Seroprevalence of SARS-CoV-2 antibodies and retrospective mortality in two African settings: Lubumbashi, Democratic Republic of the Congo and Abidjan, Côte d'Ivoire.

Although seroprevalence studies have demonstrated the wide circulation of SARS-COV-2 in African countries, the impact on population health in these settings is still poorly understood. Using representative samples of the general population, we evaluated retrospective mortality and seroprevalence of anti-SARS-CoV-2 antibodies in Lubumbashi and Abidjan. The studies included retrospective mortality surveys and nested anti-SARS-CoV-2 antibody prevalence surveys. In Lubumbashi the study took place during April-May 2021 and in Abidjan the survey was implemented in two phases: July-August 2021 and October-November 2021. Crude mortality rates were stratified between pre-pandemic and pandemic periods and further investigated by age group and COVID waves. Anti-SARS-CoV-2 seroprevalence was quantified by rapid diagnostic testing (RDT) and laboratory-based testing (ELISA in Lubumbashi and ECLIA in Abidjan). In Lubumbashi, the crude mortality rate (CMR) increased from 0.08 deaths per 10 000 persons per day (pre-pandemic) to 0.20 deaths per 10 000 persons per day (pandemic period). Increases were particularly pronounced among <5 years old. In Abidjan, no overall increase was observed during the pandemic period (pre-pandemic: 0.05 deaths per 10 000 persons per day; pandemic: 0.07 deaths per 10 000 persons per day). However, an increase was observed during the third wave (0.11 deaths per 10 000 persons per day). The estimated seroprevalence in Lubumbashi was 15.7% (RDT) and 43.2% (laboratory-based). In Abidjan, the estimated seroprevalence was 17.4% (RDT) and 72.9% (laboratory-based) during the first phase of the survey and 38.8% (RDT) and 82.2% (laboratory-based) during the second phase of the survey. Although circulation of SARS-CoV-2 seems to have been extensive in both settings, the public health impact varied. The increases, particularly among the youngest age group, suggest indirect impacts of COVID and the pandemic on population health. The seroprevalence results confirmed substantial underdetection of cases through the national surveillance systems.

High severity of abortion complications in fragile and conflict-affected settings: a cross-sectional study in two referral hospitals in sub-Saharan Africa (AMoCo study).

BACKGROUND: Abortion-related complications are one of the five main causes of maternal mortality. However, research about abortion is very limited in fragile and conflict-affected settings. Our study aims to describe the magnitude and severity of abortion-related complications in two referral hospitals supported by Médecins Sans Frontières and located in such settings in northern Nigeria and Central African Republic (CAR). METHODS: We used a methodology similar to the World Health Organization (WHO) near-miss approach adapted in the WHO multi-country study on abortion (WHO-MCS-A). We conducted a cross-sectional study in the two hospitals providing comprehensive emergency obstetric care. We used prospective medical records' reviews of women presenting with abortion-related complications between November 2019 and July 2021. We used descriptive analysis and categorized complications into four mutually exclusive categories of increasing severity. RESULTS: We analyzed data from 520 and 548 women respectively in Nigerian and CAR hospitals. Abortion complications represented 4.2% (Nigerian hospital) and 19.9% (CAR hospital) of all pregnancy-related admissions. The severity of abortion complications was high: 103 (19.8%) and 34 (6.2%) women were classified as having severe maternal outcomes (near-miss cases and deaths), 245 (47.1%) and 244 (44.5%) potentially life-threatening, 39 (7.5%) and 93 (17.0%) moderate, and 133 (25.6%) and 177 (32.3%) mild complications, respectively in Nigerian and CAR hospitals. Severe bleeding/hemorrhage was the main type of complication in both settings (71.9% in the Nigerian hospital, 57.8% in the CAR hospital), followed by infection (18.7% in the Nigerian hospital, 27.0% in the CAR hospital). Among the 146 women (Nigerian hospital) and 231 women (CAR hospital) who did not report severe bleeding or hemorrhage before or during admission, anemia was more frequent in the Nigerian hospital (66.7%) compared to the CAR hospital (37.6%). CONCLUSION: Our data suggests high severity of abortion-related complications in these two referral facilities of fragile and conflict-affected settings. Factors that could contribute to this high severity in these contexts include greater delays in accessing post-abortion care, decreased access to contraceptive and safe abortion care that result in increased unsafe abortions; as well as increased food insecurity leading to iron-deficiencies and chronic anaemia. The results highlight the need for better access to safe abortion care, contraception, and high quality postabortion care to prevent and manage complications of abortion in fragile and conflict-affected settings.

