PURPOSE: Transplantation of in vitro cultured limbal epithelial stem cells (LESCs) is a treatment widely used for LESC deficiency. However, the number of limbal tissue donors is limited, and protocols for LESC cultivation often include compounds and/or feeder layers that can induce side effects and/or increase the cost of the culture procedure. We investigated the feasibility of obtaining more than one limbal primary culture (LPC) from the same biopsy using a culture medium in which several potentially harmful compounds were replaced at the same time by biosafe supplements, allowing the LESC cultivation without feeder layers...

Long term use of steroids results in predictable secondary effects that can lead to increased morbidity and mortality. In this study, we present 10 years' worth of data of early steroid withdrawal (ESW) immunosuppression consisting of Mycophenolate, Sirolimus, and Tacrolimus. From 2003 to 2013, 563 kidney transplant recipients were weaned off steroids prior to discharge. We compared outcomes with that of our 65 historical controls maintained on steroids. We analyzed graft and patient survival and determined the incidence of steroid-related comorbidities such as hypertension, hypercholesterolemia, diabetes, coronary artery disease, and weight gain...

AIM: To avoid desensitization protocols and ABO incompatible kidney transplantation (KT) due to high costs and increased risk of infections from intense immunosuppression. METHODS: We present institutional ethical review board - approved study of single center 6-way kidney exchange transplantation. The participants comprised ABO incompatibility (n = 1); positive cross-match and/or presence of donor specific antibody (n = 5). The average time required from registration in kidney paired donation (KPD) registry to find suitable donors was 45 d and time required to perform transplants after legal permission was 2 mo...

Until now, absolute uterine factor infertility has been the major untreatable form of female infertility. Recently, uterus transplantation has proven to be the first successful treatment for absolute uterine factor infertility, with demonstration of live births. Here, live donation uterus transplantation was performed in nine women. 163 cervical biopsies (149 protocol, 14 follow-up) were taken to detect histopathological signs of rejection. Based on experience from animal experiments, we used a three-grade scoring system to evaluate biopsies systematically...

BACKGROUND: Salt and water disturbances often occur during acute kidney allograft dysfunction that contribute to graft failure, but this condition has been poorly investigated in the alloreactivity setting. We evaluated the tissue expression of aquaporins (AQP1 and AQP2) and the epithelial sodium channel (ENAC) in kidney biopsy specimens from sensitized kidney transplant recipients. METHODS: Eighty-six biopsy specimens from 33 sensitized patients were divided into 3 groups according to clinical context: time-zero (n = 9), protocol (n = 9), and indication (n = 68)...

Activated hepatic stellate cells express cytoplasmic ASMA prior to secreting collagen and consequent liver fibrosis. We hypothesized that quantifying ASMA could predict severity of future fibrosis after LT. For this, 32 pairs of protocol biopsies, that is, "baseline" and "follow-up" biopsies taken at 1- to 2-year intervals from 18 stable pediatric LT recipients, transplanted between 2006 and 2012 were selected. Morphometric quantification of "ASMA-positive area percentage" was performed on the baseline biopsy...

BACKGROUND: Lymphangiogenesis occurs in diseased native kidneys and kidney allografts, and correlates with histological injury; however, the clinical significance of lymphatic vessels in kidney allografts is unclear. METHODS: This study retrospectively reviewed 63 kidney transplant patients who underwent protocol biopsies. Lymphatic vessels were identified by immunohistochemical staining for podoplanin, and were classified according to their location as perivascular or interstitial lymphatic vessels...

The chronic dysfunction stands as the most common cause of renal allograft loss. During the nineties of the past century, this condition was referred to as chronic allograft nephropathy (CAN). Since 2005, CAN has been assigned by the eighth Banff schema to four main categories via histopathological and immunohistochemical findings including chronic antibodymediated rejection (CAMR), chronic T-cell-mediated rejection (CTMR), chronic cyclosporine toxicity (CNITOX), and "interstitial fibrosis (IF)/tubular atrophy; not otherwise specified (NOS)" to eliminate the term CAN...

