PURPOSE OF REVIEW: Obesity is a multifactorial disease that is now endemic throughout most of the world. Although addressing proximate causes of obesity (excess energy intake and reduced energy expenditure) have been longstanding global health priorities, the problem has continued to worsen at the global level. RECENT FINDINGS: Numerous microbial agents cause obesity in various experimental models-a phenomena known as infectobesity. Several of the same agents alter metabolic function in human cells and are associated with human obesity or metabolic dysfunction in humans...

Biological drugs (tumor necrosis factor inhibitors, rituximab, tocilizumab, abatacept, and tofacitinib) are important treatment alternatives in rheumatology, particularly for resistant patients. However, they may cause hepatitis B virus (HBV) and hepatitis C virus (HCV) reactivation; for instance, HBV reactivation may occur in a patient who is an inactive hepatitis B surface antigen (HBsAg) carrier or who has resolved HBV infection. Therefore, the screening of patients before biological treatment and the application of a prophylactic treatment, particularly with respect to latent HBV infections, are recommended when necessary...

The present review considers malaria infection concurrent with different species of helminths, bacterial and viral infections, as well as mixed malaria pathogens in the subtropical and tropical countries of the world, causing the clinical picture and epidemiological situation to be different. Malaria co-infections with different pathogenic micro-organisms, such as HIV, tuberculosis, viral hepatitides, and others, affect almost one third of the planet's population. It is known that people who are at risk for malaria may be also at risk for other parasitic and infectious diseases, most commonly helminthisms...

Idiopathic adulthood ductopenia (IAD) is a chronic cholestatic entity of unknown origin characterized by loss of inter-lobular bile ducts that was first described two decades ago. Although the diagnostic criteria have been described in detail, IAD continues to be a rare diagnosis. Our thorough literature search revealed less than a hundred cases of IAD reported. Here we present a 34-year-old female with no significant past history who was evaluated for persistent elevation of serum alkaline phosphate levels...

BACKGROUND: Acute liver failure (ALF) is characterized by a sudden loss of hepatic function due to hepatocyte cell death and dysfunction in previously healthy individuals. The clinical presentation of ALF is associated with coagulopathy (international normalized ratio ≥1.5) and hepatic encephalopathy, although the latter may be less pronounced. Without appropriate and timely intensive care or liver transplantation (LTx), ALF will result in multi-organ failure and death. Various causes may induce ALF, with acetaminophen (APAP) intoxication and acute hepatitis B infection as most common causes in industrialized countries...

Between 1963 and 1989, 5 hepatotropic viruses have been discovered that are the major causes of viral hepatitides worldwide: hepatitis A virus, hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis delta virus and hepatitis E virus. Their epidemiology and pathogenesis have been studied in great detail. Furthermore, the structure and genetic organization of their DNA or RNA genome including the viral life cycle have been elucidated and have been successfully translated into important clinical applications, such as the specific diagnosis, therapy and prevention of the associated liver diseases, including liver cirrhosis and hepatocellular carcinoma (HCC)...

AIM: To investigate the impact of therapy with the infusion hepatoprotector remaxol on liver function in cirrhosis in the outcome of chronic viral hepatitides (CVH): HCV, HBV, HCV+HBV, and HBV+HDV. SUBJECTS AND METHODS: Sixty-five patients aged 26 to 76 years, who had been diagnosed as having liver cirrhosis (LC) in the outcome of CVH: HCV, HBV, HCV+HBV, and HBV+HDV were examined. During infusion therapy, every day 32 cirrhotic patients in the outcome of CVH B or C received intravenous remaxol 400 ml in a jetwise manner once daily for 11 days...

Hepatocellular carcinoma (HCC) generally occurs on the background of chronic liver disease. Chronic hepatitides B and C and alcoholic liver disease are well-known risk factors for HCC, and it is uncommon in noncirrhotic liver. Extrahepatic metastasis seldom occurs in patients with early stage intrahepatic HCC and isolated bone metastases as a first documented extrahepatic metastasis is unusual presentation. In this report, we present a rare case of small solitary HCC (<3 cm) in noncirrhotic liver, presenting isolated bone metastases as a sole manifestation in patient with no well-known risk factors...

Data evaluating the screening practices for viral hepatitides and sexually transmitted infections (STIs) in patients presenting for non-occupational HIV post-exposure prophylaxis (nPEP) care are limited. Screening practices and prevalences of viral hepatitides and STIs were evaluated in 126 patients presenting to a dedicated HIV prevention clinic for HIV nPEP. Three patients (2.4%) were diagnosed with chronic hepatitis C infection, 28 (22.2%) did not have surface antibodies in sufficient quantity to confer immunity to hepatitis B, and six (4...

