Purpose: The trabecular meshwork (TM) is involved in the outflow of aqueous humor and intraocular pressure (IOP) regulation. Regulation of the extracellular matrix (ECM) by TGFβ2 signaling pathways in the TM has been extensively studied. Recent evidence has implicated toll-like receptor 4 (TLR4) in the regulation of ECM and fibrogenesis in liver, kidney, lung, and skin. Here, we investigated the role of TGFβ2-TLR4 signaling crosstalk in the regulation of the ECM in the TM and ocular hypertension...

BACKGROUND: The Organ Procurement Network recommends a surgeon record 15 cases as surgeon or assistant for laparoscopic donor nephrectomies (LDN) prior to independent practice. The literature suggests that the learning curve for improved perioperative and patient outcomes is closer to 35 cases. In this article, we describe our development of a model utilizing fresh tissue and objective, quantifiable endpoints to document surgical progress and efficiency in each of the major steps involved in LDN...

Compatible pairs of living kidney donors and their intended recipients can enter into kidney paired donation (KPD) and facilitate additional living donor kidney transplants (LDKTs). We examined 11 compatible pairs (the intended recipients and their intended, compatible donors) who participated in KPD, along with the recipients' 11 matched, exchange donors. The 11 pairs participated in 10 separate exchanges (3 were multi-center exchanges) that included 33 total LDKTs (22 additional LDKTs). All the intended donors were blood group O and female, with a mean living kidney donor profile index (LKDPI) of 27...

INTRODUCTION: Laparoscopic donor nephrectomy is widely used to retrieve a kidney for transplantation. Preoperative evaluation of the donor is of crucial importance to the recipient. In particular, vascular anatomy should be assessed with the help of modern imaging modalities. We present a hand-assisted laparoscopic nephrectomy of a kidney donor with a complete duplex vena cava. CASE REPORT: A 40-year-old male patient was admitted to our clinic as a kidney donor for his 20-year-old son...

INTRODUCTION: Living donor liver transplantation (LDLT) is performed with increasing frequency worldwide due to the shortage of donated organs. It is a life-saving procedure for the recipient, but, on the other hand, a major surgical procedure for healthy donors and it may cause morbidity and even mortality. PATIENTS AND METHODS: This research was completed at Dokuz Eylül University Faculty of Medicine Hospital General Surgery Department Liver Transplant Unit and included 280 cases (4 with simultaneous liver and kidney transplants from living donors) who underwent donor right hepatectomy for LDLT from June 2000 to June 2016...

BACKGROUND: Depending on hyphothalamic, hyphophyseal, and gonadal axis dysfunction, anovulatory irregular cycles occur and the probability of pregnancy decreases in the patients with chronic kidney disease (CKD). Maternal mortality and morbidity rates are increased in CKD patients; the risk of premature delivery is 70% and the risk of preeclampsia is 40% more than normal among those with a creatine level of >2.5 mg/dL. METHODS: If a pregnancy is expected in the sequel of kidney transplantation (KT), a multidisciplinary team approach should be adopted and both the gynecologist and the nephrologist should follow the patient simultaneously...

BACKGROUND: Anti-T-lymphocyte globulins (ATG) are most commonly used as induction agents in kidney transplantation (KT). In this study, we investigated the use of ATG as induction therapy in deceased-donor KT. METHODS: Among 152 deceased-donor KT recipients transplanted between January 2009 and December 2003, 147 with exact data were enrolled in this study. Delayed graft function was defined as dialysis requirement after KT. Greater than 10% panel-reactive antibody (PRA) was considered as positive...

BACKGROUND: Induction therapy is mostly recommended for deceased-donor transplantation, whereas it has some controversies in live-donor transplantation. In this study, we described the outcomes of live-donor renal transplant recipients who received ATG-Fresenius (ATG-F) induction. METHODS: Live-donor transplantations in patients over 18 years old with ATG-F induction between 2009 and 2015 were included. All patients received quadruple immunosuppression, one of which was ATG-F induction...

