    Full Text Available Human immunodeficiency virus (HIV has been documented to cause direct and indirect central nervous system dysfunction that can be observed as a progressive decline in neuropsychological functioning in a large proportion of persons with HIV and AIDS. Neuropsychological decline in individuals with HIV is characterized by cognitive and motor slowing, attentional deficits, executive dysfunction and memory impairment (characterized by intact recognition and deficits in learning and delayed recall. Dementia occurs in a relatively small proportion of HIV infected individuals, though milder NP deficits are observed in 30-50% of persons with advanced disease. Recent evidence suggests that drug users, especially stimulant users, are at risk for accelerated progression of their HIV disease, including a greater risk of neuropsychological dysfunction. Methamphetamine may potentiate HIV Tat protein mediated neurotoxicity giving rise to striatal proinflammatory cytokine stimulation and activation of redox-regulated transcription factors. Oxidative stress due to mitochondrial dysfunction is another candidate process underlying the synergistic effects of stimulant use and HIV. Damage to neurotransmitter systems including the dopaminergic, serotonergic and glutamatergic systems which are affected by both stimulant use and HIV is an alternate explanation. Methamphetamine has also been shown to impede the effectiveness of HAART, which could then in turn allow for more rapid HIV disease progression. A greater prevalence of psychiatric disorders, particularly mood, anxiety and substance use disorders are also observed in HIV positive samples relative to the general population. The changing nature of the HIV pandemic is an ongoing challenge to investigators and clinicians working in this field. Emerging issues requiring additional attention are study of the interactive effects of normal aging and HIV on neurocognition as well as study of the effects of co-infection

    Full Text Available We wanted to determine whether methamphetamine use affects a subset of plasma proteins in HIV-infected persons. Plasma samples from two visits were identified for subjects from four groups: HIV+, ongoing, persistent METH use; HIV+, short-term METH abstinent; HIV+, long term METH abstinence; HIV negative, no history of METH use. Among 390 proteins identified, 28 showed significant changes in expression in the HIV+/persistent METH+ group over the two visits, which were not attributable to HIV itself. These proteins were involved in complement, coagulation pathways and oxidative stress. Continuous METH use is an unstable condition, altering levels of a number of plasma proteins.

    Full Text Available The present study reports the prevalence of HIV infection among the drug addicts undergoing counselling and treatment in a drug deaddiction centre located in Bhubaneswar, during July 1996 to August 1997. All subjects were males. The coded serum samples were tested by ELISA and rapid spot test for the detection of HIV antibodies. The positive samples were finally confirmed by the line immunoassay for HIV infection. A high prevalence of 7% HIV infection was noticed among the drug addicts (n=100. Oral drug abusers and IDUs were positive for HIV-1 infection in 5.26% and 21.74% cases respectively. The present study reveals a high prevalence of HIV infection among the drug addicts for the first time from Orissa which needs a careful monitoring and surveillance.

    Illicit drug users sustain the epidemics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), hepatitis C (HCV), and sexually transmitted infections (STIs). Substance abuse treatment programs present a major intervention point in stemming these epidemics. As a part of the "Infections and Substance Abuse" study, established by the National Drug Abuse Treatment Clinical Trials Network, sponsored by National Institute on Drug Abuse, three surveys were developed; for treatment program administrators, for clinicians, and for state and District of Columbia health and substance abuse department administrators, capturing service availability, government mandates, funding, and other key elements related to the three infection groups. Treatment programs varied in corporate structure, source of revenue, patient census, and medical and non-medical staffing; medical services, counseling services, and staff education targeted HIV/AIDS more often than HCV or STIs. The results from this study have the potential to generate hypotheses for further health services research to inform public policy. PMID:16716846

    Background Following the increased human immunodeficiency virus (HIV) notification (infection) rates via sexual transmission and increased abuse of new synthetic drugs instead of heroin in China,a study on HIV infections and risk factors among synthetic drugs and heroin users in Beijing was conducted to provide a cue for further development of targets and strategies of HIV/AIDS control and prevention for different drug populations.Methods A total of 428 subjects including 224 heroin users and 204 new synthetic drug users was recruited from communities in Beijing by convenience sampling.A x2 test was used to compare HIV and syphilis infections between the two subpopulations.Logistic regression models were used to evaluate factors related to HIV,syphilis infections and abuse of synthetic drugs.Results Unbalanced distributions of demographics were detected between the two subpopulations.Compared with heroin users,most users of synthetic drugs were migrants,single and of younger age (age ≤30 years).Ten HIV infections and twenty-four syphilis infections were confirmed among 428 subjects.No significant difference in HIV infection was found between the two subpopulations (crude odds ratio (OR) =0.46,95% confidence interval (CI):0.07-15.80 and adjusted odds ratio (AOR) =1.26,95% CI:0.09-18.28) while four times as many syphilis infections were identified among users of synthetics drugs (AOR=3.92,95% CI:1.06-14.56).HIV and syphilis infections appeared to work synergistically.The migrants who were of Han ethnicity,single and who had stayed in Beijing for more than six months were more likely to abuse synthetics drugs.Conclusions The new synthetic drug users and heroin users are different subpopulations.We optimistically speculate that HIV has not yet been introduced into the former in Beijing,but considering higher syphilis infections in synthetic drug users and the role of syphilis in HIV infection,synthetic drug users,as a possible and important driver of the HIV

    To study the prevalence of oral manifestations, we examined 217 patients infected with the human immunodeficiency virus (HIV). Most of our patients were intravenous drug abusers (IVDAs) (65%). Other risk categories were represented by IVDAs who were also male homosexuals or bisexuals (11%), male homosexuals and bisexuals (16%), sexual partners of HIV-infected patients (5%), and hemophilic persons and recipients of blood transfusions (3%). Forty-six patients were women and 171 were men, with a median age of 27 years (range, 11 to 65 years). At the time of first examination, 38% of patients had asymptomatic HIV infection, 36% had lymphadenopathy syndrome, 17% had AIDS-related complex, and 9% had AIDS. Oral manifestations were observed in 89 (41%) patients. Of these, 15 had asymptomatic infection, 23 had lymphadenopathy syndrome, 27 had AIDS-related complex, and 24 had AIDS. Increasing severity of disease was significantly associated with higher prevalence of oral lesions (p less than or equal to 0.0001). Candidiasis was the most common oral lesion, followed by hairy leukoplakia. Kaposi's sarcoma, melanotic macules, herpes labialis, condyloma acuminatum, perioral molluscum contagiosum, and bacterial glossitis due to Escherichia coli infection were found in a small number of patients. Results of culture for fungi, available for 203 patients, revealed that 51% of patients with positive Candida cultures had clinical evidence of candidiasis. Our study demonstrates that oral lesions are also important signs of HIV infection among IVDAs. Early diagnosis of these manifestations is becoming increasingly significant in the practice of dentistry. PMID:2304743

    1995-02-01

    Both alcohol and human immunodeficiency virus (HIV) infection have been shown to produce central nervous system (CNS) morbidity in frontal brain regions. The degree to which the CNS morbidity in HIV infection, as it affects frontal cortex function, may be preferentially increased by alcohol abuse was examined using the auditory P3A evoked potential. The P3A indexes an orienting response, maximal over frontal cortex that occurs when novel nontarget stimuli are presented in the midst of a target detection paradigm. Four groups of subjects were compared: HIV+ alcohol abusers, HIV+ light/nondrinkers, HIV- alcohol abusers, and HIV- light/nondrinkers. The alcohol abuser and light/nondrinker HIV+ groups were matched on percent CD4 lymphocytes, insuring that the results reflected specific CNS effects and were not a result of differences between the groups in the degree of systemic immune suppression. Alcohol abuse and HIV infection had at least additive effects on P3A latency, consistent with alcohol abuse worsening the effect of HIV disease on frontal cortex function. Post-hoc analyses suggested that concomitant alcohol abuse results in the effects of HIV infection on P3A latency becoming manifest earlier in the HIV disease process. PMID:7727627

    Full Text Available Objective: To evaluate psychiatric comorbidities in outpatients receiving care for HIV and Chagas disease at Instituto de Pesquisa Clínica Evandro Chagas (IPEC, Fundação Oswaldo Cruz (Fiocruz, Rio de Janeiro, Brazil. Methods: Cross-sectional study with a consecutive sample of 125 patients referred to an outpatient psychiatric clinic from February to December 2010. The Mini International Neuropsychiatric Interview (MINI was used. Factors associated with more frequent mental disorders were estimated by odds ratios (OR with 95% confidence intervals (95%CI by multiple logistic regression. Results: Seventy-six (60.8% patients with HIV, 40 (32% patients with Chagas disease, and nine (7.2% patients with human T-lymphotropic virus were interviewed. The majority were women (64%, with up to 8 years of formal education (56%, and unemployed (81.6%. The median age was 49 years. Suicide risk (n=71 (56%, agoraphobia (n=65 (52%, major depressive episode (n=56 (44.8%, and alcohol/drug abuse (n=43 (34.4% predominated, the latter being directly associated with lower family income (OR = 2.64; 95%CI 1.03-6.75 and HIV infection (OR = 5.24; 95%CI 1.56-17.61. Suicide risk was associated with non-white skin color (OR = 2.21; 95%CI 1.03-4.75, unemployment (OR = 2.72; 95%CI 1.01-7.34, and diagnosis of major depression (OR = 3.34; 95%CI 1.54-7.44. Conclusion: Measures targeting adverse socioeconomic conditions and psychiatric and psychological monitoring and care should be encouraged in this population, considering the association with abuse of alcohol/other psychoactive drugs and suicide risk.

    The aim of this study was to investigate the influence of opiate abuse on the expression of Toll-like receptor 9 (TLR9) in the peripheral blood mononuclear cells (PBMCs) of HIV-1-infected patients and to elucidate possible mechanisms involved in the enhancement of HIV-1 replication by opiate abuse. A total of 200 participants were enrolled in the study by random selection from methadone treatment centers and voluntary HIV counseling and testing centers in the cities of Nanning, Liuzhou, and Qinzhou. These participants included 50 HIV-positive opiate abusers (Opiates HIV(+) group), 50 HIV-negative opiate abusers (Opiates HIV(-) group), 50 HIV-positive subjects who were not opiate abusers (Non-opiates HIV (+) group), and 50 HIV-negative subjects who were not opiate abusers (Control group). PBMCs were isolated from the peripheral blood samples from the subjects and the expression levels of TLR9 mRNA and protein were determined by q-PCR and western blot respectively. There was no significant difference among the four groups in age, gender, nationality, domicile, marital status, educational background or duration of drug abuse (P > 0.05). The median viral loads of the Opiates HIV(+) were significantly higher than those of the Non-Opiates HIV(+) groups (4.450 x 10(3) and 3.977 x 10(3) copies/mL respectively, P Opiates HIV(+), Non-Opiates HIV(+), Opiates HIV(-) and Control groups were (2.13 +/- 1.59) x 10(-3), (3.66 +/- 2.22) x 10(-3), (1.96 +/- 1.42) x 10(-3) and (7.66 +/- 4.87) x 10(-3), respectively. The expression of TLR9 mRNA was significantly lower in both HIV-1-infected and -uninfected groups of opiate abusers compared with groups of non-abusers (P Opiates HIV(+) group and the Opiates HIV(-) group (P > 0.05). However, in the non-opiate groups, the expression levels of TLR9 mRNA in the HIV(+) group were significantly lower than that of the control group (POpiates HIV(+), Non-Opiates HIV(+), and Opiates HIV(-) groups compared to the control group.

    2006-01-01

    Full Text Available Although endocrine abnormalities have been reported in HIV-1 infection, the role of risk factors is not understood. Injecting drug use (IDU is an important risk factor for contracting HIV-infection and studies suggest that substance use may also be associated with endocrine dysfunction. In order to investigate hypothalamic pituitary adrenal (HPA axis activity in this population, this study investigated cortisol response to the cold pressor challenge in IDUs with and without HIV infection. After controlling for the effects of gender, duration of marijuana use and time since the last use of heroin, the findings show that the pattern of cortisol response depended upon HIV serostatus. Cortisol levels peaked later in HIV+ IDUs and recovered at a slower rate than HIV negative IDUs. These findings support our hypothesis that dysregulation in HPA axis activity occurs in HIV infected IDUs.

    To determine whether nitrogen monoxide (nitric oxide; NO) synthase (NOS) and NADPH diaphorase (NDP) co-containing cerebrocortical neurons (NOSN) neurons are affected in patients infected with human immunodeficiency virus type 1 (HIV-1) with and without associated intake of drugs of abuse, we examined the temporal neocortex of 24 individuals: 12 HIV-1 positive (including 3 drug users, 9 non-drug users) and 12 HIV-1 negative (including 6 drug users, and 6 non-drug users). Histochemical labeling for NDP-an enzymatic domain co-expressed in the NOS enzyme-was employed to visualize NOSN. Drug abuse and HIV-1 infection cause independently an increase in NOSN density, but combined they result in up to a 38-fold increase in NOSN density, suggesting that the combination of these factors induces NOS expression powerfully in neurons that normally do not synthesize NDP/NOS. This is associated with an increase in the proportion of NOSN displaying dystrophic changes, indicating that NOSN undergo massive degeneration in association with NOS synthesis induction. The increase in density of NOSN in HIV-1 infected drug abusers may be among the important sources of NO mediating cerebrocortical dysfunction, and the degeneration of NOS-containing local circuit neurons in patients with HIV-1 infection or drug abuse may underlie in part their neuropsychiatric manifestations.

    Benson, J D

    1995-04-01

    Research has been conducted on the effects of childhood abuse that may lead to HIV risk-taking behaviors in adolescence and adulthood. There is evidence of a higher incidence of childhood abuse among HIV-infected individuals and those at highest risk, but not enough evidence to confirm childhood abuse as a root cause of risk-taking. Research is beginning to show important connections between psychological trauma and risk, and to suggest therapeutic approaches. The trauma of childhood sexual abuse is retained by the victims, which can cause dissociative defenses and damaging feelings of self-efficacy which may affect safer sex practices. To identify sexual abuse as an issue in therapy, it is advised that counselors develop client histories regarding relationships, sexual expression and identity, substance use, suicidality, and other recurring self-destructive patterns of thought and behavior. The treatment goal is to assist the patient in understanding how abuse has affected feelings, thoughts, and relationship styles, and to recognize patterns that lead directly to HIV-related risk or that set the stage for risky activities. The critical aspect of treatment is to accurately assess the patient's coping skills when determining the course of treatment. ¿¿¿¿¿¿¿ PMID:11362459

    2006-01-01

    Full Text Available In the last decade, it has become increasingly apparent that neuropsychological deficits and impairments are associated with HIV infection. Given that antiretroviral therapies have extended the life expectancy of HIV-infected persons, it becomes critical to focus on the physical and mental health of these patients. Understanding the neuropsychology of HIV disease can provide insight into improving mental health, functional capacity and overall quality of life for persons living with HIV/AIDS. Furthermore, clinicians may be better able to assist patients to manage their symptoms, thereby increasing the number of patients who are able to successfully maintain difficult treatment schedules. In addition, it is equally important to understand the potentially exacerbating effects of various factors. One such factor is substance abuse, which has been associated with various neuropsychological impairments, irrespective of the substance of abuse. Therefore, a more complete understanding of the effects of substance abuse on the progression of impaired cognitive processes and functioning can allow for an enhanced evaluation and management of those patients who live with HIV disease and who suffer from substance abuse disorders. As such, the present paper provides an overview of the neuropsychology of HIV and substance abuse, as well as of the available research that has examined the potential interaction effects between HIV disease and substance abuse. The implications of the findings as well as directions for future research are discussed.

  10. Drugs of abuse, dopamine, and HIV-associated neurocognitive disorders/HIV-associated dementia.

    2011-08-01

    Although the incidence of HIV-associated dementia (HAD) has declined, HIV-associated neurocognitive disorders (HAND) remain a significant health problem despite use of highly active antiretroviral therapy. In addition, the incidence and/or severity of HAND/HAD are increased with concomitant use of drugs of abuse, such as cocaine, marijuana, and methamphetamine. Furthermore, exposure to most drugs of abuse increases brain levels of dopamine, which has been implicated in the pathogenesis of HIV. This review evaluates the potential role of dopamine in the potentiation of HAND/HAD by drugs of abuse. In the brain, multiplication of HIV in infected macrophages/microglia could result in the release of HIV proteins such as gp120 and Tat, which can bind to and impair dopamine transporter (DAT) functions, leading to elevated levels of dopamine in the dopaminergic synapses in the early asymptomatic stage of HIV infection. Exposure of HIV-infected patients to drugs of abuse, especially cocaine and methamphetamine, can further increase synaptic levels of dopamine via binding to and subsequently impairing the function of DAT. This accumulated synaptic dopamine can diffuse out and activate adjacent microglia through binding to dopamine receptors. The activation of microglia may result in increased HIV replication as well as increased production of inflammatory mediators such as tumor necrosis factor (TNF)-alpha and chemokines. Increased HIV replication can lead to increased brain viral load and increased shedding of HIV proteins, gp120 and Tat. These proteins, as well as TNF-alpha, can induce cell death of adjacent dopaminergic neurons via apoptosis. Autoxidation and metabolism of accumulated synaptic dopamine can lead to generation of reactive oxygen species (hydrogen peroxide), quinones, and semiquinones, which can also induce apoptosis of neurons. Increased cell death of dopaminergic neurons can eventually lead to dopamine deficit that may exacerbate the severity and

    2012-01-01

    Full Text Available HIV epidemic continues to be a severe public health problem and concern within USA and across the globe with about 33 million people infected with HIV. The frequency of drug abuse among HIV infected patients is rapidly increasing and is another major issue since injection drug users are at a greater risk of developing HIV associated neurocognitive dysfunctions compared to non-drug users infected with HIV. Brain is a major target for many of the recreational drugs and HIV. Evidences suggest that opiate drug abuse is a risk factor in HIV infection, neural dysfunction and progression to AIDS. The information available on the role of morphine as a cofactor in the neuropathogenesis of HIV is scanty. This review summarizes the results that help in understanding the role of morphine use in HIV infection and neural dysfunction. Studies show that morphine enhances HIV-1 infection by suppressing IL-8, downregulating chemokines with reciprocal upregulation of HIV coreceptors. Morphine also activates MAPK signaling and downregulates cAMP response element-binding protein (CREB. Better understanding on the role of morphine in HIV infection and mechanisms through which morphine mediates its effects may help in devising novel therapeutic strategies against HIV-1 infection in opiate using HIV-infected population.

    Arn J Schilder

    Full Text Available INTRODUCTION: The association between childhood sexual abuse and HIV risk among men who have sex with men (MSM is well established. However, no studies have examined the potential impact of other forms of childhood maltreatment on HIV incidence in this population. METHODS: We explored the impact of child physical abuse (CPA on HIV seroconversion in a cohort of gay/bisexual men aged 15 to 30 in Vancouver, Canada. Cox proportional hazard models were used, controlling for confounders. RESULTS: Among 287 participants, 211 (73.5% reported experiencing CPA before the age of 17, and 42 (14.6% reporting URAI in the past year. After a median of 6.6 years follow-up, 16 (5.8% participants HIV-seroconverted. In multivariate analysis, CPA was significantly associated with HIV seroconversion (adjusted hazard ratio [AHR] = 4.89, 95% confidence interval (CI: 1.65-14.48, after controlling for potential confounders. CONCLUSION: Our study uncovered a link between childhood physical violence and HIV incidence. Results highlight an urgent need for screening of young gay and bisexual men for histories of violence, and social and structural supports to prevent HIV transmission in this population.

    We studied HLA antigen distribution of 50 heterosexual partners of HIV+ drug abusers with more than 1 year of sexual exposure to HIV, 36 children born to seropositive mothers and 61 haemophiliac patients exposed to presumably infectious clotting factor concentrates. B52 and B44 antigens were associated with HIV resistance while B51 was associated with HIV susceptibility. Forty-nine HIV+ drug abusers, spouses of heterosexual partners studied and 25 HIV+ mothers of the children were also typed. DR11 phenotype was associated with infectiousness of HIV+ subjects. Our data suggest that the HLA region controls susceptibility to infection with HIV and infectiousness of HIV+ subjects in different risk groups. PMID:1733633

    Full Text Available An increased colonization of Malassezia furfur organism has been reported in patients with HIV infection. Pityriasis versicolour and pityrosporum folliculitis arise from overgrowth of M. furfur. It is also thought to have a significant role in the pathogenesis of seborrhoeic dermatitis and is one of the earliest clinical markers of HIV infection. The present study was to note the occurrence and significance of these infections in HIV infected patients. The present study was to note the occurrence and significance of these infections in HIV infected patients. The occurrence of pityrosporum infection was 13.5% (25 cases amongst 185 HIV serpositive patients in HIV infected cases in our study. Mean age of the affected patients was 31.7 years and male to female ratio was 1.5:1. The main mode of acquisition of HIV infection was heterosexual (19 cases. Tinea versicolour was seen in 10 (40% cases, seborrhoeic was found to be more explosive in onset and involving extensive areas with severe inflammation. Extensive tinea versicolour and seborrhoeic dermatitis were seen in three cases with pityrosporum infections. Nine of the pityrosporum infections were observed in HIV group IV, which is equivalent of AIDS. To conclude, seborrhoeic dermatitis in patients with HIV/AIDS may have some unique features and may be used as a clinical marker of AIDS.

  3. MUCOCILIARY DYSFUNCTION IN HIV AND SMOKED SUBSTANCE ABUSE

    Directory of Open Access Journals (Sweden)

    2015-10-01

    Full Text Available Impaired mucociliary clearance (MCC is a hallmark of acquired chronic airway diseases like chronic bronchitis associated with chronic obstructive pulmonary disease (COPD and asthma. This manifests as microbial colonization of the lung consequently leading to recurrent respiratory infections. People living with HIV demonstrate increased incidence of these chronic airway diseases. Bacterial pneumonia continues to be an important comorbidity in people living with HIV even though anti-retroviral therapy has succeeded in restoring CD4+ cell counts. People living with HIV demonstrate increased microbial colonization of the lower airways. The microbial flora is similar to that observed in diseases like cystic fibrosis and COPD suggesting that mucociliary dysfunction could be a contributing factor to the increased incidence of chronic airway diseases in people living with HIV. The three principal components of the MCC apparatus are, a mucus layer, ciliary beating and a periciliary airway surface liquid (ASL layer that facilitates ciliary beating. Cystic fibrosis transmembrane conductance regulator (CFTR plays a pivotal role in regulating the periciliary airway surface liquid. HIV proteins can suppress all the components of the MCC apparatus by increasing mucus secretion and suppressing CFTR function. This can decrease ASL height leading to suppressed ciliary beating. The effects of HIV on MCC are exacerbated when combined with other aggravating factors like smoking or inhaled substance abuse, which by themselves can suppress one or more components of the MCC system. This review discusses the pathophysiological mechanisms that lead to MCC suppression in people living with HIV who also smoke tobacco or abuse illicit drugs.

    2013-01-01

    Partner abuse (PA) is a highly prevalent and devastating social phenomenon, extracting an economic toll of more than $8 billion in the United States due to lost productivity alone. Many of the risk factors for PA increase vulnerability to acquiring HIV as well, yet little research has explored these overlapping epidemics. In this systematic review, we examine the frequency of PA victimization from male partners among persons living with HIV (PLWH)—both men who have sex with men (MSM) and women. We located 31 manuscripts reporting data from 24 unique samples, indicating a high lifetime frequency (but large range) of estimates for women/MSM, respectively, for physical (26–62%/15–39%), sexual (22–44%/8–33%), and psychological abuse (55%/22–73%). Data indicate strong and consistent associations of PA with poor mental health, engagement in health risk behaviors, and non-adherence to HIV medication for both groups. We discuss implications for clinical practice as well as future research directions. PMID:24070646

    The abuse of intravenous drugs, such as heroin, has become a major public health concern due to the increased risk of HIV-1 infection. Opioids such as heroin were originally identified and subsequently abused for their analgesic effects. However, many investigations have found additional effects of opioids, including regulation of the immune system. As such, chronic opioid abuse has been shown to promote HIV-1 pathogenesis and facilitate HIV-1-associated neurocognitive dysfunction. Clinical o...

    Full Text Available Nancy Nguyen1, Mark Holodniy21University of the Pacific School of Pharmacy and Health Sciences, Stockton, CA, USA; 2VA Palo Alto Health Care System, Palo Alto, CA, USAAbstract: In the US, an estimated 1 million people are infected with HIV, although one-third of this population are unaware of their diagnosis. While HIV infection is commonly thought to affect younger adults, there are an increasing number of patients over 50 years of age living with the condition. UNAIDS and WHO estimate that of the 40 million people living with HIV/AIDS in the world, approximately 2.8 million are 50 years and older. With the introduction of highly active antiretroviral therapy (HAART in the mid-1990s, survival following HIV diagnosis has risen dramatically and HIV infection has evolved from an acute disease process to being managed as a chronic medical condition. As treated HIV-infected patients live longer and the number of new HIV diagnoses in older patients rise, clinicians need to be aware of these trends and become familiar with the management of HIV infection in the older patient. This article is intended for the general clinician, including geriatricians, and will review epidemiologic data and HIV treatment as well as provide a discussion on medical management issues affecting the older HIV-infected patient.Keywords: HIV, epidemiology, treatment, aging, review

    Experience from two HIV-preventive projects among drug abusers in Oslo, Norway, shows that HIV-positive drug abusers carry on their drug abuse independent of visits to residential drug-free treatment or prison. HIV-positive former drug abusers show a tendency to relapse to drug abuse. In terms of HIV-prevention among drug abusers it is important to reduce injection of drugs among HIV-positive drug abusers. Thus, methadone maintenance programmes should be considered in HIV-prevention in Norway. PMID:2363170

    Full Text Available The purpose of this study was to assess the possible correlation between Brucella and HIV infections. Iran is a country where HIV infection is expanding and Brucellosis is prevalent. In the present study, 184 HIV infected patients were assigned and for all of them HIV infection was confirmed by western blot test. In order to identify the prevalence rate of Brucella infection and systemic brucellosis in these subjects, sera samples were obtained and Brucella specific serological tests were performed to reveal antibody titers. Detailed history was taken and physical examination was carried out for all of patients. 11 (6% subjects had high titers but only 3 of them were symptomatic. Most of these subjects were injection drug user (IDU men and one was a rural woman. Considering both prevalence rates of Brucella infection (3% and symptomatic brucellosis (0.1% in Iran, our HIV positive patients show higher rates of Brucella infection and systemic brucellosis. Preserved cellular immunity of participants and retention of granulocytes activity may explain this poor association; whereas other explanations such as immunological state difference and non-overlapping geographical distribution of the 2 pathogens have been mentioned by various authors.

    Full Text Available Context: The choice of antiretroviral therapy for HIV-2 differs from that for HIV-1, underscoring the importance of differentiating between the two. Aims: The current study was planned to find out the prevalence of HIV-2 infection at our center and to find out the utility of the current diagnostic algorithm in identifying the type of HIV infection. Setting and Design: Retrospective analysis in a tertiary care teaching institute over a period of three years. Materials and Methods: All patients diagnosed as HIV infected using NACO/WHO HIV testing strategy III were included in the study. They were classified as HIV-1 infected, HIV-2 infected and HIV-1 and HIV-2 co-infected based on their test results. For discordant samples, immunoblotting result from National Reference Laboratory was considered as final. Statistical Analysis Used: Comparison between HIV-1, HIV-2 and HIV-1+2 positive groups for age, gender, route of transmission was made using chi squared test. P value < 0.05 was considered as significant. Results: Of the total of 66,708 patients tested, 5,238 (7.9% were positive for HIV antibodies. 7.62%, 0.14%, 0.08% and 0.004% were HIV-1, HIV-2, HIV-1 and HIV-2 co-infected and HIV type indeterminate (HIV-1 Indeterminate, 2+ respectively. The current algorithm could not differentiate between the types of HIV infection (as HIV-1 or HIV-2 in 63 (1.2% cases. Conclusion: In areas like the Indian subcontinent, where epidemic of both HIV-1 and HIV-2 infections are ongoing, it is important to modify the current diagnostic algorithms to diagnose and confirm HIV-2 infections.

    2013-06-01

    Full Text Available Bromodomains are conserved protein modules of ~110 amino acids that bind acetylated lysine residues in histone and non-histone proteins. Bromodomains are present in many chromatin-associated transcriptional regulators and have been linked to diverse aspects of the HIV life cycle, including transcription and integration. Here, we review the role of bromodomain-containing proteins in HIV infection. We begin with a focus on acetylated viral factors, followed by a discussion of structural and biological studies defining the involvement of bromodomain proteins in the HIV life cycle. We end with an overview of promising new studies of bromodomain inhibitory compounds for the treatment of HIV latency.

    Full Text Available Abstract Objectives HIV-infected patients are at increased risk of developing mental health symptoms, which negatively influence the treatment of the HIV-infection. Mental health problems in HIV-infected patients may affect public health. Psychopathology, including depression and substance abuse, can increase hazardous sexual behaviour and, with it, the chance of spreading HIV. Therefore, it is important to develop an optimal treatment plan for HIV-infected patients with mental health problems. The majority of HIV-infected patients in the Netherlands (almost 60% are homosexual men. The main objectives of this study were to describe the clinical and demographic characteristics of patients with HIV who seek treatment for their mental health symptoms in the Netherlands. Secondly, we tested whether HIV infected and non-infected homosexual patients with a lifetime depressive disorder differed on several mental health symptoms. Methods We compared a cohort of 196 patients who visited the outpatient clinic for HIV and Mental Health with HIV-infected patients in the general population in Amsterdam (ATHENA-study and with non-HIV infected mental health patients (NESDA-study. DSM-IV diagnoses were determined, and several self-report questionnaires were used to assess mental health symptoms. Results Depressive disorders were the most commonly occurring diagnoses in the cohort and frequent drug use was common. HIV-infected homosexual men with a depressive disorder showed no difference in depressive symptoms or sleep disturbance, compared with non-infected depressive men. However, HIV-positive patients did express more symptoms like fear, anger and guilt. Although they showed significantly more suicidal ideation, suicide attempts were not more prevalent among HIV-infected patients. Finally, the HIV-infected depressive patients displayed a considerably higher level of drug use than the HIV-negative group. Conclusion Habitual drug use is a risk factor for

    Substance abuse is a major barrier in eradication of the HIV epidemic because it serves as a powerful cofactor for viral transmission, disease progression, and AIDS-related mortality. Cocaine, one of the commonly abused drugs among HIV-1 patients, has been suggested to accelerate HIV disease progression. However, the underlying mechanism remains largely unknown. Therefore, we tested whether cocaine augments HIV-1-associated CD4(+) T-cell decline, a predictor of HIV disease progression. We examined apoptosis of resting CD4(+) T cells from HIV-1-negative and HIV-1-positive donors in our study, because decline of uninfected cells plays a major role in HIV-1 disease progression. Treatment of resting CD4(+) T cells with cocaine (up to 100 μmol/L concentrations) did not induce apoptosis, but 200 to 1000 μmol/L cocaine induced apoptosis in a dose-dependent manner. Notably, treatment of CD4(+) T cells isolated from healthy donors with both HIV-1 virions and cocaine significantly increased apoptosis compared with the apoptosis induced by cocaine or virions alone. Most important, our biochemical data suggest that cocaine induces CD4(+) T-cell apoptosis by increasing intracellular reactive oxygen species levels and inducing mitochondrial depolarization. Collectively, our results provide evidence of a synergy between cocaine and HIV-1 on CD4(+) T-cell apoptosis that may, in part, explain the accelerated disease observed in HIV-1-infected drug abusers.

    Currently, there are around 150,000 HIV-infected patients in Spain. This number, together with the fact that this disease is now a chronic condition since the introduction of antiretroviral therapy, has generated an increasing demand on the clinical microbiology laboratories in our hospitals. This increase has occurred not only in the diagnosis and treatment of opportunistic diseases, but also in tests related to the diagnosis and therapeutic management of HIV infection. To meet this demand, the Sociedad de Enfermedades Infecciosas y Microbiología Clinica (Spanish Society of Infectious Diseases and Clinical Microbiology) has updated its standard Procedure for the microbiological diagnosis of HIV infection. The main advances related to serological diagnosis, plasma viral load, and detection of resistance to antiretroviral drugs are reviewed in this version of the Procedure.

    males to females. There are 37,306 people living with HIV (PLHIV) who are eligible for treatment, and 14,002 PLHIV were receiving antiretroviral treatment (ART) in 2011. The decreasing trend of heroin users who have been detected and arrested could be due to the introduction of medical treatments and harm reduction approaches for drug users, resulting in fewer drug users being arrested. However, we are unable to say with certainty why there has been an increase in heroin seizures in the country. There has been an increasing trend in both ATS users and seizures. A new trend of co-occurring opiate dependence and ATS underscores the need to develop and implement effective treatments for ATS, co-occurring opiate and ATS, and polysubstance abuse disorders. The low numbers of NSEP clients being tested for HIV underscores our caution in interpreting the decline of HIV infections among drug users and the importance of focusing on providing education, prevention, treatment, and outreach to those who are not in treatment.

    Substance abuse is a risk factor for HIV infection and progression to AIDS. Recent evidence establishes that cocaine use promotes brain perivascular macrophage infiltration and microglia activation. The lysosomal protease cathepsin B is increased in monocytes from patients with HIV dementia and its secretion induces 10-15% of neurotoxicity. Here we asked if cocaine potentiates cathepsin B secretion from HIV-infected monocyte-derived macrophages (MDM) and its effect in neuronal apoptosis. Samp...

    2007-02-01

    Full Text Available Avascular necrosis (AVN of the femoral head is an emerging complication in HIV infected patients. It has been suggested that the increased incidence of AVN in this population may be caused by an increased prevalence of predisposing factors for osteonecrosis, including protease inhibitors, hyperlipidemia, corticosteroid use, alcohol and intravenous drug abuse. The aim of this study was to assess the risk factors for avascular necrosis developing in the femoral head of HIV infected individuals. This study consisted of meta-analysis of the secondary data extracted from current literature. The selected articles allowed two study groups to be drawn up for comparison. Group 1 comprised 324 individuals infected by the HIV virus, who did not present femoral head AVN. Group 2 comprised 32 HIV positive patients, who presented femoral head AVN. The parameters used for analysis were as follows: age, gender, sexual preference, use of intravenous drugs, time of diagnosis, CD4+ cell count, use of antiretroviral agents and duration, serum cholesterol and serum triglycerides. The present study found a statistically significant association between hypertriglyceridemia, hypercholesterolemia, sexual preference and intravenous drug abuse. The authors concluded that femoral head osteonecrosis is associated with hyperlipidemia (hypercholesterolemia and hypertriglyceridemia and intravenous drug abuse. This study supports the hypothesis that protease inhibitors play a role in the development of osteonecrosis through a tendency to cause hyperlipidemia.

