Background: Neural precursor cell expressed developmentally down-regulated 4-like (NEDD4L) is a candidate gene for hypertension, and carriers of an intact NEDD4L C2-domain,encoded by the NEDD4L rs4149601 (G/A) GG genotype, together with the C-allele of the NEDD4L rs2288774 (C/T) polymorphism have been found be associated with hypertension both in African Americans and whites. However, there is no data on the relationship between polymorphism of NEDD4L rs4149601 and rs2288774 and hypertension in Chinese chronic kidney disease (CKD) patients. The purpose of the current study was to investigate the relationship between the variation of NEDD4L rs4149601, rs2288774 and hypertension in CKD patients. Methods: A total of 546 Chines Hans CKD patients were enrolled in our study. The SNPs were genotyped using PCR-based techniques. All patients underwent ambulatory blood pressure monitoring, and clinical data were also collected. Multivariate logistic regression analysis was used to identify the relationship between polymorphisms and hypertension. Results: 506 patients carried GG/GA genotype and 30 carried AA genotype. Rs4149601 AA genotype carriers had significantly higher rate of hypertension (68.3% vs 46.2%, P = 0.022) than GG/GA genotype carriers by Chi-squared test. AA genotype carriers also had a higher day-time and bedtime systolic blood pressure (142±16 vs 135±23, P=0.036; 137±18 vs 127±13, P=0.022, respectively) when compared with GG/GA genotype carriers. AA genotype [OR= 3.08, 95% CI (1.06-9.80)], lowever eGFR [OR=0.98, 95% CI (0.97-0.99)], older age [OR=1.03, 95% CI (1.01-1.05)] were independently associated with hypertension in CKD patients by multivariate logistic regression. However, No difference was found in blood pressure with rs2288774 TT/TC/CC genotypes, and no difference was found in the incidence of hypertension among patients with three genotypes. Conclusions: Our results suggested 4149601AA genotype of NEDD4L may be associated with hypertension in CKD patients, and further genetic and functional studies are required to understand its role in the manifestation of hypertension in Chinese CKD patients.

AbstractAmbulatory blood pressure monitoring (ABPM) can produce many variables, of which the lowest nocturnal systolic blood pressure (LNSBP) currently used in calculating morning surge is occasionally overlooked in recent kidney studies compared with other ABPM parameters. We explored the clinical effects of LNSBP in elderly patients with chronic kidney disease (CKD) in a multicenter, observational cohort study. A total of 356 elderly patients with CKD from 19 clinics were included in this analysis. We used multiple logistic regression and survival analyses to assess the associations between the lowest nocturnal systolic blood pressure and heavy proteinuria and kidney disease outcomes, respectively. The median age was 66 years, and 66.6% were men. The median eGFR was 49.2 ml/min/1.73 m2. Multivariate logistic regression analysis demonstrated that LNSBP (OR 1.24; 95% CI 1.10–1.39; P < 0.001; per 10 mmHg) was associated with heavy proteinuria. During the median follow-up of 23 months, 70 patients (19.7%) had a composite outcome; of these, 25 initiated dialysis, 25 had 40% eGFR loss, and 20 died. Cox analysis showed that the renal risk of LNSBP for CKD outcomes remained significant even after adjusting for background factors, including age, sex, medical history of hypertension and diabetes, smoking status, eGFR, 24-h proteinuria, and etiology of CKD (HR 1.18; 95% CI 1.06–1.32; P = 0.002; per 10 mmHg). Concentrating on LNSBP could be valuable in guiding antihypertensive treatment to control heavy proteinuria and improve renal prognosis in elderly CKD patients.

<b><i>Introduction:</i></b> Chronic kidney disease is common in patients with acute ischemic stroke. We investigated whether chronic kidney disease has an impact on anticoagulation treatment recommendations after ischemic stroke or transient ischemic attack (TIA) related with atrial fibrillation (AF). <b><i>Materials and Methods:</i></b> We extracted treatment-related data concerning stroke/TIA patients with AF and available estimated glomerular filtration rates (eGFR) from a monocentric prospective German stroke registry. Chronic kidney disease was defined as eGFR &#x3c;60 mL/min/1.73 m<sup>2</sup>. Using uni- and multivariate logistic regression analyses, we investigated whether chronic kidney disease was associated with a lower probability to be treated with anticoagulation early after stroke. <b><i>Results:</i></b> A total of 273 patients entered the analysis. In 242 AF patients (88.6%), oral anticoagulation was recommended after stroke. In multivariate logistic regression analysis, chronic kidney disease was not identified as an independent factor for the decision against anticoagulation (OR 1.63, 95% CI: 0.50–5.31, <i>p</i> = 0.421); only increasing age (OR 1.10, 95% CI: 1.00–1.21, <i>p</i> = 0.061) and a modified Rankin Scale &#x3e;3 at discharge (OR 3.41, 95% CI: 0.88–13.24, <i>p</i> = 0.077) showed a nonsignificant trend for the decision to omit anticoagulation. A total of 155 of 167 patients (92.8%) were still anticoagulated at follow-up. A total of 44 patients with chronic kidney disease completed follow-up, and of those, 37 were still anticoagulated (84%). In patients without chronic kidney disease, 118/167 (70.7%) had continued anticoagulation (<i>p</i> = 0.310). <b><i>Conclusion:</i></b> Our results show that chronic kidney disease was not the main factor in the decision to withhold oral anticoagulation in patients with recent stroke/TIA and AF.

