A case report of a difficult dissection of the iliac vessels conducted by means of the harmonic scalpel during a kidney transplantation
2011
Background. The “difficult” preparation of iliac vessels in the kidney transplant recipient caused by a perivascular fibrosis with satellite lymphadenopathy is sometimes burdened by post-transplant complications (lymphocele, seroma and hematoma). Both iliac vascular adhesions and satellite lymphoadenopaty are often due to reiterate femoral cannulation aimed to hemodialysis. Patients and Methods: The case report concerns a 60 years old female uremic patient, on dialysis for about 4 years with perivascular fibrosis and pelvic lymphadenopathy caused by bilateral femoral artery catheterization. In the course of kidney transplant, preparation of the iliac vessels was performed by ultrasonic scal…
Organ Recovery Procedure in Donation After Controlled Circulatory Death with Normothermic Regional Perfusion: State of the Art
2020
The global shortage of organ donors will not be resolved solely by relying on donation after brain death. Expansion to use of donation after controlled circulatory death will be needed to address the shortfall of organs for transplantation. The processes of warm ischemia threaten the viability of organs obtained after controlled circulatory death, but these can be minimized by well-organized donation pathways and new techniques of in situ organ preservation, such as normothermic regional perfusion. The use of extracorporeal membrane oxygenation (ECMO) devices for normothermic regional perfusion in liver transplantation can help reduce rates of biliary complications, ischemic type biliary le…
SUCCESFULLY TREATED HEMOLITIC UREMIC SYNDROME (HUS) BY PLASMA APHERESIS AFTER KIDNEY TRANSPLANTATION
2009
Objectives: The HUS is a rare disease; it exists a kind related to acute toxicity by Cyclosporine on the short time following kidney transplantation. Although the causes of this syndrome are still unclear, data from the literature show that patients with high levels of Reactive Antibodies (PRA test), Alport syndrome (as primitive renal disease), or which have history of HUS present a higher risk of HUS after renal transplantation. Materials and Methods: We report a case of a 58 yr old woman whose cause of uremia we did not know dependent on an episode of HUS. The patients underwent renal transplantation from deceased donor and treated with Cyclosporine, Mycophenolate Mofetil and steroids as…
Shedding light on the elusive role of endothelial cells in cytomegalovirus dissemination.
2011
Cytomegalovirus (CMV) is frequently transmitted by solid organ transplantation and is associated with graft failure. By forming the boundary between circulation and organ parenchyma, endothelial cells (EC) are suited for bidirectional virus spread from and to the transplant. We applied Cre/loxP-mediated green-fluorescence-tagging of EC-derived murine CMV (MCMV) to quantify the role of infected EC in transplantation-associated CMV dissemination in the mouse model. Both EC- and non-EC-derived virus originating from infected Tie2-cre + heart and kidney transplants were readily transmitted to MCMV-naïve recipients by primary viremia. In contrast, when a Tie2-cre + transplant was infected by pri…
Human cytomegalovirus glycoprotein B genotypes in immunocompetent, immunocompromised, and congenitally infected Italian populations
2003
Human cytomegalovirus (HCMV) strains, obtained from immunocompetent and immunocompromised Italian hosts, were typed with glycoprotein B (gB) gene restriction analysis. A predominant circulation of HCMV strains with gB type 2 and 3 was detected in both the immunocompetent host with a primary HCMV infection and the immunocompromised host with or without HCMV disease. No association between gB types and subjects with different risks of developing HCMV disease was found. All four gB genotypes were capable of causing congenital infection in Italian babies, with gB type 1 accounting for 50% of the strains examined in symptomatic infants and a remarkable incidence of gB type 4 viruses.
Effectiveness of substituting cyclosporin A with tacrolimus in reducing gingival overgrowth in renal transplant patients
2009
Objectives: this study aims to evaluate the effectiveness of periodontal therapy combined with tacrolimus in the suppression of gingival overgrowth (GO) and the effect on GO of changing from cyclosporin A to tacrolimus. Patients and methods: sixteen renal transplant patients, averaging 52 years of age, whose kidney function was stable and were receiving treatment with cyclosporin A, were randomly assigned to one of two groups. In the experimental group, patients were instructed in oral hygiene and underwent periodontal treatment, whereas in the control group, only oral hygiene instructions were given. After the first visit and the change of medication from cyclosporine to tacrolimus in both…
Renal malakoplakia as a pseudotumoral lesion in a renal transplant patient: A case report
2007
Malakoplakia is a rare chronic inflammatory disease associated with gram-negative bacterial infections frequently caused by Escherichia coli. Malakoplakia usually affects the lower urinary tract (bladder) but there are cases described in the kidney as well as in the respiratory and digestive organs. We report on a case with renal parenchymal malakoplakia in a renal transplant patient and describe the pathological lesions of malakoplakia: histiocytic proliferation with scarce inflammatory infiltrate, histiocytes with acidophilic cytoplasm and the presence of characteristic Michaelis-Gutmann bodies. The authors in this study review the updated reports related to the entity in this uncommon lo…
Renal Transplantation by Automatic Anastomotic Device in a Porcine Model
2015
Automatic vascular staplers for vascular anastomoses in kidney transplantation may dramatically reduce the operative time and, in particular, warm ischemia time, thus increasing the outcome of transplantation. Ten pigs underwent kidney auto-transplantation by automatic anastomotic device. Kidneys were collected by laparotomy with selective ligations at the renal hilum and perfused with cold storage solution. To overcome the shortage in length of renal hilum, a tract of the internal jugular vein was harvested to increase the length of the vessels. The anastomoses were totally performed by the use of the anastomotic device. On 10 kidney transplants, nine were successful and no complications o…
Recurrent leishmaniasis in kidney transplant recipients: Report of 2 cases and systematic review of the literature
2011
The characteristics of 8 episodes of leishmaniasis with atypical manifestations in 2 Italian kidney transplant recipients are analyzed and contextualized among those of 52 other episodes of leishmaniasis observed in 19 transplant recipients found through a systematic review of the international literature. In all the patients, the initial episode was visceral leishmaniasis, which was associated with mucocutaneous involvement in 2 cases. With the exception of 1 case of post kala-azar dermal leishmaniasis, 2 episodes of Leishmania endophthalmitis, and 3 episodes of mucocutaneous leishmaniasis, all the recurrences were characterized by visceral involvement. The potential role of polymerase cha…
Executive summary of the 2018 KDIGO Hepatitis C in CKD Guideline: welcoming advances in evaluation and management
2018
Infection with the hepatitis C virus (HCV) has adverse liver, kidney, and cardiovascular consequences in patients with chronic kidney disease (CKD), including those on dialysis therapy and in those with a kidney transplant. Since the publication of the original Kidney Disease: Improving Global Outcomes (KDIGO) HCV Guideline in 2008, major advances in HCV management, particularly with the advent of direct-acting antiviral therapies, have now made the cure of HCV possible in CKD patients. In addition, diagnostic techniques have evolved to enable the noninvasive diagnosis of liver fibrosis. Therefore, the Work Group undertook a comprehensive review and update of the KDIGO HCV in CKD Guideline.…
