Antibiotic resistance claimed over a million lives in three decades, 39 million could die by 2050: Study

An improved access to health care and antibiotics could save a total of 92 million lives between 2025 and 2050, the authors estimated. At least 60% of the 29.9 lakh sepsis deaths in India in 2019 were caused by bacterial infection, according to the study.

At least 60% of the 29.9 lakh sepsis deaths in India in 2019 were caused by bacterial infection.

Over a million people around the world died due to antibiotic resistance between 1990 and 2021, and to make the matters worse, more than 39 million could die from antibiotic-resistant infections by 2050, according to a global analysis published in The Lancet journal.

At least 60% of the 29.9 lakh sepsis deaths in India in 2019 were caused by bacterial infection which indicates that overuse or wrongful use of antibiotics can prove fatal.

Sepsis deaths occur when one’s immune system has a dangerous reaction to a bacterial infection and without treatment it can lead to organ failure.

Future deaths from antibiotic resistance are estimated to be highest in South Asia — including India, Pakistan, and Bangladesh — where a total of 11.8 million deaths directly due to it are predicted between 2025 and 2050, a collaboration of researchers forming the Global Research on Antimicrobial Resistance GRAM) Project said.

The researchers said deaths due to antibiotic resistance will also be high in other parts of southern and eastern Asia and sub-Saharan Africa.

The authors said trends between 1990 and 2021 suggested that among people aged 70 years and above, deaths caused by antibiotic resistance increased by more than 80%, and will continue to affect older people more in the years to come.

Deaths due to antibiotic resistance among children aged under five years fell by more than 50% during the same period.

“The fall in deaths from sepsis (a bloodstream infection) and antibiotic resistance among young children over the past three decades is an incredible achievement. However, these findings show that while infections have become less common in young children, they have become harder to treat when they occur,” said Kevin Ikuta, one of the collaborators on the GRAMProject and an affiliate professor at the Institute of Health Metrics (IHME), University of Washington, US.

“Further, the threat to older people from antimicrobial resistance will only increase as populations age. Now is the time to act to protect people around the world from the threat posed by antimicrobial resistance,” Ikuta said.

An improved access to health care and antibiotics could save a total of 92 million lives between 2025 and 2050, the authors estimated. The study is the first global analysis of antimicrobial resistance trends over time, they said.

An increasing resistance to antibiotics — one of the “cornerstones of modern healthcare” — is a major cause for concern and the findings highlighted the significance of the global health threat, according to author Mohsen Naghavi from the IHME.

“Understanding how trends in antimicrobial resistance deaths have changed over time, and how they are likely to shift in the future, is vital to make informed decisions to help save lives,” Naghavi said.

The analysis was based on data from 520 million people of all ages in 204 countries and territories, taken from a wide range of sources, including hospital and death records, and antibiotic use information.

The estimates produced are related to 22 disease-causing microbes (pathogens), 84 pathogen-drug combinations, and 11 infectious symptoms such as bloodstream infections, the authors said.

In 2019, deaths related to antibiotic resistance were higher than those from HIV/AIDS or Malaria, leading directly to 1.2 million deaths and playing a role in a further nearly five million deaths, according to the first study by the GRAM Project, published in 2022.
