Chronic Hepatitis C is a major public health problem. The chronicity of the Hepatitis C can lead to advanced liver disease, cirrhosis and even hepatocellular carcinoma. Chronic hepatitis C is the leading indication of for liver transplantation in the United States. Since the introduction of directly acting antiviral agents (DAAs), there have been there have been dramatic advances in treatment of hepatitis C in terms of tolerability, duration of therapy with significant increases in the rates of sustained virology response (SVR)...

BACKGROUND: Despite global efforts to control HIV among key populations, new infections among men who have sex with men (MSM) and transgender (TG) individuals are still increasing. The increasing HIV epidemic among MSM/TG in China indicates that more effective services are urgently needed. However, policymakers and program managers must have a clear understanding of MSM/TG sexual health in China to improve service delivery. To meet this need, we undertook a scoping review to summarize HIV epidemiology and responses among MSM and TG individuals in China...

Glycerol monolaurate (GML) is a monoglyceride with well characterized anti-microbial properties. Because of these properties, GML is widely used in food, cosmetics, and personal care products and currently being tested as a therapeutic for menstrual associated toxic shock syndrome, superficial wound infections, and HIV transmission. Recently, we have described that GML potently suppresses select T cell receptor (TCR)-induced signaling events, leading to reduced human T cell effector functions. However, how soluble host factors present in the blood and at sites of infection affect GML-mediated human T cell suppression is unknown...

OBJECTIVE: A recent HIV outbreak in a rural network of persons who inject drugs (PWID) underscored the intersection of the expanding epidemics of opioid abuse, unsterile injection drug use (IDU), and associated increases in hepatitis C virus (HCV) infections. We sought to identify US communities potentially vulnerable to rapid spread of HIV, if introduced, and new or continuing high rates of HCV infections among PWID. DESIGN: We conducted a multistep analysis to identify indicator variables highly associated with IDU...

Astroglia are indispensable component of the tripartite synapse ensheathing innumerous soma and synapses. Its proximity to neurons aids the regulation of neuronal functions, health and survival through dynamic neuroglia crosstalk. Susceptibility of astrocyte to HIV-1 infection and subsequent latency culminates in compromised neuronal health. The viral protein HIV-1 transactivator of transcription (Tat) is neurotoxic. HIV-1 Tat is detected in brain of AIDS patients even in cases where viral load is non-detectable due to successful HAART therapy...

Kemerovo Oblast (KO) has had the highest rate of HIV spread in Russia since 2011. The aim of this work was to study the genetic variation of HIV-1 in Kemerovo Oblast. Blood was sampled from a total of 91 HIV-positive antiretroviral-therapy-naïve individuals in 2013 (38) and 2015 (53). HIV-1 subtypes, pol gene drug resistance mutations, and viral tropism were analyzed. In 2013-2015, the prevalence of HIV-1 subtype A decreased in KO from 60.5 to 7.5 %. The samples collected in 2015 from the patients with newly diagnosed HIV demonstrate the current dominance of HIV-1 CRF63_02A1 (71...

Unlike in most of the world, HIV incidence in the former Soviet Union continues to rise. While international labor migration has been identified as a potentially important contributor to this trend, most attention has been focused on risks of male migrants themselves. This study uses recent household survey data to examine HIV-related perceptions and actions of migrants' left-behind wives in Armenia. Multivariate logistic regression analyses show that migrants' wives are significantly more likely to suspect their husbands of extramarital sex than are non-migrants' wives...

The aim of the study was to identify factors associated with undiagnosed human immunodeficiency virus (HIV) infection among men who have sex with men (MSM) and male-to-female transgender women in Lima, Peru.We analyzed characteristics of 378 MSM and transgender women recruited from 2 sexually transmitted infection (STI) clinics in Lima, Peru. Descriptive analyses compared: (A) HIV-uninfected, (B) previously undiagnosed HIV-infected, and (C) previously diagnosed HIV-infected participants. Multivariable logistic regression models identified: (1) correlates of previously undiagnosed HIV-infection among participants thought to be HIV-uninfected (B vs A); and (2) correlates of previously undiagnosed HIV-infection among HIV-infected participants (B vs C)...

PURPOSE OF REVIEW: To review the newest research about the effects of combination antiretroviral therapy (cART) on cancer risk. RECENT FINDINGS: HIV+ persons are at increased risk of cancer. As this risk is higher for malignancies driven by viral and bacterial coinfections, classifying malignancies into infection-related and infection-unrelated has been an emerging trend. Cohorts have detected major reductions in the incidence of Kaposi sarcoma and non-Hodgkin lymphoma (NHL) following cART initiation among immunosuppressed HIV+ persons...

PURPOSE OF REVIEW: The present review summarizes the association of the different histotypes of Epstein-Barr virus (EBV)-associated lymphomas with known genetic lesions and/or oncogenic viruses. A more comprehensive understanding of the complex interplay existing between genetic abnormalities of tumor cells and the viral contribution to the development of EBV-associated lymphomas is pivotal for the development of more effective treatments. RECENT FINDINGS: Recent evidence indicates that HIV may contribute to lymphomagenesis by acting directly on B lymphocytes as a critical microenvironmental factor...

