RESUMEN
COVID-19 is commonly associated with high serum levels of pro-inflammatory cytokines, and the post-infection status can disturb self-tolerance and trigger autoimmune responses. We are reporting a 45-year-old male who was admitted with fatigue, jaundice, elevated liver enzymes (with cholestatic pattern), and acute kidney injury two weeks after recovering from a mild SARS-CoV-2 infection. Serologies for viral hepatitis and anti-mitochondrial antibody were negative, while anti-nuclear and anti-smooth muscle antibodies were positive. There were no signs of chronic liver disease, and a magnetic resonance cholangiography showed no dilatation of biliary ducts. Histologic evaluation of the liver evidenced numerous foci of lobular necrosis without ductopenia or portal biliary reaction. Considering the autoantibody profile and histologic changes, the medical team started oral prednisone, but there was a suboptimal biochemical response in the outpatient follow-up. Two months later, a second liver biopsy was performed and revealed non-suppurative destructive chronic cholangitis, extensive areas of confluent necrosis with hepatocytes regenerating into pseudorosettes, and numerous plasma cells. According to the Paris Criteria, the patient was then diagnosed with an autoimmune hepatitis-primary biliary cholangitis overlap syndrome (AIH-PBC-OS). After adding azathioprine and ursodeoxycholic acid to the treatment, there was a satisfactory response. This is the second worldwide report of an AIH-PBC-OS triggered by COVID-19, but the first case with a negative anti-mitochondrial antibody. In this setting, histologic evaluation of the liver by an experienced pathologist is a hallmark of achieving the diagnosis and correctly treat the patient.

RESUMEN
With the emergence of new variants of SARS-CoV-2, questions about transmissibility, vaccine efficacy, and impact on mortality are important to support decision-making in public health measures. Modifications related to transmissibility combined with the fact that much of the population has already been partially exposed to infection and/or vaccination, have stimulated recommendations to reduce the isolation period for COVID-19. However, these new guidelines have raised questions about their effectiveness in reducing contamination and minimizing impact in work environments. Therefore, a collaborative task force was developed to review the subject in a non-systematic manner, answering questions about SARS-CoV-2 variants, COVID-19 vaccines, isolation/quarantine periods, testing to end the isolation period, and the use of masks as mitigation procedures. Overall, COVID-19 vaccines are effective in preventing severe illness and death but are less effective in preventing infection in the case of the Omicron variant. Any strategy that is adopted to reduce the isolation period should take into consideration the epidemiological situation of the geographical region, individual clinical characteristics, and mask for source control. The use of tests for isolation withdrawal should be evaluated with caution, due to results depending on various conditions and may not be reliable.

BACKGROUND: This study aimed to assess the prevalence of Bartonella sp.-DNA detection in blood and skin samples from patients with non-viral end-stage liver disease awaiting liver transplantation. METHODOLOGY/PRINCIPAL FINDINGS: Blood samples and healthy skin fragments from 50 patients were tested using microbiological and molecular methods. Fifteen patients had cryptogenic hepatitis (CH) and 35 had alcoholic, drug-induced or autoimmune liver disease. DNA was extracted from whole blood and liquid culture samples, isolates, and skin fragments. Thirteen of the 50 patients (26%) had Bartonella henselae DNA detection in their blood (9/50) and/or skin (5/50) samples. Colonies were isolated in 3/50 (6%) and infection was detected in 7/50 (14%) of the 50 patients. B. henselae-DNA detection was more prevalent in patients with CH than in other patients (p = 0.040). Of 39 patients followed-up for at least two years, a higher mortality rate was observed among patients with CH infected with B. henselae (p = 0.039). CONCLUSIONS/SIGNIFICANCE: Further studies assessing the role of B. henselae infection in the pathogenesis of hepatitis patients must be urgently conducted.

