    Full Text Available A 37-year-old man with a three-year history of Acquired Immunodeficiency Syndrome was admitted with impaired consciousness, seizures and fever. He was on highly active antiretroviral therapy and on neurotoxoplasmosis secondary prophylaxis. Laboratory exams from two months before showed a CD4 cell count of 37/µL and a viral load of 230,000 copies/mL. Three months before admission he developed herpetic skin rash in the right trunk and acyclovir was added to his treatment regimen. On physical exam he was drowsy and had motor and sensory aphasia. The patient had elevated protein levels and normal pressure in the cerebrospinal fluid (CSF. Contrast enhanced computed tomography scan of the brain showed a hypodense lesion in the left parietal lobe, with poorly defined margins and no contrast enhancement. The magnetic resonance scan (MRI showed multiple hyperintensities in T2-weighted image in white and grey matters and hypointense products of hemorrhage in both hemispheres and in the cerebellum. He was empirically treated with intravenous acyclovir and prednisone. Viral DNA of Varicella-zoster virus (VZV was detected in the CSF by means of polymerase chain reaction (PCR analysis. Acyclovir was continued for 10 days and the patient became well, with improvement of aphasia.We present a case of VZV encephalitis, confirmed by nested PCR, in a patient with suggestive MRI findings, who succeeded with treatment. VZV encephalitis is a rare opportunistic infection, occurring in 0.1 to 4% of AIDS patients with neurological disease; it is related to severe immunodeficiency and has a high mortality.

    Full Text Available Abstract Tumor viruses are linked to approximately 20% of human malignancies worldwide. This review focuses on examples of human oncogenic viruses that manipulate the ubiquitin system in a subset of viral malignancies; those associated with AIDS. The viruses include Kaposi's sarcoma herpesvirus, Epstein-Barr virus and human papilloma virus, which are causally linked to Kaposi's sarcoma, certain B-cell lymphomas and cervical cancer, respectively. We discuss the molecular mechanisms by which these viruses subvert the ubiquitin system and potential viral targets for anti-cancer therapy from the perspective of this system.

    Heat treatment at 60 degrees C for 10 h in solution (pasteurization) was introduced into the manufacturing process of antihemophilic cryoprecipitate (AHC) and factor VIII concentrates (F VIII) to reduce the risk of transmission of hepatitis to hemophiliacs. Since the acquired immunodeficiency syndrome (AIDS) may also be transmitted to hemophiliacs by antihemophilic plasma protein preparations, we have investigated inactivation of the AIDS virus HTLV III by pasteurization in AHC or F VIII and included in this study cytomegalovirus (CMV), Epstein-Barr virus (EBV), herpes simplex virus (HSV), poliovirus and vaccinia virus. Each of these viruses was efficiently inactivated by pasteurization although considerable differences were observed between the different viruses HTLV III was rapidly inactivated, becoming nondetectable within 30-60 min. Our findings indicate that pasteurized AHC or F VIII should have a high margin of safety regarding the transmission of AIDS or any other infectious disease caused by viruses such as those tested.

  6. A mathematical model of the spread of the AIDS virus

    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.

    2002-01-01

    Human herpesvirus oesophagitis in human immunodeficiency virus positive patients is caused by cytomegalovirus and herpes simplex virus; no cases of oesophagitis and oesophagobrochial fistula as a result of varicella zoster virus (VZV) have been reported to date. This report describes the case of a patient with a 2–3 mm deep oesophageal ulcer whose viral culture was positive for VZV. The patient was treated with acyclovir with resolution of the symptomatology. After the end of the induction treatment, because of the onset of fever and fits of coughing during eating, the patient underwent oesophagography, which showed an ulcer with an oesophagobronchial fistula in the middle and lower third of the oesophagus. This case report stresses the role of VZV infection as a possible cause of oesophagobronchial fistula, a rare but benign condition in patients with AIDS. PMID:11986352

    Full Text Available Background: human immunodeficiency virus increases patients´ susceptibility to infections. Consequently, a high incidence of periodontal diseases is observed among them. It is often associated with other lesions of the oral mucous. Objective: to determine the evolution of chronic inflammatory periodontal disease in patients diagnosed with human immunodeficiency virus/AIDS.Methods: a case series study involving HIV-positive patients who attended the Stomatology consultation in Cienfuegos was conducted. The Russell Periodontal Index and the Simplified Oral Hygiene Index were used. Patients were classified taking into account clinical and immunological categories. Statistical processing was performed through SPSS program version 15.0 and Chi-square tests were applied.Results: a high prevalence of chronic inflammatory periodontal disease was observed in patients with human immunodeficiency virus. Correlation with the oral hygiene of the patients studied was found. CD4 count showed no statistical significance in periodontal disease severity. All patients classified as A2 suffer from some stage of periodontal disease, which was the most affected clinical category in spite of presenting mild immunodeficiency.Conclusions: there is a high prevalence of chronic inflammatory periodontal disease in patients diagnosed with Human Immunodeficiency Virus in Cienfuegos and it is correlated with patient’s oral hygiene.

  15. Productive human immunodeficiency virus infection levels correlate with AIDS-related manifestations in the patient

    International Nuclear Information System (INIS)

    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

    CD4(+) T follicular helper (Tfh) cells are critical for the generation of humoral immune responses to pathogenic infections, providing help for B cell development, survival, and affinity maturation of Abs. Although CD4(+) Tfh cells are reported to accumulate in HIV or SIV infection, we found that germinal center Tfh cells, defined in this study as CXCR5(+)PD-1(HIGH)CD4(+) T cells, did not consistently accumulate in chronically SIV-infected rhesus macaques compared with those infected with less pathogenic simian HIV, vaccinated and SIVmac-challenged, or SIVmac-infected Mamu-A*01(+) macaques, all of which are associated with some control of virus replication and slower disease progression. Interestingly, CXCR5(+)PD-1(HIGH) Tfh cells in lymphoid tissues were eventually depleted in macaques with AIDS compared with the other cohorts. Chronic activation and proliferation of CXCR5(+)PD-1(HIGH) Tfh were increased, but PD-L2 expression was downregulated on B cells, possibly resulting in germinal center Tfh cell apoptosis. Together, these findings suggest that changes in CXCR5(+)PD-1(HIGH) Tfh cells in lymph nodes correlate with immune control during infection, and their loss or dysregulation contribute to impairment of B cell responses and progression to AIDS.

    The CTL response to HIV was analyzed in humans and in mice. By using a novel and strictly autologous lymphocyte culture system, human CTL lines were established with PBL from seropositive asymptomatic donors and from patients suffering from AIDS or presenting AIDS-related complex. CTL from HLA-A2 donors recognize and kill murine P815 mastocytoma cells doubly transfected with the human HLA-A2 gene and the HIV env gene; they also kill HLA-compatible human macrophages infected with HIV. CTL specific for the HIV env Ag were also generated in BALB/c mice by immunization with syngeneic murine cells transfected with the HIV env gene. Human and murine HIV-immune CTL populations belong to the CD8 subset of T lymphocytes and are restricted by class I HLA or H-2 transplantation Ag, respectively, in the recognition of HIV env Ag. The two different experimental systems presented here can be used to study CD8 lymphocyte immunity against HIV. The murine model of CTL immunity offers the additional advantage of avoiding the manipulation of infectious virus isolates.

  2. Newcastle disease virus passage in MDBK cells as an aid in detection of a virulent subpopulation.

    1993-01-01

    Newcastle disease virus strains (NDV) La Sota, Texas GB (GB), and mixtures of the two strains were serially passaged in embryonated chicken eggs or the MDBK cell line, a more restrictive culture system than eggs for NDV. The two culture systems were compared by evaluating culture harvests for pathogenicity in inoculated chickens; the harvests were identified by hemagglutination-inhibition tests against monoclonal antibodies that can differentiate La Sota and GB cultures. Both viruses, inoculated alone or as mixtures, were propagated by passage in chicken eggs. La Sota strain failed to propagate by continuous passage in MDBK cells, and only GB was identified in culture harvests propagated in MDBK cells that had been inoculated with GB or mixtures of GB and La Sota. The results indicate that the MDBK cell line is a more selective substrate than chicken eggs and suggest that passage in MDBK cells may aid in selecting for more virulent subpopulations of NDV in a mixed culture. Other reference NDV strains, pigeon NDV isolates, and recent lentogenic NDV isolates from chickens were also passaged in MDBK cells; all strains except those that are classified as lentogens like La Sota could be serially propagated in MDBK cells.

    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.

    Enveloped viruses are viewed as an opportunity to understand how highly organized and functional biosystems can emerge from a collection of millions of chaotically moving atoms. They are an intermediate level of complexity between macromolecules and bacteria. They are a natural system for testing theories of self-assembly and structural transitions, and for demonstrating the derivation of principles of microbiology from laws of molecular physics. As some constitute threats to human health, a computer-aided vaccine and drug design strategy that would follow from a quantitative model would be an important contribution. However, current molecular dynamics simulation approaches are not practical for modeling such systems. Our multiscale approach simultaneously accounts for the outer protein net and inner protein/genomic core, and their less structured membranous material and host fluid. It follows from a rigorous multiscale deductive analysis of laws of molecular physics. Two types of order parameters are introduced: (1) those for structures wherein constituent molecules retain long-lived connectivity (they specify the nanoscale structure as a deformation from a reference configuration) and (2) those for which there is no connectivity but organization is maintained on the average (they are field variables such as mass density or measures of preferred orientation). Rigorous multiscale techniques are used to derive equations for the order parameters dynamics. The equations account for thermal-average forces, diffusion coefficients, and effects of random forces. Statistical properties of the atomic-scale fluctuations and the order parameters are co-evolved. By combining rigorous multiscale techniques and modern supercomputing, systems of extreme complexity can be modeled.

    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.

    Full Text Available Neurological complications of varicella-zoster virus (VZV are infrequent and include various clinical pictures. The reactivation of VZV in patients with AIDS is generally associated with an acute and severe meningoencephalitis. We report the epidemiological, clinical and virological data from 11 consecutive patients with diagnosis of HIV/AIDS and central nervous system (CNS involvement due to VZV. All patients were male and seropositive for HIV. The primary risk factor for HIV infection was unprotected sexual contact. The median of CD4 T cell count was 142 cells/µL. All of them presented signs and symptoms of meningoencephalitis. Six patients (54.5% presented pleocytosis; they all showed high CSF protein concentrations with a median of 2.1 g/dL. Polymerase chain reaction of cerebrospinal fluid specimen was positive for VZV in all of them and they were treated with intravenous acyclovir at doses of 30/mg/kg/day for 21 days. Overall survival was 63% (7 of 11 patients. The four dead patients had low cellular counts in CSF, below the median of this parameter. VZV should be included among the opportunistic pathogens that can involve CNS with a diffuse and severe meningoencephalitis in patients with advanced HIV/AIDS disease.

  16. A novel role for APOBEC3: Susceptibility to sexual transmission of murine acquired immunodeficiency virus (mAIDS is aggravated in APOBEC3 deficient mice

    2012-06-01

    Full Text Available Abstract Background APOBEC3 proteins are host factors that restrict infection by retroviruses like HIV, MMTV, and MLV and are variably expressed in hematopoietic and non-hematopoietic cells, such as macrophages, lymphocytes, dendritic, and epithelia cells. Previously, we showed that APOBEC3 expressed in mammary epithelia cells function to limit milk-borne transmission of the beta-retrovirus, mouse mammary tumor virus. In this present study, we used APOBEC3 knockout mice and their wild type counterpart to query the role of APOBEC3 in sexual transmission of LP-BM5 MLV – the etiological agent of murine AIDs (mAIDs. Results We show that mouse APOBEC3 is expressed in murine genital tract tissues and gametes and that genital tract tissue of APOBEC3-deficient mice are more susceptible to infection by LP-BM5 virus. APOBEC3 expressed in genital tract tissues most likely plays a role in decreasing virus transmission via the sexual route, since mice deficient in APOBEC3 gene have higher genitalia and seminal plasma virus load and sexually transmit the virus more efficiently to their partners compared to APOBEC3+ mice. Moreover, we show that female mice sexually infected with LP-BM5 virus transmit the virus to their off-spring in APOBEC3-dependent manner. Conclusion Our data indicate that genital tissue intrinsic APOBEC3 restricts genital tract infection and limits sexual transmission of LP-BM5 virus.

    Synthetic attenuated virus engineering (SAVE) is an emerging technology that enables rapid attenuation of viruses. In this study, by using SAVE we demonstrated rapid attenuation of an arterivirus, porcine reproductive and respiratory syndrome virus (PRRSV). The major envelope GP5 gene of PRRSV was codon-pair deoptimized aided by a computer algorithm. The codon-pair deoptimized virus, designated as SAVE5 with a deoptimized GP5 gene, was successfully rescued in vitro. The SAVE5 virus replicated at a lower level in vitro with a significant decrease of GP5 protein expression compared to the wild-type PRRSV VR2385 virus. Pigs experimentally infected with the SAVE5 virus had significantly lower viremia level up to 14 days post-infection as well as significantly reduced gross and histological lung lesions when compared to wild-type PRRSV VR2385 virus-infected pigs, indicating the attenuation of the SAVE5 virus. This study proved the feasibility of rapidly attenuating PRRSV by SAVE.

    Exosomes are membranous extracellular nanovesicles secreted by diverse cell types. Exosomes from healthy human semen have been shown to inhibit HIV-1 replication and to impair progeny virus infectivity. In this study, we examined the ability of healthy human semen exosomes to restrict HIV-1 and LP-BM5 murine AIDS virus transmission in three different model systems. We show that vaginal cells internalize exosomes with concomitant transfer of functional mRNA. Semen exosomes blocked the spread of HIV-1 from vaginal epithelial cells to target cells in our cell-to-cell infection model and suppressed transmission of HIV-1 across the vaginal epithelial barrier in our trans-well model. Our in vivo model shows that human semen exosomes restrict intravaginal transmission and propagation of murine AIDS virus. Our study highlights an antiretroviral role for semen exosomes that may be harnessed for the development of novel therapeutic strategies to combat HIV-1 transmission.

  19. Rapid spread of tomato yellow leaf curl virus in China is aided differentially by two invasive whiteflies.

    Directory of Open Access Journals (Sweden)

    Huipeng Pan

    Full Text Available BACKGROUND: Tomato yellow leaf curl virus (TYLCV was introduced into China in 2006, approximately 10 years after the introduction of an invasive whitefly, Bemisia tabaci (Genn. B biotype. Even so the distribution and prevalence of TYLCV remained limited, and the economic damage was minimal. Following the introduction of Q biotype into China in 2003, the prevalence and spread of TYLCV started to accelerate. This has lead to the hypothesis that the two biotypes might not be equally competent vectors of TYLCV. METHODOLOGY/PRINCIPAL FINDINGS: The infection frequency of TYLCV in the field-collected B. tabaci populations was investigated, the acquisition and transmission capability of TYLCV by B and Q biotypes were compared under the laboratory conditions. Analysis of B. tabaci populations from 55 field sites revealed the existence of 12 B and 43 Q biotypes across 18 provinces in China. The acquisition and transmission experiments showed that both B and Q biotypes can acquire and transmit the virus, however, Q biotype demonstrated superior acquisition and transmission capability than its B counterparts. Specifically, Q biotype acquired significantly more viral DNA than the B biotype, and reached the maximum viral load in a substantially shorter period of time. Although TYLCV was shown to be transmitted horizontally by both biotypes, Q biotype exhibited significantly higher viral transmission frequency than B biotype. Vertical transmission result, on the other hand, indicated that TYLCV DNA can be detected in eggs and nymphs, but not in pupae and adults of the first generation progeny. CONCLUSIONS/SIGNIFICANCE: These combined results suggested that the epidemiology of TYLCV was aided differentially by the two invasive whiteflies (B and Q biotypes through horizontal but not vertical transmission of the virus. This is consistent with the concomitant eruption of TYLCV in tomato fields following the recent rapid invasion of Q biotype whitefly in China.

    1986-02-22

    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

    2012-06-01

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

    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

    Full Text Available Varicella-zoster virus (VZV meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR technique. The patient started undergoing an intravenous acyclovir therapy with a mild recovery of neurological manifestations. Varicella-zoster virus should be included as a cause of acute meningoencephalomyelitis in patients with AIDS. Early diagnosis followed by specific therapy should modify the rapid and fulminant course for this kind of patients.

