RESUMO
Rationale & Objective: Patients with chronic kidney disease (CKD) not receiving dialysis, including kidney transplant recipients, often experience difficulties regarding self-management. An important barrier for adherence to self-management recommendations may be the presence of psychological distress, consisting of depressive and anxiety symptoms. We investigated relationships between psychological distress and adherence to self-management recommendations. Study Design: Cross-sectional online questionnaire data as part of the E-GOAL study. Setting & Participants: Patients with CKD (estimated glomerular filtration rate, 20-89 mL/min/1.73 m2) were recruited from April 2018 to October 2020 at 4 hospitals in The Netherlands and completed online screening questionnaires. Exposures: Psychological distress, depressive symptoms, and anxiety symptoms. Outcomes: Dietary adherence, physical activity, medication adherence, smoking, body mass index, and a CKD self-management index (ie, the sum of 5 binary indicators of nonadherence to the recommended self-management factors). Analytical Approach: Adjusted multivariable regression and ordinal logistic regression analyses. Results: In our sample (N = 460), 27.2% of patients reported psychological distress, and 69.8% were nonadherent to 1 or more recommendations. Higher psychological distress was significantly associated with poorer dietary adherence (ßadj, -0.13; 95% CI, -0.23 to -0.04), less physical activity (ßadj, -0.13; 95% CI, -0.22 to -0.03), and lower medication adherence (ßadj, -0.15; 95% CI, -0.24 to -0.05), but not with smoking and body mass index. Findings were similar for depressive symptoms, whereas anxiety was only associated with poorer dietary and medication adherence. Every 1-point higher psychological distress was also associated with a higher likelihood of being nonadherent to an accumulating number of different recommendations (adjusted OR, 1.04; 95% CI, 1.02-1.07). Limitations: Cross-sectional design, possible residual confounding, and self-report. Conclusions: Many people with CKD experience psychological distress, of whom most have difficulties self-managing their CKD. Given the relationship between psychological distress and adherence to CKD self-management recommendations, behavioral interventions are needed to identify and treat psychological distress as a potential barrier to CKD self-management. Plain-Language Summary: This online questionnaire study investigated relationships between psychological distress and self-management among 460 people with chronic kidney disease. Over a quarter of them reported mild-to-severe psychological distress. Alarmingly, 4 out of 5 patients with psychological distress were also nonadherent to 1 or more self-management recommendations, and higher levels of psychological distress were associated with poorer dietary and medication adherence and lower physical activity. Moreover, patients who suffered from moderate-to-severe distress were relatively more often nonadherent to 3 or more recommendations compared with patients with no or mild distress symptoms. So, it seems that psychological distress can be a barrier for self-management. To support patients in managing chronic kidney disease, researchers and health professionals should not overlook patients' mental health.
RESUMO
Background: Socioeconomic status and ethnicity are not explicitly incorporated as risk factors in the four SCORE2 cardiovascular disease (CVD) risk models developed for country-wide implementation across Europe (low, moderate, high and very-high model). The aim of this study was to evaluate the performance of the four SCORE2 CVD risk prediction models in an ethnic and socioeconomic diverse population in the Netherlands. Methods: The SCORE2 CVD risk models were externally validated in socioeconomic and ethnic (by country of origin) subgroups, from a population-based cohort in the Netherlands, with GP, hospital and registry data. In total 155,000 individuals, between 40 and 70 years old in the study period from 2007 to 2020 and without previous CVD or diabetes were included. Variables (age, sex, smoking status, blood pressure, cholesterol) and outcome first CVD event (stroke, myocardial infarction, CVD death) were consistent with SCORE2. Findings: 6966 CVD events were observed, versus 5495 events predicted by the CVD low-risk model (intended for use in the Netherlands). Relative underprediction was similar in men and women (observed/predicted (OE-ratio), 1.3 and 1.2 in men and women, respectively). Underprediction was larger in low socioeconomic subgroups of the overall study population (OE-ratio 1.5 and 1.6 in men and women, respectively), and comparable in Dutch and the combined "other ethnicities" low socioeconomic subgroups. Underprediction in the Surinamese subgroup was largest (OE-ratio 1.9, in men and women), particularly in the low socioeconomic Surinamese subgroups (OE-ratio 2.5 and 2.1 in men and women). In the subgroups with underprediction in the low-risk model, the intermediate or high-risk SCORE2 models showed improved OE-ratios. Discrimination showed moderate performance in all subgroups and the four SCORE2 models, with C-statistics between 0.65 and 0.72, similar to the SCORE2 model development study. Interpretation: The SCORE 2 CVD risk model for low-risk countries (as the Netherlands are) was found to underpredict CVD risk, particularly in low socioeconomic and Surinamese ethnic subgroups. Including socioeconomic status and ethnicity as predictors in CVD risk models and implementing CVD risk adjustment within countries is desirable for adequate CVD risk prediction and counselling.

