    • The Continuing Value of CD4 Cell Count Monitoring for Differential HIV Care and Surveillance

      Rice, B; Boulle, A; Schwarcz, S; Shroufi, A; Rutherford, G; Hargreaves, J (JMIR Publications, 2019-03-20)
      The move toward universal provision of antiretroviral therapy and the expansion of HIV viral load monitoring call into question the ongoing value of CD4 cell count testing and monitoring. We highlight the role CD4 monitoring continues to have in guiding clinical decisions and measuring and evaluating the epidemiology of HIV. To end the HIV/AIDS epidemic, we require strategic information, which includes CD4 cell counts, to make informed clinical decisions and effectively monitor key surveillance indicators.
    • Antibiotic Resistance in Pacific Island Countries and Territories: A Systematic Scoping Review

      Foxlee, ND; Townell, N; McIver, L; Lau, CL (Multidisciplinary Digital Publishing Institute, 2019-03-19)
      Several studies have investigated antimicrobial resistance in low- and middle-income countries, but to date little attention has been paid to the Pacific Islands Countries and Territories (PICTs). This study aims to review the literature on antibiotic resistance (ABR) in healthcare settings in PICTs to inform further research and future policy development for the region. Following the PRISMA-ScR checklist health databases and grey literature sources were searched. Three reviewers independently screened the literature for inclusion, data was extracted using a charting tool and the results were described and synthesised. Sixty-five studies about ABR in PICTs were identified and these are primarily about New Caledonia, Fiji and Papua New Guinea. Ten PICTs contributed the remaining 21 studies and nine PICTs were not represented. The predominant gram-positive pathogen reported was community-acquired methicillin resistant S. aureus and the rates of resistance ranged widely (>50% to <20%). Resistance reported in gram-negative pathogens was mainly associated with healthcare-associated infections (HCAIs). Extended spectrum beta-lactamase (ESBL) producing K. pneumoniae isolates were reported in New Caledonia (3.4%) and Fiji (22%) and carbapenem resistant A. baumannii (CR-ab) isolates in the French Territories (24.8%). ABR is a problem in the PICTs, but the epidemiology requires further characterisation. Action on strengthening surveillance in PICTs needs to be prioritised so strategies to contain ABR can be fully realised.
    • The burden of diabetes and use of diabetes care in humanitarian crises in low-income and middle-income countries

      Kehlenbrink, S; Smith, J; Ansbro, E; Fuhr, D; Cheung, A; Ratnayake, R; Boulle, P; Jobanputra, K; Perel, P; Roberts, B (Elsevier, 2019-03-13)
      Human suffering as a result of natural disasters or conflict includes death and disability from non-communicable diseases, including diabetes, which have largely been neglected in humanitarian crises. The objectives of this Series paper were to examine the evidence on the burden of diabetes, use of health services, and access to care for people with diabetes among populations affected by humanitarian crises in low-income and middle-income countries, and to identify research gaps for future studies. We reviewed the scientific literature on this topic published between 1992 and 2018. The results emphasise that the burden of diabetes in humanitarian settings is not being captured, clinical guidance is insufficient, and diabetes is not being adequately addressed. Crisis-affected populations with diabetes face enormous constraints accessing care, mainly because of high medical costs. Further research is needed to characterise the epidemiology of diabetes in humanitarian settings and to develop simplified, cost-effective models of care to improve the delivery of diabetes care during humanitarian crises.
    • Challenges associated with providing diabetes care in humanitarian settings