Objective To examine the relation between the results of ambulatory 24-hour blood pressure monitoring (ABPM) and left ventricular mass index (LVMI), then to find the independent determinant for left ventricular hypertrophy (LVH) in peritoneal dialysis (PD) patients. Finally, to evaluate the differences in the clinical and cardiovascular characteristics between patients on continuous ambulatory PD (CAPD) and continuous cyclic PD (CCPD). Design An open, nonrandomized, cross-sectional study. Setting Divisions of nephrology and cardiology in a medical center. Patients Thirty-two uremic patients on maintenance PD therapy (22 patients on CAPD, and 10 on CCPD) without anatomical heart disease or history of receiving long-term hemodialysis. Interventions Home blood pressure (BP) and office BP were measured using the Korotkoff sound technique by sphygmomanometer. ABPM was employed for continuous measurement of BP. Echocardiography was performed for measurement of cardiac parameters and calculation of LVMI. Main Outcome Measures Multivariate logistic regression analysis was performed for independent determinant of LVH in PD patients. The differences in clinical and cardiovascular characteristics between CAPD and CCPD patients were compared. Results Simple regression analysis showed positive correlations between LVMI and the duration of hypertension, ambulatory nighttime BP/BP load/BP load > 30%, serum phosphate, calcium–phosphate product, ultrafiltration (UF) volume, and percentage of UF volume during the nighttime. A negative correlation was noted between LVMI and dipping. In multiple regression analysis, the duration of hypertension was the only variable linked to LVMI. In multivariate logistic regression analysis, only ambulatory nighttime systolic BP load > 30% had an independent association with LVH. There were correlations between office/home BP and ambulatory 24-hour BP. In addition, CCPD patients had higher LVMI, UF volume during the nighttime, and percentage of UF volume during the nighttime than those of CAPD patients. Conclusions In this study, ambulatory nighttime systolic BP load > 30% had an independent association with LVH. Office and home BP measurements were correlated with ABPM in PD patients. The result that CCPD patients had a higher LVMI than CAPD patients may be due to a relative volume overload during the daytime in CCPD patients.

Abstract Background: Low MBL2 concentration and MBL2 genotype variants have been associated with an increased risk of infection in various clinical settings. Pulmonary infection is a major complication of HSCT. We examined the relationship of MBL genotypes with post-engraftment bacterial (B-PNA) and fungal (F-PNA) pneumonia Methods: Retrospective review of 236 non-consecutive, non-selected patients who underwent HSCT at MSKCC from 1/1/2000–4/30/2007. Microbiologically confirmed infections and pneumonias were recorded. Antifungal prophylaxis consisted of fluconazole 400 mg daily. Patients at high risk for mold infection received mold-active prophylaxis. After 1/1/2006 voriconazole was the first line anti-mold prophylaxis. Genotype was determined by PR-Melting Curve Analysis on blood or buccal swab specimens. MBL genotype was classified as wild-type: A/A (MBL-sufficient, MBL-S) or variant-type: A/O, O/O (MBL deficient, MBL-D). Patients were followed for up to 2 years. Statistical analysis: Fisher’s Exact test was used to compare the incidence rate between MBL-S and MBL-D patients. Multivariate logistical regression models were used to investigate the relationship between bacterial or fungal pneumonia and MBL genotype, matched related donor (MRD), myeloablative conditioning (MC) peripheral blood as stem cell source (PBSC), acute GVHD grade 2–4 (aGVHD). The results from Maximum Likelihood Estimates were summarized. Results: Transplant characteristics: 80% MC, 76% PBSC, 48.6% MRD. Incidence of aGVHD: 22.4%. MBL genotypes: One-hundred and forty-two (60%) patients were homozygous for wild-type MBL2 (AA), 85(36%) were heterozygous (A/0) and 9 (3.8%) were homozygous for variant genotypes (OO). Transplant characteristics, rates of GVHD, relapse-free and overall survival were similar between MBL-D and MBL-S. There was higher incidence of overall bacterial infections in MBL-D compared to MBL-S pts (47.87% vs 36.62%, p=0.1049). MBL-D had a higher incidence of B-PNA (12.7% vs 4.9%, p=0.048). In multivariate logistic regression analysis, MBL-D(p=0.04) and aGVHD(p=0.06) were likely associated with B-PNA. Rates of overall fungal infections and F-PNA were similar [among MBL-D and MBL-S pts (12.77% vs 9.86%, p=0.5277) and (8.51% vs 7.75%, p=0.1049) respectively]. In multivariate logistic regression analysis only aGVHD was statistically significantly associated with F-PNA p=0.0002. Conclusions: 1) MBL-D genotype was likely associated with increased risk of bacterial pneumonia. 2) MBL-D and aGVHD were risk factors for B-PNA. 3) Further analyses are in progress to evaluate the effect of MBL-D on fungal pneumonia in patients who received mold prophylaxis versus patients who did not receive mold prophylaxis. 4) Prospective studies are needed to assess the relative contribution of MBL-D genotype on the risk of pulmonary infection in HSCT.

