New Treatments

Tropical protozoan diseases are currently a major public health problem throughout the world and are strongly linked with poverty, this combined with a lack of commercial markets for potential drugs has created a large burden on the health and economic development of low-income and middle-income countries in Africa, Asia, and the Americas. Due to the low research interest and the high increase of resistance against the existing treatments, as well as increasing inefficiency, toxicity, prolonged treatment schedules and costs, there is an urgent need for cost-effective, safe and easy-to-administer, new effective compounds with novel mechanisms of action. Several studies of crude plant extracts have already identified potential compounds to treat Chagas’ disease, Leishmaniasis, Toxoplasmosis, Giardiasis, and Malaria among other protozoan parasites. Natural compounds of medicinal plants have shown lower toxicity together with higher specificity, creating an optimistic view of new treatments for diseases. Out of 1010 new active substances approved as drugs for medical conditions by regulatory agencies during the past 25 years, 490(48.5%) were from a natural origin.

Immunisation is a cornerstone to primary health care and is an exceptionally good value. The 14 low-income and middle-income countries in the Middle East and North Africa region make up 88% of the region’s population and 92% of its births. Many of these countries have maintained high immunisation coverage even during periods of low or negative economic growth. However, coverage has sharply deteriorated in countries directly impacted by conflict and political unrest. Approximately 1.3 million children were not completely vaccinated in 2017, as measured by third dose of diphtheria–pertussis–tetanus vaccine. Most of the countries have been slow to adopt the newer, more expensive life-saving vaccines mainly because of financial constraints and the socioeconomic context. Apart from the three countries that have had long-standing assistance from Gavi, the Vaccine Alliance, most countries have not benefited appreciably from donor and partner activities in supporting their health sector and in achieving their national and subnational immunisation targets. Looking forward, development partners will have an important role in helping reconstruct health systems in conflict-affected countries. They can also help with generating evidence and strategic advocacy for high-priority and cost-effective services, including immunisation. Governments and ministries of health would ensure important benefits to their populations by investing further in their immunisation programmes. Where possible, the health system can create and expand fiscal space from efficiency gains in harmonising vaccine procurement mechanisms and service integration; broader revenue generation from economic growth; and reallocation of government budgets to health, and from within health, to immunization.

AbstractCryptosporidium is a significant public health problem and one of the primary causes of diarrhoea in humans, particularly in very young children living in low- and middle-income countries. While the zoonotic Cryptosporidium parvum and anthroponotic C. hominis species collectively account for most cases globally, the latter is predominant in low- and middle-income countries. Here, we present a comprehensive whole genome study of C. hominis, comprising 114 isolates from 16 countries within five continents. We detect two highly diverged lineages with a distinct biology and demography that have diverged circa 500 years ago. We consider these lineages as two subspecies, and provisionally propose the names C. hominis hominis (clade 1) and C. hominis aquapotentis (clade 2 or gp60 subtype IbA10G2). C. h. hominis is mostly found in low-income countries in Africa and Asia, and it appears to have recently undergone population contraction. In marked contrast, C. h. aquapotentis was found in high-income countries, mainly in Europe, North America and Oceania, and we reveal a signature of population expansion. Moreover, we detected genomic regions of introgression representing gene flow after a secondary contact between the subspecies from low- and high-income countries. We demonstrate that this gene flow resulted in genomic island of high diversity and divergence, and that this diversity at potential virulence genes is maintained by balancing selection, suggesting that they are involved in a coevolutionary arms race.

