Insufficient is the evidence for safe use of elderly donors in adult-to-adult living donor liver transplantation (LDLT). The aim of this study was to evaluate the outcomes of right lobe LDLT by donor age (≥55 vs. <55 years). All living donors who underwent right hepatectomy at the authors' institution between March 2008 and December 2015 were divided into 2 groups: group A with an age ≥ 55 and group B with an age < 55. The selection criteria for elderly donor were preservation of middle hepatic vein, remnant liver volume ≥30%, and no or mild fatty liver...

Lenalidomide is an immunomodulatory drug administered orally in the treatment of multiple myeloma. Some elderly patients require a reduced lenalidomide dose because of comorbidities and/or adverse events. This study investigated the actual dose of lenalidomide in elderly patients, finding that most received reduced (5-10 mg) doses. The most common reasons for dose reduction were renal dysfunction (54% of patients), fatigue (grade ≥3; 20%), hematologic disorder (grade ≥3; 14%), and rash (grade ≥3; 9%)...

Post-transplant diabetes mellitus occurs in 30-50% of cases during the first year post-renal transplantation. It is associated with increased morbidity, mortality and healthcare costs. Risk factors include age and specific immunosuppression regimens. At the same time, renal transplantation is increasingly indicated in elderly (aged >65 years) patients as this proportion of older patients in the prevalent dialysis population has increased. The immune system and β cells undergo senescence and this impacts on the risk for developing post-transplant diabetes and our ability to prevent such development...

BACKGROUND: Given the expected increase in the number of elderly recipients, details regarding how clinical factors influence the outcome in living donor liver transplantation (LDLT) for the elderly remain unclear. We examined the survival outcomes according to the results of donor age-based and graft volume-based analyses and assessed the impact of prognostic factors on the survival after LDLT for elderly recipients. METHODS: The 198 adult recipients were classified into 2 groups: an elderly group (n = 70, E group; ≥ 60 years of age) and a younger group (n = 128, Y group; <60 years of age)...

Ever since the first liver transplant in the Republic of Moldova in 2013 we have performed 30 liver transplantations, the first having been performed in collaboration with the surgical team from Romania, led by Professor Irinel Popescu. The serious deficit of available cadaveric organs has forced us to begin with right hemi-liver transplantation from a living donor. In one third of liver transplantations we used right hemi-liver graft from a living donor, and in 2/3 of cases whole liver graft was harvested from brain-dead donors...

Acute myeloid leukaemia (AML) is a malignancy in need of new therapeutic options. The current standard of care chemotherapy, leads to complete remission (CR) in the vast majority of adult patients under the age of 60. In contrast, CR rates in patients over the age of 60 reaches only 40-60%. While achievement of a CR is an important stepping stone in the treatment of AML, the majority of these patients experience relapse and die of their disease without adequate consolidation chemotherapy. Blood and marrow transplantation (BMT) can improve outcome in a select patient with AML but unfortunately, it is not a valid treatment option for the majority of older patients...

Allogeneic stem cell transplantation (allo-SCT) is the only curative option for myelodysplastic syndrome (MDS) and acute myeloid leukemia (AML). Azacitidine (AZA) has a good toxicity profile compared with intensive chemotherapy and can be considered a pre-transplant regimen in elderly patients and in patients with comorbidities. To investigate the impact of pre-transplant AZA on patient outcome after allo-SCT, we conducted a retrospective analysis of AZA pre-treatment followed by allo-SCT in patients with high-risk MDS and AML...

Autologous hematopoietic stem cell transplantation (ASCT) is an established treatment for multiple myeloma (MM), yet the impact of transplanted CD34+ cell dose remains unresolved, especially in patients over the age of 65 years. Data was collected from 207 consecutive ASCT patients to determine the relationship between CD34+ infusion count and short-term and long-term platelet recovery. For MM patients under the age of 65 years (n=155), CD34+ dosage correlates with time to platelet engraftment (p<0.001) and platelet count at 30 days (p=0...

Kaposi's sarcoma is associated with immunosuppressant treatment administered to patients with organ transplant and other immune related disorders. Several case reports have reported association of Kaposi's sarcoma and steroids. Almost all patients in those case reports had localised disease to skin and they responded to tapering doses or discontinuation of steroids. Here we present a case of an elderly asthmatic man who was using self-medication with systemic and inhaled steroids for about two decades. He presented with widespread skin lesions and anemia...

