Abstract
In this review, we discuss stool donor screening considerations to mitigate potential risks of pathogen transmission through fecal microbiota transplant (FMT) in solid organ transplant (SOT) recipients. SOT recipients have a higher risk for Clostridioides difficile infection (CDI) and are more likely to have severe CDI. FMT has been shown to be a valuable tool in the treatment of recurrent CDI (RCDI); however, guidelines for screening for opportunistic infections transmitted through FMT are underdeveloped. We review reported adverse effects of FMT as they pertain to an immunocompromised population and discuss the current understanding and recommendations for screening found in the literature while noting gaps in research. We conclude that while FMT is being performed in the SOT population, typically with positive results, there remain many unanswered questions which may have major safety implications and warrant further study.

Abstract
BACKGROUND There is limited knowledge about risk factors for Clostridioides difficile infection (CDI) and recurrent CDI in solid organ transplant (SOT) recipients. METHODS A case-control study of CDI in SOT recipients compared with controls (SOT recipients who did not present CDI). RESULTS Sixty-seven patients from 1089 SOT recipients (6.2%) suffered at least one episode of CDI. The mean age was 55 ± 12 years and 20 cases (69%) were men. The accumulated incidence was 8% in liver transplantation, 6.2% in lung transplantation, 5.4% in heart transplantation, and 4.7% in kidney transplantation. Twenty-nine cases (43.3%) were diagnosed during the first 3 months after SOT. Forty-one cases (61.2%) were hospital acquired. Thirty-one patients with CDI presented with mild-moderate infection (46.3%), 30 patients with severe infection (44.8%), and 6 patients with severe-complicated disease (9%). Independent variables found to be related with CDI were hospitalization in the previous 3 months (odds ratio: 2.99; [95% confidence interval 1.21-7.37]) and the use of quinolones in the previous month (odds ratio: 3.71 [95% confidence interval 1.16-11.8]). Eleven patients (16.4%) had at least one recurrence of CDI. Previous treatment with amoxicillin-clavulanate, severe-complicated index episode, and high serum creatinine were associated with recurrent CDI in the univariant analysis CONCLUSIONS: Liver transplant recipients presented the highest incidence of CDI among SOT recipients. Risk factors for CDI were hospitalization in the previous 3 months and the use of quinolones in the previous month.

Early Clostridioides difficile infection characterizations, risks, and outcomes in allogeneic hematopoietic stem cell and solid organ transplant recipients. Transpl Infect Dis 2021; 24:e13720. [PMID: 34455662 DOI: 10.1111/tid.13720] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2021] [Revised: 07/12/2021] [Accepted: 08/16/2021] [Indexed: 01/21/2023]
Abstract
BACKGROUND Clostridioides difficile infection (CDI) frequently complicates allogeneic hematopoietic stem cell (allo-HCT) and solid organ transplantation (SOT). METHODS We retrospectively analyzed risk factors and outcomes of CDI occurring within 30 days of transplant. RESULTS Between March 2010 and June 2015, 466 allo-HCT and 1454 SOT were performed. The CDI cumulative incidence (95% CI) was 10% (8-13) and 4% (3-5), following allo-HCT and SOT, respectively (p < .01), occurring at a median (range) 7.5 days (1-30) and 11 (1-30), respectively (p = .18). In multivariate analysis, fluoroquinolones use within 14 days pre-transplantation was a risk factor for CDI following allo-HCT (HR 4.06 [95% CI 1.31-12.63], p = .02), and thoracic organ(s) transplantation was a risk factor for CDI following SOT (HR 3.03 [95% CI 1.31-6.98]) for lung and 3.90 (1.58-9.63) for heart and heart/kidney transplant, p = .02. Compared with no-CDI patients, the length of stay (LOS) was prolonged in both allo-HCT (35 days [19-141] vs. 29 [13-164], p < .01) and SOT with CDI (16.5 [4-101] vs. 7 [0-159], p < .01), though not directly attributed to CDI. In allo-HCT, severe acute graft-versus-host disease (aGVHD) occurred more frequently in patients with CDI (33.3% vs. 15.8% without CDI, p = .01) and most aGVHD (87.5%) followed CDI. Non-relapse mortality or overall survival, not attributed to CDI, were also similar in both allo-HCT and SOT. CONCLUSIONS Early post-transplant CDI is frequent, associated with fluoroquinolones use in allo-HCT and the transplanted organ in SOT, and is associated with longer LOS in both the groups without difference in survival but with increased aGVHD in allo-HCT.

Abstract
BACKGROUND The association between Clostridioides difficile colonization and C. difficile infection (CDI) is unknown in solid-organ transplant (SOT) patients. We examined C. difficile colonization and healthcare-associated exposures as risk factors for development of CDI in SOT patients. METHODS The retrospective study cohort included all consecutive SOT patients with at least 1 screening test between May 2017 and April 2018. CDI was defined as the presence of diarrhea (without laxatives), a positive C. difficile clinical test, and the use of C. difficile-directed antimicrobial therapy as ordered by managing clinicians. In addition to demographic variables, exposures to antimicrobials, immunosuppressants, and gastric acid suppressants were evaluated from the time of first screening test to the time of CDI, death, or final discharge. RESULTS Of the 348 SOT patients included in our study, 33 (9.5%) were colonized with toxigenic C. difficile. In total, 11 patients (3.2%) developed CDI. Only C. difficile colonization (odds ratio [OR], 13.52; 95% CI, 3.46-52.83; P = .0002), age (OR, 1.09; CI, 1.02-1.17; P = .0135), and hospital days (OR, 1.05; 95% CI, 1.02-1.08; P = .0017) were independently associated with CDI. CONCLUSIONS Although CDI was more frequent in C. difficile colonized SOT patients, the overall incidence of CDI was low in this cohort.