RESUMO
OBJECTIVE: Psychological distress is common among patients with chronic kidney disease and can interfere with disease self-management. We assessed the effectiveness of the personalized E-GOAL electronic health care pathway with screening and cognitive-behavioral therapy including self-management support, aimed to treat psychological distress and facilitate self-management among people with chronic kidney disease not on dialysis ( N = 121). METHODS: Primary outcome of the open two-arm parallel randomized controlled trial in four Dutch hospitals was psychological distress at posttest directly after the intervention and at 3-month follow-up. Secondary outcomes were physical and mental health-related quality of life, self-efficacy, chronic disease self-management, and personalized outcomes, that is, perceived progress compared with the previous time point on functioning (e.g., mood or social functioning) and self-management (e.g., dietary or medication adherence) outcomes that were prioritized by each individual. RESULTS: Linear mixed-effects analyses showed no significant time-by-group interaction effects for psychological distress, health-related quality of life, self-efficacy, and chronic condition self-management, whereas analyses of covariance showed significantly more perceived progress in the intervention group at posttest on personally prioritized areas of functioning ( b = 0.46, 95% confidence interval = 0.07-0.85) and self-management ( b = 0.55, 95% confidence interval = 0.16-0.95), with Cohen d values of 0.46 and 0.54 (medium effects), respectively. Effects on personalized outcomes were maintained at follow-up. CONCLUSIONS: Compared with regular care only, the electronic health intervention did not reduce psychological distress, whereas personalized outcomes did improve significantly after intervention. Future studies could consider personalized outcomes that reflect individually relevant areas and treatment goals, matching person-tailored treatments.

BACKGROUND: Socioeconomic status and ethnicity are not incorporated as predictors in country-level cardiovascular risk charts on mainland Europe. The aim of this study was to quantify the sex-specific cardiovascular death rates stratified by ethnicity and socioeconomic factors in an urban population in a universal healthcare system. METHODS: Age-standardized death rates (ASDR) were estimated in a dynamic population, aged 45-75 in the city of The Hague, the Netherlands, over the period 2007-2018, using data of Statistics Netherlands. Results were stratified by sex, ethnicity (country of birth) and socioeconomic status (prosperity) and compared with a European cut-off for high-risk countries (ASDR men 225/100,000 and women 175/100,000). FINDINGS: In total, 3073 CVD deaths occurred during 1·76 million person years follow-up. Estimated ASDRs (selected countries of birth) ranged from 126 (95%CI 89-174) in Moroccan men to 379 (95%CI 272-518) in Antillean men, and from 86 (95%CI 50-138) in Moroccan women to 170 (95%CI 142-202) in Surinamese women. ASDRs in the highest and lowest prosperity quintiles were 94 (95%CI 90-98) and 343 (95%CI 334-351) for men, and 43 (95%CI 41-46) and 140 (95%CI 135-145), for women, respectively. INTERPRETATION: In a diverse urban population, large health disparities in cardiovascular ASDRs exists across ethnic and socioeconomic subgroups. Identifying these high-risk subgroups followed by targeted preventive efforts, might provide a basis for improving cardiovascular health equity within communities. Instead of classifying countries as high-risk or low-risk, a shift towards focusing on these subgroups within countries might be needed.

