BACKGROUND Prozone phenomenon is seen with very high-titer antibodies in an immune serum. AIM The prozone effect on anti-D by a low-titer anti-Lea was investigated associated with neonatal jaundice. MATERIALS AND METHODS Standard methods were used in investigations. RESULTS The child was born at full-term developed mild jaundice. With weak direct antiglobulin test+, her indirect serum bil...
A modified rubella virus plaque neutralization test for measuring rubella antibody was developed based on the potentiation of the virus-antibody complex by heterologous anti-immunoglobulin. The test is highly sensitive, yielding titers on the average 50 to 100 times higher than the haemagglutination inhibition test or the conventional plaque neutralization test. The sensitivity of this enhanced...
We describe a case of multiple myeloma (MM) and secondary plasma cell leukemia (PCL) secreting IgE-kappa immunoglobulin. To our knowledge, only 2 cases of IgE-producing secondary PCL have been reported in the medical literature. In our patient, the only tumor marker available for monitoring the therapeutic response to chemotherapy and allogeneic stem cell transplantation was the quantitative M ...
We describe a case of acute liver failure caused by echovirus 25 (E25) in a previously healthy 2-year-old boy. Initial serological studies were consistent with hepatitis A virus (HAV), with prozone phenomenon. The similarity of E25 to HAV may obscure accurate diagnosis in some cases of hepatitis.