Burden of and risk factors for sexual violence among women with and without disabilities in two sub-Saharan African countries.

BACKGROUND: Available data suggest that women with disabilities have an increased risk of sexual violence, but little is known about the situation of those women living in resource-limited settings. OBJECTIVES: To assess the burden and examine the drivers of sexual violence among women with disabilities. METHODS: This is a pooled analysis of two population-based surveys conducted in Cameroon and Burundi. Adults with and without disabilities were randomly recruited from the general population. Structured interviews were conducted at both sites to collect data on participants' functional limitations, life-course history of sexual violence, education, employment, and resources. Only women with disabilities whose impairments started before the age of 10 years (n = 359) and women without disabilities (n = 720) are included in this analysis. The age-adjusted prevalence of violence was computed, and risk factors were assessed using a discrete survival regression and mediation analysis. RESULTS: At both sites, the participants with disabilities had a lower education level and had an increased risk of food insecurity. The pooled age-adjusted prevalence of lifetime sexual violence was 19.8% (95%CI:15.3-24.3) among women with disabilities and 11.7% (95%CI:9.3-14.1) among those without disabilities (ORap: 2.0, 95%CI:1.4-2.8). Women with cognitive limitations and those with visual impairments had the highest risk of sexual violence (ORap: 3.5 (95%CI:2.0-6.3) and 2.7 (95%CI:1.4-5.0), respectively). Over the life course, the risk of sexual violence was especially high among women with disabilities who had lived with an intimate partner before the age of 25 years (p < 0.001). Education level mediated approximately one-third of the total association between disability and sexual violence (p = 0.001). There was no evidence of an indirect effect through food insecurity. CONCLUSION: This study provides evidence of the high burden of sexual violence among women with disabilities who live in urban African contexts. The social environment and access to education may be key contributors to this vulnerability.

The multidimensional vulnerability of people with disability to HIV infection: Results from the handiSSR study in Bujumbura, Burundi.

BACKGROUND: In resource-limited contexts, available data indicate that people with disability are disproportionally affected by the HIV epidemic. While disability resulting from chronic HIV infection has received some attention, few epidemiologic studies have examined the vulnerability of people with disability to HIV acquisition. The aims of the study were as follows: to estimate and compare HIV prevalence among people with and without disability living in Bujumbura, Burundi; to examine how the interaction among disability, gender and socioeconomic environment shapes vulnerability to HIV; and to identify potential pathways to higher HIV risk. METHODS: In this cross-sectional population-based study, 623 persons with disability (302 with disability onset ≤10 years ["early disability"]) and 609 persons without disability matched for age, sex and location were randomly selected to be tested for HIV and to participate in an interview about their life history, their social environment and their knowledge of sexual health. FINDINGS: A total of 68% of men and 75% of women with disability were affected by multidimensional poverty compared to 54% and 46% of their peers without disability (p<0.0001). Higher HIV prevalence was observed among women with disability (12.1% [8.2-16]) than among those without (3.8% [1.7-6], ORa 3.8, p<0.0001), while it was similar among men with disability and those without (p = 0·8). Women with disability were also at higher risk of sexual violence than were those without (ORa 2.7, p<0.0001). The vulnerability of women with early disability to HIV was higher among those who were socially isolated (HIV prevalence in this group: 19% [12-27]). In addition, education level and sexual violence mediated 53% of the association between early disability and HIV (p = 0.001). INTERPRETATION: This study highlights how the intersection of disability, gender and social environment shapes vulnerability to HIV. It also shows that the vulnerability to HIV of women who grew up with a disability is mediated by sexual violence. FUNDING: This research was funded by the Netherlands Organization for Scientific Research (Grant W08.560.005) and the Initiative HIV-TB-Malaria (new name of the organisation).

