OBJECTIVES: Immune recovery following highly active antiretroviral therapy (HAART) is commonly assessed by the degree of CD4 reconstitution alone. In this study, we aimed to assess immune recovery by incorporating both CD4 count and CD4:CD8 ratio. DESIGN: Observational cohort study SETTING AND PARTICIPANTS: Clinical data from Chinese HIV-positive patients attending the largest HIV service in Hong Kong and who had been on HAART for ≥4 years were accessed. MAIN OUTCOME MEASURES: Optimal immune outcome was defined as a combination of a CD4 count ≥500/μL and a CD4:CD8 ratio ≥0...

BACKGROUND: Virtually all HIV-infected women in sub-Saharan Africa have evidence of Cytomegalovirus (CMV) infection and levels of specific anti-CMV IgG have been suggested to represent more intense reactivation of subclinical infection. Studies have also shown direct influence of CMV on lymphocytes. OBJECTIVE: The aim of this study was to determine if levels of anti-CMV specific antibodies could impact on the immunological response to antiretroviral treatment (ART) in HIV-infected pregnant women...

Puja Van Epps, Robert C Kalayjian
Persons living with HIV (PLWH) have accentuated risks for age-associated comorbidities. Compared to the general population, PLWH have a 2-fold higher risk of cardiovascular disease, a 3-fold increased risk of fracture, and a risk of kidney disease that is comparable to that in diabetes. Some comorbidities may present at younger ages than among the general population, suggesting the possibility of accelerated aging with HIV infection.

Humoral response to vaccination has been found to be inadequate in individuals infected with the human immunodeficiency virus (HIV). We retrospectively assessed antibody responses to three routinely recommended vaccines, against hepatitis B, hepatitis A and S. pneumoniae, in HIV-infected individuals. Data regarding age at HIV diagnosis, years of infection, sex, nationality, HIV mode of transmission, CD4 cell count, nadir CD4 count, plasma viral load, HIV stage, insurance status, educational level and treatment with Highly Active Antiretroviral Therapy (HAART) were collected...

HIV infection and antiretroviral therapy (ART) treatment exert diverse effects on adipocytes and stromal-vascular fraction cells, leading to changes in adipose tissue quantity, distribution, and energy storage. A HIV-associated lipodystrophic condition was recognized early in the epidemic, characterized by clinically apparent changes in subcutaneous, visceral, and dorsocervical adipose depots. Underlying these changes is altered adipose tissue morphology and expression of genes central to adipocyte maturation, regulation, metabolism, and cytokine signaling...

BACKGROUND: Early identification of virological failure (VF) limits occurrence and spread of drug-resistant viruses in patients receiving antiretroviral treatment (ART). Viral load (VL) monitoring is therefore recommended, but capacities to comply with this are insufficient in many low-income countries. Clinical algorithms might identify persons at higher likelihood of VF to allocate VL resources. OBJECTIVES: We aimed to construct a VF algorithm (the Viral Load Testing Criteria; VLTC) and compare its performance to the 2013 WHO treatment failure criteria...

REVIEW
Eric M L Williamson, Joseph R Berger
Progressive multifocal leukoencephalopathy (PML) is a rare, but serious, complication encountered in patients treated with a select number of disease-modifying therapies (DMTs) utilized in treating multiple sclerosis (MS). PML results from a viral infection in the brain for which the only demonstrated effective therapy is restoring the perturbed immune system-typically achieved in the patient with MS by removing the offending therapeutic agent or, in the case of HIV-associated PML, treatment with highly active antiretroviral therapies...

This review explores the association between pediatric human immunodeficiency virus (HIV) disclosure and health and related outcomes among children living with HIV. A multi-stage process was used to search for relevant articles on the ISI Web of Knowledge database. Fifteen articles met the inclusion criteria. Five major outcomes emerged from children's knowledge of their HIV-seropositive status: physical/physiological outcomes; adherence to antiretroviral therapy; psychosocial outcomes; sexual and reproductive health, including HIV prevention outcomes; and disclosure of status by the children...

Coccidioidomycosis causes substantial morbidity and mortality in endemic areas, and dissemination is frequent in patients with impaired cellular immunity such as AIDS. Immune reconstitution inflammatory syndrome (IRIS) is paradoxical clinical worsening after initiation of antiretroviral therapy (ART) in a patient with HIV and a simultaneous opportunistic infection (OI). Immune reconstitution inflammatory syndrome has been well described for a host of mycobacterial, viral, and fungal OIs and malignancies such as Kaposi sarcoma...

Background: Following a decade of provision of free antiretroviral therapy (ART) in India, a nationwide assessment of ART services was conducted to review quality of care at ART centers. This paper presents the methods and defines replicable model of undertaking large scale assessments. Methods: During the period January 2014-March 2015, 357 ART centers were reviewed under four domains, namely, operations, technical, monitoring and evaluation (M&E), and logistics...

Human immunodeficiency virus-1 (HIV-1) continues to be a major global public health issue and priority. Despite the variety of antiretroviral therapies, it seems that an effective vaccine against HIV-1 is still very necessary. An ideal HIV-1 vaccine should be able to elicit both humoral and cellular immunities. In this respect, polyepitope vaccines, incorporated from several conserved regions of HIV-1 proteins, have received much attention recently. Herein, the immunogenicity of the HIV-1 polyepitope protein-based candidate vaccines was evaluated in BALB/c mice...

BACKGROUND AND PURPOSE: Cardiovascular disease associated with antiretroviral therapy (ART) has become a major clinical challenge for HIV-positive patients. However, the role of ART in blood vessel growth is largely unknown. Here, we examined an integral component of ART, nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs), and investigated their effects on key microvascular functions, including angiogenesis and lymphangiogenesis. EXPERIMENTAL APPROACH: The angiogenesis/lymphangiogenesis capability of endothelial cells (ECs) was evaluated using migration, proliferation and tube formation assays in vitro, and mouse ear and Matrigel plug assays in vivo...

: Hepatitis B virus (HBV) reactivation has been documented in association with multiple immunotherapy regimens . These reactivations can be life-threatening and result in fulminant hepatic failure. There are currently no reports of HBV reactivation on nivolumab treatment. This is a case of a patient with known HIV infection and previous HBV workup that revealed him to be anti-hepatitis B core antibody positive, hepatitis B surface antigen negative, and HBV DNA negative. He experienced a HBV reactivation while on therapy with nivolumab for stage IIIa poorly differentiated carcinoma of the lung, which was a recurrence from a prior surgically resected stage Ia well differentiated adenocarcinoma of the lung...

INTRODUCTION: Integrase strand transfer inhibitors (INSTI) are currently being investigated for the treatment of HIV in pregnancy. The purpose of this study is to evaluate the differences in maternal and infant outcomes in HIV-positive mothers treated with INSTI-containing antiretroviral therapy (ART) during pregnancy compared to protease inhibitor (PI)-containing ART. METHODS: A retrospective, cohort study of INSTI- and PI-based ART used in pregnancy between 2007 and 2015 was performed...

BACKGROUND: More and more HIV-1-infected men on effective antiretroviral treatment (ART) have unprotected sex in order to procreate. The main factor influencing transmission is seminal HIV shedding. While the risk of HIV transmission is very low, it is difficult to assess in individuals. Nevertheless, it should be quantified. RESULTS: We retrospectively analysed seminal plasma HIV-1 shedding by 362 treated HIV-infected men attending a medically assisted reproduction centre (1998-2013) in order to determine its frequency, the impact of the antiretroviral regimen on HIV shedding, and to identify shedding patterns...
