Abstract

Forty-four anti-HBc positive patients with various liver diseases were followed up over 2-3 years with enzyme-immunological determinations of the IgM fraction of anti HBc (anti-HBc-IgM). Patients with acute virus hepatitis B (n = 10) had anti-HBc-IgM titres greater than or equal to 10(-3) in the acute phase. In the reconvalescent phase the titre decreased significantly but was still detectable at a level of 10(-1) two years after the onset of the disease. In patients with HBs-antigen positive chronic active hepatitis (n = 25) the anti-HBc-IgM was always detectable when HBe-antigen was positive. Patients with HBe-antigen negative chronic active hepatitis B showed various anti-HBc-IgM findings. Patients with liver diseases not due to hepatitis B virus infections (n = 9) were always anti-HBc-IgM negative. Thus with the help of anti-HBc-IgM determinations acute hepatitis B virus infection can be diagnosed in HBs-antigen negative people. On the other hand it is not suitable for differentiation between acute and chronic hepatitis B infections in HBs-antigen positive persons.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Torsion Dystonia

Torsion dystonia is a movement disorder characterized by loss of control of voluntary movements appearing as sustained muscle contractions and/or abnormal postures. Here is the latest research.

Archaeal RNA Polymerase

Archaeal RNA polymerases are most similar to eukaryotic RNA polymerase II but require the support of only two archaeal general transcription factors, TBP (TATA-box binding protein) and TFB (archaeal homologue of the eukaryotic general transcription factor TFIIB) to initiate basal transcription. Here is the latest research on archaeal RNA polymerases.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Central Pontine Myelinolysis

Central Pontine Myelinolysis is a neurologic disorder caused most frequently by rapid correction of hyponatremia and is characterized by demyelination that affects the central portion of the base of the pons. Here is the latest research on this disease.
