Hypoalbuminemia is a risk factor for invasive fungal infections and poor outcomes in infected kidney transplant recipients. Clin Transplant 2023; 37:e15052. [PMID: 37329297 DOI: 10.1111/ctr.15052] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 05/13/2023] [Accepted: 06/08/2023] [Indexed: 06/19/2023]
Abstract
INTRODUCTION Invasive fungal infections (IFI), are estimated to occur in 2%-14% of kidney transplant recipients (KTRs) in the current era of immune suppression and are associated with high mortality rates. We hypothesized that hypoalbuminemia in KTRs is a risk factor for IFI and would be associated with poor outcomes. METHODS In this study, using data from a prospective cohort registry, we describe the frequency of IFI due to Blastomycosis, Coccidioidomycosis, Histoplasmosis, Aspergillosis, and Cryptococcus in KTRs with serum albumin levels measured 3-6 months before diagnosis. Controls were selected based on incidence density sampling. KTRs were divided into three groups based on the pre-IFI serum albumin level: normal (≥4 g/dL), mild (3-4 g/dL), or severe (<3 g/dL) hypoalbuminemia. Outcomes of interest were uncensored graft failure after IFI and overall mortality. RESULTS A total of 113 KTRs with IFI were compared with 348 controls. The incidence rate of IFI among individuals with normal, mild, and severe hypoalbuminemia was 3.6, 8.7, and 29.3 per 100 person-years, respectively. After adjustment for multiple variables, the trend for risk of uncensored graft failure following IFI was greater in KTRS with mild (HR = 2.1; 95% CI, .75-6.1) and severe (HR = 4.47; 95% CI, 1.56-12.8) hypoalbuminemia (P-trend < .001) compared to those with normal serum albumin. Similarly, mortality was higher in severe hypoalbuminemia (HR = 1.9; 95% CI, .67-5.6) compared to normal serum albumin (P-trend < .001). CONCLUSION Hypoalbuminemia precedes the diagnosis of IFI in KTRs, and is associated with poor outcomes following IFI. Hypoalbuminemia may be a useful predictor of IFI in KTRs and could be incorporated into screening algorithms.

Mizerska A, Durlik M, Kędzierska-Kapuza K. Nutritional Risk of Candidates for Simultaneous Pancreatic-Kidney Transplantation-A Narrative Review. Nutrients 2023; 15:4179. [PMID: 37836461 PMCID: PMC10574362 DOI: 10.3390/nu15194179] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/04/2023] [Revised: 09/14/2023] [Accepted: 09/21/2023] [Indexed: 10/15/2023] Open
Abstract
INTRODUCTION Not much is known about the significance of nutritional status and support in transplant surgery, least of all in simultaneous pancreatic and kidney transplantation. Malnutrition in the context of simultaneous pancreatic-kidney transplantation seems to be complex and a still poorly investigated problem. Since SPKTX is highly qualified and also has a small volume procedure, it is difficult to obtain data from large cohorts of patients. The aim of this article is to gather existing evidence and information about the subject, as well as to elicit some questions and goals for the future. METHODS We searched through the Pub-Med database using the keywords "pancreas and kidney transplantation" combined with "nutritional risk", "nutritional status", "malnutrition", "nutritional intervention", and "frailty", finding a total of 4103 matching results. We then narrowed it down to articles written in English with the full text available. We also researched through the references of articles most accurately matching our researched terms. RESULTS There are numerous tools that have been investigated for the screening of malnutrition, such as the NRI index, PNI index, NLR, SGA scale, and NRS-2002 scale, each of which proved to be of some use in predicting patient outcomes in different surgical settings. Since all of them differed in components and assessed parameters and, in the absence of more sensitive or infallible indicators, the most reasonable approach seems to evaluate them jointly. CONCLUSION It is important to underline the necessity of nutritional screening and the subsequent introduction of adequate therapy while awaiting transplantation in an attempt to improve results. Considering the complexity of surgical procedures and the severity of underlying diseases with their intense metabolic components, the patient's nutritional status seems to significantly influence results. Consequently, nutritional risk assessments should be a part of the routine care of patients qualified for transplantation.

