Abstract
BACKGROUND The hepatitis E virus (HEV) infection typically causes acute and self-limiting hepatitis. However, chronic infection can occur in immunocompromised hosts. This study determined the prevalence and impact of HEV infection in liver transplanted (LT) children who had transaminitis. METHODS The demographic data, anti-HEV IgM/IgG, serum/stool HEV RNA, and management for LT children with acute or persistent transaminitis from 2003 to 2020 were retrospectively reviewed. HEV serology was tested by ELISA, and HEV RNA was detected by semi-nested PCR. RESULTS Seventy-two children with LT with persistent transaminitis with a median age of 4.41 (1.32, 9.14) years (55.6% female) and one with acute hepatitis were investigated for HEV infection. Anti-HEV IgM, anti-HEV IgG, serum, or stool HEV RNA was investigated in 95.8% (N = 69), 93.1% (N = 67), 43.1% (N = 31), and 37.5% (N = 27) of patients, respectively. The prevalence of HEV infection was 37.5% (N = 27). There was no significant difference in characteristics between the HEV-infected and HEV-non-infected patients. Moreover, 22.2% (N = 16) and 15.3% (N = 11) of patients had past HEV infection and HEV-related acute or chronic infection, respectively. Most of the patients had primary treatment as the presumed graft rejection without improvement. In two patients, detectable HEV RNA in serum turned undetectable in approximately 2 weeks and 2 months, and liver enzyme levels normalized after reducing immunosuppressive therapy. CONCLUSIONS The prevalence of HEV infection among pediatric LT recipients with hepatitis was high. Chronic HEV infection was evidenced in two patients. Investigations of HEV infection in pediatric LT recipients with persistent transaminitis should guide proper management.

Abstract
Viral hepatitis infections are a great burden in children who have received liver transplant. Hepatotropic viruses can cause liver inflammation that can develop into liver graft fibrosis and cirrhosis over the long term. Immunological reactions due to viral hepatitis infections are associated with or can mimic graft rejection, rendering the condition difficult to manage. Prevention strategies using vaccinations are agreeable to patients, safe, cost-effective and practical. Hence, strategies to eliminate viral hepatitis A and B focus mainly on immunization programmes for children who have received a liver transplant. Although a vaccine has been developed to prevent hepatitis C and E viruses, its use is not licensed worldwide. Consequently, eliminating hepatitis C and E viruses mainly involves early detection in children with suspected cases and effective treatment with antiviral therapy. Good hygiene and sanitation are also important to prevent hepatitis A and E infections. Donor blood products and liver grafts should be screened for hepatitis B, C and E in children who are undergoing liver transplantation. Future research on early detection of viral hepatitis infections should include molecular techniques for detecting hepatitis B and E. Moreover, novel antiviral drugs for eradicating viral hepatitis that are highly effective and safe are needed for children who have undergone liver transplantation.

Abstract
BACKGROUND Liver injury is both very common in infants and children and associated with low immune function. This study aimed to investigate the effect of spleen aminopeptide oral lyophilized powder (SAOLP) on liver injury in infants and children with human cytomegalovirus (HCMV) infection. METHODS In this prospective observational study, 217 infants and children with both liver damage and HCMV infection who were admitted to the Department of Pediatric Gastroenterology, Children's Hospital of Nanjing Medical University between July 2018 and May 2020 were investigated. The median age of patients was 0.75 years (0.36-3.77 years), with 105 male and 112 female participants. All 217 patients received ursodeoxycholic acid (UDCA) and/or reduced glutathione (GDC) therapy. Of these 217 patients, 114 also received SAOLP. Liver function, cellular immunity levels, HCMV antibody titer, and HCMV-DNA load values were measured 1 day before treatment, and on the second and fourth week after treatment. RESULTS After 4 weeks, patients treated with SAOLP showed median levels of serum alanine aminotransferase (ALT), total bilirubin (TB), and direct bilirubin (DB) which were significantly lower than those seen in patients who did not receive it. In addition, the percentage of CD4+ cells was significantly higher in those treated with SAOLP in comparison to those treated with UDCA and/or GDC alone. The number of positive HCMV-immunoglobin M (IgM) patients was also sharply decreased in the group receiving SAOLP. CONCLUSIONS The addition of SAOLP to UDCA and/or GDC therapy may significantly relieve liver injury and reduce the jaundice index by enhancing immune function and anti-HCMV infection ability in infants and children.

