Una visión integral del manejo de la hepatitis C y el objetivo de erradicarla / A comprehensive view of hepatitis C management and the goal of eradication

La hepatitis C es una enfermedad viral causada por el virus de la hepatitis C (VHC), que fue identificada por primera vez en 1989 por un equipo de científicos liderado por Michael Houghton en Chiron Corporation. Esta forma de hepatitis era conocida como "hepatitis no-A no-B", ya que no se podía identificar el agente infeccioso responsable. Puede afectar a personas de diferentes géneros y orientaciones sexuales, incluidos los hombres que tienen sexo con hombres (HSH); y su transmisión ocurre a través de situaciones en las que hay un intercambio de sangre, como el uso compartido de agujas o equipo para la inyección de drogas, o durante prácticas sexuales que pueden causar microlesiones en la mucosa anal. Es importante destacar que la hepatitis C también puede transmitirse a través de otras vías, como la transfusión de sangre no segura, la exposición a instrumentos médicos contaminados, o el compartir objetos personales que puedan tener sangre infectada.

Hepatitis C is a viral disease caused by the hepatitis C virus (HCV), which was first identified in 1989 by a team of scientists led by Michael Houghton at Chiron Corporation. This form of hepatitis was known as "non-A non-B hepatitis" as the infectious agent responsible couldn't be identified. It can affect individuals of different genders and sexual orientations, including men who have sex with men (MSM); transmission occurs through situations involving blood exchange, such as needle sharing or equipment for drug injection, or during sexual practices that may cause microlesions in the anal mucosa. It's important to note that hepatitis C can also be transmitted through other routes, such as unsafe blood transfusion, exposure to contaminated medical instruments, or sharing personal items that may have infected blood.

Antivirales de acción directa contra la hepatitis C: revisión narrativa / Direct acting antivirals against hepatitis C: Literature review

Desde los años ochenta se ha explorado el tratamiento para el virus de la hepatitis C, aunque en ese entonces los medicamentos disponibles eran poco toleradas y poco eficaces. En el 2011, la introducción de antivirales de acción directa transformó significativamente el curso de la enfermedad, logrando tasas de curación superiores al 90 % en los pacientes. Este avance ha permitido prevenir complicaciones futuras con efectos adversos mínimos. La presente revisión aborda la línea de tiempo del descubrimiento de los antivirales, su mecanismo de acción, sus indicaciones y potencial impacto en la salud pública.

Since the 1980s, the treatment of hepatitis C has been explored, although at that time, the available medications were poorly tolerated and ineffective. In 2011, the introduction of direct-acting antivirals significantly transformed the course of the disease, achieving cure rates of over 90% in patients. This advance has made it possible to prevent future complications with minimal adverse effects. This review addresses the timeline of the discovery of antivirals, their mechanism of action, and their impact on medicine.

Daño hepático inducido por uso de anticonceptivos orales en una paciente con ictericia prolongada y transaminasas elevadas: reporte de caso / Drug-induced liver injury secondary to the use of oral contraceptives in a patient with prolonged jaundice and elevated transaminases: Case report

La hepatotoxicidad inducida por medicamentos es un diagnóstico de descarte. Típicamente, se presenta en pacientes que desarrollan cambios clínicos y bioquímicos compatibles con hepatitis, pero relacionados con el inicio reciente de agentes farmacológicos, y que se resuelven tras el retiro de la noxa. Su desarrollo se ha descrito con el uso de algunos antibióticos, antituberculosos, estatinas, herbolarios y antiinflamatorios no esteroideos; sin embargo, hay pocos reportes de casos con el uso de anticonceptivos orales, en los cuales el surgimiento de mecanismos idiosincráticos puede llevar a la presentación de características clínicas como ictericia y anormalidades en los exámenes de laboratorio, como la elevación de las transaminasas. Esto requiere de estudios extensos para descartar otras patologías que pueden presentarse de esta forma, lo que representa un reto clínico. En este artículo se muestra el reporte de un caso de una paciente con antecedente de uso crónico de anticonceptivos implantables y que, tras el ajuste de la terapia con el inicio de anticonceptivos orales, desarrolla un episodio de elevación marcada de transaminasas e ictericia.

