RESUMO
Access to hepatitis C virus (HCV) testing and treatment is limited in Myanmar. We assessed an integrated HIV and viral hepatitis testing and HCV treatment strategy. Sofosbuvir/velpatasvir (SOF/VEL) ± weight-based ribavirin for 12 weeks was provided at three treatment sites in Myanmar and sustained virologic response (SVR) assessed at 12 weeks after treatment. Participants co-infected with HBV were treated concurrently with tenofovir. Cost estimates in 2018 USD were made at Yangon and Mandalay using standard micro-costing methods. 803 participants initiated SOF/VEL; 4.8% were lost to follow-up. SVR was achieved in 680/803 (84.6%) by intention-to-treat analysis. SVR amongst people who inject drugs (PWID) was 79.7% (381/497), but 92.5% among PWID on opioid substitution therapy (OST) (74/80), and 97.4% among non-PWID (298/306). Utilizing data from 492 participants, of whom 93% achieved SVR, the estimated average cost of treatment per patient initiated was $1030 (of which 54% were medication costs), with a production cost per successful outcome (SVR) of $1109 and real-world estimate of $1250. High SVR rates were achieved for non-PWID and PWID on OST. However, the estimated average cost of the intervention (under the assumption of no genotype testing and reduced real-world effectiveness) of $1250/patient is unaffordable for a national elimination strategy. Reductions in the cost of antivirals and linkage to social and behavioural health services including substance use disorder treatment to increase retention and adherence to treatment are critical to HCV elimination in this population.

BACKGROUND: Globally, policy-makers face challenges to using evidence in health decision-making, particularly lack of interaction between research and policy. Knowledge-brokering mechanisms can fill research-policy gaps and facilitate evidence-informed policy-making. In Myanmar, the need to promote evidence-informed policy is significant, and thus a mechanism was set up for this purpose. This paper discusses lessons learned from the development of the Knowledge Broker Group-Myanmar (KBG-M), supported by the Johns Hopkins Bloomberg School of Public Health's Applied Mental Health Research Group (JHU) and Community Partners International (CPI). METHODS: Sixteen stakeholders were interviewed to explore challenges in formulating evidence-informed policy. Two workshops were held: the first to further understand the needs of policy-makers and discuss knowledge-brokering approaches, and the second to co-create the KBG-M structure and process. The KBG-M was then envisioned as an independent body, with former officials of the Ministry of Health and Sports (MoHS) and representatives from the nongovernmental sector actively engaging in the health sector, with an official collaboration with the MoHS. RESULTS: A development task force that served as an advisory committee was established. Then, steps were taken to establish the KBG-M and obtain official recognition from the MoHS. Finally, when the technical agreement with the MoHS was nearly complete, the process stopped because of the military coup on 1 February 2021, and is now on hold indefinitely. CONCLUSIONS: Learning from this process may be helpful for future or current knowledge-brokering efforts, particularly in fragile, conflict-affected settings. Experienced and committed advisory committee members enhanced stakeholder relationships. Responsive coordination mechanisms allowed for adjustments to a changing bureaucratic landscape. Coordination with similar initiatives avoided overlap and identified areas needing technical support. Recommendations to continue the work of the KBG-M itself or similar platforms include the following: increase resilience to contextual changes by ensuring diverse partnerships, maintain advisory committee members experienced and influential in the policy-making process, ensure strong organizational and funding support for effective functioning and sustainability, have budget and timeline flexibility to allow sufficient time and resources for establishment, organize ongoing needs assessments to identify areas needing technical support and to develop responsive corrective approaches, and conduct information sharing and collaboration between stakeholders to ensure alignment.

BACKGROUND: Greater Mekong Subregion countries are committed to eliminating Plasmodium falciparum malaria by 2025. Current elimination interventions target infections at parasite densities that can be detected by standard microscopy or rapid diagnostic tests (RDTs). More sensitive detection methods have been developed to detect lower density "asymptomatic" infections that may represent an important transmission reservoir. These ultrasensitive polymerase chain reaction (usPCR) tests have been used to identify target populations for mass drug administration (MDA). To date, malaria usPCR tests have used either venous or capillary blood sampling, which entails complex sample collection, processing and shipping requirements. An ultrasensitive method performed on standard dried blood spots (DBS) would greatly facilitate the molecular surveillance studies needed for targeting elimination interventions. METHODS: A highly sensitive method for detecting Plasmodium falciparum and P. vivax 18S ribosomal RNA from DBS was developed by empirically optimizing nucleic acid extraction conditions. The limit of detection (LoD) was determined using spiked DBS samples that were dried and stored under simulated field conditions. Further, to assess its utility for routine molecular surveillance, two cross-sectional surveys were performed in Myanmar during the wet and dry seasons. RESULTS: The lower LoD of the DBS-based ultrasensitive assay was 20 parasites/mL for DBS collected on Whatman 3MM filter paper and 23 parasites/mL for Whatman 903 Protein Saver cards-equivalent to 1 parasite per 50 µL DBS. This is about 5000-fold more sensitive than standard RDTs and similar to the LoD of ≤16-22 parasites/mL reported for other ultrasensitive methods based on whole blood. In two cross-sectional surveys in Myanmar, nearly identical prevalence estimates were obtained from contemporaneous DBS samples and capillary blood samples collected during the wet and dry season. CONCLUSIONS: The DBS-based ultrasensitive method described in this study shows equal sensitivity as previously described methods based on whole blood, both in its limit of detection and prevalence estimates in two field surveys. The reduced cost and complexity of this method will allow for the scale-up of surveillance studies to target MDA and other malaria elimination interventions, and help lead to a better understanding of the epidemiology of low-density malaria infections.

