Over 3 million children died from AMR-related infections in 2022, major study shows

(Press-News.org) A landmark study presented today at ESCMID Global 2025 has revealed that over 3 million children worldwide lost their lives in 2022 due to antimicrobial resistance (AMR)-related infections.1

The study underscores the urgent need for both regional and global strategies to control paediatric AMR, particularly in high-burden areas such as South-East Asia and Africa. AMR poses a critical threat to children, who are highly vulnerable to infections.2 Access to new antibiotic formulations is often much more limited for children because of product development delays.

The study data found that in 2022 alone, more than 752,000 children in Southeast Asia and 659,000 children in Africa died of AMR-associated complications. Many of these deaths were linked to the use of Watch antibiotics (drugs with a high risk of resistance) and Reserve antibiotics (last-resort treatments for severe, multidrug-resistant infections).1,3

Watch and Reserve antibiotics are not intended for first-line treatment and their use should be limited only for those who need them to preserve their effectiveness and reduce the development of resistance. In contrast, Access antibiotics are those that are more widely available and used to treat common infections due to their lower potential for increasing resistance.

Between 2019 and 2021, the use of Watch antibiotics increased by 160% in Southeast Asia and 126% in Africa. During the same period, the use of Reserve antibiotics rose by 45% in Southeast Asia and 125% in Africa.

Globally, of the more than 3 million children’s deaths, 2 million were associated with the use of Watch and Reserve antibiotics.

“While the rise in use of Watch and Reserve antibiotics may be necessary in response to the concurrent rise in drug-resistant infections, the sharp rise in use of these drugs presents several serious long-term risks”, commented Professor Joseph Harwell, study co-author. “Their increased use, especially without careful oversight, elevates the risk of resistance and limits future treatment options. If bacteria develop resistance to these antibiotics, there will be few, if any, alternatives for treating multidrug-resistance infections.” 

Several factors contribute to the severity of AMR in low- and middle-income countries, including overcrowded hospitals, poor sanitation, and weak infection prevention measures that facilitate the spread of resistant pathogens within healthcare settings and communities. Due to a lack of diagnostic tools and concerns over misdiagnosis, overuse and misuse of antibiotics are also widespread in these regions. Additionally, many low- and middle-income countries lack effective national surveillance and antimicrobial stewardship programmes, making it difficult to track resistance trends and establish effective treatment protocols.

“Rising resistance to Watch and Reserve antibiotics will ultimately lead to higher treatment failure,” said Professor Harwell. “Mortality rates, which are already alarmingly high, will continue to rise significantly, particularly in low- and middle-income countries where access to alternative treatments and advanced medical interventions may be limited.”

Professor Harwell furthered, “Addressing this issue requires urgent and coordinated action at both the regional and global levels. Global and national surveillance on AMR must adopt a ‘One Health’ approach, with cost-effective systems that can inform treatment guidelines and measure the impact of control interventions.”

“On a regional level, we call on policymakers to mandate hospital-based antimicrobial stewardship programmes in all paediatric healthcare facilities. Improved age classifications in surveillance data will also enhance our understanding of important differences in resistance rates across the age categories, as well as paediatric-specific resistance mechanisms. Additionally, we urge the implementation of national guidelines to ensure routine surveillance informs antibiotic use,” concluded Professor Harwell.

About the study data

The study incorporated data from the Pfizer ATLAS programme provided through the Vivli platform, along with WHO’s GLASS on antibiotic use, the World Bank data on demographics, and IHME mortality data.

About Access, Watch and Reserve antibiotics4

Access antibiotics are antibiotics with a narrow spectrum of activity, generally with less side-effects, a lower potential for the selection of antimicrobial resistance and of lower cost. They are recommended for the empiric treatment of most common infections and should be widely available. Watch antibiotics generally have a higher potential for the selection of antimicrobial resistance and are more commonly used in sicker patients in the hospital facility setting. Their use should be carefully monitored to avoid overuse. Reserve antibiotics are last-resort antibiotics that should only be used to treat severe infections caused by multidrug-resistant pathogens.

Breakthrough study identifies promising biomarker for early sepsis detection in neonates, children, and pregnant women

2025-04-11
Breakthrough study identifies promising biomarker for early sepsis detection in neonates, children, and pregnant women A pioneering study presented today at ESCMID Global 2025 has uncovered the potential of interleukin-6 (IL-6) as a powerful diagnostic biomarker for the early detection of sepsis in high-risk patient groups, including neonates, children and pregnant women. This study is the first to evaluate IL-6’s diagnostic performance in a real-world cohort across all three populations.1 Sepsis, a life-threatening condition resulting from the immune system’s overreaction to infection, remains a leading global cause of mortality, accounting ...

3-year study of tirzepatide shows that most patients only gain 5% or less from their lowest or ‘nadir’ weight

2025-04-11
New research to be presented at this year’s European Congress on Obesity (ECO 2025, Malaga, Spain, 11-14 May) shows that around two thirds of participants of the SURMOUNT-1 trial had only regained 5% or less of their so-called nadir (or lowest weight) three years after beginning treatment with tirzepatide. The study is by Professor Louis Aronne, Comprehensive Weight Control Center, Division of Endocrinology, Diabetes, and Metabolism, Weill Cornell Medicine, New York, NY, USA, and co-authors from Eli Lilly and Company, Indianapolis, IN, USA, which funded the study. Obesity management is a long-term journey during which fluctuations ...

Tirzepatide can produce clinically meaningful weight loss for at least 3 years in adults with overweight or obesity who don’t have diabetes

2025-04-11
