BackgroundPost-transplantation diabetes mellitus (PTDM) is associated with a higher risk of mortality and graft loss. The reported incidence of PTDM after kidney transplantation (KT) varies from 10% to 74% and varies by country and ethnicity. There are few reports of nationwide cohort studies on PTDM incidence and related factors in Korea. The purpose of this study was to evaluate incidence of PTDM and related factors within 1 year after KT in Korea.MethodsThe KoreaN cohort study for Outcome in patients With Kidney Transplantation (KNOW-KT) enrolled 1080 recipients from July 2012 to August 2016. This study included 723 recipients, excluding 273 patients with pretransplant DM and 84 patients who were lost from follow-up within 1 year after KT.ResultsAmong 723 recipients, 85 (11.8%) recipients were diagnosed and treated with PTDM. Recipient age, HLA mismatches, hemoglobin A1c (HbA1c), waist-hip ratio (WHR), and use of prednisolone were significantly higher in PTDM group than the nondiabetic group. In the multivariable logistic regression analysis, independent risk factors for PTDM were older recipient age, higher WHR, and HbA1c before KT.ConclusionThe incidence of PTDM was 11.8% in a nationwide Korean cohort study. The factors related to the development of PTDM within 1 year after KT were older recipient age and higher WHR, and HbA1c levels before KT. In recipients with high WHR, it is important to control pretransplant abdominal obesity to prevent PTDM after KT. 相似文献

Background
Posttransplant anemia (PTA) influences kidney graft function and prognosis; however, there is no consensus regarding target hemoglobin (Hb) levels.Methods
We examined several cases of PTA to identify any correlation between Hb levels and graft function. We evaluated 84 kidney transplant recipients (50 men and 34 women; mean age, 46.7 years) who were treated at our department between February 2004 and March 2012 and were available for a 2-year post-transplant follow-up.Results
Hb levels and serum creatinine levels before transplantation and at 1, 3, 6, 12, and 24 months after transplantation were compared. We examined the correlation between the degree of anemia and renal function among the patients. Data were analyzed using Spearman's rank correlation coefficient and Friedman tests. The mean pretransplantation Hb level was 10.4 g/dL, whereas Hb levels at 6, 12, and 24 months after transplantation were significantly increased to 11.6, 12.2, and 12.4 g/dL, respectively, suggesting an improvement in anemia after the transplantation. Correlation analysis between anemia and kidney graft dysfunction revealed significant correlations at 1, 3, 12, and 24 months after transplantation. Subjects were stratified for correlation analysis according to Hb level at 24 months after transplantation: <10, 10–10.9, 11.0–11.9, 12.0–12.9, and ≥13.0 g/dL. A significant improvement in kidney graft function was noted in patients with an Hb level ≥11 g/dL at 2 years after transplantation. Anemia improved significantly by 3 months after transplantation.Conclusions
A significant correlation between PTA and kidney graft function was apparent, and the prognosis for kidney graft function was poor in patients with Hb levels ≤11 g/dL. 相似文献5.

Hepcidin is a hormone that regulates the intestinal absorption of iron and its release from the reticuloendothelium. The objective of this study was to determine the use of hepcidin for kidney disease patients with a diagnosis of iron deficiency pretransplantation by evaluating the soluble transferrin receptor (sRTfR-F) index as a marker for iron deficiency. This transverse study of 164 pretransplant patients determined hematometry and conventional markers related to iron metabolism, as well as soluble transferrin receptor (sTfR), its index (sTfR-F), and serum hepcidin concentrations. The following markers of inflammation (MIF) were also assessed C-reactive protein (hs-CRP), interleukin-6 (IL-6), soluble IL-2 receptor (sIL-2R), tumor necrosis factor-α (TNF-α), and soluble TNF-α receptor (s-TNF-αR). Among the studied patients, 11.4% showed an absolute iron deficiency with ferritin concentrations < 100 ng/mL, a mean hepcidin value of 120.7 ± 38.5 ng/mL, and a mean sTfR-F value of 1.03 ± 0.3; 18.2% of patients displayed a ferritin > 800 ng/mL with mean hepcidin and sTfR-F values of 147.5 ± 36.6 ng/mL and 0.54 ± 0.2, respectively. Iron deficiency was not observed in the other patients when considering the conventional markers: ferritin > 100 ng/mL and transferrin saturation (ST) > 20%. However, this study showed that determination of hepcidin concentrations together with M/F improved the identification of iron deficiency in pretransplant patients by 21.6%. 相似文献

