Immune-mediated hepatitis: Basic concepts and treatment.

Immunotherapy with immune checkpoint inhibitors (ICIs) has revolutionized advanced cancer management. Nevertheless, the generalized use of these medications has led to an increase in the incidence of adverse immune-mediated events and the liver is one of the most frequently affected organs. Liver involvement associated with the administration of immunotherapy is known as immune-mediated hepatitis (IMH), whose incidence and clinical characteristics have been described by different authors. It often presents as mild elevations of amino transferase levels, seen in routine blood tests, that spontaneously return to normal, but it can also manifest as severe transaminitis, possibly leading to the permanent discontinuation of treatment. The aim of the following review was to describe the most up-to-date concepts regarding the epidemiology, diagnosis, risk factors, and progression of IMH, as well as its incidence in different types of common cancers, including hepatocellular carcinoma. Treatment recommendations according to the most current guidelines are also provided.

Could Herpesviridae be the cause of severe acute hepatitis of unknown origin in children?

INTRODUCTION: Severe acute hepatitis (SAH) is defined by a severe inflammation of hepatocytes in the liver parenchyma which can lead to an acute liver failure, a clinical condition with high mortality rate that can be triggered by several factors but is usually associated to hepatotropic viruses' infection. In 2022, cases of children with severe acute hepatitis of unknown origin hospitalized in Glasgow, Scotland, were reported. Possible causes of this condition include, but are not limited to, undiagnosed viral (and non-viral) infections, autoimmune hepatitis, drug and/or chemical toxicity, mitochondrial chain respiratory and metabolic disorders. AREAS COVERED: Herpesviruses can cause severe acute hepatitis, but little is known about the role and the mechanisms of herpesviruses as a causative agent of this type of hepatitis. We review the role of herpesviruses as causative agent of SAH in children and other possible mechanisms involved in this disease. EXPERT OPINION: Differential diagnosis for herpesvirus in SAH should be implemented in all settings. Alternative fluids, such as saliva and dried blood, could be used in the diagnosis to overwhelm the availability of biological specimens at sufficient volume. In the future, genetic studies could also be added to increase the knowledge about severe acute hepatitis in children.

Boletín epidemiológico semana 29: Hepatitis / Epidemiological bulletin week 29: Hepatitis

Se estima que 1,3 millones de personas murieron a causa de hepatitis viral B y C crónica en 2022, es decir, 3 500 muertes por día; se calcula que 254 millones de personas viven con hepatitis B, 50 millones de personas viven con hepatitis C en todo el mundo y 6 000 personas se infectaron con hepatitis viral cada día. En numerosos países, muchas personas siguen sin ser diagnosticadas e incluso cuando se diagnostica la hepatitis, el número de personas que reciben tratamiento sigue siendo increíblemente bajo (1). A nivel mundial la incidencia del virus de la hepatitis B se calcula en 16 casos por 100 000 habitantes, de los cuales el 13,4 % viven con el virus de la hepatitis B crónico diagnosticado y el 2,6 % viven con el virus crónico tratado. La incidencia del virus de la hepatitis C se calcula en 13 casos por 100 000 habitantes, de los cuales el 36,4 % viven con el virus crónico diagnosticado y el 20 % viven con el virus crónico tratado (1, 2) En china se reportan diagnósticos y tratamiento del virus de la hepatitis B de 22 % y 15 %, respectivamente.

An estimated 1.3 million people died from viral hepatitis B and chronic C in 2022, that is, 3,500 deaths per day; It is estimated that 254 million people live with hepatitis B, 50 million people live with hepatitis C worldwide and 6,000 people were infected with hepatitis viral every day. In many countries, many people remain undiagnosed and even when hepatitis is diagnosed, the number of people receiving treatment remains incredibly low (1). Worldwide, the incidence of hepatitis B virus is estimated at 16 cases per 100,000. inhabitants, of which 13.4% live with chronic hepatitis B virus diagnosed and 2.6% live with the chronically treated virus. The incidence of hepatitis C virus is estimated at 13 cases per 100,000 inhabitants, of which of which 36.4% live with the diagnosed chronic virus and 20% live with the chronic virus treated (1, 2) In China, hepatitis B virus diagnoses and treatment are reported to be 22% and 15%, respectively.

Hepatobiliary disease after bone marrow transplant: A cross-sectional study of 377 patients.

