Abstract Background. The burden of chronic kidney disease (CKD) in sub-Saharan Africa is unknown. The aim of this study was to investigate the prevalence and the risk factors associated with CKD in Kinshasa, the capital of the Democratic Republic of Congo (DRC). Methods. In a cross-sectional study, 503 adult residents in 10 of the 35 health zones of Kinshasa were studied in a randomly selected sample. Glomerular filtration rate was estimated using the simplified Modification of Diet in Renal Disease Study equation (eGFR) and compared with the Cockcroft–Gault equation for creatinine clearance. The associations between health characteristics, indicators of kidney damage (proteinuria) and kidney function (<60 ml/min/1.73 m2) were examined. Results. The prevalence of all stages of CKD according to K/DOQI guidelines was 12.4% [95% confidence interval (CI), 11.0–15.1%]. By stage, 2% had stage 1 (proteinuria with normal eGFR), 2.4% had stage 2 (proteinuria with an eGFR of 60–89 ml/min/1.73 m2), 7.8% had stage 3 (eGFR, 30–59 ml/min/1.73 m2) and 0.2% had stage 5 (eGFR < 15 ml/min/1.73 m2). Hypertension and age were independently associated with CKD stage 3. The prevalences of major non-communicable diseases considered in this study were 27.6% (95% CI, 25.7–31.3%) for hypertension, 11.7% (95% CI, 10.3–14.4%) for diabetes mellitus and 14.9% (95% CI, 13.3–17.9%) for obesity. Hypertension was also independently associated with proteinuria. Conclusion. More than 10% of the Kinshasa population exhibits signs of CKD, which is affecting adults in their productive years. Risk factors for CKD, including hypertension, diabetes and obesity, are increasing. These alarming data must guide current and future healthcare policies to meet the challenge raised by CKD in this city and hopefully in the whole country. [less ▲]

Abstract Background. Patients with chronic kidney disease stage 5 have a high prevalence of vascular calcification, but the specific anatomical distribution and severity of abdominal aortic calcification (AAC), in contrast to coronary calcification, is less well documented. AAC may be recorded using plain radiographs. The present report is an analysis of baseline data on AAC in patients enrolled in the CORD (Calcification Outcome in Renal Disease) study. Methods. A total of 47 centres in six European countries participated in this cross-sectional study. Inclusion criteria were age ≥18 years and duration of dialysis ≥3 months. Lateral lumbar radiography of the abdominal aortawas used to determine the overall AAC score, which is related to the severity of calcific deposits at lumbar vertebral segments L1–L4. The reliability of the method was tested by double reading of 64 radiographs (coefficient of correlation 0.9). Results. A lateral lumbar radiograph was obtained in 933 patients. Calcification (AAC score ≥ 1) was present in 81% of the patients; its severity increased significantly from L1 to L4 (P < 0.0001) and affected all of these segments in 51% of patients. Independent predictors for the presence and severity of calcification were age (odds ratio [OR] 1.103/year; P < 0.0001), duration of dialysis (OR 1.110/year; P = 0.002) and history of cardiovascular disease (OR 3.247; P < 0.0001). Conclusions. AAC detected by lateral lumbar radiograph is associated with several risk factors of uraemic calcification. This semi-quantitative method is more widely available and less expensive than the current procedures for studying calcification and could formpart of a pre-transplantworkup and cardiovascular risk stratification.

BACKGROUND: The European tacrolimus versus ciclosporin A microemulsion (CsA-ME) renal transplantation study showed that tacrolimus was significantly more effective in preventing acute rejection and had a superior cardiovascular risk profile at 6 months. METHODS: The endpoints of this investigator-initiated, observational, 36-month follow-up were acute rejection incidence rates, rates of patient and graft survival and renal function. An additional analysis was performed using the combined endpoints BPAR, graft loss and patient death. Data available from the original ITT population (557 patients; 286 tacrolimus and 271 CsA-ME) were analysed. RESULTS: A total of 231 tacrolimus and 217 CsA-ME patients participated. At 36 months, Kaplan-Meier-estimated BPAR-free survival rates were 78.8% in the tacrolimus group and 60.6% in the CsA-ME group, graft survival rates were 88.0% and 86.9% and patient survival rates were 96.6% and 96.7%, respectively. The estimated combined endpoint-free survival rate was 71.4% with tacrolimus and 55.4% with CsA-ME (P <or= 0.001, chi-square test). Significantly more CsA-ME patients crossed over to tacrolimus during the 3-year follow-up: 21.2% versus 2.6%, P <or= 0.0001, chi-square test. Most patients in the tacrolimus arm discontinued steroids and received monotherapy and fewer tacrolimus patients remained on a triple regimen. Mean serum creatinine concentration was 145.4 +/- 90.9 micromol/L with tacrolimus and 149.0 +/- 92.1 micromol/L with CsA-ME. Significantly more CsA-ME patients had a classified cholesterol value >6 mmol/L (26.3% versus 12.6%, P <or= 0.0003, chi-square test). CONCLUSIONS: Patients treated with tacrolimus had significantly higher combined endpoint-free survival rates and lower acute rejection rates with less immunosuppressive medication at 36 months.

