: A multicentric, retrospective case-series analysis (facility-based) in five sites across Kenya, Malawi, Mozambique, and Uganda screened HIV-positive adults for hepatitis C virus (HCV) antibodies using Oraquick rapid testing and viral confirmation (in three sites). Results found substantially lower prevalence than previously reported for these countries compared with previous reports, suggesting that targeted integration of HCV screening in African HIV programs may be more impactful than routine screening.This is an open access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

In sub-Saharan Africa models of care need to adapt to support continued scale up of antiretroviral therapy (ART) and retain millions in care. Task shifting, coupled with community participation has the potential to address the workforce gap, decongest health services, improve ART coverage, and to sustain retention of patients on ART over the long-term. The evidence supporting different models of community participation for ART care, or community-based ART, in sub-Saharan Africa, was reviewed. In Uganda and Kenya community health workers or volunteers delivered ART at home. In Mozambique people living with HIV/AIDS (PLWHA) self-formed community-based ART groups to deliver ART in the community. These examples of community ART programs made treatment more accessible and affordable. However, to achieve success some major challenges need to be overcome: first, community programs need to be driven, owned by and embedded in the communities. Second, an enabling and supportive environment is needed to ensure that task shifting to lay staff and PLWHA is effective and quality services are provided. Finally, a long term vision and commitment from national governments and international donors is required. Exploration of the cost, effectiveness, and sustainability of the different community-based ART models in different contexts will be needed.

BACKGROUND
The novel point-of-care urine-based FujiLAM test is promising for diagnosis of tuberculosis. We assessed the diagnostic yield of FujiLAM in HIV patients and the feasibility of using the test.
METHODS
We conducted a prospective diagnostic study and a mixed-methods feasibility and acceptability study in 4 countries: Uganda, Kenya,
Mozambique and South Africa. The diagnostic study included 2 groups of ambulatory HIV-positive adults: 1) with TB symptoms, 2) with advanced HIV disease and no TB symptoms. Patients received FujiLAM and AlereLAM, Xpert MTB/RIF, culture and chest X-ray. The feasibility study included test’ users, key informants and patients who participated through standard questionnaires, individual interviews and group discussions.
RESULTS
We included 1117 patients in the diagnostic study: 712 with TB symptoms (Group 1) and 405 with advanced HIV disease and no TB
symptoms (Group 2). TB was confirmed in 9.2% (63/685) and 4.1% (16/395) in Group 1 and 2, respectively. FujiLAM diagnostic yield among patients with confirmed TB was 63.2% and 43.8% in Group 1 and 2, respectively. FujiLAM diagnostic yield by CD4 count was: 75.0% in CD4<200, 77.8% in CD4 200-349, 31.3% in CD4≥350 (Group 1) and 46.7% in CD4<200 (Group 2). Most of the test users (including lay health workers) found FujiLAM easy to perform. The main concern was the multiple timed steps involved. Invalid results were obtained if test cartridges were dropped or performed on blood stained or cloudy urine. Most patients viewed urine sampling
positively and easier than sputum provision.
CONCLUSIONS
FujiLAM detects TB in a high proportion of the HIV patients with confirmed TB who have symptoms of TB and low CD4 counts, and in
a considerable proportion of those asymptomatic. The test is easy to perform at point-of-care. Urine sampling is well accepted by patients. These results encourage the future use of the FujiLAM assay.
KEY MESSAGES: The novel urine-based FujiLAM is a useful and easy to use point-of care test for TB diagnosis in HIV-positive patients. Urine sampling is well accepted.

Kaposi's sarcoma (KS) is a common HIV-associated malignancy associated with disability, pain and poor outcomes. The cornerstone of its treatment is antiretroviral therapy, but advanced disease necessitates the addition of chemotherapy. In high-income settings, this often consists of liposomal anthracyclines, but in Mozambique, the first line includes conventional doxorubicin, bleomycin and vincristine, which is poorly-tolerated. Médecins Sans Frontières supports the Ministry of Health (MOH) in a specialized HIV and KS treatment center at the Centro de Referencia de Alto Maé in Maputo.

