Chronic kidney disease (CKD) is a clinical syndrome with a series of clinical manifestations and metabolic disorders caused by many diseases, which are characterized by progressive deterioration or irreversible damage of renal structures and functions. With the progress of epidemiological research, CKD has brought about huge economic and psychological burdens. There is a considerable risk of cardiovascular events or death than progression to end-stage renal disease for patients. Particular attentions should be paid to the new goals of reducing cardiovascular events and all-cause mortality. It is important to analyze the etiology and pathogenesis according to patients' ages, regions, primary disease as well as different stages of disease, and choose the appropriate therapeutic strategies accordingly. In clinical practice, due to the uncertainty of therapeutic effects of modern medicine based on the risk factors, it is necessary to use Chinese medicine (CM) to delay the disease progression and reduce comorbidities. Turbid toxin and blood stasis are two critical pathological factors worthy of concerns in the theory of CM. In addition, appropriate use of CM may help improve the quality of life of patients with CKD.

OBJECTIVETo investigate the association of fetuin-A with residual renal function and carotid artery calcification in patients with chronic kidney disease (CKD).

METHODSBlood examples were collected form 60 CKD patients in stages CKD3 to CKD5 (20 patients per stage) for measurement of serum fetuin-A, albumin, calcium, phosphorus and parathyroid hormone, cholesterol, triglycercide, low-density lipoprotein, and high-density lipoprotein. MDRD equation was used to calculate the estimated glomerular filtration rate (eGFR), and ELISA was used to detect serum fetuin-A. Color Doppler ultrasound was performed to measure carotid intima-media thickness (CIMT).

RESULTSAs the eGFR decreased, serum fetuin-A significantly decreased in CKD5 stage compared with that in CKD4 stage (P<0.05); compared with that in CKD3 stage, serum fetuin-A level was significantly lowered in CKD4 stage (P<0.05). Linear regression analysis suggested a significant positive correlation between fetuin-A and eGFR. The rate of carotid artery calcification was the highest in CKD5 stage. Rank correlation analysis showed a negative correlation between fetuin-A and cIMT, and logistic regression analysis identified decreased serum Fetuin-A as a risk factor of carotid artery calcification.

CONCLUSIONSerum fetuin-A decreases following the decrease in eGFR, and decreased serum Fetuin-A level is a risk factor of carotid artery calcification in CKD patients.

OBJECTIVETo investigate the effect of Shenmai Injection (SMI) on patients undergoing maintenance hemodialysis (MHD) suffered from malnutrition-inflammation complex syndrome (MICS).

METHODSForty patients undergoing MHD were randomly allocated into two groups, the SMI group and the control group, 20 in each group. They were treated for three months. Blood levels of albumin (Alb), high-sensitivity C-reactive protein (hs-CRP), interleukin 6 (IL-6) and interleukin 1beta (IL-1beta) as well as stomatologic parameters were measured before and after treatment. Meantime, the modified subjective global analysis of nutrition (SGAN) was used to assess patients' nutritional status, and the quantitative scoring system was adopted to get the malnutrition score (MS).

RESULTSIn the SMI group after treatment, levels of MS, hs-CRP, IL-6 and IL-1beta were lowered, levels of Alb, body weight, and SSF were increased significantly (P <0.05 or P <0.01); as compared with those in the control group, MS, hs-CRP and IL-6 were lower, while SSF and Alb were higher (P<0.05 or P< 0.01). Levels of IL-6 and IL-1beta, either in the SMI group or in the control group, were all higher than normal range (P<0.05). Correlation analysis showed significant correlation presented between MS value with levels of Alb (P<0.01) and IL-6 (P <0.05), also between IL-6 and Alb (P<0.05).

CONCLUSIONSMI can reduce the blood levels of hs-CRP, IL-6 and IL-1beta in patients undergoing MHD, improve their nutritional indices, suggesting that it could alleviate the MICS in these patients.

BACKGROUNDAtherosclerosis (AS) is an inflammatory disease. Inflammation was considered to play a role in the whole process of AS. This study aimed to analyze the relationships of inflammatory factors and risk factors with different target organ damages (TOD) in essential hypertension (EH) patients and to explore its clinical significance.

