Two-thirds of the world's HIV-infected people live in sub-Saharan Africa, and more than 1.5 million of them die annually. As access to antiretroviral treatment has expanded within the region; early pessimism concerning the delivery of antiretroviral treatment using a large-scale public health approach has, at least in the short term, proved to be broadly unfounded. Immunological and virological responses to ART are similar to responses in patients treated in high-income countries. Despite this, however, early mortality rates in sub-Saharan Africa are very high; between 8 and 26% of patients die in the first year of antiretroviral treatment, with most deaths occurring in the first few months. Patients typically access antiretroviral treatment with advanced symptomatic disease, and mortality is strongly associated with baseline CD4 cell count less than 50 cells/mul and WHO stage 4 disease (AIDS). Although data are limited, leading causes of death appear to be tuberculosis, acute sepsis, cryptococcal meningitis, malignancy and wasting syndrome. Mortality rates are likely to depend not only on the care delivered by antiretroviral treatment programmes, but more fundamentally on how advanced disease is at programme enrollment and the quality of preceding healthcare. In addition to improving delivery of antiretroviral treatment and providing it free of charge to the patient, strategies to reduce mortality must include earlier diagnosis of HIV infection, strengthening of longitudinal HIV care and timely initiation of antiretroviral treatment. Health systems delays in antiretroviral treatment initiation must be minimized, especially in patients who present with advanced immunodeficiency.

    • "Timely presentation at services and minimisation of delays in initiation of treatment have been identified as potentially important contributory factors to reducing the high levels of early mortality observed in treatment programmes for HIV/AIDS [1,2]. Recent research carried out among people living with HIV/AIDS has led to wider recognition of the important contribution of mental disorder, in particular, depression, to HIV clinical outcomes. "

    ABSTRACT: Background Successful linkage to care is increasingly recognised as a potentially important factor in determining the success of Antiretroviral Therapy treatment programmes. However, the role of psychological factors during the early part of the continuum of care has so far been under-investigated. The objective of the Umeed study was to evaluate the impact of Common Mental Disorder (CMD), hazardous alcohol use and low cognitive functioning upon attendance for post-test counselling and linkage to care among people attending for HIV-testing in Goa, India. Methods The study was a prospective cohort design. Participants were recruited at the time of attending for testing and were asked to complete a baseline interview covering sociodemographic characteristics and mental health exposures. HIV status, post-test counselling (PTC) and Antiretroviral Treatment (ART) Centre data were extracted from clinical records. Results Among 1934 participants, CMD predicted non-attendance for PTC (adjusted OR = 0.51, 0.21-0.82). There was tentative evidence of an association between hazardous alcohol use and non-attendance for PTC (adjusted OR = 0.69, 0.45-1.02). There was no evidence of an association between CMD caseness and attendance for ART. However, post-hoc analyses showed an association between increasing symptoms of CMD and non-attendance. Conclusions Although participation rates were high (86%), non-participation was a possible source of bias. Cognitive tests had not been previously validated in a young population in Goa. The context in which cognitive testing took place may have contributed to the high prevalence of low scores. Findings suggest the need to move towards a broader conceptualisation of the interrelationship between mental health and HIV. It may be important to consider the impact of symptoms of depression and anxiety at every stage of the continuum of care, including immediately after diagnosis and when initiating contact with treatment services.

    • "However the quality of pre-ART care that they received was poor – as they remained without a recent CD4 count. It is essential that pre-ART patients have regular CD4 counts and that ART is initiated as soon as indicated to decrease morbidity and mortality associated with low CD4 counts [3], [5], [21]. Other studies confirm poor retention in and quality of pre-ART care as patients still initiate ART at low baseline CD4 counts (below 200 cells/mm3) [5]. "

    ABSTRACT: Few studies have evaluated access to and retention in pre-ART care. To evaluate the proportion of People Living With HIV (PLWH) in pre-ART and ART care and factors associated with retention in pre-ART and ART care from a community cohort. A cross sectional survey was conducted from February - April 2011. Self reported HIV positive, negative or participants of unknown status completed a questionnaire on their HIV testing history, access to pre-ART and retention in pre-ART and ART care. 872 randomly selected adults who reported being HIV positive in the ZAMSTAR 2010 prevalence survey were included and revisited. 579 (66%) reconfirmed their positive status and were included in this analysis. 380 (66%) had initiated ART with 357 of these (94%) retained in ART care. 199 (34%) had never initiated ART of whom 186 (93%) accessed pre-ART care, and 86 (43%) were retained in pre-ART care. In a univariable analysis none of the factors analysed were significantly associated with retention in care in the pre-ART group. Due to the high retention in ART care, factors associated with retention in ART care, were not analysed further. Retention in ART care was high; however it was low in pre-ART care. The opportunity exists, if care is better integrated, to engage with clients in primary health care facilities to bring them back to, and retain them in, pre-ART care.

    • "The widespread use of HAART has caused a decline in mortality rates in PLHIV [1], although rates are still higher in developing countries than in developed countries [2]. Population surveys and autopsy studies have shown that many of these deaths are due to undiagnosed and therefore untreated tuberculosis (TB) [3-5]. TB is the leading cause of death related to HIV worldwide [3,6-9] contributing to an estimated 24% of deaths [1], and this alone may prevent meeting the WHO target of halving the 1990 levels of TB mortality [6].

    ABSTRACT: Tuberculosis (TB) is the leading cause of death related to HIV worldwide. This study analyzes the survival of People Living with HIV (PLHIV) reporting cough without bacteriological confirmation of TB and identify factors associated with death. Prospective cohort with a consecutive sample of PLHIV, aged >= 18 years. Patient inclusion criteria were complaint of current cough of any duration at the time of the first study interview or during their subsequent routine visits to health services and for whom AFB sputum smear was either negative or not performed during the whole follow-up period. Kaplan-Meier method was used to calculate the probability of survival. We estimated the Hazard Ratio (HR) in bivariate and multivariate Cox regression analyses. Mortality was 4.6 per 100 py; 73% were receiving HAART at recruitment. Average time from the first recorded date of cough until empirical treatment for tuberculosis was six months. Mortality was higher when the CD4 count was low (HR = 5.3; CI 95%: 3.2-9.0; p = 0.000), in those with anemia (HR = 3.0; CI 95%: 1.6-5.6; p = 0.001) and with abnormal chest X-rays (HR = 2.4; CI 95%: 1.4-4.0; p = 0.001). Mortality was higher in those receiving empirical TB treatment (HR = 2.4; CI 95%: 1.4-4.0; p = 0.002), but only in those with normal X-rays, no history of tuberculosis and no bacteriology requests. Empirical treatment for TB was more frequent in PLHIV with low CD4 counts, anemia, history of opportunistic infections, weight loss, previous tuberculosis, negative bacteriology test (as opposed to not having a test) and abnormal chest X-ray. Higher mortality in PLHIV reporting a current cough without bacteriological confirmation of tuberculosis was identified for those with a CD4 cell count <200, abnormal chest X-ray, anemia and empirical treatment for tuberculosis. Mortality was not significantly higher in those empirically treated for TB, who had three characteristics suggestive of the disease (abnormal chest X-ray, history of TB treatment, AFB sputum smear or M.tb culture testing). Routine cohorts are not an adequate setting to evaluate the impact of empirical treatment for TB on the mortality of PLHIV.