MSF Scientific Days International 2021: Innovation. 2021 May 20
WHAT CHALLENGE OR OPPORTUNITY DID YOU TRY TO ADDRESS? WERE EXISTING SOLUTIONS NOT AVAILABLE OR NOT GOOD ENOUGH?
Ototoxicity is an unfortunate side-effect of second-line injectable drugs for drug-resistant tuberculosis (DRTB), including aminoglycosides and peptides. Worldwide, up to 15% of patients on treatment regimens containing these drugs develop a degree of ototoxicity. Patients who experience ototoxicity are generally switched to an oral treatment regimen. Although regular audiological evaluations are recommended for patients receiving these drugs, there is limited access to these services, and few patients with noticeable hearing problems are referred for confirmation and follow-up.
WHY DOES THIS CHALLENGE OR OPPORTUNITY MATTER – WHY SHOULD MSF ADDRESS IT?
Before the introduction of this digital tool, the MSF DRTB project in Mozambique had to refer patients to the Central Hospital in Maputo. This limited the number of patients screened and referred for testing, curtailing the potential to switch treatment early for those showing mild-to-moderate hearing loss.
DESCRIBE YOUR INNOVATION AND WHAT MAKES IT INNOVATIVE
In 2018, the team piloted a way to simplify monitoring of hearing using a clinically approved mobile tablet-based tool that has been found to be comparable with traditional audiometry measurements in children and adults. MSF acquired three kits of CE-marked and FDA-certified iOS-based audiometry kits from SHOEBOX® Audiometry systems. The units were comprised of calibrated headphones and tablet-based software that have acceptable accuracy (±10dB) with 90% sensitivity and specificity. The portable units were deployed in rotation in six health centres over two years; a total of 673 audiometry tests were performed in MSF-supported public health centres in Maputo. Patients were tested at baseline during their first consultation and then monthly while on treatment regimens that included injectable drugs.
WHO WILL BENEFIT (WHOSE LIFE / WORK WILL IT IMPROVE?) AND WERE THEY INVOLVED IN THE DESIGN?
The 2018 Mozambique National TB Committee approved treatment without injectable drugs in patients who had any degree of hearing impairment before the initiation of treatment. Patients screened using the digital tool directly benefitted from switching to oral DRTB treatment if they exhibited any hearing loss, without requiring hospital referral.
WHAT OBJECTIVES DID YOU SET FOR THE PROJECT – WHAT DID YOU WANT TO ACHIEVE AND HOW DID YOU DEFINE AND MEASURE SUCCESS (IMPROVED SERVICE, LOWER COST, BETTER EFFICIENCY, BETTER USER EXPERIENCE, ETC.)?
We describe the implementation and use of a mobile audiometry system for patients with treatment-related ototoxicity in the MSF DRTB project in Mozambique, and consider its potential for easily assessing hearing deterioration in this cohort.
WHAT DATA DID YOU COLLECT TO MEASURE THE INNOVATION AGAINST THESE INDICATORS AND HOW DID YOU COLLECT IT? INCLUDE IF YOU DECIDED TO CHANGE THE INDICATORS AND WHY
Routinely collected data were evaluated.
WERE THERE ANY LIMITATIONS TO THE DATA YOU COLLECTED, HOW YOU COLLECTED IT OR HOW YOU ANALYSED IT, OR WERE THERE ANY UNFORESEEN FACTORS THAT MAY HAVE INTERFERED WITH YOUR RESULTS?
Data were analysed retrospectively from routine records and may not be exhaustive. Separate analysis of baseline and follow-up was not possible.
WHAT RESULTS DID YOU GET?
Of the 673 audiometry tests conducted using the digital tool, 480 (71%) showed normal hearing, 65 (10%) mild hearing loss, 81 (12%) moderate hearing loss, and 47 (7%) severe-to-profound hearing loss.
COMPARING THE RESULTS FROM YOUR DATA ANALYSIS TO YOUR OBJECTIVES, EXPLAIN WHY YOU CONSIDER YOUR INNOVATION A SUCCESS OR FAILURE?
This decentralised approach does not need specialised setup, which may lead to increased screening, proper follow-up, and more potential for early switching of drug regimens.
TO WHAT EXTENT DID THE INNOVATION BENEFIT PEOPLE’S LIVES / WORK?
Decreasing the need for hospital referrals improved time and transport costs for patients.
IS THERE ANYTHING THAT YOU WOULD DO DIFFERENTLY IF YOU WERE TO DO THE WORK AGAIN?:
A cost-benefit analysis to compare the mobile audiometry system to referrals would be beneficial for programmatic decisions.
WHAT ARE THE NEXT STEPS FOR THE INNOVATION ITSELF (SCALE UP, IMPLEMENTATION, FURTHER DEVELOPMENT, DISCONTINUED)?
In December 2019, the project was phased out as there was a protocol change in which injectable drugs were replaced with more potent and fully oral regimens that made monitoring for ototoxicity unnecessary for most patients.
IS THE INNOVATION TRANSFERABLE OR ADAPTABLE TO OTHER SETTINGS OR DOMAINS?
The tools adapted are clinically approved for screening activities for any programmes that deal with hearing loss.
WHAT BROADER IMPLICATIONS ARE THERE FROM THE INNOVATION FOR MSF AND / OR OTHERS (CHANGE IN PRACTICE, CHANGE IN POLICY, CHANGE IN GUIDELINES, PARADIGM SHIFT)?
The project demonstrates the potential to improve follow-up and detect complications early for patients who take ototoxic medications.
WHAT OTHER LEARNINGS FROM YOUR WORK ARE IMPORTANT TO SHARE?
User-friendly and automated audiometry systems that are mobile and do not require audiologists or sound-insulated booths could be extremely useful to various medical projects using potentially ototoxic drugs such as aminoglycosides. They may also be beneficial for environmental projects with noise and toxic pollutions. The high cost of the license could present a limitation necessitating a cost-benefit analysis before contemplating scale-up.

