Development of an effective AIDS vaccine is crucial for the control of global human immunodeficiency virus type 1 (HIV-1) prevalence. We have developed a novel AIDS vaccine using a Sendai virus (SeV) vector and investigated its efficacy in a macaque AIDS model of simian immunodeficiency virus (SIV) infection. Its immunogenicity and protective efficacy have been shown, indicating that the SeV vector is a promising delivery tool for AIDS vaccines. Here, we describe the potential of SeV vector as a vaccine antigen delivery tool to induce effective immune responses against HIV-1 infection. PMID:26232346

Simian immunodeficiency virus (SIV) infection of newborn rhesus macaques is a practical animal model of pediatric AIDS. Intravenous inoculation of rhesus newborns with uncloned SIVmac resulted in a high virus load, no antiviral immune responses, severe immunodeficiency, and a high mortality rate within 3 months. In contrast, immediate oral zidovudine (AZT) treatment of SIV-inoculated rhesus newborns either prevented infection or resulted in reduced virus load, enhanced antiviral immune respon...

A mathematical computer model of the spread of the AIDS epidemic in the US is being developed at Los Alamos National Laboratory. This model predicts the spreading of the HIV infection, and subsequent development of clinical AIDS in various population groups. These groups are chosen according to age, frequency and type of sexual contact, population density, and region of the country. Type of sexual contact includes not only the heterosexual, homosexual differentiation but also repeated contacts with such primary partners as spouses. In conjunction with the computer model, we are developing a database containing relevant information on the natural history of the viral infection, the prevalence of the infection and of clinical AIDS in the population, the distribution of people into sexual behavior groups as a function of age and information on interregional contacts. The effects of variable infectiousness and sexual activity during the long period from infection to disease are found to have a major impact on the predictions of the model. 24 refs., 5 figs.

This study carried out to survey the relationship between personality traits and Acquired Immunodeficiency Syndrome (AIDS) in patients with human immunodeficiency virus. This case-control study was conducted on 79 AIDS patients of Triangle Clinic in Arak (case group) and 80 healthy people of Valiasr Hospital in Arak (control group). Demographic information checklist and Cloninger' Temperament and Character inventory (TCI) were two instruments applied in the study. SPSS software V.19 and tests independent t-tests, Chi squared and Spearman correlation coefficient were used for data analysis with significant level of control group was significantly higher, and there was a significant difference between two groups variables (P-0.000). The novelty seeking had the highest average in the AIDS patients with a history of addiction (M:74.00), and there was statistically significant difference between perseverance variable (P-0.021) and cooperativeness variable (P-0.041) in the two groups of AIDS patients. There was a significant relationship between novelty seeking and age at the onset of AIDS (P-0.038), harm avoidance and age at the onset of addiction (P-0.046), persistence and age at the onset of AIDS (P-0.035) and the time infected with HIV (P-0.033). It is found that two groups are different due to the personalities, so it is essential to consider the personality traits in order to prevent AIDS and also successfully treat patients suffering from AIDS.

The success of antiretroviral therapy has reduced the incidence of severe neurological complication resulting from human immunodeficiency virus (HIV) infection. However, increased patient survival has been associated with an increased prevalence of protracted forms of HIV encephalitis leading to moderate cognitive impairment. NeuroAIDS remains a great challenge to patients, their families, and our society. Thus development of preclinical models that will be suitable for testing promising new ...

Mononuclear cells were obtained from 71 human immunodeficiency virus type 1 (HIV-1) seropositive subjects presenting and first visit either as asymptomatic or with minor symptoms and with CD4 lymphocytes greater than 550 per mm3 (group A, 35 patients) or as patients with AIDS, AIDS-related illnesses, or CD4 lymphocytes less than 400 per mm3 (group B, 36 patients). After 1-5 years of follow-up, 13 patients of group A had essentially retained their initial status (asymptomatics); the 22 others had suffered clinical or immunological deterioration (progressors). Frozen cells were thawed and submitted to lethal gamma-irradiation in vitro (4500 rads; 1 rad = 0.01 Gy) before they were cultured with normal phytohemagglutinin-stimulated lymphocytes to determine radiation-resistant HIV expression ex vivo (R-HEV). HIV antigenemia correlated with R-HEV values in 142 samples (r = 0.92, P less than 0.001) but was a less sensitive predictor of disease than R-HEV. R-HEV was detected in all specimens from patients with major AIDS-related illnesses or HIV-associated CD4 lymphopenia. In 77% of the progressors from group A, R-HEV detection preceded the onset of AIDS-associated disease or CD4 lymphopenia by 1 year (average). Conversely, R-HEV was low or was not detected in 36 sequential specimens from the 13 patients who remained asymptomatic over the following 2-5 years. Thus, persistently low HIV expression in vivo predicted a nondiseased state, whereas higher HIV expression levels seemed necessary for disease to occur. These data indicate that R-HEV is related to productive HIV infection in vivo, the latter acting as a determinant of AIDS-related illnesses. In view of this, measurement of HIV expression levels in the patient should be useful in antiviral efficacy trials

Abstract Background Infection of nonhuman primates with simian immunodeficiency virus (SIV) or chimeric simian-human immunodeficiency virus (SHIV) strains is widely used to study lentiviral pathogenesis, antiviral immunity and the efficacy of AIDS vaccine candidates. SHIV challenges allow assessment of anti-HIV-1 envelope responses in primates. As such, SHIVs should mimic natural HIV-1 infection in humans and, to address the pandemic, encode HIV-1 Env components representing major viral subty...

Systemic non-Hodgkin lymphoma (S-NHL) is a common malignancy during HIV infection, and it is hypothesized that infectious agents may be involved in the etiology. Epstein-Barr virus DNA is found in pathogenesis. We analyzed AIDS-related S-NHL samples, NHL samples from HIV-negative patients, peripheral blood leukocytes from HIV-infected and -uninfected patients without NHL, and lymph nodes without tumors from HIV-infected patients. Specimens were examined by polymerase chain reaction analysis with use of primers specific for an N-terminal region of the oncoprotein large tumor antigen ( T-ag ) gene conserved among all three polyomaviruses (simian virus 40 [SV40], JC virus, and BK virus). Polyomavirus T-ag DNA sequences, proven to be SV40-specific, were detected more frequently in AIDS-related S-NHL samples (6 of 26) than in peripheral blood leukocytes from HIV-infected patients (6 of 26 vs. 0 of 69; p =.0001), NHL samples from HIV-negative patients (6 of 26 vs. 0 of 10; p =.09), or lymph nodes (6 of 26 vs. 0 of 7; p =.16). Sequences of C-terminal T-ag DNA from SV40 were amplified from two AIDS-related S-NHL samples. Epstein-Barr virus DNA sequences were detected in 38% (10 of 26) AIDS-related S-NHL samples, 50% (5 of 10) HIV-negative S-NHL samples, and 57% (4 of 7) lymph nodes. None of the S-NHL samples were positive for both Epstein-Barr virus DNA and SV40 DNA. Further studies of the possible role of SV40 in the pathogenesis of S-NHL are warranted.

Hepatopulmonary syndrome is characterized by a triad consisting of liver disorder, pulmonary vascular dilatation, and hypoxaemia. No case of hepatopulmonary syndrome associated with AIDS has been reported so far. In this study, the authors report the case of a 43-year woman with AIDS and virus C cirrhosis taking prophylactic cotrimoxazole for pneumocystosis and retroviral therapy. Upon admission, the patient presented dyspnoea, cyanosis, digital clubbing, vascular spiders, and normal chest examination. Chest X-ray revealed bilateral interstitial infiltration and evidenced increased alveolar-arterial gradient and liver function impairment. Intrapulmonary shunt was evidenced by contrast-enhanced echocardiography and radionuclide perfusion scanning, thus confirming hepatopulmonary syndrome. (author)
Full Text Available Acquired Immunodeficiency Syndrome (AIDS, a global disease, caused by the Human Immunodeficiency Virus (HIV is arguably the greatest health problem of this age and there is need to make first class information on the management of HIV/AIDS available through the use of Web-Based Technology. This paper examined the various ways of contacting HIV and the effort made by Information and Technology to make life easier for people living with the virus in Nigeria. Questionnaires were distributed to Doctors and people living with HIV/AIDS to access their knowledge and belief about the said disease. MySQL was used to generate the database, to store all the vital information about the patients, their Doctors and their complaints. PHP programming for the implementation of the interfaces, Dreamweaver HTML for the design of the web-based application, T-test and Microsoft Excel were used for the analysis of data collected. The study looked into the occupation, age range and the marital status of different categories of people living with the virus. It was discovered that there were quite large numbers of people who are living with the virus.

In late October 2014, Ebola virus disease (Ebola) was diagnosed in a humanitarian aid worker who recently returned from West Africa to New York City (NYC). The NYC Department of Health and Mental Hygiene (DOHMH) actively monitored three close contacts of the patient and 114 health care personnel. No secondary cases of Ebola were detected. In collaboration with local and state partners, DOHMH had developed protocols to respond to such an event beginning in July 2014. These protocols included safely transporting a person at the first report of symptoms to a local hospital prepared to treat a patient with Ebola, laboratory testing for Ebola, and monitoring of contacts. In response to this single case of Ebola, initial health care worker active monitoring protocols needed modification to improve clarity about what types of exposure should be monitored. The response costs were high in both human resources and money: DOHMH alone spent $4.3 million. However, preparedness activities that include planning and practice in effectively monitoring the health of workers involved in Ebola patient care can help prevent transmission of Ebola.

Full Text Available Abstract Background Infection of nonhuman primates with simian immunodeficiency virus (SIV or chimeric simian-human immunodeficiency virus (SHIV strains is widely used to study lentiviral pathogenesis, antiviral immunity and the efficacy of AIDS vaccine candidates. SHIV challenges allow assessment of anti-HIV-1 envelope responses in primates. As such, SHIVs should mimic natural HIV-1 infection in humans and, to address the pandemic, encode HIV-1 Env components representing major viral subtypes worldwide. Results We have developed a panel of clade C R5-tropic SHIVs based upon env of a Zambian pediatric isolate of HIV-1 clade C, the world's most prevalent HIV-1 subtype. The parental infectious proviral clone, SHIV-1157i, was rapidly passaged through five rhesus monkeys. After AIDS developed in the first animal at week 123 post-inoculation, infected blood was infused into a sixth monkey. Virus reisolated at this late stage was still exclusively R5 tropic and mucosally transmissible. Here we describe the long-term follow-up of this initial cohort of six monkeys. Two have remained non-progressors, whereas the other four gradually progressed to AIDS within 123–270 weeks post-exposure. Two progressors succumbed to opportunistic infections, including a case of SV40 encephalitis. Conclusion These data document the disease progression induced by the first mucosally transmissible, pathogenic R5 non-clade B SHIV and suggest that SHIV-1157i-derived viruses, including the late-stage, highly replication-competent SHIV-1157ipd3N4 previously described (Song et al., 2006, display biological characteristics that mirror those of HIV-1 clade C and support their expanded use for AIDS vaccine studies in nonhuman primates.

