Frequency of and reasons behind non-listing in adult patients referred for liver transplantation: Results from a retrospective study.

BACKGROUND: Few studies have evaluated the frequency of and the reasons behind the refusal of listing liver transplantation candidates. AIM: To assess the ineligibility rate for liver transplantation and its motivations. METHODS: A single-center retrospective study was conducted on adult patients which entailed a formal multidisciplinary assessment for liver transplantation eligibility. The predictors for listing were evaluated using multivariable logistic regression. RESULTS: In our center, 314 patients underwent multidisciplinary work-up before liver transplantation enlisting over a three-year period. The most frequent reasons for transplant evaluation were decompensated cirrhosis (51.6%) and hepatocellular carcinoma (35.7%). The non-listing rate was 53.8% and the transplant rate was 34.4% for the whole cohort. Two hundred and five motivations for ineligibility were collected. The most common contraindications were psychological (9.3%), cardiovascular (6.8%), and surgical (5.9%). Inappropriate or premature referral accounted for 76 (37.1%) cases. On multivariable analysis, a referral from another hospital (OR: 2.113; 95%CI: 1.259-3.548) served as an independent predictor of non-listing. CONCLUSION: A non-listing decision occurred in half of our cohort and was based on an inappropriate or premature referral in one case out of three. The referral from another hospital was taken as a strong predictor of non-listing.

Gut Microbiota Signatures Are Associated With Psychopathological Profiles in Patients With Ulcerative Colitis: Results From an Italian Tertiary IBD Center.

BACKGROUND: Several patients with ulcerative colitis (UC) suffer from psychiatric disorders, such as major depressive disorder, anxiety, or bipolar disorder, and show specific personality traits. Despite this, there are few data about personality profiles' characterization in UC patients and about correlation of their psychopathological profile with their intestinal microbiota.The aim of our study is to analyze the psychopathological and personality profile of UC patients and correlate it with specific signatures of their gut microbiota. METHODS: This is a prospective interventional longitudinal cohort study. We enrolled consecutive patients affected by UC attending to the IBD Unit of Center for Digestive Disease of "A. Gemelli" IRCCS Hospital in Rome and a group of healthy subjects, matched for specific characteristics. Each patient was evaluated by a gastroenterologist and a psychiatrist. Moreover, all participants underwent psychological tests and a collection of stool samples. RESULTS: We recruited 39 UC patients and 37 healthy subjects. Most patients showed high level of alexithymia, anxiety symptoms, depressive symptoms, as well as neuroticism and hypochondria, with obsessive-compulsive features at the behavioral level, which significantly impaired their quality of life and abilities at work. Gut microbiota analysis in UC patients demonstrated an increase in actinobacteria, Proteobacteria and Saccharibacteria (TM7), with a reduction in verrucomicrobia, euryarchaeota and tenericutes. CONCLUSIONS: Our study confirmed the presence of high levels of psycho-emotional distress in UC patients, alongside alterations of the intestinal microbiota, and highlighted some families and genera of bacteria (Enterobacteriaceae, Streptococcus, Veillonella, Klebsiella, and Clostridiaceae) as potential markers of an altered gut-brain axis in these patients.

Psychiatric disorders are more prevalent in IBD patients than in general population. In this prospective cohort study, we found a correlation between active UC, peculiar psychiatric distress (anxiety and depression above all), and specific taxonomic gut microbiota signatures.

Thymoglobuline plus basiliximab a mixed cocktail to start?

Recent results reported by Ciancio et al. have demonstrated the long term successful use of dual induction therapy in kidney transplant recipients. Our experience using an "induction cocktail", thymoglobuline plus basiliximab, started in 2007 and we have treated 235 patients through the past 10years. In our population, we used a combination of CNIs and MMF or mTORi as maintenance therapy. Our results in term of patient and graft survival, acute rejection rate, renal function and incidence of post-transplant lymphoproliferative disorder support the data reported by Ciancio. We believe that double induction therapy allows on one hand to delay the CNIs introduction, reducing delayed graft function, and on the other hand protects the patient while building the targeted drugs exposures, so reducing the incidence of acute rejection.

Emotional management and quality of life in mother living versus multi-organ donor renal transplant recipients.

The aim of this study was to evaluate psychological differences and quality of life between kidney recipients from living (mother) and multi-organ donor. Overall, 40 patients who had undergone both living (mother) and multi-organ kidney transplantation 3-6 months before were asked to complete four self-report instruments: Toronto Alexithymia Scale, Short Form Health Survey, Regulatory Emotional Self-efficacy, and Attachment Style Questionnaire. A greater difficulty in emotional, social, and mental health functioning was found in recipients receiving kidney from mother living donor. Moreover, in these patients, higher levels of avoidant attachment dimensions were associated with a worse quality of life.

Attachment style predict compliance, quality of life and renal function in adult patients after kidney transplant: preliminary results.