Abstract
BACKGROUND Screening for Clostridioides difficile (CD) colonization can be performed using molecular testing to identify the presence of microbial DNA of the toxin gene. Colonization rates for hospitalized patients are as high as 20% and may be considerably higher in solid organ transplant (SOT) recipients. Treatment for CD should be based on clinical disease and not colonization, yet clinicians may misinterpret a positive CD screen resulting in overtreatment. OBJECTIVES The objective of this analysis is to determine how often positive CD screens resulted in inappropriate treatment with oral vancomycin. METHODS Clostridioides difficile screens were performed using the Xpert C difficile assay (Cepheid), a nucleic acid amplification testing method utilizing polymerase chain reaction (PCR), on peri-rectal swabs for newly admitted patients. This was a single-center cohort study of adult patients with CD screens hospitalized between July 2015 and November 2018. The primary outcome was the rate of inappropriate oral vancomycin treatment in all patients and in SOT recipients, defined as therapy in the absence of diarrhea. RESULTS Of the 47 076 total CD screens reviewed, 1,921 were positive. In the SOT cohort, 58 of 329 screens were positive (4.1% vs 17.9%, P < .01). Of all patients with a positive CD screen, 20.1% (386/1921) were treated with oral vancomycin within 48 hours of swab collection. In the SOT cohort, 39.6% (23/58) with positive CD screens were treated with oral vancomycin within 48 hours. Of the SOT patients who received oral vancomycin, 39% (9/23) did not have true CD infection. CONCLUSION Solid organ transplant recipients were more likely to have CD colonization detected by peri-rectal screening than the general inpatient population. SOT and non-SOT patients were treated with oral vancomycin at similar rates in response to the positive screen. Nearly half of the oral vancomycin use in SOT recipients was likely overtreatment, but this finding is limited by the low number of patients in this cohort.

Abstract
BACKGROUND Asymptomatic C. difficile colonization is believed to predispose to subsequent C. difficile infection (CDI). While emerging insights into the role of the commensal microbiota in mediating colonization resistance against C. difficile have associated CDI with specific microbial components, corresponding prospectively collected data on colonization with C. difficile are largely unavailable. METHODS C. difficile status was assessed by GDH EIA and real-time PCR targeting the toxin A (tcdA) and B (tcdB) genes. 16S V3 and V4 gene sequencing results from fecal samples of patients tested positive for C. difficile were analyzed by assessing alpha and beta diversity, LefSe, and the Piphillin functional inference approach to estimate functional capacity. RESULTS 1506 patients were recruited into a prospective observational study (DRKS00005335) upon admission into one of five academic hospitals. 936 of them provided fecal samples on admission and at discharge and were thus available for longitudinal analysis. Upon hospital admission, 5.5% (83/1506) and 3.7% (56/1506) of patients were colonized with toxigenic (TCD) and non-toxigenic C. difficile (NTCD), respectively. During hospitalization, 1.7% (16/936) acquired TCD. Risk factors for acquisition of TCD included pre-existing lung diseases, lower GI endoscopy and antibiotics. Species protecting against hospital-related C. difficile acquisition included Gemmiger spp., Odoribacter splanchnicus, Ruminococcus bromii and other Ruminococcus spp.. Metagenomic pathway analysis identified steroid biosynthesis as the most underrepresented metabolic pathway in patients who later acquire C. difficile colonization. CONCLUSIONS Gemmiger spp., Odoribacter splanchnicus, Ruminococcus bromii and other Ruminococci were associated with a decreased risk of C. difficile acquisition.

Abstract
Pediatric recipients of SOT have a significantly increased risk of Clostridiodes (formerly Clostridium) difficile infection (CDI), which is associated with adverse outcomes after SOT. Alterations to the intestinal microbiota community structure increase the risk of CDI. FMT is a safe and effective treatment for recurrent CDI in immunocompetent children and adults. While there are increasing data that FMT in immunosuppressed patients is safe and effective without increased risk of infection, data regarding safety and efficacy of FMT in children after SOT are limited. To our knowledge, we report the youngest immunocompromised patient to undergo FMT and the third overall case of FMT in a child after HTx. Our patient presented with five episodes of rCDI in 6 months, and 16S rRNA genetic analysis revealed significant loss of overall microbiota community structure and diversity prior to FMT compared with a donor and a healthy, age-matched control. After FMT, marked and prolonged (at least 16 months) shifts in the recipient microbiota community structure and diversity were evident, approaching that of donor and healthy, age-matched control. FMT was well tolerated, restored microbial diversity without any graft or transplant complications, and prevented further rCDI episodes after more than 4 years of follow-up.

Abstract
BACKGROUND Clostridioides difficile infection (CDI) is common after solid organ transplant (SOT) and is associated with high morbidity and mortality. METHODS We assessed incidence, risk factors, and outcomes of CDI among SOT patients at a large multi-organ transplant center. Multivariable logistic regression was used to identify risk factors for initial and recurrent CDI. RESULTS A total of 2622 SOT patients were included. 224 (8.5%) had CDI 1 year post-SOT. The highest incidence of CDI was among pancreas recipients (12.5%) followed by lung (11.7%), liver (11.0%), heart (10.8%), and kidney (5.8%). Median time to CDI was 56 days (range 2-354) post-SOT. About 64% of patients had severe CDI. About 56.3% were treated with metronidazole, 13.8% with oral vancomycin, and 28.6% with both. About 28.6% of patients had recurrent CDI. In multivariable modeling, lung transplant recipient status was the only significant predictor of recurrent CDI (OR 4.97, 95% CI 2.11-11.78, P < .001) controlling for age, severe CDI, and pre-SOT CDI. Post-SOT CDI nearly doubled the risk of mortality at one year, in particular among those with severe CDI. CONCLUSIONS In summary, CDI is highly prevalent, occurs early in the post-transplant period, usually severe, with a high rate of recurrence, and associated with increased mortality within 1 year after transplant. The early post-transplant period may be a crucial window to reduce CDI rates.