Activation-induced cytidine deaminase (AID), the enzyme responsible for induction of sequence variation in immunoglobulins (Igs) during the process of somatic hypermutation (SHM) and also Ig class switching, can have a potent mutator phenotype in the development of lymphoma. Using various Epstein-Barr virus (EBV) recombinants, we provide definitive evidence that the viral nuclear protein EBNA3C is essential in EBV-infected primary B cells for the induction of AID mRNA and protein. Using lymphoblastoid cell lines (LCLs) established with EBV recombinants conditional for EBNA3C function, this was confirmed, and it was shown that transactivation of the AID gene (AICDA) is associated with EBNA3C binding to highly conserved regulatory elements located proximal to and upstream of the AICDA transcription start site. EBNA3C binding initiated epigenetic changes to chromatin at specific sites across the AICDA locus. Deep sequencing of cDNA corresponding to the IgH V-D-J region from the conditional LCL was used to formally show that SHM is activated by functional EBNA3C and induction of AID. These data, showing the direct targeting and induction of functional AID by EBNA3C, suggest a novel role for EBV in the etiology of B cell cancers, including endemic Burkitt lymphoma. PMID:27217538
Full Text Available Background. HIV infection/AIDS is a social disease and morbidity in some segments of the population is threatening. One of the target organs for HIV is the nervous system. The central nervous system lesion occurring in the form of meningoencephalitison the background of HIV infection is one of the leading death causes in patients with severe immunosuppression. Objective. Reveal the typicalmorphologic changes in the central nervous system during Epstein-Barr virus meningoencephalitis in patients with HIV/AIDS. Methods. Brain tissue and meningesof deceased patients with Epstein-Barr virus meningoencephalitis. Selected 6 deaths – three women and three men, aged 28 to 34 years. Following routine procedure histologic sections were produced, which were stained with hematoxylin and eosin staining, Nissl. Results. We showed signs of development of subacute encephalitis with the presence of giant areas of demyelination by morphological study of the combination of clinical cases of HIV and Epstein-Barr virus infection. In brain tissue we identified giant cells. In addition to this significant feature of the combination of HIV and Epstein-Barr virus infection can be considered productive development of vasculitis with thrombosis and ischemic brain lesions. During histological studies in HIV-infected patients were found: infiltration of the vessel wall by leukocytes, edema and proliferative changes in the intima. All this leads to a narrowing of the lumen and thrombosis with further possible infarct, vessel rupture and hemorrhage. Conclusion. It is established that in case of damage of the central nervous system with Epstein-Barr virus in HIV patients develops subacute giant cell encephalitis with the presence of demyelination areas, a bland astrogliosis, development of productive vasculitis with thrombosis, that complicated by ischemic lesions of the brain.

Eight different protocols for immunization have been compared for the ability to raise protection against immunodeficiency virus challenges in rhesus macaques. The most promising containment of challenge infections was achieved by intradermal DNA priming followed by recombinant fowl pox virus booster immunizations. This containment did not require neutralizing antibody and was active for a series of challenges ending with a highly virulent virus with a primary isolate envelope heterologous to the immunizing strain.

The experimental determination of the electric quadrupole coupling constant of I129 enables the investigation of special problems related to the quaternery structure of the tobacco mosaic virus. Aiming information on their chemical bonds the amino acids tyrosine 139 and cysteine 27 in the tobacco mosaic virus were iodinated and the Moessbauer spectra of the probes were taken at different pH-values. The results prove the existence of a hydrogen bond at the hydroxyl group of tyrosine 139 and exclude the formation of a cystine bridge at cysteine 27 in the tobacco mosaic virus. (orig.)

Stored blood samples from 164 intravenous drug abusers who attended a Scottish general practice were tested for HTLV-III/LAV (human T cell lymphotropic virus type III/lymphadenopathy associated virus) infection. Of those tested, 83 (51%) were seropositive, which is well above the prevalence reported elsewhere in Britain and Europe and approaches that observed in New York City. The timing of taking samples of negative sera and continued drug use suggest that as many as 85% of this population might now be infected. The infection became epidemic in late 1983 and early 1984, thereafter becoming endemic. The practice of sharing needles and syringes correlated with seropositivity, which, combined with the almost exclusive intravenous use of heroin and other behavioural patterns, may explain the high prevalence of HTLV-III/LAV infection in the area. Rapid and aggressive intervention is needed to control the spread of infection. PMID:3081158

The evolution of human immunodeficiency virus type 1 (HIV-1) quasispecies at the envelope gene was studied from the time of infection in 11 men who experienced different rates of CD4+ cell count decline and 6 men with unknown dates of infection by using DNA heteroduplex mobility assays. Quasispecies were genetically homogeneous near the time of seroconversion. Subsequently, slower proviral genetic diversification and higher plasma viremia correlated with rapid CD4+ cell count decline. Except ...

Chimeric simian/human immunodeficiency virus (SHIV) consists of the env, vpu, tat, and rev genes of human immunodeficiency virus type 1 (HIV-1) on a background of simian immunodeficiency virus (SIV). We derived a SHIV that caused CD4+ cell loss and AIDS in pig-tailed macaques (S. V. Joag, Z. Li, L. Foresman, E. B. Stephens, L. J. Zhao, I. Adany, D. M. Pinson, H. M. McClure, and O. Narayan, J. Virol. 70:3189-3197, 1996) and used a cell-free stock of this virus (SHIV(KU-1)) to inoculate macaques by the intravaginal route. Macaques developed high virus burdens and severe loss of CD4+ cells within 1 month, even when inoculated with only a single animal infectious dose of the virus by the intravaginal route. The infection was characterized by a burst of virus replication that peaked during the first week following intravenous inoculation and a week later in the intravaginally inoculated animals. Intravaginally inoculated animals died within 6 months, with CD4+ counts of <30/microl in peripheral blood, anemia, weight loss, and opportunistic infections (malaria, toxoplasmosis, cryptosporidiosis, and Pneumocystis carinii pneumonia). To evaluate the kinetics of virus spread, we inoculated macaques intravaginally and euthanized them after 2, 4, 7, and 15 days postinoculation. In situ hybridization and immunocytochemistry revealed cells expressing viral RNA and protein in the vagina, uterus, and pelvic and mesenteric lymph nodes in the macaque euthanized on day 2. By day 4, virus-infected cells had disseminated to the spleen and thymus, and by day 15, global elimination of CD4+ T cells was in full progress. Kinetics of viral replication and CD4+ loss were similar in an animal inoculated with pathogenic SHIV orally. This provides a sexual-transmission model of human AIDS that can be used to study the pathogenesis of mucosal infection and to evaluate the efficacy of vaccines and drugs directed against HIV-1.

Virus-like particles (VLPs) are repetitive organizations of viral proteins assembled in an appropriate physicochemical environment. VLPs can stimulate both innate and adaptive immune responses, due to their particulate structure enabling uptake by antigen presenting cells. These characteristics have led to successful development of VLP-vaccine products, and will ensure their vast potential in years to come. Future success of VLP therapeutic products will be determined by advances in their bioengineering, and also by the development of tools to design for their stability, function and application. This review focuses on approaches for VLP assembly in controlled chemical environments in vivo and in vitro, and the application of computational tools for improved chemical sequence design, and fundamental understanding of assembly.

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.

Full Text Available Aim. The object of this study was to implement computer-aided design of the water-soluble analog of glycolipid β -galactosylceramide (β-GalCer, which presents a potential HIV-1 entry inhibitor, by the analysis of intermolecular interactions of β-GalCer with the central region of the virus envelope gp120 V3 loop followed by synthesis of this glycolipid derivative and testing for antiviral activity. Methods. To reach the object of view, computer modeling procedures, such as quantum chemical calculations, molecular docking, molecular dynamics and free energy simulations, were involved in the studies in conjunction with chemical synthesis and anti-HIV-1 assay methods. Results. As a result, the high probability of exhibiting of antiviral activity was predicted for the designed β-GalCer analog. The data of molecular modeling were confirmed by those of primary medical trials of the synthesized compound. Conclusions. In the light of the findings obtained, the designed analog of β-GalCer may be considered as the basic structure for simulation of its more potent structural forms and for posterior selection of drug candidates most promising for synthesis and anti-HIV-1 assays.

Illicit drug users sustain the epidemics of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS), hepatitis C (HCV), and sexually transmitted infections (STIs). Substance abuse treatment programs present a major intervention point in stemming these epidemics. As a part of the "Infections and Substance Abuse" study, established by the National Drug Abuse Treatment Clinical Trials Network, sponsored by National Institute on Drug Abuse, three surveys were developed; for treatment program administrators, for clinicians, and for state and District of Columbia health and substance abuse department administrators, capturing service availability, government mandates, funding, and other key elements related to the three infection groups. Treatment programs varied in corporate structure, source of revenue, patient census, and medical and non-medical staffing; medical services, counseling services, and staff education targeted HIV/AIDS more often than HCV or STIs. The results from this study have the potential to generate hypotheses for further health services research to inform public policy. PMID:16716846
Oral, intestinal and genital mucosal epithelia have a barrier function to prevent paracellular penetration by viral, bacterial and other pathogens, including human immunodeficiency virus (HIV). HIV can overcome these barriers by disrupting the tight and adherens junctions of mucosal epithelia. HIV-associated disruption of epithelial junctions may also facilitate paracellular penetration and dissemination of other viral pathogens. This review focuses on possible molecular mechanisms of HIV-associated disruption of mucosal epithelial junctions and its role in HIV transmission and pathogenesis of HIV and acquired immune deficiency syndrome (AIDS).

reported case, along with a survey of archival autopsy cases to assess baseline expression of EBV in AIDS patients. DESIGN: The case patient's autopsy material was studied exhaustively for infectious agents by culture, histochemistry, and immunohistochemistry, with negative results. Formalin-fixed paraffin......-embedded lung, spleen, lymph node, and liver tissue were further studied by in situ hybridization using a probe for EBV early RNA (EBER, Kreatech). The same method was applied to lymphoid tissues from eight other archival AIDS autopsy cases. Case patient tissues were also examined by electron microscopy...... pneumocytes. Of the archival cases studied, only one spleen was found to have rare positive lymphocytes. CONCLUSION: Primary or reactivation EBV infection may represent a previously underreported cause of morbidity and mortality in AIDS patients. Autopsy tissues from AIDS patients do not routinely show...

