BACKGROUND: Few low-income countries have virological monitoring widely available. We estimated the virological durability of first-line antiretroviral therapy (ART) after five years of follow-up among adult Ugandan and Zimbabwean patients in the DART study, in which virological assays were conducted retrospectively. METHODS: DART compared clinically driven monitoring with/without routine CD4 measurement. Annual plasma viral load was measured on 1,762 patients. Analytical weights were calculated based on the inverse probability of sampling...

BACKGROUND: In hepatitis B virus (HBV) infected patients, hepatitis B e antigen (HBeAg) seroconversion is associated with better outcomes. Interleukin-18 (IL-18) controls hepatitis B replication in a mouse model. However, its role in treatment response in HIV/HBV co-infected patients is unknown. METHODS: We enrolled 35 treatment-naïve, HBeAg positive, HIV/HBV co-infected patients. HBV DNA, HIV RNA, CD4 cell count, HBV surface antigen (HBsAg) quantification (qHBsAg), HBeAg quantification (qHBeAg) and IL-18 levels were measured prior to, at 24 and 48 weeks of HBV-active combination antiretroviral therapy (cART)...

BACKGROUND AND AIM: Tenofovir disoproxil fumarate (TDF) is recommended as first-line monotherapy for nucleos(t)ide (NA)-naïve chronic hepatitis B (CHB) patients and as a second-line rescue therapy for NA-experienced patients with a previous treatment failure. However, data regarding the efficacy of TDF monotherapy in patients with lamivudine resistance (LAM-R) successfully treated with LAM+adefovir (ADV) are limited. Herein, the efficacy and safety of switching from LAM+ADV to TDF monotherapy in clinical practice have been evaluated...

The complicated replication mechanisms of hepatitis B virus (HBV) have impeded HBV studies and anti-HBV therapy development as well. Herein we report efficient genome replication of HBV applying adenovirus vectors (AdVs) showing high transduction efficiency. Even in primary hepatocytes derived from humanized mice the transduction efficiencies using AdVs were 450-fold higher compared than those using plasmids. By using an expression unit consisting of the CMV promoter, 1.03-copy HBV genome and foreign poly(A) signal, we successfully generated an improved AdV (HBV103-AdV) that efficiently provided 58 times more pregenomic RNA than previously reported AdVs...

In patients with lymphoma the detection of positive hepatitis B or C viruses (HBV and HCV) serology involves crucial therapeutic consequences. In HBV-infected patients the serological profile of active (HBsAg-positive) or resolved (HBsAg-negative/anti-HBcAb-positive) infection is associated to differential risk of viral reactivation during rituximab-based therapy and require appropriate strategies of monitoring and of antiviral prophylaxis. In HCV-associated NHL patients consolidated data demonstrated that interferon (IFN)-based antiviral therapy (AT) is able to induce lymphoma regression strictly related to viral eradication, while preliminary data of the new direct-acting antivirals (DAAs) are very promising...

A highly efficient [1,2]-Brook rearrangement of silyl glyoxylates has been developed using DBU as the organobase-catalyst. This [1,2]-Brook rearrangement is applicable to a number of thiols and secondary phosphine oxides containing acidic protons. These nucleophiles afford the corresponding Brook products in high yields. Using this methodology, a formal synthesis of anti-HIV drug compound lamivudine was realized.
