    The authors' goal was to study the potential effect on cognitive function of an interaction of HIV infection and a history of alcohol abuse. The subjects were 30 HIV-negative and 50 HIV-positive men with and without a past history of alcohol abuse. Thirty-three of the men (12 HIV negative and 21 HIV positive) had a past history of alcohol abuse, and 47 (18 HIV negative and 29 HIV positive) had never abused alcohol. Each subject's history of alcohol use was obtained by using a syndromal approach based on the Structured Clinical Interview for DSM-III-R and a quantitative approach. Each subject was given a battery of neuropsychological tests assessing verbal reasoning, reaction time, intelligence, memory, and dexterity. The subjects were then compared on a summary neuropsychological impairment rating. There were no significant differences in CD4 level, age, education, depression, anxiety, or other drug abuse history between the HIV-positive and HIV-negative groups with and without a history of alcohol abuse. Significant effects on cognitive function were found for past alcohol abuse and HIV infection, with significant interactions in verbal reasoning, auditory processing, and reaction time. This demonstrates that HIV infection and a history of alcohol abuse have independent effects on some aspects of higher cognitive function but may have synergistic effects on other cognitive domains. In the HIV-negative subjects there were no differences in cognitive function between subjects with and without a history of alcohol abuse. Among the HIV-positive subjects, those with a history of alcohol abuse performed more poorly on tests of verbal IQ, verbal reasoning, and reaction time. There are both additive and interactive effects of previous alcohol abuse and HIV infection on cognition. Individuals with a history of past alcohol abuse may be at greater risk for cognitive dysfunction in the context of HIV 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.

    Background HIV infection and drugs of abuse such as methamphetamine (METH), cocaine, and alcohol use have been identified as risk factors for triggering inflammation. Acute phase proteins such as C-reactive protein (CRP) and serum amyloid A (SAA) are the biomarkers of inflammation. Hence, the interactive effect of drugs of abuse with acute phase proteins in HIV-positive subjects was investigated. Methods Plasma samples were utilized from 75 subjects with METH use, cocaine use, alcohol use, an...

    In many individuals, drug abuse is intimately linked with HIV-1 infection. In addition to being associated with one-third of all HIV-1 infections in the United States, drug abuse also plays a role in disease progression and severity in HIV-1-infected patients, including adverse effects on the central nervous system (CNS). Specific systems within the brain are known to be damaged in HIV-1-infected individuals and this damage is similar to that observed in drug abuse. Even in the era of anti-retroviral therapy (ART), CNS pathogenesis occurs with HIV-1 infection, with a broad range of cognitive impairment observed, collectively referred to as HIV-1-associated neurocognitive disorders (HAND). A number of HIV-1 proteins (Tat, gp120, Nef, Vpr) have been implicated in the etiology of pathogenesis and disease as a result of the biologic activity of the extracellular form of each of the proteins in a number of tissues, including the CNS, even in ART-suppressed patients. In this review, we have made Tat the center of attention for a number of reasons. First, it has been shown to be synthesized and secreted by HIV-1-infected cells in the CNS, despite the most effective suppression therapies available to date. Second, Tat has been shown to alter the functions of several host factors, disrupting the molecular and biochemical balance of numerous pathways contributing to cellular toxicity, dysfunction, and death. In addition, the advantages and disadvantages of ART suppression with regard to controlling the genesis and progression of neurocognitive impairment are currently under debate in the field and are yet to be fully determined. In this review, we discuss the individual and concerted contributions of HIV-1 Tat, drug abuse, and ART with respect to damage in the CNS, and how these factors contribute to the development of HAND in HIV-1-infected patients.

    Hispanics are disproportionately affected by substance abuse, HIV infection, intimate partner violence, and mental health conditions. To address health disparities among Hispanics and other vulnerable groups, it is necessary to understand the complex interactions between health conditions clustering together (e.g., substance abuse, intimate partner violence, and HIV) and the social ecology in which these conditions exist. A syndemic orientation, a consideration of clustering epidemics and common individual, relationship, cultural, and socioenvironmental factors linking these conditions, may be helpful in developing comprehensive models that expand our ability to understand and address health disparities. The purpose of this paper is to introduce a Syndemic Model of Substance Abuse, Intimate Partner Violence, HIV Infection, and Mental Health among Hispanics, and provide evidence from the research literature to support the central relationships and risk and protective factors (i.e., potential links between conditions) depicted by the model. The development and evaluation of interventions aimed at the prevention of substance abuse, intimate partner violence, HIV/AIDS, and mental health problems as a syndemic affecting Hispanics is urgently needed. Public health nurses can initiate this endeavor with the guidance of a Syndemic Model. © 2011 Wiley Periodicals, Inc.

    Background Previous studies have found high rates of childhood sexual abuse (CSA) among US men who have sex with men (MSM). CSA history has been associated with a variety of negative effects later in life including behaviors that place MSM at greater risk for HIV acquisition and transmission. The present analysis is the first to examine the longitudinal association between CSA and HIV infection, unprotected anal sex, and serodiscordant unprotected anal sex, as well as mediators of these relationships among a large sample of HIV-uninfected MSM. Methods The EXPLORE Study was a behavioral intervention trial conducted in 6 US cities over 48 months with HIV infection as the primary efficacy outcome. Behavioral assessments were done every 6 months via confidential computerized assessments. Longitudinal regression models were constructed, adjusting for randomization arm, geographical location of study site, age at enrollment, education, and race/ethnicity. Results Of the 4295 participants enrolled, 39.7% had a history of CSA. Participants with a history of CSA [adjusted hazards ratio = 1.30, 95% confidence interval (CI): 1.02 to 1.69] were at increased risk for HIV infection over study follow-up. A significant association was seen between history of CSA and unprotected anal sex (adjusted odds ratio = 1.24, 95% CI: 1.12 to 1.36) and serodiscordant unprotected anal sex (adjusted odds ratio = 1.30, 95% CI: 1.18 to 1.43). Among participants reporting CSA, the EXPLORE intervention had no effect in reducing HIV infection rates. Participants reporting CSA were significantly more likely to have symptoms of depression and use nonprescription drugs. Conclusions A predictive relationship between a history of CSA and subsequent HIV infection was observed among this large sample of HIV-uninfected MSM. Findings indicate that HIV-uninfected MSM with CSA histories are at greater risk for HIV infection, report higher rates of HIV sexual risk behavior, and may derive less benefit from

    HIV-infected individuals with substance use disorders have a high prevalence of medical and psychiatric morbidities that complicate treatment. Incarceration further disrupts healthcare access and utilization. Without appropriate diagnosis and treatment, drug relapse upon release exceeds 85 %, which contributes to poor health outcomes. A prospective cohort of 1,032 HIV-infected jail detainees were surveyed in a ten-site demonstration project during incarceration and six-months post-release, in order to examine the effect of predisposing factors, enabling resources and need factors on their subsequent drug use. Homelessness, pre-incarceration cocaine and opioid use, and high drug and alcohol severity were significantly associated with cocaine and opioid relapse. Substance abuse treatment, though poorly defined, did not influence post-release cocaine and opioid use. An approach that integrates multiple services, simultaneously using evidence-based substance abuse, psychiatric care, and social services is needed to improve healthcare outcomes for HIV-infected persons transitioning from jails to the community.

    2013-01-01

    Childhood sexual abuse (CSA) is a serious public health issue. Women with HIV who have a history of CSA are at increased risk for sporadic medical treatment, nonadherence to HIV medications, and HIV risk behaviors. These associations pose a challenge to providing health care for this population and are complicated by the possible psychological sequelae of CSA, such as anxiety, depression, dissociation, and posttraumatic stress disorder. This article reviews the effects of CSA on the health status of women with HIV, barriers to treatment adherence, suggested components of trauma-sensitive medical care, and mental health approaches. A trauma-informed, trauma-sensitive care model that addresses barriers associated with health care for women with a history of CSA is suggested. Specific recommendations are offered for the provision of effective clinical care for women with HIV who also have a history of CSA to help HIV care providers better recognize and appreciate the distinct needs of this patient population.

    This study examines the psychological factors linking childhood abuse and HIV/sexually transmitted infection outcomes among 190 single homeless women in New York City. Participants were assessed for mental health symptoms, sexually transmitted infections, and exposure to childhood sexual and physical abuse. Findings indicate that the relationship between childhood abuse and HIV/sexually transmitted infection diagnoses during adulthood is mediated by a combination of posttraumatic stress disorder and borderline personality disorder symptoms. Screening single homeless women who report childhood abuse histories for symptoms of both disorders may aid in the identification of individuals particularly vulnerable for HIV infection. Implications for clinical interventions are discussed.

    People who use drugs are at higher risk of HIV: directly through the sharing of injecting equipment, indirectly through associated risk behavior, and physiologically through the substances' impact on the immune system. Drug users, especially people who inject drugs (PWID) are a bridge to the general population. The treatment of drug addiction and provision of harm reduction interventions have impact on HIV transmission and incidence. Addiction treatment reduces the frequency of drug-related risky behaviors and enhances access and adherence to HIV treatment, resulting in fewer new infections. However, the drug policies of many African countries are punitive and hostile to harm reduction programs. These fuel criminalization of drug use and discrimination against the drug user thereby preventing individuals with drug addiction from accessing treatment programs. There is need to formulate policies aimed at protecting the rights of people with drug addiction and address the ethical aspects of treatment.

    Despite recent clinical guidelines recommending early initiation and widespread use of antiretroviral therapy (ART), many HIV-infected individuals are not receiving ART-in particular low-income, minority substance users. Few studies have examined psychological, as opposed to structural, factors related to not receiving ART in this population. Perceived capacity to tolerate physical and psychological distress, known as distress tolerance (DT), may be a particularly relevant yet understudied factor. The current study tested the relationship between self-reported physical and psychological DT and ART receipt among predominantly low-income, minority HIV-infected substance users (n=77). Psychiatric disorders, biological indicators of health status, ART use, structural barriers to health care, and self-reported physical and psychological DT were assessed. 61% of participants were receiving ART. The only factors that distinguished individuals not on ART were greater avoidance of physical discomfort, higher psychological DT, and higher CD4 count. Both DT measures remained associated with ART use after controlling for CD4 count and were associated with almost a two-fold decrease in likelihood of ART receipt. Current findings suggest higher perceived capacity to tolerate psychological distress and greater avoidance of physical discomfort are important factors associated with lower ART use among substance users and may be important intervention targets.

    The role of HIV, hepatitis C virus, and hepatitis B virus infections in the production of biological false-positive reactions for syphilis was evaluated in two large samples of intravenous drug abusers and homosexual men attending AIDS prevention centers in Spain. A significantly increased odds ratio (OR) for false-positive tests for syphilis [OR 2.23, 95% confidence intervals (CI) 1.76-2.83] was observed for HIV-seropositive intravenous drug abusers; biological false-positive reactions were also more frequent (OR 1.73, 95% CI 1.30-2.31) among intravenous drug abusers who were hepatitis B virus seropositive but not among those who were hepatitis C virus seropositive (OR 0.90; 95% CI 0.48-1.69). Among homosexuals, the association between HIV and biological false-positive reactions was restricted to subjects who were also intravenous drug abusers, indicating the crucial role of intravenous drug abuse. Only 20.5% of intravenous drug abusers with a previous biological false-positive reaction yielded a false-positive result in their subsequent visit.

    Full Text Available Over 1.2 million people in the United States are infected with the human immunodeficiency virus (HIV. Tremendous progress has been made over the past three decades on many fronts in the prevention and treatment of HIV-1 disease. However, HIV-1 infection is incurable and antiretroviral drugs continue to remain the only effective treatment option for HIV infected patients. Unfortunately, only three out of ten HIV-1 infected individuals in the US have the virus under control. Thus, majority of HIV-1 infected individuals in the US are either unaware of their infection status or not connected/retained to care or are non-adherent to antiretroviral therapy (ART. This national public health crisis, as well as the ongoing global HIV/AIDS pandemic, is further exacerbated by substance abuse, which serves as a powerful cofactor at every stage of HIV/AIDS including transmission, diagnosis, pathogenesis, and treatment. Clinical studies indicate that substance abuse may increase viral load, accelerate disease progression and worsen AIDS-related mortality even among ART adherent patients. However, confirming a direct causal link between substance abuse and HIV/AIDS in human patients remains a highly challenging endeavor. In this review we will discuss the recent and past developments in clinical and basic science research on the effects of cocaine abuse on HIV-1 pathogenesis.

    HIV-infected individuals continue to experience neurocognitive deterioration despite virologically successful treatments. The causes of neurocognitive impairment are still unclear. However, several factors have been suggested including the role of genetics. There is evidence suggesting that neurocognitive impairment is heritable and individual differences in cognition are strongly driven by genetic variations. The contribution of genetic variants affecting the metabolism and activity of dopamine may influence these individual differences. The present study explored the relationship between two candidate genes (DRD4 and DRD2) and neurocognitive performance in HIV-infected adults. A total of 267 HIV-infected adults were genotyped for polymorphisms, DRD4 48 bp-variable number tandem repeat (VNTR), DRD2 rs6277 and ANKK1 rs1800497. The Short Category (SCT), Color Trail (CTT) and Rey-Osterrieth Complex Figure Tests (ROCT) were used to measure executive function and memory. Results showed significant associations with the SNP rs6277 and impaired executive function (odds ratio = 3.3, 95% CI 1.2-2.6; p = 0.004) and cognitive flexibility (odds ratio = 1.6, 95% CI 2.0-5.7; p = 0.001). The results were further stratified by race and sex and significant results were seen in males (odds ratio = 3.5, 95% CI 1.5-5.5; p = 0.008) and in African Americans (odds ratio = 3.1, 95% CI 2.3-3.5; p = 0.01). Also, DRD4 VNTR 7-allele was significantly associated with executive dysfunction. The study shows that genetically determined differences in the SNP rs6277 DRD2 gene and DRD4 48 bp VNTR may be risk factors for deficits in executive function and cognitive flexibility.

    Summary HIV (human immunodeficiency virus) infection may produce no clinical symptoms for 10 years on average. However, after many years of infection most people develop symptoms that indicate progression of the disease. There are no regular characteristic symptoms or early stage, and no logical sequence of AIDS indicator disorders has been observed. People who are not aware of the infection are referred to physicians of various specializations, including otolaryngologists. It is on their knowledge about HIV infections, among other factors, that early diagnosis of the disease depends. Appropriate and quick introduction of anti-retroviral drugs may let a person with HIV live decades longer. PMID:22367140

    Drug abuse and co-occurring infections are associated with significant morbidity and mortality. Asian countries are particularly vulnerable to the deleterious consequences of these risks/problems, as they have some of the highest rates of these diseases. This review describes drug abuse, HIV, and hepatitis C (HCV) in Asian countries. The most commonly used illicit drugs include opioids, amphetamine-type stimulants (ATS), cannabis, and ketamine. Among people who inject drugs, HIV rates range from 6.3 % in China to 19 % in Malaysia, and HCV ranges from 41 % in India and Taiwan to 74 % in Vietnam. In the face of the HIV epidemics, drug policies in these countries are slowly changing from the traditional punitive approach (e.g., incarcerating drug users or requiring registration as a drug user) to embrace public health approaches, including, for example, community-based treatment options as well as harm reduction approaches to reduce needle sharing and thus HIV transmission. HIV and HCV molecular epidemiology indicates limited geographic diffusion. While the HIV prevalence is declining in all five countries, use of new drugs (e.g., ATS, ketamine) continues to increase, as well as high-risk sexual behaviors associated with drug use-increasing the risk of sexual transmission of HIV, particularly among men who have sex with men. Screening, early intervention, and continued scaling up of therapeutic options (drug treatment and recovery support, ART, long-term HIV and HCV care for drug users) are critical for effective control or continued reduction of drug abuse and co-infections.

    Little attention has been given to the occurrence of dissociative symptoms during sexual behavior in adults who have experienced childhood sexual abuse (CSA). For this study, 57 adults living with HIV infection who had experienced CSA and were entering a treatment study for traumatic stress completed study assessments and clinical interviews, including a 15-item scale of dissociative experiences during sexual behavior. Predictor variables included Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision diagnoses of posttraumatic stress disorder (PTSD) and dissociative disorders, rape by an intimate partner, duration of CSA, number of perpetrators of CSA, and current sexual satisfaction. A multiple regression analysis was conducted to identify significant associations between predictors and dissociation during sex. Mean differences by clinical diagnosis were also examined. Results indicated that PTSD, dissociative disorders, rape by an intimate partner, duration of CSA, and number of perpetrators of CSA were associated with increased dissociation during sexual behavior. Dissociation during sex likely increases vulnerability to sexual revictimization and risky sexual behavior. Standard behavioral prevention interventions may be ineffective for sexual situations when dissociation occurs, and prevention efforts should be integrated with mental health care for those who have experienced CSA.

    Copper-releasing IUDs cause severe dermatitis (e.g., urticarial eruptions and eczema) in copper-sensitive women. Such exposure of subcutaneous areas is a cofactor for HIV infection. The excessive menstrual bleeding that accompanies IUD use and absorption of virions and infected cells in the semen of HIV-infected males by IUD tails facilitates HIV infection. IUD tails have the highest concentration of HIV in infected women. HIV causes cervicitis in HIV-infected women. The cross reactivity between pelvic inflammatory disease (not rare among copper-IUD users) and sexually transmitted diseases (STDs) increases the risk of HIV infection. Having multiple sex partners is a risk factor of HIV/STD infections. IUDs, diaphragms, latex condoms, and spermicides may cause an allergic reaction in men and women. Condoms made of lamb cecum are an option to men who are allergic to latex. The single greatest factor for HIV infections in Africa is chancroid. The sudden increase of syphilis in the US parallels the sudden increase in HIV transmission. Physicians need to consider the following before treating pregnant STD patients with an antibiotic: possible risk to fetus, altered kinetics and etiology of the STDs, and choice, dose, route, and duration of antibiotic treatment. Family planning services should focus on HIV-infected women, so they can avoid pregnancy. Many public health and family planning clinics offer counseling and HIV-antibody testing. Human semen has various subpopulations of leukocytes. Leukocytes that have enveloped sperm can take sperm antigens to the lymphatic system. The great individual variation in frequency of CD4+ lymphoid cells and monocytes/ macrophages is clinically important in infectivity of semen in HIV-positive men. T4+ lymphocytes are in the semen of fertile and infertile men. HIV carriers should wear condoms. Partial inactivation of HIV after 10 minutes in the condom at 37 degrees Celsius occurs, but inactivation varies by trademark.

    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.

    Most infants born to human immunodeficiency virus (HIV)-infected women escape HIV infection. Infants evade infection despite an immature immune system and, in the case of breastfeeding, prolonged repetitive exposure. If infants become infected, the course of their infection and response to treatment differs dramatically depending upon the timing (in utero, intrapartum, or during breastfeeding) and potentially the route of their infection. Perinatally acquired HIV infection occurs during a critical window of immune development. HIV's perturbation of this dynamic process may account for the striking age-dependent differences in HIV disease progression. HIV infection also profoundly disrupts the maternal immune system upon which infants rely for protection and immune instruction. Therefore, it is not surprising that infants who escape HIV infection still suffer adverse effects. In this review, we highlight the unique aspects of pediatric HIV transmission and pathogenesis with a focus on mechanisms by which HIV infection during immune ontogeny may allow discovery of key elements for protection and control from HIV. © 2013 John Wiley & Sons A/S.

    Those who have experienced abuse may be prone to engaging in risky sexual behavior and risky drug use. The relationship between sexual abuse and risky behavior has been well established in the literature, but the association between physical abuse and risky drug use has been equivocal. We hypothesize that the experience of PTSD symptoms following physical abuse leads to risky drug use. Therefore, we examined the associations among physical abuse history, PTSD symptoms, and HIV-related drug ri...

  9. HIV antibodies for treatment of HIV infection

    2016-01-01

    Summary The bar is high to improve on current combination antiretroviral therapy (ART), now highly effective, safe, and simple. However antibodies that bind the HIV envelope are able to uniquely target the virus as it seeks to enter new target cells, or as it is expressed from previously infected cells. Further, the use of antibodies against HIV as a therapeutic may offer advantages. Antibodies can have long half-lives, and are being considered as partners for long-acting antiretrovirals for use in therapy or prevention of HIV infection. Early studies in animal models and in clinical trials suggest that such antibodies can have antiviral activity but, as with small molecule antiretrovirals, the issues of viral escape and resistance will have to be addressed. Most promising, however, are the unique properties of anti-HIV antibodies: the potential ability to opsonize viral particles, to direct antibody-dependent cellular cytotoxicity (ADCC) against actively infected cells, and ultimately the ability to direct the clearance of HIV-infected cells by effector cells of the immune system. These distinctive activities suggest that HIV antibodies and their derivatives may play an important role in the next frontier of HIV therapeutics, the effort to develop treatments that could lead to an HIV cure.

    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

    Major depression is highly prevalent among HIV-positive patients (HIVpp). The prevalence of depression ranges between 18% and 81%, depending on the population studied and the methodology of the study. The etiology of depression in HIVpp is likely determined by: (i) biological factors (alterations in the white matter structure, hypothalamic-pituitary-thyroid dysfunction, Tat-protein-induced depressive behavior); (ii) psychosocial factors (HIV stigma, occupational disability, body image changes, isolation and debilitation); (iii) history or comorbidity of psychiatric illness; and (iv) the perinatal period in HIVpp women. Symptomatology of depression differs between HIVpp and HIV-negative patients (HIVnp). Depression may also alter the function of lymphocytes in HIVpp and decrease natural killer cell activity, contributing to the increased mortality in these patients. Selective serotonin re-uptake inhibitors are considered the first-line treatment. Treatment of depression can improve quality of life and lead to a better prognosis of HIV infection. © 2013 The Authors.

    As persons living with HIV infection (PLWH) live longer, primary health care and comorbidity issues have come to the forefront. The diagnosis and treatment of hypertension can affect a number of other comorbid conditions, including metabolic syndrome, lipid abnormalities, cardiovascular disease, and diabetes. Literature specific to hypertension and HIV is limited and most often presented in theory-based, rather than empirically based, articles, with hypertension-specific information presented in small sections of articles on cardiovascular disease. A systematic literature review was conducted to evaluate current research evidence to determine prevalence of hypertension in PLWH and its association with antiretroviral therapy (ART) and HIV-related and traditional risk factors. Evidence surrounding the cause and effect of HIV and ART on hypertension is conflicting and inconclusive; however, the importance of hypertension diagnosis and treatment is clear. Evidence supports use of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of Hypertension Guidelines when treating PLWH.

    Leite, Luisa Helena Maia; Cohen, Ariel; Boccara, Franck

    People living with human immunodeficiency virus (HIV) infection and receiving antiretroviral therapy now have the same life expectancy as the general population. However, they have a higher risk of atherosclerotic cardiovascular events because of a complex and polyfactorial vasculopathy, combining the effects of antiretroviral therapy, the HIV virus itself, immune activation, chronic inflammation and metabolic disturbances. Whether people living with HIV infection experience increased vascular aging compared with the general population remains controversial. To summarize current knowledge of the association between HIV infection and aortic stiffness as a marker of vascular aging. This review included 18 clinical studies in adult populations, published between 2009 and 2016, and identified on PubMed/MEDLINE or other databases. Search terms were aortic stiffness, arterial stiffness, vascular aging, pulse wave velocity and HIV. All 18 studies were observational, and compared groups infected (HIV+) and not infected (HIV-) with HIV. Ten studies (55%) reported no significant differences in aortic stiffness between HIV+ groups and age-matched HIV- control groups. The main reported determinants of aortic stiffness were age, blood pressure, smoking, metabolic syndrome and HIV-related variables, including CD4/CD8 ratio, current T-CD4 count < 200/mm 3 and nadir T-CD4+ count < 200/mm 3 . We found discordant results regarding whether HIV+ patients had increased aortic stiffness compared with HIV- controls. However, HIV-related conditions were associated with vascular health. This association has been confirmed in recent prospective studies. There is emerging evidence that HIV itself and immune activity affect vascular health and the large arteries.

    2011-01-01

    US immigrants of Caribbean origin are overrepresented in the HIV/AIDS prevalence statistics. Bidirectional travel between the United States and the Caribbean region by providing opportunities for sexual mixing may contribute to these high HIV rates. Caribbean immigrants face further risk because of limited health care access, social isolation, and stigma. Additionally, although substance abuse may not represent a major health issue in their countries of origin, Caribbean immigrants are composed disproportionately of adolescents who are at greatest risk of substance abuse. There is little information on the health care characteristics of these migrants, especially regarding HIV care. This article describes how the social and economic circumstances that surround the lives of people from the Caribbean and the challenges of the acculturation process have placed these individuals at risk of substance abuse and HIV infection. The article draws on findings from the literature and analysis of data from several sources.

    1994-09-01

    From May 1989 through April 1990, 1,001 adult homosexual and bisexual men attending urban sexually transmitted disease clinics were interviewed regarding abusive sexual contacts during childhood and adolescence. Sexual abuse was found to be significantly associated with mental health counseling and hospitalization, psychoactive substance use, depression, suicidal thought or actions, social support, sexual identity development, HIV risk behavior including unprotected and intercourse and injecting drug use, and risk of sexually transmitted diseases including HIV infection. Data suggest that sexual abuse may have a wide-ranging influence on the quality of life and health risk behavior of homosexual men. Increased awareness as to the potential outcomes of male sexual abuse is critically important to the design and implementation of medical and psychological services for sexually abused men.

