Abstract
Post-transplant anemia is one of the most common complications in kidney transplant recipients, severely affecting patient prognosis and quality of life, and is an independent predictor of graft kidney loss and patient mortality. However, our clinical understanding and the attention given to post-transplant anemia are currently insufficient. This paper reviews the current status, risk factors, and therapeutic progress in anemia after transplantation in kidney transplant recipients. We recommend that clinical staff pay attention to anemia and its complications in kidney transplant recipients and intervene early for anemia.

Abstract
INTRODUCTION Kidney transplantation is a life-saving treatment for end-stage kidney disease (ESKD) patients. However, access to this treatment in Africa lags behind other regions, leading to significant disparities in care. We aimed to analyse the indications, demographics, and outcomes of kidney transplantation in Africa. METHOD We conducted a systematic review of studies from PubMed, Google Scholar, and African Journal Online using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We pooled and analysed data on procedure type, graft outcomes, donor type, prophylaxis, post-operative complications, and survival from 33 eligible studies. RESULT The most common causes of ESKD requiring transplantation were glomerulonephritis and nephroangiosclerosis. Open nephrectomy was the predominant surgical approach (95%). Living donors accounted for 56.3% (4221) of all donors, with 68.5% being related to the recipient. Cadaveric donors accounted for 43.7% (3280) of transplants. Graft rejection was the most common surgical complication (39.44%), and 60.49% of patients developed hypertension in the follow-up period. CONCLUSION Our study highlights the potential of kidney transplantation to improve the lives of ESKD patients in Africa. However, further research and infrastructure development are necessary to make this treatment more widespread and successful.

Kaohsiung J Med Sci 2018; 34:1-13. [PMID: 29310811 DOI: 10.1016/j.kjms.2017.07.007] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2017] [Revised: 05/10/2017] [Accepted: 07/27/2017] [Indexed: 11/25/2022] Open
Abstract
Renin-angiotensin system inhibitors, specifically angiotensin II converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB), have confirmed renoprotective benefits in patients with proteinuria and hypertension. However, it remains controversial whether these agents are beneficial to kidney recipients. We conducted this meta-analysis to evaluate the effects of ACEI/ARB treatment on patient and allograft survival after kidney transplant. The PubMed, Embase and Cochrane Library databases were searched for eligible articles from before May 2016, and we included 24 articles (9 randomised controlled trials [RCTs] and 15 cohort studies with 54,096 patients), in which patient or graft survival was compared between an ACEI/ARB treatment arm and a control arm. Pooled results showed that ACEI/ARB was associated with decreased risks of patient death (relative risk [RR] = 0.64; 95% confidence interval [CI]:0.49-0.84) and graft loss (RR = 0.59; 95%CI:0.47-0.74). Subgroup analysis of the cohorts revealed significantly reduced patient death (RR = 0.61; 95%CI:0.50-0.74) and graft loss (RR = 0.58; 95%CI:0.46-0.73), but this was not seen in RCTs (patient survival: RR = 0.84, 95%CI:0.39-1.81; graft survival: RR = 0.70, 95%CI:0.17-2.79). Significantly less graft loss was noted among patients with biopsy-proved chronic allograft nephropathy (CAN) (RR = 0.26, 95%CI:0.16-0.44). Furthermore, the benefit of ACEI/ARB on patient survival (RR = 0.62; 95%CI:0.47-0.83) and graft survival (RR = 0.58, 95%CI:0.47-0.71) was limited to those with ≥3years' follow-up. ACEI/ARB decreased proteinuria (P < 0.001) and lowered haemoglobin (P = 0.002), but the haemoglobin change requires no additional treatment (from 119-131 g/L to 107-123 g/L). We therefore concluded that ACEI/ARB treatment may reduce patient death and graft loss, but additional well-designed prospective studies are needed to validate these findings.