Acute lymphoblastic leukemia (ALL) is the second most common acute leukemia in adults, with an incidence of over 6500 cases per year in the United States alone. The hallmark of ALL is chromosomal abnormalities and genetic alterations involved in differentiation and proliferation of lymphoid precursor cells. In adults, 75% of cases develop from precursors of the B-cell lineage, with the remainder of cases consisting of malignant T-cell precursors. Traditionally, risk stratification has been based on clinical factors such age, white blood cell count and response to chemotherapy; however, the identification of recurrent genetic alterations has helped refine individual prognosis and guide management...

BACKGROUND/AIMS: Although multiple myeloma (MM) is typically a disease of the elderly, a certain subset of extremely young patients exists. It is necessary to establish clinicopathological characteristics for this population. METHODS: We reviewed the medical records of MM patients whose age was 40 years or younger at diagnosis. RESULTS: A total of 32 patients were analyzed (male to female ratio 19:13, median age 37 years). According to International Staging System, 29%, 48%, and 16% were in stage I, II, and III, respectively...

Unrelated cord blood transplantation (UCBT) after a reduced intensity conditioning regimen (RIC) has extended the use of UCB in elderly patients and those with co-morbidities without an HLA-identical donor, although post-transplant relapse remains a concern in high-risk acute myeloid leukemia (AML) patients. HLA incompatibilities between donor and recipient might enhance the alloreactivity of natural killer (NK) cells after allogeneic hematopoietic stem-cell transplantation (HSCT). We studied the reconstitution of NK cells and KIR-L mismatch in 54 patients who underwent a RIC-UCBT for AML in CR in a prospective phase II clinical trial...

Approximately 50% of individuals aged 6-49 years in the United States are infected with cytomegalovirus (CMV), with seroprevalence increasing with age, reaching 85-90% by 75-80 years according to Bate et al. (Clin Infect Dis 50 (11): 1439-1447, 2010) and Pawelec et al. (Curr Opin Immunol 24:507-511, 2012). Following primary infection, CMV establishes lifelong latency with periodic reactivation. Immunocompetent hosts experience largely asymptomatic infection, but CMV can cause serious illness in immunocompromised populations, such as transplant patients and the elderly...

The aging of the on-dialysis population raises the issue of whether to propose elderly patients for kidney transplantation and how to manage their immunosuppression. This study aims to analyze the outcome of kidney transplantation on an Italian series of elderly recipients. We included in this retrospective study all patients over 60 years, receiving a deceased-donor kidney transplantation from January 2004 to December 2014 in two north Italian Centers. We analyzed the correlation of recipient age with graft's and patient's survival, delayed graft function (DGF), acute cellular rejection (ACR), surgical complications, infections and glomerular filtration rate (GFR)...

Age-related macular degeneration (AMD) is a common cause of central visual loss in the elderly. Retinal pigment epithelial (RPE) cell loss occurs early in the course of AMD and RPE cell transplantation holds promise to slow disease progression. We report that subretinal transplantation of RPE stem cell (RPESC)-derived RPE cells (RPESC-RPE) preserved vision in a rat model of RPE cell dysfunction. Importantly, the stage of differentiation that RPESC-RPE acquired prior to transplantation influenced the efficacy of vision rescue...

The process of ageing has an impact on the entire human body including the organ systems. In transplantation, professionals are daily faced with risk assessment of suitable donor offers , whether to accept a liver graft for a specific recipient. In this context, livers from elderly donors are more frequently accepted for transplantation, to increase the donor pool and compensate the high waiting list mortality. In the current practice it is not unusual to accept 60-year old donor livers for transplantation, as the donor demographics have significantly changed over the years...

BACKGROUND: The average ages of lung transplant (LTx) recipients and donors are increasing. With older recipients considered to be especially at high risk of posttransplant mortality, we sought to determine whether the use of allografts from older donors affects survival among older patients undergoing LTx. METHODS: The United Network for Organ Sharing registry was used to identify patients aged 65-80 y receiving a first-time LTx between 1987 and 2013. Survival analysis examined implications of a donor-recipient age difference >10 y using Cox proportional hazards regression...

The chronic shortage of human transplants to treat tissue and organ failure has led to the development of xenotransplantation, the transplantation of cells, tissues and organs from another species to human recipients. For a number of reasons, pigs are best suited as donor animals. Successful, routine xenotransplantation would have an enormous impact on the health of the human population, including the young, who sometimes require a replacement organ or islet cells, but especially the elderly, who more often suffer the consequences of organ failure...