Drug-induced liver injury is a rule-out diagnosis. Typically, it occurs in patients who develop clinical and biochemical changes compatible with hepatitis, but related to a history of recent onset of pharmacological agents, and resolves after withdrawal of the noxious substances. Its development has been described with the use of some antibiotics, antituberculosis agents, statins, herbal and nonsteroidal anti inflammatory drugs; however, there are few reports of cases with the use of oral contraceptives, in which the appearance of idiosyncratic mechanisms can lead to the presentation of clinical features such as jaundice and laboratory tests abnormalities, like transaminase elevation, requiring extensive studies to rule out other pathologies that may have this clinical presentation, wich represents a clinical challenge. We present a case report of a patient who had chronic use of implantable contraceptives and who, after adjustment of therapy with the start of oral contraceptives, developed an episode of marked elevation of transaminases and jaundice.

Lesión hepática inducida por Phyllanthus niruri (chancapiedra), un remedio natural para urolitiasis / Liver injury induced by Phyllanthus niruri (chancapiedra), a natural remedy for urolithiasis

Tanto la lesión hepática inducida por drogas (DILI), así como la lesión hepática inducida por hierbas (HILI), son una preocupación creciente en la atención sanitaria contemporánea que plantea importantes desafíos clínicos debido a sus variadas etiologías, presentaciones clínicas y posibles resultados potencialmente mortales. Presentamos el caso de un paciente masculino de 38 años con antecedentes de cálculos renales que consultó por dolor lumbar y hematuria. Al ingreso presentó ictericia, hepatomegalia, dolor a la palpación en fosa ilíaca derecha y no tenía signos de hepatopatía crónica, con pruebas de función hepática anormales, que mostraron un patrón hepatocelular asociado con hiperbilirrubinemia. Se descartó obstrucción biliar, trombosis portal, hepatitis autoinmune y viral, con panel autoinmune negativo. El paciente refirió haber consumido un remedio herbario para los cálculos renales llamado "vino rompe cálculos (chancapiedra)", que se supone contiene Phyllanthus niruri, cinco días antes del inicio de los síntomas. Una biopsia hepática reveló hepatitis aguda con infiltrado inflamatorio mixto. Debido al empeoramiento de las pruebas de función hepática y la sospecha de DILI idiosincrásico, se inició un ensayo terapéutico con corticosteroides, que resultó en una mejoría clínica y del perfil hepático. La gravedad de este caso nos recuerda la necesidad de incrementar el seguimiento por parte de las autoridades reguladoras de medicamentos, implementar campañas educativas para los pacientes e informar a la comunidad sobre productos con alertas activas.

Both drug-induced liver injury (DILI) and herb-induced liver injury (HILI) are a growing concern in contemporary healthcare that poses significant clinical challenges due to their varied etiology, clinical presentations, and potential life-threatening outcomes. We present the case of a 38-year-old male patient with a history of kidney stones who consulted for low back pain and hematuria. On admission he presented with jaundice, hepatomegaly, pain on palpation in the right iliac fossa and no signs of chronic liver disease, with abnormal liver function tests, which showed a hepatocellular pattern associated with hyperbilirubinemia. Biliary obstruction, portal thrombosis, autoimmune and viral hepatitis were ruled out, with negative autoimmune panel. The patient reported consuming an herbal remedy for kidney stones called "stone-breaking wine (chancapiedra)", presumed to contain Phyllanthus niruri, five days before the onset of symptoms. A liver biopsy revealedacute hepatitis with mixed inflammatory infiltrate. Due to worsening liver function tests and suspicion of idiosyncratic DILI, a therapeutic trial with corticosteroids was initiated, which resulted in clinical and liver profile improvement. The severity of this case reminds us of the need to increase follow-up by drug regulatory authorities, implement educational campaigns for patients, and inform the community about products with active alerts.