BACKGROUND: Bone marrow transplantation (BMT) is a standard treatment for several haematologic conditions. Following BMT, patients may develop hepatobiliary complications that impact morbidity and mortality. The differential diagnosis may include drug-induced liver injury (DILI), sepsis-associated liver injury (SALI), sinusoidal obstruction syndrome (SOS), graft-versus-host disease (GVHD), viral hepatitis, ischaemic hepatitis, and fulminant hepatitis. AIMS: To evaluate the frequency, clinical characteristics, and outcomes of patients with hepatobiliary alterations associated with BMT in a tertiary referral centre. METHODS: This was a cross-sectional study with data collected from the medical records of patients undergoing BMT between January 2017 and June 2022. We diagnosed hepatobiliary complications based on established criteria. RESULTS: We included 377 patients; 55.7% had hepatobiliary complications. Female gender, pre-BMT hepatobiliary alteration, and haploidentical allogeneic transplantation were associated with increased risk with odds ratios (OR) of 1.8 (p = 0.005), 1.72 (p = 0.013) and 3.25 (p = 0.003), respectively. Patients with hepatobiliary complications spent longer in the hospital than those without (27.7 × 19.3 days, respectively; p < 0.001). Among 210 patients with hepatobiliary complications, 28 died compared to 5 of 167 without complications (OR 4.98; p = 0.001). CONCLUSIONS: Hepatobiliary complications are frequent in patients undergoing BMT. There is a greater risk of their occurrence in women, people with pre-BMT liver alterations, and in haploidentical transplants. The occurrence of these complications increases the length of stay and is associated with a higher risk of death.

[Síndrome hemofagocítico linfohistiocitario secundario a Dengue en una paciente de 6 años: reporte de caso].

Background: Dengue fever is a mosquito-borne infectious disease endemic in over 100 countries around the world. Among the complications that dengue can cause the Hemophagocytic Lymphohistiocytosis is one of great concern for its severity and complex diagnosis. Case report: Hereby we document a case of this disease expressed on a previously healthy 6-year-old female patient whose dengue infection was so severe that needed intensive care management with vasoactive drugs and diuretics. After a short period of wellness began newly with fever, pancytopenia, hepatitis, and inflammatory response symptoms. Conclusions: A Dengue associated Hemophagocytic Lymphohistiocytosis syndrome was suspected and treated with intravenous corticosteroids on a 3-day scheme at no signs of malignancy with excellent response. The health care professionals must know about this not novel entity in order to reach an efficient diagnosis and treatment mostly, but not only, those in tropical and sub-tropical regions of the word were dengue virus is endemic.

Antecedentes: La fiebre por dengue es una enfermedad infecciosa transmitida por mosquitos, endémica en más de 100 países alrededor del mundo. La Linfohistiocitosis Hemofagocítica, dentro de las complicaciones que puede ocasionar el dengue, es una de las más preocupantes por su complejidad diagnostica y gravedad. Reporte de caso: Femenino de 6 años de edad, previamente sana, cuya infección por dengue fue tan grave que requirió manejo en cuidados intensivos. Después de un breve período de bienestar recrudeció la fiebre, además de pancitopenia, hepatitis y síntomas de respuesta inflamatoria. Conclusiones: Se sospechó síndrome de Linfohistiocitosis Hemofagocítica asociada a Dengue y se trató con corticoides intravenosos en un esquema de 3 días con excelente respuesta. Los profesionales de la salud deben conocer esta entidad no novedosa para poder llegar a un diagnóstico y tratamiento eficaz en su mayoría, pero no solo, en las regiones tropicales y subtropicales del mundo donde el virus del dengue es endémico.

ß-Blockers in Hepatosplenic Schistosomiasis: A Narrative Review.

Hepatosplenic schistosomiasis (HSS) is a serious complication of chronic schistosomiasis that can result in portal hypertension and variceal bleeding. ß-blockers, a class of medications commonly used to treat hypertension and other cardiovascular conditions, have been investigated for their potential use in preventing variceal bleeding in HSS. Several studies have shown that ß-blockers can reduce portal pressure and prevent variceal bleeding effectively in these patients. However, there are limited data on the long-term efficacy and safety of ß-blockers in this setting, and further research is needed to determine the optimal use of these medications. This review summarizes the evidence supporting current recommendations of ß-blocker use in patients with HSS.

Fatal Simplexvirus humanalpha1 infection in howler-monkeys (Alouatta sp.) under human care: Clinical, molecular, and pathological findings.