"We give them threatening advice ": expectations of adherence to antiretroviral therapy and their consequences among adolescents living with HIV in rural Malawi.

INTRODUCTION: Many adolescents living with HIV in sub-Saharan Africa struggle to achieve optimal adherence to antiretroviral therapy (ART), but few studies have investigated how their treatment-taking decisions are influenced by their social interactions with providers, caregivers and community leaders. This study aims to explore the narratives that define expectations of adherence to ART among adolescents living with HIV in a rural Malawian setting. METHODS: Overall, 45 in-depth interviews were conducted in 2016 with adolescents living with HIV, caregivers, health workers and community leaders, and four group sessions using participatory tools were undertaken with adolescents. Interviews and group sessions were audio-recorded, transcribed and translated into English. Data were coded inductively and analysed thematically. RESULTS: Adolescents were given strict behavioural codes around optimal treatment adherence, which were often enforced through encouragement, persuasian and threats. In HIV clinics, some staff supported adolescents with broader concerns relating to living with HIV, but other measures to address sub-optimal adherence in HIV clinics were perceived by patients as punitive, including pill-counts and increased frequency of clinic visits. Community leaders felt responsible for young peoples' health, sometimes attempting to influence their treatment-taking by threatening to withdraw services, or to publically "out" those deemed to be non-adherent. At home, discussions with adolescents about HIV were often limited to dose reminders, and some caretakers resorted to physical punishment to ensure adherence. While some adolescents complied with strictly-enforced adherence rules, others demonstrated resistance by hiding missed doses, secretly throwing away drugs, or openly refusing to take them. CONCLUSIONS: The potential of young people to adhere to their ART may be undermined by restrictive messages and punitive approaches to enforce and control their engagement with treatment at home, in the clinic and in the wider community. Interventions should focus on creating safe spaces for adolescents to speak frankly about the adherence challenges that they face and support for caregivers including home-based interventions.

Disability and Access to Sexual and Reproductive Health Services in Cameroon: A Mediation Analysis of the Role of Socioeconomic Factors.

There is growing evidence showing that people with disabilities face more frequently socioeconomic inequities than their non-disabled peers. This study aims to examine to what extent socioeconomic consequences of disability contribute to poorer access to sexual and reproductive health (SRH) services for Cameroonian with disabilities and how these outcomes vary with disabilities characteristics and gender. It uses data from a population-based survey conducted in 2015 in Yaounde, Cameroon. Mediation analysis was performed to determine how much of the total association between disability and the use, satisfaction and difficulties to access SRH services was mediated by education level, material wellbeing lifetime work participation and availability of social support. Overall, disability was associated with deprivation for all socioeconomic factors assessed though significant variation with the nature and severity of the functional limitations was observed. Lower education level and restricted lifetime work mediated a large part of the association between disability and lower use of HIV testing and of family planning. By contrast, while people with disabilities reported more difficulties to use a SRH service, no mediating was identified. In conclusion, Cameroonians with disabilities since childhood have restricted access to SRH services resulting from socioeconomic factors occurring early during the life-course.

Retention in care among clinically stable antiretroviral therapy patients following a six-monthly clinical consultation schedule: findings from a cohort study in rural Malawi.