AIM: Aim of this study was to evaluate the association between attachment style, compliance, quality of life and renal function in adult patients after kidney transplantation. METHODS: A total of 43 adult patients who received a kidney transplant more than 3 months before were enrolled and were asked to complete two Self-Report questionnaires: Attachment Style Questionnaire (ASQ-40) and Short Form Health Survey (SF-36). Also compliance was measured using appropriate questions. RESULTS: Linear regression analysis showed associations between the confidence in relationships (ASQ-40) and compliance [beta = -0.37; B = -0.02; t(41) = -2.51; p = 0.02]; aspects of anxious attachment style (ASQ-40) and creatinine levels [beta = 0.3; B = 0.13; t(41) = 2.03; p = 0.04]; aspects of avoidant attachment style (ASQ-40) and compliance [beta = -0.37; B = -3.15; t(41) = -2.35; p = 0.02]. Patients who exhibited avoidant attachment had a significantly better perception of their own general health than patients with anxious [F(2,37) = 6.8; p < 0.05] or secure attachment; however, they had a worse perception regarding role limitations due to emotional problems, compared to patients with anxious attachment [F(2,37) = 6.4; p < 0.05]. DISCUSSION: The results of this study suggest that the evaluation of the attachment style in adult kidney transplant patients can contribute to plan a goal-directed psychological support program for these patients, in order to increase their compliance. The association between aspects of anxious attachment style and creatinine level needs more investigations.

Emotional self-efficacy and alexithymia may affect compliance, renal function and quality of life in kidney transplant recipients: results from a preliminary cross-sectional study.

UNLABELLED: Recent studies show that alexithymia may influence compliance and quality of life in different clinical situations. The aim of this study was to evaluate the associations between alexithymia or emotional self-efficacy and compliance, quality of life (QoL) and renal function in renal transplant patients. METHODS: Forty-three patients were enrolled during a follow-up visit (>3 months post-transplant) and were asked to complete three self-report questionnaires (TAS-20, SF-36, RESE) to answer the following items: "In the past four weeks, how many times did you fail to take your prescribed dose?" and "How would you rate your adherence levels from 0 to 100?" (visual analogue scale). RESULTS: Alexithymia was positively correlated with non-compliance (r=.314; p=.04), and negatively with QoL dimensions. Analysis of variance confirmed that patients with high levels of alexithymia reported a negative perception of their QoL (mental health: F(1,41)=7,6; p=.008) and lower levels of compliance (F(1,41)=12,5; p=.001) compared with patients with low levels of alexithymia. The self-efficacy in the management of negative emotions was significantly correlated (r=-.314; p=.04) with creatinine levels and positively with the QoL (mental health: r=.421; p=.005). DISCUSSION: The inability to recognize and express emotions, as well as the ability to manage negative emotions, may influence compliance and QoL of renal transplant patients. Focused psychological support could be useful in these patients in order to increase their compliance and QoL.

C-terminal trans,trans-muconic acid ethyl ester partial retro-inverso pseudopeptides as proteasome inhibitors.

The development of specific inhibitors of the proteasome represents an important opportunity for new drug therapies. The central role of the multicatalytic complex in the intracellular proteolysis mediated by ubiquitin-proteasome pathway goes to discovery many molecules able to selectively inhibits enzymatic active subsites. Now, we report synthesis and activity of a new partial retro-inverso oligopseudopeptide derivatives bearing a trans,trans-muconic acid ethyl ester pharmacophoric unit at the C-terminal. Some analogues selectively inhibited in µM range the caspase-like (C-L) activity in the ß1 subunit of the proteasome.

Development and validation of the Drug Hypersensitivity Quality of Life Questionnaire.

BACKGROUND: The impact of drug hypersensitivity has never been considered from the patient's perspective, and no questionnaire is currently available for this purpose. OBJECTIVE: To develop and validate a questionnaire specifically designed for the assessment of quality of life in patients with drug hypersensitivity entitled the Drug Hypersensitivity Quality of Life Questionnaire (DrHy-Q). METHODS: During the development procedure, an initial questionnaire of 34 items was generated and administered to 70 patients; the 20 most important items were detected and converted into questions evaluated with a 5-point Likert scale. This provisional questionnaire then underwent a validation procedure to assess its psychometric properties. The DrHy-Q and the Psychological General Well-Being Index (PGWBI) were completed by 365 patients (67.5% female; mean [SD] age, 40 [15] years). RESULTS: Statistical analysis revealed a 1-dimensional structure for the DrHy-Q that explained up to 50.7% of the total variance and showed good levels of internal consistency for the extracted factor (Cronbach α = 0.928). The correlations between the DrHy-Q and the PGWBI scores were low. However, the DrHy-Q scores of patients who experienced anaphylactic shock were significantly higher than the scores from patients with other reactions (analysis of variance; F = 5.991; df = 4; P < .001). The test-retest associations were good (R = 0.995; P < .001). CONCLUSIONS: DrHy-Q met the standards for construct validity, internal consistency, and reliability, indicating that it is appropriate for use alone or in combination with other patient-reported outcome questionnaires to explore the subjective experiences of patients with drug hypersensitivity.