    Bekelynck, A

    2015-02-01

    In the 1990s, defenders of "aids exceptionnalism" have promised that the inequities caused by HIV/AIDS could provide leverage in the care of other health issues later. Fifteen years later, this argument can be rethought at the light of the current context of hepatitis B virus (HBV) in Ivory Coast. In fact, in this country, the challenges caused by HBVecho those of HIV/AIDS fifteen years ago: high prevalence (8-10%), ignorance of the disease, and high cost of care. To this end, this article compares the role of private companies in the fights against HIV/AIDS in the 2000s and its role in the fight against HBV today. Although some private firms played a critical role in the promotion of universal access to ART, today, they are one of the few places where HBV screening, vaccination and treatment are offered in the country. HIV/AIDS opened the door for private companies to address other diseases through their health care systems. However, many challenges still need to be met: the absence of qualitative ongoing training for health professionals, illness representations and the costs of treatments, which are all related to the lack of international and national collective action. In Ivory Coast, at the early stage of the HIV/AIDS epidemic, national authorities took up the leadership in the fight against AIDS in West Africa, by developing extraverted strategies (Xth ICASA's organization, Unaids initiative hosting). The exceptional international mobilization and the creation of innovative funding mechanisms [International Therapeutic Solidarity Fund (ITSF), Global Fund (GM), and President's Emergency Plan for AIDS Relief (PEPFAR)] have facilitated easy access to ARV. Although 380 million people are infected by chronic HBV in the world, even so, international and national collective actions are fledgling and remained weak. Moreover, private firms have represented leverage for testing, treatment, and the provision of universal access to medication in the context of the HIV/AIDS

    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).

    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 order to assess the applicability of multiplexed fluorescence in situ hybridization (FISH) assay for the clinical setting, we conducted retrospective analysis of 110 formalin-stored diarrheic stool samples from human immunodeficiency virus (HIV)/AIDS patients with intestinal microsporidiosis collected between 1992 and 2003. The multiplexed FISH assay identified microsporidian spores in 94 of 110 (85.5%) samples: 49 (52.1%) were positive for Enterocytozoon bieneusi, 43 (45.8%) were positive for Encephalitozoon intestinalis, 2 (2.1%) were positive for Encephalitozoon hellem, and 9 samples (9.6%) contained both E. bieneusi and E. intestinalis spores. Quantitative spore counts per ml of stool yielded concentration values from 3.5 × 103 to 4.4 × 105 for E. bieneusi (mean, 8.8 × 104/ml), 2.3 × 102 to 7.8 × 104 (mean, 1.5 × 104/ml) for E. intestinalis, and 1.8 × 102 to 3.6 × 102 for E. hellem (mean, 2.7 × 102/ml). Identification of microsporidian spores by multiplex FISH assay was more sensitive than both Chromotrope-2R and CalcoFluor White M2R stains; 85.5% versus 72.7 and 70.9%, respectively. The study demonstrated that microsporidian coinfection in HIV/AIDS patients with intestinal microsporidiosis is not uncommon and that formalin-stored fecal samples older than 10 years may not be suitable for retrospective analysis by techniques targeting rRNA. Multiplexed FISH assay is a reliable, quantitative fluorescence microscopy method for the simultaneous identification of E. bieneusi, E. intestinalis, and E. hellem, as well as Encephalitozoon cuniculi, spores in fecal samples and is a useful tool for assessing spore shedding intensity in intestinal microsporidiosis. The method can be used for epidemiological investigations and applied in clinical settings. PMID:17287331

    Full Text Available BACKGROUND: Although Chinese-origin Rhesus macaques (Ch RhMs infected with simian immunodeficiency virus (SIV have been used for many years to evaluate the efficacy of AIDS vaccines and therapeutics, the bio-clinical variability of such a nonhuman primate AIDS model was so far not established. METHODOLOGY/PRINCIPAL FINDINGS: By randomizing 150 (78 male and 72 female Ch RhMs with diverse MHC class I alleles into 3 groups (50 animals per group challenged with intrarectal (i.r. SIVmac239, intravenous (i.v. SIVmac239, or i.v. SIVmac251, we evaluated variability in bio-clinical endpoints for 118 weeks. All SIV-challenged Ch RhMs became seropositive for SIV during 1-2 weeks. Plasma viral load (VL peaked at weeks 1-2 and then declined to set-point levels as from week 5. The set-point VL was 30 fold higher in SIVmac239 (i.r. or i.v.-infected than in SIVmac251 (i.v.-infected animals. This difference in plasma VL increased overtime (>100 fold as from week 68. The rates of progression to AIDS or death were more rapid in SIVmac239 (i.r. or i.v.-infected than in SIVmac251 (i.v.-infected animals. No significant difference in bio-clinical endpoints was observed in animals challenged with i.r. or i.v. SIVmac239. The variability (standard deviation in peak/set-point VL was nearly one-half lower in animals infected with SIVmac239 (i.r. or i.v. than in those infected with SIVmac251 (i.v., allowing that the same treatment-related difference can be detected with one-half fewer animals using SIVmac239 than using SIVmac251. CONCLUSION/SIGNIFICANCE: These results provide solid estimates of variability in bio-clinical endpoints needed when designing studies using the Ch RhM SIV model and contribute to the improving quality and standardization of preclinical studies.

    Full Text Available Abstract Background Women with severe maternal morbidity are at high risk of dying. Quality and prompt management and sometimes luck have been suggested to reduce on the risk of dying. The objective of the study was to identify the direct and indirect causes of severe maternal morbidity, predictors of progression from severe maternal morbidity to maternal mortality in Mulago hospital, Kampala, Uganda. Methods This was a longitudinal follow up study at the Mulago hospital's Department of Obstetrics and Gynaecology. Participants were 499 with severe maternal morbidity admitted in Mulago hospital between 15th November 2001 and 30th November 2002 were identified, recruited and followed up until discharge or death. Potential prognostic factors were HIV status and CD4 cell counts, socio demographic characteristics, medical and gynaecological history, past and present obstetric history and intra- partum and postnatal care. Results Severe pre eclampsia/eclampsia, obstructed labour and ruptured uterus, severe post partum haemorrhage, severe abruptio and placenta praevia, puerperal sepsis, post abortal sepsis and severe anaemia were the causes for the hospitalization of 499 mothers. The mortality incidence rate was 8% (n = 39, maternal mortality ratio of 7815/100,000 live births and the ratio of severe maternal morbidity to mortality was 12.8:1. The independent predictors of maternal mortality were HIV/AIDS (OR 5.1 95% CI 2-12.8, non attendance of antenatal care (OR 4.0, 95% CI 1.3-9.2, non use of oxytocics (OR 4.0, 95% CI 1.7-9.7, lack of essential drugs (OR 3.6, 95% CI 1.1-11.3 and non availability of blood for transfusion (OR 53.7, 95% CI (15.7-183.9 and delivery of amale baby (OR 4.0, 95% CI 1.6-10.1. Conclusion The predictors of progression from severe maternal morbidity to mortalitywere: residing far from hospital, low socio economic status, non attendance of antenatal care, poor intrapartum care, and HIV/AIDS.

    Full Text Available 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.

  6. CD8+ T lymphocytes of patients with AIDS maintain normal broad cytolytic function despite the loss of human immunodeficiency virus-specific cytotoxicity

    International Nuclear Information System (INIS)

    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

    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

    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

  15. Depo-provera treatment does not abrogate protection from intravenous SIV challenge in female macaques immunized with an attenuated AIDS virus.

    Directory of Open Access Journals (Sweden)

    Meritxell Genescà

    Full Text Available BACKGROUND: In a previous study, progesterone treatment of female monkeys immunized with live, attenuated SHIV89.6 abrogated the generally consistent protection from vaginal simian immunodeficiency virus (SIV challenge. The mechanisms responsible for the loss of protection remain to be defined. The objective of the present study was to determine whether Depo-Provera administration alters protection from intravenous SIV challenge in SHIV-immunized female macaques. METHODS AND FINDINGS: Two groups of female macaques were immunized with attenuated SHIV89.6 and then challenged intravenously with SIVmac239. Four weeks before challenge, one animal group was treated with Depo-Provera, a commonly used injectable contraceptive progestin. As expected, SHIV-immunized monkeys had significantly lower peak and set-point plasma viral RNA levels compared to naïve controls, but in contrast to previously published findings with vaginal SIV challenge, the Depo-Provera SHIV-immunized animals controlled SIV replication to a similar, or even slightly greater, degree than did the untreated SHIV-immunized animals. Control of viral replication from week 4 to week 20 after challenge was more consistent in the progesterone-treated, SHIV-immunized animals than in untreated, SHIV-immunized animals. Although levels of interferon-gamma production were similar, the SIV-specific CD8(+ T cells of progesterone-treated animals expressed more functions than the anti-viral CD8(+ T cells from untreated animals. CONCLUSIONS: Depo-Provera did not diminish the control of viral replication after intravenous SIV challenge in female macaques immunized with a live-attenuated lentivirus. This result contrasts with the previously reported effect of Depo-Provera(R on protection from vaginal SIV challenge and strongly implies that the decreased protection from vaginal challenge is due to effects of progesterone on the genital tract rather than to systemic effects.

    Tests to detect serum antibody to human T-lymphotropic virus type III (HTLV-III), based on an enzyme-linked immunosorbent assay (ELISA) that uses whole disrupted HTLV-III virus antigens, are now commercially available in the US. Recent surveys of groups at high risk for acquired immunodeficiency syndrome (AIDS) have found that 22-65% of homosexual men, 87% of active intravenous drug users, 56-72% of hemophiliacs, and 35% of women who were sexual partners of men with AIDS have had postitive ELISA tests compared with fewer than 1% of those with no known risk factors. A positive ELISA test could be due to subclinical infection, immunity, or cross-reactivity with other viral antigens. Laboratory error can also produce false positive results. Thus, it is recommended that the ELISA test be repeated at least once on all seropositive specimens before the result is reported to the patient. The western blot test appears to be more specific and less sensitive than the ELISA. Studies of asymptomatic seropositive homosexual men followed for 2-5 years have found that over 50% remain asymptomatic, 5-19% develop full blown AIDS, and 25% develop signs suggestive of the AIDS-related complex. Asymptomatic patients with positive ELISA tests should be made aware of early signs and symptoms of AIDS. Other data suggest that seropositive patients have the HTLV-III virus in their blood, semen, and/or saliva and can transmit the infection. Precautions to prevent transmission, such as the use of condoms, should be taken by such patients. Physicians should be sensitive to the fear and anxiety that a positive ELISA test will create.

    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

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

  3. Educating Brazilian workers about AIDS.

    1991-12-01

    This article contains a the script for a slide-tape presentation entitled Working Against AIDS, a presentation developed by the Brazil Family Planning Association (BEMFAM) which is designed to debunk common misconceptions about the disease. This audio-visual, which targets Brazilian workers, can be used during talks, seminars, and meetings. A discussion of the issues involved usually follows the presentation of Working Against AIDS. The presentation contains 30 illustrated slides (these are included in the article). The presentation begins by explaining that much of the information concerning AIDS is prejudicial and misleading. The next few slides point out some of the common misconceptions about AIDS, such as claims denying the existence of the disease, or suggestions that only homosexuals and prostitutes are at risk. The presentation then goes on to explain the ways in which the virus can and cannot be transmitted. Then it discusses how the virus destroys the body's natural defenses and explains the ensuing symptoms. Slides 14 and 15 point out that no cure yet exists for AIDS, making prevention essential. Slides 16-23 explain what actions are considered to be high risk and which ones do not entail risk. Noting that AIDS can be prevented, slide 24 says that the disease should not present an obstacle to spontaneous manifestations of human relations. The next slide explains that condoms should always be used when having sex with someone who could be infected with AIDS. Finally slides 26-30 demonstrate the proper way to use and dispose of a condom.

    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...

  12. A candidate HIV/AIDS vaccine (MVA-B lacking vaccinia virus gene C6L enhances memory HIV-1-specific T-cell responses.

    Directory of Open Access Journals (Sweden)

    Juan García-Arriaza

    Full Text Available The vaccinia virus (VACV C6 protein has sequence similarities with the poxvirus family Pox_A46, involved in regulation of host immune responses, but its role is unknown. Here, we have characterized the C6 protein and its effects in virus replication, innate immune sensing and immunogenicity in vivo. C6 is a 18.2 kDa protein, which is expressed early during virus infection and localizes to the cytoplasm of infected cells. Deletion of the C6L gene from the poxvirus vector MVA-B expressing HIV-1 Env, Gag, Pol and Nef antigens from clade B (MVA-B ΔC6L had no effect on virus growth kinetics; therefore C6 protein is not essential for virus replication. The innate immune signals elicited by MVA-B ΔC6L in human macrophages and monocyte-derived dendritic cells (moDCs are characterized by the up-regulation of the expression of IFN-β and IFN-α/β-inducible genes. In a DNA prime/MVA boost immunization protocol in mice, flow cytometry analysis revealed that MVA-B ΔC6L enhanced the magnitude and polyfunctionality of the HIV-1-specific CD4+ and CD8+ T-cell memory immune responses, with most of the HIV-1 responses mediated by the CD8+ T-cell compartment with an effector phenotype. Significantly, while MVA-B induced preferentially Env- and Gag-specific CD8+ T-cell responses, MVA-B ΔC6L induced more Gag-Pol-Nef-specific CD8+ T-cell responses. Furthermore, MVA-B ΔC6L enhanced the levels of antibodies against Env in comparison with MVA-B. These findings revealed that C6 can be considered as an immunomodulator and that deleting C6L gene in MVA-B confers an immunological benefit by enhancing IFN-β-dependent responses and increasing the magnitude and quality of the T-cell memory immune responses to HIV-1 antigens. Our observations are relevant for the improvement of MVA vectors as HIV-1 vaccines.

  13. Mycobacterial Infections in AIDS

    1991-01-01

    Full Text Available Tuberculosis (TB remains uniquely important among acquired immune deficiency syndrome (AIDS-associated opportunistic infections: it presents the greatest public health hazard worldwide, is the most readily curable, and is largely preventable with existing means. Given the expanding pool of human immunodeficiency virus (HIV seropositive persons, particularly in developing nations where Mycobacterium tuberculosis remains a leading health problem, one can expect a continued rise in TB cases during the 1990s. Global efforts to eliminate TB are now inextricably entwined with the effectiveness of measures to curtail the HIV epidemic. Mycobacterium avium complex infection, currently an intractable late complication of aids, may increase in clinical importance as success in managing other opportunistic infections and HIV disease itself improves. Understanding of the pathogenesis and management of mycobacterial diseases should increase rapidly given the renewed research spurred on by the advent of HIV.

    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.

    Science.gov (United States)

    Vardhanabhuti, Saran; Katzenstein, David; Bartlett, John; Kumarasamy, Nagalingeswaran; Wallis, Carole L.

    2016-01-01

    Background. The mechanism of virologic failure (VF) of lopinavir/ritonavir (LPV/r) monotherapy is not well understood. We assessed sequence changes in human immunodeficiency virus-1 reverse-transcriptase (RT) and protease (PR) regions. Methods. Human immunodeficiency virus-1 pol sequences from 34 participants who failed second-line LPV/r monotherapy were obtained at study entry (SE) and VF. Sequence changes were evaluated using phylogenetic analysis and hamming distance. Results. Human immunodeficiency virus-1 sequence change was higher over drug resistance mutation (DRM) sites (median genetic distance, 2.2%; Q1 to Q3, 2.1%–2.5%) from SE to VF compared with non-DRM sites (median genetic distance, 1.3%; Q1 to Q3, 1.0%–1.4%; P < .0001). Evolution over DRM sites was mainly driven by changes in the RT (median genetic distance, 2.7%; Q1 to Q3, 2.2%–3.2%) compared with PR (median genetic distance, 1.1%; Q1 to Q3, 0.0%–1.1%; P < .0001). Most RT DRMs present at SE were lost at VF. At VF, 19 (56%) and 26 (76%) were susceptible to efavirenz/nevirapine and etravirine (ETV)/rilpivirine (RPV), respectively, compared with 1 (3%) and 12 (35%) at SE. Participants who retained nonnucleoside reverse-transcriptase inhibitor (NNRTI) DRMs and those without evolution of LPV/r DRMs had significantly shorter time to VF. Conclusions. The selection of LPV/r DRMs in participants with longer time to VF suggests better adherence and more selective pressure. Fading NNRTI mutations and an increase in genotypic susceptibility to ETV and RPV could allow for the reuse of NNRTI. Further studies are warranted to understand mechanisms of PR failure.