In developing countries chronic kidney disease (CKD) is a growing problem. In most of sub-Saharan Africa, the vast majority of patients with CKD die because of lack of treatment. Renal replacement therapy is expensive, which makes it unaffordable to the residents of low-income regions. A solution to this problem may lie in preventive interventions. This editorial will focus on the reasons and some ways to reach such objectives. [less ▲]

Background. The percentage of hypochromic red blood cells (RBCs) (%HYPO) has been demonstrated as the best predictor of response to iron loading in haemodialysis patients treated with recombinant human erythropoietin (rHuEPO). However, we have previously shown that this parameter is positively influenced by erythropoietic activity since reticulocytes are considered hypochromic by cell counters. New cell counters are able to determine cell volume and haemoglobin (Hb) concentration separately on reticulocytes and mature erythrocytes. The aim of this study was to assess the sensitivity and specificity of mature erythrocyte parameters in detecting functional iron deficiency (FID). Methods. A total of 32 stable chronic haemodialysis patients in the maintenance phase of rHuEPO therapy were included. Classical parameters of iron monitoring and mature erythrocyte parameters were measured after a 4-week iron-free period. Patients were classified as responders (R) or non-responders (NR) to an iron load of 100 mg iron sucrose at each dialysis session for 4 weeks, according to whether their Hb increased by >1 g/dl at the end of iron loading. Results. Twelve patients were identified as responders. Receiver operating characteristic (ROC) curve analysis demonstrated %HYPO and its corresponding parameter on mature erythrocyte, %HYPOm, as the best predictors of FID. The other parameters were ordered as follows: tranferrin saturation (TSAT), ferritin (FRT), mature RBC Hb content (CHm), mean corpuscular Hb concentration (MCHC), percentage of mature erythrocytes with a low CHm (%lowCHm), mean content in Hb (MCH) and reticulocyte Hb content CHr. Comparing the parameters at different cut-offs, the best sensitivity, specificity and efficiency were demonstrated for HYPOm>6%. Conclusion. The best efficiency to predict FID was found for %HYPOm>6%. The predictive value of %HYPO was quite similar. The clinical impact of %HYPOm in iron monitoring should also be tested in the induction phase of rHuEPO treatment because of its independence from erythropoietic activity. [less ▲]

BACKGROUND: Comparison studies of calcineurin inhibitors as cornerstone immunosuppressants in renal transplantation have demonstrated that tacrolimus consistently reduces acute rejection rates and, in some studies, also improves long-term renal outcome in comparison to cyclosporin A (CsA). The aim of the present 2 year follow-up of the European Tacrolimus vs Cyclosporin A Microemulsion Renal Transplantation Study was to investigate long-term clinical outcome in terms of rate of acute rejection, graft and patient survival and graft function. METHODS: The European Tacrolimus vs Cyclosporin A Microemulsion Renal Transplantation Study was a randomized, comparative 6 month trial of the calcineurin inhibitors tacrolimus and CsA in combination with both azathioprine and steroids. The intent-to-treat population (ITT) consisted of 286 patients in the tacrolimus arm and 271 in the CsA microemulsion (CsA-ME) arm. Whereas whole blood level targets were 10-20 and 5-15 ng/ml for tacrolimus and 100-400 and 100-200 ng/ml for CsA during months 0-3 and 4-6, respectively, during the investigator-driven follow-up after termination of the main study (months 7-24) no specific calcineurin inhibitor target levels were required. Follow-up data were collected at 2 years post-transplantation from 237 (82.9% of the ITT population) patients who received tacrolimus and 222 (81.9% of the ITT population) patients who received CsA-ME. RESULTS: Calculated on ITT populations, mortality (2.0% vs 3.3%; P<0.05 in Kaplan-Meier analysis) was lower, but rate of graft loss (9.3% vs 11.2%; P = 0.12 in Kaplan-Meier analysis) was not significantly different after 2 years with tacrolimus- vs CsA-ME-based immunosuppression. Biopsy-proven acute rejection was significantly lower (19.6%) with tacrolimus than with CsA-ME (37.3%) during months 0-6 (P<0.0001), but was not significantly different during months 7-12 and 13-24 of follow-up (1.7% and 0.8% with tacrolimus and 4.7% and 0.9% with CsA-ME, respectively). A composite endpoint consisting of graft loss, patient death and biopsy-proven acute rejection occurred significantly more frequently in CsA-ME patients than in tacrolimus patients (42.8% vs 25.9%; P<0.001) during 24 months follow-up. Renal function 2 years post-transplant, measured by serum creatinine concentrations, was significantly better in tacrolimus-based compared with CsA-ME-based immunosuppression (136.9 vs 161.6 micromol/l; P<0.01). Cornerstone immunosuppression remained unchanged in 82.5% and 66.2% of patients treated with tacrolimus and CsA-ME, respectively. At 2 years, more patients in the tacrolimus arm were off steroids and received calcineurin inhibitor monotherapy, and fewer tacrolimus patients remained on a triple immunosuppressive regimen. The cardiovascular risk profile was affected favourably in the tacrolimus arm, with lower cholesterol and triglyceride concentrations (despite less use of cholesterol-lowering drugs); no significant difference in requirement for antidiabetic medication was noted. CONCLUSIONS: The 2 year study results confirm that tacrolimus is a highly efficacious cornerstone immunosuppressant in kidney transplantation. Tacrolimus-based immunosuppression may induce long-term benefits with regard to graft function and graft survival. The overall side-effect profile is considered to be favourable. [less ▲]