    Full Text Available Alzheimer's disease (AD is characterized by progressive dysfunction of memory and higher cognitive functions with abnormal accumulation of extracellular amyloid plaques and intracellular neurofibrillary tangles throughout cortical and limbic brain regions. Withania somnifera (WS also known as 'ashwagandha' (ASH is used widely in Ayurvedic medicine as a nerve tonic and memory enhancer. However, there is paucity of data on potential neuroprotective effects of ASH against β-Amyloid (1-42 (Aβ induced neuropathogenesis. In the present study, we have tested the neuroprotective effects of Methanol: Chloroform (3:1 extract of ASH and its constituent Withanolide A (WA against Aβ induced toxicity, HIV-1(Ba-L (clade B infection and the effects of drugs of abuse using a human neuronal SK-N-MC cell line. Aβ when tested individually, induced cytotoxic effects in SK-N-MC cells as shown by increased trypan blue stained cells. However, when ASH was added to Aβ treated cells the toxic effects were neutralized. This observation was supported by cellular localization of Aβ, MTT formazan exocytosis, and the levels of acetylcholinesterase activity, confirming the chemopreventive or protective effects of ASH against Aβ induced toxicity. Further, the levels of MAP2 were significantly increased in cells infected with HIV-1(Ba-L (clade B as well as in cells treated with Cocaine (COC and Methamphetamine (METH compared with control cells. In ASH treated cells the MAP2 levels were significantly less compared to controls. Similar results were observed in combination experiments. Also, WA, a purified constituent of ASH, showed same pattern using MTT assay as a parameter. These results suggests that neuroprotective properties of ASH observed in the present study may provide some explanation for the ethnopharmacological uses of ASH in traditional medicine for cognitive and other HIV associated neurodegenerative disorders and further ASH could be a potential novel drug to

However, there is paucity of data on potential neuroprotective effects of ASH against β-Amyloid (1-42) (Aβ) induced neuropathogenesis. In the present study, we have tested the neuroprotective effects of Methanol: Chloroform (3:1) extract of ASH and its constituent Withanolide A (WA) against Aβ induced toxicity, HIV-1(Ba-L) (clade B) infection and the effects of drugs of abuse using a human neuronal SK-N-MC cell line. Aβ when tested individually, induced cytotoxic effects in SK-N-MC cells as shown by increased trypan blue stained cells. However, when ASH was added to Aβ treated cells the toxic effects were neutralized. This observation was supported by cellular localization of Aβ, MTT formazan exocytosis, and the levels of acetylcholinesterase activity, confirming the chemopreventive or protective effects of ASH against Aβ induced toxicity. Further, the levels of MAP2 were significantly increased in cells infected with HIV-1(Ba-L) (clade B) as well as in cells treated with Cocaine (COC) and Methamphetamine (METH) compared with control cells. In ASH treated cells the MAP2 levels were significantly less compared to controls. Similar results were observed in combination experiments. Also, WA, a purified constituent of ASH, showed same pattern using MTT assay as a parameter. These results suggests that neuroprotective properties of ASH observed in the present study may provide some explanation for the ethnopharmacological uses of ASH in traditional medicine for cognitive and other HIV associated neurodegenerative disorders and further ASH could be a potential novel drug to reduce

    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 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

    Summary Despite significant reductions in morbidity and mortality secondary to availability of effective combination antiretroviral therapy (cART), human immunodeficiency virus (HIV) infection still accounts for 1.5 million deaths annually. The majority of deaths occur in sub-Saharan Africa where rates of opportunistic co-infections are disproportionately high. In this review, we discuss the immunopathogenesis of five common infections that cause significant morbidity in HIV-infected patients globally. These include co-infection with Mycobacterium tuberculosis, Cryptococcus neoformans, hepatitis B virus (HBV), hepatitis C virus (HCV), and Plasmodium falciparum. Specifically, we review the natural history of each co-infection in the setting of HIV, the specific immune defects induced by HIV, the effects of cART on the immune response to the co-infection, the pathogenesis of immune restoration disease (IRD) associated with each infection, and advances in the areas of prevention of each co-infection via vaccination. Finally, we discuss the opportunities and gaps for future research. PMID:23772618

    Thrombocytopenia has been extensively reported in association with HIV infection. Twenty-four children (6%) from a cohort of 400 children with platelet counts >500,000/mm(3) were reviewed. All had symptomatic disease and 10 (42%) patients died. In 4 children the platelet count exceeded 700,000/mm(3) and in 1 patient the platelet count was 1.5 million/mm(3). There were no thrombotic complications, and no specific therapy was required for the thrombocytosis. Thus HIV-1 infection, a chronic viral infection, is another etiologic agent for thrombocytosis and is associated with severe disease.

    Child sexual abuse (CSA) has been shown to enhance risk for HIV infection and other adverse outcomes. However, most studies examine the effects of a single incident of CSA rather than the full burden of abuse over the life span in predicting these adverse outcomes. A multi-dimensional approach was used in this study to examine the severity of abuse as a predictor of post-traumatic stress, depression, sexual symptoms, and risky sexual behaviors in a multi-ethnic sample of 147 HIV-positive women. Multivariate models indicated that experiencing both intrafamilial and extrafamilial CSA, adult sexual abuse (ASA) and Latina ethnicity predicted PTSD symptoms. ASA also predicted sexual trauma symptoms. Also, CSA and adult re-victimization contributed independently to risk for PTSD and sexual trauma symptoms, but not for risky sexual behaviors. The results support the need for interventions for HIV-positive women that address the full burden of abuse experienced and its sequelae.

    Substance abuse is a common problem among HIV-infected individuals. Importantly, addictions as well as moderate use of alcohol, smoking, or other illicit drugs have been identified as major reasons for non-adherence to antiretroviral therapy (ART) among HIV patients. The literature also suggests a decrease in the response to ART among HIV patients who use these substances, leading to failure to achieve optimal virological response and increased disease progression. This review discusses the challenges with adherence to ART as well as observed drug interactions and known toxicities with major drugs of abuse, such as alcohol, smoking, methamphetamine, cocaine, marijuana, and opioids. The lack of adherence and drug interactions potentially lead to decreased efficacy of ART drugs and increased ART, and drugs of abuse-mediated toxicity. As CYP is the common pathway in metabolizing both ART and drugs of abuse, we discuss the possible involvement of CYP pathways in such drug interactions. We acknowledge that further studies focusing on common metabolic pathways involving CYP and advance research in this area would help to potentially develop novel/alternate interventions and drug dose/regimen adjustments to improve medication outcomes in HIV patients who consume drugs of abuse.

    As individuals with HIV infection are living longer, the management of psychiatric disorders has increasingly been incorporated into comprehensive care. Individuals were recruited from an outpatient HIV clinic to assess the prevalence and related associations of current psychiatric disorders and biomarkers. Of the 201 participants who completed the interviews, the median age was 43.5 years, and the majority was male and African American. Most were receiving HIV therapy and 78% of those had achieved virologic suppression. Prevalent psychiatric diagnoses included major depressive disorder, generalized anxiety, and agoraphobia. Alcohol and cocaine/crack abuse and dependence were common substance use disorders. Current receipt of HIV therapy was less common among those diagnosed with generalized anxiety disorder. Agoraphobia was the only disorder associated with unsuppressed viral load. Psychiatric and substance use disorders are highly prevalent among an urban HIV clinic population, although we identified few associations between psychiatric diagnoses and HIV diseases status. © The Author(s) 2014.

    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.

    Epidemiologic studies suggest that cocaine abuse worsens HIV-1 disease progression. Increased viral load has been suggested to play a key role for the accelerated HIV disease among cocaine-abusing patients. The goal of this study was to investigate whether cocaine enhances proviral DNA integration as a mechanism to increase viral load. We infected CD4+ T cells that are the primary targets of HIV-1 in vivo and treated the cells with physiologically relevant concentrations of cocaine (1 µM–100 µM). Proviral DNA integration in the host genome was measured by nested qPCR. Our results illustrated that cocaine from 1 µM through 50 µM increased HIV-1 integration in CD4+ T cells in a dose-dependent manner. As integration can be modulated by several early postentry steps of HIV-1 infection, we examined the direct effects of cocaine on viral integration by in vitro integration assays by use of HIV-1 PICs. Our data illustrated that cocaine directly increases viral DNA integration. Furthermore, our MS analysis showed that cocaine is able to enter CD4+ T cells and localize to the nucleus-. In summary, our data provide strong evidence that cocaine can increase HIV-1 integration in CD4+ T cells. Therefore, we hypothesize that increased HIV-1 integration is a novel mechanism by which cocaine enhances viral load and worsens disease progression in drug-abusing HIV-1 patients. PMID:25691383

    The President's National HIV/AIDS Strategy calls for coupling HIV screening and prevention services with substance abuse treatment programs. Fewer than half of US community-based substance abuse treatment programs make HIV testing available on-site or through referral. We measured the cost-effectiveness of three HIV testing strategies evaluated in a randomized trial conducted in 12 community-based substance abuse treatment programs in 2009: off-site testing referral, on-site rapid testing with information only, on-site rapid testing with risk-reduction counseling. Data from the trial included patient demographics, prior testing history, test acceptance and receipt of results, undiagnosed HIV prevalence (0.4%) and program costs. The Cost-Effectiveness of Preventing AIDS Complications (CEPAC) computer simulation model was used to project life expectancy, lifetime costs, and quality-adjusted life years (QALYs) for HIV-infected individuals. Incremental cost-effectiveness ratios (2009 US $/QALY) were calculated after adding costs of testing HIV-uninfected individuals; costs and QALYs were discounted at 3% annually. Referral for off-site testing is less efficient (dominated) compared to offering on-site testing with information only. The cost-effectiveness ratio for on-site testing with information is $60,300/QALY in the base case, or $76,300/QALY with 0.1% undiagnosed HIV prevalence. HIV risk-reduction counseling costs $36 per person more without additional benefit. A strategy of on-site rapid HIV testing offer with information only in substance abuse treatment programs increases life expectancy at a cost-effectiveness ratio substance abuse treatment leaders should seek funding to implement on-site rapid HIV testing in substance abuse treatment programs for those not recently tested.

    2014-01-01

    HIV infected patients are at increased risk for venous and arterial thromboembolic events. Multiple markers related to inflammation (IL-6, TNFrI, C-reative protein) and coagulation (tissue factor expression, FVIII, thrombin, fibrinogen and D-dimer levels) are increased in HIV infection, and several are predictive of thrombotic risk and mortality in HIV disease. The mechanisms behind the risk for abnormal coagulation in HIV infection have not been fully elucidated, but may be related to a chronic immune activation and inflammatory state in both untreated and treated HIV infection. The contribution of traditional risk factors, including smoking and dyslipidemia, overly represented in HIV infected patients, must also be considered when assessing thrombotic risk in this setting. Currently, several interventional studies are aimed at reducing inflammation and cardiovascular risk in HIV disease and may provide insights into the determinants of clotting events in HIV infected patients.

    Individuals entering substance abuse treatment are at elevated risk for HIV infection, and clinicians must generally rely on patient self-report to gauge their involvement in risk behaviors. Strategies to improve accurate reporting of personally sensitive or stigmatizing risk behaviors are needed. This study compared computerized and face-to-face interview methods in eliciting self-disclosure of HIV risk behaviors among a high-risk sample of urban African Americans entering substance abuse treatment (N = 146). Participants completed a standardized HIV risk behavior screening as a face-to-face interview. Several days later, the same participants completed a computerized self-interview with the same measure, covering the same time frame. Disclosure rates for many sensitive risk behaviors were considerably higher on the computerized interview. Participants had significantly higher odds of disclosure on the computerized interview compared to the face-to-face interview on 2 of 6 drug risk behaviors examined (ORs between 2.75 and 3.15) and 9 of 13 sex risk behaviors examined (ORs between 1.60 and 6.45). The advantage of the computerized interview was most evident for highly stigmatized behaviors, such as unprotected sex with someone other than a spouse or main partner (OR = 3.93; p behavior assessment with African Americans entering substance abuse treatment. Computerized assessment of HIV risk behaviors may be clinically useful in substance abuse treatment and other healthcare venues serving high-risk populations.

  20. Avascular necrosis of the femoral head in HIV infected patients

    Marcos Almeida Matos

    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/AIDS is one of the leading causes of death among reproductive-age women throughout the world, and substance abuse plays a major role in HIV infection. We conducted a systematic review, in accordance with the 2015 Preferred Items for Reporting Systematic Reviews and Meta-analysis tool, to assess HIV risk-reduction intervention studies among reproductive-age women who abuse substances. We initially identified 6,506 articles during our search and, after screening titles and abstracts, examining articles in greater detail, and finally excluding those rated methodologically weak, a total of 10 studies were included in this review. Studies that incorporated behavioral skills training into the intervention and were based on theoretical model(s) were the most effective in general at decreasing sex and drug risk behaviors. Additional HIV risk-reduction intervention research with improved methodological designs is warranted to determine the most efficacious HIV risk-reduction intervention for reproductive-age women who abuse substances.

    Young women with HIV and histories of physical and/or sexual abuse in childhood may be vulnerable to difficulties with disclosure to sexual partners. Abuse in childhood is highly prevalent in HIV-positive women, and has been associated with poorer communication, low assertiveness, low self worth, and increased risk for sexual and other risk behaviors that increase the risk of secondary transmission of HIV. HIV disclosure may be an important link between abuse and sexual risk behaviors. Qualitative interviews with 40 HIV-positive young women with childhood physical and/or sexual abuse were conducted; some women had also experienced adult victimization. Results suggest that HIV-positive women with abuse histories use a host of strategies to deal with disclosure of HIV status, including delaying disclosure, assessing hypothetical responses of partners, and determining appropriate stages in a relationship to disclose. Stigma was an important theme related to disclosure. We discuss how these disclosure processes impact sexual behavior and relationships and discuss intervention opportunities based on our findings.

    Domestic violence is one of the most prevalent problems linked to HIV. Domestic violence in HIV-infected women has not been sufficiently explored, particularly in developing countries including Iran. This study aimed to explore the lived experience of domestic violence in Iranian HIV-infected women. A qualitative approach was used to conduct the study. Data were collected through semi-structured, in-depth interviews with ten HIV-infected women and were analyzed using content analysis. During the data analysis, four main themes emerged including, "regretful past", "disappointing future", "loneliness", and "no other option", which refer to the condition that the participants experienced in their lives due to challenges that mainly stem from the experience of HIV-related domestic violence. HIV infection can be a risk factor for domestic violence. Health care providers need to address domestic violence during the assessment of HIV-infected women and make appropriate referrals for abused women.

    The global HIV/AIDS pandemic has claimed the lives of an estimated 35 million people. A significant barrier for combating this global pandemic is substance use since it is associated with HIV transmission, delayed diagnosis/initiation of therapy, and poor adherence to therapy. Clinical studies also suggest a link between substance use and HIV-disease progression/AIDS-associated mortality. Methamphetamine (METH) use is one of the fastest-growing substance use problems in the world. METH use enhances high-risk sexual behaviors, therefore increases the likelihood of HIV-1 acquisition. METH use is also associated with higher viral loads, immune dysfunction, and antiretroviral resistance. Moreover, METH use has also been correlated with rapid progression to AIDS. However, direct effects of METH on HIV-1 disease progression remains poorly understood because use of METH and other illicit drugs is often associated with reduced/non adherence to ART. Nevertheless, in vitro studies demonstrate that METH increases HIV-1 replication in cell cultures and animal models. Thus, it has been proposed that METH's potentiating effects on HIV-1 replication may in part contribute to the worsening of HIV-1 pathogenesis. However, our recent data demonstrate that METH at physiologically relevant concentrations has no effect and at higher concentrations inhibits HIV-1 replication in CD4+ T cells. Thus, the goal of this review is to systematically examine the published literature to better understand the complex interaction between METH abuse and HIV-1 disease progression.

    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.

    Abstract Childhood sexual abuse is prevalent among people living with HIV, and the experience of shame is a common consequence of childhood sexual abuse and HIV infection. This study examined the role of shame in health-related quality of life among HIV-positive adults who have experienced childhood sexual abuse. Data from 247 HIV-infected adults with a history of childhood sexual abuse were analyzed. Hierarchical linear regression was conducted to assess the impact of shame regarding both sexual abuse and HIV infection, while controlling for demographic, clinical, and psychosocial factors. In bivariate analyses, shame regarding sexual abuse and HIV infection were each negatively associated with health-related quality of life and its components (physical well-being, function and global well-being, emotional and social well-being, and cognitive functioning). After controlling for demographic, clinical, and psychosocial factors, HIV-related, but not sexual abuse-related, shame remained a significant predictor of reduced health-related quality of life, explaining up to 10% of the variance in multivariable models for overall health-related quality of life, emotional, function and global, and social well-being and cognitive functioning over and above that of other variables entered into the model. Additionally, HIV symptoms, perceived stress, and perceived availability of social support were associated with health-related quality of life in multivariable models. Shame is an important and modifiable predictor of health-related quality of life in HIV-positive populations, and medical and mental health providers serving HIV-infected populations should be aware of the importance of shame and its impact on the well-being of their patients.

    Pain syndromes are common in HIV-infected patients, who also are commonly affected by opioid-use disorders. Although opioids can treat pain, prescribers must consider the consequences of iatrogenic or missed addiction diagnoses. In an anonymous online survey, we asked a national sample of HIV providers about their demographics, experience, and patients, and their practices and attitudes about chronic opioid therapy, addiction, and confidence recognizing opioid analgesic abuse. One hundred six providers reported 28% of their patients had chronic pain; 21% received opioid analgesics; 37% were HIV infected by injecting drug use; and 12% were addicted to prescription opioids. Few providers followed recommended guidelines for chronic opioid therapy in nonmalignant pain. Mean provider confidence was 6.3 on a scale of 10. Higher confidence was associated with provider sex (P opioids (P = 0.005), and prescribing buprenorphine (P = 0.009). HIV providers seldom follow recommended guidelines for opioid prescribing and have limited confidence in their ability to recognize opioid analgesic abuse. Clinical practices developed to reduce misuse and increase early detection and treatment of opioid dependence are associated with higher confidence. The implementation of guidelines to improve the quality of opioid prescribing in HIV clinics may aid in the diagnosis of addictive disorders and prevent their adverse outcomes.

    In the absence of HIV testing, how do rural Malawians assess their HIV status? In this paper, we use a unique dataset that includes respondents' HIV status as well as their subjective likelihood of HIV infection. These data show that many rural Malawians overestimate their likelihood of current HIV infection. The discrepancy between actual and perceived status raises an important question: Why are so many wrong? We begin by identifying determinants of self-assessed HIV status, and then compar...

  19. 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.

    Full Text Available Introduction: People with AIDS can have a dysfunction of the hypothalamic - pituitary-adrenal axis. With regard to HIV infection, most often mentioned is iatrogenic Cushing's syndrome or Pseudo-Cushing's Syndrome. So far there are described only two cases of Cushing disease in HIV -infected persons. Case report: A 48-year-old patient, after eleven years of HIV infection and a year since the introduction of HAART, was diagnosed with Cushing's disease based on cushingoid habitus, lack of suppression of cortisol in screening, elevated ACTH and pituitary tumor. She had transfenoidal surgery and histopathologic findings corresponded to basophilic adenoma. After the operation, short time on hydrocortisone substitution, she generally felt well with regular ART. Four years later, again easily bruising, facial redness, oily skin with acne, weight gain, uneven distribution of stomach adipose tissue, sweating, oligomenorrhea and high blood pressure. There was no rest/relapse of tumor on control pituitary MRI. Initially, elevated ACTH, valid cortisol in daily profiles, later the absence of the suppression of cortisol after 4 mg (LDST and 8 mg (HDST of dexamethasone along with maintenance of higher ACTH, indicate recurrence of clinical and laboratory relapse wherefore ketoconazole was introduced. Despite increasing doses of ketoconazole, she held slightly higher morning cortisol, ACTH and with persisting Cushing's syndrome. Conclusion: The coexistence of the two entities could lead to overlapping metabolic and phenotypic characteristics and the interaction between and/or synergism.

    Chronic traumatism of the common femoral artery due to intravenous injection in drug abusers, in association with local infections and arterial wall weakening caused by human immunodeficiency virus (HIV), can lead to the development of pseudoaneurysms (PSAs). Rupture of PSA is a dramatic event in such patients, and its correction is difficult and controversial. Most of the cases reported describe open surgical elective options, which consist in ligation, repair, or substitution of the damaged arterial segment, using when possible biological grafts. In literature, few cases describe an endovascular repair with covered stent deployment. We present 2 cases of HIV-positive intravenous injection in drug abusers who needed emergency treatment for active bleeding in ruptured PSA of the right common femoral artery. In both cases, under general anesthesia needed for lack of patient's compliance and unstable hemodynamics, a short dissection to the distal superficial femoral artery was required. Then, maintaining a manual compression on the bleeding site to stop hemorrhage, we deployed a covered stent graft in the site of the arterial breakdown through a retrograde approach. The favorable results and progressive healing of wound and local infections persuaded us not to perform any further surgical correction. The absence of recurrences and late complications, after 3 years in the first case and 1 year in the second one, lead us to consider this hybrid endovascular approach as a valuable alternative to open surgery in HIV intravenous injection in drug abuser patients, in particularly when emergency conditions occur.

    2016-01-01

    If we have any hope of achieving a cure for HIV infection, close attention to the cell types capable of getting infected with HIV is necessary. Of these cell types, astrocytes are the most ideal cell type for the formation of such a reservoir. These are long-lived cells with a very low turnover rate and are found in the brain and the gastrointestinal tract. Although astrocytes are evidently resistant to infection of cell-free HIV in vitro, these cells are efficiently infected via cell-tocell contact by which immature HIV virions bud off lymphocytes and have the ability to directly bind to CXCR4, triggering the process of fusion in the absence of CD4. In this review, we closely examine the evidence for HIV infection of astrocytes in the brain and the mechanisms for viral entry and regulation in this cell type, and discuss an approach for controlling this viral reservoir.

    HIV diagnosis, the first step in HIV care and treatment engagement, may be inhibited by substance use among female sex workers (FSW). We assessed the relationship between alcohol and cannabis use and lack of HIV infection awareness among HIV-infected FSW in Lilongwe, Malawi. From July to September, 2014, 200 FSW aged ≥18 years were enrolled using venue-based sampling to examine substance use, HIV testing history, and serostatus ascertained by HIV rapid test. We used Poisson regression with robust variance estimates to estimate the associations of alcohol and cannabis use and lack of HIV infection awareness. Of the 138 HIV-infected FSW, 20% were unaware of their HIV infection, with 70% not testing within 6 months prior. According to the Alcohol Use Disorder Identification Tests (AUDIT), 55% of FSW unaware of their HIV infection reported hazardous, harmful, or dependent alcohol consumption. We observed a dose-response relationship between alcohol use and lack of HIV infection awareness, with alcohol dependency significantly associated with lack of HIV infection awareness (adjusted prevalence ratio: 3.0, 95% CI: 1.3, 6.8). Current cannabis use was uncommon (26%) among unaware HIV-infected FSW and weakly associated with lack of HIV infection awareness adjusted prevalence ratio: 1.1, 95% CI: 0.5, 2.5). Increased levels of alcohol use is associated with lack of HIV infection awareness among HIV-infected FSW in Malawi. Frequent, consistent HIV testing integrated with alcohol reduction strategies could improve the health and infection awareness of substance-using FSW. Copyright © 2016 Elsevier B.V.

    Clinical management of HIV must account for the "triple diagnosis" of HIV, psychiatric diagnosis, and substance use disorders and requires integrated treatment services that focus beyond just mitigation of substance use and psychiatric and medical symptoms but also address other health behaviors. Because clinical management of HIV/AIDS has shifted significantly with the advent of highly active antiretroviral therapies (HAART) in the mid 1990s, a literature review focusing on literature published since 2000, and using relevant key words was conducted using a wide range of literature search databases. This literature review was complemented by studies to expand on specific treatment modalities for which there was a dearth of literature addressing HIV infected cohorts and to provide discussion of issues around substance abuse treatment as an HIV prevention tool. Existing models of substance abuse treatment including cognitive behavioral therapy and motivational interviewing have proven to be useful for enhancing adherence and reducing substance use in outpatient populations, while methadone maintenance and directly observed treatment have been useful with specific subgroups of users. Contextualization of services heightens the likelihood of successful outcomes and relapse prevention.

    Perry, Nicky

    Approximately 96,000 people are living with HIV in the UK, a quarter of whom are unaware they are infected. While in some parts of the world the number of people newly infected with HIV has fallen, in the UK in 2011 there was a rise in the number of men who have sex with men being diagnosed. HIV prevention strategies are a public health priority, while ongoing research into HIV testing in all clinical settings remains a priority. This article explores preventive measures that can be used to reduce the spread of HIV and offers advice on how nurses can contribute to these.

    Considerable insight has been gained into the comorbid, interactive effects of HIV and drug abuse in the brain using experimental models. This review, which considers opiates, methamphetamine, and cocaine, emphasizes the importance of host genetics and glial plasticity in driving the pathogenic neuron remodeling underlying neuro-acquired immunodeficiency syndrome and drug abuse comorbidity. Clinical findings are less concordant than experimental work, and the response of individuals to HIV and to drug abuse can vary tremendously. Host-genetic variability is important in determining viral tropism, neuropathogenesis, drug responses, and addictive behavior. However, genetic differences alone cannot account for individual variability in the brain "connectome." Environment and experience are critical determinants in the evolution of synaptic circuitry throughout life. Neurons and glia both exercise control over determinants of synaptic plasticity that are disrupted by HIV and drug abuse. Perivascular macrophages, microglia, and to a lesser extent astroglia can harbor the infection. Uninfected bystanders, especially astroglia, propagate and amplify inflammatory signals. Drug abuse by itself derails neuronal and glial function, and the outcome of chronic exposure is maladaptive plasticity. The negative consequences of coexposure to HIV and drug abuse are determined by numerous factors including genetics, sex, age, and multidrug exposure. Glia and some neurons are generated throughout life, and their progenitors appear to be targets of HIV and opiates/psychostimulants. The chronic nature of HIV and drug abuse appears to result in sustained alterations in the maturation and fate of neural progenitors, which may affect the balance of glial populations within multiple brain regions. © 2014 Elsevier Inc.

    Childhood sexual abuse (CSA), adult sexual abuse (ASA) and intimate partner violence (IVP) are documented risk factors for HIV infection and are often implicated in the presentation of mental health disorders in both males and females, including those who are vulnerable to HIV-infection (African-Americans; trauma survivors). As such, these issues may contribute to health-related challenges among couples, particularly if the individuals are impacted by histories of trauma and HIV. Presented here is a case study of one couple with self-reported histories of CSA and clinically significant symptoms of posttraumatic stress disorder (PTSD) and depression. This couple was selected from a larger National Institute of Mental Health (NIMH)-funded study of 535 African-American HIV-serodiscordant heterosexual couples (see El Bassel, 2010). The study couple completed 8 sessions of an HIV sexual risk reduction intervention program to increase condom use. Although the couple reported an initial increase in condom use at the immediate post intervention assessment, condom use decreased to baseline assessment levels at the 12-month post intervention assessment. The decrease in HIV-transmission protective behaviors over time (i.e., condom use), in part, may be attributable to the clinically significant psychological distress symptoms of PTSD and depression that were maintained from baseline, throughout the trial, and at follow-up assessments. We propose that the success of sexual risk reduction interventions may be attenuated and compromised over time by the presence of sexual trauma histories and the residual mental health issues. We discuss clinical implications for health care professionals in their work with couples, especially those from racially diverse groups.

    Full Text Available Frailty is associated with morbidity and premature mortality among elderly HIV-uninfected adults, but the determinants and consequences of frailty in HIV-infected populations remain unclear. We evaluated the correlates of frailty, and the impact of frailty on mortality in a cohort of aging injection drug users (IDUs.Frailty was assessed using standard criteria among HIV-infected and uninfected IDUs in 6-month intervals from 2005 to 2008. Generalized linear mixed-model analyses assessed correlates of frailty. Cox proportional hazards models estimated risk for all-cause mortality.Of 1230 participants at baseline, the median age was 48 years and 29% were HIV-infected; the frailty prevalence was 12.3%. In multivariable analysis of 3,365 frailty measures, HIV-infected IDUs had an increased likelihood of frailty (OR, 1.66; 95% CI, 1.24-2.21 compared to HIV-uninfected IDUs; the association was strongest (OR, 2.37; 95% CI, 1.62-3.48 among HIV-infected IDUs with advanced HIV disease (CD4<350 cells/mm3 and detectable HIV RNA. No significant association was seen with less advanced disease. Sociodemographic factors, comorbidity, depressive symptoms, and prescription drug abuse were also independently associated with frailty. Mortality risk was increased with frailty alone (HR 2.63, 95% CI, 1.23-5.66, HIV infection alone (HR 3.29, 95% CI, 1.85-5.88, and being both HIV-infected and frail (HR, 7.06; 95%CI 3.49-14.3.Frailty was strongly associated with advanced HIV disease, but IDUs with well-controlled HIV had a similar prevalence to HIV-uninfected IDUs.