  18. AIDS: there's hope.

    Science.gov (United States)

    1993-06-01

    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.

  20. 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

    Directory of Open Access Journals (Sweden)

    Greenhouse Jack

    2010-03-01

    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.

    2012-06-01

    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

    2016-01-01

    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.

    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.

    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...

  11. The history of AIDS exceptionalism

    Directory of Open Access Journals (Sweden)

    Smith Julia H

    2010-12-01

    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

    Science.gov (United States)

    Hitchcock, B

    1986-01-01

    What is most alarming about Acquired Immune Deficiency Syndrome (AIDS) in East Africa is that it is taboo. The reason for the clamping down on publicity in Kenya is that the government sees AIDS as a killer of tourism, the country's 2nd largest revenue earner. The government of Kenya, like several other African governments, is reacting to the widespread belief in the West that AIDS originated in Africa and that it is rampant in Central and East Africa. These "facts" have yet to be proven conclusively by medical evidence. It is certain that a large percentage of the population of these regions have antibodies to the virus HTLV-III, which causes AIDS. From this, virologists deduce that the people concerned must have been exposed to the AIDS virus. The Western media has exaggerated the African AIDS connection and given the impression that African countries are gripped in raging AIDS epidemics. In response to the alarmist publicity, some African countries have clamped down in information about the disease. The result is that the Western press feels confirmed in its fears and the local population, depending on rumor and heresay, have been living in a state of absolute panic. Instead of allaying fears, the clampdown on news has fueled dangerous rumors at home and frightened away tourists. Whatever may be causing the disease and wherever it may have come from, there is no question at all that there are now confirmed cases of AIDS in East and Central Africa. Thus far, the number of confirmed cases if relatively small, but if governments continue to try and hide the facts from the public, there is a real danger of an epidemic developing. A ministerial statement admits to 7 confirmed AIDS cases in Kenya. There are discrepancies in the reports, however. Doctors interviewed by "New African" in Nairobi recently believe the situation is far more serious than the government admits. Doctors in Kenya make the point that the country is highly vulnerable to the spread of AIDS

    Full Text Available Abstract Background Recent data have shown that HTLV-1 is prevalent among HIV positive patients in Mozambique, although the impact of HTLV-1 infection on HIV disease progression remains controversial. Our aim was to determine the phenotypic profile of T lymphocytes subsets among Mozambican patients co-infected by HIV and HTLV-1. Methods We enrolled 29 patients co-infected by HTLV-1 and HIV (co-infected, 59 patients mono-infected by HIV (HIV and 16 healthy controls (HC, respectively. For phenotypic analysis, cells were stained with the following fluorochrome-labeled anti-human monoclonal antibodies CD4-APC, CD8-PerCP, CD25-PE, CD62L-FITC, CD45RA-FITC. CD45RO-PE, CD38-PE; being analysed by four-colour flow cytometry. Results We initially found that CD4+ T cell counts were significantly higher in co-infected, as compared to HIV groups. Moreover, CD4+ T Lymphocytes from co-infected patients presented significantly higher levels of CD45RO and CD25, but lower levels of CD45RA and CD62L, strongly indicating that CD4+ T cells are more activated under HTLV-1 plus HIV co-infection. Conclusion Our data indicate that HTLV-1/HIV co-infected patients progress with higher CD4+ T cell counts and higher levels of activation markers. In this context, it is conceivable that in co-infected individuals, these higher levels of activation may account for a faster progression to AIDS.

    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.

    The AIDS dilemma continues to escalate, leaving a legacy that probably will affect the nation for years to come. The U.S. Centers for Disease Control, the National Academy of Sciences, and the U.S. Surgeon General have noted that in the absence of a vaccine or treatment for AIDS, education remains the only effective means to prevent the spread of the disease. Thus, schools have an important role in protecting the public health. To respond appropriately to the situation, school personnel must become familiar with relevant information and resources available concerning AIDS. This article first provides essential information about AIDS using a question-and-answer format. Second, policy statements addressing school attendance by students infected with the virus that causes AIDS are presented. Third, hotlines that can be used to obtain more detailed information about AIDS are described. Fourth, organizations that can provide information for school health education about AIDS are identified. Fifth, an annotated list of audiovisual materials that schools can use to provide education about AIDS is provided. Sixth, a bibliography of publications relevant to school health education about AIDS is offered.

    2008-01-01

    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.

    Science.gov (United States)

    1996-12-01

    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

    Bell-Sakyi, Lesley; Attoui, Houssam

    2016-01-01

    While ticks have been known to harbor and transmit pathogenic arboviruses for over 80 years, the application of high-throughput sequencing technologies has revealed that ticks also appear to harbor a diverse range of endogenous tick-only viruses belonging to many different families. Almost nothing is known about these viruses; indeed, it is unclear in most cases whether the identified viral sequences are derived from actual replication-competent viruses or from endogenous virus elements incorporated into the ticks’ genomes. Tick cell lines play an important role in virus discovery and isolation through the identification of novel viruses chronically infecting such cell lines and by acting as host cells to aid in determining whether or not an entire replication-competent, infective virus is present in a sample. Here, we review recent progress in tick-borne virus discovery and comment on the actual and potential applications for tick cell lines in this emerging research area. PMID:27679414

  3. Impacts to HIV/AIDS of gender

    Directory of Open Access Journals (Sweden)

    Emel Taşçı

    2007-03-01

    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.

  4. Why foreign aid fails

    Directory of Open Access Journals (Sweden)

    Prokopijević Miroslav

    2007-01-01

    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.

  5. Deletion of the vaccinia virus gene A46R, encoding for an inhibitor of TLR signalling, is an effective approach to enhance the immunogenicity in mice of the HIV/AIDS vaccine candidate NYVAC-C.

    Directory of Open Access Journals (Sweden)

    Beatriz Perdiguero

    Full Text Available Viruses have developed strategies to counteract signalling through Toll-like receptors (TLRs that are involved in the detection of viruses and induction of proinflammatory cytokines and IFNs. Vaccinia virus (VACV encodes A46 protein which disrupts TLR signalling by interfering with TLR: adaptor interactions. Since the innate immune response to viruses is critical to induce protective immunity, we studied whether deletion of A46R gene in a NYVAC vector expressing HIV-1 Env, Gag, Pol and Nef antigens (NYVAC-C improves immune responses against HIV-1 antigens. This question was examined in human macrophages and in mice infected with a single A46R deletion mutant of the vaccine candidate NYVAC-C (NYVAC-C-ΔA46R. The viral gene A46R is not required for virus replication in primary chicken embryo fibroblast (CEF cells and its deletion in NYVAC-C markedly increases TNF, IL-6 and IL-8 secretion by human macrophages. Analysis of the immune responses elicited in BALB/c mice after DNA prime/NYVAC boost immunization shows that deletion of A46R improves the magnitude of the HIV-1-specific CD4 and CD8 T cell immune responses during adaptive and memory phases, maintains the functional profile observed with the parental NYVAC-C and enhances anti-gp120 humoral response during the memory phase. These findings establish the immunological role of VACV A46R on innate immune responses of macrophages in vitro and antigen-specific T and B cell immune responses in vivo and suggest that deletion of viral inhibitors of TLR signalling is a useful approach for the improvement of poxvirus-based vaccine candidates.

    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. In this paper, meta-analysis techniques are used (i) to determine whether the AEL has established the said interaction terms, and (ii) to identify some of the determinants...... of the differences in results between studies. Taking all available studies in consideration, we find no support for conditionality with respect to policy, while conditionality regarding aid itself is dubious. However, the results differ depending on the authors’ institutional affiliation....

    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.

  15. AIDS in position to ravage India.

    Science.gov (United States)

    Jayaraman, K S

    1996-09-01

    The Joint UN Program on AIDS reports that India has more than 3 million adults infected with HIV, more HIV-infected adults than any other country in the world. By the year 2005, India will have more people infected with HIV than does Africa. Having sex with a Bombay housewife today is at least twice as risky as it was to have sex with a prostitute in the city's red light district in 1988. 2-3% of all women in the city are infected with HIV. There is ignorance, apathy, corruption, and lack of commitment at all levels with regard to HIV/AIDS. Accordingly, India's lackluster campaign against AIDS launched 10 years ago has lost momentum just as the epidemic is exploding and at a time when traditional beliefs about cultural barriers and the sexual behavior of Indian males are being called into question. Considerable homosexual behavior occurs in India. However, the most important factor contributing to the spread of HIV throughout India is the virus' spread from urban areas into small villages, often through migrant laborers. Ignorance, illiteracy, and poverty in villages will make AIDS prevention especially difficult. Indian government policy forbidding the distribution of condoms in prisons, needles to injectable-drug users, and free drugs to AIDS patients further contributes to the spread of HIV.

    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...

  3. AIDS is your business.

    2003-02-01

    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

    Full Text Available It is well known that mucosal tissues contain the largest surface area of the human body and are the front line of natural host defense against various pathogens. In fact, more than 80% of infectious disease pathogens probably gain entry into the susceptible human hosts through open mucosal surfaces. Human immunodeficiency virus type one (HIV-1, a mainly sexually transmitted virus, also primarily targets the vaginal and gastrointestinal mucosa as entry sites for viral transmission, seeding, replication and amplification. Since HIV-1 establishes its early replication in vaginal or rectal mucosal tissues, the induction of sufficient mucosal immunity at the initial site of HIV-1 transmission becomes essential for a protective vaccine. However, despite the fact that current conventional vaccine strategies have remained unsuccessful in preventing HIV-1 infection, sufficient financial support and resources have yet to be given to develop a vaccine able to elicit protective mucosal immunity against sexual transmissions. Interestingly, Chinese ancestors invented variolation through intranasal administration about one thousand years ago, which led to the discovery of a successful smallpox vaccine and the final eradication of the disease. It is the hope for all mankind that the development of a mucosal AIDS vaccine will ultimately help control the AIDS pandemic. In order to discover an effective mucosal AIDS vaccine, it is necessary to have a deep understanding of mucosal immunology and to test various mucosal vaccination strategies.

  8. Nano-ART and NeuroAIDS.

    Science.gov (United States)

    Das, Malay K; Sarma, Anupam; Chakraborty, Tapash

    2016-10-01

    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.

    1996-08-01

    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.

    2011-01-01

    Full Text Available Human immunodeficiency virus (HIV endocrinopathy encompasses a broad spectrum of disorders. Almost all the endocrine organs are virtually affected by HIV infection. HIV can directly alter glandular function. More commonly secondary endocrine dysfunction occurs due to opportunistic infections and neoplasms in immunocompromised state. The complex interaction between HIV infection and endocrine system may be manifested as subtle biochemical and hormonal perturbation to overt glandular failure. Antiretroviral therapy as well as other essential medications often result in adverse endocrinal consequences. Apart from adrenal insufficiency, hypogonadism, diabetes and bone loss, AIDS wasting syndrome and HIV lipodystrophy need special reference. Endocrinal evaluation should proceed as in other patients with suspected endocrine dysfunction. Available treatment options have been shown to improve quality of life and long-term mortality in AIDS patients.

    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.

    Bone marrow gene therapy remains an attractive option for treating chronic immunological diseases, including acquired immunodeficiency syndrome (AIDS) caused by human immunodeficiency virus (HIV). This technology combines the differentiation and expansion capacity of hematopoietic stem cells (HSCs) with long-term expression of therapeutic transgenes using integrating vectors. In this review we summarize the potential of bone marrow gene therapy for the treatment of HIV/AIDS. A broad range of antiviral strategies are discussed, with a particular focus on RNA-based therapies. The idea is to develop a durable gene therapy that lasts the life span of the infected individual, thus contrasting with daily drug regimens to suppress the virus. Different approaches have been proposed to target either the virus or cellular genes encoding co-factors that support virus replication. Some of these therapies have been tested in clinical trials, providing proof of principle that gene therapy is a safe option for treating HIV/AIDS. In this review several topics are discussed, ranging from the selection of the antiviral molecule and the viral target to the optimal vector system for gene delivery and the setup of appropriate preclinical test systems. The molecular mechanisms used to formulate a cure for HIV infection are described, including the latest antiviral strategies and their therapeutic applications. Finally, a potent combination of anti-HIV genes based on our own research program is described. PMID:26193303

    We intended to assess knowledge, attitude, perception, misconception and views (KAP-MV) of family members of PLWHA. A cross-sectional retrospective study conducted in Anti-retroviral centre of Mahatma Gandhi Memorial-MGM hospital, Warangal, Telangana, South-India from July to September 2014. A questionnaire containing 41 items was distributed among adult family members accompanying patients living with HIV/AIDS-PLWHA. Level of KAP-MV was categorized into poor (0-28), average (29-55) and good (56-82). Analysis was performed by Pearson's Chi square, analysis of variance and Spearman's correlation test on 41 variables using SPSS version 21 and p < 0.01. 538 questionnaires were distributed, response rate was (96 %). On knowledge scale, respondents had a mean score of 8.0 ± 1.7, attitude 5.8 ± 3.4, perception 23.4 ± 4.1, misconceptions 8.0 ± 2.1 and views 8.0 ± 3.9. The respondents mean score was 53.2 ± 9.1 (64.9 %). Overall, level of education, marital status, religious beliefs, and employment status has significant (p < 0.001) associations with KAP-MV. Knowledge was significantly correlated with respondents' attitude (r = -0.15, p < 0.001), perception (0.39; p < 0.001), and views (0.381; p < 0.001). Family members of PLWHA with less knowledge score had more negative attitude, perception and views. Level of education, marital status, religious beliefs and employment status were identified as key barriers. Interventions targeting family members of PLWHA are warranted. Practice implications are as follows: Encourage role of family members.Deploy interventions.Minimize barriers.Change misconceptions.

    Full Text Available More than 40 million people worldwide have been infected with human immunodeficiency virus (HIV since it was first reported in 1981. Over 25 million of these have lost their lives to the disease. Most of the studies related to HIV/AIDS have been conducted in stable populations across the globe. Few of these studies have been devoted to displaced populations, particularly those in areas of conflict. Displaced populations that are forced to leave their homes in most cases find themselves in unfamiliar territories, often poor and hungry. Many of them become refugees and internally displaced people (IDPs. The objective of this review was to address a number of different social determinants of HIV/AIDS in displaced populations in areas of conflict. A comprehensive review of peer reviewed literature published in English between 1990 and 2010 obtained through an open search of PUBMED database using key words such as “HIV and war”, “HIV/AIDS and conflict”, “AIDS and security” was conducted. Twelve different studies that looked at the implications of HIV/AIDS in conflict or displaced populations were retrieved. The review revealed that there were various factors influencing conflict and HIV/AIDS such as forced population displacement, breakdown of traditional sexual norms, lack of health infrastructure, and poverty and powerlessness of women and children. Social determinants of increased HIV/AIDS prevalence in displaced populations are scarcity of food, poverty, insecurity of displaced populations and gender power differentials.

    2001-06-01

    For 20 years, Hospital Albert Schweitzer (HAS) in Haiti's Artibonite Valley has struggled with the evolving acquired immune deficiency syndrome (AIDS) epidemic. Initial efforts to confront the disease met numerous obstacles including denial, stigmatization, powerlessness, and mistrust. Over time, HAS and local community organizations developed a new approach to the AIDS problem. The first step in this approach flowed from the founding principle of HAS: Reverence for Life; hospital staff and community leaders provided hospice care to people dying of AIDS. Caring for people with AIDS and hearing the stories of people with AIDS quickly generated sympathy and a personal sense of vulnerability among community leaders and created a desire for community human immunodeficiency virus (HIV) education and prevention. Using the stories of people with AIDS as a basis, a community education program was launched. More than 1,000 church leaders, voodoo priests, and schoolteachers were trained. The majority of these leaders returned to their communities and started creative and unexpected initiatives to confront the AIDS problem.

