Frequency of hepatitis B surface antigen variants (HBsAg) in hepatitis B virus genotype B and C infected East- and Southeast Asian patients: Detection by the Elecsys ® HBsAg II assay
Nearly 250 million people worldwide have chronic hepatitis B virus (HBV) infection, which can lead to long-term complications, such as cirrhosis, liver failure and hepatocellular carcinoma [1,2]. HBV is differentiated into a number of genotypes, which are characterized by differences of>8% in genome sequence; 10 HBV genotypes (A –J) have been identified to date, with distinct geographic distributions [3]. For example, genotype C is primarily found in South-East Asia, and genotype I has been reported in Vietnam and Laos [3]. (Source: Journal of Clinical Virology)

Evaluation of the Architect HIV Ag/Ab Combo Assay in a low-prevalence setting: The role of samples with a low S/CO ratio
The complexity of the HIV-1 epidemic has been increasing worldwide, reaching a highly heterogeneous distribution of HIV-1 subtypes/sub-subtypes that varies geographically [1 –3]. On the other hand, the diagnosis of HIV infection has evolved considerably since the development of the first serological screening tests in 1985. Nowadays, the most widely used are fourth-generation ELISAs, which can detect both antigens (p24) and antibodies against HIV-1 and HIV-2. These as says have been extensively evaluated and have proven to have high sensitivity and specificity, thus narrowing the window period and enabling the detection ...

Molecular features of Hepatitis E Virus circulation in environmental and human samples
Hepatitis E virus (HEV) is suspected to be a food- and water- transmitted virus with a zoonotic cycle especially for HEV genotype 3 (HEV3) [1]. HEV1 and HEV2 are restricted to humans and transmitted through contaminated water in developing countries. HEV3 and HEV4 genotypes can infect humans, pigs and other mammals [2,3]. HEV5 and HEV6 were detected in wild boars in Japan and HEV7 in camels [4,5]. However, HEV circulation between human beings, animals and the environment remains misunderstood and has been investigated for the present study in North Eastern France where quite a high HEV prevalence in humans was observed [6]...

Resistance detected in PBMCs predicts virological rebound in HIV-1 suppressed patients switching treatment

Rare emergence of drug resistance in HIV-1 treatment-na ïve patients receiving elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide for 144 weeks
Combination antiretroviral therapy containing 3 HIV-1 antiviral drugs has been the cornerstone for the treatment of HIV-1 infection for over 2 decades, while the advent of once-daily single tablet regimens have simplified treatment and greatly improved the quality of life of people burdened by HIV-1 infection [1]. The single-tablet regimen studied here, comprising the 3 antiviral drugs elvitegravir (EVG or E), emtricitabine (FTC or F), and tenofovir alafenamide (TAF) as well as the pharmaco-enhancer cobicistat (C) (known as Genvoya ® or E/C/F/TAF), is one of the latest complete HIV-1 treatment to gain regulatory approval ...

HIV-1 non-R5 tropism correlates with a larger size of the cellular viral reservoir and a detectable residual viremia in patients under suppressive ART
The entry of human immunodeficiency virus type 1 (HIV-1) into target cells requires the use of at least one of two distinct surface chemokine co-receptors, CCR5 (R5) or CXCR4 (X4). Viruses may use R5 (R5-tropic viruses) or X4 (X4-tropic) individually or use both R5 and X4 (dual or mixed-tropic virus) [1 –3]. (Source: Journal of Clinical Virology)
