. Demographic data, including age, gender, and co-morbidity such as diabetes, hypertension, hyperuricemia, and hyperlipidemia, were reviewed and recorded. Their urinary albumin, total protein, and creatinine were determined and urinary albumin to creatinine ratio (UACR), total protein to creatinine ratio (UPCR), and albumin to total protein ratio (UAPR) were calculated. Their estimated glomerular filtration rate (eGFR) was calculated according to serum creatinine. The correlation between UACR and UPCR was thus analyzed. We also investigated factors associated with these urinary measurements. UACR and UPCR increased progressively as renal function deteriorated, while UAPR increased to a plateau in CKD stage 4. There was direct relationship between UACR and UPCR. UAPR rose exponentially with the increase of both UACR and UPCR when UACR <500 mg/g or UPCR <1,000 mg/g. Multivariate regression analysis revealed diabetes and hyperuricemia were associated with increased UACR and UPCR, while both urinary parameters were inversely related to male gender and eGFR. Diabetes and hyperuricemia were associated with increased UAPR and UAPR was negatively correlated with age and eGFR. There was a significant association between UACR and UPCR in patients with CKD. Characteristics of patients, renal function, and co-morbidities all affected UACR, UPCR, and UAPR.Journal of Clinical Laboratory Analysis 02/2012; 26(2):82-92. · 1.38 Impact Factor -
Article: Lack of modulatory effect of simvastatin on indoxyl sulfate-induced activation of cultured endothelial cells.
[show abstract] [hide abstract]
ABSTRACT: Endothelial dysfunction is a common manifestation of chronic kidney disease (CKD). The protein-bound uremic toxins have emerged as important factors associated with cardiovascular disease and the outcome of CKD. The effect of indoxyl sulfate (IS) on endothelial cells remains unclear. Human umbilical endothelial cells (HUVEC) were incubated using IS at two concentrations: 100 μM and 1000 μM over two periods of time: 16 and 48 h. HUVEC were also pre-treated with simvastatin to examine its effect. RT-PCR was used to assess changes in the gene expression of intracellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), Monocyte chemotactic protein-1 (MCP-1), E-selectin, and angiotensin receptor type 1 (AT1R). Protein abundance of the investigated molecules was assessed by immunoblotting. Treatment with 100 μM IS for 16 h induced a 2-fold increase in the expression of ICAM-1, VCAM-1, and MCP-1. At a concentration of 1000 μM, there was a 2-3-fold increase. An extended treatment period at low concentrations was associated with a 2-3 fold increase and the increase of ICAM-1 and VCAM-1 was more prominent under high concentration. Results of immunoblotting confirmed an increase in the abundance of ICAM-1, VCAM-1 and MCP-1. No significant change was noted in E-selectin and AT1R according to concentration or treatment duration. Pre-treatment with simvastatin did not alter IS-induced changes. IS increased the expression of adhesion molecules of endothelial cells exhibiting a concentration and duration dependent pattern. Simvastatin did not demonstrate any effect on IS-associated endothelial activation.Life sciences 10/2011; 90(1-2):47-53. · 2.56 Impact Factor
