OBJECTIVES: The aim of this study is to evaluate the salivary flow rate and gustatory changes in HIV-positive patients on highly active anti-retroviral therapy (HAART) and without HAART. We also correlated CD4 count and salivary flow rate and gustatory function in both groups. METHODS: Sample size for each group was thirty. After obtaining informed consent, we measured salivary flow rate using Schimer's method and gustatory function using four tastants (sweet, sour, bitter, and salty) of different concentrations...

Anaplastic thyroid cancer (ATC) is the most aggressive malignancy of the thyroid, during which undifferentiated tumors arise from the thyroid follicular epithelium. ATC has a very poor prognosis due to its aggressive behavior and poor response to conventional therapies. Gene-directed enzyme/prodrug therapy using genetically engineered mesenchymal stromal cells (MSC) is a promising therapeutic strategy. The doxycycline (DOX)-controlled Tet inducible system is the most widely utilized regulatory system and could be a useful tool for therapeutic gene-based therapies...

Chimeric antigen receptors (CARs) have been used to redirect the specificity of autologous T-cells against leukemia and lymphoma with promising clinical results.(1-3) Extending this approach to allogeneic T-cells is problematic as they carry a significant risk of graft-versus-host disease (GVHD). Natural killer (NK) cells are highly cytotoxic effectors, killing their targets in a non-antigen specific manner without causing GVHD. Cord blood (CB) offers an attractive, allogeneic, off-the-self source of NK cells for immunotherapy...

INTRODUCTION: The risk of perinatal HIV infection can be dramatically reduced through maternal antiretroviral therapy (ART) and infant antiretroviral (ARV) postnatal prophylaxis. The 2013 WHO guidelines recommended four to six weeks of nevirapine or zidovudine as post-natal prophylaxis, with possible extension to 12 weeks for high-risk breastfed infants. A systematic review was undertaken to determine if there is evidence for the WHO to recommend enhanced or extended prophylaxis for high-risk infants...

Until recently hematopoietic stem cell transplantation was the only curative option for Wiskott-Aldrich syndrome (WAS). The first attempts at gene therapy for WAS using a ϒ-retroviral vector improved immunological parameters substantially but were complicated by acute leukemia as a result of insertional mutagenesis in a high proportion of patients. More recently treatment of children with a state-of-the-art self-inactivating lentiviral vector (LV-w1.6 WASp) has resulted in significant clinical benefit without inducing selection of clones harbouring integrations near oncogenes...

The pathogenesis of Rb1 gene inactivation indicates that gene therapy could be a promising treatment for retinoblastoma. An appropriate gene transfer system is the basis for successful gene therapy; however, little attention has been given to an effective gene transfer system for retinoblastoma therapy in previous studies. This study was designed to provide an optimized transgene system for WERI‑Rb1 cells (W-RBCs). Green fluorescent protein (GFP) was adopted as a reporter. Four classic viral vectors based on retroviruses, recombinant adeno-associated viruses (rAAV2, rAAV2/1), lentiviruses (LVs) and a novel non-viral vector X-treme HP reagent were adopted for W-RBC gene transfection...

Antimalarial therapy during pregnancy poses important safety concerns due to potential teratogenicity and maternal physiological and biochemical changes during gestation. Piperaquine (PQ) has gained interest for use in pregnancy in response to increasing resistance towards sulfadoxine-pyrimethamine in sub-Saharan Africa. Co-infection with HIV is common in many developing countries, however, little is known about the impact of anti-retroviral (ARV) mediated drug-drug interaction (DDI) on PQ pharmacokinetics during pregnancy...

Cancer stem cells (CSCs) are capable of reconstructing cancer tissues, are involved in both recurrence and metastasis, and contribute to therapeutic resistance. Therefore, elucidating the molecular mechanism in CSCs is important to successfully treat unresectable cancers. Previously we observed that colon cancer stem-like cells can be induced from human colon cancer cell lines by retrovirally introducing OCT3/4, SOX2 and KLF4, and we have designated such cells as induced cancer stem cells (iCSCs). In the current study, we used iCSCs to evaluate the molecular mechanism of colon CSCs and developed new methods to control them...

BACKGROUND: Individuals with HIV have a high prevalence of physical and psychological symptoms throughout their disease course. Despite the clinical and public health implications of unresolved pain and symptoms, little is known about the effect of anti-retroviral therapy (ART) on these outcomes. This study aimed to assess the impact on symptom burden for the year after ART initiation in individuals with a CD4 count <200 cells/uL in Uganda. METHODS: HIV-infected, ART-naıve adults referred from voluntary testing and counseling services in rural Uganda for enrollment into a randomized controlled trial to test fluconazole as primary prophylaxis against cryptococcal disease were invited to complete the Memorial Symptom Assessment Scale-Short Form (MSAS-SF) prior to commencing ART and at two subsequent follow up visits...

The major challenges to clinical application of zidovudine are its moderate aqueous solubility and relative short half-life and serious side effects due to frequent administrations. We investigated the preparation of zidovudine-loaded nanoparticles based on lipids which were further modified with the polymer gelatin. Formulation and stability of the modified nanoparticles were analysed from the physico-chemical characterizations. The interactions of nanoparticles with blood components were tested by haemolysis and aggregation studies...