Chronic renal impairment is often associated with complex bone disorders. Improvement of secondary hyperparathyroidism (HPT) is expected after kidney transplant (KT) if the glomerular filtration rate is normalized.Patients and MethodsThere were 888 KTs performed between 1996 and 2017 at our department. A total of 558 general patients have been operated on for HPT during the same period. The 2 populations had a common part: out of the 558, a total of 69 (12.4%) were in end-stage renal failure when operated on because of secondary HPT. That also means that 7.8% of all KTs were associated with HPT. Retrospective, single-center analysis was performed using the patients' medical records. The aim of our study was to analyze the results of parathyroidectomies after KT.ResultsParathyroid surgery was performed on 19 patients (2.14%) because of HPT after KT. The applied surgical technique was total parathyroidectomy with autotransplant in 6 cases, subtotal parathyroidectomy in 3 cases, and selective parathyroidectomy in 10 cases. In all cases, histology revealed benign disease. Complications were observed in 10 cases (52%); there were 6 cases of postoperative hypocalcaemia (31.58%), 1 case of transient laryngeal recurrent nerve paresis (5.26%), and 6 cases of recurrent HPT (31.58%).SummaryThe first step of HPT management is calcimimetic drug treatment. It is essential to prevent possible complications with regular laboratory monitoring. If the proper conservative therapy is refractory or severe in complications, surgery should be chosen. If the patient is already waiting for a KT, it is worth performing the parathyroid surgery before KT. Close collaboration with endocrinologists and nephrologists is needed to achieve successful therapy. 相似文献

Background One of the most common bariatric operations is the laparoscopic Roux-en-Y gastric bypass (LRYGBP) in which the gastric capacity
is restricted and the absorption by the small intestine is reduced. The objective of this study was to evaluate the incidence
of iron, folate, and vitamin B12 deficiency anemia in patients undergoing LRYGBP.
Patients and methods Clinical records of 30 patients who underwent LRYGBP between July 2003 and January 2005 and had a minimum follow up of 24 months
at our outpatient clinic were included. Multivitamin supplementation was prescribed to all patients. The complete blood cell
count, plasma iron, total iron-binding capacity, transferrin saturation, serum folate, and cobalamin levels before surgery,
6 months, 1, 2, and 3 years after the surgery were analyzed.
Results There were 25 women (83.4%) and five men (16.6%) with ages from 21 to 56 years. Before surgery, two patients (6.6%) presented
ferropenic anemia. Iron deficiency was seen in 40 and 54.5% 2 and 3 years after surgery, respectively. Cobalamin deficiency
was observed in 33.3% at 2 years and in 27.2% at 3 years. At 2-year follow-up, 46.6% of the patients had already developed
anemia and 63.6% at 3 years. Folate deficiency was not observed in any patient.
Conclusion Our routine scheme of vitamin supplementation is not sufficient to prevent iron and vitamin B12 deficiencies in most patients. 相似文献

Background
Patients with a failed kidney transplant represent a unique chronic kidney disease population that is increasing in number and is at high risk of morbidity and mortality. Among transplant-naïve patients, those treated with peritoneal dialysis (PD) show an early survival advantage compared with those treated with hemodialysis (HD). But any advantage of PD after allograft failure is unknown. The aim of this study was to investigate the clinical outcomes of patients with failed allografts according to the type of dialysis modality.Method
We reviewed medical records of patients who initiated dialysis after kidney transplant failure from November 1982 to May 2011. Demographics features, clinical data, and survival outcomes were compared between PD and HD patients who had experienced allograft failure.Results
The 182 patients with failed allografts showed the most common cause to be chronic rejection. The median duration of function before allograft failure was 74.0 months. After allograft failure, 145 (79.7%) patients returned to HD and 37 (20.3%) to PD. Twenty-three patients (12.6%) died over the median 69.1 months duration of follow-up. During the observation period, 16 HD (11%) and 7 PD (8.9%) patients died. The survival rates of PD patients at 1 year were 91.2% and 84.4%, respectively, at 1 and 3 years, and those of HD patients 94.8% and 88.9%. There was no significant difference in the survivals of the 2 groups.Conclusions
The study suggests that the outcome of patients starting PD after kidney transplant failure was similar to those starting HD. Therefore, PD can be regarded to be a good treatment option for patients returning to dialysis after kidney transplant failure. 相似文献14.

