Abstract
BACKGROUND A kidney recipient's urinary tract infection (UTI) can result in infectious problems and be a risk factor for less successful transplant outcomes. UTI risk factors are still controversial. The present study aimed to investigate the prevalence of UTI and its association with risk factors in kidney recipients. METHOD Twenty-six papers published between 2005 and 2022 were retrieved using keywords and searching Medlib, ScienceDirect, PubMed, and other databases. If possible, the pooled prevalence of UTI in kidney recipients and odds ratio (OR) with a 95% confidence interval for each risk factor were calculated. The data were analyzed using the random effects model in R and Stata 14. RESULTS The total sample size was 72,600, with an average age of 48.7 years. The pooled prevalence of UTI was 35% (95% CI, 30-40%). The estimated risk factors for UTI were female (OR = 3.13; 95%CI: 2.35-4.17), older age (OR = 1.03; 95%CI: 1-1.05), history of UTI (OR = 1.31; 95%CI) CI: 1.05-1.63), receiving a kidney from a deceased donor (OR = 1.59; 95%CI: 1.23-2.35), long-term use of an indwelling catheter (OR = 3.03; 95%CI: 1.59-6.59), a ureteral stent (OR = 1.54; 95%CI: 1.16-2.06), diabetes (OR = 1.17; 95%CI: 0.97-1.41), hypertension (OR = 1.6; 95%CI: 1.26-2.28), acute rejection process (OR = 2.22; 95%CI: 1.45-3.4), and abnormal urinary tract anatomy (OR = 2.87; 95%CI 1.44-5.74). CONCLUSION This meta-analysis revealed that UTIs are a significant problem in kidney recipients. Factors such as female sex, old age, history of UTIs, deceased donor, long-term use of an indwelling catheter, diabetes, acute rejection process, use of ureteral stent, abnormal urinary tract anatomy, and hypertension were related to an increased risk of UTIs in kidney recipients.

Abstract
Background and Objectives: Asymptomatic bacteriuria (ASB) is prevalent in kidney transplant recipients (KTRs) and is hypothesized to heighten the risk of subsequent urinary tract infections (UTIs). Whether antibiotic treatment of ASB in KTRs is beneficial has not been elucidated. Materials and Methods: We carried out a systematic review and meta-analysis of all randomized controlled trials (RCTs) and quasi-RCTs that examined the merits of managing asymptomatic bacteriuria in KTRs. The primary outcomes were rates of symptomatic urinary tract infections (UTIs) and antimicrobial resistance. Results: Five studies encompassing 566 patients were included. No significant difference in symptomatic UTI rates was found between antibiotics and no treatment groups (relative risk (RR) 1.05, 95% confidence interval (CI) = 0.78-1.41), with moderate heterogeneity (I2 = 36%). Antibiotic treatment was found to present an uncertain risk for the development of drug-resistant strains (RR = 1.51, 95% CI = 0.95-2.40, I2 = 0%). In all trials, no significant difference between study arms was demonstrated regarding patient and graft outcomes, such as graft function, graft loss, hospitalization due to UTI, all-cause mortality, or acute rejection. Conclusions: The practice of screening and treating kidney transplant patients for asymptomatic bacteriuria does not curtail the incidence of future symptomatic UTIs, increase antimicrobial resistance, or affect graft outcomes. Whether early treatment of ASB after kidney transplantation (<2 months) is beneficial requires more RCTs.

Abstract
Introduction Lower respiratory tract infections (LRTIs) among renal transplant recipients (RTRs) are a significant cause of morbidity and mortality. This study aimed to analyse the aetiology, outcome, and risk factors associated with mortality. Methods We analysed baseline transplant characteristics, symptoms, hospital course, laboratory, serological and microbial results, and their association with the outcome of all RTRs between January 2011 and December 2019. Results A total of 206 LRTI patients out of 1051 RTRs were analysed. The incidence proportion was nearly 22 episodes per 1000 patients per year. The mean age was 39.3 years, with male predominance. Bacterial was the most common aetiology (53%), and staphylococcus was the most common species. Among the fungal causes (14%), 68% had aspergillus infection. More than one-third RTRs died during the hospital course mainly because of bacterial causes (42.6%). The aspergillus infection was the most common fungus associated with 50% mortality. On multi-variate analysis, sepsis, septic shock, and the need for mechanical ventilation independently predicted mortality. Conclusion Bacterial aetiology was the most common cause; though the fungal aetiology was seen less, it was associated with higher mortality. Mortality in RTR with LRTI was associated with sepsis, septic shock, and the need for mechanical ventilation.

Abstract
BACKGROUND Infectious complications in kidney transplant recipients (KTRs) are well studied in temperate countries but remain barely known in tropical ones. The main objective of this study was to describe infection-related hospitalizations in patients living in the Amazon, where it has never been described. METHODS All KTRs residing in French Guiana between 2007 and 2018 were included retrospectively. Infection-related hospitalizations were collected in the main medical centers of the territory. RESULTS Eighty-two patients were included, and 42 were infected during the study period (51%). Eighty-seven infections were identified. The main sites of infection were urinary, in 29% of cases (25/87), and pulmonary, in 22% of cases (19/87). When documented (48/87), bacterial infections were predominant (35/48), followed by viral (8/48), fungal (4/48), and parasitic infections (1/48). Endemic so-called tropical infections accounted for 6% of infections (5/87). Histoplasma capsulatum was the most commonly isolated fungus (2/4). CONCLUSIONS This study suggests that the spectrum of infections in KTRs in French Guiana differs little from that of temperate countries. Nevertheless, some tropical infections are described. More studies on fungal infections in KTRs should be undertaken to clarify the weight of histoplasmosis in these patients.

