Inflammation is a part of the first line of defense of the body against invasive pathogens, and plays a crucial role in tissue regeneration and repair. A proper inflammatory response ensures the suitable resolution of inflammation and elimination of harmful stimuli, but when the inflammatory reactions are inappropriate it can lead to damage of the surrounding normal cells. The relationship between infections and Alzheimer's Disease (AD) etiology, especially late-onset AD (LOAD) has been continuously debated over the past three decades...

OBJECTIVES: Hepatitis E virus (HEV) genotype 3 is endemic in Europe and an underdiagnosed and emerging (public) health issue. In recent years commercial enzyme immunoassays (EIAs) that detect antibodies to HEV more adequately, became available. We investigated the added value of this HEV serology in the diagnostic work flow to detect viral causes of recent hepatitis. METHODS: During a two year period (May 2013 - May 2015), HEV serology was added to the hepatitis work flow, consisting of serological detection of hepatitis A-B-C virus (HAV, HBV, HCV), Epstein-Barr Virus (EBV) and Cytomegalovirus (CMV)...

Human cytomegalovirus is a significant agent of hepatic involvement in neonates. In this study, we investigated the polymorphisms and features of the viral genes UL144 and UL146 as well as their significance to congenital hepatic involvement. In 79 neonates with congenital cytomegalovirus infection and hepatic involvement, full length UL144 and UL146 were successfully amplified in 73.42% and 60.76% of cases, respectively. Sequencing indicated that both genes were hypervariable. Notably, UL144 genotype B was highly associated with aspartate aminotransferase (P = 0...

BACKGROUND: Living donor liver transplantation is now an established technique for treating children with end-stage liver disease. Few data exist about liver transplantation for exclusively young infants, especially infants of <3 months of age. We report our single-center experience with 12 cases in which living donor liver transplantation (LT) was performed during the first 3 months of life and compare the results with those of older infants who underwent LT. All of the patients were treated at the National Center of Child Health and Development, Tokyo, Japan...

BACKGROUND: Tyrosinemia is an inherited metabolic disorder characterized by elevated levels of tyrosine and its metabolites in plasma. Without treatment, the disease will progress to hepatic and renal failure, so that without liver transplantation will cause death in less than 10 years of age. So, early diagnosis and treatment can be life saving and crucial. It means that with early treatment starting in the neonatal period, the patient can have normal life with very few restrictions in diets containing tyrosine and phenylalanine...

BACKGROUND Hepatitis B virus (HBV) has been reported as a coinfection with hepatitis C virus (HCV), hepatitis D virus (HDV), cytomegalovirus (CMV), and human immunodeficiency virus (HIV). CASE REPORT A 34-year-old female presented to our clinic with epigastric pain and severe acute hepatitis manifested as jaundice associated with hyperbilirubinemia, elevated transaminases, and coagulopathy. The patient was diagnosed with acute HBV with Epstein-Barr virus (EBV) coinfection leading to subsequent chronic hepatitis B...

The complicated replication mechanisms of hepatitis B virus (HBV) have impeded HBV studies and anti-HBV therapy development as well. Herein we report efficient genome replication of HBV applying adenovirus vectors (AdVs) showing high transduction efficiency. Even in primary hepatocytes derived from humanized mice the transduction efficiencies using AdVs were 450-fold higher compared than those using plasmids. By using an expression unit consisting of the CMV promoter, 1.03-copy HBV genome and foreign poly(A) signal, we successfully generated an improved AdV (HBV103-AdV) that efficiently provided 58 times more pregenomic RNA than previously reported AdVs...

The complications and outcome associated with late CMV infection and disease on the graft are poorly characterized in PLT recipients. We studied the overall incidence, risk factors, and outcome of late CMV infection and disease (infection 6 months after transplant) in 180 PLT recipients admitted between 2008 and 2011 at the King's College Hospital. Antiviral prophylaxis of intravenous ganciclovir was given only to the D+R- group starting at day 7 post-transplant. The remaining groups (D-R+, D+R+, and D-R-) received pre-emptive therapy when they have CMV viremia above cut-off value and treatment for symptomatic CMV infection...

REVIEW
Rogier van Gent, Herold J Metselaar, Jaap Kwekkeboom
Hyperimmunoglobulins are pharmaceutical formulations of human IgG which contain high titers of antibodies against specific viruses. They have been successfully used in solid organ transplantation (SOT) to prevent Cytomegalovirus (CMV) and Hepatitis B Virus (HBV) infection. The introduction of effective and cheaper antiviral drugs has resulted in decreasing usage of hyperimmunoglobulins in SOT. However, it may still be attractive to combine antiviral drug therapy with hyperimmunoglobulins after SOT, as there is some evidence that hyperimmunoglobulins, similar to high doses of intravenous immunoglobulins (IVIgs), might exert anti-inflammatory activity and thereby prevent immunological graft damage and improve graft and patient survival...

BACKGROUND: The risks for transplant outcomes associated with baseline viral serostatus in kidney transplant recipients (KTR) on sirolimus have not been widely studied. METHODS: We performed a cohort-study of 61 590 adult KTR in 2000 to 2013. We used Cox regression models to determine the adjusted hazard ratio (aHR) of patient death, death-censored graft loss and posttransplant malignancy associated with the baseline serostatus (+ or -: hepatitis B core [HBc], hepatitis C virus [HCV], Epstein-Barr virus [EBV], or cytomegalovirus [CMV]) in KTR on sirolimus (SRL) + mycophenolate (MPA) or SRL + tacrolimus (Tac), relative to the control-regimen: Tac + MPA...

The Scientific Registry of Transplant Recipients (SRTR) serves to collect data on organ transplants performed in the United States. Although the infectious diseases data are limited and include mostly pretransplant serologies and other nonspecific infection-related outcomes, this multicenter data collection allows for insightful national data and the ability to monitor trends over time. We reviewed the published concise reports for each organ type in SRTR reports containing data from 2005 to 2014, and summarized our findings with respect to cytomegalovirus (CMV), Epstein-Barr virus, posttransplant lymphoproliferative disorder (PTLD), hepatitis B virus (HBV), hepatitis C virus (HCV), HIV, general infection, and prophylaxis...

STAT4 polymorphism, rs7574865 is linked to various autoimmune diseases such as systemic lupus erythematosus and rheumatoid arthritis. Its T minor allele is associated with higher STAT4 mRNA and protein expression, indicating a stronger skewed immune response than the norm. Although widely studied in autoimmune disease patients and the general population, its effect on immunocompromised subjects is still unknown. Especially in situations, i.e. post-hematopoietic stem cell transplantation (post-HSCT), where control of the immune response is crucial...

BACKGROUND: The prevalence of HCV infection in people with hemophilia is substantially higher than that in the general population (63% - 98%). Multiple transfusions and substitutive therapy have also been linked to a high risk of HBV and HIV transmission. However, the prevalence of other blood-borne viral infections in this population is less well known. OBJECTIVES: This study aimed to assess the prevalence of co-infection with HBV and other blood-borne viruses in Polish HCV-infected hemophiliacs...