    2009-04-01

    The prevalence of childhood sexual and physical abuse among persons with severe mental illness (SMI) is disproportionately high. Adults with SMI also engage in high rates of HIV risk behaviors. This study examined the association between childhood abuse and adult victimization, substance abuse, and lifetime HIV sexual risk in a sample of 152 adults with SMI receiving community mental health services. Structured interviews assessed psychiatric, psychosocial, and behavioral risk factors. Seventy percent reported childhood physical and/or sexual abuse, and 32% reported both types of abuse. Participants with childhood abuse were more likely to report adult victimization and greater HIV risk. A structural equation model found that childhood abuse was directly and indirectly associated with HIV risk through drug abuse and adult vicitimization. Integrated treatment approaches that address interpersonal violence and substance abuse may be necessary for HIV risk reduction in this population.

    Childhood sexual abuse (CSA) has been reported to be disproportionately higher among men who have sex with men (MSM) than among heterosexual men; it has also been found to be significantly positively associated with HIV status and HIV risk factors, including unprotected anal intercourse. The purpose of this study was to assess the correlates of CSA in a sample of community-recruited MSM, investigate race as a potential effect modifier, and describe the independent association between CSA and HIV infection in Washington, DC. A total of 500 MSM were recruited by venue-based sampling in 2008 as part of the National HIV Behavioral Surveillance. More than one-half of MSM identified as White, while one-third identified as Black. CSA was reported by 17.5 % of the 451 MSM, with the first instance of abuse occurring at a median age of 8.3 (interquartile range = 5.0, 11.0). In multivariable analysis, HIV-positive men were significantly more likely to report a history of CSA compared to HIV-negative men after adjusting for intimate partner violence in the last 12 months, having been arrested in the last 12 months, and depressive symptoms. HIV-positive MSM had more than four times the odds of reporting CSA after controlling for other correlates (aOR = 4.19; 95 % CI 2.26, 7.75). Despite hypothesizing that race modified the effect of CSA on HIV infection we found this was not the case in this sample. More research is needed to investigate the potential pathway between a history of CSA and HIV infection, and how this contributes to driving the HIV epidemic among MSM in Washington, DC.

  3. Cyclophilin B enhances HIV-1 infection

    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. - Highlights: • CypB has been identified in several proteomic studies of HIV-1 infection. • CypB expression is upregulated in activated and infected T-cells. • Over-expression of CypB enhances HIV nuclear import and infection. • The N-terminus of CypB is necessary for these effects.

    This study was conducted to determine the current molecular prevalence of human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), hepatitis D virus (HDV), and human T lymphotropic virus-1/2 (HTLV-1/2) circulating among drug abuser inmates incarcerated in prisons located in Central Java, Indonesia. Socio-epidemiological data and blood specimens were collected from 375 drug abuser inmates in four prisons. The blood samples were analyzed with serological and molecular testing for HIV, HBV, HCV, HDV, and HTLV-1/2. The seroprevalence of HIV, HBsAg, HCV, HDV, and HTLV-1/2 in drug abuser inmates was 4.8% (18/375), 3.2% (12/375), 34.1% (128/375), 0% (0/375), and 3.7% (14/375), respectively. No co-infections of HIV and HBV were found. Co-infections of HIV/HCV, HIV/HTLV-1/2, HBV/HCV, HBV/HTLV-1/2, and HCV/HTLV-1/2 were prevalent at rates of 4% (15/375), 1.3% (5/375), 1.1% (4/375), 0.3% (1/375), and 2.1% (8/375), respectively. The HIV/HCV co-infection rate was significantly higher in injection drug users (IDUs) compared to non-IDUs. Triple co-infection of HIV/HCV/HTLV-1/2 was found only in three IDUs (0.8%). HIV CRF01_AE was found to be circulating in the inmates. HBV genotype B3 predominated, followed by C1. Subtypes adw and adr were found. HCV genotype 1a predominated among HCV-infected inmates, followed by 1c, 3k, 3a, 4a, and 1b. All HTLV-1 isolates shared 100% homology with HTLV-1 isolated in Japan, while all of the HTLV-2 isolates were subtype 2a. Drug abuser inmates in prisons may offer a unique community to bridge prevention and control of human blood-borne virus infection to the general community.

    Patients with severe immunosuppression as a consequence of infection by human immunodeficiency virus (HIV) are at risk for a number of severe periodontal diseases. HIV-associated gingivitis and HIV-associated periodontitis (HIV-P) are seen exclusively in HIV-infected persons. In some cases HIV-P may extend into adjacent soft tissue and bone, resulting in necrotizing stomatitis of periodontal origin. In addition, acute necrotizing ulcerative gingivitis has also been reported to have an increased prevalence in HIV-infected patients. The clinical and microbiologic features of HIV-associated gingivitis and HIV-P suggest that these diseases are early and later stages of the same lesion, that results in severe gingival erythema, extensive soft tissue necrosis, and destruction of alveolar bone. Although acute necrotizing gingivitis and the initial stages of HIV-P share a number of clinical signs current evidence indicates that they are distinct pathologic processes. Treatment of these lesions requires debridement, local antimicrobial therapy, immediate follow-up care, and long-term maintenance. In addition, patients with systemic involvement or extensive and rapidly progressing lesions may require systemic antibiotics appropriate to the organisms that dominate the lesion.

    Drug abuse is a major comorbidity of HIV infection and cognitive disorders are often more severe in the drug abusing HIV infected population. CD14+CD16+ monocytes, a mature subpopulation of peripheral blood monocytes, are key mediators of HIV neuropathogenesis. Infected CD14+CD16+ monocyte transmigration across the blood brain barrier mediates HIV entry into the brain and establishes a viral reservoir within the CNS. Despite successful antiretroviral therapy, continued influx of CD14+CD16+ monocytes, both infected and uninfected, contributes to chronic neuroinflammation and the development of HIV associated neurocognitive disorders (HAND). Drug abuse increases extracellular dopamine in the CNS. Once in the brain, CD14+CD16+ monocytes can be exposed to extracellular dopamine due to drug abuse. The direct effects of dopamine on CD14+CD16+ monocytes and their contribution to HIV neuropathogenesis are not known. In this study, we showed that CD14+CD16+ monocytes express mRNA for all five dopamine receptors by qRT-PCR and D1R, D5R and D4R surface protein by flow cytometry. Dopamine and the D1-like dopamine receptor agonist, SKF38393, increased CD14+CD16+ monocyte migration that was characterized as chemokinesis. To determine whether dopamine affected cell motility and adhesion, live cell imaging was used to monitor the accumulation of CD14+CD16+ monocytes on the surface of a tissue culture dish. Dopamine increased the number and the rate at which CD14+CD16+ monocytes in suspension settled to the dish surface. In a spreading assay, dopamine increased the area of CD14+CD16+ monocytes during the early stages of cell adhesion. In addition, adhesion assays showed that the overall total number of adherent CD14+CD16+ monocytes increased in the presence of dopamine. These data suggest that elevated extracellular dopamine in the CNS of HIV infected drug abusers contributes to HIV neuropathogenesis by increasing the accumulation of CD14+CD16+ monocytes in dopamine rich brain

    Introduction: HIV-related stigma and discrimination and disrespect and abuse during childbirth are barriers to use of essential maternal and HIV health services. Greater understanding of the relationship between HIV status and disrespect and abuse during childbirth is required to design interventions to promote women's rights and to increase uptake of and retention in health services; however, few comparative studies of women living with HIV (WLWH) and HIV-negative women exist. Methods: Mixed methods included interviews with postpartum women (n = 2000), direct observation during childbirth (n = 208), structured questionnaires (n = 50), and in-depth interviews (n = 18) with health care providers. Bivariate and multivariate regressions analyzed associations between HIV status and disrespect and abuse, whereas questionnaires and in-depth interviews provided insight into how provider attitudes and workplace culture influence practice. Results: Of the WLWH and HIV-negative women, 12.2% and 15.0% reported experiencing disrespect and abuse during childbirth (P = 0.37), respectively. In adjusted analyses, no significant differences between WLWH and HIV-negative women's experiences of different types of disrespect and abuse were identified, with the exception of WLWH having greater odds of reporting non-consented care (P = 0.03). None of the WLWH reported violations of HIV confidentiality or attributed disrespect and abuse to their HIV status. Provider interviews indicated that training and supervision focused on prevention of vertical HIV transmission had contributed to changing the institutional culture and reducing HIV-related violations. Conclusions: In general, WLWH were not more likely to report disrespect and abuse during childbirth than HIV-negative women. However, the high overall prevalence of disrespect and abuse measured indicates a serious problem. Similar institutional priority as has been given to training and supervision to reduce HIV-related discrimination

    To review recent studies reporting epidemiological and public health aspects of primary and recently acquired HIV infection, with a particular emphasis on patterns of occurrence, relationship to onward transmission, diagnostic strategies and risk factors. Diagnosis of primary HIV infection remains a relatively infrequent occurrence. Clinical and demographic characteristics may be helpful indicators to guide the decision to offer testing. The high levels of viraemia associated with primary HIV infection represent a particular risk of onward transmission, as recently demonstrated through studies using genotyping methods to link newly acquired cases. Diagnostic strategies involving nucleic acid detection have been increasingly used to identify cases prior to the development of antibodies. Serological tests for early infection are valid for epidemiological purposes but are not generally viewed reliable enough for individual diagnosis. Prospective studies continue to be a useful means of identifying factors associated with the risk of newly acquired HIV infection, and can guide the implementation and evaluation of prevention strategies. The occurrence of primary HIV infection is an event of public health importance. Understanding of the extent of primary HIV infection and its risk factors in populations can guide the development and evaluation of preventive interventions.

    . 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.

    The objective is to clarify the role of immunodeficiency and pneumonia in elevated lung cancer risk among HIV-infected individuals. Cohort study of HIV-infected and HIV-uninfected adults in a large integrated healthcare system in California during 1996-2011. We used Poisson models to obtain rate ratios for lung cancer associated with HIV infection, overall and stratified by recent CD4 cells/μl (HIV-uninfected as reference group), with χ tests for trends across CD4 strata. Fully adjusted models included demographics, cancer risk factors (smoking, drug/alcohol abuse, overweight/obesity), and prior pneumonia. Among 24 768 HIV-infected and 257 600 HIV-uninfected individuals, the lung cancer rate per 100 000 person-years was 66 (n = 80 events) for HIV-infected and 33 (n = 506 events) for HIV-uninfected individuals [rate ratio 2.0, 95% confidence interval (CI): 1.7-2.2]. Overall, HIV-infected individuals were at increased risk of lung cancer after adjustment for demographics and cancer risk factors (rate ratio 1.4, 95% CI: 1.1-1.7), but not after additional adjustment for pneumonia (rate ratio 1.2, 95% CI: 0.9-1.6). Lower CD4 cell counts were associated with higher risk of lung cancer in unadjusted and demographics-adjusted models (P HIV-uninfected individuals, HIV-infected individuals with CD4 less than 200 cells/μl were not at increased risk of lung cancer in fully adjusted models. The increased lung cancer risk among HIV patients is attributable to differences in demographics, risk factors such as smoking, and history of pneumonia. Immunodeficiency does not appear to have an independent effect on lung cancer risk.

    Rapid and precise quantification of the infectivity of HIV is important for molecular virologic studies, as well as for measuring the activities of antiviral drugs and neutralizing antibodies. An indicator cell line, a CCD camera, and image-analysis software are used to quantify HIV infectivity. The cells of the P4R5 line, which express the receptors for HIV infection as well as β-galactosidase under the control of the HIV-1 long terminal repeat, are infected with HIV and then incubated 2 days later with X-gal to stain the infected cells blue. Digital images of monolayers of the infected cells are captured using a high resolution CCD video camera and a macro video zoom lens. A software program is developed to process the images and to count the blue-stained foci of infection. The described method allows for the rapid quantification of the infected cells over a wide range of viral inocula with reproducibility, accuracy and at relatively low cost.

    Within the last 30 years, the human immunodeficiency virus (HIV) infection has changed its status from inevitably fatal to chronic disorder with limited impact on life span. However, this breakthrough was mainly the effect of introduction of the aggressive antiviral treatment, which has led to the clinically significant increase in CD4+ cell count, resulting in fewer cases of the acquired immunodeficiency syndrome (AIDS) and improved management of opportunistic infections occurring in the course of the disease. The occurrence of a particular autoimmune disease depends on degree of immunosuppression of the HIV-positive patient. In 2002, four stages of autoimmunity were proposed in patients infected by HIV, based on the absolute CD4+ cell count, feature of AIDS as well as on the presence of autoimmune diseases. Spectrum of autoimmune diseases associated with HIV infection seems to be unexpectedly wide, involving several organs, such as lungs (sarcoidosis), thyroid gland (Graves' disease), liver (autoimmune hepatitis), connective tissue (systemic lupus erythematosus, rheumatoid arthritis, polyarteritis nodosa and other types of vasculitis, antiphospholipid syndrome) or hematopoietic system (autoimmune cytopenias). This paper contains the state of art on possible coincidences between HIV infection and a differential types of autoimmune diseases, including the potential mechanisms of this phenomenon. As the clinical manifestations of autoimmunization often mimic those inscribed in the course of HIV infection, health care providers should be aware of this rare but potentially deadly association and actively seek for its symptoms in their patients.

    Full Text Available Human Immune-deficiency Virus (HIV was first discovered in 1981 in the United States of America and the day of December 1, was announced as ?World AIDS Day? by WHO (World Health Organization. In Turkey, the first announcement of the people living with HIV was made in 1985. HIV/AIDS has killed more than 20 millions people and more than 16,000 people become newly infected each day since the first cases were diagnosed in 1981. It is estimated that 39.4 million people would have been infected with HIV at the end of 2004, with 4.9 million new cases that year. Sub-Saharan Africa is the worst-hit region, with 70 percent of all people living with HIV. In Africa alone, 10,000 people become infected each day. This year?s main theme is ?Women, Girls, HIV and AIDS,? which reflects a focus on how the effects of HIV/AIDS have significantly increased among women.

    The induction of neutralizing antibodies directed against the human immunodeficiency virus (HIV) has received considerable attention in recent years, in part driven by renewed interest and opportunities for antibody-based strategies for prevention such as passive transfer of antibodies and the development of preventive vaccines, as well as immune-based therapeutic interventions. Advances in the ability to screen, isolate, and characterize HIV-specific antibodies have led to the identification of a new generation of potent broadly neutralizing antibodies (bNAbs). The majority of these antibodies have been isolated from B cells of chronically HIV-infected individuals with detectable viremia. In this review, we provide insight into the phenotypic and functional attributes of human B cells, with a focus on HIV-specific memory B cells and plasmablasts/cells that are responsible for sustaining humoral immune responses against HIV. We discuss the abnormalities in B cells that occur in HIV infection both in the peripheral blood and lymphoid tissues, especially in the setting of persisting viremia.

    2003-10-01

    The worldwide infection rate for HIV-1 is estimated to be 14,000 per day, but only now, more than 20 years into the epidemic, are the immediate events between exposure to infectious virus and the establishment of infection becoming clear. Defining the mechanisms of HIV-1 transmission, the target cells involved and how the virus attaches to and fuses with these cells, could reveal ways to block the sexual spread of the virus. In this review, we will discuss how our increasing knowledge of the ways in which HIV-1 is transmitted is shaping the development of new, more sophisticated intervention strategies based on the application of vaginal or rectal microbicides.

    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.

    The prevalence of post-traumatic stress disorder (PTSD) is higher among HIV-infected (HIV+) women compared with HIV-uninfected (HIV-) women, and deficits in episodic memory are a common feature of both PTSD and HIV infection. We investigated the association between a probable PTSD diagnosis using the PTSD Checklist-Civilian (PCL-C) version and verbal learning and memory using the Hopkins Verbal Learning Test in 1004 HIV+ and 496 at-risk HIV- women. HIV infection was not associated with a probable PTSD diagnosis (17% HIV+, 16% HIV-; p = 0.49) but was associated with lower verbal learning (p learning (p < 0.01) and memory (p < 0.01) and psychomotor speed (p < 0.001). The particular pattern of cognitive correlates of probable PTSD varied depending on exposure to sexual abuse and/or violence, with exposure to either being associated with a greater number of cognitive domains and a worse cognitive profile. A statistical interaction between HIV serostatus and PTSD was observed on the fine motor skills domain (p = 0.03). Among women with probable PTSD, HIV- women performed worse than HIV+ women on fine motor skills (p = 0.01), but among women without probable PTSD, there was no significant difference in performance between the groups (p = 0.59). These findings underscore the importance of considering mental health factors as correlates to cognitive deficits in women with HIV.

    We aimed to describe the current and desired involvement of family physicians (FPs) in the treatment of HIV patients (screening practices, potential training and patient follow-up) to reduce the duration and frequency of their hospital treatment. We conducted a descriptive cross-sectional survey between 2011 and 2012 with the support of COREVIH (Regional Coordinating Committee on HIV). We sent a self-assessment questionnaire to all FPs of the Pays de la Loire region to enquire about their HIV screening practices and expectations for the management of HIV patients. A total of 871 FPs completed the questionnaire (response rate: 30.4%). A total of 54.2% said to provide care to HIV patients; the mean number of HIV patients per FP was estimated at 1.4. With regard to HIV screening, 12.2% systematically suggest an HIV serology to their patients and 72.7% always suggest it to pregnant women. About 45.4% of responding FPs said to be willing to manage HIV patients (clinical and biological monitoring, compliance checks and prescription renewal). FPs mainly reported the lack of training and the low number of HIV patients as a barrier to their further involvement in the management of HIV patients. The responding FPs provide care to very few HIV patients. They are, however, willing to be more involved in the routine care of these patients. Medical training provided by COREVIH would help improve HIV screening. The management of HIV patients could thus be handed over to willing FPs. Copyright © 2015. Published by Elsevier SAS.

    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.

    Infections due to pneumococci are frequent in patients infected with the human immunodeficiency virus (HIV), but joint infections are rare. We observed two cases of septic arthritis due to pneumococci in two non-haemophilic HIV seropositive patients. In the first case, a 31-year old drug addict who had undergone splenectomy, developed hip joint infection during an episode of meningitis due to pneumococci. The germ was moderately sensitive to ampicillin. The second case involved the knee joint in a 29-year-old woman who developed pneumococcal pneumonia after a trip to Zaire. In both cases, joint infection developed after antibiotics had been initiated, and in the first case, after the infection appear to be under control. This would be similar to "post-infectious" arthritis described in gonococcal and meningococcal infections. In HIV positive patients, joint infections are rare compared with other types of immunodepression, but can be observed in all stages of the disease. A total of 75 cases have been reported in the literature, including 8 cases due to pneumococci. These joint infections could be another argument in favour of anti-pneumococcal vaccination in HIV positive patients.

    We questioned whether heightened impairment of regenerative capacity of osteoblasts might account for the excess of osteonecrosis and osteoporosis seen in HIV-infected patients. Were that the case, patients with osteonecrosis would have more osteoporosis than the patients without osteonecrosis. Eleven thousand, five hundred and six patients with HIV infection were studied for the presence of osteonecrosis and osteoporosis and for confounding factors. Depending upon whether dual-energy X-ray absorptiometry (DEXA) was before or after the diagnosis of osteonecrosis, osteoporosis was between 6.3 and 18 times more frequent in those with than in those without osteonecrosis. Those who received DEXA were similar to those who did not in median CD4 level at the time of DEXA or at a comparable time after their first recorded CD4 cell count in our system; in nadir CD4 level; and in use and amount of corticosteroids. Those with osteonecrosis and osteoporosis did not use more corticosteroids than those with osteoporosis without osteonecrosis. Alcohol abuse had not been diagnosed more often before the occurrence of osteonecrosis than in those without osteonecrosis. Tenofovir was not more used by those with than by those without osteoporosis. Osteonecrosis and osteoporosis in HIV-infected patients were concurrent more often than expected.

    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.

    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.

    The U.S. Public Health Service and the Infectious Diseases Society of America recently updated the 1995 guidelines on prevention of opportunistic infections in HIV infected individuals. PCP prophylaxis has not been changed in the new guidelines. Primary prevention strategies for toxoplasmosis encephalitis are described. Preventive medication for tuberculosis is generally not recommended, especially for persons in high risk groups such as the homeless and injection drug users. Significant changes were made for the prevention of Mycobacterium avium complex (MAC), and guidelines were changed for preventing bacterial respiratory infections. Primary prophylaxis of most fungal infections is generally not recommended, but lifelong secondary prophylaxis is indicated for all deep seated fungal infections and CMV. Prevention of opportunistic infections in HIV patients has a significant impact on morbidity and mortality.

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.

    The objective of this study was to investigate if early syphilis infection affects markers of HIV infection; CD4 T cells and viral load (VL). A retrospective study was performed on 160 HIV-positive patients (111 receiving antiretroviral therapy [ART] and 49 without ART). Early syphilis diagnosis was made in HIV patients during their follow-up at the HIV/AIDS Unit at a Greek Dermatology and Venereology Unit. The patients' blood tests were available at the time of diagnosis, as well as before and 12 weeks after early syphilis diagnosis. CD4 T cell counts and VL levels were measured. It was found that syphilis infection had a negative impact on the CD4 T cell counts in both groups, with reduced CD4 T cell counts observed in 84.6% (99/111) and 79.5% (39/49) of patients receiving and not receiving ART, respectively. After treatment for syphilis, CD4 T cell counts returned to pre-treatment levels in most patients, especially those receiving ART. There was a slight and transient VL increase. Patients receiving ART had a 27% increase in VL, compared to 71.4% among patients not receiving ART. Although the VL increase was slight (41-14,000 copies/ml) in the group under treatment, 4-5% (5/111) patients did not return to pre-treatment levels. Moreover, viral mutations associated with treatment resistance were identified in these patients. Early syphilis accelerates and complicates the progression of HIV infection. Early diagnosis and treatment of syphilis may prevent infection-associated complications in most instances. Consequently, prevention of syphilis and other sexually transmitted infections is of great importance for patients infected with HIV. © The Author(s) 2016.

    2000-01-01

    A clinical studies were carried out on gastrointestinal diseases associated with HIV infection. During the 6 years between January 1993 and December 1998, 71 HIV infected cases visited to Yokohama Municipal Citizen's hospital, and 26 of them developed gastrointestinal complications during the course of their illness. They consisted of 24 males and 2 females, with the mean age of 44.7 years and the medial value of 42.5 years. Of the 26 patients, 21 were Japanese, and the remaining 5 were Southeast Asian. The mean CD4 count was 143/microliter and the medial value was 32/microliter at the time of development of complications. Gastrointestinal complications were esophageal candidiasis in 6 patients, cytomegalovirus (CMV) gastritis and gastric Kaposi's sarcoma in 1 patient each, amebiasis in 8 patients, infectious colitis in 11 patients, and asymptomatic pathogen carriers in 3 patients. Esophageal and gastric complications were common in patients with low count of CD4, and endoscopy was useful for diagnosis. Amebiasis developed even in patients with normal CD4 and was common in males with experience in homosexual contact. It seems that homosexual contact acquire not only HIV infection but also Entamoeba histolytica through sexual contact. Protozoan and acid-fast bacteria were detected at high rate in patients with infectious colitis and asymptomatic pathogen carriers. Besides food-born infections, imported infections were seen in foreign and Japanese patients who had traveled abroad. The gastrointestinal diseases associated with HIV infections for the most part were opportunistic infections or tumors but imported, food-born, and sexually transmitted infections were also observed. It seems necessary to take into consideration of varying background of patients in the treatment of gastrointestinal diseases associated with HIV infections.

    This cross-sectional, descriptive, correlational study performed a structured questionnaire survey of a Taiwan population of male prison inmates to determine the prevalence of sexually transmitted infections (STIs), intravenous drug users (IDUs), and drug abuse and to assess their knowledge of HIV/AIDS. The objective was to obtain data needed to control the spread of HIV. Out of 1000 questionnaires distributed, 908 valid questionnaires were returned. Inmates were classified into three groups: IDUs with HIV (13.5%), IDUs without HIV (49.3%), and non-IDUs without HIV (37.2%). A total of 115 (12.7%) inmates had contracted STIs other than HIV. Compared with inmates without HIV, those with HIV were more likely to have a junior high school education level or lower and a history of the following: employment as a blue-collar laborer, STI, unprotected sexual activity, and needle sharing during intravenous drug use. The longer they have used intravenous drugs, the higher the probability that they shared needles, and the more likely they contracted with HIV. Taiwanese male inmates had a low level of knowledge about safe sex and HIV transmission routes, except for sharing needles. The three groups did not significantly differ in HIV-related knowledge. Given the high percentage of IDU and HIV infection in male prison inmates in Taiwan, interventions are needed to educate this population in the increased risk of contracting HIV/AIDS associated with unsafe sex and needle sharing during illicit drug use. Such interventions are crucial for limiting the spread of HIV as this population reintegrates with the community. Copyright © 2012. Published by Elsevier B.V.

    Full Text Available This cross-sectional, descriptive, correlational study performed a structured questionnaire survey of a Taiwan population of male prison inmates to determine the prevalence of sexually transmitted infections (STIs, intravenous drug users (IDUs, and drug abuse and to assess their knowledge of HIV/AIDS. The objective was to obtain data needed to control the spread of HIV. Out of 1000 questionnaires distributed, 908 valid questionnaires were returned. Inmates were classified into three groups: IDUs with HIV (13.5%, IDUs without HIV (49.3%, and non-IDUs without HIV (37.2%. A total of 115 (12.7% inmates had contracted STIs other than HIV. Compared with inmates without HIV, those with HIV were more likely to have a junior high school education level or lower and a history of the following: employment as a blue-collar laborer, STI, unprotected sexual activity, and needle sharing during intravenous drug use. The longer they have used intravenous drugs, the higher the probability that they shared needles, and the more likely they contracted with HIV. Taiwanese male inmates had a low level of knowledge about safe sex and HIV transmission routes, except for sharing needles. The three groups did not significantly differ in HIV-related knowledge. Given the high percentage of IDU and HIV infection in male prison inmates in Taiwan, interventions are needed to educate this population in the increased risk of contracting HIV/AIDS associated with unsafe sex and needle sharing during illicit drug use. Such interventions are crucial for limiting the spread of HIV as this population reintegrates with the community.

    Full Text Available 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.