Retrospective Analysis of the Risk Factors of Perioperative Bacterial Infection and Correlation with Clinical Prognosis in Kidney Transplant Recipients. Infect Drug Resist 2022; 15:2271-2286. [PMID: 35510155 PMCID: PMC9059986 DOI: 10.2147/idr.s356543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2022] [Accepted: 04/15/2022] [Indexed: 12/02/2022] Open
Abstract
Background Infection remains a leading cause of morbidity and mortality in kidney transplant patients. This study aimed to investigate the risk factors of bacterial infection during the perioperative period of transplantation and the effects of infection on long-term clinical outcomes. Methods In total, 295 kidney transplantation recipients were included in this retrospective study and assigned to two groups: non-infected and infected. The tacrolimus concentration, pharmacogenomics, laboratory parameters, and clinical outcomes of both groups were evaluated. Results A relatively low incidence of urinary tract infection was observed in our cohort, and lung was identified as the most frequent site of infection. Gram-negative bacteria, such as Escherichia coli, Pseudomonas aeruginosa, and Klebsiella pneumoniae, were the most common infecting strains in kidney transplant recipients. Patients with diabetes showed greater susceptibility to infection. Compared with the non-infected group, tacrolimus concentration was significantly lower on day 7 and 14 in the infected group. White blood cell count, neutrophil count, and C-reactive protein (CRP) in the infected group were markedly higher post-transplantation, while albumin levels were lower relative to the non-infected group. ABCB1 (rs2032582) genotype showed clear associations with infection. Furthermore, the incidence of delayed graft function (DGF) and early acute rejection (AR) before infection was significantly greater in the infected group. Finally, early post-transplant infection was associated with a marked increase in the incidence of AR, post-transplant diabetes mellitus (PTDM), and secondary infection. Conclusion Pre-diabetes, longer duration of catheterization, lower albumin, higher CRP, tacrolimus concentration on the day 7 and 14, early AR before infection, and DGF were closely related to postoperative infection in kidney transplantation recipients. Moreover, bacterial infection during the perioperative period was closely associated with AR, PTDM and secondary infection.

Abstract
Objective: To determine the effect of the serum albumin level on admission in patients with spontaneous subarachnoid hemorrhage (SAH). Methods: A total of 229 patients with SAH were divided into control and hypoalbuminemia groups. The serum albumin levels were measured. The data, including age, gender, co-existing medical conditions, risk factors, Hunt-Hess (H-H) grade on admission, Glasgow coma score (GCS) on admission, complications during hospitalizations, length of hospital stay, length of intensive care unit (ICU) stay, in-hospital mortality, survival rate, outcome at discharge, and the 6-month follow-up outcome, were compared between the two groups. Results: Older age, an increased number of patients who consumed an excess of alcohol, and a lower GCS on admission were findings in the hypoalbuminemia group compared to the control group (p < 0.001). The ratio of patients with H-H grade I on admission in the hypoalbuminemia group was decreased compared to the control group (p < 0.05). Patients with hypoalbuminemia were more likely to be intubated, and have pneumonia and cerebral vasospasm than patients with a normal albumin level on admission (p < 0.001). Furthermore, the length of hospital and ICU stays were longer in the hypoalbuminemia group than the control group (p < 0.001). Hypoalbuminemia on admission significantly increased poor outcomes at discharge (p < 0.001). The number of patients with severe disability was increased and the recovery rate was decreased with respect to in-hospital outcomes in the hypoalbuminemia group than the control group (p < 0.001). Conclusion: Hypoalbuminemia was shown to be associated with a poor prognosis in patients with SAH.

Abstract
Enhanced recovery after surgery (ERAS) initially started in the early 2000s as a series of protocols to improve the perioperative care of surgical patients. They aimed to increase patient satisfaction while reducing postoperative complications and postoperative length of stay. Despite these protocols being widely adopted in many fields of surgery, they are yet to be adopted in pancreatic transplantation: a high-risk surgery with often prolonged length of postoperative stay and high rate of complications. We have analysed the literature in pancreatic and transplantation surgery to identify the necessary preoperative, intra-operative and postoperative components of an ERAS pathway in pancreas transplantation.

