Immune reconstitution hepatitis in HIV and hepatitis B coinfection, despite lamivudine therapy as part of HAART.

Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) coinfection occurs commonly. The introduction of antiretroviral therapy can result in immune reconstitution hepatitis. We describe 2 coinfected patients who developed clinical flares of HBV disease, despite the inclusion of lamivudine, a drug with anti-HBV activity, in their HAART regimens. Potential strategies to manage individuals with HBV/HIV coinfection are discussed.

Molecular analysis of clinical isolates of acyclovir resistant herpes simplex virus.

We characterised the antiviral phenotype and genotype of 41 herpes simplex virus (HSV) strains from patients clinically resistant to acyclovir (ACV). Our results confirm recognised mutational sites as being major determinants of thymidine kinase (tk)-associated ACV resistance, in particular insertions and/or deletions at homopolymer stretches of Gs and Cs (59% of all isolates). Previously described amino acid substitutions in functional sites of the tk were also identified (7% of all isolates). In addition, we identified several stop codons in novel locations on the amino acid sequence (7% of all isolates) and amino acid substitutions (15% of all isolates) likely to be directly responsible for conferring resistance to ACV. When there were no mutations detected in the tk gene (12% of all isolates), mutations in the DNA polymerase gene likely to be important in the generation of resistant virus were identified.

Hepatitis C and pregnancy: an update.

Hepatitis C is a slowly progressive disease with significant long-term sequelae including cirrhosis, liver failure and hepatocellular carcinoma. Many women of childbearing years are infected with this virus and are at risk of transmitting it to their offspring. Despite this, there are many unanswered questions about hepatitis C and pregnancy including who to screen, the risk factors associated with infection, how these women should be managed during pregnancy and the options available to them after delivery.
