RESUMEN

Since the coronavirus disease pandemic response began in March 2020, tests, vaccinations, diagnoses, and treatment initiations for sexual health, HIV, and viral hepatitis in England have declined. The shift towards online and outreach services happened rapidly during 2020 and highlights the need to evaluate the effects of these strategies on health inequalities.

RESUMEN

Hepatitis virus infections affect a large proportion of the global population. The host responds rapidly to viral infection by orchestrating a variety of cellular machineries, in particular, the mitochondrial compartment. Mitochondria actively regulate viral infections through modulation of the cellular innate immunity and reprogramming of metabolism. In turn, hepatitis viruses are able to modulate the morphodynamics and functions of mitochondria, but the mode of actions are distinct with respect to different types of hepatitis viruses. The resulting mutual interactions between viruses and mitochondria partially explain the clinical presentation of viral hepatitis, influence the response to antiviral treatment, and offer rational avenues for novel therapy. In this review, we aim to consider in depth the multifaceted interactions of mitochondria with hepatitis virus infections and emphasize the implications for understanding pathogenesis and advancing therapeutic development.

RESUMEN

We report a case of blood exchange transfusion to treat acute liver failure following hepatitis B infection at the Infectious Disease Department of Children's Hospital No.2 in Ho Chi Minh City, Vietnam. A 3.5-month old baby boy was admitted to the hospital with a presentation of progressively worsening jaundice for the past one month. The patient was diagnosed with hepatitis B infection with a positive HBV DNA quantitative assay. Plasma exchange was indicated in view of progressive liver failure and gradually increasing hepatic coma. However, it was impossible to perform plasmapheresis in this case because the patient was small (in terms of age and weight) and there was no suitable plasma exchange filter. Accordingly, the patient was treated with 3 times of blood exchange transfusion in combination with an antiviral drug, lamivudine. After each blood exchange transfusion, the biochemical values (bilirubin, liver enzymes, and coagulation profile) gradually improved and he was discharged after 1 month of treatment. Blood exchange transfusion is an effective procedure for managing acute liver failure, where plasma exchange is not possible while waiting for the recovery of liver functions or liver transplantation.

RESUMEN

Various atypical manifestations have been described in acute viral hepatitis (AVH). We evaluated the prevalence, clinical features, response to treatment and outcome of various atypical manifestations of AVH in children. Consecutive children (≤ 18 years) with AVH due to hepatitis A, B, or E were studied while patients with acute or acute on chronic liver failure were excluded. Diagnosis of atypical manifestations was based on standard criteria. A total of 477 children with AVH (median age 7.0 (5-11) years, 74% boys) were seen; 22% (n = 106) had atypical manifestations. Prolonged cholestasis was the most common (11%), followed by ascites (7%), intravascular hemolysis (3%), relapsing hepatitis (2%), acute pancreatitis (1.3%), and thrombocytopenia (0.7%). Atypical manifestations were more common in HAV as compared to HBV (30% vs. 3%, p = 0.00) and HEV (30% vs. 15%, p = 0.07). Prolonged cholestasis was significantly more common in older children (20% in > 10 years vs. 9% in 6-10 years ; p = 0.009 and 5% in 0-5 years of age [p < 0.000]). Ascites was more common in younger children, although not significant. All patients recovered with supportive treatment.Conclusions: Twenty-two percent of children with AVH have atypical manifestations, more often with HAV infection, and prolonged cholestasis is most common. Recognition of these manifestations ensures correct diagnosis and treatment. What is Known: • Acute viral hepatitis is a major public health problem in developing countries. • There is limited information about atypical manifestations which may lead to unnecessary investigations, delayed diagnosis and morbidity. What is New: • Atypical manifestations are common in children, seen most often with HAV infection, and prolonged cholestasis is most common. • Prompt recognition of these manifestations helps in early diagnosis, appropriate management, and preventing unnecessary investigations. • Ensure follow-up until complete recovery and not to miss underlying chronic liver disease.