      Boulle, P; Kehlenbrink, S; Smith, J; Beran, D; Jobanputra, K (Elsevier, 2019-03-13)
      The humanitarian health landscape is gradually changing, partly as a result of the shift in global epidemiological trends and the rise of non-communicable diseases, including diabetes. Humanitarian actors are progressively incorporating care for diabetes into emergency medical response, but challenges abound. This Series paper discusses contemporary practical challenges associated with diabetes care in humanitarian contexts in low-income and middle-income countries, using the six building blocks of health systems described by WHO (information and research, service delivery, health workforce, medical products and technologies, governance, and financing) as a framework. Challenges include the scarcity of evidence on the management of diabetes and clinical guidelines adapted to humanitarian contexts; unavailability of core indicators for surveillance and monitoring systems; and restricted access to the medicines and diagnostics necessary for adequate clinical care. Policy and system frameworks do not routinely include diabetes and little funding is allocated for diabetes care in humanitarian crises. Humanitarian organisations are increasingly gaining experience delivering diabetes care, and interagency collaboration to coordinate, improve data collection, and analyse available programmes is in progress. However, the needs around all six WHO health system building blocks are immense, and much work needs to be done to improve diabetes care for crisis-affected populations.
    • Treatment outcomes of patients switching from an injectable drug to bedaquiline during short standardized MDR-TB treatment in Mozambique

      Bastard, M; Molfino, L; Mutaquiha, C; Galindo, MA; Zindoga, P; Vaz, D; Mahinca, I; du Cros, P; Rusch, B; Telnov, A (Oxford University Press, 2019-03-11)
      Bedaquiline was recommended by WHO as the preferred option in treatment of MDR-TB patients with long regimen. However, no recommendation was given for the short MDR-TB regimen. Data from our small cohort of patients who switched injectable dug to bedaquiline suggest that bedaquiline based short regimen is effective and safe.
    • Clinical Practice Guidelines for Chagas Disease: Recent Developments and Future Needs

      Forsyth, C; Marchiol, A; Herazo, R; Chatelain, E; Batista, C; Strub-Wourgraft, N; Bilbe, G; Sosa-Estani, S (Brazilian Society of Tropical Medicine, 2019-03-08)
    • Delays in arrival and treatment in emergency departments: Women, children and non-trauma consultations the most at risk in humanitarian settings

      Guzman, IB; Cuesta, JG; Trelles, M; Jaweed, O; Cherestal, S; van Loenhout, JAF; Guha-Sapir, D (Public Library of Science, 2019-03-05)
      Introduction Delays in arrival and treatment at health facilities lead to negative health outcomes. Individual and external factors could be associated with these delays. This study aimed to assess common factors associated with arrival and treatment delays in the emergency departments (ED) of three hospitals in humanitarian settings. Methodology This was a cross-sectional study based on routine data collected from three MSF-supported hospitals in Afghanistan, Haiti and Sierra Leone. We calculated the proportion of consultations with delay in arrival (>24 hours) and in treatment (based on target time according to triage categories). We used a multinomial logistic regression model (MLR) to analyse the association between age, sex, hospital and diagnosis (trauma and non-trauma) with these delays. Results We included 95,025 consultations. Males represented 65.2%, Delay in arrival was present in 27.8% of cases and delay in treatment in 27.2%. The MLR showed higher risk of delay in arrival for females (OR 1.2, 95% CI 1.2–1.3), children <5 (OR 1.4, 95% CI 1.4–1.5), patients attending to Gondama (OR 30.0, 95% CI 25.6–35.3) and non-trauma cases (OR 4.7, 95% CI 4.4–4.8). A higher risk of delay in treatment was observed for females (OR 1.1, 95% CI 1.0–1.1), children <5 (OR 2.0, 95% CI 1.9–2.1), patients attending to Martissant (OR 14.6, 95% CI 13.9–15.4) and non-trauma cases (OR 1.6, 95% CI 1.5–1.7). Conclusions Women, children <5 and non-trauma cases suffered most from delays. These delays could relate to educational and cultural barriers, and severity perception of the disease. Treatment delay could be due to insufficient resources with consequent overcrowding, and severity perception from medical staff for non-trauma patients. Extended community outreach, health promotion and support to community health workers could improve emergency care in humanitarian settings.
    • Dietary Intake and Biochemical Indicators and their Association with Wound Healing Process among Adult Burned Patients in the Gaza Strip