HIV/AIDS is increasing in prevalence in China and spread of infection from highly risk populations to the general populations was recognized. Despite the fact, there are still only few scien- tific reviews on quality of life (QOL) for people living with HIV/AIDS (PLWHAs). However, many PLWHAs are struggling with social and psychological influences such as substances abuse, cultural beliefs, depression, stigma, poverty, which can affect their QOL. Public unawareness about infection and disease, willingness to seek medical care and motivation to follow therapy are indirectly influ- encing health outcome. In 2003 Chinese government has established the so-called the "Four Frees and One Care" policy. The policy was officially implemented from 2004 in some areas, yet to date it is not implemented nationwide. This paper discussed the epidemiology of HIV, underlying psychoso- cial factors affecting PLWHAs and their impact on QOL. We put forward some recommendations for stakeholders, advocacy groups, non-government organizations and Chinese government.

Two HIV-positive male patients presented with a variety of symptoms including hemiparesis, unsteadiness, progressive loss of vision and poor memory. There were multiple non-enhancing lesions shown by CT scan in the white matter of the cerebral hemispheres. Specimens obtained by burr-hole biopsy showed the features of progressive multifocal leucoencephalopathy (PML) in both cases. Electron microscopy demonstrated round and rod shaped particles of papovavirus in the nuclei and cytoplasm of oligodendrocytes and in processes of astrocytes where abnormal and florid modes of viral replication were seen. Additional features observed were viral particles suggestive of an enterovirus in Case 1 and, in both specimens, massive membrane proliferation within both nuclei and cytoplasm of infected cells together with the presence of tubuloreticular structures (TRS) in the cytoplasm of endothelial cells. At post-mortem, the brain of patient 2 showed PML and HIV encephalitis. The presence of HIV was confirmed by immunohistochemical methods. We suggest that in AIDS patients the abnormality of the immune system induced by HIV causes abnormal replication patterns of papovavirus in the brain. In addition, these cases confirm the frequent occurrence in AIDS patients of TRS, now considered to be a marker for HIV. PMID:2555730

Full Text Available Abstract Background Treatment of feline immunodeficiency virus (FIV infection has been hampered by the absence of a specific combination antiretroviral treatment (ART. Integrase strand transfer inhibitors (INSTIs are emerging as a promising new drug class for HIV-1 treatment, and we evaluated the possibility of inhibiting FIV replication using INSTIs. Methods Phylogenetic analysis of lentiviral integrase (IN sequences was carried out using the PAUP* software. A theoretical three-dimensional structure of the FIV IN catalytic core domain (CCD was obtained by homology modeling based on a crystal structure of HIV-1 IN CCD. The interaction of the transferred strand of viral DNA with the catalytic cavity of FIV IN was deduced from a crystal structure of a structurally similar transposase complexed with transposable DNA. Molecular docking simulations were conducted using a genetic algorithm (GOLD. Antiviral activity was tested in feline lymphoblastoid MBM cells acutely infected with the FIV Petaluma strain. Circular and total proviral DNA was quantified by real-time PCR. Results The calculated INSTI-binding sites were found to be nearly identical in FIV and HIV-1 IN CCDs. The close similarity of primate and feline lentivirus IN CCDs was also supported by phylogenetic analysis. In line with these bioinformatic analyses, FIV replication was efficiently inhibited in acutely infected cell cultures by three investigational INSTIs, designed for HIV-1 and belonging to different classes. Of note, the naphthyridine carboxamide INSTI, L-870,810 displayed an EC50 in the low nanomolar range. Inhibition of FIV integration in situ was shown by real-time PCR experiments that revealed accumulation of circular forms of FIV DNA within cells treated with L-870,810. Conclusion We report a drug class (other than nucleosidic reverse transcriptase inhibitors that is capable of inhibiting FIV replication in vitro. The present study helped establish L-870,810, a compound
In this study, the authors have investigated the potential mechanisms responsible for the loss of human immunodeficiency virus type 1 (HIV-1)-specific cytolytic activity in the advanced stages of HIV-1 infection. They have demonstrated that HIV-1-specific cytotoxic T lymphocytes are predominantly contained within the CD8+DR+ subset. Furthermore, they have shown by a redirected killing assay that there is a dichotomy between HIV-1-specific cytolytic activity and broad cytolytic potential since the cytolytic machinery of CD8+DR+ cells is still functioning even in patients with AIDS who have lost their HIV-1-specific cytolytic activity. In addition, by comparative analysis of these two types of cytolytic activity over time they have demonstrated a progressive loss of HIV-1-specific cytolytic activity in the advanced stages of the disease, whereas the cytolytic potential remained unchanged regardless of the clinical stage. On the basis of these results, they propose that the loss of HIV-1-specific cytolytic activity in HIV-1-infected individuals may result at least in part from a progressive decrease in the pool of HIV-1-specific cytotoxic T lymphocytes belonging to the CD8+DR+ subset whose ability to expand has been impaired

Background: As more and more people with human immunodeficiency virus (HIV) live longer and healthier lives because of antiretroviral therapy (ART), an increasing number of sexual transmissions of HIV may arise from these people living with HIV/AIDS (PLWHA). Hence, this study is conducted to assess the predictors of unsafe sexual behavior among PLWHA on ART in Western India. Materials and Methods: The current cross-sectional study was carried out among 175 PLWHAs attending ART center of a Tertiary Care Hospital in Western India. Unsafe sex was defined as inconsistent and/or incorrect condom use. A total of 39 variables from four domains viz., sociodemographic, relationship-related, medical and psycho-social factors were studied for their relationship to unsafe sexual behavior. The variables found to be significantly associated with unsafe sex practices in bivariate analysis were explored by multivariate analysis using multiple logistic regression in SPSS 17.0 version. Results: Fifty-eight percentage of PLWHAs were practicing unsafe sex. 15 out of total 39 variables showed significant association in bivariate analysis. Finally, 11 of them showed significant association in multivariate analysis. Young age group, illiteracy, lack of counseling, misbeliefs about condom use, nondisclosure to spouse and lack of partner communication were the major factors found to be independently associated with unsafe sex in multivariate analysis. Conclusion: Appropriate interventions like need-based counseling are required to address risk factors associated with unsafe sex.

Full Text Available Abstract Background Data on the evolution of natural SIV infection in chimpanzees (SIVcpz and on the impact of SIV on local ape populations are only available for Eastern African chimpanzee subspecies (Pan troglodytes schweinfurthii, and no data exist for Central chimpanzees (Pan troglodytes troglodytes, the natural reservoir of the ancestors of HIV-1 in humans. Here, we report a case of naturally-acquired SIVcpz infection in a P.t.troglodytes chimpanzee with clinical and biological data and analysis of viral evolution over the course of infection. Results A male chimpanzee (Cam155, 1.5 years, was seized in southern Cameroon in November 2003 and screened SIV positive during quarantine. Clinical follow-up and biological analyses have been performed for 7 years and showed a significant decline of CD4 counts (1,380 cells/mm3 in 2004 vs 287 in 2009, a severe thrombocytopenia (130,000 cells/mm3 in 2004 vs 5,000 cells/mm3 in 2009, a weight loss of 21.8% from August 2009 to January 2010 (16 to 12.5 kg and frequent periods of infections with diverse pathogens. DNA from PBMC, leftover from clinical follow-up samples collected in 2004 and 2009, was used to amplify overlapping fragments and sequence two full-length SIVcpzPtt-Cam155 genomes. SIVcpzPtt-Cam155 was phylogenetically related to other SIVcpzPtt from Cameroon (SIVcpzPtt-Cam13 and Gabon (SIVcpzPtt-Gab1. Ten molecular clones 5 years apart, spanning the V1V4 gp120 env region (1,100 bp, were obtained. Analyses of the env region showed positive selection (dN-dS >0, intra-host length variation and extensive amino acid diversity between clones, greater in 2009. Over 5 years, N-glycosylation site frequency significantly increased (p Conclusions Here, we describe for the first time the clinical history and viral evolution of a naturally SIV infected P.t.troglodytes chimpanzee. The findings show an increasing viral diversity over time and suggest clinical progression to an AIDS-like disease, showing that

The relation between insulin resistance (IR) and coronary artery disease in patients with human immunodeficiency virus (HIV) infection remains incompletely defined. Fasting serum insulin and glucose measurements from 448 HIV-infected and 306 uninfected men enrolled in the Multicenter AIDS Cohort Study were collected at semiannual visits from 2003 to 2013 and used to compute the homeostatic model assessment of IR (HOMA-IR). Coronary computed tomographic angiography (CTA) was performed at the end of the study period to characterize coronary pathology. Associations between HOMA-IR (categorized into tertiles and assessed near the time of the CTA and over the 10-year study period) and the prevalence of coronary plaque or stenosis ≥50% were assessed with multivariate logistic regression. HOMA-IR was higher in HIV-infected men than HIV-uninfected men when measured near the time of CTA (3.2 vs 2.7, p = 0.002) and when averaged over the study period (3.4 vs 3.0, p <0.001). The prevalence of coronary stenosis ≥50% was similar between both groups (17% vs 15%, p = 0.41). Both measurements of HOMA-IR were associated with greater odds of coronary stenosis ≥50% in models comparing men with values in the highest versus the lowest tertiles, although the effect of mean HOMA-IR was stronger than the single measurement of HOMA-IR before CTA (odds ratio 2.46, 95% CI 1.95 to 3.11, vs odds ratio 1.43, 1.20 to 1.70). This effect was not significantly modified by HIV serostatus. In conclusion, IR over nearly a decade was greater in HIV-infected men than HIV-uninfected men, and in both groups, was associated with significant coronary artery stenosis. PMID:26830260

Acquired immunodeficiency syndrome (AIDS) is believed to have begun in Rwanda with the transmission of green monkey virus to humans; the virus spread among prostitutes and truck drivers along the highways and then to the cities. In the most threatened areas, for example, Kinshasa in Zaire, 20% of the inhabitants are infected. 8% of pregnant women are human immunodeficiency virus (HIV)-positive. Social conditions are important. In Kenya prostitutes who work along the highways are carriers of socially transmitted diseases and genital sores. They are 60-80% HIV-positive. The better-off prostitutes at bars and hotels enjoy better health and fewer contacts and are 30% HIV-positive. It should be possible to develop a vaccine against the AIDS virus, but only a few virologists believe that this can be done within 10 years. Because HIV virus mutates rapidly, many different vaccines would have to be prepared. About 80 countries are cooperating with the World Health Organization to combat HIV and AIDS in Africa. Traveling and working abroad is beginning to be a problem. 15 countries have introduced restrictions on foreign visitors. Swedish midwives have an important role to play in fighting HIV. Their youth counseling activities can spread information about HIV and AIDS. Children who are in early stages of sexuality are probably the most important group to be influenced. It is already too late to begin informing 15-17 year olds about the disease. Midwives should probably be starting much sooner, perhaps even with 10-year olds. PMID:3692943

Controversy over the aggregate impact of foreign aid has focused on reduced form estimates of the aid-growth link. The causal chain, through which aid affects developmental outcomes including growth, has received much less attention. We address this gap by: (i) specifying a structural model of the...... main relationships; (ii) estimating the impact of aid on a range of final and intermediate outcomes; and (iii) quantifying a simplied representation of the full structural form, where aid impacts on growth through key intermediate outcomes. A coherent picture emerges: aid stimulates growth and reduces...

