Aortic Graft Mycotic Pseudoaneurysm as a Severe Complication After Multivisceral Transplantation: A Case Report.

BACKGROUND: Surgical complications in multivisceral transplantation (MVT) are frequent and always severe. Those related to technical issues are relevant as they have implications not only on the graft but also on patient survival. The aim of this study was to review our case-based data and experience with 5 MVT performed since December 2004. CASE REPORT: A 38 year-old woman presented with ultra-short bowel syndrome due to massive ischemia also affecting the celiac trunk. She also had moderate to severe hepatitis/steatosis with some degree of fibrosis on liver biopsy, due to long-term home parenteral nutrition (HPN). An MVT was carried out in September 2010 including the liver, stomach, pancreatoduodenal complex with the spleen, and small bowel. The postoperative course was complicated by a leak from the pyloromiotomy, requiring reoperation on postoperative day 13. She also had central line catheter infection and renal impairment, requiring renal replacement therapy, and was discharged on postoperative day 150. Fifteen days later she was hospitalized because of severe abdominal pain associated with an abdominal mass. Computed tomography showed an aortic donor graft pseudoaneurysm, so we decided to operate on the patient. A complete resection of the pseudoaneurysm using an interposed polytetrafluoroethylene graft was performed. Six months after the MVT, the patient died due to sepsis, despite a functional graft and complete digestive autonomy. CONCLUSIONS: Although this complication is rare, surgical complications in MVT are severe and may seriously impair graft and patient survival.

Renal failure associated with intestinal transplantation: our experience in Spain.

BACKGROUND: Renal failure (RF) is a frequent complication in non-renal solid organ transplants. In the present study, we analyze our experience with intestinal transplants (ITx). METHODS: Between 2004 and 2012, we performed 21 ITx in 19 adult patients. Alemtuzumab was used as an induction agent followed by tacrolimus. Renal function was assessed before ITx and during the perioperative period. RESULTS: The main cause for transplants was non-resectable desmoids tumors (33.3%), followed by vascular thrombosis (19%) and others. Medical complications were frequent, especially infectious diseases, which were the most common (51%). Surgical complications were also frequent, but most of them (>50%) were mild but leading to a great number of re-operations and prolonged stays in hospital. Acute rejection is very frequent (66.6%) but mild in more than 70% of the cases. Finally, RF was very frequent (68.4%; 13/19 patients) and accounted for 15.6% of all medical complications. Causes were multiple. One patient is awaiting a kidney transplant, but no other patients need renal replacement therapy at the moment. Ileostomy closure was performed in 5 of 12 patients alive, showing improved renal function in 3 of them. CONCLUSIONS: RF is a problem in ITx and is always multifactorial. Increases in hospital stay, higher morbidity and is a cause for hospital readmission. Almost all patients had an impaired renal function when discharged. Immunosuppressants and ileostomy closure as soon as possible might prevent RF.

Porcine acellular dermal matrix for delayed abdominal wall closure after pediatric liver transplantation.

Children are one of the groups with the highest mortality rate on the waiting list for LT. Primary closure of the abdominal wall is often impossible in the pediatric population, due to a size mismatch between a large graft and a small recipient. We present a retrospective cohort study of six pediatric patients, who underwent delayed abdominal wall closure with a biological mesh after LT, and in whom early closure was impossible. A non-cross-linked porcine-derived acellular dermal matrix (Strattice(™) Reconstructive Tissue Matrix; LifeCell Corp, Bridgewater, NJ, USA) was used in all of the cases of the series. After a mean follow-up of 26 months (21-32 months), all patients were asymptomatic, with a functional abdominal wall after physical examination. Non-cross-linked porcine-derived acellular dermal matrix (Strattice(™) ) is a good alternative for delayed abdominal wall closure after pediatric LT. Randomized controlled trials are necessary to determine the best moment and the best technique for abdominal wall closure.

Disseminated nocardiosis: a rare infectious complication following non-heart-beating donor liver transplantation.