Abstract
These updated guidelines from the American Society of Transplantation Infectious Diseases Community of Practice address the prevention and management of Clostridium difficile infection in solid organ transplant (SOT) recipients. Clostridioides (formerly Clostridium) difficile infection (CDI) is among the most common hospital acquired infections. In SOT recipients, the incidence of CDI varies by type and number or organs transplanted. While a meta-analysis of published literature found the prevalence of postoperative CDI in the general surgical population to be approximately 0.51%, the prevalence of CDI that is seen in the solid organ transplant population ranges from a low of 3.2% in the pancreatic transplant population to 12.7% in those receiving multiple organ transplants. There are no randomized, controlled trials evaluating the management of CDI in the SOT population. Herein is a review and summary of the currently available literature that has been synthesized into updated treatment guidelines for the management of CDI in the SOT population.

Abstract
BACKGROUND Clostridioides (Clostridium) difficile infection (CDI) in pediatric solid organ transplant (SOT) recipients is a growing problem, though CDI risk factors in this population are poorly understood. Our objective was to characterize CDI risk factors in pediatric SOT recipients. METHODS This retrospective case-control study, performed at a single freestanding academic children's hospital, included all SOT recipients age 1-22 years who were tested for C. difficile by toxin B gene PCR between August 2009 and August 2017. CDI risk factors were assessed by comparing PCR-positive and PCR-negative cases by generalized linear mixed models. RESULTS Between August 2009 and August 2017, 409 SOTs were performed of which 138 (33.7%), 134 (32.8%), 131 (32.0%), and 6 (1.5%) were kidney, liver, heart, and small intestine transplants, respectively. Of 205 SOT recipients were tested for CDI, with 723 C. difficile PCR tests performed among these patients. 68/205 (33%) patients developed CDI at least once during the study period. Median (interquartile range) time to diagnosis of first CDI following SOT was 8.9 (1.2, 19.6) months. CDI was independently associated with calcineurin inhibitor use at time of C. difficile testing (odds ratio [OR] 2.38, 95% confidence interval [CI] 1.08, 5.24, P = 0.03) and systemic antibiotic exposure within 30 days of C. difficile testing (OR 1.74, 95% CI 1.08, 2.79, P = 0.02). CONCLUSIONS CDI is a common, relatively late post-transplant complication and independently associated with calcineurin inhibitor and systemic antibiotic exposure. The potential impact of specific immunosuppressive drug and antibiotic selection on CDI risk reduction requires further investigation.

Abstract
Renal transplantation is a vital treatment option in children with ESRD with more than 10,000 pediatric kidney transplants and survival rates of greater than 80% at 10 years post-transplant in the USA alone. Despite these advances, infection remains a significant cause of morbidity in pediatric recipients. Screening potential organ donors and recipients is imperative to identify and mitigate infectious risks in the transplant patient. Despite the unique risks of each patient, the timing of many infections post-transplant is predictable. In early post-transplant infections (within 30 days), bacterial and fungal pathogens predominate with donor-derived events and nosocomial infections. In the intermediate period (31-180 days after transplant), latent infections from donor organs, such as EBV and CMV, develop. Late infections occurring > 180 days after the transplant can be due to latent pathogens or community-acquired organisms. Approaching an infectious evaluation in a pediatric kidney recipient requires finesse to diagnose and treat this vulnerable population in a timely manner. The following article highlights the most relevant and common infections including clinical manifestations, risk factors, diagnostic techniques, and treatment options.

Abstract
BACKGROUND Clostridioides difficile infection (CDI) is a frequent complication of solid organ transplantation, especially in the early post-transplantation period. Overdiagnosis of CDI is likely common in hospitals using nucleic acid amplification testing (NAAT), potentially leading to unnecessary iatrogenesis and cost. Recently, multiple studies have shown that computerized clinical decision support (CCDS)-based interventions can significantly reduce inappropriate C. difficile testing and healthcare facility-onset CDI events across hospitals and health systems. We aimed to determine if a CCDS-based intervention could reduce C. difficile testing and surveillance infection events among recent solid organ transplant recipients, a population at high risk for CDI. We also sought to determine the safety of the CCDS intervention. MATERIAL AND METHODS Quasi-experimental census-adjusted interrupted time-series analyses were performed retrospectively to examine testing and CDI events pre- and post-intervention. Mortality and readmissions rates were also examined. RESULTS A significant 33% relative reduction in tests and a nonsignificant trend towards fewer CDI events were observed following the intervention, without significant differences in mortality or 30-day readmission. A review of patients with positive C. difficile NAATs after prevented tests revealed no specific adverse events attributable to a possible delay in CDI diagnosis. CONCLUSIONS CCDS may be a helpful and safe adjunctive strategy to reduce unnecessary testing in accordance with guideline recommendations among solid organ transplant recipients.

Abstract
Clostridium difficile infection is a significant cause of morbidity and mortality in solid organ transplant recipients. Risk factors in this population include frequent hospitalizations, receipt of immunosuppressive agents, and intestinal dysbiosis triggered by several factors, including exposure to broad-spectrum antimicrobials. The incidence and potential for significant adverse outcomes among solid organ transplant recipients with C difficile infection highlight the evolving need for strategic C difficile infection risk factor modification and novel approaches to disease management in this patient population. This review focuses on current concepts related to the prevention and treatment of C difficile infection in solid organ transplant recipients.

