RESUMO
BACKGROUND: Renoportal anastomosis (RPA) is an effective technique in cases of complex portal vein thrombosis with the presence of a splenorenal shunt. The objective of this report is to describe the possible complications related to RPA. CASE REPORT: A 50-year-old man with alcohol-related and hepatitis C-related cirrhosis and 2 hepatocellular carcinomas underwent liver transplant. He presented a portal vein thrombosis Yerdel IV, a splenorenal shunt, and another shunt between the inferior mesenteric vein (IMV) and the perirectal plexus. During surgery, the flow of the left renal vein was 891 mL/min, and this rose to 1050 mL/min after IMV clamping. RPA was made through iliac vein graft interposition, and the IMV was ligated. Portal flow was 832 mL/min but drastically decreased because of mesenteric root compression. After finishing the liver transplant, a renoiliac graft percutaneous transhepatic stent was put in place. The patient presented graft dysfunction and acute kidney injury. On postoperative day +18, a second stent was put in place because of a thrombosis in the splenomesenteric confluence. The patient subsequently presented partial distal rethrombosis and a pancreaticoduodenal arteriovenous fistula, which required several embolizations. The patient developed ascites, recurrent gastrointestinal bleeding, and persistent bacterial peritonitis. Finally, a modified Sugiura procedure (without splenectomy) was performed, achieving a portal flow of 1800 mL/min. However, the patient developed sepsis and multiorgan failure, and died on postoperative day +70. CONCLUSIONS: Despite long-term patient and graft survival within accepted limits after LT, RPA is a challenging technique not exempt from complications.

BACKGROUND: Management of nonsplenorenal spontaneous portosystemic shunts (NSRSPSS) in liver transplant (LT) is controversial. Reports on the influence of its ligation suggest improvements in morbidity and survival. METHODS: Retrospective study of a single-center series. The objective was to analyze the outcomes and post-LT survival after the closure of NSRSPSS. RESULTS: Between January 2005 and April 2021 a total of 23 patients with NSRSPSS underwent LT. The shunt was superior mesenteric vein-vena cava in 12 (52.2%), inferior mesenteric vein-vena cava in 6 (26.1%), through the left gastric vein in 4 (17.4%), and portocava in 1 (4.3%). Seven patients presented portal vein thrombosis, with thrombectomy being performed in 5. Moreover, 21 patients had portoportal anastomosis, 1 patient required portal reconstruction at the splenomesenteric confluence, and 1 had a coronary-portal anastomosis. The NSRSPSS was closed in 22 cases (95.7%). The mean (SD) portal flow before and after the closure of NSRSPSS was 1395 (572) mL/min and 1773 (583) mL/min (104.4 [47.9] mL/min/100 g and 127.9 [4.9] mL/min/100 g, respectively). Six patients (26.1%) presented primary graft dysfunction, 13 (56.5%) acute kidney injury, and 9 (39%) ascites. Three arterial stenoses (13%), 2 biliary stenoses (8.6%), and 1 intrahepatic portal thrombosis (4.3%) occurred. Median intensive care unit and hospital stay was 5 days (range, 3-8 days) and 15 days (range, 13-21 days). After a mean follow-up of 5.18 (3.2) years, all patients except 1 are alive. CONCLUSIONS: The closure of the NSRSPSS during LT can optimize portal flow, with potential influence in morbidity and survival rates.

Although good results have been reported with the use of normothermic regional perfusion (NRP) in controlled donation after circulatory death (cDCD) liver transplantation (LT), there is a lack of evidence to demonstrate similar results to donation after brain death (DBD). We present a single-center retrospective case-matched (1:2) study including 100 NRP cDCD LTs and 200 DBD LTs and a median follow-up of 36 months. Matching was done according to donor age, recipient Model for End-Stage Liver Disease score, and cold ischemia time. The following perioperative results were similar in both groups: alanine transaminase peaks of 909 U/L in the DBD group and 836 U/L in the cDCD group and early allograft disfunction percentages of 21% and 19.2%, respectively. The 1-year and 3-year overall graft survival for cDCD was 99% and 93%, respectively, versus 92% and 87%, respectively, for DBD (P = 0.04). Of note, no cases of primary nonfunction or ischemic-type biliary lesion were observed among the cDCD grafts. Our results confirm that NRP cDCD LT meets the same outcomes as those obtained with DBD LT and provides evidence to support the idea that cDCD donors per se should no longer be considered as "marginal donors" when recovered with NRP.