  4. The chemical bases of the various AIDS epidemics: recreational drugs, anti-viral chemotherapy and malnutrition

    2003-06-01

    In 1981 a new epidemic of about two-dozen heterogeneous diseases began to strike non-randomly growing numbers of male homosexuals and mostly male intravenous drug users in the US and Europe. Assuming immunodeficiency as the common denominator the US Centers for Disease Control (CDC) termed the epidemic, AIDS, for acquired immunodeficiency syndrome. From 1981–1984 leading researchers including those from the CDC proposed that recreational drug use was the cause of AIDS, because of exact correlations and of drug-specific diseases. However, in 1984 US government researchers proposed that a virus, now termed human immunodeficiency virus (HIV), is the cause of the non-random epidemics of the US and Europe but also of a new, sexually random epidemic in Africa. The virus-AIDS hypothesis was instantly accepted, but it is burdened with numerous paradoxes, none of which could be resolved by 2003: Why is there no HIV in most AIDS patients, only antibodies against it? Why would HIV take 10 years from infection to AIDS? Why is AIDS not self-limiting via antiviral immunity? Why is there no vaccine against AIDS? Why is AIDS in the US and Europe not random like other viral epidemics? Why did AIDS not rise and then decline exponentially owing to antiviral immunity like all other viral epidemics? Why is AIDS not contagious? Why would only HIV carriers get AIDS who use either recreational or anti-HIV drugs or are subject to malnutrition? Why is the mortality of HIV-antibody-positives treated with anti-HIV drugs 7–9%, but that of all (mostly untreated) HIV-positives globally is only 1.4%? Here we propose that AIDS is a collection of chemical epidemics, caused by recreational drugs, anti-HIV drugs, and malnutrition. According to this hypothesis AIDS is not contagious, not immunogenic, not treatable by vaccines or antiviral drugs, and HIV is just a passenger virus. The hypothesis explains why AIDS epidemics strike non-randomly if caused by drugs and randomly if caused by

    1994-03-01

    A heuristic approach employing Newman's method for pattern identification was used to examine the theory of health as expanding consciousness in persons with human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS). Themes derived from the interview of nine gay men portrayed a pattern of alienation during childhood, followed by a breaking away from family, and progressing to cycles of aloneness and searching. Recognition of HIV/AIDS in their lives brought them to a turning point of more meaningful connectedness. This pattern is viewed as expanding consciousness and possibly a phenomenon of cultural evolution. PMID:8203827

    AIDS is an acquired immunodeficiency syndrome defined by a severe depletion of T cells and over 20 conventional degenerative and neoplastic diseases. In the U.S. and Europe, AIDS correlates to 95% with risk factors, such as about 8 years of promiscuous male homosexuality, intravenous drug use, or hemophilia. Since AIDS also correlates with antibody to a retrovirus, confirmed in about 40% of American cases, it has been hypothesized that this virus causes AIDS by killing T cells. Consequently, ...

    Objective To investigate the status of HIV/AIDS related discrimination and its correlation with compliableness in using anti - virus drug among former blood donors. Methods A survey of 416 HIV infected former blood donors was conducted from 2008 to 2009 in Henan province, China. The participants experienced HIV/AIDS related stigma and discrimination year were assessed, and association between HIV discrimination and compliableness in using anti - virus drug etc. were analyzed. Blood specimens were drawn from each participant to test of CD4+ T cells counts. Results Totally 140(33. 7% ) of participants once experienced HIV/AIDS related discrimination, 24. 8% was afraid or not dare to visit neighbors/relatives, 6. 3% were forced to changed hospital to treat diseases, and 9. 2% of PLWHs who was receiving HAART treated forgot to take ART drugs within the past month. Logistic analysis identified that, HAART treated PLWHs felt significantly lower proportion of discrimination compared with those who was not currently receiving HAART treatment [32. 9% vs 65. 5% , OR(95% CI) =0. 5(0. 3 - 0. 8) ,P < 0. 001 ]. And those HAART treated PLWHs who did not experience HIV/ ADIS related discrimination had significantly lower proportion of missing to take HAART drugs than those HAART treated PLWHs who experienced HIV/ADIS related discrimination(1.3% vs 45.8% , OR =0.2, 95%CI:0.0 -0. 1,P<0.001). CD4+ T counts had no statistical correlation with discrimination. Conclusion HARRT can decrease the feeling of HIV/AIDS related discrimination, but the suffered HIV/AIDS discrimination may increase the risk of poor compliance for taking HAART drugs. More propaganda and education should be given to the general population and health care system etc. To eliminate their discrimination to PLWH, and to improve PLWHs' quality level of life.%目的 了解河南省既往采供血途径HIV感染者感受到的艾滋病相关歧视与服药依从性等因素之间的关联性.方法 对河南省416采供

    A knowledge-based system (KBS), First Aid Advisor (FAA), is developed to provide a guidance for either a trained or untrained person to take some emergent actions to rescue the victim from life-threatening hazard or to prevent from causing serious problem before the Emergency Medical Service System (EMS) personnels arrive the scene. The First Aid Advisor will collect victim`s information by interacting with the user through a sequence of questions, analyze the victim`s problem, and give instructions step by step before offering a final advice. Since all the possible conditions are taken into consideration, it will guide the user to perform first aid from the most to the least urgent step for the victim. Furthermore, it will offer a suitable first aid advice for victim and eliminate the possibility of wrong actions done by trained person due to carelessness or nervousness. Offering advice to handle problems involving life-threatening conditions is the main objective of this system. In this paper, we will describe six major components of FAA and their respective tasks. Decision tables and dependency diagrams used in FAA implementation will also be described. System performance issues will conclude the paper.

    2016-01-01

    Full Text Available Human immunodeficiency virus causes a severe disease in humans, referred to as immune deficiency syndrome. Studies on the interaction between host genetic factors and the virus have revealed dozens of genes that impact diverse processes in the AIDS disease. To resolve more genetic factors related to AIDS, a canonical correlation analysis was used to determine the correlation between AIDS restriction and metabolic pathway gene expression. The results show that HIV-1 postentry cellular viral cofactors from AIDS restriction genes are coexpressed in human transcriptome microarray datasets. Further, the purine metabolism pathway comprises novel host factors that are coexpressed with AIDS restriction genes. Using a canonical correlation analysis for expression is a reliable approach to exploring the mechanism underlying AIDS.

    The strong association of Zika virus infection with congenital defects has led to questions of how a flavivirus is capable of crossing the placental barrier to reach the fetal brain. Here, we demonstrate permissive Zika virus infection of primary human placental macrophages, commonly referred to as Hofbauer cells, and placental villous fibroblasts. We also demonstrate Zika virus infection of Hofbauer cells within the context of the tissue ex vivo using term placental villous explants. In addition to amplifying infectious virus within a usually inaccessible area, the putative migratory activities of Hofbauer cells may aid in dissemination of Zika virus to the fetal brain. Understanding the susceptibility of placenta-specific cell types will aid future work around and understanding of Zika virus–associated pregnancy complications.

    The worm, Trojan horse, bacterium, and virus are destructive programs that attack information stored in a computer's memory. Virus programs, which propagate by incorporating copies of themselves into other programs, are a growing menace in the late-1980s world of unprotected, networked workstations and personal computers. Limited immunity is offered by memory protection hardware, digitally authenticated object programs,and antibody programs that kill specific viruses. Additional immunity can be gained from the practice of digital hygiene, primarily the refusal to use software from untrusted sources. Full immunity requires attention in a social dimension, the accountability of programmers.

    Full Text Available The problem of AIDS had not been recognized up to 1981 and in 1984 it was found that HIV virus is factor of this disease. For the time beings AIDS/HIV infection has chanched to a pandemic and cases affected to it are now reported from all over the world. In our country the first case was reported in 1987. Regarding the importance of disease and recognition of its prevention and transmission routes, based on disease epidemiology in country, this survey was conducted. This study was performed in 1999-2000 and is retrospective descriptive study. The main purpose of study is epidemiology of AIDS in Iran from beginning until now. Total information of cases of AIDS/HIV from beginning in Iran and all performed activities were obtained from ministry of health center for disease control-AIDS Dept. 95 files existing in the archives of Imam Khomeini hospital related to AIDS were also studied. 1953 cases of HIV+ have been reported until March of year 2000. At the same time 250 cases of AIDS have been reported which 215 of them died. Among transmission routes, in AIDS disease the most common way of transmission was transfusion of infected blood or its components but in HIV+ case the most one was drug injection. With respect to age, the higher and lower rate of affected people were in 30-39 and 0-4 ranges years respectively. The sex percentage in AIDS affected and HIV+ persons were 90.8% and 9.2%; 95.2% and 4.8% male and female respectively. 130 from 1953 HIV+ cases had travel to abroad.

    Does perceived corruption in recipient countries reduce support for foreign aid in donor countries? This under-explored yet salient question is examined using the 2009 Eurobarometer survey for the 27 EU countries. We suggest that perceived corruption can cause aid fatigue but that this relationship...... is highly contextualized. The results show that perceptions about corruption in developing countries reduce overall support for aid among respondents in donor countries. However, this effect is mitigated by country and contextual-level effects and different understandings of what we call the “aid......-corruption paradox,” namely that the need for foreign aid is often the greatest in corrupt environments. Three different dynamics of the aid-corruption paradox influence support for aid: moral, pragmatic, and strategic understandings. In EU-15 countries, the effect of perceived corruption in recipient states on aid...

    International Nuclear Information System (INIS)

    Cell lines derived from Kaposi sarcoma lesions of patients with AIDS (AIDS-KS cells) produce several cytokines, including an endothelial cell growth factor, interleukin 1β, and basic fibroblast growth factor. Since exposure to human immunodeficiency virus increases interleukin 6 (IL-6) production in monocytes and endothelial cells produce IL-6, the authors examined IL-6 expression and response in AIDS-KS cell lines and IL-6 expression in AIDS Kaposi sarcoma tissue. The AIDS-KS cell lines (N521J and EKS3) secreted large amounts of immunoreactive and biologically active IL-6. The authors found both IL-6 and IL-6 receptor (IL-6-R) RNA by slot blot hybridization analysis of AIDS-KS cells. The IL-6-R was functional, as [3H]thymidine incorporation by AIDS-KS cells increased significantly after exposure to human recombinant IL-6 (hrIL-6) at >10 units/ml. When AIDS-KS cells (EKS3) were exposed to IL-6 antisense oligonucleotide, cellular proliferation decreased by nearly two-thirds, with a corresponding decrease in the production of IL-6. These results show that both IL-6 and IL-6-R are produced by AIDS-KS cells and that IL-6 is required for optimal AIDS-KS cell proliferation, and they suggest that IL-6 is an autocrine growth factor for AIDS-KS cells

    The spectrum of pathology affecting the central nervous system (CNS) in patients suffering from acquired immunodeficiency syndrome (AIDS) is broad and comprises predominantly opportunistic infections and neoplasms. It is estimated that approximately one-third of all patients with AIDS develop neurological complications. The organisms responsible for AIDS are human retroviruses: primarily the human immunodeficiency virus type 1 (HIV). In this review we shall focus on the neurological complications of HIV and AIDS which are applicable to the more frequently occurring intracranial infective organisms. Attention will be paid specifically to those CNS manifestations occurring in the adult HIV and AIDS population as infection in the paediatric HIV and AIDS group, although bearing some similarities, demonstrates some important differences

  11. Women and AIDS care: coping with "triple jeopardy".

    Science.gov (United States)

    1995-11-01

    Women in developing countries are at "triple jeopardy" in the acquired immunodeficiency syndrome (AIDS) epidemic. As women, a combination of biological, social, and economic risk factors increase their vulnerability to human immunodeficiency virus (HIV) infection. As mothers, they can infect their children with HIV. And, as society's traditional caregivers, women are burdened with the care of sick family members. The most effective AIDS programs deliver counseling and social support to family caregivers as well as clinical management of AIDS-related illnesses and nursing care. In several African countries, the physical, financial, and emotional demands associated with home care of AIDS patients are addressed by mobile teams of health workers and counselors. Government health services and nongovernmental organizations are training village health workers to help people cope with the fear and stigma associated with AIDS. These community AIDS workers conduct formal and informal educational sessions, visit homes to provide counseling, instruct caregivers on precautions to protect themselves from infection, and refer people for HIV testing and medical treatment. A multisectoral approach to providing the mix of services required is the best strategy for maximizing program coverage while maintaining a high quality of services.

    This compendium is the result of an effort to compile, organize, and rapidly publish as much relevant molecular data concerning the human immunodeficiency viruses (HIV) and related retroviruses as possible. The scope of the compendium and database is best summarized by the four parts that it comprises: (1) Nucleic Acid Alignments, (2) Amino Acid Alignments, (3) Reviews and Analyses, and (4) Related Sequences. Information within all the parts is updated throughout the year on the Web site, http://hiv-web.lanl.gov. This year we are not including floppy diskettes as the entire compendium is available both at our Web site and at our ftp site. If you need floppy diskettes please contact either Bette Korber (btk@t10.lanl.gov) or Kersti Rock (karm@t10.lanl.gov) by email or fax ((505) 665-4453). While this publication could take the form of a review or sequence monograph, it is not so conceived. Instead, the literature from which the database is derived has simply been summarized and some elementary computational analyses have been performed upon the data. Interpretation and commentary have been avoided insofar as possible so that the reader can form his or her own judgments concerning the complex information. The exception to this are reviews submitted by experts in areas deemed of particular and basic importance to research involving AIDS viral sequence information. These are included in Part III, and are contributed by scientists with particular expertise in the area of interest. In addition to the general descriptions below of the parts of the compendium, the user should read the individual introductions for each part.

    Since 1982 (Hauser and co-workers), literature has reported focal cerebral tissue charges in AIDS patients whose diagnosis was unclear at first but which could be identified finally as florid toxoplasmosis encephalitis by biopsy and autopsy. It was found that the value of otherwise reliable serological tests (KBR, Sabin-Feldmann tests, etc.) is questionable in patients with severely impaired or incompetent immune systems, and, in particular, that a negative or uncharacteristic test result may not preclude any opportunistic infection process. Furthermore, isolation of Toxoplasma gondii or specific antibodies from the cerebrospinal fluid will be successful in exceptional cases only. In patients with AIDS or lymphadenopathy syndrome, the differential diagnosis will have to include - first and foremost - reactivated toxoplasma infection (not newly acquired, as a rule) if central neurological symptoms occur.

  1. Redirecting British foreign aid.

    Science.gov (United States)

    Dean, M

    1994-01-01

    Britain has longed followed a disease-control strategy for providing aid in the health sector to developing, low-income countries. Given, however, the high level of waste upon tertiary care and specialized medicine in current health programs of low-income countries as documented by the World Bank; the poor performance of existing general government hospitals and clinics; and the poor image of Third World health systems in the eyes of Western officials and government ministers, the chief health advisor of the Overseas Development Administration has called for a drastic redirection of policy toward development aid. Specifically, a shift away from a specific-disease control approach toward an overall, sweeping reform of the health sector in developing countries is urged. The level of waste needs to be reduced and more attention given to the poor. Unless such changes result, government ministers will grow increasingly reluctant to provide tangible aid to the health sectors of countries in need. The availability of such funds invested in effective, well-managed health programs will grow more critical to health in the Third World as populations shift away from communicable disease morbidity and mortality toward illnesses which are of a more noncommunicable nature such as stroke and cancer.

    1988-03-01

    In order to be effective, the national effort to contain the spread of Acquired Immunodeficiency Syndrome (AIDS) must include a youth focus. Knowledge of adolescent sexual behavior, drug use, and sexually transmitted diseases suggests that many adolescents are in jeopardy of acquiring Human Immunodeficiency Virus (HIV) infections; and they are among those most likely to benefit from preventative efforts as they explore adult roles and lifestyles. Preventative education should particularly target gay and other homosexually active young men. Effective teaching uses a variety of approaches and media, both inside and outside the classroom. Learning about AIDS is most likely to effect behavioral change when accompanied by other programs to build social supports, self-esteem, and positive identity. The ethical and rational use of HIV antibody testing may be a helpful adjunct to education for certain adolescents. Ultimately, our society's ability to address complex, associated social issues will determine our ability to control AIDS. PMID:3283090

In spite of the fact that both innate and adaptive immunities are indispensable and numerous cells participate in the anti-HIV immunity, memory CD4 T-cells are indisputably the key cells organizing all immune actions against HIV while being the targets of HIV. Here we present a view and multidisciplinary approaches to HIV/AIDS eradication and cure. We aim at memory CD4 T-cells, utilizing the stem cell properties of these cells to reprogram an anti-HIV memory repertoire to eliminate the viral reservoir, toward achieving an AIDS-free world.

