Mental health, COVID-19 burden and quality of life of kidney transplant recipients two years after the COVID-19 pandemic.

Introduction: Few studies have evaluated the psychological distress of COVID-19 in kidney transplantation and the psychological impact that the COVID-19 pandemic has had on kidney transplant recipients is not yet well understood. The present study aimed to investigate the change in symptom burden and health-related quality of life in the two years after initial assessment, by outlining the change over time of symptoms at 12 and 24 months of follow-up. Methods: This is a follow-up study. We performed a study published in 2021 (phase 1 of COVID-19); of the 89 kidney transplant recipients evaluated in this study, 60 completed the 12 months follow-up (March 2021 June 2021, phase 2 of COVID-19) and 57 completed the 24 months follow-up (March 2022 June 2022, post COVID-19). The same tools as in previous study were administered: the ad hoc questionnaire on emotional state and psychophysical well-being during COVID-19, the Middlesex Hospital Questionnaire (MHQ) to provide a simple and rapid quantification of the psychological and somatic symptoms and the Short Form Health Survey 36 (SF-36) was used to assess health-related quality of life. Results: Compared to the first and second phase of COVID-19, the mean score of quality of life variables were higher in the post COVID-19 phase; thus the recipients physical health, mental health and their perception of their general health improved. Regarding the psychopathology variables the levels of Anxiety, Depression and Phobia in the Post COVID-19 phase decreased, while the Somatization score was higher. Lastly, burden of COVID-19 scores in the third phase, significantly decreased. Discussion: Our study highlights a significant association between mental health and the burden of COVID-19 pandemic in kidney transplant recipients. This study showed, a significant worsening, over time, of some specific symptoms, such as somatization and phobias. However, the results showed that depressive symptoms improved during the study period. Long-term monitoring of kidney transplant recipients therefore remains fundamental. These results confirmed the need to provide integrated multidisciplinary services to adequately address the long-term effects of the COVID-19 pandemic on the mental health of the most vulnerable subjects.

A multicenter prospective observational study appraising the effectiveness of the Supera stent after subintimal recanalization of femoro-popliteal artery occlusion: The SUPERSUB II study.

BACKGROUND: Complex femoropopliteal artery disease represents a challenge. The Supera stent holds the promise of improving the results of endovascular therapy for complex femoropopliteal disease. AIMS: We aimed at appraising the early and long-term effectiveness of the Supera stent after successful subintimal angioplasty (SuperSUB strategy) for complex femoropopliteal lesions. METHODS: We conducted a multicenter, prospective, single-arm observational study including consecutive patients at participating centers in whom Supera was implanted after successful subintimal angioplasty for complex femoropopliteal lesions. RESULTS: A total of 92 patients were included Femoropopliteal arteries were the most common target, and lesion length was 261 ± 102 mm. Most procedures were technically demanding, with antegrade femoral access in 35 (38%) and retrograde distal access in 55 (60%). Supera stent length was 281 ± 111 mm, with 4, 5, and 6 mm devices being most commonly used: 32 (35%), 35 (38%), and 23 (25%), respectively. Technical success was achieved in 100% of subjects, as was clinical success (per subject), whereas procedural success (per subject) was obtained in 98%. At 24 months, freedom from clinically driven target lesion revascularization was 93%, whereas primary patency was 87%. When compared with a similar historical cohort, Supera stent use appeared to be associated with a reduction in resources. CONCLUSION: Use of Supera stent after successful subintimal recanalization of complex lower limb arterial lesions yields favorable procedural results, which are maintained over follow-up, and are associated also with a favorable resource use profile.

Prevention of Delayed Graft Function in Kidney Transplant Recipients through a Continuous Infusion of the Prostaglandin Analogue Iloprost: A Single-Center Prospective Study.

