1/5. Gianotti-Crosti syndrome associated with endogenous reactivation of Epstein-Barr virus.A 6-year-old girl with Gianotti-Crosti syndrome, which appeared to be caused by a reactivation of Epstein-Barr virus (EBV), is presented. The patient had had infectious mononucleosis at the age of 3 years. Since the titer of anti-EBV capsid antigen antibody was high at 1,280 and the titer of early antigen DR IgG, which increases during the early stage or reactivation, was high at 80 during the recovery stage, the patient was diagnosed as having Gianotti-Crosti syndrome associated with reactivation of EBV. Its clinical symptoms associated with reactivation of EBV were similar to those of that associated with primary EBV infection, in that the present patient had acrolocated papulovesicular dermatitis, superficial lymph node enlargement and mild hepatopathy. This patient provides valuable information in that reactivation was also observed with EBV like other types of herpesvirus.- - - - - - - - - - ranking = 1keywords = herpesvirus (Clic here for more details about this article) |
2/5. Human herpesvirus 8-related childhood mononucleosis: a series of three cases.Human herpesvirus 8 has been implicated in the pathogenesis of a limited subset of lymphoproliferative disorders in adults, but its role in children is unclear. A prospective evaluation of children with atypical lymphocytosis residing in the Hualien area, where the incidence of adult Kaposi sarcoma is high, revealed 3 cases caused by human herpesvirus 8.- - - - - - - - - - ranking = 6keywords = herpesvirus (Clic here for more details about this article) |
3/5. Mononucleosis-like illness in an infant associated with human herpesvirus 6 infection.Illnesses resembling mononucleosis, hematologically characterized by atypical lymphocytosis in the peripheral blood, are caused by other viral infections as well as by a primary Epstein-Barr virus infection. Human herpesvirus 6, a newly isolated member of the herpesvirus group, can also cause a mononucleosis-like illness. Illness associated with human herpesvirus 6 infection mostly occurs in immunocompetent adults. We observed a 3 month old infant who presented with marked atypical lymphocytosis and liver dysfunction. We examined serum samples to detect viral antibodies related to mononucleosis-like illness. Only the titers of antibody against human herpesvirus 6 were elevated. Primary human herpesvirus 6 infection cannot only cause exanthem subitum or present in an inapparent form but can also cause an illness like mononucleosis, even in an infant.- - - - - - - - - - ranking = 9keywords = herpesvirus (Clic here for more details about this article) |
4/5. Isolation of human herpesvirus 7 from a child with symptoms mimicking chronic Epstein-Barr virus infection.Human herpesvirus-7 (HHV-7), which is a newly identified human herpesvirus with an unknown pathologic role, was isolated from a 5-year-old boy suffering from fever, hepatosplenomegaly and pancytopenia. Although the clinical course was similar to that of chronic active Epstein-Barr virus infection, no viruses other than HHV-7 were isolated. This finding raises the possibility that HHV-7 played a pathogenic role in the present patient.- - - - - - - - - - ranking = 6keywords = herpesvirus (Clic here for more details about this article) |
5/5. Mononucleosis syndrome and coincidental human herpesvirus-7 and Epstein-Barr virus infection.Two girls (a 5 year old and a 21 month old) experiencing mononucleosis syndrome with coincidental human herpesvirus (HHV)-7 and Epstein-Barr virus (EBV) infections are described. One patient had primary HHV-7 infection and reactivated EBV infection. The other had primary HHV-7 and EBV infections. These cases indicated that HHV-7 is capable of inducing infectious mononucleosis-like illness. Multiple herpesvirus infection in one of the patients also suggests that interaction among herpesviruses can occur in vivo. The consequence of this interaction may have clinical implications.- - - - - - - - - - ranking = 7keywords = herpesvirus (Clic here for more details about this article) |
