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

Abstract 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.

Allergen avoidance in the treatment of dust-mite allergy and asthma.

House-dust-mite allergen is one of the primary causes of asthma. In many instances, asthma is an immunoglobulin gamma E mediated atopy (i.e., allergenspecific hypersensitivity) that leads to non-specific bronchial hyper-reactivity and subsequent symptom manifestations. These symptoms may range from an annoying cough to full-blown respiratory failure. Allergenavoidance measures should be a primary mode of treatment for atopic asthmatics. This article focuses on the dust-mite allergen and its relationship to asthma. It details specific avoidance measures that should be implemented by the majority of asthmatics. Studies are cited that support the aggressive use of these measures to decrease allergen exposure, and to subsequently prevent or significantly reduce asthma symptoms. When health care providers have a better understanding of avoidance measures and the rationale underlying their use, these measures are more likely to be valued and given greater emphasis in education and treatment plans. Renewed emphasis on an immuno-modulatory approach to asthma treatment may help to reverse the rise in asthma morbidity and mortality rates.

Evolution of Causes of Mortality in Renal Transplantation in the Last 10 Years

INTRODUCTION Improvements in immunosuppressive therapy have significantly changed results of organ transplantation. The aim of this study was to review the causes of mortality among our renal transplant population. METHODS This study population included 750 patients who underwent kidney transplantation between 1970 and 2007. During the follow-up, we recorded all causes of death and major cardiovascular events: stroke, myocardial infarction, angina pectoris, and cardiac death were considered major adverse cardiovascular events (MACE) The occurrence of MACE was related to wellestablished cardiovascular risk factors-age, sex, arterial blood pressure, diabetes, renal function, cardiovascular body mass index, history, or dyslipidemia measured at 6 months, as well as 5 and 10 years after transplantation. At these times we also calculated the INDANA, Framingham, and ltalian Heart Project scores. RESULTS The median follow-up was 63 months and mean age was 45 +/- 11 years. The median waiting time for transplant was 34 months. During follow up, 22 patients (6.1%) developed MACE, with 2 (0.55%) events within 6 months 10 (3.1%) between 6 months and 5 years, and 10 (6.5%) between 5 and 10 years. The INDANA score at all the time periods was significantly different among patients with vs without MACE (P < .0001), whereas no significant difference was observed using the Framinghan or the Italian Heart Project scores (P < .11). CONCLUSION Our study indicated that the INDANA scoring system better predicted the risk of MACE as approved to the Framinghan or Italian Heart Project systems. The INDANA score might be used to plan selective cardiovascular screening among recipients.

One-shot versus multidose perioperative antibiotic prophylaxis after kidney transplantation: A randomized, controlled clinical trial

BACKGROUND There is no consensus on the optimal perioperative antibiotic prophylaxis regimen for renal transplant recipients. Some studies have reported that irrigation of the wound at the time of closure without systemic antibiotics may suffice to minimize the risk for surgical site infection (SSI), but many centers still use long-term, multidose regimens in which antibiotics are administered until removal of foreign bodies occur, such as the urethral catheter, drain and central line. METHODS We designed a prospective, randomized, multicenter, controlled trial to compare a single dose versus a multidose regimen of systemic antibiotic prophylaxis in adult, nondiabetic, non-morbidly obese patients undergoing renal transplantation. The primary endpoint was the incidence of SSI; the assessment of other infection in the first postoperative month was the secondary endpoint. RESULTS Two hundred five patients were enrolled and randomized to receive either a single (n = 103) or multidose antibiotic regimen (n = 102) for prophylaxis. The incidences of SSI and urinary tract infection were similar in both groups. CONCLUSION As the dramatic increase in antibiotic resistance has mandated the implementation of global programs to optimize the use of antibiotic agents in humans, we believe that the single dose regimen is preferred, at least in nondiabetic, non-morbidly obese, adult renal transplant recipients.

