Nonverbal Communication and Psychopathology in Kidney Transplant Recipients

Transplant recipients have difficulty expressing, identifying, and describing their emotional experiences. The Machover human figure test allows us to bring out the deepest contents of a patient's personality, which are normally hidden and not explained to structured quantitative tests. The study analyzed possible situations of distress and possible symptoms of psychopathology in kidney transplant recipients, emerged from the projective test of the human figure and not easily verbalized to the common standardized tests.The sample included 80 kidney transplant patients (51 men and 29 women; mean age, 47.74 [SD, 12.39] years) during follow-up visits at 12 months after transplant. The Machover test was used to evaluate body image, affective aspects, and personality variables by projective method; the Symptom Checklist-90-R was used for the evaluation of possible psychopathology, and the 36-Item Short Form Health Survey was used for the assessment of perceived quality of life.Resultsshowed that the more anxiety there is in the human figure test, the less somatization dimensions (ANX/SOM R = ?331, P < .05), depression (ANX/DEP R = ?326, P < .05), and the global index of psychic symptomatology (ANX/GSI R = ?367, P < .05) of the Symptom Checklist-90-R are present.This research has confirmed the hypothesis that the spontaneous graphic production of the recipients, through the projective methods, allows them to identify and deepen their psychological contents and to activate and maintain a good psychophysical balance post transplant.     

Associations Between Recipients’ Feelings of Guilt for Donor and Depressive Symptoms Before Living Kidney Transplantation

BackgroundRecipient depression before kidney transplantation needs to be treated to reduce poor posttransplant outcomes. For recipients who receive living kidney transplantation, feelings of guilt for potential donors may be factors related to the presence of depressive symptoms. This study aimed to examine the association between recipients’ feelings of guilt for the donor and depressive symptoms before living kidney transplantation.MethodsParticipants included 178 patients in Sapporo City General Hospital, Hokkaido, Japan, who completed a questionnaire before having living kidney transplantation from April 2009 to May 2016. Feelings of guilt for the donor, depressive symptoms using the Beck Depression Inventory-II (BDI-II), relationship to the donor, dialysis period, and socio-demographic characteristics were assessed via a questionnaire. Multivariate regression analyses were performed to examine the association between feelings of guilt for the donor and BDI-II score after multiple imputations.ResultsThe results showed that feelings of guilt for donors were associated with depressive symptoms, especially cognitive factors.ConclusionsThese findings indicate that medical staff needs to address recipients’ feelings of guilt for donors before living kidney transplantation.     

Analysis of Donor Factors for Non–Heart-Beating Donors With Regard to Cadaveric Kidney Transplantation in the Western Region of Japan

Background

Kidneys from non–heart-beating donors are thought to be marginal, and careful evaluation is required. Mass analyzed data are limited, and each transplant surgeon must evaluate these organs on the basis of their own experience.

Low Body Mass Index in Kidney Transplant Recipients: Risk or Advantage for Long-Term Graft Function?

OBJECTIVES: Nutritional status is known to be a marker of overall health status and a strong predictor of patient survival in several diseases. Whereas obesity is suspected to have a negative influence on general renal transplantation outcomes, the relationship between impaired nutritional status and long-term kidney graft survival is not yet clear. METHODS: We retrospectively analyzed graft survival with a follow-up time of 5 to 12.5 years among 224 kidney transplantations. A Cox proportional hazards model was applied to estimate risk factors for loss of graft function. RESULTS: The Cox model initially showed no significant influence of the body mass index (BMI) at 1 year after transplantation on the risk of transplant failure (relative risk 0.97 per BMI unit, P = .34). When the patients were divided into two groups according to BMI, a clear disadvantage was shown in terms of long-term graft survival for the groups with a low BMI. The risk of loss of transplant function increased by a factor of 1.85 (relative risk) if the BMI 1 year after kidney transplantation was less than 23 (P = .035). CONCLUSIONS: These findings suggested impaired long-term kidney graft survival among patients with reduced nutritional status. This result is assumed to reflect improved immune function due to reduced nutrient availability, thus leading to reinforcement of chronic rejection processes. This assumption is consistent with the already known immunomodulatory effect of caloric restriction to mitigate T-cell activation.     

NAFLD and Insulin Resistance Do Not Increase the Risk of Postoperative Complications Among Patients Undergoing Bariatric Surgery—A Prospective Analysis

Background  

Nonalcoholic fatty liver disease (NAFLD) and insulin resistance are common consequences of obesity and are highly prevalent among patients undergoing bariatric surgery. Insulin resistance and NAFLD have been reported to be associated with postoperative complications following major surgery.     