The scientific debate between pros and cons of the HIV criminal theory of AIDS still remains unsettled. The purpose of this review is to promote resolution of the problem by extracting a common principle of the host-virus relation using data resources for each of 4 viruses as follows: a) polyoma virus, b) Marek's disease virus, c) Ebola virus, d) Korean hemorrhagic fever virus. Conclusions drawn from this study are given as follows: i) Environment emerged as the cardinal factor to modify the process of virus infection in all of the 4 viruses studied. Above all, an accelerating effect of environmental stress on the progression of virus infection was noted in vivo in the majority of viral diseases. ii) Evidence is available to indicate that a healthy cell (or a healthy individual) may harbor virus genes of multiple species without manifesting any pathologic sign. iii) Evidence also suggests that the biological property as well as morphological structure of a virus may vary in reponse to a change of the bioenvironment. On the basis of the above information, we propose to renounce 2 assumptions of classical infection model: a) the hereditarily determined virulence of a microorganism (including virus) be the sole determinant of infection to the effect that its invasion into the host should automatically complete the programmed course of infection; b) virus, a quasi-living creature, should reserve its behavioral independence irrespective of a change of the bioenvironment. The new infection model was constructed on the basis of the selfish gene concept that had been invented by Richard Dawkins to explain the altruistic behavior of an individual. That is, the fate of an exogenous or endogenous virus is under the dual control of the host genome (selfish gene) and the outer environment. The progression of virus infection is conditioned by a crosstalk between them. The selfish gene may use virus (a lifeless substance) as a magic bullet to induce a designated host response. In

This article discusses the acquired immunodeficiency syndrome (AIDS) epidemic an its effect on developing countries, with emphasis on Africa. The AIDS death toll will be high in the US: 180,000 by 1991, but it will be in the millions in developing countries. In Africa, AIDS is mainly transmitted heterosexually, is as prevalent among women as among men, and is taking a serious toll among professional classes and young wage earners. The social costs of funerals has increased, and company clinics and sick pay funds have been overwhelmed. In Uganda, the epidemic adds to the state of psychological shock people have sufferred because of the civil war. Medical professionals have been hard-pressed to acquire equipment for testing blood for the virus, although there have been efforts to protect blood supplies through exhaustive testing. Endemic tuberculosis becomes an even more serious problem in developing countries, since AIDS lowers resistance to it. AIDS also effects many developing country children, usually through infected mothers, who can transmit AIDS through breast milk or during pregnancy of birth. This poses a dilemma for promoters of breastfeeding. It is also feared that innoculation of immunosuppressed children may be dangerous. The global picture suggests that Africa is hardest hit: seropositivity prevalence ranges from 0.7% of Congo blood donors to 33% of male donors in Lusaka Zambia. Brazil's cases are mainly homosexual, and in Asia the prevalence is mostly low, although there is a great potential danger in countries where prostitution and heroin addiction are prevalent. The only effective weapon against AIDS is education and blood testing to prevent spread. Despite good education programs in some countries, e.g. Rwanda, there is still widespread ignorance of how AIDS is spread. PMID:12314457

The potential benefit of using unmethylated CpG oligoribodeoxynucleotides (ODN) as an adjuvant in a therapeutic simian immunodeficiency virus (SIV) vaccine consisting of AT2-inactivated SIVmac239 was evaluated in SIV-infected rhesus macaques receiving antiretroviral therapy (ART). We hypothesized that using CpG ODN as an adjuvant in therapeutic vaccination would enhance SIV-specific immune responses and suppress SIV replication after ART was stopped. To test our hypothesis, we immunized chron...

The Indian Health Organization projected the number of deaths per day due to AIDS by the year 2000 at 10,000. An interdisciplinary international conference was held in New Delhi to draft an international law governing the issues related to AIDS. Human freedom and public health policies are the most affected by this disease. In the absence of an international AIDS law, judicial verdicts set precedents and could have serious ramifications. A participant from the John Marshall Law School, Chicago, suggested that instead of making new laws, the existing ones from the colonial past should be repealed. This includes Section 377 of the Indian Penal Code, which provides criminal sanctions against those who indulge in unnatural relations with man, woman, or animal. Penalizing homosexuality will only perpetuate clandestine relations and spread the virus into their families. Another participant seconded this motion stating that even a sex worker must be protected from abuse and indignity. The National AIDS Control Organization responded to the criticism that the government had not utilized all the World Bank funds allocated for anti-AIDS projects. The trends of the epidemic were the most important indicators not just the numbers. In Manipur and Mizoram, infection was almost entirely due to injecting drug use. The Saheli project undertaken in the red-light areas of Bombay encompassed brothel owners and prostitutes, which could be replicated in other areas. Because existing government policies were focusing on prevention, there was no protection of an HIV-infected individual's privacy, one participant from Madras stated. The confidentiality issue was also echoed by a US participant. The New Delhi Declaration and Action Plan on HIV/AIDS was also discussed. It forbids discrimination in employment, education, housing, health care, social security, travel, and marital and reproductive rights. Providing sterile needles and ensuring the safety of the blood supply were other concerns

AIDS associated malignancies (ARL) is a major complication associated with AIDS patients upon immunosuppression.Chronically immunocompromised patients have a markedly increased risk of developing lymphoproliferative disease. In the era of potent antiretrovirals therapy (ARV), the malignant complications due to HIV- 1 infection have decreased in developed nations where ARV is administered, but still poses a major problem in developing countries where HIV- 1incidence is high and ARV is still not yet widely available. Even in ARV treated individuals there is a concern that the prolonged survival of many HIV- 1 carriers is likely to eventually result in an increased number of malignancies diagnosed.Malignancies that were found to have high incidence in HIV-infected individuals are Kaposi's sarcoma (KS), Hodgkin's disease (HD) and non-Hodgkin's lymphoma (NHL). The incidence of NHL has increased nearly 200 fold in HIV-positive patients, and accounts for a greater percentage of AIDS defining illness in the US and Europe since the advent of HAART therapy. These AIDS related lymphomas are distinct from their counterparts seen in HIV- 1 seronegative patients.For example nearly half of all cases of ARL are associated with the presence of a gamma herpesvirus, Epstein Barr virus (EBV) or human herpesvirus-8 (HHV-8)/Kaposi's sarcoma associated herpesvirus (KSHV). The pathogenesis of ARLs is complex. B-cell proliferation driven by chronic antigenemia resulting in the induction of polyclonal and ultimately monoclonal lymphoproliferation may occur in the setting of severe immunosuppression.

Response of a simian immunodeficiency virus (SIVmac251 to raltegravir: a basis for a new treatment for simian AIDS and an animal model for studying lentiviral persistence during antiretroviral therapy
Full Text Available Abstract Background In this study we successfully created a new approach to ART in SIVmac251 infected nonhuman primates. This drug regimen is entirely based on drugs affecting the pre-integration stages of replication and consists of only two nucleotidic/nucleosidic reverse transcriptase inhibitors (Nt/NRTIs and raltegravir, a promising new drug belonging to the integrase strand transfer inhibitor (INSTI class. Results In acutely infected human lymphoid CD4+ T-cell lines MT-4 and CEMx174, SIVmac251 replication was efficiently inhibited by raltegravir, which showed an EC90 in the low nanomolar range. This result was confirmed in primary macaque PBMCs and enriched CD4+ T cell fractions. In vivo monotherapy with raltegravir for only ten days resulted in reproducible decreases in viral load in two different groups of animals. When emtricitabine (FTC and tenofovir (PMPA were added to treatment, undetectable viral load was reached in two weeks, and a parallel increase in CD4 counts was observed. In contrast, the levels of proviral DNA did not change significantly during the treatment period, thus showing persistence of this lentiviral reservoir during therapy. Conclusions In line with the high conservation of the three main amino acids Y143, Q148 and N155 (responsible for raltegravir binding and molecular docking simulations showing similar binding modes of raltegravir at the SIVmac251 and HIV-1 IN active sites, raltegravir is capable of inhibiting SIVmac251 replication both in tissue culture and in vivo. This finding may help to develop effective ART regimens for the simian AIDS model entirely based on drugs adopted for treatment in humans. This ART-treated AIDS nonhuman primate model could be employed to find possible strategies for virus eradication from the body.
In 1993, 10 years after realizing that AIDS posed a threat to the future of mankind, social mobilization will improve the odds against AIDS. The objective is to create awareness about the virus, and to affect positive behavioral change through advocacy, communication, and grass-roots actions. The first goal is to change the societal attitude about the status of youth and women in order to understand that gender inequality fuels the pandemic. They are the most vulnerable groups, therefore their economic and social power must be improved. The Convention on the Rights of the Child and the Convention on the Elimination of All Forms of Discrimination against Women constitute a platform for broader action by governmental, nongovernmental, and religious institutions. In addition, these organizations need strong allies in society: 1) the media, which can communicate the importance of youth, women, and attitudes in the epidemic; 2) religious leaders, who can be powerful sources of advocacy for change in attitudes as well as support and care for AIDS-affected individuals and families; 3) policy makers, who can be crucial in changing existing policies and altering the allocation of government resources to youth and women; 4) human rights organizations, which play an important role in promoting the concept of health as a human right and for enhancing the understanding of AIDS in the context of discrimination and poverty; 5) the private sector, including commerce and industry, which can promote changes in attitude within the work force and AIDS prevention initiatives; and 6) parent-teacher groups and models for youth, who can educate them about socially acceptable and unacceptable behavior and can empower them to make responsible behavior choices.