INTRODUCTION: Longer intervals between clinic consultations for clinically stable antiretroviral therapy (ART) patients may improve retention in care and reduce facility workload. We assessed long-term retention among clinically stable ART patients attending six-monthly clinical consultations (SMCC) with three-monthly fast-track drug refills, and estimated the number of consultations "saved" by this model of ART delivery in rural Malawi. METHODS: Stable patients (aged ≥18 years, on first-line ART ≥12 months, CD4 count ≥300 cells/mL3 , without opportunistic infections, not pregnant/breastfeeding) were eligible for SMCC, with three-monthly drug refills from community health workers. Early enrollees were those starting SMCC within six months of eligibility, while late enrollees started at least 6 months after first eligibility. Kaplan-Meier methods were used to calculate cumulative probabilities of retention, stratified by timing of their enrolment and from first six-monthly clinical consultation. Cox regression was used to measure attrition hazards from the first six-monthly clinical consultation and risk factors for attrition, accounting for the time-varying nature of their eligibility and enrolment in this model of care. RESULTS: From 2008 to 2015, 22,633 clinically stable patients from 11 facilities were eligible for SMCC for at least three months, contributing 74,264 person-years of observation, and 18,363 persons (81%) initiated this model of care. The median time from eligibility to enrolment was 12 months and the median cumulative time on SMCC was 14.5 months. Five years after first SMCC eligibility, cumulative probabilities of retention were 85.5% (95% CI: 84.0% to 86.9%) among early enrollees and 93% (95% CI: 92.8% to 94.0%) among late enrollees. The cumulative probability of retention from first SMCC was 97.0% (95% CI: 96.7% to 97.3%) and 86% (95% CI: 85% to 87%) at one and five years respectively. Among eligible patients initiating SMCC, the adjusted hazards of attrition were 2.4 (95% CI: 2.0 to 2.8) times higher during periods of SMCC discontinuation compared to periods on SMCC. Male sex, younger age, more recent SMCC eligibility and WHO Stage 3/4 conditions in the past year were also independently associated with attrition from SMCC. Approximately 26,000 consultations were "saved" during 2014. CONCLUSION: After five years, retention among patients attending SMCC was high, especially among women and older patients, and its scale-up could facilitate universal access to ART.

Neurodevelopmental outcomes in HIV-infected and uninfected African children.

OBJECTIVE: HIV infection is associated with cognitive impairments, but outcomes are poorly explored in children starting antiretroviral therapy (ART) early or in those exposed but uninfected. DESIGN: Nested cross-sectional evaluation of the neurocognitive and behavioural outcomes of HIV-infected, HIV-exposed uninfected (HEU) and HIV-unexposed (HUU) Cameroonian children at age 4-9 years prospectively followed. METHODS: Cognitive development was assessed in 127 HIV-infected, 101 HEU, 110 HUU children using the KABC-II, neurologic dysfunction using the Touwen examination and behavioural difficulties using the Strength and Difficulties Questionnaire (SDQ). Analyses were adjusted for children age, sex and primary language. Contextual factors were included in a second step to assess their effects on outcomes. RESULTS: All HIV-infected children were treated before 12 months. There was a negative linear gradient in KABC-II scores from HUU children to HEU and HIV-infected children [gradient: -6.0 (-7.7; -4.3) for nonverbal index, NVI, and -8.8 (-10.7; -6.8) for mental processing index, MPI]. After adjusting for contextual factors, scores of HEU children were not significantly different from those of HUU children (all P > 0.1) and differences between HIV-uninfected and HUU children reduced [NVI: from -11.9 (-15.3; -8.5) to -3.4 (-6.8; -0.01), MPI: from -17.6 (-21.3; -13.8) to -5.5 (-9.3; -1.7)]. Compared with uninfected children, HIV-infected children had more neurological dysfunctions and higher SDQ scores (P = 0.002). CONCLUSION: Despite early ART, perinatal-HIV infection is associated with poorer neurocognitive scores and increased behavioural difficulties during childhood. Contextual factors play an important role in this association, which emphasizes the need for early nutritional and developmental interventions targeting both HIV-affected infants and their relatives.

