Since the worldwide introduction of antiretroviral therapy (ART) in human immunodeficiency virus type 1, HIV-1-positive mothers, together with HIV-1 testing prior to pregnancy, caesarian birth and breastfeeding cessation with replacement feeding, a reduction of HIV-1 mother-to-child transmission (MTCT) has been observed in the last few years. As such, an increasing number of children are being exposed in utero to ART. Several questions have arisen concerning the neurological effects of ART exposure in utero, considering the potential effect of antiretroviral drugs on the central nervous system, a structure which is in continuous development in the fetus and characterized by great plasticity...

The introduction of generic antiretroviral medications in developing countries has resulted in significant CD4 cell restoration, HIV viral decline, and a noteworthy reduction in the time to initiation of therapy. Projection models have also predicted significant cost saving associated with the extensive diffusion of generic antiretrovirals in developed countries. However, some uncertainties on generics have recently been raised. These concerns mainly relate to the adequacy of the study design for bioequivalence testing, the potential for uncontrolled switching from one generic to another, and the loss of adherence if patients switched from fixed-dose coformulations to single components in order to incorporate the new generic drugs...

HIV/AIDS remains a major public health issue. In 2014, it was estimated that 36.9 million people are living with HIV worldwide, including 2.6 million children. Since the advent of combination antiretroviral therapy (cART), in the 1990s, treatment has been so successful that in many parts of the world, HIV has become a chronic condition in which progression to AIDS has become increasingly rare. However, while people with HIV can expect to live a normal life span with cART, lifelong medication is required and cardiovascular, renal, liver, and neurologic diseases are still possible, which continues to prompt research for a cure for HIV...

Reverse transcription of viral RNA and the subsequent integration of reverse transcripts are the classical early events of the HIV-1 life-cycle. Simultaneously, abundant unintegrated DNAs (uDNAs), are formed in cells ubiquitously. The uDNAs either undergo recombination or degradation or persist inactively for long periods in the nucleus as future resources. Among them, 2-LTR circles are considered a dead-end for viral spread. Their contribution to the HIV-1 infection is still poorly understood. Nevertheless, the preintegration transcription of the aberrant DNAs and the consequent alterations of cellular factors have already been reported...

INTRODUCTION: HIV testing and counselling (HTC) interventions are key to controlling the HIV epidemic in East and Southern Africa where HTC is primarily delivered through voluntary counselling and testing (VCT), provider initiated testing and counselling (PITC), and home-based counselling and testing (HBVCT). Decision making processes around uptake of HTC models must be taken into account when designing new interventions. Counselling in HTC aims to reduce post-test risk taking behaviour and to link individuals to care but its efficacy is unclear...

BACKGROUND: A surge in mobile phone availability has fueled low cost short messaging service (SMS) adherence interventions. Multiple systematic reviews have concluded that some SMS-based interventions are effective at improving antiretroviral therapy (ART) adherence, and they are hypothesized to improve retention in care. The objective of this study was to evaluate the cost-effectiveness of SMS-based adherence interventions and explore the added value of retention benefits. METHODS: We evaluated the cost-effectiveness of weekly SMS interventions compared to standard care among HIV+ individuals initiating ART for the first time in Kenya...

RATIONALE: Chronic liver disease is a major cause of morbidity and mortality in patients with HIV. However, autoimmune hepatitis (AIH) in patients with HIV has rarely been reported. Our aim was to evaluate a cohort of patients with HIV and AIH and identify clinical presentations and outcomes. PATIENT CONCERNS: Management of autoimmune hepatitis in context of human immunodeficiency virus, long-term outcomes, and safety in setting of underlying immunocompromised state...

PURPOSE OF REVIEW: The importance of IgG Fc-effector functions for the efficacy of HIV vaccines is increasingly recognized. Although different types of vaccines were shown to induce antibodies with different Fc-activities, there is no clear strategy how to raise antibody responses with a desired pattern of Fc-effector functions. Given the central role of T-helper cells in regulating the germinal center reaction and the differentiation of B cells in an antigen-specific manner, the review will discuss whether T-helper cells directed against non-HIV envelope (Env) antigens could be harnessed to improve the HIV-Env antibody response...

PURPOSE OF REVIEW: An HIV-1 vaccine that elicits broadly neutralizing antibodies (bNAbs) remains to be developed. Here, we review how knowledge of bNAbs and HIV-1 entry mechanism is guiding the structure-based design of vaccine immunogens and immunization regimens. RECENT FINDINGS: Isolation of bNAbs from HIV-1-infected donors has led to an unprecedented understanding of the sites of vulnerability that these antibodies target on the HIV-1 envelope (Env) as well as of the immunological pathways that these antibody lineages follow to develop broad and potent neutralization...