  5. MR imaging of white matter lesions in AIDS

    International Nuclear Information System (INIS)

    Autopsy reports have shown white-matter abnormalities from infection of the brain by the human immunodeficiency virus (HIV), the agent that causes acquired immunodeficiency syndrome (AIDS). The authors observed abnormal signal on T2-weighted images in the white matter of approximately one third of all AIDS patients. Of 50 patients with white-matter lesions, approximately two thirds had no clinical or biopsy evidence of cytomegalovirus, toxoplasmosis, PML, or lymphoma. Several patients were shown at autopsy to have isolated evidence of HIV encephalitis. The authors conclude that white-matter lesions are common in AIDS and are frequently caused by infection with HIV. Some MR findings may be helpful in characterizing these lesions, but the various etiologies are often indistinguishable

This disease emerged with a series of stigmata, injuring personal integrity of those who suffer from it. Methods: A descriptive study made in Cienfuegos, in which 120 adolescents and 29 PVHIV were inquired and also conferences about this illness were given. Results and Conclusions: The 120 inquired affirmed they knew about the disease and was receiving information regarding it. The majority identifies blood, vaginal secretions, semen, sharing contaminated needles and syringes as main ways of transmission, they also consider that keeping a stable mate friend is the best way to protect themselves. The 50,8% think the names of the infected should be informed to population, and the 15,% is worried about sharing their working or scholar life with them. The 26% think the infected people should live isolated in a sanatorium. On the other hand, 16 PVHIV said they have felt sometimes discriminated, and 11 stated that at the time of asking for medical help, the personnel have attended them in a despicable manner. 3 of them felt the familiar rejection, and 7 stated that the community and his very friends were getting away from them.

I peptidi antimicrobici sono una classe di importanti molecole coinvolte nella risposta immunitaria innata caratterizzati sia da attività sia antibatterica che antimicrobica e che, visto il loro ruolo come barriera primaria contro i patogeni, probabilmente ricoprouno un r...

  13. Beyond SHM and CSR: AID and related cytidine deaminases in the host response to viral infection.

    Rosenberg, Brad R; Papavasiliou, F Nina

    2007-01-01

    As the primary effector of immunoglobulin somatic hypermutation (SHM) and class switch recombination (CSR), activation-induced cytidine deaminase (AID) serves an important function in the adaptive immune response. Recent advances have demonstrated that AID and a group of closely related cytidine deaminases, the APOBEC3 proteins, also act in the innate host response to viral infection. Antiviral activity was first attributed to APOBEC3G as a potent inhibitor of HIV. It is now apparent that the targets of the APOBEC3 proteins extend beyond HIV, with family members acting against a wide variety of viruses as well as host-encoded retrotransposable genetic elements. Although it appears to function through a different mechanism, AID also possesses antiviral properties. Independent of its antibody diversification functions, AID protects against transformation by Abelson murine leukemia virus (Ab-MLV), an oncogenic retrovirus. Additionally, AID has been implicated in the host response to other pathogenic viruses. These emerging roles for the AID/APOBEC cytidine deaminases in viral infection suggest an intriguing evolutionary connection of innate and adaptive immune mechanisms.

    Since the first cases of a new acquired immunodeficiency syndrome (AIDS) described by Oleske et al. and Rubinstein et al. in children in 1983, we have witnessed an ever-increasing number of such observations. As serology is not being performed on all pregnant women in many European countries, obstetricians must try to identify those belonging to risk groups: intravenous drug abusers, natives of affected regions or women having travelled to these areas, women having numerous sexual partners, presenting with other sexually transmitted diseases or living with infected individuals, prostitutes, transfused women. If the woman belongs to risk groups, HIV antibody testing is to be done at the beginning of pregnancy. The risks for the mother remain ill-defined, due in part to the difficulties inherent in keeping track of heroin abusers. Aggravation is certain if the mother is affected with AIDS or an associated syndrome called ARC (AIDS-related complex). It is debatable and at least rarer if the mother presents no clinical symptoms. Infant risks are becoming better known. The existence of materno-fetal contamination by transplacental route is undebatable. However, contamination during delivery or during the passage through the maternal genital tract cannot be excluded. The proportion of contaminated infants is approximately 40%. The disease in the infant is highly dangerous. According to these data, the procedure adopted by most obstetricians is the following: abortion is recommended at the first trimester of the pregnancy, a free choice is left open for the woman at the second trimester and at the third trimester delivery is carried out naturally. Caesarean sections are only done when there are obstetrical indications.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:3281969

    Synthetic genome recoding is a novel method of generating viruses with altered phenotypes, whereby many synonymous mutations are introduced into the protein coding region of the virus genome without altering the encoded proteins. Virus genome recoding with large numbers of slightly deleterious mutations has produced attenuated forms of several RNA viruses. Virus genome recoding can also aid in investigating virus interactions with innate immune responses, identifying functional virus genome structures, strategically ameliorating cis-inhibitory signaling sequences related to complex viral functions, to unravel the relevance of codon usage for the temporal regulation of viral gene expression and improving our knowledge of virus mutational robustness and adaptability. The present review discusses the impacts of synonymous genome recoding with regard to expanding our comprehension of virus biology, and the development of new and better therapeutic strategies.

    Human immunodeficiency virus-infected people discontinuing therapy experience a rebound in the virus level (hereafter, "rebound virus") from a persistent reservoir. We examined 10 samples from patients in AIDS Clinical Trials Group study A5068 with rebound virus, using single-genome amplification and Primer ID deep sequencing, to assess env genetic diversity of the virus population. Most rebound-virus populations showed significant diversity. All env examined required high levels of CD4 for entry, consistent with selection of replication in CD4(+) T cells. These results indicate that most people discontinuing therapy release a diverse population of virus and that this released virus has entry features of virus selected for replication in CD4(+) T cells, rather than in myeloid cells.

    The myths and prejudices that distort the reality and hide the true causes and effects of natural and social phenomena related to sexuality have a fertile ground in AIDS, given its obvious link to sex. The alarming spread of AIDS has been 1 result of these myths and prejudices. Human beings are sexual by nature; genital organs determine sex and also induce sexual behavior. It is by not fairly well accepted that an individual's sexuality exists from birth. Puberty usually begins at 12-16 years for both sexes. The physical changes of puberty terminate in the ability of the female to conceive and the male to procreate. The sexual excitation of adolescents resulting from production of various hormones can only be eliminated by some type of sexual satisfaction or sublimation. Sexuality, according to Freud, is an organizing principle of the personality. The sexual organs exist not merely for reproduction but to provide pleasure. Puberty signifies entry into active sex life. But the ideological structure of society, perpetuated by the family, schools, religion, the mass media, and other social institutions, sends confused signals to adolescents, requiring abstinence and virginity until marriage for women while encouraging sexual adventures for men. Adolescents are confronted by their new sexual feelings in the midst of a virtual bombardment of visual sexual stimuli from the mass media. It becomes impossible for adolescents to satisfy the requirements of appearances while also resolving the problems and pressures of their newly gained sexual maturity. Many adolescents become sexually active, and the problem is not to prevent sexual activity but to improve the conditions under which it occurs. Adolescents, lacking education and information about sex, begin their sex lives without protection. AIDS has now been added to the list of dire consequences that can result. A true sex education beginning in the home is needed to enable young people to develop healthy and full sex

    With new modeling techniques for estimating and pricing the risks of natural disasters, the donor community is now in a position to help the poor cope with the economic repercussions of disasters by assisting before they happen. Such assistance is possible with the advent of novel insurance instruments for transferring catastrophe risks to the global financial markets. Donor-supported risk-transfer programs not only would leverage limited disaster-aid budgets but also would free recipient countries from depending on the vagaries of postdisaster assistance. Both donors and recipients stand to gain, especially because the instruments can be closely coupled with preventive measures. PMID:16099976

    Coll Seck, A M

    1990-10-01

    The theme of "World Aids Day" for 1990 was "Women and AIDS." This theme was chosen because of the devastating effects AIDS has on women. The World Health Organization's (WHO) latest figures state that women represent 1/3 of the estimated 6 million people infected with AIDS worldwide. The majority of these women are in Sub-Saharan Africa (SSA) and the Caribbean. The outcomes of a recent study done in a Central African country showed that women were 4 times more susceptible to getting AIDS than men, in spite of the fact that there are more men than women in this area of SSA. The reasons that women are so vulnerable are multiple: illiteracy, lack of access to information, prejudices, sexual taboos, and an economic dependency which have all led women towards prostitution and the growing incidence of hetero sexual transmission of AIDS in SSA. Prostitutes are 88% seropositive in Kigali; 16% in Dakar and 90% in Nairobi. 10% of all AIDS cases in SSA are due to transfusions where the blood banks are not monitored because women are loosing large quantities of blood through abortions, hemorrhages, deliveries and chronic anemia due to continuous pregnancies that are badly spaced. Additional problems for women are transmitting AIDS to their babies -- 25-30% of pediatric AIDS are transmitted from mother to child through "vertical transmission (VT)." This VT is a serious problem in East Africa where a survey in Uganda showed that 24% of pregnant women were infected with AIDS. The WHO estimated that between 1980-1987, 80,000 children were infected with AIDS of which 80% died before age 5. AIDS in SSA is taking its toll on women who face environmental, socio-cultural, political and economic discrimination. Such a loss to AIDS to incalculable to society.

  5. Talking about AIDS

    Directory of Open Access Journals (Sweden)

    2003-09-01

    Full Text Available This paper explores the significance of social relationships to two important stages in the process of sexual behavioral change in response to increased HIV/AIDS risk in rural Africa: the perceived risk of becoming HIV-infected through unprotected sexual intercourse and the preferred methods of protection either through sexual fidelity, or through condom use. The empirical analyses are based on cross-sectional data from the 'Kenyan Diffusion and Ideational Change Project' (KDICP which provides information about AIDS-related, ego-centered communication networks of Kenyan men and women. The results show that perceived risks, as well as preferred methods of protection against HIV-infection, depend in general on the prevailing perceptions and favored protective methods within personal communication networks. However, different influential network properties can be found. The risk-perceptions of women are shaped by strong relationships and cohesive network structures. Male's risk perception depends more on the number of risk-perceivers in their communication networks. Heterogeneous relationships of various kinds are influential on women's and men's probability of favoring sexual faithfulness as a method of protection against HIV-infection.

    Full Text Available Adolescence (10- 19 years is a phase of physical growth and development accompanied by sexual maturation, often leading to intimate relationships. Adolescent HIV/AIDS is a separate epidemic and needs to be handled and managed separately from adult HIV. The adolescents can be subdivided into student, slum and street youth; street adolescents being most vulnerable to HIV/AIDS. Among various risk factors and situations for adolescents contracting HIV virus are adolescent sex workers, child trafficking, child labor, migrant population, childhood sexual abuse, coercive sex with an older person and biologic (immature reproductive tract as well as psychological vulnerability. The most common mode of transmission is heterosexual, yet increasing number of perinatally infected children are entering adolescence. This is due to "bimodal progression" (rapid and slow progressors among the vertically infected children. Clinically, the HIV infected adolescents present as physically stunted individuals, with delayed puberty and adrenarche. Mental illness and substance abuse are important co-morbidities. The disclosure and declaration of HIV status to self and family is challenging and guilt in sexually infected adolescents and tendency to blame parents if vertically affected need special consideration and proper counseling. Serodiscordance of the twins and difference in disease progression of seroconcordant twins are added causes of emotional trauma. Treatment related issues revolve around the when and what of initiation of ART; the choice of antiretrovirals and their dosages; issues related to long term ADRs; sense of disinhibition following ART commencement; adherence and resistance.

    Wallace, Robert G

    2003-03-01

    During the 1990s, the number of new AIDS cases in New York City, USA, declined precipitously. The declines, beginning before highly active antiretroviral therapy (HAART) was introduced, were geographically heterogeneous across two New York City boroughs analyzed. From 1993 to 1998, zip codes in Lower Manhattan, with large white and affluent populations, had declines as much as 55% more than the rest of Manhattan. Bronx zip codes underwent still lesser declines. Declines also differed within zip codes among subpopulations. White zip code populations tended to have greater declines than Latino populations, which in turn tended to have greater declines than black populations. According to bivariate and stepwise regressions, an array of socioeconomic and community stress variables acted in combination on the decline in New York AIDS. Manhattan's declines in total AIDS incidence were primarily defined by changes in AIDS incidence for whites and for men who have sex with men, racial segregation, and the proportions of households in upper income classes and under rent stress. Bronx declines in total AIDS are principally explained by a broader range of income classes, and social instability as marked by housing overcrowding and cirrhosis and drug mortalities. Whatever the combination of proximate causes for the decline in AIDS incidence in 1990s New York (educational campaigns, HAART, demographic stochasticity), the decline was shaped by the city's socioeconomic structure and political and ecological history. That structure and history generates the geographically defined aggregates of behaviors that promote or impede AIDS decline. Such spatial heterogeneity may provide for HIV refugia, areas where the virus can weather the epidemic's contraction, a troubling possibility with the accelerating microbicidal failures of combination therapies.

    1989-05-01

    Feline immunodeficiency virus (FIV) (formerly feline T-lymphotropic lentivirus or FTLV) was first isolated from a group of cats in Petaluma, California in 1986. The virus is a typical lentivirus in gross and structural morphology. It replicates preferentially but not exclusively in feline T-lymphoblastoid cells, where it causes a characteristic cytopathic effect. The major structural proteins are 10, 17 (small gag), 28 (major core), 31 (endonuclease?), 41 (transmembrane?), 52 (core precursor polyprotein), 54/62 (reverse transcriptase?), and 110/130 (major envelope) kilodaltons in size. The various proteins are antigenically distinguishable from those of other lentiviruses, although serum from EIAV-infected horses will cross-react with some FIV antigens. Kittens experimentally infected with FIV manifest a transient (several days to 2 weeks) fever and neutropenia beginning 4 to 8 weeks after inoculation. This is associated with a generalized lymphadenopathy that persists for up to 9 months. Most cats recover from this initial phase of the disease and become lifelong carriers of the virus. Complete recovery does not occur to any extent in nature or in the laboratory setting. One experimentally infected cat died from a myeloproliferative disorder several months after infection. The terminal AIDS-like phase of the illness has been seen mainly in naturally infected cats. It appears a year or more following the initial infection in an unknown proportion of infected animals. FIV has been identified in cats from all parts of the world. It is most prevalent in high density populations of free roaming cats (feral and pet), and is very uncommon in closed purebred catteries. Male cats are twice as likely to become infected as females. Older male cats adopted as feral or stray animals are at the highest risk of infection, therefore. The infection rate among freely roaming cats rises throughout life, and reaches levels ranging from less than 1% to 12% or more depending on the

  6. AIDS and sex tourism.

    Science.gov (United States)

    Herold, E S; Van Kerkwijk, C

    1992-01-01

    Tourists traveling internationally lower their inhibitions and take greater risks than they would typically in their home cultures. Loneliness, boredom, and a sense of freedom contribute to this behavioral change. Some tourists travel internationally in search of sexual gratification. This motivation may be actively conscious or subconscious to the traveler. Billed as romantic with great natural beauty, Thailand, the Philippines, Brazil, the Dominican Republic, and Kenya are popular destinations of tourists seeking sex. The Netherlands and countries in eastern Europe are also popular. With most initial cases of HIV infection in Europe having histories of international travel, mass tourism is a major factor in the international transmission of AIDS. While abroad, tourists have sex with casual partners, sex workers, and/or other tourists. Far from all tourists, however, carry and consistently use condoms with these partners. One study found female and non white travelers to be less likely than Whites and males to carry condoms. The risk of HIV infection increases in circumstances where condoms are not readily available in the host country and/or are of poor quality. Regarding actual condom use, a study found only 34% of sex tourists from Switzerland to consistently use condoms while abroad. 28% of men in an STD clinic in Melbourne, Australia, reported consistent condom use in sexual relations while traveling in Asia; STDs were identified in 73% of men examined. The few studies of tourists suggest that a significant proportion engage in risky behavior while traveling. HIV prevalence is rapidly increasing in countries known as destinations for sex tourism. High infection rates are especially evident among teenage sex workers in Thailand. Simply documenting the prevalence of risky behavior among sex tourists will not suffice. More research is needed on travelers and AIDS with particular attention upon the motivating factors supporting persistent high-risk behavior. PMID

  7. [AIDS information in Zimbabwe].