Reduction in new-onset diabetes mellitus after renal transplant with erythropoietin-stimulating agents: a retrospective cohort study. Can J Kidney Health Dis 2016; 3:23. [PMID: 27119016 PMCID: PMC4845385 DOI: 10.1186/s40697-016-0114-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2015] [Accepted: 04/05/2016] [Indexed: 11/24/2022] Open
Abstract
BACKGROUND Studies have shown that erythropoietin-stimulating agents (ESAs) protect mice against the development of diabetes through direct effects on pancreatic ß cells. However, the effect of ESAs on the incidence of diabetes in humans has not been well studied. It is unknown whether exposure to ESAs is associated with a reduced incidence of new-onset diabetes after transplant (NODAT). OBJECTIVE The objective of this study is to examine the relationship between ESA exposure post-renal transplant and the development of NODAT. DESIGN We performed a single center, retrospective cohort analysis. PATIENTS We compared patients who received a first live or deceased donor renal allograft, with any exposure to an ESA vs. those without such exposure and who developed NODAT and who did not. Patients with a prior history of diabetes mellitus or multi-organ transplant, including a second renal transplant were excluded. MEASUREMENTS AND METHODS NODAT was defined based on the 2008 Canadian Diabetes Association criteria. Multivariate logistic regression analysis was performed to determine factors independently associated with NODAT. RESULTS One hundred thirty-two (29 %) patients were exposed to an ESA, four of which developed NODAT compared to 128 who did not develop NODAT (p < 0.0001). Of those not exposed to an ESA, 15 % (48/319) developed NODAT. By Fisher's exact test, exposure to an ESA at any time post-transplant reduced the risk of developing NODAT; odds ratio (OR) = 0.08, 95 % confidence interval (CI) (0.018-0.352), p = 0.0008. Older age; OR = 1.41, 95 % CI (1.036-1.933), p < 0.02, higher random blood sugar at discharge; OR = 1.30, 95 % CI (1.077-1.57), p < 0.006 and deceased donor; OR 2.18 CI (1.009-4.729), p = 0.04 were associated with an increased risk of NODAT. LIMITATIONS The limitations of this study include its retrospective nature, single center, and homogenous population; thus, generalizability of the results must be approached with caution. CONCLUSION ESA exposure may be associated with a reduced incidence of NODAT in the post-renal transplant population. The role of ESA in preventing NODAT requires further investigation.

Abstract
BACKGROUND We evaluated the prevalence of pretransplantation and posttransplantation anemia and its effect on serum creatinine levels among living donor kidney transplant recipients. METHODS We reviewed retrospectively 170 adult patients who underwent living donor kidney transplantation between 1994 and 2009. We defined anemia as hemoglobin (Hb) ≤12 g/dL for women and ≤13 g/dL for men with severe anemia as Hb <11 g/dL for both men and women (World Health Organization criteria). Patients were also categorized according to Hb levels less than or greater than 10 g/dL for correlation with recipient serum creatinine levels at months 1, 3, 6, and 12. RESULTS Mean recipient and donor ages were 33 ± 10 and 45 ± 12 years, respectively. Mean cold ischemia time was 76 ± 43 minutes. At the time of transplantation, anemia and severe anemia prevalences were 86.7% and 58.8%, respectively. Anemia was observed in 64 patients (42.1%) at posttransplantation month 3. Pretransplantation severe anemia was a good predictor of both Hb levels and anemia presence posttransplantation. Pretransplantation anemia and severe anemia caused greater requirements for posttransplantation blood transfusions (P < .05). Younger age and female gender were significant risk factors for severe anemia pretransplantation. There was a significant correlation between posttransplantation Hb levels and serum creatinine levels at 12 month (P = .01). Recipient female gender and longer hospital stay were significant risk factors for both anemia and severe anemia posttransplantation. Higher recipient weight and history of acute rejection episode were also significant for posttransplantation severe anemia. CONCLUSION This study indicated that successful kidney transplantation had a positive effect on Hb levels. Posttransplantation anemia predicted worse graft function in the first month after transplantation.