PURPOSE OF REVIEW: Eastern Europe and Central Asia (EECA) has experienced large-scale epidemics of syphilis, hepatitis C virus (HCV) and HIV over the past few decades. Here, we review recent evidence on the epidemiology of and the response to these intersecting epidemics. RECENT FINDINGS: The HIV epidemic in EECA continues to expand, with new infections increasing by more than 50% between 2010 and 2015. HCV is now in the top 10 causes of death in EECA, with Russia accounting for more than half of the global burden of HCV infections, but access to direct-acting antivirals remains a major obstacle for control of the epidemic...

OBJECTIVE: HIV-1 reservoirs are the major hurdle to virus clearance in cART-treated patients. An approach to eradicating HIV-1 involves reversing latency in cART-treated patients in order to make latent cells visible to the host immune system. Stimulation of patient cell cultures with LRAs ex vivo results in heterogeneous responses among HIV-infected patients. Determinants of this heterogeneity are unknown and consequently, important to determine. DESIGN AND METHODS: Here, we grouped and retrospectively analyzed the data from our two recent HIV-1 reactivation studies to investigate the role of the HIV-1 reservoir size in the reactivation capacity by LRAs in ex vivo cultures of CD8-depleted PBMCs isolated from 54 cART-treated patients and of resting CD4 T cells isolated from 30 cART-treated patients...

HIV-1 infection is associated with substantial damage to the gastrointestinal (GI) tract resulting in structural impairment of the epithelial barrier and a disruption of intestinal homeostasis. The accompanying translocation of microbial products and potentially microbes themselves from the lumen into systemic circulation has been linked to immune activation, inflammation, and HIV-1 disease progression. The importance of microbial translocation in the setting of HIV-1 infection has led to a recent focus on understanding how the communities of microbes that make up the intestinal microbiome are altered during HIV-1 infection and how they interact with mucosal immune cells to contribute to inflammation...

PURPOSE OF REVIEW: Cancer is a growing problem in the HIV population, in large part because of aging of HIV-infected people treated with antiretroviral therapy. Overall and cancer-specific survival is worse in HIV-infected cancer patients compared with uninfected patients. One potential reason for the observed survival deficit is differences in cancer treatment. RECENT FINDINGS: Recent population-based data suggest that HIV-infected cancer patients are less likely to receive cancer treatment compared with uninfected patients...

Here we reported two patients who presented with panuveitis and were transferred from ophthalmologists to rheumatologists, for both the patients had oral and genital ulcers. They were misdiagnosed with Behcet's disease at first glance. Two young males presented with acute uveitis with history of recurrent oral and genital ulcers. They initially presented with symptoms and signs resembling Behcet's disease and were treated with systemic steroids with suboptimal responses. Routine laboratory test revealed syphilis and human immunodeficiency virus (HIV) infection...

The pathogenesis of classical Hodgkin lymphoma (cHL) is still enigmatic, largely because its tumor cells, the so-called Hodgkin and Reed-Stenberg (HRS) cells, invariably reside in a prominent reactive microenvironment, are rare and therefore difficult to analyze. On the other hand, the broadly investigated cHL-derived cell lines are not unequivocally considered as suitable and representative models for this puzzling disease. Based on current knowledge, it appears that the cross talk between the tumour cells and the reactive infiltrate of the microenvironment is complex and that multiple mechanisms occur, making cHL a very heterogeneous disease...

Changes in retrovirus acquisition/transmission behaviors have been reported in Brazil, with a concerning increase in HIV-1 infected individuals aged 15 to 39 years. In São Paulo, HIV-1/HTLV-1 and HIV-1/HTLV-2 coinfections have been associated with intravenous drug use and failure to detect HTLV-1/2 with immunosuppression and the use of active antiretroviral therapy (HAART). Negative results for HTLV serologic [western blotting (WB)] and molecular [real-time PCR pol (qPCR)] confirmatory assays have been reported, whereas the best sensitivity has been found for INNO-LIA (LIA)...

Elevated CD8 counts with combination antiretroviral therapy (cART) initiation may be an early warning indicator for future treatment failure. Thus, we investigated whether elevated CD8 counts were associated with virological failure (VF) in the first 4 years of cART in Asian HIV-infected patients in a multicenter regional cohort.We included patients from the TREAT Asia HIV Observational Database (TAHOD). Patients were included in the analysis if they started cART between 1996 and 2013 with at least one CD8 measurement within 6 months prior to cART initiation and at least one CD8 and viral load (VL) measurement beyond 6 months after starting cART...

PURPOSE OF REVIEW: The present review will discuss recent advances in the development of anti-HIV therapies inspired by studies of the mechanisms of host restriction factor-mediated resistance to HIV infection. RECENT FINDINGS: Manipulating the interplay between host cell restriction factors and viral accessory factors that overcome them can potentially be therapeutically useful. Preliminarily successful therapies - some of which are entering clinical trials - either inhibit the ability of virus to evade restriction factor-mediated immunity, or promote intracellular levels of restriction factors...