Abstract
UTI has been reported as the most prevalent infectious complication after-kidney transplantation. This study aimed to evaluate the bacterial urinary tract infection among renal transplant recipients, and causative microorganisms from the Middle East. We searched literatures reporting the prevalence of UTI, bacterial pathogens, and antibiotic resistance pattern from January 1, 2010-May 10, 2020 for patients with renal transplant recipients from the Middle East in international databases. Terms used were; "Urinary tract infection", "UTI", "bacterial pathogens", "bacterial infection", "renal transplant", "kidney transplant", post - renal transplant, "antibiotic resistance", "Middle East", Turkey, Iran, Jordan, Kuwait, Bahrain, Lebanon, United Arab Emirates, Qatar, Cyprus, Yemen, Iraq, Egypt, Palestine, and Syria. Data analyzed using CMA software. The prevalence of UTI among renal transplant recipients from the Middle East varied between 4.5 and 85%. The combined prevalence of UTI was reported by 37.9% (95% Cl: 28.3-48.5). The most prevalent organisms recovered from urine samples of patients with UTI were E. coli and Klebsiella with prevalence rate of 57.5%, and 15%, respectively. Also, Coagulase negative Staphylococcus (15%), and Enterococci (11.2%) were the most predominant among Gram positive microorganisms. The most resistance among Gram negative microorganisms belonged to Ceftazidime with frequency of 90% followed by Carbenicillin and Cephalexin with prevalence of 87.3%, and 84%, respectively. The effective antibiotic was Imipenem (15.2%). Regarding the high UTI rate in renal transplant recipients from the Middle East, and the significant presence of both Gram negative and Gram positive microorganisms as the most prevalent uropathogens after renal transplantation should be considered when selecting empirical antibacterial therapy.

Abstract
BACKGROUND Urinary tract infection is the most common bacterial infection after kidney transplant. Some studies suggested that urinary tract infection could impair graft survival, but this issue remains debated. The objective of this study was to analyze the association between acute pyelonephritis (APN) and the risk of kidney graft failure. METHODS We performed a retrospective cohort study including patients who received a kidney transplant from 2001 to 2009 at a university hospital in Rio de Janeiro, Brazil. They were followed until December 2015. The primary outcome was graft failure. Follow-up of patients who died with a functioning graft was censored on the date of death. Cox proportional hazards method was used in multivariable analysis to assess risk factors for graft failure. The occurrence of the first episode of APN and acute rejection were modeled as time-dependent variables. RESULTS A total of 587 patients were included. Of these, 112 recipients (19%) developed 173 episodes of APN. Graft failure occurred in 150 patients (25%) after a median follow-up of 79 months. The factors associated with graft failure in the multivariate analyses were age of the transplant recipient (hazard ratio [HR], 0.97 per year; 95% confidence interval [CI], 0.96-0.99; P < .01), occurrence of delayed graft function (HR, 2.42; 95% CI, 1.72-3.40; P < .01), and acute rejection (HR, 2.71; 95% CI, 1.92-3.82; P < .01). There was no association between APN and graft failure (HR, 1.05; 95% CI, 0.65-1.68; P = .85). CONCLUSIONS Our results suggest that the occurrence of APN is not associated with a significant reduction in graft survival after kidney transplant.

Abstract
BACKGROUND Routine treatment for asymptomatic bacteriuria (ASB) after renal transplantation (RT) represents nowadays a controversial topic, being unknown its impact on the overall prognosis of the transplanted patient. METHODS Studies published during 1970-2019 that evaluated the benefit of treating ASB after RT regarding the risk of renal complications were included. The primary outcome was to assess whether the treatment is associated with a lower risk of symptomatic urinary tract infection (UTI) or an improved renal function at the end of the follow-up period. The secondary outcome was the risk of acute graft rejection (AGR). A meta-analysis with a random-effect model was performed. Heterogeneity was assessed with the I2 measure. RESULTS Fifteen studies were included. The incidence of ASB in the first month and the first year after RT was 22% and 30%, respectively. ASB was not correlated to AGR (OR 1.18; 95% CI, 0.78-1.79). Eight studies compared the outcomes of ASB treatment, finding no benefit of treating regarding the risk of symptomatic UTI (OR 1.08; 95% CI, 0.63-1.84; I2 = 35%) or the change in renal function (mean difference in serum creatinine concentration-0.03 mg/dL,95% CI-0.15-0.10; I2 = 53%). CONCLUSIONS Asymptomatic bacteriuria represents a frequent finding after RT, highlighting the need for appropriate management of this condition. Considering that its treatment did not decrease the risk of the studied complications, antibiotic therapy should start to be questioned, as it has been related to higher rates of antimicrobial resistance and high economic costs.

