Bottlenecks and opportunities for delivering integrated pediatric HIV services in Nepal

Stigma, discrimination and HIV or AIDS: an empirical investigation of Asian immigrants and refugees in Canada

Purpose

HIV or AIDS remains invisible and dismissed by most South Asians living in Canada as HIV or AIDS issues are perceived as an offshoot of Western lifestyle linked with drug use and promiscuity. This paper aims to look into how people living with HIV or AIDS (PLWHA) cope with prejudice and stigma.

Design/methodology/approach

To guide this research, a constructivist grounded theory approach was adopted as the theoretical and methodological framework. The authors reached the participants through a Toronto-based group that works with PLWHA. The authors chose their respondents in a snowball method and interviewed them both in person and online.

Findings

This paper identifies how South Asian immigrants and refugees/refugees with HIV or AIDS claimants are vulnerable to discrimination in Canada due to the following factors, which include but are not limited to: a lack of information about HIV and AIDS incidence in the community; and the Canadian health system's inability to respond appropriately to the lack of information.

Practical implications

HIV service engagements should take place within the context of a constellation of local traditions, or standardized expectations of patient engagement with HIV services can be counterproductive.

Originality/value

It is critical that governmental action prioritizes increasing public understanding of stigma. To minimize the consequences of HIV-related discrimination and stigma, misconceptions about HIV transmission must be debunked.

Integrated TB and HIV care for Mozambican children: temporal trends, site-level determinants of performance, and recommendations for improved TB preventive treatment

BACKGROUND

Pediatric tuberculosis (TB), human immunodeficiency virus (HIV), and TB-HIV co-infection are health problems with evidence-based diagnostic and treatment algorithms that can reduce morbidity and mortality. Implementation and operational barriers affect adherence to guidelines in many resource-constrained settings, negatively affecting patient outcomes. This study aimed to assess performance in the pediatric HIV and TB care cascades in Mozambique.

METHODS

A retrospective analysis of routine PEPFAR site-level HIV and TB data from 2012 to 2016 was performed. Patients 0-14 years of age were included. Descriptive statistics were used to report trends in TB and HIV indicators. Linear regression was done to assess associations of site-level variables with performance in the pediatric TB and HIV care cascades using 2016 data.

RESULTS

Routine HIV testing and cotrimoxazole initiation for co-infected children in the TB program were nearly optimal at 99% and 96% in 2016, respectively. Antiretroviral therapy (ART) initiation was lower at 87%, but steadily improved from 2012 to 2016. From the HIV program, TB screening at the last consultation rose steadily over the study period, reaching 82% in 2016. The percentage of newly enrolled children who received either TB treatment or isoniazid preventive treatment (IPT) also steadily improved in all provinces, but in 2016 was only at 42% nationally. Larger volume sites were significantly more likely to complete the pediatric HIV and TB care cascades in 2016 (p value range 0.05 to < 0.001).

CONCLUSIONS

Mozambique has made significant strides in improving the pediatric care cascades for children with TB and HIV, but there were missed opportunities for TB diagnosis and prevention, with IPT utilization being particularly problematic. Strengthened TB/HIV programming that continues to focus on pediatric ART scale-up while improving delivery of TB preventive therapy, either with IPT or newer rifapentine-based regimens for age-eligible children, is needed.

A study using knowledge, attitude and practices on the prevention of HIV-1 vertical transmission with outcomes in early infant HIV-1 diagnosis in Eastern Uganda

OBJECTIVE

The objective of this study was to assess trends over time using knowledge, attitude and practices (KAP) among mothers living with HIV and rates of early infant diagnosis (EID) of human immunodeficiency virus type 1 (HIV-1) in a hospital in Eastern Uganda, which is included in the National HIV Prevention Strategy (NHPS) in Uganda.

METHODS

A thematic qualitative assessment was conducted using focus group discussions (FGDs) with pregnant women, breastfeeding mothers and women attending the antiretroviral therapy (ART) clinic, all living with HIV. In addition, we have performed key informant interviews (KIIs) in October 2011 (baseline) and November 2016 (follow-up) at Mbale Regional Referral Hospital. Data were captured through customised source documents, written narratives and voice recordings. Social scientists decoded, analysed and interpreted the qualitative data with quality control. Retrospective data were obtained from EID registers for 2010 before and 2015 at the end of the NHPS, respectively. Supplementary quantitative data from the same hospital regarding trends of HIV-1 vertical transmission rates were collected from EID registers at baseline and at follow-up. Comparisons were made between HIV-1 transmission rates and KAP levels at baseline and at follow-up.

RESULTS

Three paired sets of FGD sessions, consisting of 8-10 participants for each of the groups of pregnant women, breastfeeding mothers and women attending ART clinic, all living with HIV, were conducted at baseline and at follow-up. Age ranged from 17 to 40 years. Two sets of paired KII interviews corresponding to the periods before and after the NHPS were also held. All study FGDs and KIIs showed improvement in KAP on HIV-1 vertical transmission and lower EID rates when comparing baseline to the follow-up period [9/69 (13.0%) and 14/336 (4.2%)], respectively (P = 0.004).

