Contact with HIV prevention programmes & willingness for new interventions among truckers in India.

Background & objectives: Systematic data on existing coverage and willingness for HIV prevention strategies among truckers are not readily available in India. The present study aimed to further the understanding on contact of truckers with existing HIV prevention services and to assess willingness for new HIV prevention strategies. Methods: A total of 1,800 truck drivers and helpers aged 16-65 yr passing through Hyderabad were approached to assess contact made with HIV prevention programmes, history of previous HIV testing and their acceptance for circumcision, oral HIV testing, new medications to control HIV (PrEP) and telephonic counselling. Dried blood samples were collected on filter paper and tested for HIV. Multiple logistic regression was performed for analysis of association between contact with HIV prevention programme and socio-demographic, sexual risk behaviour variables and work characteristics. Results: A total of 1,602 (89%) truckers gave interview and provided blood sample. Forty five truckers tested positive for HIV resulting in HIV prevalence of 2.8 per cent (95% CI 2.0-3.6%). Only 126 truckers (7.9%; 95% CI 6.5-9.2%) reported ever being contacted by staff providing HIV prevention interventions. Previous HIV testing was reported by19 per cent (95% CI 17.3-21.2%). Those reporting contact with HIV prevention programmes ever were more likely to have undergone HIV testing (odds ratio 3.6, 95% CI 2.4-5.4). The acceptance for pre-exposure prophylaxis (PrEP) was 87 per cent, oral HIV testing 98 per cent, and telephonic counselling 82 per cent, but was only 9 per cent for circumcision.Truckers who reported having sex with a man and those who halted regularly at dhabas were significantly more willing to undergo circumcision for HIV prevention (odds ratios 2.7, 95% CI 1.4-5.4 and 2.1, 95% CI 1.3-3.2, respectively). Interpretation & conclusions: Our findings showed that truckers had low contact with HIV prevention programmes, suggesting a need for urgent measures to reach this population more effectively. The willingness for new HIV interventions was high except for circumcision. These findings could be used for further planning of HIV prevention programmes for truckers in India

Men who have sex with men in India: A diverse population in need of medical attention.

A significant proportion of men engage in sexual relationships with other men which has direct health implications, but the unique health care needs of these patients are often ignored or overlooked. Moreover, due to a fear of stigmatization by the medical community, one of the more significant health risks for men who have sex with men (MSM) may be that they avoid routine or appropriate health care. Physicians and other providers can help overcome this barrier and improve the health care of MSM by keeping a non-judgmental attitude toward these patients, differentiating sexual behaviour from sexual identity, communicating with gender neutral terms, and maintaining awareness of how their own attitudes affect clinical judgment. The purpose of this article is to help contextualize health issues affecting MSM and provide a framework for physicians and other providers to deliver optimum and appropriate health care for men who have sex with men in India.

HIV in Indian MSM: Reasons for a concentrated epidemic & strategies for prevention.

Men who have sex with men (MSM) in India are disproportionately likely to be HIV-infected, and face distinct psychosocial challenges. Understanding the unique socio-cultural issues of MSM in India and how they relate to HIV risk could maximize the utility of future prevention efforts. This review discusses: (i) the importance of addressing co-occurring mental health issues, such as depression, which may interfere with MSM’s ability to benefit from traditional risk reduction counselling, (ii) reducing HIV-related stigma among health providers, policymakers and the lay public, and (iii) the role for nongovernmental organizations that work with the community to play in providing culturally relevant HIV prevention programmes for MSM.

Low-cost assays for monitoring HIV infected individuals in resource-limited settings.

Use of a combination of CD4 counts and HIV viral load testing in the management of antiretroviral therapy (ART) provides higher prognostic estimation of the risk of disease progression than does the use of either test alone. The standard methods to monitor HIV infection are flow cytometry based for CD4+ T cell count and molecular assays to quantify plasma viral load of HIV. Commercial assays have been routinely used in developed countries to monitor ART. However, these assays require expensive equipment and reagents, well trained operators, and established laboratory infrastructure. These requirements restrict their use in resource-limited settings where people are most afflicted with the HIV-1 epidemic. With the advent of low-cost and/or low-tech alternatives, the possibility of implementing CD4 count and viral load testing in the management of ART in resource-limited settings is increasing. However, an appropriate validation should have been done before putting them to use for patient testing.

HIV-1 western blot assay: What determines an indeterminate status?

