Perioperative Antibiotic Prophylaxis

Abstract Background: Infections in kidney transplant recipients are particularly challenging owing to the immunosuppressive treatment, usually long history of chronic illness, comorbidities and prior exposures to antibiotics. Among the most common complications early after surgery are surgical site infections. The aim of this study was to identify risk factors and evaluate epidemiological data regarding surgical site infections. Moreover, we were able to compare the current results with historical data from our institution when different perioperative antibiotic prophylaxis was practiced.Methods: We conducted a retrospective case-control study in a group of 254 deceased donor renal graft recipients transplanted in a single Central European institution. We evaluated epidemiological findings and resistance patterns of pathogens causing surgical site infections. We used multivariable logistic regression to determine risk factors for surgical site infections.Results: We revealed no differences in baseline characteristics between patients with and without surgical site infections. Ten surgical site infections (3.9%) were diagnosed (six superficial incisional, two deep incisional, and two organ/space). Eight species (19 strains) were identified, most of which were multi-drug resistant (63%). The most common was extended-spectrum β-lactamase producing Klebsiella pneumoniae (26%). We showed that statistically significant differences were present between reoperated and non-reoperated patients (adjusted odds ratio: 6.963, 95% confidence interval: 1.523-31.842, P = .012).Conclusions: Reoperation is an individual risk factor for surgical site infection after kidney transplantation. According to our experience, cefazolin-based prophylaxis can be safe and is associated with relatively low prevalence of surgical site infections.

ABSTRACT Objectives: to assess the prevalence of colonization and infection by multidrug-resistant bacteria in patients undergoing kidney transplantation and identify the rate of infection, morbidity and mortality and associated risk factors. Methods: a prospective cohort of 200 randomly included kidney transplant recipients. Epidemiological surveillance of the studied microorganisms was carried out in the first 24 hours and 7 days after transplantation. Results: ninety (45%) patients were considered colonized. Female sex, hypertension and diabetes (p<0.005), dialysis time (p<0.004), length of stay after transplantation, delayed renal function, and length of stay were identified as risk factors. The microorganisms were isolated from surgical site, bloodstream and urinary tract infections. Conclusions: colonization by resistant microorganisms in kidney transplant patients was frequent and risk factors associated with infection were identified. The results should guide the care team in order to minimize morbidity and mortality related to infectious causes in this population.

Abstract Background The management of meningitis requires the prompt introduction of high-dose probabilistic anti-infectious therapy. The literature reporting on meningitis in kidney transplant recipients (KTR) is scarce and no recommendation exists for this specific population. Methods We retrospectively included all adult KTRs diagnosed with meningitis (cerebro-spinal fluid (CSF) cell count >10/mm3 or positive fungal antigen or direct examination) between 2007 and 2018 in 16 French hospitals. Clinical, biological, and therapeutic data, and 1-year kidney and patient survival were collected. Results Meningitis occurred in 134 KTRs (mean age 57+/11.8 years, 56% male), after a median time of 27 months (IQR 8–65); 25% of patients received an immunosuppressive treatment before kidney transplantation, induction treatment included lymphocyte-depleting antibodies in 63%, and 53% presented diabetes (34% before and 19% after the transplantation). The etiologies included Cryptococcus neoformans (30%), Herpesviridae (22%, including Varicella-Zoster Virus 15%), idiopathic forms (11%), Gram-negative bacilli (8% of which 20% produced an extended spectrum β-lactamase), %), infusion of intravenous immunoglobulins (6%), post-transplant lymphoproliferative disorders (5%), Aspergillus fumigatus (4%), Listeria monocytogenes (4%), Enterovirus (4%), and Mycobacterium tuberculosis (3%). The most common symptoms were fever (82.5%), headaches (75%), encephalitis (55%), and convulsion (22.5%). CSF hypercellularity (found in 92% of the cases) was lymphocytic in 65% of the cases and neutrophilic in 35%. Initial anti-infectious therapy was inappropriate in 27% of the cases. One-year patient, graft, and death-censored graft survival rates were 84%, 76%, and 89%, respectively. Conclusion Meningitis after kidney transplantation encompasses a wide range of causes, with C. neoformans and VZV explaining more than 50% of the cases. Gram-negative bacilli are the most represented bacteria with a high rate of antimicrobial resistance. Treatment guidelines should be reconsidered in the specific population of KTRs as the etiology greatly differs from what is observed in the general population.