RESUMO
Importance: Prevention of postcontrast acute kidney injury in patients with stage 3 chronic kidney disease (CKD) by means of prehydration has been standard care for years. However, evidence for the need for prehydration in this group is limited. Objective: To assess the renal safety of omitting prophylactic prehydration prior to iodine-based contrast media administration in patients with stage 3 CKD. Design, Setting, and Participants: The Kompas trial was a multicenter, noninferiority, randomized clinical trial conducted at 6 hospitals in the Netherlands in which 523 patients with stage 3 CKD were randomized in a 1:1 ratio to receive no prehydration or prehydration with 250 mL of 1.4% sodium bicarbonate administered in a 1-hour infusion before undergoing elective contrast-enhanced computed tomography from April 2013 through September 2016. Final follow-up was completed in September 2017. Data were analyzed from January 2018 to June 2019. Interventions: In total, 262 patients were allocated to the no prehydration group and 261 were allocated to receive prehydration. Analysis on the primary end point was available in 505 patients (96.6%). Main Outcomes and Measures: The primary end point was the mean relative increase in serum creatinine level 2 to 5 days after contrast administration compared with baseline (noninferiority margin of less than 10% increase in serum creatinine level). Secondary outcomes included the incidence of postcontrast acute kidney injury 2 to 5 days after contrast administration, mean relative increase in creatinine level 7 to 14 days after contrast administration, incidences of acute heart failure and renal failure requiring dialysis, and health care costs. Results: Of 554 patients randomized, 523 were included in the intention-to-treat analysis. The median (interquartile range) age was 74 (67-79) years; 336 (64.2%) were men and 187 (35.8%) were women. The mean (SD) relative increase in creatinine level 2 to 5 days after contrast administration compared with baseline was 3.0% (10.5) in the no prehydration group vs 3.5% (10.3) in the prehydration group (mean difference, 0.5; 95% CI, -1.3 to 2.3; P < .001 for noninferiority). Postcontrast acute kidney injury occurred in 11 patients (2.1%), including 7 of 262 (2.7%) in the no prehydration group and 4 of 261 (1.5%) in the prehydration group, which resulted in a relative risk of 1.7 (95% CI, 0.5-5.9; P = .36). None of the patients required dialysis or developed acute heart failure. Subgroup analyses showed no evidence of statistical interactions between treatment arms and predefined subgroups. Mean hydration costs were 119 (US $143.94) per patient in the prehydration group compared with 0 (US $0) in the no prehydration group (P < .001). Other health care costs were similar. Conclusions and Relevance: Among patients with stage 3 CKD undergoing contrast-enhanced computed tomography, withholding prehydration did not compromise patient safety. The findings of this study support the option of not giving prehydration as a safe and cost-efficient measure. Trial Registration: Netherlands Trial Register Identifier: NTR3764.

BACKGROUND: Guidelines advise periprocedural saline hydration for prevention of contrast induced-acute kidney injury (CI-AKI). We analysed whether 1-hour sodium bicarbonate hydration administered solely prior to intra-arterial contrast exposure is non-inferior to standard periprocedural saline hydration in chronic kidney disease (CKD) patients undergoing elective cardiovascular diagnostic or interventional contrast procedures. METHODS: We performed an open-label multicentre non-inferiority trial between 2011-2014. Patients were randomized to 1 hour pre-procedure sodium bicarbonate hydration (250 ml 1.4%, N = 168) or 4-12 hours saline hydration (1000 ml 0.9%, N = 165) prior to and following contrast administration (2000 ml of saline total). Primary outcome was the relative serum creatinine increase (%) 48-96 hours post contrast exposure. Secondary outcomes were: incidence of CI-AKI (serum creatinine increase>25% or >44µmol/L), recovery of renal function, the need for dialysis, and hospital costs within two months follow-up. RESULTS: Mean relative creatinine increase was 3.1% (95%CI 0.9 to 5.2%) in the bicarbonate and 1.1% (95%CI -1.2 to 3.5%) in the saline arm, mean difference 1.9% (95%CI -1.2 to 5.1%, p-non-inferiority <0.001). CI-AKI occurred in 11 (6.7%) patients randomized to sodium bicarbonate and 12 (7.5%) to saline (p = 0.79). Renal function did not fully recover in 40.0% and 44.4% of CI-AKI patients, respectively (p = 0.84). No patient required dialysis. Mean costs for preventive hydration and clinical preparation for the contrast procedure were $1158 for sodium bicarbonate vs. $1561 for saline (p < 0.001). CONCLUSION: Short hydration with sodium bicarbonate prior to elective cardiovascular diagnostic or therapeutic contrast procedures is non-inferior to standard periprocedural saline hydration in CKD patients with respect to renal safety and results in considerable healthcare savings.