Outcomes of En Bloc Kidney Transplantation From Pediatric Donors: A Single-Center Experience

Background

To overcome a shortage of donors, cadaveric pediatric en bloc kidneys can be used to expand the donor pool. Recent evidence shows that en bloc kidney transplantation (EBKT) has better outcomes than standard-criteria deceased adult donor kidney transplantation. We reviewed our experiences of EBKT and their outcomes.

Does Expanded Criteria Donor Status Modify the Outcomes of Kidney Transplantation From Donors After Cardiac Death?

The outcomes of kidney transplants that simultaneously exhibit donation after cardiac death (DCD) and expanded criteria donor (ECD) characteristics have not been well studied. We examined the outcomes of DCD versus non‐DCD kidney transplants as a function of ECD status and the kidney donor risk index (KDRI). A cohort study of 67 816 deceased donor kidney transplant recipients (KTR), including 562 ECD/DCD KTR, from January 1, 2000 to December 31, 2009 was conducted using the Scientific Registry of Transplant Recipients. In a multivariable Cox proportional hazards model, the modestly increased risk of total graft failure in DCD versus non‐DCD KTR was not significantly modified by ECD status (hazard ratio1.07 [95% CI: 1.01, 1.15] for non‐ECD vs. 1.21 [95% CI: 1.04, 1.40] for ECD, p for interaction = 0.14).Moreover, the hazard ratios did not significantly vary by KDRI quintiles (p = 0.40). Similar trends were seen for death‐censored graft failure and death with graft function. In conclusion, ECD status or higher KDRI score did not appreciably increase the relative hazard of adverse graft and patient outcomes in DCD KTR. These findings suggest that the judicious use of ECD/DCD donor kidneys may be an appropriate strategy to expand the donor pool.     

Analysis of Specificity of Anti–Human Leukocyte Antigen Antibodies in Kidney Recipients in Reference to Clinical Outcome

Background

Anti–human leukocyte antigens antibodies (HLA) are not always the main cause of graft injury but can be a marker of immune response to the graft. The aim of this study was to analyze anti-HLA specificities with the use of the most sensitive detection method (Luminex) in reference to clinical condition.

Methods

Sera of 65 kidney recipients (n = 443) were screened with the use of the mixed LABScreen kit, and, for 47 recipients, sera with maximal normalized background ratio (NBG) were subjected to specificity testing. NBG, numbers of specificities, donor-specific antibodies (DSA), and normalized mean fluorescence index (nMFI) of DSA and maximal anti-HLA were analyzed in reference to clinical (acute rejection [AR] diagnosis, immunosuppression), histopathological (C4d staining, chronic allograft nephropathy, AR type), and laboratory parameters (creatinine).

Results

We observed 1 to 51 specificities, class I DSA in 26.7%, class II in 10%, and estimated DQ-DSA in 63.3% of tested patients. Patients with AR and humoral AR had significantly higher NBG, number of anti-HLA class I, DQ and DQ-DSA types, and more frequently had anti-HLA and class II DSA-positive sera (P < .052). C4d staining was associated with higher anti-HLA class I (P = .053) and class I DSA (P = .002) type numbers, and maximal anti-HLA nMFI (P = .036) and was more frequent in AR (P = .048) and class II DSA positive patients (P = .046). Patients with chronic allograft nephropathy showed higher DQ-DSA-nMFI (P = .036). DQ-DSA-nMFI and maximal anti-HLA-nMFI correlated with creatinine increase (Spearman range [SR] = 0.64, SR = 0.41). Together with NBG, maximal class I and class II anti-HLA-nMFI correlated with the number of transplantation and maximal panel-reactive antibodies ratio (SR = 0.19–0.40).

Conclusions

Anti-HLA detection allows for humoral AR diagnosis but also for identification of patients with risk of any rejection. However, clear rules of anti-HLA interpretation and studies on their clinical impact are needed.     

Living Kidney Donation From a Donor With Pulmonary Sarcoidosis: A Case Report and Review of the Literature

Background

Sarcoidosis is a chronic systemic disease that is characterized by the formation of noncaseating granuloma and whose etiology is unclear. It is unclear whether patients with sarcoidosis are suitable organ donors.

Treatment of Anemia With Erythropoietin-Stimulating Agents in Kidney Transplant Recipients and Chronic Kidney Disease—Another Drawback of Immunosuppression?

