Can solidarity in global health curb the next outbreak? A commentary on mpox

Posted 18/03/2025. Appeals to solidarity are common during disease outbreaks. Yet, what solidarity means and how it is practiced varies across contexts. Caesar Atuire and colleagues bring conceptual clarity by distinguishing between deep and responsive solidarity. They argue that global health needs deep solidarity to curb outbreaks like mpox and to ensure that responsive solidaristic appeals are effective.

Challenges associated with dapsone for leprosy treatment in Indonesia - urgent need for access to alternative antimicrobial drugs

Posted 05/03/2025. Marlous Grijsen and colleagues highlight the challenges associated with dapsone for leprosy treatment in Indonesia. Dapsone, a key drug in multi-drug therapy, can cause life-threatening adverse drug reactions, including dapsone hypersensitivity syndrome and hemolytic anemia. Routine screening could prevent these complications, but in many leprosy-endemic areas, testing and alternative regimens are inaccessible or unaffordable. We call for better diagnostics and alternative treatments to ensure safer care.

Cost-effectiveness of a short-course antibiotic treatment strategy for the treatment of ventilator-associated pneumonia: an economic analysis of the REGARD-VAP trial

Posted 04/03/2025. Previously, the REGARD-VAP trial found that giving patients with ventilator-associated pneumonia (VAP) a personalised, shorter antibiotic treatment was just as effective as usual care. Mo Yin and colleagues showed this approach is also cost-effective in Nepal, Singapore, and Thailand. This approach could save money, reduce antibiotic use, and help policymakers make better healthcare decisions despite some uncertainties.

Dose-Optimization of a Novel Co-Formulated Triple Combination Antimalarial Therapy: Artemether-Lumefantrine-Amodiaquine

Posted 18/02/2025. Emerging artemisinin-resistance in Africa threatens our ability to treat malaria. Joel Tarning and colleagues developed an optimal weight-based dosing of a fixed-dose artemether-lumefantrine-amodiaquine formulation using population pharmacokinetic modelling. Dosing was designed to achieve consistent drug exposure across all body weights. This formulation should simplify manufacturing and improve adherence, when treating resistant malaria.

This is the first free open-source data analysis pipeline allowing anyone to replicate the analysis and develop reference database in-house.

Sustainable antimicrobial resistance surveillance: time for a global funding mechanism

Posted 07/01/2025. The continued costs of a standard national AMR surveillance system are predicted to account for over 5% of the total domestic general government health expenditure (GGHE-D) for 28 LMICs and more than 2% of GGHE-D for 46 LMICs. This high cost is not sustainable without a long-term global financing mechanism. By Liz Ashley

AmpC β-lactamases detected in Southeast Asian Escherichia coli and Klebsiella pneumoniae

Posted 20/12/2024. AmpC β-lactamases are a neglected cause of third generation cephalosporin resistance in Southeast Asia. This collaboration between COMRU, LOMWRU and SMRU showed that AmpC β-lactamases are an important cause of infection, though infections may be going undetected due to a lack of testing resulting in sub-optimal treatment for patients. By Tamalee Roberts

Community engagement to develop a dialogue-drama on adolescent pregnancy in a marginalised migrant population on the Thailand-Myanmar border: an ethnographic approach to participatory action research

Posted 20/11/2024. A participatory-action approach involving community members and adolescents resulted in a dialogue-drama (Karen and Burmese versions) on adolescent pregnancy, contraception, and choice in the event of an unplanned pregnancy. The dialogue-drama augmented discussion of traditionally taboo issues and this ethnographic method is potentially useful for similar global health settings. By Rose McGready

Prevalence and risk factors of vitamin D deficiency among Afghan primary school children

Posted 19/11/2024. Bob Taylor and colleagues determined that vitamin D deficiency is exceptionally high, 85%, in 510 5-15 years-old school children from Kandahar city, Afghanistan. Half had severe deficiency. Older children from poor families with limited outdoor activity and inadequate sun exposure were more likely to be deficient. These data provide evidence for a mitigation strategy.

Prospective clinical surveillance for severe acute respiratory illness and COVID-19 vaccine effectiveness in Kenyan hospitals during the COVID-19 pandemic

Posted 13/11/2024. Ruth Lucinde, Anthony Etyang and colleagues conducted a prospective longitudinal hospital-based sentinel surveillance at 16 public hospitals in Kenya during the COVID-19 pandemic to describe the clinical and demographic pattern of patients admitted with severe acute respiratory illness (SARI), and evaluate COVID-19 vaccine effectiveness. They identified key risk factors for mortality and reported a moderate vaccine effectiveness of 59% against progression to inpatient mortality.

Changing epidemiology and antimicrobial susceptibility of bloodstream infections at a Vietnamese infectious diseases hospital (2010–2020)

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

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.

Non-invasive detection of bilirubin concentrations during the first week of life in a low-resource setting along the Thailand–Myanmar border

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.

Genomic insights unveil the plasmid transfer mechanism and epidemiology of hypervirulent Klebsiella pneumoniae in Vietnam

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.