CONCLUSION

Improvement was noted in KAP on HIV-1 vertical transmission in pregnant women, breastfeeding mothers and women attending ART clinic, all HIV positive, in a regional referral hospital in Eastern Uganda over a 5-year period and was associated with a reduction in vertical transmission rates. Our data suggest that KAP is an effective type of intervention with regard to the prevention of HIV-1 vertical transmission in this population in resource-limited settings.

Immunologic-based Diagnosis of Latent Tuberculosis Among Children Younger Than 5 Years of Age Exposed and Unexposed to Tuberculosis in Tanzania

BACKGROUND

Childhood tuberculosis (TB) is acquired after exposure to an infectious TB case, often within the household. We prospectively screened children 6-59 months of age, exposed and unexposed to an infectious TB case within the same household, for latent tuberculosis infection (LTBI), in Dar es Salaam, Tanzania.

METHODS

We collected medical data and clinical specimens (to evaluate for helminths, TB and HIV coinfections) and performed physical examinations at enrollment and at 3-month and 6-month follow-up surveys. LTBI was assessed using QuantiFERON-TB Gold (QFT) at enrollment and at 3 months.

RESULTS

In total, 301 children had complete data records (186 with TB exposure and 115 without known TB exposure). The median age of children was 26 months (range: 6-58); 52% were females, and 4 were HIV positive. Eight children (3%) developed TB during the 6-month follow-up. We found equal proportions of children with LTBI among those with and without exposure: 20% (38/186) versus 20% (23/115) QFT-positive, and 2% (4/186) versus 4% (5/115) indeterminate QFT. QFT conversion rate was 7% (22 children) and reversion 8% (25 children). Of the TB-exposed children, 72% initiated isoniazid preventive therapy, but 61% of parents/caregivers of children with unknown TB exposure and positive QFT refused isoniazid preventive therapy.

CONCLUSIONS

In this high burden TB setting, TB exposure from sources other than the household was equally important as household exposure. Nearly one third of eligible children did not receive isoniazid preventive therapy. Evaluation for LTBI in children remains an important strategy for controlling TB but should not be limited to children with documented TB exposure.

HIV/AIDS in the South-East Asia region: progress and challenges

The South-East Asia region, with 11 member states, has an estimated 3.5 million people living with HIV (PLHIV). More than 99% of PLHIV live in five countries where HIV prevalence among the population aged 15-49 remains low but is between 2% and 29% among key populations. Since 2010, the region has made progress to combat the epidemic. Mature condom programmes exist in most countries but opioid substitution therapy, and needle and syringe exchange programmes need to be scaled up. HIV testing is recommended nationwide in four countries and is prioritised in high prevalence areas or for key populations in the rest. In 2015, PLHIV aware of their HIV status ranged from 26% to 89%. Antiretroviral therapy (ART) is recommended for all PLHIV in Thailand and Maldives while six countries recommend ART at CD4 cell counts <500 cells/mm3. In 2015, 1.4 million (39%) PLHIV were receiving ART compared to 670,000 (20%) in 2010. Coverage of HIV testing and treatment among HIV-positive pregnant women has also improved but remains low in all countries except Thailand, which has eliminated mother-to-child transmission of HIV and syphilis. Between 2010 and 2015, AIDS-related deaths and new HIV infections have shown a declining trend in all the high-burden countries except Indonesia. But the region is far from achieving the 90-90-90 target by 2020 and the end of AIDS by 2030. The future HIV response requires that governments work in close collaboration with communities, address stigma and discrimination, and efficiently invest domestic resources in evidence-based HIV testing and treatment interventions for populations in locations that need them most.

Obstetrical, maternal characteristics and outcome of HIV-infected rapid progressor infants at Yaounde: a retrospective study

BACKGROUND

Rapid progressors are exposed to HIV infection at an early stage of life, and the prognosis is poor without treatment. Reducing the proportion of infants who are rapid progressors, require strengthening strategies to achieve the highest level of performance for the PMTCT program.

METHODS

This was a retrospective study carried out on HIV infected infants aged less than 12 months, clinically classified stage 4 (WHO) or having CD4 count <25%. We described maternal and obstetrical characteristics of HIV-infected rapid progressors using univariate and bivariate analysis. Patients' survival was monitored from the inclusion time to the end of the study. We then estimated their probability of survival with or without anti-retroviral (ARV) treatment from birth using the Kaplan-Meier method.

RESULTS

The characteristics of the mothers of the 150 rapid progressors infants we included were: low level of education (OR=3.87; P=0.016), CD4 count less than 200/mm(3) (OR=43.3; P=0.000), absence of ARV prophylaxis (OR=6.02; P=0.043), or treatment with HAART (OR=5.74; P=0.000) during pregnancy. In the children, the most important findings were lack of co-trimoxazole prophylaxis (OR=11.61; P=0.000) and antiretroviral prophylaxis (OR=2.70; P=0.0344). The survival rate was 84.3% in infants who were receiving HAART as opposed to 43.3% in those who were not (P<0.05).

CONCLUSIONS

HIV infected women who are eligible should start antiretroviral treatment prior to a pregnancy, in order to improve their immunological status. This measure associated to cotrimoxazole prophylaxis and ART could improve their survival.