Kidney Int Rep 2020; 5:2228-2237. [PMID: 33305116 PMCID: PMC7710825 DOI: 10.1016/j.ekir.2020.09.012] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 09/04/2020] [Accepted: 09/08/2020] [Indexed: 12/20/2022] Open
Abstract
Introduction Opportunistic viral infections cause extensive morbidity and mortality in kidney transplant recipients (KTRs). Low serum albumin levels before and after transplant have been associated with negative outcomes. However, it is uncertain whether serum albumin levels before transplantation are associated with the risk for post-transplantation opportunistic BK polyomavirus (BKV) or cytomegalovirus (CMV). Methods We reviewed all KTRs transplanted at our institution between 1 January 2005 and 31 December 2015 with serum albumin measured within 45 days before transplantation in a retrospective observational cohort study. Selected patients were stratified into 3 groups: normal albuminemia (≥3.5 g/dl), moderate hypoalbuminemia (3.49–2.5 g/dl), and severe hypoalbuminemia (<2.5 g/dl). Patients were observed for post-transplantation BKV or CMV according to standard of care. Results We included 1717 patients in this study; 72.3% had normal serum albumin, 26.3% had moderate hypoalbuminemia, and 1.5% had severe hypoalbuminemia. Moderate and severe hypoalbuminemia incurred a higher risk for BKV compared with normal serum albumin levels in univariable analysis (moderate hypoalbuminemia: hazard ratio [HR] = 1.5; 95% confidence interval [CI], 1.14–1.90; P = .003); severe hypoalbuminemia: HR = 2.15; 95% CI, 1.01–4.56; P = 0.05). Although not significant after multivariable adjustment, there was still 18% increased risk in moderate hypoalbuminemia and 64% in severe hypoalbuminemia for BKV compared with the normal albumin group. Moderate hypoalbuminemia was associated with a higher risk for CMV infection than normal serum albumin levels in multivariable analysis, although it was not statistically significant (HR = 1.15; 95% CI, 0.36–3.64; P = 0.81). Conclusions These findings suggest that pretransplantation hypoalbuminemia is associated with a higher risk for post-transplantation BKV and possibly CMV. More intense screening is warranted for these viruses in recipients with pretransplant hypoalbuminemia.

Abstract
Introduction: There is a high incidence of venous thromboembolism (VTE) in solid organ transplant recipients. The safety and efficacy of direct-acting oral anticoagulants (DOAC) have been well established in clinical practice for the prevention and treatment of VTE in broad populations. However, the management of VTE in the setting of solid organ transplantation remains a challenge to clinicians due to limited evidence of DOAC usage with calcineurin inhibitors. Areas covered: The current literature available on the pharmacokinetic-pharmacodynamic interaction between DOACs and calcineurin inhibitors is presented. A comprehensive review was undertaken using PubMed, Embase, drug product labeling, and drug product review conducted by the US Food and Drug Administration using Drugs@FDA. The potential for mitigation strategies and clinical management using extant knowledge is explored. Expert opinion: Immunosuppression therapy is necessary to prevent graft rejection by the host. The sparsity of data together with the lack of well-designed prospective studies of DOAC use in solid organ transplant recipients presents a unique challenge to clinicians in determining the clinical relevance of possible drug interactions. Existing evidence suggests that with attention to concomitant drug use and renal function, the co-administration of DOACs and calcineurin inhibitors is safe and effective.