There is a clear association between myelodysplastic syndrome (MDS)/chronic myelomonocytic leukemia (CMML) and autoimmune manifestations such as vasculitis. It is not clear if autoimmune manifestations in myelodysplastic syndrome are a cause or consequence. We describe two patients with polyarteritis nodosa and large vessel vasculitis, as presenting symptom of a myelodysplastic syndrome with excess blasts type 2 and chronic myelomonocytic leukemia respectively. Immunosuppressive treatment resulted in amelioration of the vasculitis with improvement of the myelodysplastic features in the first patient and rapid evolution to acute myeloid leukemia in the other patient. The association between MDS/CMML and autoimmune manifestations, such as vasculitis, emphasizes the role of autoimmunity in the clinical features and even pathogenesis of MDS/CMML.
RESUMO
OBJECTIVES: To analyze kidney injury molecule-1 (KIM-1) and neutrophil gelatinase-associated lipocalin (N-GAL) excretion post-intravenous contrast enhanced-CT (CE-CT) in patients with chronic kidney disease (CKD). METHODS: Patients were enrolled in a trial on hydration regimes to prevent contrast-induced acute kidney injury (CI-AKI). Blood and urine samples were taken at baseline, 4 - 6, and 48 - 96 h post CE-CT. Urinary KIM-1 and N-GAL values were normalized for urinary creatinine levels, presented as medians with 2.5 - 97.5 percentiles. RESULTS: Of the enrolled 511 patients, 10 (2%) were lost to follow-up. CI-AKI occurred in 3.9% of patients (20/501). Median KIM-1 values were 1.2 (0.1 - 7.7) at baseline, 1.3 (0.1 - 8.6) at 4 - 6 h, and 1.3 ng/mg (0.1 - 8.1) at 48 - 96 h post CE-CT (P = 0.39). Median N-GAL values were 41.0 (4.4 - 3,174.4), 48.9 (5.7 - 3,406.1), and 37.8 µg/mg (3.5 - 3,200.4), respectively (P = 0.07). The amount of KIM-1 and N-GAL excretion in follow-up was similar for patients with and without CI-AKI (P-value KIM-1 0.08, P-value N-GAL 0.73). Neither patient characteristics at baseline including severe CKD, medication use, nor contrast dose were associated with increased excretion of KIM-1 or N-GAL during follow-up. CONCLUSION: KIM-1 and N-GAL excretion were unaffected by CE-CT both in patients with and without CI-AKI, suggesting that CI-AKI was not accompanied by tubular injury. KEY POINTS: ⢠KIM-1 and N-GAL excretion were unaffected by intravenous contrast-enhanced CT (CE-CT). ⢠Patient or procedure characteristics were not associated with increased KIM-1 or N-GAL excretion. ⢠Performance of CE-CT in CKD patients is likely to be safe.

BACKGROUND: Guidelines recommend saline hydration for prophylaxis of contrast-induced acute kidney injury (CI-AKI) in patients with chronic kidney disease (CKD) undergoing intravenous contrast media-enhanced CT (CE-CT). The safety and efficacy of a brief hydration protocol using sodium bicarbonate in this population is unknown. We analysed whether 1-h sodium bicarbonate hydration prior to CE-CT is non-inferior to saline hydration prior to and after CE-CT in CKD patients. METHODS: We performed an open-label multicentre randomized trial. Patients were randomized to 250 mL of 1.4% sodium bicarbonate hydration prior to CE-CT or 1000 mL of 0.9% saline hydration prior to and, once again, after CE-CT. Primary outcome was the relative increase in serum creatinine 48-96 h post-CE-CT. Secondary outcomes were incidence of CI-AKI [serum creatinine increase >25%/>44 µmol/L (0.5 mg/dL)], recovery of renal function, the need for dialysis and 2-month hospital costs. RESULTS: Five hundred and seventy adult CKD patients undergoing CE-CT were randomized between 2010 and 2012, of whom 548 were included in the intention-to-treat population. Mean relative serum creatinine increase was 1.2% for sodium bicarbonate and 1.5% for saline (mean difference -0.3%; 95% confidence interval -2.7 to 2.1, P-value for non-inferiority <0.0001). CI-AKI occurred in 22 patients (4.1%); 8 (3.0%) randomized to sodium bicarbonate versus 14 (5.1%) to saline (P = 0.23). Renal function recovered in 75 and 69% of CI-AKI patients, respectively (P = 0.81). No patients developed a need for dialysis. Mean hydration costs per patient were 224 for the sodium bicarbonate and 683 for the saline regime (P < 0.001). Other healthcare costs were similar. CONCLUSIONS: Short hydration with sodium bicarbonate prior to CE-CT was non-inferior to peri-procedural saline hydration with respect to renal safety and may result in healthcare savings.