The World Health Organization has announced that within 3 years 10% of Tanzania's population of 26 million will be infected with the human immunodeficiency virus (HIV). But there is some faint hope in the research of Tanzanian traditional medicine. An almost 90-year-man, Waziri Mrisho, is credited with having treated AIDS patients successfully with herbs that strengthen the immune system. Margaret Nakamya was stricken by the symptoms of AIDs in March 1990. She was referred to Waziri and started using his herbs. 3 years later she weighs 49 kg compared to 40 kg before. The old man's son set up a little factory where he pulverizes herbs and sells them at the price he can command The 3 types of trees that the herbal medicine is taken from grow in the wild, but some have also been planted around the factory. Even if these herbs are effective, it will take years before the AIDS epidemic is over, when people have changed their lifestyles. The means of communication (TV, cinema, radio, telephone) are missing or inadequate. In the Kagera region, with 1.2 million inhabitants, 25% of pregnant women are HIV-infected and 65,000 children lost their parents to AIDS. There are 2000 children in Dar Es Salaam living in the streets. The Anglican St. Albans Church runs a center for street kids where they get meals 3 times a week. The nurse Ruth Nesje enlisted a Norwegian physician and homeopath in a research project involving 30 AIDS patients in Norway. The University in Bergen will do in vitro testing. One group of patients will receive both AZT and the herbs, another group will get only AZT, and the 3rd group will obtain only the herbs. The Norwegian Nursing Association, NORAD, and DANIDA also plan various projects in the Tanga region. PMID:8499187
Neville Hodgkinson, a British journalist, has written a book in which he argues that AIDS is not caused by HIV alone, if at all. Hodgkinson further posits that AIDS has always been, and still is, a gay and heavy drug users' problem, and that no deadly epidemic of AIDS exists in Africa. Even the HIV serodiagnosis test is flawed. International clamor and intensive research efforts over the HIV/AIDS pandemic have just been part of a deadly deception. Hodgkinson has written and published a book in which his arguments are presented. Hodgkinson claims that this false paradigm of AIDS causation is harming patients, the public, and public resources, and that a new approach is urgently needed to establish the true causes of AIDS and how to prevent and treat them. However, researchers and health professionals worldwide refuse to reorient their research for fear of losing research funding and their livelihoods. No cure exists for AIDS only because researchers have been studying the wrong virus. PMID:12291687

[Consensus document of Gesida and Spanish Secretariat for the National Plan on AIDS (SPNS) regarding combined antiretroviral treatment in adults infected by the human immunodeficiency virus (January 2012)].
This consensus document has been prepared by a panel consisting of members of the AIDS Study Group (Gesida) and the Spanish Secretariat for the National Plan on AIDS (SPNS) after reviewing the efficacy and safety results of clinical trials, cohort and pharmacokinetic studies published in medical journals, or presented in medical scientific meetings. Gesida has prepared an objective and structured method to prioritise combined antiretroviral treatment (cART) in naïve patients. Recommendations strength (A, B, C) and the evidence which supports them (I, II, III) are based on a modification of the Infectious Diseases Society of America criteria. The current antiretroviral treatment (ART) of choice for chronic HIV infection is the combination of three drugs. ART is recommended in patients with symptomatic HIV infection, in pregnancy, in serodiscordant couples with high transmission risk, hepatitis B fulfilling treatment criteria, and HIV nephropathy. Guidelines on ART treatment in patients with concurrent diagnosis of HIV infection and an opportunistic type C infection are included. In asymptomatic patients ART is recommended on the basis of CD4 lymphocyte counts, plasma viral load and patient co-morbidities, as follows: 1) therapy should be started in patients with CD4 counts cells/μL; 2) when CD4 counts are between 350 and 500 cells/μL, therapy will be recommended and only delayed if patient is reluctant to take it, the CD4 are stabilised, and the plasma viral load is low; 3) therapy could be deferred when CD4 counts are above 500 cells/μL, but should be considered in cases of cirrhosis, chronic hepatitis C, high cardiovascular risk, plasma viral load >10(5) copies/mL, proportion of CD4 cells 55 years. ART should include 2 reverse transcriptase inhibitors nucleoside analogues and a third drug (non-analogue reverse transcriptase inhibitor, ritonavir boosted protease inhibitor or integrase inhibitor). The panel has consensually selected and given priority to using
In this update, antiretroviral therapy (ART) is recommended for all patients infected by type 1 human immunodeficiency virus (HIV-1). The objective of ART is to achieve an undetectable plasma viral load (PVL). Initial ART should comprise 3 drugs, namely, 2 nucleoside reverse transcriptase inhibitors (NRTI), and 1 drug from another family. Four of the recommended regimens, all of which have an integrase strand transfer inhibitor (INSTI) as the third drug, are considered a preferred regimen; a further 6 regimens, which are based on an INSTI, a non-nucleoside reverse transcriptase inhibitor (NNRTI), or a protease inhibitor boosted with cobicistat or ritonavir (PI/COBI, PI/r), are considered alternatives. The reasons and criteria for switching ART are presented both for patients with an undetectable PVL and for patients who experience virological failure, in which case the rescue regimen should include 3 (or at least 2) drugs that are fully active against HIV. The specific criteria for ART in special situations (acute infection, HIV-2 infection, pregnancy) and comorbid conditions (tuberculosis and other opportunistic infections, kidney disease, liver disease, and cancer) are updated.

Highly attenuated rabies virus (RV) vaccine vectors were evaluated for their ability to protect against highly pathogenic SIVmac251 challenge. Mamu-A*01 negative rhesus macaques were immunized in groups of four with either: RV expressing SIVmac239-GagPol, a combination of RV expressing SIVmac239-Env and RV expressing SIVmac239-GagPol, or with empty RV vectors. Eight weeks later animals received a booster immunization with a heterologous RV expressing the same antigens. At twelve weeks post-boost, all animals were challenged intravenously with 100 TCID50 of pathogenic SIVmac251-CX. Immunized macaques in both vaccine groups had 1.3–1.6-log fold decrease in viral set point compared to control animals. The GagPol/Env immunized animals also had a significantly lower peak viral load. When compared to control animals following challenge, vaccinated macaques had a more rapid induction of SIVmac251 neutralizing antibodies and of CD8+ T cell responses to various SIV epitopes. Moreover, vaccinated macaques better-maintained peripheral memory CD4+ T cells and were able to mount a poly-functional CD8+ T cell response in the mucosa. These findings indicate promise for RV-based vectors and have important implications for the development of an efficacious HIV vaccine. PMID:19879223

Viruses are known to cause many diseases, from the common cold and cold sores to more serious diseases such as the Ebola virus disease and AIDS. Viruses have evolved different strategies to enter and infect cells. In order to infect a cell, viruses have to overcome the cell membrane barrier to deliver their genome to the site of replication. Enveloped viruses can either fuse directly at the plasma membrane or with an endosomal membrane after endocytic uptake. In this work, I studied the early...
The update of these adult antiretroviral treatment (cART) recommendations has been carried out by consensus of a panel consisting of members of the Grupo de Estudio de Sida (Gesida, AIDS Study Group) and the Plan Nacional sobre el Sida (PNS, Spanish AIDS Plan) who have reviewed the antiretroviral efficacy and safety advances in clinical trials, cohort and pharmacokinetic studies published in medical journals (PubMed and Embase), or presented in medical scientific meetings. Three levels of evidence were defined according to the data source: randomized studies (level A), cohort or case-control studies (level B), and expert opinion (level C). The decision to recommend, consider or not to recommend antiretroviral treatment (ART) was established by consensus in each situation. The current treatment of choice for HIV infection is the combination of three drugs. Combined ART is recommended in patients with symptomatic HIV infection, and guidelines on this treatment in patients with an opportunistic type C infection are included. In asymptomatic patients, initiation of ART is recommended on the basis of CD4 lymphocyte counts, plasma viral load and patient co-morbidities, as follows: a) therapy should be started in patients with CD4 counts cells/μL; b) Therapy should be recommended when CD4 counts are between 350 and 500 cells/μL, except when CD4 are stabilized, there is low plasma viral load, or the patient not willing; c) Therapy could be deferred when CD4 counts are above 500 cells/ μL, but should be considered in cases of cirrhosis, chronic hepatitis C, hepatitis B fulfilling treatment criteria, high cardiovascular risk, HIV nephropathy, viral load > 100,000 copies/ mL, proportion of CD4 cells 55 years, and in cases of discordant serological sexual couples in order to reduce transmission. cART should include 2 reverse transcriptase inhibitor nucleoside analogues (AN) and a non-analogue reverse transcriptase inhibitor (NN) or 2 AN and a ritonavir boosted protease

The interaction of gold nanoparticles (AuNP) with human immune-deficiency virus aspartic protease (HIVPR) is modelled using a regime of molecular dynamics simulations. The simulations of the ‘docking’, first as a rigid-body complex, and eventually through flexible-fit analysis, creates 36 different complexes from four initial orientations of the nanoparticle strategically positioned around the surface of the enzyme. The structural deviations of the enzymes from the initial x-ray crystal structure during each docking simulation are assessed by comparative analysis of secondary structural elements, root mean square deviations, B-factors, interactive bonding energies, dihedral angles, radius of gyration (R g), circular dichroism (CD), volume occupied by C α , electrostatic potentials, solvation energies and hydrophobicities. Normalisation of the data narrows the selection from the initial 36 to one ‘final’ probable structure. It is concluded that, after computer simulations on each of the 36 initial complexes incorporating the 12 different biophysical techniques, the top five complexes are the same no matter which technique is explored. The significance of the present work is an expansion of an earlier study on the molecular dynamic simulation for the interaction of HIVPR with silver nanoparticles. This work is supported by experimental evidence since the initial ‘orientation’ of the AgNP with the enzyme is the same as the ‘final’ AuNP-HIVPR complex generated in the present study. The findings will provide insight into the forces of the binding of the HIVPR to AuNP. It is anticipated that the protocol developed in this study will act as a standard process for the interaction of any nanoparticle with any biomedical target.

Several studies have found reductions in acquired immunodeficiency syndrome (AIDS) risk practices among gay men in high AIDS-prevalence cities since the start of the AIDS crisis. Much less is known about risk behavior patterns among gay men in smaller cities, where AIDS cases are less common and the prevalence of human immunodeficiency virus infection is relatively lower. In the study, men entering gay bars in three cities, one large and two small, completed anonymous surveys of sexual practi...