    HIV-1 infection is a global public health problem with more than 34 million people living with HIV infection. Although great strides have been made in treating this epidemic with therapeutic agents, the increase in patient life span has been coincident with an increase in the prevalence of HIV-associated neurocognitive disorders (HAND). HAND is thought to result from the neurotoxic effects of viral proteins that are shed from HIV-infected microglial cells. One of the primary neurotoxins responsible for this effect is the HIV-1 glycoprotein gp120. Exposure of neurons to gp120 has been demonstrated to cause apoptosis in neurons, as well as numerous indirect effects such as an increase in inflammatory cytokines, an increase in oxidative stress, and an increase in permeability of the blood-brain barrier. In many patients, the use of drugs of abuse (DOA) exacerbates the neurotoxic effects of gp120. Cocaine, methamphetamine and morphine are three DOAs that are commonly used by those infected with HIV-1. All three of these DOAs have been demonstrated to increase oxidative stress in the CNS as well as to increase permeability of the blood-brain barrier. Numerous model systems have demonstrated that these DOAs have the capability of exacerbating the neurotoxic effects of gp120. This review will summarize the neurotoxic effects of gp120, the deleterious effects of cocaine, methamphetamine and morphine on the CNS, and the combined effects of gp120 in the context of these drugs.

    Transgender women are overrepresented in the Caribbean HIV epidemic. The study objective was to examine correlates of HIV infection and HIV testing among transgender women in Jamaica. We implemented a cross-sectional survey with transgender women in Kingston and Ocho Rios, Jamaica. We conducted multivariable logistic regression to identify factors associated with HIV testing and HIV infection. Among 137 transgender women [mean age 24.0; standard deviation (SD) 5.5], three-quarters (n = 103, 75.7%) had received an HIV test. Of these, one-quarter (n = 26, 25.2%) were HIV positive. In multivariable analyses, HIV testing was associated with: perceived HIV risk [adjusted odds ratio (AOR) 2.42, confidence interval (CI) 1.36-4.28], depression (AOR 1.34, CI 1.01-1.77), forced sex (AOR 3.83, CI 1.42-10.35), physical abuse (AOR 4.11, CI 1.44-11.72), perceived transgender stigma (AOR 1.23, 1.06-1.42), having a healthcare provider (AOR 5.89, CI 1.46-23.77), and lower HIV-related stigma (AOR 0.96, CI 0.92-0.99), incarceration (AOR 0.28, CI 0.10-0.78), and drug use (AOR 0.74, CI 0.58-0.95). HIV infection was associated with the following: homelessness (AOR 5.94, CI 1.27-27.74), perceived HIV risk (AOR 1.67, CI 1.02-2.72), depression (AOR 1.39, CI 1.06-1.82), STI history (AOR 56.79, CI 5.12-630.33), perceived (AOR 1.26, CI 1.06-1.51) and enacted (AOR 1.16, CI 1.04-1.29) transgender stigma, forced sex (AOR 4.14, CI 1.49-11.51), physical abuse (AOR 3.75, CI 1.39-10.12), and lower self-rated health (AOR 0.55, CI 0.30-0.98) and social support (AOR 0.79, CI 0.64-0.97). Transgender women in Jamaica experience high HIV infection rates and suboptimal HIV testing. Combination HIV prevention approaches should address transgender women's social and structural vulnerabilities. PMID:27610463

  15. Heroin Inhibits HIV-Restriction miRNAs and Enhances HIV Infection of Macrophages

    2015-11-01

    Full Text Available Although opioids have been extensively studied for their impact on the immune system, limited information is available about the specific actions of opioids on intracellular antiviral innate immunity against HIV infection. Thus, we investigated whether heroin, one of the most abused drugs, inhibits the expression of intracellular HIV restriction microRNA (miRNA and facilitates HIV replication in macrophages. Heroin treatment of macrophages enhanced HIV replication, which was associated with the downregulation of several HIV restriction miRNAs. These heroin-mediated actions on the miRNAs and HIV could be antagonized by naltrexone, an opioid receptor antagonist. Furthermore, the in vitro negative impact of heroin on HIV-associated miRNAs was confirmed by the in vivo observation that heroin addicts had significantly lower levels of macrophage-derived HIV restriction miRNAs than those in the control subjects. These in vitro and in vivo findings indicate that heroin use compromises intracellular anti-HIV innate immunity, providing a favorable microenvironment for HIV survival in the target cells.

    The brain remains a major target for HIV infection and a site of potential complications for HIV-infected individuals. Emerging data presented at the 2016 Conference on Retroviruses and Opportunistic Infections suggest that during the early stages of infection, activated CD4+ cells may traffic the virus into the central nervous system (CNS). HIV is detectable in cells and tissues of the CNS in some individuals despite suppressive antiretroviral treatment. A potential source of cerebrospinal fluid HIV escape may be compartmentalized HIV replication within macrophage lineage cells. Virally infected cells can traffic out of the CNS and may have the potential to reseed the systemic compartment. Additional modifiers of HIV-associated neurocognitive disorder (HAND) were identified, including female sex and hepatic dysfunction. Large epidemiologic studies reported an elevated risk of stroke among HIV-infected individuals, related to traditional vascular risk factors, history of recreational drug use, and HIV measures (lower CD4+ cell nadir and higher viral load). Brain imaging may provide a noninvasive means for detecting early changes in the brain associated with HIV infection and may assist in prognosis of HAND. Some potential adjunctive therapies to standard antiretroviral therapy for HIV-infected individuals were considered. PMID:27398860

    Acute kidney injury (AKI) and chronic kidney disease (CKD) are more common in HIV-infected persons than in the general population. AKI is associated with poor health outcomes, including increased risk of heart failure, cardiovascular events, end-stage renal disease (ESRD), and mortality. The most common causes of AKI in HIV-infected persons are systemic infections and adverse drug effects. The prevalence of CKD is rising in the HIV-infected population and CKD is increasingly likely to be caused by comorbid conditions, such as diabetes and hypertension, that frequently cause CKD in the general population. Guidelines for CKD screening in HIV-infected patients are being revised. It is currently recommended that all patients be screened for creatinine-based estimates of glomerular filtration rate and for urine protein at the time of HIV diagnosis. Annual screening is recommended for high-risk patients. Hemodialysis, peritoneal dialysis, and kidney transplantation are all options for treating ESRD in HIV-infected patients. Hemodialysis and peritoneal dialysis offer similar survival in HIV-infected patients with ESRD. In selected patients with well-controlled HIV infection, kidney transplantation is associated with survival intermediate between that in the overall transplant population and that among transplant recipients older than 65 years. This article summarizes a presentation by Christina M. Wyatt, MD, at the IAS-USA continuing medical education program held in Chicago in May 2012, describing AKI and CKD using case illustrations.

    Substantial epidemiological studies suggest that not only, being one of the reasons for the transmission of the human immunodeficiency virus (HIV), but drug abuse also serves its role in determining the disease progression and severity among the HIV infected population. This article focuses on the drug cocaine, and its role in facilitating entry of HIV into the CNS and mechanisms of development of neurologic complications in infected individuals. Cocaine is a powerfully addictive central nervous system stimulating drug, which increases the level of neurotransmitter dopamine (DA) in the brain, by blocking the dopamine transporters (DAT) which is critical for DA homeostasis and neurocognitive function. Tat protein of HIV acts as an allosteric modulator of DAT, where as cocaine acts as reuptake inhibitor. When macrophages in the CNS are exposed to DA, their number increases. These macrophages release inflammatory mediators and neurotoxins, causing chronic neuroinflammation. Cocaine abuse during HIV infection enhances the production of platelet monocyte complexes (PMCs), which may cross transendothelial barrier, and result in HIV-associated neurocognitive disorder (HAND). HAND is characterized by neuroinflammation, including astrogliosis, multinucleated giant cells, and neuronal apoptosis that is linked to progressive virus infection and immune deterioration. Cocaine and viral proteins are capable of eliciting signaling transduction pathways in neurons, involving in mitochondrial membrane potential loss, oxidative stress, activation of JNK, p38, and ERK/MAPK pathways, and results in downstream activation of NF-κB that leads to HAND. Tat-induced inflammation provokes permeability of the blood brain barrier (BBB) in the platelet dependent manner, which can potentially be the reason for progression to HAND during HIV infection. A better understanding on the role of cocaine in HIV infection can give a clue in developing novel therapeutic strategies against HIV-1 infection

    AIM: To investigate the prevalence and risk factors of HCV/HIV coinfection in injection drug abusers (IDAs) in Lianshan Yi Autonomous Prefecture of Sichuan province, China.METHODS: From November 8, 2002 to November 29, 2002,a community-based survey was conducted to investigate the demographic characteristics, patterns of shared injectors devices and sexual behaviors in IDAs. Blood samples were also collected to test HCV and HIV infection. A total of 379subjects were recruited in the study through community outreach and peer recruiting methods.RESULTS: Of the 379 IDAs, the HCV prevalence and HIV prevalence were 71.0% and 11.3%, respectively, and HCV/HIV coinfection was 11.3%. HCV infection was found in 100% and 67.3% of HIV-positive and HIV-negative IDAs,respectively. HIV prevalence was 16.0% in HCV positive IDAs while none of the HCV negative IDAs was positive for HIV. Ethnicity, shared needles or syringes and cotton in the past 3 mo and syphilis infection were associated with HCV/HIV coinfection shown by univariate analysis using chi-square test. Multivariate logistic regression analysis showed that shared needles or syringes in the past 3 mo (Odds ratio=3.121, 95% CI: 1.278-7.617, P<0.05) and syphilis infection (Odds ratio=2.914, 95% CI: 1.327-6.398,P<0.01) were significantly associated with HCV infection.No statistically significant association was found in univariate analysis between sexual behaviors and HCV/HIV coinfection.CONCLUSION: Shared needles and syringes in the past 3 mo and syphilis infection were significantly associated with HCV infection. Further sero-epidemiological prospective cohort studies should be conducted to clarify the impact of syphilis and high risk sexual behaviors on HCV transmission through unprotected sexual intercourse.

    Talaromyces (Penicillium) marneffei is an important pathogenic thermally dimorphic fungus causing systemic mycosis in Southeast Asia. The clinical significance of T. marneffei became evident when the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome epidemic arrived in Southeast Asia in 1988. Subsequently, a decline in the incidence of T. marneffei infection among HIV-infected patients was seen in regions with access to highly active antiretroviral therapy and other control measures for HIV. Since the 1990s, an increasing number of T. marneffei infections have been reported among non-HIV-infected patients with impaired cell-mediated immunity. Their comorbidities included primary adult-onset immunodeficiency due to anti-interferon-gamma autoantibodies and secondary immunosuppressive conditions including other autoimmune diseases, solid organ and hematopoietic stem cell transplantations, T-lymphocyte-depleting immunsuppressive drugs and novel anti-cancer targeted therapies such as anti-CD20 monoclonal antibodies and kinase inhibitors. Moreover, improved immunological diagnostics identified more primary immunodeficiency syndromes associated with T. marneffei infection in children. The higher case-fatality rate of T. marneffei infection in non-HIV-infected than HIV-infected patients might be related to delayed diagnosis due to the lack of clinical suspicion. Correction of the underlying immune defects and early use of antifungals are important treatment strategies. Clinicians should be familiar with the changing epidemiology and clinical management of T. marneffei infection among non-HIV-infected patients. PMID:26956447

    Full Text Available Human immunodeficiency virus (HIV is known to influence the natural history of infections with certain hepatitis viruses and interactions between HIV and hepatitis viruses may potentiate HIV replication. There is high degree of epidemiological similarity between hepatitis B virus and HIV as regard to high-risk group and route of transmission. Transmission of hepatitis C virus (HCV through blood transfusion and intravenous drug abuse is well documented. Present study deals with the study of concurrent infection of HBV and HCV with HIV infection. In the study of 110 HIV seropositive patients, 34(30.4% were positive for HBV and 8(7.27% for HCV. The difference of concomitant infection was highly significant compared to controls. (p value < 0.0001. Heterosexual high risk behaviour was observed in 89(80.91% of 110 HIV positive patients, out of which 23(25.8% and 5(5.62% were HBsAg and anti-HCV positive respectively. History of transmission was unclear in remaining patients. Concomitant infection of HIV and HBV was found to be significantly more in the symptomatic group (40.68% compared to asymptomatic group (19.6%. As HIV infection is known to affect the natural history of both HBV and HCV infection, screening of their concurrent association is necessary.

    In Canada, the Aboriginal community is most at risk for HIV infection. Aboriginal peoples have disproportionately high rates of violence, drug use, and challenging socioeconomic circumstances. All of this is related to a history of colonization that has left Aboriginal people vulnerable to HIV infection through unsafe sex, needle sharing, and lack of access to health promotion and education. Aboriginal women are at particular risk for HIV infection. They experience a disproportionate degree of trauma, which is associated with colonization, high rates of childhood sexual abuse, and illicit drug use. A history of trauma impacts on access to health care, uptake of antiretroviral therapy, and mortality and morbidity in people with HIV. We describe the case of a 52-year-old, HIV-infected Aboriginal woman. We review the current evidence related to her case, including colonization, intersectionality, post-traumatic stress disorder, depression, revictimization, and substance use. PMID:24012166

    International Nuclear Information System (INIS)

    At the Armed Forces Institute of Pathology, Rawalpindi, facilities for HIV screening are available since 1987. So far, 54, 170 individuals have been tested. These included 48235 blood donors, 3369 persons proceeding abroad, 561 patients of venereal diseases, 350 Lymphoma cases, 21 deportees from the UAE, 460 clinically suspected cases of AIDS, 735 persons who were worried about HIV infection and 439 family members of HIV positive cases. A total of 30 cases were positive for anti-HIV on a strict protocol, which included screening tests followed by confirmatory tests including Western blot for HIV antibodies. The mode of HIV transmission was ascertained after a detailed history of all seropostive cases. It was found that in 24 cases the virus was acquired through sexual contact with high risk persons, which was homosexual in 3, heterosexual in 17, and bisexual in 4 cases. In 4 cases, the infection was acquired through blood transfusion, one child was infected through breast feeding, whereas only in one case the exact mode of HIV transmission was unclear. Out of 30 HIV positive cases, only three cases acquired the disease within Pakistan, 20 had acquired HIV infection during their stay in the Gulf states, while few cases had it from other countries (Saudi Arabia 1, Greece 1, France 2, S E Asia 3).

    2016-09-01

    Access to high-quality reproductive health care is important for adolescents and young adults with HIV infection to prevent unintended pregnancies, sexually transmitted infections, and secondary transmission of HIV to partners and children. As perinatally HIV-infected children mature into adolescence and adulthood and new HIV infections among adolescents and young adults continue to occur in the United States, medical providers taking care of such individuals often face issues related to sexual and reproductive health. Challenges including drug interactions between several hormonal methods and antiretroviral agents make decisions regarding contraceptive options more complex for these adolescents. Dual protection, defined as the use of an effective contraceptive along with condoms, should be central to ongoing discussions with HIV-infected young women and couples wishing to avoid pregnancy. Last, reproductive health discussions need to be integrated with discussions on HIV care, because a reduction in plasma HIV viral load below the level of detection (an "undetectable viral load") is essential for the individual's health as well as for a reduction in HIV transmission to partners and children.

    Full Text Available The Human Immunodeficiency Virus (HIV is a RNA retrovirus which causes the clinical disease termed the acquired immunodeficiency syndrome (AIDS. Mother-to-child transmission is the main source of spreading HIV infection to the child with frequency is as high as 25-30%. This may occurred because of the intrapartum maternal blood exposure, infected genital tract secretions and during breastfeeding. The right combination of ARV treatment and elective section caesarean delivery has been proved to reduce the mother-to-child transmission of HIV infection prevalence and preventing obstetric complications significantly. Consultation and follow up with specialists is highly recommended.

    Recently there has been increasing public concern regarding escalating child sexual abuse (CSA) in the sub-Saharan Africa. Medical consequences of child sexual abuse (CSA) include sexually transmitted infection (STI) and human immune virus (HIV) infection. The purpose of the study was to review literature on CSA and associated STI/HIV in the sub-Saharan Africa. The study covered the 23-year period from 1980 to 2003. The mean age of the child victims was 8 years. The incidence of penetrative sex in the studies ranged from 70 to 97%. Physical signs of CSA included genital or anal injuries, perineal trauma, and vesico-vaginal or recto-vaginal fistula. The incidence of STD varied according to whether the study was retrospective or prospective. Ten percent to 67% of children with STD had been sexually abused while 15 to 30% of sexual abuse incidents were associated with STD. The prevalence of HIV ranged from 3% in Togo to 37.5% in Cameroon. Most alleged child abusers were adult males known by the child, i.e., family members (30-60%), instructors or teachers, household personnel or neighbours. Some acts were motivated by traditional practices such as early, forced marriage and beliefs such as presumed benefits of sex with virgin children (cure for STI/HIV/STD, magic powers or wealth). This study shows that CSA is widespread throughout sub-Saharan Africa. Most problem involving CSA in sub-Saharan Afica have not been documented. Knowledge about the extent and special aspects of CSA in Africa can be useful for implementation of suitable management measures.

  13. NKT cells in HIV-1 infection

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Natural killer T (NKT) cells are a unique T cell population that have important immunoregulatory functions and have been shown to be involved in host immunity against a range of microorganisms. It also emerges that they might play a role in HIV-1 infection, and therefore be selectively depleted during the early stages of infection. Recent studies are reviewed regarding the dynamics of NKT depletion during HIV-I infection and their recovery under highly active antiretrovirai treatment (HAART). Possible mechanisms for these changes are proposed based on the recent developments in HIV pathogenesis. Further discussions are focused on HIV's disruption of NKT activation by downregulating CDId expression on antigen presentation cells (APC). HIV-1 protein Nefis found to play the major role by interrupting the intraceilular trafficking of nascent and recycling CDId molecules.

    . Taking effective preventive measures against drug abuse has led to the decrease in the incidence of HIV-infection among this group of risk and changes of transmission routes. In 2015 in the structure of the leading transmission routes there were (22.6 ± 1.8 % of parenteral and (56.9 ± 2.1 % of sexual cases (p<0.05. These data indicate that the implementation tract infection due to injecting drug use leads to a concentrated stage of the HIV epidemic. At the same time the increase in the proportion of sexual transmission increase in the number of infected women indicate a threat to the output of the epidemic risk groups to the general set of the population. Conclusions. 1. The incidence of HIV-infection in the region was in several times lower than on the whole in Ukraine (accordingly 2.4 - 23.7 and 10.6 - 47.1 per 100 000 population. 2. Carried out research in the region revealed the peculiarities of the epidemic process of HIV-infection. So the level of growth of newly registered cases of HIV-infection from 0.1 per 100 000 population in 1995 to 20.5 per 100 000 population in 2015 was set (the growth rate was +7.0 %; a gradual change in the sexual spectrum of HIV-infected people (women from 12.9 % to 41.0 % and men from 87.1 % to 59.0 % and the structure of the leading transmission routes (parenteral from 77.1 % to 22.6% and sexual from 5.7 % to 59.6 %; involvement in the epidemic process of all age groups with a predominance of the most working-age population 25 – 49 years. 3. The HIV epidemic is concentrated on the most vulnerable groups of population, but there is a risk of generalized spreading of HIV among the population. 4. Epidemiological surveillance of HIV infection must be adapted to the local epidemiological conditions, and preventive measures aimed at the timely detection of infection cases and the suspension of the epidemic.

    2002-07-01

    Approximately 400,000 individuals in the United States are co-infected with hepatitis C virus (HCV) and human immunodeficiency virus type 1 (HIV-1) and it is likely that almost one in two of these subjects consumes alcohol. The majority of these patients suffer an accelerated course of liver disease as manifested by the onset of cirrhosis within 5 to 10 years of developing HCV infection, as well as an increased risk of developing hepatocellular carcinoma (HCC). It is thought that chronic alcohol abuse mediates liver damage as a result of increased production of free radicals and proinflammatory cytokines. In the setting of chronic HCV infection, alcohol ingestion has an additional effect of diminishing immune clearance and increasing viral burden to hasten the onset of cirrhosis and HCC. Likewise, chronic HCV and HIV-1 co-infection results in a net increase in HCV burden; higher prevalence rates of HCV transmission to sexual partners and offspring, as well as an accelerated progression to end stage liver disease as compared to individuals with HCV infection alone. Thus, the synergistic effects of alcohol abuse and HIV-1 greatly impact on the morbidity and mortality for patients with HCV coinfection. Ultimately, this cumulative disease process will require far more aggressive management with abstinence and counseling for alcohol abuse; highly active antiretroviral therapy (HAART) for HIV infection and combination anti-viral therapy for HCV infection to stem the rapid progression to end stage liver disease.

    Substance abuse is a risk factor for HIV infection and progression to AIDS. Recent evidence establishes that cocaine use promotes brain perivascular macrophage infiltration and microglia activation. The lysosomal protease cathepsin B is increased in monocytes from patients with HIV dementia and its secretion induces 10-15% of neurotoxicity. Here we asked if cocaine potentiates cathepsin B secretion from HIV-infected monocyte-derived macrophages (MDM) and its effect in neuronal apoptosis. Samples of plasma, CSF, and post-mortem brain tissue from HIV positive patients that used cocaine were tested for cathepsin B and its inhibitors to determine the in vivo relevance of these findings. MDM were inoculated with HIV-1ADA, exposed to cocaine, and the levels of secreted and bioactive cathepsin B and its inhibitors were measured at different time-points. Cathepsin B expression (p cocaine treated MDM compared with HIV-infected cocaine negative controls. Increased levels of cystatin B expression was also found in supernatants from HIV-cocaine treated MDM (p cocaine users over non-drug users. Our results demonstrated that cocaine potentiates cathepsin B secretion in HIV-infected MDM and increase neuronal apoptosis. These findings provide new evidence that cocaine synergize with HIV-1 infection in increasing cathepsin B secretion and neurotoxicity. PMID:25209871

    Early identification and intervention for victims of child sexual abuse (CSA) is essential to halting the spread of HIV in Latino populations because children who are sexually abused are at an increased risk of contracting HIV. The recent influx of unaccompanied children into the United States exposed histories of victimization, vulnerability to CSA, and suggested an epidemic of CSA in Latin America. CSA has been identified as a contributory event to HIV infection. The aim of our research was to identify factors associated with CSA and Latin Americans. A systematic review and a document search were conducted on factors associated with CSA in Latin America. Victimization was associated with lifelong risk factors for HIV. Males were consistently underrepresented in the published CSA literature and machismo attitudes may contribute to abuses of sexual power by males and contribute to males not reporting or under-reporting victimization.

  11. Thymic function in HIV-infection.

    2013-04-01

    This thesis is based on seven previously published articles. The work was performed during my employment at The Department of Infectious Diseases, Copenhagen University Hospital, Hvidovre, as a scholarship student from 2000-2001 and as a research assistant in the period 2004-2010. HIV-infection is characterized by CD4+ cell depletion. The differences between patients in the degree of CD4+ cell recovery upon treatment with highly active antiretroviral therapy (HAART) may in part be due to differences in the supply of naïve CD4+ cells from the thymus. The thymus atrophies with increasing age for which reason the adult thymus was previously assumed to be without function. The aim of these investigations was to examine the role of the thymus in different aspects of HIV-infection: In adult HIV-infected patients, during HIV-positive pregnancy, and in HIV-exposed uninfected (HIV-EU) children born to HIV-infected mothers. Thymic size and output were determined in 25 adult HIV-infected patients receiving HAART and in 10 controls. Larger thymic size was associated with higher CD4 counts and higher thymic output. Furthermore, patients with abundant thymic tissue seemed to have broader immunological repertoires, compared with patients with minimal thymic tissue. The study supports the mounting evidence of a contribution by the adult thymus to immune reconstitution in HIV-infection. In a follow-up study conducted till 5 years of HAART, the importance of the thymus to the rate of cellular restoration was found to primarily lie within the first two years of HAART. The effect of recombinant human growth hormone (rhGH) was then investigated in a randomized, double-blinded placebo controlled trial in 46 adult HIV-infected patients on HAART. Daily treatment with a low dose of rhGH of 0.7mg for 40 weeks stimulated thymopoiesis as expressed by thymic size, density, and output strongly supporting the assumption that rhGH possesses the potential to stimulate the ageing thymus, holding

    2014-06-01

    Full Text Available HIV infection has been studied by various sciences, since it articulates biological, clinical and social realities. Since the time of its appearance to the present, advances in the treatment of HIV infection have been notorious and fascinating. Antiretroviral therapy promotes an improved quality of life for patients and increases life expectancy but has had difficulties with treatment associated behaviour, i.e., adherence to treatment. The aim of this study was to evaluate the influence of psychopathological and behavioral determinants of HIV-positive patients. We have found that behavioral risk pattern exists in both genders and predominantely sexual in nature. Men are more compliant than women regarding treatment, but exhibit high levels in the hostility dimension. Indeed, in HIV infection, there's a limited perception of control over disease, which contributes to an adaptation guided by feelings of inadequacy. We underline the vulnerability in the female gender, since women had a behavioral pattern of significant risk.

    A typical HIV infection response consists of three stages: an initial acute infection, a long asymptomatic period and a final increase in viral load with simultaneous collapse in healthy CD4+T cell counts. The majority of existing mathematical models give a good representation of either the first two stages or the last stage of the infection. Using macrophages as a long-term active reservoir, a deterministic model is proposed to explain the three stages of the infection including the progress...

  16. The stochastic dance of early HIV infection

    Science.gov (United States)

    Merrill, Stephen J.

    2005-12-01

    The stochastic nature of early HIV infection is described in a series of models, each of which captures aspects of the dance of HIV during the early stages of infection. It is to this highly variable target that the immune response must respond. The adaptability of the various components of the immune response is an important aspect of the system's operation, as the nature of the pathogens that the response will be required to respond to and the order in which those responses must be made cannot be known beforehand. As HIV infection has direct influence over cells responsible for the immune response, the dance predicts that the immune response will be also in a variable state of readiness and capability for this task of adaptation. The description of the stochastic dance of HIV here will use the tools of stochastic models, and for the most part, simulation. The justification for this approach is that the early stages and the development of HIV diversity require that the model to be able to describe both individual sample path and patient-to-patient variability. In addition, as early viral dynamics are best described using branching processes, the explosive growth of these models both predicts high variability and rapid response of HIV to changes in system parameters.In this paper, a basic viral growth model based on a time dependent continuous-time branching process is used to describe the growth of HIV infected cells in the macrophage and lymphocyte populations. Immigration from the reservoir population is added to the basic model to describe the incubation time distribution. This distribution is deduced directly from the modeling assumptions and the model of viral growth. A system of two branching processes, one in the infected macrophage population and one in the infected lymphocyte population is used to provide a description of the relationship between the development of HIV diversity as it relates to tropism (host cell preference).

    Human immunodeficiency virus (HIV) infection includes acute, early, chronic, and late stages. Acute HIV infection lasts approximately 3 weeks and early HIV infection, which includes acute HIV infection, lasts approximately 7 weeks. Many testing and blood screening algorithms detect HIV antibodies about 3 weeks after HIV infection. Incidence estimates are based on results of modeling, cohort studies, surveillance, and/or assays. Viral load is the key modifiable risk factor for HIV transmission and peaks during acute and early HIV infection. Empirical evidence characterizing the impact of acute and early HIV infection on the spread of the HIV epidemic are limited. Time trends of HIV prevalence collected from concentrated and generalized epidemics suggest that acute and early HIV infection may have a limited role in population HIV transmission. Collectively, these data suggest that acute and early HIV infection is relatively short and does not currently require fundamentally different programmatic approaches to manage the HIV/AIDS epidemic in most settings. Research and surveillance will inform which epidemic contexts and phases may require tailored strategies for these stages of HIV infection.

    The prevalence of HIV infection in dialysis populations varies according to different countries and geographic areas. We performed a nationwide epidemiological study by means of a questionnaire in the period from January 1990 to December 1995. Questions were about whether and which HIV tests were performed and which preventive measures were adopted. A separate survey evaluated the data the HIV-positive patients. Only 62% of the centers responded to the questionnaire, corresponding to 21,500 dialysis patients in 1990 and 27,000 in 1995. The prevalence of HIV-positive subjects was 0,13% for 1995. A total of 48 patients with HIV infection were identified: risk factors were drug abuse in 16 cases, homosexuality in 9, heterosexual contact in 8, transfusion in 7, renal transplant in 3 and unknown cause in 5. Forty-five patients were on hemodialysis, and 3 were receiving peritoneal dialysis. At follow-up, 19 patients died: infection and malnutrition were the most frequent causes of death. The death rate of patients who were already HIV positive when dialysis was started (group 1, 29 cases) was 19.36 deaths/1,000 patient/month. The correlations, performed only for group 1, showed a significantly worse prognosis for patients with CD4 HIV infection in the dialysis population is low, and the outcome of HIV-positive patients in dialysis was found to be better than earlier literature reports. The use of chronic dialysis for HIV patients with uremia should not be discouraged.

    Full Text Available The nervous system plays an important role in HIV infection. The purpose of this review is to discuss the indications for cerebrospinal fluid (CSF analysis in HIV infection in clinical practice. CSF analysis in HIV infection is indicated for the diagnosis of opportunistic infections and co-infections, diagnosis of meningitis caused by HIV, quantification of HIV viral load, and analysis of CNS HIV compartmentalization. Although several CSF biomarkers have been investigated, none are clinically applicable. The capacity of HIV to generate genetic diversity, in association with the constitutional characteristics of the CNS, facilitates the generation of HIV quasispecies in the CNS that are distinct from HIV in the systemic circulation. CSF analysis has a well-defined and valuable role in the diagnosis of CNS infections in HIV/AIDS patients. Further research is necessary to establish a clinically applicable biomarker for the diagnosis of HIV-associated neurocognitive disorders.

    Full Text Available Human Immunodeficiency Virus (HIV and Mycobacterium tuberculosis (M.tb are among the most lethal human pathogens worldwide, each being responsible for around 1.5 million deaths annually. Moreover, synergy between acquired immune deficiency syndrome (AIDS and tuberculosis (TB has turned HIV/M.tb co-infection into a major public health threat in developing countries. In the past decade, autophagy, a lysosomal catabolic process, has emerged as a major host immune defense mechanism against infectious agents like M.tb and HIV. Nevertheless, in some instances, autophagy machinery appears to be instrumental for HIV infection. Finally, there is mounting evidence that both pathogens deploy various countermeasures to thwart autophagy. This mini-review proposes an overview of the roles and regulations of autophagy in HIV and M.tb infections with an emphasis on microbial factors. We also discuss the role of autophagy manipulation in the context of HIV/M.tb co-infection. In future, a comprehensive understanding of autophagy interaction with these pathogens will be critical for development of autophagy-based prophylactic and therapeutic interventions for AIDS and TB.

    We have observed significantly increased HIV infection in HIV infected macrophages in the presence of cocaine that could be due to the downregulation of BST2 restriction factor in these cells. In human inflammasome PCR array, among different involved in inflammasome formation, in HIV infected macrophages in the presence of cocaine, we have observed significant upregulation of NLRP3, AIM2 genes and downstream genes IL-1β and PTGS2. Whereas negative regulatory gene MEFV was upregulated, CD40LG and PYDC1 were significantly downregulated. Among various NOD like receptors, NOD2 was significantly upregulated in both HIV alone and HIV plus cocaine treated cells. In the downstream genes, chemokine (C-C motif) ligand 2 (CCL2), CCL7 and IL-6 were significantly up regulated in HIV plus cocaine treated macrophages. We have also observed significant ROS production (in HIV and/or cocaine treated cells) which is one of the indirect-activators of inflammasomes formation. Further, we have observed early apoptosis in HIV alone and HIV plus cocaine treated macrophages which may be resultant of inflammasome formation and cspase-1 activation. These results indicate that in case of HIV infected macrophages exposed to cocaine, increased ROS production and IL-1β transcription serve as an activators for the formation of NLRP3 and AIM2 mediated inflammasomes that leads to caspase 1 mediated apoptosis.

    Substance abuse is a major barrier in eradication of the HIV epidemic because it serves as a powerful cofactor for viral transmission, disease progression, and AIDS-related mortality. Cocaine, one of the commonly abused drugs among HIV-1 patients, has been suggested to accelerate HIV disease progression. However, the underlying mechanism remains largely unknown. Therefore, we tested whether cocaine augments HIV-1–associated CD4+ T-cell decline, a predictor of HIV disease progression. We exami...

    In the developed world, HIV infection is now well managed with very effective and less toxic antiretroviral treatment. HIV-positive patients therefore are living longer, but are now faced by challenges associated with aging. Several non-AIDS associated morbidities are increased in this population......, including cardiovascular disease (CVD). It is suggested that CVD occurs earlier among HIV-positive patients compared with HIV-negative patients, and at a higher rate. Several factors have been proposed to contribute to this. First, the traditional CVD risk factors are highly prevalent in this population....... High rates of smoking, dyslipidaemia and a family history of CVD have been reported. This population is also aging, with estimates of more than 25% of HIV-positive patients in the developed world being over the age of 50.

    Mental health and substance abuse problems are highly prevalent among HIV-infected men who have sex with men (MSM) and frequently interfere with antiretroviral therapy (ART) adherence. Novel interventions that address underlying psychosocial health problems are necessary for improving ART adherence to enhance HIV-related health outcomes and suppress HIV viral load in an effort to prevent transmission to uninfected partners. This brief review describes the mental health problems and specific substances that pose the greatest threat to medication adherence among MSM and summarizes findings from recent intervention trials that simultaneously address ART adherence and comorbid psychosocial factors among HIV-infected MSM.