Clin Nutr ESPEN 2016; 17:22-27. [PMID: 28361743 DOI: 10.1016/j.clnesp.2016.12.002] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/20/2016] [Revised: 09/09/2016] [Accepted: 12/04/2016] [Indexed: 11/17/2022]
Abstract
BACKGROUND Early post-operative enteral nutrition is an important part of perioperative management and is strongly supported by ESPEN Guidelines. However, there is limited evidence into the use of Early Enteral Nutrition (EEN) after combined Pancreas and Kidney Transplantation (PKT). We know malnutrition in type-1 diabetics with end stage renal failure (ESRF) is a common problem and a significant risk factor. Therefore, we introduced EEN in our patients. METHOD We monitored and recorded nutritional data on 29 PKT recipients who underwent transplantation between Oct 2007 and Jan 2010 without a nutritional assessment or EEN [Monitored Group (MG)] and on 30 PKT recipients between Feb 2010 and Dec 2013 who received a nutritional assessment and EEN (Naso-jejunal feed or oral intake with supplementation, according to their nutritional status) [Fed Group (FG)]. The end-point was to assess patients' daily post-transplant nutritional intake. This was calculated as a percentage of estimated nutritional requirements using the Schofield equation with a 25% added stress factor and relevant activity factor. Following a literature search and realistic targets our aim was to reach >60% requirements: achievement of ≥60% energy requirements by day-7 (7d-60%) and at the time of discharge (total-60%) [13,14]. RESULTS There was no significant difference between MG and FG patients in cold ischemic time (CIT), recipient-age and donor-age, Length of Stay and donor-creatinine. In contrast, FG patients were less frequently in predialysis status 41.4% vs. 26.7%, p = 0.001; and had higher incidence of BMI <22.5 kg/m2 63.3% vs. 48.3%, p = <0.005. In outcomes, FG patients more frequently achieved a higher average % of nutritional requirements in the first week 39.69% vs. 22.37%, p = <0.005; as well as during whole in-patient stay 57.24% vs. 44.43%, p = <0.005 (Table 3, Figs. 1 and 2). The FG spent a greater proportion during the first week 66.7% vs. 31%, p = <0.005; and of whole their admission 93.3% vs. 75.9%, p = <0.005; meeting more than 60% of nutritional requirements. Most important, the need for parenteral nutrition within the FG was significantly lower, 7.1% vs. 20.7%, p < 0.005 (Table 3). CONCLUSION Our results show that these patients benefit from planned EEN and receive better nutritional support when compared to the patients managed with the historic, reactive approach to nutritional care. Nutritional intake in the first week as well as during the whole admission was superior in patients receiving active EEN despite a more difficult post-operative course due to higher incidence of re-operations compared to the control group. Also the need for parenteral nutrition was significantly lower in this group. In addition, pre-transplant nutritional assessment is beneficial and accurately highlights those who may be at risk of malnutrition pre and post-operatively.

Abstract
Low serum albumin levels have been reported to be an independent predictor of increased morbidity and mortality in multiple disease conditions. The aim of our study was to identify the impact of low serum albumin levels on mortality and outcomes at discharge in patients with intracerebral hemorrhage. We retrospectively reviewed our prospective database of patients with intracerebral hemorrhage from January 2010 to December 2011. Patients were dichotomized into two groups based on their serum albumin levels upon admission. Hypoalbuminemia was defined as serum albumin levels ≤3.4 g/dl. The two groups were compared using Fisher's exact test for categorical variables and t test for continuous variables. Poor outcome was defined as death or discharge to a long-term nursing facility (modified Rankin Score 4-6). Out of 97 patients admitted with intracerebral hemorrhage, 90 met our inclusion criteria (42 had normal levels and 48 had hypoalbuminemia). The baseline characteristics, risk factors, etiology, location and volume of intracerebral hemorrhage, admission blood glucose, white cell count, length of hospital stay, length of intensive care unit stay, and complications were similar between both groups. Although admission hypoalbuminemia did not impact in-hospital mortality (28 vs 24 %, p = 0.635), there was a significant increase in poor outcomes at discharge (59 vs 31 %, p = 0.009) (OR 1.8; 95 % CI; 1.2-2.8). Similar to other diseases, hypoalbuminemia was associated with poor functional outcomes in patients with intracerebral hemorrhage. This will need to be confirmed in larger prospective studies before adopting therapeutic and preventive strategies in future.

Abstract
Screening renal biopsies (RB) may assess early changes of interstitial fibrosis (IF) after transplantation. The aim of this study was to quantify IF by automatic color image analysis on sequential RB. We analyzed RB performed at day (D) 0, month (M) 3 and M12 from 140 renal transplant recipients with a program of color segmentation imaging. The mean IF score was 19 ± 9% at D0, 27 ± 11% at M3 and 32 ± 11% at M12 with a 8% progression during the first 3 months and 5% between M3 and M12. IF at M3 was correlated with estimated glomerular rate (eGFR) at M3, 12 and 24 (p < 0.02) and IF at M12 with eGFR at M12 and 48 (p < 0.05). Furthermore, IF evolution between D0 and M3 (ΔIFM3-D0) was correlated with eGFR at M24, 36 and 48 (p < 0.03). IF at M12 was significantly associated with male donor gender and tacrolimus dose (p = 0.03). ΔIFM3-D0 was significantly associated with male donor gender, acute rejection episodes (p = 0.04) and diabetes mellitus (p = 0.02). Thus, significant IF is already present before transplantation. IF evolution is more important during the first 3 months and has some predictive ability for change in GFR. Intervention to decrease IF should be applied early, i.e. before 3 months, after transplantation.

