MSF Scientific Days Asia 2024

Viral hepatitis is a major cause of disease and death globally. To mark World Hepatitis Day (July 28th) we present a selection of recent MSF research exploring how to effectively deploy powerful medical tools that could turn the tide on hepatitis C and E—but now reach only a tiny fraction of people who desperately need them, especially in low-resource and emergency settings. For hepatitis C, where groundbreaking new antiviral drugs can cure nearly all patients, MSF is piloting simplified, community-based models of care that offer rapid screening, diagnosis, and treatment under one roof. Some programs focus on the complex needs of highly vulnerable, hard-to-reach populations, such as people co-infected with HIV or TB or who inject drugs. Turning to prevention, an ongoing vaccination campaign against hepatitis E in an outbreak setting is showing early signs of short-term protection. Final results from this South Sudanese refugee camp, where poor sanitation and water quality regularly lead to outbreaks, should help plug a key evidence gap that—along with other barriers discussed in a commentary article—impedes widespread uptake of the vaccine.

Many settings with a high burden of drug-resistant tuberculosis (DR-TB) lack access to advanced diagnostics and to groundbreaking new treatments. The Collection linked below spotlights work by MSF and collaborators to analyze barriers, identify gaps, and accelerate the roll-out of these tools to people whose lives hang in the balance. Several reports examine price, regulatory, and patent obstacles that persist despite considerable public investment into developing many of these tools. Other authors examine critical remaining weaknesses in care pathways—especially in screening and diagnosis, and particularly in children. Several studies describe new strategies that could be part of the solution, from a pilot program in Tajikisttan that trains family caregivers to treat children with DR-TB at home, to a person-centered care model adapted to a conflict zone in Afghanistan. Lastly, initial findings demonstrate that pregnant women—another vulnerable population—can be effectively treated for DR- and multidrug-resistant TB, improving maternal outcomes without harming neonates.
