Antibiotic-resistant superbugs killed 1.2 mn in 2019: study

PARIS, Jan 20, 2022 (BSS/AFP) - Superbug infections killed 1.2 million
people in 2019, according to a study published Thursday, which authors
described as the most comprehensive assessment of the impact of antimicrobial
resistance to date.

   The death toll means infections by bacteria resistant to antibiotics are
directly responsible for more deaths than HIV/AIDS or malaria.

   The report, published in the Lancet, also found antimicrobial resistance
played a role in up to 3.68 million other deaths.

   "These new data reveal the true scale of antimicrobial resistance
worldwide, and are a clear signal that we must act now to combat the threat,"
said study co-author Chris Murray of the University of Washington.

   While previous estimates said superbugs could kill 10 million people per
year by 2050, this study shows that milestone could be reached much sooner,
he added.

   "We need to leverage this data to course-correct action and drive
innovation if we want to stay ahead in the race against antimicrobial
resistance."

   The estimates for 204 countries and territories were based on data from a
wide range of sources including public health systems, pharmaceutical
surveillance networks, previous studies and more.

   Methodological assumptions had to be made for parts of the world where
data was lacking, especially low- and middle-income countries, the authors
acknowledged.

   They urged more investment in laboratory and research facilities in those
areas.

   - Bacteria-eating virus -

   Antimicrobial resistance occurs as bacteria evolve to be immune to
antibiotics.

   The World Health Organization has declared it a global health crisis,
setting up a task force to study alternative treatments.

   One area of research involves bacteria-eating viruses called
bacteriophages or simply phages.

   A case study published in Nature Communications on Tuesday described how
doctors in Belgium used the therapy to heal a patient whose leg had been
infected for nearly two years.

   Anais Eskenazi, who co-authored the case study and cared for the patient,
described how a laboratory in Georgia found the virus in a sample of sewer
water -- where phages are plentiful due to the masses of bacteria.

   They isolated the one they determined would target the patient's specific
superbug, antibiotic-resistant Klebsiella pneumoniae.

   The treatment could applied intravenously, orally or topically -- on the
outside of the body -- Eskenazi told AFP.

   "In this case, we used the topical administration... the wound was rinsed
with a solution containing phages," she said.

   Combined with antibiotics, the phage therapy healed the infection in three
months, the study said.

   While phages have been used to treat infections in Russia and eastern
Europe for over a century, they are largely overlooked in the EU and US.

   Eskenazi said potential reasons for this could include fear of exposure to
viruses -- though phages pose no threat to people.

   "Bacteriophages are not able to infect human cells, they are specific to
bacteria," Eskenazi said.