The majority of existing mathematical models give a good representation of either the first two stages or the last stage of the infection. Using macrophages as a long-term active reservoir, a deterministic model is proposed to explain the three stages of the infection including the progression to AIDS. Simulation results illustrate how chronic infected macrophages can explain the progression to AIDS provoking viral explosion. Further simulation studies suggest that the proposed model retains its key properties even under moderately large parameter variations. This model provides important insights on how macrophages might play a crucial role in the long term behavior of HIV infection. PMID:23238280

    HIV involvement of the CNS continues to be a significant problem despite successful use of combination antiretroviral therapy (cART). Drugs of abuse can act in concert with HIV proteins to damage glia and neurons, worsening the neurotoxicity caused by HIV alone. Methamphetamine (METH) is a highly addictive psychostimulant drug, abuse of which has reached epidemic proportions and is associated with high-risk sexual behavior, increased HIV transmission, and development of drug resistance. HIV infection and METH dependence can have synergistic pathological effects, with preferential involvement of frontostriatal circuits. At the molecular level, epigenetic alterations have been reported for both HIV-1 infection and drug abuse, but the neuropathological pathways triggered by their combined effects are less known. We investigated epigenetic changes in the brain associated with HIV and METH. We analyzed postmortem frontal cortex tissue from 27 HIV seropositive individuals, 13 of which had a history of METH dependence, in comparison to 14 cases who never used METH. We detected changes in the expression of DNMT1, at mRNA and protein levels, that resulted in the increase of global DNA methylation. Genome-wide profiling of DNA methylation in a subset of cases, showed differential methylation on genes related to neurodegeneration; dopamine metabolism and transport; and oxidative phosphorylation. We provide evidence for the synergy of HIV and METH dependence on the patterns of DNA methylation on the host brain, which results in a distinctive landscape for the comorbid condition. Importantly, we identified new epigenetic targets that might aid in understanding the aggravated neurodegenerative, cognitive, motor and behavioral symptoms observed in persons living with HIV and addictions.

    More than 1 million HIV-exposed, uninfected infants are born annually to HIV-positive mothers worldwide. This growing population of infants experiences twice the mortality of HIV-unexposed infants. We found that although there were very few differences seen in the microbiomes of mothers with and without HIV infection, maternal HIV infection was associated with changes in the microbiome of HIV-exposed, uninfected infants. Furthermore, we observed that human breast milk oligosaccharides were associated with bacterial species in the infant microbiome. The disruption of the infant's microbiome associated with maternal HIV infection may contribute to the increased morbidity and mortality of HIV-exposed, uninfected infants.

    Cyclophilin B (CypB) is a member of the immunophilin family and intracellular chaperone. It predominantly localizes to the ER, but also contains a nuclear localization signal and is secreted from cells. CypB has been shown to interact with the Gag protein of human immunodeficiency type 1 (HIV-1). Several proteomic and genetic studies identified it as a potential factor involved in HIV replication. Herein, we show that over-expression of CypB enhances HIV infection by increasing nuclear import of viral DNA. This enhancement was unaffected by cyclosporine treatment and requires the N-terminus of the protein. The N-terminus contains an ER leader sequence, putative nuclear localization signal, and is required for secretion. Deletion of the N-terminus resulted in mislocalization from the ER and suppression of HIV infection. Passive transfer experiments showed that secreted CypB did not impact HIV infection. Combined, these experiments show that intracellular CypB modulates a pathway of HIV nuclear import. PMID:26774171

    Interaction of the chemokine CXCL12 with its receptor CXCR4 promotes neuronal function and survival during embryonic development and throughout adulthood. Previous studies indicated that μ-opioid agonists specifically elevate neuronal levels of the protein ferritin heavy chain (FHC), which negatively regulates CXCR4 signaling and affects the neuroprotective function of the CXCL12/CXCR4 axis. Here, we determined that CXCL12/CXCR4 activity increased dendritic spine density, and also examined FHC expression and CXCR4 status in opiate abusers and patients with HIV-associated neurocognitive disorders (HAND), which is typically exacerbated by illicit drug use. Drug abusers and HIV patients with HAND had increased levels of FHC, which correlated with reduced CXCR4 activation, within cortical neurons. We confirmed these findings in a nonhuman primate model of SIV infection with morphine administration. Transfection of a CXCR4-expressing human cell line with an iron-deficient FHC mutant confirmed that increased FHC expression deregulated CXCR4 signaling and that this function of FHC was independent of iron binding. Furthermore, examination of morphine-treated rodents and isolated neurons expressing FHC shRNA revealed that FHC contributed to morphine-induced dendritic spine loss. Together, these data implicate FHC-dependent deregulation of CXCL12/CXCR4 as a contributing factor to cognitive dysfunction in neuroAIDS.

  20. Insulin resistance and diabetes in HIV infection.

    Science.gov (United States)

    Das, Satyajit

    2011-09-01

    Insulin resistance is an important and under recognized consequence of HIV treatment. Different studies have yielded widely varying estimates of the prevalence of impaired glucose metabolism in people on highly active antiretroviral therapy (HAART). The risk increases further with hepatitis C co infection. Although Protease inhibitors (PIs) are the main drug class implicated in insulin resistance, some studies have shown an association of increased risk of diabetes with cumulative exposure of nucleoside reverse transcriptase inhibitors (NRTIs). The effect of switching to other antiretrovirals has not been fully determined and the long-term consequences of insulin resistance in this population are not known. Treatment of established diabetes mellitus should generally follow existing guidelines. It is therefore reasonable to recommend general measures to increase insulin sensitivity in all patients infected with HIV, such as regular aerobic exercise and weight reduction for overweight persons. The present review article has the information of some recent patents regarding the insulin resistance in HIV infection. PMID:21824074

    Olowu, 'Dejo

    2011-09-01

    The article posits that imbalances in gender relations are influencing two distinctive yet connected crises for women in Lesotho: the HIV epidemic and spousal abuse. The overarching premise is that as spousal abuse is increasingly recognised and as HIV infections spread, responses to the phenomenon do not reflect the related risks and consequences in married women's lives. This article underscores the nexus of connections between HIV and spousal abuse in Lesotho, identifying potential areas for pragmatic state-led responses. Applying a rights-based approach, it assesses women's vulnerability to each problem at the individual, societal and programmatic levels, noting that there are both direct and underlying factors heightening risks for women. The article asks, what is the value added by a rights-based approach to the subject under discourse? And, how can a rights-based approach be translated into practical tools for planning, monitoring and evaluating projects and programmes aimed at tackling the multifaceted risks and challenges of HIV and spousal abuse confronting women in Lesotho? In response to these questions, the author identifies three trajectories of opportunities for an integrated, comprehensive response. The unmistakable anchor of the article's propositions is the rights-based approach. Although the discussion focuses on Lesotho, the implications for the broader African region cannot be overemphasised in light of commonly shared experiences pertaining to the severe difficulties posed by spousal abuse and HIV.

    To examine neuropsychological deficits associated with the human immunodeficiency virus (HIV), 25 asymptomatic homosexual men and sexual partners of intravenous drug users and 25 seronegative homosexual men and nonhigh-risk heterosexuals were assessed on measures of fine motor control, visual scanning, attention, depression, and global psychological functioning. Analysis suggested that HIV infection is associated with reduced fine motor control. Seropositivity is associated with elevated depression and global psychological maladjustment. When depression and global adjustment were analyzed as covariates, motor slowing was evident in the seropositive group. These findings suggest an association between motor slowing and HIV infection in asymptomatic subjects and point to the necessity of measuring affect at least as a control variable. Further study is needed to determine whether the fine motor deficit evident in this sample is limited to distinct subgrouping of the over-all sample. PMID:2762096

    We report the case of a 47-year-old female patient with rheumatoid arthritis and HIV infection presenting with a 3-week history of a painful swollen knee, increased serum inflammatory markers, and a low CD4 lymphocyte count. The diagnosis of TB arthritis was made by synovial fluid culture, GeneXpert/PCR, and confirmed by histopathology of a synovial biopsy. A mini literature review suggests that although HIV infection is associated with extrapulmonary TB, osteoarticular TB is a relatively unusual presentation in an HIV positive patient. The diagnostic utility of the GeneXpert test is explored. We also describe the patient's good response to an intra-articular corticosteroid injection in combination with standard anti-TB therapy.

    Full Text Available Abstract Background While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL in HIV. Methods The present study focused on HIV in the context of childhood trauma and its impact on functionality and Quality of Life (QoL by evaluating 85 HIV-positive (48 with childhood trauma and 37 without and 52 HIV-negative (21 with childhood trauma and 31 without South African women infected with Clade C HIV. QoL was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q, the Patient's Assessment of Own Functioning Inventory (PAOFI, the Activities of Daily Living (ADL scale and the Sheehan Disability Scale (SDS. Furthermore, participants were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D and the Childhood Trauma Questionnaire (CTQ. Results Subjects had a mean age of 30.1 years. After controlling for age, level of education and CES-D scores, analysis of covariance (ANCOVA demonstrated significant individual effects of HIV status and childhood trauma on self-reported QoL. No significant interactional effects were evident. Functional limitation was, however, negatively correlated with CD4 lymphocyte count. Conclusions In assessing QoL in HIV-infected women, we were able to demonstrate the impact of childhood trauma on functional limitations in HIV.

    Fosamprenavir is a protease inhibitor (PI) approved for the treatment of HIV-1 infection. Fosamprenavir is a prodrug of amprenavir developed to reduce the pill burden yet maintain the unique resistance pattern and efficacy associated with amprenavir. In a head-to-head, noninferiority trial in antiretroviral treatment-naive HIV-infected patients, the antiviral efficacy and tolerability of ritonavir-boosted fosamprenavir was not inferior to ritonavir-boosted lopinavir, when the PIs were combined with two other nucleoside reverse transcriptase inhibitors. There are fewer studies published about fosamprenavir use in antiretroviral treatment-experienced HIV-infected patients. The high genetic barrier to the development of resistance to fosamprenavir and the low level of cross-resistance between ritonavir-boosted fosamprenavir and other PI regimens are notable. As with amprenavir, gastrointestinal disturbance and rash are the most frequent short-term treatment-limiting events with fosamprenavir. Treatment with ritonavir-boosted fosamprenavir can produce a durable response. To date, fosamprenavir is one of the recommended preferred PI components for the treatment of antiretroviral-naive HIV-infected patients.

    AIM: Recent studies in Iran has shown that prevalence of hepatitis C virus (HCV) infection among Iranian prisoners is high, in spite of low HCV seroprevalence in general population.METHODS: This study was carried out in the central prison of Hamedan - Iran, in year 2002. Inmates were interviewed using a standard questionnaire including demographic,imprisonment history and HCV-related risk behaviors items. Thereafter, the sera drawn from the participants were tested for anti-HIV and anti-HCV antibodies.RESULTS: A total number of 427 drug abuser inmates participated in our study. Three hundred and ninety-seven (93%) were men and 30 (7%) were women. Total number of Ⅳ drug abusers (IDA) and non-Ⅳ drug abusers (NIDA)was 149 (34.9%) and 278 (65.1%), respectively. The overall rate of antibody positivity among inmates was 0.9% for HIV and 30% for HCV. Of all IDAs, 31.5% and of NIDAs, 29.1% had serological evidence of HCV infection.CONCLUSION: The seroprevalence of HCV infection among drug abuser prisoners in comparison with the general population in Iran, is very high (30% vs in italics 0.2%).Our results indicate the importance of policies to prevent transmission of HCV infection during and following incarceration.

    Gender-based violence (GBV) is common among women with and at risk for HIV, yet little is known about the GBV associated psychological factors that could be modifiable through behavioral interventions. The current study examined the associations between some of these psychological factors (i.e., hopelessness, consideration of future consequences, self esteem), mental health symptoms, substance abuse, and GBV among a sample of 736 HIV-infected and sociodemographically similar uninfected participants in the Women's Interagency HIV Study (WIHS). Results indicated high rates of lifetime GBV among the sample (58%), as well as high rates of childhood sexual abuse (CSA) (22.2%). HIV-infected women were more likely to be hopeless and to experience lower consideration of future consequences as compared to uninfected women. Multivariable analysis indicated that current non-injection drug use and a history of injection drug use were the main correlates of GBV and CSA, even when other psychosocial variables were included in analytic models. Being born outside of the US reduced the likelihood of GBV and CSA. Future research directions and intervention implications are discussed. PMID:24724987

    Full Text Available The oral microbial community (microbiota plays a critical role in human health and disease. Alterations in the oral microbiota may be associated with disorders such as gingivitis, periodontitis, childhood caries, alveolar osteitis, oral candidiasis and endodontic infections. In the immunosuppressed population, the spectrum of potential oral disease is even broader, encompassing candidiasis, necrotizing gingivitis, parotid gland enlargement, Kaposi's sarcoma, oral warts and other diseases. Here, we used 454 pyrosequencing of bacterial 16S rRNA genes to examine the oral microbiome of saliva, mucosal and tooth samples from HIV-positive and negative children. Patient demographics and clinical characteristics were collected from a cross-section of patients undergoing routine dental care. Multiple specimens from different sampling sites in the mouth were collected for each patient. The goal of the study was to observe the potential diversity of the oral microbiota among individual patients, sample locations, HIV status and various dental characteristics. We found that there were significant differences in the microbiome among the enrolled patients, and between sampling locations. The analysis was complicated by uneven enrollment in the patient cohorts, with only five HIV-negative patients enrolled in the study and by the rapid improvement in the health of HIV-infected children between the time the study was conceived and completed. The generally good oral health of the HIV-negative patients limited the number of dental plaque samples that could be collected. We did not identify significant differences between well-controlled HIV-positive patients and HIV-negative controls, suggesting that well-controlled HIV-positive patients essentially harbor similar oral flora compared to patients without HIV. Nor were significant differences in the oral microbiota identified between different teeth or with different dental characteristics. Additional studies are

Nor were significant differences in the oral microbiota identified between different teeth or with different dental characteristics. Additional studies are needed to better

    Cognitive impairment is common in HIV-infected individuals, as is syphilis. Treponema pallidum, the bacterium that causes syphilis, invades the central nervous system early in disease. We hypothesized that HIV-infected patients with a history of syphilis or neurosyphilis would have more cognitive impairment than HIV-infected individuals without these infections. Eighty-two of 1574 enrollees in CHARTER, a prospective, observational study, had reactive serum rapid plasma reagin (RPR) tests. The...

    Objective:To determine the prevalence of HIV infection among homeless men and women and the related risk behaviors in Tehran, Iran. Methods: In 2007-2008, Tehran municipality stacked up 10 657 homeless men and women for assessment of HIV and began collaboration with Iranian Research Center for HIV/AIDS (IRCHA) departments to conduct HIV infection prevalence surveys in homeless populations. The results were analyzed for associations with demographic information, family support, status of drug abuse and relation with family and friends. Results:Overall HIV prevalence was 1.7%(95%confidence interval 1.4-1.9). Factors independently associated with HIV infection included history of using drugs [AOR 8.15 (4.86-13.67)], older age [AOR 1.80 (1.08-2.99) for 40- 55 yr], occupation [AOR 1.64 (1.19-2.24) for unemployed], and no relation with family [AOR 1.82 (1.30-2.54)]. Conclusions: This study supports the idea that injection drug use is contributing to the increased spread of HIV among Iranian homeless. Harm reduction programs should be expanded, particularly among homeless injection drug users.

Pediatric and perinatal HIVclinic in a tertiary pediatric hospital.Sixteen infants born to HIV positive mother enrolled in the preventionof mother to child transmission of HIV at our center were tested for HIV infection by HIV DNAPCR at 1.5 months, 3 months, 5.5 months and/or 7 months of age. Their HIV status was confirmedby an HIV ELISA test at 18 months of age by 2 different ELISA kits. Eight patients (50% had anegative HIV DNA PCR whereas 8 patients (50% had a positive DNA PCR of which 6 patients(75% had a false positive HIV DNA PCR and no false negative DNA PCR. Thus, the sensitivity ofHIV DNA PCR was 100% and specificity was 57.1% with a total efficiency of the test being62.5%. The efficiency of HIV DNA PCR at 1.5 months of age was 50%, at 3 months of age42.9%, at 5.5 months of age 60% and at 7 months of age was 100%. HIV DNA PCR has a highsensitivity but low specificity to diagnose HIV infection in infants less than 7 months of age. Hence,the results of the test have to be interpreted with caution in infants born to HIV positive mothers.

  16. Alcohol and cannabinoids differentially affect HIV infection and function of human monocyte-derived dendritic cells (MDDC

    Full Text Available During human immunodeficiency virus (HIV infection, alcohol has been known to induce inflammation while cannabinoids have been shown to have an anti-inflammatory role. For instance cannabinoids have been shown to reduce susceptibility to HIV-1 infection and attenuate HIV replication in macrophages. Recently, we demonstrated that alcohol induces cannabinoid receptors and regulates cytokine production by monocyte-derived dendritic cells (MDDC. However, the ability of alcohol and cannabinoids to alter MDDC function during HIV infection has not been clearly elucidated yet. In order to study the potential impact of alcohol and cannabinoids on differentiated MDDC infected with HIV, monocytes were cultured for 7 days with GM-CSF and IL-4, differentiated MDDC were infected with HIV-1Ba-L and treated with EtOH (0.1 and 0.2%, THC (5 and 10 uM, or JWH-015 (5 and 10 uM for 4-7 days. HIV infection of MDDC was confirmed by p24 and Long Terminal Repeats (LTR estimation. MDDC endocytosis assay and cytokine array profiles were measured to investigate the effects of HIV and substances of abuse on MDDC function. Our results show the HIV+EtOH treated MDDC had the highest levels of p24 production and expression when compared with the HIV positive controls and the cannabinoid treated cells. Although both cannabinoids, THC and JWH-015 had lower levels of p24 production and expression, the HIV+JWH-015 treated MDDC had the lowest levels of p24 when compared to the HIV+THC treated cells. In addition, MDDC endocytic function and cytokine production were also differentially altered after alcohol and cannabinoid treatments. Our results show a differential effect of alcohol and cannabinoids, which may provide insights into the divergent inflammatory role of alcohol and cannabinoids to modulate MDDC function in the context of HIV infection.

    Full Text Available Human Immunodeficiency Virus (HIV and other blood borne viral infections like hepatitis B virus (HBV and hepatitis C virus (HCV are major health issues especially in young and growing population of developing countries. All around the globe correctional facilities are known as potential source of spreading such disease. During summer 2002, HIV, HCV antibodies, hepatitis B surface (HBs antigen and rapid plasma reagin (RPR test were checked in venous blood samples of 252 injecting drug abuser prisoners from correctional facilities in southern Iran. Overall HIV, HCV and HBV infection rate was 15.1% (38/249, 64.8% (163/249, and 4.7% (12/249, respectively. HCV infection rate of HIV positive cases was 94% (35/38. All RPR results were negative. Duration of previous drug abuse and imprisonment were correlated with HIV and HCV infection (p value = 0.0003 and 0.015 & p value =0.02 and 0.02. Considering the higher prevalence of HIV and HCV infection in correctional facilities compared to general population of Iran, warrants immediate multidisciplinary approaches targeted at controlling further spread of these infections primarily among prisoners and secondarily preventing them to act as carrier to general population.

    Cryptococcus neoformans is an encapsulated fungal pathogen that is remarkable for its tendency to cause meningoencephalitis, especially in patients with AIDS. While disease is less common in children than adults, it remains an important cause of morbidity and mortality among HIV-infected children without access to anti-retroviral therapy. This review highlights recent insights into both the biology and treatment of cryptococcosis with a special emphasis on the pediatric literature. PMID:27443557

    The magnitude of intestinal parasitic infection in acquired immunodeficiency syndrome patients requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several tropical diseases. However, there have been very few studies addressing this issue in Cameroon. This study was conducted to determine the prevalence of intestinal parasitosis in HIV/AIDS patients in Dschang -Cameroon. Stool and blood specimens from HIV/AIDS patients and control group were screened respectively for intestinal parasites and for HIV antibodies. Intestinal parasites were identified using direct microscopy, formalin-ether concentration and Ziehl Neelsen methods. Out of 396 participants recruited among patients consulting at hospital, 42 (10.6%) were HIV positive, thirty of them treatment naïve. The overall prevalence of intestinal parasites was 14.64%. Out of 42 HIV/AIDS patients, 59.5% (25/42) were infected with intestinal parasites, while only 9.32% (33/354) of the HIV negative patients were infected with intestinal parasites. The parasites detected in our study population included Crystosporidium parvum (2.53%), Entamoeba histolytica (7.52%), Entamoeba coli (4.04%), Giardia lamblia (0.25%), Trichuris trichura (0.25%), Strongyloides stercoralis (0.25%) and Taenia spp. (0.25%). In the HIV infected group, Crystosporidium parvum (19.04%), Entamoeba histolytica (19.04%), Entamoeba coli (21.42%), Giardia lamblia (2.38%), Strongyloides stercoralis (0.25%) and Taenia spp. (0.25%) were found. Crystosporidium parvum was found to be significantly higher in HIV/AIDS patients than in controls (Pintestinal parasitosis. Routine examinations of stool samples for parasites would significantly benefit the HIV patients by contributing in reducing morbidity and improving the efficiency of antiretroviral treatment. Even after the introduction of free anti-retroviral drugs, opportunistic intestinal infections are still a threat. HIV patients should be screened

    HIV-1 infection to the central nervous system (CNS) is very common in AIDS patients. The predominant cell types infected in the brain are monocytes and macrophages, which are surrounded by several HIV-1-resistant cell types, such as astrocytes, oligodendrocytes, neurons, and microvascular cells. The effect of these HIV-1-resistant cells on HIV-1 infection is largely unknown. In this study, we examined the stability of HIV-1 cultured with several human glioblastoma cell lines, for example, NP-2, U87MG, T98G, and A172, to determine whether these HIV-1-resistant brain cells could enhance or suppress HIV-1 infection and thus modulate HIV-1 infection in the CNS. The HIV-1 titer was determined using the MAGIC-5A indicator cell line as well as naturally occurring CD4(+) T cells. We found that the stability of HIV-1 incubated with NP-2 or U87MG cells at 37°C was significantly shorter (half-life, 2.5-4 h) compared to that of HIV-1 incubated with T98G or A172 cells or in culture medium without cells (half-life, 8-18 h). The spent culture media (SCM) of NP-2 and U87MG cells had the ability to suppress both R5- and X4-HIV-1 infection by inhibiting HIV-1 attachment to target cells. This inhibitory effect was eliminated by the treatment of the SCM with chondroitinase ABC but not heparinase, suggesting that the inhibitory factor(s) secreted by NP-2 and U87MG cells was chiefly mediated by chondroitin sulfate (CS) or CS-like moiety. Thus, this study reveals that some but not all glioma cells secrete inhibitory molecules to HIV-1 infection that may contribute in lowering HIV-1 infection in the CNS in vivo.

    South Africa is experiencing a growing methamphetamine problem, and there is concern that methamphetamine use may accelerate HIV transmission. There has been little research on the HIV prevention needs of methamphetamine users receiving substance abuse treatment in South Africa. This study assessed the prevalence and correlates of HIV risk behaviors among 269 methamphetamine users entering substance abuse treatment in two clinics in Cape Town. The prevalence of sexual risk behaviors was high among sexually active participants: 34 % multiple partners, 26 % unprotected intercourse with a casual partner, and 24 % sex trading for money/methamphetamine. The strongest predictor of all sexual risk behaviors was concurrent other drug use. Over half had not been HIV tested in the past year, and 25 % had never been tested, although attitudes toward HIV testing were overwhelmingly positive. This population of primarily heterosexual, non-injecting methamphetamine users is a high-risk group in need of targeted HIV prevention interventions. Substance abuse treatment is an ideal setting in which to reach methamphetamine users for HIV services.

The aim of the study was to assess neurocognitive profiles of newly detected HIV-infected patients. We performed an observational retrospective single-cohort study. Illiterates and patients with neurologic symptoms or previous psychiatric diagnosis were excluded. Neuropsychological profiles were assessed using a validated battery of neuropsychological tests. We included 206 patients; with males representing the majority of them (85%. Risk factors for HIV acquisition were unprotected sexual intercourse (homo/bisexual in 39.8% and heterosexual in 60.2%. Thirty-nine patients (18.9% were previous injection drug users, while 41 (19.9% were alcohol abusers. Mean education was 11.1 years (SD—standard deviation—3.7. A high prevalence of HIV-associated neurocognitive disorders (HAND, 47.1% was present in HIV-infected patients: particularly, asymptomatic neurocognitive impairment (ANI was found in 30.6%, mild neurocognitive disorder (MND in 15% and HIV-associated dementia (HAD in 1.5%. Male gender, low degree of education, AIDS diagnosis and gepatitis B virus (HBV co-infection were factors independently associated with HAND in a multivariable logistic regression model. Our data suggest that patient-specific factors and AIDS diagnosis have a certain kind of impact in HAND occurrence. A complete neuropsychological screening must be recommended in all patients at HIV-infection diagnosis.

    Vertically transmitted HIV infection is a major problem in the developing world due to the poor availability of antiretroviral agents to pregnant women. HIV is a neurotrophic virus and causes devastating neurological insults to the immature brain. The effects of the virus are further compounded by the opportunistic infections and neoplasms that occur as a result of the associated immune suppression. This review focuses on the imaging features of HIV infection and its complications in the central nervous system. (orig.)

Our aim is to analyse the prevalence and features of lung cancer in HIV-infected patients. Methods: The clinical charts of 4,721 HIV-infected patients seen in three hospitals of southeast Spain (study period 1992–2012 were reviewed, and all patients with a lung cancer were analysed. Results: There were 61 lung cancers, giving a prevalence of 1.2%. There was a predominance of men (82.0%, and smokers (96.6%; mean pack-years 35.2, with a median age of 48.0 (41.7–52.9 years, and their distribution according to risk group for HIV was: intravenous drug use 58.3%, homosexual 20.0%, and heterosexual 16.7%. Thirty-four (56.7% patients were Aids cases, and 29 (47.5% had prior pulmonar events: tuberculosis 16, bacterial pneumonia 9, and P. jiroveci pneumonia 4. The median nadir CD4 count was 149/mm3 (42–232, the median CD4 count at the time of diagnosis of the lung cancer was 237/mm3 (85–397, and 66.1%<350/mm3. 66.7% were on ART, and 70% of them had undetectable HIV viral load. The most common histological types of lung cancer were adenocarcinoma and epidermoid, with 24 (40.0% and 23 (38.3% cases, respectively. There were 49 (80.3% cases with advanced stages (III and IV at diagnosis. The distribution of treatments was: only palliative 23 (39.7%, chemotherapy 14 (24.1%, surgery and chemotherapy 8 (13.8%, radiotherapy 7 (12.1%, surgery 4 (6.9%, and other combined treatments 2 (3.4%. Forty-six (76.7% patients died, with a median survival time of 3 months. The Kaplan-Meier survival rate at 6 months was 42.7% (at 12 months 28.5%. Conclusions: The prevalence of lung cancer in this cohort of HIV-patients is high. People affected are mainly men, smokers, with transmission of HIV by intravenous drug use, and around half of them with prior opportunistic pulmonary events.

    The course of disease among HIV-2, HIV-1, and HIV-1/2 dually infected patients is different. We investigated the macrophage activation marker soluble CD163 (sCD163) dynamics in 212 HIV-1, HIV-2, and HIV-1/2 dually infected patients. There were no differences in sCD163 levels at baseline or during follow-up without antiretroviral therapy (ART). At follow-up on ART, median sCD163 levels were decreased for HIV-1-infected patients (P < 0.001), but not among HIV-2 (P = 0.093) or HIV-1/2 dually infected patients (P = 0.145). The larger decrease in sCD163 levels among HIV-1-infected patients during ART may indicate an HIV type-dependent differential effect of ART on macrophage activation during HIV infection.

    Arendt, Gabriele

    2006-01-01

    At the beginning of the AIDS pandemic, affective disorders (such as depressed mood) were seen in a considerable number of HIV-1-infected individuals. These disorders were a result of the poor physical condition of the patients, brain involvement by the virus (e.g. encephalopathy) or a reaction to disadvantageous living conditions (losing friends, jobs, etc.). In the era of highly active antiretroviral therapy (HAART), mental illness related to physical weakness is declining, as is the incidence of HIV-1-associated encephalopathy. However, depressed mood and fatigue caused by efavirenz (a standard component of HAART) is becoming increasingly important, particularly in individuals who are infected long-term with HIV-1. Whatever the cause of affective disorders, their presence has been shown to negatively influence adherence to HAART and HIV-1 disease progression. Specialist knowledge of HIV-1 infection, and HAART and its psychiatric complications (particularly in subgroups of patients such as drug abusers and older people), is needed to care adequately for patients. Furthermore, prospective studies are needed to more fully differentiate between the various aetiologies of affective disorders seen in individuals living with HIV/AIDS and to determine their incidence and prevalence. Such information is important to ensure that affective disorders are recognised and adequately treated, which will in turn improve the efficacy of HAART. PMID:16734500

    Full Text Available The article reports our intervention work with Alcohol and Other Drug Abusing (AOD People Living With HIV (PLWH. Present research has involved adapting Cognitive Behavioral Stress Management (CBSM and other strategies to improve quality of life and health outcomes for PLWH. Historically, CBSM has used relaxation and coping skills training to reduce negative mood and improve coping behaviors. The efficacy of CBSM interventions to improve functioning has been demonstrated in many disease groups and, more recently, in ethnic-minority HIV+ samples in the US CBSM HIV risk reduction interventions are similar to other cognitive-behavioral therapies in emphasizing skills training and stress reduction. Among the most precarious and challenging clinical populations are HIV infected individuals with a history of alcohol and/or drug abuse. Compared to their counterparts with no history of alcohol or drug abuse, not only are they more likely to transmit the virus to others, but they are also at risk for problems in adhering to antiretroviral regimens. A main focus of this article is to report on our intervention work with very resource-limited, ethnic-minority PLWH with substance abuse problems, particularly our NIH funded projects in Miami and Haiti and the opportunities presented by the emerging science of biological vulnerability and genomic factors.

    Drug addicts have, in general, a less complicated course of HIV infection than homosexual HIV patients. They show fewer opportunistic infections and tumors. But this advantage is lost by unnecessary complications due to their psychic disorders. Their non-compliance and concealment of signs of disease lead to worse outcomes of infections, which could be well-treated or prevented. PMID:8300042

    This study is first of its kind in Bangkok, and is a five-year (2009-2013) cross-sectional web-based survey to examine HIV preventive behaviors related to substance abuse among adolescents (N = 16,913). The questionnaire was self-administered. Logistic regression was used to analyze the data. The relationship between different types of substance abuse with risky and preventive behaviors was assessed. Male participants reported more substance abuse as compared to females. The risk behaviors observed among the substance abusers include increased sexual experience, multiple sex partners, no use of condoms, and injection drug use. The preventive behaviors include having a high self-risk assessment, going for HIV testing (highest in methamphetamine users), and screening for sexually transmitted infection. Logistic regression suggests that risky behaviors (e.g., sexual experience, injection drug use) are more common in substance abusers. Adolescents are clearly at a high risk. Behavioral preventive measures are needed to reduce or delay premature substance exposure to prevent a wide range of health problems and risks such as HIV and AIDS, injection drug use and unprotected sex.

    Full Text Available Abstract Background Concurrent sexually transmitted infections (STIs increase the likelihood of HIV transmission. The levels of defensins are frequently elevated in genital fluids from individuals with STIs. We have previously shown that human defensins 5 and 6 (HD5 and HD6 promote HIV entry and contribute to Neisseria gonorrhoeae-mediated enhancement of HIV infectivity in vitro. In this study, we dissect the molecular mechanism of the HIV enhancing effect of defensins. Results HD5 and HD6 primarily acted on the virion to promote HIV infection. Both HD5 and HD6 antagonized the anti-HIV activities of inhibitors of HIV entry (TAK 779 and fusion (T-20 when the inhibitors were present only during viral attachment; however, when these inhibitors were added back during viral infection they overrode the HIV enhancing effect of defensins. HD5 and HD6 enhanced HIV infectivity by promoting HIV attachment to target cells. Studies using fluorescent HIV containing Vpr-GFP indicated that these defensins enhanced HIV attachment by concentrating virus particles on the target cells. HD5 and HD6 blocked anti-HIV activities of soluble glycosaminoglycans including heparin, chondroitin sulfate, and dextran sulfate. However, heparin, at a high concentration, diminished the HIV enhancing effect of HD5, but not HD6. Additionally, the degree of the HIV enhancing effect of HD5, but not HD6, was increased in heparinase-treated cells. These results suggest that HD5 and haparin/heparan sulfate compete for binding to HIV. Conclusions HD5 and HD6 increased HIV infectivity by concentrating virus on the target cells. These defensins may have a negative effect on the efficacy of microbicides, especially in the setting of STIs.

    The advent of combination antiretroviral drug regimens has transformed HIV infection from a fatal illness into a manageable chronic condition. All patients with HIV infection should be considered for antiretroviral therapy, regardless of CD4 count or HIV viral load, for individual benefit and to prevent HIV transmission. Antiretroviral drugs affect HIV in several ways: entry inhibitors block HIV entry into CD4 T cells; nucleotide and nucleoside reverse transcriptase inhibitors prevent reverse transcription from RNA to DNA via chain-terminating proteins; nonnucleoside reverse transcriptase inhibitors prevent reverse transcription through enzymatic inhibition; integrase strand transfer inhibitors block integration of viral DNA into cellular DNA; protease inhibitors block maturation and production of the virus. Current guidelines recommend six combination regimens for initial therapy. Five are based on tenofovir and emtricitabine; the other uses abacavir and lamivudine. Five include integrase strand transfer inhibitors. HIV specialists should assist with treating patients with complicated HIV infection, including patients with treatment-resistant HIV infection, coinfection with hepatitis B or C virus, pregnancy, childhood infections, severe opportunistic infections, complex drug interactions, significant drug toxicity, or comorbidities. Family physicians can treat most patients with HIV infection effectively by choosing appropriate treatment regimens, monitoring patients closely, and retaining patients in care. PMID:27092564

    In order to determine the prevalence of HIV infection in french patients with end-stage renal disease (ESRD) on maintenance dialysis therapy, questionnaire forms were mailed out in february 1997 to the heads of the 260 dialysis facilities. We documented number of patients on maintenance dialysis therapy (hemo and peritoneal dialysis) and for HIV infected dialysis patients: age, gender, cause and duration of ESRD, known duration of HIV infection, risk factors for HIV infection, HBV and/or HCV infection, presence of clinical acquired immunodeficiency syndrome (AIDS), total CD4 count and treatment with antiretroviral agents. Questionnaire forms were returned from 98% of the dialysis facilities. As of february 1997 some 22,707 patients with ESRD were treated by renal replacement therapy, 19,947 by hemodialysis (HD) and 2760 by peritoneal dialysis (PD). 82 patients with ESRD and HIV infection were reported corresponding to 0.36% prevalence rate of all patients undergoing dialysis at the time specified. The 82 study subjects with ESRD and HIV infection received hemodialysis (79 patients) or peritoneal dialysis (3 patients) in 42 facilities. Forty seven patients were treated in Paris and suburbs and 9 in our own center. All 82 patients comprised 63% men and 47% women which included patients coming from Africa (37%), Caribbean and Oceania (28%), Europe (35%) of a mean age of 41.8 years. Modes of transmission were homobisexuals 15%, heterosexuals 31%, intravenous drug abusers 17%, blood transfusion 17% and unknown 20%. The mean duration of HIV infection was 96 months (range 12-168 months) and the mean duration of ESRD was 58 months (range 1-235 months). HIV associated nephropathy was established in 31%. AIDS was diagnosed in 25 patients. Seventy one percent of the patients were receiving an antiretroviral drug (tritherapy in 25% of cases). In conclusion HIV prevalence rate among French dialysis patients is low and focused in Paris and oversea. Sexual transmission is the

    Full Text Available Human immunodeficiency virus (HIV-1 causes a chronic infection that afflicts more than 38 million individuals worldwide. While the infection can be suppressed with potent anti-retroviral therapies, individuals infected with HIV have elevated levels of inflammation as indicated by increased T cell activation, soluble biomarkers, and associated morbidity and mortality. A single mechanism linking HIV pathogenesis to this inflammation has yet to be identified. Purinergic receptors are known to mediate inflammation and have been shown to be required for HIV-1 infection at the level of HIV-1 membrane fusion. Here we review the literature on the role of purinergic receptors in HIV-1 infection and associated inflammation and describe a role for these receptors as potential therapeutic targets.