BACKGROUND: Current literature reports diverge on the impact of COVID-19 in liver transplant (LT) recipients. Literature findings often report conflicting results, relying on small sample sizes, limited ethnic variability, and nonstandardized methodologies. Notably, there are no studies on this topic regarding Latin American populations. This study seeks to report the impact of COVID-19, disease characteristics, and progression in LT recipients in a Latin American academic center environment. METHODS: The study design was a historic cohort, including adult LT recipient patients with suspected or confirmed COVID-19 who sought care between December 2019 to October 2021. The primary end point was defined as COVID-19-related death. Demographic, clinical, and laboratory data was also collected. RESULTS: Twenty-seven patients were included, representing a 3.5% incidence within 752 patients in the follow-up. The mean age and years from transplantation were 54 (SD ± 11) and 6.3 years (SD ± 5.4), respectively. Most patients were white (23 - 85.2%) and male (21 - 25.2%). The hospitalization rate was 55.6%, and 5 patients (18.5%), all of whom subsequently died, were admitted to the intensive care unit. Neither the presence of comorbidities nor advanced age were related to lethality. Patients with immunosuppression modifications (P = 0.039) or isolated tacrolimus suspension (P = 0.006) were associated with increased mortality. CONCLUSIONS: This study described COVID-19 infections in LT recipients in Latin American populations. This group was not affected by common factors associated with higher lethality, and displayed a tendency toward lower hospitalization rates. Our study concurred with previously reported evidence of a protective association of tacrolimus maintenance during treatment in LT recipients affected by COVID-19.

Cryptococcus neoformans is rarely associated with peritonitis in cirrhotic patients; nevertheless, it has a high mortality rate. Early diagnosis and prompt treatment may be the determining prognostic factors. This is a report of two patients awaiting a liver transplant who had opposite outcomes after the diagnosis of spontaneous cryptococcal peritonitis. In Patient 1, the fungal culture was positive in the blood and ascites. She had a poor evolution and died, which was likely caused by the delayed diagnosis and concomitant bacterial infections. In Patient 2, the fungus was found in the ascites, urine, and cerebrospinal fluid cultures. Antifungal treatment was effective. He underwent a liver transplant on the 83rd day of antifungal therapy and is still alive 1 year later. It is important to suspect fungal etiology when there is a lack of response to antibiotics in patients with decompensated cirrhosis and spontaneous peritonitis, and physicians must be aware of leukocyte count in the ascitic fluid, which is not so high in these cases. This report also emphasizes the need for the routine use of blood culture bottles for microbiological analysis of the ascitic fluid, as it was helpful to diagnose fungal peritonitis in both cases.

Bloodstream infections are a major factor contributing to morbidity and mortality following liver transplantation. The increasing occurrence of multidrug-resistant bloodstream infections represents a challenge for the prevention and treatment of those infections. The aim of this study was to evaluate the occurrence and microbiological profile of bloodstream infections during the early postoperative period (from day 0 to day 60) in patients undergoing liver transplantation from January 2005 to June 2016 at the State University of Campinas General Hospital. A total of 401 patients who underwent liver transplantation during this period were included in the study. The most common cause of liver disease was hepatitis C virus cirrhosis (34.01%), followed by alcoholic disease (16.24%). A total of 103 patients had 139 microbiologically proven bloodstream infections. Gram-negative bacteria were isolated in 63.31% of the cases, gram-positive bacteria in 28.78%, and fungi in 7.91%. Fifty-six infections (43.75%) were multidrug-resistant bacteria, and 72 (56.25%) were not. There was no linear trend concerning the occurrence of multidrug-resistant organisms throughout the study period. Patients with multidrug-resistant bloodstream infections had a significantly lower survival rate than those with no bloodstream infections and those with non-multidrug-resistant bloodstream infections. In conclusion, the occurrence of bloodstream infections during the early postoperative period was still high compared with other profile patients, as well as the rates of multidrug-resistant organisms. Even though the occurrence of multidrug resistance has been stable for the past decade, the lower survival rates associated with that condition and the challenge related to its treatment are of major concern.

Yellow fever (YF) is a viral disease, with clinical presentation among immunosuppressed patients not fully understood. YF vaccination (YFV), a live vaccine, is contraindicated in patients receiving immunosuppressive treatment due to the risk of developing the disease after vaccination. We report a case of a 50-year-old male recipient who presented wild-type YF five years after a deceased donor kidney transplant. He lived in a YF endemic area and inadvertently received YFV. One day after YFV, the patient presented nausea, vomiting, fever, diarrhea, polyarthralgia, thrombocytopenia, and increased levels of liver function enzymes. The serological test was compatible with YF disease, and quantitative viral load confirmed the diagnosis of wild-type YF. The patient received supportive care for twelve days, with hospital discharge in good clinical condition and stable renal function. One month after discharge, the patient developed de novo donor-specific anti-HLA antibodies (DSA) and histological evidence of endothelial lesion, with a diagnosis of acute antibody-mediated rejection (AMR), treated with plasmapheresis and human IVIg therapy. Six months after therapy, he presented normal renal function with a reduction of DSA MFI. In the reported case, we observed a clinical wild-type YF diagnosed even after YF vaccine administration, with good clinical outcome. De novo DSA and AMR occurred after the recovering of disease, with an adequate response to therapy and preserved allograft function. We reviewed the published literature on YF and YFV in solid organ transplantation.