Abstract
Clostridium difficile infection (CDI) is a leading cause of infectious diarrhea in solid organ transplant recipients (SOT). We aimed to assess incidence, risk factors, and outcome of CDI within the Swiss Transplant Cohort Study (STCS). We performed a case-control study of SOT recipients in the STCS diagnosed with CDI between May 2008 and August 2013. We matched 2 control subjects per case by age at transplantation, sex, and transplanted organ. A multivariable analysis was performed using conditional logistic regression to identify risk factors and evaluate outcome of CDI. Two thousand one hundred fifty-eight SOT recipients, comprising 87 cases of CDI and 174 matched controls were included. The overall CDI rate per 10 000 patient days was 0.47 (95% confidence interval ([CI] 0.38-0.58), with the highest rate in lung (1.48, 95% CI 0.93-2.24). In multivariable analysis, proven infections (hazard ratio [HR] 2.82, 95% CI 1.29-6.19) and antibiotic treatments (HR 4.51, 95% CI 2.03-10.0) during the preceding 3 months were independently associated with the development of CDI. Despite mild clinical presentations, recipients acquiring CDI posttransplantation had an increased risk of graft loss (HR 2.24, 95% CI 1.15-4.37; P = .02). These findings may help to improve the management of SOT recipients.

Abstract
BACKGROUND Solid organ transplant recipients are especially vulnerable to Clostridium difficile infection (CDI) due to cumulative risk factors including increased exposure to healthcare settings, persistent immunosuppression, and higher rates of antimicrobial exposure. We aimed to identify risk factors associated with CDI development in kidney transplant recipients including implications of immunosuppressive therapies and acid-suppressing agents. METHODS This was a single-center, non-interventional, retrospective case-control study of adult subjects between June 1, 2009 and June 30, 2013. During this time, 728 patients underwent kidney transplantation. Overall, 22 developed CDI (cases) and were matched 1:3 with 66 controls. Cases and controls were also matched for induction agent, kidney allograft type (living or deceased), and time from transplant to CDI result (±60 days). RESULTS The majority of subjects received a deceased donor kidney (77.3%) and basiliximab induction therapy (86.4%). The overall CDI incidence was 3%. Factors independently associated with CDI were average tacrolimus trough (AOR = 1.25, 95% CI = 1.00-1.56, P = .048) and antibiotic exposure for urinary tract infections (UTI) (AOR = 4.17, 95% CI = 1.12-15.54, P = .034). Proton pump inhibitor use was not associated with CDI (OR = 0.81, 95% CI = 0.29-2.29, P = .691). CONCLUSION Maintaining a clinically appropriate tacrolimus trough and judicious antibiotic use and selection for UTI treatment could potentially reduce CDI in the kidney transplant population.

Abstract
BACKGROUND Clostridium difficile infection (CDI) is a common complication of lung and allogeneic hematopoietic cell (HCT) transplant, but the epidemiology and outcomes of CDI after transplant are poorly described. METHODS We performed a prospective, multicenter study of CDI within 365 days post-allogeneic HCT or lung transplantation. Data were collected via patient interviews and medical chart review. Participants were followed weekly in the 12 weeks post-transplant and while hospitalized and contacted monthly up to 18 months post-transplantation. RESULTS Six sites participated in the study with 614 total participants; 4 enrolled allogeneic HCT (385 participants) and 5 enrolled lung transplant recipients (229 participants). One hundred and fifty CDI cases occurred within 1 year of transplantation; the incidence among lung transplant recipients was 13.1% and among allogeneic HCTs was 31.2%. Median time to CDI was significantly shorter among allogeneic HCT than lung transplant recipients (27 days vs 90 days; P = .037). CDI was associated with significantly higher mortality from 31 to 180 days post-index date among the allogeneic HCT recipients (Hazard ratio [HR] = 1.80; P = .007). There was a trend towards increased mortality among lung transplant recipients from 120 to 180 days post-index date (HR = 4.7, P = .09). CONCLUSIONS The epidemiology and outcomes of CDI vary by transplant population; surveillance for CDI should continue beyond the immediate post-transplant period.

Abstract
As immunosuppressive therapy has evolved over the years, rejection rates in solid organ transplant have declined, but infections remain a significant cause of morbidity and mortality in this population. Prophylaxis against bacterial, viral, and fungal infections is often used to prevent infection from common pathogens during high-risk periods. As an integral part of the multidisciplinary medical team, it is important that nurses caring for transplant recipients be familiar with methods to detect and prevent infectious diseases in this population. This article presents a review of risk factors for and prevalence of common infectious pathogens, as well as important considerations regarding prophylactic medications in solid organ transplant recipients.

Abstract
OBJECTIVE We evaluated whether a short-term course with synbiotics may lower plasma p-Cresol concentrations in kidney transplant patients (KTRs) who accumulate this uremic toxin both because of increased production by their dysbiotic gut microbiome and because of reduced elimination by the transplanted kidneys. METHODS Thirty-six KTRs (29 males, mean age 49.6 ± 9.1 years) with transplant vintage > 12 months, stable graft function, and no episode of acute rejection or infection in the last 3 months were enrolled in this single-center, parallel-group, double-blinded, randomized (2:1 synbiotic to placebo) study. Synbiotic (Probinul Neutro, CadiGroup, Rome, Italy) or placebo was taken at home for 30 days, as 5 g powder packets dissolved in water three times a day far from meals. The main outcome measure was the decrease in total plasma p-Cresol measured by high-performance liquid chromatography at baseline and after 15 and 30 days of placebo or synbiotic treatment. RESULTS After 15 and 30 days of treatment, plasma p-Cresol decreased by 40% and 33% from baseline (both p < 0.05), respectively, in the synbiotic group, whereas it remained stable in the placebo group. After 30 days of treatment, no significant change was observed in either group in renal function, glycemia, plasma lipids, or albumin concentration. Treatment was well tolerated and did not induce any change in stool characteristics. CONCLUSION The results of this pilot study suggest that treatment with synbiotics may be effective to lower plasma p-Cresol concentrations in KTRs. Prospective larger scale, longer term studies are needed to establish whether cardiovascular prognosis could also be improved with this nutritional intervention.

