Renal artery infectious (mycotic) pseudoaneurysms in renal transplantation recipients. Actas Urol Esp 2021; 45:335-344. [PMID: 34088432 DOI: 10.1016/j.acuroe.2021.04.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2020] [Accepted: 09/22/2020] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Infection of the artery at or around the anastomotic site is an ominous complication commonly presenting as a leak and/or local dissolution of the arterial wall. MATERIAL AND METHODS Narrative review based on relevant PubMed, EMBASE, and Scielo indexed English or Spanish-written articles for the period January 2000-December 2019. A pooled analysis regarding etiology was performed. Based on the results obtained with this approach, a diagnostic/therapeutic algorithm is suggested in order to optimize its clinical management. FINDINGS Arterial pseudoaneurysms are pseudocapsuled contained hematomas generated as the result of an arterial leaking. They are infrequent (<1% of cases), mostly related with infection (contamination of preservation fluid or sepsis) and located at the arterial anastomotic site in renal transplantation recipients. Although they are frequently diagnosed in symptomatic patients days/weeks after transplantation, they may remain unnoticed for long periods being diagnosed incidentally. Color coded-Doppler ultrasound confirms the clinical suspicion. Angio CT-scan and angiography are used for surgical planning or endovascular treatment, respectively. The etiological diagnosis is made on a basis of excised tissue culture. The decision-making process regarding the treatment approach, mostly relies on clinical presentation and anatomical location. Therapeutic options include ultrasound-guided percutaneous thrombin injection, endovascular treatment, and surgery. CONCLUSIONS Mycotic pseudoaneurysms in renal transplantation recipients may pose a significant challenge in cases of spontaneous rupture, given the risk for massive bleeding and death. Adequate management requires accurate diagnosis. Early endovascular stenting remains the treatment of choice in hemodynamically unstable patients. Percutaneous injection and vascular reconstruction present variable success rates in preserving graft function.

Perioperative antibiotic prophylaxis in renal transplantation: a single-center comparison between two regimens and a brief survey among the Eurotransplant renal transplantation centers. World J Urol 2018; 37:957-967. [PMID: 30109484 DOI: 10.1007/s00345-018-2440-2] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2018] [Accepted: 08/07/2018] [Indexed: 10/28/2022] Open
Abstract
BACKGROUND Perioperative antibiotic prophylaxis (PAP) is an integral part of kidney transplantation to prevent surgical site infections (SSI). In July 2015, we changed our standard from a multiple-dose to a single-dose (SD) prophylaxis. Here, we report on results with both regimens and a related survey among Eurotransplant renal transplantation centers. METHODS From July 2015, all kidney graft recipients of our center were scheduled to receive SD i.v. cefazolin (group SD, n = 107). They were compared to patients, transplanted since January 2014, receiving our previous standard (i.v. piperacillin/flucloxacillin) until postoperative day (POD) 7, plus oral sultamicillin until POD 10 (group MD, n = 105). The primary endpoint was the number of SSIs during a 3-month observational period. RESULTS The frequency of SSI episodes was generally low (group SD vs. MD: 2 vs. 4, p = 0.40). Of note, urinary tract infections occurred in 40 SD vs. 36 MD patients, respectively (p = 0.60). Urinary tract infections were caused by Escherichia coli in 36.8%. Female gender was the only independent risk factor on multivariate analysis (p = 0.002). In addition, 12 episodes of urosepsis in both groups occurred. All-cause infection with multi-resistant bacteria occurred less frequently in SD vs. MD patients (3.7% vs. 8.6%, p = 0.16). A majority of Eurotransplant centers used i.v. single-dose cephalosporins (36.9%), although substances and duration varied remarkably. CONCLUSION Single-dose cefazolin was equally effective and less expensive compared to our previous MD regimen. Based on these findings, we conclude that future prospective studies should be designed to confirm the non-inferiority of single-dose antibiotic regimens.

Abstract
Fungal arteritis affecting graft arteries is a rare but life-threatening complication in kidney transplantation (KT). Here, we report the case of a patient with Aspergillus arteritis who experienced renal artery rupture 8 days after KT. We also reviewed 50 other reported cases of fungal arteritis after KT. We found that fungal contamination can occur during kidney graft harvest, preservation, and/or transplantation. Typically, early diagnosis, timely antifungal treatment, and emergency surgery seem crucial for avoiding life-threatening vascular complications.