The histologic presentation of hepatitis E reflects patients' immune status and pre-existing liver condition. Mod Pathol 2021; 34:233-248. [PMID: 32572157 PMCID: PMC7806507 DOI: 10.1038/s41379-020-0593-1] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2020] [Revised: 05/27/2020] [Accepted: 05/27/2020] [Indexed: 02/08/2023]
Abstract
Infection with the hepatitis E virus (HEV) is one of the main causes of acute hepatitis worldwide. Given that, the histopathology of hepatitis E is relatively poorly characterized, and it is unclear what exactly determines its remarkable variability. The aim of our study was a systematic analysis of hepatitis E histology, especially with regard to the clinical setting. Fifty-two liver samples (48 biopsies, 1 liver explant, 3 autopsy livers) from 41 patients with molecularly proven hepatitis E (28 HEV genotype (gt) 3, three gt 1, one gt 4 and 9 undetermined gt) were systematically evaluated for 33 histopathologic features. Following one approach, the biopsies were assigned to one of five generic histologic patterns. In another approach, they were subjected to hierarchical clustering. We found that 23/41 (56%) patients were immunocompromised, whereas 18 (44%) had no known immunosuppression. Five patients (12%) had pre-existing liver disease (LD). The histopathologic spectrum ranged from almost normal to acute, chronic, and steato-hepatitis to subtotal necrosis, and was thus distributed across all five generic patterns. Hierarchical clustering, however, identified three histopathologic clusters (C1-C3), which segregated along the immune status and pre-existing LD: C1 comprised mostly patients with pre-existing LD; histology mainly reflected the respective LD without pointing to the additional hepatitis E. C2 comprised mostly immunocompetent patients; histology mainly displayed florid hepatitis. C3 comprised mostly immunocompromised patients; histology mainly displayed smoldering hepatitis. Accordingly, C1-C3 differed markedly with respect to their clinical and histopathologic differential diagnoses. Hierarchical clustering suggests three groups with distinct histopathologies, indicating biologically different manifestations of hepatitis E. The association of histopathologic changes with the patient's immune status and pre-existing LD plausibly explains the diversity of hepatitis E histopathology, and suggests that these factors are the crucial underlying determinants. We expect our results to improve patient management by guiding the clinico-pathologic diagnosis of hepatitis E.

Abstract
Hepatitis E virus infection has been recognized as a rising hepatotropic viral infection in the developing countries but overlooked in the developed countries, due to its lower prevalence. However, hepatitis E virus prevalence is on rise in the liver transplant recipients due to immunosuppression, which needs prompt recognition by healthcare practitioners. Hepatitis E virus infection is commonly believed to be transmitted via an animal host; but in the post-liver transplant patients, it can also be acquired via blood and blood products transfusion and autochthonous route. Previous studies have shown the significance of hepatitis E virus infection in post-liver transplant, as the patients at a high risk of progressing to chronic hepatitis and cirrhosis. Pediatric patients are at higher risk of hepatitis E virus infection post-liver transplant. Specific hepatitis E virus genotypes have the potential for greater severity. The clinical manifestation of hepatitis E virus can also present as extrahepatic features which need high level of suspicion for early recognition and treatment. Treatment options of hepatitis E virus range from immunosuppressive drug minimization, ribavirin therapy to novel direct-acting antiviral regimens. Herein, we aim to explore epidemiology, prevalence, risk factor, diagnosis, and management of hepatitis E virus infection giving special attention to liver transplant recipients.

Abstract
BACKGROUND AND AIMS Sporadic hepatitis E is an emerging indigenous disease in Europe induced by genotype 3 of the virus. While the disease takes an acute self-limited course in immunocompetent individuals, under immunocompromised conditions chronic hepatitis E might develop. The histology of chronic hepatitis E has not been described in detail systematically. METHODS Liver biopsies from 19 immunosuppressed patients with chronic hepatitis E were collected: 17 were organ transplant recipients, one had a CD4-deficiency and one had received steroid therapy because of ulcerative colitis. Biopsies were processed with standard stains. Evaluation of histologic activity and fibrosis was performed according to Ishak. Additionally, immunohistochemistry with antibodies directed against open reading frame 2 and 3 of the virus was performed and liver biopsies were tested for hepatitis E virus RNA. RESULTS Biochemical data showed an increase in alanine transaminase, aspartate transaminase, gamma-glutamyl transferase and total bilirubin. Histopathology displayed typical features of chronic hepatitis with mild to moderate activity. The number of polymorphonuclear leucocytes was considerably increased and all patients had a florid cholangitis that presented as a destructive form in five of them. Hepatocytes and bile duct epithelia stained positive for hepatitis E virus by immunohistochemistry. CONCLUSIONS Chronic hepatitis E in immunocompromised individuals runs a similar course as hepatitis B and C and shows similar histopathology. However, the presence of destructive cholangitis in some cases accompanied by an increased number of polymorphonuclear leucocytes is markedly different. Immunohistochemically the virus is present in bile duct epithelia, seemingly the cause for cholangitis.

Abstract
Infection with the hepatitis E virus (HEV) is globally seen a leading cause of hepatitis. Now increasingly recognized also in industrialized countries, hepatitis E constitutes a significant health problem worldwide. The patient's immune status determines the clinical course and histopathology of hepatitis E. In immunocompetent patients, hepatitis E usually follows an asymptomatic or subclinical course, but may also present with acute hepatitis. In contrast, immunocompromised patients may develop chronic hepatitis, and patients with preexisting liver diseases are at risk for liver decompensation with potentially fatal outcome. Whereas pathologists only occasionally encounter liver biopsies from immunocompetent individuals with hepatitis E, they are more likely exposed to biopsies from patients with preexisting liver disease or immunocompromised individuals. Histopathologic hallmarks of hepatitis E in immunocompetent patients comprise lobular disarray, lobular, and portal inflammation, as well as hepatocyte necrosis of varying extend and regeneration. Thus, it is similar to acute non-E viral hepatitis, yet further differential diagnoses include autoimmune hepatitis and drug-induced liver injury. Histopathologic findings of hepatitis E in preexisting liver disease are determined by the underlying pathology, but may be more severe. Histopathologic presentation of hepatitis E in immunocompromised patients is highly variable, ranging from minimal active hepatitis to chronic hepatitis with severe activity and progressive fibrosis. Taken together, the variability of the histologic features depending on the clinical context and the overlap with other liver diseases make the histopathologic diagnosis of hepatitis E challenging. Immunohistochemistry for HEV open reading frame 2 protein and molecular testing for HEV RNA are useful tissue-based ancillary tools.