Full Text Available Abstract In the history of public health, HIV/AIDS is unique; it has widespread and long-lasting demographic, social, economic and political impacts. The global response has been unprecedented. AIDS exceptionalism - the idea that the disease requires a response above and beyond "normal" health interventions - began as a Western response to the originally terrifying and lethal nature of the virus. More recently, AIDS exceptionalism came to refer to the disease-specific global response and the resources dedicated to addressing the epidemic. There has been a backlash against this exceptionalism, with critics claiming that HIV/AIDS receives a disproportionate amount of international aid and health funding. This paper situations this debate in historical perspective. By reviewing histories of the disease, policy developments and funding patterns, it charts how the meaning of AIDS exceptionalism has shifted over three decades. It argues that while the connotation of the term has changed, the epidemic has maintained its course, and therefore some of the justifications for exceptionalism remain.

Full Text Available Tactile aids, which translate sound waves into vibrations that can be felt by the skin, have been used for decades by people with severe/profound hearing loss to enhance speech/language development and improve speechreading.The development of tactile aids dates from the efforts of Goults and his co-workers in the 1920s; Although The power supply was too voluminous and it was difficult to carry specially by children, it was too huge and heavy to be carried outside the laboratories and its application was restricted to the experimental usage. Nowadays great advances have been performed in producing this instrument and its numerous models is available in markets around the world.
In a television broadcast, Deputy President Mbeki of South Africa announced a campaign against HIV/AIDS that would involve coordination between various government departments and nongovernmental organizations. Mbeki, who is associated with Virodene (a drug treatment for AIDS that is considered a scam), replaced President Mandela at the last minute in the broadcast. Two days after the broadcast, the government refused to support treatment of pregnant women infected with HIV with zidovudine to prevent transmission of the virus to the baby. The treatment is considered cost-effective by AIDS workers and public health officials. According to Mark Heywood of the AIDS law project at Witwatersrand University, 16% of pregnant women attending antenatal clinics were HIV-positive in 1997; this means that about 3 million South Africans (8% of the population) were living with HIV. Heywood said that the government believes there are 1500 new cases daily. By the end of 1998, 3.5 million South Africans will be living with HIV. Although the government is asking other sectors to join in the campaign, what the government is doing is unclear. Mother-to-child transmission of HIV is second only to transmission of the virus through heterosexual sex in South Africa. PMID:9841037

AIDS was first defined in the United States in 1981. It spreads to nearly all the countries of the world with a great speed and can infect everbody without any differantiation. The infection results in death and there is no cure or vaccine for it, yet. To data given to World Health Organization until July-1994, it is estimated that there are about 1 million patients and about 22 millions HIV positive persons In the world. Sixty percent of HIV positive persons are men and 40% are women. The di...

Infection with the human immunodeficiency virus (HIV) is often associated with the acquired immunodeficiency syndrome (AIDS), and wasting is one of the defining clinical features of AIDS. Muscular weakness due to myopathy may develop at any stage of HIV infection. We report two illustrative cases of HIV-associated myopathies. One was due to inflammatory myosits most likely directly related to the HIV infection, and the other was most likely the result of mitochondrial damage due to zidovudine, a nucleoside analogue commonly used in treating HIV infection. Biopsies from both patients showed alterations of myofiber structures, of varying severity, culminating in necrosis, lipid droplets, and lymphoplasmocytic inflammatory response. The zidovudine-treated patient also showed distinctive mitochondrial changes, predominantly enlargement, variation in shape and size, and disorganization of the cristae. These two types of HIV-associated inflammatory myopathies are reviewed, along with other HIV-associated myopathies, including HIV wasting syndrome, nemaline rod myopathy, pyomyositis, rhabdomyolysis, cardiomyopathy, and other miscellaneous myopathies associated with HIV infection.

Morphological imaging, based on the use of various techniques including ultrasound, X-ray computed tomography (CT), and magnetic resonance imaging (MRI), plays an important role in the characterization, diagnosis and follow-up of patients with Human Immunodeficiency Virus (HIV) infection and Acquired Immunodeficiency Syndrome (AIDS). While the presence of thoracic infections, the most frequently observed illnesses in AIDS patients, can best be performed by using conventional chest films and CT, the assessment of cerebral involvement in AIDS patients - characterized by the presence of focal masses, demyelination, meningitis, and infarction - is best achieved using MRI. The work-up of patients with gastrointestinal symptoms should include the use of ultrasound for the evaluation of visceral involvement and lymphadenopathy, completed by CT to further characterize pathologic conditions in either the bowel or visceral organs. Ultrasound is the screening exam of choice in AIDS patients with suspected renal disease, but other methods may be necessary for the assessment of the complications due to pharmacological treatment. Musculoskeletal complications may require the combined use of all the above methods, since they may be caused by infections, tumors and rheumatologic illness. The use of the radiographic methods for the detection of the numerous forms of infections and malignancies in AIDS patients is described in detail for the various body districts

Migration is a domain of human behavior implicated in the spread of AIDS that has been largely neglected in research and prevention campaigns. Recognition of the role of mobility in the spread of AIDS has been largely anecdotal, as in the case of East African truck drivers. Like sexuality, mobility is a fundamental human behavior and very difficult to modify. Now that the AIDS epidemic has become worldwide, the importance of mobility in its spread is clear. Movement in space allowed the virus to be transported to new populations. The spread of the virus is then determined by sexual behavior. Population movements in Africa occur from one rural area or city to another, or between the city and the countryside. The view that AIDS is primarily an urban phenomenon ignores on the one hand return migration of migratory labor or other circuits between the city and countryside, and on the other the significant mobility from one rural area to another, such as that of seasonal plantation workers. Other forms of movement are also very important in Africa, which has more refugees and displaced persons than any other continent. Various armed conflicts involve movement, as does the international drug traffic. Each of these types of movement has tended to increase in recent years because of political instability or economic crisis. Exposure to risk of HIV infection consequently also increases. Officials of some national AIDS control programs have begun to cooperate with each other. Although the epidemic has spread widely, it has not reached its peak even in Africa, especially in rural areas. Systematic interventions at strategic points of migratory currents would be very useful in prevention. PMID:12178209
Full Text Available Human immunodeficiency virus and the acquired immunodeficiency syndrome (HIV/AIDS have greatly complicated dermatologic disease and the required care in most regions of Africa. Opportunistic infections, ectoparasites, Kaposi sarcoma, and skin manifestations of systemic infections are exceedingly common in patients with HIV/AIDS. Dermatologists have contributed significantly to our knowledge base about HIV/AIDS and have played an important educational role regarding the clinical manifestations historically. Because of the increased burden of skin disease in Africa due to the HIV/AIDS epidemic we must redouble our efforts to provide dermatology education to care providers in Africa. We review the burden of skin disease in Africa, how it relates to HIV/AIDS and global infectious disease, current educational strategies in Africa to address this need, and suggest potential solutions to move these efforts forward.

Acquired immunodeficiency syndrome (AIDS) of humans is caused by two lentiviruses, human immunodeficiency viruses types 1 and 2 (HIV-1 and HIV-2). Here, we describe the origins and evolution of these viruses, and the circumstances that led to the AIDS pandemic. Both HIVs are the result of multiple cross-species transmissions of simian immunodeficiency viruses (SIVs) naturally infecting African primates. Most of these transfers resulted in viruses that spread in humans to only a limited extent. However, one transmission event, involving SIVcpz from chimpanzees in southeastern Cameroon, gave rise to HIV-1 group M-the principal cause of the AIDS pandemic. We discuss how host restriction factors have shaped the emergence of new SIV zoonoses by imposing adaptive hurdles to cross-species transmission and/or secondary spread. We also show that AIDS has likely afflicted chimpanzees long before the emergence of HIV. Tracing the genetic changes that occurred as SIVs crossed from monkeys to apes and from apes to humans provides a new framework to examine the requirements of successful host switches and to gauge future zoonotic risk.

Much of Africa has been ravaged by the AIDS epidemic. There, heterosexual contact is the primary mode of transmission for the HIV virus. Even when access to condoms is good and their price low, a large fraction of young Africans continue to engage in unprotected sex. In this paper, we propose a simple two period rational model of sexual behavior that has the potential to explain why a large proportion of sexual activity in poor countries maybe unprotected.

As the number of HIV infected patients is multiplying exponentially day by day so are the associated ocular complications.The increasing longevity of individuals with HIV disease has resulted in greater numbers of pa-tients with ocular opportunistic infection.By the means of this article we describe various opportunistic ocular infections in AIDS and their clinical manifestations,discussed under four headings;1 )adnexal manifestation;2)anterior segment manifestation;3)posterior segment manifestation;4)neuro ophthalmic manifestation . Herpes zoster ophthalmicus,molluscum contagiosum and Kaposi sarcoma are common adnexal manifestations. Molluscum contagiosum being the commonest.Varicella Zoster Virus (VZV)and herpes simplex virus (HSV) most commonly cause infectious keratitis in HIV-positive patients .As compared to the immunocompetent indi-viduals the frequency of bacterial and fungal keratitis is not more in HIV patients,but it tends to be more se-vere.Posterior segment structures involved in HIV-positive patients include the retina,choroid,and optic nerve head.The herpesvirus family is implicated most commonly in infections of the retina and choroid in HIV positive patients.CMV is the most common cause of retinitis and the commonest intraocular infection in AIDS. Atypical presentations resistance to conventional treatment and higher rate of recurrence make the diagnosis and therapeutic intervention more difficult and challenging.In addition,in one eye,several infections may occur at the same time,rendering the situation more difficult.
Foreign aid is given for many purposes and different intentions, yet most studies treat aid flows as a unitary concept. This paper uses factor analysis to separate aid flows into different types. The main types can be interpreted as aid for economic purposes, social purposes, and reconstruction; a...... residual category captures remaining purposes. Estimating the growth effects of separable types of aid suggests that most aid has no effects while reconstruction aid has direct positive effects. Although this type only applies in special circumstances, it has become more prevalent in more recent years....

