INTRODUCTION
Tuberculosis (TB) is an important cause of morbidity and mortality in children and over 50% of childhood TB remains undiagnosed every year. As microbiological confirmation is low (<30%), the majority of cases in low and middle-income countries are diagnosed on clinical grounds. Point-of-care ultrasound (POCUS) is a non-invasive bedside tool, and TB-focused POCUS has been validated for diagnosis of TB in adults with HIV. We aimed to describe the performance and findings of TB-focused POCUS for children with presumptive TB at a tertiary care hospital in Guinea- Bissau, a setting with a high burden of HIV, malnutrition and TB.
METHODS
This observational study took place at Simão Mendes hospital in Bissau, from July 2019 to April 2020. Patients aged between 6 months and 15 years with presumptive TB underwent clinical and laboratory assessment, with at least one sample analysed with GeneXpert Ultra, and unblinded clinician-performed POCUS evaluation. POCUS was used to assess for subpleural nodules (SUN’s), lung consolidation, pleural effusion, pericardial effusion, ascites, liver and splenic focal lesions, and abdominal lymph nodes. Presence of any of these signs prompted a POCUS- positive result. Images and clips were evaluated by an expert reviewer and, if discordant, by a second expert reviewer.
ETHICS
This study was approved by the MSF Ethics Review Board (ERB) and by the Guinea-Bissau Ministry of Health ERB.
RESULTS
A total of 139 children were enrolled, with 62 (45%) female and 55 (40%) aged under 5 years. HIV infection and severe acute malnutrition (SAM) were found in 59 (42%) and 83 (60%) of patients, respectively. Confirmation of TB was achieved in 27 (19%); 62 (45%) had unconfirmed TB, and 50 (36%) had unlikely TB. Children with TB were more likely to have a POCUS positive result (83/89; 93%) as compared to children with unlikely TB (17/50; 34%). The most common POCUS signs in TB patients were: lung consolidation (51; 57%), SUN’s (49; 55%), pleural effusion (27; 30%), and focal splenic lesions (25; 28%). In children with confirmed TB (n=27), POCUS sensitivity was 85.2% (95% confidence interval (CI) 67.5-94.1). In those with unlikely TB (n=50), specificity was 66% (95%CI 2.2-77.6). Unlike HIV infection, SAM was associated with higher risk of positive POCUS. Cohen’s kappa coefficient for concordance between field and expert reviewers ranged from 0.6 to 0.9 depending on the POCUS sign, while overall POCUS concordance was 0.8.
CONCLUSION
We found high prevalence of any POCUS sign in children with TB, as compared to children with unlikely TB. POCUS positivity was independent of HIV status, but not of nutritional status. POCUS concordance between field and expert reviewers was moderate to high. TB-focused POCUS could potentially play a supportive role in the diagnosis of TB in children.

INTRODUCTION
Effective palliative care requires a multidisciplinary and holistic approach based on the provision of comprehensive care with treatment of pain and physical symptoms, management of psychosocial needs, as well as other non-medical needs. Few studies exist about palliative care in India, particularly in the context of people living with HIV/AIDS. MSF supports an advanced HIV inpatient ward in Bihar, where mortality rates are high. We aimed to explore the lived experiences of palliative care among patients, and their families, with advanced HIV, to understand conceptions of illness, death, and end-of-life care in Bihar, India.
METHODS
We carried out an exploratory, qualitative study using 21 semi-structured in-depth interviews and 1 focus group discussion. Participants included patients living with HIV/AIDS (PLHA), caregivers, relatives of deceased patients who had been treated in a government hospital, and key informants from community-based organizations in Patna, Bihar. Interview data were transcribed verbatim, translated from Hindi or other local languages into English by research assistants, and analysed using NVIVO (QSR International, Victoria, Australia). Two researchers then carried out inductive, thematic analysis of the data. Emergent codes and categories were identified and compared to subsequent areas of inquiry.
ETHICS
This study was approved by the ethics committee of the All India Institute of Medical Sciences, Patna, India, and the MSF Ethics Review Board.
RESULTS
Latent thematic analysis revealed poor understanding of palliative care among advanced HIV patients and their caregivers; the term “palliative care” was not known to PLHA. PLHA and relatives expected active treatment, despite poor prognosis, and believed that dying patients should be provided a separate, private inpatient area. However, patients were able to identify the importance of psychosocial counselling, the desire for a separate dedicated space for terminal patients with social and recreational activities to prevent isolation, and a preference for home-based palliative care wherever possible. Our data showed that relatives of patients played a substantial role in influencing doctors and nurses to avoid divulging the nature of the disease and prognosis directly to patients. There was variation in preferences for open disclosure of prognosis amongst critically ill PLHA and relatives of deceased patients.
CONCLUSION
There is a need to improve palliative care provision for advanced HIV patients in Bihar, who do not typically have access to such services. PLHA should have a separate dedicated area, with adequate psychosocial counselling for patients and families, and regular recreational activities to prevent social isolation.