    Science.gov (United States)

    Meyer, L

    1993-11-20

    The difficulties of health education concerning AIDs prevention in Zimbabwe include communicating simple information about complicated processes, resistance to the information because of status or tradition, and lack of experience with translating material that was produced in the West. The beliefs in ghosts and witch doctors are still part of the tradition in Zimbabwe, providing cultural diversity and a sense of identification. Traditional medicine is characterized by Westerners as often irrational behavior that is deleterious to one's health. However, even in the allegedly educated part of the world compliance is often lacking and alternative treatment forms are actively pursued in tandem with formal medicine. When there is a short time period between harmful behavior and infection, most people realize that there is a causative connection. On the other hand, it is a more complicated mental exercise to fathom that intercourse can result in HIV infection that 5 years later may lead to death from tuberculosis. No other disease is known by these people that has a corresponding delay from the time of infection to disease or death. It is also confusing that a sexually transmitted disease does not produce symptoms such as discharge or genital sores. It is difficult to comprehend that a sole causative agent, HIV, can lead to so many different diseases and symptoms. When a young man died after having been hospitalized with protracted cough and TB as a result of HIV infection that he had contracted from a girlfriend, the father told the folks at home that his son had died of TB. These conflicting pieces of information make AIDS prevention education wrought with difficulties, which adds to the rapid spread of the disease, although the authorities and international organizations have responded with strategies, informational materials, and educational courses.

    Full Text Available Since the advent of human immunodeficiency virus infection, with its profound and progressive effect on the cellular immune system, a group of human opportunistic pathogens has come into prominence. Opportunistic parasitic infection can cause severe morbidity and mortality. Because many of these infections are treatable, an early and accurate diagnosis is important. This can be accomplished by a variety of methods such as direct demonstration of parasites and by serological tests to detect antigen and/or specific antibodies. However, antibody response may be poor in these patients and therefore immunodiagnostic tests have to be interpreted with caution. Cryptosporidium parvum , Isospora belli , Cyclospora cayetanensis , Microsporidia, Entamoeba histolytica and Strongyloides stercoralis are the commonly detected parasites. Detection of these parasites will help in proper management of these patients because drugs are available for most of these parasitic infections.

  14. Stepping toward a Macaque Model of HIV-1 Induced AIDS

    Directory of Open Access Journals (Sweden)

    Jason T. Kimata

    2014-09-01

    Full Text Available HIV-1 exhibits a narrow host range, hindering the development of a robust animal model of pathogenesis. Past studies have demonstrated that the restricted host range of HIV-1 may be largely due to the inability of the virus to antagonize and evade effector molecules of the interferon response in other species. They have also guided the engineering of HIV-1 clones that can replicate in CD4 T-cells of Asian macaque species. However, while replication of these viruses in macaque hosts is persistent, it has been limited and without progression to AIDS. In a new study, Hatziioannou et al., demonstrate for the first time that adapted macaque-tropic HIV-1 can persistently replicate at high levels in pigtailed macaques (Macaca nemestrina, but only if CD8 T-cells are depleted at the time of inoculation. The infection causes rapid disease and recapitulates several aspects of AIDS in humans. Additionally, the virus undergoes genetic changes to further escape innate immunity in association with disease progression. Here, the importance of these findings is discussed, as they relate to pathogenesis and model development.

  16. Pharmacological Inhibition of Feline Immunodeficiency Virus (FIV

    Directory of Open Access Journals (Sweden)

    Dorothee Bienzle

    2012-04-01

    Full Text Available Feline immunodeficiency virus (FIV is a member of the retroviridae family of viruses and causes an acquired immunodeficiency syndrome (AIDS in domestic and non-domestic cats worldwide. Genome organization of FIV and clinical characteristics of the disease caused by the virus are similar to those of human immunodeficiency virus (HIV. Both viruses infect T lymphocytes, monocytes and macrophages, and their replication cycle in infected cells is analogous. Due to marked similarity in genomic organization, virus structure, virus replication and disease pathogenesis of FIV and HIV, infection of cats with FIV is a useful tool to study and develop novel drugs and vaccines for HIV. Anti-retroviral drugs studied extensively in HIV infection have targeted different steps of the virus replication cycle: (1 inhibition of virus entry into susceptible cells at the level of attachment to host cell surface receptors and co-receptors; (2 inhibition of fusion of the virus membrane with the cell membrane; (3 blockade of reverse transcription of viral genomic RNA; (4 interruption of nuclear translocation and viral DNA integration into host genomes; (5 prevention of viral transcript processing and nuclear export; and (6 inhibition of virion assembly and maturation. Despite much success of anti-retroviral therapy slowing disease progression in people, similar therapy has not been thoroughly investigated in cats. In this article we review current pharmacological approaches and novel targets for anti-lentiviral therapy, and critically assess potentially suitable applications against FIV infection in cats.

    2015-06-01

    In recent years plant viruses have been detected from many environments, including domestic and wild plants and interfaces between these systems-aquatic sources, feces of various animals, and insects. A variety of methods have been employed to study plant virus biodiversity, including enrichment for virus-like particles or virus-specific RNA or DNA, or the extraction of total nucleic acids, followed by next-generation deep sequencing and bioinformatic analyses. All of the methods have some shortcomings, but taken together these studies reveal our surprising lack of knowledge about plant viruses and point to the need for more comprehensive studies. In addition, many new viruses have been discovered, with most virus infections in wild plants appearing asymptomatic, suggesting that virus disease may be a byproduct of domestication. For plant pathologists these studies are providing useful tools to detect viruses, and perhaps to predict future problems that could threaten cultivated plants.

    2003-04-01

    This presentation reviews hearing-aid development from analog to advanced digital technology. A basic hearing aid consists of a microphone, an amplification circuit that provides a gain that varies with frequency to accommodate variations in hearing loss with frequency, and a small earphone. In recent years, hearing aid technology has developed rapidly. Digital hearing aids have become commonplace and their share of the marketplace is increasing rapidly. Therefore, the main focus of this talk is signal-processing schemes in advanced digital hearing aids, including microphones with digitally controlled directional characteristics, wide-dynamic-range compression in multiple channels that allow the compression characteristics to vary with frequency, noise reduction, and feedback cancellation. Each of these signal-processing functions help address the needs of individuals with hearing losses.

    Yugo, Danielle M; Hauck, Ruediger; Shivaprasad, H L; Meng, Xiang-Jin

    2016-09-01

    Viral hepatitis in poultry is a complex disease syndrome caused by several viruses belonging to different families including avian hepatitis E virus (HEV), duck hepatitis B virus (DHBV), duck hepatitis A virus (DHAV-1, -2, -3), duck hepatitis virus Types 2 and 3, fowl adenoviruses (FAdV), and turkey hepatitis virus (THV). While these hepatitis viruses share the same target organ, the liver, they each possess unique clinical and biological features. In this article, we aim to review the common and unique features of major poultry hepatitis viruses in an effort to identify the knowledge gaps and aid the prevention and control of poultry viral hepatitis. Avian HEV is an Orthohepevirus B in the family Hepeviridae that naturally infects chickens and consists of three distinct genotypes worldwide. Avian HEV is associated with hepatitis-splenomegaly syndrome or big liver and spleen disease in chickens, although the majority of the infected birds are subclinical. Avihepadnaviruses in the family of Hepadnaviridae have been isolated from ducks, snow geese, white storks, grey herons, cranes, and parrots. DHBV evolved with the host as a noncytopathic form without clinical signs and rarely progressed to chronicity. The outcome for DHBV infection varies by the host's ability to elicit an immune response and is dose and age dependent in ducks, thus mimicking the pathogenesis of human hepatitis B virus (HBV) infections and providing an excellent animal model for human HBV. DHAV is a picornavirus that causes a highly contagious virus infection in ducks with up to 100% flock mortality in ducklings under 6 wk of age, while older birds remain unaffected. The high morbidity and mortality has an economic impact on intensive duck production farming. Duck hepatitis virus Types 2 and 3 are astroviruses in the family of Astroviridae with similarity phylogenetically to turkey astroviruses, implicating the potential for cross-species infections between strains. Duck astrovirus (DAstV) causes

  13. Nuclear medicine and AIDS

    International Nuclear Information System (INIS)

    The human immunodeficiency virus (HIV) infection and its associated illnesses in a relatively young population of patients provides an expanding role for nuclear medicine. The disease enforces a review of each department's infection control procedures. It has also resulted in an increase in the number of patients presenting with diseases such as Pneumocystis carinii pneumonia, Kaposi's sarcoma etc. which prior to the HIV epidemic were extremely rare. Thus in high risk patients the interpretation of abnormalities in nuclear medicine scans needs to include the spectrum of opportunistic infections and unusual tumours. The presence of opportunistic infections in the severely immunocompromised patient has led to the development of techniques not normally used, i.e. lung 99Tcm-diethylenetriamine pentaacetate (DTPA) transfer/clearance, donor leukocyte scanning to allow rapid diagnosis of an abnormality. Radionuclide techniques are also used to monitor the effect of therapy directed at the HIV itself or against opportunistic infections. This review covers aspects of infection control as well as the use of radionuclides to investigate specific problems related to HIV infection and therapy of the associated disease processes.

    Science.gov (United States)

    Yang, Lu-Xing; Yang, Xiaofan

    2014-06-01

    This paper addresses the epidemiological modeling of computer viruses. By incorporating the effect of removable storage media, considering the possibility of connecting infected computers to the Internet, and removing the conservative restriction on the total number of computers connected to the Internet, a new epidemic model is proposed. Unlike most previous models, the proposed model has no virus-free equilibrium and has a unique endemic equilibrium. With the aid of the theory of asymptotically autonomous systems as well as the generalized Poincare-Bendixson theorem, the endemic equilibrium is shown to be globally asymptotically stable. By analyzing the influence of different system parameters on the steady number of infected computers, a collection of policies is recommended to prohibit the virus prevalence.

  15. Alaska Dental Health Aide Program

    Full Text Available Background. In 1999, An Oral Health Survey of American Indian and Alaska Native (AI/AN Dental Patients found that 79% of 2- to 5-year-olds had a history of tooth decay. The Alaska Native Tribal Health Consortium in collaboration with Alaska’s Tribal Health Organizations (THO developed a new and diverse dental workforce model to address AI/AN oral health disparities. Objectives. This paper describes the workforce model and some experience to date of the Dental Health Aide (DHA Initiative that was introduced under the federally sanctioned Community Health Aide Program in Alaska. These new dental team members work with THO dentists and hygienists to provide education, prevention and basic restorative services in a culturally appropriate manner. Results. The DHA Initiative introduced 4 new dental provider types to Alaska: the Primary Dental Health Aide, the Expanded Function Dental Health Aide, the Dental Health Aide Hygienist and the Dental Health Aide Therapist. The scope of practice between the 4 different DHA providers varies vastly along with the required training and education requirements. DHAs are certified, not licensed, providers. Recertification occurs every 2 years and requires the completion of 24 hours of continuing education and continual competency evaluation. Conclusions. Dental Health Aides provide evidence-based prevention programs and dental care that improve access to oral health care and help address well-documented oral health disparities.

  19. AIDS. Grim news for Asia.

    Science.gov (United States)

    1992-12-01

    While Asia was the last region to be exposed to the global spread of HIV and AIDS, the incidence of HIV infection there is increasing fastest. The Asian Development Bank predicts mortality from AIDS will cause some town and village populations to begin declining by the year 2000. With an estimated 1 million people infected in India, and 400,000 in Thailand, these 2 countries are particularly exposed to the risk of epidemic HIV spread. In 5 years, more people may be affected by AIDS in India than anywhere else in the world. Concern over a growing presence of HIV is also merited for the Philippines, Indonesia, China, and the drug trade's Golden Triangle. The Second International Conference on AIDS in Asia and the Pacific in November 1992 stressed that AIDS no longer affects only homosexual and IV drug using populations. 50% of new infections worldwide in the first half of 1992 were among women, 65% of Thailand's AIDS cases are among heterosexuals, and 3-5% of Thailand's long-haul truck drivers have tested positive for HIV infection. HIV and AIDS robs economies and societies of their best workers. The immediate costs of caring for AIDS patients will pale next to the far greater losses to be realized in private sector economic productivity. Asia's more developed economies will probably be able to survive the epidemic, but small, poor countries like Laos will wilt. Prompt action must be taken to overcome public and religious ignorance and objections to promoting and using condoms throughout the region. For the first time, Beijing has organized an AIDS awareness conference for male homosexuals. Further, Singapore has implemented compulsory testing for lower-income foreign workers. Pakistan has even solicited educational assistance and support from Islamic religious leaders; similar action is being considered in Bangladesh.

  20. Reprieve for Thailand's AIDS campaign.

    Science.gov (United States)

    Clements, A

    1992-07-25

    A promilitary coalition began to govern Thailand in March 1992. It reduced the budget for the original proposed national AIDS awareness campaign from 30 million British pounds to almost 15 million British pounds. The Ministry of Health professed that the campaign had exaggerated the problem of AIDS in Thailand and had damaged tourism. Yet prodemocracy demonstrations in Bangkok in which troops killed many protesters restored the politicians who started the AIDS campaign to power in May 1992. There were to remain in power until new elections in September 1992. In July, the Minister of Health, Mechai Viravaidya, said he would step down if the government did not completely restore the 30 million British pounds for the AIDS campaign. It then increased the budget to almost that amount. Mr. Viravaidya initiated Thailand's open policy on the AIDS crisis and was known as Mr. Condom. He claimed that at the present HIV prevalence rate, Thailand may have between 2-4 million HIV infected people by 2000. If the country would take on anti-AIDS efforts now, however, they could cut the spread of HIV by 75%. As of mid-1992, about 400,000 people living in Thailand were HIV positive. The AIDS campaign planned to sue the mass media to inform people about AIDS especially those in universities and schools and high risk occupational groups. The increasing number of construction workers in Bangkok and existing sex workers were a high risk occupational group. At the 2nd national seminar of AIDS, the Minister of Health reproached tourists who come to Thailand for its sex industry. He said that Thailand does not need the 1 billion British pounds they bring to Thailand annually, and Thais do not want their homeland to be referred to as the sex capital.

In this study, individuals and groups of survivors of life-threatening events were debriefed and the behavior of those who coped well during such a threat to life were compared with those who did not. The behaviors of those who coped well were distilled into a set of principles for psychological first aid; that is, a series of simple actions for use within a disaster which serves to recover victims to functional behavior as quickly as possible, thus increasing their chance for survival. These principles of psychological first aid have recently been introduced into basic first aid and survival training courses for both military and civilian units.

    1994-05-01

    A field test combined participatory evaluation methods with more traditional techniques to assess the progress of The AIDS Service Organization (TASO) Community Initiatives program in Uganda to encourage greater community involvement in improving the program. Approximately 1.5 million people in Uganda are infected with the HIV virus. Estimated HIV prevalence ranges from 25 to 30% in the capital city of Kampala and is as high as 50% in some trading centers along the main highway, but as low as 1% in some rural areas. To empower people within their own communities to prevent the further spread of HIV and better support people with AIDS, TASO launched The Community Initiatives program in 1990. Under this program, TASO trainers help community leaders form a village AIDS committee and identify community needs and objectives. Local leaders then select community AIDS workers, who receive training from TASO in AIDS prevention, education, counseling, and care. These community volunteers conduct formal and informal educational sessions with groups and individuals, visit homes to provide counseling and assistance with care, distribute condoms, and refer people for HIV testing and medical treatment. During 1993 an evaluation plan in 2 of the 17 TCI-supported communities was field tested. The primary data collection methods were a knowledge, attitudes, and practices survey, followed by focus group discussions, and individual interviews with key informants. Several participatory methods also involved community members in data collection, analysis, and interpretation. More than 300 people gathered in the trading center of Biharwe to comment on the evaluation results from a community-based AIDS program. Through this process of encouraging audience participation and eliciting feedback, the evaluation sessions armed the work of the community implementors, disseminated more knowledge about changing sexual norms, and fostered greater community support for the program.