Since the first acquired immunodeficiency syndrome (AIDS) case was confirmed in 1986, Senegal has conducted an aggressive prevention campaign. Senegal's National AIDS Committee has noted the contributions of poverty and migration to the spread of AIDS. By June 1994, 1297 AIDS cases had been reported and an estimated 500,000 people (1.4% of the population) were infected with human immunodeficiency virus (HIV)-1 and 2. The highest rate of HIV infection (14%) exists among commercial sex workers. At present, HIV/AIDS cases are concentrated in Dakar, Kaolack, the Matam region, and Ziguinchor; however, the growing importance of inter-regional trading is expected to spread HIV to the smaller towns and rural areas. Also salient is the recent devaluation by 50% of the CFA franc, which has reduced the public sector workforce and led many poor urban residents into commercial sex work. CFA devaluation has made Senegal attractive to tourists and business visitors--another factor responsible for growth of the legalized commercial sex industry. Although sex workers are instructed in condom use and tested annually for HIV, only 850 of the 2000 registered sex workers have reported for check-ups, and the majority of prostitutes are unregistered. Senegal's AIDS Plan for 1994-98 focuses on care of AIDS patients, pressures placed on family structures by HIV, and AIDS-related erosions in the status of women. Each health service region has its own local plan for AIDS/HIV and sexually transmitted diseases, supervised by a regional committee. Public education has involved outreach to religious leaders, promotion of affordable condoms, and distribution of over 75,000 leaflets to key target populations. About US $16 million of the $25,688,875-budget HIV/AIDS program for 1994-98 was pledged by external donors. PMID:12320531

AIDS has a devastating impact on individuals and society. It is defined as Acquired Immune Deficiency Syndrome and it is a condition caused by the Human Immunodeficiency Virus (HIV). This condition occurs when people who have lived with HIV for a long time lose their immunity and become susceptible to various opportunistic infections. AIDS often results in death. At present, there is neither a vaccine against HIV nor a cure for AIDS. Apart from the numerous deaths it causes, HIV/AIDS has othe...
In this article, I address the lack of research in current scholarship on the impacts China’s changing media is having on those who consume messages about HIV and AIDS, and on the political, social, celebrity and corporate activism which have resulted from the improved circulation of knowledge...... about the virus in society.

I...... first discuss the fragmented history of the virus in telling AIDS in China.

The major cause of acquired immune deficiency syndrome (AIDS) is human immunodeficiency virus type 1 (HIV-1). We have been using evolutionary comparisons to trace (i) the origin(s) of HIV-1 and (ii) the origin(s) of AIDS. The closest relatives of HIV-1 are simian immunodeficiency viruses (SIVs) infecting wild-living chimpanzees (Pan troglodytes troglodytes) and gorillas (Gorilla gorilla gorilla) in west central Africa. Phylogenetic analyses have revealed the origins of HIV-1: chimpanzees were the original hosts of this clade of viruses; four lineages of HIV-1 have arisen by independent cross-species transmissions to humans and one or two of those transmissions may have been via gorillas. However, SIVs are primarily monkey viruses: more than 40 species of African monkeys are infected with their own, species-specific, SIV and in at least some host species, the infection seems non-pathogenic. Chimpanzees acquired from monkeys two distinct forms of SIVs that recombined to produce a virus with a unique genome structure. We have found that SIV infection causes CD4(+) T-cell depletion and increases mortality in wild chimpanzees, and so the origin of AIDS is more ancient than the origin of HIV-1. Tracing the genetic changes that occurred as monkey viruses adapted to infect first chimpanzees and then humans may provide insights into the causes of the pathogenicity of these viruses.

Acquired immune deficiency syndrome (AIDS) has been an African and Western concern due to its epidemic nature. Although nearly 99% of all reported cases occurred in these regions, Asia has reported cases, and the potential for devastation of Asia's already strained health care reserves are undeniable. This review compiled by analysis of 1986-88 articles on AIDS research, demographics, official statements from government and health organizations, news reports, and public statements describe how AIDS has spread in well documented regions like America, Europe, and Africa, and how the Asian regions have attempted to handle the AIDS epidemic before it becomes as serious as in the West. The topics covered include a clinical overview of how human immunodeficiency virus (HIV) causes AIDS, how it is transmitted, and what are the primary forms of transmission in well documented regions. The report briefly documents what policies China, Hong Kong, Japan, Republic of Korea, Taiwan, Philippines, Thailand, Singapore, Malaysia, Indonesia, India, Sri Lanka, Bangladesh, Nepal, Pakistan, Australia, and New Zealand have individually instituted to stem the flow of AIDS into their country, and/or stop the spread of AIDS already found there. The efforts to combat AIDS globally by the World Health Organization/United Nations Development Program alliance (WHO-UNDP) along with the US Agency for International Development (USAID), and UNICEF are highlighted. The available research and aid programs are contrasted with how the Asian nations are preparing to deal with the AIDS epidemic. 1) AIDS has an incubation time wherein an infected individual is not AIDS symptomatic, but is capable of infecting others, and this hidden infected population makes it essential that containment policies are also enforced in countries with few reported cases. 2) A committee should be established in all Asian countries to coordinate education on safe sexual behaviors with specific programs for prostitutes

A self-administered anonymous questionnaire on knowledge about acquired immunodeficiency syndrome (AIDS) was administered to 2,614 Leaving Certificate students in 50 Galway second-level schools. Levels of knowledge regarding routes of human immunodeficiency virus (HIV) transmission and non-transmission were assessed together with student opinion on related lifestyle issues and awareness of local services. Although 91% had heard of HIV infection only 61% knew that there is a difference between this and AIDS. Over 95% of respondants were aware of the epidemiologically proven means of transmission and between 73% and 98% understood that no transmission risk existed in a range of ordinary social contact situations. Fifty-one per cent of students believed in a HIV transmission risk from receiving blood transfusions in Ireland and 24% doubted the safety of blood donation. Seventy-four per cent of students indicated the media as their main information source on AIDS. Preference for further AIDS information were Health Education sources (30%) and teachers (20%). Only 22% and 23% of respondants respectively were aware of the local Sexually Transmitted Diseases Clinic and AIDS telephone information service. These data indicate areas in which information on AIDS should be improved by education in the school setting. PMID:2361831

Full Text Available The impact of gender on HIV/AIDS is an important dimension in understanding the evolution of the epidemic. HIV/AIDS is one of the vital problems of our century. HIV/AIDS is not merely a medical disease but also is a problem, which possesses economical, cultural, psychological and social dimensions. Women are more vulnerable to HIV than men because of biological and cultural factors. Besides women who carry HIV virus experience difficulty in taking care of their own health, they also carry the burden of possibility that their children and other members of the family might catch HIV virus. Most often, social support is insufficient and the conditions brought by treatment cannot be utilized appropriately due to external interventions. Most of the problems that women under the risk of HIV run into are largely social rather than medical. Many women infected with HIV were isolated because they didn’t get of sufficient social support or didn’t equal time for their care and it is thought that this inequality still continues. An analysis of the impact of gender on HIV/AIDS demonstrates the importance of integrating gender into HIV programming and finding ways to strengthen women by implementing policies and programs that increase their access to education and information. Women's empowerment is vital to reversing the epidemic.

The existing research on foreign aid offers inconclusive evidence on the factors that make aid effective. In this paper, we study the supply of aid money in 112 developing countries over the period 1960-1999 and find that the presence of multiple donors in a given country renders aid less effective. In particular, an aid-receiving country at the median of the donor fractionalization distribution will grow one percentage point faster than a country at the 75th percentile. This is in part becau...

Whether conveyed in a written or oral form, the messages of prevention are essentially verbal.

Full Text Available The main point of this paper is that foreign aid fails because the structure of its incentives resembles that of central planning. Aid is not only ineffective, it is arguably counterproductive. Contrary to business firms that are paid by those they are supposed to serve (customers, aid agencies are paid by tax payers of developed countries and not by those they serve. This inverse structure of incentives breaks the stream of pressure that exists on the commercial market. It also creates larger loopholes in the principle-agent relationship on each point along the chain of aid delivery. Both factors enhance corruption, moral hazard and negative selection. Instead of promoting development, aid extends the life of bad institutions and those in power. Proposals to reform foreign aid – like aid privatization and aid conditionality – do not change the existing structure of the incentives in aid delivery, and their implementation may just slightly improve aid efficacy. Larger improvement is not possible. For that reason, foreign aid will continue to be a waste of resources, probably serving some objectives different to those that are usually mentioned, like recipient’s development poverty reduction and pain relief.

The AEL (aid effectiveness literature) studies the effect of development aid using econometrics on macro data. It contains about 100 papers of which a third analyzes conditional models where aid effectiveness depends upon z, so that aid only works for a certain range of the variable. The key term...... in this family of AEL models is thus an interaction term of z times aid. The leading candidates for z are a good policy index and aid itself.

CHINA's first HIV positive diagnosis was in 1985, the victim an ArgentineAmerican. At that time most Chinese,medical workers included, thought of AIDS as a phenomenon occurring outside of China. Twenty years later, the number of HIV/AIDS patients has risen alarmingly. In 2003, the Chinese Ministry of Health launched an AIDS Epidemiological Investigation across China with the support of the WHO and UN AIDS Program. Its results show that there are currently 840,000 HIV carriers, including 80,000 people with full-blown AIDS, in 31 Chinese provinces, municipalities and autonomous regions. This means China has the second highest number of HIV/AIDS cases in Asia and 14th highest in the world. Statistics from the Chinese Venereal Disease and AIDS Prevention Association indicate that the majority of Chinese HIV carriers are young to middle aged, more than half of them between the ages of 20 and 29.

