[PMID: 35510155 PMCID: PMC9059986 DOI: 10.2147/idr.s356543] [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: 01/10/2022] [Accepted: 04/15/2022] [Indexed: 12/02/2022] Open
Abstract
Background Infection remains a leading cause of morbidity and mortality in kidney transplant patients. This study aimed to investigate the risk factors of bacterial infection during the perioperative period of transplantation and the effects of infection on long-term clinical outcomes. Methods In total, 295 kidney transplantation recipients were included in this retrospective study and assigned to two groups: non-infected and infected. The tacrolimus concentration, pharmacogenomics, laboratory parameters, and clinical outcomes of both groups were evaluated. Results A relatively low incidence of urinary tract infection was observed in our cohort, and lung was identified as the most frequent site of infection. Gram-negative bacteria, such as Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, were the most common infecting strains in kidney transplant recipients. Patients with diabetes showed greater susceptibility to infection. Compared with the non-infected group, tacrolimus concentration was significantly lower on day 7 and 14 in the infected group. White blood cell count, neutrophil count, and C-reactive protein (CRP) in the infected group were markedly higher post-transplantation, while albumin levels were lower relative to the non-infected group. ABCB1 (rs2032582) genotype showed clear associations with infection. Furthermore, the incidence of delayed graft function (DGF) and early acute rejection (AR) before infection was significantly greater in the infected group. Finally, early post-transplant infection was associated with a marked increase in the incidence of AR, post-transplant diabetes mellitus (PTDM), and secondary infection. Conclusion Pre-diabetes, longer duration of catheterization, lower albumin, higher CRP, tacrolimus concentration on the day 7 and 14, early AR before infection, and DGF were closely related to postoperative infection in kidney transplantation recipients. Moreover, bacterial infection during the perioperative period was closely associated with AR, PTDM and secondary infection.

The Impact of Timing of Stent Removal on the Incidence of UTI, Recurrence, Symptomatology, Resistance, and Hospitalization in Renal Transplant Recipients. J Transplant 2021; 2021:3428260. [PMID: 34306740 PMCID: PMC8272658 DOI: 10.1155/2021/3428260] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2021] [Revised: 05/28/2021] [Accepted: 06/12/2021] [Indexed: 11/24/2022] Open
Abstract
Purpose To evaluate the impact of early (<3 weeks) versus late (>3 weeks) urinary stent removal on urinary tract infections (UTIs) post renal transplantation. Methods A retrospective study was performed including all adult renal transplants who were transplanted between January 2017 and May 2020 with a minimum of 6-month follow-up at King Abdulaziz Medical City, Riyadh, Saudi Arabia. Results A total of 279 kidney recipients included in the study were stratified into 114 in the early stent removal group (ESR) and 165 in the late stent removal group (LSR). Mean age was 43.4 ± 15.8; women: n: 114, 40.90%; and deceased donor transplant: n: 55, 19.70%. Mean stent removal time was 35.3 ± 28.0 days posttransplant (14.1 ± 4.6 days in the ESR versus 49.9 ± 28.1 days in LSR, p < 0.001). Seventy-four UTIs were diagnosed while the stents were in vivo or up to two weeks after the stent removal “UTIs related to the stent” (n = 20, 17.5% in ESR versus n = 54, 32.7% in LSR; p=0.006). By six months after transplantation, there were 97 UTIs (n = 36, 31.6% UTIs in ESR versus n = 61, 37% in LSR; p=0.373). Compared with UTIs diagnosed after stent removal, UTIs diagnosed while the stent was still in vivo tended to be complicated (17.9% versus 4.9%, p: 0.019), recurrent (66.1% versus 46.3%; p: 0.063), associated with bacteremia (10.7% versus 0%; p: 0.019), and requiring hospitalization (61% versus 24%, p: 0.024). Early stent removal decreased the need for expedited stent removal due to UTI reasons (rate of UTIs before stent removal) (n = 11, 9% in the early group versus n = 45, 27% in the late group; p=0.001). The effect on the rate of multidrug-resistant organisms (MDRO) was less clear (33% versus 47%, p: 0.205). Early stent removal was associated with a statistically significant reduction in the incidence of UTIs related to the stent (HR = 0.505, 95% CI: 0.302-0.844, p=0.009) without increasing the incidence of urological complications. Removing the stent before 21 days posttransplantation decreased UTIs related to stent (aOR: 0.403, CI: 0.218-0.744). Removing the stent before 14 days may even further decrease the risk of UTIs (aOR: 0.311, CI: 0.035- 2.726). Conclusion Early ureteric stent removal defined as less than 21 days post renal transplantation reduced the incidence of UTIs related to stent without increasing the incidence of urological complications. UTIs occurring while the ureteric stent still in vivo were notably associated with bacteremia and hospitalization. A randomized trial will be required to further determine the best timing for stent removal.

