Autonomic and Enteric Nervous System Dysfunction May Play a Role in Hyperemesis Gravidarum.

Background: Nausea and vomiting, seen in 70-85% of all pregnancies, becomes intractable in hyperemesis gravidarum (HG). We aimed to investigate the relationship between HG and autonomic nervous system functioning and gastric electrical activity.

Methods: Twenty-seven pregnant patients, 21 with HG and six normal, were studied with sympathetic adrenergic; percent vasoconstriction (%VC) and postural adjustment ratio (PAR); parasympathetic vagal cholinergic functions by R-to-R intervals (RRIs), a total autonomic score; and enteric nervous system measured by electrogastrography (EGG).

The induction of type I interferon production in hepatitis C-infected patients.

Chronic infection with hepatitis C virus (HCV) is a major global health problem. One way HCV may evade the host immune response is by inhibiting the production of type I interferon (IFN). In addition, the standard treatment for chronic HCV infection involves treatment with IFN-alpha (or its pegylated derivative), alone or in combination with ribavirin.

Sarcoidosis mimicking primary sclerosing cholangitis requiring liver transplantation.

Sarcoidosis is a systemic granulomatous disease of unknown etiology. The association of the cholestatic pattern usually seen in sarcoidosis, with biliary duct changes resembling primary sclerosing cholangitis (PSC) is rare. Liver transplantation permits the histological evaluation of the complete explanted liver, making the diagnosis more reliable.

Intraperitoneal rupture of ectopic varices: two case reports and a review of literature.

Intraperitoneal rupture of ectopic varices is a rare complication of portal hypertension. Few case reports have been published in the literature. We report 2 cases of ectopic varices with intraperitoneal hemorrhage.

Nonalcoholic fatty liver disease of obesity.

Nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH) are part of the same continuum. They are a major, under-recognized cause of chronic liver disease. Good medical treatment options do not exist to date.

Neuropsychiatric complications after liver transplantation: role of immunosuppression and hepatitis C.

Neuropsychiatric complications are an important source of morbidity following orthotopic liver transplantation. Etiology of liver disease and type of immunosuppression are possible related factors. The aim of this study was to describe the prevalence of neuropsychiatric complications after liver transplantation, the role of immunosuppression, and the association between these and specific liver diseases such as hepatitis C.

Overcoming obstacles to immunization in patients with chronic liver disease.

The importance of vaccination to protect against hepatitis A virus (HAV) and hepatitis B virus (HBV) infections in patients with chronic liver disease has been established. However, in this population, a number of obstacles can interfere with appropriate and timely hepatitis immunization. The costs of hepatitis A and B vaccine series are out of reach for many uninsured patients.

Reproduction and transplantation: report on the AST Consensus Conference on Reproductive Issues and Transplantation.

It has been almost 50 years since the first child was born to a female transplant recipient. Since that time pregnancy has become common after transplantation, but physicians have been left to rely on case reports, small series and data from voluntary registries to guide the care of their patients. Many uncertainties exist including the risks that pregnancy presents to the graft, the patient herself, and the long-term risks to the fetus.

Intrahepatic cholestasis of pregnancy.

Patients with ICP should be considered to have a high-risk pregnancy. Once the diagnosis of ICP is suspected, usually because of generalized pruritus, it should be confirmed by liver function tests, and other causes of cholestasis should be ruled out. Treatment with UDCA is effective in ameliorating the cholestasis and is especially useful in severe forms or when there is a history of sudden fetal death in a previous pregnancy.