INTRODUCTION
People co-infected with visceral leishmaniasis and HIV (VL-HIV) typically present with advanced HIV disease and in poor clinical condition. The reasons for this are complex, but one major challenge relates to difficulties in ensuring early diagnosis of VL, a stage IV opportunistic infection, in the context of HIV. In VL-endemic areas, it is recognised that between 2 and 20% of the general population may harbour asymptomatic Leishmania infection (ALI), the vast majority of whom will not progress to symptomatic disease. However, similar data are absent for people living with HIV (PLHIV) in South Asia. Being able to diagnose ALI may provide a screen-and-treat opportunity to prevent progression to the fatal symptomatic form. We investigated the prevalence and determinants of ALI in PLHIV living in VL-endemic areas, and the risk of progression to symptomatic VL.
METHODS
We conducted a cross-sectional survey, enrolling PLHIV aged ≥18 with no diagnosis of or history of leishmaniasis symptoms, at three antiretroviral therapy centres within VL-endemic regions of Bihar, India. ALI was defined as a positive rK39 enzyme-linked immunosorbent assay (ELISA), rK39 rapid diagnostic test (RDT), and/or quantitative polymerase chain reaction (qPCR) result on blood. In addition, we tested for the Leishmania antigen in urine using ELISA as a novel non-invasive alternative. Participants were followed up at three-monthly intervals over 18 months to assess status and progression to symptomatic infection.
ETHICS
This study was approved by the ethics boards of the Rajendra Memorial Research Institute of Medical Sciences, Patna, India, and Liverpool School of Tropical Medicine, UK, and the MSF Ethics Review Board. Clinical Trial Registry-India number, CTRI/2017/03/008120.
RESULTS
1,296 PLHIV were included in the analysis. The baseline prevalence of ALI was 7.4% (n=96). All were found positive using rK39 ELISA, while 0.5% (n=6) and 0.4% (n=5) were positive using qPCR and rK39 RDT, respectively. 2.2% (n=28) patients were positive using urinary Leishmania antigen ELISA testing. Independent risk factors (p<0.05) for ALI were CD4 count <100 cells/mm3 (adjusted odds ratio, aOR, 3.1; 95%CI 1.2-7.6), and CD4 count between 100-199 cells/mm3 (aOR=2.1; 95%CI 1.1-4.0), as compared to CD4 ≥300 cells/mm3 and living in a household size ≥5 (aOR=1.8; 95%CI 1.1-3.2). Concordance between diagnostic tests was poor. A total of 109 asymptomatic patients were followed up prospectively, including 13 additional patients who were identified during pilot testing. Overall, 3.7% (n=4) patients converted from asymptomatic to symptomatic infection over the study period. Conversion rates of participants identified as positive using rK39 ELISA, rK39 RDT, qPCR, and urinary Leishmania antigen ELISA, were 3.7% (4/109), 40% (2/5), 57% (4/7), and 14% (4/29), respectively. Risk of all-cause mortality in those with ALI over 18 months’ follow-up was 6.4% (n=7), compared with 2.5% (n=30) in those without (risk ratio, 2.6, 95%CI 1.2-5.7, p=0.018).
CONCLUSION
PLHIV living in highly VL-endemic areas have a relatively high prevalence of ALI. Although progression rates to symptomatic infection appear low, all-cause mortality rates are higher and may reflect the impact of sub-clinical infection on HIV outcomes. The results may justify further studies investigating early treatment of ALI in PLHIV.

Introduction: National AIDS Programme in Myanmar has made significant progress in scaling up antiretroviral treatment (ART) services and recognizes the importance of differentiated care for people living with HIV. Indeed, long centred around the hospital and reliant on physicians, the country’s HIV response is undergoing a process of successful decentralization with HIV care increasingly being integrated into other health services as part of a systematic effort to expand access to HIV treatment. This study describes implementation of differentiated care in Médecins Sans Frontières (MSF)-supported programmes and reports its outcomes. Methods: A descriptive cohort analysis of adult patients on antiretroviral treatment was performed. We assessed stability of patients as of 31 December 2014 and introduced an intervention of reduced frequency of physicians’ consultations for stable patients, and fast tract ART refills. We measured a number of saved physician’s visits as the result of this intervention. Main outcomes, remained under care, death, lost to follow up, treatment failure, were assessed on 31 December 2015 and reported as rates for different stable groups. Results: On 31 December 2014, our programme counted 16, 272 adult patients enrolled in HIV care, of whom 80.34% were stable. The model allowed for an increase in the average number of patients one medical team could care for – from 745 patients in 2011 to 1, 627 in 2014 – and, thus, a reduction in the number of teams needed. An assessment of stable patients enrolled on ART one year after the implementation of the new model revealed excellent outcomes, aggregated for stable patients as 98.7% remaining in care, 0.4% dead, 0.8% lost to follow-up, 0.8% clinical treatment failure and 5.8% with immunological treatment failure. Conclusions: Implementation of a differentiated model reduced the number of visits between stable clients and physicians, reduced the medical resources required for treatment and enabled integrated treatment of the main co-morbidities. We hope that these findings will encourage other stakeholders to implement innovative models of HIV care in Myanmar, further expediting the scale up of ART services, the decentralization of treatment and the integration of care for the main HIV co-morbidities in this context.