Nocardiosis is an infrequent disease that affects patients who display a cellular immunodeficiency, such as transplant recipients on immunosuppressive treatment, but uncommonly associated with high morbidity and mortality rates. Disseminated Nocardiosis affecting the central nervous system (CNS), abdomen, skin, and lungs has been described in bone marrow, lung, and kidney transplant recipients. However, to our knowledge, no cases involving all of these structures have been reported in liver transplant recipients. Herein, we have reported a case of CNS, pulmonary, and cutaneous nocardiosis in a liver transplant recipient who experienced hepatitis C virus-related cirrhosis and hepatocellular carcinoma and received the organ from a non-heart-beating donor. At posttransplantation month 7 the patient was admitted to the emergency department with poor general health status, fever, edema, and subcutaneous nodules in the legs. A computed tomography scan revealed multiple nodules disseminated through both lungs, abdomen, brain, and subcutaneous tissue. A needle biopsy was performed into one of the subcutaneous nodules. Cultures of the material tested positive for Nocardia farcinica. Thus, we started treatment with intravenous sulfamethoxazole-trimethoprim (SMZ-TMP), shifting after 1 month to oral therapy. Radiological examination performed after 2 weeks of treatment showed a 70% reduction in subcutaneous, pulmonary, and cerebral lesions. After 6 months of SMZ-TMP treatment, the patient remained free of the symptoms with involution of the subcutaneous nodules and significant radiological improvement. Among opportunistic infections appearing in liver transplant recipients, Nocardia species should have special consideration according to the success of early treatment and the bad prognosis in cases of delayed diagnosis.

Antimicrobial resistance and phage and molecular typing of Salmonella strains isolated from food for human consumption in Spain.

The aims of this study were to ascertain the population structure and antimicrobial susceptibility of Salmonella enterica serovars isolated in 2002 from food in 16 Spanish regions. Serovars were characterized by serotyping, phage typing, antimicrobial susceptibility, and pulsed-field gel electrophoresis (PFGE) typing, and 264 nonrelated strains were selected for further analysis. The main sources were eggs and their derivatives (21.6% of strains), poultry and related products (16.6%), and seafood (16.3%). High serotype diversity was detected (51 serotypes); the most common were Enteritidis (n = 96, 36.3%) and Typhimurium (n = 53, 20.1%), followed by a miscellaneous group of 49 different serotypes (n = 115, 43.5%). A 15% increase in Salmonella Enteritidis isolation was observed. Common phage types for Salmonella Enteritidis were PT1 (41.6% of isolates), PT4 (9.4%), PT6 (9.4%), and PT6a (9.4%), and common types for Salmonella Typhimurium were DTU302 (18.8%), DT104 (15.1%), and DT104B (13.2%). Salmonella Enteritidis strains were categorized into eight PFGE types with a similarity of 81 to 96%, and 73.9% of the strains were grouped into just one cluster. Salmonella Typhimurium isolates were divided into 13 PFGE types with a similarity of 64 to 86%, and one predominant clone contained 41.5% of the strains. Resistance rates for Salmonella Enteritidis, Salmonella Typhimurium, and the miscellaneous group were, respectively, 8.3, 69.8, and 13.9% for ampicillin, 3.1, 52.8, and 59% for streptomycin, 40.6, 22.6, and 10.4% for nalidixic acid, 15.6, 71.7, and 31.1% for tetracycline, 7.3, 18.8, and 9.5% for trimethoprim-sulfamethoxazole, 0, 50.9, and 4.3% for chloramphenicol, and 6.2, 71.7, and 17.4% for multiple (at least four) antimicrobials. All the strains remained susceptible to other beta-lactams and fluoroquinolones. Surveillance of S. enterica isolated from food is strongly recommended to reduce community exposure to antimicrobial resistant strains.

Second case of neurocysticercosis in a patient with liver transplantation (first case in Spain): a case report.