BACKGROUND: Delayed graft function (DGF) is common after kidney transplantation from deceased donors and may significantly affect post-transplant outcomes. This study aimed to evaluate whether an innovative approach, based on the administration of the intravenous prostaglandin analogue iloprost, could be beneficial in reducing the incidence of DGF occurring after kidney transplantation from deceased donors. METHODS: This prospective, randomized (1:1), placebo-controlled study enrolled all consecutive patients who received a kidney transplant from a deceased donor from January 2000 to December 2012 and who were treated in the peri-transplant period with the prostaglandin analogue iloprost at 0.27 µg/min through an elastomeric pump (treatment group) or with a placebo (control group). RESULTS: A total of 476 patients were included: DGF was reported in 172 (36.1%) patients in the entire cohort. The multivariate analysis showed that the donor's age > 70 years (OR 2.50, 95% confidence interval (CI): 1.40-3.05, p < 0.001), cold ischemia time > 24 h (OR 2.60, 95% CI: 1.50-4.51, p < 0.001), the donor's acute kidney injury (OR 2.71, 95% CI: 1.61-4.52, p = 0.021) and, above all, the recipient's arterial hypotension (OR 5.06, 95% CI: 2.52-10.1, p < 0.0001) were the strongest risk factors for developing post-transplant DGF. The incidence of DGF was 21.4% in the treatment group and 50.9% in the control group (p < 0.001). Interestingly, among patients who developed DGF, those who received iloprost had a shorter duration of post-transplant DGF (10.5 ± 8.3 vs. 13.4 ± 6.7, days, p = 0.016). CONCLUSIONS: This study showed that the use of a continuous infusion of iloprost could safely and effectively reduce the incidence of DGF in recipients of deceased-donor kidneys, allowing a better graft functionality as well as a better graft survival.

Living-Donor Uterus Transplantation: A Clinical Review.

Uterus transplantation (UTx) is currently the only available treatment for absolute uterine factor infertility. More than 90 uterus transplantations have been performed worldwide, mostly from living donors. Living-donor (LD) UTx is a challenging surgical procedure since it poses ethical issues, and it is a high-risk and invasive surgery with higher hysterectomy-related risks compared to conventional hysterectomy. A total of 59 living-donor hysterectomies have been reported in the literature, including 35 performed with a laparotomic approach, 20 with a robotic approach and 4 with a laparoscopic approach. The mean donor age was 45.6 ± 9.1 years, and 22 were unrelated with the recipients, 34 were emotionally related (27 mothers, 5 sisters, 2 mother's sisters). The mean recipient age was 28.8 ± 4.5 years. Mayer-Rokitansky-Küster-Hauser syndrome was the most common indication for uterus transplant. Robotic living-donor hysterectomy had the longest operative time but resulted in a lower blood loss and postoperative stay compared to laparotomic and laparoscopic approaches. Twenty-nine births from LD-UTx have been reported, four after robotic living-donor hysterectomy and twenty-five after a laparotomic procedure. UTx is now an effective treatment for women with UFI. While living-donor UTx in some cases may be considered an experimental procedure, it offers the extraordinary possibility to give women the opportunity to have a pregnancy. Many efforts should be made to reduce the potential risks for donors, including the use of mini-invasive techniques, and the efficacy of UTx in the recipients, giving the potential harm of immunosuppression in a recipient of a non-life-saving organ.

Nonadherence to Immunosuppressants Among Transplant Recipients: Emotional Intelligence as a Predictive Factor During COVID-19 Pandemic.

Purpose: To evaluate the association between emotional intelligence and fear of COVID-19 on self-reported adherence, based on a cross-sectional design. Patients and Methods: Transplants recipient of both sexes aged 23-75 years old were evaluated at the Organ Transplant Unit, University Hospital of Catania, Italy. Data were analyzed using frequency, descriptives, Spearman and Pearson correlations, Chi-square goodness of fit test, and linear regression. Self-reported adherence was estimated with the Basel Assessment of Adherence with Immunosuppressive Medication Scale (BAASIS). Emotional intelligence and fear of COVID were, respectively, measured with the Emotional Intelligence Scale (EIS) and Multidimensional Assessment of COVID-19 Related Fears Scale (MAC-RF). This was a cross-sectional study of kidney transplant recipients. In reporting this study the authors followed the STROBE guidelines. Results: A correlation was found between EIS and MAC and between EIS and adherence but there was no correlation between MAC and adherence. A linear regression model was also conducted using a stepwise method, which indicated that EIS was a significant predictor of adherence (p <0.05). Conclusion: This study was found that EIS is a predictor of adherence to treatment in transplant patients. Fear of COVID, while positively correlated to EIS, is not correlated to the adherence's outcome, possibly due to the proper follow-up performed to the patients. Indeed, according to these results, we suggest to provide good follow-ups with recipients, with interviews also based on self-regulation and awareness.