RESUMEN

Liver disease during pregnancy is more common than expected and may require specialized intervention. It is important to determine if changes in liver physiology may develop into liver disease, to assure early diagnosis. For adequate surveillance of mother-fetus health outcome, liver disease during pregnancy might require intervention from a hepatologist. Liver diseases have a prevalence of at least 3% of all pregnancies in developed countries, and they are classified into two main categories: related to pregnancy; and those non- related that are present de novo or are preexisting chronic liver diseases. In this review we describe and discuss the main characteristics of those liver diseases associated with pregnancy and only some frequent pre-existing and co-incidental in pregnancy are considered. In addition to the literature review, we compiled the data of liver disease occurring during pregnancies attended at the National Institute of Perinatology in Mexico City in a three-year period. In our tertiary referral women hospital, liver disease was present in 11.24 % of all pregnancies. Associated liver disease was found in 10.8% of all pregnancies, mainly those related to pre-eclampsia (9.9% of pregnancies). Only 0.56% was due to liver disease that was co-incidental or preexisting; the acute or chronic hepatitis C virus was the most frequent in this group (0.12%). When managing pregnancy in referral hospitals in Latin America, it is important to discard liver alterations early for adequate follow up of the disease and to prevent adverse consequences for the mother and child.

RESUMEN

BACKGROUND: General practitioners encounter the vast majority of patients with Epstein-Barr virus-related disease, i.e. infectious mononucleosis in children and adolescents. With the expanding knowledge regarding the multifaceted role of Epstein-Barr virus in both benign and malignant disease we chose to focus this review on Epstein-Barr virus-related conditions with relevance to the general practitioners. A PubMed and Google Scholar literature search was performed using PubMed's MeSH terms of relevance to Epstein-Barr virus/infectious mononucleosis in regard to complications and associated conditions. MAIN TEXT: In the present review, these included three early complications; hepatitis, splenic rupture and airway compromise, as well as possible late conditions; lymphoproliferative cancers, multiple sclerosis, rheumatoid arthritis, and chronic active Epstein-Barr virus infection. This review thus highlights recent advances in the understanding of Epstein-Barr virus pathogenesis, focusing on management, acute complications, referral indications and potentially associated conditions. CONCLUSIONS: Hepatitis is a common and self-limiting early complication to infectious mononucleosis and should be monitored with liver tests in more symptomatic cases. Splenic rupture is rare. Most cases are seen within 3 weeks after diagnosis of infectious mononucleosis and may occur spontaneously. There is no consensus on the safe return to physical activities, and ultrasonic assessment of spleen size may provide the best estimate of risk. Airway compromise due to tonsil enlargement is encountered in a minority of patients and should be treated with systemic corticosteroids during hospitalization. Association between lymphoproliferative cancers, especially Hodgkin lymphoma and Burkitt lymphoma, and infectious mononucleosis are well-established. Epstein-Barr virus infection/infectious mononucleosis as a risk factor for multiple sclerosis has been documented and may be linked to genetic susceptibility. Chronic active Epstein-Barr virus infection is rare. However, a general practitioner should be aware of this as a differential diagnosis in patients with persisting symptoms of infectious mononucleosis for more than 3 months.

RESUMEN

BACKGROUND: Viral myocarditis presents with various symptoms, including fatal arrhythmia and cardiogenic shock, and may develop into chronic myocarditis and dilated cardiomyopathy in some patients. We report a case of viral myocarditis and hepatitis caused by herpes simplex virus. CASE PRESENTATION: A 20-year-old woman was admitted to our hospital with fever, fatigue, and anorexia. The initial investigation showed elevated liver enzyme levels and elevated creatine phosphokinase, and computed tomography showed diffuse swelling and internal heterogeneous image in the liver. These findings were consistent with acute hepatitis; therefore, we performed a liver biopsy, which showed parenchymal necrosis and lymphocytic infiltration. The night that the liver biopsy was performed, blood pressure gradually decreased and revealed cardiogenic shock. Electrocardiography showed diffuse ST-segment elevation, and echocardiography showed a dilated, spherical ventricle with reduced systolic function and pericardial effusion. An endomyocardial biopsy revealed lymphocyte infiltration of the myocardium, confirming acute myocarditis. After a few days, tests for immunoglobin M and immunoglobin G antibodies against herpes simplex virus were positive. CONCLUSIONS: We presented a rare case of myocarditis combined with hepatitis that was caused by herpes simplex virus. Acute myocarditis can occur concurrently with hepatitis, pancreatitis, nephritis, and encephalitis; thus, determining the presence of other infectious lesions is necessary to provide appropriate treatment for the patient.