We conducted a study to assess the feasibility and the potential vaccine coverage of a mass vaccination campaign using a two-dose oral cholera vaccine in an urban endemic neighbourhood of Beira, Mozambique. The campaign was conducted from December 2003 to January 2004. Overall 98,152 doses were administered, and vaccine coverage of the target population was 58.6% and 53.6% for the first and second rounds, respectively. The direct cost of the campaign, which excludes the price of the vaccine, amounted to slightly over 90,000 dollars, resulting in the cost per fully vaccinated person of 2.09 dollars, which is relatively high. However, in endemic settings where outbreaks are likely to occur, integrating cholera vaccination into the routine activities of the public health system could reduce such costs.

Mozambique continues to face many challenges in HIV and maternal and child health care (MCH). Community-based antiretroviral treatment groups (CAG) enhance retention to care among members, but whether such benefits extend to their families and to MCH remains unclear. In 2011 we studied utilization of HIV and MCH services among CAG members and their family aggregates in Changara, Mozambique, through a mixed-method assessment. We systematically revised all patient-held health cards from CAG members and their non-CAG family aggregate members and conducted semistructured group discussions on MCH topics. Quantitative data were analysed in EPI-Info. Qualitative data were manually thematically analysed. Information was retrieved from 1,624 persons, of which 420 were CAG members (26%). Good compliance with HIV treatment among CAG members was shared with non-CAG HIV-positive family members on treatment, but many family aggregate members remained without testing, and, when HIV positive, without HIV treatment. No positive effects from the CAG model were found for MCH service utilization. Barriers for utilization mentioned centred on insufficient knowledge, limited community-health facility collaboration, and structural health system limitations. CAG members were open to include MCH in their groups, offering the possibility to extend patient involvement to other health needs. We recommend that lessons learnt from HIV-based activism, patient involvement, and community participation are applied to broader SRH services, including MCH care.

BACKGROUND
The novel urine-based FujiLAM test identifies tuberculosis in HIV-positive patients but may be challenging to use at point-of-care (POC).
OBJECTIVES
We assessed the feasibility and acceptability of using the FujiLAM test at the point of care in outpatient settings.
METHODS
We conducted a mixed-methods study in four outpatient settings in Kenya, Mozambique, South Africa, and Uganda between November 2020 and September 2021. The test was performed at POC in existing clinic laboratories and consultation spaces. We performed direct observations in the four health facilities, individual questionnaires, proficiency testing evaluations, and individual interviews among healthcare workers performing the FujiLAM test (healthcare workers), and group discussions with programme managers.
RESULTS
Overall, 18/19 (95%) healthcare workers and 14/14 (100%) managers agreed to participate in the study. Most assessed healthcare workers, including lay health workers (10/11; 91%), met the minimum required theoretical knowledge and practical skill in performing the FujiLAM test. Most healthcare workers (17/18; 94%) found the FujiLAM test overall “Easy/Very easy” to perform. Some challenges were mentioned: many timed steps (5/18; 28%); ensuring correct incubation period (5/18; 28%); test result readability (4/18; 22%); and difficulties with cartridge buttons (3/18; 17%). Half of the healthcare workers regularly performing the test (4/7; 57%) found it “Easy” to integrate into routine activities. Most healthcare workers and managers believed that any healthcare worker could perform the test after adequate training.
CONCLUSIONS
Implementing the FujiLAM test in outpatient POC settings is feasible and acceptable to healthcare workers and managers. This test can be performed in various clinic locations by any healthcare worker. The timed, multi-step test procedure is challenging and may affect the workload in resource-constrained health facilities.