METHODSA total of 294 EH patients were selected and divided into four groups according to their conditions of TOD. Forty-eight healthy subjects were selected as control. The clinical biochemical parameters, serum amyloid A, serum tryptase, and lipoprotein-associated phospholipase A2 (Lp-PLA2) in each group were detected, and the related risk factors were also statistically analyzed.

RESULTSFibrinogen (Fbg) was the most significant independent risk factor in acute coronary syndrome (ACS) group (odds ratio [OR]: 22.242, 95% confidence interval [CI]: 6.458-76.609, P< 0.001) with the largest absolute value of the standardized partial regression coefficient B' (b': 1.079). Lp-PLA2 was the most significant independent risk factor in stroke group (OR: 13.699, 95% CI: 5.236-35.837, P< 0.001) with b' = 0.708. Uric acid (UA) was the most significant independent risk factor in renal damage group (OR: 15.307, 95% CI: 4.022-58.250, P< 0.001) with b' = 1.026.

CONCLUSIONSFbg, Lp-PLA2, and UA are the strongest independent risk factors toward the occurrence of ACS, ischemic stroke, and renal damage in EH patients, thus exhibiting the greatest impacts on the occurrence of ACS, ischemic stroke, and renal damage in EH patients, respectively.

Recent studies in Western countries have reported a significant association between glomerular filtration rate (GFR) and bone mineral density (BMD) in the absence of dialysis among the general population. However, there have been few studies regarding renal function and BMD among Korean or Asian subjects with moderate to severe (stage 3 or 4) chronic kidney disease (MS-CKD). The aim of the present study was to investigate the association between MS-CKD and BMD in the general Korean population. BMD, serum creatinine and other measures were obtained from 3,190 subjects (1,428 males and 1,762 females; the fourth Korean National Health and Nutrition Examination Survey). GFR was estimated using the Cockcroft-Gault formula, with adjustment for body surface area. After adjustment for all variables, multiple regression analysis showed that BMD in the femur neck, total femur and lumbar spine were positively associated with eGFR in both males and females. Additional analysis showed that MS-CKD was also significantly associated with osteoporosis in both males and females (odds ratio [OR] 2.20, 95% confidence interval [CI] 1.15-4.20 in males; and OR 1.96, 95% CI 1.33-2.88 in females). Individuals with MS-CKD may be at higher risk of osteoporosis even among Asians.

BACKGROUND/AIMS: Osteoprotegerin (OPG) and fetuin-A are vascular calcification regulators that may be related to high cardiovascular (CV) mortality in hemodialysis (HD) patients. We evaluated the relationship between OPG, fetuin-A, and pulse wave velocity (PWV), a marker of vascular stiffness, and determined whether OPG and fetuin-A were independent predictors of CV events in HD patients. METHODS: We conducted a prospective observational study in 97 HD patients. OPG and fetuin-A were measured at baseline and arterial stiffness was evaluated by PWV. All patients were stratified into tertiles according to serum OPG levels. RESULTS: A significant trend was observed across increasing serum OPG concentration tertiles for age, HD duration, systolic blood pressure, cholesterol, triglycerides, and PWV. Multiple linear regression analysis revealed that diabetes (beta = 0.430, p = 0.000) and OPG levels (beta = 0.308, p = 0.003) were independently associated with PWV. The frequency of new CV events was significantly higher in the upper OPG tertiles compared with those in the lower OPG tertiles. In Cox proportional hazards analysis, upper tertiles of OPG levels were significantly associated with CV events (hazard ratio = 4.536, p = 0.011). CONCLUSIONS: Serum OPG, but not fetuin-A, levels were closely associated with increased vascular stiffness, and higher OPG levels may be independent predictors of new CV events in HD patients.