Abstract
Multi-organ procurement is a risk factor for contamination of preservation fluid with intestinal flora including fungi (e.g., Candida). Transmission of fungal species to the graft vessel can cause mycotic arteritis. This is a very rare but life-threatening complication of renal transplantation. We present 2 cases of renal transplant recipients from the same multi-organ donor. Both recipients suffered from severe hemorrhages from renal graft anastomosis and renal artery pseudoaneurysm due to Candida albicans arteritis (CAA). The culture of the preservation fluid revealed growth of Escherichia coli, but neither preservation fluid nor multiple routine blood cultures performed before hemorrhagic complications revealed fungal growth (media non-selective for fungal growth were applied). The first recipient suffered from sudden severe hemorrhage in the area of graft anastomosis on day 10 post surgery (without any preceding clinical or radiological symptoms). This led to urgent surgery and graftectomy, which was complicated by cardio-respiratory arrest with resuscitation in the operating room; despite resuscitation, irreversible brain damage, and subsequent death occurred in the intensive care unit (ICU) 2 weeks later (on day 24 after transplantation). The second patient underwent urgent vascular surgery on day 22 (after transplantation), because of hemorrhage from a pseudoaneurysm of the graft artery. She required repeated vascular operations, extended antimicrobial and antifungal therapy, and ICU monitoring and, despite these interventions, she died on day 80 after transplantation as a result of Pseudomonas aeruginosa sepsis. Arteritis of the renal artery in both patients was caused by C. albicans. This was confirmed by histopathology: infiltration of renal artery with budding yeast forming pseudohyphae (Case 1), and the presence of C. albicans in the culture of the renal artery and surrounding tissue (Case 2). We conclude that organ preservation solution should be cultured with use of media selective for fungal growth. As soon as the positive culture is detected, appropriate measures protecting patients against CAA should be undertaken.

Abstract
Infections remain a major cause of morbidity and mortality in transplant patients. Organ recipients are also susceptible to donor-derived pathogens and the majority of donor infections are easily treatable. Rarely, some pathogens have produced life-threatening complications by compromising the vascular anastomosis. In this case series we report loss of two kidney allografts secondary to vascular complications due to Candida albicans. Both recipients received grafts from a common donor, in whom Candida bacteremia in the donor was not apparent at the time of organ acceptance but became apparent on delayed cultures.

Abstract
This is a case report of a ruptured vascular anastomosis resulting from fungal arteritis in a commercial renal transplantation. The diagnosis was made quite early posttransplantation (at the 18th posttransplant day); this was proved by histopathologic examination and culture of the vessel wall,which showed Trichosporon fungal infection. The patient underwent operation for control of the bleeding and removal of the graft and of the diseased iliac vascular segment. On reviewing the literature, we found 17 reports of fungal arteritis in solid-organ transplant recipients; our case was the first one to report Trichosporon species as the causative agent. Infection could result from surgical or graft contamination or from preexistent infection in the patient. There is a consensus that the standard of care should include removal of the graft and the diseased iliac vascular segment with an appropriate vascular graft, because simple suturing of the disrupted infected anastomosis generally ends with disastrous recurrent rupture. A high index of suspicion is required to ensure both early diagnosis and appropriate treatment to prevent tragic loss of recipient life.

Abstract
BACKGROUND Infections of renal grafts with Candida species can induce life-threatening complications in the recipient. METHODS A 9-year retrospective study involving all of the transplant centers in France was designed to determine the incidence, origin, characteristics, and outcome of graft-site candidiasis that occurred after kidney transplantation. Yeasts cultured from preservation or drainage solutions and graft specimens were recorded. RESULTS Among 18,617 kidney grafts, 18 recipients corresponding to 12 donors developed culture-confirmed graft-site candidiasis (incidence, 1 case per 1000 grafts) a median of 25 days after the graft procedure. Clinical presentations included 14 cases of renal arteritis (13 were complicated by aneurysm), 1 urinoma, 2 graft site abscesses, and 1 surgical site infection. Candida albicans was involved in 13 cases. A unique C. albicans genotype or a single rare Candida species was involved in each episode. Together with the clinical history, these findings demonstrate that organ contamination followed by transmission to the recipient occurred during recovery. Therapeutic management varied from simple monitoring in 1 case to a combination of surgery (nephrectomy in 9 cases and arterial bypass in 9 cases) and antifungal therapy (14 cases). Overall, 3 of 18 kidney transplant recipients died, and 9 had their graft surgically removed. CONCLUSION Graft-transmitted candidiasis that ends most often in fungal arteritis is associated with high morbidity and mortality after kidney transplantation and is related to organ contamination during recovery in the donor.