Expanding the Living Donor Pool, “Ist Act”: Analysis of the Causes of Exclusion of Potential Kidney Donors

BACKGROUND The evaluation of a potential living kidney donor (LKD) leads to exclusion of at least 50% of candidates. The aim of this study was to analyze the reasons for exclusion of potential LKDs referred to our center. METHODS We retrospectively analyzed historic and clinical data of all potential LKDs who were evaluated over 7 years from January 2005 to March 2012. Data were obtained by review of an electronic database. RESULTS Among 79 (50 female, 29 male) candidates, 24 (30.3%) successfully donated, comprising 22 related and 2 unrelated donors. We excluded 45 (56.9%), and 10 (12.6%) are actively undergoing evaluation. Reasons for exclusion were medical (n = 14; 31%), nonmedical (n = 18; 40%), positive cross-match (n = l7.7%), pregnancy (n = 2; 4.4%), and other reasons (n = 3; 6.6%). Of the 14 donors excluded for medical reasons, 75.8% were due to diabetes, cardiovascular disease, hypertension, or obesity and 21.5% to inadequate renal function, malignancy, or liver disease. Of the 18 (40%) excluded for nonmedical reasons, 6 (33.3%) were because the intended recipient received a deceased-donor transplantation before the evaluation could be completed, 5 (27.7%) because the recipient was no longer a candidate for transplantation, 5 (27.7%) because of donor withdrawal, and 2 (11.1%) for other reasons. CONCLUSIONS Positive cross-match and deceased-donor transplantation during the evaluation process were the 2 most common reasons for LKD exclusion. Evaluation of potential LKDs is time consuming, requiring a remarkable amount of human and material resources. A dedicated pathway for the diagnostic work-up of LKDs may speed- the evaluation process and improve its efficiency, use of ABO-incompatible or paired-exchange donations may increase the yield of donor organs.

Tacrolimus plus mycophenolate mofetil vs. cyclosporine plus everolimus in deceased donor kidney transplant recipients: three-yr results of a single-center prospective clinical trial.

We compared in kidney transplantation two immunosuppressive regimens: tacrolimus plus mycophenolate mofetil (MMF) (TAC) and everolimus plus low‐dose cyclosporine (EVE). Sixty consecutive patients received TAC (30 patients) or EVE (30 patients) as immunosuppressive regimen; all subjects also received induction with basiliximab and corticosteroids. After three‐yr follow‐up, no difference was found in patient and graft survival (PTS: TAC: 97% vs. EVE: 100%; GS: TAC: 93% vs. EVE: 93%). The incidence of acute rejection was higher in the EVE group but the difference was not statistically significant (17% vs. 23%, p = ns). Patients in EVE showed higher serum cholesterol (205 ± 41 vs. 235 ± 41 mg/dL, p = 0.0012) and lower hemoglobin concentration (13.6 ± 1.4 vs. 12.4 ± 1.9, p = 0.01). Renal function was not significantly different in the two groups (3 Y creatinine: TAC 1.4 ± 0.8 vs. EVE 1.6 ± 0.8 mg/dL, p = ns). Treatment discontinuation was higher in the EVE group (TAC 17 vs. EVE 36%, p = ns). Our data show that in the middle‐term follow‐up, an immunosuppressive regimen with tacrolimus plus MMF has a similar efficacy and safety profile in comparison with the combination of low‐exposure cyclosporine plus everolimus. Further follow up could evidence the benefits related to the anti‐proliferative effects of everolimus.

Once Daily Everolimus Is Safe and Effective in De Novo Renal Transplant Recipients: Six-Month Results of a Pilot Study

INTRODUCTION The half-life of everolimus is approximately 28 hours, but everolimus is normally administered twice a day. The aim of this prospective, single-center, exploratory study was to compare the efficacy and safety of a once a day (OD) everolimus regimen versus the standard twice a day regimen (BID) for immunosuppressive therapy in renal transplantation. METHODS Forty de novo renal transplant recipients prospectively assigned to OD (n = 21) or BID (n = 19) were followed for 6 months. In the OD group, everolimus was given orally once a day to target a trough blood level of 2-6 ng/mL. In the BID, group everolimus was given twice a day to target a trough blood level of 3-12 ng/mL. All patients also received induction treatment with basiliximab and low-dose calcineurin inhibitors. RESULTS At 6 months follow-up, patient and graft survivals were 100%; renal function and acute rejection rates were similar between the 2 regimens. Patients in the OD group showed significantly lower cholesterol and triglyceride levels compared with those in the BID group, namely, total cholesterol level, OD 212 +/- 54 versus BID 249 +/- 59 mg/dL (P < .05), and serum triglycerides, OD 162 +/- 72 versus BID 245 +/- 133 mg/dL (P < .02). DISCUSSION This study showed that OD administration of everolimus provided excellent patient and graft survivals and good renal function without an increased incidence of acute rejection episodes. The lipid profile was significantly better among patients receiving everolimus OD. These findings suggested that everolimus can be safely administered once a day.