Abstract
PURPOSE OF REVIEW Clostridium difficile infection (CDI) is a major healthcare-associated infection that causes significant morbidity and an economic impact in the United States. In this review, we provide an overview of Clostridium difficile infection in solid organ transplant recipients with an emphasis on recent literature. RECENT FINDINGS C. difficile in solid organ transplant population has unique risk factors. Fecal microbiota transplantation has shown favorable results in treatment of recurrent C. difficile in this population. Preliminary data from animal studies suggests excellent efficacy with immunization against C. difficile toxins. SUMMARY Over the last decade, number of individuals receiving solid organ transplants has increased exponentially making peri-transplant complications a common occurrence.C. difficile is a frequent cause of morbidity in solid organ transplant recipients. Early and accurate diagnosis of C. difficile requires a stepwise approach. Differentiating between asymptomatic carriage and infection is a diagnostic challenge. Microbial diversity is inversely proportional to risk of C. difficile infection. Antimicrobial stewardship programs help to retain microbial diversity in individuals susceptible to CDI. Recurrent or relapsing C. difficile infection require fecal microbiota transplantation for definitive cure.

Abstract
BACKGROUND Diarrhea is a common condition after solid organ transplant (SOT); Clostridium difficile-associated colitis (CDAC) is one of the most common infections after SOT. We documented previously that some types of enteritis are associated with an elevation of tacrolimus (TAC) trough concentrations by interfering with the drug's complex metabolism. PATIENTS AND METHODS Tacrolimus concentrations of 25 SOT recipients including 12 renal and 13 liver recipients before, during, and after CDAC were analyzed retrospectively. RESULTS Median age of the 25 patients was 54 y (range, 36-71), there were 15 males and 10 females. Clostridium difficile-associated colitis developed at a median of 55 d (range 2-4551) post-SOT. Median TAC concentrations prior to the outbreak of CDAC were 6.9 ng/mL (range, <1.5-17.2), 5.6 ng/mL (range, <1.5-13.2) during diarrhea, and 7.4 ng/mL (range, <1.5-24.3) after resolution of diarrhea (p > 0.05, NS). Treatment of CDAC consisted of metronidazole for 14 d in all cases. All patients recovered from CDAC but seven patients had CDAC relapse. CONCLUSIONS In contrast to other types of infectious diarrhea such as rotavirus enteritis and cryptosporidiosis, CDAC is not associated with an increase in TAC concentrations. This is because C. difficile causes primarily colitis as opposed to other organisms, which are associated with enteritis.

Abstract
BACKGROUND Clostridium difficile is a major cause of diarrhea in thoracic organ transplant recipients. We investigated the epidemiology, risk factors, and outcome of Clostridium difficile infection (CDI) in heart and heart-lung transplant (HT) recipients. METHODS This is a retrospective study from 2004 to 2013. CDI was defined by diarrhea and a positive toxigenic C. difficile in stool measured by toxin enzyme immunoassay (2004-2006) or polymerase chain reaction (2007-2013). Cox proportional hazards regression was used to model the association of risk factors with time to CDI and survival with CDI following transplantation. RESULTS There were 254 HT recipients, with a median age of 53 years (IQR, 45-60); 34% were female. During the median follow-up of 3.1 years (IQR, 1.3-6.1), 22 (8.7%) patients developed CDI. In multivariable analysis, risk factors for CDI were combined heart-lung transplant (HR 4.70; 95% CI, 1.30-17.01 [P=.02]) and retransplantation (HR 7.19; 95% CI, 1.61-32.12 [P=.01]). Acute cellular rejection was associated with a lower risk of CDI (HR 0.34; 95% CI, 0.11-0.94 [P=.04]). CDI was found to be an independent risk factor for mortality (HR 7.66; 95% CI, 3.41-17.21 [P<.0001]). CONCLUSIONS Clostridium difficile infection after HT is more common among patients with combined heart-lung and those undergoing retransplantation. CDI was associated with a higher risk of mortality in HT recipients.

Abstract
The complex relationship between microbiota, human physiology, and environmental perturbations has become a major research focus, particularly with the arrival of culture-free and high-throughput approaches for studying the microbiome. Early enthusiasm has come from results that are largely correlative, but the correlative phase of microbiome research has assisted in defining the key questions of how these microbiota interact with their host. An emerging repertoire for engineering the microbiome places current research on a more experimentally grounded footing. We present a detailed look at the interplay between microbiota and host and how these interactions can be exploited. A particular emphasis is placed on unstable microbial communities, or dysbiosis, and strategies to reestablish stability in these microbial ecosystems. These include manipulation of intermicrobial communication, development of designer probiotics, fecal microbiota transplantation, and synthetic biology.

Abstract
BACKGROUND The incidence of Clostridium difficile infection (CDI) is increasing in the pediatric population. Pediatric recipients of solid organ transplantation (SOT) may be at a higher risk for CDI in part because of chemotherapy and prolonged hospitalization. METHODS We utilized data from the Healthcare Cost and Utilization Project Kids' Inpatient Database to study the incidence and outcomes related to CDI as a complicating factor in pediatric recipients of SOT. RESULTS Our results demonstrate that hospitalized children with SOT have increased rates of infection, with the greatest risk for younger children with additional comorbidities and severe illness. The type of transplanted organ affects the risk for CDI, with the lowest incidence observed in renal transplant patients. CONCLUSION The occurrence of CDI in the pediatric SOT population contributes to a greater length of stay and higher hospital charges. However, CDI is not an independent predictor of increased in- hospital mortality in these patients.

Abstract
Infections are an important cause of morbidity and mortality in solid organ transplant recipients. Consequently, infection prevention is an essential component of any organ transplant program. Given their frequent and often prolonged contact with the healthcare system, solid organ transplant recipients are at high risk for healthcare-associated infections, including those caused by antibiotic-resistant organisms. In this chapter we review several different healthcare-associated infections of importance to transplant recipients, including those caused by bacterial, viral, and fungal organisms. We also describe infection prevention and control strategies applicable to this patient population. These practices focus on clinical interventions and environmental controls designed to prevent the spread of potentially pathogenic organisms in the healthcare setting. We also describe post-exposure interventions applicable to solid organ transplant recipients exposed to potential pathogens in order to reduce their risk of subsequent infection.