      Hammad, SM; Naser, IA; Taleb, MH; Abutair, AS (Enviro Research Publishers, 2019-02-25)
      Burn is a traumatic injury that causes immunological, endocrine, inflammatory, many metabolic responses and emotional stress which can affect dietary, micronutrients and antioxidants intake, which in turn have effects on recovery outcomes. To investigate the role of the nutrition and dietary intake on the progression of the different stages of the healing process among burned patients in Gaza strip. One hundred burned adult patients (36males and 64 females) were enrolled in this cross-sectional clinic-based study at Médecins Sans Frontières/ France clinics in Gaza Strip. Pretested interview questionnaires, Food Frequency Questionnaires, 24 hour dietary recall, anthropometric measures, and biochemical tests were used to assess dietary, health, and healing score among burned patients. This study reported positive association between Magnesium (χ2=8.700, p=0.013), Copper (χ2=60.916, p=<0.0001), and Vitamin C (χ2=91.684, p=<0.0001)) with healing score. The results reported that the protein and energy intake were significantly lower (< 0.001) than the recommendations for both components, which might explain the higher prevalence of moderate healing (65%) among the participants. The adequacy of micronutrients such as Magnesium, Copper, and Vitamin C might be associated with positive wound healing outcomes. Consumption of healthy food is very important for healing process among burned patients. There is a real need for planned and well-balanced meals for burned patients.
    • Long term outcomes and prognostics of visceral leishmaniasis in HIV infected patients with use of pentamidine as secondary prophylaxis based on CD4 level: a prospective cohort study in Ethiopia

      Diro, E; Edwards, T; Ritmeijer, K; Fikre, H; Abongomera, c; Kibret, A; Bardonneau, C; Soipei, P; Mutinda, B; Omollo, R; van Griensven, J; Zijlstra, EE; Wasunna, M; Alves, F; Alvar, J; Hailu, A; Alexander, N; Blesson, S (Public Library of Science, 2019-02-21)
      BACKGROUND: The long-term treatment outcome of visceral leishmaniasis (VL) patients with HIV co-infection is complicated by a high rate of relapse, especially when the CD4 count is low. Although use of secondary prophylaxis is recommended, it is not routinely practiced and data on its effectiveness and safety are limited. METHODS: A prospective cohort study was conducted in Northwest Ethiopia from August 2014 to August 2017 (NCT02011958). HIV-VL patients were followed for up to 12 months. Patients with CD4 cell counts below 200/μL at the end of VL treatment received pentamidine prophylaxis starting one month after parasitological cure, while those with CD4 count ≥200 cells/μL were followed without secondary prophylaxis. Compliance, safety and relapse-free survival, using Kaplan-Meier analysis methods to account for variable time at risk, were summarised. Risk factors for relapse or death were analysed. RESULTS: Fifty-four HIV patients were followed. The probability of relapse-free survival at one year was 50% (95% confidence interval [CI]: 35-63%): 53% (30-71%) in 22 patients with CD4 ≥200 cells/μL without pentamidine prophylaxis and 46% (26-63%) in 29 with CD4 <200 cells/μL who started pentamidine. Three patients with CD4 <200 cells/μL did not start pentamidine. Amongst those with CD4 ≥200 cells/μL, VL relapse was an independent risk factor for subsequent relapse or death (adjusted rate ratio: 5.42, 95% CI: 1.1-25.8). Except for one case of renal failure which was considered possibly related to pentamidine, there were no drug-related safety concerns. CONCLUSION: The relapse-free survival rate for VL patients with HIV was low. Relapse-free survival of patients with CD4 count <200cells/μL given pentamidine secondary prophylaxis appeared to be comparable to patients with a CD4 count ≥200 cells/μL not given prophylaxis. Patients with relapsed VL are at higher risk for subsequent relapse and should be considered a priority for secondary prophylaxis, irrespective of their CD4 count.
    • Severe post-kala-azar dermal leishmaniasis successfully treated with miltefosine in an Ethiopian HIV patient.

