Background: Metabolic acidosis (MA) is common in kidney transplant recipients (KTRs). Several studies have shown that MA is involved in the progression of chronic kidney disease. However, it is unclear if there is also a relationship between serum bicarbonate and graft function after kidney transplantation (KTx). We hypothesized that low serum bicarbonate is associated with a lower estimated glomerular filtration rate (eGFR) 1 year after KTx. Methods: We performed a post hoc analysis of a single-center, open-label randomized trial in 90 KTRs and investigated the relationship of serum bicarbonate and graft function in the first year after KTx. Results: Prevalence of MA was high after KTx (63%) and decreased to 28% after 1 year. Bicarbonate (20.6 ± 3.0 to 22.7 ± 2.7 mmol/L) increased in the first year after transplantation whereas eGFR (53.4 ± 15.8 to 56.9 ± 18.5 mL/min/1.73 m2) did not change significantly. Higher serum bicarbonate (p = 0.029) was associated with higher eGFR in the first year after KTx. Conclusion: Prevalence of MA is high in KTRs. In the first year after KTx, serum bicarbonate was positively correlated with eGFR, suggesting a potential role of MA in kidney graft function.

Abstract Objectives Maternal and fetal complications can occur in pregnant kidney transplant recipients. Since these are high-risk pregnancies, they require a multidisciplinary follow-up to prematurely detect adverse events. Identifying factors that would affect fetal, maternal and graft outcomes is essential to further stratify the risk of pregnant kidney transplant recipients. Methods All pregnancies in kidney transplant recipients followed in a single center for 30 years were included. Data included previous transplant information and blood and urine tests performed before pregnancy. Impact of graft function on fetal, maternal and graft outcomes was evaluated. Results There were 41 pregnancies among 34 patients. Mean gestational age of 35 ± 3 weeks. Caesarean section was performed in 69.4% of patients. Five pregnancies were unsuccessful (12.2%). Four patients suffered an acute graft dysfunction (9.8%) and 12 (29.3%) had a serious maternal hypertensive disorder (preeclampsia, eclampsia or HELLP syndrome). Graft function before pregnancy showed significant correlation with adverse outcomes. Conclusions A proteinuria >669 mg/g, serum creatinine >1.75 mg/dL and glomerular filtration rate <36.2 mL/min/1.73 m2 before pregnancy were correlated to graft dysfunction during pregnancy. Similar values of proteinuria were also associated with a risk of maternal hypertensive disorders and pregnancy failure. Therefore, in patients with proteinuria and graft dysfunction, follow-up should be stricter to quickly detect complications.

Delayed kidney graft function and acute rejection in the early post-transplant period affect both short and long-term allograft survival. Allograft rejection, as an inflammatory state, results in increased eryth-ropoietin resistance, which leads to decreased haemoglobin (Hb) level. We conducted this study to evaluate whether inflammation in the early post-transplant period could predict later anemia.This is a retrospective cohort study based on the analysis of 64 existing clinical records. Predictor. White blood cells (WBC) count obtained by the end of the first week post-transplant (W1). Covariates. Donor’s age, recipient’s age and sex. Outcome. Anemia identified at 12 months (M12) post engraftment.Median WBC count at W1 was 9,5 x103^L (5th - 95th percentile 5,2 x103^L -17,8 x 103/μΚ). Mean Hb values at M12 were 129,9 ± 20,3 g/L, in males 136,2 ± 20,1 g/L and in females 119,4 ± 16,2 g/L. The significant correlation was found between WBC at W1 and Hb at M12. Pearson coefficient of correlation r was -0,26, and 95% confidence interval (CI) for r was -0,47 to -0,015 (p=0,03). Univariate logistic regression showed significant association between WBC at W1 and Hb at M12 (OR 1,20; 95% CI 1,04 to 1,39, p=0,01). After the adjustment for donor’s and recipient’s age by transplantation and recipient’s sex, multiple regression showed that WBC count remained predictive of anemia at M12 (OR 1,17; 95% CI 1,01 to 1,36, p=0,03).Early post-transplant inflammatory response predicts later anemia in kidney transplant recipients. An increase in WBC count in the first week post-transplant by 109/L increases the risk for anemia after twelve months by 17%.