Anemia is more prevalent in allograft recipients compared with glomerular filtration rate (GFR) matched patients with chronic kidney diseases. There is a paucity of data concerning the correction of anemia in the posttransplant period with erythropoietin-stimulating agents (ESA). The aim of this study was to compare the iron status, kidney function, inflammatory state, use of drugs affecting erythropoiesis (immunosuppressants ACEi/ARB) and correction of anemia using ESA in a chronic kidney disease (CKD) population versus kidney transplant recipients. We included 67 patients treated with ESA including 17 after kidney transplantation. CKD Patients with native kidneys were significantly older than allograft recipients (mean age 69 versus 51 years; P < .001, and despite similar serum creatinine and iron parameters showed an estimated lower GFR (19 mL/min versus 23 mL/min; P < .05). Median time of ESA therapy was similar among patients with native kidney CKD versus kidney recipients, but they achieved a significantly higher hemoglobin (11.04 versus 10.36 g/dL; P < .05). There was no difference between patients administered or not a mammalian target of rapamycin antagonist. None of the patients with native kidney CKD received immunosuppressive therapy, but they were prescribed ACEi more often than kidney recipients. The higher degree of anemia in kidney allograft recipient is the most probably attributed to the use of immunosuppressive drugs, despite their better kidney function and comparable iron status. This study suggested that higher doses of ESA should be employed to anemia in kidney transplant recipients.     

Critical Analysis of Strattice Performance in Complex Abdominal Wall Reconstruction: Intermediate–Risk Patients and Early Complications

The purpose of this study was to analyze the performance of a porcine-derived acellular dermal matrix (Strattice Reconstructive Tissue Matrix) in patients at increased risk for perioperative complications. We reviewed medical records for patients with complex abdominal wall reconstruction (AWR) and Strattice underlay from 2007 to 2010. Intermediate-risk patients were defined as having multiple comorbidities without abdominal infection. Forty-one patients met the inclusion criteria (mean age, 60 years; mean body mass index, 35.5 kg/m²). Comorbidities included coronary artery disease (63.4%), diabetes mellitus (36.6%), and chronic obstructive pulmonary disease (17.1%). Fascial closure was achieved in 40 patients (97.6%). Average hospitalization was 6.4 days (range, 1–24 days). Complications included seroma (7.3%), wound dehiscence with Strattice exposure (4.9%), cellulitis (2.4%), and hematoma (2.4%). All patients achieved abdominal wall closure with no recurrent hernias or need for Strattice removal. Patients with multiple comorbidities at intermediate risk of postoperative complications can achieve successful, safe AWR with Strattice.     

Impact of Urinary Tract Infections in Kidney Transplant Recipients: A 4-Year Single-Center Experience

Background

Urinary tract infection (UTI) is the most frequent bacterial infection in kidney transplant recipients (KTRs), yet little is known about the impact of severe UTIs. We aimed to explore the burden of severe UTIs post renal transplant on both graft function and health care resources.

A Cost-Effectiveness Analysis of Organ Preservation Methods for Deceased Donor Kidneys at High Risk for Delayed Graft Function in Brazil

The clinical benefit of machine perfusion (MP) was recently assessed in a 1-year Brazilian multicenter prospective randomized trial, that showed that the use of MP was associated with a reduced incidence of delayed graft function (DGF) compared to static cold storage (SCS) in kidney transplant recipients (45% vs 61%). The objective of the present analysis is to consider the cost-effectiveness of MP relative to SCS based on clinical data from this Brazilian cohort. A decision tree model was constructed to simulate a population of 1000 kidney transplant recipients based on data derived from this Brazilian multicenter clinical trial. The model accounts for different health state utilities to estimate the cost-effectiveness of deceased donor kidney transplantation in Brazil comparing 2 kidney preservation methods: MP and SCS. The model accounts for 3 possible graft outcomes at 1 year post-transplantation: success (an immediate functioning kidney), failure (primary nonfunction requiring a return to dialysis), or DGF 1 year post-transplant. MP provided 612 total quality-adjusted life years (QALYs) (0.61 QALYs per patient) as compared to SCS (553 total QALYs, 0.55 QALYs per patient). MP was cost effective relative to SCS (US$22,117/QALY, R$70,606/QALY). The use of MP also resulted in more functioning grafts than SCS (821 vs 787), leading to a cost per functioning graft of US$38,033 (R$121,417). In conclusion, this analysis indicates that, despite the initial added cost associated with MP, the use of MP results in more functioning grafts (821 vs 787) and higher patient quality of life relative to SCS in Brazil.     

Editorial Commentary: Complications and Readmission After Elective Arthroscopy—Is Body Mass Index a Trustworthy Measure of Risk?

A multivariate analysis of the American College of Surgeons National Surgical Quality Improvement Program database indicates that body mass index is not predictive of complications after elective arthroscopy; however, further analysis reveals underweight and obese patients may be at risk of 30-day morbidity or readmission after shoulder arthroscopy. These findings are consistent with previous reports yet conflict with others, raising concern over the utility of body mass index as a measure of the risk of morbidity and readmission after elective arthroscopy.