Long-term Mortality and Disability in Cryptococcal Meningitis: A Systematic Literature Review.

Cryptococcal meningitis (CM) is the primary cause of meningitis in adults with human immunodeficiency virus (HIV) infection and an emerging disease in HIV-seronegative individuals. No literature review has studied the long-term outcome of CM. We performed a systematic review on the long-term (≥3-month) impact of CM (Cryptococcus neoformans and Cryptococcus gattii) on mortality and disability in HIV-infected and non-HIV-infected adults. Although the quality of current evidence is limited, the long-term impact of CM on survival and disability seems to be high. One-year mortality ranged from 13% in an Australian non-HIV-infected C. gattii-infected cohort to 78% in a Malawian HIV-infected cohort treated with fluconazole monotherapy. One-year impairment proportions among survivors ranged from 19% in an Australian C. gattii cohort to >70% in a Taiwanese non-HIV- and HIV-infected cohorts. Ongoing early therapeutic interventions, early detection of impairments and access to rehabilitation services may significantly improve patients' survival and quality of life.

Prevalence of HIV infection among people with disabilities: a population-based observational study in Yaoundé, Cameroon (HandiVIH).

BACKGROUND: In resource-limited settings, people with disabilities have been left behind in the response to HIV. In the HandiVIH study, we estimate and compare HIV prevalence and associated risk factors between people with and without disabilities. METHODS: In this cross-sectional, population-based, observational study, we used two-phase random sampling to recruit adults with disabilities and a control group matched for age, sex, and residential location from households of the general population. We used the Washington Group Short Set of Questions on Disability to identify people with disabilities. We administered an HIV test and a life-course history interview to participants. The primary outcome was the prevalence of HIV among participants with and without disabilities. FINDINGS: Between Oct 2, 2014, and Nov 30, 2015, we recruited 807 people with disabilities and 807 participants without disabilities from Yaoundé, Cameroon. 28 of 716 people in the control population had a positive HIV test result (crude prevalence 3·9%, 95% CI 2·9-5·3) compared with 50 of 739 people with disabilities (6·8%, 5·0-8·6; conditional odds ratio [OR] 1·7; p=0·04). Women with disabilities were more often involved in paid sexual relationships than were women without disabilities (2·5% vs 0·5%, p=0·05). People with disabilities were also at increased risk of sexual violence than were women without disabilities (11·0% vs 7·5%, OR 1·5; p=0·01). Sexual violence and sex work were strongly associated with increased risk of HIV infection among participants with disabilities but not among controls (OR 3·0, 95% CI 1·6-5·6 for sexual violence and 12·3, 4·4-34·6 for sex work). Analyses were done in men and women. INTERPRETATION: The higher prevalence of HIV infection in people with disabilities than people without disabilities reflects a higher exposure to HIV infection as well as the presence of disability-associated HIV infection. The susceptibility of people with disabilities to HIV infection seems to be shaped by social and environmental factors. Research is needed to inform firm recommendations on how to protect this vulnerable population.

HandiVIH--A population-based survey to understand the vulnerability of people with disabilities to HIV and other sexual and reproductive health problems in Cameroon: protocol and methodological considerations.

