This is a descriptive report of a pilot project of tuberculosis (TB) treatment in a conflict zone. A TB programme was implemented by Médecins Sans Frontières(MSF)-Holland in a semi-nomadic population in a very insecure and underdeveloped area of Upper Nile province in Southern Sudan. Outcome measures were operational feasibility, default rate, and sputum smear conversion at 4 months. A cohort of TB patients was admitted over a 10-week period (July-September 2001). Adherence strategy, project implementation, and and contingency planning were adapted to local conditions. The treatment regimen (4 HRZE [4-month daily supervised regimen] followed by 3EH or 3TH [3-month unsupervised regimen]: isoniazid (H), rifampicin (R), pyrazinamide (Z), ethambutol (E) and thiacetazone (T)) was a variant on the Manyatta regimen developed for semi-nomads in Kenya. Of 163 patients, 84 (52%) were children aged < 15 years. Lymph node TB comprised 34% and spinal TB 15% of all patients. Among adults, 41% had smear-positive pulmonary disease. Only 1 patient (0.6%) defaulted. All sputum smear-positive patients who completed 4 months of therapy converted to smear-negative, although 2 were subsequently found to have relapsed. TB in complex emergency situations is an underrecognized priority. Using an approach adapted especially to this setting, TB treatment was successfully implemented with minimal risk of promoting drug resistance, in an unstable setting.

The current first-line and second-line drugs for Plasmodium falciparum malaria in South Sudan, chloroquine and sulfadoxine-pyrimethamine (SP), were evaluated and compared with amodiaquine, in an MSF-Holland-run clinic in eastern Upper Nile, South Sudan from June to December 2001. Patients with uncomplicated malaria and fever were stratified by age group and randomly allocated to one of 3 treatment regimes. A total of 342 patients was admitted and followed for 14 d after treatment. The dropout rate was 10.2%. Of those who completed the study, 104 were treated with chloroquine (25 mg/kg, 3 d), 102 with SP (25 mg/kg sulfadoxine and 1.25 mg/kg pyrimethamine, single dose) and 101 with amodiaquine (25 mg/kg, 3 d). Adequate clinical response was observed in 88.5% of patients treated with chloroquine, 100% of patients treated with SP and 94.1% of patients treated with amodiaquine. In children aged < 5 years, the success rate was lower: 83.3% for chloroquine and 93.0% for amodiaquine. In adults no treatment failures were found, but children aged 5-15 years showed intermediate levels. In addition, we determined the initial genotypes of dhfr and dhps of 44 isolates from the SP-treated group and > 80% were found to be wild type for dhfr and 100% for dhps. Two percent of isolates had a single mutation and 16% had double mutations of dhfr. These data are in full agreement with the clinical effectiveness of SP. A change in malaria treatment protocols for South Sudan is recommended.

OBJECTIVES
To describe the effect of adaptations to a person-centred care with short oral regimens on retention in care for rifampicin-resistant TB (RR-TB) in Kandahar province, Afghanistan.
METHODS
The study included people with RR-TB registered in the programme between 01 October 2016 and 18 April 2021. From 19 November 2019, the programme implemented a trial investigating the safety and effectiveness of short oral RR-TB regimens. During the trial, person-centred care was adapted. We included the data from people living with RR-TB treated in the period before and after the care model was adapted and applied Kaplan-Meier statistics to compare rates of retention in care.
RESULTS
Of 236 patients registered in the RR-TB programme, 146 (61.9%) were registered before and 90 (38.1%) after the model of care was adapted. Before adaptations enhancing person-centred care, pre-treatment attrition was 23.3% (n = 34/146), whilst under the adapted care model it was 5.6% (n = 5/90). Attrition on treatment was 22.3% (n = 25/112) before adaptations, whilst during the study period none of the participants were lost-to-follow-up on treatment and 3.3% died (n = 3/90).
CONCLUSIONS
As person-centred care delivery and treatment regimens were adapted to better fit-specific contextual challenges and the needs of the target population, retention in care improved amongst people with RR-TB in Kandahar, Afghanistan.