BACKGROUND: Neurocysticercosis (NCC) is a disorder caused by the Taenia solium larva. It is the most common parasitosis of the central nervous system (CNS). Its distribution is universal, but it is endemic in many developing countries and in the third world. In Spain most patients come from countries where the condition is endemic. However, sporadic cases occur among the population of rural regions. NCC in transplant recipients is uncommon. One renal transplant recipient developed NCC but responded to treatment with praziquantel. Recently, it has been reported to complicate a liver transplantation. CASE REPORT: The patient was a 49-year-old Ecuatorian man who received a cadaveric donor liver graft in June 2001 due to acute liver failure induced by toadstool and was under treatment with FK506. In January 2006, the patient presented with a generalized onset of a tonic-clonic seizure for 1 minute without sphincter incontinence, headache, fever, or previous brain trauma. Neurological evaluation did not show evidence of organic brain dysfunction. The neuroimaging findings (brain) computed tomography scan, magnetic resonance imaging were compatible with NCC: many cystic lesions intra- and extraparenchymatous with a scolex visible in three of them. Serology for cysticercosis in plasma was initially indeterminate but positive afterward. The patient was treated with anticonvulsivants (valproic acid) and albendazole. Systemic steroids were added in order to reduce the edema produced upon death of the cyst. Treatment lasted 3 weeks and it was completed without complications or neurological symptoms. Liver function was not affected. One year later the patient remained asymptomatic. CONCLUSION: NCC is a condition that must be included in the differential diagnosis of patients with CNS involvement and cystic lesions on neuroimaging investigations in transplant recipients, especially patients originating from or traveling to endemic areas. First-line therapy for active cysts includes antiparasitic drugs (albendazole or praziquantel) as well as steroids and anticonvulsivants. In our patient, this therapy was effective.

Relationship of pulsed-field profiles with key phage types of Salmonella enterica serotype Enteritidis in Europe: results of an international multi-centre study.

Salmonella is one of the most common causes of foodborne infection in Europe with Salmonella enterica serovar Enteritidis (S. Enteritidis) being the most commonly identified serovar. The predominant phage type for S. Enteritidis is phage type (PT) 4, although PT 8 has increased in incidence. Within these phage types, pulsed-field gel electrophoresis (PFGE) provides a method of further subdivision. The international project, Salm-gene, was established in 2001 to develop a database of PFGE profiles within nine European countries and to establish criteria for real-time pattern recognition. It uses DNA fingerprints of salmonellas to investigate outbreaks and to evaluate trends and emerging issues of foodborne infection within Europe. The Salm-gene database contains details of about 11 700 S. Enteritidis isolates, demonstrating more than 65 unique PFGE profiles. The clonal nature of S. Enteritidis is evidenced by the high similarity and distribution of PFGE profiles. Over 56% (6603/11 716) of the submitted isolates of several different phage types were profile SENTXB.0001, although this profile is most closely associated with PT 4. The next most common profiles, SENTXB.0002 and SENTXB.0005, were closely associated with PT 8 and PT 21 respectively. Studies to investigate the relationship of profile types with outbreaks and possible vehicles of infection suggest that the incidence of PFGE profile SENTXB.0002, and thus PT 8, in some countries may be due to importation of foods or food production animals from Eastern Europe, where PT 8 is amongst the most frequently identified phage types. Collation of subtyping data, especially in the commonly recognized phage types, is necessary in order to evaluate trends and emerging issues in salmonella infection.

Epidemiological tracing of Salmonella enterica serotype Abortusovis from Spanish ovine flocks by PFGE fingerprinting.

Salmonella enterica serotype Abortusovis, an ovine host-specific serotype, rare in most countries, is responsible for epidemic abortion episodes in Spain. With the aim of surveillance and detection of the spread of specific clones, 55 Abortusovis isolates collected during 1996-2001 from flocks in 11 provinces, were studied using XbaI-PFGE. Despite the fact that the strains were geographically and spatially related, PFGE demonstrated an epidemiologically acceptable discriminating power, identifying 20 clones (similarity, 52-96%). Clones Sabv6, 1, 5 were disseminated in seven, five and two areas respectively, while another 17 clones appeared in single places. Clones from nearby geographic regions showed a high relatedness (one band of difference in the PFGE profile) Sabv1-2-3, Sabv5-6, Sabv7-8, and Sabv13-14, suggesting a common ancestor. Co-isolation in the same flock (Sabv5-6, Sabv1-3, Sabv1-6) was detected. PFGE surveillance detected the predominance and widespread distribution of clone Sabv6 in 21 out of the 55 Abortusovis serotype episodes studied in Spain.