Anemia is prevalent in kidney transplant recipients and likely contributes to morbidity and mortality. The definition of anemia as established by the World Health Organization and subsequently adopted by the American Society of Transplantation is a hemoglobin concentration of 12 g/dL or less in women and 13 g/dL or less in men. Using this definition, the prevalence of anemia is nearly 30%. The National Survey of Post Transplant Anemia (PTA) in kidney transplant recipients in Argentina was conducted to evaluate the incidence of PTA at 1 year and its relationship to variables that influence transplantation outcome. At 1 year posttransplantation, mean (SD) hemoglobin concentration was 12.43 (1.77) g/dL (n = 379), hematocrit concentration was 38.26% (5.59%) (n = 379), serum creatinine concentration was 1.51 (0.72) mg/dL (n = 380), and creatinine clearance was 60.8 (22.47) mL/min (n = 334). The prevalence of PTA in Argentina at 1 year posttransplantation was 42.25%. At univariate analysis, female sex, immunosuppression regimen (mycophenolate mofetil plus mammalian target of rapamycin), and pediatric age group were associated with anemia. At multivariate analysis, only renal function and pediatric age group were associated with anemia. The mean hemoglobin level at year of transplant was 12.43 g/dL +/−1.77 and the prevalence of PTA in Argentina at year of transplant is 42.25%. Results of our survey show a correlation between Hb levels and graft function and pediatric recipient. 相似文献

ARES is a multicenter, prospective study of the prevalence, management, and repercussions on the quality of life of anemia in renal transplant patients with a reduced renal function (creatinine clearance according to Cockcroft-Gault: ≤60 and >15 mL/min). The frequency of factor deficiency and its relationship with anemia were analyzed at the baseline time of the study. Of the 500 patients included in the main study, valid data were available for iron metabolism in n = 419 μg/dL; folic acid, n = 205 ng/mL; and vitamin B12, n = 210 pg/mL. Anemia was defined as hemoglobin ≤13 g/dL (men) or ≤12 g/dL (women) and/or use of erythropoietin (EPO). Anemic patients (59.4%) had less sideremia (73.4 vs 81.2 μg/dL; P = .008), but no significant differences were observed for transferrin saturation index (25.9% vs 25.5%), ferritin (167 vs 171 ng/mL), iron insufficiency (26.5% vs 36.2%), pronounced ferropenia (20.4% vs 20.1%), folic acid (7.5 vs 6.6 ng/mL), or vitamin B12 (486 vs 530 pg/mL). Treatment with oral or intravenous iron was much more frequent in anemic patients (31.6% vs 9.9%; P < .001). The logistic regression analysis of factors associated with anemia revealed that renal function and the use of angiotensin-converting enzyme (ACE) inhibitors were significant but not the degree of iron deficiency. In conclusion, iron deficiency in renal transplant patients with chronic nephropathy is frequent and insufficiently treated. Although it may be an aggravating factor, it was not shown to be a determining factor for the presence or absence of anemia in the patients as a group. 相似文献