Live Birth from Cryopreserved Oocyte After Uterus Transplantation: A Case Report.

BACKGROUND Important legal and ethical issues must be addressed in the practice of uterus transplantation, because it is a non-life-saving intervention. In all cases reported in the literature so far, uterus transplantation is preceded by oocyte retrieval, fertilization of the collected oocytes, and subsequent freezing of the embryos produced. This element should be considered because of the potential ethical, legal, and moral implications related to the existence and fate of supernumerary embryos in the event of transplantation failure. CASE REPORT The Italian Research Project for Uterus Transplantation from a brain-dead donor was approved in 2018 (No. 1438/CNT2018). A 28-year-old patient with Mayer-Rokitansky-Küster-Hauser syndrome, ectopic ovaries, and good ovarian reserve received uterus transplantation in 2020 after oocyte retrieval with laparoscopic assistance. Metaphase oocytes were cryopreserved and thawed after the successful transplantation to perform in vitro fertilization followed by embryo transfer. The pregnancy course was regular, without symptoms until week 30, when PCR positivity for SARS-CoV-2 was recorded. The patient underwent an emergency cesarean delivery at 34 weeks' gestation because of fever and the appearance of regular uterine contractions. An infant was born alive and vital at 34 weeks of pregnancy and weighed 1725 g. The newborn was discharged in good condition and with a body weight of 2740 g. CONCLUSIONS This case report shows that cryopreservation of oocytes can overcome the ethical issue related to embryo retrieval before a successful uterus transplantation can be demonstrated. Our result supports the possibility of bypassing embryo freezing before ascertaining the success of uterus transplantation.

ZILVERPASS Study: ZILVER PTX Stent versus Prosthetic Above-the-Knee Bypass Surgery in Femoropopliteal Lesions, 5-year Results.

PURPOSE: To report the 60-month safety and effectiveness results of a multicenter, prospective, randomized controlled trial comparing the ZILVER PTX paclitaxel-eluting stent to prosthetic above-the-knee bypass for the treatment of symptomatic TransAtlantic Inter-Society Consensus (TASC) C and D femoropopliteal lesions. MATERIALS AND METHODS: Patients were enrolled between October 2013 and July 2017. One of the secondary outcomes was primary patency at 60 months, defined as no evidence of binary restenosis or occlusion within the target lesion or bypass graft based on a duplex ultrasound peak systolic velocity ratio < 2.4 and no clinically-driven target lesion revascularization (TLR) in endovascular cases or reintervention to restore flow in the bypass at 60 months. Survival rates after 5 years were also analyzed. RESULTS: 220 patients (mean age 68.6 ± 10.5 years; 159 men) were included and randomized to ZILVER PTX (n = 113, 51.40%) or BYPASS group (n = 107, 48.60%). The 60-month primary patency rate was 49.3% for the ZILVER PTX group versus 40.7% for the bypass group (p = 0.6915). Freedom from TLR was 63.8% for the ZILVER PTX group versus 52.8% for the bypass group (p = 0.2637). At 5 years, no significant difference in survival rate could be seen between the ZILVER PTX and the bypass group (69.1% vs. 71% respectively, p = 0.5503). CONCLUSION: Even at 5 years, non-inferior safety and effectiveness results of the ZILVER PTX could be seen. These findings confirmed that the use of ZILVER PTX stents can be considered as a valid alternative for bypass surgery when treating long and complex femoropopliteal lesions.

Attachment and parental bond: impact on psychopathology, mental health and quality of life of hemodialysis patients: a cross-sectional study.