RESUMEN

INTRODUCTION: Viral hepatitis represents a serious public health problem in the world especially in the Maghreb where the prevalence of the 5 viruses A, B, C, D, and E remains high and varies from one Maghreb country to another, there is few published studies on these infections in our Maghreb countries. METHOD OF STUDY: Our work is a review of the literature about prevalence, the most common mode of transmission, and the most exposed population for these viruses in the Maghreb countries through published studies between 2011 and 2017. RESULT: It has been found that the Maghreb countries are endemic for the five viruses with variable prevalence from one country to another, with sometimes heterogeneous data in the same country. For hepatitis B, Mauritania is the Maghreb country most affected by this infection unlike the rest of the Maghreb countries which are moderately endemic for this virus, the lowest prevalence of VHB was noted in Morocco, the genotype the most common is the D for the majority of Maghreb countries, and the precore mutant profile is also the most common. For hepatitis C the prevalence of infection does not vary much from one Maghreb country to another, but it remains slightly higher in Mauritania. The population most exposed to the virus C in the five countries is hemodialysis patients. The most common genotype in all Maghreb countries is genotype 1 except for Libya, where genotype 4 remains the most common probably related to its borders with Egypt. For hepatitis D, Mauritania is the only Maghreb country with a high endemicity for the virus. Tunisia has the lowest prevalence for hepatitis A and E compared to the rest of the Maghreb countries, all of which are endemic for these two viruses with fecal-oral transmission. CONCLUSION: The management of these viral hepatitis is costly for the health economy and to reduce their prevalence, prevention measures must be followed like vaccination and improving hygiene conditions.

RESUMEN

The burden of HIV/AIDS and other transmissible diseases is higher in prison and jail settings than in the non-incarcerated communities that surround them. In this comprehensive review, we discuss available literature on the topic of clinical management of people infected with HIV, hepatitis B and C viruses, and tuberculosis in incarcerated settings in addition to co-occurrence of one or more of these infections. Methods such as screening practices and provision of treatment during detainment periods are reviewed to identify the effect of community-based treatment when returning inmates into the general population. Where data are available, we describe differences in the provision of medical care in the prison and jail settings of low-income and middle-income countries compared with high-income countries. Structural barriers impede the optimal delivery of clinical care for prisoners, and substance use, mental illness, and infectious disease further complicate the delivery of care. For prison health care to reach the standards of community-based health care, political will and financial investment are required from governmental, medical, and humanitarian organisations worldwide. In this review, we highlight challenges, gaps in knowledge, and priorities for future research to improve health-care in institutions for prisoners.

RESUMEN

Blood-borne viruses, such as hepatitis B virus, hepatitis C virus, human immunodeficiency virus, and the facultative blood-borne hepatitis E virus, are considered a major public health problem given that they are accountable for millions of deaths each year. Treatment options, including effective vaccine design, development of antiviral strategies and the implementation of antiretroviral therapy have improved substantially over the last couple of years and contribute to successful treatment and prevention of these infectious diseases. In this review, we summarise the current knowledge and concepts in prevention of transmission of these blood-borne viruses.

RESUMEN

BACKGROUND: As more countries worldwide develop national viral hepatitis strategies, it is important to ask whether context-specific factors affect their decision-making. This study aimed to determine whether country-level socioeconomic factors are associated with viral hepatitis programmes and policy responses across WHO Member States (MS). METHODS: WHO MS focal points completed a questionnaire on national viral hepatitis policies. This secondary analysis of data reported in the 2013 Global Policy Report on the Prevention and Control of Viral Hepatitis in WHO Member States used logistic regression to examine associations between four survey questions and four socioeconomic factors: country income level, Human Development Index (HDI), health expenditure and physician density. RESULTS: This analysis included 119 MS. MS were more likely to have routine viral hepatitis surveillance and to have a national strategy and/or policy/guidelines for preventing infection in healthcare settings if they were in the higher binary categories for income level, HDI, health expenditure and physician density. In multivariable analyses, the only significant finding was a positive association between having routine surveillance and being in the higher binary HDI category (adjusted odds ratio 26; 95% confidence interval 2.0-340). CONCLUSION: Countries with differing socioeconomic status indicators did not appear to differ greatly regarding the existence of key national policies and programmes. A more nuanced understanding of the multifaceted interactions of socioeconomic factors, health policy, service delivery and health outcomes is needed to support country-level efforts to eliminate viral hepatitis.