OBJECT Intracranial revascularization surgeries are an effective treatment for moyamoya disease and other intracranial vascular obliterative diseases. However, in some cases, wound-related complications develop after surgery. Although the incidence of wound complication is supposed to be higher than that with a usual craniotomy, this complication has rarely been the focus of studies in the literature that report the outcomes of revascularization surgeries. Here, the relationship between intracranial revascularization surgeries and their complications is statistically assessed. METHODS Between October 2004 and February 2010, 71 patients were treated using cerebral revascularization surgeries on 98 sides of the head. The relationship between wound complications and operative technique was retrospectively assessed. Multivariate logistic regression analysis was performed to identify the risk factors of wound complication, including operative technique, age, sex, diabetes mellitus (DM), hypertension, hyperlipidemia, and smoking history. RESULTS In total, there were 21 (21.4%) operative wound complications. Of these 21 complications, there were 14 (66.7%) minor complications and 7 (33.3%) major complications. No statistically significant relationship was found between wound complications and any surgical procedure. A trend toward severer complications was demonstrated for the procedures that used both STA branches (“double” procedures) in comparison with the procedures that used only 1 STA branch (“single” procedures, p = 0.016, Cochran-Armitage trend test). Multivariate logistic regression analysis also revealed that double procedures demonstrated a significantly higher incidence of wound complications than single procedures (OR 3.087, p = 0.048). DM was found to be a risk factor for wound complication (OR 9.42, p = 0.02), but age, sex, hypertension, and hyperlipidemia were not associated with the incidence of complications. Even though the blood supply to the scalp is abundant due to 5 arteriovenous systems, sometimes cutaneous necrosis develops after intracranial revascularization surgeries. The galeal blood supply is thought to be crucial for preventing wound-related complications. Special care is also thought to be required for DM patients. CONCLUSIONS Revascularization surgeries seemed to demonstrate a higher risk of wound-related complications. Double-type procedures, which use both branches of the STA, and a history of DM were found to be risk factors for wound-related complications. Attention should be paid to the design of the galeal incision and vessel harvest line. Also, special attention should be paid to patients with DM.

The Relationship

Background: Although various modalities of hemodialysis (HD) are presumed to have different effects on insulin resistance (IR), the relationship between hemodiafiltration (HDF) and IR has not been fully evaluated. Methods: In a cross-sectional study, 82 non-diabetic HD patients were enrolled. The patients were divided into two groups according to the median homeostasis model assessment index (HOMA-IR) value of 1.685. Clinical and biochemical data were compared, and multivariate logistic regression analysis was performed to identify the independent factors associated with higher HOMA-IR. Results: The higher HOMA-IR group had increased body mass index (BMI), decreased HDL cholesterol, and lower beta-2 microglobulin reduction rate (β2-MG RR) compared to the lower HOMA-IR group. HOMA-IR was significantly correlated with β2-MG RR. In addition, HDF patients had lower HOMA-IR levels compared with low flux hemodialysis patients. On multivariate logistic regression analysis, BMI and HDF treatment were independent factors associated with higher and lower HOMA-IR, respectively. Conclusion: This study suggests that HDF treatment may reduce IR in non-diabetic HD patients.