BACKGROUND
In countries with a high incidence of HIV and tuberculosis co-infection, nevirapine and efavirenz are widely used as antiretroviral therapy but both interact with antituberculosis drugs. We aimed to compare efficacy and safety of a nevirapine-based antiretroviral therapy (started at full dose) with an efavirenz-based regimen in co-infected patients.
METHODS
We did a multicentre, open-label, randomised, non-inferiority trial at three health centres in Maputo, Mozambique. We enrolled adults (≥18 years) with tuberculosis and previously untreated HIV infection (CD4 cell counts <250 cells per μL) and alanine aminotransferase and total bilirubin concentrations of less than five times the upper limit of normal. 4-6 weeks after the start of tuberculosis treatment, we randomly allocated patients (1:1) with central randomisation, block sizes of two to six, and stratified by site and CD4 cell count to nevirapine (200 mg twice daily) or efavirenz (600 mg once daily), plus lamivudine and stavudine. The primary endpoint was virological suppression at 48 weeks (HIV-1 RNA <50 copies per mL) in all patients who received at least one dose of study drug (intention-to-treat population); death and loss to follow-up were recorded as treatment failure. The non-inferiority margin for the difference of efficacy was 10%. We assessed efficacy in intention-to-treat and per-protocol populations and safety in all patients who received study drug. This study is registered with ClinicalTrials.gov, number NCT00495326.
FINDINGS
Between October, 2007, and March, 2010, we enrolled 285 patients into each group. 242 (85%) patients in the nevirapine group and 233 (82%) patients in the efavirenz group completed follow-up. In the intention-to-treat population, 184 patients (64·6%, 95% CI 58·7-70·1) allocated nevirapine achieved virological suppression at week 48, as did 199 patients (69·8%, 64·1-75·1) allocated efavirenz (one-sided 95% CI of the difference of efficacy 11·7%). In the per-protocol population, 170 (70·0%, 63·8-75·7) of 243 patients allocated nevirapine achieved virological suppression at week 48, as did 194 (78·9%, 73·2-83·8) of 246 patients allocated efavirenz (one-sided 95% CI 15·4%). The median CD4 cell count at randomisation was 89 cells per μL. 15 patients substituted nevirapine with efavirenz and six patients substituted efavirenz with nevirapine. 20 patients allocated nevirapine (7%) had grade 3-4 increase of alanine aminotransferase compared with 17 patients allocated efavirenz (6%). Three patients had severe rash after receipt of nevirapine (1%) but no patients did after receipt of efavirenz. 18 patients in the nevirapine group died, as did 17 patients in the efavirenz group.
INTERPRETATION
Although non-inferiority of the nevirapine-regimen was not shown, nevirapine at full dose could be a safe, acceptable alternative for patients unable to tolerate efavirenz. FUNDING: French Research Agency for HIV/AIDS and hepatitis (ANRS).

The median CD4 cell count at randomisation was 89 cells per μL. 15 patients substituted nevirapine with efavirenz and six patients substituted efavirenz with nevirapine. 20 patients allocated nevirapine (7%) had grade 3-4 increase of alanine aminotransferase compared with 17 patients allocated efavirenz (6%). Three patients had severe rash after receipt of nevirapine (1%) but no patients did after receipt of efavirenz. 18 patients in the nevirapine group died, as did 17 patients in the efavirenz group.
INTERPRETATION
Although non-inferiority of the nevirapine-regimen was not shown, nevirapine at full dose could be a safe, acceptable alternative for patients unable to tolerate efavirenz. FUNDING: French Research Agency for HIV/AIDS and hepatitis (ANRS).

BACKGROUND
Cholera remains a public health threat but is inequitably distributed across sub-Saharan Africa. Lack of standardized reporting and inconsistent outbreak definitions limit our understanding of cholera outbreak epidemiology.
METHODS
From a database of cholera incidence and mortality, we extracted data from sub-Saharan Africa and reconstructed outbreaks of suspected cholera starting in January 2010 to December 2019 based on location-specific average weekly incidence rate thresholds. We then described the distribution of key outbreak metrics.
RESULTS
We identified 999 suspected cholera outbreaks in 744 regions across 25 sub-Saharan African countries. The outbreak periods accounted for 1.8 billion person-months (2% of the total during this period) from January 2010 to January 2020. Among 692 outbreaks reported from second-level administrative units (e.g., districts), the median attack rate was 0.8 per 1000 people (interquartile range (IQR), 0.3-2.4 per 1000), the median epidemic duration was 13 weeks (IQR, 8-19), and the median early outbreak reproductive number was 1.8 (range, 1.1-3.5). Larger attack rates were associated with longer times to outbreak peak, longer epidemic durations, and lower case fatality risks.
CONCLUSIONS
This study provides a baseline from which the progress toward cholera control and essential statistics to inform outbreak management in sub-Saharan Africa can be monitored.