Abstract
CDIs are on the rise in both hospital and community settings in adults and children. Children with cancer or a history of HSCT or SOT appear to be at higher risk for primary disease, recurrent disease, and severe outcomes when compared to children with other comorbidities. The reasons for this are not clear and no studies to date have analyzed risk factors for CDI in pediatric transplant patients. Colonization rates in children with cancer and a transplant history are also high. Determining which children are colonized with Clostridium difficile and symptomatic from another source vs. symptomatic from CDI is difficult and a clinical conundrum for the transplant physician. The use of fecal transplantation for severe or rCDI is likely safe and effective in the immunosuppressed pediatric cancer or transplant patient, but this will need to be more thoroughly studied in this patient population.

Abstract
PURPOSE OF REVIEW Clostridium difficile infection (CDI) is one of the most common healthcare-associated infections, and the threat associated with CDI continues to grow in all patient populations. There is increasing evidence that CDI has a substantial impact on the morbidity and mortality in solid organ transplant (SOT) recipients. Furthermore, new diagnostic and treatment options and strategies for CDI have emerged over the last decade. The purpose of this review is to provide a general understanding of CDI and its evidence-based diagnosis and management strategies, with a focus on SOT recipients. RECENT FINDINGS The incidence and severity of CDI have significantly increased since the year 2000. Studies have identified novel risk factors for CDI, and a new epidemic strain, the NAP1/BI/027, has emerged. Despite the development of newer testing methods and approaches, including nucleic acid amplification tests and testing algorithms, the optimal method for diagnosing CDI is an area of controversy. New agents for treating CDI are being developed, and the use of fecal microbiota transplantation to treat recurrent CDI in SOT recipients is also evolving. SUMMARY CDI is a significant problem for SOT recipients. Further studies on diagnostic and therapeutic strategies with a focus on SOT recipients are needed to further improve patient outcomes.

Abstract
PURPOSE To identify reversible risk factors for Clostridium difficile infection (CDI) after kidney transplantation (KT) that could lead to a reduction in its incidence and associated complications. METHODS We performed a single-center case-control study in which 41 patients undergoing KT between February 2009 and July 2013 who developed a first episode of post-transplant CDI were included as cases. Patients transplanted at the same calendar day (± 2 weeks) as each case with no evidence of CDI and comparable risk exposure period were chosen as controls (2:1 ratio). Serum immunoglobulin and complement levels were systematically measured at baseline and months 1 and 6 after transplantation. RESULTS Multivariate regression analysis identified age-adjusted Charlson comorbidity index (odds ratio [OR] per unitary increment 1.31; P value = 0.043), delayed graft function (OR 2.76; P value = 0.039), prior cytomegalovirus (CMV) disease (OR 6.85; P value = 0.011) and prior acute graft rejection (OR 5.92; P value = 0.008) as risk factors for post-transplant CDI. Cases with their first episode of CDI occurring beyond the first month were more likely to have IgG hypogammaglobulinemia (HGG) at month 1 (P value = 0.002), whereas cases with CDI beyond the sixth month were more likely to have HGG of any class at month 6 (P value = 0.003). Poor outcome (graft loss and/or all-cause mortality) was more common among cases (adjusted hazard ratio 5.69; P value = 0.001). CONCLUSION The occurrence of CDI exerts a detrimental effect on graft and patient outcome. Post-transplant HGG was a potentially modifiable risk factor for CDI in KT recipients.

Abstract
The objective of this study was to evaluate the frequency of Clostridium Difficile Infection (CDI) among kidney transplant recipients and describe the clinical picture in correlation with the presence of certain risk factors. We included kidney transplant recipients with a functioning graft, who were admitted during the period 1/2012-12/2013, and patients with ESRD who were admitted to undergo Kidney Transplantation (KTx) from a deceased or a living donor in the same period. Patients were screened following clinical indication of gastrointestinal infection. CDI diagnosis was based on a positive stool sample for CD toxins and stool culture. Within the period 2012-2013, we recorded 24 cases of CDI in 19 patients, accounting for a frequency of 5.4% of CDI in our population. In addition to diarrhea, 63.15% of the patients presented with fever, 31.25% with anorexia, while abdominal pain was a rare symptom (0.53%). None of the patients had ileus, bowel obstruction or megacolon. Fourteen patients (73.7%) had a history of recent exposure (15 days) to antimicrobial agents prior to the evolution of CDI symptoms. A relapse of the CDI infection was identified in five cases. CDI infection is a significant factor of morbidity in patients with KTx and should be considered in the clinical setting of diarrhea, even in cases with no exposure to antibiotic agents.

Abstract
Clostridium difficile is a bacterial enteric pathogen, which causes clinical disease among solid organ transplant (SOT) recipients. This large, single-center, retrospective study describes incidence, demographics, and impact of C. difficile infection (CDI) among adult SOT recipients, cardiac (n=5), lung (n=14), liver (n=9), renal (n=26), and multiorgan (n=9) patients transplanted and diagnosed with CDI (geneB PCR) between 9/2009 and 12/2012. The overall incidence of CDI in our population during the 40-month period of study was 4%. CDI incidence among cardiac, lung, liver, and renal transplant recipients was 1.9%, 7%, 2.7%, and 3.2%, respectively (P=0.03 between organ-types). Median time from transplant to CDI for all was 51 (14-249) days, with liver recipients having the shortest time to infection, median 36 (15-101) days, and lung recipients having a longer time to infection, median 136 (29-611) days. Antibiotic exposure within 3 months of CDI was evident in 45 of the 63 (71%) patients in this study, 80%, 79%, 100%, 58%, and 67% of cardiac, lung, liver, renal, and multiorgan transplant recipients, respectively. Most patients (83%) were hospitalized within the 3 months preceding CDI. Recipients were followed for a median time of 23 (16-31) months; at the time of last follow-up, 83% of allografts were functioning, and 86% of patients were alive. One death and 1 graft failure were causally related to CDI. CDI had an overall incidence of 4%; clinicians should have heightened awareness for CDI, especially among patients receiving antibiotics, with increased monitoring and aggressive management of CDI.