First Spanish series of intestinal transplantation in adult recipients.

BACKGROUND: short-bowel transplantation has experienced a substantial growth worldwide following improved results from the late 1990's on, and its coverage by Medicare. According to the International Registry (1985-2005), a total of 1,292 intestinal transplants for 1,210 patients in 65 hospitals across 20 countries have been carried out thus far. OBJECTIVE: to know short-term (6 months) results regarding patient and graft survival from the first Spanish series of intestinal transplants in adult recipients. MATERIAL AND METHODS: we present our experience in the assessment of 20 potential candidates to short-bowel transplantation between June 2004 and October 2005. Of these, 10 patients were rejected and 4 were transplanted, which makes up the sample of our study. RESULTS: to this date 5 transplants have been carried out in 4 patients (2 retransplants, 2 desmoid tumors, 1 short bowel syndrome after excision as a result of mesenteric ischemia). Upon study completion and after a mean follow-up of 180 days (range 90-190 days) all recipients are alive, and all grafts but one (75%) are fully operational, with complete digestive autonomy. All patients received induction with alemtuzumab except one, who received thymoglobulin; in all induction was initiated with no steroids. CONCLUSIONS: intestinal transplantation represents a therapeutic option that is applicable in our setting and valid for recipients with an indication who have no other feasible alternative to keep their intestinal failure under control.

Incidence of de novo nonmelanoma skin tumors after liver transplantation for alcoholic and nonalcoholic liver diseases.

INTRODUCTION: Skin tumors are the most common malignancies after orthotopic liver transplantation (OLT). They have been related to sunlight exposure, tobacco consumption, and immunosuppression. The aim of this study was to compare the incidence of de novo skin tumors (nonmelanoma) in patients who underwent liver transplantation for alcoholic cirrhosis versus nonalcoholic diseases. PATIENTS AND METHODS: Between April 1986 and July 2004, we performed 1000 OLT in a population of 888 recipients. This study was performed in a sample of 701 adult recipients who survived >2 months after transplantation: 276 patients (39.4%) underwent OLT for alcoholic cirrhosis (AC-group), and 425 (60.6%) for nonalcoholic disease (N-AC). The overall incidence of de novo skin tumors was 3.5% (25 tumors): 5.4% (15 tumors) in the AC-group and 2.4% (10 tumors) in the N-AC group (P = .027). Two patients developed two tumors. There were 19 men and 4 women, mean age at OLT of 54.4 +/- 6.8 years (range, 40 to 66 years). The mean time from OLT to tumor diagnosis was 66.1 +/- 51.4 months (range, 3 to 165 months): 56.4 +/- 44.4 months in the AC-group versus 80.6 +/- 59.8 months in the N-AC group (P = NS). Histologically, 17 tumors (68%) were basal cell carcinomas and eight tumors (32%) were squamous cell carcinomas (P = .128). Fourteen patients (60.8%) were smokers: 11 patients (84.6%) in the AC-group versus 3 patients (30%) in the N-AC group (P = .012). All the patients underwent tumor resection, with only one patient dying, because of lymph node invasion of the neck. CONCLUSION: There was a higher incidence of de novo skin tumors among patients who smoked who underwent OLT for alcoholic cirrhosis.

Distribution of molecular subtypes within Salmonella enterica serotype Enteritidis phage type 4 and S. Typhimurium definitive phage type 104 in nine European countries, 2000-2004: results of an international multi-centre study.

