Impact of COVID-19 Pandemic in Children with CKD or Immunosuppression
2021
Infections are a major concern in children on KRT and with CKD. Risk factors include immunosuppression, multiple contacts in dialysis units, and hospital visits ([1][1]). Italy was one of the countries most affected by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreak ([2][2
Kidney donors and kidney transplants have abnormal aminothiol redox status, and are at increased risk of oxidative stress and reduced redox buffer ca…
2013
Abstract Objective Living kidney donors have been part of a successful kidney transplant programme in Norway for almost 50 years. Glomerular filtration rates (GFRs) have tended to remain stable at about 70% of pre-donation levels. Plasma total homocysteine (Hcy) has an inverse relationship to kidney function, and previous reports indicate elevated levels of Hcy in kidney donors. We wanted to examine the most important plasma aminothiols in kidney donors, i.e. Hcy, cysteine (Cys) and cysteinylglycine (CG) with their redox species. The aminothiol redox-system appears to be an integral part of the extracellular antioxidant defence system in the body. Design and methods Plasma concentrations of…
Detection of a Dissecting Aortic Aneurysm by Renal Transplant Imaging
1997
After 2 years with a normal post-transplant course a 45-year-old man showed an elevated creatinine level (4.5 mg/dL). Transplantation had been neccessary because of progressive glomerulonephritis. Renal transplant imaging was obtained with 150 Mbq Tc-99m MAG3. The perfusion images showed radionuclide accumulation in the area of the upper abdominal aorta and delayed perfusion of the right iliac artery. Accumulation of Tc-99m MAG3 in the transplant was slow and no filling of the bladder could be observed. Immediately after imaging, the patient developed acute hemorrhagic shock. At emergency surgery, a long dissecting and ruptured aneurysm of the abdominal aorta was seen causing delayed and re…
Continuous Normothermic Ex Vivo Kidney Perfusion Is Superior to Brief Normothermic Perfusion Following Static Cold Storage in Donation After Circulat…
2016
Hypothermic preservation is known to cause renal graft injury, especially in donation after circulatory death (DCD) kidney transplantation. We investigated the impact of cold storage (SCS) versus short periods of normothermic ex vivo kidney perfusion (NEVKP) after SCS versus prolonged, continuous NEVKP with near avoidance of SCS on kidney function after transplantation. Following 30 min of warm ischemia, kidneys were removed from 30-kg Yorkshire pigs and preserved for 16 h with (A) 16 h SCS, (B) 15 h SCS + 1 h NEVKP, (C) 8 h SCS + 8 h NEVKP, and (D) 16 h NEVKP. After contralateral kidney resection, grafts were autotransplanted and pigs followed up for 8 days. Perfusate injury markers such a…
Organ recipients suffering from undifferentiated neuroendocrine small-cell carcinoma of donor origin: a case report.
2009
Abstract Background Transmission of donor-derived cancer by organ transplantation is rare, but the risk has been increasing due to the aging donor pool. Undifferentiated neuroendocrine small-cell carcinoma is an agressive tumor with the tendency to spread. Herein we have demonstrated different approaches to treat organ recipients with transmitted tumors. Methods and Results Grafts were retrieved from a decreased donor without any history of previous diseases. Autopsy was not performed after donation. The recipient of the liver graft presented with suspected nodules on routine abdominal ultrasound. After computed tomography (CT) scan, biopsy confirmed the diagnosis of a small-cell carcinoma.…
Management of Kidney Transplantation in a Factor VII-Deficient Patient: Case Report
2012
Transplantation in patients with congenital bleeding disorders is a challenge requiring an integrated approach of various specialists. Renal transplantation, the most frequent type of solid organ transplantation, is rarely performed in individuals with congenital hemorrhagic disorders. We performed a renal transplantation in a 53-year-old man with end-stage renal disease and congenital coagulation factor VII deficiency, a rare bleeding disorder with a peculiar clinical picture requiring replacement therapy in surgical interventions. Perioperative bleeding was successfully prevented by administration of recombinant activated factor VII. Treatment schedule, administration rate, and long-term …
Successful treatment of gastrointestinal bleeding with recombinant factor VIIa after kidney transplantation in patients with pancytopenia.
2006
Abstract Hemostatic disorders can often complicate transplantation procedures. Moreover, antihemmorhagic drugs may not efficiently control bleeding that occurs in such cases. We report on a patient who underwent kidney transplantation complicated by bone marrow aplasia and gastric bleeding who was succesfully treated with recombinant activated FVII (Novoseven). In May 2005, a 53-year-old man affected by chronic renal insufficiency underwent kidney transplantation. At the beginning of June, laboratory tests showed progressive reduction in the blood cell count with anemia, granulocytopenia, and thrombocytopenia related to the development of marrow insufficiency. We commenced transfusion thera…
Use of Intraperitoneal ePTFE Gore Dual-Mesh Plus in a Giant Incisional Hernia After Kidney Transplantation: A Case Report
2009
We evaluated the incidence of and predisposing factors for an incisional hernia after kidney transplantation. Numerous techniques have been used to repair postoperative fascial dehiscences or simple incisional hernias, but no clear treatment exists for giant hernias. Our aim was to obtain (1) a safe procedure to repair a large abdominal defect and reinforce the surrounding, fragile zones and (2) a simple, rapid technique to reduce the operative time. Herein we have described the surgical repair of a giant incisional hernia using intraperitoneal Gore ePTFE dual-mesh plus (Gore-Tex; W. L. Gore, Flagstaff, Ariz, USA) in a 55-year-old man status-post renal transplantation. Total necrosis of dis…
Laparoscopic Repair of Boundary Incisional Hernia in a Kidney Transplant Patient: A Safe Tacks-Fibrin Glue Combined Mesh Fixation Technique.
2018
Abstract Background Incisional hernia in renal transplant patients is a complication that negatively affects the global outcome of transplant and quality of life. The repair of this condition was classically made by open repair with mesh. Increasing evidence suggests that laparoscopic repair could be advocated as the technique of choice in these patients with optimal results. However, the fixation of mesh should be performed by a mixed combination of fibrin sealant (lateral margin of wall defect) and tacks (medial margin). The tacks fixation of the mesh along the lateral margin of the wall defect, close to the graft, is generally difficult for the small size of the remaining aponeurotic pla…
Detection of Human Papillomavirus in Nonmelanoma Skin Cancer Lesions and Healthy Perilesional Skin in Kidney Transplant Recipients and Immunocompeten…
2013
Abstract Background The influence of human papillomavirus (HPV) on the development of nonmelanoma skin cancer (NMSC) is a topic of debate. HPV types from the beta genus (HPV-β) have been most frequently associated with the development of skin cancer. Objectives To analyze the prevalence and range of HPV types in NMSC lesions and healthy perilesional skin in immunodepressed and immunocompetent patients and to evaluate the influence of various clinical factors on the prevalence of HPV in skin cancer. Methods Nested polymerase chain reaction and sequencing were used to detect HPV in 120 NMSC samples obtained by biopsy from 30 kidney transplant recipients and 30 immunocompetent patients. In all…