INTRODUCTION: In resource-limited countries, people with disabilities seem to be particularly vulnerable to HIV infection due to barriers to accessing information and services, frequent exposure to sexual violence and social exclusion. However, they have often been left behind in the HIV response, probably because of the lack of reliable epidemiological data measuring this vulnerability. Multiple challenges in conducting good quality epidemiological surveys on people with disabilities require innovative methods to better understand the link between disability and HIV. This paper describes how the design and methods of the HandiVIH study were adapted to document the vulnerability of people with disabilities to HIV, and to compare their situation with that of people without disabilities. METHODS AND ANALYSIS: The HandiVIH project aims to combine quantitative and qualitative data. The quantitative component is a cross-sectional survey with a control group conducted in Yaoundé (Cameroon). A two-phase random sampling is used (1) to screen people with disabilities from the general population using the Washington Group questionnaire and, (2) to create a matched control group. An HIV test is proposed to each study participant. Additionally, a questionnaire including a life-event interview is used to collect data on respondents' life-course history of social isolation, employment, sexual partnership, HIV risk factors and fertility. Before the cross-sectional survey, a qualitative exploratory study was implemented to identify challenges in conducting the survey and possible solutions. Information on people with disabilities begging in the streets and members of disabled people's organisations is collected separately. ETHICS AND DISSEMINATION: This study has been approved by the two ethical committees. Special attention has been paid on how to adapt the consenting process to persons with intellectual disabilities. The methodological considerations discussed in this paper may contribute to the development of good practices for conducting quantitative health surveys on people with disabilities. TRIAL REGISTRATION NUMBER: NCT02192658.

Disability and HIV: a systematic review and a meta-analysis of the risk of HIV infection among adults with disabilities in Sub-Saharan Africa.

More than one billion people worldwide are estimated to be living with a disability. A significant proportion of them lives in Sub-Saharan Africa where they are reported to be at increased risk of HIV. However, quantitative evidence on this remains scarce. A systematic review and a meta-analysis of the risk of HIV infection among people with disabilities living in Sub-Saharan Africa were undertaken. We searched all published or unpublished studies and national surveys reporting HIV prevalence among adults with disabilities living in Sub-Saharan Africa between 2000 and 2013. The risk ratio (RR) of HIV infection in people with disabilities versus people without disabilities was estimated through a random-effects meta-analysis. Of the 12,252 references screened, 13 studies were selected. HIV prevalence varied widely across studies from 1.1% to 29%. Pooled RRs of HIV infection in people with disabilities compared to the general population were 1.31 (1.02-1.69) overall; 1.16 (0.71-1.87) among people with mental illness or intellectual disabilities and 1.07 (0.58-1.95) among people with hearing disabilities. This meta-analysis provides evidence that people with disabilities do not have a lower risk of HIV when compared to the general population, and that women with disabilities are especially affected. A clear increasing gradient in the risk of HIV according to gender and disability status was also observed. The important heterogeneity across studies and their varying quality warrant a closer look at the intersection between disability and HIV. Additional studies with more systematic approaches and with higher-quality methodologies are required to further address this knowledge gap.

Participative decentralization of diabetes care in Davao City (Philippines) according to the Chronic Care Model: a program evaluation.

AIM: To assess the effectiveness of the Diabetes Project in Davao City, Philippines, regarding diabetes care access, diabetes management and cardiovascular risk factors. The project was developed in accordance with the Chronic Care Model (CCM) framework. METHODS: A non-randomized cross-sectional survey was conducted in nine intervention and five control Barangays (villages). People with diabetes aged ≥20 years were interviewed using a structured questionnaire; height, weight, waist circumference, and blood pressure were measured; HbA1c was tested with a NSGP-certified point-of-care device. Logistic regression models were used to compare the two groups. RESULTS: The intervention group (n=503) scored better than the controls (n=136) on the following (OR, 95% CI): percentage of patients taking metformin (1.5, 1.0-2.2); and in the last 12 months: laboratory test for fasting blood sugar (1.6, 1.1-2.3), HbA1c (6.0, 2.4-15.1), lipid profile (1.7, 1.1-2.5), nutritionist visit (1.6, 1.0-2.5) and therapeutic education session (2.7, 1.8-4.0). Glycemic control (HbA1c<7%) was also better in the intervention Barangays (1.6, 1.0-2.4). There were no statistical differences between the two groups for number of visits, and levels of other cardiovascular risk factors. CONCLUSIONS: Our findings support the effectiveness of implementing the CCM framework in a low-to-middle income country on glycemic control and diabetes management.