Abstract
OBJECTIVE This research study was conducted to investigate whether serum albumin levels predict allograft/patient outcomes in the new era of transplant medicine and immunology. METHODS The association of 1-year post-transplant serum albumin, and patient and graft outcomes was retrospectively analyzed in 500 kidney transplant recipients between 1998 and 2005. Albumin was used as a categorical and a continuous variable in univariate and multivariate Cox regression and Kaplan-Meier survival analyses. RESULTS The average (±SE) age at transplant was 47 ± 12 years. Patients were followed up for 63.4 ± 28 months after transplant. There were 56 graft losses and 38 patient deaths. In univariate analysis, the following variables were associated with the composite endpoint of patient death or allograft loss: 1-year serum albumin (hazard ratio [HR] = 0.52, P = .0009), 1-year serum albumin <4.0 g/dL (HR = 1.81, P = .02), 1-year serum creatinine (HR = 3.55, P < .00001), angiotensin converting enzyme inhibitors or angiotensin receptor blockers use (HR = 1.61, P = .03), a history of previous transplant (HR = 1.54, P = .04), months of dialysis before transplant (HR = 1.01, P = .00003), type of transplant (deceased donor HR = 1.64, P = .02), and acute rejection (HR = 1.52, P = .0000003). Of these, multivariable Cox regression analyses retained 1-year serum albumin (HR = 1.4, P < .0001), serum creatinine (HR = 2.7, P < .0001), and acute rejection (HR = 1.7, P = .02) as significant predictors of patient/graft loss. CONCLUSION One-year serum albumin is an independent predictor of poor outcomes in the contemporary era of transplant medicine and immunosuppression. Further studies are needed to separate the role of this biomarker in inflammation and nutrition in kidney transplant recipients.

Abstract
BACKGROUND To examine the relationship between admission serum albumin and 30-day mortality during an emergency medical admission. METHODS An analysis was performed of all emergency medical patients admitted to St. James's Hospital (SJH), Dublin between 1st January 2002 and 31st December 2008, using the hospital in-patient enquiry (HIPE) system, linked to the patient administration system, and laboratory datasets. Mortality was defined as an in-hospital death within 30 days. Logistic regression was used to calculate unadjusted and adjusted odds ratios (ORs) and 95% confidence intervals for defined albumin subsets. FINDINGS Univariate analysis using predefined criteria based on distribution, identified the groups of <10% and between 10 and 25% of the serum albumin frequency distribution as at increased mortality risk. Their mortality rates were 31.7% and 15.4% respectively; their unadjusted odds rates were 6.35 (5.68, 7.09) and 2.11 (1.90, 2.34). Patients in the lowest 25% of the distribution had a 30-day mortality of 19.9% and this significantly increased risk persisted, after adjustment for other outcome predictors including co-morbidity and illness severity (OR 2.95 (2.49, 3.48): p<0.0001). INTERPRETATION Serum albumin is predictive of 30-day mortality in emergency medical patients; mortality is non-linearly related to baseline albumin. The disproportionate increased death risk for patients in the lowest 25% of the frequency distribution (<36 g/L) is not due to co-morbidity factors or acute illness severity.

Abstract
BACKGROUND Renal interstitial fibrosis (IF) is the main histopathological feature of chronic allograft injury. IF is currently assessed by semiquantitative analysis, but automatic color image analysis may be more reliable and reproducible. We performed a retrospective analysis to calculate IF on routine renal biopsies performed at 1 year posttransplant. METHODS Data were obtained from MO2ART, a prospective multicenter trial in which cyclosporine A dose was adjusted based on C2 level. One-year routine biopsies were assessed from 26 patients from two centers. For each biopsy, a section was analyzed by a program of color segmentation imaging, which automatically extracts green color areas characteristic of IF. Results were expressed as percentage of IF and grade (grade 1: <25%, grade 2: 25-50%, and grade 3: >50%). RESULTS Mean IF score was 0.35+/-0.04. Quantitative IF grade 1 was observed in 9 biopsies (34.6%), grade 2 in 12 (46.1%), and grade 3 in 5 (19.2%). Diabetes and cytomegalovirus infection were significantly associated with a higher percentage of IF. There was no correlation between the group of randomization and IF. We found a statistical significant correlation between Banff 05 chronic lesions classification and the IF index (P<0.02). Repeated analysis of variance demonstrated an association between high grade of automated IF and a worsening of creatinine clearance (Modification of Diet in Renal Disease) between 1 and 3 years. CONCLUSIONS Automatic quantification of IF on routine renal biopsies at one year posttransplant is predictive of long-term allograft function and may assist early diagnosis of the interstitial lesions of chronic allograft injury.