    In sub-Saharan Africa, the prevalence of stigma-related abuse and violence among men who have sex with men (MSM) and its potential impact on the HIV/AIDS epidemic is unknown. This study estimated the prevalence and source of violence and abuse among a sample of MSM in Tanzania and characterized the association between levels of violence and sexual and mental health variables. Data were taken from a larger study of 200 MSM in Tanzania. Frequency tabulations, bivariate analysis and logistic regression were performed to describe the prevalence and source of abuse and to determine the association between levels of violence and sexual demographics and mental health variables. The MSM sample for this study was young (median age 23), somewhat educated with the majority having attained secondary school (80%) and mostly employed (60%). Verbal (48.5%) and moral (32.5%) abuse were the most predominant types of abuse among the sample and were mostly from people in the street and neighbors. Sexual abuse (30%) was mostly from partners and physical violence (29.5%) was largely from people in the street. Participants in the high violence level group had a significantly greater number of sexual partners, depression scores and internalized homonegativity (IH) scores. IH predicted HIV infection, and verbal abuse predicted IH. There is a need for an increased awareness of violence and abuse faced by MSM in Tanzania, as well as effective programs to specifically target the issue of violence among MSM and its implication for mental health and for risky sexual behaviors and HIV transmission.

    Full Text Available Abstract Background Children born to HIV+ mothers are exposed intra-utero to several drugs and cytokines that can modify the developing immune system, and influence the newborn's immune response to infections and vaccines. We analyzed the relation between the distribution of cord blood lymphocyte subsets and cytokine profile in term newborns of HIV+ mothers using HAART during pregnancy and compared them to normal newborns. Methods In a prospective, controlled study, 36 mother-child pairs from HIV+ mothers and 15 HIV-uninfected mothers were studied. Hematological features and cytokine profiles of mothers at 35 weeks of pregnancy were examined. Maternal and cord lymphocyte subsets as well as B-cell maturation in cord blood were analyzed by flow cytometry. The non-stimulated, as well as BCG- and PHA-stimulated production of IL2, IL4, IL7, IL10, IL12, IFN-γ and TNF-alpha in mononuclear cell cultures from mothers and infants were quantified using ELISA. Results After one year follow-up none of the exposed infants became seropositive for HIV. An increase in B lymphocytes, especially the CD19/CD5+ ones, was observed in cord blood of HIV-exposed newborns. Children of HIV+ hard drug using mothers had also an increase of immature B-cells. Cord blood mononuclear cells of HIV-exposed newborns produced less IL-4 and IL-7 and more IL-10 and IFN-γ in culture than those of uninfected mothers. Cytokine values in supernatants were similar in infants and their mothers except for IFN-γ and TNF-alpha that were higher in HIV+ mothers, especially in drug abusing ones. Cord blood CD19/CD5+ lymphocytes showed a positive correlation with cord IL-7 and IL-10. A higher maternal age and smoking was associated with a decrease of cord blood CD4+ cells. Conclusions in uninfected infants born to HIV+ women, several immunological abnormalities were found, related to the residual maternal immune changes induced by the HIV infection and those associated with antiretroviral

    Full Text Available BACKGROUND: The prevalence and factors associated with overweight/obesity among human immunodeficiency virus (HIV-infected persons are unknown. METHODS: We evaluated prospective data from a U.S. Military HIV Natural History Study (1985-2004 consisting of early diagnosed patients. Statistics included multivariate linear regression and longitudinal linear mixed effects models. RESULTS: Of 1682 patients, 2% were underweight, 37% were overweight, and 9% were obese at HIV diagnosis. Multivariate predictors of a higher body mass index (BMI at diagnosis included more recent year of HIV diagnosis, older age, African American race, and earlier HIV stage (all p<0.05. The majority of patients (62% gained weight during HIV infection. Multivariate factors associated with a greater increase in BMI during HIV infection included more recent year of diagnosis, lower BMI at diagnosis, higher CD4 count, lower HIV RNA level, lack of AIDS diagnosis, and longer HIV duration (all p<0.05. Nucleoside agents were associated with less weight gain; other drug classes had no significant impact on weight change in the HAART era. CONCLUSIONS: HIV-infected patients are increasingly overweight/obese at diagnosis and during HIV infection. Weight gain appears to reflect improved health status and mirror trends in the general population. Weight management programs may be important components of HIV care.

    Acute HIV-1 infection of CD4 T cells often results in apoptotic death of infected cells, yet it is unclear what evolutionary advantage this offers to HIV-1. Given the independent observations that acute T cell HIV-1 infection results in (1) NF-kappaB activation, (2) caspase 8 dependent apoptosis, and that (3) caspase 8 directly activates NF-kappaB, we questioned whether these three events might be interrelated. We first show that HIV-1 infected T cell apoptosis, NF-kappaB activation, and casp...

    Juvenile offenders are a subgroup of adolescents at particular risk for HIV/STI infection. Although HIV prevalence among these youth is low (criminal justice system, which is known to have an extremely high rate of HIV infection. US constitutional mandates provide HIV/STI testing for incarcerated juveniles, but close to 80% of juvenile arrestees are never detained. Moreover, although they engage in similar HIV risk behaviors as those detained, they have limited access to available HIV/STI testing services. Thus, our study examined rates of lifetime HIV testing among a pilot sample of 60 court-involved, substance-using juveniles monitored in the community to explore rates of testing and the reasons related to lifetime testing among a high-risk, yet understudied US juvenile population.

    The various neurological complications associated with HIV-1 infection, specifically HIV-associated neurocognitive disorders (HAND) persist as a major public health burden worldwide. Despite the widespread use of anti-retroviral therapy, the prevalence of HAND is significantly high. HAND results from the direct effects of an HIV-1 infection as well as secondary effects of HIV-1-induced immune reaction and inflammatory response. Complement, a critical mediator of innate and acquired immunity, plays important roles in defeating many viral infections by the formation of a lytic pore or indirectly by opsonization and recruitment of phagocytes. While the role of complement in the pathogenesis of HIV-1 infection and HAND has been previously recognized for over 15 years, it has been largely underestimated thus far. Complement can be activated through HIV-1 envelope proteins, mannose-binding lectins (MBL), and anti-HIV-1 antibodies. Complement not only fights against HIV-1 infection but also enhances HIV-1 infection. In addition, HIV-1 can hijack complement regulators such as CD59 and CD55 and can utilize these regulators and factor H to escape from complement attack. Normally, complement levels in brain are much lower than plasma levels and there is no or little complement deposition in brain cells. Interestingly, local production and deposition of complement are dramatically increased in HIV-1-infected brain, indicating that complement may contribute to the pathogenesis of HAND. Here, we review the current understanding of the role of complement in HIV-1 infection and HAND, as well as potential therapeutic approaches targeting the complement system for the treatment and eradications of HIV-1 infection.

    Few Positive Prevention interventions have been implemented in Africa; however, greater attention is now being paid to interventions that include messages of personal responsibility or altruism that may motivate HIV-infected individuals towards HIV prevention behaviors in Africa. We conducted 47 in-depth interviews in 2004 with HIV-infected men and women purposefully sampled to represent a range of sexual activities among clients of an AIDS support organization in Uganda. Qualitative interviews were selected from a cross-sectional survey of 1092 HIV-infected men and women. Clients were interviewed about their concerns around sexual HIV transmission, feelings of responsibility and reasons for these feelings, as well as about the challenges and consequences of actions to prevent HIV transmission. The reasons they provided for their sense of prevention responsibility revolved around ethical and practical themes. Responsibility toward sexual partners was linked to the belief that conscious transmission of HIV equals murder, would cause physical and emotional harm, and would leave children orphaned. The primary reason specific to preventing HIV transmission to unborn children was the perception that they are 'innocent'. Most participants felt that HIV-infected individuals held a greater responsibility for preventing HIV transmission than did HIV-uninfected individuals. Respondents reported that their sense of responsibility lead them to reduce HIV transmission risk, encourage partner testing, disclose HIV test results, and assume an HIV/AIDS educator role. Challenges to HIV preventive behavior and altruistic intentions included: sexual desire; inconsistent condom use, especially in long term relationships; myths around condom use; fear of disclosure; gender-power dynamics; and social and financial pressure. Our finding that altruism played an important role in motivating preventive behaviors among HIV-infected persons in Uganda supports the inclusion of altruistic

    The precise effects of HIV-1 on the gut microbiome are unclear. Initial cross-sectional studies provided contradictory associations between microbial richness and HIV serostatus and suggested shifts from Bacteroides to Prevotella predominance following HIV-1 infection, which have not been found in animal models or in studies matched for HIV-1 transmission groups. In two independent cohorts of HIV-1-infected subjects and HIV-1-negative controls in Barcelona (n = 156) and Stockholm (n = 84), men who have sex with men (MSM) predominantly belonged to the Prevotella-rich enterotype whereas most non-MSM subjects were enriched in Bacteroides, independently of HIV-1 status, and with only a limited contribution of diet effects. Moreover, MSM had a significantly richer and more diverse fecal microbiota than non-MSM individuals. After stratifying for sexual orientation, there was no solid evidence of an HIV-specific dysbiosis. However, HIV-1 infection remained consistently associated with reduced bacterial richness, the lowest bacterial richness being observed in subjects with a virological-immune discordant response to antiretroviral therapy. Our findings indicate that HIV gut microbiome studies must control for HIV risk factors and suggest interventions on gut bacterial richness as possible novel avenues to improve HIV-1-associated immune dysfunction.

However, HIV-1 infection remained consistently associated with reduced bacterial richness, the lowest bacterial richness being observed in subjects with a virological-immune discordant response to antiretroviral therapy. Our findings indicate that HIV gut microbiome studies must control for HIV risk factors and suggest interventions on gut bacterial richness as possible novel avenues to improve HIV-1-associated immune dysfunction.

    While cortical thinning has been associated with HIV infection, it is unclear whether this reflects a direct effect of the virus, whether it is related to disruption of subcortical function or whether it is better explained by epiphenomena, such as drug abuse or comorbid medical conditions. The present study investigated the relationship between cortical thickness and subcortical function in HIV+ patients. Specifically, we examined the relationship between prefrontal cortical thickness and striatal function. Twenty-three largely treatment naïve, non-substance abusing HIV+ participants and 19 healthy controls matched for age, gender, and educational status were included. Cortical morphometry was performed using FreeSurfer software analysis. Striatal function was measured during an fMRI stop-signal anticipation task known to engage the striatum. Any cortical regions showing significant thinning were entered as dependent variables into a single linear regression model which included subcortical function, age, CD4 count, and a measure of global cognitive performance as independent predictors. The only cortical region that was significantly reduced after correction for multiple comparisons was the right superior frontal gyrus. Striatal activity was found to independently predict superior frontal gyral cortical thickness. While cortical thinning in HIV infection is likely multifactorial, viral induced subcortical dysfunction appears to play a role. PMID:27173383

    Full Text Available HIV-infected prisoners in Malaysia represent a critical target population for secondary HIV risk reduction interventions and care. We report on the process and outcome of our formative research aimed at systematically selecting and adapting an EBI designed to reduce secondary HIV risk and improve adherence to antiretroviral therapy among soon-to-be-released HIV-infected prisoners. Our formative work involved a critical examination of established EBIs and associated published reports complemented by data elicited through structured interviews and focus groups with key stakeholders, members of the target population, and their family members. Based on all information, we adapted the Holistic Health Recovery Program targeting people living with HIV (HHRP+, an EBI, to consist of eight 2-hour sessions that cover a range of specified topics so that participants may individually apply intervention content as needed to accommodate their particular substance abuse, HIV risk, and antiretroviral adherence issues. This study provides a complete example of the process of selecting and adapting an EBI—taking into account both empirical evidence and input from target organization stakeholders and target population members and their families—for use in real world prison settings where high-risk populations are concentrated.

    1995-07-01

    Human immunodeficiency virus (HIV) infection is characterised by seroconversion after a ¿window¿ period of 2 to 3 months. After this period antibodies are usually detectable by screening tests (enzyme immunoassay or particle agglutination) confirmed by Western blot analysis. We studied 1000 newly enrolled female sex workers who had not been previously tested for HIV to assess the usefulness of HIV antigen testing to improve the efficacy of HIV infection detection. Blood was taken at enrollment for HIV antigen and HIV antibody testing. The Abbott HIVAG-1 test was used to detect antigen; antibody detection was by the Abbott recombinant HIV-1/HIV-2 3rd generation enzyme immunoassay (EIA) test, the Fujirebio Serodia-HIV particle agglutination (PA) test for screening, and the Diagnostic Biotechnology HIV Blot 2.2 Western blot (WB) test for antibody confirmation. Of the 1000 samples, 26 were positive for HIV antibody testing (26/26 for EIA, 25/25 for PA, 26/26 for WB), giving a prevalence rate of 2.6%, Of these 26 seropositive samples 1 was positive on HIV antigen testing. There were no samples which were antigen-positive and antibody-negative. HIV antigen testing does not add to increased efficacy of HIV detection among female sex workers in Singapore.

    2008-09-01

    In this review we summarize the data on interaction of platelets with HIV-1 infection. Thrombocytopenia is a common finding among HIV-1 infected patients; several combined factors contribute to low peripheral platelet counts, which are present during all the stages of the disease. In addition, a relationship between platelet count, plasma viral load and disease progression has been reported, and this shows the potential influence platelets may have on the natural history of HIV-1 disease. Several lines of evidence have shown that platelets are an integral part of inflammation, and can be also potent effector cells of innate immune response as well as of adaptive immunity. Thus, we rewieved the role of inflammatory cytokines, and chemokines as activators of platelets during HIV-1 infection. Moreover, platelets show a direct interaction with HIV-1 itself, through different pathogenic mechanisms as binding, engulfment, internalisation of HIV-1, playing a role in host defence during HIV-1 infection, by limiting viral spread and probably by inactivating viral particles. Platelets may also play an intriguing role on endothelial dysfunction present in HIV-1 infection, and this topic begins to receive systematic study, inasmuch as interaction between platelets and endothelial cells is important in the pathogenesis of atherosclerosis in HIV-1 infected patients, especially in those patients treated with antiretroviral drugs. Finally, this review attempts to better define the state of this emerging issue, to focus areas of potential clinical relevance, and to suggest several directions for future research.

    Full Text Available Risky decision-making is commonly observed in persons at risk for and infected with HIV and is associated with executive dysfunction. Yet it is currently unknown whether HIV alters brain processing of risk-taking decision-making.This study examined the neural substrate of a risky decision-making task in 21 HIV seropositive (HIV+ and 19 seronegative (HIV- comparison participants. Functional magnetic resonance imaging was conducted while participants performed the risky-gains task, which involves choosing among safe (20 cents and risky (40/80 cent win or loss choices. Linear mixed effects analyses examining group and decision type were conducted. Robust regressions were performed to examine the relationship between nadir CD4 count and Kalichman sexual compulsivity and brain activation in the HIV+ group. The overlap between the task effects and robust regressions was explored.Although there were no serostatus effects in behavioral performance on the risky-gains task, HIV+ individuals exhibited greater activation for risky choices in the basal ganglia, i.e. the caudate nucleus, but also in the anterior cingulate, dorsolateral prefrontal cortex, and insula relative to the HIV- group. The HIV+ group also demonstrated reduced functional responses to safe choices in the anterior cingulate and dorsolateral prefrontal cortex relative to the HIV- group. HIV+ individuals with higher nadir CD4 count and greater sexual compulsivity displayed lower differential responses to safe versus risky choices in many of these regions.This study demonstrated fronto-striatal loop dysfunction associated with HIV infection during risky decision-making. Combined with similar between-group task behavior, this suggests an adaptive functional response in regions critical to reward and behavioral control in the HIV+ group. HIV-infected individuals with higher CD4 nadirs demonstrated activation patterns more similar to seronegative individuals. This suggests that the severity of

    Not everyone exposed to an efficacious human immunodeficiency virus (HIV) intervention will reduce sexual risk behaviors, yet little is known about factors associated with "failure to change" high-risk sexual behaviors post-intervention. History of abuse and polymorphisms in the serotonin transporter gene (5-HTT) may be associated with non-change. The current study sought to identify genetic, life history, and psychosocial factors associated with adolescents' failure to change condom use behaviors post-participation in an HIV prevention intervention. A sub-set of participants from a clinic-based sample of adolescent African-American females (N = 254) enrolled in a randomized trial of an HIV-prevention was utilized for the current study. Forty-four percent did not increase their condom use from baseline levels 6 months after participating in the sexually transmitted infection (STI)/HIV prevention intervention. In multivariable logistic regression analysis, an interaction between abuse and 5-HTTLPR group was significantly associated with non-change status, along with partner communication frequency scores at follow-up. Follow-up tests found that having a history of abuse was significantly associated with greater odds of non-change in condom use post-intervention for only those with the s allele. For those with ll allele, participants with higher partner communication frequency scores were at decreased odds of non-change in condom use post-intervention. Thus, STI/HIV interventions for adolescent females may consider providing a more in-depth discussion and instruction on how to manage and overcome fear or anxiety related to being assertive in sexual decisions or sexual situations. Doing so may improve the efficacy of STI/HIV prevention programs for adolescent women who have experienced abuse in their lifetime. PMID:23479192

    Full Text Available The magnitude of intestinal parasitic infection in acquired immunodeficiency syndrome patients requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several tropical diseases. However, there have been very few studies addressing this issue in Cameroon. This study was conducted to determine the prevalence of intestinal parasitosis in HIV/AIDS patients in Dschang -Cameroon. Stool and blood specimens from HIV/AIDS patients and control group were screened respectively for intestinal parasites and for HIV antibodies. Intestinal parasites were identified using direct microscopy, formalin-ether concentration and Ziehl Neelsen methods. Out of 396 participants recruited among patients consulting at hospital, 42 (10.6% were HIV positive, thirty of them treatment naïve. The overall prevalence of intestinal parasites was 14.64%. Out of 42 HIV/AIDS patients, 59.5% (25/42 were infected with intestinal parasites, while only 9.32% (33/354 of the HIV negative patients were infected with intestinal parasites. The parasites detected in our study population included Crystosporidium parvum (2.53%, Entamoeba histolytica (7.52%, Entamoeba coli (4.04%, Giardia lamblia (0.25%, Trichuris trichura (0.25%, Strongyloides stercoralis (0.25% and Taenia spp. (0.25%. In the HIV infected group, Crystosporidium parvum (19.04%, Entamoeba histolytica (19.04%, Entamoeba coli (21.42%, Giardia lamblia (2.38%, Strongyloides stercoralis (0.25% and Taenia spp. (0.25% were found. Crystosporidium parvum was found to be significantly higher in HIV/AIDS patients than in controls (P<0.05. Multivariate analysis showed that the HIV status and the quality of water were the major risk factors for intestinal parasitosis. Routine examinations of stool samples for parasites would significantly benefit the HIV patients by contributing in reducing morbidity and improving the efficiency of antiretroviral treatment.

    Hepatitis E virus (HEV) is a RNA virus that can cause hepatitis. In immunocompetent individuals, infection with HEV usually leads to asymptomatic seroconversion. However, in immunosuppressed patients, such as transplant recipients, HEV can develop into a chronic infection. Studies regarding the seroprevalence and clinical implications of HEV in patients infected with the human immunodeficiency virus (HIV) are conflicting. Levels of CD4 count in blood seem to be the most widely associated risk factor, while other factors such as meat consumption or proximity to animals are less clearly associated with HEV infection. Progression to chronicity, as well as extrahepatic manifestations of HEV seem rare in HIV, and the implications of HEV in liver disease progression are poorly understood in the HIV-infected. In this review we describe the epidemiology, risk factors, and clinical implications of HEV infection in individuals infected with HIV. PMID:27243210

    Full Text Available Abstract Mathematical models of viral dynamics in vivo provide incredible insights into the mechanisms for the nonlinear interaction between virus and host cell populations, the dynamics of viral drug resistance, and the way to eliminate virus infection from individual patients by drug treatment. The integration of these mathematical models with high-throughput genetic and genomic data within a statistical framework will raise a hope for effective treatment of infections with HIV virus through developing potent antiviral drugs based on individual patients’ genetic makeup. In this opinion article, we will show a conceptual model for mapping and dictating a comprehensive picture of genetic control mechanisms for viral dynamics through incorporating a group of differential equations that quantify the emergent properties of a system.

    In this paper, we review serological and molecular based methods to identify HIV infection recency. The accurate identification of recent HIV infection continues to be an important research area and has implications for HIV prevention and treatment interventions. Longitudinal cohorts that follow HIV negative individuals over time are the current gold standard approach, but they are logistically challenging, time consuming and an expensive enterprise. Methods that utilize cross-sectional testing and biomarker information have become an affordable alternative to the longitudinal approach. These methods use well-characterized biological makers to differentiate between recent and established HIV infections. However, recent results have identified a number of limitations in serological based assays that are sensitive to the variability in immune responses modulated by HIV subtypes, viral load and antiretroviral therapy. Molecular methods that explore the dynamics between the timing of infection and viral evolution are now emerging as a promising approach. The combination of serological and molecular methods may provide a good solution to identify recent HIV infection in cross-sectional data. As part of this review, we present the advantages and limitations of serological and molecular based methods and their potential complementary role for the identification of HIV infection recency.

IV drug abuse, sexual contact, occupational transmission, blood transfusion and maternal-fetal transmission are well known transmission routes for HIV infection. This study was under taken to investigate the prevalence of HIV transmission routs in the HIV infected population of Sirjan, and their knowledge about the disease, in order to plan better preventive strategies. Materials & Methods: A cross sectional study was planned. During a 6-month period in 2010, all of the HIV infected people in Sirjan (old and new cases who had a file at the consultation center for high risk behavior, completed a valid and reliable questionnaire. Results: The definite route of transmission was not clear in any of the patients because they had more than one suspicious route. Injected drug abusers were the most common (88.4% followed by those who got tattoos (79.1%, invasive therapeutic procedures, dentistry, surgery and endoscopy (56.1%, high risk sexual behavior (62.8%, bloodletting (9.3%, injuries in the barbershop (9.3% and blood transfusion (2.3%. Conclusion: All of the HIV infected cases in Sirjan were involved with several high risk behaviors, but the major route of transmission, similar to other parts of the country was injected drug abuse. Educational programs for prevention of AIDS should be followed seriously and special attention should be paid to groups with multiple high risk behaviors.

    @@ The natural historv of HIV is defined as the untreated progression from the time of HIV transmission to death.1 The typical course of infection is characterized by three phases: acute or primary infection phase, the asymptomatic phase, and AIDS. Primary infection is often accompanied by a symptomatic acute retroviral syndrome starting 2-3 weeks after transmission and lasting an additional 2-4 weeks.1,2

    Increased life expectancy and the need for long-term antiretroviral therapy have brought new challenges to the clinical management of HIV-infected individuals. The prevalence of osteoporosis and fractures is increased in HIV-infected patients; thus optimal strategies for risk management and treatment in this group of patients need to be defined. Prevention of bone loss is an important component of HIV care as the HIV population grows older. Understanding the mechanisms by which HIV infection...

    Abstract: The P24 antigen test, HIV RNA PCR test,HIV isolation/culture and fourth-generation HIV uniform Ag/Ab assay are being utilized in diagnosing acute HIV infection in different labs. Many factors limit the use of screening for acute HIV in high-risk populations, in blood donors and during voluntary HIV testing, including, cost, technique, sensitivity and specificity. In this review we explore a new NAAT method which involves HIV RNA RT-PCR on pooled samples. This technique is able to screen for acute infections in a large testing volume and may he used as a screening method in high-risk populations and blood donors.

  1. Minimizing the risk of non-vertical, non-sexual HIV infection in children – beyond mother to child transmission

    Full Text Available After witnessing an episode of poor injection safety in large numbers of children in a rural under-resourced hospital in Uganda, we briefly review our own experience and that of others in investigating HIV infection in children considered unlikely to be through commonly identified routes such as vertical transmission, sexual abuse or blood transfusion. In the majority of cases, parents are HIV uninfected. The cumulative experience suggests that the problem is real, but with relatively low frequency. Vertical transmission is the major route for HIV to children. However, factors such as poor injection safety, undocumented surrogate breast feeding, an HIV-infected adult feeding premasticated food to a weaning toddler, poor hygienic practice in the home and using unsterilised equipment for minor surgical or traditional procedures are of cumulative concern.

    Exosomes are small membrane-bound vesicles secreted by cells that function to shuttle RNA and proteins between cells. To examine the role of exosomal micro RNA (miRNA) during the early stage of HIV-1 infection we characterized miRNA in exosomes from HIV-infected macrophages, compared with exosomes from non-infected macrophages. Primary human monocytes from uninfected donors were differentiated to macrophages (MDM) which were either mock-infected or infected with the macrophage-tropic HIV-1 BaL strain. Exosomes were recovered from culture media and separated from virus particles by centrifugation on iodixanol density gradients. The low molecular weight RNA fraction was prepared from purified exosomes. After pre-amplification, RNA was hybridized to microarrays containing probes for 1200 miRNA species of known and unknown function. We observed 48 miRNA species in both infected and uninfected MDM exosomes. Additionally, 38 miRNAs were present in infected-cell exosomes but not uninfected-cell exosomes. Of these, 13 miRNAs were upregulated in exosomes from HIV-infected cells, including 4 miRNA species that were increased by more than 10-fold. Though numerous miRNA species have been identified in HIV-infected cells, relatively little is known about miRNA content in exosomes from these cells. In the future, we plan to investigate whether the upregulated miRNA species we identified are increased in exosomes from HIV-1-positive patients.

  4. The Diagnosis of HIV Infection in Infants and Children.

    It is estimated that the number of HIV infected children globally has increased from 1.6 million in 2001 to 3.3 million in 2012. The number of children below 15 years of age living with HIV has increased worldwide. Published data from recent studies confirmed dramatic survival benefit for infants started anti-retroviral therapy (ART) as early as possible after diagnosis of HI. Early confirmation of HIV diagnosis is required in order to identify infants who need immediate ART. WHO has designed recommendations to improve programs for both early diagnoses of HIV infection and considering ART whenever indicated? It is strongly recommended that HIV virologocal assays for diagnosis of HIV have sensitivity of at least 95% and ideally greater than 98% and specificity of 98% or more under standardized and validated conditions. Timing of virological testing is also important. Infants infected at or around delivery may take short time to have detectable virus. Therefore, sensitivity of virological tests is lower at birth. In utero HIV infection, HIV DNA or RNA can be detected within 48 h of birth and in infants with peripartum acquisition it needs one to two weeks. Finally it is emphasized that all laboratories performing HIV tests should follow available services provided by WHO or CDC for quality assurance programs. Both clinicians and staffs providing laboratory services need regular communications, well-defined SOPs and nationally validated algorithms for optimal use of laboratory tests. Every country should use assays that have been validated by national reference laboratory. PMID:27499768

    Human papillomavirus (HPV) causes the majority of oropharyngeal cancers in the United States, yet the risk factors for and natural history of oral HPV infection are largely unknown. In 2010–2011, a US-based longitudinal cohort study of 761 human immunodeficiency virus (HIV)-infected and 469 at-risk HIV-uninfected participants from the Multicenter AIDS Cohort Study and the Women's Interagency HIV Study was initiated. Semiannually collected oral rinses were evaluated for 37 HPV genotypes using the Roche LINEAR ARRAY HPV Genotyping Test (Roche Molecular Systems, Pleasanton, California), and factors associated with oral HPV incidence and clearance were explored using adjusted Wei-Lin-Weissfeld modeling. Through 2013, the 2-year cumulative incidence of any type of oral HPV infection was 34% in HIV-infected persons and 19% in HIV-uninfected persons. However, many of these infections cleared. Seven percent of incident infections and 35% of prevalent infections persisted for at least 2 years. After adjustment for other risk factors, HIV infection (adjusted hazard ratio = 2.3, 95% confidence interval: 1.7, 3.2), reduced current CD4 cell count, and increased numbers of oral sex and “rimming” partners increased the risk of incident oral HPV infection, whereas male sex, older age, and current smoking increased the risk of oral HPV persistence (each P < 0.05). This helps explain the consistent associations observed between these factors and prevalent oral HPV infection in previous cross-sectional studies. PMID:25480823

    Infection by some viruses induces immunity to reinfection, providing a means to identify protective epitopes. To investigate resistance to reinfection in an animal model of HIV disease and its control, we employed infection of mice with chimeric HIV, EcoHIV. When immunocompetent mice were infected by intraperitoneal (IP) injection of EcoHIV, they resisted subsequent secondary infection by IP injection, consistent with a systemic antiviral immune response. To investigate the potential role of these responses in restricting neurotropic HIV infection, we established a protocol for efficient EcoHIV expression in the brain following intracranial (IC) inoculation of virus. When mice were inoculated by IP injection and secondarily by IC injection, they also controlled EcoHIV replication in the brain. To investigate their role in EcoHIV antiviral responses, CD8+ T lymphocytes were isolated from spleens of EcoHIV infected and uninfected mice and adoptively transferred to isogenic recipients. Recipients of EcoHIV primed CD8+ cells resisted subsequent EcoHIV infection compared to recipients of cells from uninfected donors. CD8+ spleen cells from EcoHIV-infected mice also mounted modest but significant interferon-γ responses to two HIV Gag peptide pools. These findings suggest EcoHIV-infected mice may serve as a useful system to investigate the induction of anti-HIV protective immunity for eventual translation to human beings.

    We investigated human rights concerns related to migration, living and working conditions, and access to HIV/AIDS services and reproductive health services for Burmese women in Thailand. Vulnerability to HIV/AIDS for Burmese women stemmed from abuses they experienced: gender and ethnic discrimination, including violence; unsafe migration and trafficking; labor and sexual exploitation; and denial of health care. Despite having bound itself to human rights laws, the Thai government is failing to fulfill its obligations to Burmese women, with particularly devastating impacts for their well-being, including the risk of HIV/AIDS. Moreover, as our documentation shows, this failure to incorporate human rights concerns into its national response to the epidemic virtually guarantees that HIV/AIDS will continue to be a problem in Thailand.

    Hispanic females are disproportionately affected by substance abuse, intimate partner violence, and HIV. Despite these disparities, research describing the cultural and gender-specific experiences of Hispanic women with regard to these conditions is lacking. The purpose of this study is to describe the experiences that Hispanic community-dwelling women have with regard to substance abuse, violence, and risky sexual behaviors. Eight focus groups with 81 women were conducted. A bilingual, bicultural moderator asked women open-ended questions regarding the experiences that Hispanic women have with these conditions. Focus groups were audiotaped, transcribed, translated, verified, and then analyzed using qualitative content analysis. Participants discussed substance abuse, violence, and risky sexual behaviors interchangeably, often identifying common risk factors associated with these. Nevertheless, intimate partner violence was the most salient of conditions discussed. Three major themes emerged from the analysis: Transplantadas en otro mundo (Uprooted in another world), El criador de abuso (The breeding ground of abuse), and Rompiendo el silencio (Breaking the silence). This study supports the importance of addressing substance abuse, violence, and risk for HIV in an integrated manner and stresses the importance of addressing associated cultural factors (e.g., acculturation, machismo) in interventions targeting Hispanics.

    Thailand, a popular tourist destination for Norwegians, is experiencing an increasing epidemic of HIV infection. We used the Norwegian surveillance system for communicable diseases to assess the connections between the Norwegian and Thai epidemics. Before 1999, 1,869 cases of HIV-infection had been reported in Norway. From 1993 to 1998, 1,334 cases of gonorrhoea and 62 cases of syphilis were reported. We studied cases with a Thai patient or source partner and cases acquired in Thailand. 56 (3%) of HIV-infection cases, 64 (5%) of gonorrhoea cases and two (3%) of syphilis cases were connected to Thailand. All the Norwegians who acquired HIV in Thailand were males, with a median age of 39. Eight of them were diagnosed in 1998 as compared to 16 during the previous ten-year period. 21 Thai women and seven males were diagnosed with HIV infection in Norway, eight in 1998 and 20 in the previous ten-year period. The Norwegian HIV epidemic is influenced by the Thai epidemic. Norwegian men are infected in Thailand during holidays. Thai women come with their Norwegian partner to Norway and later discover their HIV status. We recommend raising the awareness of the Thai epidemic among Norwegian tourists. Immigrants to Norway from highly endemic countries should be offered HIV counselling and testing. PMID:10592752

    HIV-1-infected mononuclear phagocytes release soluble factors that affect the homeostasis in tissue. HIV-1 can prompt metabolic encephalopathy with the addition of neuronal dysfunction and apoptosis. Recently, we reported that HIV-1 enhances the expression and secretion of bioactive cathepsin B in monocyte-derived macrophages, ultimately contributing to neuronal apoptosis. In this research, we asked if microglia respond to HIV infection similarly by modifying the expression, secretion, and neurotoxic potential of cathepsin B and determined the in vivo relevance of these findings. HIV-1ADA-infected human primary microglia and CHME-5 microglia cell line were assessed for expression and activity of cathepsin B, its inhibitors, cystatins B and C, and the neurotoxicity associated with these changes. Human primary neurons were exposed to supernatants from HIV-infected and uninfected microglia in the presence of cathepsin B inhibitors and apoptosis was assessed by TUNEL. Microglial expression of cathepsin B was validated in brain tissue from HIV encephalitis (HIVE) patients. HIV-infected microglia secreted significantly greater levels of cathepsin B, cystatin B, and cystatin C compared to uninfected cells. Increased apoptosis was observed in neurons exposed to supernatants from HIV-1 infected microglia at day 12 post-infection. The cathepsin B inhibitor CA-074 and cathepsin B antibody prevented neuronal apoptosis. Increased microglia-derived cathepsin B, cystatin B, and cystatin C and caspase-3+ neurons were detected in HIVE brains compared to controls. Our results suggest that HIV-1-induced cathepsin B production in microglia contributes to neuronal apoptosis and may be an important factor in neuronal death associated with HIVE.

