Deceased donors with previous hepatitis C infection may represent a safe resource to expand the donor pool. When allocated to serology-matched recipients, kidney transplantation from donors with hepatitis C may result in an excellent short-term outcome and a significant reduction of time on the waiting list. Special care must be dedicated to the pre-transplant evaluation of potential candidates, particularly with regard to liver functionality and evidence of liver histological damage, such as cirrhosis, that could be a contraindication to transplantation. Pre-transplant antiviral therapy could be useful to reduce the viral load and to improve the long-term results, which may be affected by the progression of liver disease in the recipients. An accurate selection of both donor and recipient is mandatory to achieve a satisfactory long-term outcome.展开更多

Studies have identified many problems that may affect adaptation to the transplanted condition and postoperative compliance. The psychological implications of transplantation have important consequences even on strictly physical aspects. Organ transplantation is very challenging for the patient and acts as an intense stressor stimulus to which the patient reacts with neurotransmitter and endocrine-metabolic changes. Transplantation can result in a psychosomatic crisis that requires the patient to mobilize all bio-psychosocial resources during the process of adaptation to the new foreign organ which may result in an alteration in self-representation and identity, with possible psychopathologic repercussions. These reactions are feasible in mental disorders, e.g., post-traumatic stress disorder, adjustment disorder, and psychosomatic disorders. In organ transplantation, the fruitful collaboration between professionals with diverse scientific expertise, calls for both a guarantee for mental health and greater effectiveness in challenging treatments for a viable association between patients, family members and doctors. Integrated and multidisciplinary care should include uniform criteria and procedures for standard assessments, for patient autonomy, adherence to therapy, new coping strategies and the adoption of more appropriate lifestyles.展开更多

Here we report a rare case of idiopathic giant esophageal ulcer in a kidney transplant recipient. A 37-year-old female presented with a one-week history of odynophagia and weight loss. Upon admission, the patient presented cold sores, and a quantitative cytomegalovirus polymerase chain reaction was positive(105 copies/ml). An upper endoscopy demonstrated the presence of a giant ulcer. Serological test and tissue biopsies were unable to demonstrate an infectious origin of the ulcer. Immunosuppression was reduced and everolimus was introduced. An empirical i.v. therapy with acyclovir was started, resulting in a dramatic improvement in symptoms and complete healing of the ulcer. Only two cases of idiopathic giant esophageal ulcer in kidney transplant recipients have been reported in the literature; in both cases, steroid therapy was successful without recurrence of symptoms or endoscopic findings. However, this report suggests that correction of immune imbalance is mandatory to treat such a rare complication.展开更多

METHODS The study examined the psychological variables likely responsible for the non-adherent behavior using a psychological-psychiatric assessment, evaluation of the perception of patients' health status, and an interview regarding the anti-rejection drug therapy assumption. The study included 74 kidney transplant recipients. RESULTS Individuals with a higher level of education and more years since transplantation showed better mental balance. Regarding gender, women appeared to be less adherent to therapy. Further, the years since transplantation adversely affected the proper pharmacological assumption. Adherence to therapy did not significantly change with the mental health index. CONCLUSION The biopsychosocial illness model provides a conceptualframe of reference in which biological, psychological, and social aspects take on the same importance in the adherence to treatment protocols. For effective management, it is necessary to understand the patients' personal experiences, their assumptions about the disease, health status perception, and mood, and to identify any "barriers" that could cause them to become noncompliant.展开更多
