BACKGROUND: Contraception helps to prevent unplanned pregnancies among human immune virus positive women. The contraceptive utilization status and associated factors were not well addressed in the study area. Therefore, this study aimed to assess utilization of contraceptives and associated factors among human immune virus positive reproductive age group women appearing at anti-retroviral therapy clinic at the University of Gondar Hospital, North West Ethiopia. METHOD: An institution based cross-sectional study was conducted among 397 systematically selected HIV positive reproductive age women who visited ART unit of the University of Gondar teaching referral hospital from January 8-20, 2014...

The availability of several methods to unambiguously mark individual cells has strongly fostered the understanding of clonal developments in hematopoiesis and other stem cell driven regenerative tissues. While cellular barcoding is the method of choice for experimental studies, patients that underwent gene therapy carry a unique insertional mark within the transplanted cells originating from the integration of the retroviral vector. Close monitoring of such patients allows accessing their clonal dynamics, however, the early detection of events that predict monoclonal conversion and potentially the onset of leukemia are beneficial for treatment...

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...

The battle with human immunodeficiency virus (HIV) has been ongoing for more than 30 years, and although progress has been made, there are still significant challenges remaining. A few unique features render HIV to be one of the toughest viruses to conquer in the modern medicine era, such as the ability to target the host immune system, persist by integrating into the host genome and adapt to a hostile environment such as a single anti-HIV medication by continuously evolving. The finding of combination anti-retroviral therapy (cART) about 2 decades ago has transformed the treatment options for HIV-infected patients and significantly improved patient outcomes...

Cardiovascular events due to decompensated lipid metabolism are commonly found in Human Immunodeficiency Virus/Acquired Immunodeficiency Syndrome (HIV/AIDS) patients using anti-retroviral therapy (HAART). Thus, the aim of this study was to identify the effect of a bioactive food compound (BFC) containing functional foods on individuals with HIV undergoing HAART. Particularly, this study aims to verify the clinical outcome in the change of the lipid profile due to the use of this compound. This study includes 115 individuals with HIV on HAART...

Biologic therapies are injectable immunomodulatory agents directed against specific immune cell or chemical targets. They have transformed the lives of HIV-uninfected individuals with severe inflammatory conditions including psoriasis, rheumatoid arthritis, and ulcerative colitis. The perceived increased infection risk associated with these agents means that HIV-infected individuals have not been included in randomised control trials of these drugs. The literature for use of biologic therapies in HIV-infected populations is limited to case reports and case series...

Gene therapy protocols require robust and long-term gene expression. For two decades, retrovirus family vectors have offered several attractive properties as stable gene-delivery vehicles. These vectors represent a technology with widespread use in basic biology and translational studies that require persistent gene expression for treatment of several monogenic diseases. Immunogenicity and insertional mutagenesis represent the main obstacles to a wider clinical use of these vectors. Efficient and safe non-viral vectors are emerging as a promising alternative and facilitate clinical gene therapy studies...

Retroviruses belong to the family Retroviridae and are ribonucleoprotein (RNP) particles that contain a dimeric RNA genome. Retroviral particle assembly is a complex process, and how the virus is able to recognize and specifically capture the genomic RNA (gRNA) among millions of other cellular and spliced retroviral RNAs has been the subject of extensive investigation over the last two decades. The specificity towards RNA packaging requires higher order interactions of the retroviral gRNA with the structural Gag proteins...

We herein describe a case of progressive human immunodeficiency virus (HIV)-associated cholangiopathy despite normalization of laboratory parameters, which had indicated liver dysfunction, after the initiation of combined anti-retroviral therapy (cART). HIV-associated cholangiopathy remains important as a differential diagnosis of bile duct disorders, although it is considered to be a rare disease in the era of cART. Magnetic resonance cholangiopancreatography could thus be a powerful tool for the diagnosis and follow-up of this disease...

HIV cure is now the focus of intense research after Timothy Ray Brown (the Berlin patient) set the precedent of being the first and only person cured. A major barrier to achieving this goal on a meaningful scale is an elimination of the latent reservoir, which is thought to comprise CD4-positive cells that harbor integrated, replication-competent HIV provirus. These cells do not express viral proteins, are indistinguishable from uninfected CD4 cells, and are thought to be responsible for HIV viral rebound-that occurs within weeks of combination anti retroviral therapy (cART) interruption...

OBJECTIVE: Cortical sources of electroencephalographic (EEG) rhythms were investigated in two sub-populations of naïve HIV subjects, grouped based on clinical criteria to receive different combination anti-retroviral therapies (cARTs). These EEG sources were hypothesized to reflect beneficial effects of both regimes. METHODS: Eyes-closed resting state EEG data were collected in 19 (Group A) and 39 (Group B) naïve HIV subjects at baseline (i.e. pre-treatment; T0) and after 5months of cART (T5)...

Adherence to combination antiretroviral therapy (cART) is generally high in most resource-limited settings. However, sub-optimal adherence occurs in a sizable proportion of patients, and is independently predictive of detectable viremia. We investigated sub-optimal adherence according to self-report, clinician-recorded, and pharmacy-refill assessment methods, and their associated factors among HIV-infected adults receiving cART in Addis Ababa, Ethiopia. Eight-hundred seventy patients who initiated cART between May 2009 and April 2012 were randomly selected, and 664 patients who were alive, had remained in clinical care and were receiving cART for at least six-months were included...

Previous work by our group showed that transferring bone marrow cells transduced with a self-antigen induced immune tolerance and ameliorated experimental autoimmune encephalomyelitis (EAE), a model of multiple sclerosis (MS). We also found that following retroviral transduction of murine bone marrow (BM) cells, the majority of cells generated and transduced were myeloid-derived suppressor cells (MDSCs). Here, we aimed to determine whether purified antigen-expressing MDSCs have similar therapeutic effects than those of unfractionated BM, and to investigate their potential mechanisms...

Approximately 40% to 80% of patients receiving pertuzumab-directed therapy for human epidermal growth factor receptor 2 (HER2)-positive breast cancer will develop chemotherapy-induced diarrhea (CID). Loperamide and octreotide are frequently used to treat CID after diarrhea occurs, but neither is used prophylactically or targets the underlying mechanism. Previous studies suggest blocking epidermal growth factor receptor may cause excess chloride secretion, resulting in diarrhea. Crofelemer is derived from the red latex of the Croton lechleri tree, blocks gastrointestinal cystic fibrosis transmembrane regulator and calcium-activated chloride channels, and is U...

Clinical data accumulated over the past two decades attests to a significant decline in bone mineral density (BMD) in patients infected by HIV, which does not remit but may actually intensify with anti-retroviral therapy (ART). Long generally perceived as an aberration without clinical consequences in relatively young HIV-infected cohorts, recent studies have documented marked increases in fracture incidence in HIV-infected men and women over a wide age continuum. Fractures are associated with chronic pain, crippling morbidity, and increased mortality, undermining the gains in quality of life achieved though ART...