Abstract
BACKGROUND During routine post-kidney transplant care, most European transplant physicians screen patients for asymptomatic bacteriuria. The usefulness of this strategy is debated. To make screening cost-effective, asymptomatic bacteriuria should be prevalent enough to justify the expense, and antibiotics should improve patient outcomes significantly if asymptomatic bacteriuria is detected. Regrettably, the prevalence of asymptomatic bacteriuria among kidney transplant recipients is not well defined. METHODS To determine the prevalence of asymptomatic bacteriuria among kidney transplant recipients, we did a cross-sectional study among kidney transplant recipients undergoing routine surveillance in three outpatient transplant clinics in Belgium and France. We excluded patients who were in the first two months post-transplantation and/or had a urinary catheter. Asymptomatic participants who had a urine culture with one organism isolated at ≥ 105 CFU/mL were asked to provide a confirmatory urine specimen. Asymptomatic bacteriuria was defined per Infectious Diseases Society of America guidelines. RESULTS We screened 500 consecutive kidney transplant recipients. Overall, the prevalence of asymptomatic bacteriuria was 3.4% (17/500 patients). It was similarly low among kidney transplant recipients who were between 2 and 12 months after transplantation (1.3%, 1/76 patients) and those who were farther after transplantation (3.8%, 16/424 patients: p = 0.49). Asymptomatic bacteriuria was significantly associated with female gender (risk ratio 3.7, 95% CI 1.3-10.3, p = 0.007) and older age (mean age: 61 ± 12 years [bacteriuric participants], versus 53 ± 15 years [non-bacteriuric participants], p = 0.03). One participant's colistin-resistant Escherichia coli isolate carried the globally disseminated mcr-1 gene. CONCLUSIONS Among kidney transplant recipients who are beyond the second month post-transplant, the prevalence of asymptomatic bacteriuria is low. Further studies are needed to ascertain the cost-effectiveness of a screen-and-treat strategy for asymptomatic bacteriuria in this population.

Abstract
AIM Examine the incidence of suspected and proven infections, the range of infections, antimicrobial use and hospital admissions in kidney transplant recipients (KTx) in southern Tasmania. METHODS An audit of the medical records of KTx managed by the Royal Hobart Hospital for the period 1 January 2015 to 31 December 2016. Data were collected on positive microbiological investigations, antimicrobial use and hospital admissions. RESULTS Of the 151 evaluable KTx, there were 339 episodes of suspected infection in 95 (63%) patients with a preponderance of urinary tract infections. Overall, these 95 KTx received a total of 249 courses of antimicrobials, with predominantly monotherapy (n = 101, 65%). There were 11 vaccine preventable infections, including herpes zoster (n = 7), Influenza A (n = 3) and invasive pneumococcal disease (n = 1). Hospitalization was required for 50 infectious episodes, for a total of 227 admitted bed days (median 4; interquartile range 2-7; range 1-18 days). CONCLUSION In conclusion, episodes of infection, hospitalization, antimicrobial use and development of multi-resistant organisms are common following kidney transplantation in this southern Tasmanian cohort. This study has identified several areas of focus for improved patient care including antimicrobial management of urinary tract infections, implementation of programmes to vaccinate KTx prior to transplantation, and development of transplantation specific antimicrobial stewardship programmes.

Abstract
BACKGROUND AND OBJECTIVES AKI is associated with progression of CKD. Little is known about AKI after kidney transplantation in pediatric recipients. We aim to describe the epidemiology, risk factors, consequences, and outcomes of AKI in this population. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS We performed a retrospective longitudinal analysis of pediatric kidney transplant recipients followed at The Hospital for Sick Children (Toronto, Canada) from 2001 to 2012. AKI was defined as an increase in serum creatinine ≥1.5 times baseline, and a rise of serum creatinine ≥1.25 but <1.5 times baseline defined subacute AKI. RESULTS Of 179 children, 122 were eligible for analysis. At baseline (3 months post-transplant), median age of the children was 13 years old (interquartile range, 9-16 years old), and 53% had CKD stage 2. Congenital anomalies of the kidney and urinary tract accounted for 46% of children. Over the study period (12 years), the incidence of AKI was 37% (n=45 children), and 65% (79 children) experienced subacute AKI. Twenty-seven percent (33 children) did not develop AKI or subacute AKI. The main causes of AKI were infections other than urinary tract infections, rejection, and urinary tract infections. In a multivariable Poisson regression analysis, independent risk factors for AKI included younger age, girls, grafts from deceased donors, and lower baseline eGFR. AKI was significantly associated with lower long-term GFR and graft loss independent of rejection episodes. Moreover, subacute AKI was associated with progression of CKD. CONCLUSIONS AKI and subacute AKI were common after pediatric kidney transplantation, and they were associated with graft loss, lower eGFR, and more rapid progression of CKD.

Abstract
Background Reducing post-operative infections among kidney transplant patients is critical to improve long-term outcomes. With shifting disease demographics and implementation of new transplantation protocols, frequent evaluation of infection rate and type is necessary. Objective Our objectives were to assess the incidence and types of post-operative infections in kidney transplant recipients at a large tertiary-care facility and determine sample sizes needed for future intervention trials. Design Retrospective cohort study. Setting The Ottawa Hospital, Ottawa, Ontario. Patients Adult kidney transplant patients, N = 142. Measurements Demographic data, transplant protocol, infections up to 2 years following transplantation. Methods Infections within 2 years following transplantation in all kidney transplant recipients between January 2011 and December 2012 were reviewed. Sample sizes were determined using all-cause infection rates and infection-free survival data. Results Of 142 patients, 44 (31.0%) had at least one infection. The incidence of infection was 36.2 per 100 patient-years by 2 years post-transplant. A total of 32 (22.5%) patients had 56 infection-related hospitalizations with 73.2% occurring in the first year. In the first 2 years, urinary tract infections had the highest incidence (18.1 per 100 patient-years) followed by skin (3.9 per 100 patient-years), cytomegalovirus (3.9 per 100 patient-years), and bacteremia (3.9 per 100 patient-years). Results indicate that 206 patients per study arm would be needed to show a 30% reduction in the 2-year incidence of infection post-transplantation. Limitations Infection rates may be slightly underestimated due to the relatively short 2-year follow-up; however, the highest infection-risk period was captured within this time frame. Conclusions Infections post-kidney transplant are still common, particularly urinary tract infections. They are associated with significant morbidity and hospitalization. Given the feasible sample sizes calculated in this study, intervention trials are indicated to further reduce infection rates within the first 2 years post-kidney transplantation.