  3. Alterations in HIV-1 LTR promoter activity during AIDS progression

    International Nuclear Information System (INIS)

    HIV-1 variants evolving in AIDS patients frequently show increased replicative capacity compared to those present during early asymptomatic infection. It is known that late stage HIV-1 variants often show an expanded coreceptor tropism and altered Nef function. In the present study we investigated whether enhanced HIV-1 LTR promoter activity might also evolve during disease progression. Our results demonstrate increased LTR promoter activity after AIDS progression in 3 of 12 HIV-1-infected individuals studied. Further analysis revealed that multiple alterations in the U3 core-enhancer and in the transactivation-response (TAR) region seem to be responsible for the enhanced functional activity. Our findings show that in a subset of HIV-1-infected individuals enhanced LTR transcription contributes to the increased replicative potential of late stage virus isolates and might accelerate disease progression

    Full Text Available Mucosal immunity consists of innate and adaptive immune responses which can be influenced by systemic immunity. Despite having been the subject of intensive studies, it is not fully elucidated what exactly occurs after HIV contact with the female genital tract mucosa. The sexual route is the main route of HIV transmission, with an increased risk of infection in women compared to men. Several characteristics of the female genital tract make it suitable for inoculation, establishment of infection, and systemic spread of the virus, which causes local changes that may favor the development of infections by other pathogens, often called sexually transmitted diseases (STDs. The relationship of these STDs with HIV infection has been widely studied. Here we review the characteristics of mucosal immunity of the female genital tract, its alterations due to HIV/AIDS, and the characteristics of coinfections between HIV/AIDS and the most prevalent STDs.

    Siegel, K; Raveis, V H

    1993-01-01

    Since it was first recognized that human immunodeficiency virus (HIV) infection could be sexually transmitted, celibacy has been advocated by some as the only unequivocally effective adaptation for avoiding the risk of infection. Others, however, have countered that few will be willing to be celibate and, further, that such behavior may have adverse psychosocial consequences. As part of a qualitative study of gay men's sexual decision-making in the context of the AIDS/HIV epidemic, we identified a subsample of respondents who had adopted celibacy for varying periods of time as an adaptation to the threat of AIDS/HIV infection. A content analysis of these men's interviews revealed 5 principal themes relating their reasons for choosing celibacy. PMID:8297710

    This study uses Goffman's [1963. Stigma: Notes on the Management of Spoiled Identity, New Jersey, Prentice-Hall] theory of stigma as an intellectual scaffold to help understand the social meaning of HIV/AIDS stigma from People Living with HIV/AIDS. The study adopts a qualitative approach because of its appropriateness for unravelling subjective phenomena such as the experiences of HIV/AIDS stigma. In-depth interviews were conducted with 10 HIV-positive employees of a retailing company located in the Western Cape province of South Africa who volunteered to participate in the study. The participants with the discreditable stigma internalised society's prejudice towards those living with the virus. As a result, the participants relied on self-isolation and social withdrawal to cope with enacted stigma. Managing information about one's status and deciding whether, who, when, etc., to tell are crucial questions. The participants feared being devalued by family, friends, co-workers and the community. In concurrence with Goffman [1963], the HIV/AIDS stigma is seen as about relationships.

    2005-01-01

    After nearly three decades of being virtually drug free, use of heroin and other illicit drugs has re-emerged in China as a major public health problem. One result is that drug abuse, particularly heroin injection, has come to play a predominant role in fueling China's AIDS epidemic. The first outbreak of HIV among China's IDUs was reported in the border area of Yunnan province between China and Myanmar where drug trafficking is heavy. Since then drug-related HIV has spread to all 31 provinces, autonomous regions and municipalities. This paper provides an overview to HIV/AIDS transmission through injection drug use in China. It begins with a brief history of the illicit drug trade in China, followed by a discussion of the emergence of drug related AIDS, and a profile of drug users and their sexual partners who have contracted the virus or who are vulnerable to infection. It ends by summarizing three national strategies being used by China to address both drug use and AIDS as major health threats.

    The New York Blood Center is developing a health education and psychosocial support program for blood donors who are notified that they are HIV antibody positive. The goals of that program are: to provide accurate and intelligible information about the test results to notified donors; to encourage behavior that will reduce the likelihood of spreading the virus; to encourage notified donors to behave in ways that will reduce the probability that they will develop AIDS; and to provide support and facilitate functional coping responses. This article reviews the theoretical and empirical work which informs the intervention program, and it describes how the program is being implemented. PMID:3023260

    Full Text Available Abstract HIV (Human Immunodeficiency virus causes (acquired immunodeficiency syndrome AIDS, in which the immune system of body totally fails to develop any defense against the foreign invaders. Infection with HIV occurs by transfer of blood, semen, and breast milk. HIV/AIDS is a global problem and it results nearly 25 million deaths worldwide. Developing countries like Pakistan have issues regarding Public Health. Currently, epidemic of HIV/AIDS is established in Pakistan and there is a threat of an expanded HIV/AIDS outbreak in the country. The major reason is that population is engaging in high-risk practices, low awareness about HIV/AIDS, and treacherous blood transfusion practices. A supplementary threat to Pakistan is India because both sharing a border and India is facing a rapidly growing HIV/AIDS epidemic. Local NGOs, National and International organizations are warning that in near future Pakistan may experiences bad situation regarding HIV/AIDS. In the present article we focused current situation of surveillance of HIV/AIDS, its virology, genotype, diagnostics, high-risk groups, reasons of vulnerability in Pakistani population, and the role of different national and international organizations in this situation.

  19. Detection and diagnosis of rice-infecting viruses

    2013-10-01

    Full Text Available Rice-infecting viruses have caused serious damage to rice production in Asian, American, and African countries, where about 30 rice viruses and diseases have been reported. To control these diseases, developing accurate, quick methods to detect and diagnose the viruses in the host plants and any insect vectors of the viruses is very important. Based on an antigen–antibody reaction, serological methods such as latex agglutination reaction (LAR and enzyme-linked immunosorbent assay (ELISA have advanced to detect viral particles or major proteins derived from viruses. They aid in forecasting disease and surveying disease spread and are widely used for virus detection at plant protection stations and research laboratories. From the early 2000s, based on sequence information for the target virus, several other methods such as reverse transcription-polymerase chain reaction (RT-PCR and reverse transcription- loop-mediated isothermal amplification (RT-LAMP have been developed that are sensitive, rapid, and able to differentiate closely related viruses. Recent techniques such as real-time RT-PCR can be used to quantify the pathogen in target samples and monitor population dynamics of a virus, and metagenomic analyses using next-generation sequencing and microarrays show potential for use in the diagnosis of rice diseases.

  20. TGF-β suppression of HBV RNA through AID-dependent recruitment of an RNA exosome complex.

    Directory of Open Access Journals (Sweden)

    Guoxin Liang

    2015-04-01

    Full Text Available Transforming growth factor (TGF-β inhibits hepatitis B virus (HBV replication although the intracellular effectors involved are not determined. Here, we report that reduction of HBV transcripts by TGF-β is dependent on AID expression, which significantly decreases both HBV transcripts and viral DNA, resulting in inhibition of viral replication. Immunoprecipitation reveals that AID physically associates with viral P protein that binds to specific virus RNA sequence called epsilon. AID also binds to an RNA degradation complex (RNA exosome proteins, indicating that AID, RNA exosome, and P protein form an RNP complex. Suppression of HBV transcripts by TGF-β was abrogated by depletion of either AID or RNA exosome components, suggesting that AID and the RNA exosome involve in TGF-β mediated suppression of HBV RNA. Moreover, AID-mediated HBV reduction does not occur when P protein is disrupted or when viral transcription is inhibited. These results suggest that induced expression of AID by TGF-β causes recruitment of the RNA exosome to viral RNP complex and the RNA exosome degrades HBV RNA in a transcription-coupled manner.

    Full Text Available Rehabilitation of deaf individual is one of the important subjects that has attracted attention of many researchers during past centuries. Different opinions have been established in this direction. Electrophysiologic tests were established and developed parallel to developments in rehabilitation. Therefore, opinion of using electrophysiologic test for evaluation and fitting of hearing aid became gradually popular. Ultimately, the electrophysiologic tests are used in evaluation and fitting of hearing aid in two ways: 1-Direct way 2- Indirect way "nIn direct way aided ABR is obtained and special attention is paid to wave V. This technique has many difficulties. Inindirect way, electrophysiologic tests such, ECochG, OAE and ABR, AMLR, ALR and P300 and other objective tests are used, especially in infants and neonates for evaluating the state of hearing. Researches are continuing in this field. It is probable to have aided electrophysiologic responses with speech stimuli in near future.

  11. Magnetic resonance imaging findings of the brain in adult HIV and AIDS patients

    International Nuclear Information System (INIS)

    The spectrum of pathology affecting the central nervous system (CNS) in patients suffering from acquired immunodeficiency syndrome (AIDS) includes not only the human immunodeficiency virus (HIV) infection itself but also opportunistic infections and tumors secondary to AIDS. Despite progress in antiretroviral therapy and the subsequent decrease in the incidence of associated diseases, opportunistic infections and tumors secondary to the HIV infection continue to be the limiting factor in terms of survival with AIDS. Therefore, the therapeutic aim is permanent antiretroviral therapy as well as early diagnosis and treatment of opportunistic infections. Magnetic resonance imaging is often the diagnostic method of choice in suspected CNS pathology of HIV patients. In the following, the typical clinical and radiological features of several AIDS-related pathologies are presented and discussed. (orig.)

    Full Text Available The rapid emergence of AIDS in humans during the period between 1980 and 2000 has led to extensive efforts to understand more fully similar etiologic agents of chronic and progressive acquired immunodeficiency disease in several mammalian species. Lentiviruses that have gene sequence homology with human immunodeficiency virus (HIV have been found in different species (including sheep, goats, horses, cattle, cats, and several Old World monkey species. Lentiviruses, comprising a genus of the Retroviridae family, cause persistent infection that can lead to varying degrees of morbidity and mortality depending on the virus and the host species involved. Feline immunodeficiency virus (FIV causes an immune system disease in domestic cats (Felis catus involving depletion of the CD4+ population of T lymphocytes, increased susceptibility to opportunistic infections, and sometimes death. Viruses related to domestic cat FIV occur also in a variety of nondomestic felids. This is a brief overview of the current state of knowledge of this large and ancient group of viruses (FIVs in South America.

The patients carried a wide range of clinical diagnosis including Reiter syndrome, psoriatic arthritis, undifferentiated seronegative arthritis, isolated enthesopathies, rheumatoid arthritis and osteonecrosis. Radiographs were available in 24 of the 31 patients, and in 20 they showed radiographic features of arthritis, which included soft-tissue swelling periarticular osteoporosis, synovial effusions, sacroiliitis, periosteal reaction, joint space narrowing, marginal erosions, and osteonecrosis. Although the radiographic abnormalities were frequently mild, they were significant, given the short duration of disease in many of their patients (weeks to months) at the time radiographs were obtained. The range of radiographic findings in their series was varied and paralleled the wide range of clinical diagnoses. No findings were pathognomonic for HIV-associated arthritis. Nevertheless, HIV infection needs to be considered in any patient belonging to a recognized risk group who presents with musculoskeletal disease. This is particularly important since immunosupressive drugs used for the treatment of arthritis can be detrimental to patients with HIV infection

    The appearance of the Acquired Immune Deficiency Syndrome (AIDS) meant a revolution in medicine, which has also affected Ophthalmology: the routine presence of ophthalmological pathologies which until then had been exceptional, such as retinitis due to cytomegalovirus (CMV), and the appearance of other new pathologies such as progressive outer retinal necrosis (PORN). The generalised use of high activity antiretroviral therapy (HAART) in the second half of the 1990s represented a turning point, since when the immunological improvement of patients with Human Immunodeficiency Virus (HIV) resulted in a fall in the cases with ophthalmological pathology associated to immunodepression (HIV retinopathy, retinitis due to CMV, PORN...), and the spontaneous improvement of symptoms which until then had had a torpid evolution (Kaposi's ocular sarcoma, Palpebral Molluscum...). On the other hand, the continuous increase in the prevalence of syphilis in these patients means an increase in the number of cases of ocular syphilis unassociated with immunodepression. New ophthalmological alterations also appear that are related to HAART: uveitis due to immune recovery in patients with CMV retinitis in complete remission and the enophthalmos due to the atrophy of orbital fat in the context of lipodystrophy, associated with antiretrovirals. At present preventive ophthalmological checks must be carried out on patients with severe immunodepression until a count of lymphocytes above 100 cells/microl is confirmed. If they also show HIV retinopathy, a monthly check up is advisable until immune recovery, given the greater risk of infection by CMV. PMID:19169296

    Full Text Available Studies on the social management of HIV and AIDS have focused on how awareness about HIV and AIDS has been created through organised and interpersonal communication. These studies have not investigated context-constrained language use in the advertisements on the disease despite the wide coverage and potential effectiveness of the public sensitisation about HIV and AIDS. This study, therefore, investigated the pragmatic features of language in selected HIV and AIDS management advertisements with a view to identifying the pragmatic acts of the language. Aspects of pragmatic act theory, noted for negotiability of meaning context based interactional situations was adopted for the research. All the 25 advertisements broadcast between December 2006 and June 2009, to all African countries on both private and government-owned television stations in Nigeria by an International non-governmental agency known as 'it begins with you' (YOU constituted the data. Fifty–four utterances were generated from the adverts and were subjected to qualitative analysis and reported in simple percentages. Six pragmatic functions manifested in the advertisements: Co-opting and Projecting were realised through inference (INF, shared situational knowledge (SSK and relevance (REL to bring the audience into the war against HIV/AIDS. Encouraging and Emboldening were projected through SSK and INF to motivate the audience to go for HIV test and speak openly about the virus. Instigating was done using indirect speech act to empower the female against discrimination and stigmatisation. Advising was achieved through SSK and INF to promote fidelity and safe sexual behaviour. The analysis of YOU advertisements through pragmatic act theory presupposes that pragmatic functions were exploited by the advertisers to sensitise the audience, promote social ties and project into an HIV free generation.

    With a view to ensuring optimum use of the first-aid boxes on the CERN site, we should like to remind you of various changes introduced in March 2009: The TSO of the buildings concerned is responsible for the first-aid boxes, including checking their contents.   First-aid boxes may be restocked ONLY at the CERN stores (SCEM No. 54.99.80). This is no longer possible at the Infirmary. The associated cost is charged to the Departments.   First-aid boxes should be used only for mild injuries. All other cases should be referred to the Medical Service Infirmary (Bldg. 57 – ground-floor, tel. 73802) between 8.00 a.m. and 5.30 p.m. or to the Fire and Rescue Service (tel. 74444). N.B.: This information does not apply to the red emergency first-aid boxes in the underground areas or to the emergency kits for use in the event of being splashed with hydrofluoric acid.

    The Acquired Immune Deficiency Syndrome (AIDS) distribution program in Brazil, spearheaded by the National Division of Sanitary Surveillance in Ports, Airports, and Borders, was part of the government's massive education campaign to prevent the transmission of HIV-AIDS in Brazil. Beginning in February 1987, the climate was sufficiently favorable to operate a coordinated information campaign during the Carnival celebration, and tourists arriving in the cities of Brazil for the annual Carnival celebration were handed an educational brochure in Portugese, Spanish, English, and French. Yet, beyond reaching the tourist populations, it is particularly important to reach large portions of the Brazilian population. Planners of the national AIDS campaign intend to use television, radio, and all major newspapers in their effort to cover the country. Initial television coverage is comprised of short informational messages directed at high-risk groups. There also are plans to use radio and the print media in order to reach a wider audience. It is estimated that US $6 million will be needed to adequately meet the costs of AIDS prevention and medical care, but due to extreme budget constraints, only $45,000 has been earmarked for ongoing AIDS activities at this time.

