Etiology and management of hospitalized and outpatient diarrhea among children less than 5 years of age in Lambaréné, Gabon

Objectives: Diarrhea remains a significant cause of global under-5 mortality, particularly in SubSaharan Africa (SSA). To reduce morbidity and mortality, the World Health Organization (WHO) recommends oral rehydration salts (ORS), zinc supplementation, and continued feeding or breastfeeding for all children with diarrhea to prevent dehydration and malnutrition; antibiotics only for bloody diarrhea (i.e. probable shigellosis), suspected cholera, or severe non-intestinal infections (e.g. pneumonia or sepsis); and avoidance of antidiarrheals and antiemetics owing to lack of benefit and potential for harm in young children. Gabon is an upper-middle income country in SSA for which there is a lack of recent, high quality data on the etiology and management of childhood diarrhea. This prospective study aimed to describe the etiology and management of hospitalized and outpatient cases of diarrhea in Gabonese children under five years of age. Methods: Children ≤ 59 months presenting to the Albert Schweitzer or George Rawiri Regional hospitals (February-July 2017) in Lambaréné, Gabon were included if they had ≥ 3 liquid stools per day within the past 3 days. Data was obtained via medical records and standardized questionnaires with caregivers. Diarrheaogenic Escherichia coli, Salmonella enterica, and Shigella spp. were detected using conventional culture techniques. Rotavirus, adenovirus, and Cryptosporidium spp. antigens were detected with commercial rapid immunoassays. Multiplex PCR was used for Cryptosporidium spp., Giardia intestinalis, and Cyclospora cayetanensis detection. Results: Forty-five children were included, 34 of whom were hospitalized. Mean age was 12.2 months; 58% were female. 49% were infected with one or more sought-for pathogens, most commonly with Giardia intestinalis (28.9%) or Cryptosporidium spp. (24.4%). 33% and 36% of hospitalized and outpatient children, respectively, received ORS. Zinc was given to one (3%) hospitalized patient and zero outpatients. Antidiarrheals were frequently given to hospitalized (48%) and outpatient (73%) children. Antibiotics were prescribed in 85% and 36% of hospitalized and outpatient cases, respectively, while only 8 children (18%) presented with bloody stools. 79% of children presented with severe acute malnutrition; 21% had never been breastfed. Conclusions: Ongoing education of healthcare workers and communities regarding WHO-recommended management of childhood diarrhea is needed. The overuse of antibiotics observed in this study is consistent with previous reports and is concerning given high levels of antimicrobial resistance in SSA. Strategies to increase provider awareness of indicated uses of antimicrobials in the setting of childhood diarrhea may help limit the spread of resistance

On Prioritising Global Health’s Triple Crisis of Sepsis, COVID-19 and Antimicrobial Resistance: A mixed-methods study from Malawi

Sepsis causes 20% of global deaths, particularly among children and vulnerable populations living in developing countries. This study investigated how sepsis is prioritised in Malawi’s health system to inform health policy. In this mixed-methods study, twenty multisectoral stakeholders were qualitatively interviewed and asked to quantitatively rate the likelihood of sepsis-related medium-term policy outcomes being realised. Respondents indicated that sepsis is not prioritised in Malawi due to a lack of local sepsis-related evidence and policies. However, they highlighted strong linkages between sepsis and maternal health, antimicrobial resistance and COVID-19, which are already existing national priorities, and offers opportunities for sepsis researchers as policy entrepreneurs. To address the burden of sepsis, we recommend that funding should be channelled to the generation of local evidence, evidence uptake, procurement of resources and treatment of sepsis cases, development of appropriate indicators for sepsis, adherence to infection prevention and control measures, and antimicrobial stewardship

Recognising Sepsis as a Health Priority in Sub-Saharan African Country: Learning Lessons from Engagement with Gabon’s Health Policy Stakeholders

Sepsis has been recognised as a global health priority by the United Nations World Health Assembly, which adopted a resolution in 2017 to improve sepsis prevention, diagnosis, and management globally. This study investigated how sepsis is prioritised in Gabon. From May to November 2021, we conducted a qualitative study in healthcare stakeholders at the local, regional, and national levels. Stakeholders included the Ministry of Health (MOH), ethics/regulatory bodies, research institutions, academic institutions, referral hospitals, international funders, and the media. Twenty-three multisectoral stakeholders were interviewed. Respondents indicated that sepsis is not yet prioritised in Gabon due to the lack of evidence of its burden. They also suggest that the researchers should focus on linkages between sepsis and the countries’ existing health sector priorities to accelerate sepsis prioritisation in health policy. Stakeholder awareness and engagement might be accelerated by involving the media in the generation of communication strategies around sepsis awareness and prioritisation. There is a need for local, regional and national evidence to be generated by researchers and taken up by policymakers, focusing on linkages between sepsis and a country’s existing health sector priorities. The MOH should set sepsis reporting structures and develop appropriate sepsis guidelines for identification, management, and prevention

Knowledge and perception on antimicrobial resistance and antibiotics prescribing attitude among physicians and nurses in Lambaréné region, Gabon: a call for setting-up an antimicrobial stewardship program

