Surveillance Study to Determine the Trends in Acute Hepatitis A Among Panamanian Children

2014-08-27 03:12:18 | BioPortfolio


The purpose of this study is to collect epidemiological and clinical data to assess the vaccine impact and occurrence of confirmed acute hepatitis A cases in sentinel hospitals after the introduction of Havrix™ into the Expanded Program of Immunization.


This is an observational, prospective, multi-centre, sentinel based study in 3 hospitals in Panama. Hospitals are selected based on population density or hepatitis A disease burden.

The Pan American Health Organization (PAHO) definition for a possible case of acute hepatitis A are used for subjects aged between >1 month and <15 years.

Data regarding clinical and epidemiologic information are collected and serum samples are collected to test hepatitis A markers and determine if infection with hepatitis A virus has recently occurred.

Surveillance will be for a period of approximately 2.5 years from the date of study initiation.

Medical and Biotech [MESH] Definitions

The type species of the genus ORTHOHEPADNAVIRUS which causes human HEPATITIS B and is also apparently a causal agent in human HEPATOCELLULAR CARCINOMA. The Dane particle is an intact hepatitis virion, named after its discoverer. Non-infectious spherical and tubular particles are also seen in the serum.

Acute INFLAMMATION of the LIVER in humans; caused by HEPATITIS E VIRUS, a non-enveloped single-stranded RNA virus. Similar to HEPATITIS A, its incubation period is 15-60 days and is enterically transmitted, usually by fecal-oral transmission.

A defective virus, containing particles of RNA nucleoprotein in virion-like form, present in patients with acute hepatitis B and chronic hepatitis. It requires the presence of a hepadnavirus for full replication. This is the lone species in the genus Deltavirus.

A form of rapid-onset LIVER FAILURE, also known as fulminant hepatic failure, caused by severe liver injury or massive loss of HEPATOCYTES. It is characterized by sudden development of liver dysfunction and JAUNDICE. Acute liver failure may progress to exhibit cerebral dysfunction even HEPATIC COMA depending on the etiology that includes hepatic ISCHEMIA, drug toxicity, malignant infiltration, and viral hepatitis such as post-transfusion HEPATITIS B and HEPATITIS C.

INFLAMMATION of the LIVER in humans due to infection by VIRUSES. There are several significant types of human viral hepatitis with infection caused by enteric-transmission (HEPATITIS A; HEPATITIS E) or blood transfusion (HEPATITIS B; HEPATITIS C; and HEPATITIS D).