Introduction. CD3+CD4- CD8- cells represent one of the subpopulations of T-regulatory lymphocytes. According to literature reports, an increase in the content of graft-infiltrating CD3+CD4- CD8- T cells was detected in the heart xenograft tissues of an experimental model with a long-term graft survival. The efficacy of CD3+CD4- CD8- infusion to induce skin graft tolerance was described. Some studies have shown that a decrease in CD3+CD4- CD8- content in peripheral blood of patients undergoing to hematopoietic stem cell transplantation was associated with the development of a graft-versus-host reaction.Objectives. To study changes in the values of CD3+CD4- CD8- double-negative T lymphocytes in peripheral blood in kidney transplant recipients.Material and methods. The study included 165 recipients who underwent kidney transplantation. The creatinine and urea concentrations in blood were determined before surgery, on day 7, and day 360 after transplantation. The content of CD3+CD4- CD8- lymphocytes was studied before surgery, on the 3rd, 7th, 30th, 90th, 180th and 360th days after surgery. Early graft function was assessed on day 7 after transplantation. The function was defined as a primary one at creatinine levels below 300 μmol/L. The graft dysfunction was defined as creatinine values equal to or greater than 300 μmol/L and the need for dialysis in the first week after surgery. The satisfactory graft function after a year was characterized by the blood creatinine level below 150 μmol/L, absent episodes of graft rejection, and no need for dialysis in the first year of follow-up. There were 4 groups of recipients formed. The first group included patients with the primary graft function and satisfactory late graft function. The second group included patients with the primary function and late graft dysfunction. The third group included patients with the primary dysfunction and late satisfactory function. The fourth group included patients with the primary and late graft dysfunction.Results. In the first and second groups, there were no significant differences in the blood level of CD3+CD4- CD8- during the year. After a year, a significant CD3+CD4- CD8- decrease was noted in the group with late graft dysfunction. A similar tendency was revealed in the third and fourth groups. In the fourth group (with late graft dysfunction), the level of CD3+CD4- CD8- was significantly lower only after a year of observation compared with the levels in the third group. A negative correlation was noted between the CD3+CD4- CD8- values and the creatinine and urea levels. Thus, high CD3+CD4- CD8- values in kidney transplant recipients after a year were associated with a satisfactory graft function.Conclusions. 1. A stable 1-year satisfactory kidney graft function is characterized by an increase in the blood level of CD3+CD4- CD8- T lymphocytes. 2. A kidney graft dysfunction in the late post-transplant period is characterized by a decrease in the blood level of CD3+CD4- CD8- T lymphocytes.Authors declare no conflict of interest.

Cluster of differentiation 93 (CD93), also known as complement component 1q receptor 1 is a transmembrane glycoprotein expressed in endothelial and hematopoietic cells and associated with phagocytosis, cell adhesion, angiogenesis and inflammation. The extracellular part, soluble CD93 (sCD93), is released to body fluids in inflammation. Data on sCD93 in kidney diseases are limited. Our aim was to evaluate serum sCD93 in long-term kidney transplant recipients as a marker of inflammation and endothelial dysfunction that may be potentially useful in early recognition of graft dysfunction. Seventy-eight adult patients with functioning kidney graft and stable clinical state were examined at least one year after kidney transplantation. Serum sCD93 was measured by enzyme immunosorbent assay. Estimated glomerular filtration rate (eGFR) and albuminuria or proteinuria were assessed at baseline and over one-year follow-up. Increased sCD93 was associated with lower baseline eGFR independently of the confounders. Moreover, sCD93 was negatively associated with eGFR during one-year follow-up in simple analysis; however, this was not confirmed after adjustment for confounders. Baseline sCD93 was positively associated with baseline albuminuria and with increased proteinuria during the follow-up. Serum sCD93 was not correlated with other studied inflammatory markers (interleukin 6, C-reactive protein, procalcitonin and C3 and C4 complement components). To the best of our knowledge, this is the first report regarding the concentrations of sCD93 in kidney transplant recipients and one of the first reports showing the inverse association between sCD93 and renal function. Serum sCD93 should be further evaluated as a diagnostic and prognostic marker in renal transplantation.

ABSTRACT Introduction: The development of novel non-invasive biomarkers of kidney graft dysfunction, especially in the course of the delayed graft function period would be an important step forward in the clinical practice of kidney transplantation. Methods: We evaluated by RT-PCR the expression of miRNA-146 to -5p ribonucleic micro-acids (miRNAs) in the peripheral blood and renal tissue obtained from kidney transplant recipients who underwent a surveillance graft biopsy during the period of delayed graft function. Results: In biopsy samples, the expression of miR-146a-5p was significantly increased in the group of patients with delayed graft function (DGF) (n = 33) versus stables patients (STA) (n = 13) and patients with acute rejection (AR) (n = 9) (p = 0.008). In peripheral blood samples, a non-significant increase of miR-146a-5p expression was found in the DGF group versus STA and AR groups (p = 0.083). No significant correlation was found between levels of expression in biopsy and plasma. ROC curve analysis revealed an AUC of 0.75 (95% CI: 0.62-0.88) for the renal tissue expression and 0.67 (95% CI 0.52-0.81) for the peripheral blood expression. Conclusion: We conclude that miR-146a-5p expression has a distinct pattern in the renal tissue and perhaps in the peripheral blood in the setting of DGF. Further refinements and strategies for studies should be developed in the field of non-invasive molecular diagnosis of kidney graft dysfunction.