Orbital mucosa-associated lymphoid tissue (MALT) lymphoma as the initial presentation in patients with hepatitis C virus infection

ABSTRACT Hepatitis C virus infection may be implicated in 12.7% of ocular adnexal marginal zone lymphomas. We present the first case of an orbital-systemic mucosa-associated lymphoid tissue lymphoma that responded to hepatitis C virus medical treatment. A 62-year-old male with a right-sided orbital mass was diagnosed with stage IIA orbital marginal zone lymphoma in addition to hepatitis C virus infection based on clinical, imaging, laboratory, and histological examinations. The systemic and orbital responses were achieved 1 year after undergoing hepatitis C virus treatment with glecaprevir/pibrentasvir. The association between the hepatitis C virus infection and orbital-systemic mucosa-associated lymphoid tissue lymphoma is relevant. Accordingly, patients with orbital mucosa-associated lymphoid tissue lymphoma should be assessed for hepatitis C virus seroreactivity for therapeutic and prognostic purposes.

Prevalence and clinical consequences of Hepatitis C virus infection in patients undergoing hematopoietic stem cell transplantation

ABSTRACT Hepatitis C virus (HCV) infection is a significant cause of morbidity and mortality among hematopoietic stem cell transplant (HCT) recipients. In Brazil, its occurrence in HCT recipients remains undetermined. We now report on HCV prevalence in HCT recipients and its clinical consequences. The medical records of all HCT recipients seen at Hospital das Clinicas, Sao Paulo University Medical School, from January 2010 to January 2020 were reviewed to determine HCV serostatus. A retrospective analysis of medical charts was undertaken on all seropositive cases to determine HCV genotype, presence of liver fibrosis, co-infections with other viruses, previous treatments, and clinical evolution of liver pathology after HCT. Of the 1,293 HCT recipients included in the study, seven (0.54%) were HCV antibody-positive and five (0.39%) were also viremic for HCV-RNA. Four of these individuals had moderate to severe liver fibrosis (METAVIR F2/F3) and one was cirrhotic. Two of the viremic patients developed acute liver dysfunction following transplantation. All patients had their acute episode of liver dysfunction resolved with no further complications. Four of the viremic patients were treated for HCV infection with direct acting agents (DAA). Information regarding HCV treatment was lacking for one of the viremic HCV patients due to loss of follow up. Sustained anti-virologic responses were observed in three cases after the use of DAA. The detection of HCV in hematological adults undergoing HCT and its successful treatment with DAA highlight the necessity of testing for HCV both prior to and following transplantation.

Could a reduced hemoglobin, albumin, lymphocyte, and platelet (HALP) score predict autoimmune hepatitis and degree of liver fibrosis?

SUMMARY OBJECTIVE: Autoimmune hepatitis is a rare inflammatory disease of the liver that is characterized by elevated liver enzymes. The hemoglobin, albumin, lymphocyte, and platelet score, which is derived from hemoglobin, serum albumin, circulating lymphocyte count, and platelet count, is also associated with inflammatory conditions. The aim was to examine the hemoglobin, albumin, lymphocyte, and platelet score of patients with autoimmune hepatitis and to compare it to that of healthy individuals in this retrospective analysis. METHODS: Subjects diagnosed with autoimmune hepatitis were enrolled in the study, and healthy individuals were enrolled as controls. Moreover, autoimmune hepatitis subjects were grouped into mild or moderate/advanced fibrosis. Furthermore, aspartate to platelet ratio index, Fibrosis-4, and hemoglobin, albumin, lymphocyte, and platelet scores of the autoimmune hepatitis patients and controls were compared. In addition, the hemoglobin, albumin, lymphocyte, and platelet score of the autoimmune hepatitis patients with mild fibrosis is compared to that of those with moderate/advanced fibrosis. RESULTS: The mean hemoglobin, albumin, lymphocyte, and platelet score of the autoimmune hepatitis patients was 44.2±14.5 while this value was 76.8±15.5 in control subjects. The hemoglobin, albumin, lymphocyte, and platelet score was significantly reduced in autoimmune hepatitis patients than healthy controls (p<0.001). The hemoglobin, albumin, lymphocyte, and platelet score was significantly and negatively correlated with C-reactive protein, aspartate, alanine transaminase, gamma glutamyl transferase, aspartate to platelet ratio index, and Fibrosis-4 values. A hemoglobin, albumin, lymphocyte, and platelet score that was lower than 52.3 had 83% sensitivity and 73% specificity in predicting autoimmune hepatitis. The sensitivity and specificity of the hemoglobin, albumin, lymphocyte, and platelet score were higher than the Fibrosis-4 score in predicting moderate/advanced fibrosis in autoimmune hepatitis. CONCLUSION: We suggest that the hemoglobin, albumin, lymphocyte, and platelet score be used as an additional noninvasive diagnostic tool for autoimmune hepatitis and to predict moderate/advanced liver fibrosis in patients with autoimmune hepatitis.