Treatment goals for patients with CKD are often unrealized for many reasons, but support by nurse practitioners may improve risk factor levels in these patients. Here, we analyzed renal endpoints of the Multifactorial Approach and Superior Treatment Efficacy in Renal Patients with the Aid of Nurse Practitioners (MASTERPLAN) study after extended follow-up to determine whether strict implementation of current CKD guidelines through the aid of nurse practitioners improves renal outcome. In total, 788 patients with moderate to severe CKD were randomized to receive nurse practitioner support added to physician care (intervention group) or physician care alone (control group). Median follow-up was 5.7 years. Renal outcome was a secondary endpoint of the MASTERPLAN study. We used a composite renal endpoint of death, ESRD, and 50% increase in serum creatinine. Event rates were compared with adjustment for baseline serum creatinine concentration and changes in estimated GFR were determined. During the randomized phase, there were small but significant differences between the groups in BP, proteinuria, LDL cholesterol, and use of aspirin, statins, active vitamin D, and antihypertensive medications, in favor of the intervention group. The intervention reduced the incidence of the composite renal endpoint by 20% (hazard ratio, 0.80; 95% confidence interval, 0.66 to 0.98; P=0.03). In the intervention group, the decrease in estimated GFR was 0.45 ml/min per 1.73 m(2) per year less than in the control group (P=0.01). In conclusion, additional support by nurse practitioners attenuated the decline of kidney function and improved renal outcome in patients with CKD.

BACKGROUND: Loin pain haematuria syndrome is characterised by episodes of loin pain and microscopic or macroscopic haematuria, without a urological origin. CASE DESCRIPTION: We describe a 39-year-old woman who was referred to us because of microscopic haematuria and proteinuria without an apparent cause, which had been present for 20 years. For 9 months she had also had continuous loin pain, aggravated by exertion. Additional examination showed erythrocytes in the renal tubules and a thin glomerular basement membrane. We made the diagnosis of "loin pain haematuria syndrome based on thin basement membrane nephropathy". CONCLUSION: Loin pain haematuria syndrome is a potentially debilitating disorder that is often poorly recognized due to the unfamiliarity of physicians with this condition. Treatment of patients with loin pain haematuria syndrome consists of patient education, treatment with ACE inhibitors, pain medication and cognitive behavioural therapy. Renal artery denervation can be considered in cases of persistent, disabling pain.

BACKGROUND/AIMS: Proteinuria is a risk marker for progression of chronic kidney disease (CKD) and treatment with an angiotensin-converting enzyme inhibitor/angiotensin II receptor blocker (ACEi/ARB) is beneficial in these patients. However, little is known about proteinuria and ACEi/ARB treatment in patients on specialized predialysis care. Therefore, we investigated the association of urinary protein excretion (UPE) and ACEi/ARB treatment with renal function decline (RFD) and/or the start of renal replacement therapy (RRT) in patients on predialysis care. METHODS: In the PREPARE-1 cohort, 547 incident predialysis patients (CKD stages IV-V), referred as part of the usual care to outpatient clinics of eight Dutch hospitals, were included (1999-2001) and followed until the start of RRT, mortality, or January 1, 2008. The main outcomes were rate of RFD, estimated as the slope of available eGFR measurements, and the start of RRT. RESULTS: Patients with mild proteinuria (>0.3 to ≤1.0 g/24 h) had an adjusted additional RFD of 0.35 ml/min/1.73 m(2)/month (95% CI: 0.01; 0.68) and a higher rate of starting RRT [adjusted HR: 1.70 (1.05; 2.77)] compared with patients without proteinuria (≤0.3 g/24 h). With every consecutive UPE category (>1.0 to ≤3.0, >3.0 to ≤6.0, and >6.0 g/24 h), RFD accelerated and the start of RRT was earlier. Furthermore, patients starting (n = 16) or continuing (n = 133) treatment with ACEi/ARBs during predialysis care had a lower rate of starting RRT compared with patients not using treatment [n = 152, adjusted HR: 0.56 (0.29; 1.08) and 0.90 (0.68; 1.20), respectively]. CONCLUSION: In patients on predialysis care, we confirmed that proteinuria is a risk marker for the progression of CKD. Furthermore, no evidence was present that the use of ACEi/ARBs is deleterious.