Abstract
The complications of kidney graft preservation fluid infected by Candida sp. may range in severity from trivial infections to life-threatening complications, including graft arteritis and anastomotic rupture. Mandatory nephrectomy has recently been proposed as a means of preventing arterial wall rupture in such cases. We describe the clinical features and outcome of renal transplantation from a cadaveric donor in eight recipients with preservation fluid testing positive for Candida sp. Six patients were treated with antifungal drugs. After 1-2 years of follow-up, including regular imaging, none of the patients had developed arterial aneurysm, and all had a functional allograft and were alive. The contamination of renal graft preservation fluid with Candida sp. may be uneventful and should not systematically lead to removal of the graft. Until other risk factors for vascular complications have been determined, early antifungal treatment and repeated radiological monitoring are advisable for the prevention and/or early detection of such complications.

Abstract
BACKGROUND Mycotic arteritis and/or aneurysms are infrequent complications of renal transplantation. They are mostly secondary to bacterial infection and rarely to Candida albicans. We report four cases of mycotic arteritis due to C. albicans after renal transplantation but which have been inoculated during organ harvesting or conservation. METHODS In all the four cases corresponding to two independent donors, C. albicans was isolated few days later in the systematic culture of the conservative liquid. We also review the clinical features and outcomes of 13 cases previously reported in the literature. RESULTS In two cases, the diagnosis of fungal arteritis was confirmed only during autopsy after the patient's death due to massive bleeding. In the other two cases, the diagnosis was made on the arterial section of the anastomotic wall after detransplantation for massive bleeding for arterial leakage although an immediate antifungal treatment with fluconazole and caspofungin was given and was found to be inefficient. CONCLUSION This is a serious complication of renal transplantation because it leads to graft loss in the majority of the cases and even to death in a few cases despite an efficient and rapid treatment. Routine fungal cultures of preservation media are important for early diagnosis and timely surgical interventions are life-saving.

Abstract
INTRODUCTION Candida arteritis can compromise the functional prognosis of the graft or even the life of the transplant recipient. The infection can be transmitted by the graft. OBSERVATION A 46 year-old woman contracted a Candida albicans ateritis of the graft following a kidney transplant that led to a detransplantation. The yeast was probably transmitted by the graft from the donor, source of an unknown candida infection: it was found in the conservation liquid of the graft itself, and in the renal artery and vascular pedicle. Analysis of of these three elements by enzymatic electrophoresis showed that they were identical. COMMENTARIES This case report underlines the need to establish guidelines and sanitary safety measures, notably that of systematically placing in culture the concervation solutions and alerting the transplant team if any fungi are isolated.

Herein, we report 2 cases of rapidly fatal, disseminated coccidioidomycosis that occurred in organ transplant recipients who had never lived in or visited an area where C. immitis is endemic. Both subjects had received a transplanted organ from the same donor, an individual with unrecognized active coccidioidomycosis at the time of his death.

Abstract
Fungi cause 8% of nosocomial infections. This is caused, in part, by the increasing pool of immunocompromised patients. Elderly, transplant and HIV patients, as well as premature infants, have become prime candidates for invasive fungal infections. The widespread use of broad spectrum antibiotics plays a role. Utilisation of appropriate antifungal treatment modalities requires an understanding of the pathogenesis of infection. This is a challenging problem as fungi can cause different clinical manifestations that depend on the type of fungal species and patient response to the infection. Although Candida spp. are the most frequent pathogen, other species such as Aspergillus and Cryptococcus have become major pathogens. Environmental fungi which include Blastomyces, Coccidioides and Histoplasma have become more aggressive in the vulnerable patient. The genitourinary system can be a source or target of disseminated fungal infection. Diagnosis depends on clinical awareness, utilisation of appropriate diagnostic modalities, imaging modalities and a thorough clinical assessment. The treatment of primary (Blastomyces, Coccidioides, Histoplasma) infection generally requires amphotericin B (AmpB). The opportunistic infections (Aspergillus, Cryptococcus and Candida) may respond to the triazoles although AmpB remains the 'gold standard'. Infections caused by Candida spp. represents the greatest challenge to the clinician. The presence of Candida spp. in the urine may indicate colonisation or infection. Untreated, Candida can remain as a 'saprophyte' or develop ascending infection, sepsis or death. The prophylactic use of fluconazole may in itself result in resistant infection, hence the 'conundrum'.