Introduction: Malaria and intestinal helminthes infections are major public health problem in low and middle-income countries affecting over 2 million people across the globe. Objectives: This survey was carried out to determine the prevalence of malaria and intestinal parasites among Muslim school children in Port Harcourt, Rivers State. Methodology: Four Muslim schools: kab model school Rumuagolu, Manbaul hikma Eliozu, An-nur school Rumuodomaya and Al-ameen school Eneka. One hundred and fifty (150) blood and stool samples were collected randomly from the pupils (70 males and 80 female; age range 5-12 years) and examined between the Months of May to July 2018. Results: The overall prevalence of 50.7%, and 43.3% was recorded for malaria and intestinal helminthes respectively. The prevalence for malaria was 32.5%, 63.0%, 58.0% and 50.0%. Intestinal helminthes was 30%, 53.3%, 42.0% and 53.0% for kab, Manbaul hikma, An-nur and Al-ameen Schools respectively. The frequency of parasites encountered was as follows, Strongyloides stercoralis 8.7%, Ascaris lumbricoides 14.0%, Enterobious vermicularis 1.3%, Necator americanus 5.3%, Ancylostoma duodenale 4.7%, and Trichuris trichuria 9.3%. Malaria and intestinal helminthes infection was highest in females with 51.2% and 45.0% respectively. Pupils between ages 9-10 had the highest infection rate of (54.0%) for malaria while ages 7-8 had the highest prevalence of 47.7% for intestinal helminthes. Co-infection was 22.0%, 23.0%, 22.0% and 32.0% for kab, Manbaul hikma, An-nur and Al-ameen Schools Respectively. Conclusions: The overall infection for malaria and intestinal helminthes was high. Therefore, regular de-worming of the pupils by parents, and health education are necessary to keep the prevalence in check. This study may also be used to predict risk for communities under consideration.

Road traffic injuries are a neglected global public health problem. Over 1.25 million people are killed each year, and middle-income countries, which are motorising rapidly, are the hardest hit. Sri Lanka is dealing with an injury-related healthcare crisis, with a recent 85% increase in road traffic fatality rates. Road traffic crashes now account for 25 000 injuries annually and 10 deaths daily. Development of a trauma registry is the foundation for injury control, care and prevention. Five northern Sri Lankan provinces collaborated with Jaffna Teaching Hospital to develop a local electronic registry. The Centre for Clinical Excellence and Research was established to provide organisational leadership, hardware and software were purchased, and data collectors trained. Initial data collection was modified after implementation challenges were resolved. Between 1 June 2017 and 30 September 2017, 1708 injured patients were entered into the registry. Among these patients, 62% were male, 76% were aged 21–50, 71.3% were motorcyclists and 34% were in a collision with another motorcyclist. There were frequent collisions with uncontrolled livestock (12%) and with fixed objects (14%), and most patients were transported by private vehicles without prehospital care. Head (n=315) and lower extremity (n=497) injuries predominated. Establishment of a trauma registry in low-income and middle-income countries is a significant challenge and requires invested local leadership; the most challenging issue is ongoing funding. However, this pilot registry provides a valuable foundation, identifying unique injury mechanisms, establishing priorities for prevention and patient care, and introducing the concept of an organised system to this region.

Diabetes is a major public health problem, increasingly affecting low- and middle-income countries. The project CEAD (Contextualizing Evidence for Action in Diabetes in low-resource settings) aims to evaluate the implementation of comprehensive diabetes care in two low-resource settings in Ecuador and to stimulate context-led health systems innovations to improve diabetes care and reduce inequity. The mixed-methods approach includes a 24-month retrospective study to assess the current level of implementation of comprehensive diabetes care and participants will be followed up prospectively for two years to assess changes in healthcare and clinical outcomes from the outset of the research. We will include individuals diagnosed with type-2 diabetes aged over 18 years, who are accessing diabetes care in health facilities in the study districts. Varied stakeholders (patients and family members, community members, healthcare workers and decision-makers) will interpret the underlying causes of the observed weaknesses and propose solutions to strengthen diabetes-related healthcare in focus group discussions (FG). A second set of FG will analyze perceived improvements in healthcare based on prospective cohort findings and consider the success/failure of any context-led innovations occurring throughout the research. Our study will demonstrate how evidence can be contextualized to stimulate local innovations and overcome weaknesses of diabetes-related healthcare in low resource settings.