Dyslipidemia is implicated in increased cardiovascular risk associated with chronic kidney disease (CKD) and in the progression of renal damage. This study compared 4 different lipid-related ratios (total cholesterol [TC]/high-density lipoprotein cholesterol [HDL-C], triglyceride [TG]/HDL-C, calculated low-density lipoprotein cholesterol [c-LDL-C]/HDL-C, and non-HDL-C/HDL-C ratio) for prediction of CKD stage 3 or more to investigate the association between them. This cross-sectional study included 8,650 adults who participated in the 2007-2008 Korean National Health and Nutrition Examination Survey. The overall prevalence of CKD stage 3 or more was 6.4%. For TG/HDL-C, the prevalence with CKD stage 3 or more increased with increasing quartile group in both sexes (P value for trend = 0.046 in men, 0.002 in women) while other lipid-related ratios showed increasing prevalence only in women. In comparison with the lowest quartile of the lipid-related ratios, only the fourth quartile of TG/HDL-C was associated with the prevalence of CKD stage 3 or more in both sexes after adjustment for multiple covariates (odds ratio [OR] for TG/HDL-C-Q4, 1.82; 95% CI [confidence interval], 1.09-3.03 in men, OR 2.45; 95% CI, 1.52-3.95 in women). In conclusion, TG/HDL-C is the only lipid-related ratio that is independently associated with CKD stage 3 or more in both sexes of Koreans.

There have been many studies between serum uric acid (UA) and chronic kidney disease (CKD). However, as far as we know, little research has been done to examine the prospective association between serum UA and development of CKD in Korean men. This prospective cohort study was performed using 18,778 men who participated in a health checkup program both on January, 2005 and on December, 2009. CKD was defined as an estimated glomerular filtration rate < 60 mL/min per 1.73 m2. The odds ratio (OR) from binary logistic regressions for the development of CKD was determined with respect to the quintiles grouping based on serum UA. During 74,821.4 person-years of follow-up, 110 men were found to develop CKD. The OR for the development of CKD increased as the quintiles for baseline serum UA levels increased from the first to fifth quintiles (1.00 vs 1.22, 1.19, 2.59, and 3.03, respectively, p for linear trend < 0.001) after adjusting for covariates. The adjusted OR comparing those participants with hyperuricemia ( > or = 7.0 mg/dL) to those with normouricemia ( < 7.0 mg/dL) was 1.96 (1.28-2.99). Elevated serum UA levels were independently associated with increased likelihood for the development of CKD in Korean men (IRB number: KBC10034).

BACKGROUND: We investigated whether the presence of diabetes mellitus (DM) was related to the degree of the anemia in predialytic patients with renal failure and what was the most relevant factor for anemia in patients with chronic kidney disease (CKD) from DM (DM-CKD). METHODS: Seventy seven patients (47 predialytic patients with long-term type 2 DM (DM-CKD) and 30 predialytic patients whose disease was due to other causes (non DM-CKD)) were enrolled in this study. The blood hemoglobin (Hb) and hematocrit, and the creatinine, ferritin, vitamin B12, folate, iron, LDH, albumin, hs-CRP, intact-PTH, erythropoietin, leptin and Insulin-like growth factor I (IGF-1) levels were measured using standard methods. The estimated GFR was calculated using the abbreviated MDRD equation. RESULTS: The two groups did not significantly differ as to age, gender, the serum creatinine level and the inflammatory status. The Hb level was significantly lower in the DM-CKD patients than that in the non DM-CKD patients (8.5+/-1.7 g/dL vs 9.6+/-1.6 g/dL, respectively, p=0.01). The Hb level was significantly lower in the DM-CKD patients who were being treated with ACE inhibitors (the DM-ACE patients) than that in the non DM-CKD patients who were being treated with ACE inhibitors (the non DM-ACE patients) (8.5+/-1.5 g/dL vs 10.8+/-1.6 g/dL, respectively, p=0.001). Multiple regression analysis indicated that serum IGF-1 concentration was independently associated with the Hb level (beta=0.425, p=0.02) in the DM-CKD patients. CONCLUSIONS: The Hb concentration was significantly lower in the DM-CKD patients than that in the non DM-CKD patients. It was independently associated with the serum IGF-1 concentration in the DM-CKD patients.