BACKGROUND: Attachment theory represents a reference model for understanding better how pre-existing personality factors can influence the coping with some chronic conditions. The onset of a chronic disease can represent a "threat" to the relationships between the subject and parental figures according to the type of bond that already exists. The aim of our study was to explore attachment styles in a sample of hemodialysis patients, hypothesizing that a secure attachment bond can constitute a protective factor for the quality of life and mental health in this type of patients. DESIGN: We used a cross-sectional design. METHODS: Fifty hemodialysis patients were given the following tests: Attachment Style Questionnaire (ASQ) to assess attachment styles, Parental Bonding Instrument (PBI) to assess parental bonding, Short Form Health Survey-36 (SF-36) for perceived quality of life and Middlesex Hospital Questionnaire (MHQ) to detect key psychological symptoms and relevant traits. RESULTS: The results showed that secure attachment style correlated with good general health (r = 0.339; p < 0.05), good mental health (r = 0.547; p < 0.001) and mental component scale (r = 0.373; p < 0.05) of SF-36. Secure attachment was also significantly associated with mental health (B = 1.104; p = .002) of the SF-36. CONCLUSIONS: The results confirmed the positive role of a secure attachment style for adequate psychological health. Early identification of patients with dysfunctional attachment styles will make it possible to offer them targeted interventions to improve their ability to accept, adapt and manage the disease and to maintain adequate psychological well-being.

ZILVERPASS Study: ZILVER PTX Stent vs. Bypass Surgery in Femoropopliteal Lesions, 3 year results and economic analysis.

BACKGROUND: To report the 3-year safety and effectiveness results of a multicenter, prospective, randomized controlled trial comparing the ZILVER PTX paclitaxel-eluting stent to surgical bypass and to conduct a health economic analysis up to 3-year follow-up of the two treatment modalities. METHODS: This is a study in symptomatic TransAtlantic Inter-Society Consensus (TASC) C and D femoropopliteal lesions comparing endovascular ZILVER PTX stenting vs. surgical bypass surgery using a prosthetic graft (ClinicalTrials.gov identifier NCT01952457). Between October 2013 and July 2017, 220 patients (mean age 68.6±10.5 years; 159 men) were enrolled and randomized to the ZILVER PTX treatment group (113, 51.40%) or the bypass treatment group (107, 48.60%). One of the secondary outcomes was primary patency at 3-year, defined as no evidence of binary restenosis or occlusion within the target lesion or bypass graft based on a duplex ultrasound peak systolic velocity ratio <2.4 and no clinically-driven target lesion revascularization (TLR) in endovascular cases or reintervention to restore flow in the bypass. An economic analysis was conducted to analyze the cost differences between ZILVER PTX and bypass, which shows the perspective of the public authority/organization that pays for healthcare in the two countries (payor), Germany and USA. RESULTS: The 3-year primary patency rate was 53.30% (95% CI 61.40% to 45.20%) for the ZILVER PTX group vs. 58.20% (95% CI 67.10% to 49.30%) for the bypass arm (P=0.9721). Freedom from TLR at 3-year was 62.80% (95% CI 72.60% to 53%) for the ZILVER PTX group vs. 65.30% (95% CI 75.40% to 55.20%) for the bypass group (P=0.635). There was also no significant difference (P=0.358) in survival rate at 3-year between the ZILVER PTX group 78.50%, (95% CI to 87.70% to 69.30%) and the bypass group 87.40% (95% CI 97.6% to 77.2%). None of the deaths was categorized as related to the procedure or device. The economic analysis, taking into account procedural-, hospitalization- and reintervention costs, showed a clear cost-benefit for Zilver PTX in both investigated countries up to 3-year follow-up: Germany (Bypass €9446 per patient versus ZILVER PTX €5755) and USA (Bypass $26,373 per patient versus ZILVER PTX $19,186). CONCLUSIONS: The non-inferior safety and effectiveness results of the ZILVER PTX stent were associated with lower costs for the payer and confirmed that ZILVER PTX stent treatment can be considered as a valid alternative for bypass surgery in long and complex femoropopliteal lesions.

Guidelines on the management of abdominal aortic aneurysms: updates from the Italian Society of Vascular and Endovascular Surgery (SICVE).