      Abongomera, C; Battaglioli, T; Adera, C; Ritmeijer, K (Elsevier, 2019-02-18)
      Post-kala-azar dermal leishmaniasis (PKDL) is a neglected tropical disease characterized by a dermatosis which often appears after successful treatment of visceral leishmaniasis caused by Leishmania donovani. PKDL treatment options are few and have severe limitations. In East- Africa, the standard treatment of PKDL is with daily painful potentially toxic sodium stibogluconate injections, administered for a prolonged duration of 30-60 days. In the Indian subcontinent, PKDL is mainly treated with miltefosine, a safer orally administered drug. However, in East-Africa, there is very limited experience in the use of miltefosine for treatment of severe PKDL, with only one published case report. Here we report a severe PKDL case in an Ethiopian HIV patient successfully treated with oral miltefosine (100 milligrams/day for 28 days). Miltefosine was efficacious, safe and well tolerated, suggesting that it can play an important role in the treatment of severe PKDL also in East-African patients. Further research is warranted.
    • "Even if she's really sick at home, she will pretend that everything is fine.": Delays in seeking care and treatment for advanced HIV disease in Kinshasa, Democratic Republic of Congo.

      Venables, E; Casteels, I; Manziasi Sumbi, E; Goemaere, E (Public Library of Science, 2019-02-13)
      HIV prevalence in the Democratic Republic of Congo (DRC) is estimated to be 1.2%, and access to HIV testing and treatment remains low across the country. Despite advances in treatment, HIV continues to be one of the main reasons for hospitalisation and death in low- and middle-income countries, including DRC, but the reasons why people delay seeking health-care when they are extremely sick remain little understood. People in Kinshasa, DRC, continue to present to health-care facilities in an advanced stage of HIV when they are close to death and needing intensive treatment.
    • Mortality in the first six months among HIV-positive and HIV-negative patients empirically treated for tuberculosis.

      Huerga, H; Ferlazzo, G; Wanjala, S; Bastard, M; Bevilacqua, P; Ardizzoni, E; Sitienei, J; Bonnet, M (BioMed Central, 2019-02-11)
      Empirical treatment of tuberculosis (TB) may be necessary in patients with negative or no Xpert MTB/RIF results. In a context with access to Xpert, we assessed mortality in the 6 months after the initial TB consultation among HIV-positive and HIV-negative patients who received empirical TB treatment or TB treatment based on bacteriological confirmation and we compared it with the mortality among those who did not receive TB treatment.
    • Diagnostics for filovirus detection: impact of recent outbreaks on the diagnostic landscape

      Emperador DM; Mazzola LT; Trainor BW; Chua A; Kelly-Cirino C (BMJ Publishing Group, 2019-02-07)
      Ebolaviruses and Marburg virus (MARV) both belong to the family Filoviridae and cause severe haemorrhagic fever in humans. Due to high mortality rates and potential for spread from rural to urban regions, they are listed on the WHO R&D blueprint of high-priority pathogens. Recent ebolavirus outbreaks in Western and Central Africa have highlighted the importance of diagnostic testing in epidemic preparedness for these pathogens and led to the rapid development of a number of commercially available benchtop and point-of-care nucleic acid amplification tests as well as serological assays and rapid diagnostic tests. Despite these advancements, challenges still remain. While products approved under emergency use licenses during outbreak periods may continue to be used post-outbreak, a lack of clarity and incentive surrounding the regulatory approval pathway during non-outbreak periods has deterred many manufacturers from seeking full approvals. Waning of funding and poor access to samples after the 2014–2016 outbreak also contributed to cessation of development once the outbreak was declared over. There is a need for tests with improved sensitivity and specificity, and assays that can use alternative sample types could reduce the need for invasive procedures and expensive equipment, making testing in field conditions more feasible. For MARV, availability of diagnostic tests is still limited, restricted to a single ELISA test and assay panels designed to differentiate between multiple pathogens. It may be helpful to extend the target product profile for ebolavirus diagnostics to include MARV, as the viruses have many overlapping characteristics.
    • Accelerating the Elimination of Viral Hepatitis: a Lancet Gastroenterology & Hepatology Commission.