RESUMEN

The authors give their own data in the first Russian publication on 170 patients with lymphomas and hepatitis concurrent with HIV infection, on the distribution of therapy regimens by nosological entities and the number of deaths. Conventional protocols and programs were used for diagnosis and treatment. All the patients received highly active antiretroviral therapy. Lymphoma was treated according to the conventional programs using rituximab in people without hepatitis B. Aggressive lymphomas, such as diffuse large B-cell lymphoma, Burkitt lymphoma, and plasmablastic lymphoma, were identified in most patients. Hodgkin's lymphoma is the matter of a separate study; it differs in its pathogenesis from other lymphomas. The rate of coinfection with hepatitis was high in the entire group of patients with lymphomas. The major prognostic indicators included low CD4 T-cell counts (less than 50), stage IVB lymphoma, and hepatitis. Complete remissions were achieved in 40% of patients. Forty-one (24%) patients died.

RESUMEN

Viral hepatitis is a systemic disease that predominantly affects the liver. The most common causes of viral hepatitis are fi ve hepatotropic viruses A, B, C, D and E; according to duration, it can be acute or chronic. Although clinical course of all viral hepatitides is similar, particular problem is predisposition of hepatitis B and hepatitis C to cause chronic forms of illness with severe outcome such as cirrhosis, hepatocellular carcinoma and liver failure. Clinical features include malaise, nausea, anorexia, low grade fever, aversion to smoking, and in clinical status usually we can fi nd hepatomegaly, and seldom splenomegaly with adenopathy and jaundice. Generally, symptoms are very variable, from usually asymptomatic to fulminant, which in most cases have lethal outcome. There are three stages in acute phase of viral hepatitis: prodromal, icteric and convalescence. Standard laboratory tests show elevated values of aspartate aminotransferase, alanine aminotransferase and alkaline phosphatase in acute phase of hepatitis and elevated lactate dehydrogenase in chronic phase. Serum protein electrophoresis usually shows decreased albumin fraction and albumin/globulin ratio, as well as increased bilirubin level, positive urobilinogen and disturbance in coagulability factors, i.e. marked prolongation of prothrombin time. For etiology of each virus, series of serologic tests are used. In hepatitis A, acute phase of disease is characterized by IgM anti-HAV and presence of IgG anti-HAV indicates previous exposure. In hepatitis B, appearance of HBsAg in serum is the fi rst evidence of infection and recovery is connected with appearance of anti-HBsAg along with IgG anti HBcAg. Active forms of chronic hepatitis B are characterized by active virus replication, which can be measured with polymerase chain reaction (PCR) HBV DNA. Diagnosis of hepatitis C is based on detection of antibodies to HCV (anti-HCV). Generally, it signifi es that HCV infection is present but that diagnostic tool is poor for the phase of disease. In these circumstances, diagnosis of hepatitis C may be confi rmed by using an assay for HCV RNA. First line therapy in acute phase is mostly supportive, i.e. bed rest, appropriate diet including palatable meals as tolerated, without overfeeding. Alcohol and hepatotoxic agents (for example, paracetamol, amoxicillin, ketoconazole) should be avoided. In cases with increased tendency of developing chronic forms of hepatitis and complications (cirrhosis, hepatocellular carcinoma), immunomodulators should be administered, e.g., interferon and/or antiviral agents. The role of family physician/general practitioner is in maintaining preventive measures (vaccination) and education of general population. Special attention needs to be paid to screening and educating high risk patients with respect to proper diagnostics, laboratory and serologic tests. After establishing the diagnosis, all relevant measures should be taken to avoid chronifi cation of disease. In case of chronic hepatitis, consultation with infectious disease specialist and/or gastroenterologist is needed in the treatment and follow up of the patient.

RESUMEN

Pregnancy is a para-physiologic condition, which usually evolves without any complications in the majority of women, even if in some circumstances moderate or severe clinical problems can also occur. Among complications occurring during the second and the third trimester very important are those considered as concurrent to pregnancy such as hyperemesis gravidarum, intrahepatic cholestasis of pregnancy, HELLP syndrome and acute fatty liver of pregnancy. The liver diseases concurrent to pregnancy typically occur at specific times during the gestation and they may lead to significant maternal and foetal morbidity and mortality. Commonly, delivery of the foetus, even preterm, usually terminates the progression of these disorders. All chronic liver diseases, such as chronic viral hepatitis, autoimmune hepatitis, Wilson's disease, and cirrhosis of different aetiologies may cause liver damage, independently from pregnancy. In this review we will also comment the clinical implications of pregnancies occurring in women who received a orthotopic liver transplantation (OLT) Therefore, the management of immunosuppressive therapy before and after the delivery in women who received liver transplant is becoming a relevant clinical issue. Finally, we will focus on acute and chronic viral hepatitis occurring during pregnancy, on management of advanced liver disease and we will review the literature on the challenging issue regarding pregnancy and OLT.