    The cognitive deficits associated with HIV-1 infection are thought to primarily reflect neuropathophysiology within the fronto-striato-thalamo-cortical circuits. Prospective memory (ProM) is a cognitive function that is largely dependent on prefronto-striatal circuits, but has not previously been examined in an HIV-1 sample. A form of episodic memory, ProM involves the complex processes of forming, monitoring, and executing future intentions vis-à-vis ongoing distractions. The current study examined ProM in 42 participants with HIV-1 infection and 29 demographically similar seronegative healthy comparison (HC) subjects. The HIV-1 sample demonstrated deficits in time- and event-based ProM, as well as more frequent 24-hour delay ProM failures and task substitution errors relative to the HC group. In contrast, there were no significant differences in recognition performance, indicating that the HIV-1 group was able to accurately retain and recognize the ProM intention when retrieval demands were minimized. Secondary analyses revealed that ProM performance correlated with validated clinical measures of executive functions, episodic memory (free recall), and verbal working memory, but not with tests of semantic memory, retention, or recognition discrimination. Taken together, these findings indicate that HIV-1 infection is associated with ProM impairment that is primarily driven by a breakdown in the strategic (i.e., executive) aspects of retrieving future intentions, which is consistent with a prefronto-striatal circuit neuropathogenesis.

    Chronic kidney disease (CKD) is a major cause of morbidity and mortality among individuals with HIV infection. Screening for proteinuria in HIV-infected children will help in early detection and treatment, and thus prevention and progression to CKD to end-stage kidney disease (ESRD). We screened 139 HIV-infected children aged 18 months to 18 years for proteinuria by urinary dipstick and confirmed by spot urine protein-to-creatinine ratio. If proteinuria was absent by the above methods, patients were screened for microalbuminuria by urinary albumin to creatinine ratio. We found proteinuria in 11.5% and microalbuminuria in 10.6% of our study population. The prevalence of proteinuria was higher in the advanced stages; 8.05% in stage 1, 12.12% in stage 2 and 26.32% in stages 3 + 4.

    To assess the covariates of alcohol abuse and the association between alcohol abuse, high-risk sexual behaviors and sexually transmitted infections (STIs). Two thousand and nineteen women aged 20 to 44 were randomly selected in a 2-stage sampling from the Moshi urban district of northern Tanzania. Participant's demographic and socio-economic characteristics, alcohol use, sexual behaviors, and STIs were assessed. Blood and urine samples were drawn for testing of human immunodeficiency virus, herpes simplex virus, syphilis, chlamydia, gonorrhea, trichomonas, and mycoplasma genitalium infections. Adjusted analyses showed that a history of physical (OR = 2.05; 95% CI: 1.06-3.98) and sexual violence (OR = 1.63; 95% CI: 1.05-2.51) was associated with alcohol abuse. Moreover, alcohol abuse was associated with number of sexual partners (OR = 1.66; 95% CI: 1.01-2.73). Women who abused alcohol were more likely to report STIs symptoms (OR = 1.61; 95% CI: 1.08-2.40). Women who had multiple sexual partners were more likely to have an STI (OR = 2.41; 95% CI: 1.46-4.00) compared to women with 1 sexual partner. There was no direct association between alcohol abuse and prevalence of STIs (OR = 0.86; 95% CI: 0.55-1.34). However, alcohol abuse was indirectly associated with STIs through its association with multiple sexual partners. The findings of alcohol abuse among physically and sexually violated women as well as the association between alcohol abuse and a history of symptoms of STIs and testing positive for STIs have significant public health implications. In sub-Saharan Africa, where women are disproportionately affected by the HIV epidemic screening for alcohol use should be part of comprehensive STIs and HIV prevention programs.

    We studied the association between HIV infection, antiretroviral medications, and the risk of spontaneous intracranial hemorrhage. We performed a cohort and nested case control study in an administrative database. We selected all HIV-positive individuals presenting between 1985 and 2007. Each HIV-positive subject was matched with 4 HIV-negative individuals. We used a Poisson regression model to calculate rates of intracranial hemorrhage according to HIV status. We conducted a case -control study nested within the cohort of HIV-positive individuals to look at the effect of antiretroviral medications. Odds ratios for antiretroviral exposure were obtained using conditional logistic regression. There were 7,053 HIV-positive and 27,681 HIV-negative subjects, representing 138,704 person-years. There were 49 incident intracranial hemorrhages, 29 in HIV-positive and 20 in HIV-negative individuals. The adjusted hazard ratio for intracranial hemorrhage in HIV-positive compared to HIV-negative patients was 3.28 (95% confidence interval [CI] 1.75-6.12). The effect was reduced to 1.99 (95% CI 0.92-4.31) in the absence of AIDS-defining conditions, and increased to 7.64 (95% CI 3.78-15.43) in subjects with AIDS-defining conditions. Hepatitis C infection, illicit drug or alcohol abuse, intracranial lesions, and coagulopathy were all strongly associated with intracranial hemorrhage (all P < .001). In the case control study, 29 cases of ICH in HIV-positive individuals were matched to 228 HIV-positive controls. None of the antiretroviral classes were associated with an increase in the odds ratio of intracranial hemorrhage. The risk of intracranial hemorrhage in HIV-positive individuals seems to be mostly associated with AIDS-defining conditions, other comorbidities, or lifestyle factors. No association was found between use of antiretroviral medications and intracranial hemorrhage. Copyright © 2013 National Stroke Association. Published by Elsevier Inc. All rights reserved.

  15. Gender vulnerabilities, spousal abuse and the incidence of HIV in Lesotho:a case for an integrative rights-based approach.

    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.

    Rising incidence rates of HIV and STIs (sexually transmitted infections) among MSM (men who have sex with men) in Germany since 2001 call for new approaches in medical prevention. The present study addresses appropriate parameters to identify those HIV-positive MSM who are at high risk for transmitting HIV and STIs. Over a two-year period, 223 HIV-positive MSM attending the HIV outpatient clinic at the University Medical Center Essen (Germany) were systematically surveyed with respect to their sexual behavior, substance abuse, and psychological well-being in the preceding year. Data analyzed included laboratory and clinical data from the time of the initial HIV diagnosis until January 2014. In HIV-positive MSM, a history of substance abuse, promiscuity, younger age, and known STIs was associated with a greater incidence of unprotected sexual intercourse and STIs. Apart from a detectable viral load, additional HIV-specific parameters associated with an increased HIV transmission risk included untreated HIV infection, adherence problems, changes in antiretroviral treatment over the preceding twelve months, known multiresistant HIV infection, and a higher CD 4 nadir. Despite routine quarterly monitoring of viral loads - the result thereof was communicated to patients - only 60 % of individuals assessed their HIV transmission risk correctly. In HIV-positive MSM, patient history and routine laboratory tests allow for the establishment of patient profiles that suggest sexual behavior associated with a high risk of HIV and STI transmission, thus offering new approaches for medical prevention. © 2017 Deutsche Dermatologische Gesellschaft (DDG).

    The aim of this study was to detect abnormalities in left ventricular myocardial function due to HIV (human immunodeficiency virus) infection without established cardiovascular disease. An echocardiogram was performed in 50 asymptomatic HIV-infected patients (age 41 ± 6 years, 64% male) and in 20 healthy individuals. Conventional echocardiography and pulsed tissue Doppler imaging (TDI) were performed according to the guidelines. The strain rate of the basal segments was obtained with color tissue Doppler and used to evaluate systolic strain rate (SRS), early diastolic strain rate (SRE) and late diastolic strain rate (SRA). Longitudinal, radial and circumferential strain were assessed by 2D speckle tracking. The mean duration of HIV infection was 10 ± 5 years, CD4 count was 579 ± 286 cells/mm³, 32% had detectable viral load, and 86% were under treatment. Of the HIV-infected patients, one had grade 1 diastolic dysfunction. The groups were not different except for E wave (HIV 0.72 ± 0.17 m/s vs. control 0.84 ± 0.16 m/s, p=0.01), longitudinal strain (-19.5 ± 1.9% vs. -21 ± 2%, p=0.005), SRS (-1.1 ± 0.28 s⁻¹ vs. -1.3 ± 0.28 s⁻¹, p=0.02) and SRE (1.8 ± 0.4 s⁻¹ vs. 2.2 ± 0.4 s⁻¹, p<0.001), but only SRS (p=0.03, 95% CI 0.036; 0.67) and SRE (p=0.001, 95% CI -0.599; -0.168) had independent value. In an HIV-infected population without established cardiovascular disease, myocardial deformation abnormalities can be detected with strain and strain rate, revealing markers of myocardial injury.

    Our objective was to describe the characteristics of acute and established HIV infections diagnosed in the Canadian province of British Columbia. Province-wide HIV testing and surveillance data were analyzed to inform recommendations for targeted use of screening algorithms to detect acute HIV infections. Acute HIV infection was defined as a confirmed reactive HIV p24 antigen test (or HIV nucleic acid test), a non-reactive or reactive HIV EIA screening test and a non-reactive or indeterminate Western Blot. Characteristics of unique individuals were identified from the British Columbia HIV/AIDS Surveillance System. Primary drug resistance and HIV subtypes were identified by analyzing HIV pol sequences from residual sera from newly infected individuals. From February 2006 to October 2008, 61 individuals met the acute HIV infection case definition, representing 6.2% of the 987 newly diagnosed HIV infections during the analysis period. Acute HIV infection cases were more likely to be men who have sex with men (crude OR 1.71; 95% CI 1.01-2.89], to have had a documented previous negative HIV test result (crude OR 2.89; 95% CI 1.52-5.51), and to have reported a reason for testing due to suspected seroconversion symptoms (crude OR 5.16; 95% CI 2.88-9.23). HIV subtypes and rates of transmitted drug resistance across all classes of drugs were similar in persons with both acute and established HIV infections. Targeted screening to detect acute HIV infection is a logical public health response to the HIV epidemic. Our findings suggest that acute HIV infection screening strategies, in our setting, are helpful for early diagnosis in men who have sex with men, in persons with seroconversion symptoms and in previously negative repeat testers.

    HIV infection of healthcare workers by injury is an important issue in the management and prophylaxis of HIV-related disease. To describe a case where a nurse has been HIV-1 infected by needle-stick whilst taking blood from a newborn with an unknown HIV infection. Virological, immunological and clinical analysis of a peculiar case of HIV transmission from newborn to nurse has been reported. The nurse has been infected by needle-stick injury whilst taking blood from a newborn with an unknown HIV infection. The delayed declaration of accident by nurse and the inaccurate medical management of pregnant woman determined the subsequent absence of correct prophylaxis measures and then the impossibility to tackle the HIV transmission. This case indicates that HIV serological screening of pregnant women and prompt accident notification by health-care workers represent basic preventive measures that should effectively tackle the spread of HIV infection.

    With the advent of high active antiretroviral therapy there was a significant improvement on HIV subjects survival. Thus, bone changes related to HIV became an important aspect of these individuals. HIV affects bone remodeling causing bone fragility. In addition, antiretroviral therapy may also negatively affect bone metabolism. Several studies describe an increased incidence of fractures in these patients when compared with controls without the disease. The European Society of AIDS (EACS), and other societies, have included guidance on management of osteoporosis in HIV-infected patients emphasizing the identification of patients with low bone mass. Supplementation of calcium and vitamin D and the use of alendronate in these individuals should be recommended on a case base.

    With the observation of the occurrence of the human immunodeficiency virus (HIV) infection among leprosy patients in our pilot study carried out in Tamil Nadu, South India, a case-control study was planned to explore whether HIV infection is a risk factor for leprosy and to understand the characteristics of HIV infection and high-risk behaviors among leprosy patients. We screened 556 patients and 1004 nonleprosy controls (matching 502 cases for age, sex and area of residence) for HIV-1 and HIV-2 antibodies. They also were interviewed for personal information on history of blood transfusion, intravenous drug abuse, high-risk sexual behavior, and sexually transmitted diseases. Of the 1019 total cases screened (of both pilot and extended studies), 5 were found to be position for HIV antibodies (HIV-1 = 4, HIV-2 = 1); of the 1019 nonleprosy controls, 6 were positive for HIV-1 antibodies. An analysis by odds ratio revealed no association between leprosy and HIV infection (OR = 0.824, 95% CI = 0.201-3.593). A strong association was found only between high-risk behavior and HIV infection (OR = 5.186, 95% CI = 1.717-15.667). However, unmarried, unmarried after 30 years of age, exposure to spouses of the leprosy patients, and a history of surgery were all observed to be significantly more common among leprosy patients than the controls.

  13. HIV accomplices and adversaries in macrophage infection.

    Cell surface and intracellular proteins in macrophages influence various steps in the life cycle of lentiviruses. Characterization of these restriction and/or cofactors is essential to understanding how macrophages become unwitting HIV hosts and in fact, can coexist with a heavy viral burden. Although many of the cellular pathways co-opted by HIV in macrophages mimic those seen in CD4+ T cells, emerging evidence reveals cellular constituents of the macrophage, which may be uniquely usurped by HIV. For example, in addition to CD4 and CCR5, membrane annexin II facilitates early steps in infection of macrophages, but not in T cells. Blockade of this pathway effectively diminishes macrophage infection. Viral binding engages a macrophage-centric signaling pathway and a transcriptional profile, including genes such as p21, which benefit the virus. Once inside the cell, multiple host cell molecules are engaged to facilitate virus replication and assembly. Although the macrophage is an enabler, it also possesses innate antiviral mechanisms, including apolipoprotein B mRNA-editing enzyme-catalytic polypeptide-like 3G (APOBEC3) family DNA-editing enzymes to inhibit replication of HIV. Differential expression of these enzymes, which are largely neutralized by HIV to protect its rebirth, is associated with resistance or susceptibility to the virus. Higher levels of the cytidine deaminases endow potential HIV targets with a viral shield, and IFN-alpha, a natural inducer of macrophage APOBEC expression, renders macrophages tougher combatants to HIV infection. These and other manipulatable pathways may give the macrophage a fighting chance in its battle against the virus.

    Full Text Available 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.

    Shame has been shown to predict sexual HIV transmission risk behavior, medication non-adherence, symptomatic HIV or AIDS, and symptoms of depression and PTSD. However, there remains a dearth of tools to measure the specific constructs of HIV-related and sexual abuse-related shame. To ameliorate this gap, we present a 31-item measure that assesses HIV and sexual abuse-related shame, and the impact of shame on HIV-related health behaviors. A diverse sample of 271 HIV-positive men and women who were sexually abused as children completed the HIV and Abuse Related Shame Inventory (HARSI) among other measures. An exploratory factor analysis supported the retention of three-factors, explaining 56.7% of the sample variance. These internally consistent factors showed good test–retest reliability, and sound convergent and divergent validity using eight well-established HIV specific and general psychosocial criterion measures. Unlike stigma or discrimination, shame is potentially alterable through individually-focused interventions, making the measurement of shame clinically meaningful. PMID:22065235

    There are roughly 30-40 million HIV-infected individuals in the world as of December 2007, and drug abuse directly contributes to one-third of all HIV infections in the United States. Antiretroviral therapy has increased the lifespan of HIV-seropositives, but CNS function often remains diminished, effectively decreasing quality of life. A modest proportion may develop HIV-associated dementia, the severity and progression of which is increased with drug abuse. HIV and drugs of abuse in the CNS target subcortical brain structures and DA systems in particular. This toxicity is mediated by a number of neurotoxic mechanisms, including but not limited to, aberrant immune response and oxidative stress. Therefore, novel therapeutic strategies must be developed that can address a wide variety of disparate neurotoxic mechanisms and apoptotic cascades. This paper reviews the research pertaining to the where, what, and how of HIV and cocaine/methamphetamine toxicity in the CNS. Specifically, where these toxins most affect the brain, what aspects of the virus are neurotoxic, and how these toxins mediate neurotoxicity.

    2005-04-01

    Insulin resistance, a risk factor for cardiovascular disease, is increasingly seen in persons infected with HIV. In those affected, it is unclear whether insulin resistance is a direct result of HIV infection alone; however, the development of insulin resistance has been established as a complication of antiretroviral therapies. Some protease inhibitors (PIs) are culpable, and there are significant differences in the impact of different PIs on glucose metabolism, with current evidence suggesting that atazanavir does not cause insulin resistance. The paucity of standardized laboratory tests makes early diagnosis of insulin resistance relatively elusive. Still, there are some clinically useful methods for assessing its presence. For prevention and/or treatment, exercise and optimal diet are useful, and metformin and rosiglitazone have been shown to improve insulin resistance. Changing an effective antiretroviral regimen to counter insulin resistance must be approached thoughtfully in carefully selected patients.

    2014-09-01

    HIV infection is commonly associated with emotional and cognitive disorders that recognize both causes of an organic nature (related to the virus itself) and non-organic factors (emotional stress resulting from HIV diagnosis, social stigma and continued risk behaviour such as alcohol or drug abuse). Most of the literature has focused attention on depressive disorder, the most common mental disorder in the HIV population. In our analysis we evaluated the presence of personality disorders and alexithymia in a group of patients seropositive for HIV through appropriate psychological tests. Our data revealed a close relationship between socio-emotional alienation, distorted body perception and the difficulty in relating with each other, which is perceived as threatening and judgmental; this concept takes us back to the social stigma that modifies the emotional communication of HIV patients. The illness is experienced as an outsider that modifies the body, imprisons the emotionalism and cannot be controlled. Such personality alterations stop the emotional communication, thereby developing alexithymia.

    Little is known about the epidemiology on human papillomavirus (HPV) infection among HIV-infected men in Korea. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among HIV-infected men in Korea. A single-center cross-sectional study was conducted with HIV-infected men in Korea. Participants completed a detailed sexual behavior risk factor questionnaire. Anal samples were collected for cytology and HPV genotyping. Factors associated with anal HPV infection were assessed using multivariable logistic regression, stratifying by sexual behaviour. A total of 201 HIV-infected men were included in the study: 133 were from men who have sex with men (MSM) and 68 from men who have sex with women (MSW). Any anal HPV infection was detected in 82.7% of HIV-infected MSM and in 51.5% of HIV- infected MSW (P HIV-infected MSM, higher number of lifetime male sex partners was significantly associated with any anal HPV infection, but age was a significant risk factor associated with anal HR-HPV infection. Anal HPV infection was highly prevalent in HIV-infected MSM in Korea, and also commonly found in HIV-infected MSW. In HIV-infected MSM, the significant risk factor for being infected with any HPV infection was lifetime number of male sexual partners, and with anal oncogenic HPV infection was age.

    2015-03-01

    The innate immune system plays a critical role in the control of viral infections. Although the mechanisms involved in sensing and response to viral pathogens has progressed tremendously in the last decade, an understanding of the innate antiviral response to human retroviruses lagged behind. Recent studies now demonstrate that human retroviruses such as human immunodeficiency virus type 1 (HIV-1) and human T-lymphotropic virus 1 (HTLV-1) trigger a type I interferon antiviral response through novel cytosolic sensors that detect DNA intermediates of reverse transcription; in addition, these early host-pathogen interactions may trigger cell death pathways depending on the activation state of the target cell. The purpose of this review is to summarize the recent progress in the understanding of innate immune sensing of human retroviruses. Innate immune sensing of HIV-1 and HTLV-1 is influenced by the target cell phenotype, viral replicative intermediates, and host restriction factors that limit retroviral replication. Macrophages and dendritic cells detect HIV-DNA intermediates, whereas CD4 T cells differentially sense HIV DNA depending on the level of T-cell activation. Furthermore, the structure of the viral capsid and interplay between innate DNA sensors and host restriction factors all contribute to the magnitude of the ensuing innate immune response. The interplay between HIV infection and the innate immune system has emerged as an important component of HIV pathogenesis, linked to both induction of innate immunity and stimulation of cell death mechanisms. Ultimately, an in-depth knowledge of the mechanisms of innate immune control of human retrovirus infection may facilitate the development of novel treatment strategies to control retrovirus-induced immunopathology.

    Full Text Available The intestinal microbiota consists of a qualitatively and quantitatively diverse range of microorganisms dynamically interacting with the host. It is remarkably stable with regard to the presence of microorganisms and their roles which, however, can be altered due to pathological conditions, diet composition, gastrointestinal disturbances and/or drug ingestion. The present review aimed at contributing to the discussion about changes in the intestinal microbiota due to HIV-1 infection, focusing on the triad infection-microbiota-nutrition as factors that promote intestinal bacterial imbalance. Intestinal microbiota alterations can be due to the HIV-1 infection as a primary factor or the pharmacotherapy employed, or they can be one of the consequences of the disease.

    Detecting recent HIV infections is important to evaluate incidence and monitor epidemic trends. We aimed to evaluate the diagnostic performance and accuracy of the avidity index (AI) for discriminating for recent HIV infections. We collected serum samples from HIV-1 positive individuals: A) with known date of infection (midpoint in time between last HIV-negative and first HIV-positive test); B) infected for >1 year. Samples were divided into two aliquots: one diluted with phosphate buffered saline (PBS) and the other with 1 M guanidine. Both aliquots were assayed by the Architect HIV Ag/Ab Combo 4th generation assay (Abbott). We compared AI found in recent (RI=HIV subtype had no impact on AI misclassifications. All individuals in group A reached the AI threshold of 0.80 within 24 months after seroconversion. The AI is an accurate serological marker for discriminating recent from established HIV infections and meets WHO requirements for HIV incidence assays.

    Integrated intervention strategies, appropriate to the specific socioeconomic context, are required to address the needs of the 18 million adults projected to be infected with the human immunodeficiency virus (HIV) by the year 2000. Such interventions must operate on two levels. The first is aimed at minimizing the devastating effects of HIV and acquired immunodeficiency syndrome (AIDS) on individuals, while the second is geared toward halting HIV transmission in populations. The median two-year survival time for people with AIDS had doubled from 10 months before 1987 to 20 months in 1990, primarily because of treatments such as zidovudine that slow down the rate of virus replication, but AIDS patients who survive longer develop more intractable opportunistic infections than in the past. Viral transmission throughout populations can be halted only through a comprehensive strategy that addresses agent, host, and environmental factors in a complementary manner. For example, whether or not high-risk individuals will be willing and able to adopt safer sex practices depends, in large part, on the social, economic, and psychological forces acting on and within those individuals. Finally, public attitudes toward sexuality, drug use, and racial discrimination comprise the moral context in which AIDS prevention strategies must be implemented. The mass media, which have already created public awareness of the problem and corrected many misconceptions, must continue to motivate individuals to adopt behavioral changes that reduce the risk of HIV infection.

    Route of administration is an important contributor to the adverse health consequences of prescription medication abuse. The current study examines characteristics associated with non-oral routes of administration among a large sample of prescription opioid abusers and explores needle-related human immunodeficiency virus (HIV) risk behaviors as well. In the study, 791 opioid abusers completed a one-time structured interview, including complete histories of illicit and prescription drug abuse and route of drug administration. The most common method of pill use was oral (91%), followed by intranasal (53.1%), injection (23.8%), and smoking (14.5%). The youngest prescription opioid abusers, ages 18-24, displayed significantly higher odds of using alternate routes of administration and of reusing nonsterile needles for injection. HIV prevention programming should be developed for young prescription opioid injectors.

    Potential simulators of premortem trauma present problems of misinterpretation and possible false accusations of caregivers. A case of unsuspected neonatal herpes is reported with associated perianal ecchymosis that raises the possibility of sexual abuse. The decedent was an 8-day-old newborn infant who was born by Cesarean section and treated for 5 days postdelivery for sepsis. The newborn infant was discharged home but returned 2 days later with probable sepsis and new onset of perianal hemorrhage. She died 1 day later with autopsy, revealing neonatal disseminated herpetic infection with early anal involvement consisting of microscopic ulcerations with leukocytoclastic-like vasculitis and rare viral cytopathic changes. These histological changes produced grossly appearing anal ecchymosis with an absence of typical herpetic vesiculopapular lesions, which simulated abusive trauma. This case highlights the importance of considering occult neonatal herpes with associated perianal ecchymosis when presented with possible abusive anal trauma in a newborn infant. © 2011 American Academy of Forensic Sciences.

    The literature contains variable reports on the causative organisms of osteomyelitis and septic arthritis in patients with injecting drug abuse and on the rate of oxacillin-resistant S aureus. It is important to have a clear notion of the organisms to initiate empiric antimicrobial therapy. We therefore determined the spectrum of organisms in bone and joint infections in patients who were injecting drug users. We retrospectively reviewed the medical records of 215 patients (154 male, 61 female) with a history of injecting drug abuse and concurrent bone and/or joint infection from 1998 to 2005. The mean age was 43 years (range, 23-83 years). Osteomyelitis was present in 127 of the 215 patients (59%), septic arthritis in 53 (25%), and both in 35 (16%). The lower extremity was most commonly involved (141 cases, 66%), with osteomyelitis of the tibia present in 70 patients (33%) and septic knee arthritis in 30 patients (14%). Cultures yielded predominately Gram-positive bacteria: Staphylococcus aureus in 52% and coagulase-negative Staphylococcus in 20%. The proportion of oxacillin-resistant S aureus among S aureus infections increased from 21% in 1998 to 73% in 2005. Gram-negative organisms were present in 19% of infections and anaerobes in 13%. Patients with osteomyelitis had a higher prevalence of polymicrobial infections (46% versus 15%), infections due to Gram-negative organisms (24% versus 9%), and anaerobic infections (19% versus 6%) compared to patients with septic arthritis. These findings suggest broad-spectrum empiric antibiotic therapy, including vancomycin, should be considered for bone and joint infections in patients with injecting drug abuse.

    An enzyme immunoassay (EIA) has been developed which detects antigen(s) (Ag) of the human immunodeficiency virus (HIV) in the serum of patients with the acquired immunodeficiency syndrome (AIDS), AIDS-related complex (ARC), and patients at high risk for HIV infection. The test has a sensitivity of approximately 50 pg/ml of HIV protein. The specificity of the assay was determined with various virus infected cell lines, normal human sera/plasma, and serum from patients not known to be at risk for HIV infection. No false-positive HIV-Ag results were seen. Sera from 69% of patients with AIDS were positive for HIV-Ag as were 46% of patients with ARC and 19% of asymptomatic, HIV-antibody-positive individuals. There were significant associations between the stage of HIV infection--ie, AIDS vs ARC vs asymptomatic--and the detection of HIV-Ag in serum (p less than 0.0001) and the lack of detection of antibody to HIV core Ag (p less than 0.0001). HIV-Ag was also found in the serum of two asymptomatic antibody-negative individuals who were at high risk for AIDS and who later developed HIV antibody. The presence of HIV-Ag in sera was confirmed by an inhibition procedure. Thus, HIV-Ag can be detected in the serum of infected individuals prior to antibody production and correlates with the clinical stage of HIV infection.