      Cooke, GS; Andrieux-Meyer, I; Applegate, TL; Atun, R; Burry, JR; Cheinquer, H; Dusheiko, G; Feld, JJ; Gore, C; Griswold, MG; Hamid, S; Hellard, ME; Hou, J; Howell, J; Jia, J; Kravchenko, N; Lazarus, JV; Lemoine, M; Lesi, OA; Maistat, L; McMahon, BJ; Razavi, H; Roberts, TR; Simmons, B; Sonderup, MW; Spearman, WC; Taylor, BE; Thomas, DL; Waked, I; Ward, JW; Wiktor, SZ (Elsevier, 2019-02-01)
      Viral hepatitis is a major public health threat and a leading cause of death worldwide. Annual mortality from viral hepatitis is similar to that of other major infectious diseases such as HIV and tuberculosis. Highly effective prevention measures and treatments have made the global elimination of viral hepatitis a realistic goal, endorsed by all WHO member states. Ambitious targets call for a global reduction in hepatitis-related mortality of 65% and a 90% reduction in new infections by 2030. This Commission draws together a wide range of expertise to appraise the current global situation and to identify priorities globally, regionally, and nationally needed to accelerate progress. We identify 20 heavily burdened countries that account for over 75% of the global burden of viral hepatitis. Key recommendations include a greater focus on national progress towards elimination with support given, if necessary, through innovative financing measures to ensure elimination programmes are fully funded by 2020. In addition to further measures to improve access to vaccination and treatment, greater attention needs to be paid to access to affordable, high-quality diagnostics if testing is to reach the levels needed to achieve elimination goals. Simplified, decentralised models of care removing requirements for specialised prescribing will be required to reach those in need, together with sustained efforts to tackle stigma and discrimination. We identify key examples of the progress that has already been made in many countries throughout the world, demonstrating that sustained and coordinated efforts can be successful in achieving the WHO elimination goals.
    • Demonstration of the Diagnostic Agreement of Capillary and Venous Blood Samples, Using Hepatitis-C Virus SD Bioline© Rapid Test: A Clinic-based Study

      Sun, C; Iwamoto, M; Calzia, A; Sreng, B; Yann, S; Pin, S; Lastrucci, C; Kimchamroeun, S; Dimanche, C; Dousset, JP; Le Paih, M; Balkan, S; Marquardt, T; Carnimeo, V; Lissouba, P; Maman, D; Loarec, A (Elsevier, 2019-02)
      Simplifying hepatitis C virus (HCV) screening is a key step in achieving the elimination of HCV as a global public health threat by 2030.
    • Countries are out of step with international recommendations for tuberculosis testing, treatment, and care: Findings from a 29-country survey of policy adoption and implementation

      Saran, K; Masini, T; Chikwanha, I; Paton, G; Scourse, R; Kahn, P; Sahu, S; Perrin, C; Ditiu, L; Lynch, S (bioRxiv, 2019-02-01)
      Background: Tuberculosis (TB) poses a global health crisis requiring robust international and country-level action. Adopting and implementing TB policies from the World Health Organization (WHO) is essential to meeting global targets for reducing TB burden. However, many high TB burden countries lag in implementing WHO recommendations. Assessing the progress of implementation at national level can identify key gaps that must be addressed to expand and improve TB care. Methods: In 2016/2017, Médecins Sans Frontières and the Stop TB Partnership conducted a survey on adoption and implementation of 47 WHO TB policies in the national TB programs of 29 countries. Here we analyze a subset of 23 key policies in diagnosis, models of care, treatment, prevention, and drug regulation to provide a snapshot of national TB policy adoption and implementation. We examine progress since an analogous 2015 survey of 23 of the same countries. Results: At the time of the survey, many countries had not yet aligned their national guidelines with all WHO recommendations, although some progress was seen since 2015. For diagnosis, about half of surveyed countries had adopted the WHO-recommended initial rapid test (Xpert MTB/RIF). A majority of countries had adopted decentralized models of care, although one-third of them still required hospitalization for drug-resistant (DR-)TB. Recommended use of the newer drugs bedaquiline (registered in only 6 high-burden TB countries) and delamanid (not registered in any high-burden country) was adopted by 23 and 18 countries, respectively, but short-course (9-month) and newer pediatric regimens by only 13 and 14 countries, respectively. Guidelines in all countries included preventive treatment of latent TB infection for child TB contacts and people living with HIV/AIDS, but only four extended this to adult contacts. Conclusion: To reach global TB targets, greater political will is needed to rapidly adopt and implement internationally recognized care guidelines.
    • Post-traumatic osteomyelitis in Middle East war-wounded civilians: resistance to first-line antibiotics in selected bacteria over the decade 2006-2016.