Lack of evidence of acute HEV infections as a sexually transmitted disease: Data from a German cohort of PrEP users

Abstract Background While the sexual transmissibility of HAV in MSM has been extensively described, the potential for sexual transmission of HEV has not been definitively established. Although HEV has been detected in the ejaculate of chronically infected men, studies among MSM PrEP users in France did not observe an elevated anti-HEV seroprevalence as an indicator of increased exposure risk by sexual intercourse. Patients and methods A total of 111 unselected PrEP users and 111 age- and sex-matched blood donors were tested for anti-HEV IgG, IgM and HEV (PCR). Of the participants 79/111 (71 %) responded to a questionnaire covering topics as sexual preferences, previous sexually transmitted diseases, profession, food consumption, and pet ownership. Results The anti-HEV IgG seroprevalence in PrEP users (22 %) did not differ significantly from the rate in controls (17 %). While one PrEP user and three controls tested positive for anti-HEV IgM, all PrEP users and controls tested PCR negative. Conclusion In immunocompetent individuals with frequent changes of sexual partners, the epidemiology of Hepatitis E Virus does not significantly involve the sexual transmission route.

Independent predictors for non-alcoholic fatty liver disease in patients with treatment-naïve chronic hepatitis B

SUMMARY OBJECTIVE: There are limited data on non-alcoholic fatty liver disease in chronic hepatitis B virus infection. We aimed to determine the predictors for non-alcoholic fatty liver disease in patients with treatment-naïve chronic hepatitis B virus infection. METHODS: All consecutive treatment-naïve patients with chronic hepatitis B virus infection at the Haseki Training and Research Hospital between October 1, 2021, and September 31, 2022, were retrospectively enrolled. Chronic hepatitis B virus infection is defined by positive serum hepatitis B surface antigen for 6 months or more. Patients with significant alcohol consumption, prolonged steatogenic drug use, malignancy, monogenic hereditary disorders, patients co-infected with hepatitis D virus, hepatitis C virus infection, or human immunodeficiency virus were excluded. Demographic characteristics, anthropometric determinants, laboratory findings, and virological parameters were retrospectively collected from patients' charts and electronic medical records. RESULTS: A total of 457 patients with treatment-naïve chronic hepatitis B virus infection were included in the study. The three multivariate regression models revealed that age (p<0.028), body mass index (p=0.046), diabetes mellitus (p=0.030), hemoglobin (p=0.008), platelet (p=0.012), and triglyceride (p=0.002) in Model 1; body mass index (p=0.033), diabetes mellitus (p<0.001), hemoglobin (p=0.008), platelet (p=0.004), LDL (p=0.023), and HDL (p=0.020) in Model 2; and age (p<0.001), body mass index (p=0.033), hemoglobin (p=0.004), platelet (p=0.004), and HDL (p=0.007) in Model 3 were independent predictors. CONCLUSION: Non-alcoholic fatty liver disease was observed in about one-third of patients with chronic hepatitis B virus infection and was positively associated with older age, higher body mass index, presence of comorbid conditions including diabetes mellitus, increased levels of metabolic laboratory parameters, especially serum triglyceride and LDL, and decreased HDL.