Abstract
OBJETIVO: Avaliar o efeito provocado pelo trauma cirúrgico na concentração de albumina sérica no pós-operatório imediato. MÉTODO: Foram estudados aleatoriamente 200 pacientes adultos, submetidos a cirurgias eletivas de e grande porte (Grupo 1) e médio porte (Grupo 2), identificados de acordo com o sexo, a idade e a cor da pele. As amostras sangüíneas para dosagem da concentração sérica de albumina foram obtidas nos dias anterior e posterior ao procedimento cirúrgico. RESULTADOS: Houve diminuição da albumina sérica tanto no Grupo 1 (p<0,0001) quanto Grupo 2 (p<0,0001). Não houve diferença entre os sexos e cores da pele dos pacientes nas cirurgias de grande porte. Entretanto, as mulheres apresentaram menor redução da albumina sérica nas operações de médio porte do que os homens. Ainda em relação às cirurgias de médio porte, a albumina diminuiu menos nos melanodérmicos em relação aos feodérmicos e nestes menos do que nos leucodérmicos. Em relação às faixas etárias, em ambos os grupos, houve maior redução da albumina nos pacientes acima de 65 anos, seguidos pelos mais jovens (<45 anos) e, por último, entre 45 e 65 anos. CONCLUSÕES: As operações de médio e grande porte provocam redução imediata da albuminemia, com maior intensidade em homens, idosos e leucodérmicos.

Abstract
OBJECTIVE To determine whether hypoalbuminemia is an independent risk factor for poor outcome in the acutely ill, and to assess the potential of exogenous albumin administration for improving outcomes in hypoalbuminemic patients. SUMMARY BACKGROUND DATA Hypoalbuminemia is associated with poor outcomes in acutely ill patients, but whether this association is causal has remained unclear. Trials investigating albumin therapy to correct hypoalbuminemia have proven inconclusive. METHODS A meta-analysis was conducted of 90 cohort studies with 291,433 total patients evaluating hypoalbuminemia as an outcome predictor by multivariate analysis and, separately, of nine prospective controlled trials with 535 total patients on correcting hypoalbuminemia. RESULTS Hypoalbuminemia was a potent, dose-dependent independent predictor of poor outcome. Each 10-g/L decline in serum albumin concentration significantly raised the odds of mortality by 137%, morbidity by 89%, prolonged intensive care unit and hospital stay respectively by 28% and 71%, and increased resource utilization by 66%. The association between hypoalbuminemia and poor outcome appeared to be independent of both nutritional status and inflammation. Analysis of dose-dependency in controlled trials of albumin therapy suggested that complication rates may be reduced when the serum albumin level attained during albumin administration exceeds 30 g/L. CONCLUSIONS Hypoalbuminemia is strongly associated with poor clinical outcomes. Further well-designed trials are needed to characterize the effects of albumin therapy in hypoalbuminemic patients. In the interim, there is no compelling basis to withhold albumin therapy if it is judged clinically appropriate.