The objective of these Guidelines was to revise and update the previous 2016 Italian Guidelines on Abdominal Aortic Aneurysm Disease, in accordance with the National Guidelines System (SNLG), to guide every practitioner toward the most correct management pathway for this pathology. The methodology applied in this update was the GRADE-SIGN version methodology, following the instructions of the AGREE quality of reporting checklist as well. The first methodological step was the formulation of clinical questions structured according to the PICO (Population, Intervention, Comparison, Outcome) model according to which the Recommendations were issued. Then, systematic reviews of the Literature were carried out for each PICO question or for homogeneous groups of questions, followed by the selection of the articles and the assessment of the methodological quality for each of them using qualitative checklists. Finally, a Considered Judgment form was filled in for each clinical question, in which the features of the evidence as a whole are assessed to establish the transition from the level of evidence to the direction and strength of the recommendations. These guidelines outline the correct management of patients with abdominal aortic aneurysm in terms of screening and surveillance. Medical management and indication for surgery are discussed, as well as preoperative assessment regarding patients' background and surgical risk evaluation. Once the indication for surgery has been established, the options for traditional open and endovascular surgery are described and compared, focusing specifically on patients with ruptured abdominal aortic aneurysms as well. Finally, indications for early and late postoperative follow-up are explained. The most recent evidence in the Literature has been able to confirm and possibly modify the previous recommendations updating them, likewise to propose new recommendations on prospectively relevant topics.

[Evolution of transcatheter aortic valve implantation from a high-volume Italian center: report of 2058 procedures over 15-year experience]. / Evoluzione dell'impianto transcatetere di valvola aortica in un centro italiano ad alto volume: report di 2058 procedure in 15 anni di esperienza.

BACKGROUND: To assess the longitudinal changes in transcatheter aortic valve implantation (TAVI) practice and patients' outcomes in a high-volume Italian center. METHODS: We analyzed all patients undergoing TAVI at our Institution from June 2007 to August 2021. We stratified the overall population considering four time periods according to procedural advancements and changes in clinical practice: period 1 (2007-2009, n=107) vs period 2 (2010-2014, n=449) vs period 3 (2015-2019, n=864) vs period 4 (2019-2021, n=638). Baseline and procedural characteristics, and in-hospital outcomes among the four groups were compared. RESULTS: A total of 2058 patients underwent TAVI receiving all the available devices. Patients had a median age of 82 years (78-85) with no differences among time periods. A stepwise reduction of median Society of Thoracic Surgeons mortality risk score (3.7 [2.8-5.3] vs 3.6 [2.6-5.4] vs 3.6 [2.5-5.5] vs 3.3 [2.2-4.9]; p=0.01) was observed. In-hospital all-cause-death (7.5% vs 5.1% vs 2.9% vs 3.0%; p<0.05), major stroke (4.7% vs 0.7% vs 1.0% vs 0.8%; p<0.05), major vascular complications (17.8% vs 8.7% vs 10.5% vs 5.8%; p<0.05) and permanent pacemaker implantation (23.4% vs 12.0% vs 8.7% vs 8.8%; p<0.05) rates significantly lowered over time. Device success markedly improved (80.4% vs 87.1% vs 95.0% vs 96.3%; p<0.05) with significant improvement of paravalvular regurgitation after TAVI (moderate-to-severe 16.8% vs 8.1% vs 0.7% vs 0.2%; mild 61.4% vs 38.2% vs 38.5% vs 25.6%; p<0.05). CONCLUSIONS: All-cause death and in-hospital outcomes of patients undergoing TAVI significantly improved accordingly to technical advancements and changes in clinical practice over 15-year experience.

Obesity and bariatric surgery in kidney transplantation: A clinical review.

Obesity is increasing worldwide, and this has major implications in the setting of kidney transplantation. Patients with obesity may have limited access to transplantation and increased posttransplant morbidity and mortality. Most transplant centers incorporate interventions aiming to target obesity in kidney transplant candidates, including dietary education and lifestyle modifications. For those failing nutritional restriction and medical therapy, the use of bariatric surgery may increase the transplant candidacy of patients with obesity and end-stage renal disease (ESRD) and may potentially improve the immediate and late outcomes. Bariatric surgery in ESRD patients is associated with weight loss ranging from 29.8% to 72.8% excess weight loss, with reported mortality and morbidity rates of 2% and 7%, respectively. The most commonly performed bariatric surgical procedures in patients with ESRD and in transplant patients are laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass. However, the correct timing of bariatric surgery and the ideal type of surgery have yet to be determined, although pretransplant LSG seems to be associated with an acceptable risk-benefit profile. We review the impact of obesity on kidney transplant candidates and recipients and in potential living kidney donors, exploring the potential impact of bariatric surgery in addressing obesity in these populations, thereby potentially improving posttransplant outcomes.