BACKGROUND: Tacrolimus trough levels (TTL) during the first weeks after liver transplantation (LT) have been related with long-term renal function and hepatocellular carcinoma recurrence. Nevertheless, the significance of trough levels of tacrolimus during the early post-transplant period for the long-term outcome is under debate. AIM: To evaluate the effect of TTL during the first month on the long-term outcomes after LT. METHODS: One hundred fifty-five LT recipients treated de novo with once-daily tacrolimus were retrospectively studied. Patients with repeated LT or combined transplantation were excluded as well as those who presented renal dysfunction prior to transplantation and/or those who needed induction therapy. Patients were classified into 2 groups according to their mean TTL within the first month after transplantation: ≤ 10 (n = 98) and > 10 ng/mL (n = 57). Multivariate analyses were performed to assess risk factors for patient mortality. RESULTS: Mean levels within the first month post-transplant were 7.4 ± 1.7 and 12.6 ± 2.2 ng/mL in the ≤ 10 and > 10 groups, respectively. Donor age was higher in the high TTL group 62.9 ± 16.8 years vs 45.7 ± 17.5 years (P = 0.002) whilst mycophenolate-mofetil was more frequently used in the low TTL group 32.7% vs 15.8% (P = 0.02). Recipient features were generally similar across groups. After a median follow-up of 52.8 mo (range 2.8-81.1), no significant differences were observed in: Mean estimated glomerular filtration rate (P = 0.69), hepatocellular carcinoma recurrence (P = 0.44), de novo tumors (P = 0.77), new-onset diabetes (P = 0.13), or biopsy-proven acute rejection rate (12.2% and 8.8%, respectively; P = 0.50). Eighteen patients died during the follow-up and were evenly distributed across groups (P = 0.83). Five-year patient survival was 90.5% and 84.9%, respectively (P = 0.44), while 5-year graft survival was 88.2% and 80.8%, respectively (P = 0.42). Early TTL was not an independent factor for patient mortality in multivariate analyses. CONCLUSION: Differences in tacrolimus levels restricted to the first month after transplant did not result in significant differences in long-term outcomes of LT recipients.
RESUMO
COVID-19, the illness caused by the SARS-CoV-2 virus originated in December 2019 in Wuhan, China and has caused more 3,3 million cases and more than 230,000 deaths throughout the world, with 25,000 of them only in Spain, where the first case was diagnosed on January 31st, 2020. As COVID-19 is a "new" disease, we still do not have data on prognosis or treatment in transplant patients or on how to manage immunosuppression in this complex scenario. We present a case of COVID-19 diagnosed during the early postoperative period in a recipient whose liver transplantation was performed on late March during the lockdown in Spain, with donor and recipient previously negative rRT-PCR to SARS-CoV-2. In the first post-operative week the patient suffered COVID-19 pneumonia that was treated with immunosuppression minimization, oral Hydroxycloroquine and Azithromycin with favorable outcome. The patient was discharged on POD 21 without complications. To date, few early post-liver transplantation SARS-CoV-2 infected recipients have been published, but only one was an early postoperative infection. In our case the outcome was favorable, even though it was an early post -liver transplantation COVID-19 in a frail patient.
RESUMO
BACKGROUND AND AIM: Renal dysfunction is related to short- and long-term survival after liver transplantation. We present herein a retrospective analysis of our experience with liver transplantation in recipients with pretransplant renal dysfunction treated with induction therapy followed by delayed/reduced de novo once-daily tacrolimus. METHODS: Liver transplantations performed between April 2008 and August 2011 were included in this study. Pretransplant renal dysfunction was defined as estimated glomerular filtration rate <60 mL/min. Interleukin-2 receptor antagonists were used for induction therapy. Initial once-daily tacrolimus dose was 0.10 mg/kg/day or 0.07 mg/kg/day if combined with mycophenolate mofetil (MMF). Tacrolimus target trough levels were 4 to 6 ng/mL during the first post-transplant year and <4 ng/mL the rest of the follow-up. RESULTS: Nineteen patients comprised the study cohort with a median follow-up of 56.4 months (range, 11-78). Median day of tacrolimus introduction was 7 (range, 3-12). Once-daily tacrolimus was withdrawn in 6 patients (31.6%) due to evolution of renal dysfunction in all cases. At 5 years, 30% of the patients were under MMF monotherapy. Mean tacrolimus trough levels were maintained under 5 ng/mL. Mean estimated glomerular filtration rate at 5 years was 55.3 ± 12.7 mL/min. No patient needed hemodialysis or renal transplantation over the follow-up. Patient survival at 5 years was 78.9%. CONCLUSIONS: Induction therapy followed by delayed/reduced de novo once-daily tacrolimus and maintenance of low tacrolimus exposition during the follow-up is effective to maintain long-term renal function and to achieve favorable patient survival in liver transplant recipients with pretransplant renal dysfunction.