Magnetic Double-J-Stent Removal Without General Anaesthesia in Children. Urology 2021; 156:251-255. [PMID: 33493511 DOI: 10.1016/j.urology.2021.01.028] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2020] [Revised: 01/11/2021] [Accepted: 01/17/2021] [Indexed: 11/20/2022]
Abstract
OBJECTIVES To show the feasibility of magnetic double-J-stent (mDJS) removal without general anaesthesia in infants and children. METHODS A retrospective analysis of mDJS removals was conducted between February 2018 and July 2020 in a cohort of 32 consecutive paediatric patients. Only patients with unilateral ureteric stenting were included. Stent retrieval was performed in an outpatient setting. In males the junction of the retrieval-catheter and the mDJS was confirmed by transabdominal ultrasound. All patients were followed-up for 4-12 weeks after stent removal. RESULTS Thirty-two patients (54% males) were included. Median age was 3.8 years (range 1 month - 15 years). Ureteral stents remained in place for a median of 67.5 days (range 2 days - 6 months). General anaesthesia was necessary in one single patient due to expressed patient's and caregiver's wish. Thirty-one patients had stent removal without need for general anaesthesia. Thereof, nitrous oxide was used in 12 patients (37.5%), fentanyl in 3 patients (9.4%), midazolam in 3 patients (9.4%), and 17 patients (53.1%) did not need sedation at all. Seven patients (21.9%) being 8 months or younger had received peroral saccharosis. No complications occurred during stent removal. Retrieval was successful at first catheterization in 30 patients (93.8%). Two male patients needed a second catheterization (6.3%). CONCLUSION The use of magnetic DJS is safe in the paediatric population and spares general anaesthesia during removal in almost all patients.

Toll-like 4 receptor (TLR4) expression on peripheral blood mononuclear cells in renal transplant recipients with pre-transplant chronic interstitial nephritis indicates patients at risk of graft deterioration. Transpl Immunol 2020; 62:101319. [PMID: 32693120 DOI: 10.1016/j.trim.2020.101319] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/14/2019] [Revised: 07/08/2020] [Accepted: 07/12/2020] [Indexed: 10/23/2022]
Abstract
Data binding the expression of Toll-like 4 receptor (TLR4ex), transplanted kidney function, and the cause of pre-transplant end-stage renal disease are scarcely available. OBJECTIVE To investigate the relationship between pre-transplant chronic interstitial nephritis (CIN), TLR4ex and transplanted kidney function. MATERIALS AND METHODS TLR4ex was measured in peripheral blood mononuclear cells of 43 CIN kidney transplant recipients. We compared TLR4ex among 33 patients with pre-transplant chronic non-infectious interstitial nephritis (NIN) and 10 patients with pre-transplant chronic pyelonephritis (Py). At the beginning (Day-0) TLR4ex, as well as concentrations of cyclosporin A (CyA) and tacrolimus (TAC) were determined. Both CIN and NIN patients were divided according to the respective median of TLR4ex into groups of low-TLR4 expression (L-TLR4ex) and high-TLR4 expression (H-TLR4ex). Serum creatinine/glomerular filtration rate (sCr/EGFR) was assessed on Day-0 and after the follow-up (F-up). The magnitudes of sCr/EGFR change (ΔsCr/ΔEGFR) were evaluated. The treatment was maintained stable along the F-up period (median 11.9 months). RESULTS Day-0: in CIN with L-TLR4ex TAC was lower but sCr/EGFR were not different from H-TLR4ex; in Py TLR4ex and TAC were lower than in NIN with no difference in sCR/eGFR. After F-up: in CIN with L-TLR4ex sCR/EGFR and ΔsCr/ΔEGFR were worse than in H-TLR4ex; in Py sCR/EGFR and ΔsCr/ΔEGFR were worse than in NIN. The regression analysis points out prospective impact of Py and TLR4ex on sCR/eGFR and ΔsCr/ΔeGFR. CONCLUSION In CIN, both TLR4ex and Tac appear to be a useful positive predictor of the effectiveness of immunosuppression. Chronic pyelonephritis indirectly promotes faster progression of chronic transplanted kidney disease.

Transplantation of a Kidney With Duplicated Ureter Harvested From a Donor With Vascular Anomaly in the Form of Double Inferior Vena Cava: A Case Report. Transplant Proc 2020; 52:2533-2535. [PMID: 32307140 DOI: 10.1016/j.transproceed.2020.02.089] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2019] [Revised: 01/28/2020] [Accepted: 02/09/2020] [Indexed: 11/19/2022]
Abstract
During the organ procurement procedure, a surgeon encounters anatomic anomalies not very often but also not uncommonly. These changes may put the success of the transplant into question. Despite the thorough diagnosis of the potential donor, these anomalies are often diagnosed during organ donation. In our paper we present a case of kidney transplantation with duplicated ureter. The organ was collected from a donor with duplicated inferior vena cava. After transplantation, the kidney functioned immediately. Taking into consideration the well-being of the recipient, organs with anatomic abnormalities should be carefully considered for transplantation. This is especially important when there is a constant shortage of organs for transplantation.