Abdominal wall complications after kidney transplantation: A clinical review.

INTRODUCTION: Abdominal wall complications are common after kidney transplantation, and although they have a minor impact on patient and graft survival, they increase the patient's morbidity and may have an impact on quality of life. Abdominal wall complications have an overall incidence of 7.7-21%. METHODS: This review will explore the natural history of abdominal wall complications in the kidney transplant setting, with a special focus on wound dehiscence and incisional herni, with a particular emphasis on risk factors, clinical characteristics, and treatment. RESULTS: Many patient-related risk factors have been suggested, including older age, obesity, and smoking, but kidney transplant recipients have an additional risk related to the use of immunosuppression. Wound dehiscence usually does not require surgical intervention. However, for deep dehiscence involving the fascial layer with concomitant infection, surgical treatment and/or negative pressure wound therapy may be required. CONCLUSIONS: Incisional hernia (IH) may affect 1.1-18% of kidney transplant recipients. Most patients require surgical treatment, either open or laparoscopic. Mesh repair is considered the gold standard for the treatment of IH, since it is associated with a low rate of postoperative complications and an acceptable rate of recurrence. Biologic mesh could be an attractive alternative in patients with graft exposition or infection.

Colorectal Cancer after Kidney Transplantation: A Screening Colonoscopy Case-Control Study.

The incidence of colorectal cancer in kidney transplant recipients has been previously reported with conflicting results. In this study, we investigated if the incidence of colorectal advanced neoplasms in kidney transplant recipients, evaluated with screening colonoscopy, was higher than in healthy individuals. One-hundred sixty kidney transplant recipients undergoing screening colonoscopy were compared with 594 age- and sex-matched healthy individuals. Advanced colorectal neoplasia was found in 22 patients (13.7%), including four patients (2.5%) with colorectal cancer. Compared with the healthy population, kidney transplant recipients did not have an increased risk of developing a colorectal cancer (OR 0.69; 95% CI 0.236-2.063, p = 0.688) although it developed at a younger age. In contrast, kidney transplant recipients had a higher risk of developing an advanced adenoma compared with the control group (OR 1.65; 95% CI 0.930-2.981, p = 0.04). In conclusion, kidney transplant recipients did not have an increased incidence of colorectal cancer compared with healthy population. However, transplant patients displayed a higher incidence of colorectal adenomas, suggesting that screening colonoscopy in kidney transplant recipients should be expanded to include even younger recipients (<50 years old).

Quality of Life and Mental Health in Kidney Transplant Recipients During the COVID-19 Pandemic.

Introduction: The COVID-19 pandemic has led to an increase in mental distress such as phobic anxieties, depressive reactions, hypochondriac concerns, and insomnia. Among the causes are risk of infection and prolonged isolation. This study aimed to analyze psychopathological variables and dysfunctional lifestyles related to adequate therapeutic compliance in kidney transplant recipients. Methods: Eighty-nine kidney transplant recipients were evaluated using an online protocol including a questionnaire concerning habits, lifestyle and psychophysical well-being in the COVID-19 period, the Middlesex Hospital Questionnaire (MHQ) and the SF-36 Health Survey to evaluate the perception of their physical and emotional health. Results: Of these recipients, 28.6% reported changes in their emotional state. Sleep quality deteriorated for 16.1%. Anxiety (M = 5.57, r = 0.33; p < 0.05) and phobia (M = 6.28, r = 0.26; p < 0.05) correlated with concerns related to physical health. There was no negative impact on relational and socialization aspects, which were likely well compensated by the use of remote technologies such as video phone calls, Zoom meetings and use of computers (r = 0.99; r = 0.80; p < 0.05). Conclusions: It would be interesting to maintain this remote visit and interview mode to monitor, on a clinical and psychological level, kidney transplant recipients in subsequent follow-ups (12-18 months), to check for any psychopathological disorders and/or changes in their resilience capacity in the Coronavirus emergency.

An upfront combined strategy for endovascular haemostasis in transfemoral transcatheter aortic valve implantation.