BACKGROUND: In the growing elderly predialysis population, little is known about the effect of identified risk factors on the progression to end-stage renal disease. Therefore, we investigated the association of systolic (SBP) and diastolic blood pressure (DBP) with the start of renal replacement therapy (RRT), in elderly (≥65 years) compared with young (<65 years) predialysis patients. METHODS: In the PREPARE-1 cohort, 547 incident predialysis patients, referred as part of the usual care to eight Dutch predialysis care outpatient clinics, were included (1999-2001) and followed until the start of dialysis, transplantation, death, or until 1 January 2008. The outcome was the start of RRT. All analyses were stratified for age; <65 years (young) and ≥65 years (elderly). RESULTS: In young predialysis patients (n = 268) higher SBP (every 20 mm Hg increase) and high DBP (DBP ≥100 mm Hg compared with 80-89 mm Hg) were associated with a higher rate of starting RRT (adjusted hazard ratio (HR) (95% confidence interval) 1.21 (1.09;1.34) and 1.74 (1.16;2.62), respectively). However, in elderly predialysis patients (n = 240) only patients with SBP ≥180 mm Hg had an increased rate compared with patients with 140-159 mm Hg (adjusted HR 2.33 (1.41;3.87)). Furthermore, patients with DBP <70 or ≥100 mm Hg had an increased rate of starting RRT, independent of SBP, compared with patients with 80-89 mm Hg (fully adjusted HR 1.72 (1.01;2.94) and 2.05 (1.13;3.73), respectively). CONCLUSIONS: The association of SBP and DBP with the start of RRT is different between elderly and young predialysis patients.

Strict implementation of guidelines directed at multiple targets reduces vascular risk in diabetic patients. Whether this also applies to patients with chronic kidney disease (CKD) is uncertain. To evaluate this, the MASTERPLAN Study randomized 788 patients with CKD (estimated GFR 20-70 ml/min) to receive additional intensive nurse practitioner support (the intervention group) or nephrologist care (the control group). The primary end point was a composite of myocardial infarction, stroke, or cardiovascular death. During a mean follow-up of 4.62 years, modest but significant decreases were found for blood pressure, LDL cholesterol, anemia, proteinuria along with the increased use of active vitamin D or analogs, aspirin and statins in the intervention group compared to the controls. No differences were found in the rate of smoking cessation, weight reduction, sodium excretion, physical activity, or glycemic control. Intensive control did not reduce the rate of the composite end point (21.3/1000 person-years in the intervention group compared to 23.8/1000 person-years in the controls (hazard ratio 0.90)). No differences were found in the secondary outcomes of vascular interventions, all-cause mortality or end-stage renal disease. Thus, the addition of intensive support by nurse practitioner care in patients with CKD improved some risk factor levels, but did not significantly reduce the rate of the primary or secondary end points.

PURPOSE: Contrast induced nephropathy (CIN) is defined as a decrease in renal function following administration of contrast media. The aim of this meta-analysis was to asses the overall risk of CIN, chronic loss of kidney function and the need for renal replacement therapy (RRT) after intravenous contrast enhanced CT-scan. Secondly, we aimed to identify subgroups at increased risk for CIN. MATERIALS AND METHODS: A literature search in Pubmed, Medline, Embase and Cochrane databases was performed. Data extraction was carried out independently by two reviewers. Meta-analysis and meta-regression were performed using an exact likelihood approach. RESULTS: Forty studies evaluating the incidence of CIN after CT were included. The pooled incidence of CIN was 6.4% (95% CI 5.0-8.1). The risk of RRT after CIN was low, 0.06% (95% CI 0.01-0.4). The decline in renal function persisted in 1.1% of patients (95% CI 0.6-2.1%). Patients with chronic kidney disease (odds ratio 2.26, p<0.001) or diabetes mellitus (odds ratio 3.10, p<0.001) were at increased risk for the development of CIN. CONCLUSION: CIN occurred in 6% of patients after contrast enhanced CT. In 1% of all patients undergoing contrast enhanced CT the decline in renal function persisted.