The human immunodeficiency virus (HIV) is a neurotropic virus. It induces neurotoxicity and subsequent brain pathologies in different brain cells. Addiction to recreational drugs remarkably affects the initiation of HIV infections and expedites the progression of acquired immunodeficiency syndrome (AIDS) associated neuropathogenesis. Symptoms of HIV-associated neurocognitive disorders (HAND) are noticed in many AIDS patients. At least 50 % of HIV diagnosed cases show one or other kind of neur...
ABSTRACTOver 29 years into the epidemic, fighting HIV (Human Immunodeficiency Virus), the virus that causes AIDS (Acquired, Immune, Deficiency, Syndrome) continues to be a global concern. School-based computer-assisted HIV/AIDS interventions can provide innovative ways of preventing HIV among young people from diverse backgrounds in Africa. However, questions of technological, social and organisational readiness cannot be overlooked. This is because of: (1) being health interventions implemen...
Urgent action is needed to fight the alarming spread of HIV/AIDS that infected 1.3 million people in Southeast Asia last year alone, Malaysia's foreign minister said July 24, 2000. Syed Hamid said the Association of Southeast Asian Nations (ASEAN) should tackle at regional and national level an epidemic that was taking its most drastic toll among the region's youth. "HIV/AIDS not only represents a major public health and social problem but is a serious challenge to development as well," Syed Hamid told the opening ceremony of ASEAN's 33rd annual foreign ministers' meeting. The crisis requires commitment at the "highest political level," he said, warning that HIV/AIDS could become a transnational problem within the 10-member group. Foreign ministers have recommended their leaders discuss the crisis later this year at an informal summit in Singapore and hold a summit on HIV/AIDS in conjunction with the 7th ASEAN Summit in Brunei next year. "I think people recognized the importance and the adverse impacts on our social development," Syed Hamid told reporters later. "I think it is a real issue that we cannot run away from." Among ASEAN members, Thailand, Cambodia, and Myanmar have some of the highest infection rates in Asia of HIV, the virus that causes AIDS. PMID:12349742

The signal processing and fitting methods used for hearing aids have mainly been designed to optimize the intelligibility of speech. Little attention has been paid to the effectiveness of hearing aids for listening to music. Perhaps as a consequence, many hearing-aid users complain that they are not satisfied with their hearing aids when listening to music. This issue inspired the Internet-based survey presented here. The survey was designed to identify the nature and prevalence of problems associated with listening to live and reproduced music with hearing aids. Responses from 523 hearing-aid users to 21 multiple-choice questions are presented and analyzed, and the relationships between responses to questions regarding music and questions concerned with information about the respondents, their hearing aids, and their hearing loss are described. Large proportions of the respondents reported that they found their hearing aids to be helpful for listening to both live and reproduced music, although less so for the former. The survey also identified problems such as distortion, acoustic feedback, insufficient or excessive gain, unbalanced frequency response, and reduced tone quality. The results indicate that the enjoyment of listening to music with hearing aids could be improved by an increase of the input and output dynamic range, extension of the low-frequency response, and improvement of feedback cancellation and automatic gain control systems.

We analysed cumulative disease frequencies in the first 231 adult Danish AIDS patients with life tables. There was a certain hierarchical pattern in the occurrence of complicating diseases. Herpes zoster, Kaposi's sarcoma and Pneumocystis carinii pneumonia were early manifestations, whereas...... diseases caused by cytomegalovirus and atypical mycobacteria tended to occur later in the course of AIDS. Compared with all other AIDS patients, homosexual men were more likely to develop Kaposi's sarcoma, cytomegalovirus chorioretinitis and mucocutaneous herpes simplex virus infection. The proportion of...... patients who developed particular diseases changed with calendar time. Most striking was a three to fourfold decrease in diseases caused by cytomegalovirus. In conclusion, the study showed that disease frequencies in patients with AIDS may vary with the patients risk behaviour and duration of AIDS, and...

The current Zika virus (ZIKV) epidemic in the Americas caused an increase in diagnostic requests in European countries. Here we demonstrate high specificity of the Euroimmun anti-ZIKV IgG and IgM ELISA tests using putative cross-reacting sera of European patients with antibodies against tick-borne encephalitis virus, dengue virus, yellow fever virus and hepatitis C virus. This test may aid in counselling European travellers returning from regions where ZIKV is endemic. PMID:27126052

If your company operates in a developing country, AIDS is your business. While Africa has received the most attention, AIDS is also spreading swiftly in other parts of the world. Russia and Ukraine had the fastest-growing epidemics last year, and many experts believe China and India will suffer the next tidal wave of infection. Why should executives be concerned about AIDS? Because it is destroying the twin rationales of globalization strategy-cheap labor and fast-growing markets--in countries where people are heavily affected by the epidemic. Fortunately, investments in programs that prevent infection and provide treatment for employees who have HIV/AIDS are profitable for many businesses--that is, they lead to savings that outweigh the programs' costs. Due to the long latency period between HIV infection and the onset of AIDS symptoms, a company is not likely to see any of the costs of HIV/AIDS until five to ten years after an employee is infected. But executives can calculate the present value of epidemic-related costs by using the discount rate to weigh each cost according to its expected timing. That allows companies to think about expenses on HIV/AIDS prevention and treatment programs as investments rather than merely as costs. The authors found that the annual cost of AIDS to six corporations in South Africa and Botswana ranged from 0.4% to 5.9% of the wage bill. All six companies would have earned positive returns on their investments if they had provided employees with free treatment for HIV/AIDS in the form of highly active antiretroviral therapy (HAART), according to the mathematical model the authors used. The annual reduction in the AIDS "tax" would have been as much as 40.4%. The authors' conclusion? Fighting AIDS not only helps those infected; it also makes good business sense. PMID:12577655

Human immunodeficiency virus (HIV) is a neurotropic virus that enters the central nervous system (CNS) early in the course of infection. Although highly active antiretroviral therapy (HAART) has resulted in remarkable decline in the morbidity and mortality in AIDS patients, controlling HIV infections still remains a global health priority. HIV access to the CNS serves as the natural viral preserve because most antiretroviral (ARV) drugs possess inadequate or zero delivery across the brain barriers. The structure of the blood-brain barrier (BBB), the presence of efflux pumps, and the expression of metabolic enzymes pose hurdles for ARV drug-brain entry. Thus, development of target-specific, effective, safe, and controllable drug delivery approach is an important health priority for global elimination of AIDS progression. Nanoformulations can circumvent the BBB to improve CNS-directed drug delivery by affecting such pumps and enzymes. Alternatively, they can be optimized to affect their size, shape, and protein and lipid coatings to facilitate drug uptake, release, and ingress across the barrier. Improved drug delivery to the CNS would affect pharmacokinetic and drug biodistribution properties. This review focuses on how nanotechnology can serve to improve the delivery of antiretroviral medicines, termed NanoART, across the BBB and affect the biodistribution and clinical benefit for NeuroAIDS.

Editors' Summary Background. Acquired immunodeficiency syndrome (AIDS) has killed 29 million people since the first case occurred in 1981 and an estimated 40 million people live with HIV/AIDS today. AIDS is caused by the human immunodeficiency virus (HIV), which destroys the immune system. Infected individuals are consequently very susceptible to other infections. Early in the AIDS epidemic, most HIV-positive individuals died within a few years of becoming infected. Then, in 1996, highly acti...

Full Text Available The world has been challenged by the AIDS epidemic for 15 years. In 1985, the U.S. Department of Health and Human Services, Centers for Disease Control, allocated funds to all state departments of education to assist schools in the development of AIDS education policies and programs. Yet, these policies do not ensure that all students receive effective AIDS education. On September 21, 1991, the Arizona Legislature passed Senate Bill 1396, which requires public schools to annually provide AIDS education in grades K-12. The bill was rescinded in 1995. With prohibitive curriculum guidelines, limited teacher training opportunities and tremendous instructional demands, this educational policy was implemented in disparate forms. By examining the perspectives of the Arizona educators (representing three school districts, this qualitative study reveals how teachers ultimately controlled the delivery and nature of AIDS instruction based upon personal values, views of teacher roles, and their interpretation of the mandate itself.

@@ The human immunodeficiency virus type 1 (HIV-1) causes an acquired immunodeficiency syndrome (AIDS).HIV-1 infects human immune cells,specifically CD4+ lymphocytes, which leads to AIDS and undermines reconstitution of immunity. The unique challenges of HIV/AIDS have triggered multidisciplinary investigators to study the virology of the pathogen and the biology of the host cells, especially the interactions of HIV-1 with T-lymphocytes,macrophages, and hematopoietic stem and progenitor cells (HSPC) [1-8].

Full Text Available Objectives: To describe information about HIV/AIDS in a youth population under 18 years of age affected with HIV/AIDS and caregivers in five Colombian cities: Cali, Buenaventura, Barranquilla, Santa Marta, and Cartagena. Methods: 286 personal surveys were conducted: 11 of children who were aware of their status of involvement with HIV/AIDS and 275 of caregivers of children who did not know their status of involvement with HIV/AIDS. The surveys were conducted in health institutions in the State and private sectors and private, using instruments in line with training programs from participating institutions to inquire about HIV/AIDS. Descriptive analysis was performed of the data and tabulation was done with the SPSS program. Results: Most children who knew their status of involvement with HIV/AIDS report that by acquiring the HIV virus, they may develop other diseases; however, half of these fail to recognize that AIDS weakens the body’s ability to fight infection. The children surveyed partly recognized the HIV/AIDS transmission and treatment mechanisms, while caregivers possess adequate information on the disease. We found reasons to delay the delivery of diagnosis by caregivers 96.2% (N=275 related to avoiding psychological harm to the children, and that if they were to know said status, they might inadvertently disclose this to others, probably exposing them to stigma and/or discrimination. Likewise, professionals providing health services to HIV seropositive children express lack of training regarding the proper procedure and age to reveal such information. Conclusions: It is a priority to enhance the capacity, information, and education of patients about effects, characteristics, manifestations, and treatment of the disease within the comprehensive health management processes conducive to supporting affected families.

In dealing with HIV infection and AIDS, the law must balance the public health interests of the community against the potentially conflicting rights of individuals to liberty and privacy. This article reviews public health legislation currently in force in Australian States and Territories, discusses the potential for coercive strategies to be applied to AIDS sufferers and persons who are or who are presumed to be infected with HIV, and considers how to deal with HIV-infected persons who knowingly or recklessly spread the virus. It is possible that strong measures to control the spread of HIV may be counterproductive because they discourage the cooperation of infected persons and groups at high risk of infection. Although the potential for restrictive practices is great, the law must make, and in Australia has made, some compromises in the interests of the individual and the larger community. PMID:1984590

Fifty-two patients with pulmonary complications of acquired immunodeficiency syndrome (AIDS) were studied over a 3-year period. The vast majority of the patients were homosexual; however, a significant number were intravenous drug abusers. Thirteen different organisms were noted, of which Pneumocystis carinii was by far the most common. Five patients had neoplasia. Most patients had initial abnormal chest films; however, eight patients subsequently shown to have Pneumocystis carinii pneumonia had normal chest films. A significant overlap in chest radiographic findings was noted among patients with different or multiple organisms. Lung biopsy should be an early consideration for all patients with a clinical history consistent with the pulmonary complications of AIDS. Of the 52 patients, 41 had died by the time this report was completed.

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. Women now make up half of all people living with HIV worldwide with the number of 17,6 million. [TAF Prev Med Bull 2004; 3(11.000: 280-290

The current outbreak of Zika virus is a growing public health concern, especially for pregnant women. Zika virus infection may manifest as a maculopapular skin eruption that progresses rostrocaudally, with or without hemorrhagic manifestations such as petechiae and gingival bleeding. Recognizing the cutaneous findings associated with Zika virus may aid in early diagnosis, particularly in individuals at increased risk for the disease.