BACKGROUND: Highly sensitive, scalable diagnostic methods are needed to guide malaria elimination interventions. While traditional microscopy and rapid diagnostic tests (RDTs) are suitable for the diagnosis of symptomatic malaria infection, more sensitive tests are needed to screen for low-density, asymptomatic infections that are targeted by interventions aiming to eliminate the entire reservoir of malaria infection in humans. METHODS: A reverse transcription polymerase chain reaction (RT- PCR) was developed for multiplexed detection of the 18S ribosomal RNA gene and ribosomal RNA of Plasmodium falciparum and Plasmodium vivax. Simulated field samples stored for 14 days with sample preservation buffer were used to assess the analytical sensitivity and specificity. Additionally, 1750 field samples from Southeastern Myanmar were tested both by RDT and ultrasensitive RT-PCR. RESULTS: Limits of detection (LoD) were determined under simulated field conditions. When 0.3 mL blood samples were stored for 14 days at 28 °C and 80% humidity, the LoD was less than 16 parasites/mL for P. falciparum and 19.7 copies/µL for P. vivax (using a plasmid surrogate), about 10,000-fold lower than RDTs. Of the 1739 samples successfully evaluated by both ultrasensitive RT-PCR and RDT, only two were RDT positive while 24 were positive for P. falciparum, 108 were positive for P. vivax, and 127 were positive for either P. vivax and/or P. falciparum using ultrasensitive RT-PCR. CONCLUSIONS: This ultrasensitive RT-PCR method is a robust, field-tested screening method that is vastly more sensitive than RDTs. Further optimization may result in a truly scalable tool suitable for widespread surveillance of low-level asymptomatic P. falciparum and P. vivax parasitaemia.

This case study analyses a health project that focused on peacebuilding in addition to service provision, and the impacts of this dual focus in contested territories of Southeast Myanmar. The Swiss-funded Primary Health Care Project provided equal funds to both 'sides' in a decades-long conflict, and brought people together in ways designed to build trust. The case study demonstrates that health can play a valuable role in peace formation, if relationships are engineered in a politically sensitive way, at the right time. Whereas much of the literature on 'health as a bridge to peace' focuses on the apolitical in health, here the explicitly political approach and the deliberate adoption of neutrality as a tool for engaging with different parties were what enabled health to contribute to peace, using a political window of opportunity created by ceasefires and the beginnings of democratic transition in Myanmar. We argue that this approach was essential for health to contribute to bottom-up processes of peace formation-though the scope of the gains is necessarily limited. Crises like the COVID-19 pandemic and military coup in Myanmar can undermine the resilience and limit the impacts of such endeavours, yet there is reason to be hopeful about the small but significant contributions that can be made to peace through politically sensitive health projects.

BACKGROUND: In Myanmar, over five million people are infected with hepatitis B virus (HBV) and hepatitis C virus (HCV). Hepatitis has been a recent focus with the development of a National Strategic Plan on Hepatitis and plans to subsidize HCV treatment. METHODS: During a two-day national liver disease symposium covering HCV, HBV, hepatocellular (HCC), and end-stage liver disease (ESLD), physician surveys were administered using the automated response system (ARS) to assess physician knowledge, perceptions of barriers to screening and treatment, and proposed solutions. Multivariate logistic regression was used to estimate odds ratio (OR) relating demography and practice factors with higher provider knowledge and improvement. RESULTS: One hundred two physicians attending from various specialty areas (31.0% specializing in gastroenterology/hepatology and/or infectious disease) were of mixed gender (46.8% male), were younger than or equal to 40 years old (51.1% 20 to 40 years), had less experience (61.6% with ≤10 years of medical practice), were from the metropolitan area of Yangon (72.1%), and saw <10 liver disease patients per week (74.3%). The majority of physicians were not comfortable with treating or managing patients with liver disease. The post-test scores demonstrated an improvement in liver disease knowledge (9.0% ± 27.0) compared to the baseline pre-test scores; no variables were associated with significant improvement in hepatitis knowledge. Physicians identified the cost of diagnostic blood tests and treatment as the most significant barrier to treatment. Top solutions proposed were universal screening policies (46%), removal of financial barriers for treatment (29%), patient education (14%) and provider education (11%). CONCLUSIONS: Physician knowledge improved after this symposium, and many other needs were revealed by the physician input on barriers to care and their solutions. These survey results are important in guiding the next steps to improve liver disease management and future medical education efforts in Myanmar.