    The article contains the analysis of materials about HIV infection and the status of work on its early detection among soldiers. Currently, the figures have a tendency to stabilization, but there is an increase in the persantage of HIV-infected persons performing military service under the contract, as well as the actualization sexual way of infection. The insufficient effectiveness of the barrier screening during the laboratory examination of recruits may contribute the increase in the incidence of HIV infection. Have been reviewed the questions medical-diagnostic and medical-psychological support of HIV-infected soldiers. Been analyzed the social consequences of delays in seeking medical help of patients in this group, the opportunities and challenges of their dispensary observation. It was noted that early detection of HIV infection and proper medical and psychological support in the dynamics of pathological process helps to reduce the number of new cases and improve their outcomes and to reduce the period of efficiency recovery of military personnel.

  12. The Oral Bacterial Communities of Children with Well-Controlled HIV Infection and without HIV Infection.

    Directory of Open Access Journals (Sweden)

    Brittany E Goldberg

    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

    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.

    The purpose of this study was to examine the relationships between childhood abuse/neglect experiences (sexual abuse, physical abuse, emotional abuse, and child neglect) and adult life functioning among Methadone Maintenance Treatment Program (MMTP) drop-outs. 432 subjects who dropped out of MMTP were recruited in New York City in 1997-1999. Adult life functioning was measured by HIV drug and sex risk behaviors, Addiction Severity Index (ASI) composite scores, and depression. The chi(2) tests, t tests, correlation, and multiple logistic regressions were performed to examine the relationships between abuse experiences and adult life functioning. The prevalence of child abuse/neglect history was high among MMTP drop-outs: sexual abuse-36%; physical abuse-60%; emotional abuse-57%; child physical neglect-66%; all four experiences-25%. As assessed via ASI composite scores, those who had been abused in childhood had significantly more medical, legal, relationship, and psychological problems than those who had not. Overall, several significant associations were found between the abuse experiences and HIV risk behaviors. Those who had experienced child neglect were more likely to be HIV positive. In multivariate analyses, childhood physical abuse was a significant predictor of having multiple sex partners while depression was significantly related to injection drug use in adulthood (psexual abuse and HIV sex risk behavior (ptreatment programs that include specialized therapies for those who suffered childhood abuse and neglect experiences.

    In the HIV-infected population there is a high prevalence of psychiatric disorders, conditions that often coexist with drug and alcohol dependence. Symptoms associated with psychiatric disorders are frequently managed with benzodiazepines, a class of medication often abused. We examined whether HIV-infected patients were more likely to fill a benzodiazepine prescription than their uninfected counterparts using a privately insured, nationally representative sample receiving clinical care between January 2007 and December 2009. Odds ratios (OR) and 95% confidence intervals (CI) to quantify the likelihood of receiving a benzodiazepine were calculated using multivariate logistic regression models. We examined the presence of interaction between HIV infection and sex using backwards elimination and by comparing stratum-specific OR to identify clinically meaningful differences. Overall, 323,796 beneficiaries were included in the sample, of which 723 were HIV infected. Bivariate analyses showed that compared to the uninfected sample, HIV-infected patients were more likely to have filled a benzodiazepine prescription (24% vs. 19%) during the study period. HIV-infected patients were also more likely to be male (80% vs. 44%), black (21% vs. 7%) and have a diagnosis of depression (12% vs. 8%) or insomnia (6% vs. 3%) than were uninfected patients. Adjusted for other covariates, HIV infection was associated with an increase (OR): 1.68, 95% CI: 1.39, 2.02) in the likelihood of filling a benzodiazepine prescription. When stratified by sex, HIV-infected males were more likely (OR: 1.68, 95% CI: 1.05, 2.67) than uninfected males to fill a benzodiazepine prescription while there was no observed difference in the likelihood of filling a benzodiazepine prescription between HIV-infected and uninfected females (OR: 1.12, 95% CI: 0.73, 1.70). Our findings suggest that HIV-infected patients, particularly HIV-infected males, are more likely to fill benzodiazepine prescriptions than their

    Background Little is known about the epidemiology on human papillomavirus (HPV) infection among HIV-infected men in Korea. The objective of this study was to determine the prevalence, genotype distribution and risk factors associated with anal HPV infection among HIV-infected men in Korea. Methods A single-center cross-sectional study was conducted with HIV-infected men in Korea. Participants completed a detailed sexual behavior risk factor questionnaire. Anal samples were collected for cytology and HPV genotyping. Factors associated with anal HPV infection were assessed using multivariable logistic regression, stratifying by sexual behaviour. Results A total of 201 HIV-infected men were included in the study: 133 were from men who have sex with men (MSM) and 68 from men who have sex with women (MSW). Any anal HPV infection was detected in 82.7% of HIV-infected MSM and in 51.5% of HIV- infected MSW (P anal cytology was more commonly detected in MSM than MSW (42.9% vs.19.1%, P sex partners was significantly associated with any anal HPV infection, but age was a significant risk factor associated with anal HR-HPV infection. Conclusion Anal HPV infection was highly prevalent in HIV-infected MSM in Korea, and also commonly found in HIV-infected MSW. In HIV-infected MSM, the significant risk factor for being infected with any HPV infection was lifetime number of male sexual partners, and with anal oncogenic HPV infection was age. PMID:27548632

    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.

    Background Uganda's generalized HIV epidemic is well described, including an estimated adult male HIV prevalence in Kampala of 4.5%, but no data are available on the prevalence of and risk factors for HIV infection among men who have sex with men (MSM). Methodology/Principal Findings From May 2008 to February 2009, we used respondent-driven sampling to recruit MSM ≥18 years old in Kampala who reported anal sex with another man in the previous three months. We collected demographic and HIV-related behavioral data through audio computer-assisted self-administered interviews. Laboratory testing included biomarkers for HIV and other sexually transmitted infections. We obtained population estimates adjusted for the non-random sampling frame using RDSAT and STATA. 300 MSM were surveyed over 11 waves; median age was 25 years (interquartile range, 21–29 years). Overall HIV prevalence was 13.7% (95% confidence interval [CI] 7.9%–20.1%), and was higher among MSM ≥25 years (22.4%) than among MSM aged 18–24 years (3.9%, odds ratio [OR] 5.69, 95% CI 2.02–16.02). In multivariate analysis, MSM ≥25 years (adjusted OR [aOR] 4.32, 95% CI 1.33–13.98) and those reporting ever having been exposed to homophobic abuse (verbal, moral, sexual, or physical abuse; aOR 5.38, 95% CI 1.95–14.79) were significantly more likely to be HIV infected. Conclusions/Significance MSM in Kampala are at substantially higher risk for HIV than the general adult male population. MSM reporting a lifetime history of homophobic abuse are at increased risk of being HIV infected. Legal challenges and stigma must be overcome to provide access to tailored HIV prevention and care services. PMID:22693590

    Neutropenia frequently occurs in patients with Human immunodeficiency virus (HIV) infection. Causes for neutropenia during HIV infection are multifactoral, including the viral toxicity to hematopoietic tissue, the use of myelotoxic agents for treatment, complication with secondary infections and malignancies, as well as the patient’s association with confounding factors which impair myelopoiesis. An increased prevalence and severity of neutropenia is commonly seen in advanced stages of HIV disease. Decline of neutrophil phagocytic defense in combination with the failure of adaptive immunity renders the host highly susceptible to developing fatal secondary infections. Neutropenia and myelosuppression also restrict the use of many antimicrobial agents for treatment of infections caused by HIV and opportunistic pathogens. In recent years, HIV infection has increasingly become a chronic disease because of progress in antiretroviral therapy (ART). Prevention and treatment of severe neutropenia becomes critical for improving the survival of HIV-infected patients. PMID:24654626

    Full Text Available Suboptimal adherence, toxicity, drug resistance and viral reservoirs make the lifelong treatment of HIV infection challenging. The emerging field of nanotechnology may play an important role in addressing these challenges by creating drugs that possess pharmacological advantages arising out of unique phenomena that occur at the “nano” scale. At these dimensions, particles have physicochemical properties that are distinct from those of bulk materials or single molecules or atoms. In this review, basic concepts and terms in nanotechnology are defined, and examples are provided of how nanopharmaceuticals such as nanocrystals, nanocapsules, nanoparticles, solid lipid nanoparticles, nanocarriers, micelles, liposomes and dendrimers have been investigated as potential anti-HIV therapies. Such drugs may, for example, be used to optimize the pharmacological characteristics of known antiretrovirals, deliver anti-HIV nucleic acids into infected cells or achieve targeted delivery of antivirals to the immune system, brain or latent reservoirs. Also, nanopharmaceuticals themselves may possess anti-HIV activity. However several hurdles remain, including toxicity, unwanted biological interactions and the difficulty and cost of large-scale synthesis of nanopharmaceuticals.

    Evidence of a link between sexual violence and HIV is growing; however, studies among children are scarce. The authors sought to characterise child sexual abuse in Harare, Zimbabwe, and explore its links with HIV and orphanhood. Records for new clients attending a child sexual abuse clinic from July 2004 to June 2005 were computerised and reviewed. Information on characteristics, medical examinations, laboratory tests and perpetrators were summarised. Orphan prevalence was compared with Demographic and Health Survey (DHS) 2005/2006 data for Harare, and a household-based survey in a neighbouring community. Over 1 year, 1194 new clients (90% female) aged 7 weeks to 16 years were assessed, with 93% of boys and 59% of girls classified clinically as prepubertal. 94% of clients reported penetrative sexual abuse, occurring most often in the child's home. Most perpetrators were identified as relatives or neighbours by children under 12 years, and 'boyfriends' by adolescent girls. At presentation, 31/520 (6%) clients tested were HIV-positive. Where recorded, 39 (6%) clients presented within 3 days of abuse, and 36 were given postexposure prophylaxis for HIV (PEP). Among female clients, orphan prevalence was higher than in the DHS (OR=1.7; 1.4 to 2.2) and neighbouring community (OR=1.7; 0.7 to 4.3). High numbers of children in Harare experience penetrative sexual abuse, and most present too late for PEP. More immediate presentation of sexual abuse can help to prevent HIV and recurrent abuse, and assist in examination and prosecution. Orphanhood emerged as a possible risk factor for sexual abuse and an important area for further research.

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 caspase 8 cleavage by HIV-1 protease are coincident. Next we show that HIV-1 protease not only cleaves procaspase 8, producing Casp8p41, but also independently stimulates NF-kappaB activity. Finally, we demonstrate that the HIV protease cleavage of caspase 8 is necessary for optimal NF-kappaB activation and that the HIV-1 protease specific cleavage fragment Casp8p41 is sufficient to stimulate HIV-1 replication through NF-kappaB dependent HIV-LTR activation both in vitro as well as in cells from HIV infected donors. Consequently, the molecular events which promote death of HIV-1 infected T cells function dually to promote HIV-1 replication, thereby favoring the propagation and survival of HIV-1.

    The HIV surveillance system in Germany is based on mandatory, anonymous notification of newly diagnosed HIV cases by laboratories. Because the time between HIV infection and the diagnosis of HIV varies widely between persons, it is difficult to determine the number of cases of recent HIV infection among newly diagnosed cases of HIV. In Germany, the BED-capture-enzyme immunoassay (BED-CEIA) has been used to distinguish between recent and long-standing HIV infection. The aim of this analysis is to report the proportion of cases of recent HIV infection among newly diagnosed cases in Germany between 2008 and 2014 and to identify factors associated with recent infections. A sample of voluntary laboratories among all HIV diagnostic laboratories was recruited. Residual blood from HIV diagnostic tests was spotted on filter paper as dried serum or dried plasma spots and was sent along with the notification form of the HIV cases. The BED-CEIA test was performed. A case was defined as recent HIV infection with a BED-CEIA test result of less than 0.8 normalized optical density, with the exclusion of CDC stage C. The proportion of recent newly diagnosed HIV infections among different groups (such as transmission groups, gender or age groups) was calculated. We used logistic regression to identify factors associated with recent HIV infection and to identify subpopulations with high proportions of recent HIV infections. Approximately 10,257 newly diagnosed cases were tested for recency using the BED-CEIA. In total, 3084 (30.4%) of those were recently infected with HIV. The highest proportion of recent HIV infections was found among men who had sex with men (MSM) (35%) and persons between 18 and 25 years of age (43.0%). Logistic regression revealed that female German intravenous drug users with a recent HIV infection had a higher chance of being detected than German MSM (OR 2.27). Surveillance of recent HIV infection is a useful additional tool to monitor the HIV epidemic in

    Individuals who experience childhood sexual abuse (CSA) have higher rates of unsafe sexual behaviors and/or HIV or sexually transmitted infection (STI) incidence. Accordingly, sexual minorities also have higher rates of HIV/STI incidence compared with heterosexuals among those abused as children and those who were not. However, little is known concerning the mechanisms by which CSA confers increased sexual risk. Using data from the National Epidemiologic Survey on Alcohol and Related Conditions, we prospectively analyzed the relationship between CSA and recent incident HIV/STIs at wave 2 (2004-2005) while examining mental health and substance-use disorders reported during wave 1 (2001-2002) as putative mediators. For women, mental health disorders mediated 35% of the effect of CSA on the risk of HIV/STI. Neither alcohol nor drug-use disorders were mediators for HIV/STI risk because of CSA in women. For heterosexual men, mental health disorders (90%), alcohol (24%), and drug-use (46%) disorders mediated some or all of the HIV/STI risk. None of the disorders mediated the risk of HIV/STI in sexual minority men, who had the highest HIV/STI risk among the groups measured. CSA is a strong risk factor for risky sexual behavior in adulthood. Our findings indicate that there may be multiple causal pathways from CSA to HIV risk, with different mediators to be targeted for intervention. These differences need to be further studied to design appropriate HIV interventions to reduce the high-risk behaviors among individuals who were sexually abused as children.

    Dendritic cells have a central role in HIV infection. On one hand, they are essential to induce strong HIV-specific CD4+ helper T-cell responses that are crucial to achieve a sustained and effective HIV-specific CD8+ cytotoxic T-lymphocyte able to control HIV replication. On the other hand, DCs contribute to virus dissemination and HIV itself could avoid a correct antigen presentation. As the efficacy of immune therapy and therapeutic vaccines against HIV infection has been modest in the best...

    To review the presentation and management of child sexual abuse cases presenting to Queen Elizabeth Central Hospital (QECH), Blantyre, since the introduction of an HIV postexposure prophylaxis programme. Demographic and medical data was collected from all children presenting to Queen Elizabeth Central Hospital, Blantyre, Malawi between January 2005 and February 2007 with alleged child sexual abuse (CSA). Between January 2005 and February 2007, 217 children presented with alleged CSA. This an average of 3 more per month since the previous year, a 57 percent increase. Physical examination showed signs of trauma 60% (130/217) of cases. 63% (137/217) of the cases presented within 72 hours of defilement. Overall in 42% (92/217) of children a one month course of HIV PEP was indicated and given. In 58% (125/217) HIV PEP was not indicated in view of normal examination, presentation too late (>72 hrs after abuse), multiple abuse episodes in the last 6 months, HIV test positive or HIV test refused. In 66% (144/217) of assessed children antibiotic treatment was given for the prevention and/ or treatment of sexually transmitted infections (STIs). The introduction of an HIV PEP programme for victims of CSA has lead to increased numbers presenting and being treated. In conclusion it is likely that a significant number of children have been prevented from acquiring HIV and other STIs following CSA. The key area where our service needs to be improved is in establishing documented follow up of all cases to monitor medication compliance, side effects and rates of HIV seroconversion following CSA.

    Tuberculosis (TB) incidence has declined ∼1.5% annually since 2000, but continued to affect 10.4 million individuals in 2015, with 1/3 remaining undiagnosed or underreported. The diagnosis of TB among those co-infected with HIV is challenging as TB remains the leading cause of death in such individuals. Accurate and rapid diagnosis of active TB will avert mortality in both adults and children, reduce transmission, and assist in timeous decisions for antiretroviral therapy initiation. This review describes advances in diagnosing TB, especially among HIV co-infected individuals, highlights national program's uptake, and impact on patient care. The TB diagnostic landscape has been transformed over the last 5 years. Molecular diagnostics such as Xpert MTB/RIF, which simultaneously detects Mycobacterium tuberculosis (MTB) resistance to rifampicin, has revolutionized TB control programs. WHO endorsed the use of Xpert MTB/RIF in 2010 for use in HIV/TB co-infected patients, and later in 2013 for use as the initial diagnostic test for all adults and children with signs and symptoms of pulmonary TB. Line probe assays (LPAs) are recommended for the detection of rifampicin and isoniazid resistance in sputum smear-positive specimens and mycobacterial cultures. A second-line line probe assay has been recommended for the diagnosis of extensively drug-resistant (XDR)-TB Assays such as the urine lateral flow (LF)-lipoarabinomannan (LAM), can be used at the point of care (POC) and have a niche role to supplement the diagnosis of TB in seriously ill HIV-infected, hospitalized patients with low CD4 cell counts of less than 100 cells/μl. Polyvalent platforms such as the m2000 (Abbott Molecular) and GeneXpert (Cepheid) offer potential for integration of HIV and TB testing services. While the Research and Development (R&D) pipeline appears to be rich at first glance, there are actually few leads for true POC tests that would allow for earlier TB diagnosis or rapid, comprehensive

  7. A mathematical approach to HIV infection dynamics

    In order to obtain a comprehensive form of mathematical models describing nonlinear phenomena such as HIV infection process and AIDS disease progression, it is efficient to introduce a general class of time-dependent evolution equations in such a way that the associated nonlinear operator is decomposed into the sum of a differential operator and a perturbation which is nonlinear in general and also satisfies no global continuity condition. An attempt is then made to combine the implicit approach (usually adapted for convective diffusion operators) and explicit approach (more suited to treat continuous-type operators representing various physiological interactions), resulting in a semi-implicit product formula. Decomposing the operators in this way and considering their individual properties, it is seen that approximation-solvability of the original model is verified under suitable conditions. Once appropriate terms are formulated to describe treatment by antiretroviral therapy, the time-dependence of the reaction terms appears, and such product formula is useful for generating approximate numerical solutions to the governing equations. With this knowledge, a continuous model for HIV disease progression is formulated and physiological interpretations are provided. The abstract theory is then applied to show existence of unique solutions to the continuous model describing the behavior of the HIV virus in the human body and its reaction to treatment by antiretroviral therapy. The product formula suggests appropriate discrete models describing the dynamics of host pathogen interactions with HIV1 and is applied to perform numerical simulations based on the model of the HIV infection process and disease progression. Finally, the results of our numerical simulations are visualized and it is observed that our results agree with medical and physiological aspects.

    To investigate the associations between sexual abuse and human immunodeficiency virus (HIV)-related attitudes and behaviors of adolescents with a psychiatric disorder. HIV-related knowledge, attitudes, and behaviors were examined by self-report assessment of adolescents admitted to a psychiatric hospital (N = 100). A subsample (n = 30) completed a role-playing exercise regarding HIV-preventive behavior that was scored for the degree of effective communication by raters blind to the subjects' abuse history. HIV-related risk behaviors were prevalent, including unprotected sexual intercourse (67%) and multiple partners (27%) among the sexually active (71% of the total). Also frequent were alcohol and drug use (25%) and sharing cutting instruments (22%) among those engaged in self-cutting behavior (62%). The 38% of the sample identified as having a history of sexual abuse indicated significantly poorer self-efficacy concerning condom use than their peers. Abused females scored significantly lower on the self-efficacy of condom use scale and reported significantly more frequent alcohol use than nonabused females (p = .003). A hierarchical multiple regression that controlled for consistency of condom use and tolerance of people with acquired immunodeficiency syndrome found that abuse history uniquely accounted for 16% of the variance in condom use self-efficacy. Analysis of the videotaped role-play found that abused adolescents were significantly less competent and had more difficulty in effective communication than their peers (p = .003). A history of sexual abuse is associated with impaired safe sexual decision-making and HIV-preventive communication skills, even in this already at-risk group. This study also underscores the importance of actively addressing these issues in the context of clinical care.

    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.)

    Full Text Available Purpose: Several studies have shown that HIV patients are at higher risk of lung cancer. 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.

    Infection with human immunodeficiency virus type 2 (HIV-2) occurs mainly in West Africa, but an increasing number of cases have been recognized in Europe, India, and the United States. In this era of global integration, clinicians must be aware of when to consider the diagnosis of HIV-2 infection and how to test for this virus. Although there is debate regarding when therapy should be initiated and which regimen should be chosen, recent trials have provided important information on treatment options for HIV-2 infection. In this review, we present information on recent clinical advances in our understanding of HIV-2 infection and highlight remaining diagnostic and therapeutic challenges.

  13. Chronic HIV-1 infection frequently fails to protect against superinfection.

    2007-11-01

    Full Text Available Reports of HIV-1 superinfection (re-infection have demonstrated that the immune response generated against one strain of HIV-1 does not always protect against other strains. However, studies to determine the incidence of HIV-1 superinfection have yielded conflicting results. Furthermore, few studies have attempted to identify superinfection cases occurring more than a year after initial infection, a time when HIV-1-specific immune responses would be most likely to have developed. We screened a cohort of high-risk Kenyan women for HIV-1 superinfection by comparing partial gag and envelope sequences over a 5-y period beginning at primary infection. Among 36 individuals, we detected seven cases of superinfection, including cases in which both viruses belonged to the same HIV-1 subtype, subtype A. In five of these cases, the superinfecting strain was detected in only one of the two genome regions examined, suggesting that recombination frequently occurs following HIV-1 superinfection. In addition, we found that superinfection occurred throughout the course of the first infection: during acute infection in two cases, between 1-2 y after infection in three cases, and as late as 5 y after infection in two cases. Our results indicate that superinfection commonly occurs after the immune response against the initial infection has had time to develop and mature. Implications from HIV-1 superinfection cases, in which natural re-exposure leads to re-infection, will need to be considered in developing strategies for eliciting protective immunity to HIV-1.

    data, we tabulated it for each comparison. We assessed the certainty of the evidence using the GRADE approach. Main results We included 33 trials with 10,325 participants, of which 17 trials were new trials. Ten trials compared a daily multiple micronutrient supplement to placebo in doses up to 20 times the dietary reference intake, and one trial compared a daily standard dose with a high daily dose of multivitamins. Nineteen trials compared supplementation with single or dual micronutrients (such as vitamins A and D, zinc, and selenium) to placebo, and three trials compared different dosages or combinations of micronutrients. Multiple micronutrients We conducted analyses across antiretroviral therapy (ART)-naive adults (3 trials, 1448 participants), adults on antiretroviral therapy (ART) (1 trial, 400 participants), and ART-naive adults with concurrent active tuberculosis (3 trials, 1429 participants). Routine multiple micronutrient supplementation may have little or no effect on mortality in adults living with HIV (RR 0.91, 95% CI 0.72 to 1.15; 7 trials, 2897 participants, low certainty evidence). Routine supplementation for up to two years may have little or no effect on the average of mean CD4+ cell count (MD 26.40 cells/mm³, 95% CI −22.91 to 75.70; 6 trials, 1581 participants, low certainty evidence), or the average of mean viral load (MD −0.1 log10viral copies, 95% CI −0.26 to 0.06; 4 trials, 840 participants, moderate certainty evidence). One additional trial in ART-naïve adults did report an increase in the time to reach a CD4+ cell count HIV. Larger trials might reveal small but important effects. These findings should not be interpreted as a reason to deny micronutrient supplements for people living with HIV where specific deficiencies are found or where the person's diet is insufficient to meet the recommended daily allowance of vitamins and minerals.

    : The impact of antiretroviral therapy (ART) on the size of the HIV reservoir has implications for virological remission in adults, but is not well characterized in perinatally acquired infection. In a prospective observational study of 20 children with perinatally acquired infection and sustained viral suppression on ART for more than 5 years, proviral DNA was significantly higher in deferred (>4 years) versus early (first year of life) ART recipients (P = 0.0062), and correlated with age of initiation (P = 0.13; r = 0.57). No difference was seen in cell-associated viral RNA (P = 0.36). Identifying paediatric populations with smaller reservoirs may inform strategies with potential to induce ART-free remission.

  17. Astrocytes Resist HIV-1 Fusion but Engulf Infected Macrophage Material

    Rebecca A. Russell

    2017-02-01

    Full Text Available HIV-1 disseminates to diverse tissues and establishes long-lived viral reservoirs. These reservoirs include the CNS, in which macrophage-lineage cells, and as suggested by many studies, astrocytes, may be infected. Here, we have investigated astrocyte infection by HIV-1. We confirm that astrocytes trap and internalize HIV-1 particles for subsequent release but find no evidence that these particles infect the cell. Astrocyte infection was not observed by cell-free or cell-to-cell routes using diverse approaches, including luciferase and GFP reporter viruses, fixed and live-cell fusion assays, multispectral flow cytometry, and super-resolution imaging. By contrast, we observed intimate interactions between HIV-1-infected macrophages and astrocytes leading to signals that might be mistaken for astrocyte infection using less stringent approaches. These results have implications for HIV-1 infection of the CNS, viral reservoir formation, and antiretroviral therapy.

    Childhood sexual and physical abuse have been linked to adolescent and adult risky sexual behaviors, including early sexual debut, an increased number of sexual partners, unprotected sex, alcohol and drug use during sex and sexual violence. This paper explores these relationships among both men and women who report histories of childhood abuse from representative samples of communities in three countries in southern and eastern Africa (South Africa, Zimbabwe and Tanzania). Data were collected as part of a 3-year randomized community trial to rapidly increase knowledge of HIV status and to promote community responses through mobilisation, mobile testing, provision of same-day HIV test results and post-test support for HIV. The results indicate that reported childhood sexual and physical abuse is high in all three settings, also among men, and shows strong relationships with a range of sexual risk behaviors, including age at first sex (OR -0.6 (CI: -0.9, -0.4, p abused in childhood comprise between 6 and 29 % of young adult men and women living in these African settings and constitute a population at high risk of HIV infection.

    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.

    Human immunodeficiency virus (HIV) is a fast replicating ribonucleic acid virus, which can easily mutate in order to escape the effects of drug administration. Hence, understanding the basic mechanisms underlying HIV persistence in the body is essential in the development of new therapies that could eradicate HIV infection. Lymphoid tissues are the primary sites of HIV infection. Despite the recent progress in real-time monitoring technology, HIV infection dynamics in a whole body is unknown. Mathematical modeling and simulations provide speculations on global behavior of HIV infection in the lymphatic system. We propose a new mathematical model that describes the spread of HIV infection throughout the lymphoid tissue network. In order to represent the volume difference between lymphoid tissues, we propose the proportionality of several kinetic parameters to the lymphoid tissues' volume distribution. Under this assumption, we perform extensive numerical computations in order to simulate the spread of HIV infection in the lymphoid tissue network. Numerical computations simulate single drug treatments of an HIV infection. One of the important biological speculations derived from this study is a drug saturation effect generated by lymphoid network connection. This implies that a portion of reservoir lymphoid tissues to which drug is not sufficiently delivered would inhibit HIV eradication despite of extensive drug injection.

