Varicella-zoster hepatitis

In advanced AIDS, MM is usually associated with opportunistic infections such as CMV (Said et al. 1991 RouUet et al. 1994 Kolson and Gonzalez-Scarano 2001) or is secondary to lymphoma (Fuller et al. 1993). Despite a role for other herpes viruses in AIDS-associated myelitis, no substantive evidence has been published in support of a role for other vimses in the development of HIV-associated MM, including herpes simplex 1 or 2, varicella zoster, or Epstein Barr vims (Kolson and Gonzalez-Scarano 2001). MM can occur secondary to hepatitis B and C viruses, which are common co-infections of HIV-infected patients, particularly when there is an associated cryoglobulinemia (Taillan et al. 1993 Caniatti et al. 1996). Rarely... 

Pharmacology Ganciclovir, a synthetic guanine derivative active against CMV, is an acyclic nucleoside analog of 2 -deoxyguanosine that inhibits replication of herpes viruses both in vitro and in vivo. Sensitive human viruses include CMV, herpes simplex virus (HSV)-I and -2, herpes virus type 6, Epstein-Barr virus, varicella-zoster virus, and hepatitis B virus.

Chickenpox in infancy and shingles in adults are caused by the same varicella-zoster virus. Very rarely and almost exclusively in immunosuppressed patients, concomitant hepatitis can occur with pronounced (mainly focal) hepatocellular necrosis, sometimes even with a fatal course. (37) Leucocytic portal and periportal infiltration can spread to the blood vessels and bile capillaries. Intranuclear inclusion bodies are present (s. fig. 23.2). Diagnosis is based on increased GPT, GOT, GDH and y-GT values as well as the presence of varicella IgM antibodies alternatively, pathogens can also be demonstrated in cultures. In children, a differential diagnosis of Reye s syndrome must be considered. As therapy in a severe course, aciclovir is indicated. (38-43)... 

Famciclovir is an oral prodrug of penciclovir, a selective antiviral drug with activity against Varicella zoster virus. Herpes simplex virus types 1 and 2, and Epstein-Barr virus, as well as human hepatitis B virus. 

Specific immunoglobulins, termed hyperimmune globulins, are derived from human donors known to have high titers of the desired antibody. Specific immunoglobulin preparations for use in infectious disease prevention include hepatitis B, rabies, tetanus. Varicella zoster, vaccinia, and cytomegalovirus immunoglobulin. 

Severe viral infections/reactivation that have been reported in patients given ritnximab have inclnded fnl-minant hepatitis B (18), parvovims-indnced red cell aplasia (15), and fatal Varicella zoster infection (19). There was a high incidence of reactivation of cytomegalovirus and V. zoster virus when rituximab was combined with high-dose chemotherapy in high-risk patients with non-Hodgkin s lymphoma (20). 

There have been three case reports of suspected reactivation of Varicella zoster through hepatitis A vaccine, influenza vaccine, and simultaneous administration of rabies and Japanese encephalitis vaccine (19). 

Human diploid cell lines have been utilized classically as in vitro hosts for the propagation of polio, mumps, rubella, cytomegalovirus, varicella-zoster, rabies, hepatitis A, respiratory syncytial virus, parainfluenza and many other viruses. Other uses in the biotechnology industry include large-scale cultivation for the production of various cellular products, such as human interferon beta.

Vidarabine Vidarabine is an adenine analog and has activity against HSV, VZV, and CMV. Its use for systemic infections is limited by rapid metabolic inactivation and by marked toxic potential. However, it has been used intravenously for severe HSV infections, including those resistant to acyclovir, and it also prevents the dissemination of varicella-zoster virus in immunocompromised patients. Vidarabine is used topically for herpes keratitis, but it has no effect on genital lesions. Toxic effects with systemic use include gastrointestinal irritation, paresthesias, tremor, convulsions, and hepatic dysfunction. Vidarabine is teratogenic in animals.

MMR, varicella zoster, influenza, hepatitis B, meningococcal, and tetanus-containing vaccines are linked to anaphylaxis. 

The development of nucleoside analogs for medicinal uses has had a marked impact on clinical chemotherapy, and numerous nucleoside analogs were successfully developed for the treatment of human immunodeficiency viruses (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), herpes simplex virus (HSV), cytomegalovirus (CMV), varicella zoster virus (VZV), and various cancers [1]. 

Viral infections that occur after transplantation are not limited to the lung. Herpes simplex infections are frequent early after the procedure, manifesting as oral vesicles or ulcerations. Less frequent is genital involvement by herpes simple virus, hepatitis or encephalitis. Herpes zoster and varicella reactivate in most patients, particularly if aciclovir prophylaxis is discontinued. Occasionally, severe cerebral arteritis or pneumonia caused by this virus may occur. CMV infection is frequent after transplantation and has to be regularly monitored by antigenemia and/or PCR for early treatment avoiding CMV disease. Epstein Barr virus (EBV) infection and EBV-associated lymphoproliferative disorders have also to be tested on a regular basis, especially in transplants with in...