Abstract
INTRODUCTION Recurrent urinary tract infections (UTI) are a common clinical problem in kidney transplant recipients. Due to the complex urological anatomy derived from the implantation of the kidney graft, the spectrum of the disease and the broad underlying pathophysiological mechanisms. Recurrent UTI worsen the quality of life, decrease the graft survival and increase the costs of kidney transplantation. Areas covered: In this review, we describe the definitions, clinical characteristics, pathophysiological mechanisms and microbiology of recurrent urinary tract infections in kidney transplantations. The actual published literature on the management of recurrent urinary tract infections is based on case series, observational cohorts and very few clinical trials. In this review, the available evidence is compiled to propose evidence-based strategies to manage these complex cases. Expert commentary: The management of recurrent urinary tract infections in kidney transplant patients requires a proper diagnosis of the underlying mechanism. Early identification of structural or functional urological abnormalities, potentially amenable for surgical correction, is crucial for a successful management. The use of antibiotics to prevent recurrent infections should be carefully evaluated to avoid side effects and emergence of antibiotic-resistant microorganisms.

Abstract
BACKGROUND Antibiotics are frequently prescribed to kidney transplant (KTX) recipients in the outpatient setting, but there are limited data assessing the safety and outcomes associated with this practice. OBJECTIVE The primary objective of this study was to describe ambulatory antibiotic prescribing in a large cohort of adult KTX recipients. The secondary objective was to assess the outcomes associated with potentially unsafe antibiotic use in this population. METHODS National Veterans Health Administration data compiled between 2001 and 2010 were used to conduct a pharmacovigilance assessment of antibiotic prescribing, excluding intravenous agents, antifungals, antivirals, and prophylactic regimens. Multivariable Cox proportional hazard regression was used to determine the impact of safe and potentially unsafe antibiotic use on time to event for graft loss. RESULTS Among 5130 KTX recipients and 30 127 patient-years of follow-up, 14 259 antibiotic courses were prescribed at a rate of 0.47 courses per patient-year. Transplant or nephrology providers prescribed 24.8% of courses. Overall, 608 courses (4.3%) in 311 patients (6.1%) were considered potentially unsafe for dosages in disagreement with recommended adjustments for renal function, interaction with immunosuppressive regimens, and other pertinent safety concerns. After adjusting for baseline characteristics, unsafe antibiotic use was associated with a 40% higher risk of graft loss (adjusted hazard ratio = 1.40; 95% CI = 1.03-1.89; P = 0.030) compared with safe use. CONCLUSIONS AND RELEVANCE Although unsafe antibiotic prescribing was uncommon, it was associated with increased risk of graft loss. Prospective research is needed to elucidate whether the driver of poor outcomes is the safety of the antibiotic prescription or fragmented care.

Abstract
INTRODUCTION Rehospitalization early post-kidney transplant is common and has a negative impact in morbidity, graft survival, and health costs. Infection is one the most common causes, and identifying the risk factors for early readmission due to infectious complications may guide a preventive program and improve outcome. The aim of this study was to evaluate the incidence, characterize the population, and identify the risk factors associated with early readmission for infectious complications post-kidney transplantation. METHODS We performed a retrospective cohort study of all the kidney transplants performed during 2015. The primary outcome was readmission in the first 3 months post-transplant due to infectious causes defined by clinical and laboratory parameters. RESULTS We evaluated 141 kidney transplants; 71% of subjects were men, with an overall mean age of 50.8 ± 15.4 years. Prior to transplant, 98% of the patients were dialysis dependent and 2% underwent pre-emptive living donor kidney transplant. The global readmission rate was 49%, of which 65% were for infectious complications. The most frequent infection was urinary tract infection (n = 28, 62%) and the most common agent detected by blood and urine cultures was Klebsiella pneumonia (n = 18, 40%). The risk factors significantly associated with readmission were higher body mass index (P = .03), diabetes mellitus (P = .02), older donor (P = .007), and longer cold ischemia time (P = .04). There were 3 graft losses, but none due to infectious complications. CONCLUSION There was a high incidence of early rehospitalization due to infectious complications, especially urinary tract infections to nosocomial agents. The risk factors identified were similar to other series.