BACKGROUND: Vascular complications still represent an important issue after transcatheter aortic valve implantation (TAVI). AIMS: The aim of this study was to evaluate the effectiveness of upfront use of an adjunctive Angio-Seal (AS) plug-based system on top of suture-based devices (SBDs) for endovascular haemostasis after transfemoral (TF) TAVI. METHODS: From January 2019 to April 2020, 332 consecutive patients with preprocedural computed tomography angiography (CTA) assessment underwent fully percutaneous TF-TAVI. The primary outcomes were 30-day major vascular complications and major or life-threatening (LT) bleeding due to endovascular closure system failure. A total of 246 TF-TAVI patients (123 pairs), undergoing either isolated SBD or SBD+AS, were matched using the propensity-score method. RESULTS: At 30 days, patients receiving SBD+AS had lower rates of major/LT bleeding (1.6% vs 8.9%, odds ratio [OR] 0.17, 95% confidence interval [CI]: 0.04-0.78; p<0.01) and major vascular complications (1.6% vs 8.9%, OR 0.17, 95% CI: 0.04-0.78; p<0.01). In addition, the use of SBD+AS was associated with a significant cost saving related to the vascular event (mean difference -315.3 € per patient, 95% CI: -566.4 € to -64.1 €; p=0.01), and a higher probability of next-day discharge (NDD) after TAVI (30.9% vs 16.3%, OR 2.30, 95% CI: 1.25-4.25; p<0.01). No difference in all-cause 30-day mortality was observed (3.3% vs 1.6% for SBD and SBD+AS groups, respectively, OR 0.49, 95% CI: 0.09-2.74; p=0.41). CONCLUSIONS: An upfront combined strategy with an additional AS plug-based device on top of SBDs was shown to reduce major vascular complications and major/LT bleeding due to closure system failure after TF-TAVI. This approach was associated with a cost saving and with a higher probability of NDD compared to the use of isolated SBD. Visual summary. Effectiveness of the upfront combined strategy for endovascular haemostasis in transfemoral transcatheter aortic valve implantation using Angio-Seal on top of a suture-based device (SBD) versus the isolated use of SBD. LT: life-threatening; TF-TAVI: transfemoral transcatheter aortic valve implantation.

Post-transplant colitis after kidney transplantation: clinical, endoscopic and histological features.

Chronic immunosuppression may increase the risk of post-transplant infection and medication-related injury and may also be responsible for the increased risk of gastrointestinal complications in kidney transplant recipients. Differentiating the various forms of post-transplant colitis is challenging, since most have similar clinical and histological features. This study evaluated the incidence of post-transplant gastrointestinal complications during screening colonoscopy. Kidney transplant recipients undergoing a colonoscopy for any reasons in the period 2014-2018 were included. Among the 134 patients completing the colonoscopy, 74 patients (56%) had an abnormal finding: an adenoma was found in 25 patients (18.6%), while 19 patients (14.1%) had colitis. Mycophenolic acid/related colitis was the most common colitis (6%), while 7 patients (5.2%) developed a de novo inflammatory bowel disease. Patients with post-transplant colitis were younger and with shorter time from transplant compared to patients without colitis. In conclusions, immunosuppression may predispose kidney transplant recipients to an increased risk of post-transplant colitis. Diagnostic colonoscopy should be encouraged in all transplant patients with refractory diarrhea and gastrointestinal symptoms to allow a prompt diagnosis and a timely treatment, finally improving the quality of life and long-term outcomes of affected patients.

Gastrointestinal complications after kidney transplantation.

Gastrointestinal complications are common after renal transplantation, and they have a wide clinical spectrum, varying from diarrhoea to post-transplant inflammatory bowel disease (IBD). Chronic immunosuppression may increase the risk of post-transplant infection and medication-related injury and may also be responsible for IBD in kidney transplant re-cipients despite immunosuppression. Differentiating the various forms of post-transplant colitis is challenging, since most have similar clinical and histological features. Drug-related colitis are the most frequently encountered colitis after kidney transplantation, particularly those related to the chronic use of mycophenolate mofetil, while de novo IBDs are quite rare. This review will explore colitis after kidney transplantation, with a particular focus on different clinical and histological features, attempting to clearly identify the right treatment, thereby improving the final outcome of patients.