Int J Tuberc Lung Dis. 2020 October 1; Volume 24; DOI:10.5588/ijtld.20.0082
SETTING: Since 2015, Eswatini has been scaling up bedaquiline (BDQ) and delamanid (DLM) based drug-resistant TB treatment regimens under programmatic conditions.
OBJECTIVE: Identification of factors associated with treatment outcomes in patients receiving BDQ and/or DLM either as a new treatment initiation or drug substitution.
DESIGN: This is a retrospective cohort study of patients receiving BDQ and/or DLM in Eswatini between March 2015 and October 2018. We describe factors associated with unfavourable treatment outcomes (death, lost to follow-up, treatment failure and amplification of resistance) and culture conversion using multivariable flexible parametric survival and competing-risks regression analyses.
RESULTS: Of 352 patients receiving BDQ and/or DLM, 7.8% and 21.2% had an unfavourable treatment outcome at 6 and 24 months, respectively. Predictors were age ≥ 60 years (adjusted hazard ratio aHR 4.49, 95%CI 1.61–12.57) vs. age 20–39 years, and a treatment regimen combining both drugs (aHR 4.49, 95%CI 1.61–12.57) vs. BDQ only. The probability of culture conversion was increased for two health facilities and patients with a poly resistance profile (adjusted sub-hazard ratio 2.01, 95%CI 1.13–3.59) vs. multidrug resistance.
CONCLUSION: Single use of BDQ or DLM was associated with low rates of unfavourable outcomes, suggesting that these medications may be effectively adopted at scale under routine programmatic conditions. Combined use of BDQ and DLM was a risk factor for unfavourable outcomes and should prompt for collection of more data on the combined use of these medications.

INTRODUCTION
In April 2020, “shielding” (separate living spaces with enhanced infection control support for groups at high risk of severe COVID-19 disease) was proposed for COVID-19 prevention in settings where lockdown is not feasible (i.e. displaced persons camps). MSF used qualitative methods to explore community perceptions of shielding and other potential COVID-19 prevention measures applicable in settings where it works. Nigeria and Sierra Leone served as initial pilot sites for this multi-site study that ultimately included 13 countries.
METHODS
We carried out qualitative assessments between April and August 2020 within 9 MSF-supported sites in Nigeria and Sierra Leone, with the aim of exploring community perceptions of potential COVID-19 prevention measures. Sites in Nigeria included internally displaced camps in two states, and in Sierra Leone, an open village setting. We conducted multiple rounds of participant-led individual in-depth qualitative interviews in the study sites between April-August 2020. We recruited participants purposively, ensuring participants recruited were representative of underlying demographic and ethnic diversity. Data were coded by hand on paper copies of transcripts and in NVivo12 and analyzed for key themes. Findings were built on through iteration with participants.
ETHICS
This study was approved by the MSF Ethics Review Board and by the Ethical Review Boards of Benue State, Nigeria, Zamfara State, Nigeria, and the District Health Management team,
Tonkolilli, Sierra Leone.
RESULTS
Participants reported that access to both COVID-19 and non- COVID-19 care was challenging due to fear of infection and practical difficulties attending care facilities. Key priorities noted
by participants included obtaining food, masks and handwashing, and continuing to get access to non-COVID-19 healthcare. In Nigeria, shielding (providing separate dwellings for high-risk
people) was described as a challenge.
Reasons for this included close living conditions affecting practicality, its impact on mental health, and the community’s inter-generational reliance. Shielding was only seen as feasible
with sustained provision of resources for shielded persons including COVID testing, food from the family, mobile phones, and socially distanced visitation. For Sierra Leone, previous
experiences (e.g. war, Ebola) influenced fears of separation and the possibility of infection from contact with strangers and health workers or health facilities. Lockdowns and school
closures have a negative effect on support networks and local economies, and in Sierra Leone increased the perceived risk of sexual and gender-based violence and exploitation. Participants reported the desire for self-management of contact tracing and transmission prevention activities within their communities. Context-specific activities to address these priorities were implemented in response.
CONCLUSION
The community-based feedback provided a better understanding of attitudes towards and feasibility of COVID-19 control measures. Commonalities were reported across sites, while
differences in findings across sites highlighted the importance of context-specific engagement. Early and continued community engagement allowed context-specific activities to address these priorities to be implemented in partnership with communities in response. Implemented activities included enhancement of handwashing points, subsidizing locally-produced cloth masks, and reinforcement of prevention and control for non-COVID diseases such as malaria.