Abstract
BACKGROUND Infections are a major cause of morbidity and mortality in kidney allograft recipients. In this post hoc analysis of a randomized clinical trial which tested the effect of denosumab on bone mineral density, we assessed the impact of this drug on the incidence and severity of infections in the first year after kidney transplantation. METHODS In this clinical trial, we randomized 90 de novo kidney transplant recipients shortly after transplantation to either denosumab on top of standard treatment (calcium and vitamin D) (n = 46), or to standard treatment alone (n = 44). Among all adverse events, we analyzed all infections that occurred within the first year after transplantation, and compared their incidence and severity in both groups. RESULTS Overall, we identified more infections (n = 146) in the denosumab group than in the control group (n = 99). The most common infections were urinary tract infection (cystitis) (34.9% vs 25.2%), cytomegalovirus viremia (17.8% vs 24.2%), flu-like syndrome (11.6% vs 14.1%), polyoma (BK) viremia (8.2% vs 11.1%), and herpes simplex infections (5.5% vs 4.0%). Episodes of urinary tract infection (cystitis) occurred more often in the denosumab than in the control group (51 vs 25 episodes in 24 vs 11 patients, P = 0.008), whereas episodes of transplant pyelonephritis or urosepsis were not more frequent (3 vs 5 episodes). CONCLUSIONS This post hoc analysis reveals that treatment with denosumab to prevent bone loss in first-year kidney transplant recipients was associated with more frequent episodes of urinary tract infections, whereas other infections occurred with similar frequency in both treatment groups.

Abstract
Renal transplantation is an effective and commonly performed procedure for end-stage renal disease. Urinary tract infections are a major cause of morbidity and mortality in renal transplant patients. As data on postrenal transplant urinary tract infections from the Indian subcontinent are limited, the present study was conducted to estimate the burden of urinary tract infections in this vulnerable group of patients. This was a prospective study on patients undergoing renal transplantation in 2014 at our tertiary hospital in South India with a follow-up of 2 years to evaluate the risk factors for urinary tract infections. The prevalence of urinary tract infections was 41.9% with a male preponderance of 76.9%. Mean age of the 31 patients was 32.4 ± 10.2 years (range: 16-55 years). Gram-negative bacilli were the most common isolates with Escherichia coli being the predominant pathogen (53.3%). All the infections occurred within 1 year of transplantation with delayed graft function (P < 0.001; confidence interval [CI]: 29.0-96.3) and prolonged hospital stay (P = 0.0281; CI: 42.1-99.6) being the significant risk factors for acquiring urinary tract infections. Carbapenemase production was noted in 33.3% of isolates and all the Gram-negative organisms isolated in the 1st month of transplantation were carbapenem-resistant (CR) E. coli. The high rate of carbapenem-resistant organisms in the early posttransplant period is a point of concern, especially with cadaver transplants. Infection control practices and catheter care need to be strictly monitored to minimize the risk for UTI in the immediate posttransplant period.

Abstract
To inform the UK antimicrobial resistance strategy, a risk assessment was undertaken of the likelihood, over a five-year time-frame, of the emergence and widespread dissemination of pan-drug-resistant (PDR) Gram-negative bacteria that would pose a major public health threat by compromising effective healthcare delivery. Subsequent impact over five- and 20-year time-frames was assessed in terms of morbidity and mortality attributable to PDR Gram-negative bacteraemia. A Bayesian approach, combining available data with expert prior opinion, was used to determine the probability of the emergence, persistence and spread of PDR bacteria. Overall probability was modelled using Monte Carlo simulation. Estimates of impact were also obtained using Bayesian methods. The estimated probability of widespread occurrence of PDR pathogens within five years was 0.2 (95% credibility interval (CrI): 0.07–0.37). Estimated annual numbers of PDR Gram-negative bacteraemias at five and 20 years were 6800 (95% CrI: 400–58,600) and 22,800 (95% CrI: 1500–160,000), respectively; corresponding estimates of excess deaths were 1900 (95% CrI: 0–23,000) and 6400 (95% CrI: 0–64,000). Over 20 years, cumulative estimates indicate 284,000 (95% CrI: 17,000–1,990,000) cases of PDR Gram-negative bacteraemia, leading to an estimated 79,000 (95% CrI: 0–821,000) deaths. This risk assessment reinforces the need for urgent national and international action to tackle antibiotic resistance.

Abstract
Background: One of the main causes of adverse complications following kidney transplantation is urinary tract infection (UTI). This study was done to define the incidence rate, clinical profiles, causative microorganisms, and UTI risk factors among kidney transplant recipients in Mashhad city. Materials and Methods: In this retrospective study, we perused medical files of 247 kidney recipients who underwent transplant surgery at Mashhad University Montaserie Hospital, during 2012–2014. All patients were followed for UTI during the 1st year after surgery. Results: 75 episodes of UTI developed by 152 pathogens in 56 (22.7%) of patients during 1-year follow-up. 26.6% of total UTIs were diagnosed within the 1st month after transplantation. The most frequently isolated uropathogens were Escherichia coli (55.3%, n = 84). The high rate of candiduria (8.5%) was observed, too. Conclusion: UTI is known as one of the hospitalization reasons in kidney transplantation recipients. Defining appropriate antibiotic prophylaxis against bacterial and fungal agents and early removal of urethral catheter are suggested to decrease posttransplantation complications.

Abstract
OBJECTIVES Renal transplant is one of the best ways to extend life of patients in the end stage of renal disease. Infections are significant causes of morbidity and mortality after renal transplant. The aim of this study was to evaluate frequency, risk factors, causative pathogens, and clinical manifestations in renal transplant recipients from Mashhad City during the first year after transplant. MATERIALS AND METHODS This research was conducted at Montaserie Hospital of Mashhad University of Medical Sciences from March 2013 to July 2015. All studied cases were followed for 1 year. In this retrospective study, our study cohort comprised 193 kidney transplant recipients, including 118 male (61.1%) and 75 female (38.9%) patients, with mean age of 34.4 ± 12.2 years. Of the total patients, 58 received kidneys from living donors (30.1%) and 135 received kidneys from deceased donors (69.9%). RESULTS We found that 151 infectious episodes had occurred in 96 patients. The most common infectious site involved the urinary tract (39.1%). Escherichia coli was the most frequently isolated pathogen. The only significant infection risk factor to affect transplant outcomes during the first year was age. CONCLUSIONS Infections are highly prevalent during the first year after transplant. Prevention and effective antibiotic therapy can reduce the related adverse effects.