      Fily, F; Ronat, JB; Malou, N; Kanapathipillai, R; Seguin, C; Hussein, N; Fakhri, RM; Langendorf, C (BioMed Central, 2019-01-31)
      War-wounded civilians in Middle East countries are at risk of post-traumatic osteomyelitis (PTO). We aimed to describe and compare the bacterial etiology and proportion of first-line antibiotics resistant bacteria (FLAR) among PTO cases in civilians from Syria, Iraq and Yemen admitted to the reconstructive surgical program of Médecins Sans Frontières (MSF) in Amman, Jordan, and to identify risk factors for developing PTO with FLAR bacteria.
    • A Randomized Trial of AmBisome Monotherapy and AmBisome and Miltefosine Combination to Treat Visceral leishmaniasis in HIV Co-infected Patients in Ethiopia

      Diro, E; Blesson, S; Edwards, T; Ritmeijer, K; Fikre, H; Admassu, H; Kibret, A; Ellis, SJ; Bardonneau, C; Zijlstra, EE; Soipei, P; Mutinda, B; Omollo, R; Kimutai, R; Omwalo, G; Wasunna, M; Tadesse, F; Alves, F; Strub-Wourgaft, N; Hailu, A; Alexander, N; Alvar, J (Public Library of Science, 2019-01-17)
      Visceral leishmaniasis (VL) in human immunodeficiency virus (HIV) co-infected patients requires special case management. AmBisome monotherapy at 40 mg/kg is recommended by the World Health Organization. The objective of the study was to assess if a combination of a lower dose of AmBisome with miltefosine would show acceptable efficacy at the end of treatment.
    • 'I saw it as a second chance': A qualitative exploration of experiences of treatment failure and regimen change among people living with HIV on second- and third-line antiretroviral therapy in Kenya, Malawi and Mozambique

      Burns, R; Borges, J; Blasco, P; Vandenbulcke, A; Mukui, I; Magalasi, D; Molfino, L; Manuel, R; Schramm, B; Wringe, A (Taylor & Francis, 2019-01-11)
      Increasing numbers of people living with HIV (PLHIV) in sub-Saharan Africa are experiencing failure of first-line antiretroviral therapy and transitioning onto second-line regimens. However, there is a dearth of research on their treatment experiences. We conducted in-depth interviews with 43 PLHIV on second- or third-line antiretroviral therapy and 15 HIV health workers in Kenya, Malawi and Mozambique to explore patients' and health workers' perspectives on these transitions. Interviews were audio-recorded, transcribed and translated into English. Data were coded inductively and analysed thematically. In all settings, experiences of treatment failure and associated episodes of ill-health disrupted daily social and economic activities, and recalled earlier fears of dying from HIV. Transitioning onto more effective regimens often represented a second (or third) chance to (re-)engage with HIV care, with patients prioritising their health over other aspects of their lives. However, many patients struggled to maintain these transformations, particularly when faced with persistent social challenges to pill-taking, alongside the burden of more complex regimens and an inability to mobilise sufficient resources to accommodate change. Efforts to identify treatment failure and support regimen change must account for these patients' unique illness and treatment histories, and interventions should incorporate tailored counselling and social and economic support.

    • Reducing Lead and Silica Dust Exposures in Small-Scale Mining in Northern Nigeria.

      Gottesfeld, P; Tirima, S; Anka, SM; Fotso, A; Nota, MM (2019-01-07)
      An ongoing health crisis across a large area of Northern Nigeria has resulted in hundreds of deaths and thousands of cases of lead poisoning from artisanal small-scale gold mining. Occupational Knowledge International (OK International) and Doctors Without Borders/Médecins Sans Frontières (MSF) have formed a partnership to conduct a pilot project to introduce safer mining practices in selected communities. The primary objective was to reduce lead exposures among artisanal small-scale miners and minimize take home exposures by reducing dust contamination on clothing and body surfaces.