The reduction of left ventricular hypertrophy after renal transplantation is not influenced by the immunosuppressive regimen.

BACKGROUND Cardiovascular (CV) disease is the first cause of death after kidney transplantation. Left ventricular hypertrophy (LVH) is one of the main CV risk factors. It has been reported that the antiproliferative properties of everolimus (EVE) treatment may decrease left ventricular mass. The aim of this study was to evaluate the evolution of LVH in two groups of kidney transplant recipients receiving immunosuppressive treatment with low-dose calcineurin inhibitor (CNI) + EVE or CNI + mycophenolate mofetil (MMF). METHODS We evaluated 104 patients of mean age 47.5 ± 13.1 years who underwent kidney transplantation between January 2006 and December 2009 pretransplant by echocardiography, which was repeated every year for 3 years during which all patients continued the initial therapy. Over the 3-year period 76 subjects were treated with MMF, and 28 with EVE. We recorded left ventricular end-diastolic diameter (LVEDD), interventricular septum thickness in diastole (IVSTD), left ventricular posterior wall thickness in diastole (LVPWD), left ventricular end-diastolic volume and end-systolic volume during the follow-up echocardiographic evaluations. RESULTS No differences in the evolution of the echocardiographic parameters were observed between the two groups-MMF versus EVE group: LVEDD, 50.3 ± 5.1 versus 51.2 ± 6.7 mm; IVSTD, 11.2 ± 1.9 versus 11.3 ± 2 mm; LVPWD, 10.2 ± 1.9 versus 10.5 ± 1.7 mm; relative wall thickness, 0.041 ± 0.08 versus 0.42 ± 0.08; ejection fraction, 63 ± 6% versus 61 ± 5%; and left ventricular mass index, 113 ± 28.9 versus 121.9 ± 39.4 g/m(2), respectively. Compared with pretransplant echocardiographic evaluations, similar reductions in left ventricular mass index were noted in both groups after transplantation. CONCLUSIONS We observed that after renal transplantation there was a reduction of the LVH respect to the pretransplant dialytic status. The two immunosuppressive regimen did not influence the evolution of post-transplant LVH.

Are there any relations among transplant centre volume, surgical technique and anatomy for donor graft selection? Ten-year multicentric Italian experience on mini-invasive living donor nephrectomy.

Background Selection of the right or left living donor kidney for transplantation is influenced by many variables. In the present multi centric study including 21 Italian transplant centres, we evaluated whether centre volume or surgical technique may influence the selection process. Methods Intra- and perioperative donor data, donor kidney function, and recipient and graft survival were collected among 693 mini-invasive living donor nephrectomies performed from 2002 to 2014. Centre volume (LOW, 1-50 cases; HIGH, >50 cases) and surgical technique (FULL-LAP, full laparoscopic and robotic; HA-LAP, hand-assisted laparoscopy; MINI-OPEN, mini-lumbotomy) were correlated with selection of right or left donor kidney and with donor and recipient outcome. Results HIGH-volume centres retrieved a higher rate of donor right kidneys (29.3% versus 17.6%, P < 0.01) with single artery (83.1% versus 76.4%, P < 0.05) compared with LOW-volume centres. Surgical technique correlated significantly with rate of donor right kidney and presence of multiple arteries: MINI-OPEN (53% and 13%) versus HA-LAP (29% and 22%) versus FULL-LAP (11% and 23%), P < 0.001 and P < 0.05, respectively. All donors had an uneventful outcome; donor bleeding was more frequent in LOW-volume centres (4% versus 0.9%, P < 0.05). Conclusions Centre volume and surgical technique influenced donor kidney side selection. Donor nephrectomy in LOW-volume centres was associated with higher risk of donor bleeding.