Abstract
BACKGROUND We assessed the effect of hepatitis C seropositivity on the percentage of various T-cells in living donor renal transplant recipients (LDRTRs) and their association with intercurrent infections post renal transplantation (post-Tx). METHODS One hundred and thirty-three matching LDRTRs [A (seronegative) (68 patients) and B (seropositive) (65 patients) by ELISA] were studied prospectively 10 days, 6 months and 12 months post-Tx for intercurrent infections, acute rejection and T-cell% by flow cytometry. RESULTS CD4(+), CD8(+), CD4/CD8 were significantly higher 10 days post-Tx in Group B compared to Group A, p < 0.001. A significant increase in CD8% was seen 6-month post-Tx among Group B compared to Group A. No difference was detected between groups in (CD4(+), CD8(+), CD4/CD8, CD3-CD16/65(+)%), rate and severity of intercurrent infection, rate of acute rejection, 12 months post-Tx. A significantly higher rate of severe infections particularly urinary tract infections (UTI) was noted in Group B compared to Group A the first 3 months post-Tx particularly in those who received the combination of antithymocyte globulin (ATG) or basiliximab, tacrolimus, steroids, mycophenolate mofetil (MMF). CD4(+)% correlated negatively with intercurrent infections in Group B 6 months post-Tx. CONCLUSION HCV(+) patients are more prone to intercurrent infections the first 3 months post-Tx. Infection rate correlates positively with pre-transplant HCV seropositivity and immunosuppressive regimen.

Abstract
Background: Urinary tract infection (UTI) as an important infection in the setting of renal transplantation carries the high mortality and morbidity rate. Thus, the prevention of this infection should receive higher priority. However, bacterial resistance to antibiotics is on the rise, with limited data to guide prophylaxis. The purpose of this study was to compare the effect of sulfamethoxazole-trimethoprim (SMZ/TMP) and SMZ/TMP plus ciprofloxacin for prophylaxis of UTI in renal transplant recipients. Materials and Methods: In a clinical trial study, 50 patients were included and divided into two groups of 25 using block randomization. Patients in Group I received prophylactic SMZ/TMP and those in Group II received ciprofloxacin plus SMZ/TMP. The incidence of UTI in the two groups at 1, 3, and 6 months after transplantation was evaluated. This study was registered in Iranian Registry of Clinical Trial (IRCT number: IRCT 2015120823743N1). Results: Of the 61 patients older than 18 years at the time of transplantation, 50 were included. UTI was documented in 8 patients (32%) in Group I and 3 (12%) in Group II (P = 0.026). The average time for the development of the first case of infection was the same for both groups (P = 0.241), and it was at its maximum in the 1st month. Urinary infections caused by Escherichia coli, the dominant strain, were the same in both groups (P = 0.673). Conclusions: Our study shows that the addition of 1 month course of ciprofloxacin lowered the incidence of UTI. More studies are needed to confirm the efficacy of this approach.

Abstract
Kidney transplantation (KT) is the best available therapy for patients with end-stage renal disease. Infectious complications are a common cause of morbidity and mortality. In this study, we evaluated the risk factors and outcomes of infectious complications in the first year after transplantation. This is a retrospective and observational study of kidney transplant recipients at Ankara University's Ibni Sina Hospital between January 2009 and August 2013. A total of 206 kidney transplant recipients were evaluated. In 129 patients, 298 infectious episodes occurred: 55 (26.7%) had 1; 33 (16%) 2; 19 (9.2%) 3; 7 (3.4%) 4; and 15 (7.3%) had 5 or more infectious episodes. The most common bacterial infection was urinary tract infection (128, 42.9%). Only 4 urinary tract infection episodes (3.1%) were associated with bacteriemia. Seventeen patients (5.7%) had bacteremia. Viral infections after transplantation were CMV infection (10.1%), BK virus infection (5.7%), and zona zoster (1.1%). Deceased donor kidney transplantation was the independent risk factor. Mean follow-up period was 66 months and was the same for the patients with and without infections. There was no significant difference in 5-year survival and creatinine levels at the last follow-up (logrank P = .409). Infections are the second most common cause of mortality in KT patients. The successful treatment of these complications and effective prophylaxis may decrease these complications.

Abstract
Urinary tract infection (UTI) is the most common complication following kidney transplantation (KT), which could result in losing the graft. This study aims to identify the prevalence of bacterial UTI among KT recipients in Yemen and to determine the predisposing factors associated with post renal transplantation UTI. A cross sectional study included of 150 patients, who underwent KT was conducted between June 2010 and January 2011. A Morning mid-stream urine specimen was collected for culture and antibiotic susceptibility test from each recipient. Bacterial UTI was found in 50 patients (33.3%). The prevalence among females 40.3% was higher than males 29%. The UTI was higher in the age group between 41-50 years with a percentage of 28% and this result was statistically significant. Predisposing factors as diabetes mellitus, vesicoureteral reflux, neurogenic bladder and polycystic kidney showed significant association. High relative risks were found for polycystic kidney = 13.5 and neurogenic bladder = 13.5. The most prevalent bacteria to cause UTI was Escherichia coli represent 44%, followed by Staphylococcus saprophyticus 34%. Amikacin was the most effective antibiotic against gram-negative isolates while Ciprofloxacin was the most effective antibiotic against Staphylococcus saprophyticus. In conclusion, there is high prevalence of bacterial UTI among KT recipients in Yemen. Diabetes mellitus, vesicoureteral reflux, neurogenic bladder, polycystic kidney and calculi were the main predisposing factors.