    Full Text Available HIV infection remains a pandemic and a leading cause of morbidity and mortality particularly in sub Sahara Africa. Although highly active antiretroviral therapy has brought about a marked reduction in morbidity and mortality, there are growing concerns on increasing non-communicable complications particularly cardiovascular and metabolic diseases in HIV disease. The objective was to do a systematic review of the clinical entities and pathogenesis of cardiovascular diseases and metabolic syndrome in HIV disease. The result shows that HIV infection and the resultant chronic immune activation; HAAR; opportunistic infections and some of the drugs use for them; and traditional cardiovascular risk factors are some of the conditions associated with cardiovascular diseases and metabolic syndrome in HIV infection. Standard cardiovascular disease screening and risk-reducing interventions should be routinely undertaken for HIV-infected persons. [Archives Medical Review Journal 2013; 22(3.000: 377-392

    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.

    Yellow fever (YF) is an acute viral haemorrhagic disease prevalent in tropical Africa and Latin America. The World Health Organization (WHO) estimates that there are 200,000 cases of YF and 30,000 deaths worldwide annually. Treatment for YF is supportive, but a live attenuated virus vaccine is effective for preventing infection. WHO recommends immunisation for all individuals > 9 months living in countries or areas at risk. However, the United States Advisory Committee on Immunization Practices (ACIP) advises that YF vaccine is contraindicated in individuals with HIV. Given the large populations of HIV-infected individuals living in tropical areas where YF is endemic, YF vaccine may be an important intervention for preventing YF in immunocompromised populations. To assess the risk and benefits of YF immunisation for people infected with HIV. We used standard Cochrane methods to search electronic databases and conference proceedings with relevant search terms without limits to language. Randomised controlled trials and cohort studies of individuals with HIV infection who received YF vaccine (17DD or 17D-204). Two authors screened abstracts of references identified by electronic or bibliographic searches according to inclusion and exclusion criteria as detailed in the protocol. We identified 199 references and examined 19 in detail for study eligibility. Data were abstracted independently using a standardised abstraction form. Three cohort studies were included in the review. They examined 484 patients with HIV infection who received YF immunisation. Patients with HIV infection developed significantly lower concentrations of neutralising antibodies in the first year post immunisation compared to uninfected patients, though decay patterns were similar for recipients regardless of HIV infection. No study patient with HIV infection suffered serious adverse events as a result of YF vaccination. YF vaccination can produce protective levels of neutralising antibodies in

    Full Text Available Tuberculosis (TB has emerged as the most prominent bacterial disease found in human immunodeficiency virus (HIV-positive individuals worldwide. Due to high prevalence of asymptomatic Mycobacterium tuberculosis (Mtb infections, the future HIV vaccine in areas highly endemic for TB will often be administrated to individuals with an ongoing Mtb infection. The impact of concurrent Mtb infection on the immunogenicity of a HIV vaccine candidate, MultiHIV DNA/protein, was investigated in mice. We found that, depending on the vaccination route, mice infected with Mtb before the administration of the HIV vaccine showed impairment in both the magnitude and the quality of antibody and T cell responses to the vaccine components p24Gag and gp160Env. Mice infected with Mtb prior to intranasal HIV vaccination exhibited reduced p24Gag-specific serum IgG and IgA, and suppressed gp160Env-specific serum IgG as compared to respective titers in uninfected HIV-vaccinated controls. Importantly, in Mtb-infected mice that were HIV-vaccinated by the intramuscular route the virus neutralizing activity in serum was significantly decreased, relative to uninfected counterparts. In addition mice concurrently infected with Mtb had fewer p24Gag-specific IFN-γ-expressing T cells and multifunctional T cells in their spleens. These results suggest that Mtb infection might interfere with the outcome of prospective HIV vaccination in humans.

    Diverticulitis in patients on immunosuppressant therapy has been associated with increased mortality, but there are no data for HIV-infected patients. Our aim was to compare the outcomes of hospitalizations for diverticulitis in patients with and without HIV infection. Cross-sectional study of hospitalizations in the United States accessed through the Nationwide Inpatient Sample, Healthcare Cost and Utilization Project. Patients hospitalized for diverticulitis in 2007-2011 were included in the analysis. The primary outcomes of interest were mortality and surgical therapy rates. Patients from 2003 to 2011 were utilized to analyse trends in prevalence. There were 2375 patients with HIV infection hospitalized for diverticulitis and 1 160 391 patients without HIV infection hospitalized for diverticulitis from 2007 to 2011. The patients with HIV infection were younger and more likely to be male and nonwhite (P diverticulitis and HIV infection had a significantly increased in-hospital mortality rate [odds ratio (OR) 3.94 (95% confidence interval, CI, 1.52-10.20)] and a lower rate of surgical intervention [OR 0.74 (95% CI 0.57-0.95)]. From 2003 to 2011, there was a linear increasing trend in the prevalence of HIV infection among patients hospitalized for diverticulitis (P diverticulitis had increased mortality and received less surgical treatment in comparison to the general population.

    Full Text Available Backgrоund. HIV infected patients are at risk for vaccine-preventable infections such as tetanus and diphtheria. It is important to know about the protection of HIV-infected children from these infections, as there is a risk even after complete immunization. The protective immunity after vaccination against diphtheria and tetanus is measured by the antibodies level against these pathogens. The aim of this study was to evaluate the persistence of immunity to tetanus and diphtheria toxoid in HIV-infected children. Materials and methods. The protective immunity against diphtheria and tetanus was studied in children with HIV infection in the Kyiv City AIDS Center. Immunization rate was evaluated in 142 HIV-infected children. Serum samples were obtained in 59 HIV-infected children (study group vaccinated against diphtheria and tetanus toxoid during routine check-ups. The results of anti-tetanus and anti-diphtheria antibodies were compared with the data of 17 children without HIV (the control group.

    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

    Data on sexually transmitted infections (STI) prevalence among HIV-infected women in Thailand are limited. We studied, among HIV-infected women, prevalence of STI symptoms and signs; prevalence and correlates of having any STI; prevalence and correlates of Chlamydia trachomatis (CT) or Neisseria gonorrhoeae (GC) among women without CT and/or GC symptoms or signs; and number of women without CT and/or GC symptoms or signs needed to screen (NNS) to detect one woman with CT and/or GC overall, among pregnant women, and among women ≤25 years. During October 2004-September 2006, HIV-infected women at 3 obstetrics and gynecology clinics were asked about sexual behaviors and STI symptoms, physically examined, and screened for chlamydia, gonorrhea, trichomoniasis, and syphilis. Multivariate logistic regression was used to identify correlates of infections. NNS was calculated using standard methods. Among 1,124 women, 526 (47.0%) had STI symptoms or signs, 469 (41.7%) had CT and/or GC symptoms or signs, and 133 (11.8%) had an STI. Correlates of having an STI included pregnancy and having STI signs. Among 469 women and 655 women with vs. without CT and/or GC symptoms or signs, respectively, 43 (9.2%) vs. 31 (4.7%), 2 (0.4%) vs. 9 (1.4%), and 45 (9.6%) vs. 38 (5.8%) had CT, GC, or "CT or GC", respectively; correlates included receiving care at university hospitals and having sex with a casual partner within 3 months. NNS for women overall and women ≤25 years old were 18 (95% CI, 13-25) and 11 (95% CI, 6-23), respectively; and for pregnant and non-pregnant women, 8 (95% CI, 4-24) and 19 (95% CI, 14-27), respectively. STI prevalence among HIV-infected women, including CT and GC among those without symptoms or signs, was substantial. Screening for CT and GC, particularly for pregnant women, should be considered.

    Both HIV and HBV infection have become major health problems, of global concern, due to the high prevalence in the past few decades. Data from cumulated epidemiological surveys have shown the links between maternal HIV or HBV infection and adverse outcomes on pregnancy. Maternal HIV or HBV infection may also increase the mother-to-child (MTCT) transmission of the two diseases. However, association between HIV-HBV co-infection and adverse pregnancy is still inconclusive. Does maternal HIV-HBV co-infection have an impact on mother-to-child transmission on either HIV or HBV? Study on effective precautionary measures to promote both maternal and child's health is deemed necessary.

Statistics included multivariate linear regression and longitudinal linear mixed effects models.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.

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.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.

    Full Text Available Abstract Background A complex interaction exists between tuberculosis (TB and human immunodeficiency virus (HIV infection at an individual and community level. Limited knowledge about the rate of HIV infection in TB patients and the general population compromises the planning, resource allocation and prevention and control activities. The aim of this study was to determine the rate of HIV infection in TB patients and its correlation with the rate HIV infection in pregnant women attending antenatal care (ANC in Southern Ethiopia. Methods All TB patients and pregnant women attending health institutions for TB diagnosis and treatment and ANC were consecutively enrolled in 2004 – 2005. TB diagnosis, treatment and HIV testing were done according to the national guidelines. Blood samples were collected for anonymous HIV testing. We used univariate and multivariate logistic regression analysis to determine the risk factors for HIV infection and linear regression analysis to determine the correlation between HIV infection in TB patients and pregnant women. Results Of the 1308 TB patients enrolled, 226 (18% (95%CI: 15.8 – 20.0 were HIV positive. The rate of HIV infection was higher in TB patients from urban 25% (73/298 than rural areas 16% (149/945 [AOR = 1.78, 95%CI: 1.27–2.48]. Of the 4199 pregnant women attending ANC, 155 (3.8% [95%CI: 3.2–4.4] were HIV positive. The rate of HIV infection was higher in pregnant women from urban (7.5% (80/1066 than rural areas (2.5% (75/3025 [OR = 3.19, 95% CI: 2.31–4.41]. In the study participants attending the same health institutions, the rate of HIV infection in pregnant women correlated with the rate of HIV infection in TB patients (R2 = 0.732. Conclusion The rate of HIV infection in TB patients and pregnant women was higher in study participants from urban areas. The rate of HIV infection in TB patients was associated with the prevalence of HIV infection in pregnant women attending ANC.

    Infection rate among intravenous drug users (IDU) is higher than the general public, and is the major cause of morbidity and hospitalization in the IDU population. Epidemiologic studies provide data on increased prevalence of opportunistic bacterial infections such as TB and pneumonia, and viral infections such as HIV-1 and hepatitis in the IDU population. An important component in the intravenous drug abuse population and in patients receiving medically indicated chronic opioid treatment is opioid withdrawal. Data on bacterial virulence in the context of opioid withdrawal suggest that mice undergoing withdrawal had shortened survival and increased bacterial load in response to Salmonella infection. As the body of evidence in support of opioid dependency and its immunosuppressive effects is growing, it is imperative to understand the mechanisms by which opioids exert these effects and identify the populations at risk that would benefit the most from the interventions to counteract opioid immunosuppressive effects. Thus, it is important to refine the existing animal model to closely match human conditions and to cross-validate these findings through carefully controlled human studies. Better understanding of the mechanisms will facilitate the search for new therapeutic modalities to counteract adverse effects including increased infection rates. This review will summarize the effects of morphine on innate and adaptive immunity, identify the role of the mu opioid receptor in these functions and the signal transduction activated in the process. The role of opioid withdrawal in immunosuppression and the clinical relevance of these findings will also be discussed.

The aim of this study was to assess the impact of HIV types on mortality among TB patients in Guinea-Bissau and to examine the predictive ability of the TBscoreII, a clinical score used to assess disease severity. In a prospective follow-up study, we examined the prevalence of HIV-1, HIV-2, and HIV-1+2 co-infection in TB patients in Guinea-Bissau, and the impact on outcomes at 12 months of follow-up. We included all adult TB patients in an observational TB cohort at the Bandim Health Project (BHP) in Guinea-Bissau between 2003 and 2013 and assessed survival status at 12 months after the start of treatment. A total 1312 patients were included; 499 (38%) were female (male/female ratio 1.6). Three hundred and seventy-nine patients were HIV-infected: 241 had HIV-1, 93 had HIV-2, and 45 were HIV-1+2 dual infected. The HIV type-associated risk of TB was 6-fold higher for HIV-1, 7-fold higher for HIV-1+2 dual infection, and 2-fold higher for HIV-2 compared with the HIV-uninfected. Of the patients included, 144 (11%) died, 62 (12%) among females and 82 (9%) among males (hazard ratio (HR) 0.91, 95% confidence interval (CI) 0.64-1.30; p=0.596). Compared to male patients, female patients were younger (1 year younger, 95% CI 0.5-2; p=0.04), reported a longer duration of symptoms (14 days longer, 95% CI 4-25; p=0.003), and had a higher TBscoreII (0.5 points more, 95% CI 0.3-0.7; pHIV-infected (36% vs. 25%; pHIV infection increased the mortality risk, with HIV-1 infection displaying the highest HR (5.0, 95% CI 3.5-7.1), followed by HIV-1+2 (HR 4.2, 95% CI 2.2-7.8) and HIV-2 (HR 2.1, 95% CI 1.2-3.8). A TBscoreII ≥4 was associated with increased mortality (HR 2.2, 95% CI 1.5-3.1). Significantly increased HRs were found for signs of wasting; a BMI HIV type-associated risk of TB was much higher for HIV-1 patients and higher but

    The nature of tuberculosis (TB), being one of the most common opportunistic infections, is different among HIV-infected patients than HIV-negative patients. A retrospective study was conducted on HIV-positive and HIV-negative patients with new TB pleural effusion who were admitted to the National Research Institute of Tuberculosis and Lung Diseases in Tehran, Iran from 2005 to 2012. The two groups were compared with respect to clinical, imaging, mycobacteriologic and histopathologic characteristics of TB pleural effusion. In all, 42 HIV-positive and 132 HIV-negative cases of TB pleural effusion were included. Bilateral pleural effusion was statistically more common in the HIV-positive group (p = 0.004, OR = 3.81, 95% CI: 1.46-9.94) without any correlation with CD4 cell count. Pulmonary infiltration was found in 81% of HIV-positive and 49.2% of HIV-negative patients (p = 0.001, OR = 4.38, 95% CI: 1.88-10.1). Mycobacteriologic studies led to the diagnosis of TB in 66.6% of HIV-infected and 49.2% of HIV-negative patients. In 23.8% of HIV-positive and 50.7% of HIV-negative patients TB was ultimately diagnosed by pleural biopsy. HIV remained significantly associated with positive culture of pleural fluid in multivariate analysis. The diagnostic approach to TB pleural effusion in HIV-infected patients may be different. The diagnostic yield of mycobacteriologic studies was higher among HIV-positive patients, which may help in reducing the need for invasive procedures like pleural biopsy. © The Author(s) 2015.

    OBJECTIVE: The authors examined the separate and combined effects of methamphetamine dependence and HIV infection on brain morphology. METHOD: Morphometric measures obtained from magnetic resonance imaging of methamphetamine-dependent and/or HIV-positive participants and their appropriate age......- and education-matched comparison groups were analyzed. Main effects of age, HIV infection, methamphetamine dependence, and the interactions of these factors were examined in analyses of cerebral gray matter structure volumes. RESULTS: Independent of the effect of age, HIV infection was associated with reduced...... volumes of cortical, limbic, and striatal structures. There was also some evidence of an interaction between age and HIV infection such that older HIV-positive participants suffered disproportionate loss. Methamphetamine dependence was surprisingly associated with basal ganglia and parietal cortex volume...

    Human immunodeficiency virus (HIV) mortality is used as a key measure to monitor the impact of HIV throughout the world. It is important that HIV be correctly recorded on death certificates so that the burden of HIV mortality can be tracked accurately. The objective of this study was to determine the extent of failure to correctly report HIV on death certificates and examine patterns of incompleteness by demographic factors. Causes of death on death certificates of people infected with HIV reported to the Florida HIV surveillance system 2000-2011 were analyzed to determine the proportion without mention of HIV who had an underlying cause of death suggestive of HIV based on World Health Organization recommendations. Of the 11,989 deaths, 8089 (67.5%) had an HIV code (B20-B24, R75) as any of the causes of death, 3091 (25.8%) had no mention of HIV and the underlying cause was not suggestive of HIV, and 809 (6.7%) had no mention of HIV but the underlying cause was suggestive of HIV. Therefore, 9.1% (809/8898) of probable HIV-related deaths had no mention of HIV on the death certificate. Dying within 1 month of HIV diagnosis was the factor most strongly associated with no mention of HIV when the underlying cause was suggestive of HIV on the death certificate. The results suggest that HIV mortality using only vital records may underestimate actual HIV mortality by approximately 9%. Efforts to reduce incompleteness of reporting of HIV on death certificates could improve HIV-related mortality estimates.

    We assessed the prevalence of tuberculosis (TB) human immunodeficiency virus (HIV) co-infection and identified risk factors for HIV infection in smear-positive TB patients diagnosed by the TB programme in Eritrea. Of 365 notified TB patients, 220 (60.3%) could be traced and provided a blood sample that was tested. Of these, 26 (11.8%, 95%CI 7.6-16.1) were HIV-infected. Risk factors were age, urban residence and schooling level. The data indicate that, starting with the urban areas, it is time for Eritrea to introduce HIV testing of all TB patients.

    Full Text Available Introduction: As HIV-infected patients get older more non-AIDS-related malignancies are to be seen. Cancer now represents almost one third of all causes of deaths among HIV-infected patients (1. Albeit bladder cancer is one of the most common malignancy worldwide (2, only 13 cases of bladder cancer in HIV-infected patients have been reported in the literature so far (3. Materials and Methods: We conducted a monocentric study in our hospital. We selected all patients who were previously admitted (from 1998 to 2013 in our hospital with diagnoses of HIV and bladder cancer. The objective was to assess the prevalence and characteristics of bladder cancers in HIV-infected patients in our hospital. Results: Based on our administrative HIV database (6353 patients, we found 15 patients (0.2% with a bladder cancer. Patients’ characteristics are presented in Table 1. Patients were mostly men and heavy smokers. Their median nadir CD4 cell count was below 200 and most had a diagnosis of AIDS. A median time of 14 years was observed in those patients, between the diagnosis of HIV-infection and the occurrence of bladder cancer, although in patients much younger (median age 56 than those developing bladder cancer without HIV infection (71.1 years (4. Haematuria was the most frequent diagnosis circumstance in HIV-infected patients who had relatively preserved immune function on highly active antiretroviral therapy (HAART. Histopathology showed relatively advanced cancers at diagnosis with a high percentage of non transitional cell carcinoma (TCC tumor and of TCC with squamous differentiation, suggesting a potential role for human papilloma virus (HPV co-infection. Death rate was high in this population. Conclusions: Bladder cancers in HIV-infected patients remain rare but occur in relatively young HIV-infected patients with a low CD4 nadir, presenting with haematuria, most of them being smokers, and have aggressive pathological features that are associated with

    Full Text Available Abstract Background The instability faced by refugees may place them at increased risk of exposure to HIV infection. Nakivale Refugee Settlement in southwestern Uganda hosts 68,000 refugees from 11 countries, many with high HIV prevalence. We implemented an HIV screening program in Nakivale and examined factors associated with new HIV diagnosis. Methods From March 2013-November 2014, we offered free HIV screening to all clients in the Nakivale Health Center while they waited for their outpatient clinic visit. Clients included refugees and Ugandan nationals accessing services in the settlement. Prior to receiving the HIV test result, participants were surveyed to obtain demographic information including gender, marital status, travel time to reach clinic, refugee status, and history of prior HIV testing. We compared variables for HIV-infected and non-infected clients using Pearson’s chi-square test, and used multivariable binomial regression models to identify predictors of HIV infection. Results During the HIV screening intervention period, 330 (4% of 7766 individuals tested were identified as HIV-infected. Refugees were one quarter as likely as Ugandan nationals to be HIV-infected (aRR 0.27 [0.21, 0.34], p < 0.0001. Additionally, being female (aRR 1.43 [1.14, 1.80], p = 0.002 and traveling more than 1 h to the clinic (aRR 1.39 [1.11, 1.74], p = 0.003 increased the likelihood of being HIV-infected. Compared to individuals who were married or in a stable relationship, being divorced/separated/widowed increased the risk of being HIV-infected (aRR 2.41 [1.88, 3.08], p < 0.0001, while being single reduced the risk (aRR 0.60 [0.41, 0.86], p < 0.0001. Having been previously tested for HIV (aRR 0.59 [0.47, 0.74], p < 0.0001 also lowered the likelihood of being HIV-infected. Conclusions In an HIV screening program in a refugee settlement in Uganda, Ugandan nationals are at higher risk of having HIV than refugees. The high HIV

    This study estimated prevalence of HIV risk behaviors and its association with substance use and mental health problems among adolescents in treatment. A pooled dataset of 9,519 adolescents admitted to substance abuse treatment programs between 2002 and 2006 was analyzed. HIV risk behaviors, substance use, and mental health problems were assessed at treatment intake. Sixty percent of adolescents were engaged in at least one sexual or needle use risk behavior in the year prior to entering treatment. Sex with multiple partners, sex under the influence of alcohol or drugs, and unprotected sex were the most prevalent HIV risk behaviors. Several gender differences were found for specific types of sexual and needle use behaviors. Adolescents with substance dependence or other comorbid mental health problems were at increased odds for HIV risk. Findings suggest treatment programs may benefit adolescents better by screening them consistently for HIV risk behaviors and incorporating tailored interventions.

    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.

    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.

    Full Text Available HIV diagnostic testing has come a long way since its inception in the early 1980s. Current enzyme immunoassays are sensitive enough to detect antibody as early as one to two weeks after infection. A variety of other assays are essential to confirm positive antibody screens (Western blot, polymerase chain reaction [PCR], provide an adjunct to antibody testing (p24 antigen, PCR, or provide additional information for the clinician treating HIV-positive patients (qualitative and quantitative PCR, and genotyping. Most diagnostic laboratories have complex testing algorithms to ensure accuracy of results and optimal use of laboratory resources. The choice of assays is guided by the initial screening results and the clinical information provided by the physician; both are integral to the laboratory's ability to provide an accurate laboratory diagnosis. Laboratories should also provide specific information on specimen collection, storage and transport so that specimen integrity is not compromised, thereby preserving the accuracy of laboratory results. Point of Care tests have become increasingly popular in the United States and some places in Canada over the past several years. These tests provide rapid, on-site HIV results in a format that is relatively easy for clinic staff to perform. However, the performance of these tests requires adherence to good laboratory quality control practices, as well as the backup of a licensed diagnostic laboratory to provide confirmation and resolution of positive or indeterminate results. Laboratory quality assurance programs and the participation in HIV proficiency testing programs are essential to ensure that diagnostic laboratories provide accurate, timely and clinically relevant laboratory results.

  11. Hepatitis Infection in the Treatment of Opioid Dependence and Abuse

    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

  12. Drug-induced reactivation of apoptosis abrogates HIV-1 infection.

    Directory of Open Access Journals (Sweden)

    Full Text Available HIV-1 blocks apoptosis, programmed cell death, an innate defense of cells against viral invasion. However, apoptosis can be selectively reactivated in HIV-infected cells by chemical agents that interfere with HIV-1 gene expression. We studied two globally used medicines, the topical antifungal ciclopirox and the iron chelator deferiprone, for their effect on apoptosis in HIV-infected H9 cells and in peripheral blood mononuclear cells infected with clinical HIV-1 isolates. Both medicines activated apoptosis preferentially in HIV-infected cells, suggesting that the drugs mediate escape from the viral suppression of defensive apoptosis. In infected H9 cells, ciclopirox and deferiprone enhanced mitochondrial membrane depolarization, initiating the intrinsic pathway of apoptosis to execution, as evidenced by caspase-3 activation, poly(ADP-ribose polymerase proteolysis, DNA degradation, and apoptotic cell morphology. In isolate-infected peripheral blood mononuclear cells, ciclopirox collapsed HIV-1 production to the limit of viral protein and RNA detection. Despite prolonged monotherapy, ciclopirox did not elicit breakthrough. No viral re-emergence was observed even 12 weeks after drug cessation, suggesting elimination of the proviral reservoir. Tests in mice predictive for cytotoxicity to human epithelia did not detect tissue damage or activation of apoptosis at a ciclopirox concentration that exceeded by orders of magnitude the concentration causing death of infected cells. We infer that ciclopirox and deferiprone act via therapeutic reclamation of apoptotic proficiency (TRAP in HIV-infected cells and trigger their preferential elimination. Perturbations in viral protein expression suggest that the antiretroviral activity of both drugs stems from their ability to inhibit hydroxylation of cellular proteins essential for apoptosis and for viral infection, exemplified by eIF5A. Our findings identify ciclopirox and deferiprone as prototypes of

    An accurate and rapid serologic method to differentiate HIV-2 from HIV-1 infection is required since the confirmatory HIV-1 Western Blot (WB) may demonstrate cross-reactivity with HIV-2 antibodies. To evaluate the performance of the Bio-Rad Multispot HIV-1/HIV-2 rapid assay as a supplemental test to correctly identify HIV-2 infection and identify HIV-1 WB cross-reactivity with HIV-2 in clinical samples tested at an academic medical center. Between August 2008 and July 2012, clinical samples were screened for HIV using either 3rd- or 4th-generation HIV-1/2 antibody or combination antibody and HIV-1 p24 antigen assays, respectively. All repeatedly reactive samples were reflexed for Multispot rapid testing. Multispot HIV-2 and HIV-1 and HIV-2-reactive samples were further tested using an HIV-2 immunoblot assay and HIV-1 or HIV-2 RNA assays when possible. The HIV-1 WB was performed routinely for additional confirmation and to assess for HIV-2 antibody cross-reactivity. Of 46,061 samples screened, 890 (89.6%) of 993 repeatedly reactive samples were also Multispot-reactive: 882 for HIV-1; three for only HIV-2; and five for both HIV-1 and HIV-2. All three HIV-2-only Multispot-positives along with a single dually reactive HIV-1/2 Multispot-positive were also HIV-2 immunoblot-positive; the latter was HIV-1 RNA negative and HIV-2 RNA positive. The Multispot rapid test performed well as a supplemental test for HIV-1/2 diagnostic testing. Four new HIV-2 infections (0.45%) were identified from among 890 Multispot-reactive tests. The use of HIV-1 WB alone to confirm HIV-1/2 screening assays may underestimate the true prevalence of HIV-2 infection in the United States. Copyright © 2013 Elsevier B.V. All rights reserved.

    We determined the impact of three factors on mortality in HIV-infected patients who had been on highly active antiretroviral therapy (HAART) for at least one year: (1) insufficient response to (HAART) and presence of AIDS-defining diseases, (2) comorbidity, and (3) drug and alcohol abuse and compared the mortality to that of the general population. In a Danish nationwide, population-based cohort study, we used population based registries to identify (1) all Danish HIV-infected patients who started HAART in the period 1 January 1998-1 July 2009, and (2) a comparison cohort of individuals matched on date of birth and gender (N = 2,267 and 9,068, respectively). Study inclusion began 1 year after start of HAART. Patients were categorised hierarchically in four groups according to the three risk factors, which were identified before study inclusion. The main outcome measure was probability of survival from age 25 to 65 years. The probability of survival from age 25 to age 65 was substantially lower in HIV patients [0.48 (95% confidence interval (CI) 0.42-0.55)] compared to the comparison cohort [0.88 (0.86 to 0.90)]. However, in HIV patients with no risk factors (N = 871) the probability of survival was equivalent to that of the general population [0.86 (95% CI 0.77-0.92)]. In contrast, the probability of survival was 0.58 in patients with HIV risk factors (N = 704), 0.30 in patients with comorbidities (N = 479), and 0.03 in patients with drug or alcohol abuse (N = 313). The increased risk of death in HIV-infected individuals is mainly attributable to risk factors that can be identified prior to or in the initial period of antiretroviral treatment. Mortality in patients without risk factors on a successful HAART is almost identical to that of the non-HIV-infected population.