    Full Text Available Objective. The purpose of this study was to describe the epidemiology of coinfection with hepatitis C virus (HCV and HIV among a cohort of pregnant Thai women. Methods. Samples from 1771 pregnant women enrolled in three vertical transmission of HIV studies in Bangkok, Thailand, were tested for HCV. Results. Among HIV-infected pregnant women, HCV seroprevelance was 3.8% and the active HCV infection rate was 3.0%. Among HIV-uninfected pregnant women, 0.3% were HCV-infected. Intravenous drug use by the woman was the factor most strongly associated with HCV seropositivity. Among 48 infants tested for HCV who were born to HIV/HCV coinfected women, two infants were HCV infected for an HCV transmission rate of 4.2% (95% 0.51–14.25%. Conclusions. HCV seroprevalence and perinatal transmission rates were low among this Thai cohort of HIV-infected pregnant women.

    Many clinical and research findings converge to indicate that frontal lobe, basal ganglia, and related neuronal connections are primarily involved in human immunodeficiency virus (HIV) infection; frontal lobe, mainly the prefrontal cortex, has a specialized role in working memory processes. This study focused on neuropsychological evaluation of the spatial component of working memory in a sample of 34 asymptomatic HIV-infected subjects as compared with 34 age- and sex-matched seronegative control subjects. A computer-administered test assessing spatial working memory was used for the neuropsychological evaluation. The findings did not show any spatial working memory impairment during the asymptomatic phase of HIV infection.

    Full Text Available Cigarette smoking is widespread among HIV-infected patients, who confront increased risk of smoking-related co-morbidities. The effects of HIV infection and HIV-related variables on smoking and smoking cessation are incompletely understood. We investigated the correlates of smoking and quitting in an HIV-infected cohort using a validated natural language processor to determine smoking status.We developed and validated an algorithm using natural language processing (NLP to ascertain smoking status from electronic health record data. The algorithm was applied to records for a cohort of 3487 HIV-infected from a large health care system in Boston, USA, and 9446 uninfected control patients matched 3:1 on age, gender, race and clinical encounters. NLP was used to identify and classify smoking-related portions of free-text notes. These classifications were combined into patient-year smoking status and used to classify patients as ever versus never smokers and current smokers versus non-smokers. Generalized linear models were used to assess associations of HIV with 3 outcomes, ever smoking, current smoking, and current smoking in analyses limited to ever smokers (persistent smoking, while adjusting for demographics, cardiovascular risk factors, and psychiatric illness. Analyses were repeated within the HIV cohort, with the addition of CD4 cell count and HIV viral load to assess associations of these HIV-related factors with the smoking outcomes.Using the natural language processing algorithm to assign annual smoking status yielded sensitivity of 92.4, specificity of 86.2, and AUC of 0.89 (95% confidence interval [CI] 0.88-0.91. Ever and current smoking were more common in HIV-infected patients than controls (54% vs. 44% and 42% vs. 30%, respectively, both P<0.001. In multivariate models HIV was independently associated with ever smoking (adjusted rate ratio [ARR] 1.18, 95% CI 1.13-1.24, P <0.001, current smoking (ARR 1.33, 95% CI 1.25-1.40, P<0.001, and

    2014-01-01

    Full Text Available This paper studies a modified human immunodeficiency virus (HIV infection differential equation model with a saturated infection rate. It is proved that if the basic virus reproductive number R0 of the model is less than one, then the infection-free equilibrium point of the model is globally asymptotically stable; if R0 of the model is more than one, then the endemic infection equilibrium point of the model is globally asymptotically stable. Based on the clinical data from HIV drug resistance database of Stanford University, using the proposed model simulates the dynamics of the two groups of patients’ anti-HIV infection treatment. The numerical simulation results are in agreement with the evolutions of the patients’ HIV RNA levels. It can be assumed that if an HIV infected individual’s basic virus reproductive number R0<1 then this person will recover automatically; if an antiretroviral therapy makes an HIV infected individual’s R0<1, this person will be cured eventually; if an antiretroviral therapy fails to suppress an HIV infected individual’s HIV RNA load to be of unpredictable level, the time that the patient’s HIV RNA level has achieved the minimum value may be the starting time that drug resistance has appeared.

    2009-11-20

    With the advent of highly active antiretroviral agents, women with HIV infection can expect to live longer than ever before. This increased survival has led to concerns about the long-term implications of HIV disease and its treatment. Women with HIV infection appear to lose ovarian function earlier in life than women without HIV infection. They also have evidence of reduced bone mineral density and increased cardiovascular risk. Moreover, many of these increases in risk factors are present even prior to the menopausal transition. All of these risks, present at midlife, augur poorly for future health and describe a substantially increased burden of disease likely to accrue to HIV-infected women as they enter older age groups. Further compounding the adversity faced by the HIV infected, the demographics of women most vulnerable to this disease include adverse social and economic influences, both of which worsen their long-term prognosis. For example, drug use and poverty are related to more severe menopausal symptoms and chronic stress is related to worse psychological and cardiovascular risk. An understanding of how menopause interacts with HIV infection is therefore most important to alert the clinician to perform surveillance for common health problems in postmenopausal women, and to address directly and appropriately symptomatology during the menopausal transition.

    To view methadone maintenance treatment (MMT) globally, it is necessary to accumulate data on MMT policy implementation under different health service systems. The aim of the current study is to provide empirical evidence about policy implementation of MMT and HIV infection control, as well as recommendations for improvement of MMT in the future. Based on China's national policy framework of MMT, policy implementation of MMT in Hubei province has two objectives: 1) to create linkages between health and public security, and 2) to provide integrated services for management of drug abusers. From 2007 to 2011, following the establishment of MMT clinics that provide methadone as well as HIV prevention services, the proportion of HIV infection among drug abusers decreased relatively quickly (12.12% → 5.77% → 5.19% → 2.39% → 2.04%). However, high drop-out rate and poor information management have been identified as particular problems which now need to be addressed. Furthermore, client drop-out from MMT programs may reflect social issues the clients encounter, and consequently, sustainable MMT development requires incorporation of social measures that help MMT clients return to society without discrimination, especially through family cooperation and employment opportunities.

    2015-12-01

    Full Text Available Introduction: As highly active antiretroviral therapy (HAART transforms human immunodeficiency virus (HIV into a manageable chronic disease, new challenges are emerging in treating children born with HIV, including a number of risks to their physical and psychological health due to HIV infection and its lifelong treatment. Methods: We conducted a literature review to evaluate the evidence on the physical and psychological effects of perinatal HIV (PHIV+ infection and its treatment in the era of HAART, including major chronic comorbidities. Results and discussion: Perinatally infected children face concerning levels of treatment failure and drug resistance, which may hamper their long-term treatment and result in more significant comorbidities. Physical complications from PHIV+ infection and treatment potentially affect all major organ systems. Although treatment with antiretroviral (ARV therapy has reduced incidence of severe neurocognitive diseases like HIV encephalopathy, perinatally infected children may experience less severe neurocognitive complications related to HIV disease and ARV neurotoxicity. Major metabolic complications include dyslipidaemia and insulin resistance, complications that are associated with both HIV infection and several ARV agents and may significantly affect cardiovascular disease risk with age. Bone abnormalities, particularly amongst children treated with tenofovir, are a concern for perinatally infected children who may be at higher risk for bone fractures and osteoporosis. In many studies, rates of anaemia are significantly higher for HIV-infected children. Renal failure is a significant complication and cause of death amongst perinatally infected children, while new data on sexual and reproductive health suggest that sexually transmitted infections and birth complications may be additional concerns for perinatally infected children in adolescence. Finally, perinatally infected children may face psychological

    Full Text Available Many new and existing cases of viral hepatitis infections are related to injection drug use. Transmission of these infections can result directly from the use of injection equipment that is contaminated with blood containing the hepatitis B or C virus or through sexual contact with an infected individual. In the latter case, drug use can indirectly contribute to hepatitis transmission through the dis-inhibited at-risk behavior, that is, unprotected sex with an infected partner. Individuals who inject drugs are at-risk for infection from different hepatitis viruses, hepatitis A, B, or C. Those with chronic hepatitis B virus infection also face additional risk should they become co-infected with hepatitis D virus. Protection from the transmission of hepatitis viruses A and B is best achieved by vaccination. For those with a history of or who currently inject drugs, the medical management of viral hepatitis infection comprising screening, testing, counseling and providing care and treatment is evolving. Components of the medical management of hepatitis infection, for persons considering, initiating, or receiving pharmacologic therapy for opioid addiction include: testing for hepatitis B and C infections; education and counseling regarding at-risk behavior and hepatitis transmission, acute and chronic hepatitis infection, liver disease and its care and treatment; vaccination against hepatitis A and B infection; and integrative primary care as part of the comprehensive treatment approach for recovery from opioid abuse and dependence. In addition, participation in a peer support group as part of integrated medical care enhances treatment outcomes. Liver disease is highly prevalent in patient populations seeking recovery from opioid addiction or who are currently receiving pharmacotherapy for opioid addiction. Pharmacotherapy for opioid addiction is not a contraindication to evaluation, care, or treatment of liver disease due to hepatitis virus

    The number of patients newly infected by HIV-1 non-B subtypes and circulating recombinant forms (CRFs) is increasing worldwide, including in the western countries. We report on a primary HIV-1 infection in a Caucasian patient. A routine quantitative assay (Nuclisens EasyQ HIV-1 2.0, BioMérieux SA) showed 6,700 HIV-1 RNA copies/ml. A combined antiretroviral therapy (cART) consistent with low baseline HIV-1 RNA was started. Few days later, the analysis performed with REGA HIV-1 Subtyping Tool - Version 3.0 attributed the HIV-1 sequence to the CRF02_AG recombinant form. Therefore, a second real-time PCR assay was performed, using the Versant HIV-1 RNA 1.0 Assay (kPCR) (Siemens HealthCare Diagnostics) which revealed a HIV-1 RNA of 230,000 copies/ml. Consequently, the ongoing cART was potentiated. This case suggests that the wide genetic variability of HIV-1 subtypes may affect the capability of the commonly used assays to detect and accurately quantify HIV-1 RNA in non-B subtypes and CRFs. In presence of CRFs different commercial HIV-1 RNA tests should be performed to find the most reliable for viral load quantification at the diagnosis, because it influences the choice of cART, and during the follow-up. Indeed, international guidelines for HIV-1 infection management suggest to monitor patient' HIV-RNA with the same assay over the course of treatment. As different commercial tests can be performed in the same laboratory with considerable difficulty, the laboratory should select an assay that is suitable not only for the more prevalent strain, but also for less frequent ones that, nevertheless, can occur. Then, knowing and investigating the spread of non-B strains has essential clinical and laboratory implications. PMID:27196556

    Full Text Available INTRODUCTION: More new HIV-1 infections occur within stable HIV-1-discordant couples than in any other group in Africa, and sexually transmitted infections (STIs may increase transmission risk among discordant couples, accounting for a large proportion of new HIV-1 infections. Understanding correlates of STIs among discordant couples will aid in optimizing interventions to prevent HIV-1 transmission in these couples. METHODS: HIV-1-discordant couples in which HIV-1-infected partners were HSV-2-seropositive were tested for syphilis, chlamydia, gonorrhea, and trichomoniasis, and HIV-1-uninfected partners were tested for HSV-2. We assessed sociodemographic, behavioral, and biological correlates of a current STI. RESULTS: Of 416 couples enrolled, 16% were affected by a treatable STI, and among these both partners were infected in 17% of couples. A treatable STI was found in 46 (11% females and 30 (7% males. The most prevalent infections were trichomoniasis (5.9% and syphilis (2.6%. Participants were 5.9-fold more likely to have an STI if their partner had an STI (P<0.01, and STIs were more common among those reporting any unprotected sex (OR = 2.43; P<0.01 and those with low education (OR = 3.00; P<0.01. Among HIV-1-uninfected participants with an HSV-2-seropositive partner, females were significantly more likely to be HSV-2-seropositive than males (78% versus 50%, P<0.01. CONCLUSIONS: Treatable STIs were common among HIV-1-discordant couples and the majority of couples affected by an STI were discordant for the STI, with relatively high HSV-2 discordance. Awareness of STI correlates and treatment of both partners may reduce HIV-1 transmission. TRIAL REGISTRATION: ClinicalTrials.gov NCT00194519.

    The year 1986 saw first case of HIV infection as well as first report of AIDS case in India. Since then the epidemic has spread throughout the country. In the recent years there is evidence of epidemic being stabilized with decrease in new infections reported from some parts of the country. The absolute number of HIV infections in the country is expected to be close to 2.5 million and National AIDS Control Programme, phase III is geared to contain the epidemic. HIV viruses circulating in India predominantly belong to HIV-1 subtype C. However, there have been occasional reports of HIV-1 subtype A and B. Matter of concern is reports of A/C and B/C mosaic viruses that are being reported from different parts of the country. The data on HIV drug resistance from India is rather limited. Most of the studies have shown that the virus strains from drug naïve patients do not show significant level of drug resistance mutations. The few immunological studies in Indian patients show that the Indian HIV infected patients show both HIV-specific CTL responses as well as neutralizing antibody response. Mapping of CTL epitopes showed that while Indian patients identify same regions of Gag antigen as recognized by South African subtype C infected patients, some regions are uniquely recognized by Indian patients. There are very few studies on host genetic factors in India in context with HIV infection. However there are evidences reported of association of host genetic factors such as HLA types and haplotypes and HIV disease.

    Existing studies have delineated that HIV-infected parents face numerous challenges in disclosing their HIV infection to the children ("parental HIV disclosure"), and practices of parental HIV disclosure vary with individual characteristics, family contexts, and social environment. Using cross-sectional data from 1254 HIV-infected parents who had children aged 5-16 years in southwest China, the current study examined the association of parental HIV disclosure with mental health and medication adherence among parents and explored the possible effect of enacted stigma on such association. Multivariate analysis of variance revealed that parents who had experienced disclosure to children reported higher level enacted stigma, worse mental health conditions, and poorer medication adherence. Enacted stigma partially mediated the associations between disclosure and both mental health and medication adherence after controlling basic background characteristics. Our findings highlight the importance of providing appropriate disclosure-related training and counseling service among HIV-infected parents. In a social setting where HIV-related stigma is still persistent, disclosure intervention should address and reduce stigma and discrimination in the practice of parental HIV disclosure.

    HIV-1 infection afflicts more than 35 million people worldwide, according to 2014 estimates from the World Health Organization. For those individuals who have access to antiretroviral therapy, these drugs can effectively suppress, but not cure, HIV-1 infection. Indeed, the only documented case for an HIV/AIDS cure was a patient with HIV-1 and acute myeloid leukemia who received allogeneic hematopoietic cell transplantation (HCT) from a graft that carried the HIV-resistant CCR5-∆32/∆32 mutation. Other attempts to establish a cure for HIV/AIDS using HCT in patients with HIV-1 and malignancy have yielded mixed results, as encouraging evidence for virus eradication in a few cases has been offset by poor clinical outcomes due to the underlying cancer or other complications. Such clinical strategies have relied on HIV-resistant hematopoietic stem and progenitor cells that harbor the natural CCR5-∆32/∆32 mutation or that have been genetically modified for HIV-resistance. Nevertheless, HCT with HIV-resistant cord blood remains a promising option, particularly with inventories of CCR5-∆32/∆32 units or with genetically modified, human leukocyte antigen-matched cord blood.

    By using the state space model (Kalman filter model) of the HIV epidemic, in this paper we have developed a general Bayesian procedure to estimate simultaneously the HIV infection distribution, the HIV incubation distribution, the numbers of susceptible people, infective people and AIDS cases. The basic approach is to use the Gibbs sampling method combined with the weighted bootstrap method. We have applied this method to the San Francisco AIDS incidence data from January 1981 to December 1992. The results show clearly that both the probability density function of the HIV infection and the probability density function of the HIV incubation are curves with two peaks. The results of the HIV infection distribution are clearly consistent with the finding by Tan et al. [W.Y. Tan, S.C. Tang, S.R. Lee, Estimation of HIV seroconversion and effects of age in San Francisco homosexual populations, J. Appl. Stat. 25 (1998) 85]. The results of HIV incubation distribution seem to confirm the staged model used by Satten and Longini [G. Satten, I. Longini, Markov chain with measurement error: estimating the 'true' course of marker of the progression of human immunodeficiency virus disease, Appl. Stat. 45 (1996) 275]. PMID:10942785

    2015-04-01

    Significance: Latent tuberculosis, which affects an estimated 1/3 of the world's population, has long been thought to be a relatively benign, quiescent state of M. tuberculosis infection. While HIV co-infection is known to exacerbate M. tuberculosis infection and increase the risk of developing active TB, little is known about the potential effect of latent TB infection on HIV disease. This study shows that HIV-infected individuals with both active and latent TB have elevated levels of inflammation and immune activation, biomarkers of HIV disease progression and elevated risk of mortality. These results suggest that, in the context of HIV, latent TB infection may be associated with increased risk of progression to AIDS and mortality.

    Recent Indigenist scholarship has situated high rates of traumatic life experiences, including sexual abuse, among Indigenous peoples of North America within the larger context of their status as colonized peoples. Sexual abuse has been linked to many negative health outcomes including mental, sexual and drug-related vulnerabilities. There is a paucity of research in Canada addressing the relationship between antecedent sexual abuse and negative health outcomes among Aboriginal people including elevated risk of HIV infection. The primary objectives of this study were to determine factors associated with sexual abuse among participants of the Cedar Project, a cohort of young Aboriginal people between the ages of 14 and 30 years who use injection and non-injection drugs in two urban centres in British Columbia, Canada; and to locate findings through a lens of historical and intergenerational trauma. We utilized post-colonial perspectives in research design, problem formulation and the interpretation of results. Multivariate modeling was used to determine the extent to which a history of sexual abuse was predictive of negative health outcomes and vulnerability to HIV infection. Of the 543 eligible participants, 48% reported ever having experienced sexual abuse; 69% of sexually abused participants were female. The median age of first sexual abuse was 6 years for both female and male participants. After adjusting for sociodemographic variables and factors of historical trauma, sexually abused participants were more likely to have ever been on the streets for more than three nights, to have ever self-harmed, to have suicide ideation, to have attempted suicide, to have a diagnosis of mental illness, to have been in the emergency department within the previous 6 months, to have had over 20 lifetime sexual partners, to have ever been paid for sex and to have ever overdosed. The prevalence and consequences of sexual abuse among Cedar Project participants are of grave concern

    Full Text Available Human Immunodeficiency Virus (HIV infection and the resultant Acquired Immunodeficiency Syndrome (AIDS epidemic are major global health challenges; hepatitis C virus (HCV co-infection has made the HIV/AIDS epidemic even worse. Interleukin-27 (IL-27, a cytokine which inhibits HIV and HCV replication in vitro, associates with HIV infection and HIV/HCV co-infection in clinical settings. However, the impact of HIV and HCV viral loads on plasma IL-27 expression levels has not been well characterized. In this study, 155 antiretroviral therapy-naïve Chinese were recruited. Among them 80 were HIV- and HCV-negative healthy controls, 45 were HIV-mono-infected and 30 were HIV/HCV-co-infected. Plasma level HIV, HCV, IL-27 and CD4+ number were counted and their correlation, regression relationships were explored. We show that: plasma IL-27 level was significantly upregulated in HIV-mono-infected and HIV/HCV-co-infected Chinese; HIV viral load was negatively correlated with IL-27 titer in HIV-mono-infected subjects whereas the relationship was opposite in HIV/HCV-co-infected subjects; and the relationships between HIV viral loads, IL-27 titers and CD4+ T cell counts in the HIV mono-infection and HIV/HCV co-infection groups were dramatically different. Overall, our results suggest that IL-27 differs in treatment-naïve groups with HIV mono-infections and HIV/HCV co-infections, thereby providing critical information to be considered when caring and treating those with HIV mono-infection and HIV/HCV co-infection.

    The analysis of the morbidity dynamics of HIV infection, hepatitis B and C in the Krasnodar territory for 1996-2003 is presented. The tendency of strengthening direct correlation between age-dependent rates in these groups of diseases has been established. The correlation coefficient (rxy) is at present +0.851 (HIV infection-virus hepatitis B) and +0.892 (HIV infection-virus hepatitis C). The highest levels of primary morbidity are registered in persons aged 20-39 years. The established epidemiological parallels between HIV infection and parenteral hepatitis require the development of the unified strategy of the prophylaxis of these diseases on the federal and regional levels.

    Full Text Available The great success in the prevention and treatment of pediatric HIV in high resource countries, and now in low resource countries, has changed the face of the HIV epidemic in children from one of near certain mortality to that of a chronic disease. However, these successes pose new challenges as perinatally HIV-infected youth survive into adulthood. Increased survival of HIV-infected children is associated with challenges in maintaining adherence to what is likely life-long therapy, and in selecting successive antiretroviral drug regimens, given the limited availability of pediatric formulations, limitations in pharmacokinetic and safety data of drugs in children, and the development of extensive drug resistance in multi-drug-experienced children. Pediatric HIV care must now focus on morbidity related to long-term HIV infection and its treatment. Survival into adulthood of perinatally HIV-infected youth in high resource countries provides important lessons about how the epidemic will change with increasing access to antiretroviral therapy for children in low resource countries. This series of papers will focus on issues related to management of perinatally infected youth and young adults.

    Full Text Available By 2020 the prevalence of HIV in the Russian Federation may increase by 250%, unless we provide appropriate treatment to as many HIV-infected people as possible (V.I. Skvortsova, 2015. Previous research in this field shows that the psychotraumatic character of the disease lowers the psychological resource of HIV-infected individuals. In most cases, they are not psychologically prepared for the negative life events, unable to find an optimal behavioral pattern when their life stereotypes are being destroyed. In fact, being HIV-infected is an example of an acute event (V.V. Pokrovsky, 1993. The ability to overcome the life crisis and effectiveness of using adaptation and compensatory mechanisms to fight the disease depend on the level of adaptation to the fact of being infected and resistance to stress. The aim of the current study was to determine social and psychological features of HIV-infected individuals and assess their influence on the stress resistance and adaptation abilities of HIV+ patients. We observed men and women aged 21-30 who had been HIV+ for 1-5 years. Investigation methods included the following diagnostic tools: The Cattel Sixteen Personality Factor Questionnaire (Form C, The State-Trait Anxiety Inventory (conducted by Spielberger, adapted for use in Russia by Hanin, The Social Readjustment Rating Scale (The Holmes-Rahe Stress Inventory, The Social and Psychological Adaptation Questionnaire (by C. Rogers and R. Diamond, methods of mathematical statistics. As a result of the study, we have developed comparative factor profiles of individual psychological features of HIV-infected individuals that show their dependence on the social environment and form certain behavioral patterns. We have revealed significant difference in state and trait anxiety between HIV-infected and non-HIV-infected individuals. Self-blame, inadequate self-esteem and level of aspiration indicate low cognitive assessment of the condition by the patients

    Background HIV-1 acute infection, recent infection and transmitted drug resistance screening was integrated into voluntary HIV counseling and testing (VCT) services to enhance the existing surveillance program in San Francisco. This study describes newly-diagnosed HIV cases and characterizes correlates associated with infection. Methodology/Principal Findings A consecutive sample of persons presenting for HIV VCT at the municipal sexually transmitted infections (STI) clinic from 2004 to 2006 (N = 9,868) were evaluated by standard enzyme-linked immunoassays (EIA). HIV antibody-positive specimens were characterized as recent infections using a less-sensitive EIA. HIV-RNA pooled testing was performed on HIV antibody-negative specimens to identify acute infections. HIV antibody-positive and acute infection specimens were evaluated for drug resistance by sequence analysis. Multivariable logistic regression was performed to evaluate associations. The 380 newly-diagnosed HIV cases included 29 acute infections, 128 recent infections, and 47 drug-resistant cases, with no significant increases or decreases in prevalence over the three years studied. HIV-1 transmitted drug resistance prevalence was 11.0% in 2004, 13.4% in 2005 and 14.9% in 2006 (p = 0.36). Resistance to non-nucleoside reverse transcriptase inhibitors (NNRTI) was the most common pattern detected, present in 28 cases of resistance (59.6%). Among MSM, recent infection was associated with amphetamine use (AOR = 2.67; p<0.001), unprotected anal intercourse (AOR = 2.27; p<0.001), sex with a known HIV-infected partner (AOR = 1.64; p = 0.02), and history of gonorrhea (AOR = 1.62; p = 0.03). Conclusions New HIV diagnoses, recent infections, acute infections and transmitted drug resistance prevalence remained stable between 2004 and 2006.

    Full Text Available The purpose of the present study was to determine the vulnerability of women in prison to HIV infection. The study was carried out from August to October 2000 in a São Paulo State Penitentiary, where 299 female prisoners were serving time. We interviewed and obtained a blood sample from 290 females who agreed to enter the study. Sera were tested for the presence of antibodies to HIV, hepatitis C virus (HCV and syphilis and the odds ratio (OR was calculated for variables related to HIV positivity on the basis of a questionnaire. The overall prevalence data were: 13.9% for HIV (37 of 267, 22.8% for syphilis (66 of 290, and 16.2% for HCV (47 of 290. Sexual partnership variables were significantly related to HIV infection. These included HIV-positive partners (OR = 7.36, P = 0.0001, casual partners (OR = 8.96, P = 0.009, injectable drug user partners (OR = 4.7, P = 0.0001, and history of sexually transmitted disease (OR = 2.07, P = 0.05. In addition, a relationship was detected between HIV infection and drug use (OR = 2.48, P = 0.04 and injectable drug use (OR = 4.2, P = 0.002. Even women with only one partner presented a significant OR for HIV infection (OR = 2.57, P = 0.009, reflecting their vulnerability due to their trust in their partner, who did not use a condom. Although the use of injectable substances is associated with HIV infection, our results point to sexual behavior as the most important component of HIV transmission in the female prisoner population.

However, the relationship of type and severity of IPV with PTSD in this population has not been adequately explored. We focus on the association between the type and severity of IPV and HIV status and PTSD in a sample of South African women. One hundred and sixty-nine women (114 HIV-positive and 55 HIV-negative controls), matched for geographical area, education, and socio-economic status, were recruited from HIV clinics. Clinical and demographic data were collected, including data on childhood trauma, other traumatic life events, IPV, posttraumatic stress symptoms, problematic alcohol use, and depressive symptoms. HIV-positive women had significantly more depressive symptoms, alcohol abuse, and childhood trauma exposure as well as significantly higher rates of PTSD (25.4%) when compared with uninfected women (10.9%). No significant group differences in the rate, pattern, and severity of physical, sexual, psychological, injury, and negotiation IPV were found. In logistic regression analysis, the rate and severity category of IPV did not significantly predict PTSD in HIV-positive women when childhood trauma and life events were controlled for. Our results indicate the need for screening for alcohol abuse, PTSD and depressive symptoms at HIV wellness, and ARV clinics. The high rates of PTSD in HIV-positive women indicate the need for specialized programs to manage PTSD and minimize negative sequelae in this population. These results also highlight the need for improved screening and prevention of childhood trauma and IPV both in infected and uninfected women.

    Full Text Available INTRODUCTION: HIV-1 is often acquired in the presence of pre-existing co-infections, such as Herpes Simplex Virus 2 (HSV-2. We examined the impact of HSV-2 status at the time of HIV-1 acquisition for its impact on subsequent clinical course, and total CD4+ T cell phenotypes. METHODS: We assessed the relationship of HSV-1/HSV-2 co-infection status on CD4+ T cell counts and HIV-1 RNA levels over time prior in a cohort of 186 treatment naïve adults identified during early HIV-1 infection. We assessed the activation and differentiation state of total CD4+ T cells at study entry by HSV-2 status. RESULTS: Of 186 recently HIV-1 infected persons, 101 (54% were sero-positive for HSV-2. There was no difference in initial CD8+ T cell count, or differences between the groups for age, gender, or race based on HSV-2 status. Persons with HIV-1/HSV-2 co-infection sustained higher CD4+ T cell counts over time (+69 cells/ul greater (SD = 33.7, p = 0.04 than those with HIV-1 infection alone (Figure 1, after adjustment for HIV-1 RNA levels (-57 cells per 1 log(10 higher HIV-1 RNA, p<0.0001. We did not observe a relationship between HSV-2 infection status with plasma HIV-1 RNA levels over time. HSV-2 acquisition after HIV-1 acquisition had no impact on CD4+ count or viral load. We did not detect differences in CD4+ T cell activation or differentiation state by HSV-2+ status. DISCUSSION: We observed no effect of HSV-2 status on viral load. However, we did observe that treatment naïve, recently HIV-1 infected adults co-infected with HSV-2+ at the time of HIV-1 acquisition had higher CD4+ T cell counts over time. If verified in other cohorts, this result poses a striking paradox, and its public health implications are not immediately clear.

    Objective: Several pieces of evidence indicate that HIV-infected adults undergo premature aging. The effect of HIV and antiretroviral therapy (ART) exposure on the aging process of HIV-infected children may be more deleterious since their immune system coevolves from birth with HIV. Design: Seventy-one HIV-infected (HIV+), 65 HIV-exposed-uninfected (HEU), and 56 HIV-unexposed-uninfected (HUU) children, all aged 0–5 years, were studied for biological aging and immune senescence. Methods: Telomere length and T-cell receptor rearrangement excision circle levels were quantified in peripheral blood cells by real-time PCR. CD4+ and CD8+ cells were analysed for differentiation, senescence, and activation/exhaustion markers by flow cytometry. Results: Telomere lengths were significantly shorter in HIV+ than in HEU and HUU children (overall, P < 0.001 adjusted for age); HIV+ ART-naive (42%) children had shorter telomere length compared with children on ART (P = 0.003 adjusted for age). T-cell receptor rearrangement excision circle levels and CD8+ recent thymic emigrant cells (CD45RA+CD31+) were significantly lower in the HIV+ than in control groups (overall, P = 0.025 and P = 0.005, respectively). Percentages of senescent (CD28−CD57+), activated (CD38+HLA-DR+), and exhausted (PD1+) CD8+ cells were significantly higher in HIV+ than in HEU and HUU children (P = 0.004, P < 0.001, and P < 0.001, respectively). Within the CD4+ cell subset, the percentage of senescent cells did not differ between HIV+ and controls, but programmed cell death receptor-1 expression was upregulated in the former. Conclusions: HIV-infected children exhibit premature biological aging with accelerated immune senescence, which particularly affects the CD8+ cell subset. HIV infection per se seems to influence the aging process, rather than exposure to ART for prophylaxis or treatment. PMID:26990630

    The secrecy surrounding the disease of parents and children infected with HIV leads to psychic and affective isolation and difficulties of communication within the family. Psychological management may possibly help to resolve the problem of secrecy between parents and children. We analyzed the organization and dynamics of the secret surrounding children contaminated by their mothers. The analysis was prospective and was based on semi-directive interviews and drawings. We followed up, over a period of two years, ten children (mean age: 4 years, range: 4 months to 12 years) with different ethnic and socio economic backgrounds. In each family, the child was the target of the secret, the pediatrician the guardian, and the mother (or her substitute) the keeper. The organization of the secret around the other potential guardians varied from one family to another. Two modes of intra-family communication were observed: the secret (reserved for the youngest children) and the tacit. One child suffered from a disorder related to the secret, the others had depressive and reactional symptoms. At the end of the study, the manner of approaching, and especially dealing with, the question of the secret had changed appreciably in each family: disclosure to the family circle (three cases), passage of the child from the secret to the tacit (two cases), and easier questioning of the pediatrician in all of the cases. Nonetheless, in no case had the secret been completely lifted for the child. Four children asked to continue psychological management. The changes in the dynamics of the secret and the appeasement observed in the families suggest that psychotherapeutic aid should be offered to families where a child has been contaminated with HIV by the mother.

    Full Text Available HIV/AIDS is among the leading causes of morbidity and mortality in world. There are more than 35 million people living with HIV/AIDS in the world. Although the annual incidence of HIV infection is decreasing globally, HIV prevalence is rising due to development of more effective treatment and higher survival. Iran suffers from concentrated HIV epidemics among injecting and non-injecting drug users. There are more than 27 thousand registered cases of HIV infection and it is estimated that there are above seventy eight thousand cases in the country. Regarding the burden of disease, it is projected that HIV/AIDS will have the highest growth during the next 10 years. The outcome of this epidemics will be determined by human behavior. HIV, psychiatric disorders and substance use disorders are closely correlated and are accompanied by similar risk factors. They also share common consequences such as stigma and discrimination. Correlation of psychiatric disorders, as one of the most influential determinants of our behavior, and HIV/AIDS infection is reviewed in this narrative article. Psychiatric disorders are associated with greater risk of HIV acquisition. Substance use disorders, both injecting and non-injecting, as well as severe mental illnesses put the individual at higher risk of acquiring HIV infection. Impaired judgment, diminished inhibition and control over behaviors, lack of insight and poor self-care have been proposed as the underlying mechanisms. On the other hand, HIV infection may put the individual at greater risk of developing a mental illness. Coping with a chronic and life-threatening illness, fear of stigma and discrimination, CNS invasion of the virus as well as the adverse neuropsychiatric side effects of anti-retroviral medications may all contribute to establishment of a psychiatric disorder. Although there exists a bi-directional correlation between mental health problems and HIV/AIDS infection, this reciprocity goes beyond

    A functional HIV-1 cure has been possible now.The ideal functional HIV-1 cure should get HIV-1 infected patients to the point where drugs are not needed after combination therapy and HIV-1 RNA cannot be detected in some patients.However,a functional HIV-1 cure is not equal to a cure for HIV-1,because HIV-1 RNA can still be detected in patients' latent infected cells and related symptoms have not been resolved completely.An era of eradication cure for HIV infection will be coming with further basic and clinical studies,especially when cleaning virus reservoirs by gene modifications successfully.%目前,HIV-1感染治疗已发展到“功能性治愈”阶段,即采用联合化疗一段时间后停止用药几年内,可以使部分患者体内的病毒达到检测不出的水平.然而,这还不是治愈,因为患者的静止淋巴细胞内仍可查到病毒痕迹,患者临床症状也并未完全消失.真正的治愈还须进行更深入的基础和临床研究,特别是通过基因修饰清除病毒的藏身之地.