RESUMEN

PURPOSE: To determine any differences in patient characteristics and outcomes after transarterial chemoembolization between different viral etiologies of hepatocellular carcinoma (HCC). METHODS: This retrospective study consisted of 201 patients undergoing first-time transarterial chemoembolization for unresectable HCC from January to December 2009. The patients were divided into four groups: hepatitis B virus (HBV) only (n = 104), hepatitis C virus (HCV) only (n = 63), HBV and HCV (n = 10), and no viral hepatitis (n = 24). The clinical and laboratory data were obtained from electronic medical records, and imaging findings obtained before transarterial chemoembolization were analyzed. Kaplan-Meier analyses were used to assess the impact of HBV or HCV status, clinical characteristics, and imaging results on overall survival. RESULTS: After a median follow-up of 28.3 months ± 16.2, the 1-, 2-, and 3-year overall survival rates were 74.1%, 59.7%, and 53.2%. Patients with HBV had a significant association with younger age (P = .001), higher male-to-female ratio (P = .003), lower alanine aminotransferase levels (P = .018), higher albumin levels (P = .009), and multifocal tumors at diagnosis (P = .04) compared with patients with HCV. Patients with both HBV and HCV had significantly higher serum bilirubin levels compared with the other groups (P = .002). No significant difference was found in overall survival among the different hepatitis groups (P = .943). Multivariate analysis showed that statistically significant determinants for overall survival were Child-Pugh class (P = .002), Barcelona Clinic Liver Cancer stage (P < .001), tumor size (P < .001), and distribution (P < .001). CONCLUSIONS: Viral etiology has no correlation with the outcome of patients with HCC undergoing transarterial chemoembolization.

RESUMEN

Cirrhosis secondary to hepatitis C virus infection is the leading cause of liver transplantation in most countries. Hepatitis C has an accelerated course after transplantation, and for this reason graft and patient survival are decreased in comparison with other indications of liver transplantation. The development of direct-acting antivirals has been a major step in the management of hepatitis C and in a few years from now the infection will be eradicated with the combination of oral drugs with a good safety profile. This will likely allow prevention of hepatitis C recurrence in most cases. Meanwhile, management of hepatitis C virus infection still relies on the combination of interferon, ribavirin and the first-generation protease inhibitors telaprevir and boceprevir.

RESUMEN

Acute inflammation of the liver (hepatitis) can be triggered by at least five different hepatotropic viruses - hepatitis viruses A, B, C, D and E. Hepatitis viruses A and E are transmitted via contaminated food and smear infections, whereas hepatitis viruses B, C and D are transmitted through direct contact with blood and other body fluids when these penetrate the skin or mucous membranes. This article is intended to provide a brief overview of the different forms of acute viral hepatitis, diagnosis, course and treatment.

RESUMEN

Viral hepatitis represents a major danger to public health, and is a globally leading cause of death. The five liver-specific viruses: Hepatitis A virus, hepatitis B virus, hepatitis C virus, hepatitis D virus, and hepatitis E virus, each have their own unique epidemiology, structural biology, transmission, endemic patterns, risk of liver complications, and response to antiviral therapies. There remain few options for treatment, in spite of the increasing prevalence of viral-hepatitis-caused liver disease. Furthermore, chronic viral hepatitis is a leading worldwide cause of both liver-related morbidity and mortality, even though effective treatments are available that could reduce or prevent most patients' complications. In 2016, the World Health Organization released its plan to eliminate viral hepatitis as a public health threat by the year 2030, along with a discussion of current gaps and prospects for both regional and global eradication of viral hepatitis. Today, treatment is sufficiently able to prevent the disease from reaching advanced phases. However, future therapies must be extremely safe, and should ideally limit the period of treatment necessary. A better understanding of pathogenesis will prove beneficial in the development of potential treatment strategies targeting infections by viral hepatitis. This review aims to summarize the current state of knowledge on each type of viral hepatitis, together with major innovations.