Abstract
OBJECTIVE It has been reported in many studies that one of the main factors influencing morbidity and mortality in patients receiving transplants is infection after transplantation. PATIENTS AND METHODS The study included 190 adult patients undergoing orthotopic liver transplantation (OLT) between September 2001 and December 2007. All the patients were followed prospectively for infections from the OLT date and during the first 4 weeks after surgery. Immunosuppression consisted of steroids and tacrolimus. Antimicrobial prophylaxis included piperacillin/tazobactam, fluconazole, and selective bowel decontamination (SBD) was performed. Samples of clinical materials were investigated for microbiological cultures. The micro-organisms were cultured and identified in accordance with standard bacteriological procedures. Susceptibility testing was performed using Clinical and Laboratory Standards Institute procedures. RESULTS From 190 OLT recipients, 2213 clinical samples were obtained for microbiological examination. Positive cultures were found in 27.2% (n = 603) of all samples tested; 1252 strains were collected. Gram-positive bacteria were found in 64.1% (n = 802), Gram-negative bacteria were found in 31.6% (n = 396), and fungal strains were isolated in 4.3% (n = 54). Surgical site specimens (n = 1031) were obtained from 190 recipients during the first month after transplantation. Positive cultures accounted for 29.2% (n = 301) of all samples tested. Among the isolated microbial strains (n = 677), most common were Gram-positive bacteria (73.7%; n = 499). Gram-negative bacteria comprised 25.1% (n = 170). There were fungal strains in 1.2% (n = 8). There were 539 urine specimens. Positive cultures accounted for 16.7% (n = 90) of those. Among the isolated microbial strains (n = 210), most common were Gram-negative bacteria (62.4%; n = 131). Gram-positive bacteria comprised 28.6% (n = 60) and fungi 9% (n = 19). There were 549 blood specimens. Positive cultures were found in 30.6% (n = 168) of all samples tested. Among the isolated microbial strains (n = 263), most common were Gram-positive bacteria in 72.3% (n = 190); Gram-negative bacteria were found in 26.2% (n = 69), and fungal strains were isolated in 1.5% (n = 4). There were 69 respiratory tract specimens. Positive cultures were found in 46.4% (n = 32) of all samples tested. Among the isolated microbial strains (n = 84), most common were Gram-positive bacteria (51.2%; n = 43); Gram-negative bacteria comprised 27.4% (n = 23) and fungi 21.4% (n = 18). CONCLUSIONS (1) Surgical site samples were predominated samples after LTx. (2) Our study showed Gram-positive bacteria were 64.1% (n = 802), Gram-negative bacteria, 31.6% (n = 396) and fungal strains isolated in 4.3% (n = 54). (3) The increased proportion of isolates of multi-drug-resistant bacterial strains (methicillin resistant coagulase negative Staphylococcus, vancomycin-resistant Enterococcus, high-level aminoglycoside resistance, and extended- spectrum β-lactamase).

Abstract
BACKGROUND Infections remain serious complications in solid-organ transplant recipients, despite professional medical care, the introduction of new immunosuppressive drugs, and treatment that decreases the risk of infections. METHODS The study covered 295 adult patients undergoing kidney transplantation (KTx) between September 2001 and December 2007. All the patients were followed prospectively for infections from the KTx date and during the first 4 weeks after surgery. Samples of clinical materials were investigated for microbiological cultures. The microorganisms were cultured and identified in accordance with standard bacteriological procedures. Susceptibility testing was carried out through the use of Clinical and Laboratory Standards Institute procedures. RESULTS From 295 KTx recipients, 1073 clinical samples were taken for microbiological examination. Positive cultures were 26.9% (n = 289) of all samples tested; 525 strains were collected. Gram-positive bacteria were isolated in 52.2% (n = 274), Gram-negative bacteria were isolated in 40.8% (n = 214), and fungal strains were isolated in 7% (n = 37). Urine specimens (n = 582) were obtained from 84.5% of 245 recipients during the first month after transplantation. Among the isolated bacterial strains (n = 291), the most common were Gram-negative bacteria (56.4%). Gram-positive bacteria comprised 35.7%; fungal strains were found in 23 cases (7.9%). In surgical site specimens (n = 309), Gram-positive bacteria (72.1%) were the most common. Gram-negative bacteria comprised 24.4%. In blood specimens (n = 138), Gram-positive bacteria (81.6%) were the most common. Gram-negative bacteria comprised 15.8%; fungi were isolated in 2.6%. In respiratory tract specimens (n = 13), among the isolated bacterial strains (n = 8), the most common were Gram-positive bacteria (57.1%). Gram-negative bacteria comprised 14.3%; fungi were isolated in 28.6%. CONCLUSIONS Urine samples were predominantly positive after KTx. Our study showed Gram-positive bacteria in 52.2% after kidney transplantation. The proportion of isolates of multi-drug-resistant bacterial strains (MRCNS, vancomycin-resistant strains, high-level aminoglycoside-resistant strains, extended-spectrum beta-lactamase producers, and high-level aminoglycoside-resistant strains) was increased. These data indicate the need for strict adherence to infection control procedures in these patients.