INTRODUCTION: The crossmatch test is essential prior to kidney transplantation (tx) to confirm compatibility between the donor and the recipient. However, its results can be misleading due to "undetectable antibodies" in the recipient's serum. To establish if undetectable autoantibodies are responsible for a positive result, an auto-crossmatch test can be performed. In this study, we aim to determine the long-term prognostic value of auto-flow cytometric auto-crossmatch (FCXM) test on kidney survival in kidney tx recipients...

BACKGROUND: Kidney transplantation is the best treatment method for end-stage renal disease. Technically, left kidney transplantation is easier than right kidney, and the complication rates in the right are higher than the left kidney. We performed 28 kidney transplantations from 14 deceased donors between November 2010 and May 2016. Our aim was to share our outcomes and experiences about these 28 patients. METHODS: We performed 182 kidney transplantations between November 2010 and May 2016...

INTRODUCTION: High rates of panel-reactive antibody (PRA) may decrease the chance of kidney transplantation and may result in long waiting periods before transplantation. The calculated PRA (cPRA) is performed based on unacceptable HLA antigens. These antigens are identified by a program that was created based on the antibodies that developed against the HLA antigens circulating in serum and on the risk of binding of these antibodies to antigens. The antigen profile of the population and antigen frequencies can be measured, and more realistic cPRA positivity rates may be obtained using this method...

Viral infections lead to significant morbidity and mortality in kidney transplant recipients. We evaluated 49 kidney transplant recipients for human herpesvirus 8 (HHV-8) and BK polyomavirus infections in conjunction with data obtained from 43 donors. The seroprevalence of HHV-8 was 6.9% in donors and 12.2% in recipients. HHV-8 DNA was detected below the limit of quantification (<5000 copies/mL) in a recipient with HHV-8 seropositivity at the pretransplant period and was undetectable at month 3 after transplantation...

BACKGROUND: Ureteral stent insertion during kidney transplantation is a matter of debate. Stenting has been proven to reduce the risk of surgical complications. In addition, it has been reported to increase risks such as urinary tract infections especially after operation. Ureteral stent colonization (USC) is known to play a role in the pathogenesis of stent related-infections. The aim of this study was (1) to assess the frequency of USC and values of urine cultures in identifying colonizing bacteria; (2) to assess the importance of indwelling time for USC in live-donor renal transplant recipients; and (3) to evaluate the biomarker role of neutrophil-to-lymphocyte ratio (NLR) on USC...

BACKGROUND: Substantial attention has recently been paid to the possibility of an increased risk of chronic kidney disease (CKD) in living kidney donors. It has been demonstrated that CKD patients suffer from increased oxidative stress, which have been reported to show a strong association with several clinical problems such as accelerated atherosclerosis. The purpose of the current cross-sectional, single-center study was to evaluate the relationship between renal functions of living kidney donors and systemic oxidative stress...

INTRODUCTION: Because of the shortage of organs available for transplantation, living related sequential transplantation with the use of liver and a kidney from the same donor has emerged as a reasonable therapeutic alternative. However, there is insufficient literature about the complications that living donors experience after simultaneous kidney and liver transplantations. METHODS: From December 2001 to October 2009, 5 living donors provided simultaneous donation of livers and kidneys and 1 living donor donated first her kidney and then her liver...

BACKGROUND: Familial Mediterranean fever (FMF) is an autosomal-recessive autoinflammatory disorder manifested severely by systemic amyloidosis. It has been hypothesized that heterozygous carriers may also have susceptibility to certain symptoms or even diseases. Because the living kidney donors of patients with FMF are generally relatives of the kidney recipients, there is a high possibility that the donors will have a heterozygous mutation of the FMF gene. The goal of this study was to investigate the long-term kidney function of donors who are carriers of the Mediterranean fever (MEFV) gene...