BACKGROUND: Simplexvirus humanalpha1 (HuAHV-1) are common anthropozoonosis reported in marmosets but rare in howler monkeys (Alouatta sp.). METHODS: Necropsy of two brown-howler monkeys (A. caraya) and one red-howler monkey (A. guariba clamitans) from different zoo collections were performed. Fragments of all organs were examined through microscopy. Samples were submitted to IHC for Simplexvirus humanalpha 2 (HuAHV-2) [sin. Herpesvirus simplex type 2] and PCR. RESULTS: Grossly, only the A. guariba showed liver lesions characterized by multifocal, pinpoint white areas corresponding microscopically as random necrotizing herpetic hepatitis and ulcerative glossitis. Both A. caraya showed necrotizing meningoencephalitis with Cowdry A-type body inclusions within neurons and astrocytes. Immunolabeling for HuAHV-1/2 was observed in the tongue, liver, and brain. HuAHV-1 was confirmed in all samples by PCR, Sanger sequencing, and phylogenetic analyses. CONCLUSION: Necrotizing meningoencephalitis was appreciated in 2/3 of animals, and it is associated with neurologic signs. Along with ulcerative glossitis, a hallmark lesion in marmosets, it was present in one animal. Regarding herpetic hepatitis, it is not frequent in monkeys and occurs mainly in immunocompromised animals. HuAHV-1 infection was confirmed corroborating with a human source. This is the second report on captive black-howler monkeys and the first gross, histologic, immunohistochemical, and molecular description of herpetic hepatitis and ulcerative glossitis in red-howler monkeys (A. guariba).

Serum soluble mediators as prognostic biomarkers for morbidity, disease outcome, and late-relapsing hepatitis in yellow fever patients.

This study described a soluble mediator storm in acute Yellow Fever/YF infection along the kinetics timeline towards convalescent disease. The analyses of the YF Viral RNAnemia, chemokines, cytokines, and growth factors were performed in YF patients at acute/(D1-15) and convalescent/(D16-315) phases. Patients with acute YF infection displayed a trimodal viremia profile spreading along D3, D6, and D8-14. A massive storm of mediators was observed in acute YF. Higher levels of mediators were observed in YF with higher morbidity scores, patients under intensive care, and those progressing to death than in YF patients who progress to late-relapsing hepatitis/L-Hep. A unimodal peak of biomarkers around D4-6 with a progressive decrease towards D181-315 was observed in non-L-Hep patients, while a bimodal pattern with a second peak around D61-90 was associated with L-Hep. This study provided a comprehensive landscape of evidence that distinct immune responses drive pathogenesis, disease progression, and L-Hep in YF patients.

Characterization and Investigation of Risk Factors for Late-Relapsing Hepatitis After Yellow Fever.

BACKGROUND: Late-relapsing hepatitis after yellow fever (LHep-YF) during the convalescent phase of the disease has been described during recent yellow fever (YF) outbreaks in Brazil. LHep-YF is marked by a rebound in liver enzymes and nonspecific clinical manifestations around 46-60 days after YF symptom onset. METHODS: Here we have characterized the clinical course and risk factors for LHep-YF using data from a representative cohort of patients who survived YF in Brazil, 2017-2018. A total of 221 YF-positive patients were discharged from the infectious disease reference hospital in Minas Gerais and were followed up at 30, 45, and 60 days post-symptom onset. RESULTS: From 46 to 60 days post-symptom onset, 16% of YF patients (n = 36/221) exhibited a rebound of aminotransferases (aspartate aminotransferase or alanine aminotransferase >500 IU/L), alkaline phosphatase, and total bilirubin levels. Other etiologies of liver inflammation such as infectious hepatitis, autoimmune hepatitis, and metabolic liver disease were ruled out. Jaundice, fatigue, headache, and low platelet levels were associated with LHep-YF. Demographic factors, clinical manifestations, laboratory tests, ultrasound findings, and viral load during the acute phase of YF were not associated with the occurrence of LHep-YF. CONCLUSIONS: These findings provide new data on the clinical course of Late-relapsing hepatitis during the convalescent phase of YF and highlight the need for extended patient follow-up after acute YF.

Recent Increase in Incidence of Severe Acute Hepatitis of Unknown Etiology in Children is Associated with Infection with Adenovirus and Other Nonhepatotropic Viruses.