This study investigates the distribution of pulsed-field gel electrophoresis (PFGE) profiles within Salmonella enterica serotype Enteritidis phage type (PT) 4 and S. Typhimurium definitive phage type (DT) 104, from cases of human infection in nine European countries from 2000 to 2004. Isolates were subtyped using standardized methods and gel images submitted by each participating country to the coordinating centre (Health Protection Agency Centre for Infections, London, UK), where they were entered into a central database, developed within BioNumerics software, and designated using an agreed nomenclature. S. Enteritidis PT4 (n=3637) was differentiated into 38 different profiles. Simpson's index of diversity (D) of profiles ranged from 0.2 to 0.4. Profile SENTXB.0001 represented at least 80% of all profiles in each country. S. Typhimurium DT104 (n=1202) was differentiated into 28 different profile types. Simpson's D was at least 0.6 in all countries except in Austria and Italy. In both these countries over 74% of S. Typhimurium DT104 profiles were STYMXB.0013. Profile STYMXB.0061, was predominant in Denmark, Spain, Finland and England and Wales where it represented between 36% and 45% of profiles. Profile STYMXB.0001 represented nearly half of all profiles in Scotland and 23% in England and Wales. PFGE is proving useful for further discrimination within S. Enteritidis PT4 and S. Typhimurium DT104. Ascertainment of international outbreaks involving common serotypes and phage types may be increased by the timely pooling of PFGE profiles within a central database readily accessible to all participating countries.

A foodborne outbreak of Salmonella infection due to overproduction of egg-containing foods for a festival.

A large outbreak of gastroenteritis occurred in Catalonia in June 2002 with 1435 cases and 117 hospitalizations. Consumption of a hard pastry with vanilla cream was strongly associated with illness. Stool samples from cases and food-handlers were analysed. The premises of the food manufacturer were inspected and food samples were taken for microbiological analysis. Salmonella serotype Enteriditis was isolated from 154 cases, three food-handlers and nine food samples. Outbreak-associated strains showed a coincident phage type, antibiotype and pulse-field gel electrophoresis pattern. Inadequate handling of foods containing eggs occurred because the establishment exceeded its safe food production capacity to meet demand for the pastry, which was consumed on the day of a traditional festival. Excessive production of foods for holidays or special events represents a potential public health threat.

Does preoperative fine needle aspiration-biopsy produce tumor recurrence in patients following liver transplantation for hepatocellular carcinoma?

INTRODUCTION: Liver transplantation (OLT) has been advocated for patients with carcinoma hepatocellular (HCC). A preoperative biopsy (fine needle aspiration biopsy) [FNA] facilitates preoperative diagnosis of adverse pathological factors: vascular invasion or histologicalic differentiation. But a biopsy may cause abdominal dissemination and be related to a higher incidence of recurrence. PATIENTS AND METHODS: From April 1986 to December 2003, we performed 95 OLT for HCC. We divided them in two groups: group A without FNA-biopsy (67.9%) and group B with FNA-biopsy (32.1%). RESULTS: We obtained the diagnosis of HCC in only 15 patients (57.6%). In two patients an OLT was avoided due to the presence of abdominal dissemination at the time of transplant. Recurrence incidence was higher among group B patients (5.9% vs 31.8%; P = .003) due to extrahepatic recurrence (2% vs 27.3%; P = .003). No differences were observed in morbidity or mortality. The two groups were homogeneous in epidemiological and pathological variables except: sex distribution, Child status, AFP level, tumor size, and pTNM stage. If we compare recurrence rates in the two groups attending to these nonhomogeneous variables, it was significantly higher among patients with tumors larger than 3 cm, pTNM I-III stage, Child B-C, AFP >200 ng/mL, and males or females. CONCLUSIONS: Preoperative liver biopsy is associated with a larger incidence of tumor recurrence, so we believe that it is not necessary prior to an OLT for HCC.

Short- and long-term outcomes after living donor liver transplantation.