Aspects that facilitate access to care for viral hepatitis: An evaluative research

ABSTRACT BACKGROUND: Viral hepatitis is a major public health concern worldwide. OBJECTIVES: This study aimed to analyze the factors that facilitate access to care for viral hepatitis. DESIGN AND SETTING: Using a sequential mixed method, this evaluation research was conducted in the state of Mato Grosso, Brazil. METHODS: Mapping of references and selection of regions were made based on the quantity and heterogeneity of services. The stakeholders, including the managers of the State Department of Health and professionals from reference services, were identified. Nine semi-structured interviews were conducted using content analysis and discussions guided by the dimensions of the analysis model of universal access to health services. RESULTS: In the political dimension, decentralizing services and adhering to the Intermunicipal Health Consortium are highly encouraged. In the economic-social dimension, a commitment exists to allocate public funds for the expansion of referral services and subsidies to support users in their travel for appointments, medications, and examinations. In the organizational dimension, the availability of inputs for testing, definition of user flow, ease of scheduling appointments, coordination by primary care in testing, collaboration following the guidelines and protocols, and engagement in extramural activities are guaranteed. In the technical dimension, professionals actively commit to the service and offer different opening hours, guarantee the presence of an infectious physician, expand training opportunities, and establish intersectoral partnerships. In the symbolic dimension, professionals actively listen to the experiences of users throughout their care trajectory and demonstrate empathy. CONCLUSIONS: The results are crucial for improving comprehensiveness, but necessitate managerial efforts to enhance regional governance.

Trends and spatial distribution of hepatitis B in pregnant women in Brazil / Tendência e distribuição espacial da hepatite B em gestantes no Brasil

Abstract Objectives: to analyze the trend and spatial distribution of hepatitis B in pregnant women in Brazil. Methods: ecological study based on all notified cases of hepatitis B in pregnant women through the Information System for Notifiable Diseases - Sinan between 2009 and 2018. Hepatitis B virus (HBV) detection rates were calculated in all municipalities. Spatial analysis was performed using the Global Moran Index for global data and local indicators of spatial association (Lisa) for the 5,570 municipalities. For trend analysis by State, the Prais-Winsten generalized linear regression model was used. Results: 15,253 pregnant women with HBV were reported. High detection rates were observed in the municipalities of São Miguel da Boa Vista-SC (68.96/1000 live births (LB)), Araguaiana-MT (68.18/1000 LB), Reserva do Cabaçal-MT (80, 00/1,000 LB), São Geraldo da Piedade-MG (75/1000 LB), Porto Mauá-RS (111, 11/1000 LB), in the respective bienniums. Moran (I) (I=0.056) showed a positive spatial association. In Lisa, 78 municipalities were included in the high-high cluster, 51.28% in the South region and 48 in the low-low cluster with 72.91% in the Southeast. There was an increasing trend in Maranhão (p=0.004) and Pernambuco (p=0.007) and a decrease in Mato Grosso (p=0.012), Paraná (p=0.031) and Santa Catarina (p=0.008). Conclusion: the detection of hepatitis B in pregnant women was observed in most Brazilian municipalities, with an increasing trend in two states and a decrease in three others.

Métodos: O estudo é transversal e utilizou dados do Banco de Olhos da Paraíba entre janeiro de 2013 e dezembro de 2022. Dados sobre procedência, idade, sexo, causa do óbito, tempo entre óbito e enucleação, resultados sorológicos e motivo de descarte das córneas dos doadores foram coletados. Resultados: O maior motivo de descarte foi por sorologia positiva (56,5%), sendo positivadas as sorologias positivas para hepatite B e HBsAg em 11,1% e 4,75% dos pacientes, respectivamente. Conclusão: A sorologia positiva para hepatite B como um critério de descarte absoluto é responsável por grande parcela de descartes, apesar da pouca informação sobre suas repercussões e representação de infectividade nos receptores do transplante.

ABSTRACT Objective: To identify the profile of human ocular tissue donors in the area covered by the Eye Bank of Paraíba (PB), highlighting the impact of positive serology for hepatitis B (anti-HBc) in the disposal of tissues for transplantation. Methods: This is a cross-sectional that uses data from the Eye Bank of Paraíba (PB) between January 2013 and December 2022. Data on origin, age, sex, cause of death, time between death and enucleation, serological results, and reason for discarded donor corneas were collected. Results: The main reason for discarding was due to positive serology (56.5%), with positive anti-HBc and HBsAg serology in 11.1% and 4.75% of patients, respectively. Conclusion: Anti-HBc positive serology as an absolute disposal criterion is responsible for great part of disposals, despite little information about its repercussions and representation of infectivity in transplant recipients.