OBJECTIVE: To evaluate whether the nature and severity of non-A-E severe acute hepatitis in children noted by the World Health Organization from late 2021 through early 2022 was indeed increased in 2021-2022 compared with prior years. STUDY DESIGN: We performed a single-center, retrospective study to track the etiology and outcomes of children with non-A-E severe acute hepatitis in 2021-2022 compared with the prior 3-year periods (2018-2019, 2019-2020, and 2020-2021). We queried electronic medical records of children ≤16 years of age with alanine or aspartate aminotransferase levels of >500 IU. Data were analyzed for the periods of October 1, 2021, to May 1, 2022, and compared with the same time periods in 2018-2021. RESULTS: Of 107 children meeting entry criteria, 82 cases occurred from October to May of 2018-2022. The average annual case number was 16.3 in 2018-2021 compared with a 2-fold increase (to 33) in 2021-2022 (P = .0054). Analyses of etiologies showed that this increase was associated with a higher number of children who tested positive for viruses (n = 16) when compared with the average of 3.7 for 2018-2021 (P = .018). Adenovirus (26.1%) and severe acute respiratory syndrome coronavirus-2 (10.3%) were the most frequently detected viruses in 2021-2022. Despite evidence of acute liver failure in 37.8% of children in the entire cohort and in 47% of those with viral infection, the overall survival rate was high at 91.4% and 88.9%, respectively. CONCLUSIONS: The number of children with severe acute hepatitis in our center increased from 2021 to May 2022, with a greater frequency of cases associated with adenovirus, yet transplant-free survival remains high.

Shunt portosistémico, una causa poco frecuente de hepatitis colestásica en neonatología. A propósito de un caso / Portosystemic shunt, a rare cause of neonatal cholestatic hepatitis. A case report

El shunt portosistémico congénito es una anomalía vascular venosa que comunica circulación portal y sistémica, por la que se deriva el flujo sanguíneo, salteando el paso hepático. Es una entidad poco frecuente, cuya incidencia varía entre 1/30 000 y 1/50 000 recién nacidos. Puede cursar de forma asintomática o presentarse con complicaciones en la edad pediátrica o, menos frecuente, en la edad neonatal. Ante el diagnóstico, se deberá definir la necesidad de intervención quirúrgica o intravascular para el cierre. Esta decisión depende de las características anatómicas de la malformación, de las manifestaciones clínicas y complicaciones presentes. Se presenta el caso de un paciente de un mes de vida derivado a nuestro centro para estudio de hepatitis colestásica neonatal, con diagnóstico de shunt portosistémico extrahepático. Se realizó cierre intravascular de la lesión con mejoría significativa posterior.

Congenital portosystemic shunt is a venous vascular abnormality that connects portal and systemic circulation, resulting in diversion of the blood flow, bypassing the hepatic passage. It is a rare malformation; its incidence varies from 1:30 000 to 1:50 000 newborns. It may be asymptomatic or present with complications in the pediatric age or, less frequently, in the neonatal age. Upon diagnosis, the need for a surgical or an intravascular intervention for closure should be defined. This decision depends on the malformation anatomical characteristics, clinical manifestations, and complications. We present the case of a 1-month-old patient referred to our center for the study of neonatal cholestatic hepatitis, with a diagnosis of extrahepatic portosystemic shunt. Intravascular closure of the defect was performed with significant subsequent improvement.

Fibroblast Activation Protein Activates Macrophages and Promotes Parenchymal Liver Inflammation and Fibrosis.

BACKGROUND & AIMS: Fibroblast activation protein (FAP) is expressed on activated fibroblast. Its role in fibrosis and desmoplasia is controversial, and data on pharmacological FAP inhibition are lacking. We aimed to better define the role of FAP in liver fibrosis in vivo and in vitro. METHODS: FAP expression was analyzed in mice and patients with fibrotic liver diseases of various etiologies. Fibrotic mice received a specific FAP inhibitor (FAPi) at 2 doses orally for 2 weeks during parenchymal fibrosis progression (6 weeks of carbon tetrachloride) and regression (2 weeks off carbon tetrachloride), and with biliary fibrosis (Mdr2-/-). Recombinant FAP was added to (co-)cultures of hepatic stellate cells (HSC), fibroblasts, and macrophages. Fibrosis- and inflammation-related parameters were determined biochemically, by quantitative immunohistochemistry, polymerase chain reaction, and transcriptomics. RESULTS: FAP+ fibroblasts/HSCs were α-smooth muscle actin (α-SMA)-negative and located at interfaces of fibrotic septa next to macrophages in murine and human livers. In parenchymal fibrosis, FAPi reduced collagen area, liver collagen content, α-SMA+ myofibroblasts, M2-type macrophages, serum alanine transaminase and aspartate aminotransferase, key fibrogenesis-related transcripts, and increased hepatocyte proliferation 10-fold. During regression, FAP was suppressed, and FAPi was ineffective. FAPi less potently inhibited biliary fibrosis. In vitro, FAP small interfering RNA reduced HSC α-SMA expression and collagen production, and FAPi suppressed their activation and proliferation. Compared with untreated macrophages, FAPi regulated macrophage profibrogenic activation and transcriptome, and their conditioned medium attenuated HSC activation, which was increased with addition of recombinant FAP. CONCLUSIONS: Pharmacological FAP inhibition attenuates inflammation-predominant liver fibrosis. FAP is expressed on subsets of activated fibroblasts/HSC and promotes both macrophage and HSC profibrogenic activity in liver fibrosis.