INTRODUCTION: Living donor liver transplantation was first described as a way to alleviate the organ shortage. Extensive studies of both the prospective donor and the recipient are necessary to ensure successful outcome. In this paper we describe our results in 28 living donor liver transplantations from the perspective of the donor and the recipient. METHODS: A prospective, longitudinal, observational, comparative study was conducted from April 1995 to October 2004, including 28 living donor liver transplantations. RESULTS: After a mean follow-up time of 25.6 +/- 20.58 months, all donors are alive, showing normal liver function tests. All of them have been reincorporated into their normal lives. At the end of the study and after a mean follow-up time of 21.2 +/- 14.3 months, 86.3% of the adult recipients are alive. Actuarial recipient survivals at 6, 12, and 36 months were 86.36%. Actuarial mean survival time was 44 months (95% CI, 37 to 51). At the end of the study, 77.3% of the grafts are functioning. Actuarial graft survivals at 6, 12, and 36 months were 77.27%. Actuarial mean graft survival time was 32 months (95% CI, 25 to 39). The main complications were hepatic artery thrombosis (n = 2) and small for-size syndrome (n = 2). At a mean follow-up of 20.33 +/- 7.74 months, all pediatric recipients are alive. Actuarial recipient survivals at 12 and 36 months were 100% and actuarial graft survivals were 80%. CONCLUSIONS: Living donor liver transplantation may increase the liver graft pool, and therefore reduce waiting list mortality. Nevertheless caution must be deserved to avoid surgical morbidity and mortality in with the donor the recipient.

Hepatic vein reconstruction in living donor liver transplantation.

INTRODUCTION: Living donor liver transplantation has emerged as a response to the cadaveric graft shortage, especially for adult recipients. Both right and left liver grafts are widely used, although some technical problems remain unresolved. Herein we describe our technique for reconstruction of the venous outflow in living donor liver transplantation. METHODS: From April 1986 to September 2004, 1012 liver transplantations were performed including 30 living donor liver transplantations between April 1995 and September 2004. We have selected the first 28 cases to ensure a mean follow-up of 21.07 +/- 13.11 months. We transplanted 18 right lobe grafts, 7 left lobe grafts, and 3 left lateral segment grafts. A surgical technique is described herein. RESULTS: No venous outflow obstruction developed among living donor liver transplantation recipients. CONCLUSION: We recommend reconstruction of the hepatic veins in living donor liver transplantation including joining together the three hepatic veins in the recipient to avoid venous outflow obstruction.

Fecal shedding of Escherichia coli O157, Salmonella, and Campylobacter in Swiss cattle at slaughter.

Fecal samples from 2,930 slaughtered healthy cattle were examined with the following goals: (i) to monitor the shedding of Escherichia coli O157, Salmonella, and Campylobacter in cattle; and (ii) to further characterize the isolated strains. The percentage of the 2,930 samples that tested positive for E. coli O157 by PCR was 1.6%. Thirty-eight strains from different animals that agglutinated with Wellcolex E. coli O157 were isolated. Of the six sorbitol-negative strains, five tested positive for stx2 genes (two times for stx2c and three times for stx2), and one strain tested positive for stx1 and stx2c genes. All sorbitol-negative strains belonged to the serotypes O157:H7- and O157:H7 and harbored the eae type gamma 1 and ehxA genes. The 32 sorbitol-positive strains tested negative for stx genes and belonged to the serotypes O157:H2, O157:H7, O157:H8, O157:H12, O157:H19, O157:H25, O157:H27, O157:H38, O157:H43, O157:H45, and O157:H-. All O157:H45 strains harbored the eae subtype alpha 1 and therefore seem to be atypical enteropathogenic E. coli strains. Whereas none of 1,000 examined samples was positive for Salmonella, 95 of 935 (10.2%) samples were positive for Campylobacter, and all strains were identified as C. jejuni. Sixteen Campylobacter strains were resistant to tetracycline, five were resistant to nalidixic acid/ciprofloxacin, four were resistant to streptomycin, and one was resistant to nalidixic acid/ciprofloxacin and streptomycin. Fecal shedding of zoonotic pathogens in slaughter animals is strongly correlated with the hazard of carcass contamination. Therefore, the maintenance of slaughter hygiene is of crucial importance.

Exceptional bilateral adrenalectomy after secondaries from colorectal cancer.

We report a very uncommon case of bilateral adrenal metastasis treated at our institution. The patient was 65 years old, with a history of low anterior resection for colorectal cancer in 2001. One year later, he was diagnosed with bilateral adrenal metastasis, based on the results of abdominal computed tomography-scan. A bilateral adrenalectomy extended to distal pancreatectomy and splenectomy was performed. Postoperative course was uneventful. He is alive and free of disease 12 months after adrenalectomy. We conclude adrenal metastasis from colorectal cancer should be managed surgically, even if they are bilateral.