BACKGROUND: The Western blot assay is the gold standard for the detection of antibodies to human immunodeficiency virus type 1 (HIV-1). However, indeterminate Western blot reactivity to HIV-1 proteins may occur in individuals, who may not be infected with HIV. AIM: This retrospective study was aimed to determine the diagnostic value of the interpretation criteria in relation to commercial kits for HIV-1 diagnosis. METHODS AND MATERIALS: A total of 556 serum/plasma specimens collected from high-risk population attending our HIV clinic from 2000-2004 were tested by three different western blot kits: NEW LAV BLOT I (n=244), HIV BLOT 2.2; (n=112), Genetic Systems HIV-1 (n=237). And the results of western blot strips were analyzed using the various interpretation criteria: WHO/NACO, CDC/ ASTPHLD, ARC, FDA, CRSS and JHU. Some specimens were run on more than one kit. RT-PCR assay was performed on 5 specimens, which were indeterminate with LAV BLOT I. RESULTS: The discrepancy in LAV BLOT I positive results were between 157(64)-176(72), and indeterminate results were between 44(18) to 63(25). No such variations were observed in genetic systems. There are some HIV negative (by PCR) specimens were indeterminate in LAV BLOT I revealing the kit more sensitive and less effective for diagnostic purpose. CONCLUSION: The genetic systems kit is superior to other kits we analyzed and its results are concordant with HIV-1 PCR results. To report, the choice of western blot commercial kit is paramount important than the use of particular interpretation criteria for the diagnosis of HIV-1.

An approach to addressing ethical issues in a community-based risk assessment for HIV: a case from Chennai, India.

Community-based assessment of HIV prevalence and behavioural risk factors is the basis for deciding priorities of prevention and care programmes. Here, upholding the human rights of participants in assessment is of utmost importance. The objective of the paper was to describe the process of implementation of an epidemiological survey to assess HIV-related behavioural and biological factors in Chennai city in South India and to suggest an ethical framework for conducting similar assessment activities in developing-country settings. A survey was conducted with participation from residents (n=1,659) of low-income urban communities (slums) as part of a community-based HIV/STD-prevention trial. Administration of the survey was preceded by extensive community contact and household visits to inform community members about the trial and assessment activities. Formative research further strengthened rapport with community, highlighted community concerns, and identified HIV-related risk behaviours that informed questionnaire design. The process of obtaining informed consent began before assessment activities and provided an opportunity for individuals to discuss participation with their families and friends. Privacy during assessment, comprehensive follow-up care for those who tested positive for HIV/STDs, such as nutritional and prevention counselling, referral services for opportunistic infections, and antenatal-care options for pregnant women increased trust and credibility of the project. The sustained availability of trial staff to facilitate access to resources to address non-HIV/STD-related felt-needs further strengthened participation of the community members. These resources included liaison services with local government to obtain public services, such as water and electricity and resources, to address concerns, such as alcohol abuse and domestic violence. Based on this experience, an ethical framework is suggested for conducting HIV epidemiological risk assessment in developing countries. This framework discusses the role of community participation, transparent and comprehensive informed consent, timely dissemination of results, and access to follow-up care for those living with HIV/STDs.

Clinical profile of HIV in India.

The clinical course of human immunodeficiency virus (HIV) disease and pattern of opportunistic infections varies from patient to patient and from country to country. The clinical profile of HIV disease in India includes a wide range of conditions like tuberculosis, cryptococcal meningitis, popular pruritic eruptions, and cytomegalovirus retinitis, among others. Tuberculosis is the most common opportunistic infection in Indian patients with HIV. Occurrence of various AIDS-associated illnesses determines disease progression. Mean survival time of Indian patients after diagnosis of HIV is 92 months. In this review, we discuss the clinical profile of HIV disease through an organ system-based approach. With the availability of antiretroviral therapy at lower cost, the clinical profile of HIV disease in India is now changing to include drug-related toxicities and immune reconstitution syndrome.

Low-cost monitoring of HIV infected individuals on highly active antiretroviral therapy (HAART) in developing countries.

The standard methods to monitor HIV infection are flow cytometry-based for CD4+ T lymphocyte count and molecular assays to quantify plasma viral load of HIV. Few laboratories in resource-limited countries can run these tests as a majority of the HIV infected individuals are poor. A number of currently available low-cost assays which require less expensive equipment and reagents, may be well-suited to such countries. These include manual and ELISA based CD4 cell assays, and ultrasensitive reverse transcriptase quantitation (Cavidi) and p24 (ELAST) assays to monitor virus load. But better internal quality assurance and quality control (QA/QC) programmes are essential. This review discusses the low-cost assays and their role in clinical monitoring of HIV infected individuals in resource-limited countries like as India.