BACKGROUND: There is limited evidence on how health care inputs are distributed from the sub-national level down to health facilities and their potential influence on promoting health equity. To address this gap, this paper assesses equity in the distribution of health care inputs across public primary health facilities at the district level in Tanzania. METHODS: This is a quantitative assessment of equity in the distribution of health care inputs (staff, drugs, medical supplies and equipment) from district to facility level...

Excellent outcomes have been demonstrated among select HIV-positive kidney transplant (KT) recipients with well-controlled infection, but to date no national study has explored outcomes among HIV+ KT recipients by antiretroviral therapy (ART) regimen. IMS pharmacy fills (1/1/01 - 10/1/12) were linked with SRTR data. 332 recipients with pre- and post-transplant fills were characterized by ART at time of transplant as protease inhibitor (PI) or non-PI based ART (88 PI vs. 244 non-PI). Cox proportional hazards models were adjusted for recipient and donor characteristics...

The persistence of Human Immunodeficiency Virus (HIV) infection, even after lengthy and successful combined anti-retroviral therapy (cART), has precluded an effective cure. The anatomical locations in which and biological mechanisms through which the viral population is maintained remain unknown. Much research has focused nearly exclusively on circulating resting T-cells as the predominant source of persistent HIV, a strategy with limited success in developing an effective cure strategy. Here, we review research supporting the importance of tissues and other immune cells for HIV maintenance and expansion, including the central nervous system, lymph nodes, and macrophages...

BACKGROUND: Clients on anti-retroviral therapy (ART) are living longer and have risk of hypertension. Side effects of medicines and aging increase this risk. Hypertension prevalence among clients on ART in Kadoma City was estimated to be 30% in 2015. Of these, 61% had uncontrolled hypertension. This was high compared to 46% of hypertensives in the general population who had uncontrolled hypertension. We determined factors associated with uncontrolled hypertension among clients on ART...

BACKGROUND: Enhancer of zeste homolog 2 (EZH2), a stemness factor, plays roles in regulation of cell differentiation and embryonic development as well as cancer progression. Deregulation of EZH2 in cancers is correlated with tumor cell invasiveness, metastasis, and the patients' poor outcome. However, the mechanistic role of EZH2 in cancer is ambiguous. In this study, we aimed to inhibit the expression of EZH2 in a cancer cell line, and evaluate consequence changes in gene expression pattern...

OBJECTIVES: From the first time that human immunodeficiency virus (HIV) was discovered, till today both the quality of life and survival expectancy of HIV-infected patients have markedly improved. As the life expectancy of these patients increases due to the use of highly active anti-retroviral therapy (HAART) also increases the number of HIV-positive patient to be subjected to an operation. Different studies have examined the occurrence of complications in this particular group of patients and their possible susceptibility to infections or other complications that could lead to increased hospital stay, morbidity and mortality with controversial results...

Clinical application of lentiviral vector (LV)-based hematopoietic stem and progenitor cells (HSPC) gene therapy is rapidly becoming a reality. Nevertheless, LV-mediated signaling and its potential functional consequences on HSPC biology remain poorly understood. We unravel here a remarkably limited impact of LV on the HSPC transcriptional landscape. LV escaped innate immune sensing that instead led to robust IFN responses upon transduction with a gamma-retroviral vector. However, reverse-transcribed LV DNA did trigger p53 signaling, activated also by non-integrating Adeno-associated vector, ultimately leading to lower cell recovery ex vivo and engraftment in vivo These effects were more pronounced in the short-term repopulating cells while long-term HSC frequencies remained unaffected...

Since October 2015 up to September 2016, HIV diagnoses fell by 32% compared with October 2014-September 2015 among men who have sex with men (MSM) attending selected London sexual health clinics. This coincided with high HIV testing volumes and rapid initiation of treatment on diagnosis. The fall was most apparent in new HIV testers. Intensified testing of high-risk populations, combined with immediately received anti-retroviral therapy and a pre-exposure prophylaxis (PrEP) programme, may make elimination of HIV achievable...

Oesophageal ulcers are a rare cause of upper Gastrointestinal Bleeding (GIB). In patients with Acquired Immune Deficiency Syndrome (AIDS), oesophageal diseases including oesophageal ulcers are very common. Idiopathic Oesophageal Ulcers (IOU) comprises a subgroup of oesophageal ulcers with no identifiable cause. IOU mainly present as odynophagia, retrosternal chest pain, decreased oral intake, and weight loss. Upper GIB is a rare presentation. In the era of Highly Active Anti Retroviral Therapy (HAART), with improvement in CD4 count, this entity is almost forgotten...

Integration Site (IS) assays are a critical component of the study of retroviral integration sites and their biological significance. In recent retroviral gene therapy studies, IS assays, in combination with next-generation sequencing, have been used as a cell-tracking tool to characterize clonal stem cell populations sharing the same IS. For the accurate comparison of repopulating stem cell clones within and across different samples, the detection sensitivity, data reproducibility, and high-throughput capacity of the assay are among the most important assay qualities...