Molecular genetic association of rs8099917 and rs1800795 polymorphisms in the progression of hepatitis Delta virus liver disease

Background: The relationship between viral infections and host factors holds high hopes for identifying the role of Interferon Lambda 3 (IFNL3) and Interleukin 6 (IL-6) polymorphisms in the development of Chronic Liver Disease (CLD) in patients infected with hepatitis Delta virus (HDV) in the Western Brazilian Amazon. Methods: Cross-sectional study conducted with a cohort of 40 chronic HDV patients, 27 with CLD and 13 without evident liver damage. Biological samples from the participants were analyzed using the polymerase chain reaction (PCR) technique, followed by sequencing by the automated Sanger method. Results: The rs8099917 T allele, from the IFNL3 gene, showed a higher frequency in both groups; however, it was not possible to establish an association with HDV infection [OR = 1.42 (0.42 - 4.75; p = 0.556 (95% CI). For IL-6, the rs1800795 G allele was superior to rs1800795 C. Analyzing both distributions in the studied groups, any association with HDV was absent (p > 0.05). Conclusion: The results suggest that the rs8099917 T/G (IFNL3) and rs1800795 G/C (IL-6) polymorphisms are not associated with the evolution of HDV in the studied population.

Infections in the era of immunobiologicals

Abstract Immunobiologicals represent an innovative therapeutic option in dermatology. They are indicated in severe and refractory cases of different diseases when there is contraindication, intolerance, or failure of conventional systemic therapy and in cases with significant impairment of patient quality of life. The main immunobiologicals used in dermatology basically include inhibitors of tumor necrosis factor-alpha (anti-TNF), inhibitors of interleukin-12 and -23 (anti-IL12/23), inhibitors of interleukin-17 and its receptor (anti-IL17), inhibitors of interleukin-23 (anti-IL23), rituximab (anti-CD20 antibody), dupilumab (anti-IL4/IL13) and intravenous immunoglobulin. Their immunomodulatory action may be associated with an increase in the risk of infections in the short and long term, and each case must be assessed individually, according to the risk inherent to the drug, the patient general condition, and the need for precautions. This article will discuss the main risks of infection associated with the use of immunobiologicals, addressing the risk in immunocompetent and immunosuppressed patients, vaccination, fungal infections, tuberculosis, leprosy, and viral hepatitis, and how to manage the patient in the most diverse scenarios.

Impact of sustained virologic response on glucose parameters among patients with chronic hepatitis C treated with direct-acting antivirals

ABSTRACT Objective: The aim of this study was to evaluate the glycated hemoglobin (HbA1c) levels before and after sustained virologic response (SVR) and investigate the baseline characteristics associated with improved glycemic control in patients with chronic hepatitis C (CHC) achieving SVR after direct-acting antivirals (DAA) therapy. Materials and methods: Consecutive adult patients with CHC who achieved SVR after DAA treatment between January 2016 and December 2017 at Hospital de Clínicas de Porto Alegre (RS, Brazil) were prospectively included. Levels of HbA1c were measured up to 24 weeks before DAA therapy and 12 weeks after SVR. Exclusion criteria were decompensated cirrhosis, HIV and/or hepatitis B virus, liver disease of other etiologies, and/or modification of prediabetes/type 2 diabetes mellitus (PDM/T2DM) management. The primary outcome was a comparison of HbA1c levels before and after SVR. Secondary outcomes were the baseline variables associated with improved glycemic control. Results: The study included 207 patients with a mean age of 60.6±10.7 years, of whom 51.7% were women, 56% had cirrhosis, 37.7% had HCV genotype 3, and 54.5% had baseline T2DM or PDM. The median HbA1c level reduced significantly after SVR (5.5%, interquartile range [IQR] 4.9%-6.3%) compared with baseline (5.7%, IQR 5.3­%-6.7%; p = 0.01). The baseline characteristics associated with improved HbA1c after SVR were cirrhosis, genotype 3, and age ≤ 60 years. Conclusion: Among patients with CHC, SVR after DAA was associated with HbA1c reduction, particularly in those with cirrhosis, genotype 3, and age ≤ 60 years.