BACKGROUND: To investigate whether high blood pressure accelerates renal function decline in patients with advanced chronic kidney disease (CKD), we studied the association of systolic (SBP) and diastolic blood pressure (DBP) with decline in renal function and time until the start of renal replacement therapy (RRT) in patients with CKD stages IV-V on pre-dialysis care. METHODS: In the PREPARE-1 cohort 547 incident pre-dialysis patients, referred as part of the usual care to outpatient clinics of eight Dutch hospitals, were included between 1999 and 2001 and followed until the start of RRT, mortality, or end of follow-up (January 1st 2008). Main outcomes were rate of decline in renal function, estimated as the slope of available eGFR measurements, and time until the start of RRT. RESULTS: A total of 508 patients, 57% men and median (IQR) age of 63 (50-73) years, were available for analyses. Mean (SD) decline in renal function was 0.35 (0.75) ml/min/1.73 m2/month. Every 10 mmHg increase in SBP or DBP resulted in an accelerated decline in renal function (adjusted additional decline 0.04 (0.02;0.07) and 0.05 (0.00;0.11) ml/min/1.73 m2/month respectively) and an earlier start of RRT (adjusted HR 1.09 (1.04;1.14) and 1.16 (1.05;1.28) respectively). Furthermore, patients with SBP and DBP above the BP target goal of < 130/80 mmHg experienced a faster decline in renal function (adjusted additional decline 0.31 (0.08;0.53) ml/min/1.73 m2/month) and an earlier start of RRT (adjusted HR 2.08 (1.25;3.44)), compared to patients who achieved the target goal (11%). Comparing the decline in renal function and risk of starting RRT between patients with only SBP above the target (≥ 130 mmHg) and patients with both SBP and DBP below the target (< 130/80 mmHg), showed that the results were almost similar as compared to patients with both SBP and DBP above the target (adjusted additional decline 0.31 (0.04;0.58) ml/min/1.73 m2/month and adjusted HR 2.24 (1.26;3.97)). Therefore, it seems that especially having SBP above the target is harmful. CONCLUSIONS: In pre-dialysis patients with CKD stages IV-V, having blood pressure (especially SBP) above the target goal for CKD patients (< 130/80 mmHg) was associated with a faster decline in renal function and a later start of RRT.

BACKGROUND: Guidelines have set goals for risk factor management in chronic kidney disease (CKD) patients. These goals are often not met. In this analysis, we set out to assess the quality of risk factor management in CKD and to identify factors that determine the quality of care (QoC). For that purpose, baseline data of the MASTERPLAN (Multifactorial Approach and Superior Treatment Efficacy in Renal Patients with the Aid of Nurse practitioners) study have been used. MASTERPLAN is a multicentre study which evaluates the effect of a multifactorial intervention in prevalent CKD patients on cardiovascular (CV) events and progression of kidney failure. METHODS: QoC was quantified using a score based on the number of 11 defined treatment goals on target. The maximum score per patient was 11. RESULTS: The average (±SD) QoC score was 6.7 (±1.5). The average score per centre ranged from 5.9 to 6.9. In a multivariable analysis, centre proved to be a significant, independent determinant of QoC with a difference up to 0.7 between centres. This difference remained when adjustments were made for those risk factors primarily treated by pharmacotherapy. Other factors that were significantly related to the QoC were estimated glomerular filtration rate, Caucasian race, diabetes mellitus, diabetic nephropathy as cause of kidney disease and previous kidney transplantation. CONCLUSIONS: In CKD patients, risk factors for progression of kidney failure and CV events were inadequately controlled. Treatment centre proved to be an important determinant of QoC. This data may point towards the physician's interest and preference as important determinants of QoC. This is a potentially modifiable determinant of the quality of patient care [Trial registration ISRCTN registry: 73187232 (http://isrctn.org)].

Management of severe chronic kidney disease (CKD) involves dealing with medical, nursing and psychosocial problems and therefore warrants support from a multidisciplinary team. In the Kidney Disease Outcomes Quality Initiative (KDOQI) classification system of CKD, preparation for renal replacement therapy has been recommended in CKD stage 4, characterized by a reduction in the estimated glomerular filtration rate (GFR) of <30 ml/min. In this article we share our approach to perfecting predialysis care. Tools are given to make an estimation of the progression of kidney disease. Also the prevention and treatment of metabolic complications and cardiovascular risk management are summarized. Finally, the possibilities for dialysis but even more important, aiming for pre-emptive transplantation, are being discussed. Using a multidisciplinary integrated care approach predialysis care has come of age.