BACKGROUND: Controlled donation after circulatory death (cDCD) has been associated with a high incidence of ischemic cholangiopathy and other perioperative complications. In an attempt to avoid these complications, we implemented an active protocol of cDCD liver transplant (LT) with normothermic regional perfusion (NRP) preservation. METHODS: This is a descriptive analysis of data collected from a prospective date base of cDCD LT preserved with NRP from January 2015 to June 2017 with a minimum follow up of 9 months. RESULTS: Fifty-seven potential cDCD donors were connected to the NRP system. Of these, 46 livers were transplanted over a 30-month period (80% liver recovery rate). The median posttransplant peak in alanine transaminase was 1136 U/L (220-6683 U/L). Seven (15%) patients presented postreperfusion syndrome and 11 (23%) showed early allograft dysfunction. No cases of ischemic cholangiopathy were diagnosed, and no graft loss was observed over a medium follow-up period of 19 months. Of note, 13 donors were older than 65 years, achieving comparable perioperative and midterm results to younger donors. CONCLUSIONS: As far as we know, this represents the largest published series of cDCD LT with NRP preservation. Our results demonstrate that cDCD liver grafts preserved with NRP appear far superior to those obtained by the conventional rapid recovery technique.

The once-daily prolonged-release formulation of tacrolimus has been recently related with significant graft and patient mid-term survival advantages; however, practical information on the de novo administration after liver transplantation and longterm outcomes is currently lacking. This study is a 5-year retrospective analysis of a single-center cohort of liver transplant recipients treated de novo with once-daily tacrolimus (April 2008/August 2011). The study cohort consisted of 160 patients, including 23 with pretransplant renal dysfunction, with a median follow-up of 57.6 months (interquartile range, 46.6-69.0). Tacrolimus target trough levels were 5-10 ng/mL during the first 3 months after transplant, reducing progressively to <7 ng/mL after the first posttransplant year. Once-daily tacrolimus was withdrawn in 35 (21.8%) patients during follow-up, mostly due to renal dysfunction and/or metabolic syndrome. The biopsy-proven acute rejection rate was 12.5% with no cases of steroid-resistant rejection. The cumulative incidence of de novo diabetes, hypertension, and dyslipidemia were 16.9%, 31.2%, and 6.5%, respectively. Hepatocellular carcinoma recurrence rate was 2.8%. Renal function remained stable after the sixth month after transplant with a mean estimated glomerular filtration rate of 77.7 ± 19.6 mL/minute/1.73 m(2) at 5 years. None of our patients developed chronic kidney disease stage 4 or 5. Patient survival at 1, 3, and 5 years was 96.3%, 91.9%, and 88.3%, respectively. Overall survival of patients with Model for End-Stage Liver Disease (MELD) score > 25 points was not significantly different. In conclusion, our study suggests that immunosuppression based on de novo once-daily tacrolimus is feasible in routine clinical practice, showing favorable outcomes and outstanding longterm survival even in patients with high MELD scores.