BACKGROUND AND AIMS: Hepatitis E virus (HEV) infection is a significant public health problem that afflicts almost 20 million individuals annually and causes acute liver injury in 3.5 million, with approximately 56 000 deaths. As with other viral hepatitides, extra-hepatic manifestations could represent an important aspect of this infection. The spectrum of these manifestations is still emerging. Acute pancreatitis and neurological, musculoskeletal, hematological, renal, and other immune-mediated manifestations have been described...

OBJECTIVE: Involvement of the pancreato-biliary system has been occasionally noted in Henoch-Schönlein purpura. Furthermore, cases of this vasculitis syndrome sometimes develop in the context of a viral hepatitis or after hepatitis vaccination. METHODS: We completed a review of the literature. RESULTS: Fifty reports published between 1977 and 2015 were retained for the analysis. A pancreato-biliary involvement was recognized in 34 individually well-described patients (♂:♀ = 19:15) with severe abdominal pain: pancreatitis (N = 20), acalculous cholecystitis (N = 11), both pancreatitis and cholecystitis (N = 3)...

Data on prevalence of hepatitis E virus (HEV) in Malawi is limited. We tested blood samples from HIV-uninfected and -infected populations of women and men enrolled in research studies in Malawi during 1989-2008 to determine the seroprevalence of HEV, hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV). Samples were tested for IgG against HEV, total antibodies against HAV and HCV, and presence of HBV surface antigens. Of 800 samples tested, 16.5% were positive for HEV IgG, 99.6% were positive for HAV antibodies, 7...

BACKGROUND: As an important intermediate filament protein within liver cells, cytokeratin-18 (CK-18) has been confirmed as a potential indicator in various hepatitis progressions. OBJECTIVES: We sought to clarify the connection between serum CK-18 levels and hepatitis pathogenesis in the present meta-analysis. MATERIALS AND METHODS: With the application of various computerized databases, including PubMed, Embase, Cochrane Library, Google Scholar, Web of Science, China BioMedicine (CBM), China National Knowledge Infrastructure (CNKI), published papers that assessed the relationship between serum CK-18 levels and hepatitis were obtained...

Liver diseases are one of the leading causes of mortality in the world. The hepatic illnesses, which include inherited metabolic disorders, hemophilias and viral hepatitides, are complex and currently difficult to treat. The maturation of gene therapy has heralded new avenues for developing effective intervention for these diseases. DNA modification using gene therapy is now possible and available technology may be exploited to achieve long term therapeutic benefit. The ability to edit DNA sequences specifically is of paramount importance to advance gene therapy for application to liver diseases...

BACKGROUND: Multiple studies have recently proposed the lowering of upper limit of normal (ULN) for alanine aminotransferase (ALT) to improve the diagnostic sensitivity for viral hepatitides and metabolic syndrome (MS). We have tried to validate some of the proposed ULNs in the diagnosis of MS. METHODS: We used data from the HepaMeta Study conducted in 2011 in Slovakia, which explored the prevalence of MS in eastern Slovakia. Patients were tested for the criteria of MS and ALT...

AIM: To comparatively characterize clinical, biochemical, and hemostasiological parameters in patients with chronic alcoholic hepatitis (CAH) and chronic mixed hepatitis (CMH), i.e. CAH + chronic hepatitis C. SUBJECTS AND METHODS: Sixty-three patients (mean age 39.05±4.95 years) with chronic hepatitides of different etiology, who underwent general clinical, biochemical, and hemostasiological studies, were examined. RESULTS: The frequency and duration of major clinical symptoms were maximally pronounced in the patients with CMH...

The incidence of chronic viral hepatitides (CVH) has increased 2.2-fold in the Russian Federation over the past decade. This increase is mainly determined by an almost threefold rise in the incidence of chronic hepatitis C (CHC): from 12.9 in 1999 to 39.1 per 100,000 population in 2012. The calculated data of hepatitis C burden in the Russian Federation show that in 2010 the total medical and social losses and expenses associated with hepatitis C and its implications were 48.47 billion rubles or 0.108% of the gross domestic product, the direct medical costs were 17...

BACKGROUND: Ectopic hepatic lipid accumulation is closely related to the development of insulin resistance, which is regarded as one of the most significant risk factors of non-alcoholic fatty liver disease (NAFLD). The current study has shown that fat tissue constitutes an important endocrine organ with its own production and metabolism of many biologically active substances, among which adipokines play an important role. Classic adipokines (e.g. leptin, adiponectin, resistin) are fat-derived hormones which serum level is altered in patients with NAFLD...

BACKGROUND/AIMS: The incidence of hepatocellular carcinoma (HCC) in Mongolia is growing at an alarming rate. Traditional dried food was suggested as the major reason for high HCC numbers, due to possible aflatoxin contamination during manufacturing. We thus aimed to measure aflatoxin concentrations in Mongolian food samples. METHODS: Samples of traditional Mongolian food ('aaruul', dried meat, and dried noodles; in total 11 samples) were collected and shipped to Germany...