    2004-01-01

    Full Text Available Infection with HIV may develop to AIDS at different rates in different individuals, with a spectrum varying from rapid progression to long term non-progression. The variable course of HIV-1 infection causes emotional trauma for the infected person and complicates the design and interpretation of therapeutic trials because of unrecognized differences in prognosis. Thus it is essential to have tests which can accurately assess the stage of infection in an individual, as well as predict its course and monitor its progression. These laboratory tests are very valuable during the period of clinical latency and subsequently supplement various clinical parameters.

    The internal N6-methyladenosine (m6A) methylation of eukaryotic nuclear RNA controls post-transcriptional gene expression, which is regulated by methyltransferases (writers), demethylases (erasers), and m6A-binding proteins (readers) in cells. The YTH domain family proteins (YTHDF1–3) bind to m6A-modified cellular RNAs and affect RNA metabolism and processing. Here, we show that YTHDF1–3 proteins recognize m6A-modified HIV-1 RNA and inhibit HIV-1 infection in cell lines and primary CD4+ T-cells. We further mapped the YTHDF1–3 binding sites in HIV-1 RNA from infected cells. We found that the overexpression of YTHDF proteins in cells inhibited HIV-1 infection mainly by decreasing HIV-1 reverse transcription, while knockdown of YTHDF1–3 in cells had the opposite effects. Moreover, silencing the m6A writers decreased HIV-1 Gag protein expression in virus-producing cells, while silencing the m6A erasers increased Gag expression. Our findings suggest an important role of m6A modification of HIV-1 RNA in viral infection and HIV-1 protein synthesis. DOI: http://dx.doi.org/10.7554/eLife.15528.001 PMID:27371828

    Full Text Available Studies on HIV virology and pathogenesis address the complex mechanisms that result in the HIV infection of the cell and destruction of the immune system. These studies are focused on both the structure and the replication characteristics of HIV and on the interaction of the virus with the host. Continuous updating of knowledge on structure, variability and replication of HIV, as well as the characteristics of the host immune response, are essential to refine virological and immunological mechanisms associated with the viral infection and allow us to identify key molecules in the virus life cycle that can be important for the design of new diagnostic assays and specific antiviral drugs and vaccines. In this article we review the characteristics of molecular structure, replication and pathogenesis of HIV, with a particular focus on those aspects that are important for the design of diagnostic assays.

    This case report describes the use of Spiritual Self-Schema (3-S) therapy in the treatment of an HIV-positive inner-city drug user maintained on methadone and referred for additional treatment due to unremitting cocaine use. 3-S therapy is a manual-guided intervention based on cognitive self-schema theory. Its goal is to help the patient create, elaborate, and make accessible a cognitive schema--the "spiritual" self-schema-that is incompatible with drug use and other HIV risk behaviors. 3-S therapy facilitates a cognitive shift from the habitual activation of the "addict" self-schema, with its drug-related cognitions, scripts and action plans, to the "spiritual" self-schema, with its associated repertoire of harm reduction beliefs and behaviors.

    2010-06-01

    Full Text Available Abstract The pathogenesis of HIV infection, and in particular the development of immunodeficiency, remains incompletely understood. Whichever intricate molecular mechanisms are at play between HIV and the host, it is evident that the organism is incapable of restricting and eradicating the invading pathogen. Both innate and adaptive immune responses are raised, but they appear to be insufficient or too late to eliminate the virus. Moreover, the picture is complicated by the fact that the very same cells and responses aimed at eliminating the virus seem to play deleterious roles by driving ongoing immune activation and progressive immunodeficiency. Whereas much knowledge exists on the role of adaptive immunity during HIV infection, it has only recently been appreciated that the innate immune response also plays an important part in HIV pathogenesis. In this review, we present current knowledge on innate immune recognition and activation during HIV infection based on studies in cell culture, non-human primates, and HIV-infected individuals, and discuss the implications for the understanding of HIV immunopathogenesis.

    Osteonecrosis is a rare complication of HIV infection. The presumptive cause of the aseptic osteonecrosis is a distrubed blood supply to the bone. Most cases of osteonecrosis are associated with numerous risk factors, such as use of steroids, alcohol abuse, coagulopathies or metabolic derangements. Since conventional X-rays appear unremarkable, early forms often go unrecognized or are diagnosed late. Methods of establishing the diagnosis are MRI and three-phase skeletal scintigraphy. The pathogenesis of osteonecrosis in HIV infection is unclear. So far, about 30 cases have been reported in the literature. We would recommend that in HIV patients with typical symptoms - in particular when classical risk factors are present - osteonecrosis be included in the differential diagnostic considerations. (orig.) [German] Die Osteonekrose ist eine seltene Komplikation der HIV-Infektion. Als Ursache werden Stoerungen in der Gefaessversorgung des Knochengewebes angenommen. Aufgrund unauffaelliger Befunde im konventionellen Roentgen werden Fruehformen haeufig verkannt oder erst verspaetet diagnostiziert. Methoden zur Diagnosesicherung sind die Kernspintomographie oder die 3-Phasen-Knochenszintigraphie. Die Pathogenese der Osteonekrose bei der HIV-Infektion ist unklar. Bisher sind in der Literatur etwa 30 Kasuistiken beschrieben. Wir empfehlen, bei Vorliegen einer typischen Symptomatik bei HIV-Patienten - insbesondere wenn typische Risikofaktoren vorliegen - die Osteonekrose in die differenzialdiagnostischen Ueberlegungen mit einzubeziehen.

    There is a critical need to examine protective and risk factors of anxiety and depressive symptoms among people living with HIV in order to improve quality of life. Structural equation modeling was used to examine the associations between HIV-related shame, sexual abuse-related shame, posttraumatic growth, and anxiety and depressive symptoms among a cohort of 225 heterosexual women and men who have sex with men (MSM) living with HIV who have experienced childhood sexual abuse (CSA). Higher sexual abuse-related shame was related to more anxiety and depressive symptoms for heterosexual women. Higher posttraumatic growth predicted less anxiety symptoms for only heterosexual women. Higher posttraumatic growth predicted less depressive symptoms for heterosexual women and MSM, but the magnitude of this effect was stronger for heterosexual women than MSM. Psychosocial interventions may need to be tailored to meet the specific needs of heterosexual women and MSM living with HIV and CSA. PMID:26837633

    Directory of Open Access Journals (Sweden)

    Donna L Rudolph

    Full Text Available A rapid, cost-effective diagnostic test for the detection of acute HIV-1 infection is highly desired. Isothermal amplification techniques, such as reverse-transcription loop-mediated isothermal amplification (RT-LAMP, exhibit characteristics that are ideal for the development of a rapid nucleic acid amplification test (NAAT because they are quick, easy to perform and do not require complex, dedicated equipment and laboratory space. In this study, we assessed the ability of the HIV-1 RT-LAMP assay to detect acute HIV infection as compared to a representative rapid antibody test and several FDA-approved laboratory-based assays. The HIV-1 RT-LAMP assay detected seroconverting individuals one to three weeks earlier than a rapid HIV antibody test and up to two weeks earlier than a lab-based antigen/antibody (Ag/Ab combo enzyme immunoassay (EIA. RT-LAMP was not as sensitive as a lab-based qualitative RNA assay, which could be attributed to the significantly smaller nucleic acid input volume. To our knowledge, this is the first demonstration of detecting acute HIV infection using the RT-LAMP assay. The availability of a rapid NAAT, such as the HIV-1 RT-LAMP assay, at the point of care (POC or in laboratories that do not have access to large platform NAAT could increase the percentage of individuals who receive an acute HIV infection status or confirmation of their HIV status, while immediately linking them to counseling and medical care. In addition, early knowledge of HIV status could lead to reduced high-risk behavior at a time when individuals are at a higher risk for transmitting the virus.

    Full Text Available OBJECTIVES: Nucleoside reverse transcriptase inhibitors (NRTIs used in HIV antiretroviral therapy can inhibit human telomerase reverse transcriptase. We therefore investigated whether in utero or childhood exposure to NRTIs affects leukocyte telomere length (LTL, a marker of cellular aging. METHODS: In this cross-sectional CARMA cohort study, we investigated factors associated with LTL in HIV-1-infected (HIV(+ children (n = 94, HIV-1-exposed uninfected (HEU children who were exposed to antiretroviral therapy (ART perinatally (n = 177, and HIV-unexposed uninfected (HIV(- control children (n = 104 aged 0-19 years. Univariate followed by multivariate linear regression models were used to examine relationships of explanatory variables with LTL for: a all subjects, b HIV(+/HEU children only, and c HIV(+ children only. RESULTS: After adjusting for age and gender, there was no difference in LTL between the 3 groups, when considering children of all ages together. In multivariate models, older age and male gender were associated with shorter LTL. For the HIV(+ group alone, having a detectable HIV viral load was also strongly associated with shorter LTL (p = 0.007. CONCLUSIONS: In this large study, group rates of LTL attrition were similar for HIV(+, HEU and HIV(- children. No associations between children's LTL and their perinatal ART exposure or HIV status were seen in linear regression models. However, the association between having a detectable HIV viral load and shorter LTL suggests that uncontrolled HIV viremia rather than duration of ART exposure may be associated with acceleration of blood telomere attrition.

    Full Text Available Retrospective research of 381 clinical records is conducted to study HIV infection influence on stationary stage of tuberculosis treatment outcome in HIV-TB co-infected patients. All cases were divided depending on a hospitalization outcome on favorable and adverse. At most of patients tuberculosis of respiratory organs met. Immunological researches were conducted, the stage of HIV infection was registered and the issue of purpose of anti-retroviral therapy was resolved. Besides, as indirect signs of an immunodeficiency at the patients with a combination of tuberculosis and HIV infection who were on hospitalization the indicators received when carrying out clinical laboratory trials were analyzed: absolute and relative quantity of lymphocytes according to the general blood test, the contents the globulin fractions and circulating immune complexes concentration according to the clinical chemistry blood test. At an assessment of results in both groups of research more than at a half of patients existence of HIV infection at late stages that speaks about late identification and neglect of an immunodeficiency was revealed. At patients with tuberculosis of lungs in combination with HIV infection at a failure statistically significant decrease in an immunoregulatory index is revealed. It is interesting that the level of CD4 lymphocytes and a stage of HIV infection had no impact on the co-infection’s outcome. However, existence of virus loa ding more than 100 000 copies/ml reduced probability favorable an outcome of treatment of tuberculosis at the patient with HIV infection. Timely purpose of anti-retroviral therapy at patients with co-infection increased chances of treatment of tuberculosis at patients with an immunodeficiency.

    Background & objectives: Hepatitis B virus (HBV) and HIV co-infection has variable prevalence worldwide. In comparison to HBV mono-infection, the course of chronic HBV infection is accelerated in HIV/HBV co-infected patients. The present study was carried out to analyse the baseline characteristics (clinical, biochemical, serological and virological) of treatment naïve HIV/HBV co-infected and HIV mono-infected patients. Methods: Between July 2011 and January 2013, a total number of 1331 HIV-seropositive treatment naïve individuals, enrolled in the ART Centre of Calcutta School of Tropical Medicine, Kolkata, India, were screened for hepatitis B surface antigen (HBsAg). A total of 1253 HIV mono-infected and 78 HIV/HBV co-infected patients were characterized. The co-infected patients were evaluated for HBeAg and anti-HBe antibody by ELISA. HIV RNA was quantified for all co-infected patients. HBV DNA was detected and quantified by real time-PCR amplification followed by HBV genotype determination. Results: HIV/HBV co-infected patients had proportionately more advanced HIV disease (WHO clinical stage 3 and 4) than HIV mono-infected individuals (37.1 vs. 19.9%). The co-infected patients had significantly higher serum bilirubin, alanine aminotransferase (ALT), alkaline phosphatase and ALT/platelet ratio index (APRI). CD4 count was non-significantly lower in co-infected patients. Majority (61.5%) were HBeAg positive with higher HIV RNA (PHIV/HBV co-infected patients had significantly higher serum bilirubin, ALT, alkaline phosphatase and lower platelet count. HBeAg positive co-infected patients had higher HIV RNA and HBV DNA compared to HBeAg negative co-infected patients. Prior to initiation of antiretroviral treatment (ART) all patients should be screened for HBsAg to initiate appropriate ART regimen. PMID:27488008

    This paper reviews currently available PET studies performed either to improve our understanding of the pathogenesis of HIV-1 infection or to assess the value of PET imaging in the clinical decision making of patients infected with HIV-1 presenting with AIDS-related opportunistic infections and malignancies. FDG PET has shown that HIV-1 infection progresses by distinct anatomical steps, with involvement of the upper torso preceding involvement of the lower part of the torso, and that the degree of FDG uptake relates to viral load. The former finding suggests that lymphoid tissues are engaged in a predictable sequence and that diffusible mediators of activation might be important targets for vaccine or therapeutic intervention strategies. In lipodystrophic HIV-infected patients, limited available data support the hypothesis that stavudine-related lipodystrophy is associated with increased glucose uptake by adipose tissue as a result of the metabolic stress of adipose tissue in response to highly active antiretroviral treatment (HAART). Finally, in early AIDS-related dementia complex (ADC), striatal hypermetabolism is observed, whereas progressive ADC is characterized by a decrease in subcortical and cortical metabolism. In the clinical setting, PET has been shown to allow the differentiation of AIDS-related opportunistic infections and malignancies, and to allow monitoring of side effects of HAART. However, in patients suffering from HIV infection and presenting with extracerebral lymphoma or other human malignancies, knowledge of viraemia is essential when interpreting FDG PET imaging.

    2012-01-01

    Despite its discovery over 30 years ago, human immunodeficiency virus (HIV) continues to threaten public health worldwide. Semen is the principal vehicle for the transmission of this retrovirus and several endogenous peptides in semen, including fragments of prostatic acid phosphatase (PAP248-286 and PAP85-120) and semenogelins (SEM1 and SEM2), assemble into amyloid fibrils that promote HIV infection. For example, PAP248-286 fibrils, termed SEVI (Semen derived Enhancer of Viral Infection), potentiate HIV infection by up to 105-fold. Fibrils enhance infectivity by facilitating virion attachment and fusion to target cells, whereas soluble peptides have no effect. Importantly, the stimulatory effect is greatest at low viral titers, which mimics mucosal transmission of HIV, where relatively few virions traverse the mucosal barrier. Devising a method to rapidly reverse fibril formation (rather than simply inhibit it) would provide an innovative and urgently needed preventative strategy for reducing HIV infection via the sexual route. Targeting a host-encoded protein conformer represents a departure from traditional microbicidal approaches that target the viral machinery, and could synergize with direct antiviral approaches. Here, we review the identification of these amyloidogenic peptides, their mechanism of action, and various strategies for inhibiting their HIV-enhancing effects.

    Full Text Available Abstract Background Central nervous system (CNS exposure to HIV is a universal facet of systemic infection. Because of its proximity to and shared barriers with the brain, cerebrospinal fluid (CSF provides a useful window into and model of human CNS HIV infection. Methods Prospective study of the relationships of CSF to plasma HIV RNA, and the effects of: 1 progression of systemic infection, 2 CSF white blood cell (WBC count, 3 antiretroviral therapy (ART, and 4 neurological performance. One hundred HIV-infected subjects were cross-sectionally studied, and 28 were followed longitudinally after initiating or changing ART. Results In cross-sectional analysis, HIV RNA levels were lower in CSF than plasma (median difference 1.30 log10 copies/mL. CSF HIV viral loads (VLs correlated strongly with plasma VLs and CSF WBC counts. Higher CSF WBC counts associated with smaller differences between plasma and CSF HIV VL. CSF VL did not correlate with blood CD4 count, but CD4 counts In subjects starting ART, those with lower CD4 counts had slower initial viral decay in CSF than in plasma. In all subjects, including five with persistent plasma viremia and four with new-onset ADC, CSF HIV eventually approached or reached the limit of viral detection and CSF pleocytosis resolved. Conclusion CSF HIV infection is common across the spectrum of infection and is directly related to CSF pleocytosis, though whether the latter is a response to or a contributing cause of CSF infection remains uncertain. Slowing in the rate of CSF response to ART compared to plasma as CD4 counts decline indicates a changing character of CSF infection with systemic immunological progression. Longer-term responses indicate that CSF infection generally responds well to ART, even in the face of systemic virological failure due to drug resistance. We present simple models to explain the differing relationships of CSF to plasma HIV in these settings.

    Full Text Available Plasmacytoid dendritic cells (pDC provide an important link between innate and acquired immunity, mediating their action mainly through IFN-alpha production. pDC suppress HIV-1 replication, but there is increasing evidence suggesting they may also contribute to the increased levels of cell apoptosis and pan-immune activation associated with disease progression. Although having the same clinical spectrum, HIV-2 infection is characterized by a strikingly lower viremia and a much slower rate of CD4 decline and AIDS progression than HIV-1, irrespective of disease stage. We report here a similar marked reduction in circulating pDC levels in untreated HIV-1 and HIV-2 infections in association with CD4 depletion and T cell activation, in spite of the undetectable viremia found in the majority of HIV-2 patients. Moreover, the same overexpression of CD86 and PD-L1 on circulating pDC was found in both infections irrespective of disease stage or viremia status. Our observation that pDC depletion occurs in HIV-2 infected patients with undetectable viremia indicates that mechanisms other than direct viral infection determine the pDC depletion during persistent infections. However, viremia was associated with an impairment of IFN-alpha production on a per pDC basis upon TLR9 stimulation. These data support the possibility that diminished function in vitro may relate to prior activation by HIV virions in vivo, in agreement with our finding of higher expression levels of the IFN-alpha inducible gene, MxA, in HIV-1 than in HIV-2 individuals. Importantly, serum IFN-alpha levels were not elevated in HIV-2 infected individuals. In conclusion, our data in this unique natural model of "attenuated" HIV immunodeficiency contribute to the understanding of pDC biology in HIV/AIDS pathogenesis, showing that in the absence of detectable viremia a major depletion of circulating pDC in association with a relatively preserved IFN-alpha production does occur.

    Introduction HIV-related stigma impacts the quality of life and care management of HIV-infected and HIV-affected individuals, but how we measure stigma and its impact on children and adolescents has less often been described. Methods We conducted a systematic review of studies that measured HIV-related stigma with a quantitative tool in paediatric HIV-infected and HIV-affected populations. Results and discussion Varying measures have been used to assess stigma in paediatric populations, with most studies utilizing the full or variant form of the HIV Stigma Scale that has been validated in adult populations and utilized with paediatric populations in Africa, Asia and the United States. Other common measures included the Perceived Public Stigma Against Children Affected by HIV, primarily utilized and validated in China. Few studies implored item validation techniques with the population of interest, although scales were used in a different cultural context from the origin of the scale. Conclusions Many stigma measures have been used to assess HIV stigma in paediatric populations, globally, but few have implored methods for cultural adaptation and content validity. PMID:27717409

    Compared with high infection areas of the world, the total HIV infection rate in China is relatively low. Nonetheless,because of China's vast territory and large population, the potential infection risk must be taken seriously. In the next few years, needle sharing among injection drug users will remain the most common route of transmission for the HIV/AIDS epidemic in China. Unprotected sex is gradually becoming a major route of transmission. China began to implement HAART in 1999 according to international standards. Prior to 2003, there were only about 150 HIV/AIDS patients were treated with HAART in some clinical trials and about 100 HIV/AIDS patients were treated by private sources.Results of those treatments are the scientific basis for development of the therapeutic strategies in China. In March of 2003, the Chinese government initiated China CARES program. In November of 2003, the Chinese Ministry of Health announced a national policy of free ARV treatment to all HIV+ Chinese citizens who were in poverty and required ARV therapy. There are total of 19,456 HIV/AIDS patients received free ARV drugs to date in 159 regions and 441 towns.Current challenges are how to follow-up and evaluate those patients in the clinical settings. The longer the therapy is postponed, the more side effects and the higher probability of drug resistance are going to occur. It remains unclear,therefore, when HAART regimen should be started in the HIV/AIDS population in China.

    Substance users are at increased risk for HIV and HCV infection. Still, many substance use treatment programs (SUTP) fail to offer HIV/HCV testing. The present secondary analysis of screening data from a multi-site randomized trial of rapid HIV testing examines self-reported HIV/HCV testing patterns and serostatus of 2473 SUTP patients in 12 community-based sites that had not previously offered on-site testing. Results indicate that most respondents screened for the randomized trial tested more than a year prior to intake for HIV (52 %) and HCV (38 %). Prevalence rates were 3.6 and 30 % for HIV and HCV, respectively. The majority of participants that were HIV (52.2 %) and HCV-positive (40.5 %) reported having been diagnosed within the last 1-5 years. Multivariable logistic regression showed that members of high-risk groups were more likely to have tested. Bundled HIV/HCV testing and linkage to care issues are recommended for expanding testing in community-based SUTP settings.

    Neurological complications in opioid abusing Human Immunodeficiency Virus-1 (HIV-1) patients suggest enhanced neurodegeneration as compared to non-drug abusing HIV-1 infected population. Neural precursor cells (NPCs), the multipotent cells of the mammalian brain, are susceptible to HIV-1 infection and as opiates also perturb their growth kinetics, detailed mechanistic studies for their co-morbid exposure are highly warranted. Using a well characterized in vitro model of human fetal brain-derived neural precursor cells, we investigated alterations in NPC properties at both acute and chronic durations. Chronic morphine and Tat treatment attenuated proliferation in NPCs, with cells stalled at G1-phase of the cell cycle. Furthermore HIV-Tat and morphine exposure increased activation of extracellular signal-regulated kinase-1/2 (ERK1/2), enhanced levels of p53 and p21, and decreased cyclin D1 and Akt levels in NPCs. Regulated by ERK1/2 and p53, p21 was found to be indispensible for Tat and morphine mediated cell cycle arrest. Our study elaborates on the cellular and molecular machinery in NPCs and provides significant mechanistic details into HIV-drug abuse co-morbidity that may have far reaching clinical consequences both in pediatric as well as adult neuroAIDS.

    Full Text Available BACKGROUND: In the generalized epidemics of HIV in southern Sub-Saharan Africa, men who have sex with men have been largely excluded from HIV surveillance and research. Epidemiologic data for MSM in southern Africa are among the sparsest globally, and HIV risk among these men has yet to be characterized in the majority of countries. METHODOLOGY: A cross-sectional anonymous probe of 537 men recruited with non-probability sampling among men who reported ever having had sex with another man in Malawi, Namibia, and Botswana using a structured survey instrument and HIV screening with the OraQuick(c rapid test kit. PRINCIPAL FINDINGS: The HIV prevalence among those between the ages of 18 and 23 was 8.3% (20/241; 20.0% (42/210 among those 24-29; and 35.7% (30/84 among those older than 30 for an overall prevalence of 17.4% (95% CI 14.4-20.8. In multivariate logistic regressions, being older than 25 (aOR 4.0, 95% CI 2.0-8.0, and not always wearing condoms during sex (aOR 2.6, 95% CI 1.3-4.9 were significantly associated with being HIV-positive. Sexual concurrency was common with 16.6% having ongoing concurrent stable relationships with a man and a woman and 53.7% had both male and female sexual partners in proceeding 6 months. Unprotected anal intercourse was common and the use of petroleum-based lubricants was also common when using condoms. Human rights abuses, including blackmail and denial of housing and health care was prevalent with 42.1% (222/527 reporting at least one abuse. CONCLUSIONS: MSM are a high-risk group for HIV infection and human rights abuses in Malawi, Namibia, and Botswana. Concurrency of sexual partnerships with partners of both genders may play important roles in HIV spread in these populations. Further epidemiologic and evaluative research is needed to assess the contribution of MSM to southern Africa's HIV epidemics and how best to mitigate this. These countries should initiate and adequately fund evidence-based and targeted HIV

    Infection with Candida species remains a major problem in HIV infected patients. The analysis of over 15,000 hospitalisations (1985-2007) in the AVK cohort shows an increasing incidence of non-albicans species in candida esophagitis. Although our analysis shows a decreasing incidence of opportunistic infections like PCP, cerebral toxoplasmosis and others since the introduction of highly active antiretroviral therapy the incidence of candida esophagitis remains as high as in the years before the HAART era. This observation might reflect the development of resistance against fluconazole and the selection of non-albicans species as a consequence of a long-term prophylactic treatment of HIV+ patients over years.

    Full Text Available There is growing evidence of a significant burden of human papillomavirus (HPV infection and associated disease in men. High rates of HPV infection have been observed in men from sub-Saharan Africa where HIV prevalence is high. HIV infection increases HPV prevalence, incidence and persistence and is strongly associated with the development of anogenital warts and anal, penile and head and neck cancers in men. Despite increasing access to antiretroviral therapy, there appears to be little benefit in preventing the development of these cancers in HIV-positive men, making prevention of infection a priority. New prevention options that are being introduced in many African countries include male circumcision and HPV vaccination. However, more data are needed on the burden of HPV disease in men before boys are included in HPV vaccination programmes.

    A 36-year-old HIV-positive man presented with symptoms of redness, blurred vision and foreign body sensation in his right eye for 3 months. The slit lamp examination revealed deep stromal infiltration with a feathery margin in an otherwise minimal anterior chamber reaction. A corneal scraping was negative. Confocal microscopy demonstrated an abnormal large hyper-reflective oval shape in the corneal stroma. Corneal infiltration did not show improvement after topical, intrastromal and intracameral antifungal treatment. Therapeutic penetrating keratoplasty was performed to eradicate the infection. Corneal button culture and histopathological results confirmed the diagnosis of Penicillium marneffei keratitis. No recurrent infection occurred after corneal transplantation. This appears to be the first report of P. marneffei keratitis in an HIV-infected patient. Although it is an uncommon condition, it should be one of the differential diagnoses in an HIV-infected patient presenting with keratitis. PMID:27535731

    We report on a late-preterm neonate with severe congenital cytomegalovirus (CMV) infection, refractory to antiviral therapy with ganciclovir. Subsequent immune diagnostics led to the finding of HIV infection at day 69, even though the mother tested negative for HIV in early pregnancy. Thus, in congenital CMV infection, HIV testing should be performed to elucidate maternal HIV seroconversion during late pregnancy. Our case strongly supports third trimester screening of HIV infection acquired during pregnancy, yet recommended only for women with traditional risk factors for HIV or living in an area of high HIV prevalence.

    Full Text Available While the consensus is that HIV prevalence has remained low among adolescent offenders, the prevalence of STDs and HIV transmission risk behaviors is alarming, particularly for those abusing alcohol and other drugs and those displaying antisocial or conduct disorder characteristics. In the current study, 269 male and 110 female inner city, culturally diverse alcohol and other drug (AOD abusing adolescent offenders completed measures of (a psychopathy, using the Millon Adolescent Clinical Inventory (MACI (b HIV transmission risk behavior, (c prevention skills and attitudes and (d social desirability. Results showed that those with high levels of psychopathy reported more AOD use, overall unprotected sex and more sexual activity when influenced by alcohol and/or marijuana. High psychopathy adolescent offenders also reported lower self-efficacy and sexual response-efficacy, less favorable safer sex and condom attitudes and less favorable intentions to engage in safer sex behaviors, when controlling for social desirability. Data suggest that adolescent offenders, who are either in court-ordered treatment or detention, should be assessed for psychopathy and provided with tailored risk reduction interventions, geared toward attitudinal and behavioral change. A discussion of integrating neurobiological measures to improve the next generation of tailored interventions for this risk group is offered in conclusion.

    HIV testing constitutes an important strategy to control the HIV epidemic, which therefore merits an observation of HIV testing practices to help improve testing effectiveness. In 2008, a cross-sectional survey among recently diagnosed (≤ 3 years) HIV-infected patients was conducted in Belgium, Estonia, Finland and Portugal. Participants were questioned about reasons for HIV testing, testing place and testing conditions. Univariate and multivariate analyses were performed. Out of 1460 eligible participants, 629 (43%) were included. Forty-one per cent were diagnosed late and 55% had never undergone a previous HIV test with perceived low risk being the primary reason for not having been tested earlier. Heterogeneity in HIV testing practices was observed across countries. Overall, tests were most frequently conducted in primary care (38%) and specialised clinics (21%), primarily on the initiative of the health care provider (65%). Sixty-one per cent were tested with informed consent, 31% received pretest counselling, 78% received post-test counselling, 71% were involved in partner notification and 92% were in care three months after diagnosis. The results showed that HIV testing is done in a variety of settings suggesting that multiple pathways to HIV testing are provided. HIV testing practice is being normalised, with less focus on pretest counselling, yet with emphasis on post-test follow-up. Major barriers to testing are centred on the denial of risk. Efforts are needed to concurrently promote public awareness about HIV risk and benefits of HIV testing and train clinicians to be more proactive in offering HIV testing. PMID:24090396

    Full Text Available Abstract. Tuberculous meningitis (TBM is a devastating disease. TBM occurs more commonly in HIV infected patients. The influence of HIV co-infection on clinical manifestations and outcome of TBM is not well defined. Yet, some differences have been observed and stroke has been recorded to occur more frequently. This study reports on an HIV infected Caucasian female with lung, meningeal tuberculosis and stroke due to a cortical sub-cortical ischemic lesion.TBM was documented in the absence of neurologic symptoms. At the same time, miliary lung TB caused by multi-susceptible Mycobacterium tuberculosis was diagnosed. Anti-TB therapy consisting of a combination of four drugs was administered. The patient improved and was discharged five weeks later. In conclusion, TBM and multiple underling pathologies including HIV infection, as well as other risk factors can lead to a greater risk of stroke. Moreover, drug interactions and their side effects add levels of complexity. TBM must be included in the differential diagnosis of HIV infected patients with stroke and TBM treatment needs be started as soon as possible before the onset of vasculopathy.

    2012-01-01

    HIV infection and antiretroviral therapy each appear to increase cardiovascular disease risk. Increased risk may be attributable to the inflammatory effects of HIV infection and dyslipidemia associated with some antiretroviral agents. The prevalence of cardiovascular disease is increasing as patients live longer, age, and acquire traditional coronary heart disease (CHD) risk factors. In general, any additional cardiovascular risk posed by HIV infection or antiretroviral therapy is of potential concern for patients who are already at moderate or high risk for CHD. Long-term and well-designed studies are needed to more accurately ascertain to what degree HIV infection and antiretroviral therapy affect long-term cardiovascular disease risk. Management of dyslipidemia to reduce CHD risk in HIV-infected patients is much the same as in the general population, with the cornerstone consisting of statin therapy and lifestyle interventions. Smoking cessation is a major step in reducing CHD risk in those who smoke. This article summarizes a presentation by James H. Stein, MD, at the IAS-USA live continuing medical education activity held in New York City in March 2012.

    Anti-retroviral drugs suppress HIV-1 plasma viremia to undetectable levels; however, latent HIV-1 persists in reservoirs within HIV-1-infected patients. The silent provirus can be activated through the use of drugs, including protein kinase C activators and histone deacetylase inhibitors. This "shock" approach is then followed by "kill" of the producing cells either through direct HIV-1-induced cell death or natural immune mechanisms. However, these mechanisms are relatively slow and effectiveness is unclear. Here, we develop an approach to specifically target and kill cells that are activated early in the process of virus production. We utilize a novel nanocapsule technology whereby the ricin A chain is encapsulated in an inactive form within a polymer shell. Specificity for release of the ricin A toxin is conferred by peptide crosslinkers that are sensitive to cleavage by HIV-1 protease. By using well-established latent infection models, J-Lat and U1 cells, we demonstrate that only within an HIV-1-producing cell expressing functional HIV-1 protease will the nanocapsule release its ricin A cargo, shutting down viral and cellular protein synthesis, and ultimately leading to rapid death of the producer cell. Thus, we provide proof of principle for a novel technology to kill HIV-1-producing cells without effects on non-target cells.

    Of eight human herpesviruses (HHVs), often, only herpes simplex virus types 1 (HSV-1) and 2 (HSV-2) find mention in medical literature as both of these viruses are commonly associated with genital lesions and oral ulcers, commonly known as cold sores. However, role of human herpesviruses as copathogens and in aggravation and in the transmission of other human diseases, especially the Acquired immunodeficiency syndrome (HIV/AIDS) has only very recently been recognized. Therefore, screening and treating subclinical HHV infections may offer slowing of HIV infection, disease progression, and its transmission. Beside HSV-1 and HSV-2, HHV-3 a causative agent of herpes zoster remained one of the first manifestations of HIV disease before the era of highly active antiretroviral therapy (HAART). HHV-5 also known as human Cytomegalovirus infection remains a significant risk factor for HIV-associated mortality and morbidity even in HAART era. It is proposed that Cytomegalovirus viremia could be a better predictor of HIV disease progression than CD4+ T-lymphocyte count. The role of HHV-4 or Epstein-Burr virus and HHV-6, HHV-7, and HHV-8 is still being investigated in HIV disease progression. This review provides insight into the current understanding about these 8 HHVs, their co-pathogenesis, and role in HIV/AIDS disease progression. The review also covers recent literature in favor and against administering anti-HHV treatment along with HAART for slower AIDS progression and interrupted sexual transmission. PMID:27013807

    Full Text Available Abstract Background Surgical site infection (SSI are the third most frequently reported nosocomial infection, and the most common on surgical wards. HIV-infected patients may increase the possibility of developing SSI after surgery. There are few reported date on incidence and the preventive measures of SSI in HIV-infected patients. This study was to determine the incidence and the associated risk factors for SSI in HIV-infected patients. And we also explored the preventive measures. Methods A retrospective study of SSI was conducted in 242 HIV-infected patients including 17 patients who combined with hemophilia from October 2008 to September 2011 in Shanghai Public Health Clinical Center. SSI were classified according to Centers for Disease Control and Prevention (CDC criteria and identified by bedside surveillance and post-discharge follow-up. Data were analyzed using SPSS 16.0 statistical software (SPSS Inc., Chicago, IL. Results The SSI incidence rate was 47.5% (115 of 242; 38.4% incisional SSIs, 5.4% deep incisional SSIs and 3.7% organ/space SSIs. The SSI incidence rate was 37.9% in HIV-infected patients undergoing abdominal operation. Patients undergoing abdominal surgery with lower preoperative CD4 counts were more likely to develop SSIs. The incidence increased from 2.6% in clean wounds to 100% in dirty wounds. In the HIV-infected patients combined with hemophilia, the mean preoperative albumin and postoperative hemoglobin were found significantly lower than those in no-SSIs group (P Conclusions SSI is frequent in HIV-infected patients. And suitable perioperative management may decrease the SSIs incidence rate of HIV-infected patients.

