Provision of antiretroviral treatment in conflict settings: the experience of Médecins Sans Frontières

Introduction  

Many countries ravaged by conflict have substantial morbidity and mortality attributed to HIV/AIDS yet HIV treatment is uncommonly available. Universal access to HIV care cannot be achieved unless the needs of populations in conflict-affected areas are addressed.     

Feasibility of Xpert Ebola Assay in Médecins Sans Frontières Ebola Program,Guinea

Rapid diagnostic methods are essential in control of Ebola outbreaks and lead to timely isolation of cases and improved epidemiologic surveillance. Diagnosis during Ebola outbreaks in West Africa has relied on PCR performed in laboratories outside this region. Because time between sampling and PCR results can be considerable, we assessed the feasibility and added value of using the Xpert Ebola Assay in an Ebola control program in Guinea. A total of 218 samples were collected during diagnosis, treatment, and convalescence of patients. Median time for obtaining results was reduced from 334 min to 165 min. Twenty-six samples were positive for Ebola virus. Xpert cycle thresholds were consistently lower, and 8 (31%) samples were negative by routine PCR. Several logistic and safety issues were identified. We suggest that implementation of the Xpert Ebola Assay under programmatic conditions is feasible and represents a major advance in diagnosis of Ebola virus disease without apparent loss of assay sensitivity.     

Why Médecins Sans Frontières (MSF) provides safe abortion care and what that involves

MSF responds to needs for the termination of pregnancy, including on request (TPR); it is part of the organization’s work aimed at reducing maternal mortality and suffering; and preventing unsafe abortions in the countries where we work. Following the publication of “Why don’t humanitarian organizations provide safe abortion care?” we offer an insight into MSF’s experience over the past few years. The article looks at the legal concerns and proposes that the importance of addressing maternal mortality should replace them and the operational set-up and action organized in a way that mitigates risks. MSF took a policy decision on safe abortion care in 2004; the fact that care did not expand rapidly to relevant MSF projects came as a surprise, reflecting the important weight social norms around abortion have everywhere. The need to engage in an open dialogue with staff, relevant medical actors and at community level became more obvious. Finally the article looks some key lessons that have emerged for the organization as part of the effort to prevent ill health, maternal death and suffering caused by unwanted pregnancy and unsafe abortion.     

Effectiveness of melarsoprol and eflornithine as first-line regimens for gambiense sleeping sickness in nine Médecins Sans Frontières programmes

This paper describes the effectiveness of first-line regimens for stage 2 human African trypanosomiasis (HAT) due to Trypanosoma brucei gambiense infection in nine Médecins Sans Frontières HAT treatment programmes in Angola, Republic of Congo, Sudan and Uganda. Regimens included eflornithine and standard- and short-course melarsoprol. Outcomes for 10461 na?ve stage 2 patients fitting a standardised case definition and allocated to one of the above regimens were analysed by intention-to-treat analysis. Effectiveness was quantified by the case fatality rate (CFR) during treatment, the proportion probably and definitely cured and the Kaplan-Meier probability of relapse-free survival at 12 months and 24 months post admission. The CFR was similar for the standard- and short-course melarsoprol regimens (4.9% and 4.2%, respectively). The CFR for eflornithine was 1.2%. Kaplan-Meier survival probabilities varied from 71.4-91.8% at 1 year and 56.5-87.9% at 2 years for standard-course melarsoprol, to 73.0-91.1% at 1 year for short-course melarsoprol, and 79.9-97.4% at 1 year and 68.6-93.7% at 2 years for eflornithine. With the exception of one programme, survival at 12 months was >90% for eflornithine, whilst for melarsoprol it was <90% except in two sites. Eflornithine is recommended where feasible, especially in areas with low melarsoprol effectiveness.     

Royal Society of Tropical Medicine and Hygiene joint meeting with Médecins Sans Frontières at Manson House, London, 20 March 2003: field research in humanitarian medical programmes. Médecins Sans Frontières interventions against kala-azar in the Sudan, 1989-2003

Since 1989, Médecins Sans Frontières (MSF) has provided medical humanitarian assistance during outbreaks of visceral leishmaniasis (VL; kala-azar) in Sudan. First, in western Upper Nile in southern Sudan, where a VL epidemic occurred after the resumption of the civil war in Sudan in 1983, with an estimated 100,000 deaths. Later, MSF started interventions in eastern Upper Nile and Gedaref State. In these two endemic regions VL incidence has risen markedly since 2001, which could be the start of a new epidemic cycle. Outbreaks of VL in Sudan remain unpredictable, and access to affected populations in war-torn southern Sudan is often hampered by insecurity. Therefore, MSF takes a flexible approach, establishing treatment centres where patients can be accessed. From 1989 to 2002, MSF treated >51,000 VL cases in Sudan. Despite very basic field conditions, high cure rates of 95% are being achieved. Lack of diagnostics is a major obstacle to treatment, especially during epidemic situations. Therefore, development of simple and rapid technologies is required, allowing reliable diagnosis under field conditions. For treatment of VL there is a limited choice of effective, affordable drugs. There are strong indications of an emerging resistance to antimonials in Malakal. Introduction of combination therapies is urgently needed to prevent the further emergence and spread of resistance to antimonials, which are still the mainstay of VL treatment in eastern Africa. Experience with combination therapy with sodium stibogluconate (SSG) and paromomycin is promising, and combinations of SSg with liposomal amphotericin B and miltefosine are currently being explored.     