Limited data exist evaluating outcomes in patients with serious Streptococcus anginosus group infections, particularly bacteraemia. A retrospective, single-centre cohort study was conducted to characterize potential risk factors along with clinical and microbiological outcomes in patients with S. anginosus group bacteraemia (SAGB). Adult inpatients with SAGB identified using the Verigene Gram-positive blood culture assay between March 2013 and April 2014 were included. Patients aged ≤ 18 or >89 years, those with SAGB identified at an outside facility and those who were incarcerated were excluded. Differences between groups were explored using a Wilcoxon rank-sum test, χ2 test, Student's t-test or Fisher's exact test as appropriate and a two-tailed P value of ≤ 0.05 was considered statistically significant. The 34 patients who met the inclusion criteria were 57 ± 14 (mean ± SD) years old and had a median Charlson co-morbidity index of 4 [interquartile range (IQR) 1-6] and 10 (29%) were immunosuppressed at baseline. Almost half (47%) had received antibiotics in the previous 90âdays. Twelve (35%) patients had gastrointestinal malignancies and the commonest source of bacteraemia was the gastrointestinal tract (53%). The primary species responsible for SAGB was S. anginosus (68%), and overall susceptibility to penicillin was 91%. Patients were most often treated with a ß-lactam/ß-lactamase inhibitor combination (36%) for a duration of 8 (IQR 4-13) days. Length of stay (LOS) and infection-related LOS were 10 (IQR 5-17) and 9 (IQR 4-12) days, respectively. Twenty [59%] patients achieved a clinical cure, while 29 (85%) achieved a microbiological cure. Four (12%) patients died and one patient was readmitted within 30â days. In the largest cohort of patients with SAGB to date, gastrointestinal malignancies may have been an important risk factor for SAGB, while rapid identification via a microarray assay likely contributed to improved disease recognition and timely pharmacological and non-pharmacological therapy.

The objective of the study was to analyze the descriptive epidemiology and costs of herpes zoster (HZ) and postherpetic neuralgia (PHN) in people aged ≥50 years in Catalonia (Spain). The incidence of HZ in Catalonia was estimated by extrapolating the incidence data from Navarre (Spain) to the population of Catalonia. The incidence of PHN was estimated according to the proportion of cases of HZ in the case series of the Hospital del Sagrado Corazón de Barcelona that evolved to PHN. Drug costs were obtained directly from the prescriptions included in the medical record (according to official prices published by the General Council of the College of Pharmacists). The cost of care was obtained by applying the tariffs of the Catalan Health Institute to the number of outpatient visits and the number and duration of hospital admissions. The estimated annual incidence of HZ was 31 763, of which 21 532 (67.79%) were in patients aged ≥50 years. The respective figures for PHN were 3194 and 3085 (96.59) per annum, respectively. The mean cost per patient was markedly higher in cases of PHN (916.66 euros per patient) than in cases of HZ alone (301.52 euros per patient). The cost increased with age in both groups of patients. The estimated total annual cost of HZ and its complications in Catalonia was 9.31 million, of which 6.54 corresponded to HZ and 2.77 to PHN. This is the first Spanish study of the disease burden of HZ in which epidemiological data and costs were collected directly from medical records. The estimated incidence of HZ is probably similar to the real incidence. In contrast, the incidence of PHN may be an underestimate, as around 25% of patients in Catalonia attend private clinics financed by insurance companies. It is also probable that the costs may be an underestimate as the costs derived from the prodromal phase were not included. In Catalonia, HZ and PHN cause an important disease burden (21 532 cases of HZ and 3085 de PHN with an annual cost of 9.31 million) in people aged ≥50 years, in whom vaccination is indicated.

Pancreaticopleural fistula is an uncommon clinical entity that appears in patients with a history of chronic pancreatitis. Apropos of the case of a 40-year-old man in our hospital, we reviewed the literature and found 40 publications with little more than 100 patients. All of these publications highlight the atypical presentation with dyspnea as the first symptom and stress that diagnosis is based on magnetic resonance pancreatography. Endoscopic retrograde cholangiopancreatography is used in confusing cases and in planning the optimal surgical approach. Initial treatment should consist of conservative medical therapy, including total parenteral nutrition and somatostatin or its analogues. If the fistula persists or recurs, various options are available such as surgery, placement of a transpapillary pancreatic stent or nasopancreatic tube. The overall mortality rate from pancreaticopleural fistula is approximately 5%.