Purpose: Kidney Transplant Recipients (KTRs) tend to develop infections with characteristic epidemiology, presentation and outcome. While infective endocarditis (IE) is among such complications in KTRs, literature is scarce. We describe the presentation, epidemiology, and factors associated with IE in KTRs. Methods: We performed a retrospective case/control study which included patients from two centers. First episodes of definite or possible IE (Duke criteria), in adult KTRs from January 2007 to December 2018 were included, as well as two controls per case, and followed until December 31 2019. Clinical, biological, and microbiological data and the outcome were collected. Survival was studied using the Kaplan-Meier method. Finally, we searched for factors associated with the onset of IE in KTRs by the comparison of cases and controls. Results: Seventeen cases and 34 controls were included. IE was diagnosed after a mean delay of 78 months after KT, mostly on native valves of the left heart only. Pathogens of digestive origin were most frequently involved (six Enterococcus spp, three Streptococcus gallolyticus and one Escherichia coli), followed by Staphylococci (three cases of S. aureus and S. epidermidis each). Among the risk factors evaluated only age was significantly associated with the occurrence of IE in our study (63.8 years for cases vs. 55.6 years for controls, P=0.03) Patient and death-censored graft survival were greatly diminished five years after IE compared to controls being 50.3% vs. 80.6% (p&lt;0.003) and 29.7% vs. 87.5% (p&lt;0.002), respectively. Conclusion: IE in KTRs is a disease that carries significant risks both for the survival of the patient and the transplant.

Abstract Background and Aims BK virus nephropathy occurs in up to 10% of kidney transplant recipients and can result in graft loss. The reactivation of BK virus is largely asymptomatic, and routine surveillance especially in the first 12-24 months after transplant is necessary for early recognition and intervention. Reduced immunosuppression and antiviral treatment in the early stages may be effective in stopping BK virus replication. This study is designed to investigate the effect of management in immunosuppressive therapy on BK virus titers and graft functions in our kidney transplant group. Method A total of 370 kidney transplant recipients between the ages of 18-69 years and receiving a triple immunosuppressive therapy (Tacrolimus+Mycophenoloic Acid+Prednisolone) were included in the study. Demographic characteristics, BK virus titers, serum creatinine and immunosuppressive drug (Tacrolimus, Everolimus) levels were measured at regular intervals in the first 24 months. Among these patients 43 of them were found to have BK virus positivity. At the time of the detection of BK virus positivity, patients were divided into three groups regarding the change in the immunosuppressive protocols: Group I: Tacrolimus + Everolimus + Prednisolone, Group II: Everolimus + Prednisolone, Group III: Tacrolimus + Prednisolone. BK virus titers and graft functions of all three groups were compared with each other. SPSS 15 for Windows was used for statistical analysis. Results The mean age of the patients was 45.3 years, and the mean duration of transplantation was 16.3 months at the time of the BK virus positivity. During the follow-up, mean Tacrolimus levels were found to be in their highest value (14.1 ng/mL) in the posttransplant three months while BK virus titer reached the highest value (1.1x106 copies/ml) in the posttransplant seven to nine months. Increased creatinine values two months after BK virus positivity were strongly correlated (p = 0.02, p = 0.008, p = 0.05, p = 0.002 at 6th, 9th, 12th and 24th months, respectively). A significant decrease in BK virus titers was observed in all three groups due to reductions in immunosuppressive treatment protocol (p = 0.005, p = 0.003, p = 0.028, in groups I, II, III respectively). Conclusion Our study favors the benefits of the prospective screening for BK virus to identify early viral replication, permit intervention, and prevent progression to nephropathy or allograft loss. The best studied treatment for BK viremia and nephropathy is careful reduction of immunosuppression