PURPOSE OF REVIEW: Since 2009 many broadly neutralizing antibodies against HIV have been identified, yet there is still no vaccine capable of inducing such antibodies in humans. This review considers the early observations of HIV sera neutralization in light of more recent studies and highlights areas for future research. RECENT FINDINGS: Large clinical cohort studies using standardized neutralization assays and pseudoviruses derived from primary isolates have shown that 10-30% of HIV infections result in some level of serum neutralization breadth...

PURPOSE OF REVIEW: Although approximately 90% of all HIV transmissions in humans occur through mucosal contact, the induction of mucosal anti-HIV immune responses has remained understudied. Here we summarize data demonstrating the powerful protection that is achievable at mucosal frontlines through virus-specific mucosal IgA alone or combined with IgG. RECENT FINDINGS: Passive immunization with different monoclonal antibody subclasses but identical epitope specificity (the conserved V3-loop crown of HIV gp120) has revealed that the dimeric IgA1 (dIgA1) form with its open hinge can prevent simian-human immunodeficiency virus (SHIV) acquisition in rhesus macaques at a higher rate than dIgA2...

PURPOSE OF REVIEW: A major focus in HIV vaccine research is the development of suitable antigens that elicit broadly neutralizing antibody responses targeting HIV's envelope protein (Env). Delivery of Env in a repetitive manner on particle-based carriers allows higher avidity interactions and is therefore expected to efficiently engage B cells, thus leading to affinity maturation that results in superior antibody responses characterized by improved breadth, potency, and durability. This review summarizes current work that is evaluating diverse types of such particulate carriers for Env delivery...

BACKGROUND: Mental health and HIV disparities are well documented among sexual minorities, but there is a dearth of research on other chronic conditions. Cardiovascular disease remains the leading cause of death worldwide. Although sexual minorities have high rates of several modifiable risk factors for cardiovascular disease (including stress, tobacco use, and alcohol consumption), there is a paucity of research in this area. OBJECTIVES: In this systematic review, we synthesized and critiqued the existing evidence on cardiovascular disease among sexual minority adults...

Composite lymphoma (CL) is a rare disease with 2 distinct lymphomas concurrently arising in a single patient with an estimated incidence of 1-4.7% of newly diagnosed lymphomas per year. CL most commonly involves 2 B-cell non-Hodgkin lymphomas (NHL) or a B-cell NHL with a Hodgkin lymphoma. Our case is unique in that it was a bilineage CL with both a T-cell and B-cell NHL, which has only been reported in a few case reports. A 49-year-old woman presented with several months of progressive cough, weight loss, dyspnea, and supraclavicular lymphadenopathy...

Cervical cancer (CC) is a leading cause of cancer-related death and a major public health issue in sub-Saharan Africa. This heavy burden parallels that of the human immunodeficiency virus (HIV) infection, which increases the risk of developing CC. Despite the progressive reduction of HIV prevalence in the past decade, the CC incidence and mortality rates in sub-Saharan Africa remain high. The heterogeneity of the distribution of the two diseases in the African continent, together with the different availability of human and material resources, stands in the way of finding an appropriate screening strategy...

During the HIV/AIDS epidemic of the 1980s, most of the developed world instituted a permanent ban on blood donations from men who have sex with men (MSM). In recent years, public health agencies across Europe and North America are reconsidering and rescinding these restrictions. We examine the Canadian climate, where MSM may donate blood only after a 5-year deferral period. We review circumstances of the initial ban on MSM blood donations and recent social, legal, and economic changes that have encouraged Canadian public health officials to consider policy reform...

The aetiology of epididymo-orchitis is largely related to a patient's age with sexually transmitted pathogens being the common aetiological agents in those below 35 years of age. In individuals aged over 35, uropathogens represent the commonest cause. National guidelines exist for the appropriate management of this condition and its varying aetiology. We aimed to assess the management of epididymo-orchitis in our clinic with reference to the British Association for Sexual Health and HIV national guidelines...

Human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) is a multisystem disease that can involve the human eyes. Using ophthalmic examination records from January 2006 to November 2015, we retrospectively reviewed all patients who were diagnosed with HIV/AIDS in our hospital. The study was performed at a tertiary referral center in southern Taiwan. Data included age, gender, ophthalmic examinations, systemic conditions, CD4 cell counts, course, and treatment. Eleven patients were identified as having AIDS with uveitis as their presenting manifestation...