INTRODUCTION
Since 2011 Médecins sans Frontières together with the eSwatini Ministry of Health have been managing patients with multi-drug resistant tuberculosis (MDR-TB) at Matsapha and Mankayane in Manzini region. This analysis describes the model of care and outcomes of patients receiving a 20 months MDR-TB treatment regimen between 2011 and 2013.
METHOD
We conducted a retrospective observational cohort study of MDR-TB patients enrolled for treatment between May 2011 and December 2013. An extensive package of psychological care and socio-economic incentives were provided including psychological support, paid treatment supporters, transport fees and a monthly food package. Baseline demographic details and treatment outcomes were recorded and for HIV positive patient's univariate analysis as well as a cox regression hazard model were undertaken to assess risk factors for unfavorable outcomes.
RESULTS
From the 174 patients enrolled, 156 (89.7%) were HIV co-infected, 102 (58.6%) were female, median age 33 years old (IQR: 28-42), 55 (31.6%) had a BMI less than 18 and 86 (49.4%) had not been previously treated for any form of TB. Overall cohort outcomes revealed a 75.3% treatment success rate, 21.3% mortality rate, 0.6% failure and 0.6% lost to follow-up rate. In the adjusted multivariate analysis, low BMI and low CD4 count at treatment initiation were associated with an increased risk of unfavorable outcome.
CONCLUSIONS
A model of care that included psychosocial support and patient's enablers led to a high level of treatment success with a very low lost to follow up rate. Limiting the overall treatment success was a high mortality rate which was associated with advanced HIV and a low BMI at presentation. These factors will need to be addressed in order to improve upon the overall treatment success rate in future.

Amodiaquine, a 4-aminoquinoline compound, is being considered as an alternative to chloroquine and pyrimethamine/sulfadoxine where resistance in Plasmodium falciparum to both drugs has been selected. Although amodiaquine is more potent than chloroquine, its effectiveness is reduced in areas where chloroquine resistance is high. We report an association of the P. falciparum chloroquine resistance transporter (pfcrt) gene and the P. falciparum multiple drug resistance 1 (pfmdr1) gene, two chloroquine resistance markers, with chloroquine and amodiaquine efficacy in vivo in southern Sudan. The data show that the allele of the pfcrt gene with a lysine to threonine change at codon 76 is strongly associated with both chloroquine and amodiaquine resistance. No such association was observed with the pfmdr1 gene.

An atypical outbreak of West Nile virus (WNV) occurred in Ngorban County, South Kordophan, Sudan, from May to August 2002. We investigated the epidemic and conducted a case-control study in the village of Limon. Blood samples were obtained for cases and controls. Patients with obvious sequelae underwent cerebrospinal fluid (CSF) sampling as well. We used enzyme-linked immunosorbent assay (ELISA) and neutralization tests for laboratory diagnosis and identified 31 cases with encephalitis, four of whom died. Median age was 36 months. Bivariate analysis did not reveal any significant association with the risk factors investigated. Laboratory analysis confirmed presence of IgM antibodies caused by WNV in eight of 13 cases, indicative of recent viral infection. The unique aspects of the WNW outbreak in Sudan, i.e. disease occurrence solely among children and the clinical domination of encephalitis, involving severe neurological sequelae, demonstrate the continuing evolution of WNV virulence. The spread of such a virus to other countries or continents cannot be excluded.