Abstract
BACKGROUND Infections following solid-organ transplants are a major cause of morbidity and mortality. Few studies have reported the complications of hepatic abscesses. METHODS This investigation consisted of a retrospective chart review of all solid-organ transplant recipients from 1990 to 2000. Criteria for diagnosis included parenchymal hepatic lesions, positive cultures from liver aspirates or blood cultures, or both, and a compatible clinical presentation. RESULTS Of 2,175 recipients of all organ transplants (heart, lung, kidney, liver, pancreas), we identified 12 patients who had experienced 14 episodes of hepatic abscess, all in liver transplant recipients. Median time from transplant to hepatic abscess was 386 days (range 25-4,198). The most common predisposing factor was hepatic artery thrombosis (HAT), which occurred in eight patients, and was diagnosed at an average of 249 days (range 33-3,215) after transplantation. Clinical presentation of hepatic abscess was similar to that described in non-immunosuppressed patients. All but one patient showed hypoalbuminemia (<3.5 g/dL); those with HAT also had significantly elevated lactate dehydrogenase. Liver aspirates grew gram-positive aerobic bacteria (50% of isolates), gram-negative aerobic bacteria (30%), and anaerobes and yeasts (10% each). Patients received an average of 6 weeks of intravenous antibiotic therapy. Catheter drainage was successful in 70% of cases; and five patients required retransplantation. Altogether, five of the patients died, yielding a mortality rate of 42%. CONCLUSIONS Hepatic abscess, a rare complication after liver transplantation, was frequently associated with hepatic artery thrombosis. Mortality was higher than in patients who had not undergone transplantation. Prolonged antibiotic therapy, drainage, and even retransplantation may be required to improve the outcome in these patients.

Abstract
Infectious complications are still a significant cause of morbidity and death in solid-organ transplant patients, with significant infection being found in up to two-thirds of these individuals. The risk of infection in the organ transplant patient, particularly of opportunistic infection, is largely determined by 3 factors: the net state of immunosuppression, the epidemiologic exposures the patient encounters, and the consequences of the invasive procedures to which the patient is subjected. The most important principles of patient treatment are prevention, early diagnosis, and specific therapy. This issue is designed as a position paper by a group of experts on epidemiology, prevention, diagnosis, and management of infections in solid-organ transplant patients. We feel that our efforts may serve as an important first step in the development of guidelines in this area.

Abstract
Timely nutrition assessment and intervention in organ transplant recipients may improve outcomes surrounding transplantation. A pretransplant nutrition assessment should include a variety of parameters including physical assessment, history, anthropometric measurements, and laboratory tests. Malnutrition compromises posttransplant survival; prolonged waiting times worsen outcomes when patients are already malnourished. Severe obesity may decrease graft function and survival in kidney transplant recipients. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by organ failure. Enteral tube feeding is indicated for patients with functional gastrointestinal tracts who are not eating adequately. Parenteral nutrition is rarely needed pretransplant except in cases of intestinal failure. When determining pretransplant nutrient requirements, nutritional status, weight, age, gender, metabolic state, stage and type of organ failure, malabsorption, induced losses, goals, and comorbid conditions must be considered. During the acute posttransplant phase, adequate nutrition is required to help prevent infection, promote wound healing, support metabolic demands, replenish lost stores, and perhaps mediate the immune response. Nutrient recommendations reflect posttransplant metabolic changes. The appropriateness of posttransplant nutrition support depends on the prevalence of malnutrition among patients with a specific type of organ failure and the benefits when nutrition support is given. Organ transplantation complications including rejection, infection, wound healing, renal insufficiency, hyperglycemia, and surgical complications require specific nutritional requirements and therapies. Many potential applications of nutrition in the pre- and posttransplant phases exist and require further study.

Abstract
Many complications after renal transplantation can be prevented if they are detected early. Guidelines have been developed for the prevention of diseases in the general population, but there are no comprehensive guidelines for the prevention of diseases and complications after renal transplantation. Therefore, the Clinical Practice Guidelines Committee of the American Society of Transplantation developed these guidelines to help physicians and other health care workers provide optimal care for renal transplant recipients. The guidelines are also intended to indirectly help patients receive the access to care that they need to ensure long-term allograft survival, by attempting to systematically define what that care encompasses. The guidelines are applicable to all adult and pediatric renal transplant recipients, and they cover the outpatient screening for and prevention of diseases and complications that commonly occur after renal transplantation. They do not cover the diagnosis and treatment of diseases and complications after they become manifest, and they do not cover the pretransplant evaluation of renal transplant candidates. The guidelines are comprehensive, but they do not pretend to cover every aspect of care. As much as possible, the guidelines are evidence-based, and each recommendation has been given a subjective grade to indicate the strength of evidence that supports the recommendation. It is hoped that these guidelines will provide a framework for additional discussion and research that will improve the care of renal transplant recipients.