    Full Text Available In high income nations, traumatic life experiences such as childhood sexual abuse are much more common in people living with HIV/AIDS (PLWHA than the general population, and trauma is associated with worse current health and functioning. Virtually no data exist on the prevalence or consequences of trauma for PLWHA in low income nations.We recruited four cohorts of Tanzanian patients in established medical care for HIV infection (n = 228, individuals newly testing positive for HIV (n = 267, individuals testing negative for HIV at the same sites (n = 182, and a random sample of community-dwelling adults (n = 249. We assessed lifetime prevalence of traumatic experiences, recent stressful life events, and current mental health and health-related physical functioning. Those with established HIV infection reported a greater number of childhood and lifetime traumatic experiences (2.1 and 3.0 respectively than the community cohort (1.8 and 2.3. Those with established HIV infection reported greater post-traumatic stress disorder (PTSD symptomatology and worse current health-related physical functioning. Each additional lifetime traumatic experience was associated with increased PTSD symptomatology and worse functioning.This study is the first to our knowledge in an HIV population from a low income nation to report the prevalence of a range of potentially traumatic life experiences compared to a matched community sample and to show that trauma history is associated with poorer health-related physical functioning. Our findings underscore the importance of considering psychosocial characteristics when planning to meet the health needs of PLWHA in low income countries.

    Full Text Available Objective: HIV can affect CNS in early stages of disease and determine neurological impairment. HBV DNA was found in CSF of HIV co-infected patients, but little is known about the neurotropic character of this virus. Here we assessed the degree of association between HBV infection and neurological impairment in a large cohort of long-term survivors, HIV-infected patients that experienced multiple therapeutic schemes over time. Methods: A total of 462 HIV-1-infected patients were retrospectively followed up for 10 years for HBV infection and neurological impairment. The patients were tested for immune (flow cytometry and virological parameters of HIV infection (Roche Amplicor, version 1.5/ COBAS AmpliPrep/COBAS TaqMan HIV-1 test and for HBV infection markers (HBsAg, anti HBc: Murex Biotech ELISA tests. Many of these patients have experienced between one and six regimens such as: 2 NRTIs, 3 NRTIs, 2 NRTIs+1 NNRTI, 1 NRTI+1 NNRTI+1 PI, 2 NRTIs+2 PIs. Results: After 10 years 29.87% of the patients presented neurological impairment. Out of them 56.52% were HBV-infected. The prevalence of HIV encephalopathy (HE in our studied cohort was 22.7% and 50.4% of these patients were HBV-infected. The median HIV diagnosis age was 7 and the median age of HE diagnosis was 10. In order to establish a possible correlation between HBV infection and HE we first reviewed and excluded the main risk factors associated with HE at the moment of diagnosis: low weight, anemia, constitutional symptoms, low CD4+count, high plasma HIV-RNA load. No patient was infected with HCV. The groups of patients that presented HE and HBsAg and HE without HBsAg were balanced regarding sex, number of deceased patients, number of class C3 patients, but the patients in first group presented lower CD4 values at HE diagnosis vs patients from second group 2: 44.5 vs 95 cells/µL, p=0.3; lower nadir CD4 count: 38 vs 51 cell/µL, p=0.1; and slightly higher HIV viral load: 5.2 vs 5 log10 copies

    There are numerous case reports on psychoses in AIDS patients and, although more seldom, also in HIV-positive patients in early stages of infection; however, systematic investigations on the frequency, e.g., relevant for the indication of an HIV test in psychiatric patients, are missing. For this study, 1046 HIV-positive patients were examined regarding psychoses. A total of 301 patients (28.8%) were HIV-positive but asymptomatic, and 380 patients (36.2%) had the lymphadenopathy syndrome. One hundred thirty-two patients (12.6%) suffered from an AIDS-related complex and 233 patients (22.3%) from AIDS. Of these 1046 patients, only 9 (0.9%) suffered from psychoses. One patient with a paranoid-hallucinatory syndrome was asymptomatic; one in the lymphadenopathy syndrome was manic. The other 7 patients were all in late stages of the infection. A causal relationship between HIV infection and psychosis and probable in only 3 patients. These data do not indicate a markedly elevated prevalence of psychosis in HIV-positive or AIDS patients.

    HIV partner disclosure may facilitate social support, improve psychological well-being among HIV-infected individuals, and promote HIV testing and HIV prevention among their sexual partners. A growing literature emphasizes the critical role of interpersonal factors may play in decision-making and practice regarding HIV partner disclosure. However, there is a dearth of empirical studies that investigate how interpersonal factors may be associated with HIV partner disclosure. Using cross-sectional data collected from 791 HIV-infected people in Guangxi China, we examined the associations between these two interpersonal factors (quality of relationship with partner and family communication) and HIV partner disclosure. Descriptive analysis, t-test analysis, and gender stratified GLM analysis were conducted. We find that disclosing HIV status to partners was significantly related to better quality of relationship with partners and open and effective family communication. Gender and partner HIV status might moderate the associations between interpersonal factors and HIV partner disclosure. Our findings suggest the importance of considering relationship quality and enhancing open and comfortable family communication in HIV disclosure interventions. Gender difference and partner HIV status should be also considered in HIV disclosure intervention to address the diverse needs of HIV-infected people.

    The demographics of the HIV-infected population in the United States have shifted in a way that few would have predicted 30 years ago when the tide of sick and dying patients largely consisted of young men. Effective ART has allowed those infected to live long, productive lives and to grow old with their disease. With the increase in life expectancy afforded by HIV treatment, the cause of death among HIV-infected individuals is far more likely to be from an HIV-associated non-AIDS condition. Nonetheless, HIV seems to accelerate the aging process, and care providers involved in the treatment of older patients with HIV need to be aware that their patients are at increased risk of developing various common disorders, compared to uninfected same-age patients. Clinicians need to remain vigilant to the possibility of a new diagnosis of HIV among their older patients. Awareness of current or distant risk, frank discussions of sexual practices, and willingness to offer routine testing are crucial to making this diagnosis, with the recognition that longevity for patients with HIV is directly linked to how soon they enter care. HIV infection adds another challenge to the management of older patients; geriatricians and HIV specialists need to coordinate their efforts to provide patients with comprehensive multidisciplinary care. Older patients with HIV also have social and psychological needs that extend beyond the medical office. Maintaining independence, acknowledging limitations, reducing risk of adverse events such as falls or medication errors, and supporting self-acceptance and awareness are only a few of the many areas where care providers outside the medical office can be important for patients' ongoing well-being. Accessing family support, community outreach, church affiliation, or other outpatient support networks can be useful for patients. The remarkable change in prognosis brought about by effective ART in the mid-1990s has meant that HIV is now, for many, a

    Marburg virus, the Kaposi's sarcoma-associated herpesvirus (KSHV) and Dengue virus all activate, and benefit from, expression of the transcription regulator nuclear erythroid 2-related factor 2 (Nrf2). The impact of Nrf2 activation on human immunodeficiency virus (HIV) infection has not been tested. Sulforaphane (SFN), produced in cruciferous vegetables after mechanical damage, mobilizes Nrf2 to potently reprogram cellular gene expression. Here we show for the first time that SFN blocks HIV infection in primary macrophages but not in primary T cells. Similarly SFN blocks infection in PMA-differentiated promonocytic cell lines, but not in other cell lines tested. siRNA-mediated depletion of Nrf2 boosted HIV infectivity in primary macrophages and reduced the anti-viral effects of SFN treatment. This supports a model in which anti-viral activity is mediated through Nrf2 after it is mobilized by SFN. We further found that, like the type I interferon-induced cellular anti-viral proteins SAMHD1 and MX2, SFN treatment blocks infection after entry, but before formation of 2-LTR circles. Interestingly however, neither SAMHD1 nor MX2 were upregulated. This shows for the first time that Nrf2 action can potently block HIV infection and highlights a novel way to trigger this inhibition.

    The introduction of highly active antiretroviral therapy has proven highly effective in treating patients with HIV/AIDS. However, the high cost of the advanced antiretroviral therapy has led to increased financial constraints on both patients and payers. From business firms'perspective, especially those with operations in developing countries, it is crucial to determine the long-term economic cost implications of alternative employment and benefit policies for HIV-infected workers or those at high risk for the disease. A simulation model is developed to predict the comprehensive lifetime economic costs of HIV-infected workers to an employer. This model employs age,CD4(+) cell counts,and plasma HIV-1 RNA level as major predictors of the disease progression and patient survival in the determination of various cost functions. Major cost components considered include direct expenses on health insurance premium,life insurance premium, short-term disability benefits, long-term disability benefits, hiring/training expenses, and indirect costs resulting from reduced or lost productivity at work. An individual model and a group model are derived to estimate the costs of an individual and a group of HIV-infected patients, respectively. Over a 10-year period, following the nonadvanced antiretroviral treatment regimen, the group model predicts that the total lifetime cost of an HIV-infected worker can be as high as U.S. 90,000 dollars to his/her employer, of which 60,000 dollars would be various explicit costs and 30,000 dollars lost work productivity. Sensitivity analysis further demonstrated that changes in the initial level of age,CD4(+) cell count, HIV-1 RNA viral load,CD4(+) cell decline rate, and the costs of medical care influence the dynamics of the cost functions. HIV infection can result in sizable economic costs to an employer over the lifetime course of an infected employee if not treated with the advanced antiretroviral therapy. These cost estimates provide a

    2014-08-01

    Ever since HIV was first diagnosed in human, a great number of scientific works have been undertaken to explore the biological mechanisms involved in the infection and progression of the disease. Several cellular automata (CA) models have been introduced to gain insights into the dynamics of the disease progression but none of them has taken into account effects of certain immune cells such as the dendritic cells (DCs) and the CD8+ T lymphocytes (CD8+ T cells). In this work, we present a CA model, which incorporates effects of the HIV specific immune response focusing on the cell-mediated immunities, and investigate the interaction between the host immune response and the HIV infected cells in the lymph nodes. The aim of our work is to propose a model more realistic than the one in Precharattana et al. (2010) [10], by incorporating roles of the DCs, the CD4+ T cells, and the CD8+ T cells into the model so that it would reproduce the HIV infection dynamics during the primary phase of HIV infection.

  9. Predictors of impaired HDL function in HIV-1 infected compared to uninfected individuals

    In recent years we face an increase in the aging of the HIV-1-infected population, which is not only due to effective antiretroviral therapy but also to new infections among older people. Even with the use of the antiretroviral therapy, HIV-associated neurocognitive disorders represent an increasing problem as the HIV-1-infected population ages. Increased amyloid beta (Aβ) deposition is characteristic of HIV-1-infected brains, and it has been hypothesized that brain vascular dysfunction contr...

    Vertical exposure to HIV occurs at a time when functional capacity of the infant’s immune system is attenuated through immaturity. Immune response capability is rooted in host genetic makeup, and the broad and fine specificity of innate and adaptive immune responses, respectively, shape the outcomes of HIV encounter in some instances and imprint viral changes through selective immune pressure in others. Findings from recent studies have profound implications for understanding immune pathogene...

    Over 100 HIV-infected patients have initiated chronic dialysis at San Francisco General Hospital (SFGH) since 1985. This study employed retrospective analysis to identify determinants of and trends in survival among HIV-infected patients who have initiated chronic dialysis at SFGH from January 1, 1985 to November 1, 2002 (n = 115). Cohort patient survival was compared with survival after an AIDS-opportunistic illness in all HIV-infected patients in San Francisco during the study period. Higher CD4 count (hazard ratio [HR], 0.86 per 50 cells/mm(3) increase; 95% confidence interval [CI], 0.80 to 0.93) and serum albumin (HR, 0.53 per 1 g/dl increase; CI, 0.36 to 0.78) at initiation of dialysis were strongly associated with lower mortality. Survival for those initiating dialysis during the era of highly active antiretroviral therapy (HAART) was 16.1 mo versus 9.4 mo for those initiating dialysis before this time, but this difference was not statistically significant. In adjusted analysis, only a non-statistically significant trend toward improved survival during the HAART era was noted (HR, 0.59; CI, 0.34 to 1.04). By comparison, survival for all HIV-infected patients after an AIDS-opportunistic illness in San Francisco increased from 16 mo in 1994 to 81 mo in 1996. The dramatic improvement in survival that has occurred since the mid-1990s for patients with HIV appears to be greatly attenuated in the sub-group undergoing dialysis. Although this may partly reflect confounding by race, injection drug use and HCV co-infection, future attempts to improve survival among HIV-infected dialysis patients should focus on barriers to the effective use of HAART in this group.

    Skeletal muscle mitochondrial dysfunction may contribute to low aerobic capacity. We previously reported 40% lower aerobic capacity in HIV-infected men compared to noninfected age-matched men. The objective of this study was to compare skeletal muscle mitochondrial enzyme activities in HIV-infected men on antiretroviral therapy (55 ± 1 years of age, n = 10 African American men) with age-matched controls (55 ± 1 years of age, n = 8 Caucasian men), and determine their relationship with aerobic capacity. Activity assays for mitochondrial function including enzymes involved in fatty acid activation and oxidation, and oxidative phosphorylation, were performed in homogenates prepared from vastus lateralis muscle. Hydrogen peroxide (H2O2), cardiolipin, and oxidized cardiolipin were also measured. β-hydroxy acyl-CoA dehydrogenase (β-HAD) (38%) and citrate synthase (77%) activities were significantly lower, and H2O2 (1.4-fold) and oxidized cardiolipin (1.8-fold) were significantly higher in HIV-infected men. VO2peak (mL/kg FFM/min) was 33% lower in HIV-infected men and was directly related to β-HAD and citrate synthase activity and inversely related to H2O2 and oxidized cardiolipin. Older HIV-infected men have reduced oxidative enzyme activity and increased oxidative stress compared to age-matched controls. Further research is crucial to determine whether an increase in aerobic capacity by exercise training will be sufficient to restore mitochondrial function in older HIV-infected individuals.

    Fabrizi, Fabrizio; Martin, Paul; Messa, Piergiorgio

    2013-01-01

    Infections with blood-borne pathogens are still common among patients on maintenance dialysis all over the world. The control of infection due to blood-borne viruses (particularly HBV) within dialysis units has been a major goal in the management of patients with chronic kidney disease in the industrialized world. Standard precautions and specific procedures have been recommended to prevent infections with HBV, HCV and HIV within dialysis units. Isolation of HBsAg positive patients by dialysis rooms, staff and machines continues to be an important step to control HBV infection within dialysis units, according to the CDC and other regulatory agencies. Some prospective observational studies have reported the complete prevention of HCV transmission to hemodialysis patients in the absence of any isolation policy, and the use of dedicated dialysis machines for HCV-infected patients is not recommended by clinical guidelines. Isolation of HCV-infected patients should be considered in special circumstances only. Vaccination is an important tool against transmission of HBV among patients on long-term dialysis even if the immune response towards the hepatitis B vaccine remains unsatisfactory. Hemodialysis is considered a low risk setting for the transmission of human immunodeficiency virus (HIV) infection, providing that standard and specific procedures are carefully observed. HIV-infected patients do not have to be isolated from other patients or dialyzed separately on dedicated machines.

    2008-05-01

    Full Text Available Background & objectives: The present study was designed to determine possible contributory impact of malaria infection on some biochemical markers in subjects with HIV co-infection in order to know if they are adverse or protective.Methods: Participants were recruited at the Voluntary Counseling and Testing Unit, Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria and grouped into: (i Malaria and HIV co-infection group (n = 45; and (ii HIV infected group without concurrent malaria infection (n = 57. Standard laboratory methods were used for the HIV and Plasmodium falciparum antigen screening, malaria parasite density, CD4+ T-cell count, packed cell volume, white blood cell count, serum iron and albumin concentrations.Results: The results showed that serum iron and albumin were significantly reduced and raised respectively in ‘Malaria–HIV co-infection group’ compared with ‘HIV infection group’ (p <0.05 and p <0.05. A positive association was observed between age and serum iron concentration in malaria and HIV co-infected group (r = 0.580; p <0.05 while negative associations were observed between PCV and serum iron (r = – 0.388; p <0.05 and between CD4+ T-cells and serum iron concentration (r = – 0.362; p<0.05 in malaria and HIV co-infected group. The CD4+ T-cell count, WBC count, PCV were not significantly different between the Malaria-HIV co-infection group and HIV infection group.Interpretation & conclusion: In the present study serum iron and albumin concentrations were the most sensitive indicators that showed the contributory impact of malaria infection on biochemical index in HIV co-infected subjects. The findings suggest that at the defined stage of HIV infection in the present study, malaria co-infection may moderate the impact of HIV infection on iron metabolism and hepatic synthesis of albumin.

    Objective To investigate the anti-HIV effects of ampelopsin and its interaction with HIV-1 coreceptor CXCR4. Methods Through anti-virus experiments in vitro, the inhibitory effect of ampelopsin on HIV-1 infection was verified. Chemotaxis assay was performed to show the ability to induce PBMCs migration by ampelopsin, RANTES and SDF-1(. Fluorescence labelling monoclonal antibody was utilized to observe the interaction of ampelopsin and CXCR4. Mice immunosuppressant model was also established to detail the role ampelopsin played in regulating cellular immunological functions. Results Ampelopsin could protect sensitive cells against HIV-1 infection and dramatically reduce HIV-1 antigen P24 expression. HIV-1SF33 attaching to MT-4 cells was interfered by ampelopsin, and the EC50 was 0.175 mg/mL for cellular protection and 0.024 mg/mL for P24 inhibition. At co-cultivating phase, EC50 was 0.229 mg/mL and 0.197 mg/mL respectively. Furthermore, the EC50 was 0.179 mg/mL and 0.348 mg/mL in acute infection. Human PBMCs migration was induced after being challenged with ampelopsin or chemokines, and synergistic action was observed during co-treatment. Ampelopsin alone resulted in maximal chemotaxis at 1 mg/mL. HIV-1 co-receptor CXCR4 on the surface of PBMCs was decreased by internalization, which indicated the effect of ampelopsin on CXCR4. About 70% CXCR4 was reduced by ampelopsin at 1 mg/mL. Ampelopsin also augmented cellular immunological functions in immunosuppressive mice. Conclusion Ampelopsin displays a strong inhibitive role during HIV-1 absorption, incubation and acute infection. These results are coincident with its immune enhancement.

    Full Text Available HIV serodiscordant couples represent at least half of all HIV-affected couples worldwide. Many of these couples have childbearing desires. Safer methods of conception may allow for pregnancy while minimizing the risk of sexual transmission of HIV. In serodiscordant partnerships with an HIV-infected female and HIV-uninfected male, vaginal insemination of a partner's semen during the fertile period coupled with 100% condom use may be the safest method of conception.

  5. Differentially-Expressed Pseudogenes in HIV-1 Infection

    Directory of Open Access Journals (Sweden)

    Aditi Gupta

    2015-09-01

    Full Text Available Not all pseudogenes are transcriptionally silent as previously thought. Pseudogene transcripts, although not translated, contribute to the non-coding RNA pool of the cell that regulates the expression of other genes. Pseudogene transcripts can also directly compete with the parent gene transcripts for mRNA stability and other cell factors, modulating their expression levels. Tissue-specific and cancer-specific differential expression of these “functional” pseudogenes has been reported. To ascertain potential pseudogene:gene interactions in HIV-1 infection, we analyzed transcriptomes from infected and uninfected T-cells and found that 21 pseudogenes are differentially expressed in HIV-1 infection. This is interesting because parent genes of one-third of these differentially-expressed pseudogenes are implicated in HIV-1 life cycle, and parent genes of half of these pseudogenes are involved in different viral infections. Our bioinformatics analysis identifies candidate pseudogene:gene interactions that may be of significance in HIV-1 infection. Experimental validation of these interactions would establish that retroviruses exploit this newly-discovered layer of host gene expression regulation for their own benefit.

    During the last 20 years at least 23 cases of motor neuron disease have been reported in HIV-1 seropositive patients. In this report we describe the clinical picture of a young man with HIV-1 clade C infection and flail arm-like syndrome, who we were able to follow-up for a long period. We investigated and prospectively monitored a 34-year-old man with features of flail arm syndrome, who developed the weakness and wasting 1 year after being diagnosed with HIV-1 infection after a routine blood test. He presented in 2003 with progressive, symmetrical wasting and weakness of the proximal muscles of the upper limb of 2 years' duration. He had severe wasting and weakness of the shoulder and arm muscles. There were no pyramidal signs. He has been on HAART for the last 4 years and the weakness or wasting has not worsened. At the last follow-up in July 2007, the patient had the same neurological deficit and no other symptoms or signs of HIV-1 infection. MRI of the spinal cord in 2007 showed characteristic T2 hyperintense signals in the central part of the spinal cord, corresponding to the central gray matter. Thus, our patient had HIV-1 clade C infection associated with a ‘flail arm–like syndrome.’ The causal relationship between HIV-1 infection and amyotrophic lateral sclerosis (ALS)-like syndrome is still uncertain. The syndrome usually manifests as a lower motor neuron syndrome, as was seen in our young patient. It is known that treatment with antiretroviral therapy (ART) stabilizes/improves the condition. In our patient the weakness and atrophy remained stable over a period of 3.5 years after commencing HAART regimen. PMID:20142861

    Liver disease in HIV-infected patients has remained unaddressed in India. This study describes the causes of liver disease in HIV-infected patients and short-term outcome in them. Designed as a prospective observational study, it was conducted at Jawaharlal Institute of Postgraduate Medical Education and Research between September 2011 and March 2013. All consecutive HIV patients (>13 years) attending the antiretroviral therapy clinic or admitted in the Medicine Department were screened, and patients with liver disease or with either HBsAg or anti-HCV antibody positivity were included in the study. Of the 198 patients screened, 51 (26 %) had either abnormal liver function test or had HBsAg or anti-HCV positivity. The median age of the patients was 40 years and 82 % were males. The median CD4 count was 123 cells/mm(3). Eighteen (35 %) of them had alcoholic liver disease. Six patients had probable hepatic involvement due to tuberculosis. Ten patients had antituberculosis drug-induced hepatotoxicity. One patient had acute hepatitis B and seven patients had chronic hepatitis B. The cause could not be established in 10 patients (20 %). After a median period of 8 months of follow up, 23 patients had improved, 19 patients (37 %) had died, and six patients had been lost to follow up. Of the patients who had died, 11 patients (58 %) had tuberculosis, and 6 patients (30 %) had decompensated alcoholic liver disease. In conclusion, liver disease in HIV-infected patients was associated with high mortality. Alcohol abuse, tuberculosis, and antituberculosis drugs were the major causes. PMID:27435618

    Objectives To assess the prevalence of sexually transmitted infections (STIs), frequency of sexual risk behaviors, and relationship between knowledge of HIV infection status and sexual risk behavior among HIV-infected men who have sex with men (MSM) attending an STI clinic in Peru. Methods We recruited a convenience sample of 559 MSM from a municipal STI clinic in Lima, Peru. Participants completed a survey and provided blood for HIV, Syphilis, and HSV-2 antibody testing, and urine for gonorrhea and chlamydia nucleic acid testing. Results Among 124 HIV-infected MSM, 72.6% were aware of their HIV-infected status. Active syphilis (RPR≥1:8) was diagnosed in 21.0% of HIV-infected participants, HSV-2 in 79.8%, urethral gonorrhea in 1.6%, and chlamydia in 1.6%. Among 41 participants reporting insertive anal intercourse with their last sex partner, 34.2% did not use a condom. Of 86 participants reporting receptive anal intercourse, 25.6% did not use a condom. At least one episode of insertive unprotected anal intercourse (UAI) with an HIV-uninfected partner during the previous six months was reported by 33.6% (35/104) of participants, and receptive UAI with an HIV-uninfected partner by 44.6% (45/101). No difference in frequency of UAI, with HIV-uninfected or HIV-infected partners, was observed between men who knew their serostatus compared with those who were previously undiagnosed (all p-values >0.05). Conclusions HIV-infected MSM in Peru engaged in high-risk behaviors for spreading HIV and STIs. Knowledge of HIV-infected status was not associated with a decreased frequency of unprotected anal intercourse. Additional efforts to reduce risk behavior after the diagnosis of HIV infection are necessary. PMID:19028945

    Full Text Available A 38-year-old man had a 1-week history of right lower quadrant abdominal pain; the initial impression was that he had diverticulitis of the ascending colon with an intra-abdominal abscess. Signs of peritonitis mandated an immediate right hemicolectomy. The unusual location of the abscess and the patient’s unusual postoperative course suggested that he might also have a systemic disease. Testing for HIV infection was positive. After 2 weeks in hospital, he was treated as an outpatient for both tuberculosis and HIV with a favourable outcome. In Taiwan a pre-operative HIV test is not performed routinely, and the HIV seroprevalence in surgical patient populations is unknown. Surgeons should keep the possibility of HIV infection in mind in a patient with an unusual clinical course.

    Studies have shown that human immunodeficiency virus type 2 (HIV-2) is less pathogenic than HIV-1, with a lower rate of disease progression. Similarly, plasma viral loads are lower in HIV-2 infection, suggesting that HIV-2 replication is restricted in vivo in comparison to that of HIV-1. However, to date, in vivo studies characterizing replication intermediates in the viral life cycle of HIV-2 have been limited. In order to test the hypothesis that HIV-2 has a lower replication rate in vivo t...

  15. Laboratory diagnosis of HIV infection in Papua New Guinea.

    Science.gov (United States)

    Babona, D V; Slama, G; Puiahi, E

    1996-09-01

    In Papua New Guinea, the laboratory diagnosis of HIV infection is based on proof of HIV antibody in the patient's serum. Under the government scheme, the testing is done in 30 laboratories, including the Papua New Guinea HIV Reference Laboratory (NRL), the Red Cross Blood Transfusion Service in Port Moresby, and 19 provincial and 9 district laboratories. An alternative testing strategy was adopted in 1993 based on a WHO recommendation, replacing the classical testing strategy (enzyme immunoassay + Western blot). The alternative testing strategy uses several EIA, rapid or simple HIV antibody assays for the detection and confirmation of the HIV antibody. This approach is faster and cheaper, with the same sensitivity and specificity as the classical testing algorithm. Except for the NRL, the Serodia Fujirebio HIV-1 gelatin particle agglutination assay is used throughout the country as the screening test. The PNG National HIV Reference Laboratory is the only laboratory authorized to perform confirmatory testing and to release positive results. Therefore, all serum samples reactive in the screening assay are sent to the NRL for confirmation by the battery of EIA, rapid or simple assays in accordance with the alternative testing strategy adopted. The paper explains the alternative testing strategy and highlights the principle of each individual test that is employed.

    While Human Immunodeficiency Virus (HIV) infections are reducing in incidence with the advent of Highly Active Anti-retroviral Therapy (HAART), there remain a number of challenges including the existence of reservoirs, drug resistance and anatomical barriers to antiretroviral therapy. To overcome these, smart nanoparticles with stimuli responsive release are proposed for delivery of anti-retroviral agents. The paper highlights the strategic similarities between the design of smart antiretroviral nanocarriers and those optimized for cancer chemotherapy. This includes the development of nanoparticles capable of passive and active targeting as well as those that are responsive to various internal and external triggers. For antiretroviral therapy, the relevant triggers for stimuli responsive release of drugs include semen, enzymes, endosomal escape, temperature and magnetic field. Deriving from the experience of cancer chemotherapy, additional potential triggers are light and ultrasound which remain hitherto unexplored in HIV therapy. In addition, the roles of nanomicrobicides (nanogels) and virus mimetic nanoparticles are discussed from the point of view of prevention of HIV transmission. The challenges associated with translation of smart nanoparticles for HIV infections to realize the Millennium Development Goal of combating HIV infections are discussed.

    2012-01-01

    Dyslipidemia is common in patients with human immunodeficiency virus (HIV) and may result in significant morbidity, including coronary heart disease (CHD). Treatment of dyslipidemia in these patients is generally based on the National Cholesterol Education Program Adult Treatment Panel III goals for individuals without HIV. For individuals with ≥ 2 cardiovascular risk factors, the risk of CHD should be evaluated using the Framingham risk calculator and managed accordingly. Switching to an antiretroviral regimen with a favorable lipid profile should be considered before pharmacologic management if virologic suppression can be maintained. Statins are the first-choice therapy for elevated low-density lipoprotein cholesterol, but in HIV-infected individuals, special consideration must be given to drug-drug interactions, specifically those between protease inhibitors and statins. Management of dyslipidemia in HIV-infected individuals is a challenging but important aspect of chronic disease management. Additional research, specifically related to the role of chronic inflammation, is needed to better define the relationship between HIV infection and cardiovascular disease.

    Full Text Available Background. The CDC recommends persons at high-risk for HIV infection in the United States receive annual HIV testing to foster early HIV diagnosis and timely linkage to health care. Heterosexuals make up a significant proportion of incident HIV infections (>25%, but test for HIV less frequently than those in other risk categories. Yet factors that promote or impede annual HIV testing among heterosexuals are poorly understood. The present study examines individual/attitudinal-, social-, and structural-level factors associated with past-year HIV testing among heterosexuals at high-risk for HIV. Methods. Participants were African American/Black and Hispanic heterosexual adults (N=2307 residing in an urban area with both high poverty and HIV prevalence rates. Participants were recruited by respondent-driven sampling (RDS in 2012-2015 and completed a computerized structured assessment battery covering background factors, multi-level putative facilitators of HIV testing, and HIV testing history. Separate logistic regression analysis for males and females identified factors associated with past-year HIV testing.Results. Participants were mostly male (58%, African American/Black (75%, and 39 years old on average (SD = 12.06 years. Lifetime homelessness (54% and incarceration (62% were common. Half reported past-year HIV testing (50% and 37% engaged in regular, annual HIV testing. Facilitators of HIV testing common to both genders included sexually transmitted infection (STI testing or STI diagnosis, peer norms supporting HIV testing, and HIV testing access. Among women, access to general medical care and extreme poverty further predicted HIV testing, while recent drug use reduced the odds of past-year HIV testing. Among men, past-year HIV testing was also associated with lifetime incarceration and substance use treatment.Conclusions. The present study identified gaps in rates of HIV testing among heterosexuals at high-risk for HIV, and both common and

    Loneliness is common in persons living with HIV (PLWH). Lonely people smoke at higher rates than the general population, and loneliness is a likely contributor to the ongoing smoking epidemic among PLWH. We explored factors associated with loneliness in a cohort of 272 PLWH smokers enrolled in two separate tobacco treatment trials. Loneliness was independently associated with lack of a spouse or partner, lower educational attainment, "other or unknown" HIV exposure category, depression, anxiety, recent alcohol consumption, and higher daily cigarette consumption. Referral to group therapy reduced loneliness, whereas referral to an individual web-based tobacco treatment did not.

    Full Text Available Opportunistic fungal infections can cause significant morbidity and mortality in immunocompromised patients. We describe a paediatric case of an unusual disseminated fungal infection. A three-year-old HIV-infected child with severe immunosuppression (CD4+ T-cell count 12 × 106 /L was admitted to hospital with pneumonia, gastroenteritis and herpes gingivostomatitis. Despite antibacterial and antiviral therapy, he experienced high fevers and developed an erythematous maculopapular rash and abdominal tenderness. The child’s condition progressively worsened during the admission. A thermally dimorphic fungus was cultured from bone marrow and identified as an Emmonsia species on DNA sequencing. The patient made a good recovery on amphotericin B deoxycholate and antiretroviral therapy. Itraconazole was continued for a minimum of 12 months, allowing for immune reconstitution to occur. This case is the first documented description of disseminated disease caused by a novel Emmonsia species in an HIV-infected child in South Africa.

    International Nuclear Information System (INIS)

    We investigated the association between pulse wave velocity (PWV) and HIV infection, antiretroviral treatment-related characteristics, viral load, immune status, and metabolic changes in a cross-sectional study nested in a cohort of HIV/AIDS patients who have been followed for metabolic and cardiovascular changes since 2007. The study included patients recruited from the cohort (N = 261) and a comparison group (N = 82) of uninfected individuals, all enrolled from April to November 2009. Aortic stiffness was estimated using the carotid-femoral PWV (Complior-Artech, Paris, France). The groups were similar with respect to age, metabolic syndrome, diabetes mellitus, Framingham score, and use of antihypertensive and hypolipidemic medications. Hypertension was more frequent among the controls. Individuals with HIV had higher triglyceride, glucose and HDL cholesterol levels. Among individuals with HIV/AIDS, those with a nadir CD4+ T-cell count <200 cells/mm3 had a higher PWV (P = 0.01). There was no statistically significant difference when subjects were stratified by gender. Heart rate, age, male gender, and blood pressure were independently correlated with PWV. Nadir CD4+ T-cell count did not remain in the final model. There was no significance difference in PWV between HIV-infected individuals and uninfected controls. PWV was correlated with age, gender, and blood pressure across the entire population and among those infected with HIV.

  12. Rapid Development of Advanced Liver Fibrosis after Acquisition of Hepatitis C Infection during Primary HIV Infection

    2009-01-01

    Abstract We report the first reported case of a 61-year-old MSM who was diagnosed with syphilis, primary HIV infection, and acute hepatitis C (HCV) within the same time period who rapidly developed significant liver fibrosis within 6 months of acquisition of both infections. It has been well described that individuals with primary HIV infection have an increase in activated CD8+ T cells, which causes a state of immune activation as was evident in this patient. Acquisition of HCV during this time could have further skewed this response resulting in massive hepatocyte destruction, inflammation, and subsequent liver fibrosis. Recent literature suggest that MSM with primary HIV infection have higher rates of acquisition of HCV than other HIV-positive cohorts and HCV acquisition can occur very soon after acquiring HIV. This case of rapid hepatic fibrosis progression coupled with the increasing incidence of HCV in individuals with primary HIV infection demonstrates a need for this phenomenon to be studied more extensively.