Background Africa is challenged by the emergence of antimicrobial resistance (AMR). In order to improve patient management and to optimise approaches to curb the spread of antimicrobial resistance, we examined knowledge and perceptions of AMR and antibiotics prescription practices of HCW (healthcare workers) in Lambaréné, Gabon. Methods We conducted a self-administered, questionnaire-based survey in HCW at the regional referral hospital, a medical research centre, and peripheral health care facilities. The proportions of correct responses to questions were determined and compared between physicians and nurses using Fisher’s Exact test. Results A total of 47 HCW took part in the survey. Of those, 64% (30/47) recognised antibiotic resistance as a major public health issue in Gabon, but only 14/47 (30%) recognised it as a problem in their health facility. Of note, 37/47 (79%) recognised excessive use of antibiotics without microbiological confirmation in case of infection, and buying antibiotics without a prescription, as possible cause of antimicrobial resistance. Some HCW (28%; 13/47) reported having prescribed antibiotics because the patients asked for them; and a total of 15/47 (32%) responded that antibiotics could help patients recover faster when added to malaria treatment. Compared to nurses, most of the physicians recognised that excessive use of antibiotics without microbiological confirmation of infection could contribute to AMR spread (18/19 (95%) vs 19/28 (68%); p = 0.028). Conclusion Most HCW recognised AMR as public health issue. However, a quarter of the participants did not know about the causes fostering the emergence of antimicrobial resistance. There is a need to perform regular HCW training in antimicrobial prescription, and to set up an antimicrobial stewardship program

Knowledge of health workers relating to sepsis awareness and management in Lambaréné, Gabon

Background In 2016, the third international consensus definitions for sepsis and septic shock (Sepsis-3) task force provided revised definitions for sepsis and septic shock. This study explores knowledge regarding sepsis among health workers in Lambaréné, Gabon. Methods We conducted a self-administered questionnaire-based survey about sepsis among health workers from the referral regional hospital, the research center, and primary care health facilities in the Lambaréné region. Participants were from the referral regional hospital, the research center, and primary health care facilities. A score of one was given to each correct answer. The global score out of a possible score of twenty was calculated, and the proportion of correct responses was determined. Results A total of 115 health workers (physicians, nurses and assistant nurses) completed the questionnaire, of which 48.7% (56/115) provided a valid definition of sepsis, but 74% (85/115) had never heard about the quick Sequential Organ Failure Assessment (qSOFA) score. The proportion of correct answers was comparable across the three health profession categories. The median global score across all health workers was 11 [IQR, 9-14.5] out of 20. Physicians attained higher global scores [14 (IQR, 11-15)] than assistant nurses [11 (IQR, 8-13), P=0.007]; their global score was comparable to that of nurses. Conclusion There are considerable knowledge gaps regarding sepsis among health workers in Lambaréné, potentially impairing the prompt recognition and management of sepsis. There is a need to establish periodic up-to-date training to improve sepsis knowledge

A comparison of different scores for diagnosis and mortality prediction of adults with sepsis in Low-and-Middle -I ncome Countries: a systematic review and meta-analysis

Background Clinical scores for sepsis have been primarily developed for, and applied in High-Income Countries. This systematic review and meta-analysis examined the performance of the quick Sequential Organ Failure Assessment (qSOFA), Systemic Inflammatory Response Syndrome (SIRS), Modified Early Warning Score (MEWS), and Universal Vital Assessment (UVA) scores for diagnosis and prediction of mortality in patients with suspected infection in Low-and-Middle-Income Countries. Methods PubMed, Science Direct, Web of Science, and the Cochrane Central Register of Controlled Trials databases were searched until May 18, 2021. Studies reporting the performance of at least one of the above-mentioned scores for predicting mortality in patients of 15 years of age and older with suspected infection or sepsis were eligible. The Quality Assessment of Diagnostic Accuracy Studies tool was used for risk-of-bias assessment. PRISMA guidelines were followed (PROSPERO registration: CRD42020153906). The bivariate random-effects regression model was used to pool the individual sensitivities, specificities and areas-under-the-curve (AUC). Findings Twenty-four articles (of 5669 identified) with 27,237 patients were eligible for inclusion. qSOFA pooled sensitivity was 0·70 (95% confidence interval [CI] 0·60–0·78), specificity 0·73 (95% CI 0·67–0·79), and AUC 0·77 (95% CI 0·72–0·82). SIRS pooled sensitivity, specificity and AUC were 0·88 (95% CI 0·79 -0·93), 0·34 (95% CI 0·25–0·44), and 0·69 (95% CI 0·50–0·83), respectively. MEWS pooled sensitivity, specificity and AUC were 0·70 (95% CI 0·57 -0·81), 0·61 (95% CI 0·42–0·77), and 0·72 (95% CI 0·64–0·77), respectively. UVA pooled sensitivity, specificity and AUC were 0·49 (95% CI 0·33 -0·65), 0·91(95% CI 0·84–0·96), and 0·76 (95% CI 0·44–0·93), respectively. Significant heterogeneity was observed in the pooled analysis. Interpretation Individual score performances ranged from poor to acceptable. Future studies should combine selected or modified elements of different scores. Funding Partially funded by the UK National Institute for Health Research (NIHR) (17/63/42)

Reducing the burden of tuberculosis and sepsis in Gabon: Clinical and epidemiological investigations for improved control

Each year, an estimated 1.5 and 11 million people died of tuberculosis and sepsis, respectively. Most cases occur in Low and Middle-Income Countries (LMICs). Gabon is listed in the top 30 tuberculosis/HIV high-burden countries. Studies performed for this thesis investigated the contributors to the burden of tuberculosis and sepsis in Gabon and suggested actions for improved control