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
Clostridium difficile infection (CDI) presents a rapidly evolving challenge in the battle against hospital-acquired infections. Recent advances in CDI diagnosis and management include rapid changes in diagnostic approach with the introduction of newer tests, such as detection of glutamate dehydrogenase in stool and polymerase chain reaction to detect the gene for toxin production, which will soon revolutionize the diagnostic approach to CDI. New medications and multiple medical society guidelines have introduced changing concepts in the definitions of severity of CDI and the choice of therapeutic agents, while rapid expansion of data on the efficacy of fecal microbiota transplantation heralds a revolutionary change in the management of patients suffering multiple relapses of CDI. Through a comprehensive review of current medical literature, this article aims to offer an intensive review of the current state of CDI diagnosis, discuss the strengths and limitations of available laboratory tests, compare both current and future treatments options and offer recommendations for best practice strategies.

Abstract
Fecal microbiota transplantation (FMT) has been shown to be safe and efficacious in individuals with refractory Clostridium difficile. It has not been widely studied in individuals with immunosuppression due to concerns about infectious complications. We describe two solid organ transplant recipients, one lung and one renal, in this case report that both had resolution of their diarrhea caused by C. difficile after FMT. Both recipients required two FMTs to achieve resolution of their symptoms and neither had infectious complications. Immunosuppressed individuals are at high risk for acquisition of C. difficile and close monitoring for infectious complications after FMT is necessary, but should not preclude its use in patients with refractory disease due to C. difficile. Sequential FMT may be used to achieve cure in these patients with damaged microbiota from antibiotic use and immunosuppression.

Abstract
Knowledge of outcomes of Clostridium difficile infection (CDI) in solid organ transplant (SOT) recipients is limited. To evaluate this population, we undertook a retrospective cohort study of all recipients of kidney and liver transplants diagnosed with CDI at a single center over 14 yr. Data pertaining to all episodes of CDI were collected. Multivariate analysis using logistic regression was performed to determine independent predictors of clinical cure. Overall, 170 patients developed 215 episodes of CDI. Among these patients, 162 episodes (75%) were cured, and in 103 episodes (48%), patients were cured within 14 d. In a multivariate analysis, lack of clinical cure at 14 d was predicted by recurrent episode (0.21, 95% CI 0.06-0.72, p = 0.0128), treatment with vancomycin (OR 0.27, 95% CI 0.1-0.74, p = 0.011), vasopressor support (OR 0.23, 95% CI 0.07-0.76, p = 0.0161), and CDI before the year 2004 (OR 0.44, 95% CI 0.2-0.98, p = 0.0446). The latter three factors are likely markers for severity of illness. In this cohort, 13 patients (8%) died during hospitalization, and 49 patients (29%) died within one yr. No deaths were attributed to CDI. Recurrent episode was a major predictor of treatment failure, suggesting that research into development of therapeutic options for recurrent disease is needed.

Abstract
The portal vein carries blood from the gastrointestinal tract to the liver and in so doing carries microbes as well. The liver may therefore be involved in infections with a myriad number of microbial organisms. While some of these infections most commonly occur in the immunocompromised host, others affect the immune competence. Hepatic infections may be primary in nature or secondary, as part of systemic or contagious disease. The purpose of this chapter is to provide a brief overview of the various infections of the liver in the pediatric patient.

Abstract
Critical care of the general surgical patient requires synthesis of the patient's physiology, intraoperative events, and preexisting comorbidities. Evaluating an abdominal solid-organ transplant recipient after surgery adds a new dimension to clinical decisions because the transplanted allograft has undergone its own physiologic challenges and now must adapt to a new environment. This donor-recipient interaction forms the foundation for assessment of early allograft function (EAF). The intensivist must accurately assess and support EAF within the context of the recipient's current physiology and preexisting comorbidities. Optimizing EAF is essential because allograft failure is a significant predictor of recipient morbidity and mortality.

Abstract
OBJECTIVE To provide a comprehensive review of the literature as it relates to diarrhea in solid organ transplant (SOT) recipients. In this article, we review the epidemiology, pathogenesis, clinical manifestations, diagnosis and management of diarrhea in SOT recipients and discuss recent advances and challenges. METHODS Two investigators conducted independent literature searches using PubMed, Web of Science, and Scopus until January 1st, 2013. All databases were searched using a combination of the terms diarrhea, solid organ transplant, SOT, transplant associated diarrhea, and transplant recipients. Articles that discussed diarrhea in SOT recipients were reviewed and relevant cross-references also read and evaluated for inclusion. Selection bias could be a possible limitation of the approach used in selecting or finding articles for this article. FINDINGS Post-transplant diarrhea is a common and distressing occurrence in patients, which can have significant deleterious effects on the clinical course and well-being of the organ recipient. A majority of cases are due to infectious and drug-related etiologies. However, various other etiologies including inflammatory bowel disease must be considered in the differential diagnosis. A step-wise, informed approach to post-transplant diarrhea will help the clinician achieve the best diagnostic yield. The use of diagnostic endoscopy should be preceded by exclusion of an infectious or drug-related cause of diarrhea. Empiric management with antidiarrheal agents, probiotics, and lactose-free diets may have a role in managing patients for whom no cause can be determined even after an extensive investigation. CONCLUSIONS Physicians should be familiar with the common etiologies that result in post-transplant diarrhea. A directed approach to diagnosis and treatment will not only help to resolve the diarrhea but also prevent potentially life-threatening consequences including loss of the graft as well. Prospective studies are required to determine the etiology of post-transplant diarrhea in different clinical and geographic settings.