    2011-04-01

    Traditional medicines are an integral part of health care worldwide, even though their efficacy has not been scientifically proven. HIV-infected individuals may use them singularly or in combination with conventional medicines. Many in vitro studies have proven the anti-HIV, anti-Candida, and anti-herpes simplex virus potential of traditional plants and identified some of the mechanisms of action. Very few in vivo studies are available that involve a small number of participants and show controversial results. In addition, knowledge is limited of the role of traditional medicines in the enhancement of the immune system. The use of traditional medicines with antiretroviral drugs (ARVs) has created a problem because drug interactions compromise the efficacy of ARVs. Several currently popular plants have been studied in the laboratory for their interaction with ARVs, with disadvantageous results. Unfortunately, no clinical trials are available. The science of traditional medicines is relatively new and is at present being modernized worldwide. However, there are still ethical issues regarding traditional medicines that need to be addressed-for example, regulations regarding quality control and standardization of medicines, regulation and education of healers who deliver these medicines, and unregulated clinical trials. The workshop addressed the following questions about traditional medicine and their use in HIV infection: What are the mechanisms of action of anti-HIV traditional medicines? Should traditional medicines be used in conjunction with ARV? Do traditional medicines enhance the immune system? Should medicinal plants be used for the control of oral infections associated with HIV? What are the ethical issues surrounding the use of traditional medicines for the treatment of HIV and associated infections?

    The dramatic change of the natural history of HIV-infected patients by highly active antiretroviral therapy (HAART) has exposed these patients to cardiovascular risk, including cardiovascular disease and hypertension. In HIV-infected patients, the development of arterial hypertension, at least in the medium-long term is an established feature, although recognized predictors of its development have not been clearly identified. In addition, conflicting data regarding the influence of antiretroviral therapy (ART) are reported. The presence of a proinflammatory state and oxidative stress-mediated endothelial dysfunction seem, however, to play a pathophysiologic role. In this review, we examine and provide a comprehensive, literature based, consideration of the pathophysiologic aspects of hypertension in these patients. HIV-infected patients, independently of the presence of hypertension, remain at very high cardiovascular risk due to the presence of the same cardiovascular risk factors recognized for the general population with, in addition, the indirect influence of the ART, essentially via its effect on lipid metabolism. This review based on the evidence from the literature, concludes that the management of HIV-infected patients in terms of cardiovascular prevention emerges as a priority. The consideration of cardiovascular risk in these patients should receive the same emphasis given for the general population at high cardiovascular risk, including adequate blood pressure control according to international guidelines.

  19. Bone health in children and adolescents with perinatal HIV infection

    2013-06-01

    Full Text Available The long-term impact on bone health of lifelong HIV infection and prolonged ART in growing and developing children is not yet known. Measures of bone health in youth must be interpreted in the context of expected developmental and physiologic changes in bone mass, size, density and strength that occur from fetal through adult life. Low bone mineral density (BMD appears to be common in perinatally HIV-infected youth, especially outside of high-income settings, but data are limited and interpretation complicated by the need for better pediatric norms. The potential negative effects of tenofovir on BMD and bone mass accrual are of particular concern as this drug may be used more widely in younger children. Emphasizing good nutrition, calcium and vitamin D sufficiency, weight-bearing exercise and avoidance of alcohol and smoking are effective and available approaches to maintain and improve bone health in all settings. More data are needed to inform therapies and monitoring for HIV-infected youth with proven bone fragility. While very limited data suggest lack of marked increase in fracture risk for youth with perinatal HIV infection, the looming concern for these children is that they may fail to attain their expected peak bone mass in early adulthood which could increase their risk for fractures and osteoporosis later in adulthood.

    Full Text Available INTRODUCTION: AIDS was first recognized in United States in the summer of 1981, when the U.S. Centers for disease control and prevention (CDC reported the unexplained occurrence of pneumocystis jiroveci pneumonia in five previously healthy homosexual men in LA and Kaposi’s sarcoma with or without P. jiroveci pneumonia in 26 previously healthy homosexual men in NY and LA. The disease was soon recognized in male and female injection drug users, in hemophiliacs and blood transfusion recipients; among female sexual partners of men with AIDS; among infants born to mothers with AIDS or with history of injection drug use. A clinician should view HIV disease as a spectrum ranging from primary infection, with or without the acute syndrome, to the asymptomatic stage, to advanced stages associated with opportunistic diseases. CASE PRESENTATION: We present an unusual case of Parkinsonism secondary to HIV infection. A 36years old female had been diagnosed with HIV, after one and a half years she subsequently developed Parkinsonism features. CONCLUSION: In the wake of numerous opportunistic infections and other diseases associated with HIV infection it is important to recognize Parkinsonism early and initiate treatment for improving the quality of life of the patient.

    To ensure their survival, microbial pathogens have evolved diverse strategies to subvert host immune defenses. The human retrovirus HIV-1 has been proposed to hijack the natural endocytic function of dendritic cells (DCs) to infect interacting CD4 T cells in a process termed trans-infection.

    In order to offer a gene therapy-based treatment against AIDS, it is likely to be necessary to harvest and culture CD4 cells from HIV-positive patients without activating the HIV infection. We have used a magnetic cell sorting (MACS) system to enrich CD4 cells. Using positive selection, CD4 cells...... from a total of 14 patients were enriched from a mean percentage of CD4 cells in PBMC of 18% to 91% CD4 cells in the enriched cell fraction. Furthermore, we found that this separation did not lead to an increase in viral load. The MACS performed equally well on cells from HIV-positive patients and HIV......-negative donors. CD4 cells from HIV-positive patients were readily expanded with PHA; 19-fold by day 10, 50-fold by day 20, and 156-fold by day 25. However, CD4 cells from HIV-positive patients grew at a slower rate than CD4 cells from HIV-negative donors. The expanded CD4 cells showed a high degree of CD4...

    Full Text Available Disseminated Mycobacterium avium complex (MAC infection is an important AIDS-defining opportunistic infection. The introduction of antimicrobial prophylaxis and antiretroviral therapy (ART markedly reduced the incidence of disseminated MAC infection and improved the survival of affected individuals. However, it seems that patients with new or recurrent MAC infection are still encountered in clinical practice. Our images captured the characteristic endoscopic findings of MAC duodenitis. The gastrointestinal (GI tract appears to be a common port of entry for MAC infection in patients with AIDS. Early recognition of GI MAC infection by endoscopy in HIV-infected patients and initiation of anti-MAC therapy and ART may reduce morbidity and mortality.

    Advances in the management of HIV infection have resulted in a growing population of older adults living with HIV. Both aging and HIV infection have been independently associated with central nervous system changes and corresponding declines in neurocognitive functioning. Poorer semantic verbal fluency output is also common in both HIV infection and healthy older adults, although, the possible additive effects of these risk factors are unknown. The present study aimed to examine the combined ...

    Human immunodeficiency virus type 1 (HIV-1) disease is associated with aberrant immune activation, and coinfection with hepatitis C virus (HCV) exacerbates hepatic inflammation and fibrosis. However, the role of HIV-1 infection or host immune modulation in liver pathogenesis is not clearly defined. Here, we report that regulatory T (Treg) cells prevent liver immunopathogenesis during HIV-1 infection in a humanized mouse model. In the absence of Treg cells, HIV-1 infection induced liver fibros...

    HIV infection and substance use disorders are chronic diseases with complex contributions to health-related quality of life (HRQOL). We conducted a cross-sectional survey of 951 HIV-infected adults receiving care at 14 HIV Research Network sites in 2003 to estimate associations between HRQOL and specific substance use among HIV-infected patients. HRQOL was assessed by multi-item measures of physical and role functioning, general health, pain, energy, positive affect, anxiety, and depression. ...

    Full Text Available OBJECTIVE: To evaluate treatment adherence among perinatally-infected pediatric human immunodeficiency virus (HIV patients followed in pediatric centers in Brazil. METHODS: This was a cross-sectional multicenter study. Medical records were reviewed and adherence scale, assessment of caregivers' quality of life (WHOQOL-BREF, anxiety, depression, and alcohol/substances use/abuse were assessed. Outcomes included self-reported 100% adherence in the last three days and HIV viral load (VL < 50 copies/mL. Statistical analyses included contingency tables and respective statistics, and multivariable logistic regression. RESULTS: 260 subjects were enrolled: 78% children and 22% adolescents; 93% of caregivers for the children and 77% of adolescents reported 100% adherence; 57% of children and 49% of adolescents had VL < 50 copies/mL. In the univariate analyses, HIV diagnosis for screening due to maternal infection, lower caregiver scores for anxiety, and higher scores in physical and psychological domains of WHOQOL-BREF were associated with 100% adherence. Shorter intervals between pharmacy visits were associated with VL < 50 copies/mL (p ≤ 0.01. Multivariable regression demonstrated that caregivers who did not abuse alcohol/other drugs (OR = 0.49; 95% CI: 0.27-0.89 and median interval between pharmacy visits < 33 days (OR = 0.97; 95% CI: 0.95-0.98 were independently associated with VL < 50 copies/mL; whereas lower caregiver scores for anxiety (OR = 2.57; 95% CI: 1.27-5.19 and children's HIV diagnosis for screening due to maternal infection (OR = 2.25; 95% CI: 1.12-4.50 were found to be independently associated with 100% adherence. CONCLUSIONS: Pediatric HIV programs should perform routine assessment of caregivers' quality of life, and anxiety and depression symptoms. In this setting, pharmacy records are essential to help identify less-than-optimal adherence.

    Full Text Available Abstract Background Toxoplasmosis in immuno-compromised hosts manifests primarily as a life threatening condition, toxoplasmic encephalitis. However, there is scarce information about the magnitude of Toxoplasma gondii infection among HIV-infected people in Ethiopia. This study was, therefore, conducted to determine the sero-prevalence of T. gondii infection among HIV-infected and HIV-uninfected subjects. Findings Sera were collected from people with and without HIV infection for the purpose of studying hepatitis B virus (HBV at St. Paul Hospital, Addis Ababa, Ethiopia from 24 January 2007 to 15 February 2007. Among these sera, the first 330 consecutive sera, 165 from each HIV sero-group, were selected and tested for anti-T. gondii IgG antibodies using Enzyme Linked Immunosorbent Assay. The seroprevalence of Toxoplasma infection was assessed against socio-demographic characteristics, HIV and HBV serostatus and HBV-related risk factors. The overall sero-prevalence of latent T. gondii infection among the study subjects was 90.0%. Toxoplasma infection was observed with respective prevalence of 93.3% and 86.7% among HIV-infected and HIV-uninfected people. Though Toxoplasma infection seems to be influenced by age, gender and HIV serostatus, only HBV serostatus was significantly associated (OR 2.71, CI 1.12 to 6.57 in multivariate logistic regression analysis. Conclusion The seroprevalence of latent T. gondii infection is high and similar by HIV status. Educating people to prevent acquisition of new Toxoplasma infection and minimizing the risk of disease manifestations among HIV-Toxoplasma co-infected individuals is important.

    There were 1,311 newly-diagnosed HIV cases in San Francisco between 2005 and 2011 that were linked to care at publicly-funded facilities and had viral sequences available for analysis. Of the 214 cases characterized as recently-infected with HIV at time of diagnosis, 25% had a recent sexually transmitted infection (STI) diagnosis (vs. 10% among longer-standing HIV infections, p<0.001) and 57% were part of a phylogenetic transmission cluster (vs. 42% among longer-standing HIV infection, p<0.001). The association observed between recent HIV infection and having a STI diagnosis during the interval overlapping likely HIV acquisition points to potential opportunities to interrupt HIV transmission.

    Full Text Available Según la literatura, la osteonecrosis tiene una mayor incidencia en los pacientes infectados con HIV que en la población general. Ello sería resultado de la confluencia de factores de riesgo clásicos y de otros propios de esta población o más prevalentes en ella, como el tratamiento con inhibidores de proteasa, la dislipemia producto de su consumo, la presencia de anticuerpos anticardiolipina séricos, la hipercoagulabilidad, la restauración inmune y las vasculitis. Presentamos una serie de 13 pacientes infectados con HIV con osteonecrosis. El motivo de consulta fue dolor en grandes articulaciones. Cuatro eran alcoholistas, 8 tabaquistas y 9 tenían dislipemia. Once habían recibido esteroides en algún momento de la vida aunque sólo uno estaba recibiéndolos al momento del inicio del dolor. En 2 se detectaron anticuerpos anticardiolipina séricos. Doce tenían sida y recibían tratamiento antirretroviral de alta eficacia (11 con inhibidores de proteasa. Ellos lograron una adecuada recuperación inmunológica. Consideramos necesario incluir la osteonecrosis como diagnóstico diferencial de artralgia persistente en pacientes infectados con HIV e investigar infección por HIV en todo paciente con osteonecrosis sin claros factores predisponentes.Osteonecrosis, also known as avascular necrosis, is chiefly characterized by death of bone caused by vascular compromise. The true incidence of osteonecrosis in HIV-infected patients is not well known and the pathogenesis remains undefined. Hypothetical risk factors peculiar to HIV-infected individuals that might play a role in the pathogenesis of osteonecrosis include the introduction of protease inhibitors and resulting hyperlipidemia, the presence of anticardiolipin antibodies in serum leading to a hypercoagulable state, immune recovery and vasculitis. Hereby we present a series of 13 HIV-infected patients with osteonecrosis. The most common symptom upon presentation was arthralgia. The majority

    Full Text Available HIV is still a major health problem in developing countries. Even though high HIV-risk-taking behaviors have been reported in African fishing villages, local distribution patterns of HIV infection in the communities surrounding these villages have not been thoroughly analyzed. The objective of this study was to investigate the geographical distribution patterns of HIV infection in communities surrounding African fishing villages. In 2011, we applied age- and sex-stratified random sampling to collect 1,957 blood samples from 42,617 individuals registered in the Health and Demographic Surveillance System in Mbita, which is located on the shore of Lake Victoria in western Kenya. We used these samples to evaluate existing antibody detection assays for several infectious diseases, including HIV antibody titers. Based on the results of the assays, we evaluated the prevalence of HIV infection according to sex, age, and altitude of participating households. We also used Kulldorff's spatial scan statistic to test for HIV clustering in the study area. The prevalence of HIV at our study site was 25.3%. Compared with the younger age group (15-19 years, adults aged 30-34 years were 6.71 times more likely to be HIV-positive, and the estimated HIV-positive population among women was 1.43 times larger than among men. Kulldorff's spatial scan statistic detected one marginally significant (P = 0.055 HIV-positive and one significant HIV-negative cluster (P = 0.047 in the study area. These results suggest a homogeneous HIV distribution in the communities surrounding fishing villages. In addition to individual behavior, more complex and diverse factors related to the social and cultural environment can contribute to a homogeneous distribution pattern of HIV infection outside of African fishing villages. To reduce rates of transmission in HIV-endemic areas, HIV prevention and control programs optimized for the local environment need to be developed.

    Introduction Studies on the prevalence of and risk factors for tuberculosis (TB) among newly diagnosed human immunodeficiency virus (HIV)-infected children in sub-Saharan Africa are scarce and in Nigeria there is paucity of reported data. We determined the prevalence of and risk factors for pulmonary TB (PTB) in newly diagnosed (treatment-naïve) HIV-1 infected children at the pediatric HIV clinic of the Jos University Teaching Hospital (JUTH) in Nigeria. Methods We performed a retrospective analysis of 876 children, aged 2 months – 13 years, diagnosed with HIV-1 infection between July 2005 and December 2012, of which 286 were diagnosed with PTB at presentation after TB screening. The study site was the AIDS Prevention Initiative in Nigeria (APIN)-supported Pediatric HIV clinic at JUTH, Jos. A multivariate forward logistic regression modelling was used to identify risk factors for PTB-HIV co-infection. Results The prevalence of PTB-HIV co-infection was 32% (286/876). Severe immunosuppression (SI) and World Health Organization (WHO) HIV clinical stage 3/4 were identified as independent risk factors for PTB-HIV co-infection in HIV infected children. The odds of PTB-HIV co-infection was increased two-fold in HIV-infected children with WHO clinical stage 3/4 compared to those with stage 1/2 (adjusted odds ratio (AOR) 1.76 [1.31-2.37], p<0.001) and 1.5-fold in children with SI compared to those without SI (AOR 1.52 [1.12-2.06], p=0.007). Conclusion In our setting, the burden of PTB was high among newly diagnosed HIV-infected children, and late WHO HIV clinical stage and severe immunosuppression were associated with PTB-HIV co-infection. Therefore there is a clear need to improve strategies for early diagnosis of both HIV and PTB to optimize clinical outcomes. PMID:27019829

    Combined p24 antigen-HIV antibody fourth-generation assays that identify most of the early HIV infections have been used extensively worldwide for several years. This poses challenges for the traditional algorithm of line immunoassay (LIA) confirmation. LIA tests are useful methods with their high specificity and their ability to differentiate HIV-1 from HIV-2, but they are reactive days after the fourth generation enzyme immunoassays. With acute HIV infection, high levels of infectious virus are detectable in serum and genital secretions. The rate of transmission during acute HIV infection is higher than the established HIV infection, for this reason, new HIV testing strategies need to focus on sensitivity, especially for this highly contagious phase immediately after infection. Serum sample of a patient sent to Ege University Hospital Clinical Virology Laboratory was repeatedly reactive with low signal/cutoff ratios with two different commercial fourth generation enzyme immunoassays (Architect HIV Ag/Ab Combo Reagent Kit, Abbott, Germany and Vidas HIV Duo Quick, Biomerieux, France). The sample was non-reactive with the LIA (INNO-LIA HIV I/II Score, Innogenetics, Belgium) and HIV RNA (RealTime HIV-I Amplification Reagent Kit, Abbott, USA) result was positive (4.1 x 10(5) copies/ml). With the presentation of this case, the role of LIA in the diagnosis of early HIV infection and its place in test algorithms were questioned. PMID:23971936

    Full Text Available Background and Objectives: Intestinal parasitic infection is a common entity in patients infected with human immunodeficiency virus (HIV. These infections may lead to fatal complications in the immuno suppressed individuals. The aim of the present study was to determine the prevalence of intestinal parasitic infections in HIV sero-positive patients and their relationship with the immune status of individuals. Materials and Method s: Fecal samples from 100 HIV sero-positive and an equal number of HIV sero-negative individuals were collected and examined for enteric parasites by direct microscopy. CD4 counts were carried out in only HIV sero-positive patients. Prevalence of intestinal parasites in patients with CD4 count 200 cells/μl (P < 0.01. Prevalence of coccidian parasites was significantly (P < 0.01 higher (14% in HIV sero-positive subjects compared with HIV sero-negative subjects (2%. Isospora belli (25% was the most common parasite with CD4 count <200 cells/μl, followed by Cryptosporidium parvum (12.5%. Prevalence of intestinal parasitic infections was significantly higher in patients with diarrhea, 73.6% than without diarrhea, 25.9%, (P < 0.05. The mean CD4 count of HIV sero-positive patients presenting with diarrhea was significantly (P < 0.01 lower (181.26 ± 135.14 than without diarrhea (352.02 ± 204.03. Conclusion: This study emphasizes the need for routine screening of parasites especially in patients with lower CD4 count so as to decrease the morbidity by ensuring the early treatment of the cases.

    Full Text Available BACKGROUND: Co-infection with HIV and HCV is very common. It is estimated that over 5 million people are co-infected with HIV and HCV worldwide. Accumulated evidence shows that each virus alters the course of infection of the other one. CD8+ T cells play a crucial role in the eradication of viruses and infected target cells. To the best of our knowledge, no one has investigated the gene expression profiles in HIV/HCV-co-infected individuals. METHODOLOGY: Genome-wide transcriptomes of CD8+ T cells from HIV/HCV-co-infected or mono-infected treatment-naïve individuals were analyzed by microarray assays. Pairwise comparisons were performed and differentially expressed genes were identified followed by quantitative real-time PCR (qRT-PCR validation. Directed Acyclic Graphs (DAG from Web-based Gene SeT AnaLysis Toolkit (WebGestalt and DAVID bioinformatics resources 6.7 (the Database for Annotation, Visualization, and Integrated Discovery were used to discover the Gene Ontology (GO categories with significantly enriched gene numbers. The enriched Kyoto Encyclopedia of Genes and Genomes (KEGG pathways were also obtained by using WebGestalt software. RESULTS AND CONCLUSIONS: A total of 110, 24 and 72 transcript IDs were shown to be differentially expressed (> 2-fold and p<0.05 in comparisons between HCV- and HIV-mono-infected groups, HIV/HCV-co-infected and HIV-mono-infected groups, and HIV/HCV-co-infected and HCV-mono-infected groups, respectively. In qRT-PCR assay, most of the genes showed similar expressing profiles with the observation in microarray assays. Further analysis revealed that genes involved in cell proliferation, differentiation, transcriptional regulation and cytokine responses were significantly altered. These data offer new insights into HIV/HCV co-infections, and may help to identify new markers for the management and treatment of HIV/HCV co-infections.

    Full Text Available Introduction & Objective: The risk of developing chronic hepatitis B virus (HBV is 5% in general population but can reach up to 20% in HIV patients. The response rate to HBV vaccine in HIV infected patients is 23.8-56 percent. The aim of this study was to evaluate response of HIV-infected patients to 20 µg dose of recombinant HBV vaccine. Materials & Methods: In this quasi experimental study, 51 subjects, sampled through census, were HIV patients who had HBsAg negative test in HIV/AIDS counseling and care center. Patients were vaccinated with 20 µg of recombinant HBV vaccine, IM at intervals of 0, 1 and 6 months. Response to the vaccine was checked 2 months after the last injection. Data were analyzed with SPSS software, using descriptive statistics and nonparametric tests. Results: The mean age of the patients was 33.68±8.37 years. Two patients were female (3.9% and 49 patients were male (96.1%. Mean of hepatitis B antibody level was 47.55±71.58 mIU/ml. The levels of antibody in different patients were as follow: 31 patients (60.8% 10 mIU/ml. There was no significant correlation between antibody levels and CD4+ cell count (correlation coefficient = -0.191. Conclusion: Response to hepatitis B vaccination is low in HIV infected patients. Conventional dose of HBV vaccine is not enough to get protective immunity. Therefore, two-fold dose of vaccine dose, repeat of conventional dose or increasing of interval administration of hepatitis B vaccine should be considered in future studies.

    HIV-1 and HIV-2 have been detected in Cape Verde since 1987, but little is known regarding the genetic diversity of these viruses in this archipelago, located near the West African coast. In this study, we characterized the molecular epidemiology of HIV-1 and HIV-2 and described the occurrence of drug resistance mutations (DRM) among antiretroviral therapy naïve (ARTn) patients and patients under treatment (ARTexp) from different Cape Verde islands. Blood samples, socio-demographic and clinical-laboratory data were obtained from 221 HIV-positive individuals during 2010-2011. Phylogenetic and bootscan analyses of the pol region (1300 bp) were performed for viral subtyping. HIV-1 and HIV-2 DRM were evaluated for ARTn and ARTexp patients using the Stanford HIV Database and HIV-GRADE e.V. Algorithm Homepage, respectively. Among the 221 patients (169 [76.5%] HIV-1, 43 [19.5%] HIV-2 and 9 [4.1%] HIV-1/HIV-2 co-infections), 67% were female. The median ages were 34 (IQR = 1-75) and 47 (IQR = 12-84) for HIV-1 and HIV-2, respectively. HIV-1 infections were due to subtypes G (36.6%), CRF02_AG (30.6%), F1 (9.7%), URFs (10.4%), B (5.2%), CRF05_DF (3.0%), C (2.2%), CRF06_cpx (0.7%), CRF25_cpx (0.7%) and CRF49_cpx (0.7%), whereas all HIV-2 infections belonged to group A. Transmitted DRM (TDRM) was observed in 3.4% (2/58) of ARTn HIV-1-infected patients (1.7% NRTI, 1.7% NNRTI), but not among those with HIV-2. Among ARTexp patients, DRM was observed in 47.8% (33/69) of HIV-1 (37.7% NRTI, 37.7% NNRTI, 7.4% PI, 33.3% for two classes) and 17.6% (3/17) of HIV-2-infections (17.6% NRTI, 11.8% PI, 11.8% both). This study indicates that Cape Verde has a complex and unique HIV-1 molecular epidemiological scenario dominated by HIV-1 subtypes G, CRF02_AG and F1 and HIV-2 subtype A. The occurrence of TDRM and the relatively high level of DRM among treated patients are of concern. Continuous monitoring of patients on ART, including genotyping, are public policies to be implemented

    Given the inordinate burden of HIV illness borne by African American men, investigations of HIV prevention and care in this population are urgently needed. In this qualitative study, a sample of 20 HIV-infected African American men participated in two focus groups in which they exchanged experiences and ideas about living with HIV. They shared details about how they were personally impacted by HIV, and together they constructed a perspective on the larger societal context in which the HIV infection rate among African American men continues unabated. The men focused on growing complacency about HIV/AIDS in the United States, underfunding of supports and services, stigmas operative in African American communities, and differential care based on race, gender, and diagnosis. They saw opportunity in personal strategies that help individual men infected with HIV to take a more empowered stance to deal with the disease and improve their health but looked for changes undertaken by African Americans at the community level to make a real difference in the epidemic. Their vision included enhanced support for HIV prevention and care from influential community institutions like Black churches, more open dialogue about drugs and sexual behavior, and capacity-building for families whose members are HIV-infected or at risk for HIV.

    Full Text Available OBJECTIVE: Characterize intra-individual HIV-1 subtype B pol evolution in antiretroviral naive individuals. DESIGN: Longitudinal cohort study of individuals enrolled during primary infection. METHODS: Eligible individuals were antiretroviral naïve participants enrolled in the cohort from December 1997-December 2005 and having at least two blood samples available with the first one collected within a year of their estimated date of infection. Population-based pol sequences were generated from collected blood samples and analyzed for genetic divergence over time in respect to dual infection status, HLA, CD4 count and viral load. RESULTS: 93 participants were observed for a median of 1.8 years (Mean = 2.2 years, SD =1.9 years. All participants classified as mono-infected had less than 0.7% divergence between any two of their pol sequences using the Tamura-Nei model (TN93, while individuals with dual infection had up to 7.0% divergence. The global substitution rates (substitutions/nucleotide/year for mono and dually infected individuals were significantly different (p<0.001; however, substitution rates were not associated with HLA haplotype, CD4 or viral load. CONCLUSIONS: Even after a maximum of almost 9 years of follow-up, all mono-infected participants had less than 1% divergence between baseline and longitudinal sequences, while participants with dual infection had 10 times greater divergence. These data support the use of HIV-1 pol sequence data to evaluate transmission events, networks and HIV-1 dual infection.

  4. Non-infective pulmonary disease in HIV-positive children

    International Nuclear Information System (INIS)

    It is estimated that over 90% of children infected with human immunodeficiency virus (HIV) live in the developing world and particularly in sub-Saharan Africa. Pulmonary disease is the most common clinical feature of acquired immunodeficiency syndrome (AIDS) in infants and children causing the most morbidity and mortality, and is the primary cause of death in 50% of cases. Children with lung disease are surviving progressively longer because of earlier diagnosis and antiretroviral treatment and, therefore, thoracic manifestations have continued to change and unexpected complications are being encountered. It has been reported that 33% of HIV-positive children have chronic changes on chest radiographs by the age of 4 years. Lymphocytic interstitial pneumonitis is common in the paediatric HIV population and is responsible for 30-40% of pulmonary disease. HIV-positive children also have a higher incidence of pulmonary malignancies, including lymphoma and pulmonary Kaposi sarcoma. Immune reconstitution inflammatory syndrome is seen after highly active antiretroviral treatment. Complications of pulmonary infections, aspiration and rarely interstitial pneumonitis are also seen. This review focuses on the imaging findings of non-infective chronic pulmonary disease. (orig.)

  6. Discrimination against HIV-infected people and the spread of HIV: some evidence from France.

    Directory of Open Access Journals (Sweden)

    Patrick Peretti-Watel

    Full Text Available BACKGROUND: Many people living with HIV/AIDS (PLWHA suffer from stigma and discrimination. There is an ongoing debate, however, about whether stigma, fear and discrimination actually fuel the persisting spread of HIV, or slow it down by reducing contacts between the whole population and high-risk minorities. To contribute to this debate, we analysed the relationship between perceived discrimination and unsafe sex in a large sample of French PLWHAs. METHODOLOGY/PRINCIPAL FINDINGS: In 2003, we conducted a national cross-sectional survey among a random sample of HIV-infected patients. The analysis was restricted to sexually active respondents (N = 2,136. Unsafe sex was defined as sexual intercourse without a condom with a seronegative/unknown serostatus partner during the prior 12 months. Separate analyses were performed for each transmission group (injecting drug use (IDU, homosexual contact, heterosexual contact. Overall, 24% of respondents reported experiences of discrimination in their close social environment (relatives, friends and colleagues and 18% reported unsafe sex during the previous 12 months. Both prevalences were higher in the IDU group (32% for perceived discrimination, 23% for unsafe sex. In multivariate analyses, experience of discrimination in the close social environment was associated with an increase in unsafe sex for both PLWHAs infected through IDU and heterosexual contact (OR = 1.65 and 1.80 respectively. CONCLUSIONS: Our study clearly confirms a relationship between discrimination and unsafe sex among PLWHAs infected through either IDU or heterosexual contact. This relationship was especially strong in the heterosexual group that has become the main vector of HIV transmission in France, and who is the more likely of sexual mixing with the general population. These results seriously question the hypothesis that HIV-stigma has no effect or could even reduce the infection spread of HIV.

    Adherence counseling can improve antiretroviral adherence and related health outcomes in HIV-infected individuals. However, little is known about how much counseling is necessary to achieve clinically significant effects. We investigated antiretroviral adherence and HIV viral load relative to the number of hours of adherence counseling received by 60 HIV-infected drug users participating in a trial of directly observed antiretroviral therapy delivered in methadone clinics. Our adherence couns...

    The widespread access to antiretroviral treatment during the past decades has transformed HIV infection from a lethal disease to a chronic condition, in which the relative burden of non-AIDS-related chronic disorders such as cardiovascular disease, malignancy, renal, liver, and bone disease has...... increased. The adjusted relative risk for myocardial infarction is reported to be around 2-fold compared to that of the general population, which over time is likely to translate into increased absolute risk in an aging population. Thus, delineating potentially HIV-specific pathogenetic mechanisms...

    BACKGROUND: We aimed to investigate whether the insulin precursors, intact (IP) and 32-33 split proinsulin (SP), which are elevated in states of insulin resistance and predict type 2 diabetes, would be elevated in human immunodeficiency virus (HIV)-infected patients with lipodystrophy (LIPO.......01), but did not differ between study groups. CONCLUSIONS: Proinsulin appeared to be increased in HIV-lipodystrophy, but no more than caused by the increased ISR. Nevertheless, the inverse correlations between SP/insulin ratio versus Si(RD) and incremental total proinsulin/insulin ratio versus DI may argue...

  12. Knowledge about aids/HIV infection among female college students

    International Nuclear Information System (INIS)

    Objective: To determine the level of awareness about HIV/ AIDs infection among female college students of Lahore. Results: Ninety-five percent students had heard about HIV/AIDS and its presence in Pakistan, 61.7 % students knew that HIV/AIDS is caused by germs and 91.2% knew about its transmissibility. Over 70% of students knew that HIV can be transmitted through sexual contact, infected blood transfusion, and re-use of infected injection needles. Moreover, only 19.2% mentioned ear/nose piercing with infected needles while 46.8% mentioned breast-feeding as sources of transmission of HIV/AIDS. However, 57% were of the view that second hand clothing cannot spread AIDS. Individuals having multiple sexual partners (78.2%), drug addicts (38.8%), homosexuals (39.2%), commercial sex workers (52.2%) and health care workers (16.2%) were identified as high-risk groups. Only 33.2% student perceived that women are at higher risk of acquiring HIV as compared to men. Regarding prevention of AIDS, 61.0% mentioned avoiding promiscuous sex, 49.3% knew use of condoms and 60.2% were aware that AIDS can be prevented by avoiding homosexuality. Sixty-eight percent and 70.2% students respectively held the view that avoiding used needles for injections in hospitals and laboratories for screening blood or blood products can prevent AIDS, while 78.2% and 55.8% respectively knew that there is no cure or vaccine available for AIDS. Majority of the students (71.5%) have discussed AIDS with their friends while discussion with siblings, parents and teachers was not common. Conclusion: The general level of awareness regarding HIV/AIDS transmission and prevention was satisfactory among college girls included in the study. However, a number of misconceptions and myths like getting HIV/AIDS through nose/ear piercing, its relation to Islam, and use of second hand clothing need to be clarified. (author)

    Editors' Summary Background. For people in sub-Saharan Africa, insufficient food for their daily needs and infection with the human immunodeficiency virus (HIV; the cause of acquired immunodeficiency syndrome or AIDS) are inextricably linked and major causes of illness and death. By reducing the number of healthy adults in the region, HIV/AIDS has decreased food production so fewer people have secure access to sufficient food for a healthy life—many are subject to “food insecurity.” Because g...

    Research assessing whether major depressive disorders (MDD) impacts neurocognitive functions in HIV+ persons has yielded inconsistent results. However, none have considered the role of MDD remission, chronicity, and stability on treatment. Ninety-five HIV+ adults clinically stable on combined antiretroviral treatment completed a psychiatric interview, a depression scale, a neuropsychological, daily living, and cognitive complaints assessments at baseline and 18 months. Participants were screened for current (within 12 months of study entry) alcohol and/or substance use disorder. History of alcohol and/or substance abuse disorder prior to the 12 months entry screen and MDD treatments were recorded. Participants were grouped into two psychiatric nomenclatures: (1) lifetime: no MD episode (MDE), single MDE life-event treated and fully remitted, chronic MDD treated and stable, chronic MDD treated and unstable, and baseline untreated MDE; (2) recent: last 2 years MDE (yes or no). We found that lifetime and recent psychiatric history were more strongly associated with decreased in independence in daily living and cognitive complaints than with baseline neuropsychological performance. However, lack of full remission, instability on treatment in chronic MDD, and severity of symptoms in current MDE were factors in whether MDD impacted baseline neuropsychological performance. Depressive symptoms improved at follow-up in those with baseline moderate-severe symptoms, and MDD was not associated with neurocognitive change at 18 months. A history of alcohol and/or substance abuse disorder was significantly more frequent in those with treated and unstable chronic MDD but it was not associated with neuropsychological performance. MDD recurrence, chronicity profiles, and associated comorbidities are keys factors to understand any potential impact on neurocognitive abilities in HIV infection. More comprehensive consideration of these complex effects could serve at constructively