As both T cell and antibody-mediated rejection can have a subclinical phase, protocol biopsies provide an early opportunity to intervene before the onset of clinical allograft dysfunction. Protocol biopsies are usually done after reperfusion to establish baseline, between 3 and 6 months to identify subclinical rejection, and at 6-12 months to assess chronicity and persistent inflammation that have prognostic implication. Treatment of both subclinical T cell and antibody-mediated rejection prevents progression of rejection and development of interstitial fibrosis/tubular atrophy or transplant glomerulopathy...

Patients with limbal stem cell deficiency (LSCD) often experience pain and photophobia due to recurrent epithelial defects and chronic inflammation of the cornea. Successfully restoring a healthy corneal surface in these patients by transplantation of ex vivo expanded human limbal epithelial cells (LECs) may alleviate these symptoms and significantly improve their quality of life. The clinical outcome of transplantation is known to be influenced by the quality of transplanted cells. Presently, several different protocols for cultivation and transplantation of LECs are in use...

BACKGROUND AND AIMS: Thalassemia is curable by bone marrow transplantation; however, finding suitable donors with defined HLA combination remains a major challenge. Cord blood stem cells with preselected HLA system through preimplantation genetic diagnosis (PGD) proved very useful for resolving scarce HLA-matched bone marrow donors. METHODS: A thalassemia trait couple with an affected child was included in this study. We used informative STR markers at the HLA and beta globin loci to develop a single cell multiplex fluorescent PCR protocol...

In brain-dead donor resuscitation, hydroxyethyl starch (HES) use has been associated with presence of osmotic-nephrosis-like lesions in kidney transplant recipients. Our aim was to determine whether the presence of HES in protocol renal graft biopsies at three months (M3) after transplantation is associated with renal graft quality. According to the HES administered to the donor during the procurement procedure, two groups of patients were defined according graft exposition to HES: HES group, (N = 20) and control group (N = 6)...

BACKGROUND Pulmonary alveolar proteinosis (PAP) is a rare condition characterized by the intra-alveolar accumulation of surfactant-derived material, which impairs gas exchange and results in respiratory insufficiency. Two major subtypes of PAP are autoimmune and non-autoimmune PAP. The diagnosis relies on clinical presentation, ground glass opacities on CT scan, bronchoscopy with PAS stain of BAL fluid (BALF), lung biopsy with PAS-positive material in the alveoli, and the presence of anti GM-CSF antibodies in serum or BALF for an autoimmune subtype...

BACKGROUND: Anemia and low-grade inflammation are reported to be associated with impaired long-term graft outcome in renal transplant (RTx) recipients. In this study, hemoglobin (Hb) and inflammation marker levels were correlated with measured glomerular filtration rate (GFR) in 128 pediatric RTx recipients over a median follow-up period of 10 years. METHODS: Serum levels of erythropoietin (EPO), hepcidin-25, high-sensitivity C-reactive protein (CRP) (hsCRP) and interleukin-6 (IL-6) were analyzed by enzyme-linked immunosorbent assays, and GFR was analyzed by (51)Cr-EDTA clearance...

AIM: Optimizing nephron supply to recipient demand is a non-immunologic determinant of renal allograft outcome. Nephron reduction is usually caused by physical donor-recipient mismatch, but its pathologic relevance remains to be determined. METHODS: Thirty-one recipients of living donor renal transplants were divided into three subgroups: those who received transplants from the same gender (n = 6, Group 1) and those who underwent male-to-female (n = 8, Group 2) and female-to-male (n = 17, Group 3) transplants...

INTRODUCTION: The pros and cons for implementing protocol biopsies (PB) after kidney transplantation are still a matter of debate. We aimed to address the frequency of pathological findings in PB, to analyze their impact on long-term graft survival (GS) and to analyze the risk factors predicting an abnormal histology. METHODS: We analyzed 946 kidney PB obtained at a median time of 6.5 (±2.9) months after transplantation. Statistics included comparison between groups, Kaplan-Meier and multinomial logistic regression analysis...

BACKGROUND: Antibody-mediated rejection (ABMR) represents 1 of the cardinal causes of late allograft loss after kidney transplantation and there is great need for noninvasive tools improving early diagnosis of this rejection type. One promising strategy might be the quantification of peripheral blood DNA levels of the highly prevalent and apathogenic Torque Teno virus (TTV), which might mirror the overall level of immunosuppression and thus help determine the risk of alloimmune response...