Abstract
Modern post-transplant care pathways commonly encompass periods of critical care support. Infectious events account for many of these interactions making critical care physicians integral members of multidisciplinary transplant teams. Despite continuing advances in clinical care and infection prophylaxis, the morbidity and mortality attributable to infection post-transplant remains considerable. Emerging entities constantly add to the breadth of potential opportunistic pathogens. Individualized risk assessments, rapid and thorough diagnostic evaluation, and prompt initiation of appropriate antimicrobial therapies are essential. The approach to managing transplant recipients with infection in critical care is discussed and common and emerging opportunistic pathogens are reviewed.

Abstract
BACKGROUND Clostridium difficile infection (CDI) is a common cause of nosocomial antibiotic-associated diarrhea with an increased incidence reported in solid organ transplant recipients. We sought to determine if kidney and/or pancreas transplant recipients possess unique risk factors for CDI. METHODS Between January 2009 and February 2011, 942 kidney and 56 pancreas transplants were performed at the 2 centers. Of these, 28 recipients (kidney, n = 24; pancreas, n = 4) developed CDI. Cases were matched to controls (n = 56) in a 1:2 ratio. RESULTS Those with CDI were mostly male patients (82% vs. 48%, P = 0.003), deceased-donor organ recipients (86% vs. 64%, P = 0.045), more likely to have leukopenia (18% vs. 4%, P = 0.038), and had undergone a gastrointestinal procedure within 3 months preceding CDI diagnosis (18% vs. 4%, P = 0.038). Cases had higher cumulative and restricted antimicrobial exposure in days (37 ± 79 vs. 8 ± 12, P = 0.009 and 27 ± 69 vs. 7 ± 10, P = 0.032). Cephalosporin use was more common among cases (43% vs. 16%, P = 0.008). CONCLUSION Careful antimicrobial selection and assurance of optimal treatment duration in the kidney and pancreas transplant population is prudent. Clinicians should have a heightened awareness of CDI risk particularly during periods of leukopenia and in the setting of gastrointestinal procedures.

Abstract
Clostridium difficile-associated disease (CDAD) is the most common cause of nosocomial diarrhea. Information about CDAD in solid organ transplant (SOT) recipients is scarce. To determine its epidemiology and risk factors, we conducted a cohort study in which 4472 SOT patients were prospectively included in the RESITRA/REIPI (Spanish Research Network for the Study of Infection in Transplantation) database between July 2003 and July 2006. Forty-two episodes of CDAD were diagnosed in 36 patients. The overall incidence was 0.94%. Median onset of infection was 31.5 days (range 6-741); in half the cases, onset occurred during the first month after transplantation. In 26% of cases, there was no previous antibiotic use. Independent risk factors for CDAD using Cox regression analysis were previous use of first- and second-generation cephalosporins (HR 3.68; 95%CI 1.8-7.52; P < 0.001), ganciclovir prophylactic use (HR 3.09; 95%CI 1.44-6.62; P = 0.004) and corticosteroid use before transplantation (HR 2.95; 95%CI 1.1-7.9; P = 0.031). There were no deaths related to CDAD. In summary, the incidence of CDAD in SOT was low, most cases were diagnosed soon after transplantation and the prognosis was good.

Abstract
BACKGROUND Clostridium difficile-associated diarrhea (CDAD) is an increasingly important diagnosis in solid organ transplant recipients, with rising incidence and mortality. We describe the incidence, risk factors, and outcomes of colectomy for CDAD after solid organ transplantation. METHODS Patients with CDAD were identified from a prospective transplant database. Complicated Clostridium difficile colitis (CCDC) was defined as CDAD associated with graft loss, total colectomy, or death. RESULTS From 1999 to 2010, we performed solid organ transplants for 1331 recipients at our institution. The incidence of CDAD was 12.4% (165 patients); it increased from 4.5% (1999) to 21.1% (2005) and finally 9.5% (2010). The peak frequency of CDAD was between 6 and 10 days posttransplantation. Age more than 55 years (hazard ratio [HR]: 1.47, 95% confidence interval [CI]=1.16-1.81), induction with antithymocyte globulin (HR: 1.43, 95% CI=1.075-1.94), and transplant other than kidney alone (liver, heart, pancreas, or combined kidney organ) (HR: 1.41, 95% CI=1.05-1.92) were significant independent risk factors for CDAD. CCDC occurred in 15.8% of CDAD cases. Independent predictors of CCDC were white blood cell count more than 25,000/μL (HR: 1.08, 95% CI=1.025-1.15) and evidence of pancolitis on computed tomography scan (HR: 2.52, 95% CI=1.195-5.35). Six patients with CCDC underwent colectomy with 83% patient survival and 20% graft loss. Of the medically treated patients with CCDC (n=20), the patient survival was 35% with 100% graft loss. CONCLUSIONS We have identified significant risk factors for CDAD and predictors of progression to CCDC. Furthermore, we found that colectomy can be performed with excellent survival in selected patients.

Abstract
Severe disease caused by Clostridium difficile is frequently encountered in transplant recipients and carries a high mortality. Numerous studies have been published on this subject in the adult population, but few in the pediatric setting. A 4-year-old boy who had undergone heart transplant 20 months earlier was admitted to the pediatric intensive care unit after humoral rejection. Seven days after admission, he developed septic shock, abdominal distension, and paralytic ileus without diarrhea. Pseudomembranous colitis due to C. difficile was confirmed by microbiological and radiological studies. Despite treatment with rectal vancomycin and intravenous metronidazole, the patient did not improve and required decompressive laparotomy; because of the poor subsequent clinical course, terminal ileostomy and cecostomy were performed in a second operation. Recovery was satisfactory, and surgical reconstruction of intestinal tract was performed 3 months later without complications. Although early surgery with total colectomy is indicated, when there is a poor response to medical treatment in cases of C. difficile toxic megacolon, the case we present responded favorably to a conservative surgical approach that enabled intestinal integrity to be restored 3 months later. In the pediatric population, less aggressive therapeutic options should be considered, as they have benefits on the subsequent quality of life of the patient.
