Research paper thumbnail of Antiretroviral therapy enrollment characteristics and outcomes among HIV-infected adolescents and young adults compared with older adults--seven African countries, 2004-2013

MMWR. Morbidity and mortality weekly report, Jan 28, 2014

In 2012, an estimated 2,500 (40%) of all 6,300 daily new HIV infections occurred among persons aged 15-24 years. Difficulty enrolling adolescents and young adults in ART and high rates of loss to follow-up (LTFU) after ART initiation might be contributing to mortality and HIV incidence in this age group, but data are limited. To evaluate age-related ART retention challenges, data from retrospective cohort studies conducted in seven African countries among 16,421 patients, aged ≥15 years at enrollment, who initiated ART during 2004-2012 were analyzed. ART enrollment and outcome data were compared among three groups defined by ...

Few studies have examined HIV viral dynamics in this setting. Methods: We compared HIV-1 and HIV-2 viral loads from 65 dually infected, antiretroviral therapy-naïve Senegalese subjects. Participants provided demographic information and blood, oral fluid, and cervicovaginal lavage (CVL) or semen samples for virologic and immunologic testing. Associations between HIV-1 and HIV-2 levels in plasma, PBMC, oral and genital samples were assessed using linear regression models with generalized estimating equations to account for subjects with multiple samples over time. Results: In analyses adjusting for CD4 count, age, sex, and commercial sex work, HIV-1 RNA levels were significantly higher than HIV-2 levels in semen (b02.05 log 10 copies/ml, 95% CI 0.44 to 3.66), CVL (b 01.37, 95% CI 0.83 to 1.91), and oral fluids (b 01.93, 95% CI 1.56 to 2.30). HIV-1 and HIV-2 PBMC viral DNA loads were similar in those with normal immune function (CD4 counts above 500 cells/ml) (b 00.17 log 10 copies/mg of PBMC DNA, 95% CIÁ0.58 to 0.24), but compared to those with high CD4 counts, subjects with CD4 counts below 500 cells/ml had higher HIV-1 and lower HIV-2 levels. In plasma, subjects with CD4 counts above 500 cells/ml had mean HIV-1 plasma RNA viral loads 0.87 log 10 copies/ml higher (95% CI 0.35 to 1.38) than HIV-2, while among subjects with CD4 counts between 200 and 500 cells/ml or below 200 cells/ml, this difference increased to 4.28 and 4.35 log 10 copies/ml (95% CIs 2.51 to 6.04 and 2.67 to 6.04), respectively. Conclusion: Our data are consistent with the hypothesis that with decreasing CD4 counts and HIV disease progression, HIV-1 may outcompete HIV-2 in dually-infected individuals. This finding may help explain the differences in epidemiology between HIV-1 and HIV-2.

These data were collected in the context of the Demographic and Health Surveys programme (DHS) between 1986 and 1989. Bottle use appears to be very common in most countries. Only six of the 22 countries had levels of bottle use of less than 20 per cent, and all these countries are in sub-Saharan Africa. The policy implications are discussed briefly.

In this paper we assess the accuracy and completeness of mothers' recall of diarrhoea in 19 national DHS surveys and discuss the implications for health interview surveys in developing countries. It is concluded that there is under-reporting of diarrhoea if the recall period is longer than 2-3 days, whereas there may be over-reporting of very recent or current diarrhoea in most DHS surveys. Reporting errors appear to vary considerably between countries, which affects the comparability of survey results. A second and related issue, that is addressed in this paper, is the reporting of treatment practices by duration of diarrhoeal episode. There were no major differences in reported treatment patterns between children with diarrhoea that terminated in the last two weeks and children with current diarrhoea of at least two days' duration. The implications of the findings for retrospective surveys on childhood morbidity and treatment patterns are discussed.

The first part of the analysis presents direct estimates of orphan prevalence in 17 countries during the period 1995-2000. We find a strong correlation between orphanhood prevalence and national adult HIV prevalence estimates lending support to the interpretation of the orphan crisis as, in large part, AIDS-related. The second part of the analysis consists of an in-depth study of trends and age-patterns in orphan prevalence and welfare in the 1990s for five countries that have had widely divergent HIV prevalence levels (Zimbabwe, Kenya, Tanzania, Ghana, and Niger). The vulnerability of orphans with respect to their situation in households and educational opportunities is evaluated in relation to non-orphans' experience. The results of the analysis indicate that losing one or both parents is significantly associated with diminished chances of being at the appropriate grade level for age. Our results are interpreted in the context of societal responses to the crisis, and potential recommendations for intervention.

In a nationally representative household survey in Swaziland, 18,172 adults, age 18 to 49 years, received home-based HIV rapid testing in 2010 and 2011. Of the 18,172 individuals, 5,822 (32.0%) were Ab positive (Ab) by the Determine HIV-1/2 Ab/Ab combo test, and 5,789 (99.4%) of those were confirmed to be reactive in the Uni-Gold test. Determine combo identified 12 individuals as having acute infections (Ag/Ab negative [Ab]); however, none had detectable HIV-1 RNA and 8 of 12 remained HIV negative at their 6-week follow-up visit (4 were lost to follow-up). All RT-nonreactive samples were pooled and tested by nucleic acid amplification testing (NAAT) to iden-tify acute infections. NAAT identified 13 (0.1%) of the 12,338 HIV antibody-negative specimens as HIV RNA positive, w...

Sibling history data allowed for direct estimation of overall adult mortality by sex as well as maternal mortality in particular. Results showed that among surviving siblings current age (used to estimate death exposure) was not reported for less than 1% of siblings while among the deceased siblings complete reporting of age at death and years were recorded. The net effect of these opposing sex-specific age patterns was that the female and male mortality rates for ages 15-49 were equal (4.7 deaths/1000 years of exposure); though female mortality was higher than male mortality. Maternal deaths represented 27% of all deaths in women aged 15-49. Thus the maternal mortality ratio was estimated to be 590 maternal deaths per 100000 live births. However the sparseness of KDHS sibling history data makes it statistically reliable across the relevant calendar periods.

The aim was to determine whether data collection by proxy from mothers sisters could be used to estimate childhood mortality rates and to describe the demographic situation and use of maternity services in order to improve local programs. The sample was drawn from the Kwimba District of Mwanza Region and south of Lake Victoria. The area is largely subsistence-farmed with low modernization and educational levels. The Sukuma group is the dominant ethnic group. The study population resided mostly within the primary health care program service area which includes a large hospital for tertiary care needs. Phase I involved a representative sample of 1488 households and 2130 women aged 15-50 years. Data collection included full birth histories of own respondent and sibling histories. Phase II was conducted one month after Pha...