BACKGROUND: Outpatient parenteral antimicrobial therapy (OPAT) has been used for decades in different countries to reduce hospitalization rates, with favorable clinical and economic outcomes. This study assesses the cost-utility of OPAT compared to inpatient parenteral antimicrobial therapy (IPAT) from the perspective of a public university hospital and the Brazilian National Health System (Unified Health System -SUS). METHODS: Prospective study with adult patients undergoing OPAT at an infusion center, compared to IPAT. Clinical outcomes and quality-adjusted life year (QALY) were assessed, as well as a micro-costing. Cost-utility analysis from the hospital and SUS perspectives were conducted by means of a decision tree, within a 30-day horizon time. RESULTS: Forty cases of OPAT (1112 days) were included and monitored, with a favorable outcome in 97.50%. OPAT compared to IPAT generated overall savings of 31.86% from the hospital perspective and 26.53% from the SUS perspective. The intervention reduced costs, with an incremental cost-utility ratio of -44,395.68/QALY for the hospital and -48,466.70/QALY for the SUS, with better cost-utility for treatment times greater than 14 days. Sensitivity analysis confirmed the stability of the model. CONCLUSION: Our economic assessment demonstrated that, in the Brazilian context, OPAT is a cost-saving strategy both for hospitals and for the SUS.

BACKGROUND: Hepatitis C virus (HCV) infection is the major cause of end-stage liver disease (LD) worldwide. The aim of this study was to assess sustained virological response (SVR) rates in a real-world cohort of patients with HCV infection treated with interferon-free direct antiviral agents (DAA). PATIENTS AND METHODS: All patients with genotypes 1, 2 or 3 HCV infection who started interferon-free treatment at a university hospital from December 2015 through July 2017 were included. The primary outcome was SVR at post-treatment week 12 by intention-to-treat (ITT) and modified ITT (mITT) analysis. RESULTS: Five hundred twenty seven patients were enrolled, 51.6% with cirrhosis. Most patients received sofosbuvir + daclatasvir + ribavirin (60.7%) and sofosbuvir + simeprevir (25.6%). Overall SVR rates were 90.5% for ITT and 96% for mITT. SVR rates were higher in non-cirrhotic (94.2% in ITT and 96.8% in mITT) versus cirrhotic patients (87.1% in ITT and 95.2% in mITT). In ITT and mITT assessments, SVR rates were higher in patients with Child-Pugh A (n = 222, 88.7% and 95.7%, respectively) versus Child-Pugh B or C (n = 40, 80% and 90%, respectively); SVR rates were higher in patients with genotype 1 (n = 405, 92.1% and 98.2%), followed by genotype 2 (n = 13, 84.6% and 92.7%) and genotype 3 (n = 109, 84.4% and 88.4%). Lower comorbidity index (p = 0.0014) and absence of cirrhosis (p = 0.0071) were associated with SVR. Among cirrhotic patients, lower Model for End-Stage Liver Disease (p = 0.0258), higher albumin (p = 0.0015), and higher glomerular filtration rate (p = 0.0366) were related to SVR. Twenty-two cirrhotic patients (8%) had clinical liver decompensation during treatment. Complications of advanced LD were responsible for discontinuation of treatment and death in 12 and 7 patients, respectively. CONCLUSION: Treatment with all-oral DAA achieved high SVR rates, particularly in patients without cirrhosis and few comorbidities. Advanced LD is associated to poor outcome, such as treatment failure and death.

AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation. METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index (BMI) 27.3 ± 4.5 kg/m(2) and Model for End-Stage Liver Disease (MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m(2) and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure (MIP) and maximal expiratory pressure, spirometry, root mean square (RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT(®), lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference (P = 0.01) between the first (initial) and the third month (final) MIP in the control group and in the intervention group, but there was no difference (P = 0.45) between the groups. The RMS of the diaphragm was lower (P = 0.001) and the functional capacity was higher (P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group (P = 0.01) and the intervention group (P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group (P = 0.083) and intervention group (P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups (P = 0.21). In the intervention group, patients with ascites at the end of the time period had decreased scores on the social aspects SF-36 domain (P = 0.023) compared to those who had no ascites. CONCLUSION: The proposed exercises provide an increase in the inspiratory muscle strength and improve functional capacity, consequently bettering the quality of life of liver disease patients.
RESUMEN
BACKGROUND: - In chronic liver disease, trace element levels in plasma are usually low. However, the specific cause and functional implications of this abnormality are yet not well understood. These element levels may decrease as a result of abnormal liver function in patients with cirrhosis and/or malnutrition. OBJECTIVE: - To evaluate the nutritional status and the profile of trace elements in plasma of patients with cirrhosis on a liver transplant list and to correlate them with disease severity. METHODS: - This cross-sectional study evaluated 31 male patients diagnosed with compensated liver cirrhosis on a waiting list for liver transplant. Nutritional status was objectively evaluated through anthropometry using Mendenhall score and Blackburn classification, subjectively through the Detsky questionnaire and severity of the disease by MELD and CTP score. Trace elements (Zn, Se, Cu, Ca, Fe, Mg and Mn) in plasma were analyzed by inductively coupled plasma mass spectrometry (ICP-MS). Statistical analysis was performed using Mann-Whitney test. RESULTS: - According to the nutritional assessment 19 (61.3%) were malnourished and 12 (38.7%) were overweight. Regarding disease severity 12 (39%) were classified as Child A, 17 (55%), Child B and 2 (6%) Child C, with 46.9% of patients with MELD score >17. The trace element analysis indicated that 31 (100%) had Mn levels above the reference range, 23 (74.2%) low levels of Cu, 29 (93.5%) with deficiency of Se, and 31 (100%) low levels of Ca and Mg. Disease severity did not show statistical difference between the studied trace elements, in contrast to the nutritional status, in which the malnourished group showed higher levels of Mn (P=0.01) and Fe (P=0.01) and low levels of Zn (P=0.03) when compared to the overweight group. CONCLUSION: - The results showed that the trace elements in plasma are altered in chronic liver disease; without significant correlation to disease severity, but correlated to nutritional status. Malnutrition is present in the patients studied, nonetheless a new scenario with an increase in the prevalence of overweight was verified regardless of the degree of hepatic decompensation.

RESUMO Contexto - Na doença hepática crônica os níveis plasmáticos de oligoelementos normalmente apresentam-se baixos, mas a causa específica e implicações funcionais desta anormalidade ainda não estão bem esclarecidas. Estes elementos podem estar diminuídos em consequência da função hepática alterada em pacientes com cirrose e/ou desnutrição. Objetivo - Avaliar o estado nutricional e o perfil de oligoelementos plasmáticos dos pacientes com cirrose hepática em lista para transplante e correlacionar com a gravidade da doença. Métodos - Trata-se de um estudo transversal, no qual foram avaliados 31 pacientes do sexo masculino com diagnóstico de cirrose hepática compensada em lista de espera para transplante de fígado. O estado nutricional foi avaliado objetivamente por medidas antropométricas através do escore de Mendenhall e classificado segundo Blackburn, subjetivamente por um questionário sistematizado por Detsky e a gravidade da doença pelo escore MELD e CTP. Os oligoelementos plasmáticos (Zn, Se, Cu, Ca, Fe, Mg e Mn) foram analisados pelo método de espectrometria de massas com fonte de plasma indutivamente acoplado (ICP-MS). Para análise estatística foi utilizado o Teste de Mann-Whitney. Resultados - De acordo com a avaliação nutricional 19 (61,3%) estavam com desnutrição e 12 (38,7%) com sobrepeso. Em relação à gravidade da doença 12 (39%) foram classificados como Child A, 17 (55%), Child B e 2 (6%) Child C, sendo 46,9% dos pacientes com o escore MELD >17. Na análise dos oligoelementos 31 (100%) apresentaram níveis de Mn acima dos valores de referência, 23 (74,2%) níveis baixos de Cu, 29 (93,5%) com deficiência de Se, e 31 (100%) níveis baixos de Ca e Mg. Em relação à gravidade da doença não houve diferença estatística entre os oligoelementos estudados, já em relação ao estado nutricional o grupo desnutrido apresentou níveis maiores de Mn (P=0,01) e Fe (P=0,01) e níveis diminuídos de Zn (P=0,03) quando comparado ao grupo sobrepeso. Conclusão - Os resultados mostraram que os oligoelementos estão alterados na doença hepática crônica, sem associação significativa com a gravidade da doença, mas sim com o estado nutricional. A desnutrição está presente nos pacientes estudados, porém um novo cenário com aumento na prevalência de sobrepeso foi verificado independente do grau de descompensação hepática.

We report here the genome sequence of Zika virus, strain ZikaSPH2015, containing all structural and nonstructural proteins flanked by the 5' and 3' untranslated region. It was isolated in São Paulo state, Brazil, in 2015, from a patient who received a blood transfusion from an asymptomatic donor at the time of donation.