    Failure of antiretroviral therapy to eradicate HIV, even in individuals who suppress the virus to undetectable levels, is a consequence of persistent infection in latently infected cells and within anatomical reservoirs. Support for the notion that the lungs are distinct anatomical reservoirs of HIV comes from a spectrum of studies that have documented different levels of HIV within the lungs compared with the peripheral blood. Different HIV variants have also been found within these two compartments, including variants with distinct antiretroviral resistance mutations. Given that macrophages are long-lived cellular reservoirs of HIV because of their resistance to apoptosis, HIV can persist for prolonged periods within alveolar macrophages that are abundant within the lungs. Furthermore, the large number of cells in close proximity within the lungs provides fertile grounds for cell-to-cell spread of HIV. Distinct immunological pressures in the lungs compared with the peripheral blood likely account for differences in HIV levels within these two compartments in addition to the finding of different variants within these regions. Furthermore, coinfections and tobacco may serve as local stimuli to induce further HIV replication within the lungs. Herein, we review the evidence supporting the notion that lungs are important reservoirs of HIV infection, and we discuss various factors influencing HIV burden within these reservoirs.

    The risk factors for acquiring Helicobacter pylori and Human Immunodeficiency Virus (HIV) infections are different: H. pylori is transmitted by gastro- or fecal-oral routes and is associated with low socioeconomic conditions, while HIV is transmitted through sexual intercourse, infected body fluids, and transplacentally. If the host responses to these infections were independent, the prevalence of H. pylori should be similar in HIV-infected and non-infected patients. Yet, several studies have detected a lower prevalence of H. pylori in patients with HIV infection, whereas other studies found either no differences or greater rates of H. pylori infection in HIV-positive subjects. To review studies that addressed the issue of these two simultaneous infections and attempt to determine whether reliable conclusions can be drawn from this corpus of often contrasting evidence. Electronic literature search for relevant publications, followed by manual search of additional citations from extracted articles. The initial search yielded 44 publications; after excluding case reports, reviews, narrowly focused articles, and duplicate reports, there remained 29 articles, which are the corpus of this review. With one exception, all studies reported higher rates of H. pylori infection in HIV-negative subjects. Five studies also examined the CD4 lymphocyte counts and found an inverse correlation between the degree of immunosuppression and the prevalence of active H. pylori infection. Current evidence suggests that it is likely that H. pylori needs a functional immune system to successfully and persistently colonize the human gastric mucosa. © 2014 John Wiley & Sons Ltd.

    Modern antiretroviral treatment belongs to the greatest success of current medicine. HIV infection has gone from a death sentence to a manageable chronic disease which develops several decades. Thanks to treatment advances, people with HIV can and do live long and full lives. In the last two decades, the incidence AIDS defining illnesses have been dramatically reduced especially opportunistic infections and malignancies, whereas the role of non-infection comorbidities has risen than age-matched HIV uninfected adults. These comorbidities include cardiovascular diseases, venous and arterial thrombosis, metabolic disorders, chronic liver and renal diseases, nervous system disorders, osteoporosis and some cancers. This relatively large group of diseases is known as non-AIDS defining or indicating diseases and these diseases are associated in HIV uninfected general population with older age and ageing Most HIV positive individuals on antiretrovirals present an abnormal level of immune activation, inflammation and hypercoagulable condition. These hallmarks are typically seen in older HIV uninfected general population and are associated with aging and the immunosenescent phenotype. The explanation for this phenomenon is unclear. There are multiple factors, which may apply pathophysiologically, including the residual immune dysregulation syndrome and antiretrovirals alone. It is clear that changes in the nature of chronic HIV infection put it in internal medicine. Cardiology, internal medicine, geriatric and oncology syndromes are dominating manifestations in HIV positive patients on antiretrovirals. Care management for HIV infected individuals will need to draw on a wide range of medical disciplines in diagnosis and treatment. Clarification of these phenomena would be beneficial for the treatment of these non-infectious diseases in HIV positive and as well in HIV negative general population.Key words: antiretroviral therapy - HIV infection - immune dysregulation

    Full Text Available Abstract Background One of the major health problems among HIV seropositive patients is superimposed infection due to the defect of immunity. Furthermore, intestinal parasite infection, which is also one of the basic health problems in tropical region, is common in these patients. In this study, a cross sectional study to document the prevalence of intestinal parasitic infection in Thai HIV-infected patients with different immune status was performed. Methods A study of stool samples from 60 Thai HIV-infected patients with different immune status was performed at King Chulalongkorn Memorial Hospital, Thailand. Each patient was examined for CD4 count and screened for diarrheal symptoms. Results The prevalence of intestinal parasitic infection among the HIV-infected patients in this study was 50 %. Non- opportunistic intestinal parasite infections such as hookworms, Opisthorchis viverrini and Ascaris lumbricoides were commonly found in HIV-infected people regardless of immune status with or without diarrheal symptoms. Opportunistic intestinal parasites such as Cryptosporidium, Isospora belli, Microsporidia and Strongyloides stercoralis infection were significantly more frequent in the low immunity group with diarrhea. Conclusion Therefore, opportunistic intestinal parasite infection should be suspected in any HIV infected patient with advanced disease presenting with diarrhea. The importance of tropical epidemic non-opportunistic intestinal parasite infections among HIV-infected patients should not be neglected.

    Full Text Available Background. Compliance with medication requires good sense of smell and taste. Objective. To evaluate the olfactory and gustatory function of HIV infected women in Ibadan, Nigeria. Methods. A case control study of women comprising 83 HIV infected women and 79 HIV uninfected women. Subjective self-rating of taste and smell function was by visual analogue scale. Olfactory function was measured via olfactory threshold (OT, olfactory discrimination (OD, olfactory identification (OI, and TDI using “Sniffin’ sticks” kits and taste function (Total Taste Strips (TTS score measurement was by taste strips. Results. The mean age of the HIV infected women was 43.67 years ± 10.72 and control was 41.48 years ± 10.99. There was no significant difference in the self-reported assessment of smell (p=0.67 and taste (p=0.84 of HIV infected and uninfected women. Although the mean OT, OD, OI, TDI, and TTS scores of HIV infected and uninfected women were within the normosmic and normogeusic values, the values were significantly higher in the controls (p<0.05. Hyposmia was in 39.7% of subjects and 12.6% of controls while hypogeusia was in 15.7% of subjects and 1.3% of controls. Conclusions. Hyposmia and hypogeusia are commoner among the HIV infected women than the HIV uninfected women and the risk increases with an increased duration of highly active antiretroviral therapy.

  5. Faces of Frailty in Aging with HIV Infection.

    Thurn, Marion; Gustafson, Deborah R

    2017-02-01

    The number of adults who are aging successfully and have HIV infection is increasing. More effective antiretroviral therapy (ART) regimens are preventing individuals infected with HIV from reaching end stages of the HIV infection and developing AIDS (acquired immunodeficiency syndrome). However, even at lower viral loads, chronic HIV infection appears to have consequences on aging processes, including the development of frailty. Frailty is a term used to describe vulnerability in aging. Frailty indices such as the Fried Frailty Index (FFI), the Veterans Aging Cohort Study (VACS) Index, and the Center for Epidemiologic Studies Depression scale (CES-D), an index of emotional frailty, associate with or predict clinical outcomes and death. However, even among existing frailty definitions, components require rigorous and consistent standardization. In the Women's Interagency HIV Study (WIHS), we have shown that frailty does not exist in isolation, even in midlife, and we use frailty to predict death. Frailty indices should be systematically used by health professionals to evaluate health and future risks for adverse events. Frailty prevention efforts, especially among those with HIV infection, appear to be essential for "successful aging" or aging without disability or loss of independence and may prevent HIV transmission. Taking care of elderly people is one of the major challenges of this century, and we must expect and be prepared for an increase in the number of aging adults, some of whom are patients with many co-morbidities and HIV infection.

    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.

    Full Text Available Gabriel Somarriba, Daniela Neri, Natasha Schaefer, Tracie L MillerDivision of Pediatric Clinical Research, Department of Pediatrics, Miller School of Medicine, University of Miami, Miami, Florida, USAAbstract: Medical advances continue to change the face of human immunodeficiency virus–acquired immunodeficiency syndrome (HIV/AIDS. As life expectancy increases, the number of people living with HIV rises, presenting new challenges for the management of a chronic condition. Aging, nutrition, and physical activity can influence outcomes in other chronic conditions, and emerging data show that each of these factors can impact viral replication and the immune system in HIV. HIV infection results in a decline of the immune system through the depletion of CD4+ T cells. From initial infection, viral replication is a continuous phenomenon. Immunosenescence, a hallmark of aging, results in an increased susceptibility to infections secondary to a delayed immune response, and this phenomenon may be increased in HIV-infected patients. Optimal nutrition is an important adjunct in the clinical care of patients with HIV. Nutritional interventions may improve the quality and span of life and symptom management, support the effectiveness of medications, and improve the patient’s resistance to infections and other disease complications by altering immunity. Moderate physical activity can improve many immune parameters, reduce the risk of acute infection, and combat metabolic abnormalities. As people with HIV age, alternative therapies such as nutrition and physical activity may complement medical management.Keywords: HIV replication, aging, diet, nutrition, exercise, immunity

    Outbreaks of HIV infection have been linked to injectable drug abuse, but specific triggers often remain obscure. We report on an outbreak of primary HIV infection among people who inject drugs (PWID) in Tel Aviv, associated with a local shift in drug-use practices. A cluster of primary HIV infection cases in PWID was detected in May 2012. Retrospective and prospective multi-hospital case finding was initiated. PWID were interviewed and risk factors for primary HIV infection were identified. Starting in December 2012, a multifaceted intervention was implemented, including educational activities, increasing syringe exchange supplies, active screening, early initiation of antiretroviral therapy, and referral to drug withdrawal programmes. Forty-two PWID with primary HIV infection were detected between May 2012 and April 2013. Compared with the corresponding pre-outbreak period, the annual incidence of primary HIV infection in PWID increased from 0 to 20 cases/1000 population (p infections and sepsis. Phylogenetic analysis of HIV isolates from case patients showed tight clustering suggesting a single common source of infection. The outbreak was temporally related to a widespread shift from heroin to injectable cathinone-derivatives and buprenorphine, which entailed high-risk injection practices. Targeted intervention resulted in a dramatic and sustained reduction in HIV infection in the PWID population. Injectable amphetamines are gaining momentum among PWID worldwide. Tracing of this outbreak to cathinone use and implementing a targeted intervention programme effectively terminated the outbreak.

    2012-06-01

    Full Text Available Background & Objective: The immune system of Patients with Acquired Immune Deficiency Syndrome (AIDS is weekend because of Human immunodeficiency virus (HIV infection, and they become vulnerable to several opportunistic and non-opportunistic pathogens and different carcinomas. 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.

    We compared the serologic response to HIV infection in Ugandan women with HIV subtype A (N=82) and D (N=32) infection using a limiting antigen avidity assay (LAg-Avidity assay); 2,614 samples were analyzed. Study participants were followed a median of 6.6 years after HIV seroconversion. Samples were classified as assay positive if they had a LAg-Avidity assay result infection were more likely to have delayed antibody maturation. During the first 2 years after seroconversion, the mean time that women had an assay-positive result (mean duration of recent infection, MDRI) was longer for women with subtype D infection than women with subtype A infection (267.9 days, 95% CI: 231.2-308.2 vs. 167.3 days, 95% CI: 151.8-185.9 days, pinfection after excluding low viral load samples and samples from women on antiretroviral therapy (ART). Women infected for >2 years were also more likely to be misclassified as recently infected in they had subtype D infection. Women with subtype D infection were also more likely to have antibody waning compared to women with subtype A infection. These findings may be related to the higher pathogenicity of subtype D HIV infection and are relevant to use of the LAg-Avidity assay for cross-sectional HIV incidence estimation in populations where subtype D infection is prevalent.

We have used a magnetic cell sorting (MACS) system to enrich CD4 cells. Using positive selection, CD4 cells...... expression and no loss of polyclonality. Only in two of six cultures were we able to detect HIV-antigen production, and using an LTR-PCR and an RT assay, we did not find activation of the HIV infection during the culture period. Thus, the method described separates and expands CD4 cells from HIV......-positive patients without activation of the HIV infection....

    Full Text Available BACKGROUND: Knowledge of the number of recent HIV infections is important for epidemiologic surveillance. Over the past decade approaches have been developed to estimate this number by testing HIV-seropositive specimens with assays that discriminate the lower concentration and avidity of HIV antibodies in early infection. We have investigated whether this "recency" information can also be gained from an HIV confirmatory assay. METHODS AND FINDINGS: The ability of a line immunoassay (INNO-LIA HIV I/II Score, Innogenetics to distinguish recent from older HIV-1 infection was evaluated in comparison with the Calypte HIV-1 BED Incidence enzyme immunoassay (BED-EIA. Both tests were conducted prospectively in all HIV infections newly diagnosed in Switzerland from July 2005 to June 2006. Clinical and laboratory information indicative of recent or older infection was obtained from physicians at the time of HIV diagnosis and used as the reference standard. BED-EIA and various recency algorithms utilizing the antibody reaction to INNO-LIA's five HIV-1 antigen bands were evaluated by logistic regression analysis. A total of 765 HIV-1 infections, 748 (97.8% with complete test results, were newly diagnosed during the study. A negative or indeterminate HIV antibody assay at diagnosis, symptoms of primary HIV infection, or a negative HIV test during the past 12 mo classified 195 infections (26.1% as recent (< or = 12 mo. Symptoms of CDC stages B or C classified 161 infections as older (21.5%, and 392 patients with no symptoms remained unclassified. BED-EIA ruled 65% of the 195 recent infections as recent and 80% of the 161 older infections as older. Two INNO-LIA algorithms showed 50% and 40% sensitivity combined with 95% and 99% specificity, respectively. Estimation of recent infection in the entire study population, based on actual results of the three tests and adjusted for a test's sensitivity and specificity, yielded 37% for BED-EIA compared to 35% and 33

    Little is known about the differences in clinical manifestations between women with various HIV-1 subtypes during acute (AI) and early (EI) HIV infection. In a longitudinal cohort study, clinical signs and symptoms among Uganda and Zimbabwe women with AI and EI were compared with HIV-negative controls; symptoms were assessed quarterly for 15 to 24 months. Early HIV infection was defined as the first visit during which a woman tested HIV antibody positive. Women who were HIV negative serologic...

    Intimate partner violence (IPV) has been associated with greater vulnerability to HIV infection among women. We examined prevalence and correlates of IPV among female sex workers (FSWs) in Tijuana and Ciudad Juarez, two large Mexico-U.S. border cities where HIV prevalence is rising. Participants were 300 FSWs with a current spouse or a steady partner. Participants' mean age was 33 years, and mean number of years as a sex worker was 6 years. The prevalence of IPV in the past 6 months among participants was 35%. Using multivariate logistic regression, factors independently associated with IPV included having experienced abuse as a child, a partner who had sex with someone else, and lower sexual relationship power. Our findings suggest the need for previous abuse screening and violence prevention services for FSWs in the Mexico-U.S. border region. Careful consideration of relationship dynamics such as infidelity and relationship power is warranted when assessing for IPV risk.

    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.

    This review aims to summarize recent developments in the epidemiology and management of sexually transmitted infections in HIV positive individuals. It will also discuss briefly the legal aspects of disclosure in relation to HIV transmission. There has been a dramatic increase in the reported number of cases of syphilis globally in recent years. In the United Kingdom this has mainly been observed among HIV positive men who have sex with men (MSM). Since 2003 there have been a series of outbreaks of lymphogranuloma venereum reported in several European cities occurring mostly in HIV positive MSM. Sexual transmission of hepatitis C is increasing and appears to be more common in HIV positive MSM. Legal issues regarding HIV transmission have also come to the fore, becoming an important part of the discussion of sexual health with an HIV positive patient. Increases in sexually transmitted infection among HIV positive individuals suggest a worrying lack of adherence to safe sex guidelines and needs to be addressed urgently. The transmission of HIV is facilitated by the presence of certain sexually transmitted infections. Management of sexual health is an essential part of HIV care.

    Prior studies have found that partner abuse is related to risky sexual behavior. However, few studies have explored gender, sexual orientation, or substance use differences in this association, especially among people with HIV. We examined data from the Risk and Prevention survey from the HIV Cost and Services Utilization Study (HCSUS) sample on 726 sexually-active individuals in three gender/orientation groups (286 women, 148 heterosexual men, and 292 gay/bisexual men). The study assessed whether individuals with HIV who experienced or perpetrated abuse within a close relationship were likely to engage in unprotected intercourse with that same partner. Both abuse perpetration and victimization were significantly associated with having any unprotected intercourse. In multivariate tests, gender/orientation and substance use during sex moderated the perpetration effects. Secondary HIV prevention interventions need to take into account potentially abusive contexts in which sexual activity may occur for both men and women.

    Integrating HIV prevention into substance abuse counselling is recommended to ameliorate the health outcomes of men who have sex with men. However, culture-based countertransferences (CBCs) may hamper this effort. Using a case illustration, this paper will explain the manifestation of CBCs held among substance abuse counsellors and how they hinder counsellors' work with men who have sex with men. The following CBCs will be explored: distancing, topic avoidance, heteronormativity, assumptions and denying client strengths. These CBCs allow counsellors to avoid discussions about sexual practices and curtail HIV prevention counselling, while undermining the counsellor-client relationship. Based on the empirical literature on HIV and substance abuse prevention with men who have sex with men, we provide recommendations to help counsellors overcome CBCs and integrate HIV prevention consistently with men who are in treatment for substance abuse.

    Attendees presenting for treatment of acute illness at primary health care facilities in South Africa were assessed to determine the prevalence of human immunodeficiency virus (HIV) infection and the predictability of group I oral lesions (GOLs) for HIV infection. This was a cross-sectional analytical study. Patients >18 years of age were recruited and underwent an oral examination and a HIV test. A total of 522 attendees were examined and the HIV prevalence was 40%. None of them were taking antiretroviral drugs. GOLs were diagnosed in 53% of HIV patients, with pseudomembranous and erythematous candidiasis being the most common (38% and 24%, respectively). The average odds and likelihood ratios for multiple lesions were high (32 and 30, respectively) and showed a strong correlation between GOLs and a positive HIV status. The prevalence of HIV (40%) and GOLs (53%) was high. GOLs were useful markers of HIV infection, with multiple lesions being highly predictive of HIV infection. Copyright (c) 2010 Mosby, Inc.

    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.

    Full Text Available Urogenital schistosomiasis, caused by infection with Schistosoma haematobium, is widespread and causes substantial morbidity on the African continent. The infection has been suggested as an unrecognized risk factor for incident HIV infection. Current guidelines recommend preventive chemotherapy, using praziquantel as a public health tool, to avert morbidity due to schistosomiasis. In individuals of reproductive age, urogenital schistosomiasis remains highly prevalent and, likely, underdiagnosed. This comprehensive literature review was undertaken to examine the evidence for a cause-effect relationship between urogenital schistosomiasis and HIV/AIDS. The review aims to support discussions of urogenital schistosomiasis as a neglected yet urgent public health challenge.We conducted a systematic search of the literature including online databases, clinical guidelines, and current medical textbooks. We describe plausible local and systemic mechanisms by which Schistosoma haematobium infection could increase the risk of HIV acquisition in both women and men. We also detail the effects of S. haematobium infection on the progression and transmissibility of HIV in co-infected individuals. We briefly summarize available evidence on the immunomodulatory effects of chronic schistosomiasis and the implications this might have for populations at high risk of both schistosomiasis and HIV.Studies support the hypothesis that urogenital schistosomiasis in women and men constitutes a significant risk factor for HIV acquisition due both to local genital tract and global immunological effects. In those who become HIV-infected, schistosomal co-infection may accelerate HIV disease progression and facilitate viral transmission to sexual partners. Establishing effective prevention strategies using praziquantel, including better definition of treatment age, duration, and frequency of treatment for urogenital schistosomiasis, is an important public health priority.

    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.

    Disease progression is rapid in human immunodeficiency virus (HIV)-infected infants. Whether intestinal damage and inflammation underlie mortality is unknown. We measured plasma intestinal fatty acid binding protein (I-FABP), soluble CD14 (sCD14), interleukin 6 (IL-6), and C-reactive protein (CRP) at 6 weeks and 6 months of age in 272 HIV-infected infants who either died (cases) or survived (controls), and in 194 HIV-exposed uninfected (HEU) and 197 HIV-unexposed infants. We estimated multivariable odds ratios for mortality and postnatal HIV transmission for each biomarker using logistic regression. At 6 weeks, HIV-infected infants had higher sCD14 and IL-6 but lower I-FABP than HIV-exposed and HIV-unexposed infants (P HIV-exposed than HIV-unexposed infants (P = .02). At 6 months, HIV-infected infants had highest sCD14, IL-6, and CRP concentrations (P HIV-exposed vs HIV-unexposed infants (P = .04). No biomarker was associated with mortality in HIV-infected infants, or with odds of breast-milk HIV transmission in HIV-exposed infants. HIV-infected infants have elevated inflammatory markers by 6 weeks of age, which increase over time. In contrast to adults and older children, inflammatory biomarkers were not associated with mortality. HEU infants have higher inflammation than HIV-unexposed infants until at least 6 months, which may contribute to poor health outcomes.

  12. Sex and gender differences in HIV-1 infection.

    2016-08-01

    The major burden of the human immunodeficiency (HIV) type 1 pandemic is nowadays carried by women from sub-Saharan Africa. Differences in the manifestations of HIV-1 infection between women and men have been long reported, and might be due to both socio-economic (gender) and biological (sex) factors. Several studies have shown that women are more susceptible to HIV-1 acquisition than men. Following HIV-1 infection, women have lower viral loads during acute infection and exhibit stronger antiviral responses than men, which may contribute to differences in the size of viral reservoirs. Oestrogen receptor signalling could represent an important mediator of sex differences in HIV-1 reservoir size and may represent a potential therapeutic target. Furthermore, immune activation, a hallmark of HIV-1 infection, is generally higher in women than in men and could be a central mechanism in the sex difference observed in the speed of HIV-1 disease progression. Here, we review the literature regarding sex-based differences in HIV-1 infection and discuss how a better understanding of the underlying mechanisms could improve preventive and therapeutic strategies. © 2016 The Author(s). published by Portland Press Limited on behalf of the Biochemical Society.

    The prognosis of human immunodeficiency virus (HIV) infection has improved in recent years with the introduction of antiretroviral treatment. While the frequency of AIDS-defining events has decreased as a cause of death, mortality from non-AIDS-related events including end-stage renal diseases has increased. The etiology of chronic kidney disease is multifactorial: immune-mediated glomerulonephritis, HIV-associated nephropathy, thrombotic microangiopathies, and so on. HIV infection is no longer a contraindication to transplantation and is becoming standard therapy in most developed countries. The HIV criteria used to select patients for renal transplantation are similar in Europe and North America. Current criteria state that prior opportunistic infections are not a strict exclusion criterion, but patients must have a CD4+ count above 200 cells/mm(3) and a HIV-1 RNA viral load suppressible with treatment. In recent years, more than 200 renal transplants have been performed in HIV-infected patients worldwide, and mid-term patient and graft survival rates have been similar to that of HIV-negative patients. The main issues in post-transplant period are pharmacokinetic interactions between antiretrovirals and immunosuppressants, a high rate of acute rejection, the management of hepatitis C virus coinfection, and the high cardiovascular risk after transplantation. More studies are needed to determine the most appropriate antiretroviral and immunosuppressive regimens and the long-term outcome of HIV infection and kidney graft. © 2011 International Society of Nephrology

  14. Prevalence of HIV infection among tuberculosis patients in Eastern India.

    India has a high tuberculosis (TB) burden. A significant percentage of TB patients are human immunodeficiency virus (HIV) positive. As the HIV epidemic is fueling the global TB epidemic, the prevalence of the virus in TB patients is a sensitive indicator of the spread of HIV into the general population in many regions. The aim of this study was to determine the prevalence of HIV-TB co-infection among a less studied population of Eastern India. A cross-sectional record analysis study covering the period from 2000 to 2011 was conducted at Central Hospital of South Eastern Railway, Garden Reach, Kolkata, India. All tuberculosis patients consenting for HIV testing were included in the study after obtaining ethical clearance from the institution. The TB diagnosis was performed using clinical examination, sputum acid-fast bacillus (AFB) smear and chest radiography. HIV-positive cases were screened using an initial HIV tridot test, followed by repetitive tests using a Micro ELISA HIV Kit for HIV 1 and HIV 2 antigen. Overall, 50 (12.3%) of the consenting 406 TB patients were HIV positive. Of these 406 patients, 44% had pulmonary TB, and 56% had extrapulmonary TB (EPTB). Coughing was the most common symptom (90%), followed by fever (78%). Pleural effusion (60.7%) was the most common form observed in the EPTB cases. The prevalence of HIV-TB co-infection was 12.3%. Consequently, all TB patients should be assessed for HIV risk factors and counseled to undergo HIV testing. Conversely, all HIV-positive cases should be screened for TB.

    Because of the clinical difficulty in identifying the early stages of human immunodeficiency virus (HIV) infection, the histopathologist often has to consider the diagnosis of HIV in tissue samples from patients with no previous suspicion of HIV infection. The aim was to investigate the practicality and utility of routine HIV-1 p24 immunohistochemistry on tissue samples received at a London histopathology laboratory. Over a 3-year period, HIV-1 p24 was evaluated immunohistochemically on 123 cases. Of these, 37 (30%) showed positive expression of p24 in lesional follicular dendritic cells (FDCs). Of these 37 cases, 11 were not clinically suspected to be HIV+ and had no prior serological evidence of HIV infection. These cases represented lymph node biopsies, tonsillar and nasopharyngeal biopsies and a parotid excision. In addition to expression on FDCs, in 22 cases (60%), p24 also highlighted mononuclear cells and macrophages. p24 was also useful in confirming the presence of HIV in lymphoid tissue in non-lymphoid organs such as the lung, anus, salivary gland and brain. Immunonegativity occurred in occasional known HIV+ cases, probably related to treatment or tissue processing. This study confirms the usefulness of this technique in detecting unsuspected HIV infection in lymphoid and non-lymphoid organs on histopathological material and should be part of routine evaluation of lymph nodes and lymphoid tissue in other organs if morphological or clinical features suggest HIV infection.