Avaliação do perfil epidemiológico das hepatites virais no Brasil - 2010 A 2021 / Evaluation of the epidemiological profile of viral hepatitis in Brazil - 2010 to 2021

As hepatites virais são doenças que apresentam elevado impacto de morbimortalidade no mundo, sendo assim, consideradas um grave problema para a saúde pública. Nos últimos anos o enfrentamento das hepatites virais tem sido um grande desafio, principalmente para os países com alta prevalência de vulnerabilidades sociais. Medidas de controle e prevenção da doença devem ser tomadas, por isso torna-se necessário a realização de estudos que contemplem conhecimentos sobre a dinâmica epidemiológica das hepatites para demonstrar sua importância em relação a saúde pública. Objetivo: O objetivo nesta pesquisa foi analisar o perfil epidemiológico das hepatites virais no Brasil, no período de 2010 a 2021. Método: Realizou-se um estudo transversal, descritivo, retrospectivo e qualiquantitativo que utilizou como unidades de análise as unidades federativas brasileiras. Os dados foram coletados a partir das informações disponíveis no site TABNET/DATASUS, DCCI, e a estimativa da população anual absoluta foi obtida no Instituto Brasileiro de Geografia e Estatística (IBGE). Resultados: No período analisado foram registrados 476.981 casos de hepatites virais no Brasil, destacando-se a notificação de casos de hepatite C, seguida pela hepatite B, A e D. Com relação a taxa de incidência, a Região Norte destacou-se para hepatite A e D, e a Região Sudeste para hepatite B e C. O sexo do indivíduo acometido em todos os tipos de hepatite virais analisados que se destacou foi o masculino, mas com pouca diferença do feminino. Foram registrados 25.553 óbitos, sendo 78,3% devido à hepatite C. A presente pesquisa nos permitiu concluir que o tipo de hepatite mais relatada no Brasil é a tipo C, assim como a que mais provoca óbitos. Todas as hepatites virais apresentaram queda nas notificações no ano de 2020 e 2021 e por isso este fato deve ser analisado pelos setores de vigilância pois pode se tratar de subnotificações, principalmente devido a situação do país neste período, que enfrentava a pandemia de COVID-19

Viral hepatitis is a disease with a high impact on morbidity and mortality worldwide and hence considered a serious problem for public health. Fighting viral hepatitis has been a major challenge in recent years, especially for countries with a high prevalence of social vulnerabilities. Measures to control and prevent the disease must therefore be taken, so studies that include knowledge about the epidemiological dynamics of hepatitis are warranted to demonstrate its importance to public health. In the objective of the present study was to analyze the epidemiological profile of viral hepatitis in Brazil in the period from 2010 to 2021. A cross-sectional, descriptive, retrospective, and qualitative-quantitative investigation was carried out using the federative units of Brazil as units of analysis. Data were collected from information available on the TABNET/DATASUS, DCCI website, and the absolute annual population estimate was obtained from the Brazilian Institute of Geography and Statistics (IBGE). In the analyzed period, 476,981 cases of viral hepatitis were recorded in Brazil, the majority of which referred to hepatitis C, followed by hepatitis B, A, and D. As regards the incidence rate, the north region stood out with hepatitis A and D; and the southeast region with hepatitis B and C. Males prevailed between the genders of individuals affected, considering all types of viral hepatitis analyzed, but with little difference from females. A total of 25,553 deaths were recorded, 78.3% of which were due to hepatitis C. Conclusions: The present study allowed us to conclude that the most reported type of hepatitis in Brazil is type C, which is also the most death-causing. There was a drop in notifications of all viral hepatitis in 2020 and 2021, and this fact should be analyzed by surveillance sectors as it may be a situation of underreporting, due mainly to the COVID-19 pandemic crisis the country was facing in the period
