Non-A, non-B hepatitis Download PDF EPUB FB2
Hepatitis C, previously known as “non-A, non-B hepatitis,” was associated with a lifetime risk of 7% to 10% in transfusion recipients in the late s and early s.
44 The transmission rate of hepatitis C has decreased with improved screening tests to identify the virus, providing an excellent example of how implementation of each new generation of screening technology has improved blood safety.
Abstract. More than a decade has elapsed since the existence of a new type of posttransfusion hepatitis was postulated 1 and confirmed. 2 Provisionally designated non-A, non-B (NANB) hepatitis by exclusion of the two known virus types, a causative agent(s) has not yet been found and the original name is still valid.
However, a wealth of information, both positive and negative, has been Author: Victor M. Villarejos. Abstract. Disease: Non-A hepatitis, non-B hepatitis. Etiologic Agents: Diagnosis based on exclusion; the viral agents causing the parenterally transmitted forms of the infection have not been identified; the enterically transmitted epidemic form appears to be caused by a calici-like virus which has not yet been fully characterized.
Clinical Manifestations: Clinically similar to other types of Cited by: 1. Evidence for the existence of hepatitis non-A, non-B includes epidemiologic data and results of transmission studies indicating the presence of hepatitis that could not be explained by known causative agents.
The diagnosis is suggested in patients who have multiple episodes of acute hepatitis or who contract hepatitis after transfusion, hemodialysis or drug : C.
Feinman, B. Berris, J. Sinclair, D. Wrobel. From Novemthrough J17 cases of non-A,non-B (NANB) hepatitis were reported to the Wabash County (Illinois)Health Department. In Wabash County, a small rural county in southernIllinois (estimated population: 13,), only one other case ofNANB hepatitis had been reported since Non-A, non-B hepatitis: Dead ends or Non-A horizons.
Article Literature Review (PDF Available) in British Medical Journal (Clinical research ed.) () November with 25 Reads. The epidemiology of such non A, non B hepatitis resembles that of type A disease. Type non A, non B hepatitis can progress to a chronic state. Attempts to identify an antigen specific for non A.
Hepatitis C, formerly called non-A, non-B hepatitis, is also Non-A by contaminated blood transfusions and by sharing of needles among drug abusers, although in many cases no source can be identified. It is the most common form of chronic liver disease in the United States.
Interfering with Non-A, Non-B Hepatitis While scientists hunted for the mysterious agent behind non-A, non-B hepatitis, they also concentrated efforts on its treatment.
Because the virus was still unknown, the first drugs to be tested were those that had been shown to be effective against a broad range of viruses. The term "non-A, non-B hepatitis" is applied to cases of what appears to be viral hepatitis that cannot be identified as hepatitis A, hepatitis B or with the hepatitis associated with Epstein Barr virus and by: 7.

Medical Dictionary for the Health Professions and Nursing © Farlex Gary Gitnick, MD; Non-A, Non-B Hepatitis: Etiology and Clinical Course, Laboratory Medicine, Vol Is 1 NovemberPages –, by: Formerly called hepatitis non-A, non-B, this liver disease is caused by a small single-stranded RNA virus, 30–38 nm in diameter known as the hepatitis C virus (HCV).
The disease occurs world-wide and is spread mainly by intravenous drug abuse, tattooing, needle-stick injuries, inadequately-sterilized medical equipment and transfusion of blood.

Testing of serum samples from these recipients with hepatitis showed no evidence of hepatitis B virus or hepatitis A virus infection. This study and other recent evidence suggest that there is a third type of human viral hepatitis—non-A, non-B hepatitis—which is due to a transmissible agent and may well be associated with a chronic carrier Cited by: Vol.
3, No. 5, NON-A, NON-B HEPATITIS fected chimpanzees. They raise the interesting possibility that 6 and NANB hepatitis are quite similar in nature. The evidence for this concept is provided by the facts that 6 and NANB hepatitis agents produce similar his- tologic changes in the liver distinct from HAV and HBV,Cited by: 6.
Hepatitis E virus (HEV), formerly classified as one of the forms of ‘non-A, non-B’ hepatitis viruses, is an nonenveloped, single-stranded RNA virus. Viral particles measure approximately 27–34 nm in diameter and have spiky outlines.

Sham-extracted non-A, non-B hepatitis agent-containing plasma was shown to maintain its infectivity in chimpanzees that had initially been inoculated with the chloroform-extracted plasma. Thus, both hepatitis type B and non-A, non-B hepatitis appear to be caused by viruses that can be inactivated by a.

pp Abstract: A review with 17 references. Record Number: Cited by: Non-A-E hepatitis, sometimes referred to as hepatitis X, is a disease of the liver that is diagnosed when there is swelling of the liver but examination and testing does not identify a cause.
Symptoms of non-A-E hepatitis may include feeling tired or unwell (), nausea, vomiting, pain in the abdomen, and fever.
Non-A-E hepatitis usually goes away on its own, but it can become a chronic.