Infants And Young Children

Safety, efficacy, and cost-effectiveness are paramount to vaccine development. Following the isolation of rotavirus particles in 1969 and its evidence as an aetiology of severe dehydrating diarrhoea in infants and young children worldwide, the quest to find not only an acceptable and reliable but cost-effective vaccine has continued until now. Four live-attenuated oral rotavirus vaccines (LAORoVs) (Rotarix®, RotaTeq®, Rotavac®, and RotaSIIL®) have been developed and licensed to be used against all forms of rotavirus-associated infection. The efficacy of these vaccines is more obvious in the high-income countries (HIC) compared with the low- to middle-income countries (LMICs); however, the impact is far exceeding in the low-income countries (LICs). Despite the rotavirus vaccine efficacy and effectiveness, more than 90 countries (mostly Asia, America, and Europe) are yet to implement any of these vaccines. Implementation of these vaccines has continued to suffer a setback in these countries due to the vaccine cost, policy, discharging of strategic preventive measures, and infrastructures. This review reappraises the impacts and effectiveness of the current live-attenuated oral rotavirus vaccines from many representative countries of the globe. It examines the problems associated with the low efficacy of these vaccines and the way forward. Lastly, forefront efforts put forward to develop initial procedures for oral rotavirus vaccines were examined and re-connected to today vaccines.

SynopsisBackgroundAntimicrobial resistance (AMR) surveillance of bloodstream infections is challenging in low- and middle-income countries (LMICs), limited laboratory capacity preventing routine patient-level susceptibility testing. Other specimen types could provide an effective approach to surveillance.ObjectivesOur study aims to systematically evaluate the relationship between resistance prevalence in non-sterile sites and bloodstream infections.MethodsAssociations between resistance rates in Escherichia coli and Staphylococcus aureus isolates from blood and other specimens were estimated in Oxfordshire, UK, 1998-2018, comparing proportions resistant in each calendar year using time series cross-correlations and across drug-years. We repeated analysis across publicly-available data from four high-income and 12 middle-income countries, and in three hospitals/programmes in LMICs.Results8102 E. coli bloodstream infections, 322087 E. coli urinary tract infections, 6952 S. aureus bloodstream infections and 112074 S. aureus non-sterile site cultures were included from Oxfordshire. Resistance trends over time in blood versus other specimens were strongly correlated (maximum cross-correlation 0.51-0.99, strongest associations in the same year for 18/27 pathogen-drug combinations). Resistance prevalence was broadly congruent across drug-years for each species. 276/312 (88%) species-drug-years had resistance prevalence in other specimen types within ±10% of that blood isolates. Results were similar across multiple countries and hospitals/programmes in high/middle/low income-settings.ConclusionsResistance in bloodstream and less invasive infections are strongly related over time, suggesting the latter could be a surveillance tool for AMR in LMICs. These infection sites are easier to sample and cheaper to obtain the necessary numbers of susceptibility tests, providing more cost-effective evidence for decisions including empiric antibiotic recommendations.

Abstract Background Anaemia has long been recognised as a major public health problem among young children in lower- and middle-income countries and is an indicator of both poor nutrition and health status. There has been little progress towards improvement of anaemia in part due to its complex aetiology. An added impediment to the progress is that the monitoring of anaemia does not routinely target the whole population, with school-aged children (SAC) largely overlooked. Methods We re-examined data on the prevalence of anaemia among children aged <15 y sampled from 2008–2015 in Kenya. Results Approximately one in four Kenyan children aged <15 y were described as anaemic, including 12% with WHO-defined moderate anaemia and 1% who were severely anaemic. Average haemoglobin concentrations increased with age and the risk of having anaemia decreased with age. However, one in five SAC in Kenya were suffering from anaemia; most were either mild (11.4%) or moderately (10.9%) anaemic. Conclusions The monitoring of anaemia in SAC continues to be a neglected area limiting a careful articulation of the need to target interventions in this age group.