Brief mental health interventions in conflict and emergency settings: an overview of four Médecins Sans Frontières – France programs

Introduction

Mental health problems, particularly anxiety and mood disorders, are prevalent in the setting of humanitarian emergencies, both natural and man-made disasters. Evidence regarding best strategies for therapeutic interventions is sparse. Médecins Sans Frontières has been providing mental health services during emergencies for over two decades, and here we compare data from four programs.

Program Overview

In China, 564 patients were followed for an average of 7 sessions after a major earthquake. The most common diagnoses were PTSD and other anxiety disorders. Between program entry and exit, the median global assessment of functioning increased from 65 to 80. At program entry, 58% were considered moderately, markedly or severely ill; a proportion which fell to 14% at program exit. In Colombia in the setting of chronic violence, 2411 patients were followed for a median of two sessions. Anxiety disorders and major depression were the most common diagnoses, and 76% of patients were moderately or severely ill at program entry. 91% had symptomatic improvement at program exit. In Gaza, 1357 patients were followed for a median of 9 sessions; a majority was under age 15. PTSD and other anxiety disorders were the most common diagnoses, and 91% were moderately or severely ill at entry. 89% had improved symptoms at program exit. In the West Bank, the 1478 patients had similar characteristics to those enrolled in Gaza. 88% were moderately or severely ill at entry; 88% had improved at exit.

Discussion and evaluation

It was feasible to implement brief yet effective mental health interventions in a wide variety of humanitarian contexts – post-natural disaster, during acute violent conflict and during chronic violent conflict. The most common diagnoses were PTSD, other anxiety disorders and mood disorders. The use of local specially-trained counselors who were focused on coping skills and improving functionality over a brief time period, likely contributed to the symptomatic improvement seen in a large majority of patients across the four sites.

Conclusions

Mental health is an essential part of a health care response to humanitarian emergencies. In a variety of settings, we show the positive results of brief interventions. Further research is needed to improve and evaluate mental health interventions in crises.

     

Médecins Sans Frontières' Clinical Guidance mobile application: analysis of a new electronic health tool

Many health care workers lack access to clinical support tools in rural and resource-limited settings. To address this gap, the Médecins Sans Frontières (MSF) Clinical Guidelines manual was converted into a static mobile health reference application (app) entitled MSF Guidance. The app''s utility and growth was examined, and within 6 months of its launch 150 countries had downloaded the app, with demonstrated retention among new and existing users. With over 3500 downloads and 36 000 sessions amounting to 250 000 screen views, MSF Guidance is a new mobile health platform with widely demonstrated utility, including potential use as an epidemiological tool, where clinical conditions investigated by app users were found to correlate with geographical outbreaks. These findings show that mobile apps can be used to disseminate health information effectively.     

Causes of pediatric mortality and case-fatality rates in eight Médecins Sans Frontières-supported hospitals in Africa

Setting:

Eight pediatric hospital in-patient wards in remote, rural and/or insecure areas in Africa.

Objectives:

To describe, in children aged <5 years, 1) overall and individual mortality rates, 2) the 10 most common causes of mortality, and 3) their case-fatality rates.

Design:

Retrospective analysis of routinely collected standardized program data for 2010.

Results:

During 2010, 21 357 children aged <5 years were admitted and 1520 died, resulting in an overall in-patient mortality rate among under-fives of 7%. This remained the same after considering the three most common causes of mortality per hospital. One hospital with a neonatal unit showed a mortality rate of 14%. Of the 10 most common causes of mortality in the eight hospitals, severe malaria, acute lower respiratory tract infection and neonatal infection counted for about 77% of total deaths. Ranking the 10 most common causes of mortality according to case-fatality rates, septicemia, meningitis, low birth weight with pathology, neonatal infection and neonatal asphyxia were the most common (case-fatality rates 15–40%).

Conclusion:

Despite widely different contexts, mortality rates for pediatric in-patients were consistently under 10%. To further reduce mortality, emphasis should be placed on treating sepsis and introducing implementable and/or adapted care packages for neonatal-related pathologies.     

The Médicins sans Frontières HIV/AIDS programme in Ukraine

In 1999, Médicins sans Frontières started an HIV/AIDS programme in Ukraine, a country with an estimated 410,000 people with HIV (1.4% prevalence), including 53,000 in urgent need of antiretroviral therapy. Between 1999 and 2004, a comprehensive HIV/AIDS programme was implemented in close collaboration with the Ministry of Health in AIDS centres in Odessa, Mikolaev and Simferopol. Initial activities included prevention and treatment advocacy campaigns, which were later followed by prevention of mother-to-child transmission, treatment of opportunistic infections, antiretroviral therapy for infants and adults and palliative care. This programme has served as a model and has led to meaningful improvements in HIV/AIDS care in Ukraine. It demonstrates that adequate care for patients with HIV or AIDS is possible in countries like Ukraine.