Background
Patients undergoing transplantation procedures are at a high risk of developing infections because of the need for immunosuppression. Infections presenting directly after renal transplantation greatly influence the overall success of the procedure. The aim of this study was to evaluate the influence of postoperative infection on the length of survival after renal transplant.Methods
In 2009 a multicenter prospective trial evaluating the factors that influence the occurrence of postoperative infective complications was published by the authors. That study reported that 25 out of 232 recipients of a renal transplant were diagnosed with an infection. The present study shows the effect of postoperative infection on the length of survival after renal transplantation during a 15-year observation period. Statistical methods involved monofactorial and multifactorial Kaplan-Meier analysis for the length of survival and the Cox proportional hazards model for mortality prediction. A P value of <.05 was considered to indicate statistical significance.Results
The analysis demonstrated that the lifespan of renal transplant recipients was decreased in those with postoperative infection, at both year 10 of the observation period (P = .013) and 15 years after transplantation (P = .012). Moreover, it was ascertained that an infection in the postoperative period was an independent risk factor increasing the mortality after renal transplantation: P = .026; hazard ratio 2.90 (95% confidence interval, 1.13–7.41).Conclusions
The occurrence of an infection in the postoperative period significantly decreases the lifespan of a renal transplantation recipient. 相似文献18.

Background
Patients on peritoneal dialysis treatment represent 15% of the global dialysis population. The major complication of peritoneal dialysis is catheter and peritoneal infection. Peritoneal dialysis patients who receive kidney transplants are at increased risk of infection because of immunosuppressive therapy.Aim
The purpose of this study is to show our ideal timing to remove peritoneal catheter after kidney transplant, which gives adequate security on renal function recovery and reduction of septic risk.Method of Study
We analyzed the outcomes of 65 patients on peritoneal dialysis who underwent kidney transplant between 2000 and 2016.Results
In 61 cases there was an immediate graft functional recovery. In 4 cases there was a delayed graft function (DGF), and we performed a hemodialysis with temporary placement of a venous catheter. In all patients we removed peritoneal dialysis catheter 30 to 45 days after transplant. There has been 1 case of catheter infection, which was treated with antibiotic therapy.Discussion
Our average time to remove the peritoneal dialysis catheter was shorter than times in previous studies, between the 30th and 45th postoperative day. In the 4 cases in which there has been a DGF, we performed hemodialysis treatment to avoid, in the immediate postoperative period, direct insults to the peritoneum by local dialysis procedures.Conclusion
Our experience show that the 30th to 45th postoperative day is a good time frame, better yet a good watershed between the safe removal of peritoneal catheter when patients have a stabilized renal function and the possibility of leaving it in situ, to resume peritoneal dialysis in case of persistent DGF. 相似文献20.

Hematopoietic stem cell transplant (HSCT) is used in advanced hematologic diseases to restart the immune system. Kidney damage remains significant complication of hematopoietic cell transplant (HCT) affecting the mortality of transplant recipients. The aim of the study was to assess the advancement of chronic kidney disease (CKD) in patients after HSCT. We studied 150 patients who underwent allo-HSCT treatment in our center in years 1995 to 2020 because of acute myeloid leukemia in 47% of patients, acute lymphoblastic leukemia in 19%, and lymphoma in 32%. The mean age of patients with acute leukemia is 48 years (including acute myeloid leukemia it is 47 years, and including acute lymphoblastic leukemia it is 32 years). The mean age of lymphoma patients is 34 years. We studied the prevalence and stages of CKD. CKD stage 3a and 3b was found in 24.6%. None of the patients studied had CKD stage 4 or 5. In patients after HSCT because of both acute myeloid leukemia and acute lymphoblastic leukemia, CKD stage 3a was found in 19% and stage 3b in 7.3%. Estimated glomerular filtration rate (eGFR) >90 mL/min/1.73 m2, was found in 36.8% of this population, whereas eGFR between 90 and 60 mL/min/1.73 m2 was observed in 36.8%. In patients with lymphoma who underwent HSCT, CKD stage 3a was found in 18%, while CKD stage 3b was diagnosed in 27% of the patients. An eGFR >90 mL/min/1.73 m2, was found in 27% of this population, whereas eGFR between 90 and 60 mL/min/1.73 m2 was observed in 27% of patients. The categorization of patients according to the underlying disease is important because other drugs are used in therapy of conditioning before HCT. CKD in patients after allogeneic HSCT is common, although advanced stages were not observed, probably because the age of the population studied was not advanced. CKD in these vulnerable patients may be because of prior chemotherapy, conditioning regimen, post-HSCT calcineurin therapy, and other possible nephrotoxic drugs. 相似文献