    HIV infection is associated with an increased prevalence of common mental disorders and with the development of HIV associated neurological disorders (HAND). The aim of this research was to determine the reliability of lay adherence counsellors in the administration of the substance abuse and mental illness symptom screener (SAMISS) for common mental disorders and International HIV Dementia Scale (IHDS) for HAND in a South African sample of 269 people living with HIV/AIDS and on HAART in a primary healthcare setting. We used a cross-sectional design with each patient assessed by a mental health nurse and counsellor, 1 week apart. Reliability was fair for the SAMISS overall (κ = 0.39, CI(95) 0.29-0.49, P substance abuse component compared to the mental illness component. Reliability for the IHDS between counsellors and nurses was slight (κ = 0.11, CI(95) 0.00-0.27, P nurses for the both the SAMISS and IHDS. Strategies to improve the ability of primary healthcare providers to screen for neurocognitive disorders as well as avoiding over-detection of mental illness and substance abuse symptoms need to be developed and implemented for the primary healthcare setting.

    With the introduction of antiretroviral therapy (ART), a dramatic reduction in HIV-related morbidity and mortality has been observed. However, it is now becoming increasingly clear that liver-related complications, particularly rapid fibrosis development from ART as well as from the chronic HIV infection itself, are of serious concern to HIV patients. The pathophysiology of liver fibrosis in patients with HIV is a multifactorial process whereby persistent viral replication, and bacterial translocation lead to chronic immune activation and inflammation, which ART is unable to fully suppress, promoting production of fibrinogenic mediators and fibrosis. In addition, mitochondrial toxicity, triggered by both ART and HIV, contributes to intrahepatic damage, which is even more severe in patients co-infected with viral hepatitis. In recent years, new insights into the mechanisms of accelerated fibrosis and liver disease progression in HIV has been obtained, and these are detailed and discussed in this review.

  1. CTL Escape and Viral Fitness in HIV/SIV Infection.

    Cytotoxic T lymphocyte (CTL) responses exert a suppressive effect on HIV and simian immunodeficiency virus (SIV) replication. Under the CTL pressure, viral CTL escape mutations are frequently selected with viral fitness costs. Viruses with such CTL escape mutations often need additional viral genome mutations for recovery of viral fitness. Persistent HIV/SIV infection sometimes shows replacement of a CTL escape mutation with an alternative escape mutation toward higher viral fitness. Thus, multiple viral genome changes under CTL pressure are observed in the chronic phase of HIV/SIV infection. HIV/SIV transmission to HLA/MHC-mismatched hosts drives further viral genome changes including additional CTL escape mutations and reversions under different CTL pressure. Understanding of viral structure/function and host CTL responses would contribute to prediction of HIV evolution and control of HIV prevalence.

    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

    Full Text Available Reproductive tract infection (RTIs/sexually transmitted infections (STIs are recognized as a major public health problem, particularly due to their relationship with HIV infection. Early detection and treatment of Chlamydia trachomatis infection (CTI among HIV-infected and HIV-uninfected women may impact heterosexual HIV transmission. A total of 120 participants were enrolled: 30 HIV seropositive women with symptoms of RTIs, 30 HIV seropositive women without symptoms of RTIs, 30 HIV seronegative women with symptoms of RTIs, and 30 HIV seronegative women without symptoms of RTIs. One endocervical swab was collected from all participants and CTI was detected by real-time PCR (COBAS TaqMan CT Test, v2.0. CTI was detected in 4 (6.67% HIV-infected women and in 1 (1.67% HIV-uninfected woman (OR 4.214; 95% CI 0.457–38.865. Vaginal discharge was present in almost half of HIV-infected and HIV-uninfected women; lower abdominal pain was present in 11 (18.3% of HIV-infected and in 9 (15% of HIV-uninfected women. This study showed that CTI is more prevalent among HIV-infected females as compared to HIV-uninfected females. As the use of real-time PCR is not feasible in most hospitals, efforts should be made to develop a simple, sensitive, and specific test to identify women with CTI for prevention of sequelae and HIV transmission.

    This study examined gender differences in the rates and correlates of HIV risk behaviors among 1,429 clients participating in multi-site trials throughout the United States between 2001 and 2005 as part of the National Institute on Drug Abuse-funded Clinical Trials Network. Women engaged in higher risk sexual behaviors. Greater alcohol use and psychiatric severity were associated with higher risk behaviors for women, while impaired social relations were associated with decreased risk for men. Specific risk factors were differentially predictive of HIV risk behaviors for women and men, highlighting the need for gender-specific risk-reduction interventions. Limitations of the study are discussed. PMID:20536356

    To describe and correlate placental characteristics from pregnancies in HIV-infected and HIV-negative women with maternal and infant clinical and immunological data. Prospective descriptive study of placentas from term, uncomplicated vaginal births in a cohort of HIV-infected (n = 120) and HIV-negative (n = 103) women in Cape Town, South Africa. Microscopic and macroscopic features were used to determine pathological cluster diagnoses. The majority of HIV-infected women received some form of drug treatment for the prevention of vertical transmission of HIV. Data were analysed using logistic regression. HIV-infected women were older (median [IQR] 27.4 years [24-31] vs. 25.8 [23-30]), more likely to be multiparous (81.7% vs. 71.8%) and had lower CD4 counts (median [IQR] 323.5 cells/ml [235-442] vs. 467 [370-656]). There were no differences in gestational age at first antenatal visit or at delivery. The proportion of specimens with placental lesions was similar in both groups (39.2% vs. 44.7%). Half of all samples were below the tenth percentile expected-weight-for-gestation regardless of HIV status. This was unaffected by adjustment for confounding variables. Maternal vascular malperfusion (MVM) was more frequent in HIV infection (24.2% vs. 12.6%; P = 0.028), an association which strengthened after adjustment (aOR 2.90 [95% confidence interval 1.11-7.57]). Otherwise the frequency of individual diagnoses did not differ between the groups on multivariate analysis. In this cohort of term, uncomplicated pregnant women, few differences were observed between the HIV-infected and uninfected groups apart from MVM. This lesion may underlie the development of hypertensive disorders of pregnancy, which have been observed at higher rates in some HIV-infected women on ART. © 2017 John Wiley & Sons Ltd.

  10. Latent and Active Tuberculosis Infection Increase Immune Activation in Individuals Co-Infected with HIV

    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.

    Full Text Available 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.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.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.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.

    Vaccination is the most important preventive strategy against influenza, however post-vaccination antibody responses are often inadequate especially among HIV-infected persons. Vitamin D deficiency has been suggested to adversely influence immune responses and is highly prevalent among HIV-infected adults. Therefore, we evaluated the association between 25-hydroxyvitamin D [25(OH)D] levels and post-influenza vaccination responses. We conducted a prospective cohort study evaluating the immunogenicity of monovalent influenza A (H1N1) vaccination among both HIV-infected and HIV-uninfected adults (18-50years of age) during the 2009-2010 influenza season. Antibody titers were evaluated at baseline, day 28, and 6months post-vaccination using hemagluttination inhibition assays. Serum 25(OH)D levels were measured at day 28. Univariate and multivariate regression analyses examined the association between 25(OH)D levels [categorized as <20ng/ml (deficiency) vs. ⩾20ng/ml] with the primary outcome of seroconversion. Secondary outcomes included seroprotection; a ⩾4-fold increase in titers; and geometric mean titers post-vaccination. Analyses were repeated using 25(OH)D levels as a continuous variable. A total of 128 adults [64 HIV-infected (median CD4 count 580cells/mm(3)) and 64 HIV-uninfected] were included. Seroconversion at day 28 post-vaccination was achieved in fewer HIV-infected participants compared with HIV-uninfected participants (56% vs. 74%, p=0.03). Vitamin D deficiency was more prevalent among HIV-infected persons vs. HIV-uninfected persons (25% vs. 17%), although not significantly different (p=0.39). There were no associations found between lower 25(OH)D levels and poorer antibody responses at day 28 or 6months for any of the study outcomes among either HIV-infected or HIV-uninfected adults. Vitamin D deficiency was common among both HIV-infected and HIV-uninfected adults, but lower levels did not predict antibody responses after H1N1 (2009) influenza

    HIV/sexually transmitted infections (STIs) and drug abuse remain significant public health concerns in the United States, and African American and Hispanic youth are disproportionately affected. Although technology-based interventions are efficacious in preventing and reducing HIV/STI and licit/illicit drug use behaviors, relatively little is known regarding the state of the science of these interventions among African American and Hispanic youth. The aim of this review is to identify and examine randomized controlled trials (RCTs) of technology-based HIV/STI and/or drug abuse preventive interventions for African American and Hispanic youth. We searched electronic databases (ie, PubMed, Proquest, PsycINFO, Ebscohost, Google Scholar) to identify studies between January 2006 and October 2016. RCTs of technology-based interventions targeting African American and Hispanic youth HIV/STI risk behaviors, including sexual risk, licit and illicit drug use, and HIV/STI testing were included. Our search revealed a total of three studies that used an RCT design and included samples comprised of >50% African American and/or Hispanic youth. The follow-up assessments ranged from two weeks to six months and the number of participants in each trial ranged from 72 to 141. The three interventions were theory-driven, interactive, and tailored. The long-term effects of the interventions were mixed, and outcomes included reductions in sex partners, licit drug use, and condomless anal sex acts. Although technology-based interventions seem promising in the prevention of HIV/STI and drug abuse among African American and Hispanic youth, more research is needed.

    Angulo-Arreola, Iliana Alexandra; Bastos, Francisco I; Strathdee, Steffanie A

    The Caribbean and Central America represent a formidable challenge for researchers and policy makers in the HIV field, due to their pronounced heterogeneity in terms of social, economic, and cultural contexts and the different courses the HIV epidemic has followed in the region. Such contrasting contexts and epidemics can be exemplified by 2 countries that share the island of Hispaniola, the French Creole-speaking Haiti, and the Spanish-speaking Dominican Republic. Haiti has experienced the worst epidemics outside of sub-Saharan Africa. Following a protracted economic and social crisis, recently aggravated by a devastating earthquake, the local HIV epidemic could experience resurgence. The region, strategically located on the way between coca-producing countries and the profitable North American markets, has been a transshipment area for years. Notwithstanding, the impact of such routes on local drug scenes has been very heterogeneous and dynamic, depending on a combination of local mores, drug enforcement activities, and the broad social and political context. Injecting drug use remains rare in the region, but local drug scenes are dynamic under the influence of increasing mobility of people and goods to and from North and South America, growing tourism and commerce, and prostitution. The multiple impacts of the recent economic and social crisis, as well as the influence of drug-trafficking routes across the Caribbean and other Latin American countries require a sustained effort to track changes in the HIV risk environment to inform sound drug policies and initiatives to minimize drug-related harms in the region.

    Background We evaluated use of the ARCHITECT® HIV Ag/Ab Combo assay (HIV Combo; Abbott Diagnostics; available for sale outside of the U.S. only) for detection of acute HIV infection. Methods Samples were obtained from a behavioral intervention study (EXPLORE). HIV-uninfected men who have sex with men were enrolled and tested for HIV infection every 6 months. Samples from seroconverters collected at their last seronegative visit (n=217) were tested individually using two HIV RNA assays. Samples with detectable HIV RNA were classified as acute and were tested with HIV Combo. Samples from the enrollment visit (n=83) and the time of HIV seroconversion (n=219) were tested with HIV Combo as controls. Results Twenty-one (9.7%) samples from the last seronegative visit had detectable HIV RNA and were classified as acute. HIV Combo was positive for 13 (61.9%) of the acute samples. Samples not detected by HIV Combo had viral loads of 724 to 15,130 copies/ml. Expected results were obtained for positive and negative controls tested with HIV Combo. Conclusions HIV Combo detected nearly two-thirds of acute HIV infections identified in this high-risk population by non-pooled, HIV RNA assays. HIV Combo may be useful for high-throughput screening to identify individuals with acute HIV infection. PMID:19506484

    HIV-infected individuals are susceptible to development of chronic lung diseases, but little is known regarding the prevalence and risk factors associated with different spirometric abnormalities in this population. We sought to determine the prevalence, risk factors and performance characteristics of risk factors for spirometric abnormalities among HIV-infected individuals. Cross-sectional cohort study. We analyzed cross-sectional US data from the NHLBI-funded Lung-HIV consortium - a multicenter observational study of heterogeneous groups of HIV-infected participants in diverse geographic sites. Logistic regression analysis was performed to determine factors statistically significantly associated with spirometry patterns. A total of 908 HIV-infected individuals were included. The median age of the cohort was 50 years, 78% were men and 68% current smokers. An abnormal spirometry pattern was present in 37% of the cohort: 27% had obstructed and 10% had restricted spirometry patterns. Overall, age, smoking status and intensity, history of Pneumocystis infection, asthma diagnosis and presence of respiratory symptoms were independently associated with an abnormal spirometry pattern. Regardless of the presence of respiratory symptoms, five HIV-infected participants would need to be screened with spirometry to diagnose two individuals with any abnormal spirometry pattern. Nearly 40% of a diverse US cohort of HIV-infected individuals had an abnormal spirometry pattern. Specific characteristics including age, smoking status, respiratory infection history and respiratory symptoms can identify those at risk for abnormal spirometry. The high prevalence of abnormal spirometry and the poor predictive capability of respiratory symptoms to identify abnormal spirometry should prompt clinicians to consider screening spirometry in HIV-infected populations.

    2002-01-01

    To identify the incidence and correlates of physical and sexual violence among HIV-infected women at risk for pregnancy, a cross-sectional examination was conducted within a longitudinal study of reproductive decision making. Participants consisted of 275 HIV-infected women 17 to 49 years of age (mean = 30.1 years). Women were predominantly African American (87%) and single (82%), with annual incomes of $10,000 or less (66%). Overall, 68% of the women reported experiencing lifetime physical and/or sexual violence. Before becoming HIV infected, 65% of the women reported having been physically or sexually abused. After HIV diagnosis, 33% of the women reported experiencing physical or sexual abuse. Women reporting greater violence were more likely to disclose their HIV-seropositive status to their sex partner. Using logistic regression, greater intent to get pregnant (odds ratio [OR] = 0.933), decreased present life satisfaction (OR = 1.048), having three or more children (OR = 0.474), and history of drug use (OR = 0.794) significantly distinguished between women who reported physical and/or sexual violence and those who did not.

  7. CD8 T cell persistence in treated HIV infection

    2014-01-01

    Purpose of review Many treated HIV infected persons maintain persistently high circulating CD8 T cell numbers, even after many years of therapy. Recent reports suggest that persistent CD8 T cell expansion is associated with higher risk of morbid non-AIDS events. Thus, assessing the mechanisms of CD8 T cell expansion and persistence may give insights into a feature of HIV disease that is clinically important. Recent findings Acute HIV infection is associated with activation and expansion of the CD8 T cell compartment. Expanded CD8 T cells persist throughout disease course and, in contrast to the plasticity that typically characterizes immune responses to most other pathogens, circulating CD8 T cell numbers do not normalize in many patients despite pharmacological suppression of HIV replication. We suspect that residual inflammation in treated HIV infection contributes to antigen-independent CD8 T cell expansion and persistence as most of these cells are not HIV-reactive. Summary Circulating CD8 T cell numbers remain abnormally elevated in many treated HIV-infected patients and this elevation is associated with adverse clinical events. Future studies will need to assess the mechanisms of CD8 T cell expansion and to define the role of CD8 lymphocytosis in the clinical course of treated HIV disease. PMID:25010897

    2017-09-20

    South Africa has one of the highest HIV prevalences in the world, and compared with other sectors of the national economy, the construction industry is disproportionately adversely affected. Using data collected nationally from more than 57,000 construction workers, HIV infection among South African construction workers was estimated, together with an assessment of the association between worker HIV serostatus and worker characteristics of gender, age, nature of employment, occupation, and HIV testing history. The HIV infection of construction workers was estimated to be lower than that found in a smaller 2008 sample. All worker characteristics are significantly associated with HIV serostatus. In terms of most at-risk categories: females are more at risk of HIV infection than males; workers in the 30-49 year old age group are more at risk than other age groups; workers employed on a less permanent basis are more at risk; as are workers not having recently tested for HIV. Among occupations in the construction industry, general workers, artisans, and operator/drivers are those most at risk. Besides yielding more up-to-date estimated infection statistics, this research also identifies vulnerable sub-groups as valuable pointers for more targeted workplace interventions by construction firms.

    2018-01-01

    It is well-recognized that human immunodeficiency virus type-1 (HIV-1) mainly targets CD4+ T cells and macrophages. Nonetheless, during the past three decades, a huge number of studies have reported that HIV-1 can directly or indirectly target other cellular components of the immune system including CD8+ T cells, B cells, dendritic cells, natural killer cells, and polymorphonuclear neutrophils (PMNs), among others. PMNs are the most abundant leukocytes in the human circulation, and are known to play principal roles in the elimination of invading pathogens, regulating different immune responses, healing of injured tissues, and maintaining mucosal homeostasis. Until recently, little was known about the impact of HIV-1 infection on PMNs as well as the impact of PMNs on HIV-1 disease progression. This is because early studies focused on neutropenia and recurrent microbial infections, particularly, during advanced disease. However, recent studies have extended the investigation area to cover new aspects of the interactions between HIV-1 and PMNs. This review aims to summarize these advances and address the impact of HIV-1 infection on PMNs as well as the impact of PMNs on HIV-1 disease progression to better understand the pathophysiology of HIV-1 infection.

    Full Text Available Dermatophyte infections are common in HIV infected patients and can occur at some point during their illness. They may show clinical variations. The present study was to note the prevalence and clinical variations in dermatophytosis in HIV infected patients. Out of 185 HIV infected patients screened at our hospital, the diagnosis of dermatophytosis was made in 41 cases. The prevalence of dermatophytosis was 22.2% Male to female ratio was 3:1 The mean age of our patients was 30.7 years. The occupations of our patients in decreasing order of frequency were labourers (43.9%, drivers (29.3% and rest were housewives, commercial sex workers etc. Heterosexual route was the most common mode of acquisition of HIV infection. Tinea corporis was the commonest dermatophyte infection and was seen in 22 (53.7% cases, followed by tinea cruris in 18 (49.9%, tinea pedis in 7 (17.1, tinea faciei in 6 (14.7% and one patient had tinea manum infection. Tinea unguium was recorded in 11 cases. Out of the 22 patients with tinea corporis, 19 were in the HIV Group IV. Ten of them presented with multiple, large sharply marginated areas of hyperkeratosis resembling dry scaly skin (anergic form of tinea corporis. Proximal white subungual onychomycosis (PWSO, thought to be pathognomonic of HIV was seen in 3 cases only. This study has brought into focus variations in presentations of dermatophytosis.

  19. Predicting dentists' perceived occupational risk for HIV infection.

    Science.gov (United States)

    Kunzel, C; Sadowsky, D

    1993-06-01

    This study posed two questions: what is the level of perceived occupational risk among American general practice dentists (GPDs)? What factors influence perception of occupational risk for HIV infection among GPDs? In data obtained from a national mail survey of 1351 GPDs (response rate, 88%) 31% of American GPDs expressed disagreement with the statement that HIV+ individuals can be safely treated in their office settings. Of the 16 variables entered into a multiple regression equation, 9 variables had a statistically significant influence on dentists' assessment of occupational risk. In order of their influence they were (1) concern re the economic viability of the practice, (2) ethical obligation to treat patients at risk, (3) certainty of having treated patients with HIV infection, (4) risk attributed to four accidental occupational exposures, (5) concern re treatment of homosexuals, (6) relevant continuing education exposure, (7) personal worry re transmission of HIV infection from patients, (8) implementation of infection control behaviors, (9) number of patients seen per week. Statistically nonsignificant predictors of interest included age, knowledge level re HIV transmission routes, practice location in a high prevalence area, and perceived effectiveness of infection control behaviors. Results argue for intervention programs with less focus on delivery of factual information regarding the transmission of the disease and the effectiveness of infection control techniques, and more emphasis on the themes of practice economic viability, professional ethics, and structured educational encounters involving dentists' knowing exposure to HIV-infected patients.

    Objective This study examines the relationship between childhood abuse and neglect and sexual risk behavior in middle adulthood and whether psychosocial factors (risky romantic relationships, affective symptoms, drug and alcohol use, and delinquent and criminal behavior) mediate this relationship. Methods Children with documented cases of physical abuse, sexual abuse, and neglect (ages 0–11) processed during 1967–1971 were matched with non-maltreated children and followed into middle adulthood (approximate age 41). Mediators were assessed in young adulthood (approximate age 29) through in-person interviews between 1989 and 1995 and official arrest records through 1994 (N = 1,196). Past year HIV-risk sexual behavior was assessed via self-reports during 2003–2004 (N = 800). Logistic regression was used to examine differences in sexual risk behavior between the abuse and neglect and control groups, and latent variable structural equation modeling (SEM) was used to test mediator models. Results Child abuse and neglect was associated with increased likelihood of risky sexual behavior in middle adulthood (OR = 2.84, 95% CI = 1.74 - 4.64, p ≤ .001), and this relationship was mediated by criminal behavior and risky romantic relationships in young adulthood. When both factors were included in SEM, only risky relationships remained a significant mediator (indirect β = .07, p abuse and neglect for physical health, particularly sexual risk, and point to romantic relationships as an important focus of intervention and prevention efforts.

    The spread and genotypical variability of GBV-C virus were determined among the HIV-positive patients in the Russian Federation. More than a fourth (26.2%) of the HIV-infected patients were shown to have GBV-C coinfection; all virus isolates belonged to genotype 2 with a predominance of subtype 2a. Analysis of the impact of GBV-C coinfection on HIV burden and CD4 lymphocyte levels showed no significant impact on these basic characteristics of HIV infection. However, coinfection with GBV-C and HIV was associated with the higher frequency of undetectably low ( GBV-C infection to be regarded as a potentially favorable factor in HIV infection.

    The Greater Stockholm HIV Cohort Study is an initiative to provide longitudinal information regarding the health of people living with HIV. Our aim was to explore the prevalence of HIV and its association with psychiatric co-morbidities. All patients with a recorded diagnosis of HIV (any position of the ICD-10 codes B20-B24) were identified during the period 2007-2014 and related to the total population in Stockholm by January 1, 2015, N = 2.21 million. The age at diagnosis, gender, and first occurrence of an HIV diagnosis was recorded. Analyses were done by age and gender. Prevalence of psychiatric co-morbidities amongst HIV patients were recorded. Age-adjusted odds ratios with 95% confidence intervals were calculated with logistic regression for prevalent psychiatric co-morbidities in HIV infected individuals compared to the prevalence in the general population. The total prevalence of HIV was 0.16%; females 0.10% (n = 1134) and males 0.21% (n = 2448). HIV-infected people were more frequently diagnosed with psychiatric illnesses and drug abuse. In females and males with HIV-diagnosis respectively, drug dependence disorder was 7.5 (7.76% vs 1.04%) and 5.1 (10.17% vs 1.98%) times higher, psychotic disorders were 6.3 (2.65% vs 0.42%) and 2.9 (1.43% vs 0.49%) times higher, bipolar disorder was 2.5 (1.41% vs 0.57%) and 3 (1.02% vs 0.34%) times higher, depression diagnosis was 1.5 (8.47% vs 5.82%) and 3.4 (10.17% vs 2.97%) higher, trauma-related disorder was 1.5 (6.00% vs 4.10%) respectively 2.9 (4.45% vs 1.56%) times higher, anxiety disorder was 1.2 (6.88% vs 5.72%) and 2.2 (6.54% vs 2.93%) times higher than in their non-infected peers. Despite effective ART, many individuals with HIV have an impaired mental health and a history of drug abuse that may threaten the vision of a contained epidemic.

    Full Text Available 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.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.New HIV diagnoses, recent infections, acute infections and transmitted drug resistance prevalence remained stable between 2004 and 2006. Resistance to NNRTI comprised more than half of the drug-resistant cases, a worrisome finding given its role as the backbone of first-line antiretroviral therapy in San Francisco as well as worldwide.

    Despite the high prevalence of both mental disorders and HIV infection in much of sub-Saharan Africa, little is known about the occurrence of mental health disorders among HIV-infected individuals. We conducted a cross-sectional study among individuals enrolled into HIV care and treatment services near Cape Town, South Africa. Psychiatric diagnoses were measured using the Mini-International Neuropsychiatric Interview (MINI) administered by trained research nurses. In addition, all participants were administered brief rating scales for depression (the Center for Epidemiological Studies Depression Scale [CES-D]), posttraumatic stress disorder (PTSD), the Harvard Trauma Questionnaire (HTQ), and alcohol dependence/abuse (the Alcohol Use Disorders Identification Test [AUDIT]). The median age among the 465 participants was 33 years and 75% were female; 48% were receiving antiretroviral therapy. Overall, the prevalence of depression, PTSD and alcohol dependence/abuse was 14% (n = 62), 5% (n = 24), and 7% (n = 35), respectively. In multivariate analysis, the prevalence of all disorders was significantly higher among individuals who spoke Afrikaans compared to Xhosa. While the AUDIT showed excellent sensitivity and specificity in detecting MINI-defined dependence/abuse (area under the receiver-operating characteristic curve, 0.96), the HTQ and CES-D had lower performance characteristics in detecting PTSD (0.74) and depression (0.76), respectively. These data demonstrate high levels of depression, PTSD and alcohol dependence/abuse among HIV-infected individuals in this setting. Additional research is required to refine these rating scales for maximum applicability in cross-cultural populations. More generally, HIV care and treatment services represent an important venue to identify and manage individuals with common mental disorders in resource-limited settings.

    2014-07-01

    Primary HIV-1 infection covers a period of around 12 weeks in which the virus disseminates from the initial site of infection into different tissues and organs. In this phase, viremia is very high and transmission of HIV is an important issue. Most guidelines recommend antiretroviral treatment in patients who are symptomatic, although the indication for treatment remains inconclusive in asymptomatic patients. In this article the authors review the main virological and immunological events during this early phase of infection, and discuss the arguments for and against antiretroviral treatment. Recommendations of different guidelines, the issue of the HIV transmission and transmission of resistance to antiretroviral drugs, as well as recently available information opening perspectives for functional cure in patients treated in very early steps of HIV infection are also discussed.

    Non-alcoholic fatty liver disease is one of the most frequent chronic hepatic conditions worldwide. The spectrum of non-alcoholic fatty liver disease goes from hepatic steatosis to steatohepatitis, cirrhosis, and hepatocellular carcinoma. Risk factors for non-alcoholic fatty liver disease are metabolic, mainly obesity and the accompanying consequences. Treatment and prevention of non-alcoholic fatty liver disease should target those metabolic abnormalities. The frequency of and the factors associated with hepatic steatosis in HIV infection seem to be similar to those reported in the general population, though direct comparisons are lacking. Hepatic steatosis in HIV infection may also be secondary to antiretroviral drugs or HCV-related factors in HCV-coinfected subjects. However, more recent data suggest that hepatic steatosis in HIV infection represents true non-alcoholic fatty liver disease. As such, management of non-alcoholic fatty liver disease in HIV infection should follow the same principles as in the general population.

    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
