Changing epidemiology and antimicrobial susceptibility of bloodstream infections at a Vietnamese infectious diseases hospital (2010–2020)
OUCRU
Posted 24/10/2024. Duy Pham’s lab performed comprehensive epidemiological analysis of bloodstream infections (BSI) in Vietnam (2010-2020), revealing an increasing trend of E. coli and K. pneumoniae as predominant pathogens. Both showed rising multidrug resistance, primarily affecting elderly individuals with comorbidities. Antibiotic prescriptions declined significantly following control policies. Their work highlights the needs for community surveillance and antimicrobial stewardship to manage BSIs in Vietnam.
A nationwide mixed methods study of gaps and barriers to implementation of antimicrobial stewardship programs in hospitals in Indonesia
OUCRU OUCRU-Indonesia
Posted 23/10/2024. Robert Sinto, Raph Hamers and colleagues conducted a nationwide evaluation of antimicrobial stewardship programmes (ASP) in Indonesian public and private hospitals. They found that to date most hospitals only reached an inadequate or basic level of ASP implementation, and they identified several globally-relevant and context-specific barriers. The paper formulates actions recommended for sustainable improvement.
Genomic insights unveil the plasmid transfer mechanism and epidemiology of hypervirulent Klebsiella pneumoniae in Vietnam
OUCRU
Posted 01/02/2022. Pham Thanh Duy and colleagues at OUCRU have revealed the endemic circulation of fluoroquinolone-resistant extra-intestinal pathogenic Escherichia coli ST1193 in Vietnam, driven by multiple strain importations and sustained transmissions between humans. These organisms have developed resistance to multiple drugs of choice and are major causes of sepsis in neonates and bloodstream infections in adults in this setting.
Genomic insights unveil the plasmid transfer mechanism and epidemiology of hypervirulent Klebsiella pneumoniae in Vietnam
OUCRU
Posted 22/10/2024. Duy Pham's lab investigated hypervirulent Klebsiella pneumoniae bloodstream infections in Vietnam, uncovering high strain diversity likely driven by horizontal transfer of non-self-transmissible virulence plasmids. Plasmid acquisitions led to the independent emergence of MDR hypervirulent strains. Significant gaps persist in understanding community transmission for targeted interventions, especially in Asia where new strains are emerging.
Non-invasive detection of bilirubin concentrations during the first week of life in a low-resource setting along the Thailand–Myanmar border
MORU SMRU
Posted 22/10/2024. Severe neonatal hyperbilirubinaemia is often diagnosed late in low-resources settings because of lack of point-of-care tools. In this study, Germana Bancone and SMRU researchers have evaluated the performance of a transcutaneous bilirubinometer for screening of neonates born along the Thai-Myanmar border. The study was supported by a Wellcome Trust iTPA grant.

Fractional Doses of Pneumococcal Conjugate Vaccine — A Noninferiority Trial
KWTRP
Posted 10/10/2024. Pneumococcal Conjugate Vaccines (PCV) have had a tremendous impact on childhood morbidity but only 2/3 of children receive a PCV. One obstacle to wider protection is cost. Kate Gallagher, Anthony Scott and others at KEMRI-Wellcome Trust Research Programme, Kilifi, Kenya, showed that a 40% fractional dose of PCV13 had non-inferior immunogenicity to a full dose, suggesting similar benefits could be delivered for lower cost.
In-host modeling of dengue virus and non-structural protein 1 and the effects of ivermectin in patients with acute dengue fever
MORU
Posted 09/10/2024. Junjie Ding and the MORU Clinical Pharmacology Team developed an in-host dengue kinetic model to quantitatively predict drug effects in dengue fever. This model offers valuable insights to inform dengue drug development, and shows that ivermectin reduces NS1 but not viral load. The results are published in a leading PK/PD modelling journal, CPT:PSP.

Three patients died; all had advanced HIV co-infection. Viral evolution and its potential consequences should be closely monitored.
Hospital-acquired infections and unvaccinated children due to chronic diseases: an investigation of the 2017–2019 measles outbreak in the northern region of Vietnam
OUCRU
Posted 24/09/2024. Measles-infected children with chronic diseases had lower vaccination rates and a higher proportion of hospital-acquired infections during the 2017–2019 outbreak in northern Vietnam. Early nosocomial transmission was detected before community outbreaks in several provinces. Strengthening hospital infection control and raising awareness about the importance of vaccination for vulnerable groups is essential. By Thinh Ong Phuc

KWTRP
Posted 06/08/2024. Kioko Mwikali, Abdirahman Abdi and colleagues found that the CSF proteome of cerebral malaria is more similar to Alzheimer's Disease than to acute bacterial meningitis, with cerebral malaria showing elevated amyloidosis. This finding might benefit the search for treatment and management of both Alzheimer's Disease and cerebral malaria.
Relation Between the Dantu Blood Group Variant and Bacteremia in Kenyan Children: A Population-Based Case-Control Study
KWTRP
Posted 02/08/2024. Plasmodium falciparum malaria is a strong predisposing factor for bacteraemia. Silvia Kariuki and colleagues investigated the impact of the rare malaria-protective Dantu blood group variant on susceptibility to bacteraemia. We found that Dantu was significantly protective against bacteraemia only during a high malaria transmission period. This suggested that the protective effect of Dantu on bacteraemia is secondary to its protective effect against malaria.
Genetic diversity, determinants, and dissemination of Burkholderia pseudomallei lineages implicated in melioidosis in Northeast Thailand
MORU
Posted 15/07/2024. A recent study from northeast Thailand identified three major bacterial lineages responsible for melioidosis in the region. Each lineage carries unique gene sets that likely contribute to successful dissemination. These genes are expressed under environmental rather than infectious conditions, with one lineage showing overexpression under nutrient deprivation, highlighting environmental persistence is a prerequisite for infection.