Abstract
Surgical site infections (SSIs) and early urinary tract infections (UTIs) are well recognized postoperative kidney transplant complications. These complications seldom lead to graft loss, although they may result in significant morbidity with prolonged hospitalization. Thus, perioperative antibiotic prophylaxis (PAP) has traditionally been used in this setting. Between April 1988 and December 2012, we identified 1000 kidney transplant recipients (33 from living donors) who underwent prophylaxis with ceftriaxone before the surgical procedure. A retrospective analysis was conducted to evaluate both the incidence rate and outcome of SSIs and UTIs. Recipients who developed SSIs were also assessed to identify risk factors and potential correlations with different immunosuppressive regimens. A total of 20 SSIs (2%) and 93 UTIs (9.3%) were observed. The most significant risk factor for SSIs was urine leak (15.38%; odds ratio [OR], 12.3; P < .0001) followed by sirolimus-based maintenance immunosuppression therapy (5%; OR, 2.97; P = .04) and induction therapy with either antithymocyte globulin or basiliximab (3.18%; OR, 3.45; P = .01). Sex was identified as the only risk factor for UTI (female vs male, 17.1% vs 4.6%; P < .0001). We believe universal ceftriaxone-based prophylaxis is useful for preventing SSIs and UTIs, considering its effectiveness and safety profile.

Abstract
Infections remain a common complication of solid organ transplantation. Early postoperative infections remain a significant cause of morbidity and mortality in solid organ transplant (SOT) recipients. Although significant effort has been made to understand the epidemiology and risk factors for early nosocomial infections in other surgical populations, data in SOT recipients are limited. A literature review was performed to summarize the current understanding of pneumonia, urinary tract infection, surgical-site infection, bloodstream infection, and Clostridium difficult colitis, occurring within the first 30 days after transplantation.

Abstract
BACKGROUND The burden of enterococcal infections has increased over the last decades with vancomycin-resistant enterococci (VRE) being a major health problem. Solid organ transplantation is considered as a risk factor. However, little is known about the relevance of enterococci in solid organ transplantation recipients in areas with a low VRE prevalence. METHODS We examined the epidemiology of enterococcal events in patients followed in the Swiss Transplant Cohort Study between May 2008 and September 2011 and analyzed risk factors for infection, aminopenicillin resistance, treatment, and outcome. RESULTS Of the 1234 patients, 255 (20.7%) suffered from 392 enterococcal events (185 [47.2%] infections, 205 [52.3%] colonizations, and 2 events with missing clinical information). Only 2 isolates were VRE. The highest infection rates were found early after liver transplantation (0.24/person-year) consisting in 58.6% of Enterococcus faecium. The highest colonization rates were documented in lung transplant recipients (0.33/person-year), with 46.5% E. faecium. Age, prophylaxis with a betalactam antibiotic, and liver transplantation were significantly associated with infection. Previous antibiotic treatment, intensive care unit stay, and lung transplantation were associated with aminopenicillin resistance. Only 4/205 (2%) colonization events led to an infection. Adequate treatment did not affect microbiological clearance rates. Overall mortality was 8%; no deaths were attributable to enterococcal events. CONCLUSIONS Enterococcal colonizations and infections are frequent in transplant recipients. Progression from colonization to infection is rare. Therefore, antibiotic treatment should be used restrictively in colonization. No increased mortality because of enterococcal infection was noted.

Abstract
AIM Infectious complications after renal transplantation (RT) are associated with significant morbidity. They continue to be the most frequent cause of mortality. We investigated the incidence of infections, the causative pathogens, and risk factors contributing to this complication during the first year. PATIENTS AND METHODS We included demographic and clinical data of the 124 patients who underwent RT in our hospital from December 2004 to June 2010. for statistical analysis. RESULTS Fifty (40.3%) RT recipients developed 80 episodes of infection: urinary tract (n = 68; 85%), intraabdominal (n = 4; 5%), surgical wound (n = 3; 3.8%), or central venous catheter (n = 3; 4%). Eight (10%) were bacteremic. The most commonly isolated bacteria scene (76/80) was Escherichia coli (n = 43; 56.5%) followed by Klebsiella spp. (n = 10; 13.2%) and Pseudomonas spp. (n = 10; 13.2%). Cytomegalovirus infection was detected in 2 recipients; fungal and mycobacterial infections, in no case. It was noteworthy that 52.8% of E. coli and Klebsiella spp. produced extended-spectrum beta-lactamase. Ninety percent of infections developed within 6 months after transplantation. When we compared infected versus noninfected cases, the presence of a double J catheter was the most significant risk factor (P = .018; odds ratio [OR] = 0.234; 95% confidence interval [CI] = 0.070-0.781). In contrast to the initial years after the start of RT in our hospital the incidence of infection decreased over time together with a decrease number and durations of catheterization (P = .008; OR = 2.707; 95% CI = 1.292-5.672). CONCLUSIONS Urinary tract infections were the predominant problem with most isolates resistant to extended-spectrum antibiotics. Therefore, invasive catheters and prophylactic antibiotics should not be used for longer than necessary and infection control measures implemented to decrease the incidence of infections and bacterial resistance.