    Full Text Available Embora não esteja definitivamente comprovada que a severidade da malária esteja associada com o vírus da imunodeficiência humana (HIV, sabe-se que a infecção pelo Plasmodium falciparum pode favorecer uma rápida evolução da infecção pelo HIV. Além disso a associação da malária com HIV/AIDS, do ponto de vista clínico, pode ser extremamente grave face a ocorrência de outros microorganismos e/ou neoplasias, o que piora a evolução e prognóstico dos pacientes. A concomitância do vírus HIV com o Plasmodium em zonas endêmicas de malária, é uma possibilidade que deve ser sempre pensada, visto que a sua transmissão está relacionada a fatores de risco ligados aos comportamentos das pessoas, que nem sempre são logo revelados e/ou identificados. Os autores descrevem um caso de malária cerebral por Plasmodium vivaxe Plasmodiumfalciparum em um paciente com AIDS. Descrevem sua evolução clínica e terapêutica.Although it has not been definitely proven that the severity of malaria is associated to human immunodeficiency virus (HIV we know that infection through Plasmodium falciparum can favor a rapid evolution of the HIV infection. Besides, association of malaria with HIV/AIDS from a clinical point of view can be clinically severe in the face of the occurrence of other microorganisms or neoplasias, which worsens the evolution and prognosis of the affected patients. The concurrence of HIV with Plasmodium in malaria endemic zones is a possibility which should always be taken into consideration, since transmission is related to risk factors caused by people's behavior which are not always promptly revealed and/or identified. The authors report one case of brain malaria infection by Plasmodium vivax and Plasmodium falciparum in a patient with AIDS. They describe the clinical evolution and therapy.

  10. Viruses Infecting Reptiles

    Directory of Open Access Journals (Sweden)

    Rachel E. Marschang

    2011-11-01

    Full Text Available A large number of viruses have been described in many different reptiles. These viruses include arboviruses that primarily infect mammals or birds as well as viruses that are specific for reptiles. Interest in arboviruses infecting reptiles has mainly focused on the role reptiles may play in the epidemiology of these viruses, especially over winter. Interest in reptile specific viruses has concentrated on both their importance for reptile medicine as well as virus taxonomy and evolution. The impact of many viral infections on reptile health is not known. Koch’s postulates have only been fulfilled for a limited number of reptilian viruses. As diagnostic testing becomes more sensitive, multiple infections with various viruses and other infectious agents are also being detected. In most cases the interactions between these different agents are not known. This review provides an update on viruses described in reptiles, the animal species in which they have been detected, and what is known about their taxonomic positions.

    Background Aquired immune deficiency syndrome (AIDS) presents a challenge to medical researchers because of its unique pathological and clinical picture. The clinical data, particularly autopsy evidence, from China have failed to provide enough pathological and etiological evidence for AIDS diagnosis, which impairs the reliability of the diagnosis and our full understanding of the occurrence and development of AIDS complications. The purpose of this study was to investigate the imaging and pathologic characteristics of AIDS.Methods Autopsy, imaging and pathological data from 8 cases of AIDS were retrospectively analyzed. Routine CT scanning of different body parts was performed during their periods of hospitalization. Transverse CT scanning was conducted from the skull to the pelvis immediately after the occurrence of death. After routine formalin fixing, 7 cardevers were cross sectioned for autopsy in freezing state and 1 for gross autopsy. Tissues were obtained from each section and organs for pathological examinations.Results The autopsy data indicated the presence of parasitic infections, bacterial infections, fungal infections, and virus infections in AIDS patients. Pneumocystis pneumonia, pulmonary tuberculosis, coccobacteria pneumonia, Aspergillus pneumonia, cytomegalovirus pneumonia, toxoplasma encephalitis, lymphoma and cerebrovascular diseases were found in these patients.Conclusions During the course of AIDS progression, the concurrent multiple infections as well as tumor development may result in multiple organ pathological changes and clinically complex symptoms that further complicate the imaging and pathological manifestations, thus resulting in difficult differential diagnosis. A combination of imaging data and autopsy data can help to clarify the diagnosis.

    AIDS as a new lethal and at present incurable sexually transmitted disease is already having remarkable social repercussions not yet fully explicit and hence it can be termed a social phenomenon. Political, behavioural, economic and legal reactions and social responses such as stigmatization, changes in the sick role and the growth of voluntary organizations and international collaboration are described. Communication, education and information aspects of AIDS are considered using material from the press and it is clear that a massive educational approach to modify behaviour must be the basis for a control programme.

  3. Spinal tract pathology in AIDS: postmortem MRI correlation with neuropathology

    International Nuclear Information System (INIS)

    Vacuolar myelopathy (VM) and tract pallor are poorly understood spinal tract abnormalities in patients with the acquired immunodeficiency syndrome (AIDS). We studied the ability of magnetic resonance imaging (MRI) to detect these changes in spinal cord specimens postmortem and whether criteria could be formulated which would allow these conditions to be differentiated from other lesions of the spinal cord in AIDS, such as lymphoma, cytomegalovirus (CMV) and human immunodeficiency virus (HIV) myelitis. We imaged 38 postmortem specimens of spinal cord. The MRI studies were interpreted blind. The specimens included cases of VM myelin pallor. CMV myeloradiculitis, HIV myelitis, lymphoma as well as normal cords, both HIV+ve and HIV-ve. MRI showed abnormal signal, suggestive of tract pathology, in 10 of the 14 cases with histopathological evidence of tract changes. The findings in VM and tract pallor on proton-density and T2-weighted MRI were increased signal from the affected white-matter tracts, present on multiple contiguous slices and symmetrical in most cases. The pattern was sufficiently distinct to differentiate spinal tract pathology from other spinal cord lesions in AIDS. (orig.)

    Human immunodeficiency virus (HIV) infection remains of major public health importance in Europe, with evidence of increasing transmission of HIV in several countries. This article provides an overview of HIV and acquired immunodeficiency syndrome (AIDS) surveillance data, and indicates that since 2000 the rate of newly reported cases of HIV per million population has almost doubled in Europe. In 2007, a total of 48,892 cases of HIV infection were reported from 49 of 53 countries in the Region, with the highest rates in Estonia, Ukraine, Portugal and the Republic of Moldova. In the European Union (EU) and European Free Trade Association (EFTA) countries, the predominant mode of transmission for HIV infection is sex between men followed by heterosexual contact. Injecting drug use is still the main mode of transmission in the eastern part of the WHO European region, while in the central part heterosexual contact is the predominant mode of transmission. In 2007, the reported number of AIDS cases diagnosed decreased in the Region overall, except in the eastern part. HIV/AIDS surveillance data are vital to monitor the trends of the HIV epidemic and evaluate public health responses. PMID:19087870

  5. Plant Viruses as Nanoparticle-Based Vaccines and Adjuvants

    Directory of Open Access Journals (Sweden)

    Marie-Ève Lebel

    2015-08-01

    Full Text Available Vaccines are considered one of the greatest medical achievements in the battle against infectious diseases. However, the intractability of various diseases such as hepatitis C, HIV/AIDS, malaria, tuberculosis, and cancer poses persistent hurdles given that traditional vaccine-development methods have proven to be ineffective; as such, these challenges have driven the emergence of novel vaccine design approaches. In this regard, much effort has been put into the development of new safe adjuvants and vaccine platforms. Of particular interest, the utilization of plant virus-like nanoparticles and recombinant plant viruses has gained increasing significance as an effective tool in the development of novel vaccines against infectious diseases and cancer. The present review summarizes recent advances in the use of plant viruses as nanoparticle-based vaccines and adjuvants and their mechanism of action. Harnessing plant-virus immunogenic properties will enable the design of novel, safe, and efficacious prophylactic and therapeutic vaccines against disease.

    Full Text Available In HIV infection, TLR7-triggered IFN-α production exerts a direct antiviral effect through the inhibition of viral replication, but may also be involved in immune pathogenesis leading to AIDS. TLR7 could also be an important mediator of vaccine efficacy. In this study, we analyzed polymorphisms in the X-linked TLR7 gene in the rhesus macaque model of AIDS. Upon resequencing of the TLR7 gene in 36 rhesus macaques of Indian origin, 12 polymorphic sites were detected. Next, we identified three tightly linked single nucleotide polymorphisms (SNP as being associated with survival time. Genotyping of 119 untreated, simian immunodeficiency virus (SIV-infected male rhesus macaques, including an 'MHC adjusted' subset, revealed that the three TLR7 SNPs are also significantly associated with set-point viral load. Surprisingly, this effect was not observed in 72 immunized SIV-infected male monkeys. We hypothesize (i that SNP c.13G>A in the leader peptide is causative for the observed genotype-phenotype association and that (ii the underlying mechanism is related to RNA secondary structure formation. Therefore, we investigated a fourth SNP (c.-17C>T, located 17 bp upstream of the ATG translation initiation codon, that is also potentially capable of influencing RNA structure. In c.13A carriers, neither set-point viral load nor survival time were related to the c.-17C>T genotype. In c.13G carriers, by contrast, the c.-17C allele was significantly associated with prolonged survival. Again, no such association was detected among immunized SIV-infected macaques. Our results highlight the dual role of TLR7 in immunodeficiency virus infection and vaccination and imply that it may be important to control human AIDS vaccine trials, not only for MHC genotype, but also for TLR7 genotype.

    Full Text Available Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidence for such a role has been elusive. However, the development of extremely sophisticated new experimental techniques has allowed the recent development of evidence that human papilloma virus, Epstein-Barr virus, mouse mammary tumor virus and bovine leukemia virus may each have a role in the causation of human breast cancers. This is potentially good news as effective vaccines are already available to prevent infections from carcinogenic strains of human papilloma virus, which causes cancer of the uterine cervix.

    1989-01-01

    The eighth volume of Advances in Viral Oncology focuses on the three major DNA virus groups with a postulated or proven tumorigenic potential: papillomaviruses, animal hepatitis viruses, and the Epstein-Bar virus. In the opening chapters, the contributors analyze the evidence that papillomaviruses and animal hepatitis viruses are involved in tumorigenesis and describe the mechanisms that trigger virus-host cell interactions. A detailed section on the Epstein-Barr virus (EBV) - comprising more than half the book - examines the transcription and mRNA processing patterns of the virus genome; the mechanisms by which EBV infects lymphoid and epithelial cells; the immunological aspects of the virus; the actions of EBV in hosts with Acquired Immune Deficiency Syndrome; and the involvement of EBV in the etiology of Burkitt's lymphoma.

Since the establishment of such systems for influenza virus, numerous attempts have been made to tame this pathogenic agent. In particular, several types of viruses expressing foreign genes have been generated and used to further our knowledge of influenza virus replication and pathogenicity and to develop novel influenza vaccines. Here, we review these achievements and discuss ...

  7. Immunophototherapy for the treatment of AIDS and AIDS-related infections

    1992-06-01

    Immunophototherapy (IPT) is an experimental method of medical treatment that seeks to provide for the selective destruction of diseased cells and microbes such as human immunodeficiency virus (HIV)-T4 cells and the rapid elimination of their toxic by-products from the human body. Photosensitive monoclonal or polyclonal antibody fragments, which are specific to the diseased cell or microbe, will be used to treat acquired immunodeficiency syndrome (AIDS) and related infections. These antibody fragments are tagged with photosensitive compounds and metal colloids and then intravenously injected into the patient. The tagged antibodies quickly and selectively bind to the diseased cells or microbes in the blood stream and affected organs. These cells or microbes are then selectively destroyed by irradiation of these complexes with light of the proper wavelength. This light activates the photosensitive material which then creates singlet oxygen that destroys the microbe or cell. Toxic products of lysis are quickly discharged from the body by activation of the reticuloendothelial system. IPT has been demonstrated by Biotronics to be very effective in the in vitro selective destruction of specified cell types. In a proposed AIDS-treatment research program, IPT will be first demonstrated in vitro for a set of infected blood samples using commercially-available antibodies labeled with appropriate photosensitizers. Efficacy will be determined by a p24 antigen immunodiagnostic test that will indicate the % inhibition in comparison to controls and samples treated with the drug AZT. Subcontracted animal efficacy studies will use a SCID-hu mouse model and PCR/DNA-RNA for endpoint analysis. Toxicity studies of animal (rat) models will be based on post-treatment investigations of lymph nodes, spleen, liver and other organs.

    Following the transfusion of a young woman with two units of blood infected by human immunodeficiency virus (HIV) during a Cesarean section performed at the Obstetrics and Gynecology Unit of Port-Royal Hospital in Paris in 1984, the author realized the danger that this virus would represent for women and their children, at a time when the infection seemed to be confined to homosexuals, drug addicts, hemophiliacs and transfusion recipients. He was confronted with a whole series of issues, including the rejection of HIV-positive women; the need for special precautions in the labor room and operating theater; and the need for these patients to be managed in a single center staffed by skilled and willing healthcare professionals who could help them decide whether or not to continue the pregnancy. The main risks at this time were the onset of life-threatening opportunistic infections during pregnancy and HIV transmission to the child (estimated at 20% to 30%). Other thorny issues included the case of couples wishing to have children when either of the two members was infected, and the question of professional confidentiality when an immunocompromised HIV-seropositive husband stubbornly refused to inform his wife or to use condoms. It seemed important to bring these women together, especially those of African origin, within a self-help group where they could express themselves openly and discuss their difficulties. Screening for HIV antibodies in early pregnancy became necessary to permit preventive treatment of mother-child HIV transmission, and to inform pediatricians. There was also a need to estimate and monitor the seroprevalence of HIV among pregnant women, and this was done by conducting a "sentinel" survey that was subsequently taken over by INSERM and the European Centre for the Epidemiological Monitoring of AIDS. After listing many other issues that were hotly debated over the years, the author describes how, at the beginning of the epidemic, new proposals

    Full Text Available The spread of human immunodeficiency virus (HIV infection and the resulting acquired immune deficiency syndrome (AIDS is a major health concern in many parts of the world, and mathematical models are commonly applied to understand the spread of the HIV epidemic. To understand the spread of HIV and AIDS cases and their parameters in a given population, it is necessary to develop a theoretical framework that takes into account realistic factors. The current study used this framework to assess the interaction between individuals who developed AIDS after HIV infection and individuals who did not develop AIDS after HIV infection (pre-AIDS. We first investigated how probabilistic parameters affect the model in terms of the HIV and AIDS population over a period of time. We observed that there is a critical threshold parameter, R0, which determines the behavior of the model. If R0 ≤ 1, there is a unique disease-free equilibrium; if R0 1, the disease-free equilibrium is unstable. We also show how a Markov chain Monte Carlo (MCMC approach could be used as a supplement to forecast the numbers of reported HIV and AIDS cases. An approach using a Monte Carlo analysis is illustrated to understand the impact of model-based predictions in light of uncertain parameters on the spread of HIV. Finally, to examine this framework and demonstrate how it works, a case study was performed of reported HIV and AIDS cases from an annual data set in Malaysia, and then we compared how these approaches complement each other. We conclude that HIV disease in Malaysia shows epidemic behavior, especially in the context of understanding and predicting emerging cases of HIV and AIDS.

    Having lost sight of its goal, the International Committee on Taxonomy of Viruses has redoubled its efforts. That goal is to arrive at a consensus regarding virus classification, i.e., proper placement of viruses in a hierarchical taxonomic scheme; not an easy task given the wide variety of recognized viruses. Rather than suggesting a continuation of the bureaucratic machinations of the past, this opinion piece is a call for insertion of common sense in sorting out the avalanche of information already, and soon-to-be, accrued data. In this way information about viruses ideally would be taxonomically correct as well as useful to working virologists and journal editors, rather than being lost, minimized, or ignored.

    The belief that acquired immunodeficiency syndrome (AIDS) is a form of genocide targeted at the black population is prevalent in black communities in the United States. Public health authorities are distrusted, in part because of the legacy of the Tuskegee Study of untreated syphilis, a perceived racist experiment. For effective interventions to prevent the transmission of human immunodeficiency virus in black communities, genocidal fears and beliefs must be addressed and black community leaders should be involved in planning and implementation.

With the identification of the human immunodeficiency virus (HIV) as the etiology of this syndrome, there has been exponential growth in our understanding of this devastating immune disorder. During the first decade of the acquired immunodeficiency syndrome (AIDS), there was an explosion of cases in the United States and Africa.
